Description
TECHNICAL FIELD
[0001] The utility model relates to power equipment auxiliary tool technical field, especially a kind of alarm fence with identification function and fence device. BACKGROUND
[0002] In the mode known to the inventor, many power equipment (such as transformer, distribution room, etc.) in the transformer substation have very high voltage near them. In order to ensure personnel safety and avoid electric shock accidents, safety fences need to be installed around these devices. Safety fences are provided with warning signs "Stop, high voltage danger!" to warn unrelated personnel from approaching power facilities. The warning signs are installed in fixed positions, and there are visual blind spots. Unrelated personnel may not be able to see the warning signs. Especially in bad weather conditions such as heavy rain and heavy fog, the warning signs on the fence may become unclear, reducing the warning effect. Therefore, the warning effect of the warning signs is limited.
[0003] Further, in some embodiments, an infrared detector is installed on the safety fence. The infrared detector is connected to an alarm system. When a person is too close to the safety fence, the infrared detector sends an electrical signal to the controller, and the controller controls the alarm to sound an alarm, reminding the person to stay away from the safety fence. However, although the alarm can be sounded for personnel approaching the fence, it cannot distinguish between maintenance personnel and unrelated personnel. Therefore, when maintenance personnel approach the fence to maintain the power equipment, the alarm device will give a false alarm. Moreover, the use of infrared detectors is susceptible to environmental temperature and heat sources, and has poor anti-interference ability. SUMMARY

[0029] The human body detector 6 is a microwave detector, which works based on the Doppler principle and is used to detect whether a person is too close to the first fence 1. Specifically, the microwave detector emits electromagnetic waves, which are absorbed or reflected when encountering a human body. The reflected echo will change the signal received by the receiving antenna.
