2. the monitoring collection of terminal device service data
This function is to be based upon in terminal device network registration module basis, only have when after certain terminal device network registration success, being about to needs the data of monitoring to show to manage by hash in this terminal device, and add respectively different hash tables to manage according to the different attribute of data (as: read-only, read-write, only write etc.), set up the full impression of all registered networking terminal devices below.By message, all variablees of all device registrations are sent to end equipment scheduling module, in terminal device scheduler module, set up the chained list pond of all variablees, scheduler task in terminal device scheduler module is by the variable node of getting circulating successively from chained list pond above, send to corresponding terminal device, wait for replying of terminal device, if terminal device, in certain time-out time, do not reply, this variable is resend once, repeat 3 times at most, if still do not receive and reply, confirm this equipment failure, notice host computer; By the reply data of receiving, by message, send to control data corporation module, after resolving, upgrade the real-time information of each variable impression of setting up in hash table; Then host computer, by the atom variable after disassembling, reads this real-time information, reaches the monitoring collection to terminal device service data.
3. the configuration of terminal device operation logic and the control of run action
Configuration and control data, based on treatment scheme the same, but due to both slightly a little difference of characteristic, so carried out differentiating and processing.Configuration data is because frequent operation and requirement of real-time are not very high, and the frequent and requirement of real-time of controlling data manipulation is all relatively high, so by these two kinds of data, be put into based on processing in priority query, to control the priority setting of data higher than the priority of configuration data, make to control data and be all the time before the queue that comes configuration data, allow and control high priority data and processed; Control data corporation module resolves to control and configuration data in queue the logical variable that the equipment that is merged into is supported successively, wait for that host computer sends a complete notice message of transaction operation, the logical variable of resolving merging is packaged into message and sends to end equipment scheduling module, in end equipment scheduling module, set up transmit queue, hold in equipment scheduling module at the configuration issuing and control time sheet, by the control in this queue and configuration data, be packaged into Frame, send to terminal device; Host computer reads the executing state of configuration data or control operation, confirms whether whole configuration or control operation run succeeded.
The present invention is directed to the problem that prior art exists: first aspect, adopt the consistent terminal node of each function of full modularization, be about to all IO nodes and become separately IO module, temperature controller, door is aobvious, plug-in card power taking, the relatively independent formation modules of all functions such as curtain control, unified by RS485 bus and bridge module communication, this has just solved according to different demands, and (for example 1. IO count often, just select to hang multiple IO modules, 2. there are multiple temperature controllers, can connect multiple temperature controllers, if there is no temperature controller, also can not connect), carry out flexible combination.
Second aspect, by the carrying out packing to information in each terminal module and the atom of information, split, information package is used for reducing between each terminal module and bridge module the message number of communication in bus, avoid because communication count off is many, cause bus busier, thereby affect the performance of communication.The atom of information splits the atom that is used for the information of packing to carry out in logic and splits, a variable represents a meaning, the decoupling zero of the information of carrying out, benefit is to have solved on the one hand the binding due to variable, cause the complicacy of host computer processing, shielded on the other hand the inner structure of upper understanding lower terminal module.The upper decoupling zero with terminal module in another aspect, i.e. the variation of terminal module can not have influence on host computer, is like this on the contrary yet.
The third aspect, by describing the configuration file of terminal module configuration attribute, resolve the facility information that need to add system, and the combination of each variable and fractionation mode, when there being new terminal module need to add system, bridge module does not need to revise software, only needs superincumbent configuration file, the descriptor of adding a jumping new terminal module, can complete the information processing of this new terminal module.
