Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cable alignment device, and particularly relates to an intelligent industrial control cable alignment method and device. BACKGROUND

[0002] Generally, the structure of the alignment device has two parts of a test end and a receiving end, display lamps are arranged at the two ends, and the display lamps correspond to the channels one by one. The working principle of the prior art is that a signal is output at the test end, a signal is output at a certain channel, and the corresponding display lamp emits light. The channels of the receiving end correspond to the display lamps one by one, and when a signal is received at a certain channel of the receiving end, the display lamp corresponding to the channel emits light.

[0003] The prior art has obvious defects.

[0004] Part of the technology needs to be manually aligned one by one, which is low in efficiency; the prior art needs to manually judge the alignment of the cable according to the working condition of the display lamp; if the alignment is wrong, only manual troubleshooting is needed, and the cable needs to be connected and tested repeatedly; the prior art usually needs to connect both ends of the cable at the same time, and this method is only suitable for the alignment work of the cable in the production process (before leaving the factory) or the alignment work before the installation in the field. In fact, in the application, the two ends of the cable are usually not in the same place, and one end may be in a cabinet and the other end may be hundreds of meters away. For example, most of the signals of the DCS system in the power plant are connected from the field, and the signals of the equipment in the field are scattered in the entire plant area.

[0005] The working process of the cable field alignment and troubleshooting of the connection error is as follows: in the construction site, the alignment is usually manually performed by the alignment worker, and then a sleeve card with the same code is sleeved on both ends of the cable, the cable is laid and installed by the cable worker according to the sleeve card and the drawing, the cable is connected in the electronic room by the cable worker in the cabinet, and the cable is connected in the field by the cable worker in the field. Because the number of data points is large, alignment errors, sleeve card errors and connection errors are difficult to completely avoid. The connection error can be checked according to the information of the sleeve card, but the alignment error and the sleeve card error can only be checked manually. The checking method: at least two people are needed to cooperate, one person is at one end of the cable, the other person is at the other end of the cable, one person applies a signal to one end of the cable, and the other person detects the signal of the cable to be tested one by one using a multimeter or other detection instrument, until the signal is detected on a certain cable, and after multiple confirmations, it can be determined that the same signal cable is determined. SUMMARY

[0006] The present application aims to at least solve one of the technical problems in the related art to some extent.

[0007] Therefore, the purpose of this invention is to propose an intelligent verification method for industrial control cables, which connects the two ends of the cable to the output end and the receiving end respectively, and realizes intelligent cable matching and fault judgment by comparing the characteristic information of the signal data at both ends of the cable.

[0008] Another objective of this invention is to provide an intelligent verification device for industrial control cables.

[0009] To achieve the above objectives, this invention proposes an intelligent verification method for industrial control cables, comprising:

[0010] S1, the output end sends test signals to multiple cables under test sequentially according to a preset time interval and preset order, and acquires a first test signal data set; S2, the receiving end receives the test signals, generates detection signals, and acquires a first detection signal data set; S3, the processor preprocesses the first test signal data set and the first detection signal data set to obtain a second test signal data set and a second detection signal data set; S4, the signal output time corresponding to the output channel number in the second test signal data set is compared with the signal reception time corresponding to the receiving channel number in the second detection signal data set to obtain a matching data result; S5, based on the matching data result, multiple cables under test are detected according to preset judgment conditions and the detection result is output.

[0011] In addition, the intelligent verification method for industrial control cables according to the above embodiments of the present invention may also have the following additional technical features:

[0012] Furthermore, in one embodiment of the present invention, the parameters of the test signal include the output channel number and the signal output time; the parameters of the detection signal include the receiving channel number and the signal receiving time.

[0013] Furthermore, in one embodiment of the present invention, S4 includes: finding the comparison data value in the second test signal data set and the second detection signal data set, finding the corresponding value in the second detection signal data set, extracting the channel number corresponding to the value, and reassembling a new data set.

[0014] Further, in one embodiment of the present invention, step S4 further includes: S4.1, using the signal output time corresponding to the first output channel in the second test signal data set as the target value; S4.2, using a traversal algorithm to compare the signal reception time with the target value one by one: if the target value has no corresponding value in the second detection signal data set, an error is returned; if the target value has a corresponding value in the second detection signal data set, all corresponding channel numbers are returned; S4.3, using the signal output time corresponding to the output channel in the second test signal data set as the target value, step S4.3 is repeated until the time correspondence between all output channel numbers and receiving channel numbers is found; S4.4, the correspondence between the output channel numbers and receiving channel numbers is obtained.

[0015] Furthermore, in one embodiment of the present invention, the judgment conditions include: if the signal output time of the test signal and the signal reception time of the detection signal have a unique correspondence, then the two channels of the output end and the receiving end are connected to the same cable; if there is no corresponding detection signal at the receiving end after the test signal is output, then the channel wiring is faulty; if the signal output time of the test signal corresponds to the signal reception time of multiple channels of the receiving end, then the channel wiring is incorrect or faulty; if the signal transmission time of multiple channels of the output end is the same, then the detection device is faulty.

[0016] The intelligent verification method for industrial control cables in this invention involves an output end sending a test signal and forming a test signal parameter set, and a receiving end receiving a detection signal and forming a detection signal parameter set. By processing the test signal parameter set and the detection signal parameter set, the cable verification result is provided. This invention connects both ends of the cable to the output end and the receiving end respectively, and achieves intelligent cable matching and fault diagnosis by comparing the characteristic information of the signal data at both ends of the cable.

[0017] To achieve the above objectives, another aspect of the present invention proposes an intelligent verification device for industrial control cables, comprising: an output end and a receiving end, wherein,

[0019] The intelligent cable verification device of this invention sends a test signal at the output end and forms a set of test signal parameters, while the receiving end receives a detection signal and forms a set of detection signal parameters. By processing the test signal parameter sets and the detection signal parameter sets, the cable verification result is given. This invention connects both ends of the cable to the output end and the receiving end respectively, and achieves intelligent cable matching and fault diagnosis by comparing the characteristic information of the signal data at both ends of the cable.

[0020] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0025] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0027] The intelligent verification method and apparatus for industrial control cables according to embodiments of the present invention are described below with reference to the accompanying drawings.

[0028] Figure 1 This is a flowchart of an embodiment of the intelligent verification method for industrial control cables according to the present invention.

[0029] like Figure 1 As shown, the intelligent verification method for industrial control cables includes, but is not limited to, the following steps:

[0030] S1, the output terminal sends test signals to multiple cables under test in sequence according to a preset time interval and preset order, and obtains the first test signal data set.

[0031] Specifically, the output end sends test signals to the cable under test at preset time intervals.

[0032] As an example, the output has 12 wiring channels, labeled A1 to A12, and test signals are sent sequentially from A1 to A12 according to a preset time interval and preset order.

[0033] It is understandable that the time interval of this invention needs to take into account the influence of clock accuracy and signal transmission rate. Cable-to-line operation does not have high requirements for time accuracy, so the time can be relaxed to reduce errors and hardware costs. This invention selects 1 second, but the time interval can also be greater than 1 second.

[0034] Specifically, test signal parameters are obtained based on the test signal, including the output channel number and signal output time.

[0035] As an example, the output terminal has 12 wiring channels, labeled A1 to A12: the first channel is numbered A1, and the time when the channel sends out the test signal is X1; the second channel is numbered A2, and the time when the channel sends out the test signal is X2, and so on, assigning values ​​to the parameters of all channels. This results in a set of key-value pairs, 'a', with the output channel number as the key and the test signal output time as the value.

[0036] Therefore, the first set of test signal data obtained is a = {(“A1”, X1), ..., (“A12”, X12)}, and the output channel number and the signal output time are unique and correspond one-to-one.

[0037] S2, the receiving end receives the test signal, generates the detection signal, and obtains the first detection signal data set.

[0038] Specifically, the receiving end receives the test signal sent by the output end, generates a detection signal, and obtains the parameters of the detection signal, including: the receiving end channel number and the signal reception time.

[0039] As an example, the receiving end has a total of 12 wiring channels, labeled B1 to B12 in sequence: the first channel is numbered B1, and the time for the channel to send the test signal is Y1; the second channel is numbered B2, and the time for the channel to send the test signal is Y2, and so on, assigning values ​​to the parameters of all channels.

[0040] Obtain a set of key-value pairs, b, with the receiver channel number as the key and the detection signal reception time as the value.

[0041] Therefore, the first set of detected signal data is b = {(“B1”, Y1), ..., (“B12”, Y12)}. Under normal circumstances, the channel number of the receiving end channel and the signal detection time should be unique and correspond one-to-one. If not, there is a wiring problem.

[0042] S3, the processor preprocesses the first test signal data set and the first detection signal data set to obtain the second test signal data set and the second detection signal data set.

[0043] Specifically, after preprocessing the data, valid data is extracted based on the actual channel used.

[0044] Understandably, the data is preprocessed, and valid data from channels a and b are extracted based on the actual channels used to form the second test signal data set s and the second detection signal data set m.

[0045] Preferably, 12 test channels are set at both the output and receiving ends, but in actual work, the number of test cables may be less than 12.

[0046] For example, in actual cable usage: there are only 4 cables under test. One end of each cable is connected to output terminals A1, A2, A3, and A4, respectively, and the other end is connected to output terminals B1, B2, B3, and B4, respectively. The output test signal data is a = {(“A1”, X1), ..., (“A12”, X12)}; the receiving end detection signal data is b = {(“B1”, Y1), ..., (“B12”, Y12)}. After preprocessing by the processor, the output test signal data, which is now the second test signal data set, is s = {(“A1”, X1), (“A2”, X2), (“A3”, X3), (“A4”, X4)}; the receiving end detection signal data, which is now the second detection signal data set, is m = {(“B1”, Y1), (“B2”, Y2), (“B3”, Y3), (“B4”, Y4)}.

[0047] For example, with only four cables to be tested, one end of each cable is connected to output terminals A1, A2, A3, and A4, respectively, and the other end is connected to output terminals B1, B2, B3, and B4, respectively. After preprocessing, the resulting test data is shown in Table 1.

[0048] Table 1

[0049]

[0050] As shown in Table 1, the output test signal data is s = {(“A1”, 18:24:50), (“A2”, 18:24:51), (“A2”, 18:24:52), (“A2”, 18:24:53)}; the receiving end detection signal data is m = {(“B1”, 18:24:52), (“B2”, 18:24:50), (“B3”, 18:24:51), (“B3”, null)}.

[0051] S4. The signal output time corresponding to the output channel number in the second test signal data set is compared with the signal reception time corresponding to the receiving channel number in the second detection signal data set to obtain the matching data result.

[0052] Specifically, in the data sets s (second test signal data set) and m (second detection signal data set), the values ​​are comparison data values. The corresponding value is found in m, and the channel number corresponding to that value is extracted to reassemble a new data set. One implementation method includes, but is not limited to, the following:

[0053] Step S41: Take the signal output time corresponding to the first output channel in s as the target value.

[0054] Step S42: Compare the signal reception time with the target value one by one using a traversal algorithm:

[0055] If the target value does not have a corresponding value in m, err is returned. This indicates that the signal for that channel was not successfully transmitted or was lost, meaning there is a cable fault corresponding to that channel.

[0056] If the target value has a corresponding value in m, then return all corresponding channel numbers.

[0057] Step S43: Using the signal output time corresponding to the output channel in s as the target value, repeat step S43 until the time correspondence between all output channels and receiving channels is found.

[0058] Step S44: Determine the correspondence between the output channel and the receiving channel.

[0059] Therefore, after step S4, the following relationship can be obtained from Table 1 above:

[0060] A1 corresponds to B2; A2 corresponds to B3; A3 corresponds to B1; A4 corresponds to err

[0061] S5, based on the matching data results, detects multiple cables to be tested according to preset judgment conditions and outputs the detection results.

[0062] Specifically, based on this working principle, the output terminals sequentially send test signals at set time intervals. Under normal circumstances, the signal output times of each output terminal and the signal reception times of each input terminal are different, and the signal output time approximately corresponds to the signal reception time. Data processing is performed based on this, and the judgment conditions are as follows:

[0063] If there is a unique correspondence between the output time of a signal at a certain output terminal and the reception time of a signal at a certain channel at the receiving terminal, then these two channels are connected to the same cable.

[0064] If a signal is output from a certain output terminal but no corresponding signal is received at the receiving terminal, then the channel wiring is faulty.

[0065] If the output time of a signal at a certain output terminal corresponds to the signal reception time of multiple channels at the receiving end, then the channel wiring involved is incorrect or faulty.

[0066] If two or more channels at the signal output end emit signals at the same time, the detection equipment is faulty.

[0067] After step S5, based on the judgment conditions and the actual cable usage situation mentioned above, the following relationship is derived:

[0068] A1 corresponds to B2, and the connection between A1 and B2 is the same cable;

[0069] A2 corresponds to B3, and the connection between A2 and B3 is the same cable;

[0070] A3 corresponds to B1, and the connection between A3 and B1 is the same cable;

[0071] A4 corresponds to err, indicating an abnormal wiring issue with A4.

[0072] No signal detected at B4; B4 wiring is faulty.

[0073] Therefore, this invention mainly includes a test signal output terminal and a receiving terminal. The output terminal is used to output a test signal, which is applied to the cable under test. The test signal is sent to the receiving terminal after passing through the cable under test, and the receiving terminal detects the signal on the cable under test and generates a detection signal. Using time as a characteristic parameter, the test signal parameters include: channel number and signal output time; the detection signal parameters include: receiving terminal channel number and signal reception time. The output and input signal parameters are processed (this part is the calculation process of the processing algorithm, implemented by a software program within a centralized processor): the output and receiving channels whose signal output and reception times match are connected to the same cable; the output and input channels whose signal output and reception times do not match are faulty cables. This invention can directly provide a one-to-one correspondence between the signal output terminal and the test terminal, and determine which communication cables are faulty.

[0074] According to the intelligent verification method for industrial control cables proposed in the embodiments of the present invention, the two ends of the cable are connected to the output end and the receiving end respectively. By comparing the characteristic information of the signal data at both ends of the cable, intelligent cable matching and fault judgment are realized.

[0075] To achieve the above embodiments, such as Figure 2 The diagram shown is a structural schematic of an intelligent verification device for industrial control cables according to this embodiment. It can provide cable verification in remote, long-distance scenarios. The device includes: an output terminal 1 and a receiving terminal 2, wherein...

[0076] Output module 1001 of output terminal 1 is used to connect one end of multiple cables under test to multiple output channel interfaces of output terminal 1, and to number the multiple output channel interfaces in sequence; time interval setting module 1003 is used to set a preset time interval; first processing module 1002 is used to output instructions to output module 1001 according to the preset time interval, to send test signals to the multiple output channel interfaces in sequence, and to collect and process the test signals to generate first test data; centralized processing module 2003 is used to preprocess the first test data to obtain second test data;

[0077] The receiving module 2001 of the receiving end 2 is used to connect the other ends of multiple cables under test to multiple receiving channel interfaces of the receiving end 2, and to number the multiple receiving channel interfaces in sequence, and to receive test signals; the second processing module 2002 is used to collect and process the test signals to generate first detection data; the centralized processing module 2003 is used to preprocess the first detection data to obtain second detection data.

[0078] Specifically, output terminal 1 and receiver terminal 2 transmit data through wireless communication modules 1004 and 2004.

[0079] The following are the functions and roles of each module:

[0080] The output module 1001 can be configured with a certain number of output channel interfaces. The channel interfaces can be wire clamps or wire grooves. Those skilled in the art can set them according to actual needs. This invention does not impose specific limitations.

[0081] Assuming there are 12 output channels at output terminal 1, they are numbered A1 to A12 in sequence.

[0082] The time interval setting module 1003 is used to set the time interval.

[0083] Wireless communication modules 1004 and 2004 are used for data transmission between the output and receiving ends.

[0084] The LED display module 1005 consists of LED light groups, with each output channel corresponding to one LED light. When a channel outputs a signal, the corresponding LED light flashes.

[0085] Clock synchronization module 1006 and clock synchronization module 2006 are the same time synchronization system, which can be a GPS time synchronization system, used for time synchronization between output terminal 1 and receiver terminal 2 to ensure time synchronization.

[0086] The receiving module 2001 is equipped with a certain number of receiving channel interfaces. The channel interface can be a wire clamp. Assuming there are 12 receiving channels, they are numbered B1 to B12 in sequence.

[0087] The software program built into the centralized processing module 2003 processes and calculates the collected data, and then displays the results on the display module 2007.

[0088] The display module 2007 is a touch screen display module, and the channel in use can be selected on the 2007.

[0089] The LED display module 2005 consists of LED light groups, with one LED light corresponding to each receiving channel. When a channel receives a signal, the corresponding LED light flashes.

[0090] The specific working process of the device of the present invention will be further described below with reference to the accompanying drawings.

[0091] For the appendix Figure 2 The device described is as follows: First, one end of the cable under test is clamped onto the output terminal 1 clamp, and the other end of the cable is clamped onto the receiver terminal 2 clamp. The clock synchronization modules 1006 and 2006 synchronize the time of the output terminal 1 and the receiver terminal 2. After the time interval setting module 1003 sets the time interval, the first processing module 1002 of the output terminal 1 outputs a command to the output module 1001. The output terminal 1 sends signals to A1 to A12 in sequence, and the LEDs of the LED display module 1005 of the output terminal 1 flash in sequence. The flashing sequence of the LEDs can be used to preliminarily determine whether the test signal has been successfully transmitted. After the first processing module 1002 collects the output signal data, it transmits the data to the centralized processing module 2003 via the wireless communication module 1004. The test signal output by the output terminal 1 is transmitted to the receiver module 2001 of the receiver terminal 2 via the cable. When the receiving channel receives the signal, the corresponding LED of the LED display module 2005 flashes. The second processing module 2002 collects the signal data from the receiver 2 and sends the data from the receiver 2 to the central processing module 2003 via the wireless communication module 2004. All data is processed in the central processing module 2003 and displayed on the display module 2007.

[0092] Furthermore, such as Figure 3 The diagram shown illustrates another intelligent verification device for industrial control cables in this embodiment, suitable for close-range on-site cable verification. The device includes: an output terminal 3, a receiving terminal 4, and a terminal 5.

[0093] Figure 3 The functions of each module are as described above. Figure 2 Each module in the device has the same function and operates in the same way as the modules mentioned above.

[0094] First, clamp one end of the cable under test to the output terminal 3 clamp, and the other end of the cable to the receiver terminal 4 clamp. The clock synchronization module 5003 synchronizes the time of the output terminal 3 and the receiver terminal 4. After the time interval setting module 3003 sets the time interval, the first processing module 3002 of the output terminal 3 outputs a command to the output module 3001. The output terminal 3 sends signals sequentially to A1 to A12, and the LEDs on the LED display module 3004 of the output terminal 3 flash sequentially. The flashing sequence of the LEDs can be used to preliminarily determine whether the test signal was successfully transmitted. After collecting the output signal data, the first processing module 3002 directly transmits the data to the centralized processing module 5001. The test signal output by the output terminal 3 is transmitted via cable to the receiver module 4001 of the receiver terminal 4. When the receiving channel receives the signal, the corresponding LED on the LED display module 4003 flashes. The second processing module 4002 collects the signal data from the receiver 4 and sends the data from the receiver 4 to the centralized processing module 5001. The centralized processing module 5001 processes all the data and displays the data on the display module 5002.

[0095] With the above Figure 2 The only difference between the devices in the two systems is that: Figure 3 The data from the receiving end 4 of the device is sent directly to the centralized processing module 5001 without going through wireless communication, which means that no wireless communication module is needed.

[0096] Therefore, the device of this invention provides intelligent comparison results based on existing technology, enabling rapid matching when the number of cables to be matched is large. In addition to the basic matching function, it provides wiring anomaly alerts, indicating that the cable may be faulty. This facilitates smooth field operations and reduces the workload of staff. It overcomes the limitations of existing technologies, enabling both short-range and long-range matching.

[0097] According to an embodiment of the present invention, the intelligent verification device for industrial control cables sends a test signal at the output end and forms a set of test signal parameters, while the receiving end receives a detection signal and forms a set of detection signal parameters. By processing the set of test signal parameters and the set of detection signal parameters, the cable verification result is given. This invention connects both ends of the cable to the output end and the receiving end respectively, and achieves intelligent cable matching and fault diagnosis by comparing the characteristic information of the signal data at both ends of the cable.
