As shown in fig. 1, the method for testing a shift display panel includes the following steps:
s110, obtaining a test feedback signal of the target test gear shifting display panel in a preset test scene.
The target test gear shifting display panel represents a gear shifting display panel needing to be tested. The preset test scene represents a preset scene for testing different functional modules of the target test shift display panel, and the preset test scene may include multiple types, for example, the preset test scene may include a working voltage test scene, a communication voltage test scene, a local interconnection network communication function test scene, a lighting function test scene, a sleep and wake-up function test scene, and an internal LED lamp fault detection function test scene, and is used for testing multiple functions of the target test shift display panel.
The test feedback signal represents a working signal of the target test panel in a test scene, and can reflect the test function condition of the target test shift display panel. Whether various test functions of the target test shift display panel are abnormal or not can be determined through the test feedback signal. For example, whether the target test shift display panel can work normally can be reflected by judging whether a test feedback signal can be received or whether the signal value of the test feedback signal is normal, and the form of the test feedback signal can be adjusted adaptively according to different test scenes. Further, the target test shift display panel can send the test feedback signal to the upper computer, so that the test feedback signal of the target test shift display panel in a preset test scene is obtained.
And S120, determining a test result of the target test shift display panel under the preset test scene according to the test feedback signal, and completing a test process.
The test result indicates a result of whether the test function of the target test shift display panel is normal, specifically, a test feedback signal of the target test shift display panel may be compared with a preset reference feedback signal, and when the test feedback signal is the same as the preset reference feedback signal or a difference between the test feedback signal and the preset reference feedback signal is smaller than a preset reference error threshold, it may be determined that the test function of the target test shift display panel in a preset test scene is normal; conversely, when the test feedback signal is different from the preset reference feedback signal, or the difference between the test feedback signal and the preset reference feedback signal is not less than the preset reference error threshold, it may be determined that the test function of the target test shift display panel in the preset test scene is abnormal.
According to the technical scheme provided by the embodiment of the invention, a test feedback signal of the target test gear-shifting display panel in a preset test scene is obtained; and determining a test result of the target test shift display panel in a preset test scene according to the test feedback signal, and completing the test process. The technical scheme of the embodiment of the invention solves the problem that the internal function and the fault diagnosis function of the gear shifting display panel cannot be independently tested in the prior art, and can independently test the internal function and the fault diagnosis function of the gear shifting display panel and shorten the test period of the gear shifting display panel.
Fig. 2 is a flowchart of a method for testing a shift display panel according to an embodiment of the present invention, where the embodiment of the present invention is applicable to a scenario of testing a function of a shift display panel, and on the basis of the above embodiment, the present embodiment further illustrates a preparation operation performed before obtaining a test feedback signal, and how to determine a test result of a target test shift display panel in a preset test scenario according to the test feedback signal.
As shown in fig. 2, the method for testing the shift display panel includes the following steps:
s210, sending a test scene trigger signal under a preset test scene to the target test gear-shifting display panel.
The target test shift display panel represents a shift display panel that needs to be tested. The preset test scene represents a preset scene for testing different functional modules of the target test shift display panel, and the preset test scene may include multiple types, for example, the preset test scene may include a lighting function test scene and a sleep and wake-up function test scene for testing the lighting function and the sleep and wake-up function of the target test shift display panel.
The test scene trigger signal represents a signal for triggering the function of the target test shift display panel in the preset test scene, the test scene trigger signal corresponds to the preset test scene, and the test scene trigger signal corresponding to the preset test scene can be sent in different types of preset test scenes for testing the function of the target test shift display panel in the preset test scene. Specifically, a test scene trigger signal can be sent to the target test shift display panel through the upper computer, and the function of the target test shift display panel under a preset test scene is tested.
For example, when the preset test scenario is a light-on function test scenario, an engine start signal, a gear signal of each vehicle and an engine off signal may be sent to the target test shift display panel at least once under the preset panel power supply voltage value.
The preset panel power supply voltage represents a preset voltage for supplying power to the target test gear shifting display panel, the preset panel power supply voltage needs to be taken within a preset conventional power supply voltage interval, and when the preset panel power supply voltage is taken within the preset conventional power supply voltage interval, the light lighting function of the target test gear shifting display panel cannot be affected. The engine starting signal is used for starting a light lighting function of the target test gear-shifting display panel, the driving gear signal comprises gear signals such as a backlight lamp gear signal, a parking gear signal, a reverse gear signal, a neutral gear signal and a forward gear signal, the light lighting function test condition of the target test gear-shifting display panel is fed back, and the engine extinguishing signal is used for closing the light lighting function of the target test gear-shifting display panel. By sending an engine starting signal, a gear signal of each vehicle and an engine extinguishing signal to the target test gear shift display panel, whether the function of each vehicle gear of the lighting power of the target test gear shift display panel is normal can be tested.
Further, when the preset test scene is a sleep and wake-up function test scene, a preset sleep simulation signal can be sent to the target test shift display panel when the panel power supply voltage is within a preset conventional power supply voltage interval; when the panel power supply voltage is within a preset abnormal power supply voltage interval and a fault signal of the target test gear shifting display panel is obtained, sending a sleep simulation signal to the target test gear shifting display panel; and when the test feedback signal of the target test gear shifting display panel is not received any more, sending a preset awakening signal to the target test gear shifting display panel.
The preset conventional power supply voltage interval represents a preset power supply voltage interval which can enable the target test shift display panel to normally work, and correspondingly, when the power supply voltage is in the abnormal power supply voltage interval, the target test shift display panel cannot normally work; the preset sleep analog signal represents a preset analog signal which can enable the target test shift display panel to enter a sleep mode; the fault signal represents a signal that the target test gear shifting display panel detects that the power supply voltage is abnormal; the preset wake-up signal represents a preset analog signal that can wake up the target test shift display panel from the sleep mode. Specifically, the upper computer can be used for sending a preset sleep analog signal and a preset wake-up signal to the target test shift display panel and receiving a fault signal sent by the target test shift display panel.
S220, obtaining a test feedback signal of the target test gear shifting display panel in a preset test scene.
The test feedback signal represents a working signal of the target test panel in a test scene, and can reflect the test function condition of the target test shift display panel. Whether various test functions of the target test shift display panel are abnormal or not can be determined through the test feedback signal. For example, whether the target test shift display panel can work normally can be reflected by judging whether a test feedback signal can be received or whether the signal value of the test feedback signal is normal, and the form of the test feedback signal can be adjusted adaptively according to different test scenes. Further, the target test shift display panel can send the test feedback signal to the upper computer, so that the test feedback signal of the target test shift display panel in a preset test scene is obtained.
And S230, comparing the test feedback signal with a reference feedback signal under the preset test scene.
The reference feedback signal represents a preset signal for judging whether the test function of the target test shift display panel is normal, specifically, the test feedback signal of the target test shift display panel can be compared with the reference feedback signal, and if the test feedback signal is the same as the reference feedback signal or the difference between the test feedback signal and the reference feedback signal is smaller than a preset reference error threshold, it can be determined that the test function of the target test shift display panel in a preset test scene is normal; on the contrary, if the test feedback signal is different from the reference feedback signal, or the difference between the test feedback signal and the reference feedback signal is not less than the preset reference error threshold, it may be determined that the test function of the target test shift display panel in the preset test scene is abnormal.
For example, when the preset test scene is a lamplight lighting function test scene, the reference feedback signal under the lamplight lighting function test scene is compared with the test feedback signal, and when the reference feedback signal and the test feedback signal are the same, it can be determined that the lamplight lighting function of the target test shift display panel is normal, otherwise, the lamplight lighting function is abnormal.
When the preset test scene is a sleep and wake-up function test scene, if the target test shift display panel enters a sleep mode after receiving the preset sleep analog signal, and meanwhile, if the voltage abnormality is detected before the preset sleep analog signal is received, the voltage fault diagnosis can be carried out again after the target test shift display panel is waken up from the sleep mode, the sleep and wake-up functions of the target test shift display panel can be determined to be normal, otherwise, the sleep and wake-up functions are abnormal.
S240, determining a function test result of the target test shift display panel under the preset test scene according to the comparison result.
If the test feedback signal is the same as the reference feedback signal or the difference value between the test feedback signal and the reference feedback signal is smaller than a preset reference error threshold value, determining that the function test result of the target test shift display panel in the preset test scene is normal; on the contrary, if the test feedback signal is different from the reference feedback signal, or the difference between the test feedback signal and the reference feedback signal is smaller than the preset reference error threshold, it may be determined that the function test result of the target test shift display panel in the preset test scene is abnormal.
In an optional implementation manner, when the test feedback signal indicates that an abnormal condition occurs, a test log for recording a preset time length may be started, and the preset time length is recorded for the test feedback signal of the target test shift display panel in a preset test scene, so that the abnormal function of the target test shift display panel may be conveniently processed in the following. For example, when the preset test scenario is a sleep and wake-up function test scenario, if the target test shift display panel does not enter the sleep mode after receiving the preset sleep simulation signal, a log for 10 seconds is recorded, and the log content can be analyzed subsequently, which is helpful for finding a fault.

The technical scheme of the embodiment of the invention solves the problem that the internal function and the fault diagnosis function of the gear shifting display panel cannot be independently tested in the prior art, and can be independently tested, thereby shortening the test period of the gear shifting display panel.

The test upper computer is used for obtaining a test feedback signal of the gear shifting display panel to be tested in a preset test scene, determining a test result of the gear shifting display panel to be tested in the preset test scene according to the test feedback signal, and completing a test process. The test upper computer comprises analog signal simulation software and feedback signal acquisition software, the analog signal simulation software is used for generating a test scene trigger signal in a preset test scene and sending the test scene trigger signal to the target test shift display panel, the feedback signal acquisition software is used for acquiring a test feedback signal of the target test shift display panel in the preset test scene, comparing the test feedback signal with a reference feedback signal in the preset test scene, and determining a function test result of the target test shift display panel in the preset test scene according to the comparison result.
The shift display panel to be tested is a tested object and is connected with the test upper computer and used for generating a target test feedback signal.
The power supply subsystem is connected with the gear shifting display panel to be tested and provides electric energy for the gear shifting display panel to be tested, and the power supply subsystem can also provide voltages with different voltage values for the gear shifting display panel to be tested and is used for testing the functions of the gear shifting display panel to be tested.
The work flow of the gear shifting display panel testing system is as follows: the method comprises the steps that a test upper computer obtains a test feedback signal of a gear shifting display panel to be tested in a preset test scene; and determining a test result of the gear shifting display panel to be tested in a preset test scene according to the test feedback signal, and completing the test process. Specifically, when the preset test scene is a light lighting function test scene or a sleep and wake-up function test scene, before the test feedback signal of the gear-shifting display panel to be tested is obtained, the upper computer can send a test scene trigger signal to the gear-shifting display panel to be tested. In addition, when the power supply voltage of the gear shifting display panel to be tested needs to be adjusted, the power supply voltage of the gear shifting display panel to be tested can be adjusted through the power subsystem, the gear shifting display panel to be tested sends a test feedback signal under a preset test scene to the test upper computer, and the test result of the gear shifting display panel to be tested under the preset test scene is determined by the upper computer according to the test feedback signal.
For example, when the preset test scenario is a light-on function test scenario, an engine start signal, a gear signal of each vehicle and an engine off signal may be sent to the target test shift display panel at least once under the value of the preset panel power supply voltage.
When the preset test scene is a sleep and wake-up function test scene, a preset sleep simulation signal can be sent to the target test shift display panel when the panel power supply voltage is within a preset conventional power supply voltage interval; when the power supply voltage of the panel is within a preset abnormal power supply voltage interval and a fault signal of the target test gear-shifting display panel is obtained, sending a sleep simulation signal to the target test gear-shifting display panel; and when the test feedback signal of the target test gear shifting display panel is not received any more, sending a preset awakening signal to the target test gear shifting display panel.
When the preset test scene is a voltage test scene, voltages with different voltage values can be provided for the target test gear-shifting display panel, and whether the function of detecting abnormal working voltage of the target test gear-shifting display panel is normal or not is detected. When the preset test scene is a communication voltage test scene, voltages with different voltage values can be provided for the target test shift display panel, and whether the upper limit value and the lower limit value of the communication voltage value of the target test shift display panel are normal or not is observed. When the preset test scene is a local interconnection network communication function test scene, whether the local interconnection network communication function of the target test shift display panel is normal or not can be determined by disconnecting and connecting the communication line and observing whether a gear lamp on the target test shift display panel is lightened or not. When the preset test scene is an internal LED lamp fault detection function test scene, whether the target test gear-shifting display panel sends a fault signal or not is judged through opening or short-circuiting an LED circuit inside the target test gear-shifting display panel, and whether the internal LED lamp fault detection function of the target test gear-shifting display panel is normal or not is determined.
Correspondingly, when the preset test scene is the lamplight lighting function test scene, the reference feedback signal under the lamplight lighting function test scene is compared with the test feedback signal, when the reference feedback signal and the test feedback signal are the same, the lamplight lighting function of the target test gear-shifting display panel can be determined to be normal, and otherwise, the lamplight lighting function is abnormal.
When the preset test scene is a sleep and wake-up function test scene, if the target test shift display panel enters a sleep mode after receiving a preset sleep analog signal, and meanwhile, if the voltage abnormity is detected before the preset sleep analog signal is received, the voltage fault diagnosis can be carried out again after the target test shift display panel is waken up from the sleep mode, the sleep and wake-up function of the target test shift display panel can be determined to be normal, otherwise, the sleep and wake-up function is abnormal.
When the preset test scene is a voltage test scene, if the target test shift display panel can detect a voltage fault and send a fault signal when the power supply voltage is in an abnormal power supply voltage interval, the fault voltage detection function of the target test shift display panel can be determined to be normal, otherwise, the fault voltage detection function is abnormal.
When the preset test scene is a communication voltage test scene, if the difference value between the upper limit value of the communication voltage of the target test shift display panel and the preset reference communication voltage and the difference value between the lower limit value of the communication voltage of the target test shift display panel and the preset reference communication voltage are smaller than the preset reference error threshold value, it can be determined that the communication voltage of the target test shift display panel is normal, otherwise, the communication voltage is abnormal.
When the preset test scene is a local interconnection network communication function test scene, if the gear lamp on the target test shift display panel is turned off after the communication line is disconnected and the gear lamp is turned on again after the communication line is connected, it can be determined that the local interconnection network communication function of the target test shift display panel is normal, otherwise, the local interconnection network communication function is abnormal.
When the preset test scene is an internal LED lamp fault detection function test scene, if an LED circuit inside the target test gear-shifting display panel is open or short-circuited, the target test gear-shifting display panel can send a fault signal, and then the internal LED lamp fault detection function of the target test gear-shifting display panel can be determined to be normal, otherwise, the internal LED lamp fault detection function is abnormal.
According to the technical scheme provided by the embodiment of the invention, a test upper computer is used for acquiring a test feedback signal of the shift display panel to be tested in a preset test scene; and determining a test result of the gear shifting display panel to be tested in a preset test scene according to the test feedback signal, and completing the test process.
