[0011] Advantages:

[0012] 1. In the present utility model, an ultrasonic welding technique is used to fix the transparent plate to the face cover; it has a good dust-proof effect. When wiring the main control board, the protective cover is turned up, the limiting groove of the protective cover slides out of the limiting shaft and rotates along the center of the guiding shaft, and the main control wiring terminal is exposed for wiring. After the operation is completed, the limiting groove of the protective cover is pushed back into the limiting shaft to cover the wiring terminal, preventing the staff from accidentally touching the terminal and getting an electric shock; the guiding groove provided at the upper left corner of the main control board cooperates with the guiding boss of the bottom case to limit the direction of installing the main control board on the bottom case. This anti-fooling design is beneficial to production.

[0013] 2. In the present utility model, through the installation of the protective structure, it can effectively protect the controller during installation, thereby effectively improving the use effect of the controller for the monitoring system. Description of the Drawings
