GPS vehicle monitoring composition

The vehicle monitoring structure consists of a three -layer network comprehensive regulatory system formed by the vehicle terminal, the transmission network and the monitoring center to provide functions of vehicle anti -theft, anti -robbery, driving route monitoring, real -time wireless transmission of video images inside and outside the car, To solve the dynamic management of existing vehicles.

The vehicle monitoring uses a vehicle installation of the car video server with 3 to 4 cameras.The video server via EDGE/CDMA20001X/Wi-Fi network. The monitoring center can monitor and transmit real-time monitoring and transmission of images inside the vehicle. It also uses dual-order streaming technology. Local video uses D1 resolution. The network transmission uses CIF/QVGA/QCIF to distinguish the resolutionRate, realize local coding storage and remote storage.

The main composition of the vehicle monitoring system is divided into: vehicle terminal (vehicle video server), monitoring center, transmission network, etc.

GPS vehicle monitoring system working principle

1As well asGPSThe vehicle monitoring system consists of three parts: car host, server and client.The car host is mainly through the global satellite positioning system of the United States (GPS) To determine the position of the mobile target, upload data through the mobile communication network and the global Internet, the server receives positioning data and stores it. The client access the server to extract maps and vehicle positioning information through the global Internet access server.

2, Installed on the vehicleGPSThe receiver calculates the current location of the vehicle based on the received satellite information.GPSExtract the position, speed and time information required in the signal output of the receiver, combine information such as the vehicle identity, and other information to form a data packet, and then through the mobile operatorsGPRSThe network is sent to the monitoring center.The server of the monitoring center receives the data sent by the vehicle machine and extracts the positioning information from it. According to the vehicle number and group number of each vehicle, it is displayed on the electronic map of the monitoring center.At the same time, the system administrator of the control center can inquire about the operating conditions of each vehicle and reasonably dispatch the vehicle according to the traffic flow.

3The principle of the vehicle monitoring system determines that the system needs to rely on three networks to run reliable: the global satellite positioning system in the United States, China Mobile, China MobileGPRSThe global Internet network based on different operators.

4The vehicle monitoring management system consists of the vehicle machine and the monitoring and dispatch center. The information transmission depends on the public public network system. It does not need to be established alone, and also saves a lot of maintenance funds.

5, Vehicle Safety Monitoring Management System is inGSMOperation within the effective range of the public network, all car targets can be effectively tracking management within the scope of the network roaming range.GSMThe extension of technology will promote the simultaneous development of vehicle safety monitoring and management systems.The expansion of the network means the expansion of the actual tracking range.

6The vehicle safety monitoring management system adopts a multi -level architecture, which can be large or small. From groups to families, they can conduct various types of real -time tracking management of different natures for different overalls.The equipment is simple, the cost is moderate, and it is convenient to use.

How much is the price of rice seeds a pound

Throughout the price trend of rice seeds in recent years, rice prices will still be relatively stable and will not cause great floating.

1. The joy of rice planting

First of all, according to previous policies, whether the price of rice is canceled is not yet officially announced, and the possibility of recently canceling the price of rice protection.Therefore, in order to protect the interests of farmers and prevent it"Valley is hurting farmers", and the country will still be carried out the minimum protection price of rice, but it is only slightly reduced!

The Grain Industry, "The "Thirteenth Five -Year Planning Outline" proposes that during the "Thirteenth Five -Year Plan" period, we must continue to implement and improve the minimum purchase price policy of rice and Wheat, actively and steadily promote the reform of the corn collection and storage system, adjust and improve the soybean target price policy, improve rapeseed acquisition of rapeseed acquisitionspolicy.

Secondly, production investment.Facing the falling price of food prices this year, the overall sales of the Fertilizer industry are not optimistic enough. The prices of two Fertilizer species such as Fertilizer Compound fertilizer and Urea as rice have decreased to varying degrees than the same period last year.Large households reduce the burden on cost investment.

Second, the worries of rice planting

The area of rice planting area has increased, which is pressured by the supply of raw grain in the future.Some farmers in the Northeast will have a high enthusiasm for drought and water. Among them, the southeast of Heilongjiang, Mudanjiang, Jiamusi, Qitaihe, Shuangyashan and other places have performed more obvious. It has been slightly increased by the Northeast water field contracting land.Rent on the ground500-700Yuan is not waiting.

The increase in planting area and the increase in land rental costs may make the rice planting benefits less than expected. It is recommended that farmers need to follow the trend and combine the local actual situation to choose a variety that suits them.

In summary, although there are still many uncertainties in rice planting.However, in the context of the continued implementation of the minimum protection price policy of rice, farmers should do even if they are selected and planted, they should master each production link to fundamentally ensure the quality and output of rice.Because from the changes in the market price trend of the rice market, the universal, weak, and high -quality and high -quality prices are always changing the market.In the long run, rice will eventually leave the coats protected by the national government and comply with market price changes, so that lower rice will not allow more cheaper rice to enter the Chinese market.Therefore, doing a good job in the formation and directional sales of farmers and enterprises can make the people truly realize the meaning of unwavering food in their hands.

In the end, under the situation of the policy as a whole, it should be more concerned about the expensive inventory speed of the national reserve rice. If the huge inventory cannot be digested, the road to the collection and storage of rice is still difficult.

How to buy rice seeds

The purchase of rice seeds should choose the excellent varieties that are suitable for planting according to the opinions of local climate, soil and ecological conditions and agricultural technology.In order to prevent buying fake and inferior seeds and preventing seed quality disputes in case of preparation in the future, the following points should be achieved.

According to your planting needs, ask about the types, characteristics and planting essentials that are suitable for the planting of your fields, and ask for related cultivation technical materials as much as possible.

See if the "four certificates" (seed business license, seed quality qualification certificate, seed production license, and business license) are complete, whether the seeds are consistent, and whether the seed packaging is standardized.The rice seeds of regular companies are all packaged in small Bags, which should be marked with "variety names, manufacturer names, address and contact information, production date, production license number, business license number, variety review number, net content and quality standards, etc."" ".

Finally, to save seed packaging and seed purchase invoices, in case the seed quality disputes occur, claims are based on this.

First, look at the seed label: To buy seeds, first look at the label inside and outside the packaging.According to the relevant provisions of the "Management Measures for Crop seeds", hybrid rice seed labels shall be marked with relevant indicators such as the name of the variety and variety review numbers.However, special seed seeds such as red rice seeds and black rice seeds generally do not have strict requirements on this item, and the market audience is relatively small

Second, look at the neatness of seeds: Hybrid rice seeds mixed with other rice are not neat.

Third, look at the grain shell, blame: The physiological miscellaneous colors such as the slightly uneven yellow brown on the hybrid rice seed valley shell are normal.

Fourth, look at seed clarity: Different types of rice seeds have corresponding standards.

Fifth, look at the seed water content: The simple method is to bite the grains with the teeth. If there is a sharp sound, the content is basically normal (13%Inside); if there is no crispy or tanned cross section, the moisture content of the seeds is generally higher than the normal standard.

[Outdoor shoes] The difference between Outdoor shoes and sneakers

Think of mountaineering shoe laces as a major topic to study, and many people will definitely disdain. A piece of laces and small dishes are indeed.shoelaces.But for outdoor sports or Hiking, we will give you a few better and stronger shoelaces for different Climbing shoes.

Outdoor shoe lace

1. hook quickly (A)

Like the top hooks that usually around the top layer, then cross the lace cross, and then tie the hook into an 8 -shaped type.

2. Pass through the holes of the shoe (b)

b1. A ring on each strap and stuff them over the metal holes at the top.

b2. Pass the end of the shoelace through the ring buckle of another shoelaces and tighten it.

Tightening the laces can not only protect the heels, but also greatly reduce the possibility of bubbles.However, doing so may also compress the toes, and it will also scratch the instep in the long -term exercise, especially the boots that are not very comfortable in the pad.The following two methods will make you adjust the tension of your toes and ankles to play a protective role, which does not hinder blood reincarnation.

3. Appropriate looseness (C)

c1. Adjust the band to the right looseness.In front of the ankle, the two laces were entangled around several times.

c2. Even if you pull the ankle tightly, the front of your feet should be kept loose.Remember, when you wear thicker socks, you need to adjust the shoelaces in the front of your feet.

4. Double -layer straps (D)

If you may have to prepare two shoelaces or break the shoelaces into two, tie the upper and lower end of the boots.This layered structure allows you to adopt different tight strategies for different situations.If you hope that the ankle is tight, you can tighten the shoelace of the department. If you feel that the foot department is too crowded, you can properly relax the lower department's shoelace.

precautions

Protection of ankle safety

This principle is used in Hiking in a location full of random stones and branches. There are many sharp stones and branches in this location. At this time, if you tie the shoelace tightly, the tongue will top to the ankle part, blocking may be injured.Your branches and stones.Accurate shoelaces can prevent the soles of the soles of the feet from blistering and a heel abrasion, which will ensure that the shoelaces are tranquil and practical.

mountaineering shoes, Hiking shoelaces:

The difference between Outdoor shoes and sneakers

1 mountaineering shoes are relatively high in waist, which is not easy to launch and neck.

2 The soles of mountaineering shoe seem to be different in materials, the grip is better, and it is basically tire pattern.

3 mountaineering shoes are generally laces, which is not convenient, but it is very practical and can protect the ankles and necks.

The 4 upper is generally good Skin. Even if it hit the stone, it is not easy to hurt your feet.

5 generally does not need to be cleaned, just brush it with a brush.

6 foots can not be bent upwards, and you cannot walk on the mountain road on a large angle

The primary feature of real Outdoor Climbing shoes is superior waterproof function, which is not available in most ordinary sneakers.On the basis of comfortable, professional mountaineering shoes should be waterproof and breathable. If it is in winter, it is very dangerous to board the shoe with poor waterproof performance. It is 23 times that of dry feet to dry feet, so it is easy to frostbite.Neither the traditional oil -soaked leather and surface dipping agents can perfectly solve the waterproof problem. What really achieves is the waterproof and breathable film such as GORE -TAX.GORE-TAX bronze medal has almost become a symbol of the quality of hiking shoes. It is usually expensive and often exceeds 1,500 yuan. However, some humble specialty stores can also use 800-900 yuan to buy good quality.

What are the fabrics in the Swimsuit

1, Du FangLaika

Du FangLycra is a artificial elastic fiber with the best foam of elasticity. It can be freely extended by 4 to 7 times. Extension is excellent.Suitable for blending with a variety of fibers, which can strengthen the advantages such as drooping texture, anti -wrinkle and other advantages.DuPont Ledica, which contains anti -chlorine, will make swimwear a longer service life than a Swimsuit with ordinary materials.

2. nylon fabric

The fabric obtained by blending or interweaving the nylon long silk or short fiber and other fibers has the characteristics and strengths of each fiber.For example, the sticky/Jinhuada, using 15%nylon and 85%of the adhesive blending into a yarn, which is doubled by density than weir dense.Wrinkle, dampness drops, and it is easy to droop when wearing.In addition, there are varieties such as sticky/Jin Fanling, sticky/brocade/hair, etc., all commonly used fabrics.

The most common nylon products in the market are nylon 6 and nylon 66.

nylon 6: The full name is polybioneam fiber, which is concentrated by the amide.

nylon 66: The full name is Ji Ji gyacinhamine fiber, which is concentrated from the gimysic acid and the hexyramine.

The common characteristics of nylon 6 and nylon 66: Poor photosyntynce resistance. Under the long -term sunlight and ultraviolet light, the strength decreases and the color is yellow.Huang, intensity and extension decreased significantly, and the contraction rate increased.

nylon 6 and 66 long silk has good low temperature resistance. When it is below minus 70 C, its rebound changes are not great.Its DC conductivity is very low, and it is easy to generate static electricity during the processing process. Its conductive rate increases with the increase in moisture absorption, and increases according to the index function rules with the increase of humidity.nylon 6 and 66 long silk has a strong ability to resist microorganism. Its ability to resist microbial effects in mud or alkali is second only to chlorine.In terms of chemical properties, nylon 6 and 66 long silk has the effects of alkali resistance and reducing agent, but has poor performance in acid resistance and oxidant.

3. Polyester fabric

Polyester fabrics are a lot of chemical fiber clothing fabrics in daily life.Its biggest advantage is that wrinkle resistance and preservation are very good, so it is suitable for coats.

Polyester fabrics have poor moisture absorption, dressed in stuffy, and easy to use electrostatic, dirty dust, affecting beauty and comfort.However, it is easy to dry after washing, and the wetness is almost not reduced, does not deform, and has good washing performance.

Polyester fabrics have high strength and elastic recovery capabilities. Therefore, it is firm and durable, anti -wrinkle and refractory.

Polyester fabric has a good light resistance. In addition to the worse than acrylic, its sun resistance is better than natural fiber fabrics.Especially the ability to resist behind the glass is very good, and it is almost comparable to acrylic.

Polyester fabrics are resistant to various chemicals.The degree of acid and alkali is not greatly damaged, and they are not afraid of mold, not afraid of insects.

Polyester is the best thermal resistance in the fiber fabric. It has thermoplasticity. It can be made of pleated skirt and long -lasting.At the same time, polyester fabrics have poor anti -melting properties, and they are prone to forming holes such as ash and Mars.Therefore, we should try to avoid contact with cigarette butt, sparks, etc. when wearing.

one,The role of Potassium fertilizer

Applying Potassium fertilizer can promote the photosynthesis of crops, promote the results of crops and improve the ability of crops to resist cold and disease, thereby improving agricultural output.Potassium exists in the form of free potassium ions in the plant, which can promote the metabolism of carbohydrates and nitrogen; control and regulate the activity of various mineral nutrients; activate the activity of various enzymes; control nutrients and water transportation; maintain the cells of cells; maintain the cells of cellsInternal pressure to prevent the plant from withering.

1. Promote the activation of enzymes

The activation of enzymes is one of the most important functions in potassium in plant growth. It has been found that potassium is the activator of more than 60 enzymes.therefore.Many of the metabolism processes in potassium and plants are closely related, such as: photosynthesis, breathing, and carbohydrates, fat, protein synthesis, etc.

2. Promote the transportation of photosynthesis and optical products

Improve photosynthetic efficiency; regulate the opening and closing of the gas holes, control the entry and exit of Co and water; Promote the synthesis of carbohydrates and accelerate the flow of photosynthesis products.

3. Promote protein synthesis

The intake and operation of the key ingredients of protein synthesis; is closely related to the synthesis process of protein.

4. Enhance the anti -reverse nature of plants

Potassium can reduce the soluble amino acids and monosaccharides in the body, increase cellulose, and thick cell walls; potassium accumulates the accumulation of crop root system to produce permeable pressure gradients to enhance water absorption; potassium can cause the crop blade air to close the air pores to prevent water from water prevention loss when drought and water deficiency.EssenceTherefore, potassium can enhance the ability of disease resistance, cold, drought resistance, anti -falling and salt resistance of crops.

5. Improve the quality of crop products

increase the protein content of grain crops, the crude fat and palm acid content of oil crops, the content of starch and sugar content of potato and sugar crops; increase the length, strength, and fineness of the fiber crops and cotton fiber;The content of vitamin C; improving the shape, size, color and flavor of fruit vegetables, and enhance their storage resistance.

2. agricultural application of potassium Fertilizers

When crops lack Potassium fertilizer, they will get "cartilage disease" and easily fall down. They are often called "quality elements" by germs of pests.Its role in the quality of crop products is: can promote the use of nitrogen better, increase the content of protein, and promote the production of sugar and starch;Beautiful color; increase the oil content of oil crops and increase the content of vitamin C in fruits; Accelerate the maturity of fruits, vegetables and other crops to make the maturity period consistent;storage and transportation period; Add the strength, length, and fineness of cotton and hemp crops, and the purity of the color.

What are the types of potassium Fertilizers?

Potassium fertilizer can be divided into two categories: industrial Potassium fertilizer and other potassium Fertilizers.Among them, Potassium fertilizer of industrial industrial is: potassium sulfate, potassium chloride, potassium nitrate, potassium phosphate, potassium magnesium Fertilizer, potassium and calcium Fertilizer.Other potassium Fertilizers include plant ash, kiln ash Potassium fertilizer, organic Potassium fertilizer, etc.

1. Potater sulfate Fertilizer

Potater sulfate Fertilizer generally refers to potassium sulfate magnesium Fertilizer.Contains K2O 50%to 52%, easy to dissolve in water, physiological acidic Fertilizers.After the soil is applied, the potassium is ionic, and part of the plants are directly absorbed and utilized, and part of it is exchanged with the cation on the soil gum, and calcium sulfate and sulfuric acid are generated.Therefore, after a large amount of potassium sulfate is applied to prevent soil plate knots, on the one hand, Organic fertilizer can be applied. On the one hand, lime can be applied to neutralize acidity.

The role of potassium sulfate Fertilizers is based on base Fertilizer and topdressing.Because potassium moves in the soil, it is more suitable for basic Fertilizer.When topdressing, we must apply the dense layer of the crop system.Potassium sulfate is particularly effective for sulfur crops such as the family. Due to its high price, farmers can choose potassium chloride as much as possible in addition to avoiding chlorine crops.

2. Potassium chlorine

Contains K2O 50%~ 60%, easy to dissolve in water, fast Fertilizer, physiological acid Fertilizer.Calcium chloride will be generated in a neutral soil, causing calcium loss; calcium carbonate in lime soil reacts with potassium chloride, which can neutralize and release effective calcium; hydrochloric acid will be generated in acidic soil.Enhance the soil acidity, increase acid and aluminum poisoning, and use lime and Organic fertilizer.

Potassium chloride can be used as base Fertilizer, topdressing, not suitable for planting, and should not be applied to avoid chlorine -alkali -alkali land.Cotton -and -linen fiber crops can improve products and quality.

3. Potassium

It contains 13.5%nitrogen nitrogen and 46%of potassium containing potassium. It is a chemical neutral and physiological neutral Fertilizer. It has good water -soluble and is applied for a long time to cause soil acidification.It is suitable for the expansion of vegetables and fruit trees to the early stages of coloring, which can promote the expansion of pulp cells.Because it contains nitrate nitrogen, it is not recommended to use it in the later stages of coloring, which is easy to cause returning to green.

4, grass and gray

It contains a variety of plant gray elements, including: potassium, calcium, phosphorus, magnesium, sulfur, iron, silicon and other plant nutrient elements.Among them, potassium exists in the form of potassium carbonate, potassium sulfate, and potassium chloride, and phosphorus exists in the form of weak acid -soluble phosphorus.It belongs to alkaline Fertilizers.Do not mix with ammonium nitrogen Fertilizers.It should not be mixed with organic Fertilizers such as Fertilizer, fecal urine, and can easily cause volatilization of nitrogen.Sodium and chloride ions in the plant ash in saline -alkali land are easy to increase soil salt as Fertilizer.

Herbal ash can be used as base Fertilizer, topdressing, and planting Fertilizer.The amount of Fertilizer Fertilizer is 50 ~ 100 kg/mu, as the amount of Fertilizer is 50 kg/mu. It can be mixed with 2 to 3 times before application.Nutrition solution is sprayed with leaf surface.

5. Phosphorus and Potassium fertilizer

The potassium ore containing (phosphorus) is broken to about 100 mesh, and the balance of the sieve is less than 15%.It is an auxiliary material, and its proportion is mineral powder: auxiliary materials = 85 95: 2.2 5; the biochemical reaction is performed in the reactor after the ingredients.After the reaction is completed, the granules can be made according to the distribution ratio.

6, potassium dihydrogen phosphate

After the potassium dihydrogen phosphate melts, it is a transparent liquid, and it is opaque glass -shaped after curing.Potassium dihydrogen phosphate is an efficient phosphorus and potassium Compound fertilizer, which contains about 52%of phosphorus and about 34%of potassium.Potassium dihydrogen phosphate is suitable for various types of economic crops, including food, fruits, vegetables, etc., which can generally be used before and after flowering, color period, and fruit picking.After the use of potassium dihydrogen phosphate, it has a significant increase in crop yield, improvement of crop quality, and improving crop resistance and disease -resistant pests.
