TECHNICAL FIELD
[0001] The utility model relates to fire alarm technical field, concretely is a gas fire extinguishing controller display module circuit. BACKGROUND
[0002] The gas fire extinguishing controller is an important part of modern fire protection system, which is specially designed for efficient and rapid fire fighting in specific places. Through the integration of advanced sensor technology and control logic, the device can monitor the fire risk in the environment in real time, and automatically or manually start the gas fire extinguishing system after confirming the fire to suppress or extinguish the initial fire. The gas fire extinguishing controller is divided into control part, display part and power supply part, and the display part is divided into state indicator light and 30 seconds countdown display. The state indicator light of the gas fire extinguishing controller plays a crucial role in the fire protection system, which indicates the current state of the system and possible problems through different colors and flashing modes. After receiving the fire signal, the gas fire extinguishing controller will start a countdown program. The countdown is usually set to 30 seconds (the time can be set between 0-30s according to actual needs), which is to give the on-site personnel a time to evacuate and prepare. The countdown display function will clearly display the remaining time on the display screen of the controller, so that the on-site personnel can intuitively understand how much time they can escape or take other necessary protective measures. The gas fire extinguishing controller is usually installed in the control room or designated safety area for easy monitoring and management by operators.

When processing a large amount of data or performing complex tasks, performance bottlenecks may occur. This will cause the system response speed to slow down, the processing time to be prolonged, and the multi-task processing capability to be insufficient. When running multiple applications or processes simultaneously, a single CPU may need to frequently switch tasks and allocate processing time, which will reduce the processing efficiency of each task and cause stuttering or delay.
