  Recently, an emergency earthquake warning system has been established by the Japan Meteorological Agency, and systems and equipment that can receive distribution via the Internet, etc., have been deployed, and in the event of a major earthquake, it has become operational and issued. ing. This is an attempt to deal with disasters by using the time from the occurrence of an earthquake at the epicenter to the arrival of the damaged area in advance. However, in a direct earthquake, the earthquake early warning may not be in time. Therefore, in preparation for a direct earthquake or an earthquake with a relatively long epicenter, P-wave seismic detectors that directly detect vertical movements that are deployed in important facilities, facilities, equipment, and machinery, etc. There is an S-wave seismic detector that senses horizontal motion. In this way, earthquake detection bulletin systems and other earthquake detectors are becoming widespread as earthquake countermeasures, but there are currently many researches on accurate earthquake countermeasures such as misinformation, misinformation, malfunctions, and even malfunctions. There is room for.

  In addition, as the above-mentioned public earthquake early warnings are operated, the radio and television are not limited to general use, and each business office installs a dedicated receiving device and uses it to locate each business office. It is also becoming practical to utilize the information before the earthquake arrives, such as predicting the earthquake motion of the earthquake and performing emergency broadcasts as necessary. However, even in this case, there have been problems such as misreporting, time delay, and inadequate countermeasures for direct earthquakes, which are the limits of emergency earthquake warnings.

  The present invention relates to a new earthquake detection measurement system and its facilities / equipment, and the detection and measurement data of earthquake detection measurement devices installed in advance at each office, etc., as network information, between neighboring offices In addition, by sharing information on the server, checking each other's neighbors, selecting and utilizing the information necessary for oneself, and further utilizing the information between the regions together, it will respond appropriately to earthquake damage The purpose is to obtain the seismic detection measurement system and its facilities / equipment.

It is an earthquake sensing measurement system characterized by comparing and calculating the calculated value of data and the calculated value of own data, and issuing a command of its own as necessary, and outputs an operation signal there, For example, when the office is a manufacturing factory, various controls such as stopping of the equipment are automatically performed. At this time, by communicating all parameters, parameters suitable for each other can be used. For example, in a device in which damage is caused by the maximum acceleration, the maximum acceleration calculated by itself is compared with the maximum acceleration calculated by a nearby earthquake sensing measurement device. In addition, the server that collects certain areas as described above should create a time-series map of seismic motion by gathering information on P waves and S waves gathered in one place, and use it as data for determining the necessary area for damage recovery.

Further, a plurality of seismic sensing units of the seismic sensing measuring device described above are separately arranged at various locations, and waveform basic data obtained there is sent to one arithmetic processing unit installed at one location, and the plurality of basics An earthquake sensing measurement system characterized in that data is computed, and the computation results between each other are shared and compared, thereby displaying, recording, outputting an alarm, and the like. The configuration of the seismic detection measuring equipment and equipment used in.

It becomes the seismic detection measurement system and its facilities / equipment.

The figure explaining the earthquake detection measurement system of this invention. The circuit block diagram of the Example of the earthquake detection measurement system of this invention.

  FIG. 1 is a diagram for explaining an earthquake detection and measurement system according to the present invention. For example, in the vicinity of a certain area (A), there are offices (1) such as factories, schools (2), and hospitals (3). An area. The distance between each part is about 500 to 2,000 m. Each of these is equipped with an earthquake detection and measurement device, and each of them detects an earthquake, and the measurement data is connected as a net to form a network (W). Furthermore, it is connected to the server (S) and managed collectively. They are connected as a net in the adjacent fixed area (A ′) to the area where the office building (4), the theater (5) is located, and the area where the department store (6) and others (7) are located outside the area. (W) is formed.

FIG. 2 is a circuit block diagram of a seismometer as an earthquake detection measuring device installed in, for example, the business office (1). As an earthquake detection unit (PIC), a regulator (11) as a stabilized power source, A triaxial acceleration sensor (12) and an A / D converter (13) are connected in sequence and connected to the CPU (C ₁ ), where 10 sample input processing, average value calculation processing, and arithmetic processing unit for the next step (T) is transmitted to the CPU (C ₂ ) of the arithmetic processing unit (T) to become observation data, which is an external signal (Y), that is, the same seismic detection measurement of other buildings, etc. Output to the device to form the network (W).

  Also, here, only one earthquake detection unit (PIC), which is a part of the above-mentioned earthquake detection measurement device, is arranged in each place separately, and the basic data of the waveform obtained there is installed in one place.
