[China Instrument Network Instrument Research and Development] On September 5, Tianjin Binhai Power Supply Company completed the installation and testing of an on-line manhole cover monitoring device independently developed at No. 02 Beichen Street Power Engineering Wells, marking the first manhole cover online monitoring device in Tianjin. Put into use.
With the rapid development of the Binhai New Area, the construction of cable-pipe wells is increasing day by day. The loss of manhole cover creates great difficulties for the daily operation and maintenance of cables. In the past, the manhole covers of electric power workers can only rely on regular inspections by personnel. However, manhole covers and power cables are lost from time to time, which adversely affects the property of enterprises and the safety of power facilities. At the same time, once the covers are lost, it will bring hidden dangers to people and vehicles. This has become a problem that Binhai Company urgently needs to solve.
Based on the "Dawn Innovation Studio", Binhai established a cable transport inspection team to combine daily operation and maintenance experience for three months to overcome technical difficulties in structural design, water and moisture resistance, battery attenuation, signal transmission, and cost of manufacturing. Independently developed and designed the first manhole cover online monitoring device in Tianjin. The principle of the device is to use the mechanical stroke change to determine whether the well cover is correctly installed. When the well cover is abnormally opened or shifted, the device will perform signal conversion, and the well cover Internet of Things attribute, status, power status, time data, etc., in the form of text messages Transmitted to the operator's mobile phone, the operating personnel to deal with this in a timely manner. The device only works when the well cover is opened abnormally, which greatly reduces power consumption. It can be used for at least 5 years and will effectively control the loss of manhole covers, greatly improving the efficiency and quality of operation and maintenance, and ensuring the safe operation of power facilities.
