Description
Technical field
The present invention relates to a kind of DVR hot backup system and device, refer more particularly to a kind of DVR hot backup system and device that is applied to protection and monitor field.
Background technology
The application of computer technology and universal, the fast development of the communication communication technology, image Compression technology and transmission technology, make the safety precaution industry can adopt up-to-date computer, communication and image processing techniques, by computer communication transmission of digital image, can be and realize that remote image monitoring, speech talkback and linkage alarm device provide efficient, feasible solution.Along with the extensive use of broadband technology and digital video technology, the digital monitoring technology that adopts live multicast (broadcasting) of digital video and monitoring module to combine is for remote monitoring provides completely new concept and more wide space.
It is current that to use more at the communication monitoring technique be hard disk computer communication supervisory control system, what mainly adopt is digital recording, also is far superior to other watch-dogs at aspects such as image processing, image storage, prison rope, backup and communication transmission, Long-distance Control.But because the fault of hard disk and power-supply device is comparatively frequent, and hard disk itself is limited useful life in actual application, can occur in the course of the work that magnetic track damages or aging; In case the operating state of part video tape recorder occurs unusually in the supervisory control system, then the resulting information of guarded region can't in time write down and store, and causes the whole digital information system can not complete reflection actual conditions, also just can't ensure monitoring effect.
Summary of the invention
At the defective that above-mentioned technology exists, the present invention proposes following corrective measure: be provided with monitoring modular and monitoring port in the device, described monitoring modular is connected with monitoring port; Also be provided with the switching controls module in the device, described switching controls module is connected on matrix exchanger and the backup video tape recorder by PORT COM.
Described monitoring modular is connected with host computer by communication interface with the switching controls module.
Described monitoring modular and switching controls module are directly arranged on DVR or the matrix exchanger.
A kind of DVR hot backup system of using the DVR heat backup device, comprise hard disc recording unit, communication system, matrix exchanger, described hard disc recording unit comprises conventional video tape recorder and at least one 's standby video tape recorder, and it is characterized in that: described DVR hot backup system also comprises a heat backup device that is provided with monitoring modular and switching controls module.Described heat backup device is connected with hard disc recording unit, matrix exchanger, and constantly monitors the operating state of hard disc recording unit by monitoring modular; In case finding certain conventional video tape recorder operating state occurs when unusual, send command adapted thereto by the switching controls module to matrix exchanger, output signal on the corresponding matrix exchanger of problem video tape recorder is switched on the standby video tape recorder, open standby video tape recorder simultaneously and keep continuing video recording.
The monitoring modular of described heat backup device all is connected with host computer with the switching controls module, and described host computer is any in independent PC terminal management device or the built-in terminal.
The monitoring modular of described heat backup device and switching controls module are located on any DVR.
The monitoring modular of described heat backup device and switching controls module are located on the matrix exchanger.
Described heat backup device sends alarm signal by system's control.
Host computer is a system administration manager, mainly is responsible for initialization system parameter, executive system routine and management system component.
In system's running, monitoring modular constantly detects on the conventional video recording unit parameter ruuning situation on every DVR under the executive program control in host computer.
The function of switching controls module is mainly reflected in following two aspects: one, open standby video tape recorder under the executive program control in host computer; Two, in host computer, under the executive program control output signal on the corresponding matrix exchanger of problem video tape recorder is switched on the standby video tape recorder.
Communication system can adopt local area network (LAN) or the wide area network that comprises Ethernet, also can adopt communication modes such as RS-485, RS-422, RS-232.What employing was more at present is Ethernet system, can be connected to LAN or WAN hub or switch, realizes TCP/IP Ethernet controlled function.Connect by Ethernet, every matrix exchanger can both be switched any matrix exchanger image in the communication and control.
The matrix exchanger interchanger has multi-channel video input, multi-channel video output and a plurality of control terminal.Its video inputs connects the video signal source of each DVR input on the conventional video recording unit, and video output terminals is connected on the standby video tape recorder.
The hard disc recording unit comprises conventional video tape recorder and standby video tape recorder, mainly adopts communication type embedded hard disc video tape recorder.
The operation principle of DVR hot backup system is as follows: host computer is by the program software of execution heat backup device and the running parameter of initialization system, and the control monitoring modular constantly detects the operating state of every DVR on the conventional video recording unit; In case finding certain conventional video tape recorder operating state occurs when unusual, host computer sends command adapted thereto by the switching controls module to matrix exchanger, output signal on the corresponding matrix exchanger of problem video tape recorder is switched on the standby video tape recorder, open standby video tape recorder simultaneously and keep continuing video recording; And send the ALM signal.
The present invention has dealt carefully with image transmission and the system data disruption that occurs based on the DVR unstable working condition, with the combining of digital technology and communication system, has the regional wide advantage of deploying to ensure effective monitoring and control of illegal activities simultaneously.Adopt unified agreement in communication, to transmit simultaneously, support inter-network to close, stride the long-distance video transmission of router; Video server and communication type embedded hard disc video tape recorder are in fact based on the inserted computer technology, adopt the embedded real-time multitask operating means, directly be connected into local area network (LAN) or wide area network, promptly insert and promptly see, real-time, stability, the reliability of device improve greatly, need not the personal management simultaneously, be very suitable for unattended environment.
