Description

Technical Field

[0001] The present invention relates to the technical field of track monitoring, and in particular to an automatic monitoring system for the displacement state of a railway line track. Background Art

[0002] At present, the construction projects of frame bridges and culverts (pipes) passing under conventional railways require overhead line tracks and long-term slow-moving construction projects. There are two main methods for inspecting the status of railway tracks in construction areas: one is to use total station + prism to monitor the lateral and vertical displacements of the tracks, which has the problem of blind spots in observation. Especially when municipal engineering passes under the railway and the railway lines are overhead and jacked up, affected by the overhead facilities, the lateral and vertical displacements of the tracks cannot be directly observed using the total station. The deformation of the construction beams can only be observed, which is of little significance for guiding the line maintenance at the construction site. Another method is to use the gaps between trains to manually measure the geometric parameters of the track lines, and arrange personnel to repair the lines according to the problems found. In this method, inspectors frequently go on the track, which poses a risk to personal safety.

[0003] In summary, by designing and developing a system, real-time automatic monitoring of the static and dynamic geometric status of the track in the construction area can be achieved. Construction personnel can carry out planned and targeted repairs to the over-limited parts of the track based on the monitoring results to reduce the number of times personnel go on the track. This is an urgent need to ensure railway driving safety and reduce personal safety risks during construction on operating lines. Summary of the invention

After receiving the signal from the indoor host, the guidance maintenance group selects the location of the corresponding type A monitor and type B monitor according to the data, and thus performs maintenance on the track on the section at that location.

[0009] Preferably, the A-type monitor is installed between the rail bottoms of two rails to monitor and obtain the changes in the track gauge and horizontal height difference between the reference rail and the other rail;

[0010] Type B monitor is installed between the reference rail and the overhead system beam, and can monitor the horizontal displacement and height difference of the reference rail relative to the overhead system beam.

[0018] Preferably, the user management module can set corresponding permissions according to the different positions of the users, thereby facilitating the management of the system users and avoiding operational errors or malicious deletion of records;

[0019] The account management module can manage the logged-in account, including account password modification, permission setting and account cancellation.

[0020] Preferably, the alarm threshold module is used to obtain various monitoring indicators such as track gauge, level, triangular pit, height, track direction, etc., and set first-level warning and second-level warning alarms, so that the indoor host system makes corresponding alarm states according to the collected data.

[0021] Preferably, the system setting module includes an alarm module and a module for inputting the initial value of the system. When the input initial value exceeds the threshold set by the alarm module, the alarm module is activated and the indoor host system will display the specific situation of the alarm.

At this time, the indoor host system collects all the feedback data through the data acquisition module, and then analyzes the collected data through the alarm threshold module and the system setting module to obtain the corresponding data results. When the data result exceeds the threshold, the system setting module respectively issues a first-level alarm and a second-level alarm according to the percentage of the data exceeding the threshold, thereby reminding the staff to pay attention to the displacement problem of the track corresponding to the location of the type A monitor and the type B monitor. When there is no train passing, the indoor host system transmits the data of the section to the guidance maintenance team, so as to guide the maintenance team to perform corresponding maintenance work, thereby realizing real-time monitoring of the track. At the same time, manual measurement is no longer required, reducing the safety hazards of manual measurement.

[0036] The outdoor extension signal transmission is connected with type A monitor and type B monitor;

[0037] Among them, the A-type monitor is installed between the rail bottoms of two rails to monitor the changes in the track gauge and horizontal height difference between the reference rail and the other rail;

[0038] Among them, the B-type monitor is installed between the reference rail and the overhead system beam, which can monitor the horizontal displacement and height difference of the reference rail relative to the overhead system beam;

[0039] Type A monitor and Type B monitor are composed of displacement sensor, inclination sensor, acceleration sensor module, Chinese character LCD, STM32 embedded single chip computer and RS-485 communication interface, and are powered by connection adapter box and cables. The outdoor extension is electrically connected to Type A monitor and Type B monitor through network communication equipment in RS-485 communication mode to realize power supply and data transmission.

[0040] Among them, the maximum number of Type A monitors deployed on site is 64, and the address range is: 1-64;

[0041] Among them, the maximum number of Type B monitors deployed on site is 64, and the address range is: 65-128;

[0042] Among them, Type A monitors and Type B monitors are arranged in pairs with a spacing of 5m.

[0043] The indoor host system includes a data acquisition module, a historical curve module, a historical data module, a system setting module, an alarm threshold module, a benchmark setting module, a beam reset module, an initial value module, a user management module and an account management module;

[0044] The indoor host system also includes a guidance maintenance group. After receiving the signal from the indoor host, the guidance maintenance group selects the location of the corresponding Type A monitor and Type B monitor according to the data, and then performs maintenance on the track on the section at that location. This makes it convenient for the guidance maintenance group to accurately find the track section with problems, thereby improving maintenance efficiency and speed.

[0045] The data acquisition module collects monitor data and waveforms in real time, so the track status can be known in real time.

[0046] Furthermore, the collection objects include: track gauge, crossbeam, longitudinal beam (manual input), and acceleration sensor.

[0047] Among them, the historical curve module can perform historical queries on the data collected by the data acquisition module, and form a corresponding curve chart according to the changes in the data. The time end required for query can be input to query the historical data of the time period.

[0048] Among them, the historical data module can save all the data collected by the monitor, so it is convenient for operators to analyze the historical data, and then analyze in which time periods the track is prone to change, and make corresponding adjustments.

[0049] Among them, the user management module can set corresponding permissions according to the different positions of the users, thereby facilitating the overall management of all users of the system and avoiding bypassing operations or malicious deletion of records.

[0050] Among them, the account management module can manage the logged-in account, including account password modification, permission setting and account cancellation.

[0051] Among them, the alarm threshold module is used to obtain various monitoring indicators such as track gauge, level, triangular pit, height, track direction, etc., and set first-level warning and second-level warning alarms. Therefore, the indoor host system will make corresponding alarm states according to the collected data.

[0052] Among them, the system setting module includes an alarm module and a module for inputting the initial value of the system. When the input initial value exceeds the threshold set by the alarm module, the alarm module is activated, and the indoor host system will display the specific situation of the alarm. The system will give up to the latest 100 alarm data records. The character color of the records confirmed by the legal administrator of the system is displayed in black, and the character color of the unconfirmed records is displayed in red. After selecting the unconfirmed red record, click "Confirm", the record will become a confirmed record, the character display color will change from red to black, and the current record will automatically enter the next record to be confirmed. During the period when no trains are passing dynamically, the monitoring system monitors the static geometric size status of the line track in real time, and implements graded automatic sound alarms at 60% and 80% of the allowable deviation management value. Once the system graded alarm is generated, manual participation in confirmation management is required.

[0053] Among them, the benchmark setting module is for manually inputting relevant parameter settings for the longitudinal beams of the overhead system, including the track, longitudinal beam sensor position, horizontal benchmark and vertical benchmark. The actual set number of longitudinal beam sensors shall be based on the on-site configuration number, and the horizontal benchmark and vertical benchmark data of the unconfigured sensor parameters. The benchmark setting mainly considers the three-dimensional displacement changes of the overhead system itself. Monitoring points are set on the longitudinal beams of the overhead system (generally 3 points), and a manual input window is provided in the system program for the displacement value of the monitoring point. The displacement value will provide correction for the "track direction" and "height" deviations of the line track.

[0054] Among them, the beam reset module is a system that resets the B-type monitor installed between the reference rail and the overhead system beam.

[0055] Among them, the initial value module uses a standard track gauge to monitor the track gauge and superelevation of each A-type monitor as the original data of the indoor host system.

[0068] Working principle: When the system is started, the outdoor extension transmits the data collected by the type A monitor and the type B monitor to the indoor host system through the outdoor extension in real time. At this time, the indoor host system collects all the feedback data through the data acquisition module, and then analyzes the collected data through the alarm threshold module and the system setting module to obtain the corresponding data results. When the data result exceeds the threshold, the system setting module will respectively issue a first-level alarm and a second-level alarm according to the percentage of the data exceeding the threshold, thereby reminding the staff to pay attention to the displacement problem of the track corresponding to the location of the type A monitor and the type B monitor. When there is no train passing, the indoor host system transmits the data of the section to the guidance maintenance team, so as to guide the maintenance team to do the corresponding maintenance work;
