The vehicle GPS tracker, as its name implies, is a kind of positioning terminal device used in vehicle trajectory inquiry. It is different from the navigation system of the vehicle. The navigation system in the car can tell you how to go, but the vehicle GPS tracker, by means of server and platform,which can query the location information of the vehicle, the vehicle fault query and so on. In the application field, the vehicle GPS tracker is mainly used for the management of enterprise vehicles, the management of insurance rental vehicles, etc., to prevent the phenomenon of private use of the bus.

After constantly understanding the vehicle GPS tracker products, we often encounter some problems, we will answer the problems encountered in the use of the vehicle GPS tracker:

1. After my vehicle is equipped with the vehicle GPS tracker, what is displayed on the platform map is not the location of the vehicle?


A. There are usually several reasons for this.


First, just after installing the vehicle GPS tracker, and the vehicle is in a static state, the device will not transmit new location information like that server, so the old positioning data is displayed. Just let the car go out for a few minutes to update the location information.


Second, the signal conditions of the environment in which the vehicle is located are relatively poor, and the GPS satellite signal cannot be completely searched, resulting in the vehicle tracker not receiving the signal. It is recommended to detect whether it is caused by a signal problem and to eliminate related problems.


Third, the vehicle GPS tracker installation problem, the installation location is too closed, it is not easy to search for satellite signals again after the satellite signal is interrupted. If this problem occurs multiple times, it is recommended to adjust the installation location.


Fourth, check if the SIM card is working properly.

2. After the remote positioning of the fuel through the GPS positioning terminal platform, why can the vehicle still drive spontaneously?


A: Please make sure that the vehicle GPS tracker is wired correctly. In addition, the vehicle GPS tracker must be connected to the server to ensure that the vehicle is in a "stationary" or "driving" state, and the vehicle speed is less than 20 kilometers. If the tracker is offline, not positioned, or the vehicle speed is higher than 20 kilometers per hour, the tracker will not cut off the oil even if the remote power cut is successful.

3.Send a mobile phone command to the vehicle GPS tracker, why there is no reply or reply error


A: This happens in general with SIM cards and signals. You can check the status of the SIM card:

First, dial the number on the SIM card of the vehicle tracker to see if it is owed


Second, check whether the SIM card has a GPRS traffic plan and SMS service.


Third, the signal is poor in the area, and the SMS gateway is delayed.

4. Why does the data in the running statistics not match the actual situation?


A: The running statistics function on the monitoring platform is based on the location information uploaded by the vehicle GPS tracker to the monitoring platform. The location information of the vehicle GPS tracker may be limited by factors such as signal, environment, and fault. In other words, if the vehicle GPS tracker is offline or not located, and there is no accurate position data, the data of the running statistics may automatically retransmit some data, but this will have some errors with the actual route. Therefore, the operational statistics on the monitoring platform can only be used as a reference.


5.The vehicle's trajectory is not correct, the drift is very serious?


A: This problem is usually caused by poor satellite signals.

First, when our vehicles are driving or stopping, they usually encounter tunnels, high-rise buildings, or places with more trees. In this case, the GPS signal will be weaker and even completely shielded, and the equipment will not receive the signal. There will be a phenomenon of inaccurate positioning.


Second, when the GPS signal of the device is interfered or the signal is blocked, the device will automatically switch to base station positioning or WIFI positioning according to the strength of the surrounding signal source. When the peripheral base station signal is strong, the device will automatically connect to the base station for positioning.
