The railway disaster linkage safety protection method of the embodiment of the application is based on the following technical conception:
1. the disaster protection system is responsible for monitoring the surrounding environment of the track in real time through a plurality of sensors, and alarms such as side slope falling objects, debris flows, intrusion of foreign matters into the running limit of the train (foreign matter intrusion) and the like. Disaster protection systems are non-secure devices and do not have the conditions to implement a fail-safe policy. The policies implemented by the disaster protection system cannot be left unreported even if they are misreported.
2. The disaster protection system sends alarm information to the driving dispatching command center through an interface between systems and synchronously sends the alarm information to the train operation control system. The interface may be a secure communication interface or a combination of a communication interface and a relay hard-wire interface.
3. And after the traffic dispatching command center receives the alarm of the disaster protection system, the camera closest to the disaster occurrence point in the CCTV system (video monitoring system) is automatically selected to confirm the state of the disaster occurrence point.
4. The train operation control system adopts proper coping strategies such as speed limiting operation, mobile authorization shortening, emergency braking and other measures according to the size and the position of the invasion foreign matters for side slope objects, debris flows, foreign matter invasion and the like.
5. The broadcasting system carries out emergency broadcasting on disasters, reminds passengers to sit stably and hold well, and prevents train from being broken when emergency braking is adopted.
6. The related system is organically linked, and mainly adopts an automatic and manual confirmation mode, so that the quick response of the system is realized, and the key effect of manual work in emergency treatment is realized.
As shown in fig. 1 and 2, a railway disaster linkage safety protection method comprises the following steps: the disaster monitoring system sends disaster information to the dispatching command system and the train control ground equipment in real time, wherein the disaster information comprises position information and range information of the disaster; the dispatching command system generates disaster protection instructions according to the disaster information, confirms the disaster information through the CCTV system and sends disaster protection confirmation instructions to the train control ground equipment according to confirmation results; the train control ground equipment generates new signal authorization and disaster area activation information according to the disaster information and the disaster protection confirmation instruction and sends the new signal authorization and the disaster area activation information to train control vehicle-mounted equipment of all trains in the disaster area; after receiving the new signal authorization and disaster area activation information, the train control vehicle-mounted equipment executes different control strategies according to the disaster position information and the position of the train.
According to the railway disaster linkage safety protection method, the method for controlling the two-way execution of the command of the system by the ground equipment by the train control and dispatch command reduces the response time of the system and increases the accuracy of the system response.
For example, the disaster monitoring system sends disaster information to the dispatching command system and the train control ground equipment in real time as follows: the disaster monitoring system processing unit monitors the surrounding environment of the track in real time through the disaster protection system track side unit, for example, the disaster protection system track side unit comprises a laser radar, a grating optical fiber, a long short focal video camera and the like, when disasters such as falling objects of a slope, mud-rock flow and foreign matter invasion limit occur, the disaster monitoring system processing unit sends position information and range information of the occurrence of the disasters to the dispatching command system and the train control ground equipment in real time, and disaster-free information is sent when no disasters exist, so that the real-time transmission of the information can be ensured.
For example, the dispatch command system generating disaster protection instructions from disaster information includes the steps of: the dispatching command system preprocesses the received disaster position information and the range information, and generates disaster protection instructions according to the relative relation between the disaster occurrence range and the track limit, wherein the disaster protection instructions are specifically as follows:
if the disaster range covers the track limit, generating a disaster activation confirmation instruction, and waiting for the manual confirmation instruction to be sent/cancelled; if the disaster range does not cover the track area but the distance from the track limit is smaller than the set distance, generating a temporary speed limiting instruction of the disaster area, and waiting for the transmission/cancellation of a manual confirmation instruction; if the disaster area does not cover the track area and the distance from the track limit is not smaller than the set distance, generating a disaster area alarm invalidation confirmation instruction transmission/cancellation.
For example, the dispatch command system confirms disaster information through the CCTV system, and sends disaster protection confirmation instructions to the train control ground equipment according to the confirmation result, which comprises the following steps:
s101, a dispatching command system acquires real-time images of disaster areas through a CCTV system, wherein the real-time images are specifically as follows:
after receiving the disaster position information and the range information sent by the disaster monitoring system, the dispatching command system compares the positions of the cameras in the disaster area with the detectable ranges of the cameras (such as the shooting range of a shooting gun and the rotatable range of a shooting holder), and searches all the cameras capable of shooting the disaster area.
And selecting two cameras to shoot the relative distance images between the boundary of the disaster area and the track from different directions, and sending the selected camera ID and shooting range information to a CCTV system.
In the step, the camera capable of carrying out optimal distance and scheduling on the disaster position is determined, the ID of the screened camera and the approximate irradiation angle of the camera are sent to the CCTV system, the disaster protection system can carry out secondary review on disaster alarm, false alarm of the system is eliminated, and the influence on operation efficiency is reduced.
And after receiving the camera ID and the shooting range information, the CCTV system intelligently adjusts the selected camera and shooting parameters, and pushes the real-time image of the disaster area to a display desktop of the dispatching command system.
S102, after the scheduling commander confirms whether the disaster exists for 2 times manually according to the real-time image of the disaster area, confirming the disaster protection instruction. If the disaster protection instructions are not manually confirmed within a certain time (for example, 3 seconds), the scheduling command system defaults to the disaster protection instructions to be confirmed.
S103, after the disaster protection instruction is confirmed, a disaster protection confirmation instruction is sent to the train control ground equipment, wherein the disaster protection confirmation instruction comprises a disaster activation confirmation instruction, a disaster area temporary speed limit instruction or a disaster area alarm invalidation instruction.
For example, the railway disaster linkage safety protection method further comprises the following steps: and the dispatching command system sends a disaster voice broadcasting instruction to the PA system ground equipment according to the disaster information confirmation result. The ground equipment of the PA system controls the PA vehicle-mounted system of the related train to carry out emergency broadcasting according to the disaster voice broadcasting instruction specifically comprises: the ground equipment of the PA system receives the train ID and the voice broadcasting serial number information sent by the dispatching command system and then transmits the train ID and the voice broadcasting serial number information to the related train, and the PA vehicle-mounted system receives the voice broadcasting serial number and then performs emergency broadcasting.
For example, the train control ground device generates new signal authorization and disaster area activation information according to disaster information and disaster protection confirmation instructions, and sends the new signal authorization and disaster area activation information to train control vehicle-mounted devices of all trains in a disaster area, and the train control vehicle-mounted devices comprise the following steps:
s201, the train control ground equipment determines disaster areas and blocking areas according to disaster information specifically comprises the following steps: and adding a protection distance and a speed and distance measurement error in the disaster area, and determining a blocking area, so that the blocking area is larger than the disaster occurrence area.
S202, the train control ground equipment does not send the blocking area as the signal authorization to the train, identifies the signal authorization sent by the managed train, and if the signal authorization contains the blocking area, carries out special calibration on the train which contains the signal authorization of the blocking area, and waits for a disaster protection confirmation instruction of the dispatching command system.
S203, if the train control ground equipment does not receive a disaster area temporary speed limiting or disaster area blocking instruction sent by the dispatching command system within a set time, changing a blocking area from pre-blocking to blocking areas, closing a signal machine of a track section where the blocking areas are located, sending a disaster activation instruction to train control vehicle-mounted equipment of all trains in the blocking areas, and updating signal authorization or sending an emergency braking instruction to the specially calibrated trains.
In this step, the set time may be set as needed, and may be 3s, for example.
S204, processing the train running on the adjacent line, and if the train running is related to the pre-blocked area, if no train running is carried out, sending a temporary speed limiting instruction to the local line area corresponding to the pre-blocked area, wherein the speed limiting value is the allowed speed of the RM mode; if the pre-blocked area has the vehicle running, the principle of processing the adjacent lines is consistent with the processing mode of the disaster occurring line.
And S205, if the train control ground equipment receives the temporary speed limiting command of the disaster area sent by the dispatching command system within the set time, the annunciators of the track sections where the disaster area is positioned maintain the original interlocking relationship, and the temporary speed limiting command of the disaster area is sent to the train control vehicle-mounted equipment of all trains in the disaster area.
In this step, the set time may be set as needed, and may be 3s, for example.
S206, if the train control ground equipment receives the disaster area blocking instruction sent by the dispatching command system within the set time, closing the annunciator of the track section where the disaster area is located, sending disaster activation instructions to train control vehicle-mounted equipment of all trains, and updating signal authorization or sending emergency braking instructions to the trains which are calibrated specifically.
The updating of signal authorization, the sending of temporary speed limiting command in disaster area or the sending of emergency braking command is specifically as follows:
s301, as shown in fig. 3, when the train does not enter the disaster area, the signal authority of the approaching train (e.g., train a in fig. 3) is updated, and the shortened signal authority is transmitted so that the farthest end of the signal authority cannot enter the disaster area. The near line approaches the train (e.g., the train car in fig. 3) to send a temporary speed limit for the disaster area.
S302, as shown in fig. 4, when the train is traveling in a disaster area, an emergency braking command is sent to the train (e.g., train b in fig. 4), so that the damage to the train caused by high-speed operation is reduced. A shortened signaling authorization is sent for an approaching train (e.g., a train car in fig. 4).
S303, as shown in fig. 5, when the train is running in the disaster area, but has passed the disaster area, the control command for the train (e.g., train c in fig. 5) is unchanged. For trains where the front end of the train has passed over the disaster area (e.g., the train blocks of fig. 5), the running state is not changed.
And S304, during the disaster occurrence period, the train control ground equipment always transmits relevant information of the disaster until the repair of the disaster area is completed, and the disaster monitoring system cancels the disaster alarm. Or shielding disaster alarming information in the dispatching command system manually, and performing the train control ground equipment according to a processing strategy of shielding the disaster alarming information manually, such as completely shielding the disaster alarming information, shielding disaster alarming, setting temporary speed limiting in a disaster area and the like.
For example, after the train control vehicle-mounted device receives the new signal authorization and disaster area activation information, different control strategies are executed according to the disaster position information and the position of the train, specifically as follows:
