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 in FIG. 1 , when the vehicle 100 drives to the reception area 2 along the entrance lane 11 , the service personnel in the reception area 2 will place a positioning tag 21 on the vehicle 100 . , the first positioning tag reader 20 located in the reception area 2 can read (receive) a tag identification code containing the positioning tag 21 emitted by the positioning tag 21 placed on the vehicle 100 the positioning signal, and the first positioning tag reader 20 obtains the tag identification code from the positioning signal, includes the tag identification code and a first identification code in a first positioning signal, and transmits the first positioning signal to the management-side computer 6; and since the management-side computer 6 knows that the first positioning tag reader 20 is located in the reception area 2, when the management-side computer 6 receives the first positioning signal and obtains it from After the first identification code and the label 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 according to the label identification code and the license plate number of the vehicle 100 work record form.

Then, as shown in step S3 of FIG. 1 , the first positioning tag reader 20 will continuously read the positioning signal emitted by the positioning tag 21 on the vehicle 100 staying in the reception area 2 , and continuously transmit the positioning signal. The first positioning signal is sent to the management-side computer 6 until the vehicle 100 leaves the reception area 2, and the management-side computer 6 will start timing after receiving the first positioning signal for the first time. Therefore, the management-side 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 form.

Next, as shown in step S4 in FIG. 1 , when the vehicle 100 enters the work area 3 , the second positioning tag reader 30 located in the work area 3 will read the vehicle 100 entering the work area 3 The positioning signal emitted by the positioning tag 21 on the device, and after obtaining the tag identification code from the positioning signal, a second identification code including 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 end computer 6 , at this time, because the management end computer 6 knows that the second positioning label reader 30 is located in the work area 3 Therefore, the management terminal computer 6 knows that the vehicle 100 has entered the work area 3 according to the tag identification code and the second positioning identification code included in the received second positioning signal and starts to re-time. Therefore, during the period when 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 The second dwell time is in the work record form. In addition, it is worth mentioning that, in order to determine that the vehicle 100 is indeed performing maintenance work in the work area 3 instead of just passing through the work area 3 , when the management computer 6 determines that the vehicle 100 is in the work area 3 for a stop When the time exceeds a preset time, such as 5 minutes, it is determined that the vehicle 100 is indeed performing maintenance work in the work area 3, and the vehicle 100 is continuously counted in the maintenance area 3 according to the continuously received second positioning signal. The second stay time is obtained and recorded in the work record form.

Specifically, as shown in FIG. 2 , the work area 3 also includes a plurality of work parking spaces 31 , and each or several work parking spaces 31 corresponds to a maintenance item, for example, two work parking spaces 31 correspond to the same maintenance item (maintenance item For example, replace the oil and various filter elements, replace the brake pads or tires, clean the throttle oil circuit, replace 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 positioning signal received, determine the orientation and signal strength of the positioning tag 21, and transmit the second positioning signal including the identification code, orientation, signal strength of the positioning tag 21 and the second positioning identification code to the management computer. 6. Make the management terminal computer 6 further calculate which working parking space 31 of the working parking spaces 31 the vehicle 100 is currently in according to the orientation and signal strength of the positioning tag 21, and know which working parking space the vehicle 100 is currently in. maintenance items, and then count a maintenance time that the vehicle 100 stays in the working parking space 31 , whereby, for example, the vehicle 100 needs to perform three maintenance items and stay in three of the working parking spaces 31 in the working area 3 in sequence , the management terminal computer 6 can obtain the second stay time according to the maintenance time of the vehicle 100 in the three working parking spaces 31 respectively, and record the maintenance time of the three working parking spaces 31 and their corresponding of the maintenance item in the work record form.

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

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

Next, as shown in step S5 of FIG. 1 , when the vehicle 100 enters the beauty area 4 , the third positioning tag reader 40 located in the beauty area 4 will receive (read) the The positioning signal emitted by the positioning tag 21 on the vehicle 100, and the tag identification code is obtained from the positioning signal, and then a first identification code including the tag identification code and (the third positioning tag reader 40) itself is included. A third positioning signal of the three-positioning identification code is transmitted to the management-side computer 6, and since the management-side computer 6 has known the location of the beauty area 4 in advance, the management-side computer 6 according to the third positioning signal contains It is known that the vehicle 100 has entered the beauty area 4 and starts to re-time. 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 The third dwell time is in the work record form.

Similarly, it is worth mentioning that, in order to confirm that the vehicle 100 is actually performing cosmetic work in the beauty area 4 instead of just passing through the beauty area 3, when the management computer 6 determines that the vehicle 100 is in the beauty area 4 When the staying time exceeds a preset time, such as 5 minutes, it is determined that the vehicle 100 is indeed performing cosmetic operations in the beauty area 4 , and the vehicle 100 is counted as staying in the beauty area 3 according to the continuously received third positioning signal. The stay time is obtained, and the third stay time is obtained and recorded in the work record form.

Finally, as shown in step S6 of FIG. 1 , after the vehicle 100 completes the beauty treatment in the beauty area 4 , it will drive to the delivery area 5 to prepare for delivery. At this time, similarly, the fourth locating tag reader 50 located in the delivery area 5 will read the locating signal emitted by the locating 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 (the fourth positioning tag reader 50 ) itself is sent to the management terminal computer 6, and since the management-side computer 6 has known the location of the delivery area 5 in advance, the management-side computer 6 according to the label identification code and the fourth positioning identification code contained in the fourth positioning signal, namely It is known that the vehicle 100 has entered the delivery area 5 and the timing is started again. 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 fourth positioning signal continuously transmitted, 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 washing 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 directly go to the delivery area 5 after completing the maintenance operation, so the management terminal computer 6 will not generate and record the third stay time.

In addition, in this embodiment, as shown in FIG. 2 , the vehicle maintenance plant may also plan a dispatch area 9 , and the dispatch area 9 is provided with at least one fifth positioning tag reader electrically coupled to the management terminal computer 6 . and the dispatch area 9 is provided with a plurality of parking bays for the vehicle 100 waiting to enter the work area 3, beauty area 4 or delivery area 5 to pause, and the fifth positioning tag reader 90 will be continuously Read the positioning signal emitted by the positioning tag 21 on the vehicle 100 staying in the dispatch area 9, and obtain the tag identification code from the positioning signal, and then include the tag identification code and (the fifth positioning A fifth positioning signal of a fifth positioning identification code of the tag reader 90) itself is transmitted to the management end computer 6, and since the management end computer 6 has known the location of the dispatch area 9 in advance, the management end computer 6 According to the tag identification code and the fifth positioning identification code included in the fifth positioning signal, the terminal computer 6 knows that the vehicle 100 has entered the dispatch area 9 and starts to re-time. 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 The fifth dwell time is in the work record form.

In addition, it should be further explained that the indoor positioning performed by the positioning tag 21 and the positioning tag readers 20 , 30 , 40 , 50 , 90 and the management terminal computer 6 can be used but not limited to 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.

And after the vehicle 100 waits for the owner to pick up the vehicle 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 make the management 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 in FIG. 1 , when the vehicle 100 drives from the exit lane 12 , the vehicle 100 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 is consistent with the first license plate number, a gate (not shown) located in the exit lane 12 is opened to release the vehicle 100, and A departure time of the vehicle 100 is recorded in the work record form. Of course, the exit lane 12 may directly allow vehicles to pass through without a gate.

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

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 and 32 corresponding to the reception area 2 , the work area 3 , the beauty area 4 and the delivery area 5 respectively. , 42, 52 Through wired or wireless network communication, timely transmit a 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 The terminal electronic devices 22 , 32 , 42 , 52 enable the corresponding persons in charge of the reception area 2 , the work area 3 , the beauty area 4 and the delivery area 5 to be able to pass through the respective terminal electronic devices 22 , 32 of the person in charge. , 42, 52 to 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, it is necessary to set the preset reasonable time of the vehicle in the reception area 2, the work area 3, the beauty area 4 or the delivery area 5 in advance. One of the methods is to estimate based on past maintenance experience, In another method, the management terminal 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, the second stay time and the second 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. Thereby, when the management terminal computer 6 determines that the vehicle 100's stay time 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 is reached, the management terminal computer 6 will promptly send a timeout warning notification to the reception area 2, the work area 3, and the beauty area 4 Or the electronic device 22 , 32 , 42 , 52 of the person in charge corresponding to the delivery area 5 to remind the corresponding person in charge to go to the area in charge to care about or assist in eliminating the problem of backward work progress.

In addition, the management computer 6 can also apply a prediction 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 spaces 31 in the work area 3 and the beauty A load capacity of the area 4 and a first reasonable stay time of the reception area 2, a reasonable maintenance time and a reasonable production capacity of each of the maintenance work spaces 31 in the work area 3, a third reasonable stay in the beauty area 4 time and a reasonable capacity and a fourth reasonable dwell time in the delivery area 5. Specifically, the management terminal computer 6 collects the recorded data such as the work record forms, vehicle maintenance reservation records, vehicle sales records, etc., and provides these data to, for example, the management terminal computer 6 itself or loaded into the management terminal computer 6 itself. A machine learning algorithm in another computer, such as Python Machine Learning Library or AWS Sagemaker, analyzes and learns from the data recorded in the work record forms, vehicle maintenance appointment records, vehicle sales records, etc., and establishes the prediction model.
