Description

Technical Field

[0001] The invention relates to the technical field of railway engineering, and in particular to an automated deformation monitoring method and device for railway equipment and facilities. Background Art

[0002] When construction activities are carried out around existing railway lines or when railway lines pass through geologically active areas, the risk of track settlement and displacement increases significantly. If the deformation of the rails exceeds the safety standard, the safety of train operation will be threatened. In order to maintain the safe operation of the railway and ensure the normal progress of construction, the deformation of railway facilities must be monitored. At present, the methods for monitoring the deformation of railway equipment mainly include the following: 1. Static leveling method: This method does not interfere with the normal operation of the railway, but it can only measure settlement and cannot measure horizontal displacement. In addition, the monitoring equipment is easily affected by the surrounding environment, the monitoring element is large in size, and it cannot directly measure the deformation of light sleepers. 2. Traditional leveling: This method has high measurement accuracy, but the measurement process is time-consuming and the frequency is limited. It can only measure settlement and cannot monitor horizontal displacement. 3. Burying settlement piers or displacement monitoring markers in the roadbed: The burial process of this method is complicated and the error of the measurement result is large.

[0003] Taking all factors into consideration, these three commonly used monitoring methods each have their own advantages and disadvantages. Their measurement errors are relatively large, and none of them can realize the automatic monitoring of the deformation of railway equipment and facilities without affecting the normal operation of the railway. Therefore, it is urgent to design a method and device that can realize the automatic deformation monitoring of railway equipment and facilities. Summary of the invention

[0004] The purpose of the present invention is to overcome the deficiencies of the prior art and to provide a method for automatically monitoring the deformation of railway equipment and facilities, so as to realize automatic monitoring of the deformation of railway equipment and facilities without affecting the normal operation of the railway.

[0005] In order to achieve the above purpose, an automatic deformation monitoring method for railway equipment and facilities is designed, and the method is as follows: S1. A detection system is set in the measuring robot, and the detection system includes a CCD camera, and the CCD camera integrates an infrared transmitting and receiving device, and the detection system is directed to the accurate position of the center of the prism in the railway equipment and facilities, and the measuring robot is driven to move by the power drive system; S2. The measuring robot realizes automatic aiming during movement, and the automatic aiming method is as follows: the infrared transmitting and receiving device in the measuring robot emits an infrared laser, and the laser beam is reflected by the prism and received by the infrared receiving device to form an aiming spot; the deviation between the aiming spot and the target prism is calculated, and the motor driving detection system is adjusted to calibrate the horizontal angle and vertical angle parameters, so as to clarify the accurate value of the center of the spot and realize automatic aiming of the target; S3. The measuring robot identifies the monitoring point fixed on the track bed through the CCD camera, and the monitoring point directly reflects the settlement change of the track, and transmits the measured and recorded data to the data acquisition terminal through the wireless network; S4. The data acquisition terminal summarizes and processes the received data, and uses statistical test methods to determine gross errors, multi-measurement weight integration calculation and breakpoint processing technology to perform automated data analysis; S5. The processed data is transmitted to the database server via a wireless network, and the data in the database server is monitored in real time by an automated monitoring system; S6. By comparing the monitoring data at different time points, the settlement of the track or roadbed is calculated, and the height difference at different time points is analyzed using a differential data-based method to determine the settlement situation; S7. Calculate the change data of the time series to evaluate the settlement rate, and when the monitoring results exceed the safety regulations, send real-time alarm information to the user through the automatic alarm system to ensure the safe operation of railway equipment and facilities.

[0006] The present invention also provides an automated deformation monitoring device for railway equipment and facilities using the above method, comprising: a power drive system for driving a measuring robot to move; a detection system, which is arranged in the measuring robot, the detection system comprising a CCD camera and an integrated infrared transmitting and receiving device, the CCD camera is used to obtain images of the track and its surrounding environment, and the infrared transmitting and receiving device is used to achieve automatic aiming; a data acquisition terminal, which is wirelessly connected to the measuring robot and is used to receive, summarize and process data transmitted by the CCD camera and the infrared device, and perform real-time monitoring; a database server, which is connected to the data acquisition terminal and is used to store and analyze data and provide the processed data to the automated monitoring system; an automatic alarm system, which can send an alarm message to the user when the monitoring data exceeds the safety regulations.

[0007] Compared with the prior art, the present invention has the following advantages: Through the independently innovated automated deformation monitoring method for railway equipment and facilities, the deformation of existing structures can be monitored at any time throughout the construction process, and feedback can be given to the owner, supervisor, and equipment management unit so that timely measures can be taken to ensure that construction work on adjacent operating lines is within a safe and controllable range, and that the on-site monitoring and feedback process is reasonable and efficient.

The database server 10 is used to save the processed data in the data module 2, the automatic monitoring system 11 is used to monitor the data in the database server 10, and the automatic alarm system 12 is used to issue a real-time alarm for data that does not meet the specifications in the automatic monitoring system 11.

[0013] The automatic measurement system 7 includes servo motor driving software. When the same operation needs to be performed, only an instruction needs to be issued, and the servo motor driving software will be started, so that the measuring robot automatically completes a series of measurements. The automatic measurement system 7 uses the total station corner intersection method for measurement. The automatic data processing system 9 includes a statistical test method for determining gross errors, multi-measurement weight integration calculation and breakpoint processing technology for data processing.

[0014] Embodiment 2: See also Figure 2 This embodiment provides a method for automated deformation monitoring of railway equipment and facilities, comprising the following steps: A. When measuring, the target is roughly aimed at for the first time and instructions are issued to the measuring robot through the target recognition software 6. The CCD camera 5 in the measuring robot can automatically perform logic analysis on the returned signal with the help of the target recognition software 6, accurately determine the position of the prism center, and then automatically measure, record, and transmit data.

[0015] B. The measured and recorded data are transmitted to the data acquisition terminal 8 via a wireless network.

[0016] C. The data collection terminal 8 aggregates the data and performs automated data processing 9 through various methods.

[0017] D. The automatically processed data is transmitted to the database server 10 via a wireless network.

[0018] E. The data in the database server 10 is monitored in real time by the automatic monitoring system 11.

[0019] F. The automatic alarm system 12 sends an alarm message to the user when the data exceeds the safety regulations during monitoring.

[0020] The railway equipment and facility automated deformation monitoring method adopts a railway equipment and facility automated deformation monitoring system, which includes a field data acquisition module 1, a data processing module 2 and a monitoring information management module 3.

[0021] In the step A, the measuring robot includes a servo motor driving software. When the same operation needs to be performed, only an instruction needs to be issued, and the servo motor driving software will be started, so that the measuring robot automatically completes a series of measurements. In the step A, automatic measurement refers to measurement by the total station corner intersection method.

[0022] It is worth noting that the measuring robot first performs the process of aiming at the target with the prism, and the part irradiated by the laser is not necessarily the center of the prism. The CCD camera 5 receives the aiming light spot reflected by the prism. If the light spot deviates from the center of the prism, the CCD camera 5 calculates the offset and drives the telescope to move directly to the center of the prism.

Any technician familiar with the technical field can make equivalent substitutions or changes according to the technical solutions and novel concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
