Description

Technical Field

[0001] The invention belongs to the technical field of vehicle detection, and in particular relates to a JSQ6 vehicle bottom height detection and warning system and a detection method. Background Art

[0002] In recent years, the number of JSQ6 vehicles arriving at marshaling yards for dismantling has gradually increased, and the JSQ6 vehicles in the dismantling trains have problems such as scattered marshaling positions and multiple destinations. Since JSQ6 vehicles are painted with "No passing the peak, no sliding" signs, they need to be sent to the marshaling yard via the detour line under the peak, which seriously affects the efficiency of hump dismantling operations.

[0003] The JSQ6 vehicle (JSQ6 concave bottom double-deck transport vehicle) has a concave bottom structure. When the JSQ6 vehicle passes through the hump slope change point and the reducer, whether the bottom of the vehicle will touch the top of the rail is directly related to the height of the lowest point of the lower part of the vehicle from the rail surface. In the JSQ6 vehicle parameters, the height of the lowest point of the lower part of the vehicle from the rail surface (empty vehicle) is 190mm, but actual tests have found that the height of the lowest point of the lower part of the vehicle from the rail surface varies greatly for different JSQ6 vehicles. Vehicles with the same height of the lowest point of the lower part of the vehicle from the rail surface in static measurements will also show different distances from the bottom of the vehicle to the rail surface during dynamic operation. When the JSQ6 vehicle passes through the hump slope change point, whether the bottom of the vehicle will touch the top of the rail is directly related to the height of the lowest point of the lower part of the vehicle from the rail surface.

[0004] When a vehicle passes through the top of a hump, the space under the vehicle will be reduced. Theoretically, when a JSQ6 vehicle passes through a hump, the space under the vehicle is already small. Combined with the horizontal and height deviations of the line caused by untimely maintenance of the hump, the space under the vehicle may be further reduced. Considering factors such as wear of vehicle components, loading, and spring compression caused by vehicle vibration, the distance between the vehicle concave bottom and the top surface of the rail becomes the main factor restricting whether the vehicle can pass through the hump.

[0005] To address this problem, a device that can automatically measure and identify the minimum distance to the bottom of JSQ6 vehicles was developed to meet the safety production requirements for JSQ6 vehicles passing through peak hours. Summary of the invention

[0006] The purpose of the present invention is to overcome the problem that when the existing JSQ6 model passes over a hump, the vehicle cannot pass smoothly due to the small space under the vehicle, causing the vehicle to be stuck or damaged, and to provide a JSQ6 model vehicle bottom height detection warning system and detection method.

[0007] In order to achieve the above object, the present invention adopts the following technical solution: A JSQ6 vehicle bottom height detection and warning system comprises rails, an approach device and a laser rangefinder are installed close to the inner side of the rails, the laser rangefinder and the approach device are arranged at intervals, the approach device and the laser rangefinder are connected to a main control cabinet, and the main control cabinet comprises an alarm module.

[0008] It comprises a first bracket, the approaching device is clamped on the rail through the first bracket, and a detection box is installed on the inner side of the rail.

[0009] The detection box is used to detect whether there is a vehicle passing on the rails, and can generate a pulse signal when a vehicle passes.

[0010] The laser rangefinder is clamped on the rail through the second bracket, the laser rangefinder is installed on the inner side of the rail, and a wiper is installed on the top of the laser rangefinder; The laser rangefinder comprises a heating module, a temperature control switch and a rangefinder module; The heating module is connected to a temperature control switch, and when the ambient temperature is lower than a preset temperature, the heating module performs heating; The distance measuring module is used to collect the distance between the bottom of the vehicle and the upper surface of the rail.

[0011] The laser rangefinder is a laser rangefinder based on triangulation.

[0012] The outer shell surface of the top of the laser rangefinder adopts a glass mirror light-transmitting surface, and the glass mirror light-transmitting surface is installed obliquely.

[0013] A static calibration device is installed on the side of the laser rangefinder, and the static calibration device is used to calibrate the distance between the upper surface of the rail and the bottom of the vehicle. The static calibration device is connected to the main control cabinet.

[0014] The main control cabinet includes a first calibration button and a second calibration button. The first calibration button is used to control the static calibration device to calibrate the distance between the upper surface of the rail and the bottom of the concave surface of the vehicle bottom. The second calibration button is used to control the static calibration device to calibrate the distance between other parts of the concave surface of the vehicle bottom and the upper surface of the rail.

[0015] A JSQ6 vehicle bottom height detection and early warning method, specifically using the following method: The proximity device detects whether there is a vehicle passing on the rail. When the proximity device detects the presence of a vehicle, it transmits a signal. The main control cabinet receives the signal and controls the laser rangefinder to measure the distance between the bottom of the vehicle and the upper surface of the rail. The main control cabinet collects the measurement data. When the measured data is lower than the preset distance, an alarm is issued and the staff adjusts the height of the vehicle.

[0016] Laser rangefinder uses 1KH Z High frequency acquisition.

[0017] Compared with the prior art, the present invention has the following beneficial effects: The present invention provides a JSQ6 vehicle bottom height detection and early warning system, comprising a rail, an approaching device and a laser rangefinder are installed close to the inner side of the rail, the approaching device and the laser rangefinder are arranged at intervals, the approaching device and the laser rangefinder are connected to a main control cabinet, and the main control cabinet includes an alarm module.

The main cabinet collects the measurement data, and when the measured data is lower than the preset distance, an alarm is issued, and the staff adjusts the height of the vehicle. The system can monitor the distance between the bottom of the JSQ6 vehicle and the rail in real time, ensuring that the vehicle will not touch the rail when passing through key areas such as hump slope change points, thereby avoiding the interruption of operations caused by vehicle jamming or damage, and significantly improving the efficiency of hump dismantling operations. At the same time, through the early warning function, the system can notify the staff in time before potential danger occurs, reducing the possibility of accidents and ensuring the safety of the operators.

[0018] Furthermore, the present invention can cope with the changes in the height of the lowest point of the lower part of the body of different JSQ6 vehicles from the rail surface, as well as the difference between static and dynamic measurements, to ensure the accuracy and reliability of the measurement results.

[0019] Furthermore, the use of advanced equipment such as proximity devices and laser rangefinders has achieved real-time monitoring of vehicle status and automatic data collection, reducing the frequency and difficulty of manual intervention and improving the operating efficiency and accuracy of the system.

[0032] Various structural schematic diagrams of the embodiments disclosed in the present invention are shown in the accompanying drawings.

[0033] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0034] Example 1 A JSQ6 vehicle bottom height detection and warning system, the composition structure of which is as follows: like Figures 1 to 3As shown, a JSQ6 vehicle bottom height detection and warning system includes a rail 1, an approach device 2 and a laser rangefinder 3 are installed close to the inner side of the rail 1, the approach device 2 and the laser rangefinder 3 are set at a certain distance (which can be 5-80m), the approach device 2 and the laser rangefinder 3 are connected to a main control cabinet 4, and the main control cabinet 4 includes an alarm module.

[0035] The approach device 2 is clamped on the inner sides of the two lateral ends of the rail 1 through the first bracket 21. The approach device 2 includes a detection box 22. The detection box 22 is used to detect whether there is a vehicle passing on the rail 1. When a vehicle passes, the detection box 22 sends a pulse signal.

[0036] The laser rangefinder 3 is clamped on the inner sides of the two lateral ends of the rail 1 through the second bracket 32. The rail 1 and the second bracket 32 ​​are fixed by a spring structure 33. The installation angle of the laser rangefinder 3 can be adjusted. The outer shell surface emitting the laser is made of a glass mirror translucent surface. The outer shell and the glass mirror translucent surface are installed in an inclined manner. The inclined installation of the outer shell surface is used to reduce dust, reduce the area where rainwater falls, and facilitate cleaning of the mirror surface.

[0037] The laser rangefinder 3 includes a heating module, a temperature control switch and a ranging module. The accuracy requirements of the outdoor equipment and the ranging module are 1 mm, and the temperature is above 30°C. However, since the outdoor temperature is relatively low in winter, the laser rangefinder 3 cannot meet the measurement temperature requirements. When the main control cabinet 4 detects that the temperature is too low, the temperature control switch is turned on to heat the heating module. When the temperature reaches 30°C, the heating is automatically disconnected. In order to prevent rain and mud from accumulating on the glass translucent surface of the laser rangefinder 3, resulting in the inability to measure the distance, a wiper 31 is installed on the outer side of the glass translucent surface of the laser rangefinder 3. The wiper 31 is controlled by the main control cabinet 4. When the vehicle approaching device 2 detects a vehicle, the main control cabinet 4 controls the wiper 31 to clean once, and then clean again after the vehicle has completely passed, to reduce the risk of foreign matter residue.

[0038] Preferably, each laser rangefinder 3 is equipped with two ranging modules, and when a single ranging module is blocked or abnormal, the other ranging module can provide data support.

[0039] A static calibration device 5 is installed on the side of the laser rangefinder 3 for calibrating the distance between the upper surface of the rail 1 and the bottom of the vehicle. The static calibration device 5 is connected to the main control cabinet 4.

[0040] The main control cabinet 4 includes a first calibration button 41 and a second calibration button 42. The first calibration button 41 is used to control the static calibration device 5 to calibrate the distance between the upper surface of the rail 1 and the bottom of the concave surface of the vehicle bottom. The second calibration button 42 is used to control the static calibration device 5 to calibrate the distance between other parts of the concave surface of the vehicle bottom and the upper surface of the rail 1.

[0041] The main control cabinet 4 includes a main control module, a power module, and an optical fiber conversion module. The power module is used for power supply. The main control module is wired to the equipment in the cabinet. The optical fiber conversion module represents a network photoelectric conversion module. Long-distance transmission is carried out by armored optical fiber.

[0042] Example 2 A JSQ6 vehicle bottom height detection and warning method is as follows: When a vehicle approaches the rail 1, the detection box 22 of the approach device 2 will first detect the presence of the vehicle and send out a pulse signal, which is transmitted to the main control cabinet 4. The main control cabinet 4 sends out a distance measurement instruction. After receiving the instruction from the main control cabinet 4, the laser rangefinder 3 turns on the temperature control switch and controls the heating module to heat up. The wiper 31 works. After heating to 30°C, it emits a laser and measures the distance between the bottom of the vehicle and the upper surface of the rail 1. The main control cabinet 4 receives the data from the laser rangefinder 3 and analyzes and processes it. If the height of the bottom of the vehicle is lower than the preset safety threshold, the main control cabinet 4 will immediately trigger the alarm module and send out an audible and visual alarm to notify relevant personnel to adjust the height of the vehicle body.

[0043] Preferably, the distance data collected by the laser rangefinder 3 is calibrated by the static calibration device 5, and the measured height data collected by the laser rangefinder 3 is compensated by a linear calibration method, and the calibration formula is: = actual value; in and is the calibration coefficient, calculated using the collected data, The data collected by the laser rangefinder 3 is used to calculate a measurement result closer to the actual value through a calibration formula, thereby avoiding deviations caused by installation height and angle problems and improving measurement accuracy.

[0044] Preferably, the laser rangefinder 3 is provided by 1KH Z High-frequency data collection can restore the height curve of the vehicle bottom to a large extent. For vehicles with a speed of 50KM / h, a height value can be output at intervals of 13.8mm. This can cover the speed of all vehicles entering the venue, and the height measurement value has also met the precise requirements.

[0045] Preferably, when there is no pulse signal from the vehicle approaching device 2 for 20 seconds, it indicates that the vehicle has completely passed, and the collection of height data is stopped.

[0046] Finally, it should be noted that the above embodiments only describe the basic principles and main features of the present invention and the advantages of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present invention is defined by the attached claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
