Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for extracting train trains between trains. 2. Description of the Related Art In a railway, construction, maintenance, and inspection work of facilities along a track such as a track and an overhead line do not hinder the operation of the train and ensure the safety of workers.
It is necessary to check in advance the time period during which the train does not pass through the work section. Conventionally, the extraction of the safe time zone is manually performed by a person having specialized knowledge to check an approximate time when a train enters a work section from a train schedule. [0004] In the conventional method, the extraction of a safe time zone takes a great deal of time in a complicated train schedule due to manual work, and it takes a lot of time to avoid an extraction error. Burden increases. [0005] It is an object of the present invention to provide an extraction processing device which reliably and easily extracts a train operation interval. [0006] In order to solve the above-mentioned problems, the present invention is an apparatus for extracting a time period between train operations when a train is not located in a designated section of a railway, wherein the train is operated. A train storage unit that stores train schedules including each station for each line section and line to be stored, and saves train operating conditions such as the last and first trains, and stores each station and train diagram included in a designated section to extract train intervals. The process of reading out from the diamond storage unit and extracting the time zone in which the train is located from the reference station in the section to the adjacent station and the time zone running between the stations as a bit data string is performed for each station from the reference station to the end of the section. A time extracting unit that extracts a time period that is not included in the result of the logical sum processing of the extracted time periods as a time period for train operation, and a time interval that the time extracting unit extracts is a designated section. And a time storage unit for separately storing and outputting. [0007] A time zone in which a train is located between stations and between stations is automatically extracted from a train schedule or the like, and a time zone not included in the time zone is automatically set as a time zone in which maintenance work or the like can be performed. To extract. [0008] In the extraction of the time zone, a process of individually extracting a reference station and a station adjacent thereto as a bit data string for each station in a designated section, and extracting the next adjacent station using the adjacent station as a reference station is repeated. . The time zone where the train is located and the time zone where it is not are defined as data strings distinguished by logic "1" and "0". Ask for the obi. FIG. 1 is an apparatus configuration diagram of a computer showing an embodiment of the present invention. The train storage unit 1 stores a train schedule for each section of each line.
Various operating conditions of the train, such as starting conditions, branching conditions, and summing conditions, are input. In addition, the branch of the train means that the train
From the station, enter a line that is different from the line
It is to line. Also, the sum of the trains is on the train schedule
Then, even in a separate line, if the actual train runs on the same track,
Or, even if they are not on the same track,
Where there is, the adjacent line is called the sum line section. example
For example, in the example of FIG. 3, the vehicle travels from station E to station A via station B.
Train branches off at station B, turns back at station A, and returns to station B.
Furthermore, the train traveling to station E branches at station B. This place
In this case, the area between the stations A and B is the total line section of the station E. The train storage unit 2 stores train schedules which are added to the respective train schedule lines stored in the train storage unit 1, and their attribute inputs, such as train termination conditions, starting conditions, and branching conditions, are stored as attribute inputs. Various operating conditions are input. The interval extracting unit 3 automatically extracts the interval for the section when the interval for creating the train operation interval is specified, and extracts the train schedule including the interval from the diamond storage units 1 and 2 for this extraction. And automatically extract the train operation interval from these train schedules. The display unit 4 displays input / output data necessary for creating the interval extracting unit 3. The interval storage unit 5 stores the data extracted by the interval extracting unit 3 and outputs the interval data of the designated section as a list. FIG. 2 shows a flow chart of the extraction processing of the interval extraction unit 3. Hereinafter, each process will be described in detail. First, a line and a line including a line to be subjected to interval extraction and a line to be added are selected, and an interval extraction interval is input (S1). Stations included in the input interval are extracted and a start point of the interval is extracted. The station is set (S2), and the train schedule including these sections is taken out from the schedule storage units 1 and 2. Next, an appropriate reference station outside the section is selected (S3). It is checked whether the selected reference station is a station included in the section (S4), and if it is included, the train stop time, travel time, entry time, turn-back time,
A bit is set at the branch time or the like, which means the same as running the station (S5). This bit setting is a case where the stations A to D and the stations A and B included in the section are combined with the station E as shown in FIG. A bit "1" is written to each of the stations A to D at the time of each minute. After the bit setting at the reference station is completed, the station adjacent to the reference station is automatically set according to the line (S6), and it is checked whether or not the adjacent station is a station included in the input section (S7). If it is included, a bit indicating that the vehicle is running is set at a stop time or the like (S8), similarly to the process S5. Next, a train common to the reference station and the adjacent station is extracted, and a running bit is set from the train schedule in a running time zone between both stations. For this bit setting, for example, a bit “1” is written in the traveling data (up and down) between the stations A and B in FIG. By the above-described processes S4 to S9, a bit standing indicating that the train is running between the reference station and the adjacent station and between the stations is obtained. Hereinafter, similarly, unless the adjacent station is a station at the end of the section (S10), the adjacent station is set as a reference station (S11).
A bit is set to indicate that the train is running. Then, when the adjacent station is a station at the end of the section, for example, when the station A in FIG. 3 is at the end of the section, the logical sum of the stations included in the designated section and the train running bit between the stations is obtained ( S12). Further, when there is a total line section (S13),
The total line section is set for each line (S14), and the processing from step S2 to step S12 is performed for the total line section. In the example of FIG. 3, the total line section is between the stations A and B, and the time from when the train from the station E is located at the stations A and B for branching and returning, and the time when the train is traveling between the stations A and B, respectively. Make a bit. By the above processing, in processing S12, data in which the time zone during which the train is running is the logical sum of the bit "1" is obtained. The example of FIG. 3 shows the logical OR data while traveling at stations A and B. Then, in the logical sum data, a time zone in which no bit is set is a time interval during which work can be performed. This data is converted into text data by time in minutes (S15), registered and stored in the interval storage unit 5, and taken out as a list according to the work section. As described above, according to the present invention, a time zone in which a train is located between stations and between stations is automatically extracted from a train schedule or the like, and a time zone not included in this time zone is extracted. Since the automatic extraction is performed as a time interval in which maintenance work or the like is possible, conventionally, there is an effect that a manual operation by a person having specialized knowledge is unnecessary and an extraction can be surely performed without an extraction error.
