Abstract
A high voltage node wireless temperature measurement alarm system comprises a wireless temperature sensor, a data processing information gatherer, a data transmitter and cells, wherein cells are connected with the information gatherer and simultaneously connected with the data transmitter; the information gatherer is connected with the temperature sensor so as to supply power for the temperature sensor and simultaneously read temperature values; and the information gatherer is also connected with the data transmitter so as to control the operation of the data transmitter for data transmission. Processed data received by the system provided by the invention can be used to provide decision layers with most direct and reliable data, so as to eliminate hidden troubles and minimize accidents to the maximum. If it is found by the system that a point temperature exceeds preset alarm limit, an audio alarm tone sounds and the position of a fault point is displaced so as to prompt related personnel to make corresponding emergency measures.
