[0027] See also Figure 1 , Figure 1 A flow chart of a vehicle dark current test method provided by an embodiment of the present invention. The vehicle dark current test method is applied to a controller of an intelligent terminal, the controller is connected to the vehicle to be tested via a multimeter, and the intelligent terminal can be an electronic device such as a mobile phone, tablet computer, laptop computer, desktop computer, etc.
[0028] Figure 1 The flowchart of the vehicle dark current testing method provided by the embodiment of the present invention is shown in FIG. Figure 1 As shown, the method includes the following steps S110-S140.
[0029] S110, obtaining dark current collection duration and time interval to generate a corresponding dark current data collection signal.
[0030] In this embodiment, the intelligent terminal has a user interface, and the tester can set the dark current collection duration and time interval in the user interface according to the test requirements; specifically, the tester can view the relevant information of the vehicle to be tested in the user interface, select at least one vehicle to be tested according to the test requirements, and then set the dark current collection duration and time interval and other test-related data according to the operating instructions. After the test-related data is set, the controller will generate a corresponding dark current data collection signal according to the acquired dark current collection duration and time interval.
[0031] Furthermore, before conducting a dark current test on the vehicle computer to be tested, it is necessary to ensure that the vehicle computer to be tested is in a non-working state / sleep state. In addition, in order to prevent the power of the vehicle computer to be tested and the multimeter from being too low, resulting in deviations in the test data, it is also necessary to ensure that the vehicle computer to be tested and the multimeter are in normal working condition and that the vehicle computer to be tested and the multimeter are normally connected.
[0032] In one embodiment, before step S110, the method further includes: receiving target Bluetooth broadcast information of the target multimeter; and establishing a Bluetooth connection with the target multimeter according to the target Bluetooth broadcast information.
[0033] In this embodiment, the controller is connected to the target multimeter via Bluetooth. Therefore, before performing a dark current test on the vehicle to be tested, it is necessary to establish a Bluetooth connection between the smart terminal and the target multimeter. Specifically, the software package "Multimeter BLE.apk" can be installed in the smart terminal. After successful installation, the device selection interface of the software is entered. The device selection interface includes at least one Bluetooth broadcast message. The tester can establish a Bluetooth connection with the target multimeter based on the target Bluetooth broadcast message, and then collect the dark current of the target vehicle to be tested associated with the target multimeter through the target multimeter.
[0034] S120. Send the dark current data acquisition signal to the corresponding target multimeter according to the device name in the dark current data acquisition signal, so that the target multimeter acquires the dark current of the target vehicle to be tested according to the received dark current data acquisition signal; wherein the target vehicle to be tested is electrically connected to the target multimeter.
[0035] In this embodiment, the controller can control multiple multimeters at the same time. There is a one-to-one correspondence between the multimeters and the vehicle to be tested. The multimeter is used to collect the dark current of the associated vehicle to be tested. Therefore, the controller sends the dark current data acquisition signal to the corresponding target multimeter according to the device name in the dark current data acquisition signal, so that the target multimeter collects the dark current of the target vehicle to be tested according to the received dark current data acquisition signal; wherein the target vehicle to be tested is electrically connected to the target multimeter, and the device name can be the name of the target multimeter;
[0036] S130, obtaining dark current data returned by the target multimeter based on the dark current data acquisition signal.
[0037] In this embodiment, the dark current data returned by the target multimeter based on the dark current data acquisition signal is obtained; specifically, the dark current data acquisition signal includes test-related data such as dark current acquisition duration and time interval. If the dark current acquisition duration is set to 1 hour and the time interval is set to 1 second, the acquired dark current data includes 3600 current data.
[0038] In one embodiment, after step S130, the method further includes: generating a data acquisition end signal; and sending the data acquisition end signal to the target multimeter, so that the target multimeter emits a corresponding prompt tone according to the received data acquisition end signal.
[0039] In this embodiment, when the controller obtains the dark current data, it indicates that the dark current data collection is completed; after the dark current data collection is completed, a data collection end signal is generated; the data collection end signal is sent to the target multimeter, so that the target multimeter emits a corresponding prompt sound according to the received data collection end signal, prompting the tester that the dark current data collection is completed.
[0040] Furthermore, when the target multimeter is in the data collection state, the Bluetooth icon on the dial is always on, and when the dark current data collection is completed, the Bluetooth icon on the dial is off.
[0041] S140: Analyze the dark current data according to a preset dark current test standard to obtain a test result of whether the target vehicle to be tested passes the dark current test.
[0042] In this embodiment, the dark current standards corresponding to different devices / scenarios are also different. Therefore, it is necessary to analyze the dark current data according to the preset dark current test standard to obtain the test result of whether the target vehicle to be tested passes the dark current test; for example, the dark current average value of the dark current data can be obtained by calculation to determine whether the dark current average value is greater than the dark current standard value in the dark current test standard; if greater than, the test result that the target vehicle to be tested does not pass the dark current test is obtained; if not greater than, the test result that the target vehicle to be tested passes the dark current test is obtained; wherein, the dark current standard value can be set to 9mA or 5mA or 20mA, which can be customized according to the test requirements.
[0043] In one embodiment, step S140 includes: analyzing the dark current data to obtain a corresponding dark current average value; judging whether the dark current average value is greater than a dark current standard value in the dark current test standard to obtain a judgment result; if the judgment result is yes, obtaining a test result that the target vehicle to be tested does not pass the dark current test; if the judgment result is no, obtaining a test result that the target vehicle to be tested passes the dark current test.
[0044] In this embodiment, the dark current data is analyzed to obtain the corresponding dark current average value; for example, the dark current data includes 0.005, 0.004, and 0.006, then the dark current average value of the dark current data is (0.005+0.004+0.006) / 3=0.005; it is determined whether the dark current average value is greater than the dark current standard value in the dark current test standard to obtain a judgment result; if the judgment result is yes, a test result is obtained that the target vehicle to be tested does not pass the dark current test; if the judgment result is no, a test result is obtained that the target vehicle to be tested passes the dark current test.
[0045] In one embodiment, after analyzing the dark current data to obtain the corresponding dark current average value, it also includes: obtaining the maximum value and the minimum value of the dark current data; determining whether the maximum value and the minimum value are within the dark current standard range in the dark current test standard; if the maximum value or the minimum value is not within the dark current standard range, generating a corresponding error message.
[0046] In this embodiment, the maximum value and the minimum value of the dark current data are obtained; it is determined whether the maximum value and the minimum value are within the dark current standard range of the dark current test standard; if the maximum value or the minimum value is not within the dark current standard range, a corresponding error message is generated; the error message is sent to the corresponding relevant tester according to the preset contact information; the error message includes the error content and the time when the error content occurs. Specifically, the error message may be "At 12:33:28 on January 1, during the dark current test of the vehicle 001 to be tested, large current fluctuations occurred". The relevant testers can locate the fault in time according to the received error information.
[0047] Furthermore, in order to intuitively view the dark current fluctuation, the tester can set the coordinate axis format in the software with the line graph generation function to generate a line graph corresponding to the dark current data; wherein the coordinate axis format includes the coordinate axis boundary and the coordinate axis ordinate unit.
[0048] In one embodiment, before step S140, it also includes: determining whether the data type of the dark current data is a digital type to obtain a data type determination result; if the data type determination result is no, converting the numerical value in the dark current data into a digital type numerical value to obtain the converted dark current data.
[0049] In this embodiment, the data type of the acquired dark current data may not be a digital type. If it is not a digital type, errors may occur in the process of calculating the dark current data. Therefore, it is necessary to determine whether the data type of the dark current data is a digital type and obtain a data type judgment result. If the data type judgment result is no, the numerical value in the dark current data is converted into a numerical value of a digital type to obtain the converted dark current data, and then, the converted dark current data is analyzed according to the preset dark current test standard to obtain the test result of whether the target vehicle to be tested passes the dark current test. If the data type judgment result is yes, the dark current data is analyzed according to the preset dark current test standard to obtain the test result of whether the target vehicle to be tested passes the dark current test.
[0050] In summary, the embodiment of the present invention can control the multimeter to automatically collect the dark current of the vehicle to be tested through the intelligent terminal, without the need for manual dark current testing, which can effectively reduce the cost of manual testing and improve the efficiency and accuracy of dark current testing.
