Problems solved by technology

[0003] However, when the channel interference signal intensity of the radio frequency signal transmitted by the radio frequency module is strong, it is easy to cause the main control unit to fail to receive the completion signal fed back by the radio frequency module within the preset time, that is, the radio frequency signal transmission fails. At this time, the main control unit needs to control The RF module re-transmits the RF signal until the feedback signal is received within the preset time, and the RF signal is successfully transmitted

Abstract

The invention provides a remote controller radio-frequency signal sending method and system. Before a radio-frequency module is controlled to send radio-frequency signals, the interference signal intensity value of a channel to be used is detected, and radio-frequency signals are sent through the channel with the interference signal intensity value not larger than a threshold value, accordingly, radio-frequency signal sending success rate is improved, radio-frequency signal sending frequency is lowered, the time of a main control unit and the radio-frequency module in a normal-working mode is shortened, remote controller power consumption is lowered, and then the service life of a battery is prolonged.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, and more specifically, relates to a radio frequency signal transmitting method and a radio frequency signal transmitting system of a remote controller. Background technique [0002] The remote controller is mainly composed of three parts: a key, a main control unit, and a radio frequency (Radio Frequency, radio frequency) module, and the key and the radio frequency module are respectively connected to the main control unit. The remote control does not consider environmental factors when it is working. When the main control unit detects that there is a key input, the main control unit is activated from the standby mode to the normal working mode, and the radio frequency module is controlled to directly transmit radio frequency signals. When the main control unit receives the feedback signal within the preset time, it indicates that the radio frequency signal is successfully ...
