DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. Fig.1 (a) is explanatory drawing when traveling control of a train (moving body) is performed using the speed check apparatus which concerns on one Embodiment. The same components as those in FIG. 3A will be described using the same reference numerals.
[0010]
In FIG. 1 (a), P is a speed verification pattern used when the train a traveling on the rail r performs travel control, and the on-board device 1 receives predetermined speed limit information such as a stop limit point from the ground. those that received to generate. In the speed check pattern P shown here, a stop limit point S0 is set at a position that is a predetermined distance away from the starting point Sn from which train A has received predetermined information for generating a new speed check pattern P. It shows the rate Shosa pattern when being.
[0011]
Velocity Shosa pattern P, as in the known velocity Shosa pattern, based on the train characteristics of the brake performance of the train (train A) is set so as to stop at the stop limit point S 0. At a position far away from the stop limit point S0 in the direction opposite to the train travel direction (between travel points Sn to S6 in the example of FIG. 1 (a)), the train travel speed is the maximum allowable in order to increase driving efficiency. The speed is set to be close to the speed (in the example of FIG. 1A, the train speed V6) (refer to the speed check pattern P in FIG. 1A).
[0012]
FIG. 1B shows the speed verification data used when the train A performs speed verification, which is stored in the memory 3 described later of the on-board device 1 . Speed Shosa data, each speed in the case of dividing the allowable maximum speed of the train Lee at predetermined speed (e.g., 2km / h) (for example, V0 to V6) and, corresponding to each speed, the speed Shosa pattern on P Traveling position (for example, S0 to S6). That is, from the memory 3, the train speed as an index, approaching at that speed is configured to be able to determine the position to be acceptable (virtual traveling position). In FIGS. 1 (a) and 1 (b), for the sake of simplicity, the predetermined speed and the traveling position are illustrated in only six stages and six points. Therefore, the speed reduction curve of the speed check pattern P is also shown as a steep slope near the stop limit point, as in the case of FIG.
[0013]
Figure 2 is a block diagram showing a schematic configuration of a vehicle on the device 1 has a control unit 2 which is comprised mainly of CPU. The controller 2 is configured to receive position information and speed information.
[0014]
The controller 2 is configured to detect the actual traveling position and speed of the own train (train A) based on the position information and the speed information. That is, the position information is, for example, Ru obtained from the earth upper child. Then, the controller 2, the reference position obtained from the earth element, the self-train traveling distance calculated from the speed generator which is provided on the axle and the speed information obtained from (not shown) travel time In addition, the current travel position (actual travel position) can be detected.
[0015]
In addition to the speed verification data described above, the memory 3 also stores predetermined data such as a system program for controlling the controller 2, but the contents thereof are omitted because they are not directly related to the description of the present invention. Yes.
[0016]
The speed check using the speed check data stored in the memory 3 is performed as follows. That is, the train (train A) at a constant rate of in speed of the data rate Shosa of the train b is obtained via a tachogenerator (not shown) (FIG. 1 (a), in the example of (b) V6 ~ each time equal to V0), i.e., the virtual travel position shown in velocity Shosa pattern P for each speed index and (S6 ~S0) and the actual traveling position of the train is Shosa. Then, in the Shosa, when the actual traveling position exceeds the virtual travel position, the brake control signals for actuating the service brake or emergency brake Ru is outputted from the controller 2.
[0017]
As described above, in the prior art, the speed check according to the present invention is performed for each of the own trains as compared to the speed check performed by comparing the virtual travel speed at the actual travel position of the own train and the actual travel speed of the own train. Data to be stored in the storage area (data for speed verification) , because it is performed by collating the approach limit position ( position where the approach is allowed) on the speed check pattern P at the stage travel speed with the actual travel position of the own train There is a feature that the amount can be remarkably reduced compared with the conventional one. Accordingly, since the amount of stored data is small, the speed check time can be shortened , and the memory 3 having a small capacity is sufficient.
[0018]
In the above example, the moving body is a train, but other moving bodies may be used.
[0019]
