摘　　要：为适应多道放射性活度采集系统小型化需求,设计了基于Modbus的多道放射性活度采集模块。该模块信号处理前端采用隔离和外部计数技术,用一个微处理器读取各通道的数字信号,再分别与电脑和触摸屏通信,便于电脑或仪器单独操控。该模块可同时对各通道状态、数据等信息实时传输,还可实现多个模块间的联机通讯。利用该模块,仪器开发成本低、容易实现、抗干扰性强。In order to adapt to the miniaturization requirements of multi-channel activity acquisition system,a multichannel activity activity acquisition module based on Modbus was designed. The signal processing front-end of this module adopts isolation and external counting technology. It uses a microprocessor to read the digital signals of each channel,and then communicates with the computer and the touch screen separately,so that the computer or the instrument can be controlled independently. This module can accurately transmit the status of each channel,data and other information at the same time,and can also realize the online communication between multiple modules. Using this module,the instrument development cost is low,easy to implement,and strong anti-interference.
