Problems that may occur when using 4g gps tracker from yilian's blog

1. Confuse the vehicle trajectory and observe the vehicle trajectory. The analysis of vehicle driving habit is one of the important means to predict vehicle risk. But when air controllers see a vehicle's trajectory ignoring the terrain, it can certainly affect their mood. The reasons for this situation are generally as follows: first, the vehicle is installed with signal blocker, resulting in unstable signal receiving equipment; Second, when the vehicle passes through some areas with poor GPRS signal such as tunnels, high-rise buildings and airports, the update of location information is unstable.

2, overdue vehicle escape, positioning display but can not find the mortgage vehicle, this is usually due to: first, the risk control personnel of the vehicle loan company is not familiar with the geographical environment of the vehicle, unable to quickly locate the vehicle through the location information; Second, due to the poor signal environment of the vehicle position and the poor location of the base station, there is a large gap between the actual position of the vehicle and the displayed position of the platform.

3. The positions of the two GPS in the same model are very different for three reasons:

(1) The two devices installed by the vehicle are different from the wired device and the wireless device, with different location information (non-real-time positioning of the wireless device).

(2) When the platform inputs the device information, the two devices are registered on different vehicles (which happens very rarely).

(3) The following are the top causes of concern for air controllers: equipment is removed, vehicles are removed, resulting in inaccurate location information.

4. Please manually restart the 4g gps tracker. During the use of the 4G GPS tracker, problems such as offline device, inaccurate positioning, and track drift will inevitably occur. These problems can be basically solved by sending device upgrade instructions, assisting positioning of the base station, and restarting the device. The most pointless car loan company is one such "device reboot", for example: A car loan company: How can my device display offline? Customer service: OK, just a moment, please. This device needs to be manually restarted before it can come online. Auto loan Company: Are you kidding? The device is installed on a mortgaged vehicle. Where do you want me to find it to restart? !

5. Removal of the GPS device is usually a precursor to fraud/secondary charges, and the vehicle owner may remove the vehicle GPS device in advance to avoid tracking. To prevent this, air controllers will install two or more GPS devices in a vehicle, and wired devices should be used in conjunction with wireless devices to improve monitoring efficiency. In fact, there are usually symptoms before the device is removed, that is, the vehicle will stay in an auto 4S shop, an auto repair shop, a used car lot, etc. All of these can be tracked.
