Problems solved by technology

The existing dynamic guidance technology generally uses a single wire or magnetic nail for line tracking, and the deviation detection accuracy is not high. For the dynamic wireless power supply system based on the energy emission guide rail, the deviation information detection cannot be well realized.
In addition, for coordinate positioning methods, such as ultrasonic positioning and GPS positioning, although accurate position calibration can be achieved, the detection accuracy is still not high enough, resulting in inaccurate position adjustment, and the anti-offset of the guide rail dynamic wireless charging system is still relatively large upside

Embodiment Construction

[0028] The embodiment of the present invention will be explained in detail below in conjunction with the accompanying drawings. The examples given are only for the purpose of illustration, and cannot be interpreted as limiting the present invention. The accompanying drawings are only for reference and description, and do not constitute the scope of patent protection of the present invention. limitations, since many changes may be made in the invention without departing from the spirit and scope of the invention.

[0029] This embodiment provides a position-correctable rail-type dynamic wireless charging system, including a primary-side structure (or called a transmitting end) and a secondary-side structure (or called a receiving end). Such as figure 1 As shown in the three-dimensional structure, the primary side structure includes a horizontally placed multi-segment rail-type wireless energy transmitting coil (abbreviated as energy transmitting rail or wireless energy transmit...

Abstract

The invention relates to the technical field of rail type dynamic wireless charging, and particularly discloses a guide rail type dynamic wireless charging system capable of correcting the position and a position correcting method thereof. A primary side structure of the system comprises multiple sections of guide rail type wireless energy transmitting coils and multiple sections of guide rail type primary side position detecting coils arranged on the two sides of the multiple sections of guide rail type wireless energy transmitting coils. A secondary side structure comprises a wireless energyreceiving coil matched with the multiple sections of guide rail type wireless energy transmitting coils and a secondary side position detection coil arranged above the wireless energy receiving coil.The current change of the primary side position detection coil is detected to reflect the coupling condition change of the primary side position detection coil and the secondary side position detection coil, so that the position deviation condition of the secondary side structure is detected, the position of the secondary side structure is further adjusted, the position deviation detection precision of the guide rail type dynamic wireless charging system is improved, the deviation resistance of the guide rail type dynamic wireless charging system is improved, and efficient energy transmissionof the primary side structure and the secondary side structure is achieved.

Description

technical field [0001] The invention relates to the technical field of rail-type dynamic wireless charging, in particular to a rail-type dynamic wireless charging system capable of correcting a position and a position correction method thereof. Background technique [0002] In track-type dynamic wireless charging applications, such as wireless charging systems for AGVs and inspection robots, it is an inevitable problem to detect whether the receiving end deviates from the charging track in real time and correct it. The existing dynamic guidance technology generally uses a single wire or magnetic nail for line tracking, and the deviation detection accuracy is not high. For the dynamic wireless power supply system based on the energy emission guide rail, the deviation information detection cannot be well realized. In addition, for coordinate positioning methods, such as ultrasonic positioning and GPS positioning, although accurate position calibration can be achieved, the dete...
