Abstract
The invention discloses a recording system and a method based on active-standby and cache technology, wherein the recording system based on active-standby and cache technology comprises at least two control centers, namely, a main control center and a standby control center, which are connected with each other; the main control center and the standby control center are exchangeable, and the main control center is connected with one or a plurality of recording servers. The invention provides a recording system and a method based on active-standby and cache technology, wherein exchangeable main and standby control centers are utilized, if the main control centre occurs abnormality, the recording server continues to perform the recording tasks according to a virtual recording task list to avoid the data loss, and the standby control center immediately takes over the tasks of the main control centre to guarantee the normal work of the whole recording system, so that the recording server can normally work within a period even if the main and standby control centers have problems, which reduces the integral loss and improves the safety of the whole recording system.
Description
Technical field
The present invention relates to a kind of acceptance system, particularly a kind of acceptance system and method based on active and standby and caching technology.
Background technology
Along with the high speed development of broadcasting and TV cause to the digitlization direction; In industry, occupy more and more heavier status based on the service application of PC; Program is included as the important means of collecting the quarry, uses very extensively in business departments such as TV stations, and acceptance system is satellite-signal and other audio-video signals; Include to generate and look audio file; Can realize including focusing on of plan and task, realize unattendedly including automatically, and have advantage such as unit interface diversity; The front end signal interface supports various simulations to look COBBAIF (analog composite, component, Y/C), sdi signal and ASI interface (the TS stream signal that meets the DVB standard) etc.; The various files of looking audio format such as comprising MPEG21, MPEG2 IBP, DV, DV50, M-JPEG, WMV, MPEG4 can be exported in the rear end, and acceptance system can be realized the seamless link with network, realize the editor's while recording function; What acceptance system was pursued is high reliability and functions of redundancy and fault tolerance, handles thereby satisfy the round-the-clock continual signal task of including.
At present, if acceptance system commonly used is included control centre's machine when situation such as deadlock or fault, scheduler task are unusual occurring, include server and can't normally accept the task of including; Then whole acceptance system can't operate as normal; It is consuming time bigger that system-down is safeguarded, and can not guarantee control centre's machine maintenance well the back system data can not lose, if some precious system data is lost and can't be repaired; The integral body loss that brings is bigger, and the potential safety hazard of whole acceptance system is bigger.
Summary of the invention
The object of the invention promptly is to overcome the deficiency of prior art, provides a kind of employing interchangeable active and standby control centre, and main control centre occurs when unusual; Include server and continue to carry out the task of including according to the virtual job order of including; Avoid loss of data, and control centre takes over the main control centre task immediately fully, makes whole acceptance system operate as normal; Even active and standby control centre all goes wrong; Including server also can operate as normal in the certain hour section, reduces whole loss, improves the acceptance system and the method based on active and standby and caching technology of whole acceptance system fail safe.
The objective of the invention is to realize: based on the acceptance system of active and standby and caching technology through following technical scheme; It comprises at least two control centres; Two control centres are interconnective main control centre and are equipped with control centre; Main control centre is with control centre is interchangeable fully, and main control centre is connected with one or more servers of including.
Based on the recording method of active and standby and caching technology, it may further comprise the steps:
(1) the virtual job order of including of main control centre real time propelling movement is included server and is carried out the task of including to including server;
(2) be equipped with control centre and at regular intervals main control centre carried out heartbeat detection;
(3) unusual if main control centre occurs, include server and continue to carry out the task of including according to the virtual job order of including, be equipped with control centre and take over the main control centre task immediately, be equipped with control centre and upgrade to main control centre;
(4) normal if former main control centre recovers, detect the main control centre whether normal operation is arranged in the network automatically, if having; Then be downgraded to control centre fully automatically, and continue the current main control centre state of monitoring, if do not have; Then continue to serve as main control centre, scheduler task;
(5) continue execution and include task, until including task termination.
Described every part virtual include job order corresponding each include the task of server, comprise the task list after current time to 24 hour.
The invention has the beneficial effects as follows: the present invention provides a kind of acceptance system and method based on active and standby and caching technology, adopts interchangeable main control centre and is equipped with control centre, and active and standby control centre is detected mutually in real time; Occur when unusual at main control centre, include server and continue to carry out and include task according to the virtual job order of including, the work of guaranteeing is proceeded; Avoided loss of data; And be equipped with control centre and take over the main control centre task immediately, can upgrade the virtual job order of including again after the adapter, but manual intervention task executions; Make whole acceptance system ability operate as normal; Every part virtual includes the task list after corresponding each task of including server of job order comprises current time to 24 hour, even active and standby control centre all goes wrong, also can guarantee to include server can operate as normal in the certain hour section; Reduce whole loss, the fail safe that has improved whole acceptance system.
