Technical Field

[0001] The invention belongs to the field of online monitoring, and in particular relates to an online monitoring system for contact network compensation. Background Art

[0002] The catenary compensation online monitoring system is an important part of the railway electrification system. It is used to monitor the state and performance of the catenary to achieve real-time monitoring and fault diagnosis of the catenary compensation device. This system is based on the combination of modern information technology and sensor technology, which can realize online monitoring of the catenary compensation device and help improve the safety and stability of the railway electrification system.

[0003] The railway electrification system is an important part of modern railway transportation, and its stability and safety are crucial to the normal operation of railway transportation. The overhead contact network is a key equipment in the railway electrification system, which directly affects the power supply quality and operation efficiency of the electrification system. In order to ensure the normal operation of the overhead contact network, it is necessary to monitor and diagnose faults in real time. However, the traditional monitoring method mainly relies on manual inspection and regular maintenance, which has problems such as low monitoring efficiency and inaccurate monitoring data, and cannot meet the needs of modern railway electrification systems for overhead contact network status monitoring.

[0004] The shortcomings of the existing technology mainly include the following aspects: Traditional monitoring methods rely on manual inspections and regular maintenance, and the monitoring efficiency is low. Manual inspections require a lot of manpower and material resources, and are easily affected by human factors, and the accuracy of monitoring data cannot be guaranteed. There are difficulties in acquiring and processing monitoring data. Traditional monitoring methods cannot achieve real-time monitoring of the contact network status and online processing of data, and there are certain difficulties in acquiring and processing monitoring data. The fault diagnosis capability is limited. Traditional monitoring methods can often only detect faults in the contact network, but cannot accurately diagnose the specific cause and location of the fault. The monitoring capability of the contact network compensation device is limited. Traditional monitoring methods can often only monitor the basic status of the contact network, and the monitoring capability of the contact network compensation device is limited.

[0005] Therefore, in order to solve the problems existing in the existing technology, it is necessary to introduce a new online monitoring system for catenary compensation. This system can realize real-time monitoring of the catenary compensation device through sensor technology, and realize real-time processing and analysis of monitoring data through modern information technology, thereby realizing real-time monitoring and fault diagnosis of the catenary status. This system can effectively improve the safety and stability of the railway electrification system, which is of great significance for ensuring the normal operation of railway transportation. Summary of the invention

[0006] The present invention proposes an online monitoring system for contact network compensation, which solves the problem that the online monitoring system for contact network compensation in the prior art realizes real-time monitoring of the state of contact network equipment through laser ranging and temperature acquisition modules, and performs data feedback and alarm processing through a communication interaction module and a state monitoring module, thereby solving the problems of low efficiency, difficulty in data acquisition, and limited fault diagnosis capability of traditional monitoring methods.

[0007] The technical solution of the present invention is implemented as follows: an online monitoring system for overhead line compensation includes a laser ranging module, a temperature acquisition module, a communication interaction module, a state monitoring module and an energy supply module for data interaction;

[0008] The laser distance measurement module measures the distance of the contact network monitoring equipment in the scene based on the image data collected by the contact network equipment, marks the relative positions of the contact network monitoring equipment in the scene, builds a scene marking map, and feeds the scene marking map back to the status monitoring module through the communication interaction module;

[0009] The temperature acquisition module collects the ambient temperature of the monitoring contact network compensation equipment in real time when it is working, retrieves the scene marking map in the laser ranging unit, associates the distance data with the ambient temperature through the scene marking map, and forms temperature range attenuation step data according to the associated data; then feeds the temperature range attenuation step data back to the status monitoring module through the communication interaction module;

[0010] The communication interaction module defines a preset area, receives signals from the laser ranging module and the temperature acquisition module in the preset area, divides the received signals according to the area, classifies the collected signals according to the divided area, and feeds back the collected signals to the status monitoring module in sequence according to the divided area;

[0011] The state monitoring module collects data from all laser ranging modules and temperature acquisition modules in a preset area through a communication interaction module, sorts the ambient temperature change data according to time, displays the sorted data, and sets a warning threshold in the state monitoring module. When the data collected in any area exceeds the warning threshold, an alarm is sent to the background server;

[0012] The energy supply modules are arranged in an array in a preset area to supply energy to the laser ranging module, the temperature acquisition module and the communication interaction module.

[0013] The differences between this contact network compensation online monitoring system and the existing technology are mainly reflected in the following aspects: the traditional contact network monitoring system can usually only monitor the static state of the equipment, while this system realizes real-time monitoring of the contact network equipment state through the laser ranging module and the temperature acquisition module. The laser ranging module can measure the distance within the scene of the image data collected by the contact network equipment, and construct a scene marking map to realize dynamic monitoring. The temperature acquisition module can collect the ambient temperature during operation in real time, associate the distance data with the ambient temperature, and form the temperature range attenuation ladder data, thereby realizing real-time monitoring of ambient temperature changes. The improvement of these real-time monitoring capabilities enables the system to capture and respond to the state changes of the contact network equipment more promptly.

[0014] The communication and interaction module of this system defines a preset area, in which the signals of the laser ranging module and the temperature acquisition module can be received, and the area division and signal classification are performed, and then the feedback is fed back to the status monitoring module. Such intelligent data processing method enables the system to process a large amount of monitoring data more effectively, and classify, integrate and analyze the data, so as to better realize the monitoring and analysis of the state of the contact network equipment. The warning threshold is set in the status monitoring module. Once the data in any area exceeds the warning threshold, an alarm can be sent to the background server. This alarm mechanism can help operation and maintenance personnel to find problems in time and take corresponding measures to avoid equipment failure or safety risks. In addition, the energy supply module of the system is arranged in an array in the preset area to supply energy to the laser ranging module, the temperature acquisition module and the communication and interaction module, making the energy supply of the system more stable and reliable. Compared with traditional technologies, the online monitoring system of contact network compensation has significantly improved in real-time monitoring capabilities, intelligent degree of data processing and feedback, alarm and energy supply. These improvements and optimizations enable the system to better meet the real-time monitoring and management needs of contact network equipment, improve the accuracy and timeliness of monitoring, and help improve the safety and efficiency of railway transportation.

[0015] As a preferred embodiment, the energy supply module adopts a lithium ion battery for energy supply. The rated voltage of the lithium ion battery is 3.6V, the capacity of the lithium ion battery is 35000mAh, and the continuous current it supplies to the communication interaction module, the temperature acquisition module, and the laser ranging unit is 400mA.

[0016] As a preferred embodiment, the range of the laser ranging module is 0.03 to 10 m. By measuring the distance between the laser ranging unit and the contact network compensation equipment within the range, the measurement accuracy is controlled within ±2 mm, the working voltage is 5-24 V, and the working current is 36 mA.

[0017] As a preferred embodiment, the temperature range attenuation step data of the temperature acquisition module is provided with step data values ​​above and below the standard temperature range value. When the temperature exceeds or falls below the standard temperature range value, the area around the laser ranging unit is marked and recorded, and the time, area and temperature data are recorded, and the recorded data is fed back through the communication interaction module.

[0018] After adopting the above technical scheme, the beneficial effect of the present invention is that the system can monitor the state of the contact network equipment in real time, including parameters such as distance and ambient temperature. Once an abnormal situation is found, the system can issue an alarm in time to help the operation and maintenance personnel to respond quickly, thereby reducing potential safety hazards and improving the safety and reliability of railway transportation. Through real-time monitoring and intelligent data analysis, the system can help operation and maintenance personnel better understand the state and operation of the equipment, help to find problems in advance and perform preventive maintenance, reduce maintenance costs, and extend the service life of the equipment. Since the system can monitor the state of the contact network equipment in real time, find problems in time and take measures, it can reduce transportation interruptions caused by equipment failures or abnormal situations, ensure the stability and continuity of the transportation line, and improve transportation efficiency. Through intelligent data processing and sorting and storage of status monitoring modules, the system can provide a large amount of equipment status data for the railway transportation management department, which is conducive to data analysis and decision support, and helps optimize equipment maintenance plans, improve equipment layout and optimize transportation route planning. The energy supply module of the system is set in a preset area, which can provide a stable energy supply to the monitoring module, ensure the normal operation of the monitoring equipment, and reduce monitoring interruptions or data loss caused by energy problems. The introduction of the online monitoring system for catenary compensation will bring many benefits to the railway transportation system, including improving safety, reducing maintenance costs, improving transportation efficiency, providing data support and ensuring the stability of energy supply, etc. These benefits will help improve the overall operation quality and efficiency of the railway transportation system.

[0022] Example:

[0023] like Figure 1 As shown, a contact network compensation online monitoring system includes a laser ranging module, a temperature acquisition module, a communication interaction module, a status monitoring module and an energy supply module for data interaction;

[0024] The laser distance measurement module measures the distance of the contact network monitoring equipment in the scene based on the image data collected by the contact network equipment, marks the relative positions of the contact network monitoring equipment in the scene, builds a scene marking map, and feeds the scene marking map back to the status monitoring module through the communication interaction module;

[0026] The communication interaction module defines a preset area, receives signals from the laser ranging module and the temperature acquisition module in the preset area, divides the received signals according to the area, classifies the collected signals according to the divided area, and feeds back the collected signals to the status monitoring module in sequence according to the divided area;

[0027] The state monitoring module collects data from all laser ranging modules and temperature acquisition modules in a preset area through a communication interaction module, sorts the ambient temperature change data according to time, displays the sorted data, and sets a warning threshold in the state monitoring module. When the data collected in any area exceeds the warning threshold, an alarm is sent to the background server;

[0028] The energy supply modules are arranged in an array in a preset area to supply energy to the laser ranging module, the temperature acquisition module and the communication interaction module.

[0029] This online monitoring system for catenary compensation includes a laser ranging module, a temperature acquisition module, a communication interaction module, a status monitoring module, and an energy supply module. These modules interact with each other to achieve real-time monitoring and data analysis of the catenary equipment. The following is a detailed explanation of its working principle and workflow, as well as the differences and advantages:

[0030] Laser ranging module: This module is mainly used to measure the distance of the contact network equipment. By collecting image data and building a scene marking map, the data is fed back to the status monitoring module through the communication interaction module. This method can accurately mark and monitor the location of the contact network equipment, thereby providing high-precision data support.

[0031] Temperature acquisition module: This module is used to collect the ambient temperature of the overhead line compensation equipment in real time, and associate the temperature data with the scene marker map in the laser ranging module to form temperature range attenuation ladder data. This design can help the system better understand the impact of temperature changes on the equipment and provide more comprehensive monitoring and analysis.

[0032] Communication interaction module: This module is responsible for defining the preset area, receiving the signals from the laser ranging module and the temperature acquisition module, and then classifying and dividing the signals into areas, and feeding back the collected signals to the status monitoring module. In this way, the system can process and monitor the data of different areas separately, improving the flexibility and real-time performance of the system.

[0033] Status monitoring module: This module collects data from all modules and sorts, stores and displays ambient temperature change data. At the same time, a warning threshold is set in the status monitoring module. Once the collected data exceeds the warning threshold, the system will send an alarm to the background server. This design can help to discover and solve problems in a timely manner and ensure the safety and stability of the system.

[0034] Energy supply module: This module is set up in the preset area and provides energy supply to other modules to ensure the normal operation of each module. Such a design can ensure the stability and reliability of the system. The advantage of this system is that it comprehensively utilizes a variety of technical means such as laser ranging, temperature collection and communication interaction to achieve all-round monitoring and data analysis of contact network equipment. At the same time, the system adopts intelligent data processing and warning mechanisms, which can timely discover and solve problems and ensure the safety and stability of railway transportation. The difference of this system is that it comprehensively utilizes a variety of technical means and realizes data interaction between modules, which improves the monitoring accuracy and real-time performance of the system. The contact network compensation online monitoring system has the characteristics of all-round, high-precision and real-time performance, and can provide reliable monitoring and data support for the railway transportation system.

[0035] The energy supply module uses lithium ion battery for energy supply. The rated voltage of the lithium ion battery is 3.6V, the capacity of the lithium ion battery is 35000mAh, and the continuous current of the lithium ion battery for energy supply to the communication interaction module, the temperature acquisition module, and the laser ranging unit is 400mA. Compared with the prior art, the energy supply unit uses lithium ion battery for energy supply. This is significantly different from the traditional energy supply method, which may use battery packs, storage batteries or directly use AC power supply. The difference of using lithium ion battery for energy supply is mainly reflected in the following aspects: lithium ion battery has a higher energy density. Compared with traditional lead-acid batteries or nickel-metal hydride batteries, it can provide more electrical energy at the same volume, so it can power the monitoring system for a longer time. Lithium ion battery is relatively light, easy to carry and replace, which is very important for monitoring systems that need to be moved or flexibly arranged. Lithium ion battery has a long service life, many charge and discharge cycles, can provide stable energy supply, and reduce the frequency of battery replacement and maintenance costs.

[0036] The main reasons for using lithium-ion batteries for power supply include their high energy density and lightweight characteristics. This setting can ensure that the monitoring system can operate stably for a long time, reduce the frequency of battery replacement and maintenance costs, and also improve the flexibility and portability of the system.

[0037] The use of lithium-ion batteries for energy supply is mainly reflected in ensuring the stability and durability of the monitoring system. Since lithium-ion batteries have high energy density and long life, they can continuously provide stable power to the monitoring system, ensuring that the system can operate stably for a long time, reducing downtime caused by battery replacement, and improving the reliability and sustainability of the monitoring system. The decision to use lithium-ion batteries for energy supply is based on its high energy density, light weight and long life. Such a setting can ensure the stability and durability of the monitoring system, reduce maintenance costs, and improve the flexibility and reliability of the system.

[0038] The range of the laser ranging module is 0.03 to 10m. By measuring the distance between the laser ranging unit and the contact network compensation device within the range, the measurement accuracy is controlled within ±2mm, the working voltage is 5-24V, and the working current is 36mA. Compared with the prior art, the range of the laser ranging module is wider and can achieve a ranging range of 0.03 to 10m. Under the same range, its measurement accuracy is controlled within ±2mm, the working voltage is 5-24V, and the working current is 36mA.

[0039] This is significantly different from the traditional laser ranging module, which may have certain limitations in terms of ranging range, measurement accuracy and operating voltage. With such a laser ranging module, its wider range can meet the measurement needs of more different distances, making the monitoring system more flexible and versatile. Secondly, the higher measurement accuracy can ensure the accurate measurement of the spacing between the contact network compensation devices and ensure the accuracy of the data. In addition, the wide operating voltage range is suitable for different power supply environments, which improves the applicability and stability of the system.

[0040] The role of the laser ranging module set up in this way is mainly reflected in providing a wider range and higher measurement accuracy, which can meet the needs of different distance measurements and ensure the accuracy of the measurement data. At the same time, the wide operating voltage range also improves the applicability and stability of the system. The laser ranging module adopts a wider range, higher measurement accuracy and a wide operating voltage range. Such a setting can meet the needs of different distance measurements, ensure the accuracy of the measurement data, and improve the applicability and stability of the system.

[0041] The temperature range attenuation step data of the temperature acquisition module is set with step data values ​​above and below the standard temperature range value. When the temperature exceeds or falls below the standard temperature range value, the laser ranging unit is marked and recorded around it, and the time, area and temperature data are recorded, and the recorded data is fed back through the communication interaction module. Compared with the prior art, the temperature acquisition module has more intelligent characteristics. Its temperature range attenuation step data setting can achieve step data values ​​above and below the standard temperature range value. When the temperature exceeds or falls below the standard temperature range value, the laser ranging unit is marked and recorded around it, and the time, area and temperature data are recorded, and the recorded data is fed back through the communication interaction module. This is significantly different from the traditional temperature acquisition module, which may only provide temperature values, and has limited recording and feedback functions when the temperature exceeds or falls below the standard range.

[0042] By setting step data values ​​above and below the standard temperature range, the temperature changes can be monitored more accurately, and the temperature exceeding or falling below the standard range can be discovered in time. Secondly, by marking and recording around the laser ranging unit and providing feedback through the communication interaction module, abnormal conditions can be recorded in time and the data can be fed back to the monitoring system to ensure that appropriate measures are taken in time. The role of the temperature acquisition module set up in this way is mainly reflected in providing a more intelligent temperature monitoring function, which can record abnormal conditions in time and feed them back to the monitoring system to ensure the safety and stability of the system. At the same time, more accurate temperature monitoring also helps preventive maintenance and troubleshooting of the system. The temperature acquisition module adopts a more intelligent temperature monitoring function, which can record abnormal conditions in time and feed them back to the monitoring system to ensure the safety and stability of the system. Such a setting can provide more accurate temperature monitoring and help preventive maintenance and troubleshooting of the system.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
