Low-voltage telegraph pole stay cable pre-tightening force remote monitoring system of power line carrier technology

Abstract

The invention discloses a low-voltage telegraph pole stay cable pre-tightening force remote monitoring system of a power line carrier technology. A remote monitoring device comprises a tension sensor used for detecting the pre-tightening force of a stay cable, an idler wheel used for adjusting the pre-tightening force of the stay cable, a power line carrier module used for transmitting a signal through a power line carrier, an integrated controller used for collecting a tension signal of each low-voltage telegraph pole stay cable and conveying a control order and a monitoring center used for achieving remote detection. The stay cable is connected with the idler wheel. A rotary shaft of the idler wheel is connected with an output shaft of a stepping motor in a linked mode. The tension sensor is connected with the power line carrier module. The power line carrier module is in communicating connection with the integrated controller. The integrated controller is in communicating connection with the monitoring center. The monitoring center comprises a real-time monitoring module and a pre-tightening force adjusting control module. The low-voltage telegraph pole stay cable pre-tightening force remote monitoring system of the power line carrier technology can achieve on-line monitoring, reduce labor intensity and improve reliability.

Description

technical field [0001] The invention relates to a low-voltage transmission line utility pole monitoring system. Background technique [0002] Potential safety hazards of low-voltage power lines and utility poles have not received due attention. According to incomplete statistics, incidents of collapse of low-voltage transmission line utility poles have occurred frequently across the country. At about 9:00 am on April 27, 2012, at Yuntong 101 terminus at the north exit of Wangjing Guangshun South Street, Chaoyang District, Beijing, a utility pole near the platform suddenly collapsed, causing a pedestrian to injure their feet; December 19, 2012 in Tangxia Town, Dongguan City A utility pole collapsed at an intersection in , causing a massive traffic jam. While the Guanshi reporter was interviewing on the spot, he witnessed another electric pole falling down, which happened to hit a passing taxi. At 10:30 p.m. on January 28, 2013 in Nanjing, a No. 76 bus was driving to the Xia...
