In order to deepen the understanding of the present invention, below in conjunction with embodiment and attached drawing, the invention will be further described, should
Embodiment is only used for explaining the present invention, is not intended to limit the scope of the present invention..
Pollution sources on-line monitoring architecture based on B/S frameworks is as shown in Figure 1.Server and Web are monitored in order to realize
Bidirectional real-time between browser uses Flash XML Socket communication modes.The web access mechanism of standard uses
Http protocol only allows browser end actively to initiate request, and server is not allow server to be sent out to browser by dynamic response
Go out a connection request, that is to say, that do not provide design to browser propelling data for server and realize.In contrast,
XMLSocket solutions keep connecting with the open of server, this connection allows server to send incoming message immediately,
Request is sent out without client, ensure that real-time.As the Flash Server in Fig. 2 are responsible for realizing server end and browsing
Device end XMLSocket establishment of connections can realize pair of server end and browser end by BC Server after successful connection
To real-time Communication for Power.
The control data that Web browser end is submitted according to user from interface, such as target device, command type, pollutant
The information such as number are packaged into data packet by information such as addition check code, packet length according to our customized transport protocols, will
Control command is sent to server end from browser end.
According to the difference of the task of monitoring, server end is made of multiple monitoring servers, as shown in Figure 2.Wherein BC
Server is responsible for receiving the control data sent out from browser end and sends control result to browser, receives control data
Bao Hou carries out legitimacy parsing according to self-defined transport protocol to data packet, such as parses correctly, further analysis and Control order
Type.Although country's logarithm adopts transmission standard of instrument etc. and carried out specification at present, remote control is also supported, each producer is specific
There is also differences when realization, can not support all Control Coolings completely, so according to the demand of actual use, ours
In Framework design, some numbers adopt what instrument was not supported, we directly can directly be carried out by data transmission unit DTU remotely
Control so that our pollution sources on-line control system has the flexibility of height.
By the analysis to control command type, we can select to be to adopt instrument to number, or send control life to DTU
It enables.If adopting instrument to number to send, the control data bag received is parsed and extracts data by server, then encapsulates data into symbol

Instrument is adopted toward corresponding number.If sent to DTU, according to the protocol type that field device is supported, such as Panasonic's agreement, data are sealed
Data are sent to corresponding DTU by the control command for dressing up Panasonic's protocol format by DTU Server.It is several to adopt instrument or DTU and show
By serial communication between monitoring device, control command is sent to field monitoring equipment, such as valve opening, close valve, over-standard sample retention,
Obtain instantaneous value, obtain detection meter status information etc..Field monitoring equipment executes order, and the result of feedback is adopted instrument by number
Or DTU returns to monitoring server, and feedback result is transferred to Web browser end by XML Socket by BC Server.
As shown in Fig. 2, monitor on server other than being responsible for monitoring four kinds of terminals of different task, also different ponds,
Include the connection pool ConnectionPool for recording link information, for controlling pond in handling the execution of control information
ControllingPool and control wait for pond ControlWaitingPool, and the data for storing all kinds of reception data
Pond.The latest data of reception is stored directly in memory, the operations such as frequent inquiry, the reading to database is avoided, improves
The speed of page load data.
Since the feedback data of terminal device responsing control command can not be distinguished with general data, control can not be also tracked
The promoter for making order, in order to realize real-time control of the browser end to remote equipment, such as long-range sampling, long-range valve opening, far
Journey closes valve etc., we arrange, and a number of units adopts instrument or the DTU a certain moment only handles a remote control command.Fig. 3 gives environmental protection
Technique of real-time control based on pond in Internet of Things.After browser end sends out control data, server end first checks to be controlled in execution
Whether there is or not the control commands for being sent to the number and adopting instrument or DTU to be carrying out in pond ControllingPool processed, if it is not, by new
Control command ControllingPool is added, the pond ControlWaitingPool to be controlled such as be otherwise added into.When a certain
Control command has executed, and number adopts instrument or DTU uploads onto the server implementing result, will be returned the result into corresponding number on server
According to pond, instrument or the control information of DTU are adopted according to the number is sent in ControllingPool, implementing result is returned to send out and is asked
The browser asked, and the control information is deleted from ControllingPool, while being obtained from ControlWaitingPool
Take and be sent to the number and adopt instrument or the next control command of DTU, if there is such order, by its from
ControlWaitingPool is transferred to ControllingPool and executes, i.e., will control accordingly information according to
Link information in ConnectionPool is sent to corresponding number and adopts instrument or DTU, executes next control command.
In order to realize real-time control of the browser end to field device, it is two-way that we are based on Flash XML Socket realizations
Real-time Communication for Power.Flash Server are responsible for establishing server end on server connects with the XML Socket of browser end, connects
After foundation, bidirectional real-time is carried out based on BC Server and browser end on server, browser end general information it is clear
It lookes at, inquire etc. and being still based on http protocol.
Fig. 4 gives monitorings and process flow of the BC Server for browser on server.Browser end is sent out
Control data is parsed, if the Packet analyzing to reception is correct, in conjunction with the link information between browser and server, and
Link information between server and target device, the control data that control data is encapsulated as to specific format enter in execution to control
Pond ControllingPool is that number adopts instrument or DTU according to target device, selects DAQ Server or DTU Server that will control
Data processed are sent to specified target device.
Fig. 5, which gives DAQ Server on server and adopts the specific of instrument for number, to be monitored and process flow, DTU on server
Server is similar with process flow with its for the monitoring of DTU.DAQ Server are responsible for monitoring the data that number adopts instrument upload, pass through
It uploads number in data and adopts the information of instrument equipment, then go in control pond ControllingPool to search whether that the number adopts the phase of instrument
Control command is answered to carry out, number at this time, which is adopted the result that the data that instrument uploads control in response, if having returns to browser
Otherwise end is handled as the general data that upload.
