Description

  The present invention relates to a vehicle traffic control system for operating a vehicle based on a movement blockage method.

  For example, in a vehicle traffic control system for a railway vehicle, a vehicle operation method called a fixed blockage method has been used before. This is a method of allowing only one train to exist in a certain section set on the travel route and prohibiting other trains from entering this section. However, since this fixed blockage method cannot cope with a high density of train intervals, a vehicle operation method called a movement blockage method has recently been adopted (see, for example, Patent Document 1).

  FIG. 11 is an explanatory diagram showing the configuration of a vehicle traffic control system that employs this movement blockage method. In this figure, a central control device CC and roadside control devices SC1, SC2 are connected to a transmission line L, and ground communication devices GTM1, GTM2 having an antenna AT are also connected.

  In addition, vehicles T1 and T2 are traveling on the travel path of the main line SL1. These vehicles T1 and T2 are equipped with on-board controllers TC1 and TC2 and on-board communication devices TTM1 and TTM2, respectively. It is designed to send and receive.

  A side line SL2 is provided on the opposite side of the main line SL1 across the station ST. The side line SL2 is branched from the main line SL1 by branching devices JC1 and JC2 installed at both ends of the station ST. Further, branching devices JC3 to JC6 are installed at locations away from the station ST, and the service line SL3 is branched from the main line SL1 via these branching devices JC3 to JC6.

  The roadside control devices SC1 and SC2 control the branching devices and other devices installed in their own jurisdictions. Here, as indicated by the broken arrows, the roadside control device SC1 has the branching devices JC1 and JC2. The road-side control device SC2 controls the branch devices JC3 to JC6.

  The central control device CC collects various information from the roadside control devices SC1 and SC2 and the on-board communication devices TTM1 and TTM2, and performs comprehensive management and control related to vehicle operation.

  In the example illustrated in FIG. 11, the distance of a predetermined section in the traveling direction from the tail end side with respect to the vehicle T2 is the travel path exclusive right setting section. This travel route exclusive right setting section is a section set so that the vehicle T2 can continue to travel or stop safely, and vehicles other than T2 are prohibited from entering this section.

  In addition, if a branching device is installed in the section for setting the exclusive ownership of the road, this branching device is also prohibited from being “converted / locked” for vehicles other than T2. The state of “lock” is controlled so that the vehicle T2 can travel.

Then, as the vehicle T2 travels in this section in the traveling direction, the setting of the exclusive right of the traveling path on the tail end side of the vehicle T2 is sequentially released. That is, the travel route exclusive right setting section moves in the traveling direction together with the vehicle T2.

  According to the present invention, a configuration having high reliability is not given to all means for realizing the function of the movement blockage method, and a high probability of being directly connected to a personal accident when normal operation is inhibited. Since a highly reliable configuration is given only to a means for realizing an important function, it is possible to suppress the complexity of control logic and the use of expensive parts as much as possible. Therefore, a sufficient cost reduction can be achieved.

  FIG. 1 is a block diagram showing the configuration of the first exemplary embodiment of the present invention. As shown in the figure, the system according to this embodiment includes a vehicle speed / position detection means 1, a vehicle speed / position control means 2, a vehicle tracking means 3, a diamond management / control means 4, a course configuration sequence control means 5, a vehicle presence A presence / absence confirmation unit 6, an exclusive right assignment request unit 7 such as a traveling road, an exclusive right management unit 8, a branching device control unit 9, and an exclusive right cancellation request unit 10 such as a traveling road are provided. In the first embodiment, it is not limited as to which of the means 1 to 10 includes the central control device, the on-board control device, and the roadside control device.

  In the present invention, the function of each means constituting the system is a function that has a high probability of being directly connected to a personal accident when normal operation is inhibited (referred to herein as a vital function). It is divided into functions that are not so (referred to as non-vital functions in the present specification), and a means for realizing the vital functions is given a highly reliable configuration. In the example shown in FIG. 1, means for realizing the vital function are vehicle speed / position detection means 1, vehicle speed / position control means 2, vehicle presence / absence confirmation means 6, exclusive property management means 8 such as a traveling path, branching device control, and the like. The means 9 and the exclusive right cancellation request means 10 such as a traveling road, etc., are constructed in a double structure (they are shown as two of the blocks overlapped). .

  The vehicle speed / position detection means 1 is a means for detecting the speed and position of each vehicle, and is usually mounted on the on-board controller side in a railroad train system (however, a system other than a railroad train, For example, in an unmanned train system, it may be installed on the central controller side or road side controller side). If the normal operation of this means is hindered, there is a high probability that a personal accident such as a collision accident will occur. Therefore, the vital function realizing means has a double structure.

  The vehicle speed / position control means 2 is a means for controlling the speed and position of each vehicle. Like the vehicle speed / position detection means 1, the vehicle speed / position control means 2 is usually mounted on the on-board controller side in the railway train system. It is. Since this means also has a high probability that a personal accident such as a collision will occur if its normal operation is hindered, it has a double structure as a vital function realization means.

  The vehicle tracking means 3 is a means for tracking all the vehicles traveling on the traveling road based on the detection of the vehicle speed / position detecting means 1 and grasping the current position of the vehicle. This means is a non-vital function realization means because even if the normal operation is hindered, a personal injury does not occur immediately.

  The diamond management / control means 4 is a means for managing and controlling the diamond such as correcting the schedule of vehicle operation based on the tracking operation of the vehicle tracking means 3. This means is also classified as a non-vital function realization means because a personal injury does not occur immediately even if the normal operation is hindered.

  The route configuration order control means 5 uses linear information (information such as the gradient / curve of the travel path and the position / type of the branching device) stored in a common database (not shown) and information from the diagram management / control means 4. Based on this, it is a means for determining where and in what order the vehicle travels, and further extracting a travel path and branching device through which the vehicle passes. When the course configuration order control means 5 determines the traveling order, an efficient traveling order is obtained by using prediction by simulation or the like. The course configuration order control means 5 is also classified as a non-vital function realizing means.

  The vehicle presence / absence confirmation means 6 is a means for confirming the presence / absence of all vehicles traveling on the road based on the detection by the vehicle speed / position detection means 1. If the vehicle presence / absence confirmation means 6 has a means for detecting the presence of a train in addition to the vehicle speed / position detection means 1, it is preferable to use detection information based on such means together. This vehicle presence / absence confirmation means 6 is a vital function realization means because when the normal operation is hindered and the presence / absence of the vehicle cannot be confirmed, there is a high probability of being directly connected to a personal accident. If a situation occurs in which the vehicle presence / absence checking means 6 loses sight of the vehicle, it is necessary to stop the vehicle operation by operating an emergency stop device (not shown).

  Based on the information from the course configuration sequence control means 5, the travel path etc. exclusive right assignment request means 7 determines whether the travel road etc. is based on the information that the vehicle presence / absence confirmation means 6 confirms the presence / absence of all vehicles. If it is not owned by another vehicle, it is a means for requesting assignment of the exclusive right. Here, “traveling road etc.” means that a branching device is included in addition to the traveling road. This means is a non-vital function realizing means. This is because even if a request for allocating exclusive rights such as a roadway is not made normally, it does not immediately lead to personal injury.

  The exclusive right management means 8 such as the travel road monitors the exclusive state of the travel road and the branching device, and when there is an assignment request from the exclusive right assignment request means 7 such as the travel road, the vehicle for which the assignment request has been made. On the other hand, the exclusive right such as the driving path is assigned to a section that can be exclusively used, such as not occupied by another vehicle, and the branching device control means 9 is controlled to control the branching device so that the vehicle can travel. It is a means of indicating. In addition, even if it is not exclusively owned by another vehicle, if it is a section that is not continuous (not connected) with the current exclusive section, the exclusive section cannot be assigned.

  The exclusive right management means 8 such as the traveling road, etc., when the exclusive right cancellation requesting means 10 requests the cancellation of the exclusive right such as the traveling road, etc. Release the right. This exclusive right management means 8 such as a traveling road is a vital function realization means.

  The branching device control means 9 is means for controlling the branching device based on an instruction from the exclusive right management means 8 for traveling roads and notifying the exclusive state managing means 8 for the control state. If the control of the branching device is not performed normally, the probability of being directly connected to a personal accident is clearly increased, so this means is a vital function realization means.

  Based on the information from the vehicle speed / position detection means 1 and the course configuration sequence control means 5, the exclusive right cancellation request means 10 for the driving road etc. requests cancellation regarding the exclusive rights such as the driving road set at the point where the vehicle has passed. It is a means to perform. If this cancellation request is not made normally, the operation of other vehicles will be hindered and the possibility of a personal accident occurring will increase, so this means is a vital function realization means.

  Next, the general operation of FIG. 1 will be described based on the flowchart of FIG. First, the vehicle speed / position detecting means 1 detects the vehicle speed and the vehicle position (step 1). The vehicle tracking means 3 performs vehicle tracking based on the detection signal from the vehicle speed / position detection means 1 and grasps the current position. The vehicle presence / absence confirmation unit 6 also confirms the presence / absence of the vehicle based on the detection signal from the vehicle speed / position detection unit 1. The vehicle tracking means 3 and the vehicle presence / absence confirmation means 6 perform such vehicle tracking and vehicle presence / absence confirmation for all the vehicles (step 2).

  The diamond management / control unit 4 manages and controls the vehicle operation diagram based on the tracking result of the vehicle tracking unit 3 (step 3), and further corrects the diamond if necessary.

  The course configuration sequence control means 5 extracts the course configuration of each vehicle, that is, the travel path and branching device through which the vehicle passes based on the schedule managed by the diamond management / control means 4, and sets the travel order of each vehicle. (Step 4).

  An exclusive right assignment requesting means 7 such as a traveling path inputs the course configuration and the traveling order of each vehicle from the course configuration order control means 5 and inputs the confirmation result of the existence of all the vehicles from the vehicle presence / absence confirmation means 6. Then, an exclusive right assignment request for the road and branching device is made to the exclusive right management means 8 such as the road (step 5).

  The exclusive right management means 8 such as the traveling road constantly monitors the exclusive situation of the traveling road and the branch device, and the exclusive right assignment request is assigned to the traveling road and the branch device for a certain vehicle from the exclusive right assignment requesting means 7 such as the road. When the request is received, if it is not exclusively owned by another vehicle, the exclusive right is assigned to the requested vehicle (step 6).

  Then, the exclusive right management means 8 such as the driving path outputs a control command to the branching device control means 9 so that the assigned branching device is “converted / locked” in a direction that matches the traveling of the vehicle. (Step 7). Thereby, the branching device control means 9 controls the branching device, and informs the exclusive right management means 8 such as a traveling path of the control state.

  The vehicle speed / position control means 2 receives a detection signal from the vehicle speed / position detection means 1 and also receives management information from the exclusive right management means 8 such as a traveling road, and from a common database (not shown). Route information and vehicle performance information are entered. Then, the vehicle speed / position control means 2 is linked to the stop target position of the vehicle (for example, the terminal position of the exclusive right setting section such as the traveling road, the direction in which the vehicle can travel in the exclusive right setting section from these signals and information. The front position of the unbranched branching device and the position closest to the vehicle among other positions where safety is not ensured are calculated, and the speed and position of the vehicle are set so that this stop target position is not exceeded. Control is performed (step 8).

  As described above, the configuration of FIG. 1 is not limited as to which of the means 1 to 10 includes the central control device, the on-board control device, and the roadside control device. 2 to 4 to be described later, the vehicle speed / position control means 2 is provided on the on-board control device side. However, a part or all of the function for calculating the target stop position can be separated from the vehicle speed / position control means 2 and provided on the central controller side. For example, the function of comparing the end of the exclusive section and the position of the unopened branching device is shared by the central control device, and the function of determining the final stop target position taking into account the uninterrupted level crossing position etc. A configuration that is shared by the apparatus side is also possible. It is possible to provide all of these stop target position calculation functions on the central controller side, but in this case, the burden on the central controller side increases.

  Now, the exclusive right cancellation requesting means 10 for the road and the like inputs information about the driving situation from the vehicle speed / position detection means 1 and the course configuration sequence control means 5, and the vehicle sets the exclusive right setting section such as the road and the like. After passing, a request for cancellation of the exclusive right of the traveling road is made to the exclusive right management means 8 of the traveling road (step 9).

  The exclusive right management means 8 such as the traveling road cancels the exclusive right such as the traveling road allocated to the vehicle based on the cancellation request (step 10).

  Next, a specific operation of FIG. 1, for example, an operation in the case of assigning exclusive rights such as a road once assigned to a certain vehicle to another vehicle will be described with reference to the explanatory diagram of FIG.

  In FIG. 10, the vehicle T1 traveling on the main line SL1 is in a position in front of the station ST, and the vehicle T2 is stopped on the side line SL2 of the station ST. The vehicle T2 is scheduled to depart after the vehicle T1 passes the station ST. Therefore, at present, the exclusive right M1 such as a traveling road extending in the traveling direction from the tail end side is set for the vehicle T1. The vehicle tracking means 3 receives detection signals from the vehicle speed / position detection means 1 of the vehicles T 1 and T 2, grasps the respective current positions, and outputs the tracking results to the diamond management / control means 4.

  However, since the operation of the vehicle T1 is remarkably delayed, the diamond management / control unit 4 corrects the diagram so that the vehicle T2 is started first before passing the vehicle T1, and the course configuration sequence control unit 5 It is assumed that a travel path and a branching device to be exclusively used for the departure of the vehicle T2 are extracted based on the diagram.

  The travel route exclusive right assignment requesting means 7 requests the travel road exclusive right management means 8 to assign the travel road exclusive power M2 to the vehicle T2 based on the extraction result. Upon receiving this request, the runway exclusive right management means 8 checks the exclusive state of the current runway and the branching device, sets the exclusive right M1 setting section that has already been set, and sets the exclusive right M2 to be set in the future. Extract the overlapping part with the section. Then, an inquiry is made to the vehicle speed / position control means 2 of the vehicle T1 for which the exclusive right M1 is set as to whether or not the vehicle can be safely stopped at the front side of the overlapping portion, that is, the front side of the branching device JC2. In response to this inquiry, the vehicle T1 side determines whether or not it can be safely stopped at a position in front of the branching device JC2 by a stop propriety determination unit (not shown).

  When the vehicle T1 returns a response indicating that the vehicle cannot be stopped at the position before the branching device JC2, the exclusive right management means 8 such as the traveling road rejects the allocation request for the exclusive right M2 from the exclusive right allocation requesting means 7 such as the road. Then, the exclusive right M1 is held in the vehicle T1, and the vehicle T1 is waited for to pass.

  On the other hand, when an answer indicating that the vehicle T1 can be stopped safely at the position before the branching device JC2 is returned from the vehicle T1 (the vehicle T1 sends the answer to the exclusive right management means 8 such as the road and the exclusive right cancellation request means 10 such as the road) Since the request for canceling the exclusive right M1 is sent from the exclusive right cancellation requesting means 10 to the traveling road etc., the exclusive right management means 8 Permit the request to cancel exclusive right M1. Then, the exclusive right management means 8 such as the traveling road should permit the allocation request of the exclusive right M2 to the vehicle T2 from the exclusive right allocation requesting means 7 such as the traveling road and control the branching device JC2 so that the vehicle T2 can pass. To the branching device control means 9. As a result, the exclusive right M2 of the vehicle T2 is set on the side line SL2 and the main line SL1, and the vehicle T2 departs from the station ST and can travel safely.

  In the configuration of FIG. 1 described above, a configuration having high reliability is not given to all means for realizing the function of the movement blocking method, but only for the means for realizing the vital function, that is, normal. A highly reliable configuration is given only to a means that realizes an important function that has a high probability of being directly connected to a human accident when the operation is hindered, so that the control logic is complicated and expensive parts are used. Can be suppressed as much as possible. Therefore, a sufficient cost reduction can be achieved. On the other hand, in the prior art, since all the means 1 to 10 shown in FIG. 1 are provided with a highly reliable configuration, it has not been possible to achieve a sufficient cost reduction.

  In the configuration example of FIG. 1, high reliability is given to the means for realizing the vital function by adopting a duplex configuration, but it is possible to have a multiplexed configuration of triple or more. It is. Further, high reliability may be ensured by using an expensive part having an error rate of a predetermined level or less (for example, a level of 10 to the sixth power or less).

  FIG. 2 is a block diagram showing the configuration of the second exemplary embodiment of the present invention. This embodiment limits the control apparatus to which each means in FIG. 1 belongs. That is, the central control unit CC includes the vehicle tracking means 3, the schedule management / control means 4, the route configuration order control means 5, the vehicle presence / absence confirmation means 6, the exclusive ownership assignment requesting means 7 such as the traveling road, and the exclusive rights management such as the traveling road.

In this embodiment, since it is not necessary for the central control device CC to perform computations regarding the assignment of exclusive rights such as traveling roads, the burden on the central control device CC can be reduced by that much, and compared to the third embodiment. The operational efficiency of the central controller CC can be further increased.

  FIG. 5 is a block diagram showing the configuration of the fifth exemplary embodiment of the present invention. This embodiment divides the road exclusive right allocation requesting means 7 in the first embodiment of FIG. 1 into a road exclusive right allocation requesting means 7A and a branching apparatus exclusive right allocation requesting means 7B, and the road exclusive The right management means 8 is divided into a travel path exclusive right management means 8A and a branch device exclusive right management means 8B, and the range of functions shared by each means is clearly divided. Note that the exclusive right cancellation requesting means 10 such as the traveling road is not divided into a function relating to the traveling road and a function relating to the branching device, and is left as it is. This is because, unlike allocation, there is little merit in dividing in the case of cancellation. Since the operation of the fifth embodiment can be easily inferred from the operation of the first embodiment described above, the description thereof is omitted.

  FIG. 6 is a block diagram showing the configuration of the sixth embodiment of the present invention. This embodiment limits the control device to which each means in FIG. 5 belongs.
