Abstract

The invention relates to a ship entering and leaving detection system based on a piezoelectric hydrophone and solves the technical problem that the existing ship entering and leaving detection equipment is poor in detection effect. The ship entering and leaving detection system comprises a PC (personal computer), a sound-light alarm, a lighting set, a wireless transceiving module and a detection unit. The sound-light alarm, the lighting set and the wireless transceiving module are all connected with the PC. The detection unit is connected with the wireless transceiving module. The ship entering and leaving detection system is widely applicable to entering and leaving detection for ships.

Description

technical field [0001] The invention relates to a detection device, in particular to a detection system for ships entering and leaving a port based on piezoelectric hydrophones. Background technique [0002] Every year during the fishing ban period in our country, fishing boats are found to go to sea in violation of regulations. After some illegal fishing boats are detained by the regulatory authorities according to law, they often go to the protected areas or bases of the regulatory authorities at night to steal the seized ships. [0003] At present, the following methods are available for the inspection of ships entering and leaving the port: [0004] (1) Detection by shipboard GPS [0005] Fishing boats are equipped with on-board GPS, which can be used to locate the boat and then determine whether the boat is in port. However, fishing boats that violate the regulations turn off or shield the GPS, so that the regulatory authorities cannot obtain the location information ...
