Fish tank online monitoring method and system based on digital twinning

The invention discloses a fish tank online monitoring method and system based on digital twinning, and particularly relates to the technical field of intelligent fish tanks, and the system comprises a single-chip microcomputer, a temperature sensor, a water quality sensor, an oxygen sensor, a camera, a feeding module, an early warning module and a user interaction module. The method comprises the following steps: acquiring the internal temperature, water quality and oxygen data of a fish tank through a sensor, marking the data according to the internal video data of the fish tank, pre-training a deep neural network model through the marked data, and transmitting the pre-trained model to a single-chip microcomputer; sensor data and video data in a fish tank are fused through a monitoring system and transmitted to a digital twinborn model, finally scene simulation is conducted through a digital twinborn body according to data obtained by a sensor and a camera, and when a data value in a simulation scene exceeds
