摘　　要：当前的船闸远程自动控制方法处理负载信号的方式较为单一,而负载信号的处理较为复杂且存在信息量不足的问题,因此需要更长时间来完成负载信息的处理和解析,进而导致无法即时有效地远程控制和调整船闸。为此,提出基于RTSP协议网络监控的船闸远程自动控制方法。首先,通过声波传感器对船闸负载信号进行采集,并对采集到的船闸负载信号进行变换处理,从而提高远程控制的准确率。然后,通过小波包分解法对船闸控制特征向量进行提取。最后,利用RTSP协议网络监控实现远程自动控制船闸。与现有方法比较的结果表明,所提方法在控制船闸时的响应速度最快,仅为0.2s,说明所提方法在实际应用中具有较高的应用价值,为水利工程领域的智能化、自动化发展提供了有力支持。The current remote automatic control methods for ship locks handle load signals in a relatively single way,and the processing of load signals is complex and has the problem of insufficient information.Therefore,it takes longer time to complete the processing and analysis of load information,and unable to achieve real-time and effective remote control and adjustment of ship locks.A remote automatic control method for ship locks based on RTSP protocol network monitoring is proposed.Firstly,the ship lock load signal is collected through acoustic sensors and transformed to improve the accuracy of remote control.Then,the feature vectors of the ship lock control are extracted using wavelet packet decomposition method.Finally,the RTSP protocol network monitoring is used to achieve remote automatic control of the ship lock.Comparison with methods in other literature shows that,the proposed method has the fastest response speed when controlling ship locks,only 0.2 s,indicating that the proposed method has high application value in practical applications and provides strong support for the intelligent and automated development in the field of water conservancy engineering.
