The utility model discloses replaced original tradition simulation matrix, not only powerful realizes moreover that the simulation mark is clear with the upgrading of minimum cost to the simulation high definition.
Description
Technical field
The utility model relates to security device.
Background technology
In safety-security area, the full name of AHD is AnalogHighDefinition, looks like for simulation high-res.Existing AHD video camera can realize 720P, 960P even the HD video resolution of 1080P.
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 multi-channel A HD signal is provided, comprise AHD signal input sources, display screen, the switching output module that AHD signal input sources is connected with display screen, described switching output module comprises at least one for accessing the analog signal tablet of multi-channel A HD signal, at least one AHD multi-channel A HD signal being converted to the output of HDMI signal turns HDMI module, the output signal of each analog signal tablet is switched to the motherboard that AHD turns the input of HDMI module, each delivery outlet that described AHD turns HDMI module is connected with each display screen respectively by HDMI data wire.
Further, each analog signal tablet is respectively equipped with 16 bnc interfaces.The chip signal that AHD turns HDMI module employing is NVP6124_128eTQFP_SOCKET chip.AHD 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 utility model is by carrying out modularized design by simulation switching matrix device, achieve the access that multiple AHD simulates high-definition signal, achieve input and the switching of multiple simulation signal generator simultaneously, after by conversion, realize direct HDMI display translation, and AHD turns HDMI module by adopting special chip, splicing can be directly with to export, no longer need splicing controller etc., achieve the upgrading of powerful simulation SD to simulation high definition by less cost, simpler production process.
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 multi-channel A HD signal that the utility model one embodiment proposes, comprises AHD signal input sources, display screen, the switching output module be connected with display screen by AHD 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 AHD and simulate high-definition signal, connect 16 AHD 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 AHD signals is realized by the signal switching chip of motherboard, by the signal of PCIE interface incoming analog signal tablet, export AHD signal to AHD 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 AHD 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 AHD turns HDMI module, multiple AHD turns HDMI module and is connected with motherboard respectively, by motherboard, each AHD signal conversion is linked on the output interface of analog signal tablet of the first order, then by the conversion of AHD signal to HDMI, just realize the switching exported at the corresponding multiple HDMI of multiple simulation high-definition signal inputs, AHD turns HDMI module and have employed NVP6124_128eTQFP_SOCKET chip, AHD signal is converted to the HDMI signal of standard.
The third level is the output of HDMI signal, when not needing splicing function, directly AHD 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 AHD HD video source display translation on required display screen.Because AHD turns the NVP6124_128eTQFP_SOCKET 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.
AHD 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.
