The monitoring system of the nuclear, biological and chemical control center in the civil air defense command post is a facility and equipment specifically designed for nuclear, biological and chemical detection in civil air defense engineering, usually used to carry out nuclear, biological and chemical defense tasks. It can monitor and alert various substances, including air quality monitors (used to detect toxic substances in the air), poison detection alarms (used to detect biochemical weapon toxins), and radiation detectors (used to detect radioactive substances). Specifically, the air quality monitoring device in the fixed multifunctional nuclear, chemical, and biological control center can detect toxic and harmful gases such as carbon monoxide (CO), hydrogen sulfide (H2S), ammonia (NH3), and formaldehyde (HCHO) in the air, as well as the number of bacteria and viruses in the air, in order to evaluate whether the air quality meets safety standards. The toxic agent detection alarm can detect nerve agents, erosive agents, asphyxiating agents, etc. in biochemical weapons and issue corresponding alarm signals. A radioactive detector can detect the presence of radioactive substances in the environment, as well as the intensity and type of radioactive substances. 19 channels of display data are uploaded through the industrial bus, and the system adopts RS485 bus and touch screen design, with recording, display, control, alarm, historical query, curve display, and system expansion functions. The on-site testing probe, each indoor display, and its lower end probe form a subsystem, and their independent control units can ensure that the equipment in each small area can be reliably connected to the system. Dynamically display the operating status and parameters of each subsystem.
Functions of the monitoring system in the nuclear, chemical and biological control center of the multifunctional civil air defense command post:
1. Instrument access: Multiple air quality monitoring devices, multiple air radiation monitoring devices, toxic agent monitoring devices, and oral toxic agent alarms can be connected
2. Digital usage channels: 19 channels have been put into use and customized to display up to 100 channels according to demand.
3. Instrument display: touch screen
4. Built in functions: HMI display, recording, control, alarm, historical query, curve display.
5. System communication: using RS485 bus
6. System Scalability: The system has strong scalability: measuring points can be added arbitrarily within a certain range, and automatic measurement of on-site parameters can be achieved.
