DETAILED DESCRIPTION
[0038] In order to make the purpose, features, and advantages of the present disclosure more obvious and easy to understand, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.
[0039] It should be understood that the various forms of processes shown above can be used to reorder, add or delete steps. For example, the steps recorded in this disclosure can be executed in parallel, sequentially or in different orders, as long as the desired results of the technical solution of this disclosure can be achieved, and this document is not limited here.
[0040] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present disclosure, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.
[0041] The following describes the embodiments of the present invention in conjunction with the accompanying drawings.
[0042] The current testing solution for DP cables in the industry is to use consumer-grade devices to simulate actual user usage and determine whether the DP cable is qualified based on whether the device can work normally. For example, at least one host with integrated or independent graphics and one monitor are used as consumer-grade devices, and the host and the monitor are electrically connected through a DP cable. If the DP cable can light up the monitor normally, the DP cable is qualified. If the DP cable cannot light up the monitor normally, the DP cable is unqualified.
[0043] It is understandable that the DP protocol defines 4 groups of high-speed differential signals for transmitting video signals, and each group of high-speed differential signals corresponds to a physical channel (i.e. a pair of differential lines). The DP protocol can work normally with groups 1, 2 and 4 of high-speed differential signals. At the same time, since the host may slow down when the physical link is not good, after turning on the monitor, the quality of the cable needs to be further evaluated based on the resolution of the video signal. Therefore, after using consumer-grade equipment for testing, a network analyzer is also needed to evaluate the cable quality. However, due to the high cost of network analyzers, they are usually only used in laboratories.
[0044] Please also read Figure 1 and Figure 2 , Figure 1 : shows a schematic diagram of the structure of the detection device in this embodiment, Figure 2 Shows Figure 1The present disclosure provides a detection device for detecting a target cable 20, the detection device includes a test host 11, a first interface module 12 and a second interface module 13, the test host 11 includes a host body 111 and a main control board 112, the main control board 112 is connected to the host body 111 and is configured with a data analysis module 113, the first interface module 12 includes a first interface board 121, the first interface board 121 is connected to the host body 111 and is configured with a signal receiving module 122, the first interface board 121 The second interface module 13 is electrically connected to the main control board 112, and one end of the target cable 20 is electrically connected to the first interface board 121. The second interface module 13 includes a second interface board 131, and the second interface board 131 is configured with a signal generating module 132, and the other end of the target cable 20 is electrically connected to the second interface board 131. The signal generating module 132 is used to generate a test signal, and the test signal is transmitted to the signal receiving module 122 after passing through the target cable 20. The signal receiving module 122 sends the received test signal to the data analysis module 113, and the data analysis module 113 is used to analyze and calculate the test signal to detect the line loss and communication quality of the target cable 20. Exemplarily, the target cable 20 can be a DP cable (i.e., a digital signal cable) in a laptop computer.
[0045] When the above-mentioned detection device is used for detection, first, one end of the target cable 20 is electrically connected to the first interface board 121, and the other end of the target cable 20 is electrically connected to the second interface board 131. Then, a test signal is generated by the signal generating module 132 configured on the second interface board 131. The test signal is transmitted to the signal receiving module 122 after passing through the target cable 20. Finally, the data analysis module 113 configured on the main control board 112 obtains the test signal received by the signal receiving module 122, and analyzes and calculates the test signal to realize the detection of the communication quality and cable loss of the target cable 20 at the same time. In this way, the communication quality and cable loss of the target cable 20 can be detected by one device, thereby improving the detection efficiency on the basis of reducing the detection cost.
[0046] See also Figure 2In some embodiments, the signal generating module 132 includes a signal generating element 1321 and a DC module 1322 (DC module power supply), the signal generating element 1321 is used to generate a code stream signal, and the DC module 1322 is used to generate a level signal, and the code stream signal and the level signal are both test signals; the signal receiving module 122 includes a signal receiving element 1221 and an AD sampling module 1222, the signal receiving element 1221 receives the code stream signal through the target cable 20, the AD sampling module 1222 is used to load the target cable 20 and sample the level before and after the loading, the data analysis module 113 is used to calculate the bit error rate of the code stream signal to detect the communication quality of the target cable 20, and the data analysis module 113 is also used to calculate the line loss according to the sampling result of the AD sampling module 1222.
[0047] In this embodiment, when the target cable 20 is subjected to line loss detection, a predetermined electrical level is provided to the target cable 20 through the DC module 1322. After power supply is detected, the target cable 20 is loaded through the AD sampling module 1222, and the electrical levels before and after loading are sampled. The data analysis module 113 calculates the line loss value of the target cable 20 according to the electrical levels before and after loading according to the AD sampling module 1222 to obtain the actual line loss value, and determines whether the cable quality is qualified according to the line loss threshold configured for the target cable 20. When the actual line loss value is less than the line loss threshold, it indicates that the line loss of the target cable 20 is qualified. When the actual line loss value is greater than or equal to the line loss threshold, it indicates that the line loss of the target cable 20 is unqualified.
[0048] Please also read Figure 3 and Figure 4 , Figure 3 FIG. 1 shows a flowchart of the communication quality detection of the target cable 20 in the embodiment of the present disclosure. Figure 4 A schematic diagram of sampling the original code stream and the superimposed code stream in an embodiment of the present disclosure is shown, wherein the horizontal axis direction is the sampling time, and the vertical axis direction is the sampling level. In this embodiment, when the communication quality of the target cable 20 is detected, the communication quality of the target cable 20 is detected by the data analysis module 113, and the data analysis module 113 samples the detection signal received by the signal receiving module 122, and calculates the bit error rate of the sampled detection signal.
[0049] Furthermore, the signal generating element 1321 is a code generator, which generates a code stream. Correspondingly, the code stream signal is a test signal. After the code stream passes through the target cable 20, the vertical offset and the horizontal offset are superimposed in sequence at the signal receiving element 1221 and then deserialized to obtain the offset code stream.
[0050] Please continue to see Figure 5 , Figure 5A sampling diagram of an offset code stream in an embodiment of the present disclosure is shown, wherein the horizontal axis is the sampling time and the vertical axis is the sampling level. Further, the offset code stream is sampled, and the signal sampling module 114 performs offset sampling in two directions on the code stream received by the signal receiving module 122. When offset sampling in the horizontal direction (i.e., the time direction), the signal sampling module 114 advances or delays in the horizontal direction based on the conventional sampling point p0 and generates the horizontal coordinate of the sampling. When offset sampling in the vertical direction (i.e., the level direction), the signal sampling module 114 offsets upward or downward in the vertical direction based on the conventional sampling point p0 and generates the vertical coordinate of the sampling, thereby obtaining the sampling point P1; then, the signal sampling module 114 performs multiple samplings at the sampling points offset in the horizontal direction and the vertical direction, and transmits the position of each sampling point and the sampling result to the data analysis module 113.
[0051] Furthermore, the received original signal is deserialized to obtain the original code stream. The data analysis module 113 calculates the bit error rate by comparing the offset code stream and the original code stream. Specifically, the signal sampling module 114 compares the offset code stream sampled at each sampling point with the original code stream at the sampling point. When the offset code stream is different from the original code stream, the code stream at the sampling point is a bit error. After the signal sampling module 114 samples at multiple sampling points, the data analysis module 113 calculates the ratio of the number of bit errors N1 to the total number of samples N of the signal sampling module 114, which is the bit error rate.
[0052] In this embodiment, the data analysis module 113 generates a two-dimensional matrix diagram of bit error rate distribution according to the sampling positions, and determines whether the detection signal is qualified according to the two-dimensional matrix diagram of bit error rate distribution.
[0053] In this embodiment, the data analysis module 113 further renders the generated two-dimensional matrix into a digital eye diagram, so as to more intuitively detect the communication quality of the target cable 20 .
[0054] Furthermore, by interconnecting with the computer interface through software, the generated bit error rate is mapped into a colorful picture (i.e., a digital eye diagram) according to a certain correspondence between the bit error rate and the color. The closer to the center area, the smaller the superimposed interference (horizontal offset and vertical offset), so the smaller the bit error rate. Therefore, the anti-interference situation of the signal is reflected by the entire eye diagram. The larger the center area, the better the signal quality.
[0055] In this way, since the detection process of the network analyzer is complicated and the detection cost is high, the communication quality of the target cable is usually only sampled in the laboratory. Therefore, the detection method of the communication quality of the target cable in the present application replaces the existing network analyzer, so as to realize the detection of each target cable, improve the detection quality, and reduce the detection cost.
[0056] It can be understood that the principle of generating a digital eye diagram based on a bit error rate is the same as the eye diagram generation principle of a traditional network analyzer and is a prior art.
[0057] In some embodiments, the signal generating component 1321 includes a high-speed signal generator and a low-speed signal generator configured on the second interface board 131, the high-speed signal generator is used to generate a high-frequency code stream signal, and the low-speed signal generator is used to generate a low-frequency code stream signal; the signal receiving component 1221 includes a high-speed signal receiver and a low-speed signal receiver configured on the first interface board 121, the high-speed signal receiver is used to receive the high-frequency code stream signal generated by the high-speed signal generator, and the low-speed signal receiver is used to receive the low-frequency code stream signal generated by the low-speed signal generator.
[0058] In this way, by configuring a high-speed signal generator and a low-speed signal generator to generate a high-frequency code stream signal and a low-frequency code stream signal, the communication quality of the target cable 20 through the low-frequency signal and the communication quality of the target cable 20 through the high-frequency signal can be detected at the same time, thereby improving the detection accuracy of the communication quality of the target cable 20.
[0059] In some embodiments, the target cable 20 is integrated with electronic components, and the main control board 112 is also configured with a main control chip, and the main control chip is provided with a field programmable gate array, and the main control chip provided with a field programmable gate array is used to detect the electronic components on the target cable 20. Exemplarily, the electronic components integrated on the target cable 20 can be sensors, microphones, and LED lights.
[0060] See also Figure 6 , Figure 6 The schematic diagram of the structure of the circuit for disconnection detection and short circuit detection in the embodiment of the present disclosure is shown. In some embodiments, the second interface board 131 is further configured with a first switch network 17, a power supply 15 and a measuring component 16. The power supply 15 and the first network switch are connected in series. The second interface board 131 is further configured with a second network switch 18. One end of the target cable 20 is electrically connected to the first switch network 17 through the second interface board 131, and the other end of the target cable 20 is electrically connected to the second network switch 18 through the first interface board 121. The measuring component 16 is electrically connected to the target cable 20 and is used to measure the signal of the target cable 20. The target cable 20 includes a plurality of sub-wires 21, one end of each sub-wire 21 is electrically connected to the measuring component 16 through the first switch network 17, and the other end of each sub-wire 21 is grounded through the second network switch 18. Exemplarily, the power supply 15 can be a battery, and the electrical signal can be a voltage or a current; specifically, the number of sub-wires 21 of the target cable 20 is more than two.
[0061] During the circuit break detection, one end of one of the sub-wires 21 is closed through the first switch network 17 to connect one end of the sub-wire 21 to the power supply 15, and the other end of the sub-wire 21 is closed through the second switch network to ground the other end of the sub-wire 21; then, after the power supply 15 applies voltage, when the electrical signal of the target cable 20 detected by the measuring device 16 is zero, the sub-wire 21 is broken; finally, the two ends of the other sub-wires 21 are closed through the first switch network 17 and the second switch network, and the electrical signal of the corresponding sub-wire 21 to be tested is measured through the measuring device 16 to detect whether the other sub-wires 21 to be tested are broken.
[0062] During short circuit detection, first, one end of one of the sub-wires 21 is closed through the first switch network 17, and the other end of the other sub-wire 21 is closed through the second switch network. Then, after voltage is applied through the power supply 15, when the electrical signal of the target cable 20 detected by the measuring component 16 is greater than zero, a short circuit occurs between the two sub-wires 21. Finally, the above steps are repeated to perform short circuit detection on any other two sub-wires 21.
[0063] In this way, by integrating the detection of open circuit and short circuit of the target cable 20 into the detection device, more functional detection can be achieved through one detection device, further reducing the detection cost and improving the detection efficiency. At the same time, the detection circuit is simple and the detection accuracy is high.
[0064] Furthermore, this embodiment can also realize the detection of micro short circuits.
[0065] In some embodiments, the measuring component 16 is a current measuring component 161, which is connected in series with the target cable 20 and is used to detect the current signal of the target cable 20. Specifically, the voltage source, the current measuring component 161 and the target cable are connected in series; or / and, the measuring component 16 is a pressure measuring component 162, which is connected in parallel with the target cable 20 and detects the voltage of the target cable 20. Exemplarily, the current measuring component 161 can be an ammeter, and the pressure measuring component 162 can be a voltmeter.
[0066] In some embodiments, the power supply 15 includes a first voltage source 151 and a second voltage source 152, both of which are electrically connected to one end of the target cable 20 through the first switch network 17, and the output voltage of the first voltage source 151 is greater than the output voltage of the second voltage source 152. Specifically, the first voltage source 151 is a high voltage power source, for example, the power of the first voltage source 151 is greater than 200V, and the second voltage source 152 is a normal power source, that is, the rated voltage of the target cable 20 when working, for example, the voltage of the second voltage source 152 is 5V.
[0067] In this way, by providing voltage sources with different output voltages, it is possible to detect the open circuit and the open circuit of the target cable 20 in two working environments, thereby further improving the detection accuracy.
[0068] Please continue reading Figure 1 In some embodiments, the detection device further includes a vibration platform 14 , and the second interface board 131 is connected to the vibration end of the vibration platform 14 , and the vibration platform 14 is used to drive the second interface board 131 to vibrate, so as to detect poor welding of the target cable 20 .
[0069] In this way, during the detection process, the target cable 20 is always in a vibrating state. When the welding is poor, the internal solder joints of the target cable 20 are loose and cause poor contact, so that during the detection process, it is possible to determine whether the contact is poor by detecting whether the signal is on or off. For example, when the communication quality of the target cable 20 is detected, when the signal receiving component 1221 cannot receive the code stream signal, it means that the solder joints on the target cable 20 corresponding to the communication quality detection have poor welding. When the target cable 20 is detected for line loss, when the AD sampling module 1222 cannot obtain the sampling signal, it means that the solder joints on the target cable 20 corresponding to the cable loss detection have poor welding. When the electronic components integrated on the target cable 20 are detected, when the main control board 112 cannot obtain the electrical signal of the corresponding electronic components, it means that the solder joints on the target cable 20 corresponding to the electronic component detection have initially shown poor welding. Therefore, it is possible to more accurately detect that the specific solder joints are loose, thereby improving the accuracy of detecting poor welding.
[0070] It is understandable that the existing target cable 20 is judged by human eyes whether there is a poor welding, and the detection accuracy is poor.
[0071] In some embodiments, the vibration platform 14 is a separate vibrator, so that the vibration plate of the vibration platform 14 can be disassembled and removed from the vibration screen, so that the second interface board 131 can be flexibly installed on the vibration plate of the vibration platform 14. Specifically, the vibration platform 14 includes a vibrator body, a plurality of vibration columns and a vibration plate, the vibrator body is connected to the plurality of vibration columns, the plurality of vibration columns are arranged at intervals and detachably connected to the vibration plate, the vibrator body drives the plurality of vibration columns to vibrate, the plurality of vibration columns drive the vibration plate to vibrate, and the vibration plate drives the target cable 20 to vibrate through the second interface board 131.
[0072] Furthermore, the second interface plate 131 is fixed to the vibration plate of the vibration platform 14 by screws.
[0073] In some embodiments, the host body 111 includes a shell 1111, a display panel 1112 and an operation button 1113, the main control board 112 is housed inside the shell 1111, the display panel 1112 is embedded in one side of the shell 1111 and is electrically connected to the main control board 112, and the operation button 1113 is embedded in a position on the shell 1111 adjacent to the display panel 1112 and is electrically connected to the main control board 112.
[0074] In this way, the display panel 1112 is electrically interconnected with the main control board 112, and the generated bit error rate is mapped into a color diagram (i.e., a digital eye diagram) according to a certain correspondence between the bit error rate and the color, so that the signal quality of the target cable 20 can be observed more intuitively, and the detection operation can be performed through the operation button 1113, making the detection more convenient. At the same time, the internal electronic components can be stored and protected by the shell 1111. The above is only a specific implementation of the present disclosure, but the protection scope of the present disclosure is not limited to this. Any technician familiar with the technical field can easily think of changes or replacements within the technical scope disclosed in the present disclosure, which should be covered within the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure shall be based on the protection scope of the claims.
