Description

Technical Field

[0001] The present invention relates to the field of contactless energy transmission, and in particular to a contactless energy transmission, energy storage and wireless communication system for a shuttle vehicle and a use method thereof. Background Art

[0002] The multi-layer shuttle is a material handling equipment widely used in stereoscopic warehouses of various industries. Together with shelves and in-and-out elevators, it forms a multi-pass stereoscopic warehouse system. The clamp-type multi-layer shuttle is more widely used because it has the ability to handle materials of variable sizes. The telescopic fork is the actuator on the shuttle. After the shuttle is in place, the fork quickly retracts and retracts to pick up and place goods. As a key component of the shuttle, the telescopic fork of the traditional multi-layer shuttle is driven by a slide rail and a synchronous belt. The power supply and communication wires are placed inside the synchronous belt. As the fork moves back and forth repeatedly, it is very easy to cause the power supply and communication wires inside the synchronous belt to break or have poor contact, resulting in errors in the operation of the multi-layer shuttle. In response to the above problems, a method and device for non-contact energy transmission, energy storage and wireless communication are provided to provide power and communication functions for the telescopic fork of the multi-layer shuttle, thereby ensuring the reliable operation of the multi-layer shuttle. Summary of the invention

[0003] The purpose of the present invention is to solve the problem that the internal power supply and communication wires of the synchronous belt are easily broken or have poor contact due to the continuous back and forth movement of the telescopic fork of the multi-layer shuttle. In view of the above-mentioned problems, a non-contact energy transmission, energy storage and wireless communication system and use method for the shuttle are provided to provide power supply and communication functions for the telescopic fork of the multi-layer shuttle, thereby ensuring the reliable operation of the multi-layer shuttle.

[0004] The technical solution of the present invention is as follows:

[0005] The present invention discloses a system for contactless energy transmission, energy storage and wireless communication of a shuttle vehicle, comprising a transmitting end and a receiving end, wherein the transmitting end is arranged on the inner side of the vehicle body, and the receiving end is arranged on the side of a telescopic fork; the transmitting end comprises a power module, a protection module, a high-frequency inverter module, a transmitting coil, a dip switch, an RS485 bus, a CPU module, and a wireless communication module; the receiving end comprises a receiving coil, a synchronous rectification module, a DC-DC conversion module, a wireless communication module, a CPU module, a charging module, a lithium battery, a dip switch, and an RS485 bus.

[0006] Furthermore, the direct current output by the power supply is converted into alternating current by a high-frequency inverter module, and coupled to the receiving end through a transmitting coil to realize a contactless power supply function.

[0007] Furthermore, the controller of the shuttle vehicle communicates with the transmitting end via the RS485 bus, and realizes the wireless transparent transmission function with the receiving end via the wireless communication module.

[0008] Furthermore, the high-frequency alternating current output by the transmitting coil is converted into direct current through the synchronous rectification module, and then outputs a constant 24V voltage output through the DC-DC conversion module to power the telescopic fork. When the receiving end leaves the effective range of the transmitting end, the lithium battery of the receiving end will automatically switch to the DC-DC conversion module to continue to maintain the voltage output. The wireless communication module realizes the wireless transparent transmission function with the transmitting end to provide communication services for the telescopic fork.

[0009] Furthermore, the direct current charges the lithium battery via the charging module to provide backup power.

[0013] Furthermore, the power supply step includes:

[0014] S11: The internal power supply of the shuttle provides DC input for the transmitter. When the input voltage is too low, too high, overcurrent, or reverse connection, the protection module disconnects the power input to protect the internal sub-modules. The high-frequency inverter module is controlled by the CPU to convert DC power into AC power, which is coupled to the receiving end through the transmitting coil to realize the contactless power supply function.

[0015] S12: The high-frequency alternating current coupled to the coil of the receiving end is converted into direct current through the synchronous rectification module, and then outputs a constant 24V voltage output through the DC-DC conversion module to power the telescopic fork. The DC power is also charged by the charging module to provide backup power. When the receiving end leaves the effective range of the transmitting end, the lithium battery of the receiving end will automatically switch to the DC-DC conversion module to continue to maintain the voltage output. When the receiving end returns to the effective range of the transmitting end, the charging module restarts to charge the lithium battery.

[0016] Further, the communication step includes:

[0017] S21: The sending end is connected to the shuttle car main controller using RS485 bus. The sending end receives data and packages the ID of the dip switch, and sends it to the receiving end through the wireless communication module. After receiving the data from the receiving end, it first verifies the correctness of the data and checks whether the ID value matches its own ID value. If it does not match, the data will be discarded and finally forwarded to the shuttle car main controller through the RS485 bus to realize the data wireless transparent transmission function.

[0018] S22: The receiving end is connected to the telescopic fork through the RS485 bus. After the wireless communication module receives the data from the sending end, it first verifies the correctness of the data and checks whether the ID value matches its own ID value. If it does not match, the data will be discarded and then forwarded to the telescopic fork through the RS485 bus. The receiving end receives the data from the fork and packages the ID of the dip switch and sends it to the sending end through the wireless communication module, realizing the wireless data transmission function.

The high-frequency AC power coupled to the receiving coil is converted into DC power by the synchronous rectification module, and then outputs a constant 24V voltage output through the DC-DC conversion module to power the telescopic fork. This DC power is also used to charge the lithium battery through the charging module to provide backup power. When the receiving end leaves the effective range of the transmitting end, the lithium battery of the receiving end will automatically switch to the DC-DC conversion module to continue to maintain the voltage output.

When the receiving end leaves the effective range of the transmitting end, the lithium battery of the receiving end will automatically switch to the DC-DC conversion module to continue to maintain the voltage output. When the receiving end returns to the effective range of the transmitting end, the charging module restarts to charge the lithium battery.

[0035] Additionally, the communicating step includes:

[0036] S21: The sending end is connected to the shuttle car main controller using RS485 bus. The sending end receives data and packages the ID of the dip switch, and sends it to the receiving end through the wireless communication module. After receiving the data from the receiving end, it first verifies the correctness of the data and checks whether the ID value matches its own ID value. If it does not match, the data will be discarded and finally forwarded to the shuttle car main controller through the RS485 bus to realize the data wireless transparent transmission function.

After the wireless communication module receives the data from the sending end, it first verifies the correctness of the data and checks whether the ID value matches its own ID value. If it does not match, the data will be discarded and then forwarded to the telescopic fork through the RS485 bus.
