摘　　要：介绍了基于MSP430F169混合数字信号处理器和EPM1270T144C5N复杂可编程逻辑器件(CPLD)而设计的综合报警平台系统。MSP430F169混合信号处理器具有超低功耗、处理能力强、系统工作稳定等优点。EPM1270T144C5N是一种具有144只管脚的复杂可编程逻辑数字器件,可以实现同时对多个不同的设备报警信息采集与处理。该综合报警平台对HIRFL-CSR上运行的各个分散的监测报警系统所产生的报警信息进行综合收集处理与报警,主要是先根据现有已上传到监测报警系统服务器中的原始数据进行条件判断,服务器根据判断结果发送相应的指令,MSP430利用UART功能和网络协议转换器配合接收;然后MSP430把接收到的指令数据解析后送到CPLD数据端口,由CPLD控制连接的报警器,实现报警功能;也可利用CPLD多管脚的优势,控制其他的现场设备。MSP430F169内部的12位ADC和DAC模块可实现对现场设备的模拟信号的给定和回读。系统客户端的软件采用Microsoft Visual C++6.0设计。该综合报警平台具有结构简单、响应速度快、稳定性好等优点,可实现单板对多种不同设备的控制与监测。A system of a comprehensive alarming platform based on MSP430F169（a mixed signal microcontroller） and EPM1270T144C5N（a complex programmable logic device-CPLD） has been introduced in this paper.The system has the advantages of ultra-low power consumption, powerful processing ability and operating stably by using the MSP430F169. Meanwhile the EPM1270T144C5 N is one of the complex programmable logic device which has 144 pins, and it was controlled by MSP430 to output or input the digital signals. The control system is charge for responding the alarming information from the scattered monitoring system which has running on the HIRFL-CSR. The duty of this system is to receive the commands which have been analyzed by server. The12-bit ADC and DAC module in the MSP430F169 can also read back the voltage of device or set the voltage to the specific device. The system＇s client software is designed in the Microsoft Visual C＋＋ 6.0 environment. The system has the advantage of a simple structure, fast response, good stability, and is able to monitor different running systems and devices in real time on one board.
