Abstract
Description
Technical Field
[0001] This utility model relates to the field of identification device technology, and more specifically, to a novel railway car number identification device for identifying empty and loaded cars. Background Technology
[0002] In railway transportation, the load status of vehicles is crucial for scheduling and management. Currently, railway staff mainly rely on manual empty / loaded car adjustment devices to understand the load status of vehicles. However, manual empty / loaded car adjustment cannot accurately adjust the brake cylinder pressure based on the actual operating speed and load of the vehicle, resulting in inaccurate braking distance calculations and potential accident risks. In situations with large train formations, staff need to check and adjust the empty / loaded status of each vehicle individually, which is time-consuming and labor-intensive, and cannot guarantee the reliability and real-time nature of the data. This method relies too heavily on the experience and judgment of staff, is prone to errors, and is cumbersome and inefficient. To address the shortcomings of existing technology, we propose a novel railway car number identification device for identifying empty / loaded vehicles. Utility Model Content
[0003] In order to overcome the above-mentioned defects of the prior art, this utility model provides a new railway car number identification device for identifying empty and loaded cars, so as to solve the problem that the manual empty and loaded car adjustment device relies too much on the experience and judgment of the staff, which is prone to errors, and is also cumbersome to operate and inefficient.
[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a novel railway car number identification device for identifying empty and loaded cars, including a track, a first fixed bracket and a second fixed bracket fixedly installed on the outer wall of the track, a wheel sensor fixedly installed on the upper outer surface of the first fixed bracket, a shear force sensor fixedly installed on one side outer surface of the second fixed bracket, a radio frequency antenna provided on one side of the shear force sensor, and Z-shaped fixing frames fixedly installed on both sides of the radio frequency antenna.
[0005] The wheel sensor is provided in two parts, and the two wheel sensors are respectively located on both sides of the shear force sensor.
[0006] The radio frequency antenna is positioned between two tracks and is fixedly mounted on the ground using a Z-shaped mounting bracket.
[0007] The wheel sensor is electrically connected to the BT-510 vehicle number host via a magnetic wire, and the shear force sensor is electrically connected to the BT-510 vehicle number host via a signal line. An industrial control computer is connected to one side of the BT-510 vehicle number host via a serial cable. The industrial control computer is equipped with host computer processing software, which identifies and matches the vehicle number information and the empty / loaded status of the vehicle.
[0008] Compared with the prior art, the beneficial effects of this utility model are:
[0009] This invention incorporates a shear force sensor. When a train passes over the track, the wheel sensors control the car number host's power amplifier to determine the vehicle's speed. The shear force sensor deforms during this process, and the deformation signal is transmitted to the car number host via a control signal line. Software on the industrial control computer then determines the vehicle's load status. Simultaneously, a radio frequency antenna receives the vehicle's tag information, ensuring that the car number and load status are matched. This structure enables automatic identification of vehicle weight and type, optimizing train formation and scheduling. It significantly improves operational efficiency while ensuring data reliability and avoiding errors caused by manual operation. This novel car number identification device also promotes intelligent vehicle management. By automatically matching the identification of whether a car is empty or loaded with the car number, it accurately grasps the basic information of each car. Furthermore, through integration with IoT and big data technologies, it provides precise data support for railway transportation, optimizing transportation routes, improving resource utilization, and playing a crucial role in reducing railway costs.

[0016] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.
[0017] As attached Figure 1 To be continued Figure 4This utility model provides a novel railway car number identification device for identifying empty and loaded cars, including a track 1. A first fixed bracket 2 and a second fixed bracket 4 are fixedly installed on the outer wall of the track 1. A wheel sensor 3 is fixedly installed on the upper outer surface of the first fixed bracket 2. A shear force sensor 5 is fixedly installed on one outer surface of the second fixed bracket 4. A radio frequency antenna 6 is provided on one side of the shear force sensor 5. Z-shaped fixing brackets 7 are fixedly installed on both sides of the radio frequency antenna 6.
[0018] The wheel sensor 3 controls the power amplifier of the vehicle number host to determine the vehicle speed. When the train passes over track 1, the shear force sensor 5 will deform. The deformation signal is uploaded to the vehicle number host through the control signal line. Then, the software on the industrial control computer determines the vehicle's load condition. At the same time, the radio frequency antenna 6 receives the vehicle's tag information, thereby ensuring that the vehicle number and load condition are matched. This realizes automatic identification of vehicle weight and type, optimizes train formation and scheduling, ensures data reliability, greatly improves work efficiency, and avoids errors caused by manual operation.
[0019] There are two wheel sensors 3, which are respectively located on both sides of the shear sensor 5.
[0020] The radio frequency antenna 6 is positioned between the two tracks 1 and is fixedly installed on the ground by a Z-shaped bracket 7.
[0021] Among them, the wheel sensor 3 is electrically connected to the BT-510 vehicle number host via a magnetic wire, the shear force sensor 5 is electrically connected to the BT-510 vehicle number host via a signal line, and one side of the BT-510 vehicle number host is connected to an industrial control computer via a serial cable. At the same time, the industrial control computer is equipped with host computer processing software, which identifies and matches the vehicle number information and empty / loaded vehicle status.
[0022] The working process of this utility model is as follows:
[0023] When the train passes over wheel sensor 3 and shear sensor 5, the trigger signal of shear sensor 5 is uploaded to the BT-510 vehicle number host, causing the host to turn on its power amplifier. At the same time, radio frequency antenna 6 receives information from the electronic tag on the bottom of the vehicle. When the train runs over wheel sensor 3, the train's speed can be calculated through a specific algorithm. Shear sensor 5 deforms, and the trigger signal is uploaded to the vehicle number host through the control line. Finally, it is uploaded to the host computer software for analysis and processing.
[0024] Finally, the empty / loaded status of the vehicles, train speed, and car number information are matched through host computer software, thereby accurately grasping the basic information of each car, greatly improving operational efficiency and avoiding errors caused by manual operation. The new car number identification device for identifying empty / loaded vehicles also promotes intelligent vehicle management. Through integration with technologies such as the Internet of Things and big data, it provides precise data support for railway transportation, optimizing transportation routes and improving resource utilization.
