The specific embodiment
Below in conjunction with Figure of description the utility model is done further to set forth.
As shown in Figure 1, the utility model comprises control device, sensor and host computer, and wherein control device carries out two-way the connection with host computer, and control device is connected sensor through control line with holding wire.
Said control device is single-chip microcomputer or PLC, and present embodiment adopts single-chip microcomputer.Sensor is a pulse counting equipment.
In the present embodiment, according to the actual conditions of punch devices such as rotary drill, every rotary drill is installed a cover depth tester, and wherein sensor is connected with the chain of rotary drill through gear, and supply voltage is DC10V-DC30V; Control device and host computer place in the driver's cabin of rotary drill, and the control device supply voltage is DC10V-DC14V; Adopt dedicated telephone line to be connected between sensor and the control device.Adopt RS232 private mask connection to be connected between control device and the host computer (present embodiment employing panel computer), upload the umber of pulse of punching so that calculate the degree of depth of punching in real time to Industrial Personal Computer (IPC) in real time.During installation, same cable adopted in the power supply of sensor and communication.
The operating principle of the utility model is: send instructions to control device by host computer; Send to sensor through control device then; Calculate the number of pulse again by sensor (pulse counter), then the pulse number that calculates is sent to Industrial Personal Computer (IPC), calculate the degree of depth of punching automatically.
In the utility model with the 80XXX Series chip as main control chip, RS232 conduct and PC link block, the LM7805 chip is as the Voltage stabilizing module of system.
The internal interface of main control chip 80XXX series is as shown in Figure 2; (1) the ingredient central processing unit (CPU) of this family chip is the core of whole single-chip microcomputer; This series monolithic is the processor of 8 bit data width, and it can handle 8 bit binary data or code.CPU mainly is made up of arithmetic logic unit, controller and special register three partial circuits.(2) program storage is used to deposit user program, initial data or form etc.(3) data storage can be deposited the data of read-write, the intermediate object program that disperses like the clouds or user-defined font table etc.(4) timer/counter, timer/technological device is used for the timing or the technology of hardware.80XXX has programmable Timer/counter of two 16, and (5) parallel input/output port is mainly used in external equipment and carries out communication, so that handle outside input and operation result is fed back to external equipment.(6) the full duplex serial port data of walking that are mainly used in other equipment rooms transmit.(7) interrupt system, change main control chip mainly by two outer interrupt, two timers, counters interrupt and one walk interruption.(8) clock circuit of the big 12MHZ of the built-in highest frequency of clock circuit can external concussion crystal oscillator and electric capacity, just can produce the pulse sequence of whole single-chip microcomputer operation.
In the present embodiment, sensor adopts incremental encoder (rotary-type).
During the rotation of incremental encoder axle, respective phase output is arranged.The differentiation of its direction of rotation and the increase and decrease of number of pulses need to realize by the direction judgment circuit sum counter at rear portion.Its counting starting point can be set arbitrarily, and can realize infinitely adding up and measuring of many circles.Revolution can also be sent the Z signal of a pulse, mechanical zero as a reference.Fixing when pulse, and when need improving resolution ratio, the two paths of signals with 90 degree phase difference A, B capable of using carries out frequency multiplication to former umber of pulse.
Incremental encoder has the photoelectric code disk that there is axle at a center; Logical, the dark groove of annular is arranged on it, have photoemission and receiving device to read, obtain four groups of sine wave signals and be combined into A, B, C, D; Each sine wave differs 90 degree phase differences (is 360 degree with respect to a cycle); With C, D signals reverse, be superimposed upon A, B two goes up mutually, can strengthen stabilization signal; The pulse of a Z phase of revolution output is to represent the zero-bit reference bit in addition.
Because A, B two differ 90 degree, can be through A relatively at preceding still B preceding, the forward and reverse with the differentiation encoder through zero pulse, can obtain the zero-bit reference bit of encoder.

What logical or dark groove resolution ratio-encoder provide be called resolution ratio whenever to revolve three-sixth turn, also claims to resolve calibration or directly claim how many lines, generally at revolution calibration 5～10000 lines.
Encoder machinery external form-encoder is with rotating shaft type branch, axonia and axle sleeve type; With resemblance and mounting flange branch, synchronous flange is arranged, clamping flange, compact; The axle sleeve type has type, full casement, large-diameter type in midair again.
The encoder diameter of axle-encoder diameter of axle has 6 millimeters
*, 8 millimeters, 10 millimeters
*, 12 millimeters, the axle sleeve type have 8 millimeters, 10 millimeters, 12
*Millimeter, heavy caliber 20-50
*Millimeter, band
*Number be conventional specification.
The utility model adopts high-precision sensor to carry out step-by-step counting, and the INT0 position is external interrupt 0 request.Its interruption mode of setting out can be selected, and when putting TCON.0=0, low level is effective; Trailing edge is effective when putting TCON.0=1.After interrupting successfully, will set up the IE0 sign to the CPU application.INT1 is external interrupt 1 request.Its interruption mode of setting out can be selected, and low level is effective when putting TCON.2=0; When putting TCON.2=1, trailing edge is effective.After interrupting successfully, will set up the IE1 sign to the CPU application.
Chip begins to carry out step-by-step counting when getting into interruption; Wherein count pulse is from corresponding outside input pin P3.4 (T0); When the input signal of this pin took place by high level to low level negative saltus step, the value of counter increased by 1, and this Series chip does not require the dutycycle of external input signal; This point is flat to be kept a machine cycle at least but generally will make, mainly be in order to ensure given level before variation at least by once sampling.Singlechip CPU is sampled to outside pulse signal input at the device of each machine cycle.If the sampled value in first cycle is 1; And the sampled value in next cycle is 0; Promptly detect the negative saltus step of pin level, then at the device of next cycle, counter increases by 1. owing to need two machine cycles to confirm once to count altogether; Promptly need 24 oscillator cycles, therefore the highest frequency of the count pulse of outside input is 1/24 of a single-chip microcomputer oscillator frequency.
