Split networked intelligent temperature controller of central air conditioner

Abstract

The invention discloses a split networked intelligent temperature controller of a central air conditioner. The temperature controller comprises a control panel and a power supply board which are connected; the control panel comprises a temperature measurement module, a liquid crystal display module and a parameter setting module; and the power supply board comprises a power supply module, a relaycontrol module and an RS485 interface circuit, wherein the power supply module supplies power to the relay control module and the control panel. A single micro control unit (MCU) structure is adoptedin the temperature controller, and the front panel and the rear panel are split in the design; and by adopting the single MCU, the defect that a wiring tube of the traditional temperature controller is not easily connected to centralized (remote) monitoring of the central air conditioner is overcome, the dependency of civil engineering is reduced, the use safety is promoted, the universal applicability of any standard junction box is enhanced, and the networked expansibility of the system is exploited.

Description

technical field [0001] The invention relates to a split-type network intelligent temperature controller for a central air conditioner. Background technique [0002] The central air-conditioning terminal thermostat is the actuator for adjusting the room ambient temperature of the entire building air-conditioning system. It is generally divided into air control, water control, or both air and water control. No matter which control mode is adopted, the ultimate goal is to keep the ambient temperature of the room constant at the set temperature, so as to achieve comfort and energy saving effects. The controller structure is generally composed of a temperature sensor, LCD display, parameter setting buttons, relays, etc., and is an integral on-site controller. [0003] With the demand for information fusion and energy saving and emission reduction, thermostat manufacturers have begun to pay attention to the network control technology of the controller. The communication networks ...

AI Technical Summary

Problems solved by technology

[0010]1) The central air-conditioning main unit can only communicate with the rear panel (executive drive mechanism), and it is not possible to connect multiple central air-conditioning main units in the entire building with all fan coil units and terminal temperature control units. Devices form a large network;

[0011]2) This kind of thermostat adopts dual MCU, which is a split design in name, but the cost is high and it is not easy to promote

The manual only functionally explains part of the external physical structure, and it can be known through analysis: 1) If this patent realizes no polarity, then it is necessary to design a polarity automatic detection and inversion circuit; 2) If it is necessary to realize control signal transmission, then It can be further divided into the following two situations: if wired: the control signal must be modulated, then superimposed on the two power lines, and the control signal is demodulated and processed on the driver board; if wireless: a simple Wireless remote control circuit, etc., but the wireless signal has to pass through the wall, etc., the effect is affected

Therefore, the simplicity of wiring will inevitably lead to the complexity of the original circuit processing.

Through its patent specification, it is impossible to see its specific realization, which has no reference value for this design

At the same time, through the introduction in the patent specification, it is known that it does not contain network communication functions, cannot realize the Dalian network of central air-conditioning, and has high cost and limited practical value
