Embodiment Construction

[0036] One, structure of the present invention

[0037] refer to figure 1 , figure 2 , a digital input module for adjusting the display value of an electronic instrument, comprising a photoelectric code disc 1, a photoelectric sensor assembly 2, a processor 3 and an interface circuit 4 sequentially connected;

[0038] The photoelectric code disc 1 generates an optical pulse signal; the photoelectric sensor assembly 2 converts the optical pulse signal generated by the photoelectric code disc 1 into an electrical pulse signal that meets the needs of the processor 3;

[0039] Processor 3 judges the rotation direction and speed of the photoelectric code disc per unit time according to the received electric pulse signal and phase, and generates output signals. There are three types of output signals:

[0040] The first is the addition and subtraction control signal, which generates different addition and subtraction control signals according to the rotation direction of the phot...

Abstract

The invention belongs to the field of digital input module design and relates to a digital input module for adjusting a show value of an electronic instrument. The digital input module comprises a photoelectric coder (1), a photoelectric sensor module (2), a processor (3) and an interface circuit (4) which are connected in sequence. The photoelectric coder (1) generates optical pulse signals, the photoelectric sensor module (2) is utilized to convert the optical pulse signals generated by the photoelectric coder (1), the processor (3) judges the rotation direction and the rotating speed of the photoelectric coder (1), and operation of addition or subtraction of an indicated value of a display matched with the photoelectric coder (1) is achieved according to the rotation direction of the photoelectric coder (1). A hardware interface of the digital input module is convenient to connect, and few external circuit processor resources are occupied.

Description

technical field [0001] The invention belongs to the field of digital input module design and relates to a digital input module for adjusting display values ​​of electronic instruments. Background technique [0002] At present, there are mainly the following methods for data adjustment of digital input modules of electronic instruments: [0003] One is to refer to the layout of the small keyboard of the computer. The digit conversion is adjusted by the left and right arrow keys, and the numbers are directly entered by the keyboard; [0004] The second is to use the input method of four direction keys. The left and right direction keys adjust the digit to be changed, and each time the up or down direction key is pressed, the current digit is added or subtracted by 1; there are many keys on the input panel, and input operations The problem of low efficiency. [0005] The third is to use the left and right keys plus a rotary encoder. Use the left and right keys to adjust the d...
