Description
Technical Field
The present invention relates to a data storage method, and a data storage system for storing data using the data storage method.
Background
With the development of industrial automation, the demand of industrial field data storage gradually increases, and the demand for storage capacity also increases day by day, if a large-capacity storage module is adopted, although the demand for storage capacity can be solved, the cost is very expensive, if a plurality of relatively small-capacity storage modules are adopted for replacement, although the cost is reduced, when a plurality of storage modules exist simultaneously, only one module actually used at the same time is still needed, other modules are all in a standby state, and a bus or a control center needs to pay attention to the use condition of each current data storage module when reading and writing data, so that the bandwidth or resource of the bus or the control center is occupied.
Disclosure of Invention
In order to solve the technical problems that in the prior art, the cost of a single large-capacity storage module is high, and the management of a plurality of small-capacity storage modules consumes common resources, the invention provides a data storage method, which comprises the following steps:
when data needs to be stored, the current priority storage module in the plurality of storage modules starts to store the data and communicates with other storage modules to inform that the storage modules are in a storage state;
judging whether the data is stored completely, if so, ending the process, and if not, continuing the next step;
judging whether the capacity of the current priority storage module is used up, if not, continuing to store, and if so, continuing to the next step;
and informing other storage modules, wherein the next priority storage module in the other storage modules is used as the current priority storage module to start to store data.
Preferably, after receiving the notification of the stored state of the current priority storage module, the other storage modules enter the sleep state, and only retain the communication function.
Preferably, before determining whether the capacity is used up, determining whether a capacity value of the current priority storage module is smaller than or equal to a preset dangerous value, if so, notifying other storage modules by the current priority storage module, so that a next priority storage module in the other storage modules exits from a sleep state, enters a ready state, and waits for the current priority storage module to notify that the capacity is used up.
In a specific embodiment, the danger value is calculated in real time according to the current storage speed and the residual capacity before storage, or the danger value is a fixed value. The storage modules are connected through a bus. The memory modules can communicate with each other through a bus. The current priority storage module is a storage module with the capacity not used up and the address value being the minimum. The address values of the memory modules may be obtained from an address table created by each memory module during an initialization phase.
The invention also protects a data storage system for storing data by adopting the data storage method.
In one embodiment, the storage module comprises a storage unit for storing data, a communication unit for communicating with other storage modules, a storage management unit for calculating and managing the capacity of the storage module, and a power management unit for controlling the storage module to enter a standby state or a sleep state according to the data received by the communication unit.
According to the invention, the other memory modules on the bus are mutually communicated through the mutual communication of the memory modules, so that the other memory modules know the mutual dynamic state, CAN be automatically used online according to the use condition, and continuously store all data on the same bus, and the communication technology among the memory modules includes but is not limited to CAN, RS485, wireless and the like, so that the states of the other memory modules are obtained, the memory management is simplified, and the energy consumption of equipment is reduced.
Drawings
The invention is described in detail below with reference to examples and figures, in which:
FIG. 1 is a system connection diagram according to an embodiment of the present invention.
Fig. 2 is a block diagram of a memory module according to an embodiment of the present invention.
FIG. 3 is a flow chart of a method according to an embodiment of the present invention.
Detailed Description
The principles and embodiments of the present invention are described in detail below with reference to the accompanying drawings.
Fig. 1 is a schematic structural diagram of a data storage system, in which a plurality of storage modules are connected via a bus, and a plurality of storage modules with appropriate capacity are selected to be connected to the bus on a communication bus that needs to use the data storage modules, and the storage modules may communicate with each other by using the bus, or may communicate with each other by using a communication method other than the bus, for example, by using a wireless technology. Other modules for generating data are also connected to the bus.
As shown in fig. 2 and 3, each storage module monitors whether data needs to be stored on the bus, if not, the monitoring is continued, if data needs to be stored in other modules, the current priority data storage module stores the data in its own storage unit, and simultaneously, the communication unit sends a data frame to inform other storage modules that the other storage modules are in the stored state.
At the moment, the current priority storage module continuously stores data, whether the data are stored completely is judged in the storage process, if yes, the process is ended, if not, when the capacity value of the current priority storage module reaches a dangerous value, a data frame is sent to the outside through a communication unit, other storage modules are informed that the current priority storage module is fast full of the data frame, at the moment, the next priority storage module in other storage modules receiving the data frame exits from a dormant state, enters a ready state, waits for the current priority storage module to inform that the capacity of the current priority storage module is used up, and is ready to be stored. In this embodiment, the risk value is calculated in real time by the storage speed and the remaining capacity at the beginning of storage, and may be a fixed value, for example, 20%. The priority storage module can be a storage module which is not full and has the smallest address value, an address table can be created in the initialization stage during communication between the storage modules, data are firstly stored according to the storage module with the smallest address value in the address table, and then the data are sequentially moved downwards.
When the capacity of the current priority storage module is used up, the communication unit sends the data frame again to inform other storage modules that the capacity of the current priority storage module is used up, and the next priority storage module which is quitted from the dormant state quickly responds to the next priority storage module, sets the current priority storage module to start storage work, and stores subsequent data into the current priority storage module. And so on until the data storage is finished.
By the method and the system, the invention can realize the functions of matching a plurality of storage modules and automatically performing online work. And finally, data storage management is optimized, and the energy consumption of equipment is saved.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
