Wireless energy transmission, communication and networking system based on coil

Abstract

The invention discloses a wireless energy transmission, communication and networking system based on a coil, which relates to the technical field of electronic communication and comprises a main station module and a relay module, the main station module comprises a first coil, and the relay module comprises a second coil. The main station module is installed on a test device, and the relay moduleis installed on a tested device. The test device transmits energy and communicates with the tested device through the main station module. The tested device communicates with the test device through the relay module; the master station module sends the energy and information of the test device to the relay module through the first coil, and receives the information sent to the test device by the tested device through the first coil; and the relay module receives the energy and information of the test device through the second coil, and sends the information sent to the test device by the tested device to the main station module through the second coil. The wireless energy transmission, communication and networking system based on the coil disclosed by the invention can meet the use requirements of non-contact energy transfer and communication.

Description

technical field [0001] The invention relates to the technical field of electronic communication, in particular to a coil-based wireless energy transmission, communication and networking system. Background technique [0002] At present, in the fields of ships, military industry, automotive electronics, industrial automation, and home appliances, the master and slave machines (that is, the central controller and the controlled equipment) are connected in a wired manner. Wired communication methods based on independent wires, such as CAN bus, LIN bus, I2C bus, Ethernet and RS485 bus, etc. need power lines and communication lines to work; methods based on wireless communication such as WIFI, Bluetooth, zigbee, etc. also need power lines to work ; Although the battery can also be used to replace the power cord based on wireless communication, the battery has a shelf life and needs to be replaced regularly. When replacing, it needs to be slotted on the device, which has a great im...

AI Technical Summary

Problems solved by technology

Wired communication methods based on independent wires, such as CAN bus, LIN bus, I2C bus, Ethernet and RS485 bus, etc. need power lines and communication lines to work; methods based on wireless communication such as WIFI, Bluetooth, zigbee, etc. also need power lines to work ;Although the battery can also be used to replace the power cord based on wireless communication, but the battery has a shelf life and needs to be replaced regularly. When replacing, it needs to be slotted on the device, which has a great impact on airtightness and water resistance

However, in some special fields such as military industry and ships, there is relative movement between the energy or signal sending end (such as test equipment) and the receiving end (such as the device under test), and even strict requirements for airtightness and water resistance. Based on wired method cannot meet the requirements

Therefore, the existing connection method has the following disadvantages: (1) the more nodes in the communication (i.e. the equipment or parts to be controlled or tested), the longer the wires for carrying communication signals, and the more complicated the line structure; (2) ) The number of transceiver chips is large, and the application cost is high; (3) It cannot meet the needs of non-contact energy transmission and communication
