An input end of the fire-fighting electromagnetic valve is connected with an output end of the temperature controller in the fireproof control cabinet through an intermediate relay. The temperature controller compares the temperature measured by the temperature measurement module with a preset temperature through a comparator circuit, and when the temperature measured by the temperature measurement module exceeds the preset temperature, the fire-fighting electromagnetic valve is controlled to be opened to spray and cool the activated carbon adsorption box.

Each intelligent control cabinet can independently monitor the real-time temperature inside the activated carbon adsorption box and determine the switching of the fire sprinkler system based on the detected temperature, displaying the real-time temperature on the control cabinet panel. The intelligent control cabinet accurately captures the real-time temperature inside the activated carbon adsorption box using a resistance temperature probe and transmits the data to the intelligent temperature controller. The controller determines the operating status of the fire sprinkler system based on the captured temperature and the operating conditions set by the technicians. This distributed intelligent control cabinet system allows for one-to-one real-time monitoring of the temperature of each activated carbon adsorption box, enabling timely and effective activation of the fire sprinkler system, thus effectively protecting the safety of the activated carbon adsorption boxes and ensuring the safe operation of customer equipment and property.

[0030] AC power L supplies power to the temperature controller. A thermistor for temperature sensing is connected to the input terminal of the temperature controller. The controller's switch signal output terminal is connected to the lower terminal of a three-position selector switch. When the three-position selector switch is in manual mode, AC power L is connected to intermediate relay K1. When the three-position selector switch is in automatic mode, AC power L outputs switch signals NO1 and NO2 from the temperature controller and is connected to intermediate relay K1. The normally open contact of intermediate relay K1 controls the opening and closing of the fire solenoid valve.

[0031] As an optional implementation, it also includes: an indicator light connected in parallel across the intermediate relay.
