Embodiment

[0031] In the remote control signal receiving method in this example, since the lead code pulse width time of the air conditioner 0.1 degree accurate temperature control remote control signal is about 13 milliseconds, the timer timer0 timing time can be 15 milliseconds. The specific method is as follows:

[0032] Step 1. Preset a certain external interrupt INTx to trigger the external INTx interrupt on the falling edge or rising edge, and x is a natural number (that is, select an external interrupt INTx as the external interrupt that triggers the external interrupt);

[0033] Step 2. Wait for the external INTx interrupt caused by the input signal of the remote control to occur;

[0034] Step 3, if the external INTx interrupt occurs, the processor executes the interrupt service routine to determine whether the value of the first register step is 0, if not 0, then enter step 5, if it is 0, then enter step 4;

[0035] Step 4. Set the timer timer0 to 15 milliseconds, start the tim...

Abstract

The invention relates to a technology of remote control. The invention, solving the problem of low reliability of signal reception of existing air conditioner remote controller, provides a signal reception method of a remote controller, characterized in that: by applying a timer called timer 0 and determining the received pulse width time, the signal reception of the remote controller can effectively process and isolate interference signals. According to the invention, the reception efficiency and reliability of the remote controller signals are raised, and the method disclosed herein is suitable for the reception of the remote controller signals.

Description

technical field [0001] The present invention relates to remote control technology, in particular to the technology of air conditioner remote control signal reception. Background technique [0002] At present, the air conditioner generally receives the remote control signal and key signal by the indoor unit processor, and controls the indoor horizontal wind direction, vertical wind direction, indoor electric heating, indoor fan motor operation and indoor temperature sampling through decoding. The indoor unit processor also controls At the same time, the indoor unit processor handshakes and communicates with the outdoor unit processor through UART asynchronous communication, and transmits the remote control or key control commands and control parameters to the outdoor unit. The operating parameters are transmitted to the indoor unit, and the indoor unit further controls and displays the indoor unit and the outdoor unit through adjustment. The outdoor unit processor receives co...
