Problems solved by technology

When the train wake-up relay (WUDYR) at either end is short-circuited, it will directly cause the circuit breaker of the local end to trip. At this time, the wake-up train line loses power, and the train power supply contactors (TSK) at both ends cannot be normally closed, and the on-board electrical equipment cannot be powered. Normal power supply, even if you change to Tc2 car at this time, you can't activate the train normally

Embodiment Construction

[0018] The present invention will be further described in detail below with reference to the accompanying drawings.

[0019] Newly designed a train wake-up control circuit in the present invention image 3 Indicated. The process of activating the train of this wake-up control circuit is: close two-end control circuit breaker TC1 CB1 / 2 and TC2 CB1 / 2, the driver press the wake button (TC1 WUPB) in the TC1 car, the local train wakes relay (TC1 WUDYR) ) The power is applied and the contact is maintained through the own contact, and then the local train wakes the relay (TC1 WUDYR) contact is turned on to wake up the train line and the TC1 vehicle and TC2 trains are powered by the contactor (TC1 / 2 TSK). At both ends prepare the bus line line to power, start to power the car electrical equipment, and complete the train activation. Specific procedures Figure 4 Indicated.

Abstract

The invention discloses a wake-up logic control circuit, which belongs to the technical field of subway vehicle wake-up control circuits. The control circuit includes the first control circuit breaker of the Tc1 car, the second control circuit breaker of the Tc1 car, the first control circuit breaker of the Tc2 car, the second control circuit breaker of the Tc2 car, the Tc1 car diode, the Tc2 car diode, the Tc1 car Wake-up button, Tc2 car wake-up button, Tc1 car wake-up relay, Tc2 car wake-up relay, Tc1 car power supply contactor and Tc2 car power supply contactor, Tc1 car and Tc2 car circuit are arranged symmetrically. The circuit of the invention greatly improves the anti-risk capability of the train. If the train wake-up relay of the Tc1 car has a short-circuit fault, the wake-up train line cannot be powered, and the driver can switch the terminal to the Tc2 car to activate the train normally, ensuring that the train can wake up normally.

Description

Technical field [0001] The present invention relates to a wake-up logic control circuit, which belongs to the technical field of subway vehicles wake-up control circuitry. Background technique [0002] At present, the basic logic of the wake-up control loop of the subway vehicle is: the driver is pressing the wake button, awakening the train line, and the second-ends are awakening the relay to complete the train. [0003] Wake-up control is mainly to wake up the train from sleep, and start to power the car electrical equipment, which is the most basic prerequisite for the train to run. [0004] Currently, the wake-up logic of the subway vehicle is like figure 1 Indicated. Contact the two-end driver's room control circuit breaker TC1 CB1 / 2 and TC2 CB1 / 2, the driver is pressed by the TC1 car wake-up button, the wakes the train line immediately, at this time, TC1 cars and TC2 cars are awakening relay (TC1 / 2 wudyr) Get electricity and maintain the electricity status through its...
