Abstract

The application provides a brake cylinder monitoring device, a system and a 25t axle load aluminum alloy coal hopper car. The 25t axle load aluminum alloy coal hopper car includes an end wall vertical plate, a support plate and a bottom plate. The brake cylinder monitoring device includes: a strain gauge pressure sensor, a pressure switch and a control device. The strain gauge pressure sensor is arranged in the installation space surrounded by the vertical plate of the end wall, the support plate and the bottom plate. The strain gauge pressure sensor communicates with the brake cylinder of the 25t axle load aluminum alloy coal hopper car. The pressure switch is arranged in the installation space. The pressure switch communicates with the brake cylinder of the 25t axle load aluminum alloy coal hopper car. The pressure switch is used to determine whether to output a trigger signal according to the pressure value of the brake cylinder. The control device is electrically connected with the strain gauge pressure sensor and the pressure switch respectively. When the control device receives the trigger signal, the control device enters the working state from the sleep state, and detects the current pressure value in the brake cylinder through the strain gauge pressure sensor, and outputs the current pressure value.

Description

technical field [0001] The application relates to the technical field of railway wagons, in particular to a brake cylinder monitoring device, a system and a 25t axle load aluminum alloy coal hopper car. Background technique [0002] Railway transportation is characterized by high efficiency and environmental protection. With the development of the world economy, railway transportation can more and more reflect its advantages. With the rapid development of the world economy, the abundant transportation of bulk goods such as minerals, grains, and chemical raw materials has created a solid and stable material foundation for the long-term and efficient operation of world rail freight. [0003] During the operation of the railway freight vehicle, it is necessary to check the pressure of the brake cylinder pressure pipe of the railway freight vehicle. At present, the pressure detection of the pressure pipe of the brake cylinder of the railway freight vehicle is to determine wheth...
