The recorder of present embodiment has 8 sampling channels: three-component vibration velocity sensor takies 6 passages, charge sensor and GPS time dissemination system and all takies 1 passage.Three-component vibration sensor and charge sensor can be installed from recorder 200 meters (, by transmission line to recorder, signal attenuation is in the scope of accreditation in 200 meters for the signal of sensor output).After three-component vibration rate signal is carried out branch gain amplification by the first preamplifier and the second preamplifier by the recorder of present embodiment, then signal is transferred to reach AD conversion unit synchronous acquisition.This recorder can continuous acquisition signal, every sampling channel sample frequency reaches as high as 10kHz, because sample frequency is higher, taking bigger memory space, need bigger transmission speed, therefore most of instruments all adopt some eigenvalue gathering signal, or adopt the pattern triggered, set certain threshold value, when signal is more than this threshold value gather, less than time just do not gather.It is therefore possible to miss some features of some useful signals or signal.So continuous acquisition signal of the present invention, collect the information of signal with better analysis.Additionally, recorder physical dimension is 237mm × 100mm × 158mm, weight is only 4043g, and volume is little, lightweight, it is simple to carries and installs, powering mode variation, also can adopt solar powered, be adaptable to various installation environment.
The recorder of present embodiment have employed high-frequency data collection and sync section index compression technology, it is achieved that retrieval, high accuracy data segmentation are quickly uploaded at a high speed, can high efficiency browsing data, statistics univers parameter, screening valid data when post processing.
Each log file group (the mine's shock signal data file of each recorder storage) is made up of two files: the data that a file storage is whole, referred to as data file；Another one is the real-time reduced index data to data file, referred to as index file.Two file parallel synchronous storage data in sampling process.All information in index file can again index from data file and obtain.Start record (including system reboot, user stops sampling and deposits reopening again) every time and all automatically set up corresponding new file directory, it does not have interrupting, subsequent file remains stored under this catalogue.
Two files all adopt block storage organization, and namely with data block for basic storage cell, data block is cumulative one by one forms data file.Data block basic structure is made up of two parts, build and data volume.Build describes the relevant information of data, data volume storage master data.
It addition, during for accurate pair, the microsecond clock of each collecting unit (each recorder totally 8 passage, every passage claims 1 collecting unit) independent synchronization record GPS time service data and control unit.This document takes simple row recording mode, increases a line record when each pair.Each catalogue next one GPS file, it includes data file, index file and three kinds of files of file when GPS pair.The data volume that the these three file unit interval produces is as follows respectively:
The data volume that the data file unit interval produces is: 10K (sampled point/second) × 8 (passage) × 2 (Byte) × 3600=576000Kbyte is about 576MByte/ hour；
The data volume that the index file unit interval produces is: 8 (passage) × 4 (Byte) × [1 (variance)+1 (average)+1 (maximum)+1 (minimum)+1 (head pointer)+1 (end pointer)] × 7200 (0.5 second record)=1382400Bytes is about 1.4MByte/ hour；
The data volume that when GPS pair, the file unit interval produces is: 60Byte (existing record entry length) × 144 (10 minutes intervals, number of times during every day pair) ... 365 (1 year)=3153600Byte is about 3.2MByte/；
Data file, index file, GPS time service file are saved in the hard disk of recorder.Index file is only uploaded when data are uploaded, the data that first index file received is called by data processing server are analyzed, adopt the ore deposit based on fractal theory to shake onset phase recognition methods and automatically identify mine's shock signal, if mine's shock signal, it is possible to directly invoke the data file that index file is corresponding.
