  2. Description of the Related Art Conventionally, a technique for collecting information in a house or the like by remotely operating a sensor installed in the house or the like from a user side via a network has been developed. For example, Patent Document 1 discloses a technique in which a TV camera is installed in a house, the imaging range of the TV camera is controlled from the outside, and the obtained video signal can be received and confirmed via the Internet. ing. Alternatively, Patent Document 2 discloses a technique in which a mobile robot is placed inside a home or the like, the robot can be controlled from a remote place, and the control result can be determined from a camera image from the robot. Each of the above-described conventional techniques determines information such as a video signal obtained by a user or the like who is away from home or in a remote place. Since judgment or interpretation of information is made on the user side, there is a problem that a significant load is imposed on the user side.

In order to solve the above-described problems, conventionally, a technique for sharing a function for judging or interpreting information on the sensor side installed in a house or the like has been developed. FIG. 10 shows a conventional technique for remotely operating a sensor installed inside a house or the like from the outside. 10, reference numeral 77 is a house, etc. 78 is a sensor such as a camera installed in the house 77, 79 is a home appliance such as a refrigerator installed in the house 77, 76 is outside the house 77, etc. A mobile phone or other terminal. On the camera 78 side, a fixed video pattern is prepared in advance so that a home appliance 79 such as a refrigerator can be recognized. For example, a video pattern in which the door of a household electric appliance 79 such as a refrigerator is closed and a pattern in an open state are prepared. As a result, when the camera 78 captures a video pattern in which the door of the home appliance 79 such as a refrigerator is open, for example, the camera 78 determines that the door of the home appliance 79 such as the refrigerator is open by matching with the video pattern. Or it can be interpreted. When performing a remote operation on an object, a fixed video pattern of the object before and after the remote operation is prepared in advance on the camera 78 side, so that the camera 78 side similarly shows the result of the remote operation. Judgment or interpretation is also possible.

  As described above, a fixed video pattern is prepared in advance so that the object can be recognized on the camera 78 side, and the captured video is judged by comparing the captured video with the video pattern. Interpretation is possible. However, for example, when an accident or the like occurs and an image different from a fixed image pattern prepared in advance on the camera 78 side is captured, the camera 78 cannot determine or interpret the image. When such an accident or the like occurs, the user of the information terminal at a remote location must control the camera 78 to collect a large number of videos and then determine or interpret what has occurred. As a result, there has been a problem that a user of an information terminal located at a remote location from the location where information such as an accident occurs takes a considerable burden and takes a very long time to judge or interpret the information that has occurred. On the other hand, when the camera 78 is regarded as a sensor, its role or use is single and unambiguous. For this reason, there has been a problem that it is necessary to install a large number of cameras 78 or the like in a house 77 or the like according to various roles or applications. Even if the camera 78 installed in the house or the like 77 can be taken outside, it cannot cope with the change in information acquired from the camera 78, and the camera 78 can be used dynamically and universally.

  FIG. 4 shows an information retrieval system 130 according to the third embodiment of the present invention. In FIG. 4, the portions denoted by the same reference numerals as those in FIGS. In FIG. 4, reference numerals 90-3, 90-4, etc. are vehicles, L1, L2, Ln are parking lanes of a parking lot, L1 (h), L2 (h), Ln (h) (h = 1, 2, 3). ,..., M) are the parking positions of the parking lanes L1, L2, and Ln, respectively, and 50b is an empty vehicle that is an example of the information source 50, like the accident vehicle 50a, 52a-1, 52a-2, 52a-n is an example of a meta information issuing device similar to the beacon 52a. Each beacon of the parking lanes L1, L2, Ln, 20a-3, 20a-4 is an information terminal similar to the information terminal device 20a-1, etc. These are wireless terminals installed in vehicles 90-3 and 90-4, respectively, which are one embodiment of the apparatus 20. As shown in FIG. 4, the information INFOb generated in the third embodiment is the empty vehicle position (information on the vehicle) of the empty vehicle 50 b, and the meta information METAb transmitted from the beacon 52 a-1 is, for example, “empty vehicle position”. . The content “empty vehicle position” of the meta information METAb is used when the wireless terminal 20a of the vehicle 90 or the wireless terminal 20a-3 of the vehicle 90-3, which is located far from the position of the empty vehicle 50b, searches for the empty vehicle position. It is one of the categories that can be. Therefore, as long as it shows the same category, the content of other meta information, for example, “parking situation” can be set. Alternatively, contents of a plurality of similar meta information items such as “empty vehicle position” and “parking lot situation” may be grouped, and arbitrary contents in the group may be used as the meta information METAb.

  As shown in FIG. 4, the information INFOb (empty vehicle) acquired by the image pickup device 22a-2 by the information collection unit 30a-2 of the wireless terminal 20a-2 of the vehicle 90-2 that has exited from the parking position L1 (m-2). The meta information METAb (empty vehicle position) transmitted from the beacon 52a-1 is added to the position image) and recorded in the recording unit 24a-2. The information search unit 35a-2 receives the information request QRYb-3 made using the search meta-information METAb (empty vehicle position) from the wireless terminal 20a-3 of the other vehicle 90-3, and the recording unit 24a-2. The information INFOb (empty vehicle position image) to which the meta information that matches the search meta information METAb (empty vehicle position) is added is searched from the information recorded in the information. When the information INFOb (empty vehicle position image) is searched, the search result includes the searched information INFOb (empty vehicle position image) or the information INFOb (empty vehicle position image) with the meta information METAb (empty vehicle position) for search. The information RESb-2 is transmitted to the wireless terminal 20a-3 side of another vehicle 90-3 (two or more units) that requested the information. When the received search result information RESb-2 includes information INFOb (empty vehicle position image), the information request unit 40a-3 (not shown) of the wireless terminal 20a-3 uses the received search result information RESb-2. Recording is performed in the recording unit 24a-3 (not shown) of the wireless terminal 20a-3. Similarly, for the vehicle 90-4 that has exited from the parking position Ln (3), the radio terminal 20a-4 also includes the beacon 52a-n in the information INFOb (empty vehicle position image) acquired by the image pickup device 22a-4 (not shown). The meta information METAb (empty vehicle position) transmitted from is attached and recorded in the recording unit 24a-4 (not shown). In response to an information request QRYb-3 made using the search meta information METAb (empty vehicle position) from the radio terminal 20a of another vehicle 90, the search meta information from the information recorded in the recording unit 24a-4 Information INFOb (empty vehicle position image) to which meta information that matches METAb (empty vehicle position) is attached is searched. When the information INFOb (empty vehicle position image) is searched, the search result includes the searched information INFOb (empty vehicle position image) or the information INFOb (empty vehicle position image) with the meta information METAb (empty vehicle position) for search. The information RESb-4 is transmitted to the wireless terminal 20a side (two or more units) of the other vehicle 90 that has requested the information. When the received search result information RESb-4 includes information INFOb (empty vehicle position image), the information request unit 40a of the wireless terminal 20a stores the received search result information RESb-4 in the recording unit 24a ( (Not shown).

Although not shown in FIG. 4, it is assumed that the vehicle 90-1 has come out of the parking position L1 (3) and has already been parked at the parking position L1 (m-2). That is, the information INFOb (empty vehicle position image) with the meta information METAb (empty vehicle position) was not originally recorded in the recording unit 24a-2 of the vehicle 90-2, or the information terminal 20a-2 once recorded the information INFOb (empty vehicle position). It is assumed that the information INFOb (empty vehicle position image) is deleted based on the image captured by the image pickup device 22a-2 after the position image) is recorded. In this case, the search meta information METAb (empty vehicle position) is transferred from the wireless terminal 20a-3 of the vehicle 90-3 to the wireless terminal 20-1 of the vehicle 90-1 via the wireless terminal 20a-2 of the vehicle 90-2. The used information request QRYb-3 can be performed. Since the wireless terminal 20a-2 does not search for information with meta information matching the search meta information METAb (empty vehicle position), the information relay unit 38a-2 wirelessly transmits information to the information request unit 40a-2 (not shown). An information request QRYb-2 (not shown) using meta information METAb (empty vehicle position) for search is transmitted to the terminal 20a-1 side (may be two or more). In the recording unit 24a-1 of the wireless terminal 20a-1, information INFOb (empty vehicle position image) captured by the image pickup device 22a-1 and attached with the meta information METAb (empty vehicle position) is recorded. Similarly to the second embodiment, information INFOb (empty vehicle position image) or search meta information METAb (empty vehicle position) is attached from the wireless terminal 20a-1 to the wireless terminal 20a-3 via the wireless terminal 20a-2. The search result information RESb-2 including the information INFOb (empty vehicle position image) can be transmitted.

  As described above, according to the third embodiment of the present invention, the wireless terminal 20a-1 of the vehicle 90-3 far from the empty vehicle position 50b is connected to the wireless terminal 20a-2 of the vehicle 90-2 that exists in the vicinity of the empty vehicle position 50b. An information request QRYb-3 using the meta information METAb (empty vehicle position) is made, and information INFOb (empty vehicle position image) generated in the front or meta information METAb (empty vehicle position) for search is attached as a response RES-2 to this The search result information RESb-2 including the information INFOb (empty vehicle position image) can be received. Similarly to the second embodiment, the wireless terminal 20a-3 of the vehicle 90-3 uses the information relay function of the vehicle 90-2, and thus the vehicle that exists in the vicinity of the empty vehicle position (for example, the parking position L1 (3)). Information request QRY-3 using the meta information METAb (parking position) can also be made to the wireless terminal 20a-1 of 90-1. The response RES-2 (= RES-1) includes information INFOb (empty vehicle position image) generated in the front or the information INFOb (empty vehicle position image) attached with the search meta information METAb (empty vehicle position). The search result information RESb-2 can be received via the wireless terminal 20a-2. That is, when the wireless terminal 20a-3 of the vehicle 90-3 existing behind the information generation source (empty vehicle position) 50b obtains information generated in the front, first, predetermined meta information METAb (empty vehicle position) is set as a category. The information request QRYb-3 can be made to the radio terminal 20a-2 of the vehicle 90-2 close to the information generation source 50b. As a response, search result information RESb- including information INFOb (empty vehicle position image) corresponding to the meta information METAB (empty vehicle position) or the information INFOb (empty vehicle position image) with the meta information METAb (empty vehicle position) for search added. 2 can be easily obtained. For this reason, after receiving a large amount of information INFOk (k = 1, 2, 3,...) Collected by the information generation source 50b, a significant load is imposed on the judgment or interpretation of the large amount of information INFOk. It will not take much time and will not take much time.
