该系统是根据秦山核电站二期工程的有关课题要求的技术指标,结合STD-BUS总线微机的特点,研制成功的气象七要素微机采集处理系统。1991年11月在现场正式投入运行,一年内数据获取率达到90％以上。是一种气象观测先进手段和仪器。系统分两个部分,即七种气象传感器及其A/D转换电路和STD总线结构的工业控制微型计算机及其接口电路。对雨量和太阳光总辐射能量两种传感器设计了V/F电路。所有传感器在正式运行前都进行了标定刻度。为了适应野外恶劣环境,选用了具有优良性能的STD总线结构的工业控制微机作为数据采集处理的主机。选用HD64180CPU芯片构成控制模板,配STD-8701-64kB内存模板以及STD-8006智能化通用小型键盘,μP-16打印机组成了基本微机系统。设计一块八位戈瑞码接口和一块12路计数接口电路模板把传感器与微机之间连接起来。用汇编语言编制相应的程序软件,构成了气象地面站的微机数据采集处理系统。
The system is based on Qinshan Nuclear Power Station Phase II project requirements related to technical indicators, combined with the characteristics of STD-BUS bus microcomputer, developed a successful meteorological seven elements of computer acquisition and processing system. In November 1991 formally put into operation on the spot, within one year data access rate reached 90%. Is a meteorological observation of advanced means and instruments. System consists of two parts, namely, seven kinds of weather sensors and their A / D converter circuit and STD bus structure of industrial control microcomputer and its interface circuit. V / F circuit is designed for two kinds of sensors such as rainfall and solar radiation. All sensors are calibrated before they are officially operational. In order to adapt to the harsh environment of the field, the industrial control microcomputer with STD bus structure with excellent performance is selected as the host for data acquisition and processing. Use HD64180CPU chip composition control template, with STD-8701-64kB memory modules and STD-8006 intelligent universal small keyboard, μP-16 printer composed of the basic computer system. Design an eight-bit Golay code interface and a 12-channel count interface circuit board to connect the sensor and the computer. Using assembly language to compile the corresponding program software, constitute the meteorological ground station computer data acquisition and processing system.
