In each figure, the same components are denoted by the same reference numerals, and redundant description is omitted. FIG. 1 is an arrangement diagram of a schematic configuration of a sediment disaster monitoring system employing a sediment disaster monitoring apparatus 10 according to the present invention. The earth and sand disaster monitoring apparatus 10 is provided in the monitoring center S, for example.

  The monitoring place G is an enlarged view near the sabo dam as shown in FIG. 2, for example. At the monitoring location G, where the gravel / rock where the IC chips 30-1 to 30-n are embedded is expected, the IC chips 30-1 to 30-n called non-contact IC tags or the like are located. An information reading device 20 (in FIG. 1, 20-1 to 20-3) is installed. The information reading device 20 is called a reader / writer, transmits information for writing or electromagnetic waves for reading through an antenna, and receives radio waves by an antenna coil provided in the IC chips 30-1 to 30-n. Give rise to The IC chips 30-1 to 30-n that have received radio waves via the antenna coil are configured to transmit the received write information or transmit information such as an ID stored therein. The information reading device 20 is configured to receive information such as an ID transmitted by the IC chips 30-1 to 30-n.

  It should be noted that the IC chips 30-1 to 30-n embedded in the gravel / rock are at least a unique ID (identification information) stored and can be written once and cannot be rewritten. good. Moreover, it is not necessary to write the ID or the like by the information reading device 20, and it can be written in advance by another reader / writer. The IC chips 30-1 to 30-n are fixed to the surface of gravel or rock with a caulking material or the like, or are installed in a depression in sand.

  The IC chips 30-1 to 30-n are embedded in gravel / rock, for example, in three stages (large, medium and small), and their IDs are managed. Further, the IDs of the IC chips 30-1 to 30-n are managed separately for each area where the gravel and rocks in which the IC chips 30-1 to 30-n are embedded are arranged. Here, the area refers to an area in which one information reading device 20 can detect an IC chip having a radius of about 10 m and the range is divided into several areas.

  FIG. 3 shows a table included in the determination unit 12 described later for the above ID management. Here, the case where the area is divided into areas # 1 to # 6 is shown, and the size of the gravel / rock is shown in three stages of large, medium and small. In addition, in the presence / absence detection column, for example, gravel and rocks embedded with an IC chip are all arranged in an area that can be read by the information reading device 20 at the beginning. It is. Unlike this example, the gravel / rock embedded with the IC chip can be initially placed in an area that cannot be read by the information reader 20, and a part of the gravel / rock embedded with the IC chip is initially It can also be detected when it is arranged in an area readable by the information reading device 20.

  In FIG. 4, the block diagram of the earth and sand disaster monitoring apparatus 10 is shown. The earth and sand disaster monitoring apparatus 10 includes an information collecting unit 11, a determining unit 12, and an alarm transmitting unit 13. The information collecting unit 11 collects the read information from the transmission unit of the information reading device 20 that reads the information of the IC chip embedded in the gravel / rock by the receiving unit via a wireless or wired line. The determination means 12 determines whether or not the gravel / rock has moved based on the information of the IC chip embedded in the gravel / rock and the collected information. The determination means 12 has the table T shown in FIG. 3, and with reference to this, for example, information on the IC chip embedded in the gravel / rock that was initially detectable is read by the information reader 20. When it becomes impossible to detect, it is determined that there is movement. The alarm transmission unit 13 transmits alarm information based on the determination result by the determination unit 12.

  The alarm transmission means 13 is an apparatus that transmits alarm information based on at least one of voice, character information, and alarm sound via a line. Specifically, the information is transmitted from the information processing apparatus 40 shown in FIG. The apparatus 50 and the information storage server 60 are configured. An information terminal 70 such as a personal computer is connected to the information processing apparatus 40.

  When the judging means 12 of the earth and sand disaster monitoring device 10 judges that there is a movement to the gravel / rock, an alarm level is determined according to the movement state and is converted into corresponding message information or the like by the information processing device 40. The voice response device 50 sends a voice message. The voice response device 50 makes a call using telephone number information set in advance, for example, calls the telephone P in the home H of FIG. 1 and sends a voice message as a response. Data converted into corresponding message information in the information processing apparatus 40 is stored in the information storage server 60 or displayed on a display panel D provided at various places such as roads via a wired line or a wireless line. A message and control data are sent as data, or sent to a contact panel device R provided in each home via a wired line or a wireless line, and an alarm is generated and output by display or alarm sound.

  The earth and sand disaster monitoring apparatus 10 according to the above configuration is configured by a computer, and each unit shown in FIG. 3 is realized by executing a program corresponding to the flowchart shown in FIG. The operation will be described below with reference to the flowchart shown in FIG. The ID data of the IC chip detected by the information reading device 20 is received via the line, and written in the column of presence / absence of detection in the new table T of ID management shown in FIG. 3, and the new table T is completed (S1).

  Following step S1, it is detected whether there is a change in the detection presence / absence column with reference to the new table and the original table (S2), and if there is a change, whether a warning is output or not is determined for a predetermined number of IC chips. Determination is made when ID data is no longer detected (S3). In other words, when gravel or rock with embedded IC chip information flows away from the detection area of the information reader 20, an alarm is output when a predetermined number of IC chip ID data is no longer detected. It is.

  When the ID data of the predetermined number of IC chips is not detected, the process proceeds from step S3 to step S4, and the alarm level is detected (S4). For example, in the case of up to two areas # 1 to # 6, it is reported that there is a sign of a landslide disaster. In the case of 3-4, the risk of a landslide disaster is reported. In addition, the occurrence of earth and sand disaster shall be reported. In addition, if only information on IC chips embedded in small gravel or rock is detected among large, medium and small gravel and rock, a sign of sediment disaster will be reported. If the information on the IC chip embedded in is no longer detected, the risk of sediment disaster will be reported. If the information on the IC chip embedded in large gravel or rock is no longer detected, A major danger of landslide disaster or occurrence of landslide disaster shall be reported.

  The detected alarm level information is converted into corresponding message information or the like in the information processing device 40 and sent to the voice response device 50 as a voice message. The voice response device 50 makes a call using a predetermined telephone number. Call the required telephone and send a voice alarm message in response to the other party's response (S5). Further, the data converted into the corresponding message information in the information processing apparatus 40 is stored in the information storage server 60 or sent as display data to the display panel D provided at various places such as roads via a line. Alternatively, alarm data is sent to the contact panel device R provided in each home via a wireless line or a wired line, and an alarm message corresponding to the alarm data is output from the contact panel device R by voice or display. (S5).

  As shown in FIG. 1 as the information reading devices 20-1 to 20-3, a plurality of information reading devices 20 are installed. Therefore, the earth and sand disaster monitoring device 10 collects information from each information reading device. Thus, the landslide disaster monitoring is performed as described above for the range covered by each information reading device, and an alarm including a district name corresponding to the range is generated when necessary. Therefore, according to the embodiment of the present invention, the movement of the gravel / rock is detected based on the original information of the IC chip embedded in the gravel / rock and the collected IC chip information, and the occurrence monitoring of the landslide disaster is monitored. Since a general-purpose IC chip is used, a special sensor is not required, and a new IC chip is embedded in gravel or rock even when a monitoring configuration is constructed again due to the occurrence of a sediment disaster. It is easy to maintain.

  In the above embodiment, an example is shown in which only the ID is stored in the IC chip and operated. However, the area information and the size information of the gravel / rock are stored in the IC chip as information other than the ID. May be used to detect the alarm level. In addition, all the IC chips embedded in the gravel / rock were initially placed in a range detectable by the information reading device 20, but were initially embedded in the gravel / rock in a range undetectable by the information reading device 20. The presence of movement may be detected when all the IC chips are arranged and the information of the IC chip embedded by the movement of gravel or rock is detected. Initially, a part of the IC chip embedded in gravel / rock is placed in a range detectable by the information reader 20, and the rest is placed in a range undetectable by the information reader 20, and the gravel / rock The presence of movement may be detected when the information of the IC chip embedded by the movement of is detected or when the information of the IC chip cannot be detected. Further, an alarm may be generated when movement can be detected in gravel / rock with a predetermined number of IC chips embedded without performing detection at an alarm level.
