Remote alarming device for limit-exceeding temperature of hand bearing

The invention provides a remote alarming device for limit-exceeding temperature of a hand bearing, and aims at effectively reducing the labor intensity of repair people and adaptively monitoring the temperature change of the hand bearing. According to the technical scheme, the device comprises a main controller, a temperature detecting module, a touch screen and a power module, wherein an I/ O port of the main controller is connected with the temperature detecting module; the temperature detecting module is connected with a temperature sensor through a signal wire; the main controller is connected with the touch screen through a communication cable; the power module is connected with the I/ O port, the temperature detection module and the touch screen. With the adoption of the device, the repair time can be greatly reduced; people at the site can view the display value of the monitoring device in a vehicle room and then determine the device state; therefore, the manpower is saved, and the possibility of missing in traditional manual inspection manner can be avoided.
