Product functions and features
Shock wave signal detection: high-frequency dynamic pressure detector, high frequency response, fast speed, accurate detection of shock wave signal generated by explosion. | Flame signal detection: multi-band spectral detection, using imported photosensitive tubes and military manufacturing quality, to ensure that the flame sensor accurately detects flame signals. |
Visualized centralized control: Based on the visual comprehensive display, through accurate detection of fire data, equipment status display, equipment failure and other diagnostic analysis, intelligent early warning, troubleshooting and other automatic control are realized. | Accurate analysis and reliable execution: The sensor transmits the detected fire signal to the controller, and the controller reliably drives the action of the explosion suppressor through precise algorithms and accurate logic analysis and judgment. |
Multi-channel linkage control: The system can be connected to up to 10 flame sensors and shock wave sensors, and can be driven at the same time to achieve fire extinguishing and explosion suppression control of multiple pipelines. | Intelligent system operation and maintenance monitoring: Visualized monitoring technology is used to intuitively and comprehensively monitor the fire situation of gas transmission pipelines, comprehensively analyze and evaluate subsystems at all levels of explosion suppression, explosion arrest and explosion venting, and dynamically analyze the safety situation. |
