Offline issues are a common problem with GPS positioner. If you do n’t know much about the positioning of the positioner, you may be anxious. The offline of the device means that normal work interruption will affect normal use. This must be handled as soon as possible. So how to deal with this situation? You can handle it according to several different situations:

　　1. GPS device is in the signal blind zone caused offline alarm

　　If the GPS positioner is in a blind spot in the signal, such as the vehicle in the underground parking lot, tunnels, remote rural areas, etc., the device cannot receive signals and will also trigger an offline alarm. If you receive an offline alarm notification, first judge whether it is offline caused by signal issues.

　　The offline alarm caused by this signal is common, and the platform cannot receive the information of the GPS positioner. This situation does not need to be too worried. Leaving the signal difference area, receiving the signal will return to normal.

　　2. SIM card problem leads to offline alarm

　　The GPS positioner works in a special environment, resulting in damage or deformation of the SIM card body. For example, some engineering vehicles work in high temperature environments. If the device card is an ordinary card, it is easy to deform and damage at high temperature. As a result, the SIM card is unable to work normally, and the equipment appears offline.

　　In case of poor contact or damage to the SIM card, professionals need to help check. If the card is damaged, let the manufacturer be installed again. If you are not a professional, don't change your card easily to avoid damage to the equipment.

　　3. The GPS positioner has no power to cause offline alarm caused

　　If the GPS positioner has no power supply, the device will also be offline. If it is a wired device, it may be caused by loosening the line, or the equipment is installed on a very electric circuit of the car. Since the equipment is installed in a very electric circuit, as the vehicle power failure equipment will not be able to power the power, the power outage alarm or insufficient power will occur. When the vehicle is started normally, the equipment will return to normal. This may be connected to a very electric circuit.
