[First Embodiment]
FIG. 3 shows the configuration of the vehicle congestion transition notification system according to the first embodiment of the present invention.

  The system shown in FIG. 1 includes a plurality of stations 21 to 25, a train operation subsystem 10 including trains 11 and 12, a congestion information processing server 1, a user portable terminal 3, a closed communication network 2, and a public network 4. .

  The train operation subsystem 10 including the stations (a) 21 to (e) 25 and the trains (B) 11 and (A) 12 is, for example, a train system of JR or private railways. The trains 11 and 12 have a congestion sensor (not shown), and the congestion sensor output (numerical data or video data) is transmitted to the congestion information processing server 1 via the closed communication network 2. Here, the congestion sensor (not shown) is a pressure sensor, a camera, or the like provided in each vehicle of the train. The closed communication network 2 is a so-called user-dedicated communication network, and a network configuration with a dedicated line is also conceivable. In addition, a VPN including L2-VPN, L3-VPN, etc. can be considered. However, the present invention is not limited to a specific type of closed communication network. However, the present invention is not limited to a specific type of closed communication network.

  The public network 4 may be an Internet network or a subscription telephone network or a mobile phone network, but the present invention is not limited to a specific public network type.

  The congestion information processing server 1 aggregates the congestion sensor outputs and creates congestion information and congestion transition information. For example, when a user at the station 22 requests congestion information from the mobile information terminal 3 via the public network 4, the congestion information processing server 1 The information processing server 1 transmits congestion information of the train 11 which is the latest train and future vehicle congestion transition information regarding the train 11 to the station 25 as response data to the portable information terminal 3 via the public network 4. The vehicle congestion transition information is for estimating future vehicle congestion transition information of the train 11 from the transition of the congestion degree as the track record of the train 12 that has already passed through the station 22, the station 23, and the station 24.

  FIG. 4 shows the configuration of the congestion information processing server in the first embodiment of the present invention.

  The congestion information processing server 1 includes a communication unit 101, a vehicle congestion information creation unit 102, a congestion information DB 103, a charging unit 104, an authentication unit 105, a session control unit 106, and a diagram management DB 107.

  The communication unit 101 communicates with the user's portable information terminal 3 via the public network 4 and communication within the train operation subsystem via the closed communication network 2, for example, vehicle congestion information data of each vehicle from the train. It has a function to transmit and receive.

  The vehicle congestion information creation unit 102 creates congestion information based on congestion sensor output data from a congestion sensor (not shown) provided in the vehicle of each train received by the communication unit 101 and stores the congestion information in the congestion information DB 103. At the same time, the congestion transition information is updated with the congestion information. When there is a request from the user, the congestion information DB 103 is searched based on the request and response data to be provided to the user is created.

  When creating congestion information, the time at which the data is acquired and the data are digitized to generate congestion information, and the congestion information for each station, train ID, and vehicle ID assigned to the congestion sensor output data. Store in the DB 103.

  When it is determined that the congestion transition information pattern input by the user and analyzed by the session control unit 106 is a pattern that emphasizes real-time characteristics, the vehicle congestion information creation unit 102 is the train nearest to the target station. Is identified from the schedule management DB 107, and congestion information is acquired from the congestion information DB 103 based on the train ID. For example, referring to the schedule management DB 107 based on the time information input from the user and the target station, the train A is identified as the nearest train arriving at the user's boarding station, and the train B is closest to the user's scheduled departure station The congestion information DB 103 is searched based on the train ID of the train, the congestion status of the train stored in the congestion information DB 103 of the train A is acquired, the user is notified, and the train B The congestion transition information up to the station to get off is acquired and notified to the user.

  Further, when the congestion transition information pattern input by the user is a pattern that places importance on the past, the train departing from the nearest station at the requested time is identified with reference to the diagram management DB 107 and corresponds to the train ID, for example, One week of congestion information is acquired from the congestion information DB 103, and this is used as congestion transition information.

  The congestion information DB 103 holds the latest congestion information created by the vehicle congestion information creation unit 102 and the congestion transition information updated by the congestion information.

  The session control unit 106 analyzes a congestion request including a time from the user, a departure station, a scheduled departure station, a congestion transition information pattern, and the like.

  The authentication unit 105 performs user authentication for the congestion request from the user acquired by the communication unit 101. There are many possible user authentication methods, such as a method of using an identifier and password for identifying a user, and a method of combining an individual identifier and password of a mobile phone, but the present invention is limited to a specific user authentication method. is not.

  The charging unit 104 has a function of charging the mobile information terminal that provided the service. Note that there are many charging methods such as pay-per-use based on the amount of data transferred at the time of communication and monthly fixed charging, but the present invention is not limited to a specific charging method.

  The diagram management DB 107 stores train schedule information corresponding to a train ID uniquely assigned to each train.

  The operation in the above system will be described below.

  FIG. 5 is a system operation sequence according to the first embodiment of the present invention.

  Step 101) Congestion sensor output for each vehicle immediately after the train (A) 12 and the train (B) 11 depart from the station (a) 21 to the station (d) 24, via the closed communication network 2. The information processing server 1 is notified. At this time, the congestion sensor output includes a train ID, a vehicle ID, and congestion sensor data. The congestion sensor output is video data showing the inside of the vehicle when the congestion sensor is a camera, and numerical data such as a weight value when the congestion sensor is a pressure sensor.

  Step 102) The communication unit 101 of the congestion information processing server 1 receives the above congestion sensor output, and the vehicle congestion information creation unit 102 totals the congestion sensor output for each train ID / vehicle ID to create congestion information. Store in the information DB 103.

  Step 103) The portable information terminal 3 requests congestion information from the congestion information processing server 1 via the public network 4. The request includes data for designating a time at which the user wants to get on, a departure station, a destination station, and a desired congestion transition information pattern.

  Step 104) When the congestion information processing server 1 receives a request from the user at the communication unit 101, the authentication unit 105 performs user authentication, and the session control unit 106 determines whether the request is appropriate, If it is not, the request is output to the vehicle congestion information creation unit 102. The vehicle congestion information creation unit 102 specifies the nearest train 11 approaching the user vicinity station 22 by searching the diagram management DB 107 based on the requested time, the departure station, and the arrival station, and the identified train The congestion information DB 103 is searched based on the train ID of the train station, and the congestion information from the boarding stations of the 25 most recent trains (train 12) is acquired to the station 25 scheduled to get off in step 102 so far. Vehicle congestion transition information, which is a set of information, is created as response data.

  Step 105) The communication unit 101 of the congestion information processing server 1 responds the created response content data to the portable information terminal 3 of the user via the public network 4.

In step 101 described above, one or a plurality of cameras installed for each vehicle are used as a congestion sensor for detecting vehicle congestion, and video data taken inside the vehicle is transmitted via the closed communication network 2 including the mobile wireless communication section. It transmits to the congestion information processing server 1. The mobile wireless communication section may be a dedicated line that is a part of the closed communication network 2 and uses a dedicated radio wave, or may be a general wireless LAN or a mobile phone network. The present invention is not limited to a specific network type. For example, a digital camera is used as the camera. When obtaining the congestion information from the video data, an image analysis means (not shown) is provided in the vehicle congestion information creation unit 102. For example, when the train floor is visible, what percentage is compared to the case of passenger 0 For example, the degree of congestion may be evaluated as a three-stage evaluation of A to C. In that case,
A (vacant): 81% ~
B (Normal): 21-80%
C (congestion): ~ 20%
And this is used as congestion information and stored in the congestion information DB 103.

In addition, as another congestion sensor, one or a plurality of pressure sensors installed for each vehicle is used, and the congestion change is made via the closed communication network 2 including the mobile wireless communication line by outputting the weight change data and the passenger number data. It transmits to the information processing server 1. As the pressure sensor, for example, a sensor utilizing a piezoelectric effect of a semiconductor is considered. The congestion information in this case is that the weight of the vehicle is known and stored in a memory or the like, and the difference between the total weight of each vehicle (including the weight of the person on board) and the weight of only the known vehicle is calculated. From the obtained and obtained values, for example, by performing a three-stage evaluation of A to C,
A (empty): ~ 3000kg
B (normal): 3001 kg to 5000 kg
C (congestion): 5001kg ~
This is obtained as congestion information and stored in the congestion information DB 103.

  Furthermore, as a sensor for detecting other congestion information, a radio wave transmitted from a mobile phone attached to a passenger or a tagged ticket is detected by in-vehicle equipment, and the detection data is closed including a mobile radio communication line. A method of transmitting to the congestion information processing server 1 via a communication network is also conceivable. The number of passengers for each vehicle can be calculated by detecting and counting individual identification signals from the radio waves.

  Furthermore, as another congestion sensor, there is a sensor of a system that outputs a congestion degree by a camera image installed on a station platform. The camera video data is transmitted from the station to the congestion information processing server 1 via the closed communication network 2. In this case, the closed communication network 2 may or may not include a wireless line, but the present invention is not limited to a specific network type.

  Next, the operation of the congestion information processing server 1 will be described.

  FIG. 6 shows an operation sequence of the congestion information processing server in the first embodiment of the present invention.

  Step 51) In the communication unit 101 of the congestion information processing server 1, sensor outputs from the congestion sensors of the trains 11 and 12 are received via the closed communication network 2.

  Step 52) When the sensor output is video data, the vehicle congestion information creation unit 102 performs a process of digitizing from the video data. When the sensor output is pressure data, the weight value is obtained by the above method, and the congestion is obtained. The congestion information DB 103 is updated by giving a train ID / vehicle ID as information.

  Step 53) The communication unit 101 receives a congestion status acquisition request from the portable information terminal 3 via the public network 4, and the authentication unit 105 performs user authentication. The request from the user includes the time of the train for which information is desired, the departure station, the scheduled departure station, the congestion transition information pattern, and the like.

  Step 54) The session control unit 106 determines whether or not the request content is appropriate. If it is appropriate, the process proceeds to Step 55, and if it is inappropriate, the process proceeds to Step 56.

  Step 55) The vehicle congestion information creating unit 102 acquires the congestion information stored in the congestion information DB 103 based on the request from the portable information terminal 3, creates the congestion transition information for the request, and proceeds to step 57. .

  Step 56) The session control unit 106 creates an error notification and notifies the user from the communication unit 101 via the public network 4.

  Step 57) The communication unit 101 transmits the congestion transition information as response data to the portable information terminal 3 via the public network 4.
