Detailed description of the invention
For further disclosing technical scheme of the present invention, elaborate by embodiment below in conjunction with Figure of description:
A kind of warning device for lubricant with over-standard water content, mainly formed by capacitor sensor, guard grating oscillating circuit, one-chip computer, 4 bit digital displays, phonetic alarm, the top, the end that it is characterized in that the plug in grease-box of capacitance sensor, one-chip computer and secondary instrument are arranged on night shift room distribution board; Monolithic calculation machine is selected the one-chip computer in AT89C52 series, includes the directly driving LED of RAM of 8KR0M256 byte; Capacitance sensor is selected HS1100 capacitance sensor to survey the square-wave signal of moisture signal after the conversion of the NE555 of guard grating oscillator and is passed to 16 system Counters of one-chip computer, timing ga(u)ge record arteries and veins signal deposits internal buffer in, proofread and correct through digital filtering piecewise linearity, calibrate moisture grade and finally pass to display demonstration and pass to phonetic alarm and report to the police;
The employing of element and principle performance
1, capacitance sensor adopts the HS1100 humicap that French HUMIREL company produces
Precision: ± 2% good linearity is exported;
Range: 1 ~ 99%;
Operating temperature :-40 ~ 100 DEG C;
Humidity output temperature influence is less, and normal temperature uses without compensation;
Response time: 5 seconds;
Interchangeability is good, does not need to proofread and correct;
Electric capacity and moisture variation 0.34pf(picofarad)/1%, water content is larger, and capacitance is larger;
Long-time stability and reliability: year drift value ± 0.5%;
Be applicable to Linear voltage output and two kinds of circuit of frequency output.
HS1100 is equivalent to a capacitor in circuit, its capacitance increases along with the increase of surveyed medium moisture, how to change accurately the variable quantity of electric capacity into computer and be easy to the signal of accepting? for reducing costs, simplify hardware circuit, I have adopted simple and reliable NE555 square-wave oscillator circuit, HS1100 is placed in to NE555 oscillating circuit, the variation of capacitance is converted to the voltage-frequency signal being inversely proportional to it, can be directly by computer acquisition.
2, NE555 oscillating circuit is as shown in Figure 2:
RA、RBWith measurement capacitor C, form the charge circuit to C, T end has formed again the discharge loop to C by the transistor shorted to earth of chip internal, and 2,6 ends are connected and are incorporated into comparator in sheet, just becomes a typical square-wave oscillator.
C1Be used for improving chip antijamming capability, suppression device temperature is floated. VD improves waveform symmetry, RB、WD
Form guard grating, the output of restriction energy.
3, two of oscillator temporary stable states are as follows: first power supply VCC passes through RA、RBTo C charging, after the t charging interval, UC(voltages at C two ends) reach the high triggering level of comparator in sheet, about 0.67VCC(supply voltage), now output pin 3 ends are low level by high level bust, then, pass through RBElectric discharge, through after t discharge time, UC(voltages at C two ends) drop to the about 0.33V of low triggering level of comparatorCC(supply voltage), now, output pin 3 ends are risen to as high level by low level. So go round and begin again, form square wave output, the time that wherein discharges and recharges is:
T charging=0.693RA*C
T electric discharge=0.693RB*C
RA=RBTime T charging=T electric discharge
Thereby the square wave frequency of output is F=0.722/RA* C. Visible Water in oil amount is just converted to by measuring oscillating circuit the frequency signal being inversely proportional to it.
4, host machine part selects AT89C5R series monolithic to include 8KR0M(read-only storage) the RAM(read-write memory of 256 bytes) direct driving LED (light emitting diode), and with high-performance, the low price one-chip computer of 8051 series monolithic software and hardware compatibilities.
5, the square-wave pulse signal of measurement electric capacity in importation after the conversion of NE555 oscillator sent into the T of single-chip microcomputer by NE555 oscillator tripod1，T1Working in mode 1, is 16 system Counters, time recording umber of pulse, and deposit core buffer (T0 works in the timer that mode 2 is automatic refitting mode) in. T1、T0An equivalent frequency meter of common composition. Frequency number is now exactly untreated moisture data, then after the correction of digital filtering piecewise linearity, calibration etc. are processed, delivers to and show and acoustic alarm unit.
6, display section
The signal of being sent here by main frame serial port enters serial parallel converter 74LS164 and P1Interface concurrent Signal cooperation
Drive 47 sections of LED charactrons to show data.
7, audible alarm part
Main frame, by P1 port output signal, drives loudspeaker by APR9600 voice module. Send the acoustic informations such as flooded condition, reason, processing method, how handling failure of prompting person on duty.
Owing to having adopted the HS1100 capacitor type water-containing sensor of function admirable, AT89C52 one-chip computer has obtained the linear approximate relationship of frequency signal and water content, carry out software filtering by computer, piecewise linearity is proofreaied and correct and the data processing such as computation of table lookup, error that can rectification building-out frequency is floated and components and parts cause. Particularly under maximum conditions after HS1100 water logging, sharply decline even failure of oscillation but still can correctly quote the audio alerts of a large amount of water inlets in fuel tank after processing by computer of oscillator signal.
