The temperature detection and control module detects the indoor temperature in real time, carries out inquiring and displaying of temperature setting and heat energy consumption, and transmits temperature data detected in real time to the wireless communication module; the wireless communication module outputs the temperature data detected in real time to the fuzzy controller module and transmits heat data stored in a fuzzy controller to the temperature detection and control module; the fuzzy controller module calculates according to input indoor actual temperature signals by means of the fuzzy control algorithm, outputs output valve opening signals to the motor driving valve module, drives a motor to operate, and controls valve opening of a radiating device; the flow measurement module is used for measuring heat consumption values and outputting the heat values to the fuzzy controller module.

Description

technical field [0001] The invention belongs to the field of heat control and metering systems, in particular to a wireless temperature control system for heat metering based on a fuzzy control algorithm. Background technique [0002] Heat energy meters are generally used to measure the energy consumption of user systems, and are widely used in northern heating and thermal energy systems. However, the existing heat meters can only measure the heat, but cannot realize the automatic control of the indoor temperature to achieve the constant temperature required by the user. Therefore, temperature controllers play a very important role in heating heat metering systems. [0003] In the early stage of temperature controller development, it was a mechanical temperature controller. This type of temperature controller used a bimetallic sheet or an inflatable bellows to sense the indoor temperature, and used a band switch to directly adjust the wind speed. The bimetal temperature co...

Problems solved by technology

The conventional PID control algorithm can achieve better control effect on most temperature control systems, and its control performance is superior to the fixed value switch temperature control method, but it has obvious disadvantages, such as relying on the object model, for nonlinear, large lag , time-varying system control effect is not ideal, etc.

Although most of the current temperature control methods have been able to cope with the ubiquitous control requirements in reality, there are still some unresolved problems, such as high power consumption, single heat measurement and control methods, single function, low accuracy, and poor installation. Convenience, etc.
