2、 Main functions of the system

A.Humanized service
1. Adopting a voice reporting system: Before the operator enters the work area, the system automatically reports the environmental conditions of the work area through manual voice and allows the operator to enter the work area after 15 minutes of ventilation under safe conditions.
2. Adopting advanced touch sensitive ten inch color large screen in China: real-time display of various parameters and system status, large and clear display words, easy and simple operation.
3. Adopting human recognition technology: The screen automatically lights up when the operator enters the recognition range. After the operator stops operating, the system automatically turns off the backlight to save energy.
4. Adopt a self strengthening tracking algorithm for suspicious detection nodes, and operators can also adjust the system inspection interval according to actual needs.
5. Designed with a wide working power supply of 85-265V, it also has surge and lightning protection functions. Capable of adapting to various harsh environments;
6. The over limit alarm adopts multiple methods such as voice, flute sound, and alarm light.
