Communication method for mobile terminal and power line carrier equipment

Abstract

The invention discloses a communication method for a mobile terminal and power line carrier equipment. According to the method, the mobile terminal, the power line carrier equipment and a power carrier adapter are arranged, wherein the power carrier adapter is connected with the mobile terminal and the power line carrier equipment and is connected with the mobile terminal by a universal serial bus (USB) data line; the power carrier adapter is connected with the power line carrier equipment by a power line and is used for receiving the data sent by the mobile terminal, processing the data and transmitting the processed data into the power line; the power line carrier equipment can be used for monitoring the signals on the power line and receiving data and can actively send data into the power line; the power carrier adapter is capable of monitoring the signals on the power line and receiving the data, and the processed data is transmitted into the mobile terminal. According to the communication method, the networking is convenient and flexible, installation and use are convenient, additional configuration is not needed, and the plug and play effect is achieved; a modularized design idea is adopted, the compatibility is good, the power line carrier equipment can be used in different places and can be matched with most mobile terminals on the market.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a communication method between a mobile terminal and a power line carrier device. Background technique [0002] Power line carrier communication (PLC) refers to the technology of high-speed transmission of analog or digital signals by means of carrier wave using existing power lines. The biggest feature is that there is no need to re-establish the network, as long as there are wires, data transmission can be carried out. [0003] The smart home system is attracting more and more people's attention. It forms a network of all household appliances, and users can control household appliances and obtain real-time status information through smart devices such as computers or mobile phones. [0004] The use of power line carrier technology to realize the interconnection of home equipment and mobile terminals has major advantages. It can not only use the existing wire ...

Problems solved by technology

[0005] The power carrier adapters currently on the market only provide data connection interfaces, and cannot directly convert the control commands of mobile terminals such as tablets into commands that smart appliances can recognize. If you want to directly control smart appliances through mobile terminals, you first need to build a complex The network supports data transmission, which virtually reduces the flexibility of the smart home system and increases the input cost.

[0006] Chinese patent 201210321480.2 discloses an adapter and a data transmission method applied to the adapter, which includes a downlink communication module connected to a smart substation device or an electric meter terminal, an uplink communication module connected to a management center, and an uplink communication module and a downlink communication module at the same time A microprocessor module connected to the module, the microprocessor module sends a communication instruction to the downlink communication module, receives the data of the substation equipment or the electric meter terminal obtained by the downlink communication module according to the communication instruction, and sends the received data to the uplink communication module, The received data is sent to the management center through the Ethernet interface of the uplink communication module. This method only solves the communication problem between the substation and the electric meter, and does not solve the problem of home equipment networking

[0007] Chinese patent 200610058877.1 discloses a network device suitable for a power line carrier communication system. This method uses power lines to transmit network signals, and does not effectively solve the problems of home networking and device matching.

[0008] So how to use the power line to realize the direct communication between the mobile terminal and the power line carrier device has not yet a clear solution
