Air conditioner networking control device based on wireless network

Abstract

The invention provides an air conditioner networking control device based on a wireless network, and relates to the field of control over air conditioner networking. The air conditioner networking control device based on the wireless network is composed of an instruction issue device, an indoor control center and a device receiving sub system. The instruction issue device is an electronic device which sends data information through the wireless network. The indoor control center comprises a master control chip, a radio frequency module and a GPRS module. The device receiving sub system comprises a master control chip, a radio frequency module, a Flash storage module and an infrared receiving and dispatching module. According to the control device, under the condition that the machines and circuits of an original air conditioner are not changed, all air conditioners of a family form a control local area network, the instruction issue device controls the air conditioners in the local area network of the family, communication between the device receiving sub system and the air conditioners is achieved through an infrared emitting circuit coming with the device, normal control can be achieved without modification of the machines and circuits of the original air conditioners, and the normal use of original remote controllers coming with the air conditioners is not affected. The device does not need to be replaced when different brands of air conditioners are replaced.

Description

technical field [0001] The invention relates to the field of air conditioner control, especially the field of air conditioner network control. Background technique [0002] Although air-conditioning equipment has been popularized, most of this type of equipment adopts the infrared remote control method. Infrared transmission requires that there should be no light-blocking obstacles between the control and the receiver and the transmission distance is limited. Therefore, this method is limited by the control distance and control direction. In the room, it cannot be controlled remotely, nor can it realize intelligent control. [0003] At present, there are some remote air-conditioning control devices on the market, which usually use wired network or combined with WiFi to form a control network, and some use the SMS function of mobile phone to realize remote control, but these control methods require the transformation of the control circuit of the controlled air conditioner. ...

AI Technical Summary

Problems solved by technology

The cost of wired network is high, and there are many restricted conditions (the control device in the controlled room should always be kept online). WiFi technology has the problems of high cost and low security, and it also requires wired network access

These remote air-conditioning control devices generally simply increase the remote control distance, and must require indoor wired network support, which is not suitable for low-cost home operation requirements
