Embodiment
In order to deepen the understanding of the present invention, below in conjunction with embodiment and accompanying drawing, the invention will be further described, and this embodiment only, for explaining the present invention, does not form limiting the scope of the present invention.
Pollutant sources on-line monitoring architecture based on B/S framework as shown in Figure 1.In order to realize bidirectional real-time between monitoring service device and Web browser, adopted Flash XML Socket communication mode.The web access mechanism of standard adopts http protocol, only allow browser end initiatively to initiate request, and server is passive response, do not allow server to send a connection request to browser, that is to say not for server provides design to realize to browser propelling data.In contrast, XMLSocket solution keeps being connected with the open of server, the message that this connection allows the instant transmission of server to import into, and send request without client, guaranteed real-time.As the Flash Server in Fig. 2 is responsible for realizing server end and browser end XMLSocket establishment of connection, after successful connection, can realize by BC Server the bidirectional real-time of server end and browser end.
The control request that Web browser end is submitted to from interface according to user, as information such as target device, command type, pollutant numberings, by adding the information such as check code, bag length, according to our self-defining host-host protocol, be packaged into packet, control command is sent to server end from browser end.
According to the difference of the task of monitoring, server end is comprised of a plurality of monitoring service devices, as shown in Figure 2.Wherein BC Server is responsible for receiving the control request of sending from browser end and sends and control result to browser, receive and control after packet, packet is carried out to legitimacy parsing according to self-defined host-host protocol, as resolve correctly, further the type of analysis and Control order.Although adopting transmission standard of instrument etc., current national logarithm carried out standard, also support Long-distance Control, Dan Ge producer also there are differences when specific implementation, can not support all control types completely, so the demand of using according to reality, in our Framework design, some number adopts that instrument do not support, we can directly directly carry out Long-distance Control by data transmission unit DTU, make our pollutant sources on-line control system have flexibility highly.
By the analysis to control command type, we can select is to adopt instrument to number, or sends control command to DTU.If adopting instrument to number sends, data are resolved and extracted to server by the control packet receiving, encapsulate data into again the control command form that meets GB HJ/T212-2005, by server end DAQ Server as shown in Figure 2, data are mail to corresponding number and adopt instrument.If sent to DTU, the protocol type of supporting according to field apparatus, such as Panasonic's agreement, encapsulates data into the control command of Panasonic's protocol format, by DTU Server, data is mail to corresponding DTU.Number is adopted between instrument or DTU and field monitoring equipment by serial communication, and control command is sent to field monitoring equipment, as drive valve, pass valve, exceeding standard keeps sample, obtains instantaneous value, obtains detecting instrument state information etc.Field monitoring equipment fill order, adopts instrument by the result of feedback by number or DTU returns to monitoring service device, by BC Server, by XML Socket, feedback result is transferred to Web browser end.
As shown in Figure 2, on monitoring service device except be responsible for monitoring four kinds of terminals of different task, also has different ponds, comprise for recording the connection pool ConnectionPool of link information, in execution for the treatment of control information, control pond ControllingPool and control and wait for pond ControlWaitingPool, and for storing the data pool of all kinds of reception data.The latest data of reception is directly stored in internal memory, and the operation such as avoided frequent inquiry to database, read, has improved the speed that the page loads data.
Because the feedback data of terminal equipment responsing control command cannot be distinguished with general data, also promoter that cannot Tracing Control order, in order to realize the real-time control of browser end to remote equipment, such as long-range sampling, long-range valve, the long-range pass valve etc. opened, we arrange, and a number of units is adopted instrument or a certain moment of DTU is only processed a remote control command.Fig. 3 has provided the technique of real-time control based on pond in environmental protection Internet of Things.When browser end sends after the request of control, server end first checks in execution, to control to have or not in the ControllingPool of pond and mails to this number and adopt the control command of instrument or DTU and carry out, if do not had, new control command is added to ControllingPool, otherwise the pond ControlWaitingPool to be controlled such as added.When a certain control command executes, number adopts instrument or DTU uploads onto the server execution result, on server, will return results into corresponding data pool, according to the control information of mailing to this number in ControllingPool and adopting instrument or DTU, execution result is returned to the browser of the request of sending, and this control information is deleted from ControllingPool, from ControlWaitingPool, obtain and mail to next control command that this number is adopted instrument or DTU simultaneously, if there is such order, it is transferred to ControllingPool and carry out from ControlWaitingPool, being about to corresponding control information mails to corresponding number according to the link information in ConnectionPool and adopts instrument or DTU, carry out next control command.
In order to realize the real-time control of browser end to field apparatus, we realize bidirectional real-time based on Flash XML Socket.The XML Socket that on server, Flash Server is responsible for setting up server end and browser end is connected, connect after foundation, on server, based on BC Server and browser end, carry out bidirectional real-time, the browsing of browser end general information, inquiry etc. are still based on http protocol.
Fig. 4 has provided on server BC Server for monitoring and the handling process of browser.The control request that browser end is sent is resolved, if the bag receiving is resolved correct, in conjunction with the link information between browser and server, and the link information between server and target device, the control data that the request of controlling are encapsulated as to specific format enter in execution to control pond ControllingPool, according to target device, be that number is adopted instrument or DTU, select DAQ Server or DTU Server control data to be sent to the target device of appointment.
Fig. 5 has provided concrete monitoring and handling process that on server, DAQ Server adopts instrument for number, and on server, DTU Server is similar with it for monitoring and the handling process of DTU.DAQ Server is responsible for monitoring number and adopts the data that instrument is uploaded, the information of adopting instrument equipment by number in uploading data, go again to control and in the ControllingPool of pond, search the corresponding control command that whether has this number to adopt instrument and carry out, if have, number is now adopted to the result that data that instrument uploads control as response and return to browser end, otherwise process as general uploading data.
