All other embodiments, which can be made by those skilled in the art based on the embodiments of the present invention without making any inventive effort, shall fall within the scope of the present invention.
Fig. 1 is a flowchart of a manual unlocking method for a short-circuit according to an embodiment of the present invention, where the method may be performed by a manual unlocking device for a short-circuit, the device may be implemented in hardware and/or software, and the device may be configured in an electronic device with corresponding data processing capability, and the device may be a Ground Control Center (GCC). As shown in fig. 1, the method includes:
s110, acquiring an unlocking request comprising a route to be unlocked from the interlocking device.
The interlocking equipment is a computer interlocking system (CBI) and is responsible for establishing a railway driving core control equipment for driving and entering ways. The computer interlocking system realizes interlocking control among the switches, the annunciators and the track circuits in the station under the operation of a signal operator or a dispatching center (CTC) system, and is essential guarantee equipment for safe and efficient driving of railways. The route is a route determined by a station yard plan, has a specific starting point and an end point, has a definite life cycle, is generally composed of one or a plurality of sections, and is to be unlocked, and the route is in a close locking state or a pre-locking state. The route to be unlocked in the invention can only comprise a short route, and can also comprise a long route and a short route.
Specifically, the ground control center receives an unlocking request sent by an interlocking device for controlling whether an access to be unlocked can be unlocked or not, and determines the access to be unlocked corresponding to the unlocking request from information carried by the unlocking request.
S120, determining whether the route to be unlocked is close to the associated train.
The associated trains are trains positioned in an associated area of the current route to be unlocked, wherein the associated area refers to an area close to the route to be unlocked, and the trains positioned in the associated area are associated trains which potentially influence the unlocking of the route to be unlocked.
Specifically, the ground control center determines approaching trains running near the route to be unlocked, determines whether the approaching trains enter an associated area of the route to be unlocked according to the running and position information of the approaching trains, and marks the approaching trains entering the associated area as associated trains. The associated train can be a train which initiates the locking of the route and locks the route to be unlocked, and the train which initiates the locking is used as the associated train to determine that the train can be stopped before entering the route to be unlocked, so that the route to be unlocked is unlocked under the condition that the route to be unlocked is not occupied by the train, and the unlocking safety of the route to be unlocked is effectively ensured. Of course, the associated train may be other trains approaching the route to be unlocked, or both, and the associated trains may be judged and determined according to specific scenes, which will not be described herein.
S130, determining a stop stability message of the associated train under the condition that the associated train approaches.
The parking stability information is two types of information that the associated train can be parked in a safety area or the associated train cannot be parked in the safety area, and the safety area is an area where the train is parked in the area and normal unlocking of a route to be unlocked is not affected.
Specifically, when determining that there is an associated train in the associated area, it is necessary to determine whether the associated train can stop in the safe area. If the associated train can stop in the safety area, the safety of the route to be unlocked is not affected even if the associated train approaches the route to be unlocked. If the associated train cannot be stopped in the safety area, the existence of the associated train can influence the unlocking safety to be unlocked, and at the moment, the locking of the route to be unlocked is continued, and the unlocking operation is not executed on the route to be unlocked.
Optionally, the parking stability information of the associated train is calculated according to the attribute information and the running information of the associated train, and the parking stability information of the associated train is used for representing whether the associated train can be parked in a safety area or not.
The size of the safety area can be determined according to the associated train position and the target signal position. And the target signal machine is determined by the ground control center and then is sent to the associated train.
Specifically, if an associated train exists before the current route to be unlocked, the ground control center sends inquiry information about whether the traffic control equipment on the associated train can stop before the traffic control signal to be unlocked stops, and target traffic control information can be added to the inquiry information. After receiving the information, the train-carried control equipment comprehensively judges according to the train attribute, the current speed, the current running information of the line and the like, and when the associated train ensures that the associated train can stop before the target signal or before the target signal, the information that the train can stop in the safe area is sent to the ground control center, and otherwise, the information that the train cannot stop in the safe area is sent. The parking stability information is calculated through the associated train, so that the parking stability information can be better determined according to the actual working condition of the train, and the situation that the parking stability information is inconsistent with the actual working condition of the train is avoided.
And S140, sending a stop stability message of the associated train to the interlocking equipment, wherein the stop stability message is used for indicating the interlocking equipment to determine an unlocking result of the route to be unlocked according to the stop stability message.
The unlocking result comprises the steps of executing the unlocking of the route to be unlocked or not executing the unlocking of the route to be unlocked.
Specifically, after acquiring the parking stability information of the associated train, the ground control center forwards the parking stability information to the interlocking equipment, and the interlocking equipment determines whether the safety of the current route to be unlocked is enough to execute unlocking of the route to be unlocked according to the train parking stability information, and executes the unlocking result.
According to the embodiment of the invention, the ground control center determines the associated train and acquires the stop stability information of the associated train, and the stop stability information is forwarded to the interlocking equipment for determining the unlocking result of the route to be unlocked, so that the safety of route unlocking is improved by utilizing the stop stability information of the associated train, the determination efficiency of the associated train and the stop stability information is improved, and the route unlocking efficiency is improved.
Optionally, after determining whether the route to be unlocked has an associated train approaching, the method further includes: and sending unassociated train approaching information to the interlocking equipment under the condition that the unassociated train approaches, so as to be used for indicating the interlocking equipment to determine an unlocking result of the route to be unlocked according to the unassociated train approaching information.
Specifically, after the ground control center determines that the route to be unlocked is not close to the associated train, the interlocking device can be notified of the information. Under the condition that the condition allows, the interlocking equipment directly unlocks the route to be unlocked, and the safety is higher when no train approaches, and the unlocking can be immediately performed without delay unlocking, so that the efficiency of route unlocking is further improved.
