Boiler heating intelligent control system and method based on internet of things

Abstract

The invention provides a boiler heating intelligent control system and method based on internet of things. The boiler heating intelligent control system comprises an internet of things remote monitoring terminal, a remote network communication connection device and a boiler control system. According to the boiler heating intelligent control system, an advanced internet of things mobile terminal is combined with a PLC industrial automatic technique, remote communication ability is achieved, and boilers in different places can be monitored uniformly. When no person is on site, the operation states of the boilers can be monitored in real time through the internet of things remote monitoring terminal, and production efficiency and safety of the boilers are improved; the operation state of a heating system is monitored through a man-machine interface colored touch screen, and automatic fault emergent processing capacity integrating interlocking and warning is achieved; a fuzzy self-adaptation PID controller is guided according to outdoor temperature, water return temperature and other actual work conditions, optimal frequency control is carried out on fire grate rotation speed, rotation speeds of a water feeding pump and a make-up pump and rotation speeds of an air blower and an induced draft fan, and the boiler heating system can operate intelligently, efficiently, stably and reliably.

Description

technical field [0001] The invention belongs to the field of boiler heating, in particular to an intelligent control system and method for boiler heating based on the Internet of Things. Background technique [0002] With the continuous improvement of living standards, people's requirements for the quality of heating in urban life are also getting higher and higher. At present, the use of boiler heating in winter still occupies a dominant position in northern my country, but the configuration of the control systems in most boiler rooms is relatively backward, and the frequency conversion speed regulation of fans, circulating pump motors and water pump motors still stays at PID. In the stage of the control mode, it is not possible to optimize the control of each frequency conversion device and realize the optimization of the motor running speed, so that the purpose of real-time and stable control of the water temperature cannot be achieved. [0003] In addition, most of the s...

At present, the use of boiler heating in winter still occupies a dominant position in northern my country, but the configuration of the control systems in most boiler rooms is relatively backward, and the frequency conversion speed regulation of fans, circulating pump motors and water pump motors still stays at PID. In the stage of the control mode, it is not possible to optimize the control of each frequency conversion device and realize the optimization of the running speed of the motor, so that the purpose of real-time and stable control of the water temperature cannot be achieved.

[0003] In addition, most of the monitoring of boiler room safety only stays at the on-site stage, and the operation status information cannot be communicated between boiler rooms, and it is impossible to find solutions and preventive measures in time according to the failure of boilers in different places, so as to improve safety performance
