Description

Technical Field

[0001] The invention relates to the technical field of monitoring the inner-supported parking anti-slip device, in particular to a three-in-one intelligent monitoring system for the inner-supported parking anti-slip device. Background Art

[0002] Internal support parking anti-slip devices are usually installed in railway station lines, section pipelines, branch lines, marshalling yards and special-purpose lines. They are mainly used to prevent trains from slipping when they are stopped.

[0003] However, the internal support parking anti-slip device currently used has some disadvantages:

[0004] When the internal transmission structure fails, the operator needs to go to the site to manually brake or relieve the load. This will increase safety risks due to delayed problem discovery and on-site operations.

[0005] Therefore, a three-in-one intelligent monitoring system for internally supported parking anti-slip devices is proposed. Summary of the invention

[0006] In order to solve the problems existing in the prior art, the present invention provides a three-in-one intelligent monitoring system for an internally supported parking anti-slip device to solve the technical problems raised in the above background technology section.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] The three-in-one intelligent monitoring system for the internal support parking anti-slip device proposed in the present invention comprises a control cabinet, a control terminal, a display screen and a monitoring system;

[0009] The monitoring system includes a switch monitoring system, a pressure sensor monitoring system, and a video transmission monitoring system. Through the combined monitoring of the switch monitoring system, the pressure sensor monitoring system, and the video transmission monitoring system, real-time monitoring of the working status of the equipment is achieved. The switch monitoring system, the pressure sensor monitoring system, and the video transmission monitoring system transmit signals to the control terminal, and the control terminal makes corresponding operations.

[0010] Preferably, the in-position switch monitoring system includes an in-position switch, which is placed in an internally supported parking anti-slip device. When the internally supported parking anti-slip device is in a braking or release state, the in-position switch changes state in real time and transmits the state to a control cabinet. The state information is then converted into an optical fiber signal through a conversion module of the control cabinet and transmitted to a remote control terminal to indicate the current working state of the parking device - braking or release, thereby achieving the purpose of monitoring the working state.

[0011] Preferably, the pressure sensing monitoring system includes a pressure sensor, which is embedded in the spring box of the internally supported parking anti-skid device. During the spring change process of the internally supported parking anti-skid device, the pressure data is measured and the piezoelectric signal is converted into a digital signal through a transmitter, which is transmitted remotely to a local control cabinet, converted into an optical fiber signal through a switch, and transmitted to a remote control terminal. The quality of braking or relief of the parking device and whether the train moves during the parking process are monitored in real time through the changes in pressure values.

[0012] Preferably, the video transmission monitoring system includes a monitoring camera, which takes real-time video of the running status of the brake rail, and transmits the video data obtained by the control software to the control cabinet, and then converts it into an optical fiber signal through a switch and synchronously transmits it to the control terminal. At the remote monitoring terminal, the working status of the on-site parking device can be monitored in real time.

[0013] Compared with the prior art, the beneficial effects of the present invention are: the "three-in-one intelligent monitoring" system of the internally supported parking anti-slip device in the present invention solves this drawback very well. Through real-time monitoring and automatic remote operation, it reduces the intensity of manual work, reduces operational risks, and improves the operational efficiency of parking anti-slip.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] The present invention provides a three-in-one intelligent monitoring system for an internally supported parking anti-slip device, comprising a control cabinet, a control terminal, a display screen and a monitoring system. The monitoring system comprises an in-place switch monitoring system, a pressure sensor monitoring system and a video transmission monitoring system. Through the combined monitoring of the in-place switch monitoring system, the pressure sensor monitoring system and the video transmission monitoring system, real-time monitoring of the working status of the equipment is achieved. The in-place switch monitoring system, the pressure sensor monitoring system and the video transmission monitoring system transmit signals to the control terminal, and the control terminal performs corresponding operations.

[0019] The details are as follows:

[0020] like Figure 1 As shown, the in-position switch monitoring system includes an in-position switch, which is placed in the internal support parking anti-slip device. When the internal support parking anti-slip device is in the braking and release state, the in-position switch changes the state in real time and transmits the state to the control cabinet. Then, the state information is converted into an optical fiber signal through the conversion module of the control cabinet and transmitted to the remote control terminal to indicate the current working state of the parking device - braking or release, thereby achieving the purpose of monitoring the working state.

[0021] like Figure 2 As shown. The pressure sensing monitoring system includes a pressure sensor, which is embedded in the spring box of the inner-support parking anti-slip device. During the spring change process of the inner-support parking anti-slip device, the pressure data is measured and the piezoelectric signal is converted into a digital signal through a transmitter, which is transmitted to the local control cabinet, converted into an optical fiber signal through a switch, and transmitted to the remote control terminal. Through the change of the pressure value, the quality of the parking device braking or relief in place and whether the train moves during the parking process are monitored in real time, and the slipping event is controlled in the early stage and intervened, which effectively prevents the occurrence of malicious events.

[0022] like Figure 2 As shown in the figure, the video transmission monitoring system includes a monitoring camera installed on the inner support parking anti-skid device. The monitoring camera is installed 1 meter away from the central axis of the non-motor end parking device. The monitoring camera takes real-time video of the running status of the brake rail. The video data obtained by the control software is transmitted to the control cabinet, and then converted into optical fiber signals through the switch and synchronously transmitted to the control terminal. At the remote monitoring terminal, it is possible to monitor in real time whether the working status of the on-site parking device is stable and whether any abnormal situation occurs. When an abnormal situation is found, an alarm can be immediately issued, and the on-duty personnel can perform error correction operations. The occurrence of the skidding incident is controlled in the early stage and intervened, which effectively prevents the occurrence of malicious incidents.

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

[0024] This monitoring system has two major functions: detection and alarm. It is used to provide a reliable real-time monitoring method. Through pressure measurement and image comparison, it can instantly determine whether the braking and mitigation of the internal support type anti-skid parking device are effective. At the same time, it notifies the risk through voice and picture alarms, which is convenient for staff to quickly and accurately locate and troubleshoot problems, thereby further improving the reliability of the internal support type parking anti-skid device and greatly reducing the risk of skidding or blocking caused by factors such as transmission failure.

[0025] In practice, if Figure 3As shown, the internal support anti-slip parking device adopts a "2+2" parking device installation scheme, which has the advantage of being able to meet the parking needs of long and short trains. The control cabinet includes control cabinet A and control cabinet B. Control cabinet A independently controls equipment 1-2; control cabinet B independently controls equipment 3-4, but the data of 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-slip parking device, including a pressure sensor and a signal transmitter, as well as an auxiliary real-time monitoring camera, a signal control cabinet installed near the track line, and monitoring software installed in the control cabinet and the control terminal. The information transmitted by the signal transmitter is converted into network transmission through a signal converter, and is connected to the network switch at the same time as the monitoring data, and is transmitted to the control cabinet and the signal building through optical fiber. Each group of parking devices is equipped with a total of six spring boxes, each of which is equipped with a coaxial pressure sensor, and the spring box is installed on the brake base beam installed perpendicular to the brake rail. At the same time, each group of parking devices is equipped with a high-definition monitoring camera in front of it. The camera is installed on the central axis of the parking device parallel to the brake arm, one meter away from the outermost brake base beam.

[0027] The normal working process of the internal support parking anti-skid device is that when the train stops steadily on the track line, the braking operation is started, the motor drives the brake arm to rise and extend to both sides, clamping the wheel rim of the train until the brake is in place, a brake in place signal is issued, and the motor stops rotating; when the train needs to move, the release operation is started, the motor drives the brake arm to retract inward and lower it to the initial position, and a release in place signal is issued, and the motor stops rotating. When the brake transmission mechanism fails, the above process may have the following risks:

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

[0029] (2) After the brake in place signal is generated, the brake arm does not clamp the wheel rim or the braking force generated is not sufficient;

[0030] (3) The relief cannot be achieved within the prescribed time;

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

[0032] To solve the above problems, this monitoring system does the following:

[0033] (1) The monitoring software obtains the action signal sent by the parking anti-skid control system in real time. When the braking or release action signal is obtained, the action time begins to be calculated. According to TB / T 3162.1-2007, the braking time or release time must not exceed 30 seconds. If the control system does not send a braking or release signal within the specified time, the monitoring software will issue an interface and voice alarm to prompt the action timeout;

[0034] (2) According to the actual working situation, we need to preset the incremental threshold that the pressure should obtain when braking is normal. The monitoring software obtains the pressure value measured by the pressure sensor in real time. When the monitoring software obtains the start braking signal sent by the control system of the parking guard, the monitoring software will use the pressure value measured before the start action as the comparison baseline value, and retain the current working condition photo 1. When normal braking is in place, the pressure value closest to the wheel position has the largest increment, and the pressure value far away from the wheel position has a smaller increment, or even decreases instead of increasing. Through this phenomenon, we can more accurately determine the wheel's position when pressing the car. If the maximum increment is less than the incremental threshold that should be obtained for normal braking, we can reasonably suspect that the braking force is not reached, and thus issue a warning;

[0035] (1) After the brake is in place, the monitoring software will automatically take and save a frame of working condition photo 2. If the sensor increment near the initial pressing position decreases significantly during parking, while the sensor increment away from the initial pressing position increases significantly, the working condition photo 2 saved when the brake is in place is 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 believe that the vehicle has undergone abnormal displacement at this time, and issue an early warning;

[0036] (2) When the monitoring software obtains the release signal sent by the control system of the parking anti-skid device in real time, if the release is normal, the difference between each pressure measurement value and the initial baseline value will not exceed a reasonable range. If it exceeds a reasonable range, the retained working condition photo 1 is retrieved for image comparison with the current real-time monitoring screen, and the structural similarity index is calculated. When the index indicates that the image has changed significantly, we can reasonably believe that the brake arm release is abnormal, and thus issue an early warning.

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

[0038] (4) The above warnings remind staff to conduct timely inspections and maintenance of equipment conditions.

[0039] The technical advantages and long-term benefits of the "three-in-one" intelligent monitoring system for internally supported parking anti-slip devices.

[0040] This system realizes digital and visual management through comprehensive real-time video monitoring and pressure sensing technology, so that the staff can obtain the real and reliable working status of the parking device and the parking status of the vehicle train. It can not only reduce the labor intensity of the operators, but also greatly improve the efficiency of detection and maintenance, enhance the reliability and accuracy of management, and greatly improve the safety and efficiency level of the whole system, thereby achieving the effect of reducing staff and increasing efficiency.
