Problems solved by technology

[0002] In recent years, underground cables in urban transmission networks have gradually replaced overhead lines, and their operation safety has received widespread attention. Excessive temperature of cable conductors will cause accelerated aging of insulating materials, affect the safety of cables, and shorten the service life of cables. At present, they are mainly buried inside cables. The temperature detector is used to directly monitor the temperature of the conductor. This method may damage the insulation layer of the cable and bring safety hazards. At the same time, the cable laid underground will cause problems such as inconvenient laying and complex structure.

Abstract

The invention discloses a wireless monitoring method for trench power cable temperature. The method comprises the following steps: in step A, temperature data is obtained after periodic measurement of electric cable surface temperature is realized via a temperature sensing node through a temperature sensor on a electric cable surface; in step B, the data in step A is transmitted via a ZigBee network and finally gathered to a gateway node; in step C, a GPRS DTU device is connected with the gateway node in step B, a definite IP address is obtained, and the GPRS DTU device which serves as a client end of a transmission control protocol TCP is remotely connected with a monitoring center host computer; in step D, data processing operation is performed via a server and a PC, and a whole system is controlled; according to the wireless monitoring method disclosed in the invention, an original electric cable detection and transmission method is changed, and wireless detection of electric cable temperature can be realized; accurate measurement, structure flexibility and easy-to-expand property can be realized.

Description

technical field [0001] The invention relates to a power system, in particular to a method for wirelessly monitoring the temperature of a grooved power cable. Background technique [0002] In recent years, underground cables in urban transmission networks have gradually replaced overhead lines, and their operation safety has received widespread attention. Excessive temperature of cable conductors will cause accelerated aging of insulating materials, affect the safety of cables, and shorten the service life of cables. At present, they are mainly buried inside cables. The temperature detector is used to directly monitor the temperature of the conductor. This method may damage the insulation layer of the cable and bring safety hazards. At the same time, the cable laid underground will cause problems such as inconvenient laying and complicated structure. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a wireless tempe...
