Embodiment Construction

[0026] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0027] see figure 1 , the specific working process of the wireless charging device of the present invention is as follows: the power grid inputs power frequency alternating current, and the rectifier rectifies the power frequency alternating current into direct current under the control of the power control module. The power control module is the driving circuit of the thyristor in the rectifier, which changes the output voltage of the rectifier by changing the initial conduction angle of the thyristor, and then controls the output power of the rectifier. The high-frequency inverter controls the g-pole under the PWM driver to ensure that the output current and voltage waveforms are as close as possible to the high-frequency sine wave. The high-frequency alternating current output by the high-frequency inverter resonates between...

Abstract

The invention discloses a cable tunnel inspection robot equipped with wireless charging equipment and a charging method for the robot. The wireless charging equipment comprises a transmitting unit, a receiving unit and a ZigBee communication module, wherein the receiving unit is mounted on the cable tunnel inspection robot; the transmitting coils in the transmitting unit are four equal-size circular coils which are arranged on the same plane and are connected in series mutually; a square is formed by the centers of the circular coils in a surrounding manner, and the circular coils are partially overlapped mutually; a charging battery in the receiving unit is used for supplying electric energy for the cable tunnel inspection robot; and a first controller in the transmitting unit and a second controller in the receiving unit are in wireless connection through the ZigBee communication module. According to the charging method disclosed by the invention, an RFID electronic tag is adopted to realize accurate positioning of the cable tunnel inspection robot, so that quick wireless charging of a dual-cable-rope guiding rail type cable tunnel inspection robot is realized.

Description

technical field [0001] The invention mainly relates to radio frequency identification technology RFID and wireless energy transmission technology, in particular to a cable tunnel inspection robot with wireless charging equipment and a charging method. Background technique [0002] Wireless power technology (wireless power transfer) devices do not need to use cables to connect the device to the power supply system, and can directly charge it quickly. In addition, non-contact fast charging can be arranged in a variety of places, and can provide charging services for various types of equipment, making it possible to charge anytime and anywhere. [0003] At present, wireless energy transmission technology mainly adopts electromagnetic resonance coupling technology, which is mainly realized by main components such as power supply, power output, power receiving, and rectifier. The difference from the electromagnetic induction charging method is that the magnetic resonance method ...
