When this server fails, switch control The unit control is switched to another server to ensure the smooth progress of the work. When the two servers are working, the data interaction is carried out in time to avoid data loss; When the limit switch is activated, the processor will send a remote alarm through the wireless communication module after obtaining the information, and control the sound and light alarm module to send an on-site alarm. The temperature and humidity sensor can obtain the temperature and humidity information. If the temperature and humidity are abnormal, the processor will also carry out Alarm, if the temperature is too high, the processor controls the fan to work to cool down; the chip IC1 uses NE555, and the chip IC2 cd4017; there is a storage module, which can store the time and times of switching between the two servers, and can also store temperature and humidity information. The voice module can imitate the voice of a person, and it also has a deterrent effect on the personnel who try to open the upper cover. It can be seen that the present invention has outstanding substantive features and significant progress compared with the prior art, and the beneficial effects of its implementation are also obvious of.
