Non-contact power supply electricity pick-up device having real-time communication function

Abstract

The invention relates to a non-contact power supply electricity pick-up device having a real-time communication function, includes a non-contact power supply module, a magnetic guiding module, a carrier communication module and an upper control system, and can be applied to an AGV / EMS. The non-contact power supply module adopts a flat plate type structure, electromagnetic induction occurs between an upper coil of the non-contact power supply module and a non-contact power supply cable loaded with high frequency sinusoidal alternating current, and direct current of constant voltage is output after electric energy conversion; the magnetic guiding module detects a magnetic field generated by the non-contact power supply cable, makes a judgment and generates a guiding deviation signal; the carrier communication module adopts a binary system frequency-shift keying modulation mode, and generates a 2FSK signal with continuous phases; a noncoherent demodulation mode is adopted to demodulate the signal; and the power supply cable serves as a channel for carrier transmission, and realizes real-time bidirectional communication with a parallel communication circuit on the cable. The non-contact power supply electricity pick-up device provided by the invention is convenient to install and has relatively high electromagnetic coupling efficiency, improves guiding precision, expands a communication range and guarantees communication quality.

Description

technical field [0001] The invention is a non-contact power supply pickup with real-time communication function, which belongs to the technical field of automatic conveying equipment. Background technique [0002] With the introduction and development of Industry 4.0 and big data concepts in the manufacturing industry, manufacturing equipment is required not only to complete normal functions, but also to transfer various data to a unified platform for storage and centralized processing. Especially for various mobile devices, it is necessary to transfer data while completing the work. At present, if mobile devices use various types of wired transmission networks, they must be wired together with power supply lines. On the one hand, wiring is difficult and cumbersome, and on the other hand, strong electricity is easy to interfere. If a wireless network is used, although no wiring is required, it is limited by the frequency of wireless communication, susceptible to electromagn...
