CSM 让CAN通信不再难
不懂CAN-bus协议,也能实现安全可靠的CAN-bus通信!选择CSM模块,省心!众所周知,CAN-bus由于其传输速率高、传输距离远且通信机制非常可靠等优点,使其在汽车、工业、医疗等领域得到广泛的应用。很多设备研发工程师纷纷将其作为设备首选的通讯方式,然而CAN协议的相对复杂性也让很多工程师望而生畏。好不容易写出了CAN协议栈,产品上市时间大大延后不说,通信还不一定可靠,直接导致产品的返修率高,售后技术支持的成本居高不下。况且如果CAN-bus不采用隔离技术,很容易受到地环路产生的共模电压以及来自外部的浪涌和群脉冲的干扰,导致CAN收发器、CAN控制器乃至整个设备的损坏。   广州致远电子精心研发的CSM100模块为您解决了上述所有难题。CSM100模块是集微处理器、CAN控制器、CAN收发器、DC/DC电源隔离、电气隔离于一身的嵌入式UART转CAN模块。用户只需操作UART,不需要知道有关CAN-bus的任何知识,就可以轻松地实现安全可靠的隔离CAN-bus通信。   当您一直在问自己:“我怎样才能将我的设备接入CAN-bus网络呢? 如何才能使整个CAN-bus网络安全可靠地通信呢?”等问题时,请选择CSM100模块。您只需将MCU的UART口和CSM100的UART口相连,将CSM100模块的CAN接口连接到CAN网络上就可以了,剩下的工作就只是在MCU上编写操作UART接口的代码。   总之,CSM100模块让您在不懂CAN的前提下,能轻而易举地实现安全可靠的CAN-bus通信,减少“阶段0”开发,加快产品的上市速度,抢占市场先机。

CTM让CAN通信更安全
CTM隔离CAN收发器,为您的CAN-bus通信保驾护航! CAN-bus由于其传输速率高、传输距离远且通信机制非常可靠等优点,使其在汽车、工业、医疗等领域得到广泛的应用。   相信大家对CAN-bus通信的传统方案并不陌生,那就是MCU连接CAN控制器,控制器连接CAN收发器,CAN收发器连接通信双绞线。这在电磁干扰不强的环境下表现得还算不错,例如在实验室环境中。但是当其应用于强电磁干扰的环境下,将会出现相当多的问题,从高误码率到收发器、控制器乃至整个系统的损坏,不一而足。这些问题是由于地环路产生的共模干扰,以及外部耦合进来的浪涌和群脉冲干扰所造成的。   为了让CAN-bus在强干扰环境下能可靠工作,工程师们采用隔离技术来解决上述问题。CAN控制器与收发器之间使用DC-DC(例如:ZY0505BS-1W)和光耦(例如:6N137)来实现电源和电气的完全隔离,并在收发器的输出端添加总线保护器件以避免地环路、浪涌和群脉冲产生的冲击。然而这势必增加器件的数量,占用更大PCB面积,使布局和布线变得复杂,且带来稳定性、可靠性和一致性的下降以及总线延迟的增加。   CTM模块完美地解决了上述所有问题,它集电源隔离、电气隔离、CAN收发器以及总线保护于一身,将干扰隔离在系统之外。其通信延时低至ns级;单一的模块减少了器件数量和所占用的PCB面积,布局布线简单明了;严格的EMC、防震、防潮、防腐蚀测试确保了模块的高的稳定性、可靠性和一致性。这是CTM模块的应用框图,您会发现使用CTM模块是如此的简单。

流体肌肉(2)Fluidic muscle
气动装置的“流体肌肉”是一个全新的气动驱动器,由Festo公司开发研制。它的仿生肌主要是一个中空的橡胶柱体,内置芳族聚酰胺纤维。如果流体肌肉中充满空气,它的直径扩大、长度减小,从而进行流动的弹性运动。“流体肌肉”的应用使得运动过程不仅在动作、速度和强度上与人体运动相似,而且在灵敏度上也与人体运动相似。“流体肌肉”产生的力是相同体积气缸的七倍。“流体肌肉”坚固耐用,即使是在沙滩或尘埃等极端环境中都可以使用。The pneumatic “fluidic muscle”, a completely new kind of pneumatic drive, is a development by Festo. The bionic muscles consist mainly of a hollow elastomer cylinder embedded with aramid fibres. When the fluidic muscle fills with air, it increases in diameter and contracts in length, enabling a fluid, elastic movement. The use of the fluidic muscle enables motion sequences which approach human movement not only in terms of kinematics, speed and strength, but also sensitivity. The fluidic muscle can exert ten times the force of a comparably sized cylinder, is very sturdy, and can even be used under extreme conditions such as in sand or dust.

自动风筝Sky_liner
放飞风筝需要娴熟的技能,Festo公司凭借其“空中自动化风筝”首次证实运用机电学原理可以实现风筝全程自动化控制。这是其在运用流动气流核心技术上的新发展。 “空中自动风筝”包含两个分别用机电控制器操纵的双线风筝。运用伺服电机和人造风,这两个风筝就可以实现室内自动化操作。各风筝线通过快速开关阀连接到Festo公司生产的DMSP射流臂,它可以缩短风筝线的长度。如果风筝断线,通过射流臂收缩风筝线就可以使其平稳飞行。It takes a fair amount of skill to fly a kite. With its Sky_liner project, Festo has become the first company to demonstrate that fully automated control can be achieved with the aid of mechatronics, thus linking a new development to its core competency of automation using moving air. Sky_liner consists of two two-line kites, each of which is controlled using a mechatronic control unit. The two kites are operated automatically indoors, using servo motors and artificial wind. Each line is connected via fast-switching valves to a fluidic muscle DMSP from Festo, which shortens the line and counterbalances the kite by contracting when the kite breaks away.
