目前我国生产的磁电式扭矩测量装置可以给出数字量形式的平均扭矩值,取样周期约15秒。如果需要扭矩的瞬时值,则只有模拟量可以利用。本文提出了一种新的二次仪表构成原理,它利用Z80—CTC的计数功能在微机控制下,不仅能以数字形式给出平均值,亦能以直接数字形式给出瞬时扭矩,特别适合于在数字系统中采用。 At present, China’s production of magnetoelectric torque measuring device can give the average amount of torque in digital form, the sampling period of about 15 seconds. If an instantaneous torque value is required, only the analogue can be used. This paper presents a new principle of secondary instrument composition, which uses the Z80-CTC counting function under the control of a microcomputer, not only in the form of digital average, but also in direct digital form gives instantaneous torque, especially suitable for Used in digital systems.
