It should be understood that the devices with the controllers installed connected to the testing device 2 can be referred to as computing platforms 3 to be tested, and the testing method of each computing platform 3 to be tested is the same. It should be noted that the controller is installed inside the computing platform 3, and it can be known whether the controller installed inside the computing platform 3 can be used normally through the performance problem result fed back by the computing platform 3. The controller may be a controller, and the controller may be a master device for controlling the starting, speed regulation, braking and reversing of the motor by changing the wiring of the master circuit or the control circuit and changing the resistance value in the circuit according to a predetermined sequence, and comprises a program counter, an instruction register, an instruction decoder, a timing generator and an operation controller.

Specifically, the testing device 2 may be understood as a device that can be detachably connected to a plurality of computing platforms 3 to be tested, and can perform data exchange and data processing with the computing platforms 3 to be tested, so as to test performance problems of the computing platforms 3 to be tested, in order to facilitate displaying a performance problem result of the computing platforms 3 to be tested, in some feasible implementation manners, the testing device 2 and the display 1 may be integrated, and in other feasible implementation manners, the testing device 2 is connected to the external display 1. As for the connection mode between the testing device 2 and the computing platform 3 to be tested, in some feasible implementation modes, the testing device 2 and the computing platform 3 to be tested are connected by a wired connection mode, specifically, the testing device 2 is provided with a plurality of USB (Universal Serial Bus) interfaces, and is connected by a wired connection with the computing platform 3 to be tested by the USB interfaces, in other feasible implementation modes, the testing device 2 and the computing platform 3 to be tested are connected wirelessly, considering that the wired connection has high reliability and is not easily interfered by an external environment, therefore, the computing platform 3 to be tested and the testing device 2 are preferably connected by a wired connection.
In one embodiment, the test task may further include information of a test start time, a time interval between two adjacent tests, and the like. It should be understood that the user sets the test tasks through the test task setting page displayed on the display 1.
The working principle of the testing device of the unmanned vehicle computing platform 3 provided by the embodiment is as follows:
a user configures a test task on a display 1, then starts the test task, so that a test device 2 receives the test task, a first test is performed at the moment, the test device 2 issues a command to a power controller 4, the power controller 4 controls a power supply 5 to supply power to a computing platform 3 to be tested and cut off the power to complete a first test, then the computing platform 3 to be tested feeds a performance problem result back to the test device 2 after the power is supplied, the test device 2 transmits the performance problem result to the display 1 to be displayed, then the test device 2 records the completed test times, when the completed test times are different from the test times in the test task, a second test is performed according to the same test method until the completed test times are the same as the test times in the test task.
The testing device for the unmanned vehicle computing platform 3 provided by the embodiment at least has the following technical effects:
the power supply 5 is controlled repeatedly to supply power and cut off power to the computing platform 3 to be tested according to the test times, so that the test equipment 2 obtains a performance problem result fed back by the computing platform 3 to be tested, the simulation controller is installed on the working condition inside the computing platform 3, the quality test of the controller inside the computing platform 3 is realized, the controller passing the quality test is used, and the probability of problems occurring in the later-stage use of the controller is reduced.
In one embodiment, the computing platform to be tested 3 comprises an autonomous driving computing unit, a parallel driving system and/or a car networking system. It should be noted that, the embodiment is not intended to limit the computing platform 3 to be tested, and the specific requirement needs to be determined in combination with actual requirements.
In one embodiment, the performance issues include: whether camera initialization is normal, whether CAN (Controller Area Network, ISO international standardized serial communication protocol) communication is normal and/or whether Network communication is normal. It should be noted that, the embodiment is not intended to limit the performance problem, and the specific requirement needs to be determined in combination with actual requirements.
In one embodiment, the test device 2 issues a command to the power controller 4 by way of a General-purpose input/output (GPIO). It should be noted that, this embodiment is not intended to limit the method for issuing a command to the power controller 4 by the test device 2, and the determination needs to be specifically determined in combination with actual requirements.
In one embodiment, the testing apparatus counts the respective repetition times of the different performance problem results of the computing platform 3 to be tested, and outputs the respective repetition times of the different performance problem results to the display 1 for displaying, so that a user can conveniently analyze whether the controller in the computing platform 3 can be normally used according to the success times and the failure times of the different performance problem results.
In this embodiment, the quality test of the controller in the computing platform 3 to be tested is realized by counting the repetition times of different performance test results of the computing platform 3 to be tested and comprehensively considering the overall performance of the computing platform 3 to be tested in multiple tests, and the controller passing the quality test is used, so that the probability of problems occurring in the later-stage use of the controller is reduced. For example, the computing platform 3 to be tested has a performance problem result, and there are two different performance problem results: the CAN communication is normal, the CAN communication is abnormal, the number of times of repetition of the CAN communication is normal is a1, the number of times of repetition of the CAN communication is abnormal is a2, and a1+ a2= A.
It will be appreciated that the test results displayed by the display 1 include performance problem results and the number of repetitions of the performance problem results.
In one embodiment, the computing platform to be tested 3 feeds back a start result to the testing device 2 after power supply; and the test equipment 2 receives the performance problem result fed back by the computing platform 3 to be tested when judging that the computing platform 3 to be tested is started normally based on the starting result fed back by the computing platform 3 to be tested.
In this embodiment, the computing platform 3 to be tested feeds back a start result to the testing device 2 after power supply, the testing device 2 determines whether the computing platform 3 to be tested starts normally based on the start result fed back by the computing platform 3 to be tested, and receives a performance problem result fed back by the computing platform 3 to be tested when it is determined that the computing platform 3 to be tested starts normally, thereby ensuring accuracy of the performance test result, when it is determined that the computing platform 3 to be tested starts abnormally, it is not necessary to receive the performance problem result fed back by the computing platform 3 to be tested, and it is only necessary to directly determine that the computing platform 3 to be tested starts abnormally, thereby rapidly implementing testing of the computing platform 3 to be tested. It will be appreciated that the performance test results have a relatively high reference value due to the consideration of the start-up of the computing platform 3 to be tested.
It is to be noted that after the testing device 2 starts the computing platform 3 to be tested, the computing platform 3 to be tested performs a start self-check to obtain a start result of itself, specifically, a number or a letter may be used to represent a normal start and an abnormal start, for example, 1 and 0 are set, 1 represents a normal start, and 0 represents an abnormal start, and then the computing platform 3 to be tested sends the start result and the device identifier to the testing device 2, so that the testing device 2 obtains the start result and the device identifier fed back by the computing platform 3 to be tested. If the testing device 2 is wired to the computing platform 3 to be tested, the device identifier may be a product identifier.
In an embodiment, when the testing device 2 determines that the computing platform 3 to be tested is not in the flashing mode, the testing device executes the starting result fed back based on the computing platform 3 to be tested, and when it determines that the computing platform 3 to be tested is started normally, receives the performance problem result fed back by the computing platform 3 to be tested.
It should be noted that, considering that the computing platform 3 to be tested may have a flashing mode, at this time, the testing device 2 needs to verify whether the computing platform 3 to be tested is in the flashing mode, when the testing device 2 determines that the computing platform 3 to be tested is not in the flashing mode, the testing device will perform the operation of receiving the performance problem result fed back by the computing platform 3 to be tested when determining that the start result is normal, and if the testing device 2 determines that the computing platform 3 to be tested is in the flashing mode, the display 1 may be controlled to display the device identifier of the computing platform 3 to be tested in the flashing mode, so that the user can know the computing platform 3 in the flashing mode.
In one embodiment, the testing device 2 is detachably connected with at least two computing platforms 3 to be tested; when the test equipment 2 receives a test task, the test equipment 2 issues a command to the power controller 4, so that the power controller 4 controls the power supply 5 to supply power to and cut off power from the at least two computing platforms 3 to be tested.
In this embodiment, when there are two or more to-be-tested computing platforms 3 connected to the testing device 2, the testing device 2 can control the power supply 5 to simultaneously supply power to and cut off power from the two or more to-be-tested computing platforms 3, thereby performing batch testing and improving testing efficiency.
When there are two or more to-be-tested computing platforms 3 connected to the testing device 2, in one embodiment, the testing device 2 determines the number of normal starting platforms according to the starting results fed back by the at least two to-be-tested computing platforms 3 respectively; when the number of the normal starting platforms is different from the number of the at least two to-be-tested computing platforms 3, the testing device 2 judges whether each to-be-tested computing platform 3 is started normally; and when the number of the normal starting platforms is the same as that of the at least two computing platforms 3 to be tested, the testing equipment 2 judges that the starting of each computing platform 3 to be tested is normal.
In this embodiment, the comparison between the number of platforms of all the computing platforms 3 to be tested controlled by the testing device 2 and the number of normal starting platforms in all the computing platforms 3 to be tested preliminarily determines whether the computing platforms 3 to be tested start normally, and subsequently, when the computing platforms 3 to be tested start normally, the computing platforms 3 to be tested perform performance testing, determine a performance problem result and feed the performance problem result back to the testing device 2, and the obtained performance problem result takes into account the overall starting condition of all the computing platforms 3 to be tested controlled by the testing device 2, thereby having a relatively high reference value.
It can be understood that the number of platforms indicates the number of computing platforms 3 to be tested that the testing device 2 controls in one test, and in practical applications, the testing device 2 will generally control all computing platforms 3 to be tested that are connected to it, so that what number of computing platforms 3 to be tested the testing device 2 is connected to is what number of platforms. The number of normal boot platforms indicates the number of computing platforms 3 to be tested that the testing device 2 normally boots up among all computing platforms 3 to be tested controlled in one test.
It is noted that whether the number of platforms is equal to the number of normal startup platforms reflects the overall startup situation of all the computing platforms 3 to be tested that are controlled by the testing device 2 in one test. In a possible situation, when the number of the platforms detected by the testing device 2 is consistent with the number of the normal starting platforms, it can be considered that each computing platform 3 to be tested is normally started at this time, and after the testing device 2 judges that the computing platforms 3 to be tested are normally started, the computing platforms 3 to be tested verify the performance problem, so as to obtain a performance problem result. In another possible situation, when the number of platforms detected by the testing device 2 is inconsistent with the number of normally started platforms, it is necessary to determine whether each computing platform 3 to be tested is normally started, so as to ensure the accuracy of the test.
In one embodiment, the testing device 2 and the at least two computing platforms to be tested 3 are wired; when the number of the normal starting platforms is different from the number of the at least two to-be-tested computing platforms 3, the testing device 2 performs network verification on the to-be-tested computing platforms 3 based on the internet protocol addresses of the to-be-tested computing platforms 3; the testing device 2 judges that the computing platform 3 to be tested is normally started when the network verification of the computing platform 3 to be tested passes, and judges that the computing platform 3 to be tested is abnormally started when the network verification fails.
Considering that the reliability of the wired method is high, when the number of the platforms is different from the number of the normal startup platforms, part of the computing platforms 3 to be tested may not be normally started, and certainly, an interface between the computing platforms 3 to be tested and the testing device 2 may have a problem, in order to more accurately determine whether the computing platforms 3 to be tested are normally started, at this time, it is necessary to further verify whether each computing platform 3 to be tested is normally started, and optionally, for each computing platform 3 to be tested, the starting condition of the computing platform 3 to be tested is verified through a network, so as to ensure the accuracy of the performance test result of the obtained computing platform 3 to be tested.
Specifically, the network verification of the computing platform 3 to be tested is realized by acquiring an internet protocol address, i.e. an IP address, of the computing platform 3 to be tested according to the internet protocol address through a network verification instruction, such as ping, and when the network verification of the computing platform 3 to be tested passes, it indicates that the computing platform 3 to be tested starts normally, and when the network verification of the computing platform 3 to be tested does not pass, it indicates that the computing platform 3 to be tested starts abnormally. It should be noted that the network verification method of each computing platform 3 to be tested is consistent, and in practical application, the testing device 2 performs network verification on all computing platforms 3 to be tested at the same time.
Referring to fig. 2, a specific application scenario is given as follows:
one measuring device is provided with N USB interfaces, the measuring device is in wired connection with N computing platforms 3 to be tested in a USB interface mode, the N computing platforms 3 to be tested are in one-to-one correspondence with the N USB interfaces, the N computing platforms 3 to be tested are respectively provided with an IP address, and the measuring device is connected with a display 1 so that a user can set a test task through the display 1, wherein the test task is as follows: the test frequency is 10000, the performance problem includes whether the camera initialization is normal, whether the CAN communication is normal and/or whether the network communication is normal, the time interval between any two tests is t, and the test equipment 2 repeatedly sends a command to the power supply controller 4 connected with the test equipment according to the test task, so that the power supply controller 4 controls the power supply 5 connected with the power supply controller to continuously supply power to and cut off power from the N computing platforms 3 to be tested for 10000 times, namely, the power supply and the power off of the N computing platforms 3 to be tested are carried out in each test.
In practical application, for each computing platform 3 to be tested in each test, when the testing device 2 judges that the computing platform 3 to be tested is not in the flashing mode, the testing device can receive a starting result and a device identifier fed back by the computing platform 3 to be tested, wherein the starting result comprises 1 or 0, wherein 1 represents normal starting, and 0 represents abnormal starting; when the test device 2 receives the device identifiers of the N computing platforms 3 to be tested, it may be determined that the number of platforms of all the computing platforms 3 to be tested in the current test is N. Of course, if the computing platform 3 to be tested does not have the feedback device identifier, or the device identifier is the product identifier of the USB interface, the number of platforms N is directly determined by the number of USB interfaces on the testing device 2, and at the same time, different computing platforms 3 to be tested are distinguished by the product identifier of the USB interface.
If there is no problem in the wired communication between the testing device 2 and the N computing platforms 3 to be tested, the testing device 2 may obtain the starting results fed back by the N computing platforms 3 to be tested, at this time, the testing device 2 may count how many 1 s appear, and if there are N1 s, it may be determined that the number of normal starting platforms is N.
When the testing device 2 judges that N is equal to N, it can be judged that the N computing platforms 3 to be tested are all started normally.
When the testing device 2 judges that N is not equal to N, for each computing platform 3 in the N computing platforms 3 to be tested, when the testing device 2 judges that the computing platform 3 to be tested and the measuring device can normally communicate based on the IP address of the computing platform 3 to be tested, it indicates that the computing platform 3 to be tested is normally started, otherwise, it indicates that the computing platform 3 to be tested is abnormally started.
After the testing device 2 judges that the computing platform 3 to be tested is started normally, the performance problem result fed back by the computing platform 3 to be tested can be received. Meanwhile, the test device 2 counts the respective repetition times of the results of the different performance problems, and outputs the respective repetition times of the results of the different performance problems to the display 1 for display. Here, the test equipment 2 is used for realizing multiple tests on the plurality of computing platforms 3 to be tested, comprehensively considering the overall performance of the plurality of computing platforms 3 to be tested in the multiple tests, realizing batch tests of the computing platforms 3, improving the test efficiency and ensuring the test accuracy, and when the controller passing the quality test is installed in other products for use, the probability of the controller having problems can be reduced.

and when the number of the normal starting platforms is the same as that of the at least two computing platforms to be tested, the testing equipment judges that each computing platform to be tested is started normally.
