Wireless monitoring system for foundation stability of power transmission tower in goaf

Abstract

The invention relates to a wireless monitoring system for foundation stability of a power transmission tower in a goaf. According to the technical scheme, the input ends 6a, 6b, 6c, 6d and 6e of an RS485 transmitting and receiving module (6) are correspondingly connected with the output ends Va, Vb, Vc, Vd and Ve of five inclination sensors (1, 2, 3, 4 and 5); pins of a single-chip microcomputer (7) are correspondingly connected with the RS485 transmitting and receiving module (6), a state selection and code shifting switch (8), a GPRS (general packet radio service) data transmission unit (10), a serial clock chip (11), an EEPROM (electrically erasable programmable read-only memory) storage chip (12), a hardware watchdog chip (13) and a battery electric quantity monitoring module (14); the input end of the battery electric quantity monitoring module (14) is connected with the output end of a solar power supply system (15); the GPRS data transmission unit (10) communicates with an industrial computer (9) of a monitoring center through a wireless network. The wireless monitoring system has the advantages of high precision and high interference resistance and can stably work for a long time under a severe outdoor environment in which no power supply is provided and no worker monitors.

Description

technical field [0001] The invention belongs to the technical field of wireless monitoring. In particular, it relates to a wireless monitoring system for the foundation stability of a power transmission tower in a goaf. Background technique [0002] In recent years, with the continuous development of my country's electric power industry, a large-scale high-voltage transmission network has gradually formed. While the capacity of the power system has continued to increase, it has also greatly increased the requirements for monitoring and inspection of power equipment during the operation of the power grid. workload. In terms of power equipment monitoring, to ensure the safe operation of power transmission lines, routine inspections are generally required twice a month. Since the distribution points of power equipment are scattered and there are not many devices at each point, the real-time monitoring of these devices has always had the problems of high cost of laying lines an...
