In the above-mentioned prior art, the on-vehicle control device determines the current position of the vehicle and the permissible traveling speed, and the information signal from the ground computer (the position sent from each vehicle). Information and the point status of the station, etc.) are used to determine the safety speed limit points, etc. that will prevent a preceding vehicle from colliding.

At this time, the on-vehicle controller stores track data relating to track gradients and speed limits, and vehicle data such as vehicle brake performance, and is provided from the ground. A continuous permissible speed curve is calculated based on the safety speed limit point, and the vehicle runs at or below that speed until a new speed limit point is received. In addition, the inter-vehicle distance from the preceding vehicle ahead is detected by a detector installed between the ground and the vehicle, and the allowable speed etc. is calculated and obtained. Consideration has not been given to the operation method that takes into account the congestion status of multiple vehicle groups, and there is a safety issue when implementing high-density operation.

An object of the present invention is to improve the operation efficiency of at least two rail cars traveling in the same direction on the same track between stations provided in a circulation line.

[0008]

In order to achieve the above object, two or more vehicles traveling in the same direction on the same track between stations in a circulation route detect the distance between the front and rear vehicles themselves. In addition to having a detector, it also has a control device that takes in the output signal of the detector and calculates the security speed, and a communication device that transmits the information signal of the control device to the ground computer, and the station computer from the information signal to the ground signal from the ground signal. After calculating the vehicle congestion degree of the vehicle, transmitting the calculation result to the control device of each vehicle and determining the target value of each security speed, the vehicle controls the speed by detecting the traveling position and traveling speed. It was done like this.

[0009]

With the inter-vehicle distance detectors of the vehicles themselves provided on the front surface of the leading vehicle and the rear surface of the trailing vehicle, the detected signals in the front and rear are transmitted to the ground computer via the communication device as operation information, Sequentially calculate the congestion degree of multiple vehicles located between stations, transmit the congestion degree signal to each vehicle, and determine the vehicle congestion degree coefficient if the distance between the front and rear vehicles becomes smaller than the specified value. In consideration of this, by adjusting the deceleration value of the target safety speed variably and setting their travel patterns, high-density operation of multiple vehicles located between stations within the loop line will be performed. You can drive safely.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described below with reference to FIGS.

First, the configuration of a railroad vehicle located between stations within a loop line to which the present invention is applied and the configuration of a control device on the vehicle will be described with reference to FIGS.

In FIGS. 2 and 3, reference numeral 1 is a loop line, and by transmitting an operation command from the ground computer 4 to the on-board antenna 6 via the ground antenna 5, the loop line 1 has a loop loop. At each station 2, the operation operation from the start of each vehicle 3 to the stop is performed. Each vehicle 3 runs on the same track in clockwise and counterclockwise directions, and consists of cases where each station 2 is stopped at each station 2 or is operated at a speed controlled between stations 2. There is. In this example, the configurations of the vehicle 3 stopped at the station 2 and the vehicle 3 operating between the stations 2 with two cars or with three cars are shown.

The operation configuration when each vehicle runs at the security speed will be described with reference to FIGS. 3 and 4. The ground computer 4 sends a radio signal from the ground antenna 5 to the onboard antenna 6 via the ground communication device 7a, and is installed on the vehicle 3 via the onboard communication device 7b connected to the onboard antenna 6. The on-board control device 8 that is present transmits and receives information signals such as the degree of congestion of each vehicle 3 located between the stations 2. The on-vehicle control device 8 of the vehicle 3 inputs the front inter-vehicle distance lf detected by the front distance detector 9, the rear inter-vehicle distance lb detected by the rear distance detector 10, and the speed signal from the vehicle speed detector 11. Then, the control signal combined with the information signal from the ground computer 4 is sent to the vehicle traveling drive device 12 to make the traveling speed variable and perform the operation operation such as departure from the station 2 or stop at the station 2. Although the front distance detector 9 and the rear distance detector 10 are not shown in the drawing, the reflection time is obtained from the reflected light rays by emitting a wide laser light ray and the like, and the inter-vehicle distance is determined by the product of the speed of the vehicle 3 and the reflection time. calculate.

In FIG. 3, the vehicle 3 traveling at the speed v2 in the center has the inter-vehicle distance lf with the vehicle 3 at the front velocity v1, and the inter-vehicle distance lb with the vehicle 3 at the rear velocity v3. is doing. Therefore, in order for the vehicle 3 traveling at the speed v2 to collide with the vehicle at the speed v1, the vehicle-to-vehicle distance lf is the prescribed vehicle-to-vehicle distance la, that is, the deceleration β of the vehicle 3 at the speed v2 is calculated by Equation 1. It should be below the value.

[0015]

[Equation 1]

However, as shown in FIG. 2, when two or three or more vehicles are located between the stations 2, if the vehicle 3 having the speed v2 can consider only the vehicle 3 having the front speed v1, the rear speed. Similarly, the v3 vehicle 3 also needs to be further decelerated, and the operation efficiency is low when a plurality of vehicles operate between stations, which is not preferable. That is, the plurality of vehicles 3 cannot be operated at high density.

Therefore, when there are two or more vehicles 3 between the stations 2, it is necessary to sequentially measure the vehicle-to-vehicle distances between the respective vehicles 3 and obtain a target security speed at which they do not collide with each other.

That is, the deceleration β of each vehicle 3 is equal to the station 2
By correcting the deceleration β taking the vehicle congestion degree coefficient k into consideration, the effect is produced when the inter-vehicle distance becomes equal to or less than the specified value.

The operation of the present invention having the above-mentioned structure will be described with reference to the operation flow chart of the on-vehicle controller shown in FIG. First, the on-vehicle controller 8 sets an initial value such as a CPU (not shown), confirms that the transmission / reception operation with the ground computer 4 is normal, and then detects the current vehicle speed v2. Based on the information signal from the ground computer 4, the traveling speed v1 of the preceding vehicle 3a ahead and the vehicle congestion degree coefficient k are determined.

As shown in FIG. 5, this vehicle congestion degree coefficient k is k = 1.0 when there is one vehicle 3 between the stations 2 including the vehicle 3 stopped at the station 2, and 2 In both cases,
It is set so that k = 1.2, k = 1.5 in the case of three cars, and k = 2.0 in the case of four cars. Then, after detecting the inter-vehicle distance lf with the preceding vehicle 3a in the front and the inter-vehicle distance lb with the rear vehicle 3c, if the predetermined distance la or more, the same target security speed pattern as in the conventional case is set. Next, in the case of approaching the preceding vehicle 3a in front of the specified distance la or less, that is, when the inter-vehicle distance lb with the rear vehicle 3c is the specified distance la or more, the deceleration β is calculated from the equation 1. On the other hand, if not, the deceleration β obtained from the equation 1 is multiplied by the vehicle congestion degree coefficient k to calculate a value.

After setting the target security speed pattern to which the deceleration β obtained in this way is set, the target safety speed pattern is output to the vehicle travel drive unit 12 for travel control, and a brake operation is performed near the target stop position. Car 3 stops at station 2 by performing. Further, when the inter-vehicle distance lf with the preceding vehicle 3a in front is equal to or greater than the predetermined distance la, but when the inter-vehicle distance lb with the rear vehicle 3c is equal to or less than la, the target security speed (v2).
Target security speed pattern (v2 + △
v2) is set to control traveling.

According to this embodiment, it is possible to safely and efficiently operate a plurality of vehicles running between stations without colliding with each other, so that a high-density operation of a plurality of railway vehicles operating on a circulation route can be performed. There is an effect that can be done.
