Vibration detecting transducer integrated with a network transfer function

Abstract

The present invention discloses an earthquake detection control system, comprising: a detection device, having a plurality of vibration sensors and a microprocessor, the detection device uses the ON / OFF states of the vibration sensors to detect the occurrence of earthquake and uses the microprocessor to calculate the number of the ON / OFF states so as to obtain vibration data; a central monitor computer 2 for receiving, analyzing and judging the vibration data and outputting an output signal representing earthquake intensity; and a control device 3 for generating a control signal according to the output signal so as to perform a predetermined control action.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The invention relates to an earthquake detection control system, and in particular to an intelligent earthquake detection control system, using an intelligent control method to complete the manufacture of an earthquake detector. First, a feedback control technique is used to sense the magnitude of vibration strength by a sensor, and then the sensed magnitude is transmitted to a central monitor center. After the central monitor center judge magnitude and hypocenter, a precaution action is taken and sent to local computers through a local area network. After that, before the seismic waves arrive, the local computers shut off immediately some important instruments (such as gas switches and main power switches) of dangerous installations which may cause a second disaster. When the earthquake occurs, an appropriate action is taken so as to attain the purpose of distributed control. [0003] 2. Description of the Related Ar...

Benefits of technology

[0009] The object of this invention is to design a vibration detecting transducer with network transfer and shut-off dangerous installation switch function (NT&SD Transducer) . It is not to predict the time of earthquake or to analyze the reasons of earthquake occurrence. According to this invention, a detection device as “NT&SD Transducer” is provided. While the earthquake occurs, the main control center will focus on the dangerous installations, such as natural gas plant and power plant, which may cause the secondary disaster, if they are shut down immediately before the seismic waves arrive, people will be protected from those equipments and the secondary disaster can be reduced.

Problems solved by technology

According to the detecting data of the past ninety years collected by the Central Weather Center, there is an average number of 2200 times of earthquake occurred in Taiwan each year, wherein most of them can't be felt by human, 214 times can be felt and almost one dangerous earthquake brings disaster.

Even the earthquake may not bring direct harm to the human and animals, the building may be destroyed as to hurt other people and animals after serious shaking, and thus the status of damage would be very serious.

While serious earthquake or after serious earthquake, at least one of the following damages may occur: The breakdown of the buildings, especially the public buildings, like theaters, schools, hospitals, markets and crowded area where many people get hurt or die; The collapse of the dam, the breakdown of the reservoir; and the route change of the river; The breakdown of the house, it turns that the gas, oil and oven may cause fire accident; The breakdown of the highway and bridge, the road may turns up or turns down, it may cause traffic jam that may delay the fire engine and the ambulance; it expands the crisis of the earthquake; and As to nuclear plant, it makes the radioactive material spread out.

Additionally, it also damages the electric power plant and causes fire.

In another aspect, it also damages the natural gas plants and makes the gas spread out.

As his paper, “Sensor for Gravitational Field and It's Application To Measure Against Large Earthquake Disasters” (Proceedings: Institute of Electrical and electronics Engineers 28th Annual International Carnahan Conference on, 12-14, 1994), where is a theory that applies the Gravitational Field to use the Michelson interferometer to measure earthquake magnitudes, however, it doesn't teach how people should adapt the immediate responding methods after earthquake occurrence.

This is a precisely seism scope limited to detection function, but it doesn't disclose the real time algorithm for processing methods.
