[0104] In order to make the objects, technical solutions and advantages of the present application clearer, the technical solutions in the present application will be described clearly and completely below with reference to the drawings in the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0105] Figure 1 is one of flowcharts of a train turnaround method provided by the present application, as shown in the figure, the method can include the following steps: Figure 1

[0106] Step 110, converting a logical section where a train is turned around into at least one group of logical section sequences; each group of logical section sequences is any one of a partial route and a logical route;

[0107] Step 120, performing resource locking judgment on each group of logical section sequences;

[0108] Step 130, in the case that it is determined that each group of logical section sequences is in a resource locking state, sending indication information to the train, the indication information being used to instruct the train to turn around through a logical section;

[0109] Wherein, the logical section is determined based on a destination where the train is turned around and a current position of the train;

[0110] The partial route is a route with a terminal signal machine as a terminal point;

[0111] The logical route is a route without a terminal signal machine as a terminal point.

[0112] It should be noted that the execution subject of the above train turnaround method can be a trackside device, such as an ATS (Automatic Train Supervision), an OC (Object Controller), etc.

[0113] In step 110, in the process of train operation, if the train encounters an emergency in front, such as a major safety hazard of waterlogging, landslide, etc., then the train can be executed for a turnaround operation at an arbitrary position.

[0114] ​Specifically, after determining the destination where the train needs to be turned back, the ATS can send a turn-back instruction to an IVOC (Intelligent Vehicle On-Board Controller) of the train, and the IVOC controls the train to brake after receiving the turn-back instruction. After the train is stopped, the ATS determines a logical section for the train to turn back based on the destination where the train needs to be turned back and the current position of the train, and sends the logical section information to the OC.

[0115] As shown in Figure 2 , according to the turn-back direction of the train, the logical sections can include three logical section sequences of 1G, 3G and 5G in turn, and each logical section sequence can further include a plurality of sub-sequences, for example, the logical section sequence 5G can include logical section sub-sequences 5G-A, 5G-B and 5G-C.

[0116] It can be understood that the logical section sequence can correspond to an actual route.

[0117] It should be noted that in the embodiments of the present application, the OC is specifically a TIOC (TCT Intelligent Object Controller). Of course, the train turn-back method of the present application can also be used for other types or manufacturers of OC, and the present application does not specifically limit this.

[0118] After receiving the logical section information sent by the ATS, the TIOC searches for signal machines according to the direction in which the train needs to be turned back, and converts the logical section into at least one group of logical section sequences according to the search result.

[0119] Specifically, the TIOC can convert the logical section into a plurality of groups of logical section sequences according to the search result of the signal machines, and each group of logical section sequences can correspond to any one of a partial route or a logical route.

[0120] Among them, the partial route is a route with a terminal signal machine as a terminal, and the logical route is a route without a terminal signal machine as a terminal.

[0121] It can be understood that the signal machine is a key component of the rail transit signal system, and is used to command the safe operation of the train. The signal machine only allows the train to issue a signal allowing the train to proceed when the track section in front of the train is empty, the turnout position is correct, the signal machine is open, the hostile route is locked, and the like.

[0122] Compared with a route without a signal machine, a route with a signal machine has a higher degree of protection for the safe travel of the train, and the configuration of the route is usually more complex. For example, a route with a signal machine usually has more turnouts, the route is occupied for a long time, passes / near a platform, and the like.

[0123] Therefore, the present application converts the logical section into a partial route and a logical route by considering the terminal signal, and judges the resource locking state of the partial route and the logical route respectively, which on the one hand can fully consider the influence of the signal on the safety of train turnaround, and on the other hand can also make targeted judgments on different configurations of the route, thereby improving the safety and efficiency of train turnaround.

[0124] It should be noted that when the logical section only includes one logical section sequence, the TIOC can directly convert the logical section sequence into a partial route or a logical route according to whether the route corresponding to the logical section sequence takes the terminal signal as the terminal.

[0125] When the logical section includes multiple logical section sequences, the TIOC will split the logical section into multiple groups according to the situation of the terminal signal, and convert each group of logical section sequences into a partial route or a logical route according to the splitting result.

[0126] As shown in Figure 2 , due to the existence of signal X1, the TIOC can split the logical section into two groups of logical section sequences: the first group: 1G, the second group: 3G+5G.

[0127] Among them, the first group of logical section sequences is a partial route because the terminal signal X1 is the terminal. The second group of logical section sequences is a logical route because it does not contain a terminal signal as the terminal.

[0128] As shown in Figure 3 , since there is no terminal signal in the logical section 1G+3G+5G, the TIOC can split the logical section into two groups of logical section sequences: the first group: 1G, the second group: 3G+5G. Both of these two groups of logical section sequences are logical routes because they do not contain a terminal signal as the terminal.

[0129] As shown in Figure 4 , due to the existence of signals X1 and X2, the TIOC can split the logical section into two groups of logical section sequences: the first group: 1G, the second group: 3G+5G.

[0130] Among them, the first group of logical section sequences is a partial route because the terminal signal X1 is the terminal. The second group of logical section sequences is also a partial route because the terminal signal X2 is the terminal.

[0131] It should be noted that in addition to considering the terminal signal, the TIOC can also consider other factors according to actual needs when splitting the logical section. For example, the splitting can be performed according to the actual length of the route:

[0132] 1. The actual length of the route corresponding to each group of logical section sequences is consistent, as shown in Figures 2 to 4 .

[0133] 2. The actual length of the route corresponding to each group of logical section sequences does not exceed a length threshold, such as 1 km, 2 km, etc.

[0134] The splitting can also be performed according to the number of logical section sequences:

[0135] 1. Each logical section sequence is split into a partial route / logical route, as shown in Figure 5 and Figure 6 .

[0136] 2. The number of logical section sequences corresponding to each group of logical section sequences does not exceed a number threshold, such as 1, 2, 3, etc.

[0137] Of course, the TIOC can also split the logical section according to the busy degree of the corresponding route, the number / type of trackside equipment contained in the logical section sequence, etc., and the present application does not make specific limitations in this regard.

[0138] In step 120, the TIOC performs resource lock state judgment on each group of logical section sequences based on the result of converting the logical section in step 110.

[0139] Specifically, the TIOC performs resource lock state judgment on the partial route and the logical route respectively using different indicators. The resource lock state refers to a state in which resources required for train turnaround are locked. When the partial route or the logical route is in the resource lock state, the train can pass through the route for turnaround.

[0140] In step 130, when the TIOC determines that each group of logical section sequences is in the resource lock state, the TIOC sends indication information to the train to indicate that the train passes through the logical section for turnaround.

[0141] Specifically, the TIOC can send the indication information to the IVOC of the train, which carries specific information of the logical section and information that each group of logical section sequences is in the resource lock state.

[0142] After receiving the indication information, the IVOC controls the train to complete the end change operation and drives based on the resources locked by the logical section to complete the turnaround operation.

[0143] The train turnaround method provided by the application can realize quick and accurate judgment of resources required for train turnaround, and further realize train turnaround at any position.

[0144] In one embodiment, when the TIOC performs resource locking judgment on each group of logical section sequences, different judgment standards are adopted by the TIOC to perform resource locking judgment on the partial route or the logical route due to different specific conditions of the partial route or the logical route.

[0145] Specifically, for the partial route, there are idle state, selected state, resource locking state and waiting unlocking state.

[0146] When the partial route meets the following first condition, the TIOC determines that the partial route is converted from the idle state to the selected state. If the partial route does not meet any of the first conditions, the TIOC determines that the partial route is still in the idle state.

[0147] The first condition includes:

[0148] All logical section sequences of the partial route are correct in checking interlocking conditions;

[0149] All physical sections associated with the logical section sequences of the partial route are not locked;

[0150] All logical section sequences of the partial route are not jump locked;

[0151] All logical section sequences of the partial route are not locked by an enemy route;

[0152] The inner turnout in the partial route is not locked and not guided by the total lock;

[0153] The protection turnout associated with all logical section sequences of the partial route is not locked and not guided by the total lock;

[0154] The side protection condition of all logical section sequences of the partial route is met;

[0155] The inner turnout of all logical section sequences of the partial route is correct in position or incorrect in position but can be operated;

[0156] The protection turnout associated with all logical section sequences of the partial route is correct in position or incorrect in position but can be operated;

[0157] The floodgate interlocking condition is met;

[0158] The connecting line turnout interlocking condition is met.

[0159] When the TIOC determines that the partial route is in the selected state, and all switches within the partial route and the protection switches associated with the partial route are driven to the desired position of the partial route, the TIOC determines whether the partial route meets the following first target conditions. If yes, the TIOC determines that the partial route is converted from the selected state to the resource locking state. If the partial route does not meet any of the first target conditions, the TIOC determines that the partial route is converted from the selected state to the idle state.

[0160] The first target conditions include:

[0161] The inspection interlocking condition of all the logical section sequences of the partial route is correct;

[0162] The physical section associated with all the logical section sequences of the partial route is not blocked;

[0163] All the logical section sequences of the partial route are not jump locked;

[0164] All the logical section sequences of the partial route are not locked by the hostile route;

[0165] The switch within the partial route is not blocked and not guided by the total lock;

[0166] The protection switch associated with all the logical section sequences of the partial route is not blocked and not guided by the total lock;

[0167] The side protection condition of all the logical section sequences of the partial route is met;

[0168] The flood gate interlocking condition is met;

[0169] The connection line switch interlocking condition is met;

[0170] The intrusion condition of all the logical section sequences of the partial route is met;

[0171] The switch position within all the logical section sequences of the partial route is correct;

[0172] The position of the protection switch associated with all the logical section sequences of the partial route is correct.

[0173] It can be understood that when the partial route is in the resource locking state, the TIOC allocates the information that the partial route is in the resource locking state and the corresponding logical section resource to the train, and after the train completes the turnaround, the partial route is converted from the resource locking state to the waiting unlocking state.

[0174] When the partial route is in the waiting-unlock state, it releases resources as the train travels, or three-point checks, sequentially unlocks the logical section sequence until all logical section sequences are unlocked, and the partial route is then in the idle state. If the partial route fails to sequentially unlock as the train travels, a field worker needs to manually confirm that the train has exited the partial route, and the dispatch worker issues a section fault unlock to sequentially unlock all logical section sequences in the partial route.

[0175] Specifically, for a logical route, there are an idle state, a selection state, a resource locking state, an open state, and a waiting-unlock state.

[0176] When the logical route meets the following second condition, the TIOC determines that the logical route is in the idle state to the selection state. If the logical route does not meet any of the second conditions, the TIOC determines that the logical route is still in the idle state.

[0177] The second condition includes:

[0178] All logical section sequences of the logical route are checked for correct interlocking conditions;

[0179] All physical sections associated with the logical route are not locked;

[0180] All logical section sequences of the logical route are not locked by the route;

[0181] All logical section sequences of the logical route are not locked by the logical route, or are locked by the logical route and the locking directions are consistent;

[0182] All logical section sequences of the logical route are not locked by the jump;

[0183] Switches in the logical route are not locked;

[0184] The protection switch associated with the logical route is not locked;

[0185] The side protection condition of the logical route is met;

[0186] The switch position of the logical route is correct, or the switch position is incorrect but can be operated;

[0187] The protection switch position of the logical route is correct or incorrect but can be operated;

[0188] The other position section of the switch is not locked;

[0189] The logical section associated with the switch and not in the route and not associated with the switch is not locked.

[0190] When the TIOC determines that the logical route is in the selected state and all switches within the logical route and the protection switches associated with the logical route are driven to the desired position of the logical route, the TIOC determines whether the logical route meets the following second target conditions, and if so, the TIOC determines that the logical route is converted from the selected state to the resource locking state. If the resource route does not meet any of the second target conditions, the TIOC determines that the logical route is converted from the selected state to the idle state.

[0191] The second target conditions include:

[0192] All logical section sequences of the logical route are checked against interlocking conditions correctly;

[0193] All physical sections associated with the logical route are not blocked;

[0194] All logical section sequences of the logical route are not locked by a route;

[0195] All logical section sequences of the logical route are not locked by the logical route, or are locked by the logical route and the locking direction is consistent;

[0196] All logical section sequences of the logical route are not locked by a jump;

[0197] Switches within the logical route are not blocked;

[0198] Protection switches associated with the logical route are not blocked;

[0199] The side protection condition of the logical route is met;

[0200] The switch position of the logical route is correct;

[0201] The protection switch position of the logical route is correct;

[0202] The other position section of the switch of the logical route is not locked;

[0203] The non-route and non-switch associated logical section of the physical section associated with the switch of the logical route is not locked;

[0204] The intrusion condition of the logical route is met;

[0205] The associated floodgate of the logical route is not closed.

[0206] When the TIOC determines that the logical route is in the resource locking state, and the logical route includes a home signal and the home signal is restored to normal, the TIOC determines whether the logical route meets the following third target conditions, and if so, the TIOC determines that the logical route is converted from the resource locking state to the open state. If the logical route has no home signal, after the train completes the turnaround, the TIOC determines that the logical route is converted from the resource locking state to the waiting unlocking state.

[0207] The third target condition includes:

[0208] The supervision level of the logical route is not point;

[0209] The section sequence in the logical route is not blocked;

[0210] The section sequence in the logical route is completely blocked by the logical route;

[0211] The first section sequence of the logical route is not blocked by the route, and the section sequence in the logical route is not blocked by the route exception;

[0212] The logical route limit condition check is passed;

[0213] The switch of the logical route is not blocked;

[0214] The protection switch of the logical route is not blocked;

[0223] The reversing train does not cross the signal;

[0224] The associated protection switch of the logical route is protected and blocked;

[0225] The starting signal has no closing drive.

[0226] After the logical route is in an open state, the train can enter the logical route, and at this time, the TIOC can cooperate with the on-board system to complete the requirement of arriving at the specified destination. During this period, the TIOC continuously checks the above third target condition; if any of the third target conditions is not met, the TIOC will close the starting signal of the logical route, and the train that has not entered the logical route is prohibited from entering.

[0227] The logical route is in an open state, waiting for the reversing train to complete the crossing of the signal, and the logical route is converted to a waiting unlocking state.

[0228] When the logical route is in the waiting unlocking state, the resource is released along with the train running, or three-point checking, and the logical section sequences are unlocked in turn until all the logical section sequences are unlocked, and then the logical route is converted to the idle state. If the logical route fails to unlock in turn along with the train running, the on-site manual confirmation that the train has left the logical route is needed, and the section fault unlocking is issued by the dispatch manual to unlock all the logical section sequences in the logical route in turn.

[0229] The train turnaround method provided by the application can quickly and accurately determine that the partial route and the logical route are in the resource locking state by using different judgment conditions to determine the state of the partial route and the logical route, so as to realize the turnaround of the train at any position.

[0230] Figure 7 is the second flowchart of the train turnaround method provided by the application, as shown in Figure 7 The method can include the following steps:

[0231] Step 710, receiving the indication information sent by the trackside device;

[0232] Step 720, turning back through the logical section based on the indication information;

[0233] The indication information is generated under the condition that the logical section is converted into at least one group of logical section sequences and each group of logical section sequences is in the resource locking state;

[0234] The logical section is determined based on the destination of the train for turning back and the current position of the train;

[0235] Each group of logical section sequences is any one of the partial route and the logical route;

[0236] The partial route is a route with a terminal signal machine as a terminal;

[0237] The logical route is a route without a terminal signal machine as a terminal.

[0238] It should be noted that the execution subject of the above train turnaround method can be a train, and specifically can be various control systems in the train, such as IVOC, etc.

[0239] During the train operation, if the train encounters an emergency in front, such as waterlogging, landslide and other major safety hazards, the train can perform the turnaround operation at any position.

[0240] Specifically, after determining the destination where the train needs to be turned back, the ATS can send a turn-back instruction to the IVOC of the train, and the IVOC controls the train to brake after receiving the turn-back instruction. After the train is stopped, the ATS determines a logical section for the train to turn back based on the destination where the train needs to be turned back and the current position of the train, and sends the logical section information to the OC.

[0241] As shown in Figure 2 According to the direction in which the train needs to be turned back, the logical sections can sequentially include three logical section sequences of 1G, 3G and 5G, and each logical section sequence can further include a plurality of sub-sequences, for example, the logical section sequence 5G can include logical section sub-sequences 5G-A, 5G-B and 5G-C.

[0242] It can be understood that the logical section sequence can correspond to an actual route.

[0243] It should be noted that in the embodiments of the present application, the OC is specifically a TIOC (TCT Intelligent Object Controller). Of course, the train turn-back method of the present application can also be used for other types or manufacturers of OC, and the present application does not specifically limit this.

[0244] After receiving the logical section information sent by the ATS, the TIOC searches for signal machines according to the direction in which the train needs to be turned back, and converts the logical section into at least one logical section sequence according to the search result.

[0245] Specifically, the TIOC can convert the logical section into a plurality of logical section sequences according to the search result of the signal machine, and each logical section sequence can correspond to any one of a partial route or a logical route.

[0246] The partial route is a route with a terminal signal machine as a terminal, and the logical route is a route without a terminal signal machine as a terminal.

[0247] It can be understood that the signal machine is a key component of the rail transit signal system and is used to command the safe operation of the train. The signal machine only allows the train to issue a signal allowing the train to proceed when the track section in front of the train is empty, the turnout position is correct, the signal machine is open, the hostile route is locked, and the like.

[0248] Compared with a route without a signal machine, a route with a signal machine has a higher degree of protection for the safe travel of the train, and the configuration of the route is usually more complex. For example, a route with a signal machine usually has more turnouts, the route is occupied for a long time, passes / near a platform, and the like.

[0249] Therefore, the application converts the logical section into a partial route and a logical route by considering the terminal signal, and judges the resource locking state of the partial route and the logical route respectively, so that the safety of train turnaround can be improved.

[0250] It should be noted that when the logical section only includes one logical section sequence, the TIOC can directly convert the logical section sequence into a partial route or a logical route according to whether the route corresponding to the logical section sequence takes the terminal signal as the terminal.

[0251] When the logical section includes multiple logical section sequences, the TIOC will split the logical section into multiple groups according to the terminal signal, and convert the logical section sequences of each group into a partial route or a logical route according to the splitting result.

[0252] As shown in Figure 2 , the TIOC can split the logical section into two groups of logical section sequences: the first group: 1G, and the second group: 3G+5G, due to the existence of signal X1.

[0253] Among them, the first group of logical section sequences is a partial route because the terminal signal X1 is the terminal. The second group of logical section sequences is a logical route because it does not contain a terminal signal as the terminal.

[0254] As shown in Figure 3 , the TIOC can split the logical section into two groups of logical section sequences: the first group: 1G, and the second group: 3G+5G, because there is no terminal signal in the logical section 1G+3G+5G. The two groups of logical section sequences are both logical routes because they do not contain a terminal signal as the terminal.

[0255] As shown in Figure 4 , the TIOC can split the logical section into two groups of logical section sequences: the first group: 1G, and the second group: 3G+5G, due to the existence of signals X1 and X2.

[0256] Among them, the first group of logical section sequences is a partial route because the terminal signal X1 is the terminal. The second group of logical section sequences is also a partial route because the terminal signal X2 is the terminal.

[0257] It should be noted that in addition to considering the terminal signal, the TIOC can also consider other factors according to actual needs when splitting the logical section. For example, the splitting can be performed according to the actual length of the route:

[0258] 1. The actual length of the route corresponding to each group of logical section sequences is consistent, as shown in Figures 2 to 4

[0259] 2. The actual length of the route corresponding to each group of logical section sequences does not exceed a length threshold, for example, 1 km, 2 km, etc.

[0260] The splitting can also be performed according to the number of logical section sequences:

[0261] 1. Each logical section sequence is split into a partial route / logical route, as shown in Figure 5 and Figure 6

[0262] 2. The number of logical section sequences corresponding to each group of logical section sequences does not exceed a number threshold, for example, 1, 2, 3, etc.

[0263] Of course, the TIOC can also split the logical section according to the busy degree of the corresponding route, the number / type of trackside equipment contained in the logical section sequence, etc., and the present application does not make specific limitations in this regard.

[0264] Based on the result of the conversion of the logical section, the TIOC will respectively determine the resource locking state of each group of logical section sequences.

[0265] Specifically, the TIOC will use different indicators to respectively determine the resource locking state of the partial route and the logical route. The resource locking state refers to the state in which the resources required for train turnaround are locked. When the partial route or the logical route is in the resource locking state, the train can pass through the route for turnaround.

[0266] In step 710, in the case where the TIOC determines that each group of logical section sequences is in the resource locking state, the TIOC will send indication information to the IVOC to indicate that the train passes through the logical section for turnaround.

[0267] The indication information carries specific information of the logical section and information that each group of logical section sequences is in the resource locking state.

[0268] After receiving the indication information, the IVOC will control the train to pass through the logical section for turnaround based on the indication information in step 720.

[0269] Specifically, after receiving the indication information, the IVOC will control the train to complete the end change operation and run based on the resources locked by the logical section to complete the turnaround operation.
