深水网箱网衣破损监测系统设计

针对在深水网箱网衣破损监测研究中出现的问题,提供了一种全新的网箱网衣破损监测方法和监测系统,可在浑水区实时监测网衣情况.系统由单片机、网片检测电路、开关矩阵和GSM手机模块组成.在网衣内编入导线,使网衣成为一种网破传感器.系统将网衣分成多块网片,并对网片进行编码.网片破损处与海水、入海电极形成回路,触发手机模块发出报警短信,指出网箱的编号和网衣破损部位.当系统与网衣出现连接故障时也可触发手机模块发出报警短信,指出故障网箱的编号和故障部位.

Design on Cage Net Crack Detecting System of Sea Cage

Aiming at the problems of the cage net crack detectability, a new cage net crack detecting method and detecting system were designed. The facility, equipped with single-chip microcomputer, cage net crack detecting circuit, switch matrix and cellular phone module could detect the situation of cage net crack in muddy water area with lower power consumption and low cost. The net slice could become a cage net crack sensor by weaving lead and nylon into it. The system divided cage net into many net slices, and coded each one. As soon as one of the net slices was cracked, the loop between the damaged position, sea water, and the sea electrode were formed and it made the system send short message to the user by cellular phone module, showed the serial number of cracked sea cage and the information of crack part. When the conjunction breakdown between the system and the net slices were appeared, it could also make the system send short message to the user, showed the sea cage's serial number and the information of break part.
