Abstract

PROBLEM TO BE SOLVED: To solve such a problem that motorman's human error cannot be prevented, for instance, when arriving the stop station, the human error to mispass without stopping the station cannot be prevented, though the works of motormen and station employees can be decreased by computerizing an effective tablet between specific stations for achievement of blocking between the stations.SOLUTION: An onboard control device that outputs the brake so that a train 102 cannot start when the tablet (1) 101 is not received is mounted on the train 102, and when transmitting the tablet (1) 101 to the train, the ground equipment 103a matches the distance (1) effective for the tablet (1) 101 and performs transmission. When receiving the tablet (1) 101, the onboard control device receives the distance (1) effective for the tablet (1) 101, and outputs the brake so that the train 102 may run the received distance, and prevents running outside the range not being permitted.

Description

  The present invention relates to a train control method and a train control system that allow a train existing between stations to travel safely without causing a train to collide in a line section having a train interval of about one train.

  In order to avoid the collision of trains and to ensure the safety of train traveling, it is necessary to detect the position of the train and control each train so that the trains do not collide with each other. Therefore, a device for detecting the position of the train and a device for controlling the train are required. In a line section where the number of trains to be operated is small, the initial cost and the maintenance cost of the above-mentioned device become a problem.

  Therefore, in line districts with a small number of trains, there is no problem in operation even if the position detection accuracy of the train is rough, and because there are many single-line sections, it is based on the concept of one block between stations where only one train exists between one station. In many cases, safety is ensured.

  As a method for realizing one block between stations, methods such as a stuff block type and a tablet block type have been used for a long time. These systems use a permit for traveling between stations, called slips. Both the staff closing type and tablet closing type are configured so that there is only one ticket between each station at the same time. By allowing only trains that have a ticket to travel between stations, one station can be closed. Realized.

  For example, as shown in Patent Document 1, a system that digitizes a slip has been devised. Create a unique ticket between each station as electronic data. When a train departs, a vote is sent wirelessly to the train from the ground device installed at the departure station, and after transmission, the ground device at both the departure station and the station to which the train goes is locked. The vote will not be sent until it is canceled.

  When the train departs and arrives at the station, it is sent to the ground device of the station where the ticket arrived, and the vote is confirmed by the ground device. If it matches, both the station where the train departed and the station where the train arrived Unlock the ground device and send the vote again to the train.

  Thus, by locking and canceling the transmission of the ticket, the train that travels with the ticket between stations is limited to one train, and one blockade between stations is realized to ensure safety.

  For example, as shown in Patent Document 2, it is known to perform stop control of a train when traveling an effective distance length included in a train control message.

  The staff closure type and tablet closure type using slips ensure safety by operating rules and cannot prevent human error. For example, even if a train driver with a ticket passes without stopping at the station, there is no way to stop the train.

  Similarly, human error of the driver cannot be prevented when the vote is digitized. For example, in the case of the above-mentioned Patent Document 1, if the driver overlooks the work of transmitting an electronic ticket at the arrival station of the train, there is a risk that the train will pass without stopping at the station where it should arrive.

  In addition, the “train stop control” shown in the above cited document 2 is a function that is not used on the upper side of the vehicle in the ATS-P system that transmits the control information in the form of a telegram to the on-board device of the train from the ground using a transponder. In the case of an emergency in which ground information from the power ground unit cannot be received, stop control is performed, and human error of the driver is not prevented.

  The present invention can reduce the work of the driver and station staff by digitizing the effective vote only between specific stations to realize one blockade between stations, but human error of the driver cannot be prevented. For example, an object of the present invention is to solve a problem that a human error that does not stop at a station and erroneously passes when the station arrives cannot be prevented.

  According to the present invention, an electronic vote is defined between stations, a vote is transmitted from a ground device provided at a station to an on-board device provided on a train, and a ticket held by the ground device after transmission is deleted. Further, when the train arrives at the next station, a ticket is transmitted from the on-board device to the ground device, and the ticket held by the on-board device after transmission is deleted. By deleting the slips after sending in this way, there is always only one slip, and no ground device or on-board device has a function to create slips, so that multiple slips are generated. This makes it possible to reliably realize one blockage between stations.

  Further, the on-board control device outputs a brake so that the train cannot depart when it has not received a vote.

  When the ground device transmits a ticket to the train, the ground device transmits the same distance that the ticket is valid. Usually, the distance that the vote is valid is the distance between stations. The on-board control device also receives the distance when receiving the ticket, outputs a brake so as to travel the received distance, and prevents entry into a section where the ticket is not valid.

  By constructing such a signal control system, even if a driver's human error occurs, the train can be stopped within the effective range of the vote, and it is possible to ensure the safety of train travel.

FIG. 1 is a conceptual diagram showing an outline of signal control processing in an embodiment of the present invention. FIG. 2 is a flowchart showing the flow of train processing from departure of a train to arrival at the next station in the embodiment of the present invention.

  In the present invention, the trains existing between the stations have a one-block block between trains, and even if a driver's human error occurs, the trains can travel safely without causing a collision. The purpose of making it happen was realized with a simple system configuration.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 shows a concept of a signal control system in an embodiment of the present invention. In FIG. 1, a plurality of slips (1) 101 indicating permission of traveling between the A station and the B station are shown in FIG. 1 because the processing flow as the entire system is shown. ) Since the information of the ticket (1) 101 is deleted at the place where 101 has been transmitted, there is actually only one, and either the train 102 or the ground device 103a at the A station or the ground device 103b at the B station Yes, there is never more than one at the same time.

  First, the flow of processing when the ground device 103a at the A station has the ticket (1) 101 and the train 102 leaves the A station and heads to the B station will be described.

  The train 102 at the A station transmits a departure permission request for departure to the B station to the ground device 103 a via the station train transmission device 105. The station-to-train transmission device 105 is a device that enables transmission and reception of information between the ground device 103 and the train 102, and only needs to be able to communicate within a limited range of short distances. Various devices such as a transponder, a varistor, and a general-purpose radio can be used. In the present invention, the inter-station transmission apparatus 105 is not specified.

  When the ground device 103a that has received the departure permission request from the train 102 has the ticket (1) 101, the ground device 103a determines the ticket (1) 101 to the distance where the ticket (1) 101 is valid, that is, to the B station. Along with the distance information, the information is transmitted to the train 102 via the station-to-train transmission device 105. After confirming that the train 102 has received, the slip (1) 101 in the ground device 103a is deleted. If the ground device 103a does not have the ticket (1) 101, the ground device 103b is requested of the ground device 103b at station B via the inter-station transmission line 104.

  If the ground device 103b that has received the request has the ticket (1) 101, it transmits the ticket (1) 101 to the ground device 103a via the inter-station transmission line 104 and confirms that the ground device 103a has received it. Thereafter, the slip (1) 101 in the ground device 103b is deleted. Since the inter-station transmission line 104 is used to transmit and receive the slip (1) 101, an existing inter-station transmission line can be used, and it can operate with a small communication capacity. Various transmission lines such as a twisted pair line, an ISDN dedicated line, and Ethernet (registered trademark) are applicable, and the inter-station transmission line 104 is not specified in the present invention.

  The ground device 103a that has received the ticket (1) 101 from the ground device 103b sends the ticket (1) 101 via the inter-train transmission device 105 together with the distance to which the ticket (1) 101 is effective, that is, the distance to the B station. After transmitting to the train 102 and confirming that the train 102 has received, the slip (1) 101 in the ground device 103a is deleted.

  If both the ground device 103a and the ground device 103b do not have the ticket (1) 101, it means that there is a train running with the ticket (1) 101 between the A station and the B station. , The train cannot be started from either the A station or the B station, and the ground device 103 a does not transmit the ticket (1) 101 to the train 102. When the ground device 103a receives the ticket (1) 101 from another train or the ground device 103b, the ground device 103a transmits the ticket (1) 101 to the train 102.

  The train 102 receives the slip (1) 101 from the ground device 103a together with the distance at which the slip (1) 101 is valid. The brake is output so that the vehicle cannot travel until it receives the ticket (1) 101 together with the valid distance of the ticket (1) 101.

  When the ticket (1) 101 is received together with the distance for which the ticket (1) 101 is valid, the brake is released so that the ticket (1) 101 can travel the valid distance. The brake is output so that the designated ticket (1) 101 travels over a valid distance so that the ticket (1) 101 cannot travel outside the valid range.

  The distance can be measured by counting the number of rotations of the wheel, integrating the speed, and the like, but the distance measuring method is not specified in the present invention. In addition, the train 102 displays on the cab whether or not the ticket (1) 101 is held. The display method may be displayed on a display, or a lamp such as an LED may be used, and is not specified in the present invention.

  Further, the train 102 that has received the distance for which the ticket (1) 101 is valid displays the distance for which the ticket (1) 101 is valid on the cab. The display method may be displayed on a display or a meter, and is not specified in the present invention.

  However, there is a possibility that errors may be included in the distance recognition of the train 102, and the distance (1) 101 received together with the ticket (1) 101 from the ground device 103a is longer than the distance for which the ticket (1) 101 is valid. And a case where the vehicle stops at a short distance. Driving long distances can be dangerous because you go too far from the station.

  However, in general, the distance recognition error of the train 102 is proportional to the travel distance, and the error range can be assumed. Therefore, when traveling a long distance, it is possible to assume in advance how much distance and how much the station goes too far. Therefore, for example, when the safety side line 106 is installed at the station and the train 102 goes too far over the station, the length of the safety side line can be set to be greater than or equal to the assumed maximum error.

  Thereby, safety is maintained even if the train 102 goes too far from the station due to an error. On the contrary, when the train 102 stops at a short distance due to an error, the train 102 stops before the station. In this case, the handling (1) 101 is extended by the driver. can do. The extension distance is assumed to be the maximum error.

  In addition, when the train 102 sounds an alarm before the brake is output and the driver determines that the vehicle stops in front of the station due to an error, the driver handles the operation before the brake is output. If this is done and the distance is increased, the train 102 can arrive at the station without stopping in front of the station, and the train operation can be made smooth.

  When the train 102 arrives at the B station, the ticket (1) 101 it has is transmitted to the ground device 103b via the inter-train transmission device 105. After confirming that the ground device 103b has received the ticket (1) 101, the ticket (1) 101 held by the train 102 is deleted.

  The ground device 103b that has received the ticket (1) 101 from the train 102 holds the ticket (1) 101. At this time, the slip (1) 101 is held only by the ground device 103b, and is not held by other ground devices or trains.

  By configuring the signal control system as described above and transmitting the slip (1) 101 from the ground device 103 together with the distance at which the slip is valid, the vehicle travels outside the unpermitted range due to the human error of the driver. This can be prevented.

  FIG. 2 shows the flow of processing from departure of the train 102 to arrival at the next station in this embodiment. In step 201 to step 212 in FIG. 2, the traveling safety of the train 102 is ensured.

Step 201:
The brake is output until the slip (1) 101 is received, and the process proceeds to the next step 202.

Step 202:
A departure permission request for departure from the station is transmitted to the ground device 103, and the process proceeds to the next step 203.

Step 203:
Step 204 is repeated until the slip (1) 101 and the distance at which the slip (1) 101 is valid are received.

Step 204:
As in step 202, a departure permission request for departure from the station is transmitted to the ground device 103.

Step 205:
Since the ticket (1) 101 and the distance for which the ticket (1) 101 is valid have been received, the brake is released and the routine proceeds to step 206.

Step 206:
Step 207 is repeated until the travel distance of the train 102 reaches a distance for which the received vote (1) 101 is valid.

Step 207:
It is checked whether the travel distance of the train 102 has traveled close to the distance for which the received slip (1) 101 is valid. If the vehicle is traveling close, the process proceeds to step 208. If it is not running close to the vehicle, the process proceeds to step 209.

Step 208:
The brake is output so that the train 102 travels a distance where the ticket (1) 101 is valid.

Step 209:
When the train 102 stops in front of the station due to a distance measurement error, it is checked whether the driver has handled the extension of the distance, and if so, the process proceeds to step 210. Step 210:
The distance for which the received slip (1) 101 is valid is extended by an assumed maximum error.

Step 211:
The slip (1) 101 is transmitted to the ground device 103 of the station that has arrived. When the train 102 goes too far from the station due to a distance measurement error, it is necessary to move the train 102 to a range where communication with the ground device 103 is possible. However, the method is determined by the operator and is not specified in the present invention.

Step 212:
Step 213 is repeated until it can be confirmed that the ground device 103 has received the slip. If reception is confirmed, the process proceeds to step 214.

Step 213:
As in step 211, the slip (1) 101 is transmitted to the ground device 103 of the station that has arrived.

Step 214:
After confirming that the ground device 103 of the station that has arrived has received the ticket (1) 101, the ticket (1) 101 held by the train 102 is deleted.

  By implementing the processing of the train 102 as described above, the train can travel only in a range where the ticket (1) 101 is valid when it has the ticket (1) 101, and the train traveling safety is ensured. Is secured.

  As described above, the effective distance of the slip (1) 101 may be the distance between the stations. However, if the safety side line 106 cannot be installed due to terrain or the like, the maximum distance assumed from the distance between the stations is assumed. A value obtained by subtracting the error may be used.

  By setting in this way, even when the error becomes the maximum, the train will arrive at the station without going too far. If the error is not maximized, the train stops before the station, ensuring the safety of train travel.

  Or you may set the distance which the ticket (1) 101 is effective to the distance which added the maximum error to the distance between stations so that the handling of a driver may not occur. By setting in this way, the safety side line 106 needs to be lengthened, but the train 102 does not stop in front of the station, and the handling of the driver does not occur.
