Embodiment Construction

[0057] The communication interface between a detachable communication module and a network appliance provided by the first embodiment of the present invention will be described below. The communication interface includes a hardware connection method and a communication frame format for mutual communication. Each will be described below.

[0058] The communication interface is based on the universal asynchronous serial port (UART port) to realize the communication between the communication module and the network home appliances. Since the universal asynchronous serial port is widely supported by various home appliance control boards, this kind of communication interface is easy to obtain the support of network home appliances. On the basis of the universal asynchronous serial port, the communication interface further provides a more specific hardware connection method and a communication frame format suitable for completing the communication task between the network home appli...

Abstract

The invention discloses a communication interface of network household electrical appliance, wherein the communication interface is connected with network household electrical appliance and an independent communication module, the communication interface is connected via four lines, via asynchronous serial half-duplex communication to complete data communication, the connecting lines of four-line connection comprise a signal receiving line, signal sending line, an earth line, and a power line. The invention also discloses a relative communication method for transmitting control command from communication module to network household electrical appliance, comprising that (121), the communication module sends a control frame to the network household electrical appliance, (122), the communication module judges if receives a feedback frame of the network household electrical appliance, if receives, ending the communication, or not receives after waiting for preset maximum waiting time T1, entering into step (121). The invention also discloses a method for using network household electrical appliance to send report message to the communication module.

Description

technical field [0001] The invention relates to the field of household electrical appliances, in particular to a communication interface of a networked electrical appliance. The invention also provides a communication method for network home appliances. Background technique [0002] Network home appliances refer to electronic and electrical products used in home networks and similar places that have the characteristics of information interconnection, intercommunication or interoperability at the network level. The so-called home network refers to the integration of the control network and the multimedia information network, and realizes information equipment, communication equipment, entertainment equipment, household appliances, automation equipment, lighting equipment, security (monitoring) devices, and water, electricity, and heat meters within the family. (Three watches and three defenses), home help alarm, health care and other equipment interconnection, management and...
