Detailed Description
In the first embodiment, the first embodiment is described with reference to fig. 2 to 6, and the first embodiment designs a braking electrical command control system capable of covering a rescue working condition and a rescued working condition, so that braking control of a vehicle under the rescue and rescued working conditions is safer and more reliable.
Aiming at the motorcycle type in China, the functions of rescuing the existing motor train unit are required to be met while the locomotive rescue is returned and the existing motor train unit is rescued, so that a new brake electrical instruction control system under the rescue working condition is required to be developed for the renaturation motor train unit of the brake system designed by a single tube, the interface is required to be clear, the structure is simple, and the universal practicability is realized. The concrete composition is as follows: the rescue control circuit comprises a return rescue control circuit 1, a rescued working condition braking instruction output circuit 2 and a rescue working condition braking instruction input circuit 3.
Referring to fig. 4, the loopback rescue control circuit 1 is composed of an independent power supply BD1-1 and a rescue/rescued mode selection switch 1-2. The independent power supply 1-1 is a special power supply for rescue/rescued working conditions, the power supply directly supplies power to the storage battery, and the power supply still outputs DC110V under the condition that a storage battery switch is closed.
The rescue/rescued mode selection switch 1-2 is a manual selection switch, and is provided with three-gear selection, namely a rescue position, a 0 position and a rescued position; the rescue/rescued mode selection switch has three control functions:
1) the switch can control the power supply of the independent power supply 1-1 to the rescue loopback device through the on-off control of the switch contact, and the rescue loopback device can be powered only when the switch is at a rescue/rescued position, so that the waste of the electric quantity of the storage battery and the generation of error instructions to a vehicle by the rescue loopback device are avoided;
2) the switch signals of the two gears of the rescue position and the rescued position of the switch are also output to the rescue returning device and are used for respectively activating the rescue and rescued functions of the rescue returning device.
3) When the switch is positioned at the rescue/rescued position, the switch means the activation of the rescue returning device, at the moment, the vehicle brake controller at the hitching end fails, and the rescue returning device replaces the function of the brake controller to generate a brake control command for the vehicle.
The embodiment is described with reference to fig. 5, and the rescued working condition braking instruction output circuit 2 is composed of 1 group (4) of one-way diodes 2-1, a braking instruction relay 2-2, 1 group (4) of one-way diodes 2-3 and a driver handle braking instruction control circuit 2-4. The unidirectional diode 2-1 has the function of ensuring the unidirectionality of the output signal of the rescue loopback device and avoiding the influence of the brake instruction control circuit 2-4 of the handle of the driver controller on the rescue loopback device. A one-way diode 2-3 is also arranged in the vehicle circuit, so that the influence of the rescue loopback circuit on the conventional circuit of the vehicle is avoided. The brake command relay 2-2 receives the brake command of the vehicle brake controller under the non-rescue working condition and transmits the brake command to each brake control device through a train line penetrating through the whole train; under the rescue working condition, the vehicle brake controller fails, and the brake command relay 2-2 receives the brake command of the rescue returning device and transmits the brake command to each brake control device through a train line penetrating through the whole train. The B1/B2/B3 line is a brake command coding line, and the Braking line is a brake state command line.
Referring to fig. 6, the rescue finger operating condition brake command input circuit 3 is composed of a passive normally open contact 3-1 of a brake command train line relay arranged in each compartment of the whole train and a part of electric wires. The set of passive contacts is connected between the rescue/rescued mode selection switch and the rescue loopback device, and is capable of encoding braking commands of 0-7 levels and braking state commands and transmitting the commands to the rescue loopback device. When the vehicle is in the rescue working condition, the circuit can transmit the brake command sent by the brake controller to the rescue returning device, and the rescue returning device activates the rescue working condition and transmits the brake command to the rescued motor train unit at the other end of the train pipe in the form of compressed air through the train pipe.
In the control system of the embodiment, the brake controller and the brake control device are both in the prior art, are produced by multiple suppliers in China, and are widely applied to the renaming motor train unit in China. Typical brake controllers such as S359 series brake controllers manufactured by the west sha er bao electric limited company, and typical brake control devices such as TKD604 series brake control devices manufactured by the beijing crossbar electromechanical technology limited company are all suitable for the motor train unit back rescue brake command control system described herein.
