[0039] With the continuous development of wireless communication technology, it has found widespread application in fields such as medical devices, smart homes, and smart cars. The variety and types of wireless communication products are also becoming increasingly diverse. In the smart home sector, wireless communication data acquisition equipment typically receives and outputs signals at different rates, placing high demands on the performance of these devices. The stability and reliability of their transmit power are crucial to system performance. Therefore, performance testing of communication data acquisition equipment is essential before it is released to the market.

[0040] However, the detection of communication acquisition equipment usually adopts the manual testing method, but the manual testing framework is complex and inefficient, resulting in inaccurate test results.

[0041] In order to solve the above technical problems, refer to Figure 1 As shown, an embodiment of the present application proposes a test system for a signal transmission device, wherein the signal transmission device 200 includes a signal input interface, and the test system includes: a signal conversion module 10, a DC power supply module 20, an interference processing module 30, and a switch switching module 40.

[0042] Specifically, the input end of the signal conversion module 10 is used to connect to the host computer 100, and the output end of the signal conversion module 10 is used to connect to the signal input interface of the signal transmission device 200. The signal conversion module 10 is used to convert the first type of signal output by the host computer 100 into a second type of signal and output it to the signal transmission device 200. The DC power supply module 20 includes at least one DC power supply interface, which is used to connect to the signal transmission device 200. The DC power supply module 20 is used to provide power to the signal transmission device 200. The interference processing module 30 is provided on the loop between the signal conversion module 10 and the signal transmission device 200. The interference processing module 30 is used to perform interference processing on the second type of signal. The switch switching module 40 is connected to the interference processing module 30, the signal transmission device 200 and the signal conversion module 10. The switch switching module 40 is used to control the access status of the interference processing module 30.

[0043] In this embodiment, the signal conversion module 10 is used to convert the first type of signal output by the host computer 100 into a second type of signal, and output it to the signal transmission device 200. For example, the host computer 100 can be a computer, and the computer is connected to the signal conversion module 10 via a USB cable. The computer sends a first type of signal (for example, a USB type signal) to the signal conversion module 10 via the USB cable, and the signal conversion module 10 is used to convert the first type of signal output by the host computer 100 into a second type of signal. For example, the signal conversion module 10 can convert a USB type signal into a 485 type signal. The signal conversion module 10 outputs the second type of signal to the signal transmission device 200 through the corresponding communication line for use by the signal transmission device 200. In this embodiment, by setting the signal conversion module 10, the first type of signal sent in the host computer 100 can be converted into a second type of signal for use by the signal transmission device 200, thereby expanding the application scenario of the test system.

[0044] In this embodiment, the DC power supply module 20 is connected to the signal transmission device 200 via a DC power supply interface (when there are multiple device transmission devices 200, multiple DC power supply interfaces are provided accordingly, with each device transmission device 200 corresponding to a DC power supply interface). The DC power supply module 20 is used to provide power to the signal transmission device 200. Specifically, the DC power supply module 20 is used to provide a stable voltage to the signal transmission device 200 when the test system needs to start working, thereby ensuring the stable operation of the signal transmission device 200. In this embodiment, the operating state of the signal transmission device 200 can be controlled by controlling the operating state of the DC power supply.

[0045] In this embodiment, the interference processing module 30 is used to perform interference processing on the second type of signal. Specifically, when the signal conversion module 10 outputs the second type of signal to the signal transmission device 200, there may be signal interference, affecting the stability of the second type of signal. For example, when the second type of signal travels on the transmission line, because its wavelength is shorter than the length of the transmission line, the signal will generate a reflected wave at the end of the transmission line, which may interfere with the original signal (the second type of signal) and affect the stability of the second type of signal. By setting the interference processing module 30, the second type of signal can be interfered with, the stability of the second type of signal can be improved, and the stability of the test system can be further improved.

[0046] In this embodiment, the switch switching module 40 is used to control the access status of the interference processing module 30. Specifically, when some signal transmission devices 200 are being tested, the signal may not be interfered with. At this time, the interference processing module 30 can be disconnected. Then, the working state of the switch switching module 40 can be controlled to control the interference processing module 30 from being connected to the test system, that is, the interference processing module 30 is controlled not to be connected to the signal conversion module 10 and the signal transmission device 200. When some signal transmission devices 200 are being tested, the signal may be interfered with. At this time, the interference processing module 30 can be disconnected. Then, the working state of the switch switching module 40 can be controlled to control the interference processing module 30 from being connected to the test system, that is, the interference processing module 30 is controlled to be connected to the signal conversion module 10 and the signal transmission device 200. In this embodiment, by setting the interference processing module 30, the application scenarios of the test system can be expanded.

[0047] In this embodiment, the test system can test the performance of the signal transmission device 200 by setting up a signal conversion module 10, a DC power supply module 20, an interference processing module 30, and a switch switching module 40. The overall framework is simple, which greatly reduces the complexity of the test. By setting up the interference processing module 30, the test system can further improve the stability of the test system and make the test system more reliable. By setting up the switch switching module 40, the test system can control the state of the interference processing module 30 connected to the test system in different application scenarios, thereby increasing the application scenarios of the test system and improving the flexibility of the test system.

[0048] In some embodiments, reference Figure 3 As shown, the test system of the present application can test multiple signal transmission devices 200 at the same time, has stable performance, can increase the number of one-time tests, and greatly improves the test efficiency.

[0049] In some embodiments, the signal conversion module 10 can be detachably arranged in the test system. When the type of the signal transmission device 200 is different, the signal conversion module 10 can be replaced according to the actual application situation. This application does not limit the type of the signal conversion module 10.

[0050] In some embodiments, the second type of signal may be the same as the first type of signal, that is, the signal conversion module 10 may be just a communication line that merely connects the host computer 100 and the signal transmission device 200 .

[0051] In some embodiments, reference Figure 3 As shown, the signal conversion module 10 is connected to the host computer via a USB cable. The signal conversion module 10 can be a USB to 485 serial port cable, which can be directly purchased and used through an online shopping platform.

[0052] In some embodiments, reference Figure 3 、 Figure 4 As shown, when the signal conversion module 10 is a USB to 485 serial port cable, the output end of the signal conversion module 10 includes 485A and 485B, and when the interference processing module 30 is a first terminal resistor R1, the first terminal resistor R1 is connected in series between 485A and 485B of the signal conversion module 10.

[0053] In some embodiments, the signal transmission device 200 requires a 5V voltage, and the DC power supply module 20 can provide a 5V voltage to provide power to the signal transmission device 200.

[0054] In some embodiments, the DC power supply module 20 may be connected to the host computer 100 , and the operating state of the DC power supply module 20 may be controlled by the host computer 100 .

[0055] In some embodiments, reference Figure 2 、 Figure 4 As shown, the test system further includes: a first switch module 50 .

[0056] Specifically, the first switch module 50 includes at least one first switch unit 51 ; a first end of the first switch unit 51 is connected to the DC power supply interface, and a second end of the first switch unit 51 is connected to the signal transmission device 200 .

[0057] In this embodiment, when there is only one signal transmission device 200 (device under test), there is only one first switch unit 51. When there are multiple signal transmission devices 200, there are multiple first switch units 51, and the number of first switch units 51 is consistent with the number of signal transmission devices 200. Each first switch unit 51 corresponds to one signal transmission device 200. Each first switch unit 51 is used to control the connection between the corresponding signal transmission device 200 and the DC power supply interface. Each first switch unit 51 is used to control whether the DC power supply module 20 supplies power to the corresponding signal transmission device 200. By setting the first switch module 50 to include at least one first switch unit 51, the number of signal transmission devices 200 supplied with power can be controlled, multiple signal transmission devices 200 can be supplied with power at the same time, or only certain signal transmission devices 200 can be supplied with power and tested, thereby improving the flexibility of the test system.

[0058] In some embodiments, reference Figure 4 As shown, the first switch unit 51 includes a first switch K1. A first end of the first switch K1 is connected to the DC power supply interface, and a second end of the first switch K1 is connected to the signal transmission device 200. When there are multiple first switch units 51, each first switch unit 51 has a first switch K1.

[0059] In some embodiments, reference Figure 2 As shown, the test system further includes a shielding module 60 .

[0060] Specifically, the shielding module 60 (for example, it can be a shielding box) includes a cavity and a shell, and the shell surrounds to form a cavity; the signal transmission device 200 is arranged in the cavity of the shielding module 60; the shielding module 60 also includes at least one signal hole, and the output end of the signal conversion module 10 is connected to the signal transmission device 200 through the signal hole.

[0061] In some embodiments, the shielding module 60 further includes at least one power supply hole, and the DC power supply interface is connected to the signal transmission device 200 through the power supply hole.

[0062] In this embodiment, multiple signal transmission devices 200 can be set in the cavity of the shielding module 60. Each signal transmission device 200 is connected to the signal conversion module 10 through a corresponding signal hole, and each signal transmission device 200 is connected to the DC power supply interface of the DC power supply module 20 through a corresponding power supply hole. The shielding module 60 is a sealed cavity. Placing the signal transmission device 200 in the sealed cavity can prevent the signal transmission device 200 from being affected by the external environment, and can make the signal transmission device 200 work more stably.

[0063] Furthermore, by setting up a shielding module 60, the transmission capability of the wireless signal of the signal transmission device 200 can be tested. For example, the input end of the signal transmission device 200 is connected to the signal conversion module 10 through a wired connection, and the output end of the signal transmission device 200 is connected to the data receiving module through a wireless connection. The signal transmission device 200 outputs the second type signal of the signal conversion module 10 to the data receiving module in the form of a wireless signal. By judging the number of messages of the second type signal sent from the upper computer 100 and the number of messages of the wireless signal received by the data receiving module, the data transmission accuracy of the signal transmission device 200 and whether there is packet loss can be judged. The real-time performance of the signal transmission device 200 can be judged by judging the message time sent from the upper computer 100 and the message time received by the data receiving module.

[0064] In some embodiments, the shielding module 60 further includes a knob switch.

[0065] Specifically, the rotary switch is provided on the outer shell of the shielding box and is used to control the shielding coefficient of the shielding box. In this embodiment, by adjusting the shielding coefficient of the shielding box, the penetration capability of the wireless signal of the signal transmission device 200 can be detected. For example, the wireless signal can be a Bluetooth signal.

[0066] In some embodiments, reference Figure 3As shown, the switch module 40 includes a first switch unit 41 and a second switch unit 42 .

[0068] In this embodiment, the first switching unit 41 and the second switching unit 42 are used to control the access status of the interference processing module 30. For example, when some signal transmission devices 200 are being tested, the signal may not be interfered with. In this case, the interference processing module 30 can be disconnected. In this case, the first switching unit 41 can be controlled to be turned on and the second switching unit 42 can be controlled to be turned off. In this case, the interference processing module 30 is not connected to the test system. When some signal transmission devices 200 are being tested, the signal may be interfered with. In this case, the interference processing module 30 can be connected. In this case, the second switching unit 42 can be controlled to be turned on and the first switching unit 41 can be controlled to be turned off. In this case, the interference processing module 30 is connected to the test system. By setting the first switching unit 41 and the second switching unit 42, the state of the interference processing module 30 connecting to the test system can be controlled, and the application scenarios of the test system can be expanded.

[0070] In some embodiments, reference Figure 2 、 Figure 4 As shown, the test system further includes: a second switch module 70 .

[0071] Specifically, the second switch module 70 includes at least one second switch unit 71 ; a first end of the second switch unit 71 is connected to the output end of the signal conversion module 10 , and a second end of the second switch unit 71 is connected to the signal transmission device 200 .

[0072] In this embodiment, when multiple signal transmission devices 200 are included, the second switch module 70 includes multiple second switch units 71, one second switch unit 71 corresponding to each signal transmission device 200, and each second switch unit 71 is used to control the connection between the corresponding signal transmission device 200 and the output end of the signal conversion module 10. By configuring the second switch module 70 to include at least one second switch unit 71, the number of second-type signals output to the signal transmission devices 200 can be controlled, and the second-type signals can be provided to multiple signal transmission devices 200 simultaneously, allowing for simultaneous testing of the multiple signal transmission devices 200. Alternatively, the second-type signals can be provided to only certain signal transmission devices 200, allowing for testing of only certain signal transmission devices 200, thereby enhancing the flexibility of the test system.

[0073] In some embodiments, reference Figure 4 As shown, the second switch unit 71 includes a fourth switch K4 , a first end of the fourth switch K4 is connected to the output end of the signal conversion module 10 , and a second end of the fourth switch K4 is connected to the signal transmission device 200 .

[0074] In some embodiments, the test system further includes: a data receiving module.

[0075] Specifically, the data receiving module is disposed outside the shielding box, and the data receiving module is used to establish a wireless connection with the signal transmission device 200 .

[0076] In this embodiment, the data receiving module is used to receive the wireless signal output by the signal transmission device 200, wherein the data receiving module can be a mobile phone, a tablet, a comprehensive tester, a spectrum analyzer, etc., and the wireless signal can be a Bluetooth signal, etc. By setting the data receiving module, the wireless transmission capability of the signal transmission device 200 can be tested. For example, by judging the number of messages of the second type of signal sent by the host computer 100 and the number of messages of the wireless signal received by the data receiving module, the data transmission accuracy and whether there is packet loss of the signal transmission device 200 can be judged. By judging the time of the message sent by the host computer 100 and the time of the message received by the data receiving module, the real-time performance of the signal transmission device 200 can be judged, thereby expanding the application scenarios of the test system.

[0077] In some embodiments, the interference processing module 30 includes: a first stabilization unit.

[0078] Specifically, refer to Figure 4 As shown, the first stabilizing unit includes a first terminal resistor R1 , a first end of the first terminal resistor R1 is connected to the signal conversion module 10 , and a second end of the first terminal resistor R1 is connected to the signal transmission device 200 .

[0079] In this embodiment, more specifically, the first end of the first terminal resistor R1 is connected in series with the second switching unit 42 and then connected to the signal conversion module 10. When the second switching unit 42 is disconnected (cutoff), the first terminal resistor R1 is not connected to the test system. At this time, the first terminal resistor R1 is in an open circuit state. When the second switching unit 42 is closed and turned on, the first terminal resistor R1 is in a conductive state. At this time, the first terminal resistor R1 is connected to the test system. The first terminal resistor R1 can interfere with the second type of signal. For example, when the second type of signal travels on the transmission line, due to its wavelength being shorter than the length of the transmission line, the signal will generate a reflected wave at the end of the transmission line, which may interfere with the original signal. By setting the first terminal resistor R1, the signal energy can be absorbed and prevented from being reflected, thereby improving the accuracy and stability of the test system.
