摘要
本文介绍了为我台人卫观测的打印经纬仪配套而研制的记时仪的性能.说明了单片机的应用推动天文仪器的更新换代.为观测质量的提高和资料处理自动化,展示了美好的前景.
The instrument specifications, hardware structure, software design and other char- acteristics of the chronograph mounting on a theodolite used for artificial satellite observation are presented in this paper.The instrument is a real time control system with a single chip microcomputer Intel 8031. Without EPROM inside INTEL8031, a programmable chip 2764 is used as the program memory, and a 6116 as the data memory.The high stable crystal oscillator generates the clock frequency. The precision of the record time can reach 0.001 s.there are 8 LEDs on the instrument, six for the display of hours, minutes and seconds, and two for the artificial satellite ID.A the TP-μp16B printer records the time with 9 digits with the last one being in ms.The operation is convenient and reliable.
