Description

Technical Field

[0001] The present application relates to the field of computer technology, and in particular to a mobile block control method, device, storage medium and electronic device. Background Art

[0002] At present, during the operation of a train, when the state of the section corresponding to the station entry signal is idle, the radio block center will indicate that the train can enter the section corresponding to the station entry signal. When the minimum front end of the train passes the station entry signal by a certain distance, the radio block center generates the cross-pressure information of the station entry signal according to the position information of the train, and sends the cross-pressure information to the computer interlocking system. After the computer interlocking system receives the cross-pressure information of the train, it controls the station entry signal to close.

[0003] However, in actual railway control, after the radio block center sends the train's cross-pressure information to the computer interlocking system, the train may slip back or retreat due to problems such as the slope of the line near the station entry signal or the train's advanced position. When the train slips back or retreats, the train may exit the section corresponding to the station entry signal, thereby switching the status of the section corresponding to the station entry signal from occupied to idle. If there is a train that has not left the next section of the section corresponding to the station entry signal, the status of the next section is occupied. At this time, the computer interlocking system will misjudge this situation as the train leaving the section corresponding to the station entry signal and entering the next section. At this time, the section corresponding to the station entry signal will be unlocked, that is, the status of the section corresponding to the station entry signal will be set to idle. If there is a turnout in the section corresponding to the station entry signal, then after the section corresponding to the station entry signal is unlocked, the turnout on this section may also be unlocked. Since the train has not entered the next section at this time, the train will continue to run and will still enter the section corresponding to the station entry signal. At this time, the turnout is in an unlocked state, which will cause the risk of the train squeezing the turnout. Summary of the invention

[0043] It should also be understood that the term "if" may be interpreted as "when" or "upon" or "in response to determining" or "in response to detecting." Similarly, the phrase "if it is determined that ..." or "if [a stated condition or event] is detected" may be interpreted as "upon determining that ..." or "in response to determining that ..." or "upon detecting [a stated condition or event]" or "in response to detecting [a stated condition or event]," depending on the context.

[0044] The implementation of the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0045] For example, see Figure 1 , Figure 1 The schematic diagram of a mobile block control system to which the technical solution provided by the present application is applicable is shown. The mobile block control system 100 may include a dispatching device 110, an interlocking device 120 and an on-board device 130. The dispatching device 110, the interlocking device 120 and the on-board device 130 are connected through network communication.

[0046] The dispatching device 110 may be a Radio Block Center (RBC), which is one of the core parts of the train ground equipment. The RBC supervises and controls the operation of trains within its jurisdiction, can communicate with trains running within its jurisdiction, and can also communicate with a computer interlocking system (CI).

[0047] In an embodiment of the present application, the dispatching device 110 is used to communicate with the interlocking device 120 and the on-board device 130. Specifically, the dispatching device 110 receives the position information sent in real time by the on-board device 130. When it is determined based on the position information reported by the train that the train enters the preset range outside the station entry signal, the dispatching device 110 sends a control instruction to the interlocking device 120, and the control instruction is used to control the interlocking device 120 to check the state of the section corresponding to the station entry signal. When the state of the section corresponding to the station entry signal is idle, it indicates that the vehicle access route can be processed. At this time, the train can enter the section corresponding to the station entry signal. When the minimum front end of the train crosses the fuzzy area of ​​the station entry signal, the dispatching device 110 generates the cross-pressure information of the station entry signal based on the position information of the train.

[0048] The interlocking device 120 may be a computer interlocking system. The computer interlocking system refers to a mutual restriction relationship established by technical means between signals, switches and routes in order to ensure the safety of train operation and shunting operations at railway stations.

[0063] The mobile block control device and application scenarios described in the embodiments of the present application are intended to more clearly illustrate the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided in the embodiments of the present application. Ordinary technicians in this field can know that with the evolution of mobile block control devices and the emergence of new business scenarios, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.

[0064] Next, the moving block control method is described in detail with reference to the accompanying drawings. Figure 3 A flow chart of a moving block control method provided in this application. The method is applied to Figure 1 The mobile block control system of the hardware structure shown in the figure specifically includes the following steps:

[0065] Step 310: Obtain train operation information.

[0066] The radio block center is one of the core parts of the train ground equipment. It monitors and controls the operation of trains within its jurisdiction, can communicate with trains running in its jurisdiction, and can also communicate with the computer interlocking system (CI). The computer interlocking system refers to the mutual restriction relationship established by technical means between signal machines, turnouts and routes in order to ensure the safety of railway station operation and shunting operations. The equipment that realizes this relationship is called interlocking equipment.

[0067] During the operation of the train, the train that communicates with the radio block center on the line will report its position information to the radio block center. When the radio block center determines that the train enters the preset range outside the station entry signal according to the position information reported by the train, the radio block center sends a control instruction to the computer interlocking system, which is used to control the computer interlocking system to check the status of the section corresponding to the station entry signal. When the status of the section corresponding to the station entry signal is idle, it indicates that the train can be received. At this time, the train can enter the section corresponding to the station entry signal. When the minimum front end of the train passes the station entry signal by a certain distance, the radio block center generates the cross-pressure information of the station entry signal according to the position information of the train, and sends the cross-pressure information to the computer interlocking system. The cross-pressure information is used as the condition for the computer interlocking to identify the train entering the route. The computer interlocking system controls the opening and closing of the signal according to this command. After the computer interlocking system receives the cross-pressure information of the train, it controls the station entry signal to close.

[0068] However, in actual railway control, after the radio block center sends the train's cross-pressure information to the computer interlocking system, the train may slip back or retreat due to problems such as the slope of the line near the station entry signal or the train's advanced position. When the train slips back or retreats, the train may exit the section corresponding to the station entry signal, thereby switching the status of the section corresponding to the station entry signal from occupied to idle. If there is a train that has not left the next section of the section corresponding to the station entry signal, the status of the next section is occupied. At this time, the computer interlocking system will misjudge this situation as the train leaving the section corresponding to the station entry signal and entering the next section. At this time, the section corresponding to the station entry signal will be unlocked, that is, the status of the section corresponding to the station entry signal will be set to idle. If there is a turnout in the section corresponding to the station entry signal, then after the section corresponding to the station entry signal is unlocked, the turnout on this section may also be unlocked. Since the train has not entered the next section at this time, the train will continue to run and will still enter the section corresponding to the station entry signal. At this time, the turnout is in an unlocked state, which will cause the risk of the train squeezing the turnout.

[0069] Based on the above reasons, the present application sets a fuzzy zone behind the station entry signal to prevent the train's smallest front end from rolling back or retreating after entering the section corresponding to the station entry signal, thereby causing the computer interlocking system to make an incorrect judgment. Based on this, the present application needs to obtain the pre-configured running information of the train when rolling back or retreating in addition to receiving the train's position information at the radio block center.

[0070] In one embodiment, the operation information related to the train rolling back includes: a first rolling back distance, a first slope, a second time, and an emergency braking rate. The first rolling back distance is used to indicate the distance of the train rolling back from the beginning of the train rolling back to the stage when the train triggers the emergency braking. The first slope is used to indicate the maximum slope of the track between the starting point and the end of the section, taking the position of the train length outside the station entry signal as the starting point. The second time is used to indicate the time to apply the emergency brake when the train rolls back. The emergency braking rate is used to indicate the deceleration that can be achieved after the train applies the emergency brake.

[0071] In another embodiment, the operation information related to the train retreat includes: a first retreat distance, a first time, a first slope, a third speed, and a third time. The first retreat distance is used to indicate the distance the train retreats from the beginning of the retreat to the beginning of the traction cutting stage. The first time is used to indicate the time required for the train to cut off the traction. It should be noted that when the train retreats, traction is required to pull the train to retreat, and when the train stops retreating, the traction needs to be cut off. The third speed is used to indicate the speed of the train when it retreats. The third time is used to indicate the time to apply emergency braking after the traction of the train is cut off. When the train retreats, the definition of the first slope is the same as the definition of the first slope when the train rolls back, and will not be repeated here.

[0072] Step 320: Determine the fuzzy area of ​​the section corresponding to the station entry signal relative to the train according to the operation information.

[0073] After the radio block center obtains the running information of the train, the fuzzy area of ​​the section corresponding to the station entry signal relative to the train is determined according to the running information.

[0074] In one embodiment, Figure 4 As shown, the insulating section corresponding to the station entry signal is taken as the starting point of the fuzzy zone. The undivided distance of the train, the maximum reverse slip distance of the train and the maximum retreat distance of the train are determined according to the train operation information. The length of the fuzzy zone is determined according to the undivided distance of the train, the maximum reverse slip distance of the train and the maximum retreat distance of the train, and then the range of the fuzzy zone of the section corresponding to the station entry signal relative to the train is obtained.

[0075] For example, the undivided distance of the train is D1, the maximum reverse distance of the train is D2, and the maximum retreat distance of the train is D3, then the length of the fuzzy zone D=D1+max(D2,D3).

[0076] Since the entire track system network is divided into many block sections at appropriate distances, each block section is separated by track insulation joints to form an independent track circuit, and a signal is installed at the starting point of each block section. This independent track circuit is composed of rail lines and rail insulation. It can automatically and continuously detect whether this section of the line is occupied by a train, and can also control the signal device (signal) to ensure the driving safety of the train.

[0077] When a train enters a block section, the track circuit responds immediately and transmits the information to the signal that a train has already passed through the block section and other trains are prohibited from entering. At this time, the signal at the entrance of the block section immediately displays the information that the train is prohibited from entering (i.e. the signal is closed).

[0078] For the track circuit, the train is considered to have entered the block section only when the axle of the train presses on the track of the track circuit corresponding to the block section, causing the track circuit to short-circuit. However, in order to ensure the safety of train operation, the moment when the smallest front end of the train enters the block section should be considered as the moment when the train enters the block section, rather than the moment when the axle of the train presses on the track of the track circuit corresponding to the block section. Based on this, the present application takes into account the undivided distance when determining the range of the fuzzy zone of the section corresponding to the station entry signal relative to the train, that is, the distance at which the train is not detected by the track circuit corresponding to the section.

[0079] In a railway system, the track circuit often fails to detect the first axle of the train. Therefore, in an embodiment of the present application, the distance between the smallest front end of the train and the second axle of the train is taken as the undivided distance.

[0080] On the one hand, if Figure 5 As shown, when the train rolls backward, the train will first roll backward for a preset distance (i.e., the first rollback distance). After the train rolls backward for the first rollback distance, the train control system will apply emergency braking to stop the train. However, during the emergency braking stage of the train, after the speed of the train reaches a certain level (i.e., reaches the second speed), the emergency braking will no longer be applied to the train. At this time, the train can gradually reduce its speed according to the emergency braking previously applied until the train speed reaches 0, at which time the train stops running.

[0081] Based on this, the maximum reverse roll distance of the present application consists of three parts, namely the first reverse roll distance (the distance the train rolls back from the start of the reverse roll to the stage when the train triggers the emergency braking), the second reverse roll distance (the distance the train rolls back during emergency braking) and the third reverse roll distance (the distance the train rolls back from the stage when the train stops emergency braking to the stage when it stops completely).

[0082] In one embodiment, since the first reverse roll distance of the train is known, the position of the train length outside the station signal is taken as the starting point, and the maximum slope of the track between the starting point and the end of the section is also known, the maximum speed (first speed) that the train can reach in the reverse roll stage can be determined according to the first reverse roll distance and the first slope. In the emergency braking stage, the train performs emergency braking based on the first speed according to the second time and the emergency braking rate. Therefore, the second reverse roll distance of the train can be determined according to the first speed, the second time and the emergency braking rate. In the case of the known speed of the train when the emergency braking starts (i.e., the maximum speed that the train can reach in the reverse roll stage), the first slope and the time when the train applies emergency braking, the speed of the train when the emergency braking stops (the second speed) can be determined according to the first speed, the first slope and the second time. Since after the emergency braking stops, the train decelerates to 0 based on the second speed, the first slope and the emergency braking rate, the third reverse roll distance of the train is determined according to the second speed, the first slope and the emergency braking rate.

[0083] For example, the first reverse rolling distance of the train is D4, the first slope is a, the second time is t2, and the emergency braking rate is a.

[0084] The first speed of the train Where g is the acceleration due to gravity.

[0085] The second reverse slip distance of the train D5 = S1*t2+0.5*a*t2 2 .

[0086] The second speed of the train S2=S1+a*g*t2.

[0087] The third reverse distance of the train

[0088] After calculating the second reverse roll distance D5 and the third reverse roll distance D6 of the train according to the above formula, the maximum reverse roll distance of the train can be obtained, that is, D=D4+D5+D6.

[0089] On the other hand, Figure 6As shown, in some scenarios, the train needs to retreat after the minimum front end passes the signal for a certain distance, for example, the train stops ahead of the signal. In this case, the train begins to retreat under the action of traction. After the train retreats a preset distance (the first retreat distance), the traction will be cut off and emergency braking will be applied to stop the train. Before the train traction is completely cut off, the train will retreat for a distance (the second retreat distance) due to the residual traction. After the train traction is completely cut off, the train starts emergency braking. In the emergency braking stage, the train retreats the third retreat distance according to the preset time and emergency braking rate. Similar to the train rollback, in the emergency braking stage of the train, after the speed of the train reaches a certain level, the emergency braking will no longer be applied to the train. At this time, the train can gradually reduce the speed according to the emergency braking previously applied until the train speed is 0, at which time the train stops running. In this stage, the train retreats the fourth retreat distance.

[0090] Based on this, the maximum retreat distance of the present application consists of four parts: the first retreat distance (the distance the train retreats from the start of retreat to the start of the train cutting off traction phase), the second retreat distance (the distance the train retreats during the train cutting off traction phase), the third retreat distance (the distance the train retreats during the emergency braking phase after the train traction is cut off), and the fourth retreat distance (the distance the train retreats from the emergency braking phase to the complete stop phase).

[0091] In one embodiment, during the traction removal stage of the train, the time required for the train to remove traction (first time) is known, the first slope is known, and the speed of the train when retreating is known, so the second retreat distance can be determined based on the first time, the first slope, and the third speed. On this basis, the maximum speed (fourth speed) that the train can reach during the traction removal period due to the first slope can also be determined. When calculating the retreat distance of the train in the emergency braking stage, the third retreat distance can be determined when the speed of the train when emergency braking starts (fourth speed), the time when the train applies emergency braking after traction removal (third time) and the first slope are known. On this basis, the maximum speed that the train can reach during the emergency braking stage due to the first slope after traction removal can also be obtained. Similar to the train rollback, since after the emergency braking stops, the train decelerates to 0 based on the fifth speed, the first slope, and the emergency braking rate, the fourth retreat distance is determined based on the fifth speed, the emergency braking rate, and the first slope.

[0092] For example, the first retreat distance of the train is D7, the first slope is a, the first time is t1, the third time is t3, the third speed is S3, and the emergency braking rate is a.

[0093] Second retreat distance of the train

[0094] The fourth speed of the train S4=S3+a*g*t1.

[0095] The fifth speed of the train S5=S4+a*g*t3.

[0096] The third retreat distance of the train

[0097] The fourth retreat distance of the train

[0098] After the second retreat distance D8, the third retreat distance D9 and the fourth retreat distance D10 of the train are calculated according to the above formula, the maximum retreat distance of the train can be obtained, that is, D=D7+D8+D9+D10.

[0099] The first slope is 2, the first time is 0.2 seconds, the second time is 0.3 seconds, the third time is 0.1 seconds, and the emergency braking rate is -0.8m / s 2 , the first reverse distance is 2 meters, the first retreat distance is 2 meters, the third speed is 5km / h, and the undivided distance is 5 meters. According to the above train reverse formula, the maximum reverse distance of the train can be calculated to be 7.19 meters, and the maximum retreat distance of the train can be calculated to be 7.72 meters according to the above train retreat formula. In summary, the length of the fuzzy zone of the section corresponding to the station signal relative to the train is D = D1 + max (D2, D3) = 5 + 7.72 = 12.72 meters.

[0100] Step 330: When the smallest front end of the train passes through the fuzzy area, the station entry signal is controlled to be closed.

[0101] When the radio block center finds that the minimum front end of the train has passed the fuzzy area of ​​the section corresponding to the station entry signal relative to the train based on the position information sent by the train in real time, the radio block center sends the cross-pressure information to the computer interlocking system. After receiving the cross-pressure information of the train, the computer interlocking system controls the station entry signal to close.

[0102] In summary, since the present application determines the fuzzy zone of the section corresponding to the station entry signal relative to the train based on the operation information when the train reverses or reverses, when the minimum front end of the train crosses the fuzzy zone, the radio block center sends the cross-pressure information to the computer interlocking system, so that the computer interlocking system controls the closing of the station entry signal based on the cross-pressure information. The fuzzy zone of the present application is determined based on the operation information when the train reverses or reverses, so it can be ensured that when the train reverses or reverses, the section corresponding to the station entry signal is still in a locked state, thereby ensuring the exclusivity of the train entering the section corresponding to the station entry signal, and the section corresponding to the station entry signal will not be unlocked by the interlocking error, thereby ensuring the safety of the train operation.
