Description

  The present invention relates to an information distribution system for distributing transmission information to station employees.

When train schedules are disrupted due to accidents or breakdowns, station staff (station office in-house station staff) provides information (communication information) necessary for train operations such as train operation arrangement results and delay information (cause of delay, recovery information, etc.) , Home station staff, etc.). Since such transmission information was transmitted using telephone, facsimile, voice broadcasting, etc., station employees had to listen to the transmission information, or had to go to the station staff for information obtained at the station office. As a result, the communication information was not quickly transmitted to all station employees. Therefore, a system has been devised in which such transmission information is displayed on a display screen of a personal computer or a mobile terminal connected to a network so that station employees can quickly know the transmission information (see Non-Patent Document 1).

  The information number 3041 stores a unique number added to each comprehensive transmission information data 304. The command determination time 3042 is the time when the passenger commander determines that the transportation arrangement data 301 corresponding to the comprehensive transmission information data 304 is to be delivered to the station employee, or the information type from the command terminal 3 by the passenger commander. And the time when the information content is input is stored. The train number 3043, the information type name 3049, the information content 3050, the target section start station 3045, and the target section end station 3047 are data extracted from the corresponding transport arrangement data 301 stored in the transport arrangement DB 201. Train type 3044, target section start station departure time 3046, and target section end station arrival time 3048 are data extracted from the plan diagram DB 207 based on the train number 3043.

  The station corresponding to the train number stored in the train number 3043 (hereinafter referred to as “the train”) is the closest to the current station 3051 from the name of the station where the train is currently stopped or the current position among the stopped stations. The station name of the station is stored. The current station arrival time 3052 to the current station planned number line 3054 and the current station predicted number line 3057 are extracted based on the train number 3043 and the current station 3051 from the predicted / actual diagram data 302 stored in the predicted / actual diagram DB 202.

Is extracted and the total transmission information data 304 is created. In FIG. 7, at Tokyo Station, there is no change in the numbering line associated with the change in the operation line, so the current station planned numbering line 3054 and the current station predicted numbering line 3057 are the same “No. 1 line”. However, at Hamamatsucho Station, the numbering line is changed from Line 1 to Line 2, so that “No.1” is stored in the next station planned numbering line 3061, but “2” is stored in the next station predicted numbering line 3064. It is memorized as “number line”.

  Another example will be described with reference to FIG. For example, when the “train delay” occurs for the operation of the train with the train number “117M”, the train number and delay time of the delayed train are automatically extracted from the prediction / results diagram DB 202. According to the extracted data, the estimated arrival time of each station arriving from now is obtained, and comprehensive transmission information data 304 is created. In FIG. 8, since there is no influence of train delay at Tokyo Station, the current station departure delay time 3056 is “0”. However, since a train delay of 3 minutes occurs at Hamamatsucho Station, the next station arrival delay time 3062 and the next station departure delay time 3063 store “3” as the delay time.

  9 and 10, the terminal-oriented transmission information DB 205 includes terminal-oriented transmission information data 305-1, 305-2,..., 305-j (hereinafter collectively referred to as "terminal-oriented transmission information data 305"). Is stored for each terminal-specific file 205a. The terminal file is a data file set for each station employee terminal 500, and stores a terminal code 4064 for identifying the corresponding station employee terminal 500 in association with it. The terminal-oriented transmission information data 305 is data indicating transmission information distributed to each station employee terminal 500, and is created by extracting necessary data from the general transmission information data 304, the prediction / results diagram data 302, and the plan diagram DB 207. It is data. The terminal transmission information data 305 includes information number 4051, train number 4052, train type 4053, station planned arrival time 4054, station planned departure time 4055, station planned departure line 4056, station predicted arrival time 4057, station Predicted departure time 4058, predicted station number line 4059, information type name 4060, information content 4061, transmission importance 4062, confirmation presence 4063, instruction determination time 4064, and the like are stored in association with each other.

  In the information number 4051, the train number 4052, the train type 4053, and the command determination time 4064, the information number 3041, the train number 3043, the train type 3044, and the command determination time 3042 of the corresponding general transmission information data 304 are extracted and stored. . In the station planned arrival time 4054 to the station planned departure line 4056, data extracted from the plan diagram DB 207 based on the station where the station employee terminal 500 corresponding to the train number 4052 and the terminal code 4064 is arranged is stored. . In addition, the station where the station employee terminal 500 corresponding to the terminal code 4064 is arranged becomes clear by referring to a station employee registration DB 206 described later.

  Data extracted from the prediction / results diagram data 302 based on the station where the station employee terminal 500 corresponding to the train number 4052 and the terminal code 4064 is placed in the predicted predicted arrival time 4057 to the predicted predicted departure line 4059. Is memorized. The transmission importance 4062 stores the importance calculated by executing the importance determination processing by the importance determination unit 12. In the confirmation presence / absence 4063, whether or not the station employee has confirmed the display related to the distributed transmission information data 305 for the terminal is stored. “0” is stored as an initial value, and “1” is displayed when the display related to the transmission information data 305 for the corresponding terminal is confirmed on the station employee terminal 500 (read), and “0” is displayed when the display is not confirmed (unread). Remembered.

  This will be described more specifically. When the comprehensive transmission information data 304-1 shown in FIG. 7 is created by the processing unit 1, based on the train number 3043 and the plan diagram DB 207, the delivery destination determination unit 11 distributes the comprehensive transmission information data 304-1 ( (Related station) and target line. For example, it is assumed that the station employee terminal 500 with the terminal code “Hama001” is carried by the station employee of the No. 1 platform at Hamamatsucho Station. Since the target section is Yurakucho Station-Shinagawa Station in the general transmission information data 304-1, Hamamatsucho Station is a related station. Furthermore, since the information content 3050 is “change from the down line to the down line, change from line 1 to line 2”, the station employee terminal 500 arranged on the 1st and 2nd lines of Hamamatsucho Station is the distribution destination. It is determined. Here, in the change of the number line due to the change of the operation line, the transmission information data 305 for the terminal is distributed to both the number lines before the change (planned number line) and after the change (predicted number line). Accordingly, terminal-oriented transmission information data 305-1 is created in the terminal-specific file 205a corresponding to the terminal code “Hama001”.

  The transmission importance 4062 stores the importance calculated by the importance determination unit 12 based on the importance weight data 212. Details of the calculation of importance will be described later. In the confirmation presence / absence 4063, “0” is stored as an initial value. Then, the processing unit 1 instructs the communication unit 4 at a predetermined timing to acquire the confirmation status of the terminal-related transmission information data 305 distributed to each station employee terminal 500. “1” is stored in the confirmation information 4063 of the transmission information data 305 for the terminal confirmed by the station employee.

  Another example will be described with reference to FIG. When the general transmission information data 304-2 shown in FIG. 8 is created by the processing unit 1, the distribution destination determination unit 11 determines the related station and the target number line based on the train number 3043 and the plan diagram DB 207. In the comprehensive transmission information data 304-2 shown in FIG. 8, since the target section is from Shimbashi Station to Shinagawa Station, Hamamatsucho Station is a related station. Further, since there is no change in the numbering line, the station employee terminal 500 arranged on the first line of the Hamamatsucho station indicated by the next station planned numbering line 3061 is determined as the delivery destination. Accordingly, terminal-oriented transmission information data 305-2 is created in the terminal-specific file 205a corresponding to the terminal code “Hama001”.

  Returning to FIG. The importance level determination unit 12 performs a process of calculating the importance level of the transmission information data 305 for the terminal based on the importance level weight data 212 according to the importance level determination program 210. The importance is set in, for example, six levels of 0 to 5, and a higher numerical value indicates that the importance of the transmission information data 305 for the terminal is higher. The degree of importance is an index indicating how important the transmission information data 305 for a terminal to be distributed is for a station employee having the station employee terminal 500. For example, when a train delay occurs, in the section where the train is delayed, the information related to the delayed train is highly important for the station staff of the station where the train stops. Therefore, the importance of the terminal-related transmission information data 305 distributed to the station employee terminal 500 owned by the station employee at the stop station is set high. On the other hand, in the section where the train is operated in a delayed manner, the information regarding the delayed operation is not so much related to the business for the station staff of the station through which the train passes. Therefore, the importance of the terminal-related transmission information data 305 distributed to the station employee terminal 500 owned by the station employee of the passing station is set low. In this way, the importance is set for the occurrence of an abnormality, and the station staff is made aware of the importance of the transmitted information data 305 for the terminal, so that the station duties can be performed and the situation guidance to the passenger at the time of the occurrence of the abnormality. It can be done smoothly.

  FIG. 11 is a diagram illustrating an example of the data configuration of the importance weight data 212. The importance weight data 212 stores, for each information type, the station conditions and importance that are the targets of importance addition in association with each other. FIG. 11A is a diagram showing the importance weight data 212a regarding the operation line change. The importance weight data 212a stores stop station weight data 2121 in the changed section and passing station weight data 2122 in the changed section.

  FIG.11 (b) is a figure which shows the importance weight data 212b regarding a train delay. The importance weight data 212b includes stop station weight data 2123 in the delayed arrival section, passing station weight data 2124 in the delayed arrival section, stop station weight data 2125 in the normal time arrival section, and passing station data in the normal time arrival section. Weight data 2126 is stored.

  The importance level determination will be described in detail with reference to FIG. In FIG. 12A, a train 99 is a rapid train that starts at Tokyo Station 91, passes through Yurakucho Station 92 and Shimbashi Station 93, and stops at Hamamatsucho Station 94 and Shinagawa Station 95. According to the transmission information data 305-1 for the terminal, the section (change section) where the operation line is changed is “Yurakucho Station to Shinagawa Station” (section indicated by the arrow 81). Therefore, since the stop stations in the changed section are Hamamatsucho Station 94 and Shinagawa Station 95, the transmission information data 305 for terminals distributed to Hamamatsucho Station 94 and Shinagawa Station 95 is important based on the importance weight data 212a. The degree “5” is added. Further, since the passing stations in the changed section are Yurakucho Station 92 and Shimbashi Station 93, importance “2” is added to the transmission information data 305 for terminals distributed to the stations.

  Next, another example will be described with reference to FIG. According to the transmission information data 305-2 for the terminal, the section where the train delay occurs (delayed arrival section) is “Shinbashi Station-Shinagawa Station” (section indicated by the arrow 83), and the section arriving at the normal time (the normal time) Arrival section) is “Tokyo station to Yurakucho station” (section indicated by arrow 82). Therefore, since the stop stations in the delayed arrival section are Hamamatsucho Station 94 and Shinagawa Station 95, the transmission information data 305 for terminals distributed to Hamamatsucho Station 94 and Shinagawa Station 95 is based on the importance weight data 212b. Importance “4” is added. In addition, since the stop station in the normal time arrival section is Tokyo Station 91, importance “3” is added to the transmission information data 305 for terminals distributed to Tokyo Station 91. The importance “0” is added to the terminal transmission information data 305 distributed to other passing stations (Yurakucho Station 92 and Shimbashi Station 93).

  In addition, the conditions of the station for which the importance is added are not limited to the above. For example, as shown in FIG. 12B, it is assumed that Shinagawa station 95 is a transfer station where two lines intersect. When a train delay occurs, the transmission information data 305 for the terminal is distributed with an importance added to the station employee terminal 500 arranged at a station (for example, Osaki Station 96) on the route that enters the stop station in the delayed arrival section. You may make it do.

  Returning to FIG. The distribution timing determination unit 13 performs processing for determining the distribution timing of the terminal-oriented transmission information data 305 according to the distribution timing determination program 211. Specifically, for example, a difference between the predicted arrival time 4057 of the station corresponding to the train number 4052 stored in the transmission information data 305 for the terminal and the current time is calculated, and the difference is calculated for a predetermined time (for example, 10 Min), the distribution of the transmission information data 305 for the terminal is determined. Then, the information number 4051 of the transmission information data 305 for the terminal for which the distribution decision has been made is stored in the terminal-specific distribution list 213.

  For example, when a train delay occurs at a station far from the own station, and the transmission information data 305 for the terminal is created for the train delay, the station employee terminal 500 arranged at the own station immediately after the creation Even if the transmission information data 305 for the terminal is distributed, if the train arrives at the station several hours later, the necessity of the transmission information data 305 for the terminal at the current time is low, and the station employee transmits the information for the terminal. The contents of the information data 305 must be stored before the train arrives. Therefore, by distributing the transmission information data 305 for the terminal in accordance with the timing at which the train arrives at the station, the station employee can know necessary information at an appropriate timing.

  FIG. 13 is a diagram illustrating a data configuration of the terminal-specific distribution list 213. In the terminal-specific distribution list 213, terminal-specific distribution data 307-1, 307-2, ..., 307-h (hereinafter collectively referred to as "terminal-specific distribution data 307") are stored for each terminal code. Is remembered. In the terminal-specific distribution data 307, a terminal code 5071 and an information number 5072 determined to be distributed by the distribution timing determination unit 13 are stored in association with each other. The information number 5072 is deleted when the terminal-oriented transmission information data 305 corresponding to the information number is distributed, and the information number of the terminal-specific transmission information data 305 distributed at the next timing is newly stored.

  Returning to FIG. The distribution HP generation unit 14 performs processing for generating an HTML file of the transmission information data 305 for terminals to be distributed based on the HP data 214 for terminals. The terminal-oriented HP data 214 stores data necessary for converting the terminal-oriented transmission information data 305 into an HTML file.

  The storage unit 2 stores programs, data, and the like for causing the processing unit 1 to control the information distribution system 100 in an integrated manner. Specifically, transportation arrangement DB 201, prediction / result record DB 202, vehicle operation DB 203, general transmission information DB 204, terminal transmission information DB 205, station employee registration DB 206, plan diagram DB 207, information distribution program 208, distribution destination determination program 209, The importance level determination program 210, the distribution timing determination program 211, the importance level weight data 212, the terminal-specific distribution list 213, the terminal-specific HP data 214, and the like are stored.

  As shown in FIG. 14, the station employee registration DB 206 stores station employee registration data 306-1, 306-2,..., 306-i (hereinafter collectively referred to as “station employee registration data 306”). And memorized. The station employee registration data 306 stores an employee number 5061, a terminal code 5062, a station name 5063, a role 5064, an arrangement position 5065, and the like. The employee number 5061 stores a number for identifying a station employee, and the terminal code 5062 stores a station employee terminal carried by the station employee of the employee number stored in the employee number 5061 or a station employee that can be confirmed. The terminal code of the terminal is stored. The station name 5063 stores the name of the station where the station employee works. The role 5064 stores the role of the station employee (home station employee, ticket office office, etc.). The arrangement position 5065 stores a specific arrangement position of the station employee. For example, if the role of the station employee is “home station employee”, the assigned line name is stored. The communication address 5066 stores an IP address assigned to the station employee terminal 500.

<Process flow>
Next, the flow of processing in this embodiment will be described. FIG. 15 is a flowchart showing the flow of information distribution processing. This process is a process executed by the information distribution system 100 every predetermined time (for example, every minute), and is realized by the processing unit 1 executing the information distribution program 208.

  First, the processing unit 1 executes a delivery destination determination process (step A11). FIG. 16 is a flowchart showing the flow of the delivery destination determination process. This processing is realized by the distribution destination determination unit 11 executing the distribution destination determination program 209.

  First, the delivery destination determination unit 11 extracts from the general transmission information DB 204 the total transmission information data 304 whose target section end station arrival time 3048 is later than the current time (target section end station arrival time ≧ current time) (step A21). . Then, the delivery destination determination unit 11 executes the process of loop A for each comprehensive transmission information data 304 extracted at step A21 (step A22). The delivery destination determination unit 11 extracts a related station based on the target section start station 3045, the target section end station 3047, and the plan diagram DB 207 of the general transmission information data 304 (step A23), and further extracts a target number line (step A24). ). Subsequently, based on the extracted “related station” and “target line”, the corresponding terminal code is extracted from the station employee registration DB 206 (step A25). Then, the terminal-specific transmission information data 305 is created in a file for each terminal corresponding to the extracted terminal code (step A26). The terminal transmission information data 305 is created by combining necessary data of the corresponding total transmission information data 304, the prediction / result diamond DB 202, and the plan diamond DB 207. When the loop A ends (step A27), the distribution destination determination unit 11 ends the distribution destination determination process.

  Returning to FIG. 15, the processing unit 1 executes a distribution timing determination process (step A12). FIG. 17 is a flowchart showing the flow of distribution timing determination processing. This process is realized by the distribution timing determination unit 13 executing the distribution timing determination program 211. First, the delivery timing determination unit 13 executes a loop B for each piece of transmission information data 305 for terminals. The delivery timing determination unit 13 determines whether or not the time obtained by subtracting the current time from the time stored in the station expected arrival time 4057 of the transmission information data 305 for the terminal is equal to or shorter than a predetermined time (for example, 10 minutes) ( Step A32). When it is less than or equal to the predetermined time (step A32; Yes), the distribution timing determination unit 13 stores the information number 4051 of the transmission information data 305 for the terminal in the terminal-specific distribution list 213 (step A33). When the loop B ends, the distribution timing determination unit 13 ends the distribution timing determination process.

  Returning to FIG. 15, the processing unit 1 executes importance level determination processing (step A <b> 13). FIG. 18 is a flowchart showing the flow of importance determination processing. This process is realized by the importance level determination unit 12 executing the importance level determination program 210. First, the importance level determination unit 12 executes loop C for each terminal-specific transmission information data 305 corresponding to the information number stored in the terminal-specific distribution list 213. The importance determining unit 12 calculates the importance based on the importance weight data 212, and stores the calculated importance in the transmission importance 4062 of the terminal-specific transmission information data 305 (step A42). Then, the importance level determination unit 12 determines whether the confirmation presence / absence 4063 of the terminal-specific transmission information data 305 is “0 (unread)” or “1 (read)” (step A43). When the presence / absence of confirmation 4063 is “0” (step A43; Yes), the importance determination unit 12 adds a predetermined value to the importance stored in the transmission importance 4062 (step S44). When the loop C ends, the importance level determination unit 12 ends the importance level determination process.

  Returning to FIG. When the importance level determination process ends, the processing unit 1 lists the terminal-specific transmission information data 305 corresponding to the information number stored in the terminal-specific distribution list 213, and according to the importance of each terminal-specific transmission information data 305. An HTML file is created by identification and distributed via the communication unit 4 (step A14).

<Display screen of station employee terminal>
FIG. 19 is a diagram illustrating an example of an output screen 510 displayed on the display screen of the station employee terminal 500. On the output screen 510, for each terminal-transmitted transmission information data 305 (hereinafter referred to as "transmission information"), a check column 5101, an urgency level 5102, a train number 5103, a transmission time 5104, an information type name 5105, a command decision Time 5106, information content 5107, and the like are displayed for each piece of transmission information.

  A check box is displayed in the check column 5101. When the station employee confirms the transmission information, he enters a mark in the check box. The urgent level 5102 displays a mark indicating that the train subject to transmission information is approaching the station. For example, a mark 5102a is displayed when the predicted arrival time of the train for the train of transmission information is 5 minutes before the current time.

  The train number 5103 displays the train number of the train that is the target of transmission information, and the transmission time 5104 displays the time when the transmission information was distributed. The information type name of the transmission information is displayed in the information type name 5105, and the time when transmission of the comprehensive transmission information data 304 corresponding to the transmission information is determined by the passenger commander is displayed in the command determination time 5106. The information content 5107 displays the information content of the transmission information. Both are displayed based on the data stored in the transmission information data 305 for the terminal.

  In addition, the transmission information is displayed from the top in order of the predicted arrival time of the target train. Further, each piece of transmission information is displayed for each color according to the importance. For example, transmission information with importance 1 or less is displayed with a green background, transmission information with importance 2 to 3 is displayed with a yellow background, and transmission division with importance 4 or more is displayed with a red background.

  Note that an update button (not shown) or the like may be displayed on the display screen 510, and when the update button is selected / pressed, the latest terminal transmission information data 305 may be displayed.

<Action and effect>
As described above, according to the present embodiment, the information distribution system 100 creates the comprehensive transmission information data 304 when data relating to abnormality in train operation is transmitted from the PRC system 200 or input by a passenger commander. Then, for each general transmission information data 304, a related station and target number line to be distributed are selected, and terminal transmission information data 305 for distribution to the corresponding station employee terminal is created. Further, the information distribution system 100 selects the transmission information data 305 for the terminal to be distributed at the present time from the transmission information data 305 for each terminal, calculates the importance of the transmission information data 305, and distributes it to the station employee terminal 500.

  By determining the station and target number line to be distributed for each general transmission information data 305 and selecting the station employee terminal to which the transmission information data 304 for terminals is distributed, the station employee is related to the work at the work station and the arrangement position. Only the transmission information data 305 for the terminal to be received can be received, and the trouble of selecting unnecessary data can be saved. In addition, by setting the distribution timing of the transmission information data 305 for the terminal, the station employee can know necessary information at an appropriate timing. Furthermore, by adding importance to the terminal-related transmission information data 305, station employees can easily recognize the importance of the terminal-specific transmission information data 305 and smoothly perform station operations and provide passengers with status information. It can be carried out.

<Modification>
The application of the present invention is not limited to the above-described embodiment, and can be appropriately changed without departing from the spirit of the present invention. For example, when the transmission information is unread, a predetermined value is added to the importance of the terminal transmission information data 305 corresponding to the transmission information, but an exception may be considered. For example, when the train information related to “train suspension” is resumed after the terminal-related transmission information data 305 related to “train suspension” is distributed to the station employee terminal 500 (resurrection operation), it corresponds to the transmission information data 305 for the terminal If the transmission information to be read is unread, the importance level is not changed. On the other hand, if it has been read, a predetermined value is added to the importance of the transmission information data 305. In other words, the information on the “resurrection operation” that is transmitted later to the station staff who has already read the information about the “train suspension” is more important than the station staff that has not yet read. Therefore, by increasing the importance of the terminal-related transmission information data 305 for the station employee terminal 500 corresponding to the already read station employee, the station employee can be cautioned to change to “resurrection operation”.
