Abstract
The invention relates to television remote control equipment based on audience state detection. The television remote control equipment is hung on a roof between the audience and a television and comprises an infrared remote control switch, an image collector, an image processor and an AT89C51 singlechip microcomputer, wherein the infrared remote control switch is used for controlling the television to be turned on and off; the image collector is used for collecting a facial image of the audience; the image processor is connected with the image collector for processing the facial image of the audience; the singlechip microcomputer and the infrared remote control switch are respectively connected with the image processor to control the infrared remote control switch based on an image processing result. Through the television remote control equipment provided by the invention, whether the television is automatically turned off or not is determined according to the fact that whether the audience is in a sleep state or not when the television is in an operating state, so that a quiet sleeping environment is given to the audience while the energy source is saved.
Description
Technical field
The present invention relates to electronic monitoring field, particularly relate to a kind of television remote control device detected based on audience status.
Background technology
In the process of they watch TV machine, if spectators, because too tired or TV programme is too dull, may enter sleep state quickly, and at this moment television set can not be closed automatically, the brightness operation that television set still keeps original larger volume and presets, thus, spectators' sleep is now unstable, is easily disturbed by the sound of television set and brightness, its sleep is caused to maintain, meanwhile, the broadcasting of television set is also invalid broadcasting, is a kind of waste to the energy.
In prior art, in order to solve spectators fall asleep but television set still normally run cause television set wastes power and spectators sleep by the technical problem continuing to bother, at inside television, timing shutdown function is set, when spectators expect oneself future can enter sleep state sometime afterwards time, television set can be arranged to timing shutdown state by spectators, the time of setting can be selected between several predetermined fixed value, like this, when television set is after running the Preset Time selected by spectators, television set can shut down voluntarily, to spectators' quiet sleep environment.
But, there is following drawback in this solution of timing shutdown: (1) television set is after arranging timing shutdown, no matter whether spectators really enter sleep state, all can shut down by force, although the spectators giving the unused time not sleeping like this bring the trouble of again starting shooting; (2) timing shutdown can only arrange several limited Preset Time, and its shutdown controlling functions real-time is too poor.
Therefore, need a kind of new television remote control device, can detect audience status in real time, determine whether automatic shutdown immediately based on audience status testing result and TV current switch states, its real-time is comparatively strong, and control logic is more reasonable.

In addition, FPGA (Field-Programmable Gate Array), i.e. field programmable gate array, he is the product further developed on the basis of the programming devices such as PAL, GAL, CPLD, occur as a kind of semi-custom circuit in application-specific integrated circuit (ASIC) (ASIC) field, he solves the deficiency of custom circuit, also overcomes the shortcoming that original programming device gate circuit number is limited.
As far back as 1980 mid-nineties 90s, FPGA takes root in PLD equipment.CPLD and FPGA includes the Programmadle logic unit of some relatively large amount.The density of CPLD gate is between several thousand to several ten thousand logical blocks, and FPGA normally arrives millions of several ten thousand.The main distinction of CPLD and FPGA is their system configuration.CPLD is a somewhat restrictive structure.This structure is arranged by the logical groups of one or more editable result sum and forms with the register of the locking of some relatively small amounts.Such result lacks editor's flexibility, but but have the time of delay and logical block that can estimate to the advantage of linkage unit height ratio.And FPGA has a lot of linkage units, although allow him edit more flexibly like this, structure is complicated many.The difference of CPLD and FPGA another one is that most FPGA contains high-level built-in module (such as adder and multiplier) and built-in memory body.Therefore relevant important difference be much new FPGA support completely or part system in reconfigure.Allow their design along with system upgrade or dynamically reconfigure and change.Some FPGA can allow a part for equipment update and other parts continue normal operation.
FPGA have employed logical cell array LCA (Logic Cell Array) such concept, and inside comprises configurable logic blocks CLB (Configurable Logic Block), input/output module IOB (Input Output Block) and interconnector (Interconnect) three parts.
Field programmable gate array (FPGA) is programming device, and as compared to conventional logic circuit and gate array (as PAL, GAL and CPLD device), FPGA has different structures.FPGA utilizes small-sized look-up table (16 × 1RAM) to realize combinational logic, each look-up table is connected to the input of a d type flip flop, trigger drives other logical circuits again or drives I/O, thus constitute the basic logic unit module that not only can realize combination logic function but also can realize sequential logic function, these intermodules utilize metal connecting line to be connected to each other or are connected to I/O module.
Adopt the television remote control device detected based on audience status of the present invention,, control logic irrational technical problem not high for existing TV control mode real-time, volume detection technique and television image detection technique is adopted to judge whether TV runs, whether spectators enter sleep state to adopt image detecting technique targetedly to determine, and utilize the automatic closing television of infrared ray control technology, whole control procedure real-time is high, control is reasonable in time, on the one hand, energy consumption can be reduced, on the other hand, can ensure that spectators enter glitch-free sleep environment as early as possible.
