Description

  The present invention relates to a room safety prediction system at the time of an earthquake that visually shows a dangerous area and a danger level such as a fall or jump out by furniture of a room when a building shakes at a predetermined earthquake level.

  In recent years, methods and systems have been developed for predicting the degree of danger by simulating the vibration of a furniture or household appliance placed in a house during an earthquake during the earthquake.

  For example, Patent Document 1 is a technique for calculating the degree of risk due to shaking of a building at the time of an earthquake, and performs design of a floor plan of a building desired by a user, examination of arrangement of furniture, and presentation of an evacuation route.

  That is, as described in paragraph 0103 of Patent Document 1, the user can use the floor plan information, furniture layout information, resident information, earthquake information, etc. Simulation of earthquake occurrence. And, it is a support system that provides safe and favorite furniture layouts that ensure earthquake countermeasures.

  Patent Document 2 is a technique related to a risk determination method during an earthquake that is easy to understand visually and intuitively.

  That is, Patent Document 2 determines whether or not an object slides during an earthquake based on the position of a determination point on a determination chart for determining occurrence of slippage of the object (for example, furniture).

JP 2005-215998 A Japanese Patent Laid-Open No. 2005-84726

  Patent Document 1 is an earthquake simulation in which the dimensions of furniture are laid out in a room drawing and the risk level due to the shaking of the earthquake is calculated based on the layout drawing. And inform the results.

  However, shaking and collapse differ depending on the earthquake level. However, since Patent Document 1 does not describe a configuration requirement for performing a simulation according to an earthquake level (seismic intensity), in order to perform a simulation according to an earthquake level, the same items must be entered again for calculation. It takes time and man-hours.

  For this reason, since it takes time to inform the user that there is a dangerous place when the earthquake level is different, the user must wait until the result is obtained.

  In addition, the simulation is not performed according to the earthquake level, so it is not accurate.

  Furthermore, since Patent Document 1 merely informs the danger area due to an earthquake on the layout diagram of the room, it is difficult for the user to intuitively understand the degree of danger such as shaking or collapse of furniture.

  For this reason, there were many cases where it did not lead to an order for additional construction to prevent the collapse of furniture.

  Further, Patent Document 2 determines whether or not an object slips during an earthquake based on the position of a determination point in a determination chart for determining occurrence of slippage of the object (for example, furniture). Difficult to understand intuitively and intuitively.

  In addition, since Patent Document 2 does not perform a simulation according to the earthquake level for shaking, collapse, etc., in order to perform a simulation according to the earthquake level, it is necessary to put in the same items again and calculate. And man-hours.

  For this reason, since it takes time to inform the user that there is a dangerous place when the earthquake level is different, the user must wait until the result is obtained.

  The present invention has been made to solve the above problems, and directly displays the vibration experiment result according to the earthquake level, and more intuitively shows the furniture situation according to the vibration level of the earthquake to the user. The purpose is to obtain an indoor safety prediction system for earthquakes.

  The indoor safety prediction system at the time of earthquake according to the present invention is based on the vibration test result of shaking at a predetermined earthquake level with respect to the floor plan in the building in which the plane shape of the furniture is written. The indoor safety prediction system at the time of earthquake which displays the danger area by and the degree of the danger on the said floor plan in a building while displaying the state photograph of the said furniture.

A simulation unit that reads the input earthquake level and calculates the danger area and the degree of danger when the furniture of the floor plan in the building with the furniture is shaken at the earthquake level;
In the building during an earthquake, the color corresponding to the danger level is assigned to the corresponding area in the floor plan in the building with furniture, and this is displayed on the screen as the floor plan in the building by color in the dangerous area with furniture. A status display section;
It is provided with a photographic display section that reads a situation picture of the corresponding furniture when the furniture is shaken at the earthquake level and displays it on the floor plan of each color area of the dangerous area with furniture. And
