Wireless control method and wireless network system of air conditioner

Abstract

The invention discloses a wireless control method and a wireless network system of an air conditioner. The method comprises the steps: a remote control device sends a remote control command to an indoor unit through a scheduled wireless network communication protocol, wherein the remote control command carries identification of the indoor unit required to be controlled remotely; and at least one indoor unit receives the remote control command, wherein each indoor unit confirms whether own identification of the indoor unit is identical to the identification of the indoor unit required to be controlled remotely and carried by the remote control command or not after receiving the remote control command, and generates control information for controlling an outdoor unit and sends the control information to the outdoor unit according to the remote control command under the condition that a confirmed result is yes. The remote control information of an air conditioning device is transmitted by building a wireless network, and the remote control command can be accurately and rapidly transmitted in a range covered by the network, thereby reducing interference received in the transmission process, avoiding limitation in distance, direction and routing and facilitating remote operation of users.

Description

technical field [0001] The present invention relates to the field of household appliances, and in particular, relates to a wireless control method for an air conditioner and a wireless network system for the air conditioner. Background technique [0002] Generally, air conditioners need to be equipped with remote control equipment, and the remote control equipment needs to communicate with the controlled air conditioner. [0003] At present, the communication technologies commonly used in air-conditioning systems mainly include wired communication between the internal unit and the wire controller, and infrared wireless remote control between the internal unit and the remote control. [0004] For a large-scale central air-conditioning system, using wired communication requires a very long communication line to connect the external unit and the internal unit of the air conditioner. Since the communication line itself has parasitic capacitance and resistance, the length of the ...

Problems solved by technology

[0004] For a large-scale central air-conditioning system, using wired communication requires a very long communication line to connect the external unit and the internal unit of the air conditioner. Since the communication line itself has parasitic capacitance and resistance, the length of the communication line will make this interference more obvious. It creates a lot of interference, and the wired connection itself is easy to introduce strong external signals to cause interference, and the connecting line is not easy to install; in addition, due to the distance limitation of the communication line of the wired controller, it will make the wired controller The installation position of the device is limited and it is not convenient to use

[0005] On the other hand, if infrared remote control is used, when sending remote control instructions, the remote control must be pointed at the infrared receiving head of the internal unit, which has limitations in direction, and the maximum remote control distance is generally less than 10m, so there is Defects with small control range

[0006] It can be seen that no matter which solution is used for remote control of air-conditioning equipment, there is a problem of inconvenient use, and no effective solution has been proposed so far
