Abstract
The utility model relates to a microcontroller external trigger blasting vibration recorder, which comprises a sensor 1, an outer shell 2, a printed circuit board 3 and electronic elements arranged on the printed circuit board 3. The utility model has the advantages that the utility model is single-channel, one instrument only measures one item of data, and one instrument cooperates with one sensor, so that the utility model works without transmitting conducting wires. Furthermore, the utility model has the characteristics of small size, light weight, low cost and simple operation. The utility model is in use in many types of work.
Description
The utility model relates to the explosion field of measuring technique, specifically a kind of microcontroller external trigger blasting vibration registering instrument.
It is that measured object converts electric signal to by a sensor that the explosion in past measures, and this electric signal is given the registering instrument record by transfer wire.Registering instrument can be an oscillograph, can be magnetic tape station, can be computing machine.No matter be anyly all must be placed on place to them, to guarantee safety away from explosion.And measurand all is near the buildings the blast area, gets very diffusingly, must give registering instrument the electric signal that the sensor of these dispersions is sent out by very long transfer wire.Have no idea to lay in a lot of work posts of very long transfer wire.Therefore difficulty is a lot of in operation.Said registering instrument is all huger, heavy in addition, price is also somewhat expensive.Measuring object is joined a magnetic tape station or a computing machine and is held economically and can't stand that the manpower consumption is also quite big.Be the time-consuming costly work of requiring great effort very much.
The purpose of this utility model is that a kind of volume of design is little, in light weight, and price is low, and the microcontroller that powered battery, measurand are joined an instrument touches the blasting vibration registering instrument outward.
The utility model microcontroller external trigger blasting vibration registering instrument comprises the simulating signal amplifier section, data acquisition, storage area, simulation output, digital output, external trigger control section, shell, sensor.
The simulating signal amplifier section: the electric signal of measurand is sent into the simulating signal amplifier section.Data acquisition, storage area are sent in the output of this part.
The simulating signal amplifier section is made up of three-stage amplifier.The first order forms high input-impedance stage, is in order to mate polytype sensor, to adapt to more measurement requirement, is dual power supply therefore.The second level is that enlargement factor is regulated, to adapt to the measurement of strong or weak signal.The third level is a level conversion, directly links to each other with data acquisition, storage area.It is made up of two linear amplifiers.The 1st grade and the 2nd grade is a slice, and the third level is another sheet.Directly be coupled by resistance between level and the level.
Data acquisition, storage area: this part is by microcontroller, program storage, and data-carrier store, analog to digital converter is formed.
Analog to digital converter will be simulated the analog signal conversion that amplifier section sends here and be become digital signal, and this digital signal is deposited in the data-carrier store by the program in the microprocessor controls executive memory.Data-carrier store promptly has power-down protection with the reserve battery power supply of low-voltage.Only otherwise do new record, former data can long preservation.
The simulation output.This a part of output signal directly connects oscillograph, magnetic tape station etc.As seen analog waveform.The simulation output is made up of digital to analog converter, low-pass filter.
The numeral output: digital output links to each other with data acquisition, storage area, and this a part of output signal links to each other with the serial digital interface of standard, and the confession computing machine is for data processing and analyzes.
External trigger control section: give the external trigger control section with the produced simultaneously trigger pip of blast signal, data acquisition, storage area are given in its output, the moment of the beginning of gathering in order to control data, data acquisition order, storage then, through the regular hour, storer has been filled with, and outage automatically is to save electric energy.
The external trigger control section is made up of logic element.The external trigger control signal is given or social connections, and this circuit is exported to d type flip flop, and the output of d type flip flop is connected with microcontroller, by this registering instrument opening entry of programmed control.
The advantage of the utility model microcontroller external trigger outburst vibration recorder is:
Our the microcontroller external trigger registering instrument of invention is single pass.Apparatus measures one an item number certificate that is to say that an instrument is joined a sensor, so it does not need to lay transfer wire.Volume is little, in light weight, low price, and is simple to operate.In many work posts, use terrible good economic benefits and social benefit.
Below in conjunction with accompanying drawing embodiment is elaborated:
Fig. 1 is a microcontroller external trigger blasting vibration registering instrument outside drawing.
Fig. 2 is a circuit block diagram.
Fig. 3 is a cut-away view.
Fig. 4 is circuit theory diagrams.
Fig. 5 is a flow chart.
Fig. 6 is a program listing.
According to Fig. 1-shown in Figure 6, sensor links to each other with amplifier, amplifier and by analog to digital converter, and microcontroller, program storage, the data acquisition that data-carrier store is formed, memory unit links to each other.Level translator links to each other with data-carrier store, and by digital to analog converter, the mould that low-pass filter is formed links to each other with data-carrier store with output.Gate circuit, d type flip flop links to each other with microcontroller.
Data-carrier store is powered with the low pressure reserve battery.Analog input signal can and oscillograph, magnetic tape station links to each other, the display simulation waveform, the mathematics output signal can link to each other with the serial mathematics interface of standard, does for computing machine that mathematics is handled and analysis.Above electronic devices and components are contained on the printed circuit board (PCB), and printed circuit board (PCB) is cased.Then assembling finishes.
