1. precautions for buying GPS navigation equipment

1. Look at the effect and workmanship of the car navigation instrument.Observe whether the screen display is clear, whether the operating response is sensitive, the accuracy is good or bad, whether it is a capacitive screen or a resistance screen. The cheap product is generally a resistance screen, and the response speed is slower than the capacitive screen.See if the screen and the body joint are connected tightly, and the gap is not a good product.After turning on the side, do you have light leakage on the screen.

2. Select the navigation product with the built -in map with the "China navigation Electronic Map Qualification Certificate".Many manufacturers now do not have the "Chinese navigation Electronic Map Qualification Certificate", and they are also providing map navigation. Many navigation errors have occurred.

3. Is it the latest?Be careful to sell the eliminated car navigator product. It is best to ask before buying.The latest is the four -generation chip and autonomous chips, such as Garmin.

4. Finally recognize the anti -counterfeiting logo.Free upgraded genuine maps generally have anti -counterfeiting signs on the body's body. When the owner and friends buy a car navigator, you can query according to the phone, website, etc. on the logo.

How to use Jiaming Positioner

(1) GPS correction

There is no mainland coordinate system in Jiaming GPS. The default of the machine is the WGS84 coordinate system, which needs to be corrected to the coordinate system that matches the topographic map.The specific operation steps are as follows:

1. First set the parameters inside the GPS receiver to "0", that is, DX = 0, DY = 0, DZ = 0, DA = 0, DF = 0, where DX, DY, DZ are the same two coordinates of the same point.The system three -dimensional coordinates value, DA is the two -coordinate system long -axis difference, DF is the difference between the flat rate of the two coordinate systems.

2. Use the GPS receiver to observe the coordinates of the known triangle point, and find their respective differences according to the observation results and the known coordinate values, and take their average value as a correct value of DX, DY, and DZ.

3. The parameters of the receiver DX, DY, and DZ that have been observed are set to the number of corrections that have been obtained, and DA and DF are set to the corresponding difference, that is,

A (84) a (84) -a (54) = DA = -10

(8484) - (5454) = DF = 0.0000005, A (84) A (84)-A (80) = -3 (8484) - (8080) = 0.00000003

4. Observe the known points coordinates on the same triangle point, and add the second new correction to DX, DY, DZ according to the observation results.At this time, use the GPS positioning instrument to observe all the coordinates of all known points for the third correction until the coordinate value of the observation of the GPS receiver is close to the known point coordinates.The average value of the observation value of the point and the known coordinates is the final correction number of DX, DY, and DZ. The above operations generally circulate to the second time to get the ideal correction number.

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.
