化工泄漏智能检测及无线传输系统的研究

对化工气体泄漏智能检测和报警系统进行了研究,该系统由底层、中间层和上层三层模块组成,底层上连有NO2和NH3等气体传感器,通过模糊控制器对传感器的信息进行模糊化、推理和判断,一旦发生泄漏则向中间层通过短途无线的方式传输数据;然后中间层通过长途无线的方式向顶层传送数据.在底层模块上,安装有用于定时记录现场数据的“黑匣子”,供发生泄漏后的原因查找用;每隔一定时间整个系统将进行自检,一旦发现问题则向顶层进行报警;上层模块与计算机具有通讯接口.实际使用表明该系统的泄漏报警率达到100%.

Research on intellectual test of chemical gas leak and alarm system

The intellectual test on the chemical gas leak and alarm system is researched. It is made up of three modules, bottom flow, middle flow and upper flow. There are some gas sensors of No2 and NH3. Once the leak occurs, these sensors will transmit data to the middle flow by way of short distance radio signal. The middle flow will transmit data to upper flow by way of long distance radio signal. There is a timing-recorder, black box, which records the data, in order to find the reason of leak, then does self-test regularly, and alarms to the upper flow.
