Abstract

The invention discloses an extreme low-power high voltage switch board wireless temperature measurement transmitting-receiving sub-node system. The system is composed of a contact temperature sensor, a transmitting-receiving chip, two AA batteries and a control center. The control center employs a one-chip microcomputer MSP 430, and at normal time, the control center is in a sleep mode, and when the setting time arrives, the control center is transferred to a working mode. In the working mode, the control center completes instruction receiving, temperature data reading, data transmitting-receiving and communication protocol parsing and other functions. The contact temperature sensor completes the temperature transition function. The used transmitting-receiving chip is a LTP5901-IPM, which is based on a 6LoWPAN protocol, and the communication frequency range is 2.4, and the chip completes wireless data transmitting-receiving, self-organizing net, automatic sleeping, automatic route and automatic waking up and other functions with extreme low-power. After employing the technical scheme discloses in the invention, two AA batteries are used, thereby guarantying the normal working time can last for 80 months, and the best level is 24 months in the industry at present.

Description

technical field [0001] The invention belongs to the field of smart grid online monitoring and its application, in particular to a wireless temperature-measuring transceiver sub-node system for a high-voltage switch cabinet with extremely low power consumption. Background technique [0002] The high-voltage switchgear is an important equipment in the power system, and ensuring the safe operation of the high-voltage switchgear is an important basis for ensuring the safety of the power grid. During the long-term operation of the high-voltage switchgear, the contacts of the isolating switch and the connection of the bus bar will heat up due to aging or excessive contact resistance. The temperature of these heating parts often leads to equipment burnout and other accidents. The conventional manual inspection method cannot detect potential heating faults in the switchgear in time, let alone judge the fault development trend and locate the fault location. Aiming at the shortage of...
