Description
Technical field
The present invention relates to field of track traffic, particularly a kind of drivers' cab activation interlock circuit, method and train.
Background technology
As shown in figure 1, under current techniques, after train both ends drivers' cab either end operates driver's key, the end after
Electrical equipment KM1 obtains the electric local terminal that represents and activated, while the information gathering is entered into I/O module, is sent that information to by I/O module
TCMS, TCMS will be considered to end activation and train is active.Now if other end also operates driver's key, then
The train activation that TCMS will be considered to end operation is invalid, and can report both ends in Train Control display screen while activate failure.
Train activation logic depend on TCMS networks, if TCMS network failures or it is unreliable if occur and can not normally swash
The failure that train living or both ends are activated simultaneously.
The content of the invention
The technical problems to be solved by the invention are, in view of the shortcomings of the prior art, providing a kind of drivers' cab activation interlocking electricity
Road and train, the logical interlock function of activated end is realized from train rigid line, even if other end after one end drivers' cab is activated
Driver operation driver key can not also activate train, solve the conflict decision problem of train activation from rigid line.
In order to solve the above technical problems, the technical solution adopted in the present invention is：A kind of drivers' cab activates interlock circuit, bag
Include two interlocking units；The interlocking unit includes the first relay, the second relay；Coil one end of first relay
The first contact, the contact portion of the second relay of ground connection, the other end and the first relay；The first of first relay touches
Point, the contact shunt of the second relay are followed by driver's key of one of drivers' cab；Coil one end of second relay
Ground connection, the second contact of another termination first relay；Second contact of first relay, driver's key connect electricity
Source；Tie point is provided between the contact of first relay second, the second relay coil；The tie point phase of two interlocking units
Connect.
Pressure excision switch is connected between driver's key and the power supply.
Each interlocking unit is installed in a drivers' cab of train.
Corresponding to foregoing circuit, present invention also offers a kind of drivers' cab to activate interlock method, and this method was mainly realized
Cheng Wei：When one end driver operation after driver's key, the first relay obtain it is electric realize that local terminal activates, the second of the first relay touches
Point closure, the second relay of two interlocking units obtain electric, the second relay contact disconnection of one of interlocking unit simultaneously,
First contact closure of the first relay carries out self-sustaining, and the second relay contact of another interlocking unit disconnects, and first
First contact of relay disconnects, so that the activated end of priority service driver's key is after train is activated, it is other end of
Driver can not activate train again.
When operation driver key is completed to break down after train activates when one end, disconnect and force excision switch, so as to disconnect
The power supply circuit of the relay of end first, contact the self-locking logic of the first relay.
Correspondingly, present invention also offers a kind of train, it uses above-mentioned drivers' cab activation interlock circuit.
Compared with prior art, the advantageous effect of present invention is that：Circuit of the present invention is remaining original circuit
On the basis of TCMS monitoring functions, the logical interlock function of activated end is realized from train rigid line, when one end drivers' cab is swashed
Even if other end driver operation driver key can not also activate train after work, the conflict for solving train activation from rigid line judges
Problem, in addition the circuit also there is the activated end activated when one end when can not be disconnected due to fortuitous event local terminal activation promptly to cut
Except logic.
Brief description of the drawings
Fig. 1 is existing interlock circuit schematic diagram；
Fig. 2 is schematic diagram of the embodiment of the present invention.
Embodiment
As shown in Fig. 2 the present invention include 2 local terminals activate relays, 2 trains activation relays, 2 self-locking knobs and
2 driver's key limit switches.
When one end driver operation after driver's key, driver's key limit switch closure, relay KM1（First relay）
Will it is electric realize that local terminal activates, will be closed as KM1 obtains its electric contact 23,24, cause the train activation of two train units after
Electrical equipment KM2（Second relay）Obtain simultaneously electric.1st, when the KM2 of one end obtains electric, its contact 21,22 will be switched off, and the local terminal of one end swashs
Relay KM1 living will carry out self-sustaining by 13,14 contacts itself closed.2nd, when the KM2 at two ends obtains electric, its contact 21,
22 contacts also will be switched off, now if driver operates driver's key at two ends, then can be activated due to train relay KM2 21,
22 contacts have disconnected, and the local terminal at two ends activation relay KM1 will not obtain electric.Priority service is finally realized from hardware circuitry
For the activated end of driver's key after train is activated, other end of driver can not activate the circuit logic of train again.
In addition, local terminal activation is also introduced in circuit forces excision logic, when one end, operation driver key completion train swashs
Broken down after work, for example, key fracture etc., then the other end can not also continue activate train, train rescuing will be caused.To solve
This problem, local terminal activation has been sealed in circuit and has forced excision knob S1, its normally-closed contact 13,14 is sealed in into control circuit,
Its contact 13,14 is disconnected by operating S1 knobs, so as to disconnect local terminal activation relay KM1 power supply circuit to release KM1's
Self-locking logic.
