Problems solved by technology

[0003] However, the environment where wireless charging can work is too limited at present. Traditional wireless charging uses transmitting and receiving coils for wireless charging. It cannot work normally in complex and harsh natural environments such as underwater and rainforest. Once the signal transmitting end and receiving end If water enters, the whole system will be completely paralyzed

Embodiment Construction

[0019] In order to describe the present invention more specifically, the technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0020] Such as figure 1 As shown, the present invention uses the distributed data acquisition system powered by the cable magnetic field, including an AC current source, an energy signal transmitting cable and a plurality of data acquisition units; wherein:

[0021] The AC current source feeds a high-frequency, high-current energy signal into the energy signal transmitting cable, and generates an alternating magnetic field around the cable through electromagnetic induction, and transmits it into space. In this embodiment, the AC current source uses a microprocessor to control the working state of the switch tube of the full-bridge inverter circuit, realizes DC-AC conversion, and generates a 100 kHz square wave signal to be fed into the cable.

Abstract

The invention discloses a distributed data acquisition system using a cable magnetic field for power supply. The distributed data acquisition system comprises an alternating current source, a cable, a wireless energy acquisition circuit, and a data acquisition device. The transmitting end of the system adopts an underwater cable having a complete waterproof function, and the wireless energy acquisition circuit and the data acquisition device are packaged in a completely sealed way, and therefore underwater working is realized. The magnetic field is generated in the signal transmitting cable of the transmitting end by the alternating current, and the current is sensed in peripheral wireless energy acquisition coils, and therefore a one-to-many wireless electric energy transmission system is realized. The data acquisition device is used to monitor environmental parameters, which are transmitted to an upper computer, and therefore real-time monitoring of underwater severe environment is realized.

Description

technical field [0001] The invention belongs to the technical field of wireless energy transmission and Internet of Things communication, and in particular relates to a distributed data acquisition system powered by a cable magnetic field. Background technique [0002] Wireless communication has been popular all over the world for nearly a hundred years. In recent years, wireless charging has become a hot spot and trend in the development of the world's electronics industry due to its convenience and easy distribution. At present, there are three main ways to realize wireless charging: inductive coupling, electromagnetic resonance, and microwave. These three technologies are respectively suitable for short-range, medium-short-range and long-range power transmission, among which inductive coupling is widely used. In the inductive coupling type, the alternating current of a certain frequency in the primary coil induces a certain current in the secondary coil through electromag...
