在实际应用中，可以采用音频采集电路对音频模块发出的音频信号进行采集。具体的，在对待测主板上的音频模块进行测试时，控制终端输出控制指令至音频模块，以使音频模块发出音频信号。采集音频模块发出的音频信号，并将采集到的音频信号输出至控制终端，以使控制终端对音频模块进行测试。具体的，控制终端可以通过分析音频信号的幅值、频率或者失真度等参数来判断音频模块是否合格，若音频信号的幅值、频率及失真度等均在预设范围内，则判断音频模块合格。In practical application, the audio signal sent by the audio module can be collected by using the audio collection circuit. Specifically, when testing the audio module on the mainboard to be tested, the control terminal outputs a control command to the audio module, so that the audio module sends out an audio signal. The audio signal sent by the audio module is collected, and the collected audio signal is output to the control terminal, so that the control terminal can test the audio module. Specifically, the control terminal can judge whether the audio module is qualified by analyzing parameters such as the amplitude, frequency, or distortion of the audio signal. If the amplitude, frequency, and distortion of the audio signal are all within the preset range, the audio module can be judged qualified.
在本发明实施例中，电平信号测试单元根据预设测试程序对待测主板上的预设功能模块的电平信号进行测试。In the embodiment of the present invention, the level signal testing unit tests the level signals of the preset functional modules on the mainboard to be tested according to a preset test program.
在实际应用中，预设功能模块可以根据订单信息中的POS配置信息进行确定，此处不做限制。例如，预设功能模块可以包括打印模块、电源模块等。In practical applications, the preset function module may be determined according to the POS configuration information in the order information, which is not limited here. For example, the preset function modules may include a printing module, a power supply module, and the like.
在本发明实施例中，可以采用由电压检测单元和模数转换器构成的采集电路对预设模块的电平信号进行采集。具体的，通过电压检测单元采集预设功能模块的预设信号的电压值，通过模数转换器将电压值转换为数字值后输出至控制终端，以使控制终端对预设功能模块的预设信号的电平进行判断。In the embodiment of the present invention, a collection circuit composed of a voltage detection unit and an analog-to-digital converter may be used to collect the level signal of the preset module. Specifically, the voltage value of the preset signal of the preset function module is collected by the voltage detection unit, and the voltage value is converted into a digital value by an analog-to-digital converter and then output to the control terminal, so that the control terminal can preset the preset function module The level of the signal is judged.
例如，采集待测主板上的电源模块的输出信号的电压值，并将点电压值转换为数字信号输出至控制终端，控制终端判断该数字信号是否为高电平信号，若为高电平信号，则说明电源模块合格。For example, collect the voltage value of the output signal of the power module on the motherboard to be tested, and convert the point voltage value into a digital signal and output it to the control terminal. The control terminal judges whether the digital signal is a high-level signal, and if it is a high-level signal , it means that the power module is qualified.
在所有预设功能模块均测试完成后，自动控制装置对待测主板进行断电。此时，控制终端显示测试结果，并待测主板上的各个功能模块均合格，则控制终端将根据订单信息生成的扩展序列号发送至生产管理系统，以使生产管理系统对该扩展序列号进行存储和备案。After all the preset function modules are tested, the automatic control device powers off the main board to be tested. At this time, the control terminal displays the test results, and all functional modules on the main board to be tested are qualified, then the control terminal sends the extended serial number generated according to the order information to the production management system, so that the production management system can check the extended serial number. storage and filing.
由此可以看出，本发明实施例提供的一种POS机主板的自动测试装置的自动测试方法，若检测到待测主板被正确装载至所述自动测试装置的至少一个测试夹具中，则对所述待测主板上的备用电源进行测试；若检测到所述备用电源测试完成，则获取所述控制终端根据所述待测主板对应的订单信息输出的扩展序列号和预设测试程序，并将所述扩展序列号和所述预设测试程序输出至所述待测主板上相应的功能模块；获取所述控制终端通过预设下载工具下载的预设应用程序，并将所述预设应用程序下载至所述待测主板上的主控模块；在所述待测主板上电后，根据所述预设测试程序，对所述待测主板上相应的功能模块进行功能测试。从而使得测试人员只需将待测电路板放置在自动测试装置的测试夹具中，便可自动完成对待测电路板的程序配置及功能测试，简化了人工操作步骤，且测试人员可同时操作多个自动测试装置以同时对多个待测电路板进行测试，极大地提高了测试效率以及测试的稳定性和准确性。It can be seen that, in the automatic testing method of the automatic testing device of a kind of POS machine main board provided by the embodiment of the present invention, if it is detected that the main board to be tested is correctly loaded in at least one test fixture of the automatic testing device, then the The backup power supply on the mainboard to be tested is tested; if it is detected that the backup power supply test is completed, the extended serial number and the preset test program output by the control terminal according to the order information corresponding to the mainboard to be tested are obtained, and Output the extended serial number and the preset test program to the corresponding functional modules on the mainboard to be tested; obtain the preset application program downloaded by the control terminal through the preset download tool, and apply the preset The program is downloaded to the main control module on the main board to be tested; after the main board to be tested is powered on, a functional test is performed on the corresponding functional modules on the main board to be tested according to the preset test program.
