Basic content of intelligent system for civil air defense engineering

The equipment in civil air defense engineering, including protective equipment, ventilation and air conditioning equipment, water supply and drainage equipment, power generation and distribution system equipment, etc., can be intelligently monitored and controlled to improve the operation and management level of the project, reduce the operation and maintenance costs during peacetime, and enhance the support, protection, and survival capabilities during wartime. The monitoring system for civil air defense engineering equipment mainly includes the following contents:

1) Monitoring of protective equipment. In civil air defense engineering, protective equipment mainly refers to protection

The explosion-proof button for the (sealed) door and related entry applications, as well as the three prevention alarm equipment for monitoring biochemical WQ and WQ attacks, although the content is not extensive, are very important equipment in civil air defense engineering.

1. Three proof alarm host. At present, the three defense alarm devices used in civil air defense engineering are mainly toxic agent alarms and radiation O

Police, this is the "eye" of civil defense engineering monitoring whether there are HWQ and biochemical WQ attacks. The selection of these devices themselves and their layout in the project are the content of the chemical defense profession, and will not be described here. Due to interface issues between the three prevention alarm host of the project and the equipment automation system.

The interface between the three prevention alarm host (toxic agent alarm and radiation alarm) and equipment automation is generally achieved through two methods:10 interface modes and host networking interface modes.

10 Interface Method: The three defense alarm host generally has alarm output contacts. Once an enemy related WQ attack is detected, the corresponding alarm contacts will be closed. The controller of the automation system automatically controls the three prevention status of the project by monitoring the status of these alarm output contacts. This method of interface is the most direct and simple, and is commonly used in engineering. Host networking method: The new three proof alarm host usually has RS232 or Ethernet networking function. For the three proof alarm host with RS232 interface, it can be connected to the control network of the automatic control system or directly connected to the host of the automatic control system through a protocol converter (if the distance between the two is within 15m); The three proof alarm host with Ethernet interface can be connected to the network through switches using Category 5 cables or optical fibers.

In addition to the physical connection requirements mentioned above, the network communication protocol must also be provided when supplying the three proof alarm host for software integration in the automation system. The advantage of this method is that it can provide more detailed information, such as accurately knowing which probe is triggering the alarm and the current dose when there are multiple toxic agent probes; The disadvantage is that for the current situation of civil air defense engineering, only the three defense alarm host is reserved during the construction of the project, and no equipment is installed. Without a unified and fixed communication protocol, it is difficult to achieve communication with the automation system if equipment is installed before the war.
