Abstract
The utility model discloses a novel infrared receiver circuit for an infrared remote-control intelligent electricity-saving standby system. The novel infrared receiver circuit for the infrared remote-control intelligent electricity-saving standby system comprises a standby signal processing module, an infrared receiving chip U1 and a filter, wherein the output of the infrared receiving chip U1 is connected with the filter, the output of the filter is connected with the standby signal processing module, and the filter is an RC filter. The novel infrared receiver circuit for the infrared remote-control intelligent electricity-saving standby system is composed of the infrared receiving chip U1, resistors and capacitors, the structure of the infrared receiver circuit is simple and the cost is low. Due to the fact that the current-limiting resistor R1 is connected between a power source and a power source input pin of the infrared receiving chip U1, interference of the power source is reduced. The capacitor C1, the capacitor C2 and the resistor R2 form the RC filter, so that the anti-interference performance of a received infrared signal is made to be enhanced.
Description
Technical field
The utility model relates to a kind of infrared receiving circuit, particularly a kind of new infrared remote-controlled intelligent economize on electricity standby system infrared receiving circuit.
Background technology
The infrared remote-control device of existing low power electronics product energy-saving standby function, all adopt system's master chip to receive the infrared remote control standby signal, when system's master chip analyzes the idle function requirement, send the idle function signal by system's master chip and remove to control corresponding power supply.In this type of device, the detection of infrared signal has vital role, but the existing infrared signal testing circuit that is applicable to this occasion is comparatively complicated, and cost is higher, and antijamming capability is relatively poor.
