Anti-theft alarm system for field power supply cables or optical fiber cables and monitor method thereof

Abstract

The invention discloses an anti-theft alarm system for field power supply cables or optical fiber cables and a monitor method thereof. The anti-theft alarm system comprises wireless anti-theft triggers and a short message alarm, wherein each wireless anti-theft trigger comprises a guarder processor, a sensor trigger unit, a guarder wireless control unit, an electric quantity detection unit and a guarder radio-frequency unit; and the short message alarm comprises an interface unit, an alarm processor, an alarm wireless control unit, a GSM module, an alarm radio-frequency unit and an alarm power supply. The monitor method utilizes the wireless interaction between the wireless anti-theft triggers distributed on the cables and the short message alarm mounted indoors to form a wireless link and realize wireless chain-type monitor alarm. If a thief acts to trigger a wireless anti-theft trigger, the module sends out a theft state to the accessory short message alarm in a wireless mode, and the short message alarm sends out theft information to the user. The invention has the advantages of low energy consumption, low cost, far transmission distance and convenient mounting and is suitable for the theft resistance of the field power supply cables or optical fiber cables.

Description

technical field [0001] The invention relates to the technical field of field power supply cables or optical fiber cables anti-theft technology, in particular to an anti-theft alarm system for field power supply cables or optical fiber cables and a monitoring method thereof. Background technique [0002] At present, the theft of power supply cables is frequent, causing huge economic losses every year. The distribution of power supply cables is wide, and it is difficult to prevent theft through traditional supervision methods. There is an urgent need for innovative technology products to achieve effective anti-theft. [0003] Anti-theft products for field power supply cables can be roughly divided into two types, one uses a GSM module (Global Mobile Communication Module) plus a sensor solution, and the wireless communication part uses a GSM module to send a text message to the user to alarm; one uses a high-power radio plus For the sensor solution, the wireless communication ...

AI Technical Summary

Problems solved by technology

However, since power supply cables such as mobile base stations in the wild are mostly distributed in mountainous areas, the monitors work in open-air environments such as wilderness and mountains, and need to have the characteristics of working for a long time only relying on battery power, so there are more requirements for the product, such as Low power consumption, high concealment

Due to the high power consumption and large volume of GSM modules and high-power radio solutions, it is difficult to meet the above requirements

Especially for buried wiring type power supply cables, it is not applicable

[0004] Due to the high cost of GSM modules and high-power radios, it is not suitable for dense installation, and it also affects the monitoring effect of the entire line

There may be situations such as monitoring blind spots and inaccurate positioning

Assuming that one is installed every 200 meters, then the middle section of 200 meters may not be monitored, and the positioning distance cannot be accurate within 200 meters

[0005] In addition, in the wild, especially in mountainous areas, due to the limitation of terrain, the transmission effect and distance of GSM module and high-power radio may be affected
