Description
Technical field
This utility model relates to closed-circuit television fault detection technique field, particularly relates to a kind of cctv surveillance system
System.
Background technology
It is known that closed-circuit television Closed Circuit Television (CCTV) is a kind of image communication system.Its
Signal only passes to the fixed particular television communicated with source point from source point.It is widely used in a large amount of different types of supervision
Work, education, video conference etc.；Closed-circuit television is broadcasted comparatively speaking with television station OCTV.Broadcast point radio broadcasting
With wired broadcasting two kinds, the ABC air broadcast of television station is equivalent to radio broadcasting (user obtains TV signal from antenna), closed circuit electricity
Depending on being then equivalent to wired broadcasting (cable television pattern: TV signal is sent to specify user by cable) from satellite transmission ends.
It is to transmit TV signal by wire.It is mainly and audio-video signal is transformed into a certain radiofrequency signal (the most a certain channel),
So could transmit in closed-circuit television system.Closed-circuit television generally refers to the TV beyond broadcast, such as industrial television, army
With TV, medical television, underwater television etc..
At present, in the middle of the use process of closed-circuit television, television reception terminal can break down sometimes, above-mentioned in order to solve
Fault, the scheme that legacy user uses is to notify fault message, to management personnel or maintainer, to wait management personnel
Or the maintenance of visiting of maintainer；It is clear that this traditional maintenance mode needs to expend the regular hour, greatly
The vital interests of user are had influence on；Therefore, design and develop one and fault can be carried out far-end detection, and then improve maintenance effect
The closed-circuit TV monitoring system of rate seems it is particularly important.
Utility model content
The technical problems to be solved in the utility model is: provide a kind of closed-circuit TV monitoring system, this cctv surveillance
Television terminal can remotely be detected, and then improve the efficiency of maintenance by the way of remotely monitoring by system.
This utility model is adopted the technical scheme that by solving technical problem present in known technology:
A kind of closed-circuit TV monitoring system, described closed-circuit television includes control centre, signal transmitted data line and multiple
Television reception terminal；Described control centre is attached with each television reception terminal by signal transmitted data line；Its feature
It is: described monitoring system at least includes:
Every television reception terminal of closed loop TV is at least installed a photographic head and an audio collection card；Described
Photographic head is for gathering the video image information that television reception terminal is play, and described audio collection card is used for gathering television reception
The audio-frequency information that terminal is play；Each photographic head and each audio collection card carry out data friendship by repeater and monitor terminal
Change；
With the handheld terminal that monitor terminal carries out data exchange；Described handheld terminal carries out electricity by data wire and repeater
Connect.
Further: also to include for controlling each photographic head and the electrical switch of each audio collection card duty；Often
Individual electrical switch is electrically connected with repeater by data wire.
This utility model has the advantage that with good effect:
By using technique scheme, when television terminal sends fault, staff can by monitor terminal or
Person is that handheld terminal extracts photographic head and the data of audio collection card in time, and then to on-the-spot video signal and acoustical signal
It is analyzed judging, thus improves the work efficiency of maintenance；Simultaneously as this patent is provided with electrical switch, therefore TV is eventually
When end does not break down, photographic head and audio collection card are closed modes, the most both can extend its service life, other one
Aspect also protects the privacy of user.
Accompanying drawing explanation
Fig. 1 is the circuit block diagram of this utility model the first preferred embodiments；
Fig. 2 is the circuit block diagram of this utility model the second preferred embodiments.
Detailed description of the invention
For utility model content of the present utility model, feature and effect can be further appreciated that, hereby enumerate following example, and
Accompanying drawing is coordinated to describe in detail as follows:
Referring to Fig. 1, a kind of closed-circuit TV monitoring system, described closed-circuit television includes control centre, signal transmitted data
Line and multiple television reception terminal；Described control centre is carried out with each television reception terminal by signal transmitted data line
Connect；Described monitoring system includes:
Every television reception terminal of closed loop TV is at least installed a photographic head and an audio collection card；Described
Photographic head is for gathering the video image information that television reception terminal is play, and described audio collection card is used for gathering television reception
The audio-frequency information that terminal is play；Each photographic head and each audio collection card carry out data friendship by repeater and monitor terminal
Change；
With the handheld terminal that monitor terminal carries out data exchange；Described handheld terminal carries out electricity by data wire and repeater
Connect.
The operation principle of this preferred embodiment is: when television reception terminal breaks down, user sends to maintainer
Detection request, maintainer receives photographic head and the data of audio collection card by monitor terminal or handheld terminal, and then
The malfunction of television reception terminal it is analyzed and judges, and indicating user to carry out the investigation of simple fault；The most permissible
It is greatly enhanced the efficiency of maintenance.
Referring to Fig. 2, a kind of closed-circuit TV monitoring system, described closed-circuit television includes control centre, signal transmitted data
Line and multiple television reception terminal；Described control centre is carried out with each television reception terminal by signal transmitted data line
Connect；Described monitoring system includes:
Every television reception terminal of closed loop TV is at least installed a photographic head and an audio collection card；Described
Photographic head is for gathering the video image information that television reception terminal is play, and described audio collection card is used for gathering television reception
The audio-frequency information that terminal is play；Each photographic head and each audio collection card carry out data friendship by repeater and monitor terminal
Change；
With the handheld terminal that monitor terminal carries out data exchange；Described handheld terminal carries out electricity by data wire and repeater
Connect；
For controlling each photographic head and the electrical switch of each audio collection card duty；Each electrical switch passes through
Data wire electrically connects with repeater.
The operation principle of this preferred embodiment is: when television reception terminal breaks down, user sends to maintainer
Detection request, opens the power supply of electrical switch simultaneously, and maintainer receives photographic head by monitor terminal or handheld terminal
With the data of audio collection card, and then the malfunction of television reception terminal it is analyzed and judges, and indicating user to carry out
The investigation of simple fault；So can be greatly enhanced the efficiency of maintenance.Meanwhile, when television reception terminal does not breaks down,
User manually closes the power supply of electrical switch, and now, maintainer cannot open electrical switch by the way of long-range, this
Sample both can extend photographic head and the life-span of audio collection card, and still further aspect protects the privacy of user.
Above embodiment of the present utility model has been described in detail, but described content be only of the present utility model preferably
Embodiment, it is impossible to be considered for limiting practical range of the present utility model.All according to this utility model application range made equal
Deng change and improvement etc., within all should still belonging to patent covering scope of the present utility model.
