洋马升级自主驾驶拖拉机，三大亮点更实用

洋马宣布升级其自主驾驶拖拉机系列，该系列拖拉机能够完全或部分自主作业。新版本将于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. 

近年来，日本的大规模农业有所增加，这是由小型农场并入大型企业所带来的。与此同时，农业人口的减少和老龄化导致日本农业劳动力短缺。为了应对这些挑战，可自主驾驶农业机械市场正在崛起。洋马升级的机器人/自主驾驶拖拉机将采用多频率天线，以实现稳定连接和更高的定位精度，从而实现更安全、更高效的自主驾驶拖拉机。

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. 

洋马农业企业总裁Nagamori Masuda说：“洋马的自主驾驶拖拉机和机器人拖拉机因其效率、可靠性和准确性而受到农业界的青睐。”有了这些新型号产品，洋马可以提供更具鲁棒性的定位技术，使田间作业更具灵活性，从而为农民提供更大的价值。”

“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.”

洋马将继续努力满足客户的需求，为可持续农业做出贡献。

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

特征Features 

（1）多频天线，定位更快

（1）Multi-frequency antenna for faster positioning 

多频天线通过接收来自GNSS卫星的三个不同频率的信号，即使信号在其中一个频率中断，也能确保安全驾驶。此外，定位时间减少了75%，使工作能够在到达现场后立即开始。

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）虚拟参考站（VRS）通过扩展RTK覆盖范围实现更大的便利性

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

以前，通过同时接收来自GNSS卫星的信号和来自基站的校正信号，可以达到±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. 

现在新系统接收多频率信号，允许拖拉机接收本地参考点定位数据，通过VRS确定其位置。这意味着不再需要安装洋马基站，该系统可以在任何移动信号可用的地方使用。

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需要使用校正信号服务。

VRS requires use of a correction signal service. 

（3） 允许更低速度的精准做业（最小：0.5 kph）

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

增加的定位稳定性允许新的工作类型。由于拖拉机的定位具有非常高的鲁棒性，因此可以在低至0.5 kph的更低速度下进行精确作业。以前无法完成的任务，如联合耕作和起垄，现在可以由机器人拖拉机执行。

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.
