Description

TECHNICAL FIELD

[0001] The present application belongs to the field of vehicle charging, and particularly relates to a charging pile, a charging method, an electronic device and a storage medium. BACKGROUND

[0002] Automated Guided Vehicle (AGV) refers to a vehicle equipped with an automatic guiding system, which can automatically travel along a specified navigation path without manual guidance, and automatically transport goods or materials from the starting point to the destination. When AGV is working, a large amount of static charge will be accumulated in each part of the vehicle body. If the static charge of AGV accumulates too much, it will interfere with the normal operation of AGV, and when AGV transports goods, it will also release static charge to the connected goods, racks and equipment, causing damage to other equipment or devices.

[0003] A common way to release the accumulated net charge in AGV is to set a metal piece, such as a grounding pin, inside the charging interface of AGV. When AGV is charging, the charging pile of the charging interface fully contacts, and the grounding of AGV can be completed through the metal piece inside the charging interface to release the net charge on AGV.

[0004] However, the method of setting a metal piece inside the AGV charging interface will cause the charging interface to increase in size or become more complex. When the AGV charging interface deviates during docking with the charging pile, other structural components may be contacted first, which will cause the static charge on the AGV to not be released according to the preset path, and will cause damage to the AGV, the charging pile or the connected devices.

[0027] The charging pile grounding assembly 10 is located at the bottom of the charging pile body, the charging pile grounding assembly 10 is grounded when the charging pile works, and the charging pile grounding assembly 10 has a structure matched with the grounding assembly of the guide vehicle chassis; the detection assembly 20 is located on the charging pile grounding assembly 10, and the detection assembly 20 is used to detect the docking state of the charging pile grounding assembly 10 and the grounding assembly of the guide vehicle chassis; the control assembly 30 is connected with the detection assembly 20, and is used to determine whether the charging assembly 40 supplies power according to the docking state; the charging assembly 40 is connected with the control assembly 30, and the charging assembly 40 is used to charge the guide vehicle according to the indication of the control assembly 30.

[0028] In the embodiments of the present application, the guide vehicle chassis is provided with a grounding assembly, which is used to dock with the charging pile grounding assembly 10 to complete the reliable grounding requirement of the guide vehicle charging. As Figure 1As shown, the charging pile provided by the embodiment of the application includes a charging pile grounding assembly 10, a detection assembly 20, a control assembly 30 and a charging assembly 40. The charging pile grounding assembly 10 is in reliable contact with the bottom of the charging pile body through a structural member and a fixing screw, that is, the charging pile grounding assembly 10 is located at the bottom of the charging pile body. The charging pile grounding assembly 10 is used to be connected with the grounding assembly of the guide vehicle chassis, so as to ensure that the guide vehicle is in reliable contact with the charging pile grounding assembly 10 after the guide vehicle is parked in place, and the contact requirement meets the requirement of the EN62477 standard. The detection assembly 20 is installed on the charging pile grounding assembly 10 and communicates with the control assembly 30 to realize information interaction. The detection assembly 20 can detect the connection state of the charging pile grounding assembly 10 and the grounding assembly of the guide vehicle chassis, that is, whether the charging pile grounding assembly 10 is successfully connected with the grounding assembly of the guide vehicle chassis and whether the guide vehicle is parked in place. When the guide vehicle is parked in place, the detection assembly 20 outputs an electrical signal to the control assembly 30. The control assembly 30 can also be connected with the charging assembly 40 to realize information interaction. The communication mode between the control assembly 30 and other assemblies can be CAN, 485 mode, WIFI and the like.

[0029] Specifically, after the guide vehicle drives to the pre-charging position, the guide vehicle first adjusts the position and the direction of the whole vehicle by reversing and connects with the charging pile. The grounding assembly of the guide vehicle chassis is connected with the charging pile grounding assembly 10 to realize grounding, which can ensure that the guide vehicle is grounded first and can discharge the static electricity accumulated on the guide vehicle through the grounding assembly of the guide vehicle chassis and the charging pile grounding assembly 10, so as to avoid the problem that the static electricity is not released according to the preset path and the guide vehicle, the charging pile or the connecting device is damaged. At this time, the grounding assembly of the guide vehicle chassis is connected with the charging pile grounding assembly 10, the detection assembly 20 detects the signal that the grounding assembly of the guide vehicle chassis is connected with the charging pile grounding assembly 10, and converts the signal into an IO / level and sends it to the control assembly 30. The control assembly 30 of the charging pile judges that the contact is in place. After the charging pile detects the battery voltage, the control assembly 30 receives the charging control command of the guide vehicle master control through information interaction and charges the guide vehicle through the charging assembly 40.

[0030] In addition, as Figure 2The structure of another charging pile shown in the schematic diagram, the charging pile can also include human-computer interaction component 60, wireless module 70, charging component 40 can include charging module 401, interface board 402, charging interface 403.

Control component 30 is used for all control logic in the system, including: charging module 401 signal acquisition, conversion, control; human-computer interaction component 60 control; interface board 402 logic control; detection component 20 signal interaction; wireless module 70 information interaction, etc.

[0031] The above-mentioned human-computer interaction component 60 can be a display screen, an indicator light, a button and the like, which is used for human-computer interaction, so that the user can simply and clearly understand the state of the charging pile. The above-mentioned charging module 401 is used for converting alternating current into direct current required by AGV, and the charging module 401 can have a communication mode, which can support the control command of the charging pile control component 30, the command including but not limited to power on, power off, voltage value setting, current value setting, and the state information and various alarm information of the charging module 401 can be uploaded in real time through the communication protocol. The above-mentioned interface board 402 is used for connecting the charging module 401 and the charging interface 403. The above-mentioned charging interface is used for docking with the charging interface 403 of the guide vehicle, completing the connection of the charging loop between the charging pile and the guide vehicle. The above-mentioned wireless module 70 is used for online management of the charging pile, and the communication mode of the wireless module 70 can be 4 / 5G, WIFI, etc.

[0032] In the embodiment of the present application, the charging pile comprises: a charging pile grounding assembly 10, which is located at the bottom of the charging pile body. Specifically, the charging pile grounding assembly 10 is located at the front side of the bottom of the charging pile body and is consistent with the direction in which the charging interface 403 protrudes. The charging pile grounding assembly 10 is grounded when the charging pile is working. The charging pile grounding assembly 10 has a structure matched with the grounding assembly of the guide vehicle. A detection assembly 20 is located on the charging pile grounding assembly 10. The detection assembly 20 is used to detect the docking state of the charging pile grounding assembly 10 and the grounding assembly of the guide vehicle chassis. A control assembly 30 is connected with the detection assembly 20 and is used to determine whether the charging assembly 40 supplies power according to the docking state. The charging assembly 40 is connected with the control assembly 30. The charging assembly 40 is used to charge the guide vehicle according to the indication of the control assembly 30. The grounding is achieved by the docking of the charging pile grounding assembly 10 and the grounding assembly of the guide vehicle chassis. The static electricity accumulated on the guide vehicle can be discharged through the grounding assembly of the guide vehicle chassis and the charging pile grounding assembly 10. The problem that the guide vehicle, the charging pile or the docking device is damaged due to the fact that the static electricity is not released according to the preset path is avoided. Moreover, the charging pile comprises the detection assembly 20, which can ensure that the grounding assembly of the guide vehicle chassis is docked in place with the charging pile grounding assembly 10, thereby ensuring that the overall structure of the guide vehicle is effectively grounded.

[0033] In an implementation manner, the charging pile further comprises:

[0034] A limiting assembly 50 is located on the side wall of the charging pile body. The limiting assembly 50 is used to control the distance between the charging pile body and the guide vehicle to be greater than or equal to a preset distance.

[0035] Specifically, as shown in Figure 2 The charging pile further comprises a limiting assembly 50. The limiting assembly 50 is located on the side wall of the charging pile body. The limiting assembly 50 and the charging pile grounding assembly 10 are located on the same side. The limiting assembly 50 is used to control the distance between the charging pile body and the guide vehicle to be greater than or equal to a preset distance. That is, when the detection assembly 20 detects that the docking between the grounding assembly of the guide vehicle chassis and the charging pile grounding assembly 10 is abnormal, the limiting assembly 50 can limit the position of the guide vehicle by the distance between the charging pile body and the guide vehicle, thereby preventing the guide vehicle chassis from rubbing against the charging pile grounding assembly 10 and being crushed. Moreover, the limiting assembly 50 can limit the depth of the docking between the charging pile and the guide vehicle, thereby ensuring that the grounding assembly of the guide vehicle chassis is not misaligned with the charging pile grounding assembly 10 and is not crushed, and avoiding the damage of the grounding brush block 102 in the charging pile grounding assembly 10.

[0036] In an implementation manner, the charging pile grounding assembly 10 comprises:

[0037] A base plate 101 is used for support; a grounding brush block 102 is disposed on the base plate 101 and is used to connect with the grounding component of the guided vehicle chassis; a compression component 103 is located on the grounding brush block 102 and is used to increase the contact force between the grounding brush block 102 and the grounding component of the guided vehicle chassis.

[0038] Specifically, Figure 3 This document shows a schematic diagram of the structure of a charging pile grounding assembly 10 according to an embodiment of this application. Figure 3 As shown, the charging pile grounding assembly 10 consists of a base plate 101, a grounding brush block 102, and a detection assembly 20. The base plate 101 provides support or grounding. One end of the grounding brush block 102 is fixed to the base plate 101 with screws, and the other end is fitted with a movable compression assembly 103. The detection assembly 20 is located on one side of the grounding brush block 102. When the guided vehicle enters the charging position, the grounding brush block 102 contacts the grounding assembly of the guided vehicle's chassis. The compression assembly 103 increases the contact force between the grounding brush block 102 and the grounding assembly of the guided vehicle's chassis, ensuring reliable contact. Furthermore, the electrical contact portion of the charging interface 403 is located behind the grounding brush block 102 of the grounding assembly 10, ensuring priority grounding when the guided vehicle docks with the charging pile.

[0039] In one implementation, the charging pile grounding assembly 10 further includes:

[0040] A wiring hole 104 is located on the side wall of the base plate 101. The wiring hole 104 is used to place a grounding cable. One end of the grounding cable is connected to the grounding brush block 102, and the other end of the grounding cable is connected to the grounding terminal of the charging pile.

[0041] like Figure 3 As shown, the side wall of the base plate 101 of the charging pile grounding assembly 10 is provided with a wiring hole 104. The wiring hole 104 is used to place the grounding cable. One end of the grounding cable is connected to the fixing hole of the grounding brush block 102 through a fixing screw, and the other end of the grounding cable can be connected to the grounding end of the charging pile. In this way, when the grounding assembly of the guide vehicle chassis contacts the grounding brush block 102 of the charging pile grounding assembly 10, the grounding of the guide vehicle and the charging pile can be achieved through the grounding cable in the wiring hole 104. In addition, reliable contact with the charging pile ground can also be achieved by installing the assembly.

[0042] In one implementation, the charging component 40 includes:

[0043] A charging circuit for charging the guided vehicle; a relay located on the charging circuit, which, when powered, connects the charging circuit and, when powered off, disconnects the charging circuit; and a relay power supply circuit for supplying power to or disabling power to the relay.

[0044] In this embodiment of the application, the charging assembly 40 further includes a charging circuit, a relay, and a relay power supply circuit. The charging circuit is used to charge the guided vehicle. The relay is located on the charging circuit. When the relay is powered, it can be used to turn on the charging circuit. When the relay is de-energized, it is used to turn off the charging circuit. The relay power supply circuit is used to power the relay or to disable the power supply to the relay.

[0045] Specifically, the relay is located in the interface board 402, which has a signal control interface, a charging module 401 sampling signal, and a battery voltage sampling signal. The charging module 401 voltage sampling signal and the battery voltage sampling signal are used for relay logic judgment. The relay is used to disconnect or engage the charging circuit between the charging module 401 output and the guided vehicle. The power supply status of the relay is controlled by a control signal received from the signal interface, which is sent by the control component 30. This signal control can be a high / low level, an I / O signal, or a communication protocol.

[0046] Figure 4 This application illustrates a relay control circuit according to an embodiment of the present application, such as... Figure 4 As shown, when the control component receives the charging start command from the guided vehicle, it compares the voltage acquisition and battery voltage acquisition signals output by the adapter board. If the difference is less than or equal to a preset difference, it issues a relay energizing control command. The control component triggers the Out high level, pulling V_K low, forming a circuit with a voltage equal to V between signals V and V_K. This circuit powers the relay. After the relay coil is powered, it closes the normally open contact, conducting the charging circuit, and the charging pile charges the guided vehicle's battery. When the charging pile's control component receives the guided vehicle's charging completion shutdown command through information interaction, the main control center issues a shutdown command to the charger. After a preset delay, it sets the Out low level, raising V_K high. There is no electrical circuit between signals V and V_K. After the relay coil discharges through D1, it opens the normally open contact, cutting off the charging circuit.

[0047] Figure 5 This is a schematic diagram of the external structure of a charging pile provided in an embodiment of this application, such as... Figure 5As shown, the charging interface 403 of the charging pile is provided with a limiting assembly 50, and the bottom of the charging pile is provided with a charging pile grounding assembly 10, which includes a grounding brush block 102 and a detection assembly 20. The limiting assembly 50 is used to limit the relative position of the guide vehicle and the charging pile, prevent the grounding brush block 102 of the charging pile grounding assembly 10 from being misaligned and stuck with the grounding assembly of the guide vehicle, avoid poor contact between the charging pile grounding assembly 10 and the guide vehicle grounding assembly, and avoid the misaligned guide vehicle grounding assembly causing damage to the charging pile grounding assembly 10 when the guide vehicle drives away after charging is completed. Moreover, the limiting assembly 50 can limit the depth of the docking of the charging pile and the AGV, ensure that the AGV grounding assembly and the charging pile grounding assembly 10 are not misaligned and stuck, and avoid damaging the grounding brush block 102 in the charging pile grounding assembly 10.

Figure 6 As shown, the guide vehicle grounding assembly 80 can be part of the chassis, or a rectangular stainless steel plate with a reverse corner. When the guide vehicle and the charging pile are docked, the charging pile grounding assembly 10 and the guide vehicle grounding assembly 80 are docked. The limiting assembly 50 of the charging pile limits the relative position of the guide vehicle grounding assembly 80 and the charging pile grounding assembly 10, ensures that the guide vehicle grounding assembly 80 does not exceed the charging pile grounding assembly 10, prevents the charging pile grounding assembly 10 from exceeding the guide vehicle grounding assembly 80, prevents the compression assembly of the charging pile grounding assembly 10 from being misaligned and stuck with the guide vehicle grounding assembly, and avoids damage to the charging pile grounding assembly 10 when the guide vehicle drives away.

Specifically, after the guide vehicle drives to the pre-charging position, the guide vehicle first adjusts the position and the whole vehicle direction by reversing, docks with the charging pile, and realizes grounding through the docking between the charging pile grounding assembly and the grounding assembly of the guide vehicle chassis, so that the guide vehicle can be preferentially grounded, the static electricity accumulated on the guide vehicle can be discharged through the grounding assembly of the guide vehicle chassis and the charging pile grounding assembly, and the problem that the guide vehicle, the charging pile or the docking device is damaged due to the release of static electricity not according to the preset path is avoided.

[0052] Step 704: docking the charging assembly with the charging interface of the guide vehicle.

[0053] Specifically, after the charging pile grounding assembly is docked with the grounding assembly of the guide vehicle chassis, the charging assembly can be docked with the charging interface of the guide vehicle.

[0054] Step 706: in the case that the charging pile grounding assembly is successfully docked with the grounding assembly of the guide vehicle chassis through the detection assembly, the control assembly controls the charging assembly to charge the guide vehicle.

[0055] Specifically, the detection assembly is further arranged on the charging pile grounding assembly, the detection assembly is installed on the charging pile grounding assembly, and the detection assembly and the control assembly realize information interaction through communication. The detection assembly can detect the docking state of the charging pile grounding assembly and the grounding assembly of the guide vehicle chassis, that is, whether the charging pile grounding assembly is successfully docked with the grounding assembly of the guide vehicle chassis and whether the guide vehicle is parked in place. When the guide vehicle is parked in place, the detection assembly outputs an electric signal to the control assembly. The control assembly can also be connected with the charging assembly to realize information interaction, and the communication mode between the control assembly and other assemblies can be CAN, 485 mode, WIFI, etc. The grounding assembly installed on the guide vehicle chassis is docked with the charging pile grounding assembly, the detection assembly detects the signal that the grounding assembly of the guide vehicle chassis is docked with the charging pile grounding assembly, and converts the signal into IO / level and sends it to the control assembly. The control assembly of the charging pile judges that the contact is in place. After the charging pile detects the battery voltage, the control assembly receives the charging control command of the guide vehicle master control through information interaction, and charges the guide vehicle through the charging assembly.

[0056] In the embodiment of the present application, the charging pile grounding assembly is connected with the grounding assembly of the guide vehicle chassis to ground the guide vehicle, the charging pile grounding assembly is located at the bottom of the charging pile body, the charging assembly is connected with the charging interface of the guide vehicle, the control assembly controls the charging assembly to charge the guide vehicle when the detection assembly detects that the charging pile grounding assembly is successfully connected with the grounding assembly of the guide vehicle chassis, the grounding is realized by connecting the charging pile grounding assembly with the grounding assembly of the guide vehicle chassis, which can ensure that the guide vehicle is preferentially grounded, and the static electricity accumulated on the guide vehicle can be discharged through the grounding assembly of the guide vehicle chassis and the charging pile grounding assembly, thereby avoiding the problem that the static electricity is not released according to the preset path, which causes damage to the guide vehicle, the charging pile or the connecting device, and the charging pile includes the detection assembly, which can ensure that the grounding assembly of the guide vehicle chassis is connected with the charging pile grounding assembly in place, thereby ensuring that the overall structure of the guide vehicle is effectively grounded.

[0057] In an implementation manner, after the charging pile grounding assembly is connected with the grounding assembly of the guide vehicle chassis, the method further includes:

[0058] The distance between the charging pile body and the guide vehicle is greater than or equal to a preset distance by the limiting assembly.

[0059] Specifically, after the charging pile grounding assembly is connected with the grounding assembly of the guide vehicle chassis, the distance between the charging pile body and the guide vehicle can be greater than or equal to a preset distance by the limiting assembly. The limiting assembly is located on the side wall of the charging pile body, and is used to control the distance between the charging pile body and the guide vehicle to be greater than or equal to a preset distance, that is, when the detection assembly detects that the grounding assembly of the guide vehicle chassis is abnormally connected with the charging pile grounding assembly, the limiting assembly can limit the position of the guide vehicle by the distance between the charging pile body and the guide vehicle to prevent the guide vehicle chassis from rubbing against the charging pile grounding assembly and being crushed, and the limiting assembly can also limit the depth of the connection between the charging pile and the guide vehicle, thereby preventing the grounding assembly of the guide vehicle chassis from being misaligned and crushed, and avoiding damage to the grounding brush block in the charging pile grounding assembly.

[0060] In addition, the state of the charging pile can be understood by the user through human-computer interaction, and the AC power can be converted into DC power required by the AGV through the charging module. The charging module can have a communication mode, can support the control command of the charging pile main control component, and the control command includes but is not limited to power-on, power-off, voltage value setting, current value setting, and can upload the state information and various alarm information of the charging module in real time through the communication protocol. The charging module and the charging interface can be connected through the interface board. The charging interface is used for docking with the charging interface of the guide vehicle to complete the connection of the charging loop between the charging pile and the guide vehicle. The wireless module is used for online management of the charging pile, and the communication mode of the wireless module can be 4 / 5G, WIFI or the like.

[0063] The charging pile grounding assembly comprises a bottom plate, a grounding brush block, a detection assembly and a compression assembly. One end of the grounding brush block is fixedly arranged on the bottom plate through a screw, and the other end is provided with a movable compression assembly. When the guide vehicle enters the charging position, the grounding brush block contacts with the grounding assembly of the guide vehicle chassis, and the compression assembly is used to increase the contact force between the grounding brush block and the grounding assembly of the guide vehicle chassis, so that reliable contact is ensured.

[0064] In an implementation manner, after the grounding brush block is connected with the grounding assembly of the guide vehicle chassis, the method further comprises:

Thus, when the grounding assembly of the guide vehicle chassis contacts with the grounding brush block of the charging pile grounding assembly, the grounding of the guide vehicle and the charging pile can be realized through the grounding cable in the wiring hole. In addition, reliable contact with the ground of the charging pile can also be realized through the mounting assembly.

[0067] In an implementation manner, the control component controls the charging component to charge the guide vehicle, and the method comprises:

[0068] In a case where the control component determines that the difference between the output voltage of the charging component and the battery voltage of the guided vehicle is less than or equal to a preset difference value, the control component controls a relay power supply circuit to supply power to a relay to attract the normally open contact of the relay; the relay with the normally open contact attracted turns on a charging circuit, and the charging circuit is used to charge the guided vehicle.

[0069] Specifically, as shown in Figure 4 When the control component receives a charging start command of the guided vehicle, and the difference between the output voltage of the adapter plate and the battery voltage of the guided vehicle is less than or equal to a preset difference value, the control component issues a relay attraction control instruction. The control component triggers Out high level, and pulls V_K low, so that a loop with a voltage equal to V is formed between signal V and V_K, and the loop supplies power to the relay. After the relay coil is powered, the normally open contact is attracted, the charging circuit is turned on, and the charging pile charges the battery of the guided vehicle.

[0070] In an implementation manner, after the control component controls the charging component to charge the guided vehicle, the method further includes:

[0071] In a case where the control component receives a guided vehicle charging completion instruction, the control component controls the relay circuit to stop supplying power to the relay to disconnect the normally open contact of the relay; and the relay with the normally open contact disconnected cuts off the charging circuit.

[0072] Specifically, as shown in Figure 4 When the control component of the charging pile receives a guided vehicle charging completion shutdown instruction through information interaction, the main control center issues a shutdown command to the charger, and after a preset delay time, the control component pulls Out low level and pulls V_K high, so that there is no electric loop between signal V and V_K. After the relay coil is discharged through D1, the normally open contact is disconnected to cut off the charging circuit.

[0074] When the AGV receives the charging command, it drives to a pre-charging position, adjusts the position and the whole vehicle direction through the ground code, and adopts the reverse driving mode to dock with the charging pile. At this time, the ground assembly installed on the AGV chassis is docked with the ground assembly of the charging pile, the detection assembly detects the signal and converts the signal into IO / level to the control assembly of the charging pile, the control assembly of the charging pile judges that the contact is in place. After the charging pile detects the battery voltage, it receives the charging control command of the AGV master through information interaction, and starts the charging module. At this time, the control assembly samples the output voltage of the charging module and the battery voltage, and when the difference between the two is less than or equal to the preset difference, the control assembly issues a relay control signal to the interface board, and the relay is attracted. The charging pile starts charging the AGV. When the AGV completes the charging task, it issues a charging completion and charging pile closing command to the control assembly of the charging pile through protocol interaction, and the control assembly of the charging pile receives the command, closes the charger and disconnects the relay. The AGV drives away from the charging position, the AGV ground assembly is separated from the charging pile ground assembly, and the charging task is completed.

[0075] Abnormal state: the detection element detects an abnormality, and the charging pile ensures that the AGV ground assembly and the charging pile ground assembly do not occur structural misalignment abnormal state through the limiting assembly. The limiting assembly limits the maximum distance of the AGV reverse and sets a detection signal. After the AGV detects the signal, an abnormal alarm is triggered, the charging task is exited, and an alarm log is uploaded for manual intervention to troubleshoot.
