目的:建立一种方舱式机动医疗系统对大气环境中有毒有害生物、化学及放射性物质超压防护的技术体系。方法:按照监测预警、报警控制、滤毒净化、建立超压、超压监测5个控制环节进行设计,采用中央集中监测与报警控制、各分布式舱室终端同时动作响应的工作模式实现超压集体防护。结果:该防护系统能对大气环境中的有毒有害物质监测预警,能使单舱和系统各舱连接使用时分别建立并保持300 Pa和130 Pa以上的超压防护,并能实时监测各舱内的超压状态。结论:方舱式机动医疗系统的超压集体防护系统能对大气环境中的有毒有害物质实施有效防护。
OBJECTIVE: To establish a technical system for the over-pressure protection of poisonous pests, chemical and radioactive substances in the atmospheric environment by a cabin-type motorized medical system. Methods: In accordance with the monitoring and early warning, alarm control, drug purification, the establishment of overpressure, overpressure monitoring five control aspects of the design, the use of centralized monitoring and alarm control, distributed cabins at the same time the terminal response mode of operation to achieve overpressure collective Protection. Results: The protection system can monitor and pre-alarm the toxic and harmful substances in the atmospheric environment, and can establish and maintain overpressure protection of 300 Pa and 130 Pa respectively when the single-cabin and the system are connected with each other, and can monitor the inside of each cabin in real time Overpressure state. Conclusion: The overpressure collective protection system of the cabin-type motorized medical system can effectively protect the toxic and harmful substances in the atmosphere.
