摘要
分析可燃气体报警控制装置的工作原理。分析电磁干扰的三要素,重点分析干扰源。提出在硬件、软件及结构设计上进行控制装置的改进和完善,大大提高控制装置的抗干扰能力。通过试验室模拟进行电磁兼容试验验证,结果表明,该可燃气体报警控制装置的抗干扰设计符合国家标准GB 16808-2008《可燃气体报警控制器》中的要求,完全能满足复杂现场工作的需要。
The working principle of combustible gas alarm control device was analyzed. The 3 factors of electromagnetic interference were analyzed, and the interference source was focused on. The control device was improved in hardware, software and structure design. The anti-interference capability of the control device was greatly improved. By electromagnetic compatibility test verification in lab, the anti-interference design of the combustible gas alarm control device was proved to meet the national standard re- quirements of GB16808-2008 combustible gas alarm controller and can fully meet the needs of the complex work site.
