On-line monitoring control system and method for external environment of civil air defense door

Abstract

The invention relates to an on-line monitoring control system and method for external environment of a civil air defense door. The on-line monitoring control system and method are used for an electriccivil air defense door. The system comprises a sensor module, a processor, an upper computer and a driving module, wherein the sensor module is used for acquiring environmental information outside the civil air defense door; the processor is used for acquiring the civil air defense door outside environmental information collected by the sensor module, processing the environmental information intoto-be-compared information and transmitting the information to the upper computer; the upper computer is used for acquiring the to-be-compared information and comparing the to-be-compared informationwith a preset value; the driving module is used for driving an actuator of the electric civil air defense door to further control opening and closing of the electric civil air defense door; the uppercomputer sends a door opening instruction to the processor when judging that the to-be-compared information is lower than the preset value, and the processor controls the driving module to drive theactuator of the civil air defense door to act to open the civil air defense door. The environmental safety situation outside the door can be known accurately in real time, and the civil air defense door is opened automatically after environmental safety is confirmed, so that potential threat is reduced, and safety is improved.

Description

technical field [0001] The invention belongs to the field of civil air defense doors, and in particular relates to an online monitoring and control system for the external environment of a civil air defense door. Background technique [0002] The civil air defense door is a door with protective effect when entering the area with protective measures in the event of war, earthquake and other natural disasters or other emergencies. It is mostly used at the entrances and exits of underground shopping malls, tunnels, and underground rail transit such as subways. [0003] From a functional point of view, the design of civil air defense doors is mainly based on a single protection and barrier function, which is a relatively traditional design with a single function. However, with the further improvement of informatization conditions and social needs, the traditional design of civil air defense doors can no longer be used. Meet actual needs. After the air defense door is closed, th...

AI Technical Summary

Problems solved by technology

[0004] When the civil air defense door is closed, the civil air defense door and the passage (semi-open type) of the open environment form a relatively closed environment, and the air flow velocity is extremely slow (the pressure gradient between the passage and the external environment is small, and there is almost no convection), which is very unfavorable to the air defense system. The diffusion of pollutants (such as toxic and harmful gases) in the area, the air quality in the passage of the civil air defense door and the air quality in the external open environment have certain differences. If the timing of opening the civil air defense door is determined according to the environmental quality standards in the external open environment, It may cause potential harm to the life forms in the protective space
