Embodiment Construction

[0018] The principles and embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0019] figure 1 A schematic diagram of the structure of the data storage system is given, and a schematic diagram of the connection of multiple storage modules through the bus. On the communication bus that needs to use the data storage module, select multiple storage modules with appropriate capacity to connect to the bus. Between these storage modules They can use the bus to communicate with each other, and can also use communication methods other than the bus to communicate with each other, such as using wireless technology to communicate with each other. Other modules used to generate data are also connected to the bus at the same time.

[0020] Such as figure 2 , image 3 As shown, each storage module monitors whether there is data on the bus that needs to be stored. If not, it continues to monitor. If other modules generate...

Abstract

The invention discloses a data storage method and system, and the method comprises the steps: enabling a current preferential storage module in a plurality of storage modules to start to store data when the data needs to be stored, and enabling the current preferential storage module to communicate with other storage modules to inform the storage modules that the current preferential storage module are in a storage state; Judging whether the data is completely stored or not, if yes, ending the process, and if not, continuing the next step; Judging whether the capacity of the current priority storage module is used up or not, if not, continuing to store, and if yes, continuing to carry out the next step; Informing other storage modules, and taking the next priority storage module in the other storage modules as the current priority storage module to start to store the data. According to the invention, a plurality of storage modules can be automatically online and continuously stored.

Description

technical field [0001] The invention relates to a data storage method and a data storage system for storing data by using the data storage method. Background technique [0002] With the development of industrial automation, the demand for industrial field data storage is gradually increasing, and the demand for storage capacity is also increasing. If a large-capacity storage module is used, although the storage capacity demand can be solved, the cost is very expensive. Multiple relatively small-capacity storage modules are used instead. Although the cost is reduced, when multiple storage modules exist at the same time, only one module is actually used at the same time, and other modules are waiting to be used. The bus or the control center When reading and writing data, it is necessary to pay attention to the current usage of each data storage module, which will cause the bandwidth or resources of the bus or control center to be occupied. Contents of the invention [0003...
