The method includes following steps: after receiving request for changing cross connections, configuration controller calculates request so as to obtain new CLOS matrix; configuration controller issues new CLOS matrix to group of cross node; waiting for ready signal returned from all cross nodes in group of cross node; after ready for preparing switching, each cross node returns ready signal to configuration controller; after all ready signals are returned, configuration controller sends out synchronous switching signal to inform each cross node to carry out switching operation for the cross matrix; after receiving 'synchronous switching signal' from configuration controller, each synchronous node switches to new matrix instantly. Configuration controller is composed of communication circuit, control line and state line.

The invention provides an operation intercept based repentance method of a distributed critical task system, comprising the following steps of: firstly carrying out redundancy backup on important files of the system to ensure the recoverability of data information; secondly intercepting the operation information of the system by an operation intercepter in real time and writing into an operation log; and analyzing captured operation records by an operation analyzer and writing unrecoverable operation or operation which does not need to be recovered into redundant files by an operation storageand processing the operation which needs to be recovered by a repenter. When the system is faulty, the repenter carries out repentance recovery on the system through three continuous steps of operation rollback, operation restoration, operation resetting and solves the problem of inconsistency possibly generated in the repenting process through a consistency manager according to a graded compensation strategy.

The invention discloses a data backup method, system, device and storage medium under a private cloud architecture. The method includes the following steps: backing up the data of the management node every predetermined time, and backing up the data with the same name in chronological order Cyclic coverage; in response to the completion of the backup, start the backup receiving service; transfer the backup data to the local disk based on the backup receiving service, and transfer the backup data to the first and last reachable nodes in the private cloud based on the IP rule; and respond to When the management node fails, it sends data recovery requests to the local disk, the first and last reachable nodes, and receives backup data. The method, system, equipment and medium for data backup under the private cloud architecture proposed by the present invention transmit the backup data to the local, first and last reachable nodes respectively in the private cloud architecture to ensure data security to the greatest extent .

The invention relates to IP (Internet Protocol) centralized dictation system and method. The IP centralized dictation system comprises an MGCP (Media Gateway Control Protocol) dictation module, a dictation management module, an information transmitting module, a dispatch terminal communication module and a magnetic disc management module, wherein the dictation management module comprises a dictation submodule, an information processing submodule, an audio alarm submodule, a dual-computer hot standby submodule and an interface management submodule. The IP centralized dictation method comprisesthe following steps of: starting a main program; acquiring operating parameters of the IP centralized dictation system, which include channel relevant parameters, magnetic disc pack information, and the like; acquiring an IP address and a port number of an information transmitting server, and connecting; dispatching an MGCP dictation library, and initializing the MGCP dictation library; dispatching a magnetic disc management library to carry out the automatic management of the magnetic disc; dispatching the dispatch terminal communication module to carry out communication by connecting with adispatch terminal; and judging whether a dual-computer hot standby working mode is adopted or not. The IP centralized dictation system which realizes the dictation of an analog telephone registered to a dispatcher, a digital telephone and an MGCP telephone has the advantages of simple installation, good tone quality, convenient inquiry and flexible playing.

The invention discloses a positioning device and a construction method for a composite supporting structure, comprising a water-stop curtain located around the bottom of a foundation pit, a core pile connected in the water-stop curtain, and a hoisting assembly connected to the core pile; The bottom end of the core pile is higher than the bottom end of the water-stop curtain, and an anchor cable is also connected between the core pile and the surrounding soil; the water-stop curtain is located at the toe of the slope protection slope, and its inner side is close to the edge line of the toe of the slope. Through the three-dimensional modeling in the early stage, the invention is conducive to deepening and controlling the construction of the composite supporting structure and the positioning components, and the positioning components can effectively ensure the positioning of the core piles in the later stage; by inserting the core piles in the stirring piles, it is beneficial to strengthen the water-stop curtain, In addition, the length of the core pile is less than the height of the water-stop curtain, which saves the construction cost while ensuring the strength. The slope protection is used to connect the positioning components for the bearing system, and combined with the setting of the pile positioning frame and its connected sliding components, it is possible to carry out the construction of small sites. The hoisting positioning on the upper part further ensures the convenience and accuracy of construction.
