The Research Of Data Receiving Software Based On LabVIEW

The earthquake information acquisition is in the seismic study important link, the earthquake information acquisition system's degree of development is significant to the seismic study. The earthquake data acquisition involves the sensor technology, the signal processing technology, the signaling technology, the computer technology and so on, it may carry on operations gathering, processing, analyzing, memory to the message data and so on. Data acquisition's communication mode has many kind of mature technologies, is widely applied in the seismic surveillance instrument. Because uses the interface standard is different, each instrument needs to have custom-made specially the application program, is very difficultly compatible with other instruments, this will increase the software even hardware cost greatly in many kinds of instrument mix service condition.In present commonly used seismic apparatus connection, this article stressed introduced the serial interface and the USB universal serial bus's movement principle, and take this as example explanation data receive flow.Have many methods in LabVIEW to realize with instrument connection docking, the article involves in virtual instrument software architecture VISA, interchangeable virtual instrument drivers IVI and connected the third party software connects through the dynamic link storehouse, through these methods, the majority of instrument's correspondence can easier.LabVIEW takes the present popular industrial standard present in figures and diagrams programming tool, by its rich function resources, integrates the massive connection driver, the nimble programming process, the friendly man-machine contact surface is the superiority, obtains the very widespread application in the measuring technique and in the instrument engineering science domain, obtains the very widespread application in the measuring technique and in the instrument engineering science domain. Uses LabVIEW to be possible to build the data acquisition processing system platform fast, has saved the massive study disposition connection agreement time and the energy for the programmers, will thus pay attention to the spot to put to the measurement result.This article in the research seismic signal gathering system's foundation, the contrast present popular instrument connection, proposes an general solution, may when the certain extent solution different instrument and the computer connect not unified has the software compatible question as a result of the connection, thus reduces the earthquake to observe personnel's operation to bear and to reduce software's purchase cost.
