Abstract

The utility model relates to an image signal receiving processor, and particularly to a WIFI based electronic whiteboard signal receiver. The WIFI based electronic whiteboard signal receiver comprises an image sensor, an optical imaging unit, a processing circuit and a WIFI module, wherein the optical imaging unit is connected to the image sensor; the image sensor is connected to the processing circuit; the processing circuit is mutually connected to the WIFI module; and a computer with a WIFI wireless communication function is mutually connected to the WIFI module arranged in the electronic whiteboard signal receiver through an internally arranged WIFI unit in a wireless manner. The WIFI based electronic whiteboard signal receiver has the advantages that: as most computers are provided with the internally arranged WIFI units, the computers can be connected to the signal receiver without any hardware operation to realize interaction; and the WIFI based electronic whiteboard signal receiver improves mobility and portability of a system on the basis of guaranteeing the performances of a whole machine, and has low cost and high efficiency.

Description

A kind of electronic whiteboard signal receiver based on WIFI

Technical field

The utility model relates to a kind of picture signal and receives processor, especially a kind of electronic whiteboard signal receiver based on WIFI.

Background technology

At present, interactive electric whiteboard system has become a kind of educational equipment of main flow, is widely used in various education activities, business meetings, educational training.Comprise the equipment such as computing machine that the electronic whiteboard application software is installed, projector, signal receiver, electronic pen, communication interface based on the interactive electric whiteboard system of image processing techniques.Wherein communication interface has determined the connected mode between the equipment such as computing machine and signal receiver, projector, under prior art, mostly be wired connection between the items of equipment in interactive electric whiteboard system, mainly communicate with USB interface, its shortcoming is that system wiring is wasted time and energy, the Long-range Data Transmission cost is higher, mobility is poor, use is inconvenient.In order to overcome above defective, improve mobility and the convenience of system, there is at present portioned product to adopt bluetooth to carry out communication between equipment.Application number be 201020104540.1 patent document disclose a kind of " bluetooth infrared electric whiteboard system " this system by electronic whiteboard software is installed and have computer, the projector of blue teeth wireless receiving function, the equipment such as bluetooth infrared electronic whiteboard receiver with infrared reception and Bluetooth transmission function consist of, be connected by the VGA line between computer and projector, be wireless connections between bluetooth infrared electronic whiteboard receiver and computer.Although this technical scheme has improved the mobility of system to a certain extent, Bluetooth protocol is comparatively complicated, and communication delay is long, coverage is less, and most of computing machine is not furnished with the embedded with bluetooth module, and cost is high, efficient is low, is not easy to popularize.Also have portioned product to adopt the 2.4G wireless communication mode to realize communication, application number is that 20120137423.9 patent document discloses a kind of " comprehensive interactive type wireless tutoring system ", comprise panel computer, projector, projector wireless server, optical identification wireless teaching pen and electronic whiteboard, wherein the light catcher of electronic whiteboard is by 2.4G wireless communication mode and panel computer wireless connections.Although such technical scheme has also strengthened mobility and the portability of system, because needs are independent, a communication adapter is installed and could be realized, same inconvenient, and stability is relatively relatively poor.Therefore, developing a kind of function admirable, the interactive electric whiteboard system that with low cost, mobility is strong, is the present technical issues that need to address.

Summary of the invention

In order to overcome the existing shortcoming of above-mentioned prior art, the purpose of this utility model is to provide a kind of electronic whiteboard signal receiver based on WIFI, it can utilize the intrinsic WIFI function of most computers low-cost, realize communicating by letter between computing machine and electronic whiteboard signal receiver quickly and easily.

In order to address the above problem, the utility model by the following technical solutions:

A kind of electronic whiteboard signal receiver based on WIFI comprises imageing sensor, optical imagery unit, treatment circuit, WIFI module;

Described treatment circuit is connected with described WIFI module, and the data transmission after described treatment circuit is processed it by the WIFI module is to wireless network;

Described WIFI module is connected with built-in computer WIFI unit, and two-way transfer of data and order.

The beneficial effects of the utility model are:

All be furnished with built-in WIFI unit based on most of computing machine, so computing machine need not any hardware operation and can be connected to the electronic whiteboard signal receiver, realize interactive; Simultaneously, wide coverage high due to WIFI technology maturation, bandwidth, time-delay are short, so overall performance can be protected.The utility model is specially adapted to be similar to the mobile device of can not maybe should not connect up communication, the extrapolation communication adapters such as iPad.
