【摘要】：目前,中国北方冬季取暖仍以集中供暖为主,由于大多数地区家庭没有安装分户热量控制装置,因而存在严重的热量浪费和不必要的资源消耗及过多的环境污染等附加效应。针对这一现象,本文提出了一种应用电热型流量阀进行流量调节的户端温度智能控制系统的设计理念,应用智能供暖系统户端温度控制器解决北方专区冬季供暖时的热量浪费问题。使用本文所研发的户端温度控制器,用户可自行根据需要设定家中温度控制程序,不仅可保证居住环境温度舒适,还能节省供热热量且针对本文户端温度智能控制系统专用的户端温度控制器测试系统可对控制器产品进行出厂前的实际测试运行和分析。文章首先介绍了供暖温度控制器发展现状,在此基础上介绍了智能供暖系统户端温度控制器工艺要求、基本构成和功能；本文选定STC12C5A60S2单片机为控制器CPU,完成控制器串口模块、时钟模块、存储器模块、温度传感器模块、执行器模块的硬件电路设计,采用2.4英寸TFT触摸屏作为控制器的人机交互界面；根据控制器工艺要求,完成了主程序、串口通信程序、显示存储程序、触摸按键程序、PID算法程序的软件编写。在此基础上,设计完成控制器PCB板的设计与产品样机制作,并应用力控组态软件研发了户端温度智能控制器的测试系统。在实验室完成了控制器功能测试,.结果证明了控制器基本实现了工艺要求,PID控制算法在此系统应用中具有准确性。
[Abstract]:At present, central heating is still the main heating system in northern China in winter. Because the household heat control device is not installed in most areas, there are serious heat waste, unnecessary resource consumption and excessive environmental pollution. In view of this phenomenon, this paper puts forward a design concept of indoor temperature intelligent control system, which uses electric heat flow valve to adjust flow rate. The indoor temperature controller of intelligent heating system is used to solve the problem of heat waste in winter heating in northern region. Using the household temperature controller developed in this paper, the user can set up the home temperature control program according to the need, which can not only guarantee the comfortable living environment, It can also save heat and heat, and the test system of indoor temperature controller for the intelligent control system of household temperature can be used to test and analyze the controller products before they leave the factory. This paper first introduces the current situation of heating temperature controller, and then introduces the process requirements, basic structure and function of the intelligent heating system's indoor temperature controller, and selects STC12C5A60S2 as the controller CPU to complete the serial port module of the controller. The hardware circuit of clock module, memory module, temperature sensor module and actuator module is designed. The 2.4-inch TFT touch screen is used as the man-machine interface of the controller. Serial communication program, display storage program, touch key program pid algorithm software programming. On this basis, the PCB board of the controller and the prototype of the product are designed and completed, and the testing system of the intelligent controller is developed by using the force control configuration software. The controller function test was completed in the laboratory. The results show that the pid control algorithm is accurate in the application of this system.
