ABB在汉诺威展上展示其最新无线技术

The latest advances in ABB’s wireless technology at Hanover Fair

汉诺威展上ABB无线技术的最新技术

2007-04-25 - ABB last week showed off its most advanced wireless technologies for use in industrial automation at the world’s largest industrial fair in Hanover, Germany, including wireless communication for real-time connectivity between instruments and control rooms, and wireless power supplies that allow devices to operate without power cables or batteries.

2007-04-25——上周，ABB在全球最大的工业展览会德国汉诺威展上展示了其应用于工业自动化的最高端无线技术，包括用于仪器和控制室之间实时连接的无线通信，以及允许设备无需电线或者电池就可以工作的无线供电技术。

ABB’s WISA (wireless interface to sensors and actuators) technology at Hanover Fair targeted applications in industrial automation and encompasses both wireless communication (WISA-com) and wireless power supplies (WISA-power). These help customers reduce the amount of complex cabling in their plants, cutting costs and commissioning times.

ABB的WISA（传感器和制动器无线接口）技术在汉诺威展上把目标对准了在工业自动化上的应用，而且包含了无线通信(WISA-com)以及无线供电(WISA-power)。这些技术帮助客户减少了在工厂里复杂的布线量，节省了成本和调试时间。

“Cabling is a common point of failure in automation systems, so its removal enhances reliability and reduces downtime,” said Peter Terwiesch, Chief Technology Officer at ABB. “It’s particularly practical in harsh environments.”

ABB首席技术官Peter Terwiesch表示：“电线是自动化系统常见的一个失败点，所以它的移除增强了可靠性，减少了停工时间，在恶劣的环境里它尤其实用。”

If cabling is removed, device mechanics can often be simplified because strain and wear on the wires no longer needs to be avoided, and the possibilities for remote monitoring systems are expanded.

一旦电线可以移除，设备的结构往往就可以简化，因为无需再避免电线的拉力和磨损，而远距离监控系统的可能性也就增大了。

Wireless communications
无线通信

Wireless is useful in production cells and assembly lines (for example, power train or motor assembly, production machines); robot applications and material-handing (for example, palletizers); packaging machines; and machines for the food and beaverage industry (proportioning machines).

无线技术主要用于：生产设备和装配线（例如，传动系或者电机装配、专用机床）；机器人应用和材料传递（比如，码堆机）；包装机器；以及食品和饮料工业的机器（比例配料机械）

ABB sensors equipped with WISA technology communicate using the IEEE-standard radios, as used in Bluetooth devices. To accommodate the hundreds of devices found in a typical industrial plant, ABB developed its own communications protocol based on duplex Time Division Multiple Access (TDMA) technology and frequency hopping, which enable data to side-step interference from neighboring devices and achieve 99.99 percent reliable transmission.

ABB具有WISA技术的传感器利用IEEE标准的无线电通信，和在蓝牙设备上使用的一样。为了适应一般工厂里的众多设备，ABB是基于双重的时分多址连接技术(TDMA) 和跳频技术开发其通信协议的，从而使数据可以避开邻近设备的干扰，达到99.99%的可靠传输率。

Wireless power
无线供电

Because of the large number of devices involved, ABB rejected the idea of battery power for many of its wireless sensors and developed an ingenious solution in the form of a rotating magnetic field generated by electric cables that surround the work area. The sensors pick up energy from the field and convert it into usable power to drive monitoring and communications functions.

因为涉及的设备数量较多，ABB否决了对其众多无线传感器利用电池供电的理念，而是开发了一个独创性的解决方案，通过工作领域周围的电线产生的旋转磁场供电。传感器从磁场获得能量，从而转化成可用的电力，推动监测和通信功能。

Thanks to high-volume production of consumer electronics, the cost of wireless technology has fallen significantly in recent years and, although it is widely applicable, WISA technology does not address all the needs of wireless factory automation.

由于消费电子的大量生产，近些年来无线技术的成本已经大大下降，而且，尽管其应用广阔，WISA技术也无法满足无线工厂自动化的所有需要。

Different types of sensors will need different types of networks and ABB has teamed up with FESTO and Millennial Net in an informal collaboration that aims to meet these challenges head on. ABB and FESTO will provide expertise in wireless sensor and actuator technologies. and Millennial Net expertise in mesh networking.

不同类型的传感器需要不同类型的网络，而ABB已经与FESTO和 Millennial Net一起进行了一个非正式的合作，对付所面临的这些挑战。ABB和FESTO将提供无线传感器和制动器方面的技术，而Millennial Net则提供网状网络方面的技术。

Broad application
应用广阔

The technology used in the WISA family of products has many uses, from controlling pumps and valves to directing spot-welding robots. ABB has a long history in wireless technology and is well placed to broaden the applications of its proven technologies.

应用于WISA产品家族的技术具有许多用途，从控制泵和阀门到指挥点焊机器人。ABB在无线技术方面具有很长的历史，可以充分地扩大其经过验证的技术的应用范围。
