It is made up of video compression card, audio adaptation card, desktop bullet type camera, audio wire jumper, electric power supply extension cord, and video signal line. It is mainly applied in prison modernization management or other field.
Description
Technical field
The present invention relates to prison and obtain the Internet video field of Educational Technology.
Background technology
The Internet video technology realizes virtual face-to-face exchange by the network communications technology, making not can copolymerization at the dispersion user at a place, by multiple mode exchange of information such as figure, sound, reach people and carry out the application system that the real time information interchange is prosperous together, carry out collaborative work at a distance.Obtain management aspect at prison at present and do not adopt this Internet video technology, make in the level of putting in prison, work is made in education, political affairs and be subjected to certain restriction, as the women policeman who much has speciality and working experience owing to the restriction that is subjected to sex, can't enrich in supervision retrofit work one line, cause the surplus relatively of women policeman outside the prison, a spool is taught male policeman situation in short supply in the prison.In addition, the ideological problem, problem concerning life, the problem concerning study that are occurred in the process of serving a sentence of criminal is subjected to that condition restriction can not be resolved very soon in the prison.
Summary of the invention
For the subsolution women policeman that determines outside the prison superfluous relatively, the spool religion personnel situation in short supply prison in, some problems of criminal can be answered timely and accurately, help grasping criminal's personal considerations, improve the level of supervising retrofit work.The invention provides a kind of prison network remote video education system.
The technical solution adopted for the present invention to solve the technical problems is: be made up of video compression card 1, audio frequency adapter 2, desktop bullet type camera 3, audio frequency wire jumper 4, power extending line 5 and video signal cable 6.See Fig. 1 block diagram.Video compression card 1, the card face is yellow, one side has audio interface and video interface, opposite side has computer to connect (inserting) mouth, handle owing to adopt video compression card to make original compression calculating section transfer to compressing card, under low configuration computer, can better work, adopt video compression card and high definition pick-up head, the front-end collection definition is up to 480 lines, and can put after video compression to 800 * 600 resolution does not have sawtooth.Video compression card is that does not give unnecessary details in detail the commercially available prod.Audio frequency adapter 2, the card face is green, one side has three interfaces,---round---the round sequence arrangement of pressing square, and the square interface is a power interface, middle round interface and audio frequency wire jumper one end join, round interface and microphone join down, and the opposite side of audio frequency adapter has external power interface and computer interface, introduce the audio frequency adapter, can obtain better tonequality under same MIC (microphone) platform, audio-frequency unit can directly adopt plate to carry integrated sound card.The adaptive khaki electricity of audio frequency theory structure schematic diagram is seen Fig. 2, positive termination+12V DC power supply, negative terminal and capacitor C of diode D1 (IN4007) among Fig. 2
