Description

A kind of temperature controller control circuit for heating system

Technical field

The utility model relates to a kind of control circuit based on wireless communication module, specifically, is a kind of temperature controller control circuit for heating system.

Background technology

In existing heating system, usually adopt heating installation valve and gauge tap to form, change the valve opening of heating installation valve by the gear of rotary control switch, reach the purpose of regulating indoor temperature.

Its defective is: existing gauge tap is fixed on the wall usually, adopt wired mode to link to each other with heating installation valve in the heating system, in gauge tap intrinsic gear is set, realize adjustment by changing gear, the system intelligent degree is not high first, and mode of operation is too single; Second installation and maintenance inconvenience, equipment break down and are easy to generate the trouble of checking circuit, and movability is not strong, uses extremely inconvenience.

The utility model content

In order to address the above problem, the utility model proposes a kind of temperature controller control circuit for heating system, improve the movability of control end by adopting radio communication, and this circuit has the multi-mode working effect, reach the purpose of Based Intelligent Control.

The technical solution adopted in the utility model is as follows:

A kind of temperature controller control circuit for heating system, comprise power module and microcontroller, its key is: be connected with RF wireless communication module, display module, hummer, temperature sensor and key-press module on the described microcontroller, microcontroller detects indoor temperature information by temperature sensor, can the initialization system running parameter by key-press module, can be to the control information of temperature-sensing valve wireless transmission by the RF wireless communication module, described temperature information and system operational parameters may be displayed on the display module.

Further describe, described key-press module is combined by a plurality of free-standing button keys, comprises that on/off button, pattern switching button, parameter arrange button, raise button, down button and ACK button.。

As preferably, described display module is the LCD LCDs.

Remarkable result of the present utility model is: circuit structure is simple, convenient and practical, realize that by adopting wireless communication module the signal between temperature controller and the heating valve transmits, utilize microcontroller to make up a micro control system, in microcontroller, set multiple mode of operation, detect indoor temperature in real time by temperature sensor, the final purpose that realizes Based Intelligent Control, equipment mobility is strong, and intelligent high, installation and maintenance is also very convenient.
