Description of drawings
Fig. 1 is the structural drawing that the utility model is striden the process automation system of hardware platform.
Fig. 2 list client is carried out the configuration synoptic diagram to many hardware platforms.
Fig. 3 multi-client carries out the configuration synoptic diagram to single hardware platform.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Total system structure of the present utility model has been described as shown in Figure 1.
Native system adopts traditional C/S framework pattern, and client adopts named pipes to realize data and communicating by letter that message is instructed with server.Client mainly is the presentation layer of system, and the user disposes accordingly in client, can be connected to corresponding server.Client provides the configuration interface of the man-machine interaction of process automation software development system, with the graphical displaying that receives user's operating command and show various data.
Server has comprised business logic processing layer, lasting data layer and the data source layer of system, is mainly used in responding the various data that man-machine interaction sends and handles and business operating instructions.The data source layer is the data file that each automation system platform is fixed self.
The lasting data layer is made up of isomeric data access interface and two parts of memory database.The isomeric data access interface with the data in the various heterogeneous databases, adopts the uniform data model method for expressing, is mapped in the memory database.Work as Business Logic, only need according to the data representation model that pre-defines, memory database is operated accordingly, namely realized the corresponding renewal of former heterogeneous database.Therefore, when new heterogeneous data source adds, only need the access interface in integrated new data source, Business Logic need not change, just can realize the integrated operation in new data source.
Business Logic is made up of business logic processing module and interprocess communication interface.The interprocess communication interface, based on the named pipes server of a multithreading, the ducted data of real-time listening receiving operation and the request instruction that each client sends, and send this operation requests message the message queue of business logic processing module.The business logic processing module, the first in first out mechanism of employing message queue is obtained corresponding data, and is carried out corresponding business logical operation, and operating result is sent to corresponding client by the interprocess communication interface from internal storage data.Under the multiple-person cooperative work pattern, this message queue pattern has effectively been avoided the concurrent operations of database, thereby has improved the reliability of system.
Because the SDK (Software Development Kit) of each manufacturer, at employings such as data variable, network structure, IO equipment, SCADA interface separately different file layout define, native system is set up the uniform data model method for expressing at memory database above-mentioned object is described, eliminate difference, thereby improved the extendability and opening of system greatly.The SDK (Software Development Kit) of each manufacturer, the database difference that adopts, the data representation method of object model also is not quite similar, thereby the integrated access interface of the heterogeneous database of native system, be mainly used in the multi-data source of variant form is converted into the forms data source with master pattern form the compatibility of the hardware platform of realization and each automated system.
Single client has been described as shown in Figure 2 to the configuration structure figure of many hardware platforms.Various configuration configuration interface processes have been moved on the client, each process is all as the client of a named pipes, the user can specify the address of arbitrary named pipes server in advance before starting configuration interface, thereby connects all automation system platforms under the current network.The user can revise corresponding configuration data by patterned mode in configuration interface, interactive interface also can effectively be showed the data model in the memory database in patterned mode according to user's demand.The connection request of client is monitored in the server circulation, and is each connection of client, creates a message and monitors and processing threads, response user's various operations.When the user need connect other hardware platform, only need to disconnect current connection, reassign the address of other hardware platform corresponding server, just can in identical configuration interface, adopt identical collocation method that other hardware platform is operated.
The configuration structure of multi-client to single hardware platform described as shown in Figure 3.The named pipes server is opened up a thread is monitored client with circulation each connection request separately.At each connection, host process is opened up an independently watcher thread again, to respond the various instructions that corresponding client sends.Namely when two clients all asked to connect same hardware platform corresponding server, server was created two independent threads at these two clients, was responsible for monitoring the information order of handling these two clients.Thereby the user of customer end A can carry out the configuration of data variable to hardware platform, and customer end B can be carried out the configuration of steering logic to same hardware platform.Two clients are operated the object database of bottom simultaneously, are independent of each other.Operate with one piece of data simultaneously for fear of a plurality of threads simultaneously and cause data corruption, server is introduced the mutual exclusion mechanism of Mutex, guarantees the exclusive reference (being to have only a thread accesses the same time at most) of data resource.
More than show and described ultimate principle of the present utility model, principal character and advantage.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the instructions just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
