概述 目前,大型立筒式金属粮仓和砖仓已在国家粮库和国营农场大量使用。为保证安全储粮,必须解决仓内粮温检测问题。一个千吨粮仓,按粮储管理的要求,需要埋设16根测温电缆,每根电缆接有8个测温元件,即每仓共有测温点8×16=128个。一个大型仓群,一般拥有数十乃至数百个大型粮仓,即有数千到数万个测温点。为掌握粮情变化,必须对上述数千乃至数万个点的粮温随时进行采集、记录和分析。这一工作,依靠传统方法显然难以完成。建立微机粮温检测及处理系统则可使这一问题顺利解决。 系统应具有下列功能。
At a Glance Large, large-format, metal silos and brick silos are currently heavily used in national grain farms and state farms. In order to ensure the safe storage of grain, we must solve the grain temperature detection problem in the warehouse. A thousand tons of grain storage, according to the requirements of grain storage management, the need to lay 16 temperature cables, each cable connected to the eight temperature components, that is, each warehouse a total of temperature measurement point 8 × 16 = 128. A large warehouse, usually with tens or even hundreds of large granaries, that is, thousands to tens of thousands of temperature measurement point. In order to grasp the changes in the grain situation, it is necessary to collect, record and analyze the grain temperatures of the above thousands or even tens of thousands of points at any time. This work, obviously relying on traditional methods, can hardly be completed. The establishment of microcomputer food temperature detection and processing system can solve this problem smoothly. The system should have the following features.
