Embodiment one
The present embodiment provides a kind of interaction storage method of data, be applied to including multiple controllers and with multiple controllers
The communication network of the server-side of communication connection；The interaction storage method of the data includes：
After controller starting, judge whether that the network for receiving the communication network derived from the server-side is set
It sets；If so, searching the controller being associated, and establish with the controller being associated according to the network settings
Communication connection, to interact storing data between the associated controller；If it is not, then continuing next step；
Sequential search controller adjacent thereto is established with adjacent controller and is communicated to connect, with the adjacent control
Interaction storing data between device processed.
The interaction storage method of data provided by the present embodiment is described in detail below with reference to diagram.This implementation
The interaction storage method of the example data is applied to communication network 1 as shown in Figure 1, and the communication network 1 includes multiple controllers
11 and with multiple controllers 11 communication connection server-side 12.
Fig. 2A is please referred to, flow diagram of the interaction storage method of data in an embodiment is shown as.Such as Fig. 2A institute
Show, the interaction storage method of the data specifically includes following steps：
S21 judges whether the net for receiving the communication network derived from the server-side after controller starting
Network setting；If so, executing S22；If it is not, then executing S23.In the present embodiment, the network settings of the communication network include
The IP address of the quantity of controller, the network topology of the communication network and/or each controller in the communication network.
S22, according to the network settings, searches the control being associated if receiving the network settings of the communication network
Device processed.
S24 is established with the controller being associated and is communicated to connect, deposited with interacting between the associated controller
Store up data.
For example, directly searching for several plc controllers down since the machine ip on a local area network and being attached, reach
Certain amount just stops, and such plc controller can intersect access, and every plc controller can obtain other several plc
Data, work normally when, by the setting on tablet computer or server, finger is exchanged with each other between plc controller
Fixed storing data constitutes multiple data backup, primary to upload in the machine when server or platform are to read data
Caching all data, if server or plate obtain the data of other corresponding plc controllers, there is no need to again from
Other plc controllers read corresponding data up.
S23, if not receiving the network settings of the communication network, sequential search controller adjacent thereto.
For example, be connected with 3 plc controllers under a tablet computer or a server, respectively controller A, controller B and
Controller C, tablet computer do not do any network settings, three plc controller sequential scan IP adjacent controller.
S25 is established with adjacent controller and is communicated to connect, to interact storing data between the adjacent controller.
Specifically, according to the IP address of itself, the sequential search controller adjacent with the IP address of itself, and with itself
The adjacent controller of IP address establishes communication connection.
For example, controller A is connect with controller C, controller B is connect with controller A.Controller A store simultaneously the machine and
The data of controller C, controller B store the data of the machine and controller A simultaneously, and controller C stores the machine and controller B simultaneously
Data, obtain the data of A and C when scanning when plate access controller A simultaneously, then access B obtain B and A data because
This time data of paragraph controller C have obtained, then do not need obtaining data from C, the relationship and quantity mutually saved
There can be plate to be configured to artificially interfere the topology status of backup.
S26, it is waiting to receive after the access request of the server-side, it feeds back the data of itself storage and interacts and deposit
The data of the controller of data are stored up to the server-side.
The present embodiment also provides a kind of acquisition methods of data, is applied to lead to including multiple controllers and with multiple controllers
Believe the communication network of the server-side of connection；The acquisition of the data includes：
After entering predetermined sweep time section, according to the network settings of communication network and the demand for obtaining data to multiple controls
Device processed sends access request, to carry out sequential access to controller, and obtains the data being intended on access controller and interacts
The data of the controller of storing data；
Continue the data on the controller that access is not interacted with desire access controller in the previous step, and obtains the control
Data on device.

Fig. 2 B is please referred to, the acquisition methods of the data flow diagram in an embodiment is shown as.As shown in Figure 2 B, described
The acquisition methods of data specifically include following steps：
S21 ', after entering predetermined sweep time section, according to the demand pair of the network settings of communication network and acquisition data
Multiple controllers send access requests, to carry out sequential access to controller, with obtain the data being intended on access controller and with
The data of its controller for interacting storing data.
In the present embodiment, after the desire access controller receives the access request, the data of itself storage are fed back
And interact storing data controller data to the server-side.
For example, when tablet computer access controller A, while obtaining controller A and interacting the control of storing data with controller A
The data of device C processed, then access controller B obtains controller B and interacts the data of the controller A of storing data with controller B,
Because the data of this time paragraph controller C have obtained, then do not need obtaining data from C, the relationship mutually saved and
Quantity can have plate to be configured to artificially interfere the topology status of backup.
S22 ' continues to access the data on the controller not interacted with desire access controller in S21 ', and obtains the control
The data stored on device processed.
For example, controller D does not interact storing data with controller A and controller B, continue access controller D, to obtain control
The data stored on device D processed.
The interaction storage method of data provided in this embodiment and the acquisition methods of data can reduce depositing for industrial plate
Storage and the requirement of database manipulation, tablet computer or server, which simply connect controller, can be arranged acquisition and display currently
Data and historical data, multiple duplication also can effectively restore the data before being out of order in the case where controller failure all the way,
In the case where the memory space on the increasing controller of present network bandwidth is increasing, network can be preferably utilized
Handling capacity and memory space save realizing the database of plate and the function of redundancy, while can also support multiple plates simultaneously
Show data.
