技术领域 FIELD

[0001] 本发明属于环保监测领域,具体涉及一种自适应无线中继气体检测报警系统及布设方法。 [0001] The present invention belongs to the field of environmental monitoring, particularly relates to an adaptive radio relay system and a gas detection method for laying.

背景技术 Background technique

[0002] 随着经济的快速发展与生活质量的提高,人们对大气环境中有毒有害气体含量的越来越关注,同时在工业生产过程以及危化品仓储环境中,及时发现可燃及有毒有害气体的泄漏,能够有效的规避安全隐患,从而保障现场工作人员的人身及财产安全。 [0002] With the rapid economic development and improve the quality of life, people on the atmosphere of toxic and hazardous gas content of growing concern, while industrial production processes and storage of hazardous chemicals in the environment, the timely detection of flammable and toxic gases the leak, can effectively circumvent the security risks in order to protect personal and property safety of field staff.

[0003]目前,广泛应用于工业环境的气体检测系统及设备分为两类,第一类是便携式气体检测仪,这类气体检测仪可以随身携带,当工作人员进入作业环境时,如果检测到可燃或有毒有害气体泄露,设备会及时报警,提醒工作人员尽快撤离。 [0003] At present, widely used in industrial environments and gas detection system equipment is divided into two categories, the first category is a portable gas detector, such gas detector can carry, when the staff into the working environment, if it is detected flammable or toxic gas leak, the device will give an alarm to alert staff to evacuate as soon as possible. 但是,这类气体检测仪不适用于需要24小时不间断监测的工作环境,对于一些危险区域,往往需要首先确定环境安全,才允许工作人员进入,此类气体检测仪同样不适用。 However, this type of gas detector does not apply to require 24-hour monitoring of the work environment, for some dangerous areas, often need to first determine environmental safety before allowing workers to enter, such a gas detector the same does not apply. 第二类是在线式气体检测仪,在线式气体检测仪采用固定安装的方式,在检测区域内根据检测仪的有效检测范围合理分布检测点,多个在线式气体检测仪实时将检测到的环境气体示值上传至气体报警控制器,可以实现检测区域的24小时不间断无人监测。 The second category is the online gas detector, gas detector line by way of fixedly mounted within a reasonable distribution of the detection region of the detection point based on the effective detection range of the detector, a plurality of gas detector-line in real time the detected environment gas gas alarm indication uploaded to the controller, 24-hour unattended monitoring detection region can be achieved.
