The present invention relates to a train operation management simulator for training the operation of employees and determining the adequacy of train operation plans.

[Conventional technology]

FIG. 6 is a connection diagram of a conventional simulator shown in, for example, Japanese Patent Laid-Open No. 57-712 and a distributed train operation management device connected to the simulator. The terminal devices 4b to 4n having a processing function and the conventional train operation management simulator 7a are commonly connected to the transmission line 3 via the transmission devices 2a to 2s. The relay interlocking devices 5b-5n and the guidance publicity devices 6b-6n, which are the control target devices, are connected to the terminal devices 4b-4n, and the operation display panel 8 is connected to the central processing unit 1. Here, the central processing unit 1 to the terminal devices 4b to 4n and the operation display device 8 constitute a train operation management device 7b.

Next, the operation will be described. The central processing unit 1 mainly has a man-machine function including management of a train operation plan, man-machine communication with an operator, train operation status display control operation record statistics on an operation display panel, and a function of managing the entire device. Have. The terminal devices 4b to 4n are installed at the respective stations, and the route control of the train is performed based on the train operation plan information of the own station which is transmitted from the central processing unit 1 and the input information from the relay interlocking devices 5b to 5n. Home information Public relations control is performed. No. 7 in the input information from relay interlocking devices 5b-5n
As shown in the route map shown in the figure, information from the track circuit 11 that detects the train position of the train 14 in the platform 10, information from the signal equipment 12 (control state), state from the point 13 (conversion state), etc. There is. The terminal devices 4b to 4n are relay interlocking devices.
Information from 5b-n is taken in, and route control or guidance / publicity control processing is performed based on this information and train operation plan information transmitted from the central processing unit 1, and the resulting control information is relay interlocking device 5b. .About.5n or the guidance and public relations devices 6b to 6n, and also outputs to the central processing unit 1 train tracking information, controlled device failure information, train delay information and the like created by data processing. The central processing unit 1 displays display information, train tracking information and the like on the central operation display panel 8 as a train operation status display.

Here, the train operation management simulator 7a functions as a data generation device that simulates train running and generates display information to be sent from the relay interlocking devices 5b to 5n to the terminal devices 4b to 4n. That is, the train operation management simulator 7a, when given route control information, train departure signal information, etc., obtains simulated display information by imitating the train to run according to these information, and this display information is used for each terminal device 4b. ~ 4n
Data transmission to.

Thus, when the train operation management simulator 7a confirms the function of the entire train operation management device 7b by simulation, it does not actually run the train by controlling the actual relay interlocking devices 5b to 5n, that is, the simulation. Using the information generated by a typical train running, the functional verification of the entire device is performed, and a simulated driving training is provided to the operator.

[Problems to be solved by the invention]

Since the conventional train operation management simulator is configured as described above, it is possible to verify the function of the train operation management device and perform operator training for operation, but it is not possible to simulate fluctuations in the number of passengers at stations and trains. We could not confirm the validity of the operation plan from the viewpoint of passenger transportation, and, for example, when the waiting passengers boarded the train because the waiting passengers at the station increased significantly because the train was significantly delayed. The problem is that the train training and the number of passengers that occur during actual business operation, such as the fact that the time required for trains increases significantly more than usual and the train delays more and more, are related to each other and fluctuate in relation to the feedback system, etc. There was a point.

The present invention has been made to solve the above-mentioned problems, and a control effect with respect to a change in the number of passengers waiting at each station from the viewpoint of passenger transportation of a train that is simulated for functional verification, etc. In addition to being able to quantitatively understand the change in train departure time, the change in train arrival time due to it, the change in the number of passengers waiting at the station due to it, the change in boarding / alighting time due to it, the change in train departure time, etc. , The purpose of the present invention is to obtain a train operation management simulator capable of simulating the train traveling and the feedback system of the fluctuation of the number of passengers which are related to each other that occur during the actual business traveling.

It is composed of

On the other hand, the passenger model simulator 720 is a train passenger number storage unit 721 that stores the number of passengers for each train by dividing it into destination stations, and a station passenger number memory that stores the number of waiting passengers at each station by dividing it by destination station. Based on the time zone characteristics such as the section 722, the number of passengers in the train, the boarding / alighting condition storage section 723 that stores the boarding / alighting conditions such as the number of people who can get on and off per hour, and the early morning off-peak conditions and the rush hours during the commuting hours.

The data to be stored in the train traveling condition storage unit 711, the boarding / alighting condition storage unit 723, and the passenger generation condition storage unit 724 are predetermined by research or prediction.

Next, the operation will be described with reference to the flow chart shown in FIG. FIG. 3A is a flow chart showing the flow of processing of the train travel processing unit 713. First, in step 100, control information is input from the terminal devices 4b to 4n through the transmission device 2s. In step 101, when the passenger model processing unit 725 sends the boarding / alighting end information, the information is input (the decision block is omitted). In step 102, data indicating running conditions such as control information, boarding / alighting completion information, route condition data and train performance characteristic data stored in the train running condition storage unit 711, and further stored in the train running state storage unit 712.

As a result of simulating the running of the train, if the train arrives at the station or immediately after the train leaves the station, in step 103, station arrival information or station departure information is output to the passenger model processing unit 725. Next, in step 104, the display information created in the process of step 102 is output to the terminal devices 4b to 4n through the transmission device 2s, and the process returns to step 100.

The number of waiting passengers at each destination station for each station based on the time zone characteristics stored in the passenger generation condition storage unit 724 at step 200. Based on the data, the number of passengers waiting for boarding at each destination station at that time is calculated and added to the number of passengers waiting for boarding at each station stored in the station passenger number storage unit 722. In step 201, station arrival information or station departure information from the train travel processing unit 713 is input. In step 202, the boarding / alighting condition and the number of trains are stored in the boarding / alighting condition storage unit 723 according to the arrived train, the station name, and the destination station name included in the station arrival information input this time or earlier as the boarding / alighting process. Number of passengers of trains corresponding to station arrival information stored in storage unit 721 and number of station passengers based on the number of waiting passengers at stations corresponding to station arrival information stored in storage unit 722 Then, the data of the number of passengers of the train and the number of passengers waiting to board the station are updated, and the previously input station arrival information corresponding to the train name included in the station departure information is deleted. In step 203, when the train is full due to the boarding / alighting processing performed in step 202, the number of passengers waiting for boarding at the destination station of the station corresponding to the train destination is 0.
When it becomes, the boarding / alighting end information is output to the train traveling processing unit 713. At step 204, the number of passengers waiting to board at each station and the number of passengers at each train are output to the passenger number display 9.
