Problems solved by technology

[0003] However, the current known AGV rechargeable battery charging device still adopts the plug-in form. When the AGV drives to a special charging position, the worker needs to untie the plug on the AGV and pull it out, and insert it into the socket of the charging position. Workers need to pull out the plug and store it on the AGV
The entire charging process requires manual intervention, and it is difficult to achieve true automation and intelligence, which greatly affects the popularization and use of AGV

Embodiment 1

[0040] In order to adopt the wireless coupling power transmission method to realize the automatic charging of the heavy-duty AGV trolley, this embodiment provides a heavy-duty AGV trolley high-power wireless energy transmission system, such as figure 1 As shown, it includes an AGV console, an energy transmitter and a vehicle receiver. The energy transmitter includes a plurality of electric control cabinets, and a plurality of wireless energy transmission coils connected to the plurality of electric control cabinets in one-to-one correspondence. The vehicle receiver includes a wireless energy pickup coil and a wireless energy pickup circuit connected to it. The vehicle receiver also includes a battery management system (BMS) connected to the wireless energy harvesting circuit.

[0041] The electric control cabinet communicates with the AGV console and the wireless energy pickup circuit, and the wireless energy pickup circuit communicates with the AGV console. The connection met...

Embodiment 2

[0054] Corresponding to the high-power wireless energy transmission system shown in Embodiment 1, the embodiment of the present invention provides a heavy-duty AGV car high-power wireless energy transmission control method, such as Figure 8 As shown, the specific steps include:

[0055] S01. All electric control cabinets are powered on and initialized, and self-inspection is completed;

[0056] S02. All electric control cabinets establish UDP communication threads between the energy transmitter, the AGV console, and the vehicle receiver, and all electric control cabinets send online heartbeats to the AGV console;

[0057] S1. When the AGV car travels to a charging station, the AGV console sends a charging command to the electric control cabinet corresponding to the charging station;

[0058]S2. The electric control cabinet forwards the charging command to the on-board receiver on the AGV car, and the on-board receiver communicates with the battery management system after obt...

Abstract

The invention relates to the technical field of wireless charging of mobile equipment, and particularly discloses a heavy-load AGV high-power wireless energy transmission system and a control method, and the transmission system is provided with an AGV console, an energy transmitting terminal and a vehicle-mounted receiving terminal. The energy transmitting terminal is provided with an electric control cabinet (comprising an energy transmitting circuit and a primary side control circuit) and a wireless energy transmitting coil, the vehicle-mounted receiving terminal is provided with a wireless energy pickup coil, a wireless energy pickup circuit (comprising an energy receiving circuit and a secondary side control circuit) and an AGV console, and the primary side control circuit and the secondary side control circuit are in communication connection in pairs. According to the system, a charging control instruction, a power-off control instruction and other instructions as well as battery state information, charging state information and other information are transmitted, so that power-on and power-off control of an energy transmitting line and an energy receiving line is realized, abnormity monitoring of an electric control cabinet and a vehicle-mounted receiving end by an AGV console is realized, the lines are cut off in time when abnormity occurs, and condition deterioration is avoided.

Description

technical field [0001] The invention relates to the technical field of wireless charging of mobile devices, in particular to a high-power wireless energy transmission system and a control method for a heavy-duty AGV trolley. Background technique [0002] AGV is the abbreviation of (Automated Guided Vehicle), which means "automatically guided transport vehicle". Functional transport cart. In order to achieve the best utility, the high utilization rate of AGV must be guaranteed. The AGV is powered by a rechargeable battery. When the voltage of the rechargeable battery is low, an alarm signal will be issued, and the AGV will automatically leave the production line and navigate to the designated charging location for charging. With the development of high-power rechargeable batteries, it is possible to allow the rechargeable batteries to be charged quickly within a few seconds. This technology allows the AGV to be fully charged without moving out of the production line during ...
