According to the trackside equipment for computer interlocking management, standardized interlocking logic modules are designed in advance, and the modules can perform corresponding interlocking operation according to the states of the modules, the states of the modules adjacent to the modules, instructions of a vehicle-mounted machine, requirements of an operation line and the like, finally determine the states of the modules and give/release authorized use permission.

A section module: the occupied/cleared status of the sector can be checked, and the locked/unlocked status of the sector is calculated according to the status of the previous sector/semaphore, the usage of the sector and the next sector. The section modules are divided into a turnout-free section module, a track module, a turnout section module, a dead end section module, an interval section module and the like according to the positions, the link relations and the like.

A turnout module: the switch can be operated as expected, the position of the switch can be checked in real time, and the switch is locked to prevent the switch from misoperation during the period of being used.

The intelligent module is a basic interlocking module listed for the purpose of functional description, and it is impossible to elaborate all the modules here, and similar functional modules arranged according to the needs of the trackside equipment are all the protection scope of the present invention.

2) A vehicle-mounted device: the vehicle-mounted machine mainly bears the function of quick unlocking in the invention, so that the operation efficiency is improved. And the vehicle-mounted machine and the operation line manager synchronously operate the plan, request the state of the trackside equipment from the intelligent interlocking module according to the required path, and drive the vehicle-mounted ATP/ATO according to the authorized state of the intelligent interlocking module.

(2) Design of distributed intelligent interlocking module

1) Static design of intelligent interlocking module

Designing a module port:

the intelligent interlocking module is designed into a 1-port module, a 2-port module and a 3-port module … … n;

a. active and dead ports: the active port is a port with a link function and is linked with other active ports during intelligent combination; dead end refers to a port at the boundary of an area, such as the entrance or exit of an interlocking zone.

b. Port design and example:

1, port module: the module is 1 independent device, can be related to other interlocking modules, and affects other signal devices. For example, 1 emergency shutdown button, can be associated to a plurality of annunciator interlocking modules, all associated annunciators of the device must not be opened when the device is actuated;

2, a port module: this type of module has 2 ports, each of which can be linked to the active port of another device. For example, a track segment module has 1 port upstream and 1 port downstream, and the port can be linked to the active port of the next segment and also linked to the active port of the signal machine.

3, a port module: this type of module has 3 ports, each of which can be linked to the active port of another device. For example, a single switch module, 1 active port before, positioning and reversing switch, the port can be linked to the active port of the next segment, signal machine, switch and other modules.

……

An n-port module: as above, i.e. a module with n ports, such as a comb switch module, each port may be linked to the active port of the other module.

Designing module attributes:

each intelligent interlocking module is designed with m attributes for distinguishing the type, function, application environment and the like of equipment. For example, a shunting signal module has the following properties: the display property of blue-white 2 lamp position/red-blue-white 3 lamp position, the uplink/downlink direction property and the like.

2) State machine design of intelligent interlocking module

The intelligent interlocking module is designed with the following p states:

first, a predetermined state:

all trains in the area operate according to a plan, the dispatching can dynamically adjust the train operation lines in real time, and the operation lines give an alarm when in conflict, and manual intervention and adjustment are needed. And after all the modules are released by the previous train operation line, the preset state of the next operation line is entered. For example, a switch module is predetermined as a location state by the next operation line, and when the condition is satisfied (for example, in a release state, the predetermined time is reached, etc.), the module operates the switch to the location state to give the location predetermined state. When the operation plan changes, the module may automatically adjust the predetermined state following the operation line.

Locking state:

and after the intelligent module enters the locking state, the intelligent module sends out use authorization to the corresponding train and the equipment linked with the intelligent module. Even if the schedule is changed from this time, the locked state is not released. A trainline with a conflict with the locked state will not be established. The module will supervise in real time whether the relevant locking conditions are met and enter a fault state immediately once the conditions are not met. For example, a switch module in a predetermined state enters a locked state after a train approaches a dangerous area, and the train will not change position until the train releases or an intelligent module linked with the train releases the switch.

③ in a quasi-locking state:

when the intelligent module is in a locking state, the intelligent module can not guarantee continuous use of the authorized train, and then enters a quasi-locking state. In the quasi-locked state, the device is maintained in the state before locking, but the authorization for using the module is cancelled, including the authorization sent by the intelligent interlocking module to the vehicle-mounted machine and the authorization sent to the intelligent module linked with the self module, such as the display authorization sent to the signal display module, until the quasi-locked state is released. For example, when a switch is in a locked state, the switch is lost, or when a signal is in a locked state, the locked state of a downstream switch is lost, or when equipment is in a locked state, an operation line is manually cancelled, and the like, the equipment in the locked state enters a quasi-locked state, and is maintained in the quasi-locked state unless a safety unlocking command is received or other unlocking conditions are met, such as the end of a safety delay, and when the equipment enters the quasi-locked state, the use authorization of all the equipment is cancelled, including the train use authorization, the use authorization of nodes related to links, such as signal display authorization and the like.

Fourthly, unlocking state:

the unlocked state is a free state of the device, which can be predetermined by the next operating line. There are ways to enter the unlocked state as follows:

a. vehicle-mounted active unlocking: and the vehicle-mounted machine actively releases the intelligent module after the train uses up the equipment.

b. Passive unlocking or logical unlocking: and the upstream equipment is released, the logic of the local area is idle, and the downstream equipment is unlocked after being completely taken over.

c. The initialization state is manually confirmed and then unlocked.

d. And unlocking after the quasi-locking state meets the release condition, for example, the time delay is finished.

For example, after initialization of a turnout is completed, the turnout is manually confirmed to enter an unlocking state; actively releasing after the train leaves the area; release in the upstream section, release after the current section is used and idle, etc.

Reserve state

The reserve state is a standardized state when the module leaves the factory. At the moment, the basic attribute and the basic function of the module are debugged and finished when the module leaves a factory, and the same module is completely the same. For example, a 2 display shunting signal module, a 3 display outbound signal module, a 5 display inbound signal module, a single switch module, a 2 port segment module, a 3 port segment module, a 4 port segment module, etc.

State of activation

The activation state is that the module has already been provided with the network access use condition after being debugged and confirmed on site. At this time, each port of the module establishes a link relation with an adjacent module, the consistency test with the trackside equipment is finished, the version verification is finished, and the on-line permission is obtained. The module in the activated state is periodically confirmed in time and point comparing with the version/authorization security management machine. The module in the activated state can be converted into an unlocked state or a quasi-locked state after manual confirmation or special authorization of the security manager. And the module after being put into use is powered off and restarted, passes the self-checking and obtains the authorization of the safety management machine, and can enter an activation state.

3) The state transition diagram design of the intelligent interlocking module is shown in figure 2.

4) Other designs of intelligent interlocking module

a. Each intelligent module has the functions of optical fiber communication and wireless communication, and an independent IP address is set when the intelligent module leaves a factory and can be modified in a debugging stage.

b. Independent address: when the intelligent interlocking module leaves the factory, each intelligent interlocking module is provided with unique address information, and the information cannot be modified.

A GPS/Beidou/base station type positioning function: each module may send its installed location information to the version/authorization manager or modules linked to it to facilitate automatic generation of the topology.

d. Intelligent interlocking modules within a certain area may automatically negotiate port links that may be modified during the debug phase.

e. When reporting the position of the intelligent interlocking module to the version/authorization management machine, the intelligent interlocking module can synchronously report the port information of each pair of successful links.

f. And the adjacent intelligent interlocking modules can educate the spare parts which are restarted after power failure or newly accessed to the network according to the configuration confirmed by debugging, and the spare parts are verified to pass through the version/authorization management machine after the education is successful or are manually confirmed and accessed to the network after the consistency is verified.

The designed state of the invention is the basic state of the intelligent module, and all similar states derived from the basic state or obtained by simple reasoning are the protection scope of the invention.

It is not possible to exhaustively enumerate all possible scenarios to the present invention, and thus reference to other similar scenarios is intended to be within the scope of the present invention.

The state transition diagram designed by the scheme is designed by way of example, all state transition conditions cannot be elaborated, and relevant conditions added according to scene requirements in actual application are within the protection scope of the invention.
