1. terminal device network registration manages the configuration of the terminal device operation logic of monitoring collection 3. of 2. terminal device service datas
With the control of run action.
It is described in detail below for these three functions：
1. terminal device network registration management
Device power initialization is divided to two pieces：
First piece of terminal device power-up initializing finally enters login network access pattern；
Second piece of bridge module device power initialization, all basic functions required for initialization, such as communication channel, connection
Database, parsing terminal equipment configuration file form terminal equipment type masterplate etc., finally run terminal device scheduling feature,
30 milliseconds of timeslices of starting are used to send equipment probe messages in each 1 second period, when certain just upper electricity be in register into
The terminal device of net pattern receives this equipment probe messages, the device descriptor variable of this equipment is replied into bridge module, so
Receive the facility registration response message of bridge module reply afterwards etc., if terminal device receives facility registration response message, by oneself
It is designated registered networking pattern.Equipment probe messages are received again below not process；If terminal device does not receive equipment note
Volume response message, terminal device continues to be in login network access pattern, waits processing equipment probe messages again；
It is terminal device distribution communication and terminal device scheduler module receives the device descriptor variable of terminal device reply
Physical address, the communication physical address distributed to terminal device reply etc. are to be answered, if not receiving response, maximum is supported continuous
Send out again three times, if not receiving the physical address deletion that response is just distributed also more than 3 times, leap at next timeslice
Reason；If processing normal above, the physical address of distribution is issued into control data corporation with device descriptor variable encapsulation into message
Module, control data corporation module parses this message, and device type information in device descriptor variable replicates portion
The device type masterplate set up during initialization, for setting up this terminal device full impression in bridge module equipment, is based on
The communication physical address of distribution is managed the impression information of this equipment as hash key with hash tables, and will be distributed physically
Location and device descriptor information are stored in database as a record（So that electricity is gone up after device powers down again, can to it is registered enter
The equipment of net is recovered automatically）, a message then is replied to terminal device scheduler module, end equipment scheduler module disappears this
Breath is packaged into facility registration response message, then waits the confirmation message that receiving terminal apparatus are replied, and end equipment scheduler module is received
Control data corporation module is issued to the confirmation message encapsulation messages replied, then passes through Upper machine communication module, finally encapsulated
Host computer is issued into udp messages.So far the network registration success of this equipment is confirmed.
2. the monitoring collection of terminal device service data
This function is built upon in terminal device network registration module basis, only when certain terminal device network registration into
After work(, the data of monitoring will be needed to be managed by hash tables in this terminal device, and according to the different attribute of data（Such as：
It is read-only, read-write, only write）It is separately added into different hash tables to be managed, sets up following all registered networking terminal devices
Full impression.All variables of all registration equipment are sent to by terminal device scheduler module by message, are adjusted in terminal device
The chained list pond of all variables is established in degree module, the scheduler task in terminal device scheduler module is by from chained list pond above
What is circulated successively takes a variable node, is sent to corresponding terminal device, waits the response of terminal device, if terminal device,
There is no response in certain time-out time, this variable is resend once, be at most repeated 3 times, if should again without receiving
Answer, confirm this equipment fault, notify host computer；The reply data that will be received, control data corporation module is sent to by message,
After being parsed, the real time information of each variable impression set up in hash tables is updated；Then the original after host computer is by disassembling
Sub- variable 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, the handling process being based on are the same, but due to the slightly a little difference of both characteristics, so entering
Differentiation treatment is gone.Configuration data is not very high due to frequent operation and requirement of real-time, and control data operation is frequent
It is all relatively high with requirement of real-time, so being put into both data based on being processed in priority query, will control
The priority of data sets the priority higher than configuration data, make control data be come before the queue of configuration data,
Control data is allowed preferentially to be processed；Control data corporation module carries out parsing merging successively to control and configuration data in queue
The logical variable that forming apparatus are supported, the notice message for waiting host computer transaction operation of transmission to finish, will parse patrolling for merging
Collect variable encapsulation and be sent to terminal device scheduler module into message, transmit queue, terminal are set up in terminal device scheduler module
In the configuration and control time piece for issuing in equipment scheduling module, by the control in this queue and configuration data, data are packaged into
Frame, is sent to terminal device；Host computer is read out to confirm whole configuration to the execution state of configuration data or control operation
Or whether control operation runs succeeded.
The problem that the present invention exists for prior art：In a first aspect, using the full modularization consistent terminal section of each function
Point, will all I/O nodes individually into I/O module, temperature controller, Men Xian, plug-in card power taking, all function opposite independents such as curtain control
Module is formed, it is unified to be communicated with bridge module by RS485 buses, which solves according to different demands（Such as 1. IO
Points are relatively more, and multiple I/O modules are hung in just selection, 2. have multiple temperature controllers, you can to connect multiple temperature controllers, if without temperature control
Device, it is also possible to do not connect）, carry out flexible combination.
Second aspect, is packed by the carrying out to information in each terminal module and the atom of information splits, information package
For reducing the message number communicated in bus between each terminal module and bridge module, it is to avoid because communication count off is relatively more,
Cause bus busier, so as to influence the performance of communication.The atom of information splits and is used for carrying out the information of packing in logic
Atom split, i.e., one variable represents a meaning, enters the decoupling of row information, and benefit is that one side is solved due to variable
On the other hand binding, the complexity for causing host computer to process shields the internal structure of upper understanding lower terminal module.Further
The upper decoupling with terminal module of individual aspect, i.e. the change of terminal module does not interfere with host computer, is also conversely such.
The third aspect, the equipment for needing addition system is parsed by describing the configuration file of terminal module configuration attribute
Information, and each variable combination and split mode, when there is new terminal module to need addition system, bridge module need not be changed
The description information of new terminal module is jumped in software, it is only necessary to superincumbent configuration file, addition one, you can complete this new terminal module
Information processing.
