太阳能集热系统多通道水温检测装置的研究

水温是太阳能集热系统智能控制的核心信号源之一，其采集过程是太阳能集热系统控制的典型任务。针对当前水温检测采用两通道水温检测装置，由于通道太少，导致系统成本增加的问题，文中提出了研究多通道水温检测装置的方法，通过设计PIC单片机硬件电路、信号采集发送程序、仿真及调试，使多通道水温检测装置可根据用户需要采集多组水温数据，增强了太阳能集热系统的工程适应能力。

Research of the Multi-channel Water Temperature Test Devices in Solar Energy Collection System

The water temperature is one of the core signal source in the intelligent control system of solar collector, its collection process is a typical control task of solar collector system. For the current water temperature is detected by two-channel temperature detection device, the channels is too few, so it causes the system to the problem of increasing costs.This paper presents a study method of multi-channel temperature detection device, through the PIC microcontroller hardware circuit design, signal acquisition and output procedure design, simulation and debugging, the Multi-channel temperature detection device can achieve Multi-channel temperature data acquisition according to user needs, the ability to adapt project of solar collector system is enhanced.
