　　洋馬升級自主駕駛拖拉機，三大亮點更實用

洋馬宣布升級其自主駕駛拖拉機系列，該系列拖拉機能夠完全或部分自主作業(yè)。新版本將于2021年4月1日起在日本上市。

Yanmar has announced the upgrade of its autonomous tractor series, which are capable of full or partially autonomous work. The new versions will go on sale in Japan from April 1st, 2021. 

近年來，日本的大規(guī)模農(nóng)業(yè)有所增加，這是由小型農(nóng)場并入大型企業(yè)所帶來的。與此同時，農(nóng)業(yè)人口的減少和老齡化導(dǎo)致日本農(nóng)業(yè)勞動力短缺。為了應(yīng)對這些挑戰(zhàn)，可自主駕駛農(nóng)業(yè)機械市場正在崛起。洋馬升級的機器人/自主駕駛拖拉機將采用多頻率天線，以實現(xiàn)穩(wěn)定連接和更高的定位精度，從而實現(xiàn)更安全、更高效的自主駕駛拖拉機。

Recent years have seen an increase in large scale farming in Japan, brought on by consolidation of smaller farms into larger enterprises. At the same time, a declining and aging farming population has led to workforce shortages in Japanese agriculture. The market for autonomous agricultural machinery is rising to meet these challenges. Yanmar’s upgraded robot/auto tractors will utilize a multi-frequency antenna for stable connection and higher positioning accuracy towards a safer, even more efficient autonomous tractor. 

洋馬農(nóng)業(yè)企業(yè)總裁Nagamori Masuda說：“洋馬的自主駕駛拖拉機和機器人拖拉機因其效率、可靠性和準(zhǔn)確性而受到農(nóng)業(yè)界的青睞。”有了這些新型號產(chǎn)品，洋馬可以提供更具魯棒性的定位技術(shù)，使田間作業(yè)更具靈活性，從而為農(nóng)民提供更大的價值?！?/span>

“Yanmar’s auto tractor and robot tractor have found favour in the farming community for their efficiency, reliability and accuracy,” said Nagamori Masuda, Yanmar Agribusiness president. “With these new models, Yanmar offers farmers even more value with more robust positioning technology that allows even greater flexibility in the field.”

洋馬將繼續(xù)努力滿足客戶的需求，為可持續(xù)農(nóng)業(yè)做出貢獻。

Yanmar will continue to work to meet customer’s needs, contributing to a sustainable agriculture. 

特征Features 

（1）多頻天線，定位更快

（1）Multi-frequency antenna for faster positioning 

多頻天線通過接收來自GNSS衛(wèi)星的三個不同頻率的信號，即使信號在其中一個頻率中斷，也能確保安全駕駛。此外，定位時間減少了75%，使工作能夠在到達現(xiàn)場后立即開始。

By receiving signals at three different frequencies from the GNSS satellite, the multi-frequency antenna can ensure safe driving even if the signal is interrupted on one of the frequencies. In addition, the positioning time is reduced by 75% allowing work to commence soon after arrival at the field. 

（2）虛擬參考站（VRS）通過擴展RTK覆蓋范圍實現(xiàn)更大的便利性

（2）Virtual Reference Station (VRS) mea s greater convenience through expanded RTK coverage 

以前，通過同時接收來自GNSS衛(wèi)星的信號和來自基站的校正信號，可以達到±3厘米。

Previously, by receiving both signal from the GNSS satellite and a correction from a base station, it was possible to achieve precision of ±3cm. 

現(xiàn)在新系統(tǒng)接收多頻率信號，允許拖拉機接收本地參考點定位數(shù)據(jù)，通過VRS確定其位置。這意味著不再需要安裝洋馬基站，該系統(tǒng)可以在任何移動信號可用的地方使用。

The new system receives a multi-frequency signal allowing the tractor to receive local reference point positioning data to determine its position via VRS. This means it is no longer necessary to install a Yanmar base station and the system can be used anywhere mobile signal is available. 

VRS需要使用校正信號服務(wù)。

VRS requires use of a correction signal service. 

（3） 允許更低速度的精準(zhǔn)做業(yè)（最小：0.5 kph）

（3） Lower speed (min: 0.5 kph) allows precision work 

增加的定位穩(wěn)定性允許新的工作類型。由于拖拉機的定位具有非常高的魯棒性，因此可以在低至0.5 kph的更低速度下進行精確作業(yè)。以前無法完成的任務(wù)，如聯(lián)合耕作和起壟，現(xiàn)在可以由機器人拖拉機執(zhí)行。

Increased positioning stability allows for new kinds of work. Because the positioning of the tractor is highly robust, it is possible to carry out precision work at lower speeds as low as 0.5 kph. Previously inaccessible tasks such as combined tilling and ridging can now be carried out by the robot tractor.
