[0025] The utility model proposes an optical modem motherboard testing device, referring to Figure 1 , the optical modem motherboard testing device includes:

[0026] The single-chip microcomputer 100 is provided with a communication serial port, and the communication serial port is used to communicate with the optical modem mainboard 200, so as to at least receive the serial port printing information and test results of the optical modem mainboard 200;

[0027] The first wireless communication module 300 is used to receive test instructions and feed back to the single-chip microcomputer so that the single-chip microcomputer executes the test program of the optical modem motherboard.

[0028] The utility model is aimed at the stability and reliability test (aging test) of the optical modem motherboard, and the test generally needs to be carried out in a high and low temperature environment. The conventional method is to implement the test through a USB data cable and a control computer communication control. However, the USB data cable is easily disturbed by the high and low temperature environment, thereby affecting the test accuracy and test results. Therefore, a complete set of solutions is needed for test verification to ensure that the stability and reliability of the solution design meet expectations.

[0029] The optical modem motherboard test device involved in the present embodiment mainly includes a single-chip computer 100 and a first wireless communication module 300. By adopting wireless communication instead of the existing communication control with a control computer using a data line, the influence of environmental changes on the test accuracy and test results during the test of the optical modem motherboard 200 can be reduced, thereby ensuring the stability of the transmission of test instructions. In addition, the single-chip computer 100 and the optical modem motherboard 200 are connected for communication via a serial port, and the serial port print information of the optical modem motherboard 200 can be collected, so as to accurately judge the test results of each power on and off test, and avoid the optical modem motherboard 200 not starting normally during the test and being unable to obtain the results, thereby ensuring the accuracy of the test results.

[0030] Serial port printing information is usually used to record the running status and debugging information of the program during the development process. In this embodiment, the serial port printing information is mainly used to determine whether the optical modem motherboard 200 is normally powered on each time the power is turned on. The power on and off test results of the optical modem motherboard can be obtained efficiently and accurately through serial port transmission, avoiding the situation where the results cannot be obtained because the optical modem motherboard 200 is not normally started during the test, and can further ensure the accuracy of the test results. Serial port printing information usually uses the printf function to print information, and different log levels can be used to distinguish the type of information, such as info (initialization), debug (running process) and error (error). For example, use "[info]" to mark info-level information, use "[debug]" to mark debug-level information, and use "[error]" to mark error-level information.

[0031] In some embodiments, the first wireless communication module 300 is a Bluetooth module, and the Bluetooth module is used to receive a test instruction sent by the terminal device 400 and feed it back to the single chip microcomputer 100 .

[0032] In this embodiment, since the test is more susceptible to interference in high and low temperature environments, the strong anti-interference ability of Bluetooth wireless transmission is utilized, and the test instructions issued by the Bluetooth receiving terminal device are fed back to the microcontroller 100 to execute the test program of the optical modem motherboard 200. This can ensure the stability of the transmission of test instructions and reduce interference caused by other factors such as environmental factors (high and low temperature environment during the aging test process).

[0033] In some embodiments, reference Figure 2 The optical modem mainboard testing device also includes a second wireless communication module 500, which is used to transmit the test data and test results of the optical modem mainboard 200 to the terminal device 400.

[0034] In this embodiment, the transmission of test data and test results is also performed by wireless transmission, which can facilitate test personnel to obtain test data and test result information in real time even if they are not on site, thereby further saving manpower and time costs.

[0035] In some embodiments, the second wireless communication module 500 is a WiFi module.

[0036] Compared with Bluetooth wireless transmission, WiFi wireless transmission can provide higher transmission speed and can download and upload large amounts of data faster. Since this embodiment will generate a large amount of test data during the test process, the WiFi module is selected to transmit the test data and test results to the terminal device 400 via wireless transmission for user query.

[0037] In some embodiments, the optical modem motherboard testing device also includes a relay module 600 , which is electrically connected to the single-chip computer 100 and the optical modem motherboard 200 and is used to control the on and off of the power supply of the optical modem motherboard 200 .

[0038] A relay is an electrical control device. When the change of the input quantity (excitation quantity) reaches the specified requirements, a predetermined step change occurs in the controlled quantity in the electrical output circuit. It can transfer current, signal or control from one circuit to another circuit to achieve the "inheritance" or "transfer" of electrical signals. In this embodiment, by setting a relay module 600 between the single-chip microcomputer 100 and the optical modem mainboard 200, the single-chip microcomputer 100 can send instructions to the relay module 600 at any time after receiving the test instruction, thereby controlling the on and off of the power supply of the optical modem mainboard 200, so as to monitor whether the optical modem mainboard 200 can start normally, and then achieve accurate control of the test results (aging of the optical modem mainboard 200).

[0039] In some embodiments, the relay module 600 is provided with at least two electrical connection ports, and the at least two electrical connection ports are electrically connected to the single-chip computer 100 and at least two optical modem mainboards 200, respectively, so as to control the on and off of the power supply of at least two optical modem mainboards 200;

[0040] The single chip microcomputer 100 is provided with at least two communication serial ports, and the at least two communication serial ports are respectively used for communication connection with the at least two optical modem mainboards 200 one by one, so as to respectively receive serial port printing information and test results of each of the optical modem mainboards 200.

[0041] By setting multiple connection ports and multiple communication serial ports, it is possible to simultaneously test multiple optical modem mainboards 200. In this embodiment, the relay module 600 is preferably provided with 7 electrical connection ports, and the single-chip microcomputer 100 also has 7 communication serial ports for serial port transmission with the optical modem mainboard 200, that is, aging tests can be performed on 7 optical modem mainboards 200 in high and low temperature environments at the same time, thereby greatly improving the test efficiency and reducing the product development cycle.

[0042] In some embodiments, the optical modem motherboard testing device further includes a temperature detection module 700 , and the temperature detection module 700 is used to collect the temperature of the test environment when testing the optical modem motherboard 200 and feed it back to the single-chip computer 100 .

[0043] In this embodiment, by setting up a temperature detection module 700, temperature data in the test environment can be collected and fed back to the single-chip microcomputer 100 when the optical modem mainboard is subjected to stability and reliability testing. After receiving the temperature data, the single-chip microcomputer 100 performs ADC conversion (analog-to-digital conversion) on it and then transmits the temperature data back to the terminal device 400 through the second wireless communication module 500, thereby facilitating accurate judgment of the environmental conditions during the test process, thereby improving the accuracy of the test data and test results.

[0044] In order to further improve the accuracy of test data and test results, in some embodiments, a temperature adjustment module may be provided, which is connected to the single-chip microcomputer 100 for communication. When the temperature detection module 700 detects that a large change has occurred in the temperature of the test environment, a temperature abnormality warning is sent to the single-chip microcomputer 100. After receiving the temperature abnormality warning, the single-chip microcomputer 100 sends a temperature adjustment instruction to the temperature adjustment module, thereby adjusting the temperature of the test environment to a reasonable range.

[0045] In some embodiments, the optical modem motherboard testing device further includes a humidity detection module 800 , and the humidity detection module 800 is used to collect the humidity of the test environment when testing the optical modem motherboard 200 and feed it back to the single-chip computer 100 .

[0046] In this embodiment, by setting up a humidity detection module 800, the humidity data in the test environment can be collected and fed back to the single-chip microcomputer 100 when the optical modem mainboard is subjected to stability and reliability testing. After receiving the humidity data, the single-chip microcomputer 100 performs ADC conversion (analog-to-digital conversion) on it and then transmits the humidity data back to the terminal device 400 through the second wireless communication module 500, thereby facilitating accurate judgment of the environmental conditions during the test process, thereby improving the accuracy of the test data and test results.

[0047] In order to further improve the accuracy of test data and test results, in some embodiments, a humidity adjustment module may be provided, which is connected to the single-chip microcomputer 100 for communication. When the humidity detection module 800 detects that a significant change has occurred in the humidity in the test environment, a humidity abnormality warning is sent to the single-chip microcomputer 100. After receiving the humidity abnormality warning, the single-chip microcomputer 100 sends a humidity adjustment instruction to the humidity adjustment module, thereby adjusting the humidity of the test environment to a reasonable range.

[0048] In some embodiments, the optical modem motherboard testing device further includes a power module 900 , and the power module 900 is electrically connected to the single-chip computer 100 for supplying power to the single-chip computer 100 .

[0049] In this embodiment, the power module 900 can be a single one, which is responsible for the power supply of the single-chip microcomputer 100 and multiple optical modems at the same time, that is, the single-chip microcomputer 100 and the optical modem are uniformly powered by the same power supply; or, the power module 900 can also be multiple, and some of the multiple power modules 900 are responsible for the power supply of the single-chip microcomputer 100, and the other part of the power modules 900 are responsible for the power supply of multiple optical modems, that is, the single-chip microcomputer 100 and the optical modem are separately powered by different power supplies. Regardless of whether the optical modem and the single-chip microcomputer 100 are powered by the same power supply or different power supplies, they are connected to the power module through the relay module 600, so as to facilitate the relay module 600 to control the power on and off of the optical modem.

[0050] Furthermore, since the operating voltages of the single-chip microcomputer 100 and the optical modem are different, it is necessary to convert the voltage output by the power module 900, and therefore, the power module 900 further includes: a first voltage conversion module 910 and a second voltage conversion module 920. The first voltage conversion module 910 is electrically connected to the power module 900 and the single-chip microcomputer 100, respectively, and the first voltage conversion module 910 converts the operating voltage output by the power module 900 to the single-chip microcomputer 100; the second voltage conversion module 920 is electrically connected to the power module 900 and multiple optical modem motherboards 200, respectively, and the second voltage conversion module 920 converts the operating voltage output by the power module 900 to multiple optical modem motherboards 200.

[0051] In this embodiment, the terminal device 400 is selected from a mobile phone, a tablet computer, a handheld computer, a PDA, and a server.
