Multifunctional key communication method

Abstract

The invention discloses a multifunctional key communication method, and belongs to the technical field of communication methods. The method comprises the following steps of: enabling a single chip and a reception chip to be located in a sleep time period and waiting for awakening; after the sleep time is over, awakening the single chip and the reception chip external interruption, receiving a signal by the reception signal, sending the signal to the single chip, and detecting whether the received signal has a guidance code or not by the single chip; when the single chip detects that the received signal has the guidance code, detecting a pulse number of the guidance code; when the single chip detects that the pulse number of the guidance code in the received signal is greater than or equal to 3, judging whether the received signal has a synchronous code or not by the single chip; when the single chip judges that the signal has the synchronous code, receiving a data instruction code by the single chip, and judging whether a data bit pulse width length meets a requirement or not; and when the data bit pulse width length meets the requirement, judging whether the data is completely received or not by the single chip. The invention aims at providing the multifunctional key communication method which is convenient to use and good in effect; and the method is used for data communication.

Description

technical field [0001] The present invention relates to a communication method, more particularly, to a multifunctional key communication method. Background technique [0002] When the existing button signal receiving end is not in use, if the receiving end is always in a wake-up state and waiting to receive a signal, this method can receive a complete signal in time, but there are problems such as high power consumption and short standby time. The traditional button signal receiving end generally adopts the method of waking up the received signal at intervals, and uses ASK / OOK method to modulate and demodulate the data, that is, the amplitude shift keying method, which uses the presence or absence of the carrier signal to express the data "1" and "0". ", when there is a valid carrier signal, the receiving chip outputs a high level, representing data "1"; when there is no valid carrier signal or no carrier signal, the receiving chip outputs a low level, representing data "0"...

AI Technical Summary

Problems solved by technology

For example, when the button is pressed for the first time, the wake-up time is uncertain, and the second button is also random, so the traditional method cannot realize the function of turning on, off, and dimming; the wake-up efficiency and standby power consumption are also There is a contradiction. If you want to improve the wake-up efficiency, it is difficult to reduce the standby power consumption, or if you want to lower the standby power consumption, the wake-up efficiency cannot be improved.
