基于RS-485总线的双G-M计数管γ剂量率探测器研制

Development of γ Dose-rate Detector with Two G-M Counter Tubes Based on RS-485 Bus

根据放射性场所工作人员辐射防护需求,设计了γ剂量率探测器。介绍了探测器硬件电路及软件设计,利用双G-M计数管覆盖高低量程范围,采用RS-485通信接口,可连接最多128个节点,具有远程传输能力,适用于多点分布式实时监测。探测器结构紧凑,功耗低,抗干扰能力强,工作稳定可靠。

The γ dose-rate detector is designed to meet the requirement of radiation protection for people who work in radioactive environment.Two G-M counter tubes are used to cover wide range.The detector has RS-485 communication interface and the signal can be transmitted with long distance.The maximum number of detectors connected with the system is 128.The detector can be used for distributed and real time multi-site monitoring.The detector has compact structure,low power-consume,better anti-interference ability and high reliability.
