Make CAN Beyond Automotive into Industrial
自从第一控制器局域网（CAN）出现在1987，曾经是一个汽车网络接口现在已经扩展到工业应用。随着越来越大的足迹来了收发器的需求，总线长度更长，更多的总线节点，更高的数据吞吐量和更大的电压隔离。
现在有超过20家半导体公司提供设备，设计人员有许多决定，并需要充分了解规范的细微差别和最新的迭代，然后选择最佳的设备。为此，我们将探讨规范和主题，如不对称，然后让你加快速度在一些有趣的CAN设备，以及如何充分利用它们。
Why CAN？
The controller area network （CAN bus） was first developed in the early 1980s at Robert Bosch GmbH. The first CAN controller chips were introduced in the market in 1987 and the first vehicle to implement the CAN bus was on the road in 1988. In the almost 30 years since， usage of the CAN bus has become ubiquitous in vehicles all over the world and in various forms of transportation， including busses， trains， planes and ships.
It is also widely used in many industrial settings such as plant automation， agriculture and heavy equipment， medical devices， elevators， and lift control. It is highly suitable for many embedded control applications as a low cost， low protocol overhead， deterministic network that features error detection and retransmission.
More than 20 semiconductor companies offer devices that support the CAN bus and there are many tool vendors and commercial and open source versions of software available – from drivers up through middleware and higher level protocol stacks.
Let’s take a look at some of the characteristics of the CAN bus that makes it useful in so many settings.
