Embodiment Construction
[0045]As shown in FIG. 1 , it is a schematic structural diagram of a device board protection device according to an embodiment of the present invention. The equipment board protection device consists of four parts: a control unit 101 , a working board 102 (with several working boards), a spare board 103 and a communication bus 104 . The control unit 101 is the core of the entire system, sending work content, configuring protection information, and issuing protection instructions. The work board 102 realizes the work content, and the control unit 101 issues the work content, and the work board 102 stores the work content, and works according to the work content. The work content of each job board may be different, and the work content may change at any time according to configuration changes. The storage area in the standby board 103 is divided into many sections, and each section stores the work content of a working board. When receiving the work content of any working board,...

The invention provides an equipment veneer protection device and the protection methods thereof comprising a control unit, a working plate, a reserved panel and a communication bus. The control unit is connected with the working plate and the reserved panel through the communication bus of a parallel model. When the control unit sends off information, the working plate and the reserved panel receives completely the same information simultaneously. The procedures of the methods are as follows: (1) the control unit sends off information to the working plate and the reserved panel simultaneously to build up a protective relationship; (2) the control unit sends of information simultaneously and the working plate works according to the received content and the reserved panel saves the received content; (3) when in fault, the control unit sends off information simultaneously and the reserved panel replaces the fault working panel to work. The invention and the methods thereof can reduce the information quantity of the communication and the occupation on the bus resources thus avoiding obstruction of communication and increasing the working efficiency. Meanwhile, the protection starting time can be reduced and the affects of the fault on normal service is also reduced.
Description
technical field [0001] The invention relates to the technical field of fault protection of electronic communication equipment, in particular to a protection device and method between working boards in communication equipment. Background technique [0002] In important equipment, especially communication equipment, it is often necessary to take protection measures to improve the reliability of the equipment. Inter-board protection is a reliable protection method. When a working board fails, another spare board is used for protection immediately. The working board replaces the working board to ensure the normal operation of the equipment. In addition to protecting the working board, the standby board also requires fast protection speed and reduced interruption time. [0003] The protection between working boards is a device-level protection mode, that is, when the working board fails, the standby board can be used to replace the working board. How to reduce the time of the p...
