As shown in figure 12, in the present embodiment, the utility model comprises a printing list unit 24, links to each other with parallel printer, it has the interface and the sequential of standard, but its voltage is according to 5V design, but the I/O mouth of LPC2000 series is 3.3V, is the driving force that guarantees output, its data port has increased line driver 74HC245, and the control mouth also must carry out level conversion, and this realizes that by the CMOS gate circuit circuit of parallel printer interface is seen Figure 12.Because the I/O mouth of LPC2000 series can bear the 5V input,, can increase security but increase it so the resistance among the figure not necessarily.
As shown in figure 13, simulating signal is isolated: in a lot of systems, simulating signal must be isolated.Signal Isolation Technology is to make simulating signal not exist the electric current that passes through barrier between transmission and the receiving end to connect when sending.This allow to send and the receiving end ground or the difference of reference level outward can be up to several kilovolts, and has prevented to damage the differently loop current between the current potential of signal.The noise of signal ground can make signal impaired.Isolation can make Signal Separation to a clean signaling subsystem ground between sensor, instrument and meter or control system and the power supply and isolate mutually, thus the work safety of assurance total system device, reliable and stable.Realize transmission of industry spot Signal Spacing and conversion, ground wire disturbs and suppresses the long-range undistorted transmission of signal, the isolated variable of instrument and meter and sensor signal.As shown in figure 13, ISO 4-20mA series sensor current signal is converted to the voltage signal of 1-5V through R301, R302, RP1, the RP1 effect is that benchmark is regulated, V142G1 is a signal isolator, it is one is light signal with electrical signal conversion, the HNR200 linear optical coupling realizes that 3 pin can obtain the 1-5V voltage signal after the conversion.Another problem to Signal Spacing is the required power consumption of isolated amplifier input stage, and the input impedance of isolated amplifier and the equivalent resistance of self are the key points of problem.And output stage is a benchmark with casing or ground usually, and input stage is floated usually on another current potential.Therefore, the power supply of input stage also must be isolated.DC/DC is integrated into V142G1 forms a complete Signal Spacing module.
Principle of work: referring to shown in Figure 1, with a road in the two-way grouting operation is example, in filling process, at first the grout with certain proportioning injects tank diameter 13 stirrings, by grouting pump 14 slurries are pressed into wellhole 16 along pulp-inlet pipe 23 subsequently, the slurries that partly or entirely can't infiltrate the rock stratum in the wellhole 16 are under the effect of wellhole 16 internal pressures, flow out by return pipe 21, flow through tensimeter 19, pressure valve 17, return slurry flowmeter 22, densitometer 20 and return tank diameter 13 at last, after stirring, repeat this process, finish up to grouting.In this process, the slurries that flow through pulp-inlet pipe 23 are by advancing to starch flowmeter 15 meterings, flowing through the slurries that return slurry flowmeter 22 measures by returning slurry flowmeter 22, separately signal is delivered to the Signal Spacing passage of monitoring system of the present invention, input to CPU (central processing unit) through the AD ALT-CH alternate channel, calculate the two difference by monitoring system, be the actual slurry amount that pours in the wellhole 16.Return the pressure valve 17 of starching in the loop by adjusting, can change the pressure in the wellhole 16, the big more infiltration that is beneficial to slurries to the rock stratum more of pressure, but pressure should be suitable, pressure gauge 18 is delivered to the Signal Spacing passage of monitoring system of the present invention with force value, inputs to central control unit 1 through the AD ALT-CH alternate channel, and system writes down and analyzes, if actual pressure and design pressure deviation are bigger, the force value of demonstration will be warned with yellow.As shown in Figure 3, because monitor of the present utility model adopts embedded OS, therefore two threads in the middle of can be regarded two application programs in the operating system as, from user's angle, two application programs are concurrent, and are separate, can move simultaneously, from the angle of microcosmic, two programs are by the priority timesharing scheduling of operating system according to each thread, but finally can both finish task separately on time.
