Communication control device and method for multi-connected equipment and multi-connected device

Abstract

The invention discloses a communication control device and method of multi-connection equipment and multi-connection equipment. The device includes: a wireless communication module, a wired communication module and a control unit, which can share the same CAN serial port communication; the wireless communication module and the wired communication module The communication module can share the same communication link; the control unit is configured to determine the communication environment of the multi-connected device; and, if the communication environment is a wired communication environment, control the communication switch to turn on the wired communication module and turn off Turn on the wireless communication module to realize data transparent transmission through the wired communication module; if the communication environment is a wireless communication environment, then control the communication switch to connect the wireless communication module and disconnect the wired communication module to realize data transparent transmission through the wireless communication module. This scheme reduces the communication difficulty of multi-connected devices by adopting a communication control scheme in which wired communication and wireless communication are combined and transmission protocols are compatible with each other.

Description

technical field [0001] The present invention belongs to the technical field of communication, and in particular relates to a communication control device and method for multi-connection equipment and multi-connection equipment (such as a multi-connection system), in particular to a multi-connection communication control compatible with CAN communication and wifi-mesh communication Apparatus, method and multi-connection device (eg multi-connection system). Background technique [0002] In related solutions, multi-connected devices (such as multi-connected air conditioners, etc.) use CAN (Controller Area Network, controller area network) bus, 485 bus and other technologies to communicate, but multi-connected devices use bus communication technology, which requires the multi-connected It is difficult to operate the wiring operation of the unit of the conventional equipment. [0003] The above content is only used to assist in understanding the technical solution of the present...
