Wherein, described bank base treatment facility is positioned at water craft or position, bank, is connected with described digital signal processing appts by cable;
Wherein, described digital signal processing appts also reclaims driver with described electronic snap close, described fishing net release actuator and described fishing net and is connected respectively, when receiving described fish body and obtaining signal, adjust the distance according to first-phase and preset fishing net weight determination fishing net release dynamics; According to the fishing net of fish body deviation angle determination under water release angle, and send described fishing enabling signal to described electric lock garnishment.
3., as claimed in claim 2 based on the fishing method of data communication, it is characterized in that:
Described signal receiver waterborne is RS232 serial communication interface.
4., as claimed in claim 2 based on the fishing method of data communication, it is characterized in that:
Described gray processing process subset, described Iamge Segmentation subset, described background estimating subset, described background elevator equipment, described scattered light filtering subset and described target recognin integration of equipments are on one piece of surface-mounted integrated circuit.
5., as claimed in claim 2 based on the fishing method of data communication, it is characterized in that:
Described digital signal processing appts also monitors self resource occupation percentage in real time.
6., as claimed in claim 5 based on the fishing method of data communication, it is characterized in that:
Described digital signal processing appts is when the resource occupation percentage of self is less than predetermined percentage threshold, replace all operations of described background estimating subset, when the resource occupation percentage of self is more than or equal to predetermined percentage threshold, exit the replacement of all operations to described background estimating subset.
