【正文】 emotely monitor all the sluice gates on the Yellow river and realize centralized dispatch of water volume and optimal allocation of water resources.Keywords: Yellow river, sluice gates, remote monitoring, quality control1. Preface The sluice gates of Yellow river are distributed along the whole downstream banks, and the management is inconvenient due to their wide distributing space, bad field condition and plicated system constitution. The technical transformation to these sluice gates by using modern sensor technology, electronic technology, and network and munication technology would realize remote monitoring for these sluice gates, viz. field measuring and video monitoring.Field measure and control system is the core and foundation for the sluice gates remote monitoring system and all the message collection, transmission and response is on the basis of it. By video access terminal and control decoder, the video camera can be controlled to rotate, zoom and lens selfcleaning. All the images are pressed and transmitted to the sluice gate management department by video input terminal and munication network, then could realize field management and control. Meanwhile, these images are also transmitted to water volume allocation system of Yellow river by internet switch and wireless munication and used by water allocation centers at all levels. In order to guarantee the 3D image’s continuity and realtime demand on monitor terminal at all levels, the equipments has adaptation function and can automatically adjust image transmit to optimal state. The sluice gates monitoring system has following functions:（1）Video information of water condition before and after the sluice, environment condition, sluice chamber condition are collected by video camera and digitalized and pressed. （2）The pressed data are transmitted to gate management department by internet, and then practice field management and control。（2）The analog acquisition cycle: electricity 2s, nonelectricity 10s。（4）The update cycle of realtime database: 2s。 mand implementation response time1s。 ReliabilityThe control system and the equipment can adapt the working environment, has high antiinterference ability and steadily run in a long term. The MTBF parameters of the equipment are as follows: The monitor puter of the gate management department16000h。 Maintainability The system hardware and the software is easy to maintain, measure and repair.（1）The equipment has selfdiagnosis function。（3）Equipped with special in(un)stall tools。（5）Exchange or unexchange ponents can be acknowledged。（7）The software can be changed and plemented easily。（2）when meeting wrong operation it would be forbid to operate automatically。 Guarantee measures for munication safety（1）The system design can ensure not lead to key system failure under message error in transmit。（3）The equipment of information pipe fixed checking tools, then ensure it is formal。（2）Selfcheck ability and autowarning when failure is found。（4）Any ponent failure can not lead to error running of the equipments. ExtendibilityIn order to guarantee the monitor extendibility on adding gates number or gate extension construction, the system has extendibility on following aspects:（1）Backup points number is not less 20% of the running equipments。（3）Prepare interface at field control unit and system municat
