Background technology
On Microseismic Monitoring Technique is the important means of ore deposit shake monitoring, current existing micro seismic monitoring instrument is not the distributed sensing based on uniform transmission network, thus monitoring surface and port number all can not meet the actual demand of mine disaster monitoring, under environment of internet of things, need distributed ore deposit to shake monitoring means.Current micro seismic monitoring device does not have controllability, when not shaking generation, device still operation, the data collected are mostly the gibberishes such as neighbourhood noise, A/D converter conversion after by network by these useless resource transmission to processor.The data volume of distributed sensing transmission is natively very large, if acquisition phase can reduce the collection of these gibberishes as much as possible again, just can reduce the burden of processor to a certain extent.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art part, a kind of ore deposit based on precise clock synchronization agreement is provided to shake monitoring device, ore deposit shake monitoring device is controlled by controller, realize only gathering when ore deposit shake occurs and transmitting data, do not have ore deposit to shake not image data when occurring, A/D converter does not work.
For achieving the above object, the technical solution of the utility model:
Based on an ore deposit shake monitoring device for precise clock synchronization agreement, involving vibrations sensor, A/D converter, time service device, synchronization module, FIFO memory, cpu central processing unit, Ethernet, server; The output of described vibration transducer is connected with the entrance of A/D converter, the output of time service device is connected with the entrance of synchronization module, the output of synchronization module is connected with the entrance of cpu central processing unit with A/D converter respectively, time synchronized is realized between synchronization module and time service device, and producing sampling pulse to A/D converter, A/D converter carries out data acquisition according to this pulse; Cpu central processing unit is connected with Ethernet, FIFO memory respectively, and Ethernet is connected with server; The output of described A/D converter is connected with FIFO memory, the data of A/D converter Collect conversion are stored in fifo module, fifo module produces look-at-me to CPU after reaching half-full state, CPU starts to receive data after receiving look-at-me, and fifo module is transferred to CPU data successively; Synchronization module is connected with CPU serial ports, look-at-me is produced to synchronization module when Time Controller occurs in ore deposit shake, now, synchronization module generation time stabs and is transferred to CPU, first data transmitted from fifo module that the corresponding CPU of this timestamp receives, CPU is reportedly defeated by server this timestamp with the first number; The timestamp that subsequent data is corresponding calculates according to sampling rate.
Described vibration transducer exports and be connected with the controller that a control ore deposit shakes monitoring device between synchronization module, when vibration signal is greater than setting threshold value, produce a pulse signal, as the look-at-me of synchronization module, synchronization module produces sampling pulse to A/D converter after receiving look-at-me, A/D converter work; When vibration signal is less than the threshold value of controller setting, synchronization module does not produce sampling pulse, and A/D converter does not work.
Beneficial effect: the utility model is in order to realize the shake monitoring of distributed ore deposit, a kind of ore deposit is provided to shake monitoring device, can not only as the node of distributed sensing, but also can control data collection, do not gather or gather gibberish less, reduce energy consumption, reduce resource occupying, reduce the burden of processor.When there being ore deposit to shake generation, the data that vibration transducer collects are passed to CPU by A/D converter and are transferred to server by Ethernet; Not image data when occurring is shaken when there is no ore deposit.Its structure is simple, easy to use, has practicality widely.
