Before the present invention is described in detail, it should be noted that in the following description, similar elements are denoted by the same numbers.

Referring to FIG. 1, it is an embodiment of the intelligent management method of the vehicle repair and maintenance process of the present invention, which is applied to a vehicle maintenance plant as shown in FIG. A working area 3, a beauty area 4 and a delivery area 5, and the entry and exit passage 1, the reception area 2, the work area 3, the beauty area 4 and the delivery area 5 are only for the location, sequence and movement The schematic diagram for the convenience of explanation is not the actual field design. The method of this embodiment is implemented by a vehicle maintenance process intelligent management system installed in the vehicle maintenance factory shown in FIG. 2. An embodiment of the vehicle maintenance process intelligent management system includes a management terminal computer 6. A first image capturing device 7 arranged in the access channel 1 and electrically coupled to the management terminal computer 6, and a first positioning tag arranged in the reception area 2 and electrically coupled to the management terminal computer 6 Reader 20, a second positioning tag reader 30 that is provided in the work area 3 and electrically coupled to the management terminal computer 6, and a second location tag reader 30 that is provided in the beauty area 4 and electrically coupled to the management terminal computer 6 The third location tag reader 40, a fourth location tag reader 50 that is provided in the delivery area 5 and is electrically coupled to the management terminal computer 6, and a fourth location tag reader 50 that is provided in the access passage 1 and is connected to the management terminal computer 6 The second image capturing device 8 electrically coupled. The term "electrical coupling" mentioned above refers to devices that can communicate through wired connections (such as signal lines or network cables) or wireless transmission methods (such as short-range wireless communications) to transmit signals. The management terminal computer 6 is set in the reception area 2 as an example, but not limited to this, that is, the management terminal computer 6 may also be located in other areas of the vehicle maintenance factory.

Moreover, the management terminal computer 6 knows where the first positioning tag reader 20, the second positioning tag reader 30, the third positioning tag reader 40, and the fourth positioning tag reader 50 are located. . In addition, the number of the first positioning tag reader 20, the second positioning tag reader 30, the third positioning tag reader 40, and the fourth positioning tag reader 50 is not limited to one. , But according to the size of the field set and the range of the received signal to determine the number of settings.

In addition, the entry and exit passage 1 can be a single-lane two-way lane or a two-lane one-way lane in actual implementation. Figure 2 is an example of a two-lane one-way lane, that is, the entry and exit passage 1 is planned to include an entrance lane 11 And an exit lane 12, and the first image capturing device 7 is set in an appropriate position of the entrance lane 11 to capture license plate images of vehicles entering from the entry lane 11, and the second image capturing device 8 It is set at an appropriate position of the exit lane 12 to capture the license plate image of the vehicle about to leave the exit lane 12. In addition, if the entry and exit passage 1 is a single-lane two-way lane, the first image capturing device 7 and the second image capturing device 8 will be set in the appropriate positions of the lane to capture the entering lane and the upcoming lane respectively. Image of the license plate of the leaving vehicle.

Furthermore, when there are no vehicles entering or exiting the passage 1, the first image capturing device 7 and the second image capturing device 8 will not capture images all the time but are in a standby state. Therefore, in order to trigger a camera in the first image capturing device 7 and the second image capturing device 8 to act in a timely manner to capture (shoot) the license plate image of the vehicle, the first image capturing device 7 and the second image capturing device 8 The two image capturing devices 8 also include a proximity (proximity) sensor (not shown) (not shown in the figure) that is arranged at the entrance lane 11 and the exit lane 12 at appropriate positions. When the proximity sensor detects When an object is detected approaching, a trigger signal is sent to trigger the action of the camera.

Therefore, with the above-mentioned devices installed in the vehicle maintenance shop, as shown in step S1 of FIG. The first image capturing device 7 in the entrance lane 11 captures a first license plate image of the vehicle 100 entering from the entrance lane 11, and transmits the first license plate image to the management terminal computer 6, the After receiving the first license plate image, the management terminal computer 6 performs image recognition on the first license plate image to obtain a first license plate number of the vehicle 100, and records the first license plate number and an entry of the vehicle 100 time. At this time, the management terminal computer 6 can also confirm whether the vehicle 100 is a reserved vehicle according to the first license plate number.

Next, as shown in step S2 of FIG. 1, when the vehicle 100 drives along the entrance lane 11 to the reception area 2, the service staff in the reception area 2 will place a positioning tag 21 on the vehicle 100. , The first location tag reader 20 provided in the reception area 2 can read (receive) a tag identification code containing the location tag 21 emitted by the location tag 21 placed on the vehicle 100 And the first positioning tag reader 20 obtains the tag identification code from the positioning signal, and after including the tag identification code and a first identification code in a first positioning signal, transmits the first positioning signal Signal to the management terminal computer 6; and since the management terminal computer 6 knows that the first location tag reader 20 is located in the reception area 2, when the management terminal computer 6 receives the first location signal and obtains it After the first identification code and the tag identification code, it is known that the vehicle 100 is currently located in the reception area 2, and a record of the entry time of the vehicle 100 is established based on the tag identification code and the license plate number of the vehicle 100 Work record form.

Then, in step S3 of FIG. 1, the first location tag reader 20 will continuously read the location signal emitted by the location tag 21 on the vehicle 100 staying in the reception area 2, and continuously transmit the location signal The first positioning signal is given to the management terminal computer 6 until the vehicle 100 leaves the reception area 2, and the management terminal computer 6 will start timing after receiving the first positioning signal for the first time. Therefore, the management terminal computer 6 That is, a first stay time of the vehicle 100 in the reception area 2 can be calculated according to the continuously transmitted first positioning signal, and the first stay time can be recorded in the work record sheet.

Next, as shown in step S4 in Fig. 1, when the vehicle 100 enters the work area 3, the second location tag reader 30 provided in the work area 3 will read the vehicle 100 entering the work area 3 The positioning signal transmitted by the positioning tag 21 on the locator, and after obtaining the tag identification code from the positioning signal, a second identification code containing the tag identification code and (the second positioning tag reader 30) itself is generated. Locate the second positioning signal of the identification code, and transmit the second positioning signal to the management terminal computer 6. At this time, since the management terminal computer 6 knows that the second positioning tag reader 30 is located in the work area 3 Therefore, the management terminal computer 6 knows that the vehicle 100 has entered the working area 3 and starts to re-time according to the tag identification code and the second location identification code contained in the received second positioning signal. Therefore, while the vehicle 100 stays in the work area 3, the management terminal computer 6 can calculate a second stay time of the vehicle 100 in the work area 2 according to the continuously transmitted second positioning signal, and record it The second stay time is in the work record form. In addition, it is worth mentioning that, in order to determine that the vehicle 100 does maintenance work in the work area 3 instead of just passing through the work area 3, when the management terminal computer 6 determines that the vehicle 100 is staying in the work area 3 When the time exceeds a preset time, for example, 5 minutes, it is determined that the vehicle 100 is indeed performing maintenance operations in the work area 3, and the vehicle 100 is kept in the repair area 3 according to the continuously received second positioning signal. The second stay time is obtained and recorded in the work record sheet.

Specifically, as shown in Figure 2, the work area 3 also includes a plurality of work parking spaces 31, each or several work parking spaces 31 corresponding to a certain maintenance item, for example, two work parking spaces 31 correspond to the same maintenance item (maintenance item For example, replacing engine oil and various filter elements, replacing brake pads or tires, cleaning the throttle oil circuit, replacing the battery, etc.), and in the above step S4, the second positioning tag reader 30 can also transmit according to the positioning tag 21 The received positioning signal determines the position and signal strength of the positioning tag 21, and transmits the second positioning signal including the identification code, position, signal strength and the second positioning identification code of the positioning tag 21 to the management terminal computer 6. Make the management terminal computer 6 further calculate which of the working parking spaces 31 of the working parking spaces 31 the vehicle 100 is currently based on the position of the positioning tag 21 and the signal strength, and know which one of the working parking spaces 31 the vehicle 100 is currently in. Maintenance items, and then calculate a maintenance time of the vehicle 100 staying in the working parking space 31, by which, for example, the vehicle 100 needs to perform three maintenance items and sequentially staying in three of the working parking spaces 31 of the working area 3 , The management terminal computer 6 can calculate the second stay time according to the maintenance time of the vehicle 100 in the three working parking spaces 31, and respectively record the maintenance time of the three working parking spaces 31 and its corresponding The maintenance items of this are listed in the work record sheet.

Of course, in order to further improve the positioning accuracy of the vehicle 100 in each working parking space 31 of the working area 3, a plurality of second positioning tag readers 30 scattered in different positions can be arranged in the working area 3. Then the management The end computer 6 can use the second positioning signals including the different signal strengths of the positioning tags 21 from the plurality of second positioning tag readers 30 to more accurately calculate the working parking space where the vehicle 100 is located. 31.

In addition, it is worth mentioning that, in order to determine that the vehicle 100 does have maintenance operations in the work area 3 instead of just passing through the work area 3, when the management terminal computer 6 determines that the vehicle 100 is in at least one of the work areas 3. When the maintenance time of the working parking space 31 exceeds, for example, 5 minutes, it is determined that the vehicle 100 has at least one maintenance item, and the total maintenance time, maintenance items, and corresponding maintenance personnel of the vehicle 100 in the at least one working parking space 31 are determined and / Or manpower, etc. are recorded in the work record form.

Then, in step S5 of FIG. 1, when the vehicle 100 enters the beauty area 4, the third positioning tag reader 40 provided in the beauty area 4 will receive (read) the The positioning signal transmitted by the positioning tag 21 on the vehicle 100, and the identification code of the tag is obtained from the positioning signal, and then the identification code of the tag and (the third positioning tag reader 40) itself are included. A third positioning signal with three positioning identification codes is sent to the management end computer 6, and since the management end computer 6 has known the location of the beauty area 4 in advance, the management end computer 6 includes The tag identification code and the third location identification code of, it is known that the vehicle 100 has entered the beauty area 4 and restarts the timing. Therefore, while the vehicle 100 stays in the beauty area 4, the management terminal computer 6 can calculate a third stay time of the vehicle 100 in the beauty area 4 according to the continuously transmitted third positioning signal, and record it The third stay time is in the work record form.

Similarly, it is worth mentioning that in order to determine that the vehicle 100 is indeed performing beauty operations in the beauty area 4 instead of just passing through the beauty area 3, when the management terminal computer 6 determines that the vehicle 100 is in the beauty area 4 Once the stay time exceeds a preset time, for example, 5 minutes, it is determined that the vehicle 100 is indeed performing beauty operations in the beauty area 4, and the vehicle 100 is staying in the beauty area 3 according to the continuously received third positioning signal. To obtain the third residence time and record it in the work record sheet.

Finally, as shown in step S6 in Fig. 1, when the vehicle 100 completes the beauty project in the beauty area 4, it immediately drives to the vehicle delivery area 5 to prepare for delivery of the vehicle. At this time, similarly, the fourth positioning tag reader 50 provided in the delivery area 5 will read the positioning signal emitted by the positioning tag 21 on the vehicle 100 staying in the delivery area 50, and After extracting the tag identification code from the positioning signal, a fourth positioning signal including the tag identification code and a fourth positioning identification code of (the fourth positioning tag reader 50) itself is sent to the management terminal Computer 6, and since the management terminal computer 6 has known the location of the delivery area 5 in advance, the management terminal computer 6 according to the tag identification code and the fourth positioning identification code contained in the fourth positioning signal, namely It is learned that the vehicle 100 has entered the delivery area 5 and starts to re-timing. Therefore, while the vehicle 100 stays in the delivery area 4, the management terminal computer 6 can calculate a fourth stay time of the vehicle 100 in the delivery area 5 according to the continuously transmitted fourth positioning signal. And record the fourth stay time in the work record form. In addition, the vehicle 100 may also go directly from the reception area 2 to the beauty area 4 for car wash and beauty, so the management terminal computer 6 will not generate and record the second stay time, or the vehicle 100 may also be in the work area 3 After completing the maintenance work, go directly to the delivery area 5, so the management terminal computer 6 will not generate and record the third stay time.

In addition, in this embodiment, as shown in Figure 2, the vehicle maintenance plant can also plan a dispatch area 9 in which at least one fifth location tag reader electrically coupled to the management terminal computer 6 is provided. And the dispatching area 9 is provided with multiple parking spaces for the vehicle 100 waiting to enter the work area 3, the beauty area 4 or the delivery area 5 to pause, and the fifth positioning tag reader 90 will continue Read the positioning signal transmitted by the positioning tag 21 on the vehicle 100 in the dispatch area 9, and obtain the tag identification code from the positioning signal, and then include the tag identification code and its (the fifth positioning) A fifth positioning signal of a fifth positioning identification code of the tag reader 90) is transmitted to the management computer 6, and since the management computer 6 has known the location of the dispatch area 9 in advance, the management According to the tag identification code and the fifth location identification code included in the fifth positioning signal, the terminal computer 6 knows that the vehicle 100 has entered the dispatching area 9 and starts to restart the timing. Therefore, while the vehicle 100 stays in the dispatch area 9, the management terminal computer 6 can calculate a fifth stay time of the vehicle 100 in the dispatch area 9 according to the continuously transmitted fifth positioning signal, and record it The fifth stay time is in the work record form.

In addition, it should be further explained that the indoor positioning performed by the above-mentioned positioning tag 21 and the positioning tag readers 20, 30, 40, 50, 90 and the management terminal computer 6 can be but not limited to The existing Bluetooth BLE indoor positioning technology, indoor WiFi positioning technology, radio frequency identification (RFID) indoor positioning technology, Zigbee indoor positioning, ultra-wideband (UWB) positioning technology, infrared indoor positioning technology, etc. are realized.

And after the vehicle 100 waits for the owner to pick up the car in the delivery area 5 and completes the checkout operation, the service personnel in the delivery area 5 remove the positioning tag 21 from the vehicle 100 and instruct the management terminal computer 6 When the timing is stopped, the management terminal computer 6 calculates the fourth stay time of the vehicle 100 in the delivery area 5 according to the fourth positioning signal transmitted for the first time and the last time. Then, the vehicle owner can drive out of the delivery area 4 and drive toward the exit lane 12. At this time, as shown in step S7 of FIG. 1, when the vehicle 100 leaves the exit lane 12, it is set in the exit lane 12 The second image capturing device 8 captures a second license plate image of the vehicle 100 and transmits the second license plate image to the management end computer 6, and the management end computer 6 performs image recognition on the second license plate image to obtain A second license plate number, and after confirming (comparing) that the second license plate number matches the first license plate number, a gate (not shown) in the exit lane 12 is opened to release the vehicle 100, and Record a departure time of the vehicle 100 in the work record sheet. Of course, the exit lane 12 can also directly allow vehicles to pass without a gate.

Thereby, the management terminal computer 6 can calculate a total service time of the vehicle 100 according to the time of entering the factory and the time of leaving the factory of the vehicle 100 and record it in the work record sheet.

In addition, as shown in FIG. 3, the management terminal computer 6 can also communicate with a plurality of person-in-charge terminal devices 22, 32 respectively corresponding to the reception area 2, the work area 3, the beauty area 4, and the delivery area 5. , 42, 52, through wired or wireless network communication, timely transmit the stay time of the vehicle 100 in the reception area 2, the work area 3, the beauty area 4 or the delivery area 5 to the corresponding person in charge Terminal electronic devices 22, 32, 42, 52, so that the respective responsible persons of the reception area 2, the work area 3, the beauty area 4, and the delivery area 5 can use the respective responsible persons’ terminal electronic devices 22, 32 , 42, 52 know the current maintenance progress of the vehicle 100, and whether the stay time of the vehicle 100 in the reception area 2, the work area 3, the beauty area 4 or the delivery area 5 has exceeded a preset Reasonable time.

Specifically, the preset reasonable time for the vehicle in the reception area 2, the work area 3, the beauty area 4, or the delivery area 5 should be set in advance. One method is to estimate based on past maintenance experience. In another method, the management computer 6 can collect the work record forms recorded in the past (for example, two years ago to the present), and statistically analyze the first stay time and the second stay time recorded in the work record forms. Stay time, the third stay time, and the fourth stay time to obtain a first reasonable stay time corresponding to the reception area 2, a second reasonable stay time corresponding to the work area 3, and the beauty A third reasonable stay time corresponding to the area 4 and a fourth reasonable stay time corresponding to the delivery area 5. Thus, when the management terminal computer 6 determines that the stay time of the vehicle 100 in the reception area 2, the work area 3, the beauty area 4, or the delivery area 5 has exceeded the corresponding first reasonable stay time, When the second reasonable stay time, the third reasonable stay time, or the fourth reasonable stay time, the management terminal computer 6 will promptly send an overtime warning notice to the reception area 2, the work area 3, and the beauty area 4 Or the person-in-charge electronic device 22, 32, 42, 52 corresponding to the delivery area 5 to remind the corresponding person-in-charge to go to the area in charge to care about or help eliminate the problem of backward work progress.

In addition, the management terminal computer 6 can also apply a predictive model established by machine learning to predict the number of vehicles that will be returned to the factory for maintenance in the next few days, a load of each of the work parking spaces 31 in the work area 3, and the beauty A load of area 4 and a first reasonable stay time of the reception area 2, a reasonable maintenance time and a reasonable capacity of each of the maintenance work parking spaces 31 of the work area 3, and a third reasonable stay of the beauty area 4 Time and a reasonable production capacity and a fourth reasonable stay time in the delivery zone 5. Specifically, the management terminal computer 6 collects the recorded work record forms, vehicle maintenance appointment records, vehicle sales records, and other data, and provides these data to be loaded in the management terminal computer 6 itself or loaded in, for example, A machine learning algorithm in another computer, such as Python Machine Learning Library or AWS Sagemaker, enables analysis and learning based on the data recorded in the work record forms, vehicle maintenance appointment records, vehicle sales records, etc., and establishes the Forecast model. Since the use of machine learning to build a predictive model for a specific purpose is a well-known and mature technology, and is not the main technical focus of this case, it will not be detailed here.

Therefore, when the management terminal computer 6 determines that the stay time of the vehicle 100 in the reception area 2, a certain working parking space 31 of the work area 3, the beauty area 4 or the delivery area 5 has exceeded the corresponding When the first reasonable stay time, the reasonable maintenance time, the third reasonable stay time or the fourth reasonable stay time, the management terminal computer 6 will promptly send an overtime warning notification to the reception area 2, the work area 3.
