1. How to deal with the GPS positioner being demolished by the thief

GPS The positioner was removed by the thief: you can pass GPS If you set a mobile alarm, you will automatically send a message to your mobile phone, and directly call the police after receiving the information.Of course, the most important thing is to prevent the car from the car GPS The positioner was demolished by the thief.

GPS The positioner is currently widely used and very common. In the automotive industry, it is an indispensable anti -theft positioning equipment. It plays an important role in vehicle management and vehicle anti -theft. GPS The positioner is a very advanced risk control equipment in some industries, but in specific industries, there is no secret at all, and it is inevitable to be demolished. So how to prevent GPS The demolition of the positioner is a problem that the practitioners have to consider.

So how to preventGPS What about the locator?prevent GPS What are the effective methods of the locator?

1 , Optional anti -demolition type GPS The positioner increases the difficulty of demolition when the equipment is manpicable.

2 2. Select the backup power supply GPS When the positioner is destroyed, it can still be located in a short time when the external power supply is destroyed and alarm information is issued.

3 , installation is as hidden as possible.Installing the device in the place where it is not easy to be discovered in the car.

4 After removal, you can use the track playback function to find the activities of people or vehicles.

5 2. In the case of conditions permit, two can be installed GPS The positioner, the thief took it lightly after removing one, often not to find another one.

two,GPS What should I do if the positioner fails?

(1) The phone has just charged the phone bill, but it still shows why it is offline?

answer:1 After the payment is re -paid, the operator will be twenty four Re -open you within hours sim Stuck GPRS Function, please confirm first GPRS Has it resumed;

2 ,confirm GPRS Have been opened GPRS After that, please restart your phone.

(2) Why is the newly installed equipment displayed in the field?

answer:1. 1. If the vehicle is installed, the "static" state is displayed on the platform, but it is still displayed elsewhere on the map.This is because after the device is installed, the vehicle has been in a static state. When the device is static, it will not transmit to the server GPS (Save traffic considerations).This phenomenon is because the device has not yet passed to the server without the latest positioning data, showing the old positioning data.So I see the old location data.

Solution: Please drive the vehicle out of the empty area for a while. When the vehicle has movement, the latest positioning data is on the server, and you can see the accurate position.Essence

2. If the car is installed on the platform, display "offline" or "not online".This is because the device has not connected to the server, GPS The positioning data was not uploaded to the server, and I saw the old positioning data.

(3) May I ask the base station(LBS) Positioning is always drifting to a fixed place, and the distance is too large. What is the reason?

Answer: The base station positioning is decisive and the base station and the base stationGoogle Whether the maps are the same in synchronization, some new base stations or base stations after moving are on Google There will be drift phenomenon if there is no timely update, only wait Google Regularly update

(4) Why does the data in Running statistics do not match the actual situation?Mileage statistics do not match the actual mileage?

Answer: The operating statistical function on the monitoring platform is based on the location information of the locator uploaded to the monitoring platform.The location information of the positioner may be restricted by factors such as signals, environment, faults.

In other words, if the positioner is offline or unpreplace, and there is no accurate location data, the data Running statistics may have some errors.Therefore, the operation statistics on the monitoring platform can only be used for reference.

(5) After remote oil -breaking, why can the vehicle start?

Answer: After the remote oil is broken, the positioner must be cut off when the following conditions are met:

1 The wiring of the GPS positioner is correct, and the wiring of the wiring diagram of the instruction manual.

2 The positioner is working normally, in the state of "static" or "driving", and the vehicle speed is lower than 20 Below kilometers.

If the positioner is offline, unlocking or vehicle speed is higher than the speed of the vehicle is higher than20 More than kilometers, even if the remote oil -off power is successful, the positioner will not cut off the oil.

1. The composition of the GPS map

The GPS map is a brand new geographical information carrier produced by the development of computer technology. The GPS map is born out of the map, presented the map in a digital manner, and can only be used in the computer.GPS maps have the functions of displaying, transmission and analysis. GPS maps can provide better presentations than traditional maps, such as enlarged, reduced, roaming, search, and path planning.

2. The difference between GPS map and traditional paper map

The conventional paper map emphasizes the data carrier, symbolization, and display. It is one of the roots of the development of GPS maps, and the GPS map focuses on analysis. Its expression method is much stronger than traditional maps. It has the following characteristics:

A. Integration of sound, graphic and digital multimedia, combine the intuition of graphics, the accuracy of numbers, the guidance of sound, and intimacy, make full use of the user's various sensory.

B. Inquiry retrieval and analysis function can support two -way retrieval from map graphics to attribute data and attribute data to graphics data.

C. Graphic dynamic changes function, from opening window scaling, browsing reading and other basic functions to the end of the animation function, multi -dimensional animation graphics simulation, etc.

D. With a good user interface, the use of users from the map generation process.

E. The multi -level ratio is converted from each other. It can match the screen content of the screen to perfectly match the current proportion, and automatically use the choice or synthesis of the compatibility of the ratio to the scale.

3. GPSHow is navigation electronic map collected and processed?

There are many collection methods for aviation electronic maps. There are mainly. Through remote sensing satellite pictures, analysis of the road network. In addition, based on the purchase and mapping unit from various places, the accuracy of the map is compared.By parsing through unmanned aircraft aerial pictures to obtain map data, and then from the national basic geographical information center activity related information;

The other is to collect on the spot, using artificial and vehicles for field collection and taking pictures to obtain map information.In these collection methods, there are only third types. The map data obtained on the spot is the most accurate and detailed.At present, there is only Ruitan Wanfang's Taoist Map of Ruitan Fang. In addition, many other companies have started to collect on the spot, but it is already later than Ruitanfang in terms of time.4Year.

[Types of warm and warm box] Classification of cold and warm boxes of car warm and warm boxes and compressed locomotive refrigerators are better

Working principle

In addition to the "refrigeration" effect using semiconductor cooling boxes, it can also take into account the heating effect, but its "refrigeration" effect is far less than the refrigerator that uses the principle of compressor.It is only about 20 C than the ambient temperature, so it can only have the effect of cooling.

The refrigerator using the compressor is the real Car refrigerator. In addition to the fast cooling speed, some products can even reach -18 C's freezing capacity.However, its disadvantages are also very obvious. It does not have the heating function, the price is much higher than the warm and warm box, and at the same time, there are many restrictions such as direction (upside down) in the use.

Functional design

In addition to the different working principles, there are some differences in the functional design of these two types of car refrigerators. We also need to brighten our eyes to distinguish when selecting, so as not to affect the actual experience and effect.

Compared with the high price, using a compressed Car refrigerator with a compressed machine, the cooling and cold box of semiconductor refrigeration has absolute advantages in terms of price.At present, the price on the market ranges from tens to hundreds of yuan, and the low price can be accepted by most consumers.

The semiconductor refrigerator is also called an electronic refrigerator. It is different from other refrigerators that use compressors. The principle of semiconductor refrigeration is used. The principle of Parrad Patch is used by a smaller semiconductor chip.The medium -current circuit releases heat at the metal joint of the node when passing through the node, and achieves the ultimate goal of refrigeration and heating through different current flows.

When this semiconductor refrigerator is working, there is no vibration of any other mechanical components except the heat dissipation fan, and low noise, long life, and non -wear are also the biggest feature.However, its disadvantages are also very fatal in the eyes of many people. Compared with good heating ability, its refrigeration effect is poor and does not have the refrigerator of the compressor refrigerator. Generally, the ideal refrigeration temperature is only about 20 C.

With the continuous improvement of technology, some manufacturers upgrade the refrigeration capacity of traditional cold and warm boxes by increasing the area of refrigeration film, but it is still affected by the great ambient temperature. In addition to the refrigeration speed, it is better than using a single refrigeration system.Fast, there is no essential improvement in refrigeration ability.

Therefore, this kind of warm and warm box is more suitable for use in ordinary household cars. After all, compared with the more than the cabin of the cab, the space of the car is much smaller, and the air conditioning refrigeration effect is more obvious, making the working environment of the warm and warm box lower."Refrigeration effect" is more obvious.

In addition, we also need to pay attention when buying. At present, some vertical warm and warm box that supports the dual -use of the car households is used as a flat door design, and except for magnets on the door, there is no door lock.The sealing effect is easy to condense the moisture in the external air, so that the embarrassing situation of stagnant water around the refrigerator will seriously affect the daily use experience for a large vibration truck cab.Therefore, we should try to buy those who open the door and the bottom with a fully enclosed crooked warm and warm box.

The Car refrigerator that uses a compressor method is the same as ordinary household refrigerators in principle. The process of continuous circulation such as compression, condensation, expansion, and evaporation of internal refrigerant is used to reduce the internal temperature inside the refrigerator.It is just out of portability, and its volume will be even more compact.Because its core components are compressors, it is much more expensive than semiconductor refrigerators.

On the other hand, compared to the real and durable warm and warm box, the compressor refrigerator is relatively "delicate". Although some products claim that its compressor can work normally under 45 , we also need to pay attention to daily use in daily use.Avoid accidents such as bumps and flipping.

Having said so much, many people may ask why some cold and warm box claims to reach the refrigeration capacity of below zero X , but it is far from the actual use?Because some people ignore a factor, that is the ambient temperature.Especially for the cold and warm box, the cooling results of the ambient temperature at 50 C and 25 C are very different. If the refrigeration capacity of 20 C, the final refrigeration result of the two will be as much as 25 C.

Comparison

The price of the "warm and warm box" is basically below 1,000 yuan, but the cooling effect can only reach the point of cooling, suitable for some areas with low requirements and low environmental temperature.Lost meaning;

Compressor vehicles carry refrigerator: The price is basically above 2,000 yuan, but the cooling effect is good, it can freeze, there is no problem with ice cream, ice cream at all, and even drink iced (iced) drinksIn high areas, even if the ambient temperature exceeds 37-38 degrees, or even more than 40 degrees, the temperature can still reach -10 degrees when it is filled with things.

Pay attention to the use of car refrigerators

Select the right capacity according to actual needs

Do not cover the body's heat dissipation holes to avoid affecting its heat dissipation ability

Do not store magnetic objects in the warm and warm box, so as not to affect the effect of refrigeration chip

Need to clean the inside of the refrigerator regularly to avoid bacterial breeding

When switching from refrigeration to heating, you need to wait for the internal recovery of the ambient temperature

Try to choose products with low voltage protection (battery protection) function when buying

If 24V power supply is not supported, you need to buy antihypertensive equipment (24V to 12V)

It is best to pull out the refrigerator power supply when stopping

When using a compressor refrigerator, fix it in the car, avoid inverted and obliquely.

Do not put carbonated drinks and beer for a long time in the frozen area of the compressor refrigerator, which is dangerous to explosion.

[GPS positioner] How to prevent the installation of the GPS positioner prevent the car GPS locator from being demolished by the thief by the thief

The GPS positioner is currently widely used and very common. In the automotive industry, it is an indispensable anti -theft positioning equipment. It plays an important role in vehicle management and vehicle anti -theft.The GPS positioner is a very advanced risk control device in some industries, but in specific industries, there is no secret at all. It is inevitable that how to prevent the demolition of the GPS positioner is a problem that the specific industry practitioners have to consider.Essence

So how to prevent the GPS locator from being demolished?What are the effective ways to prevent the GPS positioner from being demolished?

1. The anti -demolition GPS positioner can be selected. When the equipment is human destructive, it will increase the difficulty of demolition.

2. Use a GPS locator with a spare power supply. When the external power supply is damaged, it can still be located in a short time and issue alarm information.

3. installation is as hidden as possible.Installing the device in the place where it is not easy to be discovered in the car.

4. After removal, you can use the track playback function to find the activities of people or vehicles.

5. In the case of conditions permit, you can install two GPS locors. After the thief is removed, the thief is taken lightly, and often does not find another one.

The GPS positioner is the terminal of the GPS module and the mobile communication module. It is used to transmit the positioning data obtained by the GPS module through the mobile communication module (GSM/GPRS network) to a server on the Internet, which can be realized on the computerQuery terminal position.

installation method

The external power supply GPS positioner must connect to the car power supply before it can work for 24 hours. Generally, it is impossible to use this product to track other people's vehicles.Because it is necessary to access it with the car power supply, the difference is generally a plug -in locator.Therefore, it is not recommended to use a plug -in power supply.

installation path

1. If you understand the electricity, you can install it yourself. In fact, as long as you find the positive and negative electrodes of the car power supply, the negative electrode is very easy to find.Go to the battery;

2. It is best to connect to ordinary electricity, which is not affected by the car key switch. The power cord directly attracted from the car battery;

3. Note that the GPS positioner has a light side to the sky. Do not keep the metal object on this side of the sky to block the internal GPS antenna. It also receives a satellite signal of 20,000 kilometers away;

4. You can also ask the relevant technical personnel to install it, and the charges depending on the specific local situation!

installation location

1. The front windshield above the windshield;

2. The hidden part of the decorative board below the front windshield;

3. The hidden part of the front instrument panel;

4. In the door partition;

5. The decorative board below the windshield;

6. In the front bumper, pay attention to waterproof;

7. Under the wiper board, pay attention to waterproof.

Note: If the windshield is pasted with a metal insulation layer or heating layer, the GPS receiving signal will be reduced, causing GPS to work abnormal.At this time, pay attention to replace the equipment installation location.

installation point

1. In order to avoid the destruction of the thief, the equipment selection should be as conceived as much as possible;

2. Avoid putting with the launch source, such as wireless reversing radar, anti -theft, and other vehicle communication equipment;

3. You can use tie -tie fixing, or use wide beach cotton to stickers with double sides;

4. There are GSM antennas and GPS antennas in the device. When installation, it should be guaranteed to be upward (towards the sky).
