Description
Technical field
The utility model relates to pilot signal anti-interference equipment in a kind of security protection construction, particularly relates to a kind of video suppressor.
Background technology
At present, along with the quickening of urban digital development process, railway station, area, bus station in the city; Road, street and community; Digital monitoring equipment has all been installed in places such as the corridor of commercial affairs building, elevator, is used for the monitoring of social security or disaster accident.But because the restriction of the problems of geographical environment, equipment performance and circuit transmission etc.; And the interference of elevator, transformer station, large scale electrical power unit etc.; Also because the vision signal of video camera output is a composite video, the reason that in transmission course, is interfered easily causes the signal quality of watch-dog often unsatisfactory; Image display effect is not very desirable; The effect of watch-dog can not be given full play to, and because the existence of these problems has brought various unnecessary troubles also for construction and unit in charge of construction.Perhaps solve such problem that has existed in the engineering for fear of these problems, the technical staff has designed various vision signal means for anti-jammings, to solve the relatively poor problem of supervisory control system effect that causes owing to poor signal quality.But and in the actual use, because camera or modulation and demodulated equipment all need power supply adaptor, this just makes each equipment all need connect a power supply adaptor, and wiring is inconvenient, needs porous socket, in case loose contact also is out of order easily.Therefore, no matter be to start from purpose easy to install or take into full account the demand that the client practices thrift cost, all need carry out useful improvement to existing design.
The utility model content
The utility model is not enough to prior art; A kind of video suppressor that has the power ring outgoing interface is proposed; On the housing of transmitting terminal and/or receiving terminal, be connected with the power ring outgoing interface with said power input interface circuit; During use suppressor can with the shared power supplys of other 12v power supply unit such as video camera, convenient construction is also practiced thrift cost.
The technical scheme that the utility model adopted:
A kind of video suppressor that has the power ring outgoing interface; Comprise transmitting terminal and receiving terminal; Said transmitting terminal is provided with video signal input interface, radiofrequency signal output interface and power input interface; Receiving terminal is provided with radiofrequency signal input interface, video signal output interface and power input interface; Be connected with power supply voltage stabilizing treatment circuit at transmitting terminal or receiving terminal or transmitting terminal and receiving terminal with said power input interface; Said transmitting terminal and receiving terminal adopt all aluminium alloy closure, and the parallelly connected power ring outgoing interface that is provided with said power input interface in power input interface one side end face is set on the shell of said transmitting terminal or receiving terminal or transmitting terminal and receiving terminal.
The described video suppressor that has the power ring outgoing interface, power input interface and said power ring outgoing interface adopt the DC supply socket of standard.
The described video suppressor that has the power ring outgoing interface, transmitting terminal and receiving terminal respectively are provided with lightning protection circuit, connect a gas discharge tube over the ground at the RF signal input end mouth of receiving terminal or the radiofrequency signal output port of transmitting terminal.
The useful good effect of the utility model:
1, the utility model video suppressor; Take into full account the demand that the client practices thrift cost in the design; On the housing of transmitting terminal and/or receiving terminal, be connected with the power ring outgoing interface with said power input interface circuit; When installing and using the video suppressor can with the shared power supplys of other 12v power supply unit such as video camera, with convenient construction and practice thrift cost.
2, the utility model video suppressor cabinet adopts all aluminium alloy closure, can better avoid equipment to be had influence on anti-interference effect by interference.The lightning protection circuit design adopts a gas discharge tube that the forceful electric power pressure of outside, big electric current are released, thereby effectively reduces the damage of equipment.
Description of drawings
Fig. 1: the utility model video suppressor transmitting terminal or receiving terminal shell structure;
Fig. 2: the power ring outgoing interface on the utility model video suppressor housing is arranged sketch map;
Fig. 3: the power ring outgoing interface circuit theory diagrams of the utility model video suppressor.
Embodiment
Embodiment one: referring to Fig. 1, Fig. 2, Fig. 3.The utility model has the video suppressor of power ring outgoing interface; Comprise transmitting terminal and receiving terminal; Said transmitting terminal is provided with video signal input interface, radiofrequency signal output interface and power input interface; Receiving terminal is provided with radiofrequency signal output interface, video signal output interface and power input interface; Be connected with power supply voltage stabilizing treatment circuit at transmitting terminal or receiving terminal or transmitting terminal and receiving terminal with said power input interface; Said transmitting terminal and receiving terminal adopt all aluminium alloy closure, and power input interface one side end face and the said power input interface 3 parallelly connected power ring outgoing interfaces 4 that are provided with are set on the shell 1 of said transmitting terminal or receiving terminal or transmitting terminal and receiving terminal.
Among Fig. 1, power input interface and the power ring outgoing interface installing hole of label 2 for offering on the housing, Fig. 2 are that interference unit housing one side power input interface and power ring outgoing interface are arranged sketch map.Said video suppressor, power input interface 3 and power ring outgoing interface 4 all adopt the DC supply socket of standard.Fig. 3 is that the power input interface and the power ring outgoing interface of video suppressor is electrically connected schematic diagram.Two DC supply socket J1, J2 are connected in parallel among the figure, and one is power input interface, and one is the power ring outgoing interface.
When video suppressor is is before installed and used; All need the power supply of a 12V with front-end camera; Therefore need two power supply adaptors, the supply socket of single hole is difficult to satisfy instructions for use, also receives the restriction of outdoor water-proof case space size simultaneously when mounted.The utility model one is from cost consideration; The 2nd, can not receive the restriction of the space size of outdoor water-proof case when mounted; In use, only need original 12V power supply is connected to (power input interface) on the suppressor earlier, be communicated with by the power ring outgoing interface of suppressor power supply again video camera; Practice thrift the engineering construction cost, also need not to change the design of outdoor water-proof case.
The utility model video suppressor in conjunction with actual environment for use, can design lightning protection circuit, connects a gas discharge tube over the ground at the RF signal input end mouth of receiving terminal or the radiofrequency signal output port of transmitting terminal.Adopt a gas discharge tube that the forceful electric power pressure of outside, big electric current are released, thereby can effectively reduce the damage of equipment, ensure the normal use of video suppressor.
