[0037] Next, refer to Figures 1 to 5 A parts selection error prevention system 100 according to some embodiments of the present application is introduced in detail.

[0038] like Figures 1 to 5 As shown, the parts selection error prevention system 100 may include a computer 10 , an Internet of Things module 20 , a power supply module 40 , and corresponding parts indication circuits 50 , 60 .

[0039] The computer 10 may be configured to communicate with the production line in real time. For example, when a vehicle arrives at a target station in the production line, the computer 10 may obtain the parts selection information about the vehicle and generate or retrieve the corresponding parts selection instructions based on the parts selection information. Advantageously, the display device of the computer 10 may be configured to display the parts selection information corresponding to the parts selection instructions. This allows the staff to conveniently and intuitively grasp the exact parts selection information of the vehicle, so as to effectively check the actual selection situation.

[0040] The part selection information can characterize the specific part selection type or part selection method that the vehicle should implement at the target workstation. The part selection instructions can be understood as a series of executable instructions, such as an executable control program instruction set for the Internet of Things module 20, such as a high and low level sequence. The mapping relationship between the part selection information and the part selection instructions can be stored in a query file, such as a json file, in advance. It should be understood that the generation of the part selection instructions can be in a variety of ways. In some embodiments, the part selection instructions can be manually input into the computer 10 by an operator. In some embodiments, the part selection instructions can be sent to the computer 10 by an external computing device. In some embodiments, the part selection instructions can be obtained by processing the computer 10 itself. It should be understood that the relevant technology of receiving information by the computer 10 and generating instructions based on the information is known in the prior art and will not be repeated here.

[0041] like Figure 2As shown, the Internet of Things module 20 can be configured to communicate with the computer 10 and the Internet of Things module 20 can be configured to obtain the part selection instruction from the computer 10. The Internet of Things module 20 can be understood as a small intelligent device, in which a communication module (the following logic level interface 21, Bluetooth communication unit 22, and / or mobile hotspot communication unit 23), a processing module 24, an input and output module 25, and / or a storage module 26, etc. can be integrated. The Internet of Things module 20 is widely used in the fields of smart home, industrial automation, smart agriculture, and health monitoring.

[0042] like Figure 2 As shown, in some embodiments, the Internet of Things module 20 may include a logic level interface 21. In order to achieve a reliable and efficient communication connection between the computer 10 and the Internet of Things module 20, the part selection error prevention system 100 may include a selectively set communication conversion module 30, and the Internet of Things module 20 may be configured to communicate with the computer 10 via the communication conversion module 30, and the Internet of Things module 20 is configured to obtain a part selection instruction from the computer 10 via the communication conversion module 30.

[0043] Additionally or alternatively, the Internet of Things module 20 may include a Bluetooth communication unit 22. This allows the Internet of Things module 20 to communicate with the computer 10 or other smart devices, such as a mobile terminal, via Bluetooth.

[0044] Additionally or alternatively, the Internet of Things module 20 may include a mobile hotspot communication unit 23. This allows the Internet of Things module 20 to perform mobile hotspot communication with the computer 10 or other smart devices, such as mobile terminals. Particularly advantageously, based on the communication architecture combining the fifth generation mobile communication and the mobile hotspot, the parts selection error prevention system 100 of the present application can obtain improved system anti-interference performance, thereby ensuring reliable and efficient communication quality.

[0045] Advantageously, the power supply module 40 can provide power input for multiple electrical devices. Figure 1 As shown, the parts selection error prevention system 100 may include an assembly board, such as one or more circuit boards, and the Internet of Things module 20, the power supply module 40, and the operating switches 51 and 61 for the corresponding parts indication circuits may be integrated on the assembly board 70. Advantageously, the parts selection error prevention system 100 may also include a circuit breaker 80 integrated on the assembly board 70, and the circuit breaker 80 may be configured to cut off the power supply input provided by the power supply module 40.

[0046] The power supply module 40 can effectively power the Internet of Things module 20 and the corresponding part indication circuit. In some embodiments, the power supply module 40 may include or be configured as a rectifier module. The rectifier module may include an AC input and a DC output circuit, the AC input may be configured to be connected to an AC power grid, and the DC output circuit may be configured to be connected to the corresponding part indication circuit as a power supply input. Thus, continuous power supply can be provided to the corresponding electrical device through the AC power grid. Additionally or alternatively, the power supply module 40 may include or be configured as a DC converter module. The DC converter module may include a DC input and a DC output circuit, the DC input may be configured to be connected to a battery, and the DC output circuit may be configured to be connected to the corresponding part indication circuit as a power supply input. Thus, flexible power supply can be provided to the corresponding electrical device through the battery. Additionally or alternatively, the power supply module 40 may include or be configured as an inverter module. The inverter module may include a DC input and an AC output circuit, the DC input may be configured to be connected to a battery, and the AC output circuit may be configured to be connected to the corresponding part indication circuit as a power supply input. Thus, flexible power supply can be provided to the corresponding AC electrical device through the battery.

[0047] Advantageously, the parts selection error prevention system 100 may include at least two parts indication circuits, namely a first parts indication circuit 50 and a second parts indication circuit 60. Figure 4 and 5 As shown, the first part indication circuit 50 may include a power supply input, a first operating switch 51 and a first indicator 52, and the first indicator 52 may be assigned to a first optional part. The second part indication circuit 60 may include a power supply input, a second operating switch 61 and a second indicator 62, and the second indicator 62 may be assigned to a second optional part different from the first optional part.

[0048] A first control connection for controlling the switch state of the first operating switch 51 may be provided between the Internet of Things module 20, for example, the processing module 24 thereof, and the first operating switch 51, and a second control connection for controlling the switch state of the second operating switch 61 may be provided between the Internet of Things module 20, for example, the processing module 24 thereof, and the second operating switch 61. In other words, the Internet of Things module 20 may close the corresponding part indication circuit by controlling the switch state of the corresponding operating switch, and then activate the corresponding indicator to instruct the staff to select the appropriate optional parts.

[0049] The activated first indicator 52 or the second indicator 62 can intuitively and clearly inform the staff whether the optional part assigned to the vehicle is the first optional part or the second optional part. As an example, the first optional part can represent red paint for the vehicle body, while the second optional part can represent blue paint for the vehicle body. As an example, the first optional part can represent a first hub type for the wheel, while the second optional part can represent a second hub type for the wheel.

[0050] In some embodiments, the first control switch 51 can be configured as a first relay switch, which can include a control circuit and an output circuit, and the second control switch 61 can be configured as a second relay switch, which can include a control circuit and an output circuit. The Internet of Things module 20 can access the control circuit of the first relay switch via the first control connection, and the Internet of Things module 20 can access the control circuit of the second relay switch via the second control connection. The output circuit of the first relay switch can be connected to the first part indication circuit 50, and the output circuit of the second relay switch can be connected to the second part indication circuit 60. Thus, the Internet of Things module 20 can control the state of the output circuit of the relay switch by controlling the state of the control circuit of the corresponding relay switch. Generally, the control circuit of the relay switch can include an electromagnetic component, and the on and off of the output circuit of the relay switch can be controlled in a linkage manner by energizing the electromagnetic component. Since the control principle of the relay switch is known to those skilled in the art, it will not be repeated here.

[0051] In some embodiments, in order to intuitively and clearly inform the staff of the optional parts assigned to the vehicle, the first indicator 52 is configured as a first visual indicator for indicating the first optional part, and the second indicator 62 is configured as a second visual indicator for indicating the second optional part, wherein the first visual indicator and the second visual indicator have different visual presentations. Thus, the staff can be visually informed of the optional parts assigned to the vehicle, for example, in different colors. For example, the first visual indicator can be configured as a first lighting device that can emit a first color light, such as red light, and the second visual indicator can be configured as a second lighting device that can emit a second color light, such as blue light.

[0052] Additionally or alternatively, the first indicator 52 may be configured as a first door device for indicating a first optional part, and the second indicator 62 may be configured as a second door device for indicating a second optional part. The first door device may be configured to open when the part selection indication corresponds to the first optional part, and the second door device may be configured to open when the part selection indication corresponds to the second optional part. The door device may be used to clearly inform the staff of the optional parts assigned to the vehicle, and further improve the level of error-proofing of part selection.

[0053] Additionally or alternatively, the first indicator 52 can be configured as a first acoustic indicator for indicating a first optional part, and the second indicator 62 can be configured as a second acoustic indicator for indicating a second optional part, wherein the first visual indicator and the second visual indicator have different acoustic presentations, thereby enabling the operator to be informed of the optional parts assigned to the vehicle in a different manner, such as by different voice announcements or music playbacks.

[0054] Additionally or alternatively, the part selection error prevention system 100 may further include more part indication circuits, for example, may additionally include a third part indication circuit, the third part indication circuit including a power supply input, a third control switch and a third indicator, the third indicator being assigned to a third optional part different from the first optional part and the second optional part. The third indicator is configured as a third visual indicator, a third door device or a third auditory indicator for indicating the third optional part.

[0055] The parts selection error proofing system 100 of some embodiments of the present application can allow a reliable implementation of the parts selection error proofing scheme and is particularly cost-effective. In addition, the parts selection error proofing system 100 of some embodiments of the present application can also provide a parts selection error proofing scheme with a simple structure and cost-effectiveness.
