Abstract
The aim of the present invention is to provide a reliable digital recorder group controlling system which is composed of a video distributor, a control host machine, a digital recorder group, a spare digital recorder and a group of video switchers. A few or one device is needed to obtain the redundancy of all digital recorders to achieve recording with multiple digital recorders; the central control of the recorder group is achieved so as to enhance the security of the system.
Description
Technical field
The present invention relates to electronic equipment, especially cluster video recording equipment control is suitable for the occasion that many digital video recording equipment are concentrated placement and video recording is had relatively high expectations.
Background technology
Owing to the demand to safety increases, various occasions all are equipped with video recording equipment, particularly digital video recording equipment in recent years.Present applicable cases is that the isolated use of single device or many simple superposition are used, if in case have unexpected word the, the consequence that will cause video recording to lose; So for the very important occasion of part, adopted the mode of 1 pair 1 redundancy of digital video recording equipment to realize reliable preservation, reliability is to guarantee like this, but equipment investment is excessive.
Summary of the invention
The purpose of this invention is to provide a kind of reliable digital VTR group control system, only need adopt a small amount of several or 1 equipment can realize redundancy when realizing the video recording of many digital VTRs to whole digital video recording equipment, realize the video tape recorder middle control of trooping simultaneously, increased security of system.
The present invention is made of following equipment: video distributor, main control system, a digital recording group of planes, backup digital VTR and group video switcher.Each equipment carries out communication in a main control system timing (for example can be set at 1s) and the digital recording group of planes in this system, with situation that wherein the some number of times of a certain equipment (faulty equipment) (for example being set at 3 times) do not contact under, and this equipment is should be in video state the time, main control system control group video switcher outputs to the backup digital VTR with the vision signal of faulty equipment correspondence, starts the backup digital VTR simultaneously and records a video; After main control system detected the recovery normally of fault machine, the digital VTR of control backup at once stopped to record a video and being in treating the writ attitude.The time of so can safeguards system losing video recording remains on minimum, and the cost of system is reduced greatly.
Description of drawings
As shown in drawings, native system is made of video distributor 1, main control system 2, group video switcher 3, backup digital VTR 4, a digital recording group of planes 5.
Embodiment
The present invention will be described below in conjunction with system diagram:
1, before system puts into operation, by main control system the video recording rule (video recording mode and time) of each video tape recorder of digital VTR group is set, all needed by main control system change (assurance system safety) in the change of any video-recorder recording rule of run duration.
2, video distributor is divided into two-way with the vision signal of each front-end camera, one tunnel grouping enters into a digital recording group of planes and records a video for a long time, other one the road enters into the group video switcher, the group video switcher video output insert the backup digital VTR.Main control system is connected with a digital recording group of planes, group video switcher and backup video tape recorder respectively by control interface.Each equipment is got in touch in a main control system timing and the digital recording group of planes, if find wherein any one occur accident repeatedly (can set) do not have the contact situation under, and this equipment should be under the video state (video time satisfies or mode satisfies), the group of control at once video switcher outputs to the backup digital VTR with one group of vision signal of faulty equipment correspondence, simultaneously the video recording Control Parameter of fault video tape recorder is downloaded to the backup video tape recorder, control backup video tape recorder begins to start video recording, control backup video tape recorder is superimposed with fault video recording plane No., date and time (so that inquiry convenient) afterwards, and with relevant information records in the main control system database.After if main control system detects the faulty equipment recovery, after repeatedly (can setting) normal communication, the control backup host stops video recording and is in treating the writ attitude, and relevant information also is recorded in the main control system database.
Claims (2)
1, a kind of digital VTR group control system, form by video distributor, main control system, a digital recording group of planes, backup digital VTR and group video switcher, it is characterized in that: video distributor is divided into two-way with the vision signal of each front-end camera, one tunnel grouping enters into a digital recording group of planes and records a video for a long time, other one the road enters into the group video switcher, the group video switcher video output insert the backup digital VTR; Main control system by control interface respectively with a digital recording group of planes, the group video switcher is connected with the backup digital VTR, each digital VTR is got in touch in a main control system timing and the digital recording group of planes, if finding wherein any digital VTR occurs under the unexpected situation that does not repeatedly have to get in touch, and the unexpected digital VTR that does not repeatedly have to get in touch of appearance is under the video state, accident will appear in main control system control group at once video switcher does not repeatedly have one group of vision signal of the digital VTR correspondence of contact to output to the backup digital VTR, to occur accident does not simultaneously repeatedly have the video recording Control Parameter of the digital VTR of contact to download to the backup digital VTR, control backup digital VTR begins to start video recording, and the unexpected digital recording plane No. that does not repeatedly have contact appears in the stack of control backup digital VTR, date and time, and with relevant information records in the main control system database, after if main control system detects and the unexpected digital VTR recovery that does not repeatedly have to get in touch occurs, through behind the normal communication repeatedly, control backup digital VTR stops video recording and is in treating the writ attitude, and relevant information also is recorded in the main control system database, only need adopt a small amount of several or 1 backup digital VTR can realize backup when so realizing many digital VTRs video recordings to whole digital VTRs, realize the digital VTR middle control of trooping simultaneously, increased security of system.
2, the desired digital VTR group control system of claim 1, it is characterized in that: before system puts into operation, need set the video recording rule of each digital VTR of digital VTR group by main control system, all need to change by main control system in the regular change of any digital VTR video recording of run duration.
