Description

The present invention relates to a broadcast disaster prevention radio system and a broadcast disaster prevention radio broadcasting method, and more particularly, to a broadcast disaster prevention radio system and a broadcast disaster prevention radio broadcasting method capable of reducing the number of IDs (Identifiers) to be called.

  The following are known radio communication systems used for purposes such as disaster prevention. The wireless communication system disclosed in Japanese Patent Application Laid-Open No. 2011-188169 (Patent Document 1) includes a center station, an outdoor loudspeaker station, and a door-to-door receiver, and the center station includes an operation console and a master station device. In this system, a collective number, a group number, and an individual number are set as the slave station identification number corresponding to the report type, and a group report can be made even in the emergency collective report method.

  Hereinafter, an identification number for identifying individual slave stations is referred to as an individual ID, and an identification number for collectively specifying a plurality of slave stations belonging to the same group is referred to as a group ID.

  A disaster prevention broadcast wireless system disclosed in Japanese Patent Application Laid-Open No. 2012-004877 (Patent Document 2) includes a master station device and a slave station device, and the master station device includes a wireless transmission / reception device and a console. The wireless transmission / reception apparatus broadcasts disaster prevention information to the slave station apparatus. In addition, areas such as river flood assumption areas and earthquake disaster risk areas are set in advance, and when calling, the area is selected, and the slave station devices registered in association with the area are extracted and called. .

JP2011-188169 JP2012-004877

  In Patent Document 1, a group name is input as a transmission target when performing group notification, and an individual name is input when performing individual notification. The group name corresponding to the group ID is associated with a plurality of predetermined individual IDs.

  For this reason, when it is desired to arbitrarily specify individual IDs to be called, for example, when calling is performed by arbitrarily setting an area, the probability that a specified group of individual IDs can be covered by one group ID is low. As described above, the group ID designates a plurality of predetermined individual IDs (that is, a plurality of predetermined slave stations) at a time, so it is desired to make a call to an arbitrary area. In this case, it is difficult to specify a slave station existing in the arbitrary area with one existing group ID. Therefore, an operation for designating a plurality of individual IDs is performed, and as a result, there is a problem that it takes time to call all the slave stations.

  In Patent Document 2, a slave station associated with an area to be called is extracted, but since the area is registered in advance as in Patent Document 1, a target area cannot be arbitrarily set at the time of calling.

  When a call operation is performed from the console, the time required for the call increases in proportion to the number of selected IDs, but it is desirable to reduce the time required for the call as much as possible. Time reduction is especially important for emergency applications such as disaster prevention. It is effective to use the group ID for shortening the time, but it is difficult to grasp in short time which group ID each slave station belongs to.

  An object of the present invention is to solve the above-described problems and to perform a broadcast radio system capable of shortening a call time to a slave station by reducing the number of IDs used as much as possible even when an individual ID to be called is arbitrarily designated. Is to provide.

  The present invention is a disaster prevention broadcast radio system having a master station and a slave station having an individual ID, wherein the master station has a console, the console has a storage unit and a control unit, and the storage unit Is stored with the individual ID and the group ID to which the individual ID belongs, the control unit designates a plurality of individual IDs to be called, and queries the storage unit for the group ID to which the plurality of designated individual IDs belong. The broadcast disaster prevention radio system is characterized in that at least one conversion from an individual ID to a group ID to which the ID belongs is performed and the slave station is called using the group ID.

  Further, the present invention is a disaster prevention broadcast radio master station having a console and a master station radio device, wherein the console has a storage unit and a control unit, and the storage unit includes the individual ID and a group to which the individual ID belongs. ID is stored, the control unit specifies a plurality of individual IDs to be called, inquires of the storage unit the group ID to which the specified plurality of individual IDs belong, and from each individual ID to the group ID to which it belongs The broadcast disaster prevention radio master station is characterized by performing at least one conversion and instructing the master station radio device to call a slave station using the group ID.

  The present invention is also a disaster prevention broadcast radio broadcasting method having a master station and a slave station having an individual ID, wherein the master station has a console, and the console has the individual ID and a group ID to which the console belongs. When a plurality of the individual IDs are specified by the console, the storage unit is inquired of the group ID to which the plurality of individual IDs belong, and the individual ID is converted to the group ID to which the individual ID belongs. The broadcast disaster radio broadcasting method is characterized in that at least one is performed and the slave station is called.

  In the present invention, when calling a plurality of individual IDs, the number of IDs can be reduced to shorten the calling time.

It is a block diagram which shows the 1st Embodiment of this invention. It is a flowchart explaining the operation | movement of the 1st Embodiment of this invention. It is a figure explaining conversion from individual ID to group ID in a 1st embodiment of the present invention.

(First embodiment)
<Configuration of Embodiment>
FIG. 1 is a block diagram showing a first embodiment of the present invention. The present embodiment is a disaster prevention broadcast wireless system, and includes a master station 100 and a plurality of slave stations 3A, 3B, 3C. Hereinafter, the slave stations 3A, 3B, and 3C are collectively referred to as a slave station 3 unless particularly distinguished.

  The master station 100 includes a console 1, a master station radio device 2, and a map display device 4. The console 1 includes a control unit 11, a memory unit 12, a display unit 13 (display), and an input unit 15. The input unit 15 is, for example, a mouse, a touch panel, a keyboard, or the like, and may include a plurality or all of these.

  The map display device 4 includes a display control unit 41, a map storage unit 42, and a display unit 43 (display). Two display units may not be provided, and one display unit may be shared by the console 1 and the map display device 4. The master station wireless device 2 communicates with the console 1 by wire and performs wireless communication with each slave station 3 in accordance with an instruction from the console 1.

  The called slave station 3 receives the radio from the master station radio device 2 and performs an instructed operation such as a loud sound broadcasting. The slave station stores its own individual ID and group ID. When the slave station is specified by the group ID or individual ID transmitted from the master station wireless device 2, the transmitted information is broadcast. The broadcast contents are, for example, warning sirens and disaster prevention information by voice.

  The slave stations 3A and 3C are outdoor loudspeaker slave stations, and the slave station 3B is a door-to-door receiver. An outdoor loudspeaker station is fixedly installed outdoors and broadcasts with a loudspeaker. Door-to-door receivers are installed in homes and offices and broadcast in the same way.

  The memory unit 12 includes an individual ID of the slave station and a group ID to which the slave station belongs, a correspondence table between the slave station, location information of the slave station, information to be transmitted to the slave station, a type of slave station (outdoor loudspeaker slave station, individual receiver, etc.), etc. Is remembered. These pieces of information are registered in the memory unit 12 in advance by a slave station information registration unit (not shown).

  The console 1 has a function of operating and controlling the entire system and calculating optimum ID conversion. The control unit 11 controls the master station 100, and based on the operator's input from the input unit 15, obtains the individual ID and group ID from the memory unit 12 and the map to be displayed on the map display device 4. A slave station and individual ID are designated, a slave station call instruction to the master station wireless device 2 and a display instruction to the display unit 13 are performed. The control unit 11 is configured by a CPU (Central Processing Unit). The console 1 may be a dedicated device or may be a software that is installed in a general PC (Personal Computer) to realize the function.

  When a broadcast operation is performed on the console 1, when an area to be broadcast or a target slave station (usually a plurality of slave stations) is selected, the individual ID of the selected slave station belongs to the group ID managed by the memory unit 12. When the ID matches, the control unit 11 replaces the individual ID with the group ID.

  The map display device 4 displays a map of a broadcast area, and includes a display control unit 41, a map storage unit 42, and a display unit 43, and the position, individual ID, and type of a slave station are displayed on the map. The display control unit 41 links the map information stored in the map storage unit 42, the slave station location information stored in the memory unit 12 and sent via the control unit 11, and the individual ID information, and displays them on the display unit 43.

Note that the map information and the location information of the slave stations are registered in advance in the map storage unit 42 by a map information registration means (not shown). The slave station position information, individual ID information, and slave station type registered in the memory unit 12 may be registered in the map storage unit 42.
<Operation of Embodiment>
FIG. 2 is a flowchart for explaining the operation of the present embodiment, and FIG. 3 is a diagram for explaining the replacement from the individual ID to the group ID in the present embodiment. “Child” in FIG. 3 indicates a slave station.

  First, the operator selects an area to be broadcast on the map screen of the map display device 4 (S301). In FIG. 3, the map itself is omitted. The selection is performed by clicking and dropping with the mouse as shown in FIG. 3 ((1) in FIG. 3) or by touching with a finger or pen → sliding → dropping in the case of a touch panel. When an area is selected, all the slave stations in that area are selected. In order to individually select a slave station (slave station 1003 in this embodiment) instead of selecting an area, a (Ctrl + click) operation or a tap operation (operation to tap with a finger) is performed ((2) in FIG. 3). For example, this method is used when you want to select an area after adding it, when it is difficult to select an area because there are slave stations that you want to select and slave stations that you do not want to select. This is used to select individual slave stations. In this embodiment, both area range selection and individual selection are used, but only one of them may be used.

  Next, the control unit 11 searches the information of the child station 3 existing in the range selected in step S301, and extracts all individual IDs of the child stations existing in the range (S302).

  The control unit 11 makes an inquiry to the memory unit 12 and replaces the extracted individual ID with the group ID to which it belongs, so that the number of IDs is as small as possible (S303).

  This conversion is illustrated in FIG. FIG. 3 is a diagram for explaining selection of a slave station and subsequent conversion from an individual ID to a group ID. There are five slave stations displayed on the screen, and the individual IDs are 1000, 1001, 1003, 1025, 1100. It is assumed that there are four individual IDs of broadcast target slave stations 1000, 1001, 1003, and 1025. The slave stations with individual IDs 1000, 1001, and 1003 belong to group ID 2000, and the slave stations with individual IDs 1025 and 1100 belong to group ID 2001.

  The control unit 11 makes an inquiry to the memory unit 12 and determines that three of 1000, 1001, and 1003 are individual IDs belonging to the group ID 2000, and therefore replaces 1000, 1001, and 1003 with the group ID 2000. However, the individual ID 1025 belongs to 2001, not the group ID 2000, and 2001 includes an individual ID 1100 that is not a call target in addition to 1025. For this reason, the individual ID 1025 is not converted into a group ID, and a call is made with the individual ID as it is. The IDs finally designated and called by the control unit 11 are the individual ID 1025 and the group ID 2000 ((3) in FIG. 3).

  Thereafter, the control unit 11 instructs the master station radio device 2 to start calling with the specified ID (S304). The master station wireless device 2 broadcasts to the called slave station 3 (S305) and ends.

  If there is character data or image data of the broadcast content, it can be confirmed by displaying it on the display unit 13. If it is audio, it should be output from a speaker (not shown).

  In this way, the number of call target IDs is reduced from four to two, and the call time can be automatically halved without any special action by the operator. By reducing the calling time, it is possible to broadcast quickly even in cases where urgent action is required, such as evacuation and evacuation such as tsunami warning and emergency earthquake warning. If a function for selecting a range on a map is used, the operator can broadcast in a short time.

  In the example of FIG. 3, only one group ID is used for calling, but naturally there may be a plurality of IDs, and the effect of reducing the number of IDs is further enhanced. However, even in that case, only one group ID may be used for calling, and other IDs may be called with individual IDs. As long as the number of IDs to be called decreases, it is effective.

  In the example of FIG. 3, the area is selected as a rectangle, but if it can be selected in an arbitrary shape by freeform and freehand, accurate selection can be performed in a shorter time.

  In FIG. 3, the individual IDs of the slave stations are displayed on the map screen of the display unit 43, but the operator may feel complicated and may not be displayed. In FIG. 3, the slave stations are displayed on the map screen from the beginning. However, if the slave stations are displayed after the area range is selected, the complexity is further reduced. The presence / absence of the display of the individual ID and the display timing of the slave station may be changed according to the complexity of the map.

  If a slave station is not automatically selected in the selected area and the slave station is displayed after selecting the area range, the slave stations may be individually selected by the above Ctrl + click or tap operation. This is convenient when it is desired to exclude a part of the slave stations existing in the area.

  In the above embodiment, the broadcasting area is selected on the map, and the slave stations included in the area and the individual IDs are extracted. However, the target district is 10 to 20 in A ward or B city C district or the like. If it is known, a method of selecting it from the input unit 15 may be used.

  For this purpose, address and district information is stored in the memory unit 12 and displayed in a list on the display unit 13 for selection. Alternatively, address information such as city, street address, and district is stored in the map storage unit 42 in a linked manner with the map, and displayed in a list on the display unit 13 for selection.

  Also, when the slave station is an outdoor loudspeaker, the area selection becomes more accurate if the range in which the voice reaches by the loudspeaker is displayed together with the slave station. It is also helpful to display the type of the slave station, for example, a loudspeaker or a door-to-door receiver, together with accurate selection.

  In addition, since the area range selection is performed by clicking and dropping with the mouse, the accuracy of the range selection may be deteriorated when the operator is in a hurry. If there is a slave station that is close to the outside of the selected range, the neighboring slave station may be displayed by changing the display color or blinking to alert the operator.

In addition, the slave station may have a function of not only receiving the broadcast from the master station but also providing a response such as reception confirmation from the slave station to the master station.
(Second Embodiment)
In the first embodiment, when only the group ID (complete match) to which the individual IDs belonging to the call target are all used for calling and one non-target slave station is included (incomplete match), the group ID is Individual ID is used without using. However, if, for example, 90% of a plurality of individual IDs under a certain group ID are to be called, calling may be performed using the group ID. The remaining 10% is an unnecessary call, but the time can be further reduced. Here, this 90% is called the coincidence rate.

  It is also possible to set the coincidence rate on the console 1. For example, it is assumed that the operator sets the matching rate to 80% or more from the input unit 15 to the control unit 11. When 85% of the individual IDs included in the converted group ID are call targets, the group ID is used. However, in the case of 75%, the individual ID is not converted into the group ID but is called as it is. In order to reduce the number of individual IDs that do not need to be called as much as possible, it is desirable that the matching rate be a predetermined rate or more.

  In addition, when an area is selected or a slave station is individually selected, there may be a group ID that includes only the individual ID to be called and only a group ID that includes other than the individual ID to be called. . Even in that case, a group ID having a matching rate equal to or higher than a predetermined value may be used for calling.

  In the first and second embodiments described above, the content to be broadcast is not limited to disaster prevention information itself, but includes disaster information, warnings, a search cooperation request for missing persons, and the like. The voice information may be information prepared in advance or information spoken by the operator on the spot. The console can be equipped with a microphone and speakers.

  Moreover, not only audio | voice information but character information, image information, or those combination may be sufficient. The image information is, for example, a route to an evacuation site if it is an evacuation instruction.

  The present invention can be used, for example, in a 60 MHz band digital broadcast disaster prevention radio system.
