Description
Technical field
The present invention relates to technical field of circuit design, in particular to a kind of data collection system realized IIC and turn CAN protocol
And method.
Background technique
Communication protocol (communications protocol) refers to the rule of communication that communication parties are arranged in advance, can be with
It is simply interpreted as carrying out common language used in mutual session between each computer.Communication protocol has hierarchy, reliable
Property and validity.
As both entities complete communication or the be must comply with rule and agreement of service, communication protocol definition data sheet
The format that member uses, the information and meaning that information unit should include, connection type, the timing that information sends and receives, thus
Ensure that data are successfully transmitted to determining place in network.
In computer communication, communication protocol is for realizing the standard between computer and network connection, if network does not have
There is unified communication protocol, the information transmitting between computer can not just identify.Two computers are when being communicated, it is necessary to use
Communication protocol.
Common communication protocol mainly includes tri- kinds of agreements of TCP/IP, NETBEUI and IPX/SPX, every kind of association in local area network
Discuss the application environment for having its applicable.
In the industrial production, it is often necessary to certain parameters of equipment are obtained, thus the working condition of analytical equipment,
And result is shown.But often the acquisition of data and the display of analysis result need different communication protocol, complete not

The Diversification Problem of view, more and more prominent, performance, duration, cost and the system for having seriously affected automated system are stablized, solution
Certainly the conversion of automated system communication protocol and the problem of communication standardization, are significant.
It is more in IIC (Inter-Integrated Circuit, IC bus are a kind of multidirectional control buss)
A chip may be coupled under same bus structure, while each chip all can serve as to implement the voltage input of data transmission, this
Kind mode simplifies signal transmission bus.Iic bus is minimum using signal wire in various buses, and has automatic addressing, more
The bus of the functions such as host clock synchronization and arbitration.Therefore, using iic bus design a calculating machine system it is very convenient flexibly, body
Product is also small, thus is used widely in all kinds of practical applications.
And CAN (Controller Area Network, controller LAN) belongs to the scope of fieldbus, is a kind of
Effectively support the serial communication network of dcs.It is got over due to its high-performance, high reliability and unique design
It is more valued by people, is widely used in numerous areas.And it is capable of detecting when any mistake generated.When signal passes
When defeated distance reaches 10km, CAN bus stills provide the up to message transmission rate of 50kbit/s.Since CAN bus has very
High real-time performance and application range reaches as high as the high speed network of 1Mbps to the 50Kbps of inexpensive multi-line from bit rate
Network can arbitrarily arrange in pairs or groups.Therefore, CAN is own is obtained in the fields such as car industry, aircraft industry, Industry Control, security protection
It is widely applied.
