Embodiment Construction

[0027] like Figure 4 As shown, the embodiment in which the encoder (20) is installed in the kimchi refrigerator is described below, and it is set so that detailed options (kinds of kimchi, kimchi temperature, etc.) can be selected by rotation of the encoder (20). Thus, when the encoder (20) starts to rotate, a signal corresponding to the rotation of the encoder (20) will be transmitted to the microcontroller (10), which recognizes the Select the detailed option to judge the operating conditions of the kimchi refrigerator. In addition, the microcontroller (10) controls the operation of the kimchi refrigerator according to the judged conditions (kinds of kimchi, temperature, etc.).

[0028] Therefore, in order to select the detailed option corresponding to the operation of the kimchi refrigerator, when the user rotates the above-mentioned encoder (20) (200th step), it is judged that the signal transmitted to the microcontroller (10) through the rotation of the encoder (20) (s...

Abstract

An input method for encoder signals includes the following steps: judging signal periods: the signal generated during the work of the encoder judges the signal input period input by the micro-controller, a first control step: when the encoder signal is input into the micro-controller in a definite period, related items are selected based on the input signals, a signal counting step: when the signal is input into the micro-controller over the definite period, the input times of the encoder signals during the signal input period are counted and a second control step: when the counted input times in the counting step reaches to the definite times, related items are selected.

Description

technical field [0001] The invention relates to an input method of an encoder signal. Background technique [0002] like figure 1 As shown, at first the connection relationship of the loop is explained, an encoder (20) with two contacts (A, B) is set in the loop, and each contact A, B of the encoder (20) is connected to the microcontroller (10). In addition, a first resistor is connected between the contact A of the encoder (20) and the microcontroller (10); a second resistor is connected between the contact B of the encoder (20) and the microcontroller (10). . [0003] The user operates the encoder (20) to select a setting option, whereby the contacts of the encoder (20) are connected and a corresponding signal is input to the microcontroller (10). Thus, the microcontroller (10) will judge the option selected by the user and control the corresponding option. [0004] like figure 2 , image 3 As shown, in the embodiment of the prior art, the display part of the kimchi...
