Abstract

The invention relates to a method for reducing the stand-by power consumption of a wireless transceiver system, comprising the step of: setting the primary transmitting time of a coded signal of a transmitting device in the wireless transceiver system to be bigger than the sum of the sleep time of a micro processor of a receiving device and the power-on time of the micro processor after being waken up; setting the micro processor of the receiving device in the wireless transceiver system to enter the sleep state by utilizing a watchdog; the receiving device quits the sleep state after receiving the coded signal sent out by a primary transmitting device. The invention also relates to a wireless transceiver system. Implementing the method for reducing the stand-by power consumption of the wireless transceiver system and the system has the following advantages that the shortest possible intermittent power supply and longest possible sleep time in a fixed cycle can be achieved, and moreover, any possible foreign signal reception can not be missed.

Description

technical field

[0001] The present invention relates to the radio field, and more specifically relates to a method and system for reducing standby power consumption of a wireless transceiver system. Background technique

[0002] In battery-powered electronic products, users require as long a standby time as possible, that is, the battery requires as long as possible use time. Do not miss any signal that should be received, which puts high demands on the standby power consumption of the product. For the transmitting circuit, it is easier to solve this problem, because it only turns on the power and transmits once when the button is pressed, and completely disconnects the circuit from the battery without pressing the button. But the problem of the receiving circuit is much more difficult. The reason is that in order to achieve ultra-low power consumption in standby, the receiving circuit has to enter the sleep mode, but the microprocessor (MCU) of the product suspends the exe...
