Description

Technical Field

[0001] The invention relates to the technical field of navigation hubs, and in particular to a digital monitoring method for a high-head ship lock floating bollard and a data wired transmission device thereof. Background Art

[0002] In the field of water conservancy engineering technology, ship locks are important navigation structures on waterways, and their safe and efficient operation is crucial to ensuring smooth waterway traffic. In particular, ship lock systems in high head environments have higher requirements on the performance of ship lock facilities and their supporting equipment due to complex water flow conditions. As a key component for fixing ships in ship locks, the status monitoring and data transmission technology of floating bollards has always been the focus of the industry.

[0003] At present, the operation monitoring and daily inspection of floating bollards are all carried out by manual visual inspection, which has the following problems to be solved: under objective conditions such as low visibility, bad weather, and shielding between ships, the current visual supervision method through the image monitoring system has obvious disadvantages, and it is impossible to efficiently observe and confirm the operation status of each floating bollard, which affects the efficiency of passing the lock; with the development of large-scale ships, the mooring force of ships has greatly increased compared with the past, and even frequently exceeds the design upper limit. The equipment may be in an overloaded working state. From the perspective of operational safety, it is necessary to conduct effective, quantitative, active and real-time monitoring of the operation status of the bollard; especially the equipment defects such as jamming, structural damage and deformation during the operation of the floating bollard, and the operational safety hazards caused by the reciprocating flow at the end of the filling and discharge of water in the lock chamber are difficult to be discovered in time by visual inspection, and the floating bollard is adjacent to the waterside and the environment is harsh; the shielding caused by the large-scale ships and the location of the floating bollard make it impossible to achieve wireless transmission of monitoring signals. Therefore, it is necessary to develop a digital monitoring method and device for floating bollards in high-head ship locks.

[0004] In existing technical research, traditional sensors and wireless transmission methods are mostly used for monitoring floating mooring posts. Although these technologies have achieved real-time monitoring of the status of mooring posts to a certain extent, they often have problems such as inaccurate monitoring, signal attenuation, and unstable transmission under harsh working conditions such as high head and large flow, which affects the accuracy and timeliness of monitoring data. In addition, wireless transmission methods are also easily affected by external factors such as electromagnetic interference, which further increases the uncertainty of data transmission.

[0005] In order to solve the above problems, some patent documents, such as CN213014159U, disclose a floating bollard monitoring system, including a monitor, an information processing cabinet, a control center host computer, a voice alarm, and a light alarm. The monitor monitors the floating bollard in real time, and the monitor sends the collected information to the information processing cabinet, which organizes the information and sends it to the control center host computer. The operation of the bollard can be timely understood through the control center host computer. When the bollard is abnormal, the voice alarm and the light alarm are alarmed through the control center host computer through the information processing cabinet to remind the staff in time. The monitor includes a buoy reservoir, a floating bollard, a fixed bracket, and a displacement sensor. The buoy reservoir is pre-set on the wing walls on both sides of the lock chamber, the floating bollard moves up and down in the buoy reservoir, and the fixed bracket is installed on the wall of the buoy reservoir; the system uses a displacement sensor, i.e., a laser rangefinder, to realize real-time monitoring of the bollard. However, the technical solution still mainly relies on indirect monitoring and wireless transmission, and fails to fundamentally solve the problems of inaccurate monitoring and data transmission in a high head environment.

[0006] In summary, although the existing technology has made some progress in the digital monitoring and data transmission of floating bollards, there are still prominent problems such as unstable signals and susceptibility to interference, which makes it difficult to meet the high requirements of high-head ship lock systems for monitoring data accuracy and real-time performance. Therefore, it is necessary to develop a more stable and efficient data transmission device and method to overcome the shortcomings of the existing technology and improve the intelligent management level of the ship lock system.
