One kind splicing wall image control equipmentTechnical field
The invention belongs to video wall control technology field, more particularly, to one kind splicing wall image control equipment.
Background technology
With multimedia video as the fast development of industry, splicing video wall are widely used in every field, shopping blockOn exterior wall, several meters even tens meters of splicing large screen is commonplace.These Large video walls generally require it is several evenTens screens are spliced, and the Cooperation controlling problem of multi-screen increasingly obtains the attention of user.Control main at presentMethod is to select a mosaic screen to transmit total port as information, all information are delivered to this screen by backstage, this screenCurtain carries out a point transmission again.This ensure that the unification of transmission signal, but the screen as total port is often easier to damageBad and crash, therefore the processing of information and transfer function must be disposed individually.
On the other hand, if information processing transmission unit needs the single energy, be likely to result in as specific installationThe waste of the energy, therefore also need to energy detecting management module.
The content of the invention
The invention will solve the problems, such as to be to provide a kind of splicing wall image control equipment, solve to deposit in the prior artMosaic screen signal control disunity, the problems such as maintenance cost is high, control unit energy waste.
In order to solve the above technical problems, the technical solution that the invention uses is：
A kind of splicing wall image control equipment, including shell, power supply, touch-screen, data acquisition module, data conversion are providedProcessing module, image processing module, image switching control module, data transmission module and human body sensing equipment, the touch-screenPositioned at embedded case nose, the power supply, data acquisition module, data conversion treatment module, image processing module, image switchingControl module and data transmission module are located at enclosure, and the human body sensing equipment is electrically connected with the touch-screen.
After the control instruction that data collecting module collected is sent on the touchscreen to operator, pass information to data and turnProcessing module is changed, data conversion treatment module converts analog signals into digital signal and carries out filter and amplification, then passes toImage processing module, image processing module convert digital signals into picture signal and pass to image switching control module, figureAs switching control module carries out dividing processing to picture signal, and data transmission module is passed to, data transmission module is by signalPass to splicing each screen of wall image.
The human body sensing equipment includes infrared inductor, preceding camera and screen camera, the preceding camera and redOuter inductor is located at the right and left of cover top portion respectively, and the screen camera is located at shell right part front end.
Further, the touch-screen is resistive touch screen, capacitive touch screen or piezoelectric type touch screen.
Further, the shell includes external-connected port, and the external-connected port includes USB port, VGA port and and RJ45Interface.
Further, the power supply is DC power supply, AC power, lithium ion charge power supply or sun-generated electric power.
The invention solves existing splicing equipment control time disunity and control device is bulky to moveThe problems such as dynamic and waste of energy, the invention is easy to operate, easy to remove, applied widely.

Embodiment
Elaborate below in conjunction with the accompanying drawings to the specific embodiment of the invention.
As depicted in figs. 1 and 2, the invention include shell, power supply, touch-screen, data acquisition module, at data conversionManage module, image processing module, image switching control module, data transmission module and human body sensing equipment, the touch-screen positionIn embedded case nose, the power supply, data acquisition module, data conversion treatment module, image processing module, image switching controlMolding block and data transmission module are located at enclosure, and the human body sensing equipment is electrically connected with the touch-screen.
After the control instruction that data collecting module collected is sent on the touchscreen to operator, pass information to data and turnProcessing module is changed, data conversion treatment module converts analog signals into digital signal and carries out filter and amplification, then passes toImage processing module, image processing module convert digital signals into picture signal and pass to image switching control module, figureAs switching control module carries out dividing processing to picture signal, and data transmission module is passed to, data transmission module is by signalPass to splicing each screen of wall image.The image partition method that described image switching control module uses includes point based on threshold valueSegmentation method, the dividing method based on region, the dividing method based on edge and dividing method based on particular theory etc..
The human body sensing equipment includes infrared inductor, preceding camera and screen camera, the preceding camera and redOuter inductor is located at the right and left of cover top portion respectively, and the screen camera is located at shell right part front end.Work as preceding cameraDetected with infrared inductor in certain distance when there is no operator, then transmit information to touch-screen, touch-screen luminance-reduction orComplete blank screen, so as to fulfill saving energy of screen.
Further, the touch-screen is resistive touch screen, capacitive touch screen or piezoelectric type touch screen.
Further, the shell includes external-connected port, and the external-connected port includes USB port, VGA port and and RJ45Interface, can quickly realize the input of external information, so as to expand the information source of combination displaying.
Further, the power supply is DC power supply, AC power, lithium ion charge power supply or sun-generated electric power.When thisInnovation and creation structure do it is sufficiently small when, the use of charge power supply and sun-generated electric power improves the portability of the invention.
The embodiment of the invention is described in detail above, but the content is only the preferable of the inventionEmbodiment, it is impossible to be construed as limiting the practical range of the invention.It is all made according to the invention application range it is equalDeng change and improvement etc., shall remain within the patent scope covered by the invention.
