If the operating power of the host is set to be the preset maximum power, under the condition that the opening and closing angle of the valve and the air door also reaches the extreme value angle under the maximum operating power, the current smoke concentration of the floor where the terminal is located is not in the preset concentration range, an alarm trigger signal is generated to send the alarm trigger signal to alarm equipment, and maintenance personnel maintain the central purification system according to an alarm prompt sent by the alarm equipment.

Generally, in order to save electric energy, when a terminal machine is not started up on each floor, a host is in a standby state, and if the terminal machine is started up for use, the host is in a working state, specifically, a power switch key is further included on a control panel; the control panel is also used for receiving a key signal of a power switch key and sending the starting information corresponding to the key signal to the host through the main control module so that the host receives the starting information and enters a working state.
