Description

Technical Field

[0001] The present invention relates to the field of vehicle technology, and in particular to a tire pressure matching error-proofing detection method, device, and storage medium. Background Art

[0002] At present, most automobile production lines use automatic tire pressure detection and matching equipment to match the vehicle tire pressure system. According to the failures that have occurred in the current automatic tire pressure detection and matching equipment, there are mainly the following situations: 1. Before the vehicle enters the tire pressure matching equipment antenna board, the employee needs to manually scan the vehicle VIN code; if the employee is absent from work or other work abnormalities, and starts to scan the vehicle VIN code after the front wheels of the vehicle have entered the tire pressure matching equipment antenna board, the antenna board cannot recognize the vehicle's front wheel ID at this time, and the equipment mistakenly identifies the rear wheels of this vehicle as the front wheel ID of this vehicle, and identifies the front wheels of the vehicle behind the assembly line as the rear wheel ID of this vehicle, and stores them in the OBD box, resulting in the four-wheel ID stored in the OBD box being inconsistent with the actual vehicle, and ultimately leading to errors when the OBD box writes to the vehicle's BCM; 2. Since the OBD box is wireless, employees can take the OBD box to any vehicle for writing at will; therefore, before employees take the OBD box to write the four-wheel ID into the vehicle's BCM through the vehicle diagnostic port, they must first check the VIN code in the OBD box. It is consistent with the actual vehicle VIN code. If an employee is absent from work or other operational abnormalities are not checked, the four-wheel ID written into the vehicle BCM will be inconsistent with the actual vehicle; 3. Since the tire pressure sensor will transmit tire pressure information at a regular interval and the transmission distance is relatively long, if the tire pressure sensors of other vehicles on the assembly line are in the information transmission state when this vehicle is performing tire pressure matching, the tire pressure equipment is likely to recognize the information transmitted by the tire pressure sensors of other vehicles, thereby mistakenly storing the tire IDs of other vehicles in the OBD box, and ultimately causing the four-wheel ID stored in the OBD box to be inconsistent with the actual tire ID of this vehicle; 4. When the antenna board of the tire pressure matching equipment reads the vehicle tire pressure sensor ID, due to the problem of the signal strength of the tire pressure sensor, it may cause the antenna board to recognize the right wheel ID when reading the vehicle's left wheel ID, or the antenna board to recognize the left wheel ID when reading the vehicle's right wheel ID, causing the left and right wheel IDs recognized by the antenna board of a vehicle to be completely consistent, and ultimately resulting in two duplicate tire IDs in a vehicle's BCM. Summary of the Invention

[0003] The present invention provides a tire pressure matching error prevention detection method, device and storage medium, so as to reduce the error rate of writing vehicle VIN code and tire ID, and reduce the error rate of vehicle tire pressure matching.

[0004] In order to realize the error rate of reducing the vehicle tire pressure matching, the embodiment of the present application provides a tire pressure matching error-proof detection method, comprising: when a first vehicle is detected by a vehicle body detection switch, a detection trigger signal is sent to an MES system, so that the MES system issues vehicle information of the first vehicle to a tire pressure matching device; wherein the vehicle body detection switch is located in front of the tire pressure matching device; the tire pressure matching device comprises a plurality of tire detection switches and a plurality of antenna boards; the vehicle information comprises a VIN code;

[0005] When the first tire of the first vehicle is detected by the tire detection switch to enter the detection range of the first antenna board, the first antenna board is controlled to send a low-frequency signal to a first tire pressure sensor built in the first tire to activate the first tire pressure sensor; according to the emission signal of the first tire pressure sensor, the ID information and the tire pressure information of the tire read by the first tire pressure sensor are obtained and written into the first vehicle;

[0006] When it is detected that any one of the VIN code of the first vehicle and the ID information of the four wheels does not meet the condition, the operation of the flow line is stopped, and an alarm is issued.

[0007] As a preferred scheme, after the first vehicle is detected by the vehicle body detection switch located in front of the tire pressure matching device, the first vehicle information is automatically triggered and sent to the tire pressure matching device by the MES system, without the need of scanning the vehicle VIN code by the staff, so as to reduce the error rate of the vehicle VIN code matching caused by the abnormal operation of the staff and reduce the tire ID writing error rate;

[0008] The present application utilizes the tire detection switch to detect the first tire, and then controls the antenna board to send a low-frequency signal to the tire pressure sensor to read the ID information and the tire pressure information of the first tire, only identifies the low-frequency signal emitted by the tire pressure sensor of the current vehicle, can accurately obtain the tire information of the current vehicle, does not accept the emission signal of the tire pressure sensor of other vehicles on the flow line, and reduces the tire ID writing error rate caused by the influence of other vehicles on the flow line.

[0009] After the vehicle VIN code and the ID information of the four wheels of the vehicle are obtained, error-proof comparison is performed to judge whether any one of them is wrong; and the error rate of writing the vehicle VIN code and the ID information of the four wheels of the vehicle is further reduced.

[0010] As a preferred scheme, after receiving the VIN code of the first vehicle entering the tire pressure matching device read by the code scanning gun, the VIN codes of N vehicles successively performing tire pressure matching are cached.

[0011] As a preferred solution, the present invention uses a barcode scanner to read the VIN code of the first vehicle entering the tire pressure matching device, calibrates the vehicle VIN code in the MES system, and caches the VIN codes of N vehicles that undergo tire pressure matching later. When the MES network fails and vehicle information cannot be sent down due to a fault, the device can use the cached N vehicle VIN codes to continue tire pressure matching, reducing the error rate of vehicle VIN code writing or the impact of the inability to write vehicle VIN codes due to MES network failure.

[0012] As a preferred solution, controlling the first antenna board to transmit a low-frequency signal to a first tire pressure sensor built into the first tire to activate the first tire pressure sensor, and obtaining tire ID information and tire pressure information read by the first tire pressure sensor based on the transmission signal sent by the first tire pressure sensor, specifically:

[0013] The first antenna board transmits a low-frequency signal to a first tire pressure sensor built into the first tire to activate the first tire pressure sensor so as to read the ID information and tire pressure information of the first tire. The first tire pressure sensor marks a first identification flag on the ID information and the tire pressure information. The first tire pressure sensor transmits the tire pressure information with the first identification flag via a transmission signal.

[0014] The first antenna board determines whether the received first transmission signal carries a first identification flag, and if so, obtains the tire ID information and tire pressure information read by the tire pressure sensor corresponding to the first transmission signal.

[0015] As a preferred solution, the present invention uses a tire detection switch to detect the first tire, and then controls the antenna board to send a low-frequency signal to the tire pressure sensor to read the ID information and tire pressure information of the first tire, and marks the ID information and the tire pressure information with a first identification flag; the antenna board performs flag screening on the received tire pressure information, marks the first identification flag on the tire pressure information activated by the low-frequency signal, and filters the tire pressure information that is not activated by the low-frequency signal, such as the tire pressure information automatically sent by the tire pressure sensor, and only receives the tire pressure information activated by the current low-frequency signal. It can accurately obtain the tire information of the current vehicle, does not accept the transmission signals of the tire pressure sensors of other vehicles on the assembly line, and reduces the tire ID writing error rate caused by the influence of other vehicles on the assembly line.

[0016] As a preferred solution, when it is detected that any one of the VIN code of the first vehicle and the ID information of the four wheels does not meet the conditions, the production line operation is stopped and an alarm is issued. Specifically:

[0017] Compare the ID information of the four wheels of the first vehicle with the ID information of the four wheels of the previous N vehicles. If it is detected that the ID information of any tire of the first vehicle is the same as the ID information of any tire of the previous N vehicles, the production line operation will be stopped and an alarm will be issued.

[0018] Use the wired OBD cable to connect the vehicle and scan the detection bar code of the current vehicle, obtain the VIN code of the current vehicle according to the detection bar code, and compare it with the VIN code of the MES system;

[0019] If the VIN code of the current vehicle is inconsistent with the VIN code of the MES system, the operation of the assembly line will be stopped and an alarm will be issued.

[0020] As a preferred solution, after obtaining the ID information of the vehicle's four wheels, the present invention compares it with the four-wheel ID information of the previous N vehicles to determine whether the ID information of the four wheels is incorrect, thereby avoiding the occurrence of tire ID duplication; the wireless form of the OBD box is upgraded to a wired OBD form, and the length of the OBD harness is fixed. The OBD harness can only be pulled to a single vehicle of the current tire pressure matching device to avoid vehicle tire ID writing errors caused by abnormal operations such as employees being absent from their posts and failing to verify that the VIN code in the OBD box is consistent with the VIN code of the actual vehicle, thereby further reducing the error rate of writing the ID information of the vehicle's four wheels.

[0021] As a preferred solution, the VIN code of the current vehicle is obtained according to the detection bar code and compared with the VIN code of the MES system, which also includes:

[0022] If the VIN code of the current vehicle is successfully compared with the VIN code of the MES system, the ID information and corresponding tire pressure information of all tires read by all tire pressure sensors are obtained, and the ID information and tire pressure information of all tires are written into the BCM of the first vehicle.

[0023] As a preferred solution, after obtaining the vehicle VIN code, the present invention allows employees to scan the detection bar code, and the system automatically performs a VIN comparison to determine whether the vehicle VIN code is incorrect. This avoids vehicle tire ID writing errors caused by employees failing to check whether the VIN code in the OBD box is consistent with the actual vehicle VIN code due to work abnormalities such as employees being absent from their posts, further reducing the error rate of vehicle VIN code writing.

[0024] As a preferred solution, after stopping the production line and sounding the alarm, the following steps are also required:

[0025] Use a spare handheld tire pressure device to read the ID information and corresponding tire pressure information of all tires of the current vehicle and upload them.

[0026] As a preferred solution, when the present invention detects that the VIN code of the first vehicle and any of the ID information of the four wheels are inconsistent, if any of the information is detected to be incorrect, the system will stop the assembly line and issue an alarm to prevent faulty vehicles with incorrect VIN codes and tire IDs from flowing into the next process.

[0027] Correspondingly, the application also provides a tire pressure matching error-proof detection device, comprising a trigger detection module, a tire pressure matching detection module and an error-proof detection module.

[0028] The trigger detection module is used to send a trigger signal to an MES system when a first vehicle is detected by a vehicle body detection switch, so that the MES system issues vehicle information of the first vehicle to a tire pressure matching device.

[0030] The error-proof detection module is used to stop the operation of the assembly line and issue an alarm when any of the VIN code of the first vehicle and the ID information of the four wheels does not meet the condition.

[0032] The tire pressure matching detection module controls the antenna plate to send a low-frequency signal to the tire pressure sensor to read the ID information and tire pressure information of the first tire after detecting the first tire by the tire detection switch, only recognizes the low-frequency signal emitted by the tire pressure sensor of the current vehicle, can accurately acquire the tire information of the current vehicle, does not accept the emission signal of the tire pressure sensor of other vehicles on the assembly line, and reduces the tire ID writing error rate caused by the influence of other vehicles on the assembly line.

[0033] The error-proof detection module compares and judges whether any of the vehicle VIN code and the ID information of the four wheels of the vehicle is incorrect after acquiring the vehicle VIN code and the ID information of the four wheels of the vehicle, and further reduces the error rate of writing the vehicle VIN code and the ID information of the four wheels of the vehicle.

[0034] As a preferred solution, the trigger detection module comprises a VIN code calibration unit and a vehicle error-proof detection unit.

[0038] As a preferred solution, the error prevention detection module includes: an ID information error prevention detection unit and a VIN code error prevention detection unit;

[0039] The ID information error-proofing detection unit is used to compare the ID information of the four wheels of the first vehicle with the ID information of the four wheels of the previous N vehicles. If it is detected that the ID information of any tire of the first vehicle is the same as the ID information of any tire of the previous N vehicles, the production line operation is stopped and an alarm is issued.

[0040] The VIN code error-proofing detection unit is used to obtain the VIN code of the current vehicle according to the detection bar code when the vehicle is connected using a wired OBD line and the detection bar code of the current vehicle is scanned, and compare it with the VIN code of the MES system;

[0045] Figure 1 is a flowchart of an embodiment of the error-proof detection method for tire pressure matching provided by the present application;

[0046] Figure 2 is a structural schematic diagram of an embodiment of the error-proof detection device for tire pressure matching provided by the present application. DETAILED DESCRIPTION

[0047] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0048] Embodiment one

[0049] Please refer to Figure 1 The error-proof detection method for tire pressure matching provided by the embodiments of the present application comprises steps S101-S103:

[0050] Step S101: When a vehicle body detection switch detects a first vehicle, a detection trigger signal is sent to the MES system, causing the MES system to transmit the vehicle information of the first vehicle to the tire pressure matching device. The vehicle body detection switch is located in front of the tire pressure matching device, which includes: multiple tire detection switches and multiple antenna panels; the vehicle information includes the VIN code;

[0051] In this embodiment, the tire pressure matching device is installed on the tire pressure matching assembly line. Two body detection switches are respectively installed on the left and right sides in front of the tire pressure matching device on the assembly line. After the vehicle triggers the body detection switch on the assembly line and enters the detection range of the tire pressure matching device, the body detection switch sends a trigger signal to the MES system. The MES system automatically sends the vehicle information to the tire pressure matching device, and the tire pressure matching device starts to enter the matching state.

[0052] In this embodiment, when the vehicle enters the detection range of the tire pressure matching device after triggering the body detection switch, there is no need for employees to scan the vehicle VIN code. The system automatically triggers the MES system to send the vehicle VIN code information through the body detection switch, avoiding tire ID writing errors caused by abnormal employee operations and reducing the tire ID writing error rate.

[0053] In this embodiment, after receiving the VIN code of the first vehicle entering the tire pressure matching device read by the barcode scanner, the VIN codes of the subsequent N vehicles that undergo tire pressure matching are cached in sequence.

[0054] In this embodiment, the detection line barcode of the first vehicle entering the tire pressure matching device is scanned by a barcode scanner to obtain the VIN code of the first vehicle and upload it to the MES system. The MES system contains the production plan information of all vehicles on the assembly line, generates and caches the VIN codes of the N vehicles that will undergo tire pressure matching later. After each vehicle triggers the body detection switch, the MES system automatically issues the vehicle's VIN code.

[0055] The vehicle model queue delivery function implemented in this implementation automatically delivers vehicle information through the MES system. If the MES network fails, the device can use the cached VIN codes of N vehicles to continue tire pressure matching. For vehicles whose VIN codes are not cached in the MES system, the vehicle's VIN code can be manually scanned using a barcode scanner. This reduces the impact of vehicle VIN code writing errors or the inability to write vehicle VIN codes due to MES network failures.

[0056] Step S102: When the tire detection switch detects that the first tire of the first vehicle enters the detection range of the first antenna board, the first antenna board is controlled to transmit a low-frequency signal to a first tire pressure sensor built into the first tire to activate the first tire pressure sensor; based on the transmission signal of the first tire pressure sensor, the tire ID information and tire pressure information read by the first tire pressure sensor are obtained and written to the first vehicle;

[0057] In this embodiment, the first antenna board sends a low-frequency signal to a first tire pressure sensor built into the first tire to activate the first tire pressure sensor, thereby reading the ID information and tire pressure information of the first tire. The first tire pressure sensor marks the ID information and the tire pressure information with a first identification flag. The first tire pressure sensor then transmits the tire pressure information with the first identification flag via a transmission signal.

[0058] The first antenna board determines whether the received first transmission signal carries a first identification flag, and if so, obtains the tire ID information and tire pressure information read by the tire pressure sensor corresponding to the first transmission signal.

[0059] In this embodiment, a first antenna plate is provided on the left side of the assembly line, and a second antenna plate is provided on the right side of the assembly line. The left and right antenna plates are staggered. When a vehicle on the assembly line moves forward, the four tires of the vehicle trigger the first antenna plate and the second antenna plate in the following order: the left front wheel of the vehicle triggers the first antenna plate, the right front wheel of the vehicle triggers the second antenna plate, the left rear wheel of the vehicle triggers the first antenna plate, and the right rear wheel of the vehicle triggers the second antenna plate.

[0060] When a vehicle on the assembly line advances to the position of the first antenna plate on the left side, the first tire detection switch detects the entry of the vehicle's left front wheel. After detecting the trigger signal of the first tire detection switch, the first antenna plate sends a low-frequency signal to the first tire pressure sensor, activating the first tire pressure sensor built into the first tire, so that the first tire pressure sensor reads the ID information and tire pressure information of the left front tire;

[0061] The vehicle continues to move forward, and the second tire detection switch detects the entry of the vehicle's right front wheel. The second antenna board begins to emit a low-frequency signal, activating the second tire pressure sensor built into the second tire, so that the second tire pressure sensor reads the ID information and tire pressure information of the right front tire; and so on, the tire pressure sensors of the vehicle's left front wheel, right front wheel, left rear wheel and right rear wheel are matched in turn, and the tire ID information and tire pressure information are read.

[0062] By adjusting the power of the low-frequency signal emitted by the antenna board and controlling the distance of the low-frequency signal transmission, it is ensured that the antenna board can only activate the tire pressure sensor on the current assembly line and cannot activate the tire pressure sensors on other assembly lines.

[0063] In this embodiment, after the tire pressure sensor reads the ID information and tire pressure information of the four tires of the vehicle, the identification flags of the ID information and tire pressure information of the four tires are marked respectively. For example, the identification flags of the ID information and tire pressure information of the left front wheel, the right front wheel, the left rear wheel and the right rear wheel of the vehicle are marked as: (1001), (2001), (1002) and (2002), respectively.

[0064] The first tire pressure sensor transmits the ID information and tire pressure information with the identification flags (1001) and (1002) via a transmission signal; the second tire pressure sensor transmits the ID information and tire pressure information with the identification flags (2001) and (2002) via a transmission signal;

[0065] The first antenna board and the second antenna board perform flag screening on the received tire pressure information, and filter the ID information and tire pressure information that are not activated by the low-frequency signal. The first antenna board only receives the ID information and tire pressure information with the identification flags (1001) and (1002) activated by the current low-frequency signal, and the second antenna board only receives the ID information and tire pressure information with the identification flags (2001) and (2002) activated by the current low-frequency signal, and saves the identification flags in the historical data record.

[0066] The ID information and tire pressure information sent by the first antenna board and the second antenna board are obtained, and the identification flag of the received first transmission signal is determined. If the identification flag is (1001), the ID information and tire pressure information with the identification flag (1001) are used as the ID information and tire pressure information of the left front wheel of the vehicle, and the ID information and tire pressure information of the four wheels of the vehicle are received in this way.

[0067] This embodiment adds a tire pressure data flag screening function. When performing tire pressure matching on this vehicle, the tire pressure information activated by the low-frequency signal is marked with the first identification flag. Tire pressure information that is not activated by the low-frequency signal, such as tire pressure information automatically sent by the tire pressure sensor, is filtered. Only tire pressure information activated by the current low-frequency signal is received. This can accurately obtain the tire information of the current vehicle and does not accept signals transmitted by tire pressure sensors of other vehicles on the assembly line, thereby reducing the tire ID writing error rate caused by the influence of other vehicles on the assembly line.

[0068] Step S103: When it is detected that any one of the VIN code of the first vehicle and the ID information of the four wheels does not meet the conditions, the operation of the assembly line is stopped and an alarm is issued.

[0069] In this embodiment, the ID information of the four wheels of the first vehicle is compared with the ID information of the four wheels of the previous N vehicles. If it is detected that the ID information of any tire of the first vehicle is the same as the ID information of any tire of the previous N vehicles, the production line operation is stopped and an alarm is issued.

[0070] The current vehicle is connected using a wired OBD line and a detection line barcode of the current vehicle is scanned, a VIN code of the current vehicle is obtained according to the detection line barcode, and the VIN code is compared with a VIN code of the MES system.

[0071] When the VIN code of the current vehicle fails to be compared with the VIN code of the MES system, the operation of the assembly line is stopped, and an alarm is sent.

[0072] The embodiment adds a tire ID error-proof comparison function, after obtaining the ID information of the four wheels of the vehicle, the ID information of the four wheels of the previous N vehicles is compared to determine whether the ID information of the four wheels is incorrect, to avoid tire ID repetition and reduce the error rate of writing the tire ID information.

[0073] The embodiment adds a VIN code error-proof comparison function, an employee scans a detection line barcode, the system automatically performs VIN comparison, and the system automatically writes data to the vehicle after successful comparison; vehicle tire ID writing errors caused by the employee not checking whether the VIN code in the OBD box is consistent with the VIN code of the actual vehicle due to work abnormalities such as absence from work are avoided, and the error rate of writing the VIN code of the vehicle is further reduced.

[0074] In the embodiment, the OBD wire harness can only be pulled to the single-vehicle operation position of the current vehicle post, and the OBD wire cannot be connected to the vehicle position that is not in the post.

[0075] The embodiment upgrades the wireless OBD box to a wired OBD box (fixed length), and the OBD wire harness can only be pulled to the single-vehicle operation of the post, to avoid vehicle tire ID writing errors caused by the employee not checking whether the VIN code in the OBD box is consistent with the VIN code of the actual vehicle due to work abnormalities such as absence from work, and further reduce the error rate of writing the ID information of the four wheels of the vehicle.

[0076] In the embodiment, when it is detected that the ID information of any tire of the first vehicle is different from the ID information of any tire of the previous N vehicles, the current vehicle is connected using a wired OBD line and a detection line barcode of the current vehicle is scanned, a VIN code of the current vehicle is obtained according to the detection line barcode, and the VIN code is compared with a VIN code of the MES system.

[0077] In the embodiment, when the VIN code of the current vehicle is successfully compared with the VIN code of the MES system, the ID information of all the tires and the corresponding tire pressure information read by all the tire pressure sensors are obtained, and the ID information of all the tires and the tire pressure information are written into the BCM of the first vehicle.

[0078] The embodiment adds a system alarm function, directly stops the assembly line through the system, and avoids the flow of faulty vehicles with incorrect tire IDs into the next process.

[0079] In this embodiment, after stopping the operation of the assembly line and issuing an alarm, the following steps are also performed:

[0080] Use a spare handheld tire pressure device to read the ID information and corresponding tire pressure information of all tires of the current vehicle and upload them.

[0081] In this embodiment, after the tire pressure information of all tires is written into the ECU of the first vehicle, the tire pressure sensor's ID, pressure, temperature, standard pressure value, flag, detection time and other information are matched with the vehicle detection line code through the webservice protocol and uploaded to the workshop MES system.

[0082] The implementation of the present invention has the following effects:

[0083] The present invention automatically triggers after detecting the first vehicle through the vehicle body detection switch located in front of the tire pressure matching device. The MES system sends the vehicle information of the first vehicle to the tire pressure matching device, eliminating the need for employees to scan the vehicle VIN code. This reduces the vehicle VIN code matching error rate caused by abnormal employee operations and the tire ID writing error rate.

[0084] After the tire detection switch detects the first tire, the present invention controls the antenna board to send a low-frequency signal to the tire pressure sensor to read the ID information and tire pressure information of the first tire. It only recognizes the low-frequency signal emitted by the tire pressure sensor of the current vehicle, can accurately obtain the tire information of the current vehicle, and does not receive the signals emitted by the tire pressure sensors of other vehicles on the assembly line, thereby reducing the tire ID writing error rate caused by the influence of other vehicles on the assembly line.

[0085] After obtaining the vehicle VIN code and the ID information of the vehicle's four wheels, the present invention performs an error-proof comparison to determine whether any one of the two is incorrect, thereby further reducing the error rate of writing the vehicle VIN code and the ID information of the vehicle's four wheels.

The remaining contents of the present application embodiment can be referenced to the contents of the aforementioned method embodiment and are not further described in this embodiment.

[0100] The implementation of the present invention has the following effects:

[0101] The trigger detection module of the present invention is automatically triggered after detecting the first vehicle through the vehicle body detection switch located in front of the tire pressure matching device. The vehicle information of the first vehicle is sent to the tire pressure matching device by the MES system, eliminating the need for employees to scan the vehicle VIN code, reducing the vehicle VIN code matching error rate caused by employee operation abnormalities and reducing the tire ID writing error rate.

[0102] After the tire pressure matching detection module detects the first tire using the tire detection switch, it controls the antenna board to send a low-frequency signal to the tire pressure sensor to read the ID information and tire pressure information of the first tire. It only recognizes the low-frequency signal transmitted by the tire pressure sensor of the current vehicle, and can accurately obtain the tire information of the current vehicle. It does not receive the signals transmitted by the tire pressure sensors of other vehicles on the assembly line, thereby reducing the tire ID writing error rate caused by the influence of other vehicles on the assembly line.

[0103] After obtaining the vehicle VIN code and the ID information of the vehicle's four wheels, the error detection module of the present invention performs an error comparison to determine whether any of the two is incorrect, thereby further reducing the error rate of writing the vehicle VIN code and the ID information of the vehicle's four wheels.
