Controller, the disconnecting link arm and shaft junction are additionally provided with diverting switch, and institute's controller connects the temperature sensor, described
Diverting switch；
The temperature signal of acquisition is sent to the controller by the temperature sensor, is previously stored in the controller
Temperature threshold data, when the temperature signal for judging the temperature sensor acquisition is more than the threshold data, described point of control
Stream switch is closed.
Further, wireless communication module, remote terminal are further included, the controller is connected by the wireless communication module
Connect the remote terminal；The controller sends out the temperature signal that the temperature sensor gathers by the wireless communication module
Remote terminal is sent to be stored.
Further, the remote terminal is additionally operable to send remote control signal to the controller, and the controller is also
For controlling being opened or closed for the diverting switch according to the remote control signal.
Further, the controller chip is TMS320C54X chips.
The embodiment of the present invention is connect by detecting the more serious disconnecting link shaft junction of heating position and disconnecting link both ends with contact
The temperature of proximate is touched, when judging that temperature is too high, disconnecting link arm and the diverting switch of shaft junction are arranged on by control
Contact resistance is reduced, it is serious so as to solve the problems, such as to generate heat.
