Electrical wiring is: the Line 1 of rotary encoder 12 for itself power positive end with electronic counter+the 24V terminal links to each other; To be itself power supply negative terminal link to each other with the COM terminal of electronic counter No. 2 lines of rotary encoder 12; No. 3 lines of rotary encoder 12 are that its signal output A mouth is continuous with the signal input INA terminal of electronic counter; No. 4 lines of rotary encoder 12 are that its signal output B mouth is continuous with the signal input INB terminal of electronic counter; No. 5 lines of rotary encoder 12 are that its signal output Z mouth is continuous with the signal input INZ terminal of electronic counter; The power supply of electronic counter is powered by AC220V, is connected respectively to ACl, AC2.
(2) device for measuring force
As shown in Figure 6, load sensor 10 fits over the top of pulley 18, when steel rope 16 from the below of pulley 18 through out-of-date, application force is in load sensor signal input part 20, load sensor 10 is produced and the proportional pressure of steel rope 16 tension force, link to each other with digital display by shielded signal wire again.Electrical wiring is: the Line 1 of sensor links to each other with the signal+terminal of digital display for its output signal+utmost point; No. 2 lines of sensor are that its output signal-utmost point links to each other with the signal-terminal of digital display; No. 3 lines of sensor link to each other with the bridge pressure+terminal of digital display for its bridge pressure+utmost point; No. 4 lines of sensor link to each other with the bridge pressure-terminal of digital display for its bridge pressure-utmost point; The power supply of digital display is powered by AC220V, is connected respectively to source of AC 8,9.As by DC supply, DC12V is by 6,7 inlet wires.
Principle of work:
(1) measuring motion: constitute by rotary encoder 12 and electronic counter two parts.
Resolution: what logical or dark groove coder provide be called resolution whenever to revolve three-sixth turn, also claims to resolve calibration or directly claim how many lines, and this coder is at revolution calibration 30～5000 lines.
The signal output form: plug-type, the signal receiver interface of coder should be corresponding with coder.
Signal connects: the impulse singla of coder is connected with electronic counter.As single-phase connection, be used for folk prescription to counting, folk prescription is to testing the speed.A.B two links, and is used for forward backward counter, judges forward and reverse and test the speed.A, B, Z three link, and are used to the position measurement with the reference bit correction.A, A-, B, B-, Z, Z-connect, and owing to have the connection of symmetrical negative signal, electric current is 0 for the electromagnetic field of cable, and decay is minimum, and disturbance rejection the best can be transmitted larger distance.
Electronic counter is exactly one in fact and adds 1 counting machine, and its control circuit is subjected to software control, switching.To outside signal-count, the falling edge of external pulse is with flip-flop number by pin INA and INB.The counting machine pin incoming level of during the S5P2 of each machine cycle, sampling.If a machine cycle sampled value is 1, next machine cycle sampled value is 0, and then counting machine adds 1.After this during the machine cycle S3P1, the new count value counting machine of packing into.Need two machine cycles so detect a saltus step, so the highest count frequency is 1/24 of an oscillation frequency by 1 to 0.For example, if select the 12MHz crystal oscillator for use, then the highest count frequency is 0.5MHz.Though the dutycycle to external input signal does not have specific (special) requirements, be sampled at least once before variation in order to ensure certain preset level, the high level of external counting pulse and low level holding time all need at one more than the machine cycle.
After CPU was provided with certain mode of operation with software to counting machine, counting machine will no longer take the operating time of CPU by the mode of operation independent operating of setting, unless the spill-over of counting machine meter goes out the current operation of just possible interrupts of CPU.CPU also can reset the counter works mode, to change the operation of timer.This shows that counting machine is the high and parts flexibly of working of efficient in the micro controller system.
Counting machine is a kind of programmable part, so before counting machine was started working, CPU must write counting machine with number order (being called control word).The process that control word is write counting machine is the counting machine initialization.In initialization procedure, be with mode of operation control word writing mode register, mode of operation word (or relevant bits) writes control register, composes the counting initial value.
Control register counting machine INA and INB have 2 control register: TMOD and TCON, and they are used for being provided with the mode of operation of individual count device respectively, select tally function, and control starts operation, and as the sign of running state etc.Wherein, there are 4 in the TCON register in addition and are used for interrupt system.
(2) device for measuring force: form by load sensor and digital display.
Load sensor: this sensor is a resistance-strain type, and it mainly is made up of elastic sensing element (test specimen), resistance strain gage and measurement change-over circuit, is to make according to the principle of strain effect.When testing with strain-gauge, strain-gauge is sticked on the test specimen surface, behind the test specimen stress deformation, the resistor wire on the strain-gauge is distortion thereupon also, thereby the strain-gauge resistance value is changed, and converts the variation of voltage or electric current to by the measurement change-over circuit.
In this resistance strain type sensor, use be dc bridge circuit, four brachium pontis of electric bridge all are strain-gauge, the output voltage of electric bridge is directly proportional with resistance relative changing value and strain value.Adopt constant current source as the bridge circuit power supply to reduce nonlinearity erron.In actual the use, the resistance of each arm of electric bridge can not strictly equate, so even when not stressed, it is zero surely that the output of bridge circuit also differs, and therefore zeroing circuit must be set.Regulate zero potentiometer, electric bridge is tended to balance, output voltage is transferred to zero-bit, i.e. bridge balance in advance.
In actual applications, except adaptability to changes caused the strain-gauge resistance variations, temperature traverse also can cause the strain-gauge resistance variations, and it will bring error to measurement, therefore was necessary bridge circuit is carried out temperature compensating.But adopt the adjacent two arm temperature influences of full-bridge mode of operation electric bridge, produce equal and opposite in direction, the identical resistance increment of symbol simultaneously and cancel each other, thereby reach the purpose of bridge circuit temperature self-compensation.
Digital display: the measurement signal of resistance strain type sensor is connected to the signal input part of digital display by signal wire (SW), by measuring the numeric display panel table that amplifying circuit and peripheral cell are formed.Sensor adopts the foil resistance strain-gauge, and its normality resistance is 350 Ω.The resistance-strain amount that metering circuit produces sensor converts voltage signal output to.To press signal to amplify through the light current after the conversion, as the aanalogvoltage input of A/D converter.1.22V is provided reference voltage, its simultaneously after dividing potential drop as the VREF (Voltage Reference) of A/D converter.The two ends VREF (Voltage Reference) can compensate in right amount to the sensor nonlinearity erron.
This digital display adapted resistance strain type sensor can carry out physical quantities such as power.This digital display can use supplied by AC/DC electricity, exchanges to use 220V50Hz, and direct current uses external 12V/100mA.
Linear precision: be not more than 0.1% ± 2 word of reading value.Indication range: 0000～± 10000, arithmetic point can be set arbitrarily.Driving voltage: 5V/100mA sample rate: 3 times/second.
