How to judge the alarm equipment and the reason after receiving the alarm information

1.GPS equipment is located in the signal blind area, causing off-line alarm.

If the GPS locator is located in the signal blind area, such as cars in underground garages, tunnels, outer suburbs and other areas with weak signals, the failure of mechanical equipment to receive signals will also trigger off-line alarm. If an off-line alarm notice is received, firstly, it is judged whether the off-line is caused by a signal problem.

Offline alarm caused by this kind of signal is very common, and the platform cannot receive the information of GPS locator. Don't worry too much about this situation. Leave the area with poor signal and return to the position where you can receive the signal.

2. The offline alarm is caused by the problem of 2. SIM card.

If the GPS locator is in a specific working environment, the SIM card will be damaged or deformed. For example, some construction machinery working in high temperature environment, if the IOT card in mechanical equipment is ordinary plastic card, it is easy to be deformed and damaged at high temperature. So the card will not work normally, and the machinery and equipment will go offline.

In case of poor contact or card damage, it should be checked by a professional. If the card body is damaged, let the manufacturer reinstall it. If you are a non-professional, don't change the card easily to avoid damaging the machinery and equipment.

3.3 Off-line alarm caused by power shortage. GPS locator.

If the GPS locator is out of power, it will also cause the machine and equipment to go offline. If it is a wireless device, it may be caused by loose lines. Or an unusual circuit for installing equipment for a car. Because the equipment is installed in an abnormal circuit, in the case of power failure of the car, the machine and equipment will not be able to supply power normally, thus causing power failure alarm or power shortage. When the car was running normally, the machinery and equipment were restored. This possibility is connected to a special circuit.

If it is a wireless device, check whether the battery of the machine device is not enough to cause offline. If the battery is dead, charge it.

4. The machinery and equipment are due or in arrears.

If the SIM card of GPS positioning expires, or it is in arrears, or the traffic package changes, it will also lead to the offline of machinery and equipment. In this case, it is usually to communicate with the supplier and ask whether the after-sales downtime is overdue, or the traffic tariff package has changed and the traffic cannot be used. If it is arrears, the recharge payment can be reused.

The above are several cases of off-line alarm of GPS equipment, and the actual off-line reasons need to be analyzed and checked in combination with the actual situation.
