针对温度监控的高精度、高可靠性的需要,基于LabVIEW的温控系统以STC12C5A60S2单片机和继电器组成硬件核心,选用PT100和DS18B20作为温度传感器,以LabVIEW为软件开发平台,通过wifi模块实现LabVIEW与单片机相互通信,达到了温度实时采集和控制的效果,同时利用Labsql工具可访问数据库的特点,将采集到的温度数据储存进Access数据库,使之同时具备查阅和删除等功能。此外为增强系统的安全性,根据基于LabVIEW的温控系统的特性,而设计出一款用户登录管理界面。
According to the need of high precision and high reliability of temperature monitoring, the temperature control system based on LabVIEW is composed of STC12C5A60S2 microcontroller and relay, PT100 and DS18B20 are selected as temperature sensors, LabVIEW is the software development platform, and LabVIEW and MCU Communicate with each other and achieve the effect of real-time temperature collection and control. At the same time, using the features of the Labsql tool to access the database, the collected temperature data is stored in the Access database, so that it also has the functions of viewing and deleting. In addition to enhance system security, based on the characteristics of LabVIEW-based temperature control system, and design a user login management interface.
