An RFID-based cable head temperature monitoring and display device, system and method

Abstract

The present invention provides an RFID-based cable head temperature monitoring and display device, system and method. The device includes a main control system, an RFID data acquisition module, a radio frequency gain antenna, a plurality of RFID temperature monitoring modules, and devices connected to the main control system respectively. Power management module, network transmission module, LCD display module, local data transmission interface, local alarm module; the main control system and RFID data acquisition module are set at a position with a set distance from the RFID temperature monitoring module, and multiple RFID temperature monitoring modules are installed On the cable head of the substation, it is used to detect the real-time temperature signal of the cable head. The system of the present invention comprises the apparatus described above. The method of the present invention is applied to the system described above. The invention applies the Internet of Things to realize wireless network transmission, which can improve temperature measurement accuracy and real-time performance, and realize temperature monitoring of various cable heads in substations, thereby solving the problem of real-time monitoring of circuit equipment failures and accidents caused by high temperatures in substation cable heads. question.

Description

Technical field [0001] The present invention relates to the field of power devices, and in particular, to an RFID-based cable head temperature monitoring display device, a system, and a control method applied to the system. Background technique [0002] The power of electric equipment will directly affect its reliability. If it is not possible to discover and control, the excessive degree of overheating will have a large impact on the performance and equipment life of the insulation material. [0003] The existing substation cable connector temperature measuring device is realized using an infrared or infrared imaging method, and only the external exposed interface is performed, and the non-exposed contact point such as a cable plug and the plum contact can not be measured for effective temperature monitoring. [0004] The existing substation RFID cable connector temperature measurement device supports only other devices that will be transmitted to the gateway through wired netwo...
