Description

Technical Field

[0001] The present invention relates to the technical field of rail transit equipment maintenance, and in particular to a benchmarking analysis method and system for railway signal equipment maintenance operations. Background Art

[0002] As the central nervous system of railway operation, the railway signal system is responsible for the transmission of various commands and information, and is a key infrastructure to ensure the safe operation of trains. Its stability and reliability are crucial. With the continuous advancement of railway technology and the continuous increase in train speed, higher requirements are placed on the maintenance quality and efficiency of railway signal systems.

[0003] Railway electrical engineering usually conducts signal equipment inspection and maintenance work within the skylight points to inspect, maintain and repair the equipment. The above-mentioned skylight refers to the time reserved for construction and maintenance work when the train operation line is not drawn or the train operation is adjusted or reduced in the train operation diagram. During this time period, no trains pass through the blocked section of the line, and railway staff can carry out line maintenance or equipment repair work, including line renovation, replacement of damaged equipment, and disease repair.

[0004] At present, whether the maintenance process meets the standards is mainly confirmed by manually checking the monitoring data after the maintenance is completed. However, since the maintenance process involves a variety of signal equipment and a variety of maintenance items, manual confirmation alone is not only inefficient, but also difficult to ensure accuracy. If there is a situation where the equipment is missed for maintenance or is not restored to normal working condition after maintenance, it is easy to cause safety hazards and affect the safe operation of the train. Summary of the invention

[0047] The following is a further detailed description of a benchmarking analysis method and system for railway signal equipment maintenance operations proposed by the present invention in combination with the accompanying drawings and specific embodiments. According to the following description, the advantages and features of the present invention will be clearer. It should be noted that the accompanying drawings are in a very simplified form and use non-precise proportions, which are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention. In order to make the purposes, features and advantages of the present invention more obvious and easy to understand, please refer to the accompanying drawings. It should be noted that the structures, proportions, sizes, etc. illustrated in the accompanying drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the present invention, so they have no technical substantive significance. Any structural modification, change in proportional relationship or adjustment of size, without affecting the effects that the present invention can produce and the purposes that can be achieved, should still fall within the scope of the technical content disclosed by the present invention.

[0048] A first aspect of this embodiment provides a benchmarking analysis method for railway signal equipment maintenance operations, such as Figure 1 As shown, the benchmarking analysis method for railway signal equipment maintenance work includes: presetting a maintenance plan; establishing an analysis model for each maintenance item of each signal equipment according to the maintenance plan; acquiring the detection data of the signal equipment; performing a benchmarking analysis on the detection data according to the analysis model; and generating a benchmarking analysis report and an early warning prompt.

[0049] Specifically, Figure 1As shown, when presetting the maintenance plan, the staff can pre-set the following contents: maintenance start time, maintenance end time, the signal equipment to be repaired, the detection items of the signal equipment, and the standard value of the detection items. Furthermore, after the maintenance plan is pre-set, the maintenance plan can be distributed. Since the specific parameters used to analyze each maintenance item can be modified by the operator, it is convenient for the operator to set appropriate parameters according to the actual situation, fully meet the actual needs, and improve work efficiency.

[0050] Furthermore, in order to establish an analysis model for each maintenance item of each signal device, the maintenance operation can be decomposed by taking one maintenance item of one signal device as an analysis unit, and the entire maintenance operation can be decomposed into multiple analysis units. All the analysis units are stored in the analysis queue in sequence to facilitate further benchmarking analysis. By classifying maintenance operations by equipment type and maintenance content, the benchmarking analysis functions of each maintenance item are independent of each other, which is convenient for operation management and function expansion.

[0051] In order to obtain the detection data, the electrical characteristic data of the signal equipment can be collected in real time and stored through the signal centralized monitoring software during the maintenance operation. Figure 1 As shown, after acquiring the detection data, after the maintenance work is completed, multiple analysis units can be taken out according to the analysis queue, and the detection data of the detection items corresponding to each analysis unit can be subjected to benchmark analysis in turn.

[0052] More specifically, in order to achieve benchmark analysis, the test data collected during the maintenance operation can be compared and analyzed based on the standard value and other parameters set for each test item when the staff pre-sets the maintenance plan. This can determine whether the maintenance items of each signal device meet the standards, and generate the benchmark analysis report and the early warning prompt based on the analysis results, which are convenient for staff to view.

[0053] Specifically, Figure 2 As shown, the equipment that needs to be inspected and benchmarked includes three types of signal equipment, namely, turnout equipment, track equipment, and signal equipment. Each type of signal equipment includes a variety of inspection items that need to be inspected and benchmarked.

[0054] The above-mentioned turnout refers to a switch line laid at the divergence point where one track is divided into two tracks, and is used to allow locomotives and vehicles to switch from one track to another. Turnouts have two states, fixed and reverse, which are used in different situations. Generally speaking, fixed means that the turnout should remain in a position open to a certain track except for normal use, cleaning, inspection or repair, while the position open to another track is called reverse.

[0055] In order to switch the state of the turnout between the positioning and reverse positions, the turnout needs to be switched through a converter, which can be, for example, a mechanical switching device or a power switch machine. In order to check and supervise the state of the turnout and limit the turnout to a certain position (positioning or reverse position) so that it cannot be moved arbitrarily. This needs to be achieved through a lock, such as an interlock formed by buttons, relays and other electrical components. Combined with the converter and the lock, the turnout needs to go through the following process from positioning to reverse position: positioning lock → unlock → conversion (to reverse position) → reverse position lock. Similarly, the turnout needs to go through the following process from reverse position to positioning: reverse position lock → unlock → conversion (to reverse position) → positioning lock.

[0056] More specifically, if Figure 2 As shown, the maintenance of the switch equipment may include the following maintenance items: switch gap, switch friction current, switch friction power, switch operation times, switch break indication, switch action power, switch action time, switch action current and switch indication voltage. The analysis logic of each maintenance item will be specifically introduced below.

[0057] When benchmarking the turnout gap, the data of the last turnout positioning / reversal before the end of the skylight can be compared with the preset gap standard value. When the deviation between the two exceeds the preset initial value, it is judged as not meeting the standard. The above-mentioned turnout gap generally refers to the gap of the point rail on the turnout, which is mainly caused by track wear due to long-term use. The above-mentioned initial value is, for example, 0.5mm, which can be set and adjusted by the staff as needed.

[0058] When benchmarking the friction current of the turnout, the current curve of the last fixed / reversed position of the DC turnout before the end of the skylight can be compared with the pre-set standard value. When the current curve is not within the standard range, it is judged as not meeting the standard. The above-mentioned turnout friction current refers to the current generated by the converter's motor and friction connector during the turnout conversion process. If the friction current is too small, the turnout may not be converted in place; if the friction current is too large, it may cause the turnout to rebound after conversion.

[0059] When benchmarking the turnout friction power, the power curve of the last positioning / reversing of the AC turnout before the end of the skylight can be compared with the pre-set standard value. When the power curve is not within the standard range, it is judged as not meeting the standard. The above-mentioned turnout friction power refers to the power demand generated by friction between the wheelsets and the tracks on both sides of the AC turnout of the railway.

[0060] When benchmarking the number of turnout operations, the number of times the turnout set / reverse 1DQJ relay is pulled up within the skylight point can be counted. The above-mentioned 1DQJ relay, as a turnout start relay, plays the role of controlling the turnout conversion, and is usually configured with a JWJXC-H125 / 80 relay. When the number of pull-ups is less than the preset standard value, it is judged as not meeting the standard.

[0061] When performing a benchmark analysis on the switch break indication, the number of times the switch 1DQJ relay is not indicated in the positioning and reverse positions when it is energized for 30 seconds can be queried according to the start and end time set in the skylight. When the number of times no indication occurs at each traction point (from reverse position to positioning, from positioning to reverse position) is less than the preset initial value, it is judged as not meeting the standard. The above-mentioned switch break indication refers to the interruption of the switch indication circuit, which results in the inability to correctly display the status of the switch in the control room. The above-mentioned initial value is, for example, 1 time, which can be set and adjusted by the staff as needed.

[0062] When benchmarking the turnout action power, the maximum value of the last turnout fixed / reversed power curve before the end of the skylight can be taken. When the difference between the maximum value of the standard power curve set in the same direction exceeds the preset initial value, it is judged as not meeting the standard. The above-mentioned turnout action power refers to the power required by the turnout during the conversion process, which is usually analyzed and diagnosed by monitoring the power curve during the turnout action. The above-mentioned initial value is, for example, 10%, which can be set and adjusted by the staff as needed.

[0063] When benchmarking the turnout action time, the conversion time of the last turnout fixed / reverse action curve before the end of the skylight can be taken and compared with the conversion time of the standard curve set in the same direction. When the deviation between the two exceeds the preset initial value, it is judged as not meeting the standard. The above-mentioned turnout action time refers to the time required for the turnout in the conversion process, which usually depends on the specific turnout type, size and equipment used. The above-mentioned initial value is, for example, 1 second, which can be set and adjusted by the staff as needed.

[0064] When benchmarking the turnout action current, the maximum value of the last turnout fixed / reverse current curve before the end of the skylight can be taken and compared with the maximum value of the standard current curve set in the same direction. When the deviation between the two exceeds the preset initial value, it is judged as not meeting the standard. The above-mentioned turnout action power refers to the current required by the turnout during the conversion process. The above-mentioned initial value is, for example, 10%, which can be set and adjusted by the staff as needed.

[0065] When performing a benchmark analysis on the turnout indication voltage, the turnout indication voltage (AC / DC voltage of fixed / reverse position) curve of the section before the skylight ends can be taken, and the average value can be calculated and compared with the average value of the turnout standard indication voltage (AC / DC voltage of fixed / reverse position) curve. When the deviation between the two exceeds the preset initial value, it is judged as not meeting the standard. The above-mentioned turnout indication voltage refers to the voltage value used to indicate the position status of the turnout. The above-mentioned initial value is, for example, 5%, which can be set and adjusted by the staff as needed.

[0066] The above-mentioned track equipment mainly refers to track circuit equipment. Track circuit is an electrical circuit that uses two rails of the railway as conductors, rail insulation as a boundary, and uses conductors to connect signal sources and receiving devices. Track circuits can be used to reflect whether there are trains or whether the rails are intact in the line and turnout sections, which is convenient for train operation scheduling. Track circuits play an important role in railway signal automatic control systems. For example, the realization of automatic blocking is to use track circuits to transmit information about the operating status of the preceding train, and automatically command subsequent trains to run at the minimum interval, thereby improving traffic density and driving safety.

[0067] More specifically, if Figure 2 As shown, the maintenance of the track equipment may include the following maintenance items: track voltage, track phase angle, track red light band times, branch residual voltage test, ZPW-2000 main and standby switching test. The following will specifically introduce the analysis logic of each maintenance item.

[0068] When benchmarking the track voltage, the voltage curve of a section of the track circuit before the skylight ends can be taken, the average value of the voltage curve can be calculated, and compared with the standard voltage curve of the track circuit. When the deviation between the two exceeds the preset initial value, it is judged as not meeting the standard. The above track voltage is the working voltage of the track circuit. The above initial value is, for example, 10%, which can be set and adjusted by the staff as needed.

[0069] When performing benchmark analysis on the track phase angle, the phase angle curve of a section of the track circuit before the skylight ends can be taken, and the average value of the phase angle curve can be calculated. When the deviation between the two exceeds the preset initial value, it is judged as not meeting the standard. The above-mentioned track phase angle generally refers to the difference between the phase of the AC signal in the track circuit and the phase of the modulation signal. The above-mentioned initial value is, for example, 5%, which can be set and adjusted by the staff as needed.

[0070] When the number of track red light bands is analyzed, the number of track occupancy within the skylight time range can be taken and compared with the preset initial value. When the requirements are not met, it is judged as not meeting the standards. The above-mentioned track red light band is when a train passes by, the track circuit will be short-circuited, so that it will be displayed in red in the control system, indicating the location of the vehicle.

[0071] When conducting benchmark analysis on the branch residual pressure test, the lowest value of the track residual pressure test within the skylight point can be taken and compared with the preset initial value. When the lowest value of the residual pressure test is greater than the preset initial value, it is judged as not meeting the standard. The "standard branch line" is connected across the two rails that make up the track circuit, and the measured relay terminal voltage is the residual pressure of the track circuit.

[0072] When benchmarking the ZPW-2000 master-slave switch test, you can check the pickup and output voltage of the FBJ relay after the FBJ relay of the ZPW-2000 series falls within the skylight point and before the skylight point ends. When the voltage is normal, it is determined to be up to standard; otherwise, it is determined to be not up to standard. The above ZPW-2000 is the industry standard.

[0073] More specifically, if Figure 2 As shown, the maintenance of the signal equipment may include the following maintenance items: DJ current, light position opening test. The following will specifically introduce the analysis logic of each maintenance item.

[0074] The above-mentioned signal equipment mainly refers to the fixed signal on the railway that uses lights of different colors and numbers or arm positions of different colors and shapes to display command lines and shunting orders. According to different uses, the commonly used fixed signal mainly includes entry signal, exit signal, passing signal, advance signal and shunting signal.

[0075] When benchmarking the DJ current, you can take a section of the DJ current curve before the skylight ends, calculate the average value of the DJ current curve, and compare it with the DJ standard current curve. When the deviation between the two exceeds the preset initial value, it is judged as not meeting the standard. The above DJ current is the working current of the relay used by the signal. The above initial value is, for example, 5%, which can be set and adjusted by the staff as needed.

[0076] When conducting a benchmark analysis on the light position opening experiment, the signal opening status during the query period can be based on the start and end time of the skylight setting. If each light position of the signal light conducting the light position opening test is opened normally, it is judged to be up to standard; otherwise, it is judged to be not up to standard.

[0077] After benchmarking analysis of the test data of all the above-mentioned maintenance items, the benchmarking analysis report can be generated. The benchmarking analysis report can include whether each of the test items meets the standard; and analyze and record the reasons for each non-standard test item. By generating a benchmarking analysis report, it is convenient for management personnel to intuitively understand the specific situation of the maintenance work.

[0078] Furthermore, for each of the inspection items that do not meet the standards, an early warning reminder can be generated to facilitate operators to promptly discover and solve problems, further improve efficiency, and ensure the driving safety of the railway system.

[0079] In order to implement the above benchmarking analysis method, the second aspect of this embodiment provides a benchmarking analysis system for railway signal equipment maintenance operations, including an interactive interface, a detection module, a storage module and an analysis module.

[0080] Specifically, the interactive interface is used to pre-set the maintenance plan. The interactive interface can be used, for example, for any electronic device that can realize human-computer interaction, such as a mobile phone, a computer, a tablet computer, etc., for easy use by staff. Staff can input data such as the maintenance start time, the maintenance end time, the signal equipment to be repaired, the detection items of the signal equipment, and the standard values ​​of the detection items through the interactive interface to set the maintenance plan.

[0081] The detection module may be, for example, centralized signal monitoring software, which is used to collect the detection data of the signal device, for example, to collect electrical characteristic data of the signal device in real time.

[0082] The storage module is connected to the interactive interface and the detection module, and is used to store the maintenance plan input by the staff through the interactive interface and the detection data collected by the detection module. The storage module can be, for example, a volatile memory or a non-volatile memory. The volatile memory is, for example, a random access memory or a dynamic random access memory. The non-volatile memory is, for example, a read-only memory, an electrically erasable programmable read-only memory, or a hard disk drive.

[0083] The analysis module is connected to the storage module, and can be used to establish the analysis model for each maintenance item of each signal device according to the maintenance plan, and perform benchmarking analysis on the detection data according to the analysis model, and generate the benchmarking analysis report and the early warning prompt.

[0084] Specifically, the analysis module can decompose the maintenance work by taking one maintenance item of one signal device as an analysis unit, decomposing the entire maintenance work into a plurality of analysis units, and sequentially storing all the analysis units into the analysis queue.

[0085] The analysis module may take out a plurality of the analysis units according to the analysis queue, and perform benchmark analysis on the detection data of the detection item corresponding to each of the analysis units in turn.

[0086] The analysis module can also compare and analyze the detection data stored in the storage module according to the maintenance plan stored in the storage module, based on parameters such as the standard value, and generate the benchmark analysis report and the early warning prompt according to the analysis results.

[0087] The present invention sets maintenance plans in advance, so that operators can set appropriate parameters according to actual conditions, ensuring that maintenance operations and benchmarking analysis are carried out in an orderly manner. By establishing an analysis model for each maintenance item of each signal device and performing benchmarking analysis on the detection data according to the analysis model, operation management and function expansion are facilitated, the analysis efficiency is higher, and the analysis results are more accurate and precise. By generating a benchmarking analysis report after the benchmarking analysis of each maintenance operation is completed, it is convenient for managers to intuitively understand the maintenance operation status. By generating early warning prompts, it is convenient for operators to discover and solve problems in a timely manner, ensuring the driving safety of the railway system. Compared with the existing technology, it has significant progress.
