Abstract
The present utility model discloses a heavy bob pendulum earthquake automatic monitoring system. The system comprises a heavy bob support, a hang spring fastened on the heavy bob support and a heavy bob suspended by the hang spring; a jam-proof device is arranged on the periphery of the hang spring, the heavy bob is arranged inside a constant temperature shading device, a photoelectric sensor and an electric bridge circuit are arranged inside the constant temperature shading device, the photoelectric sensor is connected with the electric bridge circuit, the electric bridge circuit is connected with an amplifier, the amplifier is connected with a data acquisition card; and a light source is arranged inside the constant temperature shading device. The system is simple in structure and low in costs. By adopting the system, large earthquakes can be predicted, destructive earthquakes measuring 7 or more than 7 Richter Scale are studied especially, and social benefits are greatly larger than economic benefits.
Description
Technical field
The utility model relates to a kind of earthquake monitoring system, is specifically related to a kind of weight pendulum-type earthquake automatic monitoring system.
Background technology
China is one of the most serious country that suffers disaster from an earthquake in the world.Along with the quickening of Chinese Industrialization and social modernization's process, Urbanization Process In China will further accelerate, and social economy also will develop rapidly.How the problem of earthquake disaster mitigation is just becoming increasingly serious.Although earthquake prediction is a universally acknowledged international science difficult problem, when strengthening various earthquake disaster mitigation measures, still must carry forward vigorously earthquake prediction study.Betiding 14: 28 on the 12nd May of 2008 Beijing time intensity is 8.0 grades Wenchuan earthquake, wrecked 69227 people altogether, and injured 374643 people, missing 17923 people's harrowing experience is also come clearly into view.Therefore, should with earthquake especially more than 6 grades the prevention work of moderately strong earthquake and 7 grades, 8 grades violent earthquakes bring up to critical positions.
Through retrieval, the patent No. is that the utility model of ZL201120006477.2 has proposed a kind of micro-earthquake monitoring system, comprise that 3-component earthquake sensor and/or acceleration detector, central authorities process computer and seismic recorder, although the micro-earthquake monitoring system of this utility model is simple in structure, but only the microearthquake activity of various mines (well) is monitored, and what the mankind were caused disaster all is some violent earthquakes more than 6 grades, thereby this patent application surface is relatively limited.The patent No. is that the utility model of ZL201120502468 discloses a kind of geological disaster monitoring system, it comprises administrative center, at least one Geological Hazards Monitoring district client and is arranged on the monitoring equipment in each Geological Hazards Monitoring district, although the data type of this utility model monitoring is comprehensive, but need a plurality of monitoring equipments, thereby cost is higher.
The utility model content
The utility model is for the deficiency in the background technology, a kind of weight pendulum-type earthquake automatic monitoring system is provided, its objective is utilize computing machine to the moderately strong earthquake data gather, preservation and playback etc., be applicable to seismic signal is carried out long-term automatically monitoring, because cost is low, also is applicable to middle school student's science popularization observation activity.
Technical solution of the present utility model: a kind of weight pendulum-type earthquake automatic monitoring system is characterized in that: described system comprises weight support, tie up to the weight that hang spring on the weight support and hang spring hang; Described hang spring periphery installs interference preventer additional, described weight places the constant temperature shade, and photoelectric sensor and bridge diagram are installed in the constant temperature shade, and described photoelectric sensor is connected with bridge diagram, bridge diagram is connected with amplifier, and amplifier is connected with data collecting card; Be equipped with light source in the described constant temperature shade.
The wood pagoda that described weight support adopts the less America pine of linear expansion coefficient to make.
Described interference preventer is sealed glass tube.
Described hang spring length is 5.2 meters.
Described constant temperature shade is the annual variation temperature difference less than or equal to 10 ℃ water-retention well.
Dark 5 meters of described water-retention well.
Described data collecting card is Altay PCI2300 data collecting card.
The beneficial effects of the utility model:
The utility model is simple in structure, and cost is lower.By enforcement of the present utility model, can predict violent earthquake, about 7 grades of primary studies and destructive violent earthquake more than 7 grades, its social benefit is far longer than economic benefit.
Description of drawings
Fig. 1 is the utility model system construction drawing.
Fig. 2 is the utility model system principle diagram.
Embodiment
Specifically describe the utility model below in conjunction with accompanying drawing and example.
As shown in Figure 1, weight pendulum-type earthquake automatic monitoring system comprises weight support 1, ties up to the weight 3 that 5.2 meters hang springs 2 on the weight support and hang spring 2 hang; Described hang spring 2 peripheries install sealed glass tube additional, and weight 3 places the annual variation temperature difference less than or equal to five meters of 10 ℃ dark water-retention wells 4, and photoelectric sensor 6 and bridge diagram 7 are installed in the water-retention well 4, also is provided with light source 5 in the water-retention well 4; Described photoelectric sensor 6 is connected with bridge diagram 7, and bridge diagram 7 is connected with amplifier 8, and amplifier 8 is connected with data collecting card 9-1 on the computing machine 9, and computing machine is connected with display 10; Described amplifier 8 is by the 24V DC power supply.
The specific works process:
As shown in Figure 2, Altay PCI2300 data collecting card is inserted the PCI slot of main frame, after installing driver, input pin with simulating signal access data capture card, amplifying signal is sent into data collecting card carry out A/D and be converted to digital signal and store in the register of data collecting card, products for further is processed.Use the Integrated Development Environment MFC coding in the Visual C++6.0 of the Microsoft design language, control PCI2300 data collecting card duty is stored, is processed data, realizes Real Time Monitoring.
Direction every year of weight indication, weight drew an anti-clockwise ellipse about about 15 degree in northwest (NW) west at surface level every year along with earth rotation, revolution motion have the variation of periodic regularity.The light that light source sends impinges upon on the hang spring, and shade drops on the photoelectric cell, if drop on two photronic centres, at this moment electric bridge is output as zero, if the shade of hang spring moves, and the electric bridge out of trim, at this moment electric bridge has 1～5 millivolt output, the ultra-weak electronic signal that relative motion between weight and the framework produces amplifies 100 times through amplifier, then inputs the input end of data collecting card, send into data bus through the A/D conversion, programming is kept at the two paths of data that gathers in the disk file.If near have the earthquake weight greater than 4 grades that obvious swing is arranged, ovalizing deflection, knotting and speed change.
