Embodiment Construction
[0014] Such as figure 2 As shown, the present invention includes 2 local activation relays, 2 train activation relays, 2 self-locking knobs and 2 driver key limit switches.
[0015] When the driver at one end operates the driver key, the driver key limit switch is closed, and the relay KM1 (the first relay) will be energized to activate the local end. As KM1 is energized, its contacts 23 and 24 will be closed, resulting in two train units The train activation relay KM2 (the second relay) is energized at the same time. 1. When the KM2 at one end is energized, its contacts 21 and 22 will be disconnected, and the local activation relay KM1 at one end will self-hold by relying on the closed contacts 13 and 14 of its own. 2. When the KM2 at the second end is energized, its contacts 21 and 22 will also be disconnected. At this time, if the driver operates the driver key at the second end, the 21 and 22 contacts of the relay KM2 will be disconnected due to the train activation. Activ...

The invention discloses a driver's cab activation interlocking circuit and method, and a train. The interlocking circuit comprises two interlocking units. Each interlocking unit comprises a first relay and a second relay. One ends of coils of the first relays are grounded, and the other ends of the coils of the first relays are connected with first contacts of the first relays and contacts of thesecond relays; the first contacts of the first relays and the contacts of the second relays are connected in parallel and then connected to a driver key of one driver's cab; one ends of coils of the second relays are grounded, and the other ends of the coils of the second relays are connected with second contacts of the first relays; the second contacts of the first relays and the driver key are connected to a power supply; connections are arranged between the second contacts of the first relays and the coils of the second relays; and connections of the two interlocking units are connected. According to the invention, the logic interlocking function of an activation terminal is fulfilled from the hard line of the train, and the conflict judgment problem of train activation is solved from the hard line.
Description
Technical field [0001] The invention relates to the field of rail transit, in particular to a driver's cab activation interlock circuit, method and train. Background technique [0002] Such as figure 1 As shown, under the current technology, after the driver's key is operated at either end of the driver’s cab at both ends of the train, the relay KM1 at this end is energized to represent the activation of the local end. At the same time, the information is collected into the IO module, and the IO module sends the information to TCMS. TCMS will consider that the terminal is active and the train is active. At this time, if the driver's key is also operated on the other end, TCMS will consider that the activation of the train operated by this end is invalid, and will report the failure of simultaneous activation of both ends on the train control display. [0003] The train activation logic relies on the TCMS network. If the TCMS network is faulty or unreliable, the train cannot be act...
