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

漢諾威展上ABB無(wú)線技術(shù)的最新技術(shù)

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在全球最大的工業(yè)展覽會(huì)德國(guó)漢諾威展上展示了其應(yīng)用于工業(yè)自動(dòng)化的最高端無(wú)線技術(shù)，包括用于儀器和控制室之間實(shí)時(shí)連接的無(wú)線通信，以及允許設(shè)備無(wú)需電線或者電池就可以工作的無(wú)線供電技術(shù)。

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（傳感器和制動(dòng)器無(wú)線接口）技術(shù)在漢諾威展上把目標(biāo)對(duì)準(zhǔn)了在工業(yè)自動(dòng)化上的應(yīng)用，而且包含了無(wú)線通信(WISA-com)以及無(wú)線供電(WISA-power)。這些技術(shù)幫助客戶減少了在工廠里復(fù)雜的布線量，節(jié)省了成本和調(diào)試時(shí)間。

“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首席技術(shù)官Peter Terwiesch表示：“電線是自動(dòng)化系統(tǒng)常見(jiàn)的一個(gè)失敗點(diǎn)，所以它的移除增強(qiáng)了可靠性，減少了停工時(shí)間，在惡劣的環(huán)境里它尤其實(shí)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.

一旦電線可以移除，設(shè)備的結(jié)構(gòu)往往就可以簡(jiǎn)化，因?yàn)闊o(wú)需再避免電線的拉力和磨損，而遠(yuǎn)距離監(jiān)控系統(tǒng)的可能性也就增大了。

Wireless communications
無(wú)線通信

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).

無(wú)線技術(shù)主要用于：生產(chǎn)設(shè)備和裝配線（例如，傳動(dòng)系或者電機(jī)裝配、專用機(jī)床）；機(jī)器人應(yīng)用和材料傳遞（比如，碼堆機(jī)）；包裝機(jī)器；以及食品和飲料工業(yè)的機(jī)器（比例配料機(jī)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技術(shù)的傳感器利用IEEE標(biāo)準(zhǔn)的無(wú)線電通信，和在藍(lán)牙設(shè)備上使用的一樣。為了適應(yīng)一般工廠里的眾多設(shè)備，ABB是基于雙重的時(shí)分多址連接技術(shù)(TDMA) 和跳頻技術(shù)開(kāi)發(fā)其通信協(xié)議的，從而使數(shù)據(jù)可以避開(kāi)鄰近設(shè)備的干擾，達(dá)到99.99%的可靠傳輸率。

Wireless power
無(wú)線供電

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?yàn)樯婕暗脑O(shè)備數(shù)量較多，ABB否決了對(duì)其眾多無(wú)線傳感器利用電池供電的理念，而是開(kāi)發(fā)了一個(gè)獨(dú)創(chuàng)性的解決方案，通過(guò)工作領(lǐng)域周圍的電線產(chǎn)生的旋轉(zhuǎn)磁場(chǎng)供電。傳感器從磁場(chǎng)獲得能量，從而轉(zhuǎn)化成可用的電力，推動(dòng)監(jiān)測(cè)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.

由于消費(fèi)電子的大量生產(chǎn)，近些年來(lái)無(wú)線技術(shù)的成本已經(jīng)大大下降，而且，盡管其應(yīng)用廣闊，WISA技術(shù)也無(wú)法滿足無(wú)線工廠自動(dòng)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.

不同類型的傳感器需要不同類型的網(wǎng)絡(luò)，而ABB已經(jīng)與FESTO和 Millennial Net一起進(jìn)行了一個(gè)非正式的合作，對(duì)付所面臨的這些挑戰(zhàn)。ABB和FESTO將提供無(wú)線傳感器和制動(dòng)器方面的技術(shù)，而Millennial Net則提供網(wǎng)狀網(wǎng)絡(luò)方面的技術(shù)。

Broad application
應(yīng)用廣闊

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.

應(yīng)用于WISA產(chǎn)品家族的技術(shù)具有許多用途，從控制泵和閥門到指揮點(diǎn)焊機(jī)器人。ABB在無(wú)線技術(shù)方面具有很長(zhǎng)的歷史，可以充分地?cái)U(kuò)大其經(jīng)過(guò)驗(yàn)證的技術(shù)的應(yīng)用范圍。
