Description
Technical field
Present document relates to the multi-protocols in a kind of RS485 buses and the conversion method between TCP procotols, belong to scene
Bus control technology field.
Background technology
Fieldbus is the underlying communication network for the scene of manufacturing, it realizes the in-site measurement control of Microcomputer
Bidirectional linked list node digital communication between instrument or equipment, has the characteristics that real-time, stability are high.Since the world in 2000
The electrician committee（IEC）Announcement has passed through IEC61158 standard for Fieldbus, now existing ten multiple fieldbus standards.
Ethernet is the local area network generally used in commercial field, constitutes Internet's in conjunction with ICP/IP protocol
Basis becomes de facto standards in network application, this but also field bus control system by Ethernet with
National information net
The monitoring integration of the integration realization whole nation becomes trend of the times.
DL/T 645-1997《Multifunction electric meter communication protocol》It is the rate that China is unification and specification multifunctional electric energy meter
Physical connection and agreement when device and data terminal equipment carry out data exchange and the power industry formulated
Standard.
CJ/T 188-2004《Family metering instrumented data transmission technology condition》It is that China is formulated for family with measuring instrument
The instrumented datas transmission such as a professional standard, including water meter, gas meter, flow meter, calorimeter basic principle, interface shape
Formula and physics
The requirement of performance, data link, Data Identification and data safety and data expression format.
Modbus agreements initially developed by Modicon companies, and it is most popular general to have become the industrial circle whole world
One of industry-standard protocol.China promulgates national standard GB/T 19582-2008 within 2008《Work based on Modbus agreements
Industry automated network specification》, and implement in 2008-09-01.
DL/T 645-1997, CJ/T 188-2004 and GB/T 19582-2008 communication protocols generally use standard at present
RS485 communication interfaces are as its physical layer transmission mode, communication baud rate 1200BPS-115200BPS, Zhu Congban
Duplex mode.
According to《State Council is about the notice for printing and distributing the comprehensive programme of work of energy-saving and emission-reduction》, gradually set up national network
Government offices' office building and large public building energy consumption monitoring platform, to national key cities' important building energy consumption
（Electricity, water,
Combustion gas, heat）It is monitored in real time, this is just needed using energy consumption data acquisition device to energy consumption measure device into line number
According to acquisition,
Then collected energy consumption data is uploaded into data center by TCP networks（Or data relay station）, and measure
Device is universal
Using DL/T 645-1997, CJ/T 188-2004 and GB/T 19582-2008 communication protocols, meanwhile, energy consumption number
According to collector
The physical interface for meeting professional standard is used between metering device（RS485 interfaces）, it is total that this relates to RS485
Conversion between three of the above agreement on line and TCP procotols, so, the present invention proposes in a kind of RS485 buses
Conversion method between multi-protocols and TCP procotols.
Invention content
It is an object of the invention to propose the multi-protocols in a kind of RS485 buses and the conversion between TCP procotols
Method realizes that DL/T645-1997, CJ/T188-2004 and GB/T19582-2008 communication protocol and TCP networks are assisted
Conversion between view.This protocol conversion model mainly uses the main website model based on agreement.
To achieve the goals above, design of the invention is as follows：
Generate system configuration file
In fieldbus based main website-slave station communication system, a communication main station equipment is connected by fieldbus
There are multiple communication slave station equipments, in entire main website-slave station communication system, only communication main station equipment, which has, actively sends out
The ability of communication is played, communication slave station equipment receives the information of communication main station equipment and carries out information exchange with communication main station equipment.
And communication main station equipment will be realized and communicate the communication between slave station equipment, communication main station equipment needs to know communication slave station equipment
The information such as address, communication protocol therefore first have to carry out a system configuration to whole system by communication main station equipment, allow
Communication main station equipment knows the relevant information for the communication slave station equipment being connected in bus, convenient for communication main station equipment to being entirely
System is managed.
Structure communication slave station equipment information table
Since communication main station equipment is to be controlled to realize by processor software with the communication communicated between slave station equipment, communication
Master device will be communicated with slave station equipment is communicated, it is necessary first to which the configuration information that system is read by program is communicated
Then the relevant informations such as address, the communication protocol of slave station equipment could be initiated to communicate.
If communication main station equipment actively initiates the configuration that communication is required for reading system to communication slave station equipment every time
The efficiency of information, system will be very low, in order to improve the operational efficiency of system, can be built according to the system configuration information of reading
Vertical communication slave station equipment information table, which is an Array for structural body, each nodes records of array are one
The information of a communication slave station equipment, the information include communication slave station equipment number, communication slave station equipment address, communication slave station equipment
