Abstract

The invention discloses a control signal generating circuit in the technical field of signal processing. The control signal generating circuit comprises a signal acquisition circuit, a signal processing circuit and a logic output circuit, wherein the signal acquisition circuit is used for acquiring a pulse signal of first equipment, the signal processing circuit is used for delaying the rising edge of the pulse signal to obtain a first signal and advancing the falling edge of the pulse signal to obtain a second signal, and the logic output circuit is used for carrying out logic processing on the pulse signal, the first signal and the second signal to obtain a control signal, delayed relative to the rising edge of the pulse signal and advanced relative to the falling edge of the pulse signal, of second equipment. The control signal generating circuit can be applied to a variety of man-machine interactive equipment and has a wide range of applications; the circuit is simple to implement, less susceptible to interference of external environments and is accurate in result; and no expensive processor is used, other software is not needed, and the manufacturing cost and the cost of software are reduced greatly.

Description

technical field [0001] The invention relates to the technical field of signal processing, in particular to a control signal generation circuit. Background technique [0002] Electronic products widely exist in modern production and life, providing great convenience for people's work and life. [0003] With the development of science and technology, many electronic devices of human-computer interaction have appeared. Such electronic equipment is generally divided into two parts. Part of the equipment is worn on the user's body or needs to be held by the user, that is, sports equipment, such as LED lights, infrared lights, signal launchers, etc. This part of the equipment is used to mark the user's operation; the other part of the equipment is fixed At a suitable location, the user's operation or action is collected and processed through a device worn by the user or a device held by the user, that is, a fixed device. Signal acquisition is usually achieved through video capt...
