Description

Technical Field

[0001] The invention relates to the technical field of track engineering diagnosis, in particular to a track diagnosis electrical control system applied to ultrasonic detection of railway rails. Background Art

[0002] With the continuous growth of my country's railway mileage, the continuous acceleration of railway transportation speed, and the increasingly developed urban rail transit, the requirements for engineering machinery and equipment to ensure the safety of railways and urban rail transit are also getting higher and higher. At present, railway track monitoring equipment based on ultrasonic transmission has been widely used in railway engineering systems and urban rail transit fields. Track monitoring equipment based on ultrasonic transmission must use coupling fluid as a medium so that ultrasonic waves can smoothly enter the track and realize ultrasonic transmission. Therefore, it is necessary to design a coupling fluid control method that can be intelligently controlled.

[0003] The electrical control system for flaw detection usually contains multiple subsystems with relatively independent functions. The relatively independent subsystems work together to provide a good monitoring environment and conditions for the stable, high-quality and efficient rail flaw detection work of rail ultrasonic flaw detection monitoring. However, when the existing rail flaw detection vehicle is in operation, the multiple electrical subsystems require the operator to perform real-time control and adjustment according to the actual operating conditions. At the same time, the entire electrical system is an open-loop system, lacking real-time feedback and not intelligent. Therefore, the existing rail flaw detection electrical control system has the following technical defects:

[0004] 1) During the rail flaw detection operation, due to the presence of fine impurities in the liquid in the liquid tank and the long storage time of the liquid in the pipeline, although the liquid is filtered by the filter, there will still be some fine impurities blocking the spray device. The operator will only find the blockage state of the spray device by observing the monitoring camera screen if he sees the long-distance lost bottom wave on the monitoring software interface B-type diagram (a display method of ultrasonic flaw detection cross-sectional diagram, which can display the longitudinal cross-sectional image of the inspected rail and indicate the approximate size and relative position of the ultrasonic reflector in the rail, the horizontal axis indicates the mileage position of the damage, and the vertical axis indicates the depth of the damage under the rail surface). This will result in the failure to detect the blockage of the spray device in time, and there will be a situation where the monitoring data is invalid for a considerable distance.

[0005] 2) During the rail flaw detection operation, the operation of the ultrasonic operating device is open-loop controlled, and it is necessary to monitor the display or get off the vehicle to observe and confirm its operation with the naked eye. However, these processes cannot completely ensure that there is a possibility of air leakage in certain air circuits, resulting in the ultrasonic operating device being unable to reach the normal state actually required.

[0006] 3) During the rail flaw detection operation, due to rainy and snowy weather and long-term operation in a humid environment, there will be ice or mud in the ultrasonic operating mechanism, which will affect the downward pressure of the ultrasonic operating device. Once this phenomenon occurs, the monitoring data will be invalid within a considerable distance. Summary of the invention

[0007] In view of this, the purpose of the present invention is to provide a track diagnostic electrical control system to solve the technical problems that multiple subsystems of the existing track diagnostic electrical control system require operators to perform real-time control and adjustment according to actual operating conditions, the entire electrical system is open-loop, lacks real-time feedback, and does not have intelligent characteristics.

[0008] In order to achieve the above-mentioned invention object, the present invention specifically provides a technical implementation scheme of a track diagnosis electrical control system, the track diagnosis electrical control system comprising:

[0009] A liquid tank, a flow monitoring unit and a spraying unit connected in sequence, wherein the liquid in the liquid tank passes through the flow monitoring unit and the spraying unit and is then sprayed to the target;

[0010] An air source, a pressure monitoring unit and an ultrasonic operation device are connected in sequence, wherein the air source controls the lifting and lowering of the ultrasonic operation device after passing through the pressure monitoring unit;

[0011] A main controller, and an alarm device and a travel monitoring unit connected to the main controller. The travel monitoring unit monitors the travel of the ultrasonic operation device and feeds back the travel information to the main controller.

[0012] The main controller is connected to a flow monitoring unit, and the flow monitoring unit feeds back flow information to the main controller. The main controller is connected to a pressure monitoring unit, and the pressure monitoring unit feeds back pressure information to the main controller.

[0013] The main controller receives feedback information from the flow monitoring unit, the pressure monitoring unit and the stroke monitoring unit, and determines whether to send an alarm message to the alarm device after making a judgment.

[0014] Furthermore, the control system also includes a power source connected between the liquid tank and the flow monitoring unit, and the power source is connected to the main controller and controlled by the main controller.

[0015] Furthermore, the liquid tank, power source, flow monitoring unit and spraying unit are connected in sequence through a liquid pipeline. The main controller can open or close the power source at any time, open or close the liquid pipeline, and monitor the flow in the liquid pipeline.

[0016] Furthermore, the flow monitoring unit can monitor at any time whether the liquid flow in the liquid pipeline is consistent with the set flow. If it is inconsistent, the main controller sends an audible and visual alarm and prompt information to the alarm device to remind the operator to deal with the spray unit in time and restore the liquid flow to the set value.

[0017] Furthermore, after the control system is powered on, the main controller first determines whether the power source is turned on. If not, it repeatedly monitors the power source on status. If the power source is turned on, the flow monitoring unit collects the flow information of the liquid, and then feeds the flow information back to the main controller. After receiving the flow information feedback value, the main controller compares it with the initial setting value. If it is consistent with the initial setting value, the sound and light alarm and prompt information of the alarm device are cleared. If the flow information feedback value is inconsistent with the initial setting value, the main controller sends an alarm message to the alarm device. After receiving the alarm message, the alarm device immediately sends an sound and light alarm and prompt information to remind the operator to handle it, restore the spray unit to a normal spraying state, and check whether the power source is turned on. The above actions are repeatedly performed until the control system loses power.

[0018] Furthermore, the gas source, pressure monitoring unit and ultrasonic operation device are connected in sequence through an air circuit, and the main controller can control the opening or closing of the gas source, monitor the pressure of the air circuit, and control the operation of the ultrasonic operation device.

[0019] Furthermore, the pressure monitoring unit collects pressure signals of the gas in the gas path and feeds back the collected pressure information to the main controller. The main controller determines whether to send an alarm message to the alarm device according to the feedback pressure information to remind the operator to handle and restore the normal operation of the ultrasonic operation device.

[0020] Furthermore, after the control system is powered on, the main controller first determines whether the gas source is turned on. If not, it repeatedly monitors whether the gas source is turned on. If the gas source is turned on, the pressure monitoring unit collects gas pressure information and then feeds back the pressure information to the main controller. After receiving the pressure information feedback value, the main controller compares it with the initial setting value. If it is consistent with the initial setting value, it indicates that the operation of the ultrasonic operation device is normal. The main controller clears the alarm information and returns to query whether the gas source is turned on. If the pressure information feedback value is inconsistent with the initial setting value, it indicates that the operation of the ultrasonic operation device is abnormal. The main controller sends an audible and visual alarm and prompt information to the alarm device to remind the operator to handle it, restore the ultrasonic operation device to a normal operation state, and then check whether the gas source is turned on. The above actions are repeated until the control system loses power.

[0021] Furthermore, the travel monitoring unit collects the travel signal of the ultrasonic operation device and feeds back the collected travel information to the main controller. The main controller determines whether to send an alarm message to the alarm device according to the fed-back travel information to remind the operator to process and restore the normal travel of the ultrasonic operation device.

[0022] Furthermore, after the control system is powered on, the main controller first determines whether the action instruction of the ultrasonic operation device has been issued. If not, it repeatedly monitors whether the action instruction of the ultrasonic operation device has been issued. If the action instruction has been issued, the stroke monitoring unit collects the action stroke information of the ultrasonic operation device. After receiving the stroke information feedback value, the main controller compares it with the initial setting value. If it is consistent with the initial setting value, it indicates that the action stroke of the ultrasonic operation device is normal. The main controller clears the alarm information and returns to query whether the action instruction of the ultrasonic operation device has been sent. If the stroke information feedback value is inconsistent with the initial setting value, it indicates that the action stroke of the ultrasonic operation device is abnormal. The main controller sends an audible and visual alarm and prompt information to the alarm device to remind the operator to handle it, restore the ultrasonic operation device to the normal stroke state, and then query whether the action instruction of the ultrasonic operation device has been sent. The above actions are repeatedly performed until the control system loses power.

[0023] By implementing the technical solution of the track diagnosis electrical control system provided by the present invention, the following beneficial effects are achieved:

[0024] (1) The rail diagnostic electrical control system of the present invention forms a closed loop as a whole, and real-time feedback of flow, pressure and stroke are achieved. It has a highly intelligent feature, which solves the technical defect that multiple subsystems of the existing control system require operators to perform real-time control and adjustment according to actual operating conditions, and greatly reduces the complexity of system operation;

[0025] (2) The rail diagnostic electrical control system of the present invention has a flow monitoring function. Instead of observing the spraying unit status through the monitoring screen, the flow monitoring function is changed to flow monitoring, which is not affected by the external environment (ice and snow, night, fog, etc.). The operator can grasp the actual situation of the spraying unit anytime and anywhere, which reduces the work intensity and improves the convenience and safety of system operation.

[0026] (3) The rail diagnostic electrical control system of the present invention has a pressure monitoring function. The pressure monitoring unit enables the operator to clearly understand the actual operation status of the ultrasonic operation unit at any time, further reducing the workload and improving the convenience and safety of system operation.

[0027] (4) The rail diagnostic electrical control system of the present invention has a travel monitoring function. The travel monitoring unit allows the operator to understand the actual travel status of the ultrasonic operation unit in advance, further reducing the workload and improving the convenience and safety of system operation.

[0042] As attached Figure 1 To Attachment Figure 7 As shown, a specific embodiment of the track diagnosis electrical control system of the present invention is given, and the present invention is further described below in conjunction with the drawings and specific embodiments.

[0043] As attached Figure 7 As shown, an embodiment of a track diagnostic electrical control system of the present invention, the system specifically comprises:

[0044] The liquid tank 3, the flow monitoring unit 2 and the spraying unit 5 are connected in sequence, and the liquid in the liquid tank 3 is sprayed to the target after passing through the flow monitoring unit 2 and the spraying unit 5;

[0045] An air source 7, a pressure monitoring unit 6 and an ultrasonic working device 8 are connected in sequence, and the air source 7 controls the lifting and lowering of the ultrasonic working device 8 after passing through the pressure monitoring unit 6;

[0046] A main controller 1 , and an alarm device 4 and a travel monitoring unit 9 connected to the main controller 1 . The travel monitoring unit 9 monitors the travel of the ultrasonic operation device 8 and feeds back the travel information to the main controller 1 .

[0047] The main controller 1 is connected to the flow monitoring unit 2, and the flow monitoring unit 2 feeds back the flow information to the main controller 1. The main controller 1 is connected to the pressure monitoring unit 6, and the pressure monitoring unit 6 feeds back the pressure information to the main controller 1.

[0048] The main controller 1 receives feedback information from the flow monitoring unit 2 , the pressure monitoring unit 6 and the stroke monitoring unit 9 , and determines whether to send (sound and light) alarm information to the alarm device 4 after making a judgment.

[0049] As a preferred specific embodiment of the present invention, the track diagnostic electrical control system further includes a power source 10 connected between the liquid tank 3 and the flow monitoring unit 2, and the power source 10 is connected to the main controller 1 and controlled by the main controller 1. The liquid in the liquid tank 3 passes through the power source 10 (or does not include the power source 10, only the pipeline), the flow monitoring unit 2, and the spraying unit 5, and is sprayed to the target, wherein the power source 10 is controlled by the main controller 1, and the flow monitoring unit 2 feeds back the flow information to the main controller 1. The liquid tank 3, the power source 10, the flow monitoring unit 2 and the spraying unit 5 are connected in sequence through the liquid pipeline. The main controller 1 can open or close the power source 10 at any time, open or close the liquid pipeline, and monitor the flow size in the liquid pipeline.

[0050] As attached Figure 1 , which is a block diagram of the connection structure of the relevant modules for realizing the flow monitoring function in the rail diagnostic electrical control system described in a specific embodiment of the present invention. The flow monitoring unit 2 can monitor at any time whether the liquid flow in the liquid pipeline is consistent with the set flow. If it is inconsistent, the main controller 1 sends an audible and visual alarm and prompt information to the alarm device 4 to remind the operator to deal with the spray unit 5 in time and restore the liquid flow to the set value.

[0051] As attached Figure 2As shown, it is a program flow chart of the flow monitoring process of the track diagnosis electrical control system described in a specific embodiment of the present invention. After the track diagnosis electrical control system is powered on, the main controller 1 first determines whether the power source 10 is turned on. If not, it repeatedly monitors the power source 10. If the power source 10 is turned on, the flow monitoring unit 2 collects the flow information of the liquid, and then feeds the flow information back to the main controller 1. After receiving the flow information feedback value, the main controller 1 compares it with the initial setting value. If it is consistent with the initial setting value, the sound and light alarm and prompt information of the alarm device 4 are cleared. If the flow information feedback value is inconsistent with the initial setting value, the main controller 1 sends an alarm message to the alarm device 4. After receiving the alarm message, the alarm device 4 immediately sends an sound and light alarm and prompt information to remind the operator to handle it, restore the spray unit 5 to the normal spraying state, and check whether the power source 10 is turned on. The above actions are repeatedly performed until the track diagnosis electrical control system loses power.

[0052] As attached Figure 3 As shown, it is a block diagram of the connection structure of the relevant modules for realizing the pressure monitoring function in the rail diagnostic electrical control system described in the specific embodiment of the present invention. The gas source 7, the pressure monitoring unit 6 and the ultrasonic working device 8 are connected in sequence through the gas circuit, and the main controller 1 can control the opening or closing of the gas source 7, monitor the pressure of the gas circuit, and control the operation of the ultrasonic working device 8. After the gas source 7 passes through the pressure monitoring unit 6, it controls the lifting device of the ultrasonic working device 8, wherein the pressure monitoring unit 6 feeds back the pressure information to the main controller 1. The pressure monitoring unit 6 collects the pressure signal of the gas in the gas circuit and feeds back the collected pressure information to the main controller 1. The main controller 1 determines whether to send an alarm message to the alarm device 4 based on the feedback pressure information, and reminds the operator to handle and restore the normal operation of the ultrasonic working device 8.

[0053] As attached Figure 4 As shown, it is a program flow chart of the pressure monitoring process of the track diagnosis electrical control system described in a specific embodiment of the present invention. After the track diagnosis electrical control system is powered on, the main controller 1 first determines whether the gas source 7 is turned on. If not, it repeatedly monitors whether the gas source 7 is turned on. If the gas source 7 is turned on, the pressure monitoring unit 6 collects gas pressure information and then feeds the pressure information back to the main controller 1. After receiving the pressure information feedback value, the main controller 1 compares it with the initial setting value. If it is consistent with the initial setting value, it indicates that the operation of the ultrasonic operation device 8 is normal. The main controller 1 clears the alarm information and returns to query whether the gas source 7 is turned on. If the pressure information feedback value is inconsistent with the initial setting value, it indicates that the operation of the ultrasonic operation device 8 is abnormal. The main controller 1 sends the sound and light alarm and prompt information to the alarm device 4 to remind the operator to handle it, restore the ultrasonic operation device 8 to the normal operation state, and then check whether the gas source 7 is turned on. The above actions are repeatedly performed until the track diagnosis electrical control system loses power.

[0054] As attached Figure 5 As shown, it is a block diagram of the connection structure of the relevant modules for realizing the travel monitoring function in the rail diagnostic electrical control system described in a specific embodiment of the present invention. The travel monitoring unit 9 collects the travel signal of the ultrasonic working device 8, and feeds back the collected travel information to the main controller 1. As soon as the travel monitoring unit 9 is powered on, it monitors the lifting device travel of the ultrasonic working device 8, and feeds back the travel information to the main controller 1. The main controller 1 determines whether to send an alarm message to the alarm device 4 based on the feedback travel information, and reminds the operator to handle and restore the normal travel of the ultrasonic working device 8.

[0055] As attached Figure 6 As shown, it is a program flow chart of the travel monitoring process of the track diagnosis electrical control system described in a specific embodiment of the present invention. After the track diagnosis electrical control system is powered on, the main controller 1 first determines whether the action instruction of the ultrasonic operation device 8 has been issued. If not, it repeatedly monitors whether the action instruction of the ultrasonic operation device 8 has been issued. If the action instruction has been issued, the travel monitoring unit 9 collects the action travel information of the ultrasonic operation device 8. After receiving the travel information feedback value, the main controller 1 compares it with the initial setting value. If it is consistent with the initial setting value, it indicates that the action travel of the ultrasonic operation device 8 is normal. The main controller 1 clears the alarm information and returns to query whether the action instruction of the ultrasonic operation device 8 has been sent. If the travel information feedback value is inconsistent with the initial setting value, it indicates that the action travel of the ultrasonic operation device 8 is abnormal. The main controller 1 sends an audible and visual alarm and prompt information to the alarm device 4 to remind the operator to handle it, restore the ultrasonic operation device 8 to the normal travel state, and then query whether the action instruction of the ultrasonic operation device 8 has been sent. The above actions are repeatedly performed until the track diagnosis electrical control system loses power.

[0056] In order to solve the technical problems of timely discovering that the spray unit 5 is blocked, the air circuit is leaking, and the ultrasonic operation device 8 is not in place, the rail diagnostic electrical control system described in the specific embodiment of the present invention includes three monitoring units. A flow monitoring unit 2 is used on the conveying pipeline to monitor the flow change of the liquid through the flow monitoring unit 2, and timely discover that the spray device 5 is blocked and remind the operator to deal with it; a monitoring means of a pressure monitoring unit 6 is added to the air pipeline, and the pressure change of the air circuit is monitored through the pressure monitoring unit 6, and the leakage phenomenon is timely discovered and handled; a stroke monitoring unit 9 is added to the ultrasonic operation device 8, and the stroke monitoring unit 9 is used to monitor whether the descending position of the lifting device of the ultrasonic operation device 8 reaches the expected effect, so as to timely discover whether the ultrasonic operation device 8 is covered by ice slag or mud, and clear it. Through the above means, the track operating personnel can be reminded to deal with it in time, so as to achieve the purpose of maximizing the safety and monitoring effect of the rail diagnostic electrical control system.

The rail diagnostic electrical control system according to claim 1, 2, 3, 4, 5, 7 or 8, characterized in that: The travel monitoring unit (9) collects the travel signal of the ultrasonic operation device (8) and feeds back the collected travel information to the main controller (1); the main controller (1) determines whether to send an alarm message to the alarm device (4) based on the fed-back travel information, and reminds the operator to process and restore the normal travel of the ultrasonic operation device (8).

10. The rail diagnostic electrical control system according to claim 9, characterized in that: After the control system is powered on, the main controller (1) first determines whether the action instruction of the ultrasonic operation device (8) has been issued. If not, it repeatedly monitors whether the action instruction of the ultrasonic operation device (8) has been issued. If the action instruction has been issued, the stroke monitoring unit (9) collects the action stroke information of the ultrasonic operation device (8). After receiving the stroke information feedback value, the main controller (1) compares it with the initial setting value. If it is consistent with the initial setting value, it indicates that the action stroke of the ultrasonic operation device (8) is normal. The main controller (1) clears the alarm information and then returns to query whether the action instruction of the ultrasonic operation device (8) has been sent. If the stroke information feedback value is inconsistent with the initial setting value, it indicates that the action stroke of the ultrasonic operation device (8) is abnormal. The main controller (1) sends an audible and visual alarm and prompt information to the alarm device (4) to remind the operator to handle it and restore the ultrasonic operation device (8) to a normal stroke state, and then queries whether the action instruction of the ultrasonic operation device (8) has been sent. The above actions are repeatedly performed until the control system loses power.
