Abstract: In order to solve the problem of wireless image
transmission in fish pond, a wireless intelligent image sensor node is
designed in this study. The hard ware processing platform combines Chip
CC2530. Image frame, which is collected by the serial camera, is divided
into numerous data packets which are transmitted through ZigBee protocol one
by one. Canny edge detection algorithm is used to edge extract image data in
order to detect if there are any loss of data packets during the process.
The divided data packets are transmitted through the network, and eventually
the environment image of the fish pond was formed. According to the
experiment, the Relay Node added with power amplifier can perform the
information bridge between the Image Acquisition Node and the Image
Receiving Node effectively and realize the remote transmission of data.
Meanwhile, the loss rate of data packets is low, and the node has
retransmission function if there is loss of data packets. Realizing the
collection and transmission of the environment image in the pond, the node
can satisfy the requirements of fish pond environment monitoring.
