Embodiment Construction

[0016] now attached figure 1 to attach Figure 5 A further description of the invention, such as figure 1 As shown, two locomotives with the same structure are reconnected. Generally, the first locomotive is the traction locomotive, and the locomotive that issues control instructions to the running status of each reconnected locomotive is the local locomotive. Issue control commands to other locomotives running status. The locomotive whose running status is controlled by the leading locomotive is the supplementary locomotive. The measurement point of the sensor is located at the connection between the supplementary machine and the air supply system of the passenger car, so that the air supply pressure value of the passenger car can be displayed. Usually, the display meters (A and B) are respectively installed in the locomotive lounge and driver's cab for real-time viewing. The driver It is necessary to check the display values ​​of the two display tables A and B on the suppl...

Abstract

The invention discloses a passenger car air supply pressure double locomotives double heading display device, the device comprises a loop 1 and loop 2 which have the same circuit structures, the loop 1 is connected with the loop 2 through a double heading socket, a terminal 1 of a display list A of the loop 1 is connected with a terminal 1 of an universal change-over switch, a terminal 2 is connected with a display list B and divides into two branches, one is connected with a sensor in series and is connected with a terminal 3 of the universal change-over switch, the other one is connected with a terminal 5 of the universal change-over switch, the terminal 3 of the display list A is connected with a terminal 7 of the universal change-over switch, the terminal 2 and a terminal 4 of the universal change-over switch of the loop 1 are connected in parallel and are connected with a terminal 2 and a terminal 4 of an universal change-over switch of the loop 2 through the double heading socket, and a terminal 6 and a terminal 8 of the universal change-over switch of the loop 1 are connected in parallel and are connected with a terminal 6 and a terminal 8 of an universal change-over switch of the loop 2 through the double heading socket; when the display device is adopted, the air supply pressure double heading display problem of the double heading locomotive is solved, and the work efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of air supply systems for passenger cars, and in particular to a dual-machine double-connection display device for air supply pressure of passenger cars. Background technique [0002] As the speed of the train continues to increase, the configuration of the vehicle is increasing day by day, and the wind used by the vehicle is also increasing. The use of air springs, sliding doors, toilets and other equipment only relies on taking air from the auxiliary air cylinder or train pipe. Increasing the burden on the locomotive air compressor affects the braking performance of the vehicle. In order to solve the above-mentioned problems, the locomotive has added an air supply pipe, and at the same time added a composite main air cylinder, which is connected with the air supply pipe to supply air to other air-using equipment of the vehicle. The added air supply pipe bypasses the automatic brake valve, and directly tak...
