Cooperating management of farm machinery operation

在农活中，常常有几台机器同时运转。研究的目的是使这些机器有效地协同工作。在这项研究中，以下三个主题进行了研究。(1)有效的合作方法；(2)一台机器与其他机器之间的通信方法；(3)农用车上的位置自我识别。有效的合作方式。合作农场作业分为串联、并联和复合作业。采用数字化方法对复合农场作业中的牧草收获作业进行了模拟。与每个操作人员各自独立操作的情况相比，协作方法是有效的。沟通的方法。对数字信号的A-t第一调频无线通信进行了尝试。但由于无线电波控制规律的限制，导致有效通信距离不足。将bc波段无线电收发机应用于水稻收获作业中进行了试验。联合收割机的操作和通讯没有问题。尝试了用bc波段收发器进行分组无线通信，该方法效果良好，但还需要进一步的实验。农用车辆的自我识别。为了确定农用车在田间的位置，在每辆农用车上检测车辆的角速度和运行速度，并将各信号进行综合，做出农用车的位置决策。通过调查，估计该方法是可行的。

On the farm work, often a few machines operate at the same time. The purpose of the study is to make effective cooperation of these machines. On this study following three subjects were researched. (1)effective cooperation method, (2)communication method from a machine to other machines, (3)self-recognition of position on the farm vehicles.1. Effective cooperating method. Cooperative farm work were classified to series, parallel and compound operations. One of the compound farm operation, forage harvesting operation were simulated by digital method. Cooperative method was effective compared with a case that each operators worked independently by their mind.2. Communication method. A-t first FM wireless communication of digital signal was tried. But the effective communication distance was shortage by limitation of radio wave control law. Using BC-band transceiver was tried on the rice harvesting operation as noisy farm work. There were no problem on the combine harvesting operation and communication. Packet wireless communication with BC-band transceiver was tried, the method was good but it was required continued experiments.3. Self-recognition of farm vehicle. For the decision of farm vehicle position in the field on each farm vehicle, angular velocity and running velocity of the vehicle was detected and each signals were integrated and decision of the position was made. By the investigation, it was estimated that this method was practical.
