Description

Technical Field

[0001] The utility model relates to the field of safety supervision of railway-related projects, and in particular to a real-time monitoring integrated equipment suitable for intrusion of large-scale equipment in railway-related projects. Background Art

[0002] In railway engineering scenarios, large-scale equipment intrusion is an important part of safety control. Due to its great harm to railway transportation safety and the difficulty of prior prevention and control, it has become an important management content of railway engineering safety control. The traditional method of large-scale equipment intrusion control is mainly on-site monitoring by personnel, but personnel monitoring cannot accurately determine the distance between large-scale equipment and the railway safety boundary. If strict requirements are imposed, it will inevitably affect the normal work progress. If the on-site control requirements are relaxed, there may be problems where large-scale equipment has intruded but has not been discovered in time. At the same time, personnel control cannot control the construction activities of large-scale equipment during non-construction time periods, nor can it conduct early warning management of large-scale equipment intrusion in real time.

[0003] LiDAR has high ranging accuracy and target detection capabilities, and has a high monitoring frequency. It can automatically perform target detection tasks 24 hours a day. It has been widely used in perimeter security and other scenarios and has produced good application results. At present, detection equipment that integrates LiDAR and video cameras has begun to be tested and applied at railway tunnel entrances, high slopes and other locations to detect targets such as falling rocks and mudslides. However, due to the complexity of intrusive targets and considering detection reliability issues, the above applications are still in the testing stage.

[0004] For railway engineering projects near operating railways, there are currently few equipment for real-time monitoring of large-scale equipment intrusions. Some equipment mainly uses a single laser radar device for detection, and the detection results cannot be compared, verified, and recorded through video cameras. When a single video camera is used for detection, there are cases of missed detection, and the detection accuracy does not meet the safety management requirements of railway projects. On the other hand, the laser radar of existing detection equipment is fixed relative to the vertical pole, and the distance between the laser radar detection surface and the railway boundary cannot be adjusted. There is also a lack of structural devices to adjust the angle between the laser radar detection surface and the centerline of the railway, resulting in the detection equipment's low adaptability to scenarios and is not suitable for large-scale promotion and application in railway engineering scenarios. Utility Model Content

[0005] In order to solve the problems in the background technology, the utility model provides a real-time monitoring equipment for intrusion of large-scale equipment in railway-related projects, which can ensure monitoring accuracy, improve installation adaptability and ensure railway transportation safety.

[0006] To this end, the utility model adopts the following technical solutions:

[0007] A real-time monitoring integrated equipment for large-scale equipment intrusion in railway projects, including an adjustable crossbar assembly, a vertical bar, a distribution box, an alarm light, a camera and a laser radar, wherein:

[0008] The adjustable crossbar assembly comprises a fixed portion and a movable portion which are arranged transversely; one end of the fixed portion is fixedly connected to the top of the vertical bar, and the other end is sleeved with the movable portion;

[0009] One end of the movable part is retracted and adjusted in the fixed part, and the movable part is fixed at the retracted and adjusted position by a screw, and the other end extends outside the fixed part;

[0010] The laser radar is universally connected to one end of the mobile part away from the fixed part; the laser radar is used to detect large-scale equipment that intrudes;

[0011] The alarm light and the camera are fixed on the fixing part, the alarm light is used to send out an alarm when a large device intrudes, and the camera is used to collect on-site images;

[0012] The distribution box is fixed on the vertical pole and is used to supply power to the warning light, camera and laser radar; the camera and laser radar transmit data through the distribution box;

[0013] The distribution box includes an industrial computer and a router. The industrial computer is used to receive and process the data from the laser radar, and send an alarm signal to the alarm light when a large device infringes the limit. The camera transmits the collected on-site images to the host computer through the router.

[0014] Preferably, a plurality of square iron sheets are welded on the top of the vertical rod, and the end of the adjustable cross bar assembly close to the vertical rod is fixedly connected to the square iron sheets by bolts, and the position of the adjustable cross bar assembly can be adjusted by connecting the adjustable cross bar assembly to the square iron sheets at different positions.

[0015] Preferably, the alarm emitted by the alarm light when a large device intrudes into the limit includes an audible alarm and a light alarm.

[0016] Preferably, the camera includes a first camera and a second camera; the first camera and the second camera are used to capture live images at different angles.

[0017] Preferably, the laser radar is connected to the end of the mobile part away from the fixed part through a three-dimensional universal joint, and the three-dimensional universal joint is used to adjust the angle between the detection surface of the laser radar and the center line of the railway to ensure that the center line of the railway remains parallel to the detection surface of the laser radar.

[0019] Preferably, the angle between the viewing angle of the first camera and the horizontal plane is 0°, and the angle between the viewing angle of the second camera and the horizontal plane is 30°.

[0020] Compared with the prior art, the utility model has the following beneficial effects:

[0021] 1. The utility model has a reasonable, stable and highly integrated design, which reduces the signal transmission problems caused by the independent deployment of multiple devices for data collection, data settlement and on-site alarm, as well as the problem of untimely alarm, and provides a new technical defense means for the safety management and control of railway-related projects, significantly improves the safety management and control level of railway-related projects, and ensures the safety of railway transportation.

[0022] 2. The utility model solves the problem that the position of the laser radar in traditional equipment cannot be moved, which requires the reconstruction of the vertical pile foundation. It improves the flexibility of selecting the on-site installation position of the equipment and improves the adaptability of the equipment to the complex environment of railway engineering construction.

[0023] 3. In the utility model, a three-dimensional universal joint component is integrated, which can dynamically adjust the relative geometric relationship between the laser radar detection surface and the center line of the railway. If the three-dimensional universal joint structure is not added to the equipment, other measuring equipment is required to assist in the installation because the installation of the vertical rod needs to ensure a high position accuracy and ensure that the laser radar detection surface remains parallel to the center line of the railway, which increases the difficulty of on-site installation of the equipment. On the other hand, if it is found that the detection surface is not parallel to the center line of the railway after the equipment is fixed to the ground, the requirements of the warning distance are not met, and the vertical rod needs to be readjusted, thereby increasing the investment in manpower and material costs. Therefore, the design of the utility model can significantly reduce the difficulty of on-site installation of equipment, improve the efficiency of on-site installation of equipment, and has more universal promotion value.

[0024] 4. The utility model integrates two devices, a laser radar and a camera. On the one hand, the camera can compare and verify the detection results of the laser radar to ensure the reliability of the results; on the other hand, based on the on-site images captured by the camera, it can provide prior information for the laser radar detection under rainy conditions to improve the detection accuracy.

[0030] The technical solution of the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0031] like Figure 1 As shown, the real-time monitoring integrated equipment for intrusion of large-scale machinery in railway projects of the utility model includes an adjustable cross bar assembly 1, a vertical bar 2, a distribution box 3, an alarm light 4, a camera 5 and a laser radar 6.

[0032] like Figure 2 As shown, the adjustable crossbar assembly 1 includes a fixed portion 7 and a movable portion 8. The fixed portion 7 is arranged horizontally (horizontally or nearly horizontally), one end of the fixed portion 7 is fixedly connected to the top of the vertical bar 2, and the other end is sleeved with the movable portion 8 inside. The movable portion 8 can be retracted and adjusted in the fixed portion 7, and after the distance is adjusted, it is locked by screws to fix the movable portion 8 in the retracted and adjusted position.

[0033] In one embodiment of the utility model, the fixed part 7 with a length of 335mm is fixedly connected to the vertical rod 2 by welding on the square iron sheet at the top of the vertical rod 2, and is specifically assembled by bolts and tapping the square iron sheet welded on the top of the vertical rod. The bottom of the vertical rod 2 is fixed to the ground by 4 bolts; the length and width of the square iron sheet are 100mm*100mm, and the thickness is 3mm. The alarm light 4 and the camera 5 are fixed on the fixed part; a three-dimensional universal joint 9 is provided at one end of the mobile part away from the fixed part; the alarm light and the camera are assembled with the fixed part by screws.

[0034] The camera 5 includes a first camera 5-1 and a second camera 5-2. The first camera 5-1 and the second camera 5-2 receive the laser radar intrusion detection signal through the industrial computer 11, capture the image and transmit it to the host computer;

[0035] The first camera 5-1 and the second camera 5-2 are wide-angle cameras, and they have different observation angles. The two cameras observe the detection area in the same direction. In one embodiment of the utility model, the angle of view of one camera with the horizontal plane is 0°, and the angle of view of the other camera with the horizontal plane is 30°. To ensure the reliability of the detection results, when the laser radar equipment detects an intruding target, the two cameras can synchronously take photos of the scene, and the photos can be used to verify the detection results and keep records.

[0036] The laser radar 6 is fixedly connected to the free end of the three-dimensional universal joint 9 through the adapter plate 10; the movable part 8 is used to adjust the distance from the detection surface of the laser radar 6 to the railway pipe boundary, and the telescopic adjustable length of the movable part is 250mm; the three-dimensional universal joint is used to adjust the angle between the detection surface of the laser radar 6 and the center line of the railway to ensure that the center line of the railway remains parallel to the detection surface of the laser radar.

[0037] One side of the three-dimensional universal joint 9 is screwed to the free end of the moving part, and the other side is screwed to the adapter plate; the laser radar is screwed to the adapter plate.

[0038] The laser radar 6 is a multi-line laser radar. In order to overcome the complex on-site environment of railway-related projects, improve detection accuracy and expand the detection range, the laser radar 6 has a beam of no less than 16 lines.

[0039] Furthermore, the direction of the adjustable cross bar assembly 1 can be replaced more conveniently by welding square iron sheets in different directions; when the utility model is restricted by the on-site installation environment, the distance from the radar detection surface to the railway boundary can be flexibly adjusted by installing the adjustable cross bar assembly 1 on different square iron sheets on both sides of the vertical bar 2 and adjusting the size of the movable part inserted into the fixed part.

[0040] In the prior art, after the vertical pole is fixed to the ground, the entire device cannot be adjusted, so the relative position can only be accurately measured before being fixed to the ground so that the radar and camera can function, but this will undoubtedly increase the cost and difficulty of construction. The utility model can be installed through rough measurement. After installation, if there is a large deviation in the orientation of the laser radar or camera, it can be solved by connecting the adjustable crossbar assembly to the square iron sheet in another direction; if the laser radar needs to fine-tune the detection surface, the three-dimensional universal joint and the adjustable crossbar assembly can be used to make subtle position adjustments. The entire adjustment process is convenient and fast.

[0041] like Figure 3 and Figure 4 As shown, the distribution box 3 is arranged on the upper part of the vertical pole, and is fixed to the vertical pole 2 by two clamp brackets and a stainless steel clamp ring (not shown in the figure).

[0042] The distribution box 3 includes an industrial computer 11, a router 19, a fiber optic transceiver 12, a power supply 13, an air switch 14, a guide rail 15, a relay 16, a graphics card cheater 17 and a data interface connector 18, wherein:

[0043] The industrial computer 11, router 19, fiber optic transceiver 12, power supply 13, guide rail 15, and relay 16 are fixed in the distribution box by bolts. The graphics card spoofer 17 and data interface connector 18 are connected to the jack of the industrial computer 11. The air switch 14 is fixed to the guide rail by the card slot at the bottom. The fiber optic transceiver 12 is connected to the router 19 and is bolted to the bottom of the distribution box. The wires of the integrated components in the distribution box are all led out through the through holes at the bottom of the distribution box.

[0044] The industrial computer 11 receives the laser radar data for processing. When a large device infringes the limit, it sends an alarm signal to the alarm light 4. The alarm light 4 lights up and plays an alarm sound and flashes the light synchronously. The color of the alarm light cannot be red, and the color is generally yellow. The alarm light 4 is connected to the industrial computer 11 via a USB cable.
