| 摘 要： | 本文提出了以通用阵列逻辑器件 GAL 和只读存贮器 EPROM 为核心器件的频率/待测量变换的设计方法。配以数字式传感器及用最小二乘法编制的曲线自动分段拟合程序生成的 EPROM 中的数据,可用于力、温度、光强等非电量的测量显示和控制。这种装置与采用微处理器的电路相比,有相同的测量精度,电路简单,而且保密性好.

| Abstract: | ——The designing method of measuring display controllers,with General Array Logical u- nits(GAL)and Erasable Programmable Read Only Memory(EPROM),is proposed.The generated data of EPROM are processed by a sectional curve fitting program acoording to the least square crite- rion.Associated with digital sensors,the controller can be applied to the measurement of force,tem- perature and light intensity.Compared with those using microprocessors,the proposed instrument has a similar measuring microprocessors,the proposed instrument has a similar measuring accuracy,but a simpler circuit and a better security function. |
