Specific introduction is done to the chip and operation principle that are related in the utility model below：
(1) OP07 amplifier chips
Required according to technical parameter, because the signal of electromagnetic field is fainter, the magnitude of voltage fluctuation range after original conversion
Less, the data after encapsulation do not have reference significance.Therefore, it is necessary to which magnitude of voltage is amplified.It is with design OP07 in system design
Amplifier chip is amplified step by step.OP07 chips are a kind of low noises, bipolarity (dual power supply) operation amplifier of non-chopper-zero-stabilized
Device integrated circuit.Because OP07 has low-down input offset voltage (being up to 25 μ V for OP07A), so OP07 is very
More application scenarios do not need extra zeroing measure.OP07 has input bias current low (OP07A is ± 2nA) and open loop simultaneously
The characteristics of high gain (being 300V/mV for OP07A), this low imbalance, the characteristic of high open-loop gain make it that OP07 is particularly suitable
In the measuring apparatus of high-gain and the small-signal etc. of amplification sensor.
(2) MAX306 chips
The collecting part of every equipment of requirement of system design can complete east, south, west, north, northeast, northwest, the southeast, west
South, the levels electromagnetic ripple signal of eight directional, the signal of local 5KM, 7KM, 10KM longitudinal electromagnetic wave signal, totally 11 road signals
Collection, the sampling of this part are responsible for sampling by original sensor.The signal being collected is converted to magnitude of voltage.Due to being that multichannel is adopted
Collection, and the data after gathering will carry out the input processing of data, data processing chip is STC12C5A08S2 single-chip microcomputers, the chip
ADC channel there was only 8 tunnels, therefore, it is necessary to inputted by MAX306 to carry out the selection of multi-channel A/D conversions.MAX306 is one 16
1 multiway analog switch is selected, therefore disclosure satisfy that the requirement of system.
(3) LM7805 chips and LM336 chips
1 LM7805 chip has been used in systems, and it functions as source of stable pressure use in systems, in acquisition system
The operating voltage of the processor chips of middle core is+5V voltages, so total electric power system in system will using LM7805 chips
It is used as voltage stabilizing, and supply voltage is stabilized into direct current+5V.On the other hand, A/D is changed and after the amplification of OP07 chips
Magnitude of voltage, between 0mv-500mv, in order to reduce magnitude of voltage distortion after amplification, therefore setting reference is contemplated that in the design
Voltage carries out the reference system after voltage amplification.System has used LM336 chips to carry out reference, anti-locking system to improve precision
The error of amplification is excessive.LM336 chips are an a reference source, there is two kinds of 2.5V and 5V, can be that voltage comparator etc. provides one
Individual very stable very accurate voltage reference value.Its feature is：Low-temperature coefficient, the wide μ A to 10mA of operating current 400,0.27 Ω are moved
The tolerance limit of state impedance ± 1%, it is specified that temperature stability, can easily finely tune to obtain minimum temperature drift.Core more than
Piece carries out the reference of voltage signal amplification, further improves the accuracy after gathered data.
(4) STC12C5A08S2 chips and RT5350 chips
Data processing module and data encapsulation uploading module：STC12C5A08S2 carries 8 road 10bit ADC, for gathering
The signal of sensor, sent by serial ports to RT5350.The processing of data, the one group of number of collection in every 20 seconds are carried out by RT5350 chips
In the flash carried according to deposit RT5350 chips.Data are carried out by crontab allocation lists by RT5350 chips within every 24 hours
Packing encapsulation.For packaged file with the entitled filename in time+ground, file format is bin forms.Again by being carried in RT5350 cores
The ftp agreements of the Openwrt system integrations on piece carry out long-distance Log server file to server end.
(5) display device
Single-chip microcomputer 4 connects LCD1602 LCDs and carries out real-time display, and the data gathered in real time are included
On LCD1602 LCDs, by observing the data on LCD1602 LCDs, check whether equipment is working properly.
It should be noted that the core of the equipment is in the RT5350 network chips of Lei Ling companies, loading Openwrt behaviour
Make system (a kind of operating system based on linux kernel exploitation), data are handled.It is simultaneously mono- using STC12C5A08S2
Piece machine is as adc data collector.Using 1602 liquid crystal displaying data in real-time, RT5350 is sent data to by serial ports.Will
The data of collection are calibrated by LM7805 chips and LM336 chips, and storage part and internet transmission of virtual laboratory are insulted based on thunder
RT5350 chip of the company based on MIPS kernels, 8M SPIFALSH, 32M SDRAM, 8GB USB flash disk etc. has been selected as storage
Device, and the peripheral circuits such as crystal oscillator, reset, power management and USB2.0 are extended, lOM/l00M Ethernet interfaces are extended,
RT5350 uses OpenWRT systems, and a kind of embedded system for aiming at router design based on Linux, its renewal speed is fast,
Software resource is more, and exploitation is convenient, portable high.RT5350 sends acquisition instructions in every 20 seconds by serial ports to single-chip microcomputer, then
Data are received from serial ports, and are stored data into local file, using place name+date on the same day as filename, after the completion of collection
Every 24 hours packaging files, data are uploaded to server by ftp programs.Software section, using based on linux kernel
Software platform of the OpenWrt operating systems as system, pass through shell programming realization network configurations.It is mainly pair in terms of program
Linux serial ports is programmed, and ADC collection is completed by operation of serial-port single-chip microcomputer, and data are reached by serial ports
Linux.Finally, by building ftp file server, the reception work of data is completed, user on the internet passes through service
Device IP address can downloading data.
It should be noted that the conversion of each subsystem line frequency/voltage advanced first, the voltage signal after conversion is through band logical
After filter circuit and amplifying circuit conditioning, the selection input channel of multi-channel A/D conversions is carried out by MAX306, is transmitted signals to
STC12C5A08S2 single-chip microcomputers are responsible for adc collections, using LCD1602 displaying data in real-time, are sent data to by serial ports
RT5350.RT5350 sends acquisition instructions in every 20 seconds by serial ports to single-chip microcomputer, then receives data from serial ports, and data are protected
It is stored in local file, filename was used as using place name+date on the same day.The time of the single-chip microcomputer collection plate of each subsystem, by
DS1307z chips provide time reference.Data are uploaded to server by ftp programs after the completion of collection.
Disclosed above is only specific embodiment of the utility model, and still, the utility model embodiment is not limited to
This, the changes that any person skilled in the art can think of should all fall into the scope of protection of the utility model.
