摘要
为满足缆道信号传输效率条件不同的测站要求,保证流速信号的可靠接收,安徽省水文局研制了BB.LJ系列流速记录仪。介绍了BB.LJ系列流速记录仪中流速测算、记录仪和水下编码信号源的原理、功能、技术特点,阐述了计算机和单片机技术,以及编、解码技术在水文仪器方面的应用。通过在安徽省10多个水文站的试用,论证了BB.LJ系列流速记录仪具有广泛的推广应用价值。
In order to meet the needs of different cableway signal transmission efficiencies to ensure reliable receiving of current meter＇s signals, BB.LJ series recorder for flow velocity was developed by Anhui provincial hydrology bureau. Flow velocity calculation method, recorder and underwater coding signal source principle, functions, technical features are introduced. The author expounds computer and single chip microcomputer technology, and application of coding ＆ decoding technology in hydrometric instrument as well. By the application of the recorder in more than 10 hydrological stations, it has verified its merit of wide generalization and application.
