The circuit principle is as follows:
when the bicycle is organized into a group, the K1 and K2 coils are in an inactivated state, the states of C1-C11 are kept unchanged, and the circuit breakers CB1 and CB2 are in a closed conducting state. The current flows through CB1 → C1 → C7 → S → C4 → TCMS, and the train control management system monitors the relevant state. Meanwhile, TCMS monitors and collects the states of the K1 and K2 relay coils and the contacts, and can send out an alarm when the states are inconsistent. When any functional state Sn is in fault and the switch thereof is disconnected, the TCMS can execute a corresponding protection strategy; if the TCMS detects the signal, the S1-Sn are normal, the vehicle can be started normally, and the TCMS can execute a corresponding normal strategy.
The application is applicable to marshalling vehicles, namely, after front and rear vehicles are marshalled and connected through the electric hook connectors, corresponding pins of the front and rear vehicles are connected together, the whole circuit can be automatically connected into a circuit, the S1-Sn of each vehicle is connected with the S1-Sn of the other vehicle in series, therefore, the TCMS can automatically detect signals of all vehicles after the S1-Sn of all vehicles are connected in series after the marshalling, when a corresponding state switch in any S1-SN of any vehicle is disconnected, the TCMS module detects a corresponding disconnection signal, can judge that a certain function in the vehicle is completed, and can execute a corresponding protection strategy, such as forbidding vehicle starting and the like.
As shown in fig. 2, a schematic diagram of the connection between two trains (Train 1 and Train 2) is shown, after the two trains are connected, a new Train formation is formed, the ECP2 of Train1 is automatically connected with the ECP1 of Train2, the ECP is a mirror image when being connected, and P11/P12, P21/P22, P31/P32, P41/P42 and P51/P52 are 5 sets of mirrored contacts.
The circuit principle is as follows:
after the two-bank connection is completed, K2 of Train1 is activated, and the current path is CB2 (Train 1) → Pin31 (Train 1) of ECP2 → Pin32 (Train 2) of ECP1 → Pin41 (Train 2) of ECP1 → Pin42 (Train 1) → K2 (Train 1) of ECP2, and the normally open and normally closed state of the contacts (C6 to C9) changes as shown in fig. 2.
C1 of Train2 is in an open circuit state, the circuit cannot be continuously supplied with power, and the current path of the newly formed Train state detection circuit is as follows: CB1 (Train 1) → C8 (Train 1) → C2 (Train 2) → C7 (Train 2) → S: (Train 2) → C3 (Train 2) → C9 (Train 1) → S: (Train 1) → C4 (Train 1) → TCMS, and Train state detection of the two-Train formation is achieved.
The train state detection principle of more than two marshalling is consistent with that of two marshalling, and the two marshalling trains are just trains which are connected in front of and behind the multi-marshalling train, and the principle is the same.
The circuit of the invention mainly comprises a breaker, a trolley hook and a relay. The circuit breaker is a necessary protection device of a vehicle circuit, and the trolley coupler head is a basic configuration for flexibly grouping a motorcade train, so that the invention greatly simplifies the circuit device.
The circuit design fully utilizes the characteristic of flexible marshalling train linkage, namely the two-position end of the front train and the one-position end of the rear train are linked, and the contacts of the K1 and K2 relays are combined and applied based on the characteristic, so that the flexible marshalling train state detection function is realized.
The TCMS also monitors and compares the power supply of the front end of the relay coil with the normally open contact of the relay, and once the two signals are inconsistent, the TCMS indicates the fault of the relay or the line and timely informs related operation or maintenance personnel to carry out troubleshooting and repairing.
The circuit in fig. 1 can be used as a fixed structure for detecting the flexible train formation state, in a specific application, the state of the unit only needs to be corresponding to S1 to Sn in a dashed frame, and n represents the number of functional units to be detected on a minimum train formation. For example, a train with the minimum marshalling train has 4 bogies, all parking brake release states of the train need to be detected, at this time, n is 4, S1 corresponds to the parking brake release state of the bogie No. 1, S2 corresponds to the parking brake release state of the bogie No. 2, and so on, the circuits of S1 to S4 are connected, and the TCMS can obtain whether all parking brakes of the train are released or not. The corresponding common functions are: all doors closed, all doors locked, all parking brake applied, all service brake released, etc.
The method is suitable for multi-marshalling trains, and can realize the series connection of S1-Sn of each train once corresponding pins of the train are connected together after the train is connected, so that all state signal switches in the marshalling train are connected in series, the series detection of all signals is realized, a protection strategy can be started when any state switch is disconnected, and the function of detecting the state switch is realized. The concrete advantages include: the method has the advantages that other unnecessary control logics in the circuit are removed, only one relay and one breaker are used at a single end of the train, the cost of components is reduced, and the probability of failure of the train circuit caused by component faults is reduced.
Secondly, through the differentiated circuit design of the two ends of the train, when a plurality of trains are in a marshalling and linked operation, if the principle that the two-position end of the front train is connected with the one-position end of the rear train is not followed, the circuit cannot be conducted, the train state is in an open circuit, the trains cannot move, and the safety guarantee is increased.
In addition, the circuit is not only suitable for the operation requirement of flexibly grouping the motorcade, but also suitable for the rescue working condition.
Finally, the circuit controls the local relay by utilizing the hook coupling state of the local terminal, does not depend on mechanical devices such as a limit switch and the like, and is high in reliability. Meanwhile, under the rescue working condition, if the circuit of the rescue vehicle breaks down, the circuit cannot be conducted after the electric hook head is cut off, and the diffusion of the breakdown of the rescue vehicle is avoided.
It is clear that the specific implementation of the invention is not restricted to the above-described modes, and that various insubstantial modifications of the inventive concept and solution are within the scope of protection of the invention.
