  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the following description, components having the same function may be denoted by the same reference numerals and description thereof may be omitted.

(First embodiment)
(Constitution)
FIG. 1 is a block diagram showing the configuration of a broadcasting equipment group and a master station equipment in the broadcast radio system according to the first embodiment of the present invention.

  As shown in FIG. 1, the broadcasting equipment group of the present invention includes a remote control station equipment 1, an automatic startup device 2, an external startup device 3, and an operator console 5. Each of the remote control station equipment 1, the automatic starter 2, the external starter 3, and the console 5 is also called a broadcast equipment as a single unit. Among these, the remote control station equipment 1, the automatic starter 2 and the external starter 3 are not essential components, and are selected to be connected or not connected depending on the size and purpose of use of the broadcast radio system. You can do it. As the automatic starter 2, for example, there is a national instantaneous warning system (J-ALERT) receiver.

  Further, the master station equipment of the present invention comprises a wireless transmission / reception device 4 and an operator console 5 as shown in FIG. The console 5 has a recording unit 6, a control unit 7, a calculation unit 8, and an interface (I / F) unit 9 as functional units.

(Function)
Unless otherwise specified, the operation of the embodiment will be described assuming that the “broadcast facility priority value” is smaller and the “broadcast facility priority” is higher. Here, the “broadcast facility priority value” and the “broadcast facility priority” are indices indicating the priority order of the broadcast facility. The “broadcast facility priority value” and the “broadcast facility priority” are set for each broadcast facility. The “broadcast facility priority value” is represented by a numerical value, and the minimum value is zero.

  Here, the external activation device 3 whose “broadcast facility priority value” is 1 transmits an emergency broadcast (broadcast A), and the wireless transmission / reception device 4 broadcasts the broadcast A within 5 minutes. The case where the remote control station equipment 1 whose “broadcast equipment priority value” is 5 transmits an emergency broadcast (broadcast B) later will be described. Here, the broadcast request is a signal for requesting that the wireless transmission / reception device 4 perform broadcasting. The broadcast request is transmitted from the broadcast facility for each broadcast. The I / F unit 9 receives a broadcast request transmitted from the broadcast facility.

  At this time, a broadcast request is transmitted from the remote control station facility 1 whose “broadcast facility priority value” is 5. The I / F unit 9 receives a broadcast request transmitted from the remote control station facility 1 whose “broadcast facility priority value” is 5.

  FIG. 2 is a flowchart for explaining the operation of the calculation unit according to the first embodiment of the present invention.

  In order to determine whether interrupt broadcasting is possible, when the operation unit 8 starts operation (start), first, it is confirmed whether or not the wireless transmission / reception device 4 is broadcasting (step S1). Here, determining whether or not interrupt broadcasting is possible can also mean determining whether or not the broadcast radio system performs broadcasting by interruption.

  In step S1, when the wireless transmission / reception device 4 is not broadcasting (step S1no), the calculation unit 8 performs the operation of step S1 again from the beginning.

  In step S1, when the wireless transmission / reception device 4 is broadcasting (step S1yes), the calculation unit 8 confirms whether the I / F unit 9 has received a broadcast request during a predetermined time. (Step S2).

  In step S2, when the I / F unit 9 has not received a broadcast request (step S2no), the calculation unit 8 performs the operation of step S1 again from the beginning.

  When the I / F unit 9 receives a broadcast request in step S2 (step S2yes), the arithmetic unit 8 then performs the “broadcast priority” of the broadcast being broadcast (broadcast A) and the broadcast request of broadcast A. "Broadcasting facility priority" of the broadcasting facility (broadcasting facility A), the "broadcasting priority" of broadcasting (broadcasting B) corresponding to the broadcasting request received later, and the broadcasting request received later The broadcasting facility (broadcasting facility B) of “the broadcasting facility” is acquired (step S3). Here, the “broadcast priority” is an index indicating a broadcast priority, and includes, for example, “general” and “emergency”. “Emergency” is given priority over “General”. “Broadcast facility priority” may be referred to as a first priority, and “broadcast priority” may be referred to as a second priority.

  Each “broadcast facility priority” acquired by the calculation unit 8 may be recorded in the recording unit 6 in advance. Then, the calculation unit 8 acquires the “broadcast facility priority” corresponding to the broadcast facility with which the I / F unit 9 is communicating from the recording unit 6. Alternatively, each “broadcasting facility priority” used by the calculation unit 8 for comparison may be acquired by communication between the broadcasting facility that is the source of the broadcast request and the I / F unit 9 of the console 5. In this case, the calculation unit 8 acquires “broadcast facility priority” from the I / F unit 9.

  Next, the calculation unit 8 determines whether or not to change the “priority of the broadcast facility” of the broadcast facility A (step S4). For example, it is possible to set a determination criterion such that it is determined that the change is made if one minute or more has elapsed since the start of the broadcast A and that it is determined that the change is less than one minute since the start of the broadcast A. .

  If it is determined in step S4 that the broadcast facility A is to be changed (step S4 yes), the calculation unit 8 next changes the “broadcast facility priority” of the broadcast facility A acquired in step S3 (step S10). More specifically, for example, the calculation unit 8 acquires the “broadcast facility priority value” of the broadcast facility A, and if the broadcast facility A has passed n minutes according to the elapsed time from the start of broadcast of the broadcast A, The “broadcast facility priority value” is added to n (n is an integer). Then, the computing unit 8 changes the “broadcast facility priority” of the broadcast facility A according to the changed “broadcast facility priority value” of the broadcast facility A. As another change method, a method of lowering the “broadcast facility priority” of the broadcast facility that is the source of the repeat broadcast request in accordance with the number of repeated broadcasts or the elapsed broadcast time is also conceivable. Here, the repeated broadcast is to broadcast the same contents repeatedly in one broadcast in order to make information known to the residents. In an emergency, an emergency broadcast or general broadcast with a finite number of repetitions or an unlimited number of broadcasts is broadcast, and the operator of the broadcast requesting broadcast facility is evacuated. When the broadcast time of these broadcasts is long and the “broadcast facility priority” of the broadcast facility that requested the broadcast is high, it is not possible to broadcast from other broadcast facilities by interruption. In such a case, for example, after 5 minutes from the start of broadcasting, the “broadcasting equipment priority” of the broadcasting equipment requesting repeated broadcasting is lowered, or the repeated broadcasting is repeated every time the number of repeated broadcasting is increased by one. Assume that the "broadcasting facility priority" of the requesting broadcasting facility is lowered. As a result, it becomes possible to transmit a broadcast that is more important to the repeated broadcast from another broadcast facility and broadcast with interruption. As another modification method, for broadcasts such as broadcast radio scheduled broadcasts and automatic broadcasts that need to be broadcast but the importance of the broadcast content is low, the broadcast request source broadcast facility immediately after the start of the broadcast It is conceivable to lower the “broadcasting equipment priority”. As a result, it is possible to reliably broadcast a broadcast that is meaningful to be broadcast, and to broadcast a more important broadcast by interruption during the broadcast.

  In step S4, when it is determined as NO (step S4no), the calculation unit 8 does not change the “broadcasting facility priority” of the broadcasting facility A.

  Next, the calculation unit 8 determines whether or not the “broadcast priority” of the broadcast A has priority over the “broadcast priority” of the broadcast B (step S5).

  In step S5, if the “broadcast priority” of the broadcast A is a priority (step S5 yes), the calculation unit 8 determines that the interrupt broadcast is not possible, and informs the control unit 7 of this result (step S8), and performs processing. End (end).

  In step S5, if the “broadcast priority” of the broadcast A is not prioritized (step S5no), the arithmetic unit 8 then selects the “broadcast priority” of the broadcast A and the “broadcast priority” of the broadcast B. It is determined whether or not “” is equivalent (step S6).

  In step S6, if the “broadcast priority” of broadcast A is equal to the “broadcast priority” of broadcast B (step S6yes), then the calculation unit 8 then sends the “broadcast facility priority” of broadcast facility A. It is determined whether the “priority” is higher than the “priority of broadcasting equipment” of the broadcasting equipment B (step S7).

  In step S6, if the “broadcast priority” of broadcast A is not equal to the “broadcast priority” of broadcast B (step S6no), then the operation unit 8 determines that interrupt broadcasting is possible and performs control. The result is transmitted to the unit 7 (step S9), and the process is terminated (end).

  In step S7, if the “broadcast facility priority” of the broadcast facility A is equal to or higher than the “broadcast facility priority” of the broadcast facility B (broadcast priority of the broadcast facility A ≧ broadcast of the broadcast facility B) ) (Step S7yes), the calculation unit 8 determines that interrupt broadcasting is not possible, transmits this result to the control unit 7 (step S8), and ends the processing (end).

  In step S7, if the “broadcasting facility priority” of the broadcasting facility A is lower than the “broadcasting facility priority” of the broadcasting facility B (the broadcasting priority of the broadcasting facility A <the broadcasting priority of the broadcasting facility B). (Step S7no) Next, the calculation unit 8 determines that interrupt broadcasting is possible, and transmits this result to the control unit 7 (step S9), and ends the processing (end).

  The calculation unit 8 starts the process again from step S1 after completing the process. Moreover, the calculating part 8 is good also as starting the process of step S1, after a fixed time passes, after complete | finishing a process. By doing so, it is possible to reduce the average processing load per hour, and thereby the effect of reducing power consumption can be expected.

  Alternatively, the calculation unit 8 may wait until the operation start instruction is received from the control unit 7 after the processing is completed. In this case, the control unit 7 continues to check whether the I / F unit 9 has received a broadcast request. When it is confirmed that the I / F unit 9 has received the broadcast request, the control unit 7 instructs the calculation unit 8 to start operation. When the operation unit 8 receives an operation start instruction from the control unit 7, the calculation unit 8 starts processing from step S <b> 1.

  When the control unit 7 receives the result of the determination of whether or not interrupt broadcasting is possible from the calculation unit 8, the control unit 7 instructs the wireless transmission / reception device 4 to perform broadcasting by interruption as interrupt broadcasting processing. When the wireless transmission / reception device 4 receives an instruction from the control unit 7 to broadcast by interruption, the wireless transmission / reception device 4 broadcasts by interruption.

  In addition, when the control unit 7 receives from the calculation unit 8 the result of the determination as to whether interrupt broadcasting is possible or not, the processing is terminated.

  In this example, the “broadcast priority” is “emergency” in both cases (step S5no, step S6yes). In this example, the broadcast facility (broadcast facility A) that is the broadcast request source of the broadcast being broadcast (broadcast A) is the external activation device 3. Then, when n minutes have elapsed since the start of the broadcast A, when changing the “priority value of the broadcast facility” of the broadcast facility A to “n”, the broadcast A is broadcasted. The “broadcasting facility priority value” within 5 minutes is less than 5. Also, the broadcast facility (broadcast facility B) that is the broadcast request source of the broadcast request received later is the remote control station facility 1 and its “broadcast facility priority value” is 5.

  In this case, the calculation unit 8 determines that the “broadcast facility priority” of the broadcast facility A is higher than the “broadcast facility priority” of the broadcast facility B (step S7yes). Further, the arithmetic unit 8 determines that interrupt broadcasting is not possible as a result of determining whether interrupt broadcasting is possible, and notifies the control unit 7 of the result. In addition, the control unit 7 receives the result of the determination of whether or not interrupt broadcasting is possible from the arithmetic unit 8 and ends the processing.

  In this embodiment, the “broadcast facility priority” of the console 5 that transmits a broadcast request is used as the “broadcast facility priority” of the broadcast facility that is the broadcast request source in automatic broadcast, or the broadcast of automatic broadcast is performed. It is possible to select whether or not to use the priority of the broadcasting equipment registered (requested). Here, the automatic broadcast is a broadcast in which a certain broadcast facility once registers the contents of the broadcast in the console 5 and the console 5 transmits a broadcast request at the date and time designated by the registered broadcast contents.

  For example, when automatic broadcasting is centrally managed by the console 5 having a “broadcasting equipment priority value” of 1 and automatic broadcasting is performed from the remote control station equipment 1 having a “broadcasting equipment priority value” of 8, The contents of the broadcast are once registered in the console 5, and the console 5 transmits a broadcast request at the designated date and time. In this case, the broadcast facility that transmits a broadcast request for automatic broadcast is the console 5, but the broadcast facility that registered the content of the automatic broadcast is the remote control station facility 1.

  At this time, the broadcast facility that is the broadcast request source in the automatic broadcast may be regarded as the remote control station facility 1 in which the content of the broadcast of the automatic broadcast is registered, not the console 5 that transmits the broadcast request.

(effect)
According to the broadcast radio system of this embodiment, while broadcasting a general broadcast transmitted from a certain broadcast facility, another general broadcast transmitted from a broadcast facility having a “broadcast facility priority” higher than that broadcast facility. Can be broadcast by interruption. Further, while an emergency broadcast transmitted from a certain broadcast facility is being broadcast, another emergency broadcast transmitted from a broadcast facility having a higher “broadcast facility priority” than that broadcast facility can be broadcast by interruption. This makes it possible to quickly inform the residents of important information.

(Second Embodiment)
(Constitution)
As a second embodiment of the present invention, in addition to the configuration of the first embodiment described above, while broadcasting a broadcast transmitted from a certain broadcast facility, the “broadcast facility priority” of the broadcast facility is set manually or An embodiment that can be automatically changed to an arbitrary value is conceivable. With such a configuration, more flexible broadcast control is possible.

(Function)
In other words, when particularly important contents are being broadcasted, the priority of the broadcasting equipment being broadcast can be increased to prevent interruption broadcasting with respect to the broadcasting being broadcast. When the broadcast content is repeated or when the content of low importance is being broadcast, the priority of the broadcasting equipment being broadcast can be lowered to permit interrupt broadcasting for the broadcast being broadcast.

(effect)
According to the present embodiment, it is possible to prevent unexpected interruption broadcasts for broadcasts that are being broadcast, and to quickly and surely inform the residents of important information as a whole system.

The information on the surrounding environment includes, for example, the number of people around the person, the actions of the people, the amount of chemical substances such as odorous substances and radiation.

  Then, the console 5 or the remote control station equipment 1 changes its “broadcasting equipment priority” based on the information about the surrounding environment acquired from various sensors.

  For example, each of the console 5 and the remote control station equipment 1 collects the number of people in the vicinity and the movement of the people with a human sensor, a sound sensor, a vibration sensor, a camera, and the like. The movement of setting “priority” is assumed. Also, if there are broadcasting facilities near active volcanoes, chemical factories, nuclear power plants, etc., collect environmental information from chemical sensors, odor sensors, radiation sensors, etc., and those values are high. Judgment is made and the “broadcasting equipment priority” of the broadcasting equipment is set high. Thereby, the broadcast control of preferentially broadcasting the broadcast from the broadcasting facility in an emergency can be realized. In the present embodiment, whether or not to change the “priority of the broadcasting equipment” of the broadcasting equipment during broadcasting can be arbitrarily determined in advance.

(effect)
According to the present embodiment, it is possible to realize broadcast control in which broadcasts from broadcast facilities in an emergency situation are preferentially broadcast.
