Below in conjunction with the drawings and specific embodiments, goal of the invention of the present invention is described in further detail, embodiment can not repeat one by one at this, but therefore embodiments of the present invention are not defined in following examples.Unless stated otherwise, the present invention adopts material and job operation are the art conventional material and job operation.
Principle of work of the present invention as shown in Figure 1.This invention provides a kind of remote vibration measurement instrument that vialog configuration parameter can be long-rangely set and blasting vibration signal is gathered and blasting vibration signal is uploaded onto the server automatically, this remote vibration measurement instrument comprises collector 1 and interchanger 2, and collector 1 is connected with interchanger by network interface; And described interchanger 2 is connected with server 3 by wireless network.
A blast signal acquisition method based on above-mentioned Acquisition Circuit, comprises the steps:
1) first collector is arranged to numbering;
2) then, interchanger sends a signal to the collector of reference numeral, and parameter and the collection signal duration of collector collection signal is set;
3) then, this collector gathers blasting vibration signal, and after collection, collector sends to interchanger in the mode of file by network interface by the numbering of the blasting vibration signal of collection and collector;
4) last, interchanger is uploaded onto the server file by wireless network again.
Particularly, first, for unique numbering is set on each collector.By this numbering, can find corresponding collector 1.Collector 1 transfer files to interchanger 2 time, sends the numbering of collector 1 simultaneously.
Collector hardware principle as shown in Figure 2.Collector 1 is the arm processor based on Linux embedded system.Wherein, because ARM11 chip provides numerous I/O hardware resources, such as serial ports, USB interface, SPI serial communication interface, LCD interface etc., can be the collector practical hardware resource of providing convenience.Therefore, this collector 1 adopts S3C6410 ARM11 as the first control chip; The first control chip is provided with serial ports controller, USB controller, SPI Serial Peripheral Interface (SPI) and LCD display interface.Collector 1 also comprises storer, analog to digital converter, sensor and the first access chip.Analog to digital converter adopts ADS1274 chip, and the first access chip adopts DM9000 chip.The first control chip is connected with storer, ADS1274 chip, and storer is also connected with ADS1274 chip.This collector adopts sensor to gather blasting vibration simulating signal.This sensor connects ADS1274 chip by 3 mouthfuls of GPIO passages, and this collector adopts ADS1274 chip to be responsible for analog to digital conversion, converts the blasting vibration simulating signal of sensor collection to digital signal and transfers to the first control chip to process.Wherein, wherein a bite passage of 3 mouthfuls of GPIO passages is responsible for simulating SPI sequential, and a bite passage is responsible for reading SPI data, and another mouthful of passage is responsible for having judged the moment of conversion.The work clock of ADS1274 is provided by the pulse-length modulation output of the first control chip inside.The first control chip is also connected with DM9000 chip, thereby this collector adopts DM9000 chip to be connected with interchanger, obtains the transmitted signal of interchanger and utilizes this DM9000 chip to carry out network interface monitoring.
ADS1274 chip is responsible for analog to digital conversion, converts the simulating signal of sensor to digital signal and transfers to ARM to process.ADS1274 chip switching rate is high, and the speed that SPI reads after conversion must be higher than the switching rate of ADS1274 chip.Because the SPI interface driver of Linux embedded system on ARM cannot meet the needed transfer rate of ADS1274, therefore the present invention adopts GPIO to realize SPI agreement.In the present invention, use 3 mouthfuls of GPIO passages to be connected to ADS1274, wherein a bite is responsible for simulating SPI sequential, and a bite is responsible for reading SPI data, another mouthful of moment of being responsible for having judged conversion.Strict control gathers SPI clock, makes it reach square wave, avoids the reading cycling in driving.The work clock of ADS1274 is provided by the inner PWM output of S3C6410, and this output can be stablized the pulse rate reaching more than 20MHz.
Owing to completing this high speed acquisition action need, CPU is strictly seized, so first close kernel when entering collection, seize, close all interruptions, start to gather, finish all interruptions of rear reduction and kernel and seize.Fig. 3 is the sequential chart of ADS1274.Collector is monitored and transfer files is all realized by DM9000 chip.
Wherein, collector 1 is the ARM equipment based on Linux embedded system, realizes following functions: on network interface, monitor the signal of waiting for interchanger.After the signal that receives interchanger, according to the parameter of signal setting collection signal, for example, gather duration, sampling rate etc., then start sensor gathers.In the process that sensor gathers, the blasting vibration simulating signal that collector 1 use ADS1274 chip collects sensor is converted into digital signal, and by these digital signal writing in files, by network interface, is transferred to interchanger 2.
Collector 1 is converted into digital signal by controlling ADS1274 chip at high speed by the blasting vibration signal of sensor collection.Because the SPI interface driver of Linux embedded system on ARM cannot meet the needed transfer rate of ADS1274.Therefore, the present invention realizes SPI agreement by GPIO passage and transfers at a high speed the blasting vibration signal of sensor collection to digital signal to reach.
The DM9000 chip of collector 1 is monitored the network port.When interchanger 2 sends a signal to collector 1, collector 1 analytic signal, according to the content of signal, arranges the acquisition parameter of sensor.After collection completes, collector 1 sends to interchanger 2 by the file of storage digital signal and collector numbering by network interface.
