Many users in the logistics industry always encounter various problems in the process of using 3g tracker. Today we will discuss about the normal installed 3g tracker. What are the common problems encountered during the usage phase?
Question 1: The previous vehicle was determined to be fine, but the next day I found that the 3g tracker became offline. And this car is not used by outsiders, but driven by an old driver of the company. Logically, there will not be any strange problems. Why is the 3g tracker offline?
Answer: When the GPS is offline, it has already indicated that the GPS is not working or has not entered the working state. Why is the GPS offline? First of all, whether the data card has expired and needs to be renewed. Secondly, we need to check whether the device is connected to the normal power line of the vehicle. If the locator is not connected to the normal power line, the device may not work normally due to a power failure after the vehicle is turned off. Another common situation is that when the car drives into the underground garage, due to the weak signal, the data connection between the device and the platform cannot be performed offline.
Question 2: In the process of replaying the target vehicle's trajectory, it is found that the target vehicle is sometimes normal and sometimes disconnected, or the driving route becomes a straight line.
Answer: This kind of situation must be checked from the installation, especially when the 3g tracker is in the metal shell or the upper layer of the device is metal, the 3g tracker will not be positioned. The principle is that the metal will reflect GPS signals and communication. Signal. Secondly, the installation point of the 3g tracker is close to the engine, and it is in a state of high temperature and humidity for a long time, and the GPS automatically enters a stop sleep state and cannot be online.
