However, as we all know, the train brake pipe not only transmits the energy of compressed air, but also transmits the braking command of the driver controller. Therefore, installing sensors on the train brake pipe, especially the flow sensor and differential pressure sensor, will have a negative The brake command transmitted by the moving tube causes interference, causing the brake system to work abnormally
Moreover, the existing detection device can only detect the air pressure and flow rate of the braking system, but cannot detect the air pressure of other air-using equipment at the same time, and cannot detect the faults of air-using equipment such as air springs and plug doors, and cannot guarantee Normal operation of the train

The detector for train compression air consumption comprises: a measurement tube in train total air-duct, the first pressure sensor arranged on outside wall of the tube by an assembly base with inner cavity connected to the tube cavity, a second pressure sensor arranged on outer wall of the tube by a base connected with inner cone tail through an L-shaped linkage pipe, and a computer connected with output of two sensors. This invention can detect the consumption of compressed gas and decides state of train break system without effect to train running.
Description
Technical field [0001] The invention relates to a detection device for railway locomotives, in particular to a detection device for the penetration state of train brake pipes and the state of other wind-using equipment Background technique [0002] Railway trains are usually braked by air brakes, and the working gas (compressed air) is connected to the rear trailer through the brake pipe (also known as the train pipe). The change of the pressure of the compressed air in the brake pipe changes the brake cylinder of each vehicle. The piston and the corresponding brake transmission mechanism drive the action of the brake shoe to realize the braking and release of the train. Both ends of each vehicle in the train are connected in series with the flexible pipes and angled plugs (i.e. special air valves) in the brake pipes to realize the opening and closing of the brake pipe passages of the front and rear vehicles. During the operation of the train, if the angle cock door is clos...
