Description

Technical Field

[0001] This utility model relates to the field of monitoring technology for internal support parking anti-roll devices, and in particular to a three-in-one intelligent monitoring system for internal support parking anti-roll devices. Background Technology

[0002] Internal support anti-runaway devices are typically installed on railway station lines, depot lines, branch lines, marshalling yards, and special purpose lines. Their main purpose is to prevent trains from running away while stationary.

[0003] However, the currently used internal support type parking anti-roll device has some drawbacks:

[0004] When its internal transmission structure malfunctions, operators need to manually brake or release the brakes on-site. This increases safety risks due to the delayed discovery of the problem and the need for on-site operation.

[0005] To address this, a three-in-one intelligent monitoring system for internal support parking anti-rollover devices is proposed. Utility Model Content

[0006] In order to solve the problems existing in the prior art, this utility model provides a three-in-one intelligent monitoring system for an internal support type parking anti-roll device, which solves the technical problems mentioned in the background section above.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] The three-in-one intelligent monitoring system for the internal support type parking anti-roll device proposed in this utility model includes a control cabinet, a control terminal, a display screen, and a monitoring system.

[0009] The monitoring system includes a position switch monitoring system, a pressure sensor monitoring system, and a video transmission monitoring system. Through the combined monitoring of these systems, real-time monitoring of the equipment's working status is achieved. The position switch monitoring system, pressure sensor monitoring system, and video transmission monitoring system transmit signals to the control terminal, which then performs corresponding operations.

[0010] Preferably, the positioning switch monitoring system includes a positioning switch, which is placed inside the internal support type anti-rollover device. When the internal support type anti-rollover device is braking or releasing, the positioning switch changes its state in real time and transmits the state to the control cabinet. Then, the conversion module of the control cabinet converts the state information into an optical fiber signal and transmits it to the remote control terminal to indicate the current working state of the parking device—braking or releasing, thereby achieving the purpose of monitoring the working state.

[0011] Preferably, the pressure sensing and monitoring system includes a pressure sensor embedded inside the spring box of the internal support type anti-rollover device. During the spring change process of the internal support type anti-rollover device, the pressure data is measured and a piezoelectric signal is generated. This signal is converted into a digital signal by a transmitter and transmitted to the local control cabinet. The signal is then converted into an optical fiber signal by a switch and transmitted to the remote control terminal. The system monitors the quality of the braking or release of the parking device and whether the train moves during the parking process in real time by monitoring the changes in the pressure value.

[0012] Preferably, the video transmission monitoring system includes a monitoring camera that captures real-time video of the brake rail's operating status. The video data obtained through control software is transmitted to the control cabinet, and then converted into fiber optic signals via a switch for synchronous transmission to the control terminal. The remote monitoring terminal can monitor the real-time operating status of the on-site parking device.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the "three-in-one intelligent monitoring" system of the internal support parking anti-roll device in this utility model effectively solves this drawback. Through real-time monitoring and automatic remote operation, it reduces the intensity of manual work, lowers the risk of operation, and improves the efficiency of parking anti-roll operation.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] This utility model provides a three-in-one intelligent monitoring system for an internal support type parking anti-roll device, including a control cabinet, a control terminal, a display screen, and a monitoring system. The monitoring system includes a position switch monitoring system, a pressure sensor monitoring system, and a video transmission monitoring system. Through the combined monitoring of the position switch monitoring system, the pressure sensor monitoring system, and the video transmission monitoring system, real-time monitoring of the device's working status is realized. The position switch monitoring system, the pressure sensor monitoring system, and the video transmission monitoring system transmit signals to the control terminal, which then performs corresponding operations.

[0019] Specifically as follows:

[0020] like Figure 1 As shown, the positioning switch monitoring system includes a positioning switch, which is placed inside the internal support type anti-rollover device. During the braking and releasing states of the internal support type anti-rollover device, the positioning switch changes its state in real time and transmits the state to the control cabinet. Then, the control cabinet's conversion module converts the state information into an optical fiber signal and transmits it to the remote control terminal, indicating the current working state of the parking device—braking or releasing—thereby achieving the purpose of monitoring the working state.

[0021] like Figure 2 As shown, the pressure sensing and monitoring system includes a pressure sensor embedded inside the spring box of the internal support type anti-runaway brake. During the spring changes of the internal support type anti-runaway brake, the system measures the pressure data and generates a piezoelectric signal. This signal is converted into a digital signal by a transmitter and transmitted to the local control cabinet. The signal is then converted into a fiber optic signal by a switch and transmitted to the remote control terminal. By monitoring changes in pressure values ​​in real time, the system assesses the quality of the brake's braking or release and whether the train has moved during its stop. This allows for early intervention and control of runaway events, effectively preventing serious incidents.

[0022] like Figure 2 As shown, the video transmission monitoring system includes monitoring cameras installed on the internal support type anti-rollover parking device. These cameras are positioned 1 meter from the centerline of the non-motor end of the parking device. The cameras capture real-time video of the brake rail's operating status. The video data obtained through control software is transmitted to the control cabinet, and then converted into fiber optic signals via a switch for synchronous transmission to the control terminal. At the remote monitoring terminal, the stability of the parking device's operation and the occurrence of any abnormalities can be monitored in real time. When an abnormality is detected, an alarm is immediately triggered, and on-duty personnel can perform corrective actions. By controlling and intervening in the early stages of rollover incidents, serious accidents are effectively prevented.

[0023] Working principle of the "three-in-one" intelligent monitoring system for internal support parking anti-roll device

[0024] This monitoring system has two main functions: detection and alarm. It provides a reliable real-time monitoring method, instantly determining whether the internal support anti-rollover parking device is effectively braking and releasing by comparing pressure measurements and images. Simultaneously, it notifies staff of any potential risks via voice and visual alarms, facilitating quick and accurate problem identification and troubleshooting by staff. This further improves the reliability of the internal support anti-rollover parking device and significantly reduces the risk of vehicle slippage or obstruction due to transmission failures or other factors.

[0025] In practice, such as Figure 3 As shown, the internal support anti-runaway parking device adopts a "2+2" parking device installation scheme. Its advantage is that it can meet the parking needs of trains of different lengths. The control cabinet includes control cabinet A and control cabinet B. Control cabinet A independently controls devices 1-2; control cabinet B independently controls devices 3-4. However, the data from control cabinets A and B can be transmitted to the control terminal simultaneously and in real time and presented in the form of images.

[0026] This system provides a monitoring system for an internally supported anti-rollover parking device, including pressure sensors and signal transmitters, as well as auxiliary real-time monitoring cameras, a signal control cabinet installed near the track line, and monitoring software installed in the control cabinet and control terminal. Information transmitted by the signal transmitters is converted to network transmission via a signal converter and simultaneously connected to a network switch along with monitoring data, then transmitted via fiber optic cable to the control cabinet and signal tower. Each parking device is equipped with six spring boxes, each containing a coaxial pressure sensor. The spring boxes are mounted on a brake base beam perpendicular to the brake rail. Additionally, each parking device is equipped with a high-definition monitoring camera mounted in front of it, parallel to the central axis of the brake arm, one meter away from the outermost brake base beam.

[0027] The normal operating procedure of the internal support type anti-rollover device is as follows: After the train comes to a complete stop on the track, the braking operation is initiated. The motor drives the brake arm to rise and extend to both sides, clamping the train's wheel flanges until the brakes are fully engaged, a braking completion signal is sent, and the motor stops rotating. When the train needs to move, the release operation is initiated. The motor drives the brake arm to retract inward and lower back to its initial position, a release completion signal is sent, and the motor stops rotating. When the brake transmission mechanism malfunctions, the above process may present the following risks:

[0028] (1) The brake cannot be engaged within the specified time;

[0029] (2) After the braking signal is generated, the brake arm does not clamp the wheel flange or the braking force generated is insufficient;

[0030] (3) The symptoms cannot be relieved within the specified time;

[0031] (4) After the release signal is generated, the brake arm does not disengage from the wheel flange or does not completely disengage.

[0032] To address the aforementioned issues, this monitoring system employs the following measures:

[0033] (1) The monitoring software acquires the action signals sent by the parking anti-rollover control system in real time. When the start braking or start release action signal is acquired, the action time is calculated. According to TB / T 3162.1-2007, the braking time or release time must not exceed 30s. If the control system fails to send the braking or release signal within the specified time, the monitoring software will issue an interface and voice alarm to indicate that the action timeout has occurred.

[0034] (2) Based on the actual working conditions, we need to preset the increment threshold that the pressure should obtain when braking is normal. The monitoring software acquires the pressure value measured by the pressure sensor in real time. When the monitoring software receives the start braking signal sent by the control system of the parking anti-rollover device, the monitoring software will use the pressure value measured before the start action as the comparison baseline value and save the current working condition photo 1. When normal braking is in place, the pressure value increment closest to the wheel position is the largest, and the pressure value increment far from the wheel position is smaller, or even decreases instead of increasing. Through this phenomenon, we can more accurately determine the wheel's pressure position. If the maximum increment is less than the increment threshold that should be obtained under normal braking, we can reasonably suspect that the braking force is insufficient, and thus issue a warning;

[0035] (1) After braking to the position, the monitoring software will automatically take and save a frame of working condition photo 2. If the sensor increment near the initial pressure position decreases significantly during the parking period, while the sensor increment far from the initial pressure position increases significantly, the working condition photo 2 saved when braking to the position is completed will be compared with the current real-time monitoring screen to calculate the structural similarity index. When the index indicates that the image has changed significantly, we can reasonably assume that the vehicle has undergone abnormal displacement and issue a warning.

[0036] (2) When the monitoring software receives the relief signal sent by the control system of the parking anti-rollover device in real time, if the relief is normal, the difference between each pressure measurement value and the initial baseline value will not exceed the reasonable range. If it exceeds the reasonable range, the stored working condition photo 1 will be retrieved and compared with the current real-time monitoring screen to calculate the structural similarity index. When the index indicates that the image has changed significantly, we can reasonably assume that the brake arm relief is abnormal and issue an early warning.

[0037] (3) When the above warning occurs, staff can access the real-time monitoring screen of the abnormal parking device through the monitoring software of the control cabinet or signal tower for observation.

[0038] (4) The above warnings remind staff to promptly check and repair the equipment's operating condition.

[0039] The technological advantages and long-term benefits of the "three-in-one" intelligent monitoring system for internal support parking anti-rollover devices.

[0040] This system integrates real-time video monitoring and pressure sensing technology to achieve digital and visual management, providing staff with accurate and reliable information on the operating status of parking devices and the parking status of trains. This not only reduces the workload of operators but also significantly improves inspection and maintenance efficiency, enhances the reliability and accuracy of management, and greatly improves the overall safety and efficiency of the system, thus achieving the goal of reducing manpower and increasing efficiency.
