The utility model discloses after utilizing the traditional video matrix host computer of TVI simulation high definition signal conversion chip butt joint, realize super multimode and plan the input and the switching of high definition, realize high way high definition HDMI output lug connection display screen simultaneously.
Description
Technical field
The utility model relates to security device.
Background technology
In safety-security area, the full name of TVI is HighDefinitionTransportVideoInterface, i.e. HD video coffret.Digital signal can be converted to simulation by TVI, and it can be extended transmission distance, and reduce total cost, and required memory capacity is less.Its distance through co-axial cables transport can reach 300 ~ 500 meters.In addition, TVI can transmit CVBS75 ohm analog signal, and 1,080P and the 720P that realize 30fps transmit.
In the past in Two decades years, the scheme of the main application simulation monitoring of whole world video monitoring video realizes monitoring, front end is common simulation video camera, by 75 Ω coaxial cables by transmission of video to control centre, after (traditional analog matrix is BNC analog input, BNC modulating output) being switched to video by traditional analog matrix, then access common splicing controller output to display splicing screen show again.Traditional simulation SD monitoring can only realize the low definition video monitoring of 420 lines, 480 line equal-specifications, picture is fuzzyyer, when running into security incident, be difficult to clearly in the record picture of existing supervisory control system see the facial feature of personage or the course of emergency of event, make relevant unit be difficult to obtain conclusive evidence in follow-up evidence obtaining process.
Summary of the invention
The utility model is in order to solve above-mentioned problems of the prior art, a kind of safety device inputting multichannel TVI signal is provided, comprise TVI signal input sources, display screen, the switching output module that TVI signal input sources is connected with display screen, described switching output module comprises at least one for accessing the analog signal tablet of multichannel TVI signal, at least one TVI multichannel TVI signal being converted to the output of HDMI signal turns HDMI module, the output signal of each analog signal tablet is switched to the mother matrix that TVI turns the input of HDMI module, each delivery outlet that described TVI turns HDMI module is connected with each display screen respectively by HDMI data wire.
The analog signal tablet of the technical program comprises: the multiple bnc interfaces connecting TVI signal input sources, connect multiple PCIE slots of motherboard respectively, be connected to the filter regulator circuit between each bnc interface and PCIE slot.Each analog signal tablet is respectively equipped with 16 bnc interfaces.TVI signal input sources comprises video camera, video tape recorder dome-type camera, integrated camera, infrared day and night video camera, high-speed ball camera, web camera.The chip signal that TVI turns HDMI module employing is TP2822 chip.Motherboard comprises the signal switching chip of band PCIE interface.
The direct switching that the utility model realizes many TVI simulation high-definition signal and many HDMI output interface exports, the access that super multiple TVI simulates high-definition signal is expanded by the mode of multimachine cascade, unified management, achieve input and the switching of multiple simulation signal generator simultaneously, after by conversion, realize direct HDMI display translation and can realize multiple HDMI output display TVI signal, also can realize any one TVI of any one HDMI Signal aspects and simulate high-definition video signal; Output of the present utility model, by the application of special chip function, directly can be with splicing to export, no longer need splicing controller etc., powerful; The utility model substituted for original traditional analog matrix, achieves the upgrading of simulation SD to simulation high definition with minimum cost and more simple work progress.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model one embodiment.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
The safety device of the inputted multichannel TVI signal that the utility model one embodiment proposes, comprises TVI signal input sources, display screen, the switching output module be connected with display screen by TVI signal input sources.
As shown in Figure 1, switch output module and comprise tertiary structure, the first order is analog signal tablet, this analog signal tablet carries out modularized design, each analog signal tablet is provided with 16 bnc interfaces, can access 16 TVI and simulate high-definition signal, connect 16 TVI signal input sources, then the output of each analog signal input module is also provided with the multiple PCIE slots connecting motherboard respectively, is provided with filter regulator circuit between each bnc interface and PCIE slot.
Then by multiple analog signal tablet access motherboard, the access-in management to all TVI signals is realized by the signal switching chip of motherboard, by the signal of PCIE interface incoming analog signal tablet, export TVI signal to TVI by PCIE interface again and turn HDMI module, by the signal switching chip on motherboard, analog signal tablet to be turned each input of HDMI module to TVI by each signal switching of PCIE interface access motherboard.By the handoff functionality on motherboard, by corresponding for an analog output channel one or more input channel, and analog signal is amplified by motherboard while switching, so just achieves the switching of the corresponding multiple modulating output of multiple analog input.
The second level is that TVI turns HDMI module, multiple TVI turns HDMI module and is connected with motherboard respectively, by motherboard, each TVI signal conversion is linked on the output interface of analog signal tablet of the first order, then by the conversion of TVI signal to HDMI, just realize the switching exported at the corresponding multiple HDMI of multiple simulation high-definition signal inputs, TVI turns the TP2822 chip that HDMI module have employed TechpointInc. company, TVI signal is converted to the HDMI signal of standard.
The third level is the output of HDMI signal, when not needing splicing function, directly TVI can be turned the display screen of the HDMI output interface access normal tape HDMI of HDMI module, by switching and the translation function of the first order and the second level, can be random by any input TVI HD video source display translation on required display screen.Because TVI turns the TP2822 chip band video segment function of HDMI module itself, when if desired splicing function, can take as under type realizes: utilize this chip multiple, each chip changes same video source simultaneously, then by a part for each chip controls display video, then multiple HDMI combines, and just can realize video-splicing function.
TVI signal input sources of the present utility model comprises video camera, video tape recorder dome-type camera, integrated camera, infrared day and night video camera, high-speed ball camera, web camera etc.
Above specific embodiment is only in order to illustrate design of the present utility model, and those of ordinary skill in the art can make various deformation and change under design of the present utility model, and these distortion and change include within protection range of the present utility model.
