Household appliance, independent communication module, communication method and control system

Abstract

The invention discloses a communication method of a household appliance master control module and an independent communication module, wherein the household electric appliance master control module and the independent communication module are connected through a communication interface. The communication method comprises the following steps: transmitting a control instruction to the household appliance master control module by the independent communication module according to a preset period, and alternately receiving feedback information of the household appliance master control module; recording information reception / transmission time by the independent communication module; if the information reception / transmission information achieves a total reception / transmission time threshold and the independent communication module does not receive response information fed back by the household appliance master control module, judging that the communication is abnormal by the independent communication module; and stopping sending the control instruction by the independent communication module and stopping communicating with the household appliance master control module. According to the communication method of the household appliance master control module and the independent communication module, the communication jamming of household appliances can be avoided and the communication is more stable. The invention also discloses a household appliance, the independent communication module and a control system of the household appliance.

Description

technical field [0001] The invention relates to the technical field of electrical appliances, in particular to a communication method between a main control module of a household appliance and an independent communication module, a household appliance, an independent communication module, and a control system for the household appliance. Background technique [0002] With the continuous popularization of household electrical equipment, more and more smart home appliances have entered the homes of ordinary people, helping people to deal with various aspects of life such as food, clothing, housing and transportation more conveniently and efficiently. With the development of the Internet, especially the Internet of Things, it will be a general trend for household appliances to be connected to communication networks via network relay devices such as wireless routers. Only in this way can people understand the status of home appliances and perform remote control no matter when an...

Problems solved by technology

However, when using the above method, since the length of the data frame to be sent varies, the sending time is not fixed. Obviously, if figure 1 As shown, in the case that there is a problem in the sending process and the waiting state cannot be entered, the subsequent step of resending cannot be entered, which causes the communication to be permanently suspended, that is, the problem of communication card dead
