  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, a case where the “priority of broadcasting equipment” of a broadcasting equipment that has transmitted a signal called a broadcast request later is high will be described. That is, while the external activation device 3 having a “broadcast facility priority value” of 10 transmits a general broadcast (broadcast A) and the wireless transmission / reception device 4 is broadcasting broadcast A, the “broadcast facility priority” A case will be described where the remote control station facility 1 whose “degree value” is 8 transmits a general broadcast (broadcast B) later. 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 8. The I / F unit 9 receives a broadcast request transmitted by the remote control station facility 1 whose “broadcast facility priority value” is 8.

  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 within a predetermined time (step S1). Step S2).

  In step S2, when the I / F unit 9 has not received a broadcast request (step S1no), 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 the “broadcast priority” of the broadcast A has priority over the “broadcast priority” of the broadcast B (step S4).

  In step S4, if the “broadcast priority” of the broadcast A is a priority (step S4 yes), then the calculation unit 8 determines that interrupt broadcasting is not possible, and notifies the control unit 7 of this result (step S7). End processing (end).

  In step S4, if the “broadcast priority” of the broadcast A is not prioritized (step S4no), the arithmetic unit 8 then performs the “broadcast priority” of the broadcast A and the “broadcast priority” of the broadcast B. Are equal to each other (step S5).

  In step S5, if the “broadcast priority” of broadcast A is equal to the “broadcast priority” of broadcast B (step S5yes), then the calculation unit 8 then sets 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 S6).

  In step S5, if the “broadcast priority” of the broadcast A and the “broadcast priority” of the broadcast B are not equal (step S5no), then the arithmetic unit 8 determines that the interrupt broadcast is possible and performs control. The result is transmitted to the unit 7 (step S8), and the process is terminated (end).

  In step S6, if the “broadcasting facility priority” of the broadcasting facility A is the same as or higher than the “broadcasting facility priority” of the broadcasting facility B (broadcasting priority of the broadcasting facility A ≧ broadcasting of the broadcasting facility B) (Step S6yes), the calculation unit 8 determines that the interrupt broadcast is not possible, transmits this result to the control unit 7 (Step S7), and ends the processing (End).

  In step S6, 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 S6no) Next, the calculation unit 8 determines that interrupt broadcasting is possible, and transmits this result to the control unit 7 (step S8), 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 “general” and is equivalent (step S4no, step S5yes). 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, and the “priority value of the broadcast facility” is 10. . 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 8.

  In this case, the calculation unit 8 determines that the “broadcasting facility priority” of the broadcasting facility B is higher than the “broadcasting facility priority” of the broadcasting facility A (step S6no). Further, the calculation unit 8 determines that the interrupt broadcast is possible as a result of the determination of whether or not the interrupt broadcast is possible, and notifies the control unit 7 of the result. The control unit 7 instructs the wireless transmission / reception device 4 to perform broadcasting by interruption as interrupt broadcast 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.

(effect)
According to the present embodiment, while broadcasting a general broadcast transmitted from a certain broadcast facility, another general broadcast transmitted from a broadcast facility having a higher “priority of the broadcast facility” than the broadcast facility is broadcast by interruption. be able to. 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, an embodiment in which each “priority of broadcasting equipment” is variable can be considered. That is, each “broadcasting facility priority” can be changed to a predetermined value after a predetermined time or a predetermined time from a certain time, or each “broadcasting facility priority” Is an embodiment that can be manually or automatically changed to an arbitrary value. Such a configuration allows flexible broadcast control.

(Function)
This embodiment assumes, for example, a broadcast radio system in which an operation console is installed in a government office and a remote control station facility is installed in a guest room. In such a case, in this embodiment, the “broadcasting equipment priority” of the console is higher than the “broadcasting equipment priority” of the remote control station equipment during the daytime, and the “broadcasting equipment priority” of the remote control station equipment at night. The operation mode is such that “priority” is higher than “priority of broadcasting equipment” on the console.

  In addition, this embodiment can be an operation mode in which each “broadcast facility priority” is changed to another value when a failure occurs in the broadcast facility and the master station facility in the broadcast radio system. Here, the control unit 7 included in the console 5 periodically checks whether or not the communication between the broadcasting equipment connected to the console 5 and the console 5 can be normally performed via the I / F unit 9. Suppose you are going. Hereinafter, this confirmation process is referred to as alive monitoring.

  As an example of the implementation method of life and death monitoring, the control unit 7 periodically transmits a signal called a life and death monitoring signal, thereby transmitting a response signal (life and life monitoring response signal) to the broadcasting equipment to be subjected to life and death monitoring. A method for requesting this can be considered.

  The life / death monitoring signal is a signal for determining that the broadcasting facility that has received the life / death monitoring signal transmits a life / death response monitoring signal to the console 5. The life and death monitoring response signal transmitted from the broadcasting facility to the console 5 is communicated with the broadcasting facility from which the control unit 7 included in the console 5 having received the life and death monitoring response signal transmits the life and death monitoring response signal. Is a signal for determining that the operation is normally performed. The life and death monitoring response signal includes “information for identifying broadcasting equipment” (broadcasting equipment name, management number, IP (Internet Protocol) address, MAC (Media Access Control) address, model number) for identifying the broadcasting equipment of the transmission source. , Product name, etc.). Hereinafter, “information that can specify the broadcasting equipment” is referred to as “broadcasting equipment ID”. The “broadcast facility ID (identification)” of each broadcast facility is recorded in the recording unit 6 of the console.

  In this case, the control unit 7 monitors the alive monitoring response signal that the I / F unit 9 receives from the broadcasting facility. In this case, the broadcasting facility has a function to respond when a life / death monitoring signal is received from another device (with a life / death monitoring function) and a device that does not have a function to respond when a life / death monitoring signal is received from another device (life / life monitoring function) None).

  The control unit 7 instructs the I / F unit 9 to transmit a life / death monitoring signal to a broadcasting facility with a life / death monitoring function among the broadcasting facilities connected to the I / F unit 9 (execution request for life / death monitoring). . When the I / F unit 9 receives an execution request for life and death monitoring from the control unit 7, the I / F unit 9 transmits a life and death monitoring signal to a broadcasting facility with a life and death monitoring function among the broadcasting facilities connected to the I / F unit 9. To do. When the life and death monitoring function-equipped broadcasting facility receives a life and death monitoring signal from the I / F unit 9, it transmits a life and death monitoring response signal to the I / F unit 9.

  The control unit 7 included in the console 5 receives the life / death monitoring response signal from the broadcasting facility with the I / F unit 9 within a certain time from the request for performing life / death monitoring, or more than a certain number of times per unit time. If it can be received, it is determined that communication with the target broadcast facility can be performed normally (life and death monitoring success). Further, the control unit 7 records the “broadcast equipment ID” in the life / death monitoring response signal and the information “life monitoring success” in the recording unit 6 in association with each other.

  The control unit 7 included in the console 5 has a fixed number of times per unit time when the life / death monitoring response signal from the broadcasting facility with the I / F unit 9 cannot be received within a certain time from the execution request for life / death monitoring. If it cannot be received, it is determined that communication with the target broadcasting facility cannot be performed normally (life monitoring failure). Furthermore, the control unit 7 associates the “broadcast equipment ID” in the life and death monitoring response signal with the information “life and death monitoring failure” and records them in the recording unit 6 as “broadcast equipment that has failed life and death monitoring”. At this time, the control unit 7 determines that a failure has occurred in the target broadcast facility. Furthermore, the control unit 7 lowers the “broadcast facility priority” of the target broadcast facility recorded in the recording unit 6. Thereby, when a failure occurs in the broadcasting equipment and the master station equipment in the broadcast radio system, each “broadcasting equipment priority” can be automatically changed to another value.

  As described above, life and death monitoring is periodically repeated. However, when a broadcasting facility determined to be life and death monitoring failure is later determined to be life and death monitoring success, the control unit 7 sets the target “ Delete information on "broadcasting equipment that failed to be alive monitored". At this time, it is a parameter on the system whether the "broadcasting equipment priority" changed when it is determined that life and death monitoring has failed is automatically restored to the original value or not automatically restored to the original value. (Setting items, system initialization file, etc.) can be set.

  As another example of a method for performing alive monitoring, a method in which a broadcasting facility periodically transmits a alive monitoring response signal to the console 5 can be considered.

  In addition, in this embodiment, only when the broadcasting facility makes a broadcast request under a specific condition, the “priority of the broadcasting facility” of the broadcasting facility that requested the broadcasting and other broadcasting facilities is automatically changed to another value. It can be set as the operation mode. In this case, the control unit 7 monitors a signal that the I / F unit 9 receives from the broadcasting facility. In this case, the automatic starter 2 is a nationwide instantaneous warning system (J-ALERT) receiver, and has a function of automatically requesting broadcasts for various information such as guerrilla attack information, weather information, and disaster information. In addition, the automatic starter 2 that is a receiver of the national instantaneous warning system (J-ALERT), when requested to broadcast, sends to the I / F unit 9 the type of broadcast content (national protection related information, emergency earthquake warning, volcano It has a function of transmitting number information called “report number” indicating an eruption warning, weather information, etc.) as part of a broadcast request signal. It is assumed that the “report number” and the type of broadcast content indicated by the report number are recorded in the recording unit 6 in advance. Also, in this case, the external activation device 3 is a tsunami warning device, and automatically activates broadcasting when there is a high possibility that a tsunami will occur or after a tsunami has occurred.

  As shown below, when a broadcast request for the earthquake early warning is made from the automatic starter 2 which is a receiver of the Japan Instantaneous Warning System (J-ALERT), the master station equipment is the “priority of broadcasting equipment” of the tsunami warning device. Increase the degree automatically.

  The I / F unit 9 receives a broadcast request from the automatic activation device 2. The control unit 7 confirms that the I / F unit 9 has received a broadcast request from the automatic activation device 2. Next, the control unit 7 acquires the “report number” included in the broadcast request signal received by the I / F unit 9 from the automatic activation device 2 and sends it to the calculation unit 8, and the “report number” is received from the recording unit 6. Information on the type of broadcast content shown is acquired and sent to the calculation unit 8. The calculation unit 8 compares whether or not the “report number” received from the automatic activation device 2 matches the report number indicating the contents related to the earthquake early warning. As a result of the comparison, when the “report number” received from the automatic startup device 2 matches the report number indicating the contents related to the earthquake early warning, the calculation unit 8 instructs the control unit 7 to “receive from the automatic startup device 2”. Information indicating that the report number is the broadcast number for earthquake early warning is sent. When the control unit 7 obtains information from the calculation unit 8 that “the notification number received from the automatic activation device 2 is the broadcast number related to the earthquake early warning”, the “7” of the tsunami warning device recorded in the recording unit 6 The priority of “broadcasting equipment” is increased, and the wireless transmission / reception apparatus is instructed to perform broadcasting based on the broadcast request received from the automatic activation apparatus 2. When the “report number” received from the automatic activation device 2 does not match the report number indicating the contents related to the emergency earthquake warning as a result of the comparison in the calculation unit 8, the calculation unit 8 instructs the control unit 7 to “ Information indicating that the report number received from the automatic activation device 2 is not a broadcast number related to the earthquake early warning is sent. When the control unit 7 obtains information from the calculation unit 8 that “the report number received from the automatic starter 2 is not a broadcast number related to the earthquake early warning”, the tsunami warning recorded in the recording unit 6 The radio transmission / reception apparatus is instructed to perform broadcasting based on the broadcast request received from the automatic activation apparatus 2 without changing the “broadcast facility priority” of the apparatus.

  As described above, when the automatic activation device 2 that is a national instantaneous warning system (J-ALERT) receiver makes a broadcast request relating to the emergency earthquake warning, the “3” of the external activation device 3 that is a tsunami warning device is used. "Broadcasting facility priority" can be automatically increased. As a result, the tsunami in which the external activation device 3 as a tsunami warning device makes a broadcast request while the emergency broadcast related to the earthquake early warning that makes a broadcast request from the automatic activation device 2 that is a national instantaneous warning system (J-ALERT) receiver is being broadcast. It becomes possible to broadcast emergency broadcasts on interruptions.

  In this embodiment, a value larger than 0 is set in advance as the “broadcast equipment priority value” of each broadcasting equipment in the system, and “broadcasting equipment priority” is set for any broadcasting equipment later. If the “value” is manually set to 0, an emergency broadcast from the broadcasting facility can always be broadcast by interruption.

  Furthermore, if the “priority value of the broadcasting equipment” is returned to the original value or set to a value larger than 0 at another arbitrary timing, the broadcasting is always interrupted in the same procedure for another arbitrary broadcasting equipment. Can be performed. On the other hand, if the “priority value of broadcasting equipment” is not changed to 0, the broadcasting equipment can broadcast without interruption.

(effect)
According to the present embodiment, it is possible to operate according to a time zone in which interrupt broadcasting is performed from the console during the day and interrupt broadcasting is performed from the remote control station facility at night.

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 7 changes the “broadcasting equipment priority” based on information about the surrounding environment acquired from various sensors.

  For example, each of the console 5 and the remote control station equipment 7 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.
