Embodiment Construction
[0049] The present invention will be described in detail below with reference to the drawings, such as figure 1 , 2 Shown: Slope type dock barge mooring rope load monitoring and early warning system, including: acceleration sensor, signal processing module and server.
[0050] among them:
[0051] The acceleration sensor is fixedly arranged on the mooring rope of the ramp-type wharf barge, and is used to collect the vibration acceleration signal of the mooring rope.
[0052] The signal processing module is arranged in the signal box, and the signal box is arranged on the side of the mooring point of the dock mooring rope. The signal processing module is used to collect the signal of the acceleration sensor and transmit it to the server after processing; the signal processing module specifically includes a signal conditioning circuit, an A / D conversion circuit and a wireless communication module.
[0053] The signal conditioning circuit is used to collect the signal obtained by the acc...

The invention relates to the technical field of wharf security monitoring and controlling and provides a load monitoring and early warning system and method for a mooring rope of a slope type wharf boat. The load monitoring and early warning system and method is suitable to manual wharf mooring, particularly to load monitoring and controlling of the mooring rope of the slope type wharf boat without frequent mooring or unmooring operation. The system comprises an acceleration sensor, a signal processing module and a server. The acceleration sensor is fixedly arranged on the mooring rope and used for collecting vibration acceleration signals of the mooring rope. The signal processing module collects and processes signals of the acceleration sensor, thereby transmitting the processed signals to the server. The server receives data sent from the signal processing module, calculates and compares the load of the rope with preset threshold value and sends early alarming signals. According to the arrangement, rope load measurement is free of quick releasing hooks, and professional improvement to the wharf mooring equipment is omitted. The load monitoring and early warning system and method has the advantages of convenience, practicability and excellent anti-jamming capability, is suitable to most conventional mooring ropes in China and has lowest influence on wharf operation.
Description
Technical field [0001] The invention relates to the technical field of wharf safety monitoring, in particular to a mooring rope load monitoring and early warning system and method. Background technique [0002] The load mechanism of the mooring ropes of the sloping wharf barge is quite complicated. In addition to environmental factors such as wind, waves and currents, it is also related to the ship’s tonnage, ship type, deadweight, berth water depth, mooring method, cable technical status, barge and berthing A series of factors such as the interaction of ships are related. When the load of the rope is greater than its breaking force, a cable breaking accident may occur, affecting the loading and unloading operations of the terminal, and the barge generally has no self-propelled ability. Once it loses control and drifts down, it will pose a great threat to downstream terminals, sailing ships, bridges, and dams. It is hard to estimate the loss of life and property. It is necessar...
