[0030] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein.

[0031] Figure 1 FIG. 2 shows a schematic diagram of the structure of the alcohol interlock device provided by the present invention. Figure 1 As shown, the alcohol interlock device 100 includes an alcohol lock 101 and a vehicle computer 102. Before starting the vehicle, the alcohol lock can detect the alcohol content in the driver's breath and display the detection result on the vehicle computer. The vehicle computer can determine whether to start the vehicle based on the detection result, thereby using the alcohol interlock device to ensure driving safety.

[0032] Currently, testing of alcohol interlock devices is mostly done manually, resulting in low testing efficiency.

[0033] In view of this, the present application proposes a testing method for an alcohol interlock device, which can automatically test the alcohol interlock device, obtain test results, and improve test efficiency.

[0034] Figure 2 FIG. 2 shows a schematic diagram of the structure of a first embodiment of a test system provided by the present invention. Figure 2 As shown, the test system 200 includes a host computer 201, an alcohol gas generator 202, and an alcohol interlock device 203 to be tested.

[0035] The host computer 201 is connected to the alcohol gas generator 202 and the alcohol interlock device 203 to be tested respectively.

[0036] The host computer 201 is used to monitor, manage and process test data. The host computer can be an electronic device with processing capabilities, such as a computer or a laptop computer.

[0037] The alcohol gas generator 202 is used to generate alcohol gas. It should be noted that the embodiment of the present invention does not limit how the alcohol gas generator generates alcohol gas. For example, the alcohol gas may be generated by heating liquid alcohol.

[0038] The alcohol interlock device to be tested 203 is an alcohol interlock device to be tested. The embodiment of the present invention does not limit the type of alcohol lock and the type of vehicle computer included in the alcohol interlock device to be tested.

[0039] It should be noted that the embodiment of the present invention does not limit the connection method between the host computer and the alcohol gas generator and the alcohol interlock device to be tested. For example, it can be a wired communication connection or a wireless communication connection.

[0040] In this way, the alcohol gas generator in the test system can simulate the driver's blowing behavior, and then the alcohol interlock device to be tested can detect the alcohol gas generated by the alcohol gas generator. The host computer can determine the test result of the alcohol interlock device to be tested based on the test result received from the alcohol interlock device to be tested.

[0041] In some embodiments, reference Figure 3 As shown, Figure 3 FIG. 2 shows a schematic diagram of the structure of a second embodiment of the test system provided by the present invention. Figure 3 As shown, the alcohol interlock device 203 to be tested includes an alcohol lock 2031 to be tested; the test system 200 also includes a drive structure 204 , the drive structure 204 is connected to the host computer 201 , and the alcohol lock 2031 to be tested is arranged on the drive structure 204 .

[0042] The alcohol lock to be tested 2031 represents the alcohol lock to be tested.

[0043] The driving structure 204 is used to drive the alcohol lock to be tested to move, that is, the driving structure can control the distance between the alcohol gas generator 202 and the alcohol lock 2031 to be tested. In this way, the blowing distance between the driver and the alcohol lock can be simulated.

[0044] Optionally, the driving structure 204 may include a driving motor 2041 and a screw structure 2042; the driving motor 2041 is connected to the host computer 201, the driving motor 2041 and the screw structure 2042 are movably connected, and the alcohol lock 2031 to be tested is fixedly arranged on the screw structure 2042. In this way, the host computer can control the motor to drive the screw structure to move, thereby driving the alcohol lock to be tested to move.

[0045] In this way, the alcohol gas generator can simulate the driver's blowing behavior, and the driving structure drives the alcohol lock to be tested to move, which can simulate the blowing distance between the driver and the alcohol lock, thereby more accurately simulating the driver's blowing process into the alcohol lock and improving the accuracy of the test.

[0046] In some embodiments, reference Figure 4 As shown, Figure 4 FIG. 2 shows a schematic diagram of the structure of the third embodiment of the test system provided by the present invention. Figure 4 As shown, the alcohol interlock device 203 to be tested includes an alcohol lock 2031 to be tested and a vehicle computer 2032 to be tested; the test system 200 also includes a terminal block 205, a power supply 206, a collection device 207 and a bus collection device 208; the terminal block 205 is respectively connected to the alcohol lock 2031 to be tested, the vehicle computer 2032 to be tested, the bus collection device 208, and the power supply 206; the bus collection device 208 is connected to the host computer 201; and the collection device 207 is connected to the host computer 201.

[0047] The vehicle computer to be tested 2032 represents the vehicle computer to be tested.

[0048] The terminal block 205 is an electrical connection device that can connect multiple circuits together to facilitate circuit wiring and management.

[0049] The power supply 206 is used to supply power to the equipment of the test system. It should be noted that the embodiment of the present invention does not limit the type of the power supply. By connecting the power supply to the terminal block, the equipment connected to the terminal block can be supplied with power.

[0050] The acquisition device 207 is used to acquire information generated by the vehicle to be tested. The acquisition device can be an image acquisition device, such as a camera or a webcam or other electronic device with an image acquisition function; or an audio acquisition device, such as a microphone or other electronic device with a recording function. The embodiment of the present invention does not limit the type of acquisition device, and it can be set according to actual needs.

[0051] The bus acquisition device 208 is used to acquire information transmitted in the bus.

[0052] In this way, the alcohol interlock device to be tested and the bus acquisition device are connected by using a terminal block, which makes it easy to replace the alcohol interlock device to be tested. In other words, when replacing the alcohol interlock device to be tested, it is only necessary to connect the updated alcohol interlock device to be tested to the terminal block, without changing other equipment in the test system, thereby improving the test efficiency.

[0053] In some embodiments, in order to ensure the accuracy of the test, the test system may also include some supporting equipment, such as an operating table, for placing the alcohol gas generator and the drive structure to ensure the stability of the alcohol lock to be tested, thereby ensuring the accuracy of the test results generated by the alcohol lock to be tested, thereby improving the accuracy of the test results. The supporting equipment may also include a dark box for placing the vehicle machine to be tested and the acquisition device to ensure the accuracy of the feedback information collected by the acquisition device, thereby improving the accuracy of the test results.

[0054] Figure 5 The flowchart of the first embodiment of the test method of the alcohol interlock device provided by the present invention is shown, and the method is executed by the host computer. Figure 2 and Figure 5 As shown, the method comprises the following steps:

[0055] S301. Send a first control signal to an alcohol gas generator.

[0056] Exemplarily, the first control signal is used to trigger the alcohol gas generator to generate alcohol gas.

[0057] In some possible implementations, the host computer may generate a first control signal according to a preset test case and send the first control signal to the alcohol gas generator. The preset test case may indicate the alcohol content, and the alcohol gas generator may generate alcohol gas according to the first control signal.

[0058] S302, obtaining actual test results of the alcohol interlock device to be tested.

[0059] Exemplarily, the above actual detection result represents the detection result of the alcohol interlock device to be tested on the alcohol gas generated by the alcohol gas generator. It should be understood that the vehicle to be tested in the alcohol interlock device to be tested needs to determine the detection result of the vehicle to be tested based on the detection result of the alcohol lock to be tested. Therefore, the actual detection result may include only the detection result generated by the vehicle to be tested, or may include the detection result generated by the alcohol lock to be tested and the detection result generated by the vehicle to be tested. The embodiment of the present invention is not limited here.

[0060] In some possible implementations, the host computer can obtain the test results generated by the vehicle computer to be tested in the alcohol interlock device to be tested to obtain the actual test results. For example, the test results generated by the vehicle computer to be tested can be sent directly to the host computer, or the test results generated by the vehicle computer to be tested can be collected by a collection device and then sent to the host computer; or the host computer can obtain the test results generated by the alcohol lock to be tested in the alcohol interlock device to be tested to obtain the actual test results. For example, the host computer can use a bus collection device to collect information sent by the alcohol lock to be tested to the vehicle computer to be tested to obtain the actual test result.

[0061] S303: Determine the test result of the alcohol interlock device to be tested according to the actual test result.

[0062] Exemplarily, the above test results indicate whether the alcohol interlock device to be tested functions normally.

[0063] In some possible implementations, as mentioned above, the host computer can generate a first control signal according to a test case, and the test case corresponds to a theoretical test result, in other words, a correct test result under the test case. Therefore, after obtaining the actual test result, the host computer can compare the actual test result with the theoretical test result. If the two are determined to be consistent, it means that the function of the alcohol interlock device to be tested is normal, and the test of the alcohol interlock device to be tested is determined to have passed; if the two are determined to be inconsistent, it means that the function of the alcohol interlock device to be tested is abnormal, and the test of the alcohol interlock device to be tested is determined to have failed.

[0064] In this embodiment, based on a test system including a host computer, an alcohol interlock device to be tested, and an alcohol gas generator, the host computer can automatically control the alcohol gas generator to produce alcohol gas, and then obtain the actual detection result of the alcohol interlock device to be tested on the alcohol gas, and determine the test result of the alcohol interlock device to be tested based on the actual detection result. In this way, the host computer can automatically test the alcohol interlock device to be tested, obtain the test result, and improve the test efficiency.

[0065] Figure 6 The flowchart of the second embodiment of the alcohol interlock device testing method provided by the present invention is shown, and the method is executed by the host computer. Figure 4 and Figure 6 As shown, the method comprises the following steps:

[0066] S401. Generate a first control signal according to a preset test case.

[0067] Exemplarily, the preset test case represents the driver's blowing scenario, which may include, for example: a. driver blowing hard, b. driver blowing softly, c. driver stopping blowing early, d. driver blowing at a long distance to the alcohol lock, e. driver blowing at a close distance to the alcohol lock, f. driver effective distance and effective blowing time scenario, etc. It should be noted that the embodiment of the present invention does not limit the content of the test case, and the above is only an illustration.

[0068] Optionally, the test case may indicate gas emission information, which includes one or more of the following: gas content, gas concentration, and gas emission duration. The gas content represents the total amount of alcohol gas generated, the gas concentration represents the alcohol concentration in the generated alcohol gas, and the gas emission duration represents the duration of generating alcohol gas. The gas emission information may also include blowing strength, for example, soft blowing and strong blowing.

[0069] The first control signal may indicate the information of the gas emission. It should be noted that the embodiment of the present invention does not limit the form of the first control signal, which is specifically related to the setting of the alcohol gas generator, for example, it may be a pulse width modulation (PWM) signal.

[0070] In some possible implementations, the above-mentioned preset test cases may be pre-stored in a host computer, or may be acquired by the host computer through communication with other electronic devices. Optionally, a test case library may be preset in the host computer, and the test case library includes multiple test cases. For example, Table 1 is a schematic diagram of a test case library provided in an embodiment of the present invention.

[0071] Table 1 Test case library

[0072] Serial number Gas content Gas concentration Gas emission time Test Case 1 Content 1 Concentration 1 Duration 1 Test Case 2 Content 2 Concentration 2 Duration 2 Test case 3 Content 3 Concentration 3 Duration 3

[0073] In some possible implementations, the host computer may randomly determine a test case as the test case for the alcohol interlock device to be tested, and then generate a first control signal according to the test case. Alternatively, the host computer may receive a test case specified by a user, and generate a first control signal according to the specified test case. Alternatively, the host computer may test the alcohol interlock device to be tested in sequence according to all test cases in the test case library, and generate a first control signal corresponding to each test case in sequence according to each test case.

[0074] S402: Send a first control signal to the alcohol gas generator.

[0075] Exemplarily, the host computer may send the first control signal to the alcohol gas generator.

[0076] Optionally, the alcohol gas generator can generate corresponding alcohol gas according to the first control signal. For example, the alcohol gas generator can include a controller, and the controller can adjust the temperature of the heating element based on the first control signal so that the liquid alcohol evaporates to generate alcohol gas. It should be noted that the embodiment of the present invention does not limit how to generate alcohol gas.

[0077] Optionally, after the alcohol gas generator generates alcohol gas, the alcohol interlock device to be tested can generate a detection result based on the alcohol gas.

[0078] S403: Receive detection information sent by the bus acquisition device.

[0079] Exemplarily, the above detection information represents the information generated by the alcohol lock to be tested. The detection information may include, for example, the authentication result of the alcohol lock, the current working status information of the alcohol lock, the remaining time for the alcohol lock to be disabled and restored, etc.; wherein, the authentication result of the alcohol lock represents whether the alcohol lock can be powered on, and the authentication result may include authentication success, authentication failure, and pending authentication, etc. The current working status information of the alcohol lock represents the current state of the alcohol lock, and may include, for example, normal state, initial test state, retest state, analysis state, error state, locked state, etc. The remaining time for the alcohol lock to be disabled and restored represents the time required to wait for retesting after the alcohol lock is locked.

[0080] In some possible implementations, as mentioned above, the alcohol lock to be tested can detect alcohol gas, and then generate detection information, and send it to the vehicle to be tested through the bus, so that the vehicle to be tested determines whether the vehicle can be started based on the detection information. Therefore, the host computer can collect the detection information on the bus based on the bus acquisition device and receive the detection information sent by the bus acquisition device.

[0081] S404: Receive feedback information sent by the collection device.

[0082] Exemplarily, the above feedback information represents the information generated by the vehicle computer to be tested and collected by the collection device. Optionally, the vehicle computer to be tested can generate prompt information based on the detection information sent by the alcohol lock to be tested, and the prompt information corresponds to the detection information one by one. The prompt information can be, for example, text information displayed on the vehicle computer to be tested, or it can be output voice information. Therefore, the collection device can take a picture of the text information displayed on the vehicle computer to be tested, obtain a picture, that is, the feedback information, and send it to the host computer; or the collection device can collect the voice information output by the vehicle computer to be tested, obtain audio, that is, the feedback information, and send it to the host computer.

[0083] For example, Table 2 is a schematic diagram of detection information and feedback information provided by an embodiment of the present invention. It should be noted that the embodiment of the present invention does not limit the content of the detection information and feedback information, and Table 2 is only a schematic diagram.

[0084] Table 2 Detection information and feedback information

[0085]

[0086]

[0087] S405. Determine the test result of the alcohol interlock device to be tested according to the actual test result and the theoretical test result corresponding to the preset test case.

[0088] Exemplarily, the above theoretical detection structure represents the correct detection result generated by the alcohol interlock device under the test case. Optionally, the theoretical detection result may include theoretical feedback information and theoretical detection information, wherein the theoretical feedback information represents the correct information that the vehicle under test should generate under the test case, and the theoretical detection information represents the correct information that the alcohol interlock device under the test case should generate under the test case.

[0089] The above-mentioned preset test cases have a one-to-one correspondence with the theoretical detection results, and the theoretical detection results can be obtained together when the test cases are obtained. For example, a test case library can be preset in the host computer, and the test case library can include test cases and theoretical detection results corresponding to the test cases. For example, Table 3 is a schematic diagram of another test case library provided in an embodiment of the present invention.

[0090] Table 3 Test case library

[0091] Serial number Gas content Gas concentration Gas emission time Theoretical test results Test Case 1 Content 1 Concentration 1 Duration 1 Result 1 Test Case 2 Content 2 Concentration 2 Duration 2 Result 2 Test case 3 Content 3 Concentration 3 Duration 3 Result 3

[0092] Therefore, the host computer can determine the theoretical test result corresponding to the test case based on the test case used this time, and then compare the actual test result with the theoretical test result corresponding to the test case to determine the test result of the alcohol interlock device to be tested.

[0093] Specifically, this step may include the following steps:

[0094] S4051. Determine the test result of the vehicle computer to be tested according to the feedback information and the theoretical feedback information.

[0095] In a possible implementation, if the feedback information is a picture, the host computer can determine the first eigenvector of the picture and the second eigenvector of the theoretical feedback information according to a preset detection model, and then determine the similarity between the first eigenvector and the second eigenvector. If the similarity is greater than or equal to a preset threshold, the two are determined to be consistent, and the function of the vehicle to be tested is determined to be normal; if the similarity is less than the preset threshold, the two are determined to be inconsistent, and the function of the vehicle to be tested is determined to be abnormal. The detection model can be, for example, a convolutional neural network model, which is not limited in the embodiments of the present invention.

[0096] Alternatively, a comparison model is preset in the host computer, and the pictures in the feedback information and the pictures in the theoretical feedback information are input into the comparison model together, and a comparison result is output. The comparison result is used to characterize the similarity between the feedback information and the theoretical feedback information. If the comparison result indicates that the two are consistent, it is determined that the function of the vehicle computer to be tested is normal, otherwise.

[0097] In another possible implementation, if the feedback information is audio, the host computer can determine the third eigenvector in the audio of the feedback information and the fourth eigenvector of the theoretical feedback information, and then determine the similarity between the third eigenvector and the fourth eigenvector. If the similarity is greater than or equal to a preset threshold, the two are determined to be consistent, and the function of the vehicle machine to be tested is determined to be normal; if the similarity is less than the preset threshold, the two are determined to be inconsistent, and the function of the vehicle machine to be tested is determined to be abnormal.

[0098] S4052: Determine the test result of the alcohol lock to be tested according to the test information and theoretical test information.

[0099] Exemplarily, the detection information may be collected in the form of a signal, so the host computer may compare whether the signal of the detection information is consistent with the signal of the theoretical detection information. If they are consistent, it is determined that the function of the alcohol lock to be tested is normal; if they are inconsistent, it is determined that the function of the alcohol lock to be tested is abnormal.

[0100] S4053. Determine the test result of the alcohol interlock device to be tested according to the test result of the vehicle computer to be tested and the test result of the alcohol lock to be tested.

[0101] Exemplarily, if the upper computer determines that the function of the vehicle to be tested and the function of the alcohol lock to be tested are both normal, then it is determined that the function of the alcohol interlock device to be tested is normal, that is, the alcohol interlock device to be tested passes the test; if it is determined that there is a functional abnormality in either, then it is determined that the function of the alcohol interlock device to be tested is abnormal, that is, the alcohol interlock device to be tested fails the test.

[0102] In this embodiment, the host computer can generate a first control signal based on the test case to control the alcohol gas generator to generate alcohol gas, and then determine the test result of the alcohol interlock device to be tested according to the received detection information and feedback information, as well as the theoretical detection result corresponding to the test case. In this way, the host computer can control the alcohol gas generator to simulate the driver's blowing behavior, and automatically collect the detection results, and then compare them with the theoretical detection results to obtain the test results, thereby intelligently implementing the test of the alcohol interlock device and improving the test efficiency.

[0103] Figure 7The flowchart of the third embodiment of the test method of the alcohol interlock device provided by the present invention is shown, and the method is executed by the host computer. Figure 4 and Figure 7 As shown, the method comprises the following steps:

[0104] S501. Generate a second control signal according to a preset test case.

[0105] Exemplarily, the above-mentioned preset test case can indicate the moving distance of the driving structure, and the second control signal is used to trigger the driving structure to move. Optionally, the driving structure can include a driving motor and a screw structure; the driving motor is movably connected to the screw structure, and the alcohol lock to be tested is fixedly arranged on the screw structure; therefore, the second control signal can indicate the moving distance of the screw structure relative to the driving motor.

[0106] In a possible implementation, the preset test case includes the moving distance. For example, Table 4 is a schematic diagram of another test case library provided by an embodiment of the present invention. The host computer may generate a second control signal based on the test case.

[0107] Table 4 Test case library

[0108]

[0109] S502: Send a second control signal to the driving structure.

[0110] Exemplarily, the host computer can send the second control signal to the motor of the drive structure, so that the motor drives the screw structure to move the alcohol lock to be tested based on the second control signal to simulate the blowing distance when the driver blows into the alcohol lock.

[0111] S503: Generate a first control signal according to a preset test case.

[0112] It should be noted that this step is similar to step S401 and will not be described again here.

[0113] S504: Send a first control signal to the alcohol gas generator.

[0114] It should be noted that this step is similar to step S402 and will not be described again here.

[0115] S505: Receive detection information sent by the bus acquisition device.

[0116] It should be noted that this step is similar to step S403 and will not be repeated here.

[0117] S506: Receive feedback information sent by the collection device.

[0118] It should be noted that this step is similar to step S404 and will not be repeated here.

[0119] S507: Determine the test result of the vehicle computer to be tested according to the feedback information and the theoretical feedback information.

[0120] It should be noted that this step is similar to step S4051 and will not be repeated here.

[0121] S508: Determine the test result of the alcohol lock to be tested according to the test information and the theoretical test information.

[0122] It should be noted that this step is similar to step S4052 and will not be repeated here.

[0123] S509: Determine the test result of the alcohol interlock device to be tested according to the test result of the vehicle computer to be tested and the test result of the alcohol lock to be tested.
