A backup system is comprised of a main storage for storing original data and a plurality of local storages for distributing and storing the data. An encoding unit of the main storage server generates, after dividing the original data, a plurality of encoded data that is equal to or more than the dividing number by use of a code of which redundancy is variable. A distribution processing unit distributes the plurality of encoded data to the plurality of local storages, and causes the data to be stored therein. A restoring unit retrieves the encoded data corresponding to at least the division number of the original data from the local storages, and restores the original data. A redundancy control unit varies the redundancy in the encoding unit such that, the higher the importance of the data, the larger the redundancy. Furthermore, a distribution processing unit determines the distribution number such that the higher the reliability of the local storages, the more the number.

The invention relates to a control system for a bridge cable detection robot, which includes a host computer, a motion control unit and a wireless communication unit. The motion control unit includes a main controller, a driver, a position and speed control module, and a sensor detection module. The unit sends the control signal to the main controller, the main controller is connected to the driver, the driver is connected to the robot through the position and speed control module, the sensor detection module monitors the speed, direction of travel and travel range of each wheel of the robot in real time, and detects The obtained signal is sent to the main controller, and the main controller compares this signal with the signal sent by the host computer to form a control error signal, which is fed back to the driver, and the driver adjusts the robot to form a closed-loop control of the robot. Compared with the prior art, the invention has the advantages of high control precision, high work efficiency, enhanced self-adaptive ability, good stability and the like.

The invention relates to an automatic sizing and cold shearing method and an automatic sizing and cold shearing device. The method includes: starting a cold bed output roller table, a pre-shearing roller table and a first after-shearing roller table to transport to-be-sheared steel; enabling a sizing baffle to fall down when the fact that the to-be-sheared steel passes through the first after-shearing roller table is detected; controlling the to-be-sheared steel to stop at the position of the sizing baffle; shearing the to-be-sheared steel when a shearing order is received; lifting the sizing baffle; after sheared finished steel products on a second after-shearing roller table are transported to a set distance, starting the first after-shearing roller table to transport the sheared steel from the first after-shearing roller table to the second after-shearing roller table. The steel on the roller tables is positioned by area sensors, and positioning parameters can be set and adjusted on a picture. Buttons, needed to be operated in actual production, of an operation table are greatly reduced, and consequently working and production efficiency can be improved.

The invention relates to the technical field of computers, in particular to a Genesys calling system high-availability cloud computing system and method. According to the Genesys calling system high-availability cloud computing system and method, a calling system is planted into a cloud end and the problem of rapid back-up and recovery of a calling service is mainly solved. The calling system utilizes an incident communication mechanism to carry out communication. According to a frame structure of the system, the calling system is divided into a scheduling layer, a logic layer and a function layer. The scheduling layer is mainly responsible for operating an overall situation incident queue and can ensure that all the incidents can be performed orderly. The logic layer is a decider of the whole system and is responsible for deciding a processing and operating process of the incidents. The function layer is the bottommost layer of the whole system and is mainly responsible for interacting with a management platform of a virtual machine and providing support for the previous layers. The Genesys calling system high-availability cloud computing system and method have the advantages that constant safety assurance can be provided for the Genesys calling system, the problem of excessive loads of the Genesys calling system is solved and stable and reliable operation of application services can be ensured.

The invention discloses a method for establishing a VNF, NFVO and a network system, and relates to the field of communication technology. The method includes: NFVO requests VIM to allocate virtual resources, and when it is judged that an abnormal situation occurs, NFVO sends an instruction to create a VNF instance to VNFM, Assign permission to create VNF instances; VNFM requests VIM to allocate virtual resources for creating VNF instances and create VNF instances. In the establishment method, NFVO and network system of the present invention, a VNF instance is established in the indirect mode, and the direct mode is used as the backup mode in case of failure. When the indirect mode is executed to establish the resource call of the VM to fail, it will automatically sense and switch to the direct mode to complete The resource call created by the VM, and the subsequent automatic establishment and monitoring operations increase the fault recovery capability of the indirect mode, and the changes to the NFV architecture are small, which is beneficial to the actual operation of the live network.

The invention discloses an electric power big data storing method capable of dealing with N-5 storage medium failure. The method includes the steps of constructing a data communication network, distributing a data storage unit, storing data and polling and dealing with failure. The operation method is simple, reliable, high in operation automation degree and capable of effectively finding operation failure of a storage device in time on one hand and effectively improving failure resisting capacity and repairing capacity of the storage device on the other hand to effectively improve operation stability and reliability of an electric power big data storage system and avoid data loss.

The invention discloses a state self-adaptive method of a non-PRF interface, applied to the state self-adaptive adjustment of the non-PRF interface generating Assert in PIM-DM group network, which includes that: implementing the state identification on a delivering interface of a state refreshing message based on the state refreshing message received by the non-RPF interface; if the delivering interface is in the state that Assert does not occur, synchronizing the non-RPF interface to the state that Assert does not occur. The invention also discloses a state self-adaptive device of the non-RPF interface and a kind of switching equipment. The method, the device and the equipment in the invention reduce the duplication and the forwarding of the messages in the upstream equipment, prevent the downstream equipment processing the illegal message, thereby enhancing the processing ability of the equipment, increasing the bandwidth usage rate, decreasing the bandwidth waste, and improving thewhole processing ability and the fault recovery ability of multicast domain.
