Therefore, this invention proposes a braking system sensor and a railway tank car operation monitoring system for railway tank cars.

[0015] One end of the connecting rod is connected to the brake cylinder push rod displacement sensor, and the other end is provided with a tie rod fixing ring, which is connected to the floating end pin hole of the brake cylinder push rod.

[0016] Furthermore, the brake cylinder pressure sensor is connected to the brake cylinder's ventilation duct via a tee.

[0017] The main pressure sensor is connected to the main brake pipe via a tee.

[0018] The pressure sensor of the air storage cylinder is connected to the ventilation duct of the connecting valve via a tee.

[0019] This utility model also proposes a railway tank car operation monitoring system, which is special in that it includes a power supply system, an on-board gateway, a tank medium sensor, a steering sensor and a vehicle positioning system, as well as the above-mentioned braking system sensor for railway tank cars.

[0020] The power supply system is connected to the vehicle-mounted gateway via power supply wires and signal lines.

[0032] The beneficial effects of this utility model are:

[0033] [1] This utility model provides a braking system sensor for railway tank cars. By setting a brake cylinder push rod displacement sensor on the brake cylinder push rod, the sensor monitors the push rod displacement information during the braking release process, confirms the position of the push rod, and determines whether the brake cylinder has braked sufficiently and released completely. The brake cylinder pressure sensor, main pipe pressure sensor, and air reservoir pressure sensor are used to monitor the pressure of key components such as the brake cylinder, brake main pipe, and air reservoir during the braking release process. By observing the pressure change trend, the sensor determines whether the braking system is working normally, effectively improving the monitoring accuracy of the system, timely obtaining the movement status information of the tank car, providing detailed and accurate monitoring information for the staff, timely troubleshooting, ensuring the normal operation of the system, and effectively improving the safety and stability of the system.

[0034] [2] This utility model can monitor the braking system in real time through the braking system sensor, quickly determine whether the braking system function is normal, and greatly improve the safety of the system operation process. By monitoring the pressure of the brake cylinder, the main brake pipe and the air reservoir in real time, it can be determined whether the pressure of each brake component meets the requirements. When the pressure does not meet the requirements, the location of the brake system fault can be preliminarily determined by judging the pressure relationship between the three. During the braking system release process, by monitoring the pressure of the brake cylinder, the main brake pipe and the air reservoir in real time, it can be determined whether the brake cylinder release speed meets the requirements. When a non-release fault occurs, the location and type of fault information can be quickly determined by judging the pressure relationship between the three, which effectively improves the monitoring efficiency and saves the monitoring time.

[0035] [3] This utility model provides a railway tank car operation monitoring system. By setting corresponding monitoring sensors at different locations on the railway tank car, the system monitors the operation information of the railway tank car in real time through each monitoring sensor and transmits the data to the on-board gateway and host computer for data processing in real time, thereby obtaining real-time and reliable monitoring data information. This effectively improves the safety performance of vehicle transportation. The real-time monitoring of the railway tank car data information allows users to understand the operation status of the railway tank car in a timely and convenient manner, which facilitates the management, use and maintenance of the railway tank car and effectively saves management resources and maintenance costs.

Detailed Implementation

[0042] like Figure 1 As shown, a braking system sensor for railway tank cars includes a brake cylinder push rod displacement sensor, a brake cylinder pressure sensor, a main pipe pressure sensor, and a reservoir pressure sensor.

[0044] The brake cylinder pressure sensor 2 is installed on the ventilation duct connecting the brake pressure relief valve 7 and the brake cylinder 5. It is connected to the ventilation duct of the brake cylinder 5 through a tee and is used to monitor the pressure inside the brake cylinder 5 during the brake release process.

[0047] Brake cylinder pressure sensor 2, main pipe pressure sensor 3, and air reservoir pressure sensor 4 monitor the pressure of key components such as brake cylinder 5, main brake pipe 8, and air reservoir 9 in real time during the brake release process. By observing the pressure change trend, the system determines whether it is working properly and whether there is any leakage.

[0048] During the braking process, real-time monitoring of the pressure in brake cylinder 5, main brake pipe 8, and air reservoir 9 can determine whether the pressure of each braking component meets the requirements. When the pressure does not meet the requirements, the location of the braking system fault can be preliminarily determined by judging the pressure relationship between the three components. During the braking release process, real-time monitoring of the pressure in brake cylinder 5, main brake pipe 8, and air reservoir 9 can determine whether the release speed of brake cylinder 5 meets the requirements. When a non-release fault occurs, the location and type of fault can be quickly determined by judging the pressure relationship between the three components, effectively improving monitoring efficiency, saving monitoring time, and enhancing the safety of the operation process.

The on-board gateway 12 is connected to the in-tank medium sensor, the braking system sensor, the steering sensor, and the vehicle positioning system via power supply wires and signal lines. The on-board gateway 12 is used for communication with an external host computer. The power supply system 11 provides power to the in-tank medium sensor, the braking system sensor, the steering sensor, and the vehicle positioning system via the power supply wires and the on-board gateway 12.

The main pipe pressure sensor 3 is installed on the main ventilation duct of the railway tank car to monitor the air pressure within the main ventilation duct during brake release. The reservoir pressure sensor 4 is installed on the reservoir 9 of the railway tank car to monitor the air pressure within the reservoir 9 during brake release. These braking system sensors are used to monitor data related to the pressure of brake cylinder 5, the displacement of brake cylinder 5, the main pipe pressure, and the pressure of the reservoir 9 during brake release.
