Description

  The present invention relates to a data collection system capable of collecting data related to equipment installed at each stop and requiring maintenance and inspection in a server of a base station.

  For example, ticket vending machines, ticket gates, and checkout machines installed at stations and bus stops require regular or irregular maintenance work. Conventionally, such maintenance work is performed by maintenance personnel. Had to go around the station and bus stop regularly or irregularly.

  However, regular maintenance and inspection work by maintenance personnel consumes a great amount of time and labor, and is inefficient.

  Therefore, data related to equipment such as ticket vending machines, ticket gates, and checkout machines is aggregated by a data aggregation machine installed at each station, and the aggregated data is input to the information processing terminal in the base station from each data aggregation machine. A system has been devised (see Patent Document 1).

JP 2000-251178 A

  By the way, the above-mentioned patent document does not describe in detail how data is input from each data aggregation machine to the information processing terminal in the base station. It is assumed that they are connected to the Internet individually. Such a system is based on the premise that there is a wide-area communication infrastructure in which the data aggregator provided at each station and the information processing terminal of the base station are connected so that they can communicate with each other. It cannot be used in areas that are not. Therefore, maintenance and inspection work for equipment installed at bus stops and streetcars that operate in depopulated areas where there is no wide-area communication infrastructure has to be carried out by maintenance personnel. .

  The present invention has been made paying attention to such problems, and its main purpose is to install it at each stop via a vehicle that travels by a fixed route even in an area where a wide-area communication infrastructure is not established. It is an object of the present invention to provide a data collection system capable of collecting data related to the maintenance status of the equipment.

  That is, the present invention provides a vehicle-side information processing terminal that is provided in a server provided in a base station and a vehicle that moves along a certain route and that can transmit and receive data to and from the server by wireless communication, and the vehicle can stop. It is a data collection system constructed by a stop-side information processing terminal provided at a stop and capable of receiving maintenance data from vehicle-side information processing by wireless communication.

  Here, the “vehicle” of the present invention may be any vehicle that moves regularly or irregularly on a certain route, as well as a route bus, a train (including a tram), and a ferry. A vehicle (for example, a postal delivery car, a parcel delivery car, a newspaper delivery car, a milk delivery car, etc.) is also included. The “stop” means a stop point (for example, a bus stop, a station, a ferry stop, etc.) set as appropriate according to the type of vehicle. Examples of the “maintenance inspection target device” include a ticket vending machine, a ticket gate, a checkout machine, and various measuring instruments. In addition, “maintenance data” that is data related to the maintenance status of the maintenance / inspection target device is data provided to determine whether or not the device is operating normally. The maintenance data is digital data composed of any one or a combination of an image, text, sound, and script, and the image includes both a still image and a moving image.

  The data collection system of the present invention includes a maintenance data collection unit that collects data related to the maintenance status of a maintenance / inspection target device that requires regular or irregular maintenance inspection as a stop-side information processing terminal, and a maintenance data collection unit. Maintenance data transmitted from the stop-side communication means as the vehicle-side information processing terminal by applying the maintenance data collected in step 2 to the vehicle-side information processing terminal by wireless communication. Can be received by wireless communication, and the maintenance data transmitted from the vehicle side communication means as a server is applied using a vehicle equipped with vehicle side communication means capable of transmitting the received maintenance data to the server by wireless communication.

  If it is such a data collection system, the maintenance data collected by the maintenance data collection means of the stop side information processing terminal provided in the stop is transmitted to the vehicle side information processing terminal provided in the vehicle operating on a certain route, Furthermore, since the maintenance data is transmitted from the vehicle side information processing terminal to the server provided in the base station by wireless communication, the vehicle side information processing terminal functions as a fixed access point where the stop side information processing terminals are scattered. If the vehicle stops or passes within an area where wireless communication between the terminal and the information processing terminal is possible, the information processing terminal on the stop side can transmit maintenance data to the information processing terminal on the vehicle side using the communication means on the stop side. Maintenance data received by the vehicle at each stop is stored and stored in the maintenance data storage means of the server, and installed at each stop. It can be efficiently collected vessels of the maintenance data to the base station. Therefore, in areas where the base station and each stop are not connected so that they can communicate with each other, or where the stops are not connected so that they can communicate with each other, that is, in areas where a wide-area communication infrastructure is not established. Even in such cases, maintenance data for each stop can be collected at the base station via a vehicle, and maintenance personnel regularly check the operating status of equipment installed at a stop in a depopulated area where a wide-area communication infrastructure is not established. There is no need to go around and check, and maintenance and inspection can be performed efficiently.

  In the data collection system of the present invention, maintenance data reproducing means for reproducing at least one of maintenance data received by the server-side communication means or maintenance data stored / stored in the maintenance data storage means is used as a server. Further, it is preferable to apply one provided. Here, as the “maintenance data reproduction means”, a mode in which an image or text is displayed on a display, a mode in which sound is emitted from a speaker, or a light emitting element such as an LED or a light emitting body is turned on / flashes according to the content of a script. An embodiment, or a combination thereof. With such a server, the content of the maintenance data can be grasped instantaneously and easily on the base station side, and a quick response is possible.

  In particular, in the data collection system of the present invention, a unique identifier is attached to each stop, and the stop side communication means transmits maintenance data associated with the stop identifier to the vehicle side communication means. it can. In this way, it is possible to accurately grasp which stop device is normal or abnormal.

  The maintenance data reproducing means 34 is configured by using a display 3d (see FIG. 1) arranged at a predetermined location of the base station C, received by the server side communication means 32, and stored / accumulated by the server side maintenance data storage means 33. Maintenance data is displayed on the display 3d. The display 3d is one of the devices provided in the server 3. The display 3d has a built-in speaker or is externally connected. When the maintenance data is a single voice or includes voice, a sound corresponding to the maintenance data is emitted from the speaker.

  Next, referring to FIG. 3, the processing procedure of each information processing terminal (bus side information processing terminal 2, bus stop side information processing terminal 1) and server 3 in the data collection system S having the above-described configuration is a flow of maintenance data. It explains along. In FIG. 3, an arrow indicated by a relatively thick line indicates a flow of maintenance data, and an arrow indicated by a relatively thin line indicates a process flow of the data collection system S.

  A unique identifier is attached to each bus stop A in advance, and the base station C stores and manages the location information of the bus stop A in association with each identifier. At each bus stop A, the bus stop-side information processing terminal 1 collects maintenance data regarding the equipment Ax installed at each bus stop A by the maintenance data collecting means 12, and the collected maintenance data is stored in the bus stop-side maintenance data storage means 13. Is stored and accumulated in the storage device 1a.

  In this state, when the bus B operating on a certain route enters the bus stop A and stops, the bus stop side information processing terminal 1 detects the presence of the bus B by the bus stop side bus detection means 11 (S1, Hereinafter, “step” is abbreviated as “S”). Whether or not the bus B is detected by the bus stop side bus detection means 11 depends on whether or not the communication between the wireless communication device 1b of the bus stop information processing terminal 1 and the wireless communication device 2b of the bus side information processing terminal 2 is successful. Can be determined. When the bus stop side bus detection means 11 detects the bus B (S1; Y), the bus stop side information processing terminal 1 uses the bus stop side communication means 14 to collect maintenance data (the identifier information of the bus stop A). Maintenance data) is transmitted to the bus-side information processing terminal 2 by wireless communication (S2). Then, the bus side information processing terminal 2 receives the maintenance data transmitted from the bus stop side communication means 14 of the bus stop side information processing terminal 1 by wireless communication by the bus side communication means 21 (S3), and the bus side maintenance data storage means. 22 to store / accumulate in the storage device 2a.

  The above procedure is repeated for each bus stop. Thereafter, when the bus B enters the base station C from outside the base station C and stops, the server 3 detects the bus B by the server-side bus detection means 31 (S4). Whether or not the bus B is detected by the server-side bus detection means 31 can be determined depending on whether or not the communication between the wireless communication device 1b of the server 3 and the wireless communication device 2b of the bus-side information processing terminal 2 is successful. it can. When the bus B is detected by the server-side bus detection means 31 (S4; Y), the bus-side information processing terminal 2 uses the bus-side communication means 21 to store maintenance data stored and stored in the bus-side maintenance data storage means 22. It transmits to the server 3 by wireless communication (S5).

  Next, the server 1 receives the maintenance data transmitted from the bus side communication means 21 by wireless communication by the server side communication means 32 (S6), and stores / accumulates it in the storage device 3a by the server side maintenance data storage means 33. The maintenance data is displayed on the display 3d by the maintenance data reproducing means 34 (S7). When the maintenance data includes sound, the sound is emitted from the speaker.

  Through the above processing procedure, maintenance data that is data relating to the maintenance status of the equipment Ax installed at each bus stop A can be collected in the server 1.

  In addition, the data collection system S according to the present embodiment collects maintenance data related to the equipment Ax installed at each bus stop A regularly or irregularly (as needed) by the maintenance data collecting means 12 in the bus stop side information processing terminal 1. Thus, the maintenance data stored in the bus stop side maintenance data storage means 13 is configured to be updated regularly or irregularly (as needed), and the bus side of the bus B that patrols the route and stops at the bus stop A again. To the information processing terminal 2, maintenance data that is newer than the maintenance data already stored and stored in the bus-side maintenance data storage means 22 of the bus B is transmitted by the bus stop-side communication means 32, and the bus-side maintenance data storage is performed. The maintenance data stored / accumulated in the means 22 is updated. Each time the route travels around and returns to the base station C, the bus-side information processing terminal 2 and the server 3 repeat the above steps (S4 to S7). Thereby, the updated maintenance data is displayed on the display 3d of the server 3.

  As described above, the data collection system S according to the present embodiment uses the route bus B that regularly operates a certain route, and uses the maintenance data of Ax installed at each bus stop A as the bus side of each bus stop A. Information can be collected in the server 3 of the base station C that is not connected to the information processing terminal 2 by wireless communication. Therefore, even in an area where a wide-area communication infrastructure is not established, maintenance data regarding the equipment Ax of each bus stop A can be efficiently collected in the server 3, and the equipment Ax of each bus stop A can be normally collected in the base station C. It is possible to easily grasp whether or not it is operating. As a result, it is possible to effectively save the maintenance staff from visiting each bus stop periodically or irregularly to maintain and inspect the equipment, thereby improving the efficiency of the maintenance inspection.

  Moreover, the data collection system S according to this embodiment can instantly and easily grasp the contents of the maintenance data on the base station C side by reproducing the maintenance data by the maintenance data reproduction means 34 of the server 1. Quick response is possible. Furthermore, in the data collection system of the present embodiment, a unique identifier is assigned to each bus stop A, and maintenance data associated with the identifier of the bus stop A is transmitted to the bus side communication means 21 by the bus stop side communication means 14. Since it is configured, it is possible to accurately grasp which bus stop A device Ax is in a normal or abnormal state.

  In addition, this invention is not limited to embodiment mentioned above. For example, in the above-described embodiment, an example in which a bus is applied as a vehicle and a bus stop is applied as a stop is illustrated. However, the maintenance data collection system according to the present invention uses a vehicle that moves on a certain route. Any device that collects maintenance data of equipment installed at a stop where it can stop can be widely applied. Therefore, a train (including a tram) and a ferry can be adopted as a vehicle, and a station or a ferry anchorage (a ferry landing) can be adopted as a stop. Further, as a vehicle, a vehicle that plays a role of delivering a target object along a certain route to a personal home or a company such as a postal delivery car, a delivery car, a newspaper delivery car, or a milk delivery car may be applied. Depending on the type of vehicle, the equipment placed (installed) at the stop is also changed (for example, if the vehicle is a train, the stop will be a station, and the equipment installed at this station may be a ticket gate, a checkout machine, etc. For example). It is also possible to use vehicles that travel irregularly on a certain route (temporary buses, temporary trains, temporary delivery vehicles, etc.).

  In addition, not only when the vehicle stops at the stop, but also when the vehicle passes (including slow travel) without stopping at the stop, maintenance data is transmitted and received between the vehicle-side information processing terminal and the stop-side information processing terminal by wireless communication. You may be able to do it.
