Embodiment

[0037] This embodiment: as figure 1 As shown, a field data information security control method of a distributed centralized control system includes: a conflict handling mechanism;

[0038] The conflict handling mechanism includes:

[0039] If the transaction operates S101 on the data item, first apply for the lock control authority of the corresponding data item S102, if within the corresponding lock control period, apply for the lock control authority of the corresponding data item successfully S103, then lock the corresponding data item Process S104, if the corresponding data item is locked and process S106, then perform operation S107 on the corresponding data item, if the corresponding data item operation is completed S108, then release the corresponding lock control period for the corresponding data item Lock and control authority of the data item and perform unlocking process S109.

[0040]Because if the transaction operates on the data item, first apply for the lock c...

Abstract

The invention belongs to the technical field of data information security processing, in particular to a field data information security control method of a distributed centralized control system, theinvention also provides a field data information security control system applied to a distributed centralized control system, If a transaction operates on a data item, the lock control permission ofthe corresponding data item is first applied for, If within the corresponding locking period, Request for locking permission for the appropriate data item succeeded, the corresponding data item is locked, As there is no clear boundary between that network and the distribute system in the prior art, the invention solves the problem that the integrity and consistency of the database are destroyed, and the correct result cannot be obtained by the parallel operation of a plurality of transaction, and has the effects of good integrity and consistency, high reliability, avoidance of deadlock and safety of data items.

Description

technical field [0001] The invention belongs to the technical field of data information security processing, and in particular relates to a field data information security control method of a distributed centralized control system. The invention also provides a field data information security control system applied to a distributed centralized control system. Background technique [0002] A distributed processing system is a tightly coupled system, and a distributed processing system generally has a relatively complex interconnection network. The difference between it and a network is that although a computer network has similarities with a distributed computer system, the two are not equivalent. . The biggest feature of a distributed system is that all computers and system resources in the entire system are transparent to users, that is to say, users can run programs by typing commands, and the operating system selects the most suitable computer for users to run other prog...
