Technical Field

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

[0002] Catenary compensation online monitoring equipment refers to the compensator equipment used to monitor the railway catenary. The catenary is an important part of the railway electrification system. It provides power to the train and is an important infrastructure for railway transportation. The catenary compensator is used to adjust the tension of the catenary to ensure that the catenary can maintain a stable position and tension when the train passes, thereby ensuring the normal operation of the train.

[0003] Disadvantages of the existing technology: Traditional monitoring methods for overhead line compensators mainly rely on manual inspections and regular maintenance, which have the following disadvantages: Manual inspections require a lot of manpower and time, are costly and inefficient. Moreover, the results of manual inspections are affected by human factors, and the accuracy and reliability of monitoring data cannot be guaranteed. Regular maintenance is prone to problems such as missed inspections and false inspections, and it is impossible to detect faults and problems of the overhead line compensator in a timely manner, which can easily cause safety hazards. Traditional monitoring methods cannot achieve real-time monitoring and remote management of overhead line compensators, and it is difficult to respond in a timely manner and provide fault warnings.

[0004] Therefore, the existing overhead line compensator monitoring technology has problems such as inaccurate monitoring, high maintenance cost, and great safety hazards. A new monitoring device is urgently needed to solve these problems. In order to solve the shortcomings of the existing technology, a new type of overhead line compensation online monitoring equipment has emerged. This equipment adopts advanced sensing technology and Internet of Things technology, which can realize real-time monitoring and remote management of the overhead line compensator. The equipment can monitor the tension, displacement, temperature and other parameters of the overhead line compensator in real time, and transmit the monitoring data to the monitoring center for real-time analysis and processing. Once the overhead line compensator is found to be abnormal, the system can issue an early warning signal in time to notify relevant personnel to handle it, thereby avoiding the occurrence of safety accidents. In addition, the new type of overhead line compensation online monitoring equipment can also realize remote management. Operators can remotely monitor and manage the overhead line compensator through the Internet without on-site inspection, which greatly reduces the workload and cost of maintenance personnel. The new type of overhead line compensation online monitoring equipment can effectively solve the shortcomings of the existing technology, improve the monitoring accuracy and reliability of the overhead line compensator, reduce maintenance costs, and improve the safety and stability of railway transportation. Therefore, the equipment has important application prospects in railway electrification systems. Summary of the invention

[0005] The present invention proposes an online monitoring device for contact network compensation. The online monitoring device for contact network compensation monitors the temperature change and distance of the contact network compensator in real time through a temperature sensor and a laser ranging unit, and controls the heating value of the lithium-ion battery through associated data, thereby solving the technical problems of insufficient accuracy and real-time performance of traditional monitoring methods.

[0006] The technical solution of the present invention is implemented as follows: an online monitoring device for contact network compensation, including a temperature sensor and a laser ranging unit arranged on the front end face of a cast aluminum shell, a communication antenna arranged on the rear end face of the cast aluminum shell, and a control unit and a lithium-ion battery arranged in the inner cavity of the cast aluminum shell. The laser ranging unit adopts a high-precision laser sensor, and monitors the temperature change of the contact network compensation device during operation through the temperature sensor, and sends the monitored temperature change to the control unit. The control unit receives the temperature change data and sorts it according to time for storage, and obtains the temperature by measuring the distance and the ambient temperature according to the distance between the laser ranging unit and the contact network compensation device. Attenuation step data is matched with the collected data according to the temperature attenuation step data, the ambient temperature is associated through time sorting, the temperature attenuation step data is associated with the detection data of the laser ranging unit, and the control unit controls the heating value of the lithium-ion battery through the associated data. The lithium-ion battery supplies energy to the temperature sensor, laser ranging unit and communication antenna in the monitoring equipment. The communication antenna interacts with the control unit, receives the control signal of the server, and updates the temperature attenuation step data in the control unit in real time. The control unit transmits the monitored temperature raw data and the matched associated data to the server through the communication antenna via the built-in DTU.

[0007] Differences from the existing technology: This online monitoring device for catenary compensation has the following obvious differences compared with the existing technology: Traditional catenary compensator monitoring equipment can usually only realize single function monitoring, such as temperature monitoring or distance monitoring. This new monitoring device integrates multiple functions such as temperature sensor, laser ranging unit, control unit and lithium-ion battery, and can realize multi-parameter monitoring and control of catenary compensator, thereby improving the comprehensiveness and accuracy of monitoring.

The equipment associates the ambient temperature through time sorting, and associates the temperature attenuation ladder data with the detection data of the laser ranging unit.

The laser ranging unit uses a high-precision laser sensor to realize the distance monitoring of the overhead line compensator; while the temperature sensor realizes the temperature change monitoring of the overhead line compensation equipment when it is working. The control unit receives the temperature change data and sorts and stores it according to time, obtains the temperature attenuation ladder data by measuring the distance and ambient temperature, and matches it with the collected data, thereby realizing multi-functional integrated monitoring.

Such real-time monitoring and remote management functions greatly improve the real-time and convenience of monitoring. Compared with the traditional manual inspection and regular maintenance methods, it can more timely discover and deal with abnormal conditions of the contact network compensator.

This data correlation and matching method can more accurately monitor the working status of the contact network compensator, improve the accuracy and reliability of the monitoring data, and is more intelligent and refined than traditional monitoring methods.

[0013] Compared with traditional monitoring equipment, this type of contact network compensation online monitoring equipment has obvious advantages such as multi-functional integration, real-time monitoring and remote management, data association and matching.
