[0002] In special vehicle systems, the tested equipment, such as computers, is used for data processing and issuing commands. Its main function is to calculate firing parameters according to a set trajectory based on target data and meteorological parameters provided by the detector, and transmit these parameters to the weapon launching device in real time, thereby controlling the weapon to automatically track and attack the target. As the core equipment of the system, the quality of the output signal of the tested equipment is crucial.

[0003] Since the equipment under test will be deployed with the vehicle to operate in extreme environments such as hot and cold regions, it is necessary to conduct separate tests on the equipment under test, such as high and low temperature tests and shock and vibration tests, before installation on the vehicle. In order to facilitate the detection of the signal quality of the equipment under test, a simple, intuitive and clear detection method and device need to be designed. Summary of the Invention

[0004] In view of this, the present invention provides a high-speed signal quality detection method and apparatus, which can independently detect the signal quality of the output signal of the device under test.

[0005] The present invention adopts the following specific technical solution:

[0006] This invention provides a high-speed signal quality detection method. The method employs a signal detection device, which includes a high-speed signal frequency division and reduction processing unit, an I / O signal generation unit, an industrial control computer, and a display screen. The detection method includes the following steps:

[0007] Step 1: Use the high-speed signal spread spectrum reduction processing unit of the signal detection device to acquire the high-speed signal of the device under test, and then perform frequency division and reduction processing on the acquired high-speed signal in sequence.

[0008] Step 2: Use the I / O signal generation unit to collect data from the signal after speed reduction processing, and send the collected data to the industrial control computer;

[0009] Step 3: The industrial control computer compares the collected data with the pre-stored data and displays the comparison results on the screen.

[0010] Furthermore, in step three, the industrial control computer collects data in real time through threads and develops a detection interface design unit through virtual instrument development software. The detection interface design unit then displays the detection results on the display screen.

[0011] Furthermore, in step three, the detection interface design unit displays the comparison results via indicator lights on the display screen.

[0012] Furthermore, in step one, the high-speed signal spread spectrum reduction processing unit acquires the high-speed signal of the device under test through the chip. The high-speed signal is a microsecond-level narrow pulse signal.

[0013] In step two, the I / O signal generation unit is the I / O interface in the board.

[0014] In addition, the present invention also provides a high-speed signal quality detection device, which includes a high-speed signal frequency division and speed reduction processing unit, an I / O signal generation unit, an industrial control computer, and a display screen;

[0015] The high-speed signal frequency division and speed reduction processing unit is used to connect to the device under test, collect high-speed signals from the device under test, and perform frequency division and speed reduction processing on the collected high-speed signals in sequence.

[0025] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] This invention provides a high-speed signal quality detection method, such as... Figure 1 and Figure 2 As shown, this detection method uses a high-speed signal quality detection device for detection, wherein:

[0027] like Figure 2 As shown, the high-speed signal quality detection includes a high-speed signal frequency division and speed reduction processing unit 1, an I / O signal generation unit 2, an industrial control computer 3, and a display screen 4;

[0028] The high-speed signal frequency division and speed reduction processing unit 1 is used to connect to the device under test 5, acquire high-speed signals from the device under test 5, and perform frequency division and speed reduction processing on the acquired high-speed signals in sequence; the high-speed signal spread spectrum speed reduction processing unit acquires the high-speed signals of the device under test 5 through the 161 chip, and the high-speed signals are microsecond-level narrow pulse signals; in this embodiment, the device under test 5 is described as a computer in a military vehicle with a weapon launching device, and the military vehicle has gunner's working mode and vehicle commander's working mode;

[0029] I / O signal generation unit 2 is connected to both high-speed signal frequency division and speed reduction processing unit 1 and industrial computer 3. It is used to collect the signal processed by high-speed signal frequency division and speed reduction processing unit 1 and send the collected data to industrial computer 3. I / O signal generation unit 2 can be the I / O interface in PXI325 board.

[0030] The industrial control computer 3 is connected to the display screen 4 to compare the received data with the pre-stored data and display the comparison results on the display screen 4. The industrial control computer 3 develops a detection interface design unit on the display screen 4 using National Instruments CVI virtual instrument development software, and displays the detection result information on the display screen 4 through the detection interface design unit. The industrial control computer 3 can acquire signals in real time through threads, compare the acquired signals with the information pre-stored in the industrial control computer 3 to determine the high-speed channel signal detection results under the gunner's working condition or the vehicle commander's working condition, and use indicator lights on the display screen 4 to display the detection results.

[0031] like Figure 1 As shown, the above detection method includes the following steps:

[0032] Step 1 S10: The high-speed signal of the device under test 5 is obtained by the high-speed signal spread spectrum reduction processing unit of the signal detection device, and the obtained high-speed signal is sequentially divided and reduced in speed; the high-speed signal spread spectrum reduction processing unit obtains the high-speed signal of the device under test 5 through the chip, and the high-speed signal is a microsecond-level narrow pulse signal.

[0033] Step 2 S20: Use I / O signal generation unit 2 to collect data from the signal after speed reduction processing, and send the collected data to industrial control computer 3; I / O signal generation unit 2 is the I / O interface in the board.

[0034] In step three (S30), the industrial computer 3 compares the collected data with the pre-stored data and displays the comparison result on the display screen 4. During data collection, the industrial computer 3 collects data in real time via threads and uses National Instruments CVI virtual instrument development software to develop a detection interface design unit. The detection interface design unit displays the detection result on the display screen 4. The detection interface design unit can display the comparison result via indicator lights on the display screen 4.

[0035] The aforementioned high-speed signal quality detection method utilizes a high-speed signal spread spectrum reduction processing unit to acquire the high-speed signal of the device under test (DUT) 5. The acquired high-speed signal is then sequentially divided and reduced in speed. The reduced-speed signal data is then sent to the industrial control computer (ICC) 3 via the I / O signal generation unit 2. Finally, the ICC 3 compares the data and displays the detection results on the display screen 4. This high-speed signal quality detection method can be used to detect the high-speed signal quality of the DUT 5 under various extreme environments. For combat vehicles, it can simultaneously detect the high-speed signal quality under both gunner and commander conditions. Furthermore, the operation is simple and intuitive, allowing for clear and direct judgment of the high-speed signal detection results under both conditions. Therefore, this detection method can independently detect the signal quality of the output signal of the DUT 5.

[0036] In step three of the above detection method, the industrial control computer 3 collects data in real time through threads and develops the detection interface design unit through virtual instrument development software. The detection interface design unit displays the comparison results through indicator lights on the display screen 4. Since the industrial control computer 3 collects data in real time through threads, it can obtain the real-time data of the device under test 5 and can comprehensively and in real time detect the high-speed signal quality of the device under test 5. Furthermore, the results are displayed on the display screen 4 through indicator lights. The color or brightness of the indicator lights makes the detection results clear at a glance, which is convenient for the test personnel to read the detection results.

[0037] The aforementioned high-speed signal quality detection device includes a high-speed signal frequency division and speed reduction processing unit 1, an I / O signal generation unit 2, an industrial control computer 3, and a display screen 4. The high-speed signal frequency division and speed reduction processing unit 1 is used to acquire high-speed signals from the device under test 5 and sequentially perform frequency division and speed reduction processing on the acquired high-speed signals. The I / O signal generation unit 2 is used to acquire the signals processed by the high-speed signal frequency division and speed reduction processing unit 1 and send the acquired data to the industrial control computer 3. The industrial control computer 3 is signal-connected to the display screen 4 and is used to compare the received data with the pre-stored data and display the comparison results on the display screen 4. The high-speed signal quality detection device with the above structure can detect the high-speed signals of the device under test 5 and can conduct high and low temperature, shock and vibration tests on the device under test 5 separately before it is installed in the vehicle, ensuring the reliability and accuracy of the device under test 5 when it enters extreme environments such as hot and cold regions for combat operations with the whole vehicle.

[0038] The high-speed signal quality detection method and device described above can detect the high-speed signal of the device under test 5, and can simultaneously detect the high-speed signal under the gunner's working condition and the high-speed signal under the vehicle commander's working condition. The detection principle is simple and can intuitively and clearly judge the performance of the high-speed signal.
