摘要
目前在野外重力观测中普遍使用的国产重力仪,不具有自动记录和数据预处理功能,采用手工记录、人工计算方式。这种方式效率低,还容易引入一些由手工操作而带来的误差。本文所介绍的以PC-1500A袖珍计算机和数据采集接口实现的重力仪读数自动记录及数据预处理系统,可按规范要求自动记录重力观测读数,从而可防止野外记录和室内转抄计算时产生的差错,减少了大量的数据转抄、校对、复算、检查等繁琐劳动,极大地提高了重力观测的质量和效率。
The domestic gravimeters without the capability to auto-record and prep-rocess data are widely used in fields at present. They are low in efficiency and lia-ble to make errors because of manual record and computation. This paper introduces a system for data auto-recording and preprocessing to improve the domestic gravime-ter by a specific device consisting of a pocket computer PC-1500A and a data collecting circuit. Gravimeter with this system is able to complete data-recording automatically and accord with the standard specifications. It is either able to avoid careless mistakes and reduce a lot of work including transcription, check, recalculation and rectification. The system designed in this paper can greatly improve the gravity survey quality and raise its efficiency.
