Alternatively, the CAN bus may be a multi-master bus, and the communication medium may be twisted pair, coaxial cable, or optical fiber, which is not limited in this embodiment.
And the industrial personal computer 1 is used for sending a test task to the vehicle-mounted Bluetooth module 31 through Bluetooth by the control terminal 2. The industrial personal computer 1 may be an intelligent device that directly sends and receives instruction information, and is used to manage various tests in the development process of the entire vehicle platform, and may be a computer, for example. Alternatively, the terminal 2 may be a remote control terminal such as a mobile terminal, for example, a smart phone, a tablet computer, or a fixed terminal such as a computer. For example, the terminal 2 may be a mobile phone and is installed with an application program for transmitting instruction information through bluetooth. The test tasks may include, but are not limited to, opening windows, closing a sunroof, adjusting air conditioner temperature, opening music, etc., and may be determined according to the control function of the terminal 2 for the vehicle. It should be noted that the terminal 2 and the vehicle-mounted bluetooth module 31 establish a bluetooth connection in advance to simulate the bluetooth connection between the terminal and the vehicle, and the test task is sent from the terminal 2 to the vehicle-mounted bluetooth module 31 in the form of a radio frequency signal.
In this embodiment, the industrial personal computer 1 optionally comprises a control module 11 and a test bridge tool 12. The control module 11 calls the test bridge tool 12 to send a trigger instruction of the test task to the terminal 2. The test bridge tool 12 may be understood as a call interface, and is configured to call instruction information in the control module 11 and send the instruction information to the terminal 2, so as to implement automatic operation on the terminal 2. In some embodiments, the test bridge tool 12 may be an adb (android Debug bridge) module. The triggering instructions of the test task may be pre-written program code that may execute the instructions that trigger the test task.
After receiving the test task sent by the terminal 2, the vehicle-mounted bluetooth module 31 converts the test task from a radio frequency signal to a CAN test signal, and sends the CAN test signal to the gateway 32. The gateway 32 may be a computer system or device that provides data conversion services among multiple networks, and may be configured to repackage the received data information to meet the needs of the destination system, and to perform filtering and security functions.
The gateway 32 sends the CAN test signal to the industrial personal computer 1, receives a reply signal of the industrial personal computer 1, and sends the reply signal to the vehicle-mounted Bluetooth module 31; the vehicle-mounted bluetooth module 31 converts the reply signal into a radio frequency signal, and transmits the radio frequency signal to the terminal 2. The reply signal may be a feedback signal of the industrial personal computer 1 after executing a related task, and optionally, the industrial personal computer 1 may be a reply signal simulating a CAN test signal to simulate a process of a vehicle actuator responding to the CAN test signal, wherein each CAN test signal may be preset with at least one reply signal, and the industrial personal computer 1 calls the reply signal corresponding to the CAN test signal after receiving the CAN test signal; optionally, the industrial personal computer 1 may also be connected to a plurality of controllers of the vehicle, and after receiving the CAN test signal, sends the CAN test signal to the corresponding actuator, and receives a reply signal corresponding to the actuator. The actuator CAN include but is not limited to a window controller, an air conditioner controller, a skylight controller and the like, and the industrial personal computer 1 sends the CAN test signal to the window controller under the condition that the CAN test signal is a window control signal.
Optionally, the reply signal includes a normal reply signal and an abnormal reply signal. Specifically, when the industrial personal computer 1 can simulate the normal execution process of the test task, a normal reply signal is fed back; when the simulation test task of the industrial personal computer 1 encounters a problem and the situation that the execution cannot be performed or the execution is wrong occurs, an abnormal reply signal is fed back, and optionally, a signal value in the abnormal reply signal can be an invalid value, a super-boundary value or an execution failure identifier and the like. It should be noted that, the terminal 2 may display the received radio frequency signal to the tester through the display interface of the test management software, or may generate and store a test report, and the like.
In the specific implementation, after the industrial personal computer 1 obtains the test request, the control module 11 generates a trigger instruction of the test task according to the test request, and sends the trigger instruction to the terminal 2 through the test bridge tool 12, so that the terminal 2 sends the test task corresponding to the test request to the vehicle-mounted bluetooth module 31 located on the test bench 3 through bluetooth, because the vehicle-mounted bluetooth module 31 is connected with the gateway 32 through the CAN bus, after receiving the test task sent by the terminal 2, the vehicle-mounted bluetooth module 31 converts the test task from a radio frequency signal into a CAN test signal, and sends the CAN test signal to the gateway 32, after receiving the CAN test signal, the gateway 32 sends the CAN test signal to the industrial personal computer 1, after receiving the CAN test signal, the industrial personal computer 1 executes the test task corresponding to the CAN test signal, generates a reply signal, and feeds the reply signal back to the gateway 32, and after receiving the reply signal by the gateway 32, will send it to on-vehicle bluetooth module 31, in order to return to terminal 2 again, on-vehicle bluetooth module 31 needs convert the reply signal into radio frequency signal to send radio frequency signal to terminal 2, so that can carry out validity judgement with the test task feedback result that receives according to terminal 2 to whole test flow.
On the basis of the above embodiment, optionally, the industrial personal computer 1 is further configured to monitor transmission signals in a transmission path of the test task and a reply path of the test task, and determine a test result based on the monitored transmission signals. The signals that industrial personal computer 1 CAN monitor include the CAN test signal and the reply signal transmitted between vehicle-mounted Bluetooth module 31 and gateway 32, and the CAN test signal and the reply signal transmitted between gateway 32 and industrial personal computer 1.
The transmission path can be any path in the process of sending the test task from the terminal 2 to the industrial personal computer 1. Similarly, the reply path may refer to any path in the process of sending the reply signal to the terminal 2 after the industrial personal computer 2 executes the test task. In the present embodiment, the transmission signal may include, but is not limited to, a radio frequency signal, a CAN test signal, a reply signal, and the like.

Optionally, the determining, by the industrial personal computer 1, the test failure based on the monitored transmission signal may include: the industrial personal computer 1 determines that the test fails under the condition that at least one transmission signal is not monitored, and determines an abnormal component based on the transmission signal which is not monitored, or the industrial personal computer 1 compares the signal content of each transmission signal with the standard signal content under the condition that each transmission signal is monitored, if any signal content fails to be compared, the test fails, and determines the abnormal component based on the signal content which fails to be compared. For example, in the process of transmitting the test task from the terminal 2 to the industrial personal computer 1, the industrial personal computer 1 does not monitor the transmission signal between the vehicle-mounted bluetooth module 31 and the gateway 32, but monitors the transmission signal between the gateway 32 and the industrial personal computer 1, and thus it may be determined that the test has failed, and it may be further determined that the abnormal component is the vehicle-mounted bluetooth module 31.
Correspondingly, the industrial personal computer 1 determines that the test is successful based on the monitored transmission signals, and the industrial personal computer 1 compares the signal content of each transmission signal with the standard signal content under the condition that each transmission signal is monitored, and determines that the test is successful if any signal content is successfully compared.
The standard signal content may be understood as signal information that is preset and used for determining whether the test is successful.
In specific implementation, in the testing process, the industrial personal computer 1 can also determine whether the testing task is successfully sent to the industrial personal computer 1 from the terminal 2 by monitoring a transmission signal on a transmission path of the testing task, and determine whether a reply signal is successfully fed back to the terminal 2 from the industrial personal computer 1 after the testing task is executed by monitoring a transmission signal on a reply path of the testing task. Further, if the industrial personal computer 1 does not monitor any one of the transmission signals or the condition that the signal content of the transmission signal is not matched with the preset standard signal content, it may be determined that the current test process fails, and an abnormal component causing the test failure may be determined according to the transmission signal whose transmission signal content is not matched, so that the tester may process the abnormal component in time and restart a new round of test process.
On the basis of the above embodiments, the test system further comprises a data transceiver. Wherein, data transceiver CAN include a plurality of ports, respectively with the CAN bus between on-vehicle bluetooth module 31 and the gateway 32, the CAN bus between gateway 32 and the industrial computer 1 to and industrial computer 1 is connected. The data transceiver CAN be located between industrial personal computer 1 and test bench 3 for transmit signal on the CAN bus between monitoring vehicle-mounted Bluetooth module 31 and gateway 32, and transmit signal on the CAN bus between gateway 32 and industrial personal computer 1, and send to industrial personal computer 1. The transmission signals on the CAN bus monitored by the data transceiver comprise CAN test signals on a transmission path of a test task and reply signals on a reply path of the test task. Specifically, the transmission signal includes a CAN test signal of a CAN bus between the vehicle-mounted bluetooth module 31 and the gateway 32, a CAN test signal on the CAN bus between the gateway 32 and the industrial personal computer 1, a reply signal of the CAN bus between the vehicle-mounted bluetooth module 31 and the gateway 32, and a reply signal on the CAN bus between the gateway 32 and the industrial personal computer 1. And if any transmission signal is not monitored and/or the signal value of any monitored transmission signal is incorrect, determining that the test bench fails to test.
On the basis of the above embodiments, the control module 11 in the industrial personal computer 1 is further configured to obtain a reply interface image displayed on the terminal 2 through the test bridge tool 12, and determine whether the reply interface image matches with a reply signal of the control module 11.
In specific implementation, the industrial personal computer 1 generates a reply signal to be fed back to the terminal 2 after executing a test task, in order to determine whether the reply signal received by the terminal 2 is consistent with the reply signal sent by the industrial personal computer 1, the control module 11 in the industrial personal computer 1 can obtain a reply interface image displayed after the terminal 2 receives the reply signal by calling the test bridge tool 12, and compare the obtained reply interface image with the reply signal generated by the control module 11 to determine whether the reply interface image is matched with the reply signal so as to determine whether the test is successful or failed again according to a comparison result.
It should be noted that the test task may be a test task of at least one bluetooth key. The industrial personal computer 1 can sequentially send a trigger instruction of a test task to the terminal based on a preset test sequence of a plurality of test tasks; accordingly, the test result is determined based on the transmission information detected during the test for each test task.
