CANTCP-02功能简介1.1 CAN总线概述CAN 是Controller Area Network的缩写（以下称为CAN），是ISO国际标准化的串行通信协议。
在当前的汽车产业中，出于对安全性、舒适性、方便性、低公害、低成本的要求，各种各样的电子控制系统被开发了出来。
由于这些系统之间通信所用的数据类型及可靠性的要求不尽相同，由多条总线构成的情况很多，线束的数量也随之增加。
为适应“减少线束的数量”、“通过多个LAN，进行大量数据的高速通信”的需要，1986 年德国电气商博世公司开发出面向汽车的CAN 通信协议。
此后，CAN 通过ISO11898 及ISO11519 进行了标准化，现在在欧洲已是汽车网络的标准协议。
现在，CAN 的高性能和可靠性已被认同，并被广泛地应用于工业自动化、船舶、医疗设备、工业设备等方面。
1.2 CANTCP-02简介CANTCP-02是广州恩浦电子有限公司开发的一款工业级以太网CAN-bus数据转换设备，符合CAN2.0A和2.0B规范，针对工业应用和煤矿等领域设计，满足工业自动化系统对设备严格的性能要求。
它内部集成了一路/两路CAN-bus接口和一路EtherNet接口以及TCP/IP协议栈，用户利用它可以轻松完成CAN-bus网络和EtherNet网络的互连互通，进一步拓展CAN-bus网络范围。

(20)S to ck C he ck .c omChapter 1 IntroductionThe JetBox 8152 has two ports for I/O communications, One RS-232/422/485 port and one CANBUS port. The CAN (Controller Area Network) is a serial bus system especially suited for networking "intelligent" I/O devices as well as sensors andactuators within a machine or plant. Characterized by its multi-master protocol,real-time capability, error correction, high noise immunity, and the existence of many different silicon components, the CAN serial bus system, originally developed byBosch for use in automobiles, is increasingly being used in industrial automation.CANbusThis section describes how to program and use the CANBUS. It provides a description of the I/O memory map of the chip and discussion of the internal registers to aid youin programming your CAN controller chip.Defined Memory Mapping and InterruptThe CANBUS occupies 2 bytes of memory space. You can set the base address andaccess to the internal resources of the SJA1000 CAN controller chip. The SJA1000 chip access is multiplexed in such a way that the host must first write to 300h the internal address of the CAN chip and after that perform a write to address 301h with the actual data to be written into the desired memory location. Address 302h is a hardware-reset function of the SJA1000. Performing a read or write to this addressS to ck C he ck .c omwill cause a hardware reset to the CAN controller. You may need to reset the chip in case of an unrecoverable error in the CAN controller chip. And your can use interrupt the main processor when a message is received or transmitted if interrupts areenabled on the JetBox 8152. By using interrupts you can write powerful code to CAN.Example ProgrammingWrite 300H to the CAN controller Control byte located in the on-chip address 0. The Example is listed below:Outportb (0x300, 0x00) : Write CAN Address 0 (Control Register ) Outportb (0x301, 0x78) : Write Data of CAN Address 0 (Control Register )And please see “SJA1000.pdf” for further information of the SJA1000 chip.Description Factory SettingBase Address 300HData Of Address301H Hardware Reset Of SJA1000 Chips302H Interrupt Require Quest11S to ck C he ck .c omChapter 2 Hardware Configuration2-1 Pin AssignmentThe CANBUS is use DB9 standard connector. The following tables show the CANBUS signal connections of this connector.Note 1: The CANBUS DB9-pin out conforms to the ISO 11898/2 standard2-2 Jumper Setting: JP6JP6: CANBUS Terminal Resistor SelectionNote 2: The JP6 is the CANbus termination jumper.

汽车CAN总线详细教程
2003年，大众集团在新PQ35平台上使用五重结构的Canbus系统，并且出现了单线的LIN-BUS。
CAN技术的发展
20世纪80年代，Bosch的工程人员开始研究用于汽车的串行总线系统，因为当时还没有一个网络协议能完全满足汽车工程的要求。参加研究的还有Mercedes-Benz公司、Intel公司，还有德国两所大学的教授。 1986年， Bosch在SAE（汽车工程人员协会）大会上提出了CAN 1987年，INTEL就推出了第一片CAN控制芯片—82526；随后Philips半导体推出了82C200。 1993年，CAN的国际标准ISO11898公布 从此CAN 协议被广泛的用于各类自动化控制领域。
但是轿车上基于CAN的控制网络至今仍是各大公司自成系统，没有一个统一标准。
基于CAN的应用层协议应用较通用的有两种：DeviceNet（适合于工厂底层自动化） 和 CANopen（适合于机械控制的嵌入式应用）。 任何组织或个人都可以从DeviceNet供货商协会（ODVA）获得DeviceNet规范。购买者将得到无限制的、真正免费的开发DeviceNet产品的授权。 DeviceNet自2002年被确立为中国国家标准以来，已在冶金、电力、水处理、乳品饮料、烟草、水泥、石化、矿山等各个行业得到成功应用，其低成本和高可靠性已经得到广泛认同。

该软件在模拟系统接口数据的同时，实现对各种不同类型数据的灵活设置，可模拟系统的各种输出数据。
经过测试，模拟软件运行稳定，响应及时，能够完成对系统基本接口及功能的模拟，方便开发人员进行数据通信，轻松完成场景搭建。
关键词：CAN口、串口、模拟软件1引言在某型设备进行通信测试过程中，需要通过具备多个CAN口、多个串口的系统与其进行数据交互。
该设备对实时性要求高，需要系统具备毫秒级响应能力；同时，该设备同时进行多个CAN口、多个串口的数据通信，要求系统具备并行处理能力。
目前在用的系统，存在价格昂贵、体积较大等缺点，从经济方面考虑，其性价比较低，从易用方面考虑，其体格笨重不便使用。
针对如此现实情况，结合设备测试的需求及系统的特点，采用软件模拟系统的相关功能，搭配CAN接口盒和串口扩展设备，实现对某型设备的通信测试，从而达到经济、易用的目的。
Qt是基于C++语言的图形用户界面开发框架，具有跨平台特性，且拥有面向对象开发、丰富的API及易用且开源的开发环境等特点。
同时，Qt提供了丰富的类，采用QSerialPort和QSerialPortInfo类，可方便地完成对串口的操作；采用Qthread类进行多任务处理，从而实现多个功能模块的同时运行。
USBCAN-II是高性能的工业级CAN接口卡，兼容USB2.0全速规范，带有2路CAN接口。
采用该接口卡，PC机可通过USB总线，方便地连接至CAN网络，构成CAN网络领域的数据采集及数据处理。
2模拟软件设计2.1模拟软件体系模拟软件主要包括设备管理和功能模拟两个部分。
设备管理主要完成对接口设备的设置、接口数据的拆包和组包以及接口数据的保存；功能模拟主要完成不同功能模块的设置、不同数据的设置及接口数据的解析和处理。
