【文章內(nèi)容簡介】 the state monitoring.（2）It can realize the realtime monitoring of the water level before and after the sluice and the environment in the sluice chamber.（3）It can realize the field and remote surveillance of the environment before and after the sluice and the surrounding.（4）It can realize the protection when the sluice hoist is excess or overload.（5）It can realize the voice munication among the sluice gates place, the Provincial Bureau, and the Yellow River Conservancy Commission.3. Quality Control of the SystemThe quality controls of remote monitoring system mainly include the quality control of the system realtime performances, the reliability, the availability, the CPU load rate, the security, the expansive capacity, and the quality control of the system software. realtime performancesMonitoring system can satisfy the need of time in the data collection, humanputer munication, control and system munication.（1）The digital collection cycle: ＜1s。（2）The analog acquisition cycle: electricity 2s, nonelectricity 10s。（3）The resolution of the sequence of events record: ≤ 5ms。（4）The update cycle of realtime database: 2s。（5）The response time of control mand: Command answer response time1s。 mand implementation response time1s。 （6）Humanputer munication response time: the response time of a new mand for calling a new image to display on the monitor2s。 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。The field monitoring equipment PLC30000h。 Maintainability The system hardware and the software is easy to maintain, measure and repair.（1）The equipment has selfdiagnosis function。（2）The system has breakpoint for experiment and failure isolation。（3）Equipped with special in(un)stall tools。（4）Premaintenance minimize the wearing failure 。（5）Exchange or unexchange ponents can be acknowledged。（6）Improve the substitution ability。（7）The software can be changed and plemented easily。（8）The average maintenance time of a failure is in 30ms. Available rateThe system design should adopt high reliability ponents, the realtime operating system should has practical running experience, the software should be practical, then the system can obtain high availability. The total failure time of the system should not exceed 1% of the running time during the oneyear guarantee time of after one year trial operation and equipment acceptance check. CPU loading rateThe processing ability of the monitoring puter has sufficient adequacy and ability storage over 50%, the CPU ability storage of PLC over 20%. System safetyThe specific measures for the system safety on operation, munication, hardware, software and fixed ware are as follows. Guarantee measures for operation safety（1）Every function and operation of the system has check and verification, warning and cancel would be took place when error is founded 。（2）when meeting wrong operation it would be forbid to operate automatically。（3）A control right mand is used on manputer munication。 Guarantee measures for munication safety（1）The system design can ensure not lead to key system failure under message error in transmit。（2）When the high level o
