Large-LCD touch-type programmable temperature controller

Abstract

The invention relates to a temperature controller, in particular to a large-LCD (Liquid Crystal Display) touch-type programmable temperature controller. The hardware structure of the large-LCD touch-type programmable temperature controller comprises an MCU (Microprogrammed Control Unit) main control circuit, wherein a power supply circuit and a keying circuit are connected to the MCU main controlcircuit, a crystal oscillator circuit and a man-machine display circuit are also connected to the MCU main control circuit and the MCU main control circuit is connected through connecting circuits ofan upper circuit board and a lower circuit board for controlling an output interface circuit. According to the invention, the need of current society for an environment-friendly and energy-saving temperature controller is met, potential safety hazards in the use of the temperature controller are lessened, the reliability of the temperature controller and a control system to which the temperature controller belongs is improved, a user can adjust needed parameters according to personal desires, user experiences are improved, and the requirement on a user for the individualized adjustment of a target temperature in practical applications is met.

Description

technical field [0001] The invention relates to the field of controllers, and in particular provides a large liquid crystal touch programmable temperature controller. Background technique [0002] Temperature controllers can be divided into three types: mechanical, electronic and intelligent. Mechanical temperature controllers have large temperature drift and inaccurate temperature control. Except for special applications, they are rarely used at present. The temperature control performance of the electronic thermostat has been greatly improved compared with the mechanical one, but there are many problems such as poor anti-interference ability, low reliability, and low security, which make it more and more difficult to meet the needs of current social development. A trend of being gradually eliminated. Intelligent thermostats not only have the advantages of precise temperature control, perfect functions, high integration, and good reliability, but also greatly improve the e...

AI Technical Summary

Problems solved by technology

[0008] The present invention aims at the above deficiencies, and provides a large liquid crystal touch programmable temperature controller, which solves the current society's requirements for green energy saving, reduces the potential safety hazards in the use of the temperature controller, and improves the temperature controller itself and its performance. The reliability of the control system realizes the target parameters required by the user to adjust according to their own wishes, increases the user experience, and meets the needs of users to adjust the temperature individually in practical applications
