Abstract
The utility model relates to a kind of vision signal lightning protection device with fault recovery function, comprise housing, housing has two power circuit binding post joints and two vision signal circuit binding post joints to external expansion, power lightning protection circuit and vision signal lightning protection circuit is provided with in housing, two power circuit binding post joints are connected by power lightning protection circuit, vision signal extension wire is also provided with in housing, two vision signal circuit binding post joints are switched to by respective diverter switch and are connected with vision signal lightning protection line circuit or are connected with vision signal extension wire circuit.Its internal signal circuit is provided with active and standby double-circuit, and when vision signal main line fault, fault-signal passes fault back Surveillance center and alert notification prompting by network.
Description
Technical field
The utility model relates to a kind of vision signal lightning protection device with fault recovery function.
Background technology
In recent years along with the security protection project such as " safe city ", " Safe Campus ", " peaceful community ", " harmonious China " is in nationwide Efforts To Develop and deep popularization, various place is extensively set up and is installed and used security protection video supervisory control system, rapid development the sector being obtained advance by leaps and bounds, and scale is constantly being doubled and redoubled.Video monitoring system is that definitely important effect is played in security protection work.But video monitoring system equipment is all the sensitive electronic equipment of collection precise electronic components and parts, and anti-lightning ability is very low, so video monitoring system equipment must install lightning protection device protection.Because each video monitoring system equipment disperses very much, the particularly video camera and trunking etc. of far-end, be distributed in each corner that need monitor especially, such as outdoor each street, highway, harbour, even away from the mining area, remote mountains etc. of residential area, if broken down, safeguard ageing very low.
And the current vision signal lightning protection device for video monitoring system is the all-in-one lightning arrester that collection power circuit and the lightning protection of vision signal circuit are combined into one.But to be struck by lightning or after surge impact failure at lightning protection device, video signal interruption will be caused and monitored picture interrupts, have a strong impact on monitoring effect, more do not allow to monitor the important events interrupted, can guarantee that the continuity monitored is particularly important, these are current supervisory control system video lightning protection device serious real defects in practicality.
Summary of the invention
The purpose of this utility model is to provide a kind of lightning protection device that vision signal can be recovered from fault.
In order to achieve the above object, the technical solution of the utility model there is provided a kind of vision signal lightning protection device with fault recovery function, comprise housing, housing has two power circuit binding post joints and two vision signal circuit binding post joints to external expansion, power lightning protection circuit and vision signal lightning protection circuit is provided with in housing, two power circuit binding post joints are connected by power lightning protection circuit, it is characterized in that: in housing, be also provided with vision signal extension wire, two vision signal circuit binding post joints are switched to by respective diverter switch and are connected with vision signal lightning protection line circuit or are connected with vision signal extension wire circuit.
Preferably, described housing has also extended out network communication interface and/or long-range remote signalling dry contact.
In the utility model; lightning protection device internal signal circuit is provided with active and standby double-circuit; when vision signal main line fault; fault-signal passes fault back Surveillance center and alert notification prompting by network; monitoring can be switched on reserve signalling link, guarantee monitor video signal recover immediately not interrupt or as far as possible break period short, and lightning protection device operation conditions can be known in time; can safeguard as early as possible when fault or deterioration, to try one's best, little risk allows watch-dog be in nonprotected state.
