Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an operation command device that provides guidance for train operation to a train driver.

Saving train power costs has been studied for some time, and has been done by predetermining optimal standard operating procedures and training drivers. However, in reality, it is often not possible to operate according to standard operation due to the number of passengers or changes in the operating schedule, and in such cases, the driver's intuition is relied upon. In order to back up this information, a device has been devised in which a computer is installed on the vehicle, inputting changes in conditions known to the vehicle, determining the optimal driving notch, and instructing the driver how to handle it. For example, it receives the running time to the next station from the train dispatcher or the train operation control device, determines the coasting point for running at that time, and issues a coasting command when the train reaches that point.

In this case, only the travel time to the next station is given, so if you want to perform recovery operation, you have to recover only between that station. However, in reality, it is sufficient to adjust the time to milestone stations such as terminal stations and connecting stations, and in many cases, stations on the way do not matter. In addition, if recovery is completed for only one station section, it is normal for the recovery to occur after traveling at least a few stations.

The problem here is that depending on the section, there are sections with recovery driving capacity and sections without, and it is better to recover in sections with recovery driving capacity as much as possible, and where to perform recovery driving is selected at the driver's discretion. .

When recovery operation is performed, the power consumption for electric vehicles increases rapidly. Therefore, a recovery method is desired that minimizes the increase in power consumption as much as possible. This purpose can be achieved by using gradients.

The object of the present invention is to provide guidance to a driver in search of a driving operation that utilizes the gradient in the recovery section to perform a recovery operation with as little running power consumption as possible.

The present invention will be explained below based on the illustrated embodiments.

FIG. 1 shows a block diagram of one embodiment of the invention. Reference numeral 1 denotes a recovery section determining unit that selects a recovery operation section, and this determining unit 1 selects data from a station information table 2 that stores information between stations,
The actual traveling time is passed to the coasting point determining section 3. The determining section 3 compares the traveling time versus notch-off speed table with the output of the actual speed detecting section 6 obtained by the speed generator 5, and outputs the output when the coasting point is reached.

Next, its effect will be explained. A recovery time 1a for requesting recovery operation at a certain station is input. The recovery time 1a and its station name code signal 1b are input to the determining unit 1, either via an information transmission device from the ground or by the driver operating a button. The recovery section determination unit 1 uses the inter-station information table 2
Reads data from the input station to the next control station.
The inter-station information table 2 stores data as shown in FIG. Reference numeral 11 is a storage unit for the recovery operation remaining power time between the stations, 12 is a storage unit for storing the order of the increase in power consumption when the recovery operation is performed for that section, and 13 is the storage unit for storing the remaining power consumption time for the recovery operation for that section. This is a storage unit for recovery operation time. These data are stored as values calculated in advance using a computer or the like. That is, sections in which recovery operation can be performed by utilizing the slope are ranked high in the storage unit 12 because the increase in power consumption is small.

Now, if you input at S ₁ station, the next control station S ₄
Extract the data up to now. First, extract the minimum station interval S ₂ to _{S 3} for the increase in power consumption from among them, compare the input recovery time 1a and the recovery surplus time m ₂ of this section, and if m ₂ is small, the next Then, m 1 of the section where the power consumption increase is small, that is, the section S ₁ to _{S 2} is added to m ₂ and the sum is compared with the recovery time _1a . m ₁ +
If m ₂ is large, the recovery section is determined to be those two sections, but if it is small, the next section m ₃ is also added and the same process is performed. In this way, the determining unit 1 determines the recovery operation section.

Next, if the actual traveling section is between _S1 and _S2 , t1 of the storage unit ₁₃ that stores the recovery driving time for that section.
is taken out and passed to the coasting point determining section 3. The coasting point determining section 3 reads out the running time versus notch-off speed table 4 and determines the notch-off speed. This table 4 stores the travel time calculated in advance with respect to the notch-off speed using a computer, and is a function as shown in FIG. This is stored for each station. The notch-off speed corresponding to the running time _t1 received from the determining unit 1 is determined from this table and compared with the actual train running speed detecting unit 6. When the train speed reaches this notch-off speed, the coasting point output 3a is output. . This output 3a can be transmitted to the train control device to directly turn off the train, or can be notified to the driver by display or audio output. The case where recovery operation is performed has been described above, but in normal driving, instead of the storage units 12 and 13 in FIG. 2, the function 14 of driving time versus power consumption is stored as shown in FIG.
(Fig. 5), and the travel time between each station can be determined by finding the combination that results in the minimum power consumption from the combinations that satisfy the input driving time.
