[0003]At present, the seismic monitoring equipment that China uses costs an arm and a leg by external import, and transmission mode is limited, can't realize monitoring for the inaccessiable place of electrical network.Native system measuring accuracy height, cost is low, utilizes solar power supply unit to solve outlying mountain area's monitoring point powerup issue, utilizes communication technology of satellite, carries out the transmission of data, is not subjected to any time and the influence in place, is convenient to extensive popularization and application.
China's area is vast, and existing monitoring equipment can't carry out unified monitoring to all zones, and resource can not realize sharing.In order to address these problems, we can be divided into several little squares according to certain distance with national domain, the building number of the short more monitoring of distance is many more, precision is just high more, each little square four point is all installed monitoring device of the present invention, the whole nation just has numerous monitoring point to cover like this, can cover the whole country.
Summary of the invention
The objective of the invention is existing monitoring equipment is replaced the use displacement transducer, simultaneously the power supply and the information transmission of equipment are improved, use solar powered and VSAT satellite communication to carry out transmission of Information, utilize GPS to carry out hi-Fix and accurately time service.A kind of rational in infrastructure, easy to use, with low cost, wide coverage, accurate positioning, communication advanced person's monitoring equipment and information transmission link are provided.
Patent of the present invention adopts following technology:
This system is made up of control center, monitoring center, satellite GPS hi-Fix technology, the accurate time dissemination system of satellite GPS and VSAT satellite communication subsystem.Displacement sensing system is realized the level to the monitoring point, the monitoring of vertical three-dimensional space, and the data of collecting are kept at data processing centre (DPC).GPS hi-Fix technology has been guaranteed the position of monitoring point.The GPS time dissemination system is to have guaranteed that acceptance and emission side have the synchronizing clock signals with the frequency homophase.Solar electric power supply system has high automatization level, can implement unmanned, can satisfy the daily powerup issue of equipment, efficiently solves the power supply that civil power can not reach the monitoring point.VSAT satellite communication subsystem is to utilize satellite link that data processing centre's test result is sent to control center, and control center can carry out real-time monitoring to a plurality of targets in the whole nation simultaneously.The entire system block diagram as shown in Figure 1.
Description of drawings
Fig. 1 is based on the earthquake real-time monitoring system theory diagram of satellite communication.
Fig. 2 VSAT satellite communication subsystem theory diagram.
Embodiment
At first solar power supply apparatus starts, and for equipment continues to provide power supply, control center utilizes satellite GPS location and time dissemination system the transceiver subsystem of national each monitoring point is all accurately located and to receive on the gps satellite clock source.Utilizing satellite link to send the signalisation total system starts working.When total system was started working, the displacement sensing of each monitoring point carried out level and vertical three-dimensional monitoring to the monitoring point.When vibrations took place, the sensor of monitoring point can produce displacement, reported to the police simultaneously, and passed information back control center by the sts satellite transmission system that is installed in the monitoring point.
Seismic event is with the outside expanding of arc mode, and near the generation displacement and the warning earlier at arc center, control center carries out prevention and withdraws preparation according to other monitoring center of position informing of vibrations point.
Each subsystem design is as follows in the patent of the present invention: 1, displacement sensing subsystem.
[0012]2, GPS location and time dissemination system
In order to make satellite and ground control centre, displacement monitoring point can accurately locate and have together the synchronizing clock signals of homophase frequently, adopt GPS location and time dissemination system among the present invention.This system is a high precision, low cost, round-the-clock and global radio navigation, location and multifunction system regularly.That the GPS technology has developed into is multi-field, the international new high-tech industry of multi-mode, multi-usage, multi-model.
Utilizing the GPS time dissemination system of gps system manufacturing, is time source with the gps satellite, has made up The present computer technology and gps satellite is accepted technology, can realize accurate time service, thereby realizes the precise synchronization of remote equipment.
The GPS time dissemination system frequency that apparatus of the present invention adopted can be 20MHz, 40MHz, 60MHz, 80MHz, and employed frequency is high more, and then precision is high more.
3, VSAT satellite system
VSAT satellite communication subsystem is made up of a main website (control center), satellite and 1 to k VSAT terminal (displacement monitoring point), three parts, and VSAT satellite communication subsystem theory diagram as shown in Figure 3.
[0020]Main website (monitoring center):
