Description

  The present invention relates to a collapsed house information notification system, and more particularly, to a collapsed house information notification system mainly intended for lifesaving, assuming a situation in which a mobile phone network or the Internet network cannot be used.

When disasters such as earthquakes, landslides, avalanches, and cliff collapses occur, the first thing that is done is to save the lives of the victims. It is important to know the detailed situation of the presence and number of victims after the arrival of the team.
FIG. 6 is an image diagram showing an example of a conventional notification system when a disaster occurs. In the system shown in this example, for example, a landslide sensor (disaster detection sensor) 60 is installed on a cliff or an inclined surface that is recognized as having a high risk of collapse, and the sensor output signal is transmitted to a communication line or a mobile phone unit. , Notify the nearest fire and municipal disaster prevention management center 62 through the infrastructure (infrastructure) 61 such as a commercial wireless communication device, and the management center that receives this notifies the local residents to evacuate and warn It was like that. For example, Patent Document 1 discloses an example of means using an optical fiber as means for detecting an abnormality such as debris collapse at this time, and can be referred to.
The purpose of such a system is to quickly detect signs of disasters and prevent human damage through evacuation guidance for local residents.
JP 2003-232043 A

However, even if the conventional method described above has the effect of predicting the occurrence of a disaster and preventing the occurrence of a victim by evacuation guidance, in the event of an actual disaster, it is not effective for relief of the victim. There wasn't. In addition, when a local communication facility is instantaneously damaged as in a direct earthquake, the means for notifying the situation is often lost, so the purpose of evacuation guidance for local residents is often not achieved.
For example, in a large-scale disaster that occurred in the Hanshin area or a disaster such as the Chuetsu earthquake, even if the occurrence of the disaster is known, in the situation where many buildings collapsed over a wide area, which position in which building In addition, there is no information on how many people are buried, and there are cases where there is no way to do it before the looming fire.
It is said that the survival rate of rescued victims will drop to less than 50% if the period from disaster occurrence to rescue exceeds 15 days, and will be only 1% if the period exceeds 20 days. Yes (Disaster information in the Hanshin area).
In this situation, if communication (local community) of local residents is activated and detailed information exchange between local residents is carried out on a regular basis, the presence or absence of a single person living at home in the event of a disaster or the room The position can be estimated, which is a clue for quick rescue. However, in today's society, the growing awareness of personal privacy protection is adding to the diminishing local community.
The present invention has been made in view of such problems at the time of a disaster, and it is possible to determine the possibility that a victim exists in a house collapsed at the time of a disaster, The purpose is to provide a collapsed house information notification system in which various information necessary for victim relief, such as whether there is a high possibility of being present, can be obtained.

In addition, if the indoor transmitter / receiver is equipped with a battery as an emergency power supply, communication with external communication devices such as a simple base station device or a repeater device is possible even if the mobile phone or the Internet is disconnected due to a disaster. .

Hereinafter, the present invention will be described in detail with reference to embodiments shown in the drawings. However, the components, types, combinations, shapes, relative arrangements, and the like described in this embodiment are merely illustrative examples and not intended to limit the scope of the present invention only unless otherwise specified. . In addition, the same parts and the same matters as those already described are denoted by the same reference numerals and numbers, and redundant description is omitted.
FIG. 1 is a system outline diagram showing an example of a collapsed house information notification system according to the present invention. In FIG. 1, reference numeral 1 denotes a monitoring target house, in which a memory device that stores resident information such as an address, a householder's name, the number of residents, and fixed information such as a layout of the house, temperature, time, etc. Among them, a control unit including a sensor or the like that generates necessary information is provided, and an indoor transmission / reception device 2 that can communicate with an external communication device described later is provided. This indoor transmitter / receiver is preferably capable of communicating with a nearby external communication device, etc. even if the public communication line is interrupted in the event of a disaster. Similar to a wireless communication device would be suitable. At the same time, it is possible to use a function capable of accessing an external communication means such as the Internet via a mobile phone line or a wireless LAN. Also, in preparation for the damage of commercial power supply in the event of a disaster, a rechargeable battery is added, and while the commercial power supply (AC power supply) is normally supplied, always keep a full charge state by a floating charging method etc. Keep it.
Furthermore, the monitoring target house 1 includes a crisis sensor 3 including a house collapse sensor that detects the collapse or breakage of a required part of the house and supplies it to the indoor transmission / reception apparatus, etc. 2 and an external device 4 such as a resident room sensor means for supplying to the housing 2. Here, the crisis sensor 3 is, for example, a strain detection sensor laid in a direct part of a house pillar or beam and detecting deformation of the pillar or beam when the house collapses due to an earthquake or the like, or A vertical sensor is attached to the pillar, and various things such as detecting the collapse of the house depending on the degree of inclination of the pillar, and detecting the deformation of the house using the optical fiber disclosed in Patent Document 1, can be selected as appropriate. be able to.

Further, as the resident room sensor means (external device) 4 for obtaining the occupant status information of the resident, for example, information on indoor lamps that are lit (or lit) when a disaster occurs, opening / closing records of refrigerators, etc. One that collects and records usage status information from home appliances and the like that can be information indicating the possibility that the resident is in the room is considered. Furthermore, as a room sensor means, a resident is brought with a non-contact response device including an IC chip, a question signal is sent to the non-contact response device, and a room detection terminal device for detecting the response signal is provided in each room. It may be configured to be arranged. This non-contact response device also has a non-power supply system, and the room detection terminal device for detecting a response signal is newly provided by transmitting and receiving signals through a commercial power line (AC power line) in the house. It would not be necessary to lay a simple signal line.
Information supplied from these devices and sensors is stored in the memory of the in-house transmission / reception device 2, and information recording / updating is usually performed as necessary. When it is determined that the house has collapsed based on the information from the crisis sensor 3, the date and time information, the fluctuation information such as the occupant's room information at that time, and the like are stored, and information from an external communication device to be described later is stored. When the transmission command is received, the fixed information and the fluctuation information are notified.
If a house collapses due to an earthquake, etc., the ambulance team will rush to rescue. At that time, the rescue team carries the simple base station device 5 as an external communication device or is mounted on the vehicle. It shall be. This simple base station apparatus 5 can communicate with the above-described indoor transmission / reception apparatus 2 instead of the original base station apparatus, and serves as a base station or a repeater apparatus that gives control instructions to other indoor transmission / reception apparatuses. If possible, it is preferable to provide a relatively large display device (display) 6 so as to be convenient for rescue operations.

A specific example of communication operation in the above configuration will be described.
FIG. 2 is a schematic diagram showing a state of use frequency allocation to the above-described indoor transmission / reception apparatus 2, and taking into consideration the scale of the disaster (range) at the time of the disaster or the disaster area in advance. Then, frequency allocation is performed as appropriate. If only one frequency is assigned to the indoor transmitting / receiving device 2, the frequency arrangement shown in FIG. 2 is determined in advance. As shown in FIG. 2, when the transmission output of the indoor transmission / reception apparatus 2 is small, for example, when a radius of about 100 m is a communication range, the target area is divided into several regions (cells) having a radius of about 100 m and adjacent to each other. Cells to be assigned are assigned different frequencies. Since these means are used as means for effectively using a small number of frequencies and channels in a cellular radio communication system such as a normal cellular phone, no special explanation will be necessary.

FIG. 3 is a sequence diagram illustrating an example of a specific information notification method between the indoor transmitting / receiving device 2 and the simple base station device (external communication device) 5 in the configuration described above. Also in this example, it is assumed that necessary fixed information and fluctuation information are stored in the memory in the indoor transmission / reception device 2 in the collapsed house as described above, and the indoor transmission / reception device 2 detects the collapse of the house from the crisis sensor 3. When the information shown is supplied, it shifts to a standby state waiting for reception of a command signal (including an Idle signal) from the simple base station device (external communication device) 5.
In this state, the base station status notification (Idle) indicating that the data line is vacant (communicable) via the control channel (control CH) from the simple base station apparatus 5 carried by the rescue team or the like arriving at the site. ) A signal is transmitted (S1). When receiving the Idle signal from the simple base station 5, the indoor transmission / reception apparatus 2 transmits a connection request signal to the simple base station apparatus (base station) 5 via the control channel (S2). When the connection confirmation signal is returned from the simple base station apparatus 5 in response to this request (S3), the indoor transmitting / receiving apparatus 2 uses the simple base station apparatus to store the information stored in the memory as described above. 5 (S5). When the simple base station apparatus receives a connection request signal from the indoor transmission / reception apparatus 2 and there is no free data channel (data CH), the simple base station apparatus 5 is a mobile station including other indoor transmission / reception apparatuses. By transmitting a Busy signal via the control channel to the (slave station), the other slave stations are instructed to suspend or wait for communication, and communicate with the in-house transmitter / receiver 2 of a highly urgent collapsed house. (S4). It should be noted that as many data CHs as possible can be secured.

The indoor transmitter / receiver 2 transmits the resident room information stored via the designated data CH, the floor plan of the house, and the information such as the number of residents and the resident composition to the simplified base station device 5 (S5), A connection end request signal is transmitted (S6). Receiving this, the simple base station device 5 displays it on the attached display 6 to inform the rescue team in detail of the situation, and transmits a connection end signal to the indoor transmitting / receiving device 2 (S7). Receiving the end signal, the indoor transmission / reception apparatus 2 determines that the data transmitted from the own station has reached the simple base station apparatus 5, ends the connection, and shifts to the start / stop state (S8). If the simple base station device 5 is transmitting a Busy signal at that time, the simple base station device 5 transmits an Idle signal via the control CH, and the data CH is available to other slave stations (communicable). (S9).
By adopting the trunking system as described above, it is possible to perform efficient communication operation without causing communication collision between a plurality of indoor transmitting / receiving apparatuses.
The indoor transmission / reception device 2 that has once transmitted necessary information to the simple base station device 5 stops operating for a certain period of time, and again receives a command from the simple base station device 5 (a command signal including an Idle signal or a selective call signal). ). By repeating such an operation at regular intervals, power consumption is reduced to a minimum, and information is transmitted over a long period of time using limited battery power. For example, if a part of the information collection function of the indoor system is still alive after the collapse and the information about the victim is updated, the information can be collected in real time and used for rescue. Is possible. In order to further reduce power consumption, it is also possible to adopt a battery-save method based on frame synchronization in which the reception frame (timing) at the time of standby is determined in advance and the remaining functions are kept to the minimum necessary functions. I will.

FIG. 4 is a state transition diagram of the indoor transceiver device 2 that performs the above operation. In FIG. 4, the “standby state” is a state of waiting for an Idle signal transmitted from the simple base station apparatus 5 as described above. When the Idle signal is received, the connection to the simple base station apparatus 5 is established. Make a request. Note that while the Busy signal is transmitted from the simple base station device 5, the standby state remains, so that power is turned on at least in the receiving device portion.
In FIG. 4, “operating state” is an operation of communicating with the simplified base station apparatus 5 and transmitting stored information. Therefore, this is an operation that requires power supply to the transmitter and consumes the most current.

There are two possible states for the “stop state” in FIG. If the house is not collapsed and the commercial power supply is operating normally (normally “stopped state”), information from the sensor is detected periodically from each sensor or whenever a new state is detected. The necessary information is stored in the memory while performing the process of detecting the presence or absence of the house collapse, the occupant's room information, and the operation status of the external device. Also, once the house collapses, it shifts to the above “standby state” based on the information from the crisis sensor, and waits for the Idle signal from the simple base station apparatus. And after transmitting required information to the simple base station apparatus 5, it will be in the "stop state" in a battery drive state. At this time, in order to reduce current consumption as much as possible, the power supply to all circuits is cut off except for a portion necessary for maintaining the timer function. When the timer detects that a certain period of time has elapsed, it transitions to the “standby state” again. When the predetermined time is measured by the timer, it transitions to the “stop state” again, and the same operation is performed in a preset cycle. Repeat. Even when the commercial power supply is detected to be alive even in the “stop state” after the house collapses, it is possible to perform the same operation as in the “stop state” at the normal time.
Comparing the current consumption in the above three states, the current consumption generally increases in the order of “stop state” <“standby state” <“operation state”.

  Although FIG. 5 is not limited to this example, FIG. 5 illustrates an example of a collapsed house information screen displayed on the display 6 provided in the above-described simple base station apparatus. For example, the area block previously assigned to each house Number, address, head of household (name), number of family members, and temperature (temperature) are displayed. In addition to the number of families, adding information such as age, health status such as difficulty walking, necessity of nursing care, home doctor, etc. may be useful for health management after rescue.

Although the embodiments of the present invention have been described above, the present invention is not limited to these examples, and various modifications are possible. For example, the case where the simple base station apparatus 5 moves to the site and functions as a temporary base station apparatus when a disaster occurs has been described. However, the present invention is applied to a disaster-prone area or an area where a large-scale earthquake is expected. For this implementation, a fixed base station apparatus may be installed, or an existing base station apparatus may be used.
In addition, it may be useful for grasping the damage situation to provide various sensors such as a gas generation sensor, a fire generation sensor, a water flow sensor, and a sediment flow sensor as crisis sensor means set in the house. Furthermore, if it is possible to collect ecological information of residents confined in collapsed houses, it will be more useful for rescue operations. Therefore, in a situation where the victim resident has freedom, it is possible to make it possible to talk directly with the external communication device from the microphone of the indoor transmitting / receiving device 2 or the like. In that case, since it is assumed that the resident is unfamiliar with the operation of the wireless device, it is also possible to configure so that the transmission / reception operation can be performed by remote control from the simple base station device 5. In addition, assuming that the freedom of movement is confined in a collapsed house, the resident carries a small wireless handset that can communicate with the indoor transmitting / receiving device, and externally through the indoor transmitting / receiving device as necessary. It may be configured to be able to talk to the communication device. Furthermore, the small wireless transmitter / receiver is incorporated in an article worn by a resident such as a bracelet, a ring, a necklace, or a pendant, and further detects a biological information such as a pulse and a body temperature. It may be possible to transmit the ecological information to the indoor transmission / reception device 2 by providing.
Moreover, it is also possible to program the process (for example, process of FIG. 3, FIG. 4) for implement | achieving the collapsed house information notification system by this invention according to OS which a computer can control. In recent years, many communication devices have a CPU and a required memory device, and many of them perform digital processing. Therefore, it is possible to implement the present invention using an existing communication device by installing the above program in a memory. Become. If such a program is recorded on a recording medium, the program can be operated anywhere by carrying the recording medium. As a recording medium for storing the program, a semiconductor medium (for example, ROM, nonvolatile memory card, etc.), an optical medium (for example, DVD, MO, MD, CD, etc.), a magnetic medium (for example, magnetic tape, flexible disk, etc.) ), And the program can be transmitted via the Internet or other communication means.
