Meanwhile, the reset module is also connected with the intelligent voice board, so that the state of each hardware device in the intelligent voice board can be set, and a technical guarantee is provided for production and test of the intelligent voice board. The reset module is mainly used for restoring each hardware in the intelligent voice board to an initial default state by running a program of the reset module, so that early-stage preparation is made for detection of each hardware.
In an embodiment of the invention, the test module is connected with and runs on the operating system and the platform module, and the test module is also connected with each hardware device of the smart voice board and the prompt module in the smart voice board production test system respectively. The testing module mainly adopts an internally set program to detect the hardware to be detected in an initial default state so as to judge whether each hardware to be detected is normal, and then the testing module records the detection result of each hardware and transmits the detection result to the prompting module. The testing module mainly comprises a loudspeaker testing module, a microphone testing module, a universal asynchronous receiving and transmitting transmitter testing module, a WIFI testing module, a Bluetooth testing module, a GPIO testing module and other sub-modules. In the testing process of the intelligent voice board, the testing module sequentially tests the loudspeaker, the microphone, the universal asynchronous receiving and transmitting transmitter, the WIFI and the GPIO according to the sequence.

The prompt module in the invention is connected with and runs on the operating system and the platform module. Meanwhile, the prompt module is also connected with the test module. The intelligent voice board detection device receives detection results of each hardware in the intelligent voice board transmitted by the test module, and then the prompt module processes each detection result and generates a corresponding detection report. Preferably, the main content of the detection report is whether the working state of each hardware device in the smart voice board is normal. The detection report is transmitted to the operating system and the platform by the prompt module, and is printed out in a text mode or is broadcasted in a voice mode, so that a tester can master the state of each hardware in the intelligent voice board and control the quality of the intelligent voice board.
Fig. 2 shows a specific implementation of the process of the smart voice board production testing method according to the present invention. The intelligent voice board production and test process in the specific implementation mode mainly comprises the following steps:
s201 is a step of connecting the voice board with the operating system and the platform. In this step, the production testing technician connects the operating system and the platform (upper computer) to the intelligent voice board to be produced and tested via the serial port.
S202 is a production environment forming step. In this step, the production and test personnel start and operate the operating system and the platform, thereby forming a production and test environment of the intelligent voice board. After the operating system and the platform normally run, the CPU, the WIFI loading and the Bluetooth loading are reset, so that the working state of the detection mode of the intelligent voice board production test is started, and at the moment, the operating system and the platform can print out log information of 'starting test' through a serial port.
S203 is a reset step. In the detection mode working state, the self program of the reset module in the intelligent voice board production and test system starts to run, so that each hardware device in the intelligent voice board is restored to the initial default state.
S204 is a testing step. In this step, the test module in the intelligent voice board production test system runs an internal program, and detects each hardware device of the intelligent voice board in an initial default state one by one according to a sequence, preferably, the sequence of each hardware device test is a speaker test, a microphone test, a universal asynchronous transceiver transmitter test, a WIFI test, a bluetooth test and a GPIO test. Then, the detection module judges whether each hardware device is normal according to the detection process, and simultaneously the test module records the detection and judgment results of each hardware module. The test module also transmits the recorded detection and judgment results to the prompt module. In the testing step, the detailed description of each sub-module in the testing module may be referred to for the specific testing process of each hardware device of the smart voice board. And immediately testing the next hardware equipment after the testing of each hardware equipment is finished until all the hardware equipment is tested and the whole testing process is finished. The detection of each hardware device is not affected by the detection result of the previous hardware device, that is, the detection process of the next hardware device is started no matter whether the detection result of one hardware device is normal or not.
In an embodiment of the present invention, before each hardware device is tested, the operating system and the platform print out a log of "certain hardware test" through the serial port. When the hardware equipment test succeeds, the operating system and the platform can print and output a log of 'certain hardware test succeeds' through the serial port, and if the hardware equipment test fails, the operating system and the platform can print and output a log of 'certain hardware test fails' through the serial port. For example: in the UART test process, a serial port prints a UART test log before entering the UART test, and then the RX and the TX of the UART are short-circuited to carry out self-sending and self-receiving tests. If the test is successful, the serial port prints a log of 'UART test success'. If the test fails, a log of "UART test failure" is printed out. Similarly, in the WIFI test process, the log of the WIFI test can be printed out by the serial port before entering the WIFI test, then the WIFI networking test is carried out, the voice board can ping the external network at the moment, if the voice board can ping the external network, the WIFI test is successful, and the log of the WIFI test is printed out by the serial port. And if the test fails, a log of 'WIFI test failure' is printed out.
S205 is a detection report generation step. In this step, a prompt module in the smart voice board production test system receives the test result of each hardware device transmitted by the test module, and generates a test report according to the test result. And then, the prompt module transmits the generated detection report to an operating system and a platform through a serial port. The operating system and the platform transmit the detection report to a tester in a text form and/or a voice broadcasting form, so that the tester can master the state of each hardware in the intelligent voice board and control the quality of the intelligent voice board.
The invention adopts a black box test mode to test the intelligent voice board, and combines an operating system, a platform (upper computer) and the intelligent voice board. After the test is finished, the detection result is transmitted to a tester in a text report form or a voice broadcast mode through an operating system and a platform (upper computer). Therefore, the intelligent voice board testing method has the characteristics of simple and continuous testing process operation, accurate testing result and concise and prominent result display.
When the method is applied, the efficiency of production and test of the intelligent voice board can be improved, the production process and the production period of the intelligent voice board are shortened, and the operation cost of enterprises is reduced.
