Embodiment Construction

[0012] A home theater indoor lighting PID control system according to the present invention, the standard level is 5V TTL. It includes a video and audio signal acquisition module 1, a central control module 2, a bus adapter module 3, a node execution module 4, and a lighting effect acquisition and feedback module 5; Analyze the signal, identify the strength of the analog signal to be generated, and process it through the PID algorithm, use a decoder and a combination of logic circuits to convert the strength of the audio signal and video signal into a logical pulse for synchronous transmission, and send it to the central control Module 2; lighting effect collection and feedback module 5 collects the lighting effects near the viewer, and feeds back the signal to the central control module 2 synchronously; the central control module 2 uses the PID control algorithm to compare, adjust and correct the received signals , and transmit the command to the node execution module 4 throu...

Abstract

The invention discloses an indoor lamp light PID control system for home theater which comprises video frequency and audio signal collection module, central control module, bus adapting module, node execution module, light effect collection and feedback module. The video frequency and audio signal collection module directly analyzes audio signal and video signal input by TV, then processes signalby PID algorithm, converts audio signal and video signal to synchronously transmitted logic pulse, transmits to central control module; light effect collection and feedback module collects light effect around looker, and synchronously feedbacks the signal to central control module; central control module processes received signal by PID control algorithm and transmits command to node execution module by bus adapting module; node execution module receives control command and controls lamp light. The inventive indoor lamp light PID control system synchronizes sound, video and lamp light to match picture and sound effects by optimum lamp light so as to achieve a on-the-scene sensation for looker.

Description

technical field [0001] The invention relates to an indoor lighting control system, in particular to a home theater indoor lighting control system. Background technique [0002] With the continuous improvement of people's living standards, when watching a home theater, not only the pursuit of audio-visual super experience, but also the feeling of being on the scene. Especially for large-size TVs, the current home theater interface only has an audio acquisition interface, which has relatively low requirements for indoor light perception control, and cannot achieve the super experience of sound, light, and electricity. [0003] PID refers to proportional calculus regulation, (P-proportional, I-integral, D-differential,) PID controller is composed of proportional unit, integral unit, and differential unit. It is simple in structure, good in stability and reliable in operation , Easy to adjust. Adopt the current popular calculus control system (PID) in the field of process and ...
