葛洲坝水利枢纽是长江干流上目前最大的水利工程。葛洲坝船闸自动化也是大家关心的问题。目前,我国已建船闸,其运行方式多为手动或半自动操作,只有江苏省吕四船闸,应用光电技术实现了船闸控制自动化,达到了“船闸启闭不用人,船来船往自开门”。几年来的实践证明,光电探测技术在船闸控制方面的应用,还有一定的局限性,特别在上下游水位变幅大的情况下,加上波浪影响,很难使发射和接收装置同步和对准,此外还受阳光、阴
Gezhouba Dam is the largest water conservancy project on the Yangtze River. Gezhouba Ship Lock automation is also everyone’s concern. At present, China has built shiplocks, which are mostly manual or semi-automatic mode of operation, only Jiangsu Province, Lu four locks, the use of optoelectronic technology to achieve automatic control of the ship lock, reached the “lock not open, the ship to the door.” Several years of practice have proved that the photoelectric detection technology in ship lock control, there are some limitations, especially in the case of large upstream and downstream water level changes, coupled with the impact of waves, it is difficult to synchronize the transmitting and receiving devices and the right In addition, also by the sun, overcast
