It is understood that aquaculture butlers are mainly divided into three parts, namely, the perception layer, transmission layer and application layer. Perceptual layer can be understood as a person's body feeling by analogy. For example, when a hand touches a cup, it will feel hot when it is boiled, and ice water will feel cold. The transport layer is the process of network communication, which transmits information perceived by the sensing layer to the application layer. The application layer is equivalent to the human brain, comprehensively processing the perceived information, and then issuing instructions to implement the application service. Between the three, the transport layer is the channel, connection awareness layer and application layer.
It is understood that in the technical aspects of the aquaculture butler, the transmission layer and the application layer, China's technology has been very similar to that of foreign countries. However, there are still gaps between the sensor layer and the foreign technology. Since China has not fully grasped the core technologies such as sensor manufacturing and satellite resources, there is a certain gap between the performance indicators such as stability, reliability, accuracy, and power consumption of most products and foreign products.
In the use of smart phones, if the shrimp is cultured, the aquaculture housekeeper's sensor needs to be cleaned once every two weeks, while the cultured fish need to be cleaned once a week. If there is a problem with the equipment, the manufacturer will send someone to maintain it. The maintenance will not require extra payment, and the replacement of the parts will require payment. During the process of use, due to the turbidity of the aquaculture water, occasionally, suspended matter adheres to the probe, thus affecting the sensitivity. Since the effects of domestic sensors have not yet reached an optimal level, why not use foreign sensors? The reason is that foreign sensors are expensive and difficult to maintain.
