技术领域 TECHNICAL 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, in particular to an adaptive wireless relay gas detection alarm system and laying methods.

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 of people on the atmospheric environment of toxic and hazardous gas content of growing concern, while the industrial production process and storage of hazardous chemicals in the environment, the timely detection of combustible and toxic gases 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 gas detection systems and environmental equipment is divided into two categories, the first category is a portable gas detector, such gas detector can carry when entering the working environment of staff, if it is detected flammable or toxic gas leaks, timely warning device 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, such a gas detector does not apply to 24-hour monitoring of the work environment, for some hazardous area, often need to first determine the 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 on-line gas detector, gas detector line installation fixed manner within a reasonable distribution of the detection area detection point detector according to the effective detection range, a plurality of on-line real-time gas detector will detect the environment gas indication uploaded to the gas alarm controller, can achieve 24-hour unmanned surveillance and testing area.

[0004] 在线式气体检测报警系统的信号传输分为有线传输和无线传输两种,有线传输采用4-20mA电流信号或者RS485数字信号。 [0004] signal transmission line gas detection and alarm system is divided into two kinds of wired transmission and wireless transmission, cable transmission using 4-20mA current signal or RS485 digital signal. 近年来,随着物联网技术的发展,采用无线组网形式的气体检测报警系统越来越受到人们的关注,但是还未能得到行业内的广泛应用。 In recent years, with the development of networking technology, the use of wireless networking in the form of gas detection and alarm system, more and more people's attention, but has not been widely used within the industry. 已有的气体检测报警系统主要存在以下方面的问题有待解决: Existing gas detection and alarm system is mainly the following aspects of the problems to be resolved:

[0006] 2、常规有线电缆信号(4-20mA电流信号或者RS485数字信号)传输距离较短,一般不超过1000米,对于更远距离传输需要采用光纤链路,增加了系统搭建的复杂度。 [0006] 2, a conventional wired cable signal (4-20mA current signal or RS485 digital signal) transmission distance is shorter, usually not more than 1000 meters, the need to adopt a more long-distance transmission fiber link, increasing the complexity of the system built.

[0007] 3、常规无线气体检测报警系统,信号传输距离及可靠性受环境因素影响较大,比如报警控制器与气体检测仪传输路径上存在较大的金属板墙或者大功率用电设备的电磁干扰时,将严重影响无线通信质量,甚至造成无法通信。 [0007] 3, a conventional wireless gas detection alarm system, the signal transmission distance and reliability influenced by environmental factors, such as large metal sheet wall or high-power electrical devices present on the controller and the gas detector alarm transmission path electromagnetic interference, it will seriously affect the quality of wireless communication, or even result can not communicate.
