Moreover, the alarm module uses a buzzer for sound alarm.

Advantage and positive effect of the present invention are:

1. The single-chip microcomputer of the present invention and the background host computer communicate through wireless signals based on IEEE802.11, so as to reduce the disadvantages of cable clutter caused by traditional network cable communication. A wireless sensor unit is installed in each cabinet, which can monitor the physical environment information of the cabinet, including real-time temperature, humidity, power status, and equipment operation status in the cabinet. The back-end host computer manages the data of multiple wireless sensor units in a graphical manner at the same time, and monitors the physical environment in all cabinets in the entire computer room.

2. The present invention only requires the management personnel to set the temperature, humidity, power supply status, and equipment operating status thresholds in the normal state of the physical environment of the cabinet in advance in the background host computer. When the system is running, the system receives data from the wireless sensor unit in the cabinet in real time. Monitor the data and display the monitored data in real time in a graphical way. When the monitored data exceeds the preset threshold in the system, the alarm module will immediately give a sound alarm, and at the same time it will be displayed on the LED connected to the background host computer. The number, location and fault attribute of the faulty cabinet are displayed on the screen, which is convenient for the management personnel to carry out timely and rapid maintenance.

3. The present invention can effectively improve the management efficiency of the physical environment of the information cabinet of the smart grid, and the management personnel of the computer room can monitor the physical environment status of each cabinet in the computer room in real time, and it is convenient and beautiful, high in safety, and easy to implement.
