Detailed description of the invention
Photoelectric encoder detector, including modulate circuit, panel and display screen; Modulate circuit, panel are connected by circuit according to this with display screen; It is characterized in that described panel is the micro-control making sheet based on Arduino; Panel is provided with 54 digital I/O pins, 14 analog input channels and 2 analog output channels.
Photoelectric encoder detector of the present invention, the I/O mouth output electric current of described panel is 135mA, and can carry voltage is 3.5V, and the 5V pulse produced through modulate circuit can not directly process. Signal conditioning circuit is for detecting the conditioning of signal, mainly AC signal to be measured, after filtering, amplifications, gating, RMS-DC converter, the process such as amplitude limit, deliver to microcontroller and measure. Sine wave signal A, B of the two-way phase 90 �� of photoelectric encoder output, becomes two groups of square-wave signals of a, b through Schmidt trigger. A is divided into two groups: one tunnel through peaker, and the rising edge at square wave forms pulse signal d, then is exported by gate circuit, formed and rotate forward pulse, the inverted device in another road, form anti-phase square wave c, form pulse signal e then through peaker, gate circuit export rp pulse g. B prescription ripple is attached directly to the control end of two gate circuits, as the gating signal of two gate circuits. When photoelectric encoder rotates forward, advanced 90 �� of b group signal, the corresponding rising edge without phase inverter a prescription ripple of its square wave positive half-wave, positive half-wave makes again gate circuit gating, and d group pulse is formed by gate circuit and rotates forward pulse; And the negative half-wave of rising edge correspondence b prescription ripple of c prescription ripple, though now peaker output e pulse, gate circuit is closed, it is impossible to output rp pulse g. When encoder reverses, situation contrast. The pulse of final output is respectively fed to control testing circuit and carries out counting the ARM of described panel and be set to 32. The intelligent display module being integrated that described display screen adopts. Described intelligent display module includes LCD display, lcd controller, touch screen, man machine interface process system and communication interface. LCDs shows, by script edit, the pulse number that microcontroller collection is brought in real time, and judges. PS-LCD, as advanced intelligent human/computer interface product, can realize data interaction by communication interface easy and flexible ground with external control unit outside. At present, PS-LCD supports two kinds of communication protocol: CTP(CookyTalkingPro-tocol) agreement and User Defined (UserDefine) agreement. What this detector adopted is CTP agreement. Under CTP communication pattern, PS-LCD, after receiving communications command, can perform at once, can return result to master controller after terminating. Owing to the serial communication protocol of PS-LCD is inconsistent with the communication protocol of microcontroller ArduinoDue, to carry out changing and controlling in communication process. Automatically reply message in order to what cancel PS-LCD command execution results, under CTP communication pattern, by calling ctpSet(" reply ", 0) function cancels automatically replying of PSLCD. The rs 232 serial interface signal that PS-LCD is produced by communication protocol simultaneously controls the work of microcontroller, really realizes the effect of human-computer interaction. Modulate circuit is used for this two paths of signals is carried out the signal processing such as shaping filter, finally delivers to Arduino panel. Arduino panel is used for realizing the counting of optical encoder pulse number, rotates forward, the differentiation of two kinds of pulse signals of reversion. Liquid crystal display circuit is used for showing the parameter of detection, carries out different model photoelectric encoder selecting control simultaneously.
