为了将美国国立耕耘机械实验室土槽的土壤坚实度测量车与仪器车分离,在土壤坚实度测量车上安装了微处理机,新的带微机的测量系统,不仅能测量测点在土槽中的座标,测头深度和坚实度力,还可在CRT上显示坚实度力相对于测头深度的曲线。所有的测量数据可传槽上采用了一台特殊制作的带土壤坚实度仪的测量车。该测量车为一独立单元,可沿土槽纵横向移动,坚实度仪测头则由液压驱动进行测输至国立耕耘机械实验室的中心计算机。本文探讨了硬件、软件和系统的操作功能。
In order to separate the soil solidity measuring car and the instrument car from the trough of the National Tillage Machinery Laboratory in the United States, a microprocessor and a new measuring system with a microcomputer are installed in the soil solidity measuring car, which not only can measure the measuring point in the earth trenches In the coordinate, probe depth and solid degree of force, but also on the CRT display solid force curve relative to the depth of the probe. All measuring data can be transferred to a special trough with a soil hardness tester. The measuring car is an independent unit that can move vertically and horizontally along the soil trough. The solidity measuring probe is hydraulically driven to the central computer of National Tailing Machinery Laboratory. This article explores the operational capabilities of hardware, software and systems.
