Disaster broadcasting is sent through the broadcasting device 71. In addition, the disaster broadcasting system 30 may transmit a disaster state and an operating state of the system to the manager terminal 10.

The sensor device 23 is a device for collecting disaster-related data, and refers to sensors for collecting various disaster-related states such as environmental monitoring sensors and rainfall sensors. The sensor device 23 also includes a sensor network USN. Data collected by the sensor device 23 is transmitted to the disaster broadcasting system 30 through the network 22. The network 22 includes both a wired network such as the Internet, a dedicated network and a wireless communication network such as CDMA.

The disaster broadcasting apparatus 71 is an apparatus for sending out disaster broadcasting, and refers to an audio output apparatus such as a speaker for outputting an audio signal. The disaster broadcasting system 30 periodically broadcasts a disaster broadcast such as a disaster state or action point when a disaster occurs, so that people can prepare for or cope with a disaster. Since the disaster broadcasting device 71 operates periodically, unlike other disaster equipment 72, the power source is periodically used.

In addition, the disaster broadcasting apparatus 71 includes a sound source IC and a recordable IC, so that the voice or the recorded voice embedded in the sound source IC can be periodically broadcasted or singly. The disaster broadcasting apparatus 71 includes a speaker 73, an audio amplifier 74, and the like.

Disaster equipment 72 refers to other devices for managing disasters, such as CCTV, remote monitoring equipment. Disaster equipment 72 refers to devices that are always operated to consume power. That is, the disaster broadcasting apparatus 71 consumes power periodically, while the disaster equipment 72 always consumes power. The disaster broadcasting system 30 may also be included in one disaster equipment 72 in the sense of a disaster-related device that must be operated at all times.

That is, in the following, the disaster equipment 72 is used as a device that consumes power at all times for disaster management. In addition, the disaster broadcasting device 71 is used as a device that operates periodically for disaster management. Therefore, the disaster-related equipment may be classified according to whether the power consumption is constant or periodic as described above, but for the convenience of description, the term disaster equipment or disaster broadcasting apparatus is used herein.

The battery 60 is a rechargeable secondary battery. Disaster-related equipment uses a commercial power source, but uses a rechargeable battery that can be recharged in the event of a power plant loss or difficult installation. On the other hand, the battery 65 is charged by a commercial power source (not shown) or by a solar cell 60 (cell).

The battery management device 40 measures the remaining amount of the battery 60 by monitoring the secondary battery charging and discharging, or consumed by disaster-related equipment (disaster broadcasting device or disaster equipment) under the control of the disaster broadcasting system 30. Shut off power.

To this end, the battery management device 40 has a built-in circuit and an embedded computer (microcomputer) for checking the charge / discharge state of the secondary battery and the battery use environment and calculating a DB to calculate an accurate battery level and displaying this value. Equipped with a display device.

The disaster broadcasting system 30 receives the remaining amount of the battery 60 from the battery management device 40 and informs the administrator of the remaining battery level according to the remaining battery amount, or the disaster-related equipment (disaster broadcasting device or disaster equipment) used Control power consumption. In particular, the disaster broadcasting system 30 cuts off the power of the disaster equipment through the battery management device 40 if necessary.

The battery management device 40 or the disaster broadcasting system 30 is built using a small embedded computer (computer running embedded Linux, WINDOWS CE and RTOS) using a microcomputer. The battery management apparatus 40 or the disaster broadcasting system 30 may be implemented as one integrated system.

As another embodiment, the battery management device 40 may have a built-in CDMA modem, and in this case, the remaining amount of information may be stored using a CDMA modem built in itself without using a wired or wireless communication medium built in the disaster broadcasting system 30. It can be delivered to the manager terminal (10).

The manager terminal 10 is a computing terminal used by the disaster manager, and is a mobile terminal that a manager can carry or carry, such as a mobile phone, a PDA, and a notebook computer. The disaster broadcasting system 30 or the battery management apparatus 40 transmits the disaster state and the state of the disaster equipment to the manager terminal 10 through the wireless communication network 21. At this time, the wireless communication network 21 uses CDMA, WI-FI, binary CDMA, ZIGBEE, VHF, satellite packet communication, and the like. Preferably, the wireless communication medium uses CDMA, binary CDMA, satellite packet communication. In particular, when the manager terminal 10 is a mobile phone, information is transmitted using a text message.

For example, if the disaster broadcasting system does not have a built-in wireless CDMA modem, the remaining amount information may be transmitted to the manager terminal 10 using a LAN, WIFI, or other wired or wireless communication medium embedded in the disaster broadcasting system.

In addition, the manager may directly access the disaster broadcasting system 30 through the manager terminal 10 to control the disaster broadcasting. In particular, the manager can send a single-disaster broadcast that makes a call through the manager terminal 10 and broadcasts directly by voice.

On the other hand, the manager terminal 10 can be applied to a wired terminal, such as a wired telephone, a PC. That is, any terminal that can send and receive messages can be applied.

On the other hand, the disaster broadcasting system 30 has a circuit for controlling microphone input circuits, CDMA and wired and wireless communication media therein, and interfaces with a sensor network, external audio amplifier control, broadcast status monitoring, and disaster monitoring equipment (CCTV). Etc.) and interfaces.

In addition, the disaster broadcasting system 30 provides a manual broadcast function that allows the administrator to broadcast using a microphone. In addition, the disaster broadcasting system 30 may be connected to the sensor network and automatically reproduces and broadcasts the built-in sound source when an alarm is required according to the sensor value.

In addition, the disaster broadcasting system 30 is equipped with digital data communication means such as RS-232 and ZIGBEE to interface with the battery management device 40 and other disaster-related systems.

Next, a configuration of a disaster broadcasting facility according to an embodiment of the present invention will be described with reference to FIG. 2.

As shown in Figure 2a, the disaster broadcasting facility 80 according to an embodiment of the present invention is a stand-alone pole with a surveillance camera 72, a speaker 73, a satellite antenna 83, a solar panel 65, etc. And may be implemented at 81.

That is, the disaster broadcasting facility 80 is composed of a support 82 and a stand-alone pole 81 that can be installed in an area where a disaster alert such as a river bank, a seawall, a marina, etc. is most needed, and monitors the stand-alone pole 81. A camera 72, a speaker 73, a solar panel 65, and the like are provided, and in particular, it is composed of a housing 50 in which the disaster broadcasting system 30 and the battery management device 40 can be installed.

As shown in Figure 2b, the housing 50 is configured in a rack form to mount the disaster broadcasting system 30 and the battery management device (40). Preferably enclosure 50 uses a 3U type of 19-inch rack.

In addition, the enclosure 50 may be equipped with an audio amplifier 74 for broadcasting voice through the speaker 73. Therefore, the speaker 73, the audio amplifier 74, etc. are comprised, and the disaster broadcasting apparatus 71 is formed. In addition, a battery 60 or the like is built in the housing 50. The built-in battery is preferably used 12V 100AH capacity.

Moreover, the control apparatus 75 etc. which control the solar cell 65 are also contained in the enclosure 50.

Enclosure 50 shown in Figure 2b is preferably in a small form so that it can be mounted to the stand-alone pole 81 of Figure 2a. In addition, the housing 50 is preferably made of a stainless steel waterproof.

On the other hand, as another embodiment, instead of being mounted directly to the stand-alone disaster broadcasting facility 80, it may be installed by providing a separate space. In this case, the disaster broadcasting system 30 and the battery management device 40 can be more high-performance and large capacity system configuration.

Next, the configuration of the disaster broadcasting system according to an embodiment of the present invention will be described with reference to FIG. 3.

As shown in FIG. 3, the disaster broadcasting system 30 according to an embodiment of the present invention includes a disaster broadcasting unit 31, a power remaining input unit 32, a power consumption measuring unit 33, and a remaining time estimating unit 34. , And notification means (35). In addition, the power cut-off unit 36 or the disaster broadcast limiting unit 37 may be configured to further include a disaster broadcast receiving unit 38. It further comprises a memory 39 for storing data.

The disaster broadcasting unit 31 broadcasts disaster broadcasting periodically according to a broadcasting cycle. The disaster broadcasting unit 31 may adjust a broadcasting interval by setting a broadcasting cycle. For example, if the broadcast period is set to 10 minutes, disaster broadcasting is broadcast every 10 minutes, and if it is set to 30 minutes, disaster broadcasting is broadcast every 30 minutes.

On the other hand, as shown in Figure 3, disaster broadcasting can be prepared by broadcasting the same content in different lengths. All three broadcast phrases in FIG. 3 are contents of the same disaster broadcast. However, FIG. 3A is a broadcast phrase that describes the contents of the same disaster broadcast in detail in a long time, and FIG. 3B is a broadcast phrase that is shortened to a respectful expression. Finally, Figure 3c is a disaster broadcasting summarizing only the essential content.

When the length (type of length) of the disaster broadcast is determined, the disaster broadcasting unit 31 sends the disaster broadcast to the broadcast phrase of the corresponding length.

The remaining power input unit 32 receives the remaining battery level from the battery management device 40. The battery manager 40 detects the battery output voltage and calculates the remaining amount of the battery. In addition, the remaining amount of the battery is more accurately calculated by additionally detecting and compensating the battery temperature, the load charge amount, and the like. Since the technique for detecting the remaining battery level is well known as shown in the prior art 1, a detailed description thereof will be omitted.

The power consumption measuring unit 33 measures the power consumption of the disaster broadcasting 71 or the disaster equipment 72. The power consumption of the disaster broadcasting refers to the power consumption of the disaster broadcasting apparatus 71, and when used in this sense, the same reference numeral 71 is also given to the disaster broadcasting.

The power consumption measuring unit 33 measures and stores the power consumption of the disaster broadcasting 71 or the disaster equipment 72 in advance, or uses the power disaster broadcasting 71 or the disaster equipment 72 in real time. Accumulate the power and divide the accumulated power by the usage time to find the average power consumption.

The remaining time estimator 34 calculates an estimated time that can be operated with the current battery level using the remaining battery power and the power consumption of the disaster-related equipment. In this case, two embodiments in which only the disaster broadcasting 71 is used and the disaster broadcasting 71 and other disaster equipment 72 together are described. As described above, the disaster broadcast 71 is operated according to the broadcast cycle, the disaster equipment 72 is distinguished in that it is always operated.

A first embodiment using only disaster broadcasting will be described. The remaining time estimator 34 calculates an estimated number of broadcasts and a broadcast time of the disaster broadcast by using the remaining battery power and power consumption of the disaster broadcast.

The remaining time estimator 34 obtains the estimated total remaining broadcast time of the disaster broadcast by dividing the remaining battery power by the power consumption of the disaster broadcast, and obtains the estimated remaining broadcast frequency by dividing the estimated total broadcast time by the one time broadcast time. Power consumption of disaster broadcasting means power used per hour. Therefore, dividing the remaining battery power by the power consumption of the disaster broadcast calculates the total broadcast time. Divide this by one broadcast time to find the number of broadcasts.

Next, a second embodiment using the disaster broadcasting 71 and the disaster equipment 72 together will be described. The remaining time estimator 34 calculates an estimated remaining operating time of the disaster broadcasting and the disaster equipment by using the remaining battery power and the power consumption of the disaster broadcasting 71 and the disaster equipment 72.

The remaining time estimating unit 34 calculates an expected remaining operating time Δt _R by the following Equation 1.

[Equation 1]

However, P _B is the battery level and W _C and W _E are the power consumption of disaster broadcasting and disaster equipment, respectively. Δt _C is one broadcast time and T _C is a broadcast period.

The remaining operating time can be obtained by dividing the remaining battery power by the total power consumption per hour of the disaster broadcasting 71 and the disaster equipment 72. However, since the disaster broadcast 71 is broadcasted periodically according to the broadcast cycle, in order to obtain the power consumption per hour, it is necessary to multiply the power consumption W _C of the disaster broadcast by the value divided by one broadcast time by the broadcast cycle.

In addition, the remaining time estimator 34 calculates the estimated remaining broadcast times by dividing the estimated remaining operating time Δt _R by one broadcast time Δt _C.

The notification unit 35 transmits the estimated remaining broadcast times and broadcast times, or the estimated remaining operating times to the manager terminal 10.

The power cut-off unit 36 cuts off the power of the disaster equipment according to the remaining battery capacity, and sequentially cuts off the power of the disaster equipment. At this time, the power cutoff unit 36 cuts off the power of the disaster equipment through the battery management device 40.

In particular, the power cut-off unit 36 classifies the remaining level according to the remaining battery level, determines the level of disaster equipment to be operated in each remaining level, obtains the remaining level belonging to the measured battery remaining level, and the disaster equipment rating of the obtained remaining level Isolate lower grade disaster equipment.

As shown in FIG. 4, the remaining battery level may be divided into a plurality of stages. For example, if the remaining battery amount is 80-100%, it is divided into one step, and if it is 40-60%, it is divided into three steps. In addition, the battery level is divided into five levels of less than 10%.

And categorize disaster equipment by importance. For example, even with the same type of CCTV cameras, if there is a high likelihood of collapse of the dike in case of heavy rain, the digging CCTV is a very important disaster and should be monitored at all times. On the other hand, CCTV installed on a general road to check the rain on the road is relatively less important. Therefore, if the battery is very low, and the power of one of the two CCTV must be cut off, it is preferable to cut off the power of the CCTV installed on the road.

Therefore, the grade of CCTV cameras installed on the banks is set high, and the grade of CCTV cameras installed on the road is set low. Disaster equipment classes are all set in advance.

In the example of FIG. 4, when the battery is initially fully charged, it supplies power to at least five grades, i.e. all disaster equipment. When the battery is consumed and falls to 70%, the remaining level is two levels and the level of disaster equipment is level 4, so it supplies power to disaster equipment above level 4 and cuts off the power of level 5 disaster equipment.

In this way, if the battery level is 30%, the remaining battery level is 4 stages, and the disaster equipment class is Class 2, so it supplies power to disaster equipments of class 2 or higher, and supplies power to all disaster equipments of class 3 or lower. Block it.

The disaster broadcasting limiter 37 adjusts the broadcast time of the disaster broadcasting according to the remaining battery capacity. In particular, the disaster broadcasting limiter 37 classifies the remaining level according to the remaining battery level, and determines the broadcast period in each remaining level, but the longer the remaining period, the longer the broadcast period to obtain the remaining level belonging to the measured battery remaining, Broadcast periodically according to the remaining broadcast period.

As described above, the remaining level is classified according to the remaining battery level. And set the broadcasting cycle of the disaster broadcasting corresponding to each remaining level. As in the example of FIG. 4, steps 1 and 2 are set to 10 minutes, steps 3 and 4 are 30 minutes, and step 5 is set to 60 minutes. For example, when the battery is fully charged at first, the broadcast cycle is sent out every 10 minutes since it is a first step. That is, export often. However, if the battery level drops to 30%, the battery level is 4 levels, so the broadcast cycle is increased to 30 minutes. As the broadcast cycle increases, the number of broadcasts per hour decreases, thus reducing battery consumption.

In addition, the disaster broadcasting limiting unit 37 classifies remaining levels according to the remaining battery level, and determines a disaster broadcasting having a different broadcasting time according to the remaining level, but sets a disaster broadcasting having a shorter broadcasting time as the remaining amount falls, and thus belongs to the measured battery remaining amount. Find the remaining level, and broadcast the disaster broadcast belonging to the obtained remaining level.

The remaining levels are classified according to the remaining battery level and the length of the broadcasting library of disaster broadcasting corresponding to each remaining level is set. As seen in the example of FIG. 3 above, the length of the broadcast phrase can be divided into (a), (b), (c). That is, (a) the broadcast phrase is composed of detailed and very long sentences and has a long broadcast time. In contrast, (c) the broadcast text is very short and is broadcast for a short time. Therefore, in case of broadcasting by (c) broadcasting phrase, battery consumption can be considerably reduced.

As in the example of Figure 4, steps 1 and 2 are set to (a) the broadcast phrase, steps 3 and 4 are (b) broadcast phrase, step 5 is set to (c) broadcast phrase. For example, if the battery is fully charged at first, it is a first step, so the detailed broadcast phrase (a) is sent out. However, if the battery level drops to 30%, the battery level is 4 levels, so the broadcast phrase is sent to the shortest (c). As the broadcast time is shortened, battery consumption can be reduced.

On the other hand, the broadcast phrases of disaster broadcasting can be mixed and exported. In other words, in step 3, (b) phrases and (c) phrases are intersected and in step 4, (b) phrases (c) three times per sentence. In other words, if you continuously send a short broadcast phrase is not easy for people to understand, sometimes you can send a long broadcast phrase.

In addition, the disaster broadcast receiver 38 receives a disaster broadcast from the administrator terminal to broadcast through the disaster broadcast unit. That is, the disaster broadcasting system 30 receives the administrator's voice information through the manager terminal 10 during an emergency disaster as well as a periodic broadcasting function and broadcasts in real time. Disaster broadcasting by the administrator is done only once. At this time, a microphone, a mobile phone, or other wired or wireless communication medium is used as the manager terminal 10. That is, the manager can make a voice broadcast by dialing a wireless CDMA modem built into the system at a remote location through the manager terminal 10.

The method of the present invention described above can be implemented with a program system on a computer device. That is, the disaster broadcasting system may be configured as a program and installed and executed in a computer device. A program installed on a computer device may operate as one system.

Meanwhile, as another embodiment, the disaster broadcasting system may be implemented by an electronic circuit such as an ASIC (on-demand semiconductor) in addition to being operated by a general purpose computer. Other possible forms may be implemented.

In addition, embodiments of the present invention include computer-readable media containing program instructions for performing various computer-implemented operations. The computer readable medium may include program instructions, local data files, local data structures, etc. alone or in combination. The media may be those specially designed and constructed for the present invention, or they may be of the kind well-known and available to those having skill in the computer software arts. Examples of computer-readable recording media include magnetic media such as hard disks, floppy disks, and magnetic tape, optical recording media such as CD-ROMs, DVDs, magnetic-optical media such as floppy disks, and ROM, RAM, flash memory, and the like. Hardware devices specifically configured to store and execute the same program instructions are included. Examples of program instructions include not only machine code generated by a compiler, but also high-level language code that can be executed by a computer using an interpreter or the like.

As mentioned above, although the invention made by this inventor was demonstrated concretely according to the Example, this invention is not limited to an Example and can be variously changed in the range which does not deviate from the summary.

The present invention can be applied to the development of a disaster broadcasting system that notifies the estimated number of remaining broadcasts and the broadcast time of the disaster broadcast or adjusts the power consumption of the disaster broadcast according to the remaining amount of battery supplying the power of the disaster broadcast.
