Description

In the event of a collapse of a building where people take work or rest inside, the present invention senses the person present in the building and grasps the position of the buried person so that the buried person can be rescued quickly. It can be related to a rescue system for distress caused by collapse. More specifically, an infrared sensor or a human body detection unit of a human body detection sensor is installed at a position where the detection of the ceiling or people inside the building is smooth, and the presence or absence of a person inside the building is detected. If an inclination sensor and an acceleration sensor are installed on the beam of the inner wall, the inclination data and the acceleration data that change when an earthquake or an external impact occurs are set as an event trigger signal, and the event trigger signal is generated, Judge that the building has collapsed, analyze the signal measured by the human body sensing unit for a certain period of time before the event trigger signal is generated, determine the presence or absence of people before the building collapses, this If there is a person, the position of the place where the person is buried is warned by voice or Morse code through the alarm / alarm unit, and the rescuer who arrives at the scene is alerted by the alarm / alarm unit. Grasps the position La Celle quickly advance the rescue operation, to rescue system distress by collapse mortality accidents collapse can be significantly reduced.

The social environment is changing rapidly and the frequency of occurrence of various large-scale disasters and accidents such as earthquakes, fires, explosions, collapses, etc. is greatly increasing. It is a fact that the scale of property damage is increasing.

Recently, the Sichuan earthquake and Haiti earthquake in China have caused many lives and property damage, and the most recent earthquake in Japan was a strong 9.0 earthquake with the best preparation for earthquakes. In Japan, the scale of the damage was unimaginable. Most of the damages caused by the above-mentioned earthquakes are caused by the collapse of buildings. The damage from the Sichuan earthquake is about 70,000, the damage from the Haiti earthquake is 230,000, Human lives have been damaged to the extent of 20,000 people. In addition, if a building collapses due to an earthquake, external impact, etc., there will be a life loss that will result in the death of the building, but it will be buried in the collapsed accident site and killed without prompt rescue work. The rate of damage was high, and some rescuers survived after being rescued several tens of days after being buried in the site of the collapse accident.

In the event of a collapse of a building due to an external impact such as an earthquake or explosion, rescue workers are thrown into the accident site after the occurrence of the collapse accident. The main activities will be to search for isolated rescue subjects and save them in a safe area, and to suppress disasters such as fires. However, the rescue target buried in the site where the collapse accident occurred is not a matter of losing consciousness or sending a rescue signal voluntarily in the collapse situation, so the position of the rescue target is not grasped It will be difficult to restore or search the site buried in the area. In addition, the rescue team members cannot search for a specific area of the collapse accident site, and only search for all buried areas and search for buried rescuers, and prompt rescue operations cannot proceed. . Therefore, the victims who were buried after the completion of the on-site pick-up for several days after the accident occurred could be rescued, resulting in an increase in human lives.

As a result, in the existing normal method, the position of the rescuer is not accurately grasped, and the position of the rescuer is determined by estimation based on the testimony of the witness, the designer, or the situation at the time of the accident.・ Because rescue work will be carried out in the area concerned, there is a risk that the rescue target who needs urgent may lose his life, and due to the characteristics of the accident site, the rescue work is done manually to prevent a chain accident. If the survivor's position and health status, etc. waiting for rescue cannot be grasped in other areas other than the applicable area, there is a risk that many lives will be lost. There is a situation where the time and effort involved are wasted, and the subsequent rescue work has a confusing result, the rescue work is delayed, and there is a problem that only accepts the unavoidable loss of human life accompanying this To do Always difficult situation has occurred.

It is a detailed block diagram of the data analysis part of a rescue system.

As shown in FIG. 1 to FIG. 3, the present invention is based on a structure in which a human body sensing unit 100 is in a normal state when a building in which people take business or rest occurs due to an earthquake or an external impact. If the inclination sensor 210 and the acceleration sensor 220 detect a sudden change in the inclination and acceleration of the building, this is regarded as a collapse of the building and is detected by the human body detection unit 100. If it is determined that there is a person inside the building just before the collapse of the building, it is determined that the person who was inside was buried by the collapse, and the alarm / alarm unit 400 is used. The location of the collapsed buried area stored in advance is warned, and when a collapse accident occurs, the rescue team can quickly grasp the location of the buried person and rescue the buried person preferentially.

The specific configuration of the present invention will be described in detail. The human body sensing unit 100 which is installed on a ceiling inside a building and constantly monitors the presence or absence of a person inside the building by an infrared sensor or a human body sensing sensor, and the building When the building collapses due to an earthquake or external impact when installed on a beam or a column on the inner wall of the object, the inclination sensor 210 and the acceleration sensor 220 analyze the inclination and acceleration data that change suddenly, and the inclination and acceleration data are Inclination and acceleration measurement unit 200 to measure as an event trigger signal, and when sudden inclination and acceleration data change due to an earthquake or external impact on the building, it is determined that the building has collapsed by considering this as an event trigger signal. , Data sensed by the human body sensing unit 100 a certain time before the tilt and acceleration data change suddenly Analyzes are made to determine whether or not there is a person inside the collapsed building, and if a person is detected, the location data of the installation location stored in advance is transmitted by low frequency RF (Radio Frequency). A data analysis unit 300 and an alarm alarm unit that warns the position of a buried place set in advance by an alarm sound when it is determined that there is a person who has been confirmed by the data analyzed by the data analysis unit 300 400 and the human body sensing unit 100 and the inclination / acceleration measuring unit 200 are supplied with power through a normal power supply during normal times. When it is difficult to supply a normal power supply due to the collapse of the building, the power supply is temporarily supplied through a battery in an emergency. The power supply unit 500 is configured to supply power to the alarm / alarm unit 400 to sound an alarm.

The human body sensing unit 100 is an infrared sensor that is installed on the ceiling of a building or at a position where people can be sensed smoothly, and is supplied with power through a regular power supply to detect the presence of a person in the building. Alternatively, measurement is always performed by a human body sensor, and the measured data is transmitted to the data analysis unit 300.

The inclination and acceleration measuring unit 200 is installed on a beam on the inner wall of a building and measures an inclination change caused by an earthquake or an external impact, and measures an acceleration caused by the earthquake or an external impact. An acceleration sensor 220, a signal processing unit 230 that amplifies and filters data measured by the inclination sensor 210 and the acceleration sensor 220, and an A / A that converts the inclination and acceleration data amplified and filtered by the signal processing unit 230 into a digital signal. The data measured by the inclination / acceleration measurement unit is transmitted to the data analysis unit 300, and it is determined that the building has collapsed when it exceeds the preset inclination / acceleration data change amount. This is used as an event trigger signal.

Data measured by the human body sensing unit 100 and the tilt / acceleration measuring unit 200 is transmitted to a data analyzing unit 300. The data analyzing unit 300 receives the data measured by the tilt / acceleration measuring unit 200 and receives the measurement. An event trigger that generates an event trigger signal that the building has collapsed due to an earthquake or external impact when a sudden change in slope data and acceleration data occurs and exceeds a preset reference value When an event trigger signal that a building collapses due to an earthquake or an external impact is generated in the generation unit 310 and the event trigger generation unit 310, the data received from the human body detection unit 100 is data for a predetermined time. The human body sensing extraction unit 320 for extracting the human body detection and the collapse extracted by the human body sensing extraction unit 320 occur. Analyzing the data before a certain period of time, and determining whether or not there was a person before a certain period of time before the collapse occurs, and before the building collapses in the human body detection determination unit 330 When it is determined that there was a person, assuming that the person who existed by the collapse of the building was buried, the position transmission unit 340 that propagates the position of the building stored in advance by low frequency RF (Radio Frequency), and the human body When it is determined that the person has existed before the building collapsed by the sensing / discriminating unit 330, it is assumed that the person who existed due to the collapse of the building is buried, and the collapse position information of the building stored in advance by the alarm / alarm unit 400 is used. The alarm / alarm control unit 350 is configured to control so as to warn by voice or Morse code.

At this time, the position transmission unit 340 can grasp the position of the building by propagating with low frequency RF (Radio Frequency) and adjusting the radio to the corresponding frequency.

When the alarm / alarm unit 400 determines that there is a person inside when the building collapses by the control of the alarm / alarm control unit 350 of the data analysis unit 300, an audio signal or a Morse code is used to indicate the buried position of the building stored in advance. Alerts the location of people buried when the building collapses, and rescue workers quickly determine the location of the buried subject, thereby saving the buried subject and minimizing damage due to rescue time delays be able to.

The power supply unit 500 supplies power to the human body sensing unit 100 and the inclination / acceleration measurement unit 200 through a normal power supply in a normal state to constantly measure, and the building is collapsed by an earthquake or an external impact. If it is difficult to supply regular power, replace the battery with power, and supply power to the data analysis unit 300 and the alarm / alarm unit 400 in an emergency. To be informed.

In addition, the inclination and acceleration measuring unit 200, the data analyzing unit 300, the alarm / alarm unit 400, and the power supply unit 500 constitute a housing 600 so as to be able to withstand an external impact when the building collapses. It is installed inside the door to protect it from the impacts that occur while it collapses so that it can be driven smoothly. In addition, a digital clock or the like can be formed on the surface of the housing 600 to enhance practicality.

The present invention having the above-described configuration prevents human life damage that occurs when people who could not be saved due to the collapse of the building are buried in the collapsed building without being rescued early. Because most of the people who were buried after the collapse of the building were not killed at the time of burial, but lost consciousness and could not transmit independent rescue signals, the rescue crew members collapsed The only way to find and rescue the site was to find out who could not be saved inside the building if a burying accident occurred. Quick rescue operations.

Explaining the driving sequence of the present invention, when a collapse accident occurs due to an earthquake or an external impact in a building, the human body sensing unit 100 is normally installed on a ceiling or the like inside the building where it is easy to grasp the presence or absence of a person. Sometimes the presence or absence of a person is always grasped, and if an earthquake or external impact occurs in the building, the inclination and acceleration measuring unit 200 measures the inclination data and acceleration data of the building applied by the earthquake or external impact, The analysis unit 300 analyzes the measured inclination data and acceleration data, and if the change amount of the inclination and acceleration data changes exceeding a preset reference value, it is determined that the building has collapsed, and this is an event trigger. Use as a signal.

If a change amount exceeding a reference value is detected in the tilt data and acceleration data, an event trigger signal is generated, and the data constantly measured by the human body sensing unit 100 is used for a certain time (for example, 30 seconds before) when the collapse occurs. The previous data is extracted, and it is determined whether or not a person is sensed by the extracted data. If it is determined from the extracted data that a person is present, the collapsed position of the building stored in advance is propagated by low frequency RF (Radio Frequency), and the position information of the person buried at the time of the collapsed accident is transmitted to the radio. If a certain frequency is adjusted via the alarm, the alarm information on the location of the building that has been set in advance by the alarm / alarm unit 400 is alerted by voice or Morse code to rescue the site where the collapse accident occurred. By transmitting the position information to the member, the rescuer can search for the corresponding position and quickly rescue the buried subject, thereby minimizing the human life damage caused by the buried subject.

As described above, the preferred embodiments of the present invention have been described. However, the present invention is not limited to the above-described embodiments, and the present invention belongs without departing from the gist of the present invention claimed in the following claims. It can be said that anyone having ordinary knowledge in the field has the technical spirit of the present invention to the extent that various changes can be made.
