Management module 222 is adopted in drive, is adopted equipment to all drives in our station and is managed.
Data map translation module 223, and converting state for the acquisition information to trackside equipment indicates information, will be received
Interlocking host data is translated, control information is converted to corresponding drive command.
Device control module 224, controls trackside drive according to drive command and adopts execution equipment 7, sets to control and execute trackside
It is standby.
Plug-in unit 25 is adopted in drive, adopts the data-interface of equipment and hard for object control unit OCU1 corresponding drive for providing trackside equipment
Part interface.
Object control unit (OCU) does not set electric equipment maintenance machine, and the equipment state record of management is united by affiliated interlocking host
One management.
In some embodiments, management module and the available full electricity of device control module are adopted in the drive of object control unit (OCU)
The form of sub- control module is constituted.
In the embodiment shown in Figure 2, the equipment that object control unit OCU1 ..., object control unit OCUn are managed
State recording is managed collectively by interlocking host 21.
The data configuration in host is interlocked, region is carried out using all fronts equipment uniform data of ATP system in CBTC system
Access way control and management in lock range.It interlocks host and realizes the unification numbered with ATP system all fronts trackside signalling arrangement ID
It uses, interlocking host is all made of the code bit format based on above-mentioned data to locking sheet, and route is carried out within the scope of regional interlock
Control and management.Access by interlocking host to trackside equipment, uses all fronts equipment of the ATP system in field of track traffic
Uniform data, change it is original interlocking and other subsystems between need the mode of data conversion, thus realize interlock system and
The integration of zone controller.
The ID based on driving and adopt equipment of object control unit (OCU) still in a traditional way is numbered to trackside signalling arrangement
It accesses.
Each object control unit (OCU) is completed all fronts trackside signalling arrangement ID number and is adopted with drive by the differentiation of station number
Mapping translation between device id number.Completely each station passes through the differentiation of station number, object control list using unique mark station number

Cluster interlocking part function is shared, solves the problems, such as the bandwidth and off-capacity of interlocking host.
Fig. 3 discloses the typical logic control stream of Distributed Area computer interlock system according to an embodiment of the invention
Cheng Tu.In embodiment as shown in Figure 3,
It interlocks host and sends control command, the control command uses all fronts uniform data form of ATP system；
Object control unit (OCU) receive include control command information correspondence message, to being assisted safely used by message
View is verified, and is passed through if do not verified, is abandoned the message；
If verification passes through, the corresponding code bit of the message is converted into our station drive and adopts equipment by object control unit (OCU)
The corresponding data format of ID number carries out logic control inspection, communication check or the monitoring of other failure safes；
If logic control inspection is not over terminating process and result is fed back to interlocking host；
If communication check and the monitoring of other failure safes are not over cutting off output and swing to safe state, the safety
When state refers to the state, all input acquisitions are invalid, stop externally all outputs:
If logic control inspection and communication check and the monitoring of other failure safes all pass through, object control unit
(OCU) drive control trackside equipment executes or keeps output, and trackside equipment executes corresponding actions and to object control unit (OCU)
Output state back production table；
If trackside equipment output state back production table not over detection, is more than after a certain period of time, to cut off to trackside equipment
Output, process terminates.
