摘　　要：在核电厂通风系统原有模拟温度控制器的基础上,针对温度控制器接口固定,参数预先设置以及多种输出方式的特点,设计一种以"前端输入调理模块+多通道ADC+STM32"架构为核心的数字化多功能温度控制电路。介绍电路的硬件结构和软件设计流程,阐述采样数据处理,模拟相切电压输出以及控制原理,并给出部分软件编程的设置。试验结果表明,该温度控制器能够实现对通风系统温度的稳定可靠控制和测量温度及参数的数字化显示,可以完全替代模拟温度控制器。Based on full study on the original analog temperature controller of ventilation system in nuclear power plant, for the interface definition fixation, parameters preset as well as multiple output combination of the temperature controller circuit, a digital temperature circuit based on the front-end input conditioning module ＋ multi channel ADC＋STM32 architecture is proposed. The hardware structure and software process are described in details. The sampling data processing, phase-cut voltage output as well as control principle are focused, and some part of software program is presented. The experimental results show that the temperature controller can stably and reliably control the temperature of ventilation system and display digital parameters, and it can completely replace and upgrade the original analog controller.
