The present invention utilizes the preceding terrestrial magnetic field of earthquake that the principle of disturbance can take place, and it can monitor the abnormal disturbances of terrestrial magnetic field state and warning terrestrial magnetic field for a long time; The present invention adopts virtual instrument technique, has saved hardware cost greatly, and the demonstration of data, preservation, subsequent treatment are all carried out on computers the virtual instrument software; Terrestrial magnetic field state and abnormal data are preserved into format, be stored on the PC hard disk, form is simple, can monitor the endless time, shows in real time and draws terrestrial magnetic field data and time curve; When the abnormal disturbances of terrestrial magnetic field, can send various alarms and make record; The Monitoring Data form simply can read easily, copy; Monitoring Data is carried out subsequent treatment, statistics, analysis, and personnel provide basis for estimation for seismic study; Make things convenient for simultaneously Monitoring Data is carried out exchanging between subsequent treatment and the seismic study personnel.
Description of drawings
The invention will be further described below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present invention.
Fig. 2 is a software function block diagram of the present invention.
Embodiment
Referring to accompanying drawing, the present invention has computer and magnetic field sensor, and magnetic field sensor sends character string by the RS232 serial ports to the computer serial ports simultaneously by the USB confession electricity of computer.Read a string 16 system data that magnetic field sensor sends over by serial ports by the virtual instrument software on the computer, described virtual instrument software intercepting two effective bytes wherein, carrying out system converts, data processing such as orientation values calculating obtain the terrestrial magnetic field orientation values, with this orientation values and this ground normally the magnetic field orientation values relatively be converted into terrestrial magnetic field state (normal state, anomalous mode) is presented on the computer user interface, described virtual instrument software call function is read each pairing time of terrestrial magnetic field orientation values, real-time rendering goes out the X-Y scheme of terrestrial magnetic field orientation values and corresponding time, with the terrestrial magnetic field state, orientation values and time corresponding are preserved into data file, as Monitoring Data, for later research is given information, Monitoring Data is carried out subsequent treatment, calculate average, variance, ASSOCIATE STATISTICS parameters such as probability density, personnel provide data refer for seismic study; When abnormal disturbances took place in the terrestrial magnetic field, described computer will send abnormal alarm, and this moment terrestrial magnetic field orientation values and time keeping in the abnormal data file.
In the present invention, described virtual instrument software comprises acquisition module, display module, preservation module, alert module, data processing module.Wherein the each several part function is:
Acquisition module: the correlation parameter of serial communication is set, comprises baud rate, data bit, parity checking etc.The 16 system character strings that send over of read sensor also show, and intercepting effective byte (directions X terrestrial magnetic field orientation values and Y direction terrestrial magnetic field orientation values) is wherein carried out numerical value conversion, formula calculating etc. to this two byte data and obtained the terrestrial magnetic field orientation values.
Display module: the terrestrial magnetic field orientation values when the no earthquake in the terrestrial magnetic field orientation values that described virtual instrument software is calculated and this ground takes place relatively, difference is thought normally within setting range, surpasses setting range, thinks unusual.With current terrestrial magnetic field state (normal condition/abnormality), be presented on the computer user interface in real time; Described virtual instrument software is when calculating the terrestrial magnetic field orientation values, and call function reads the time value (date Hour Minute Second) on the computer in this moment, draws the two-dimensional curve figure of terrestrial magnetic field data and corresponding time.
