Pond culture water multi-parameter acquisition system and method

Abstract

The invention relates to a pond culture water quality monitoring system and a pond culture water quality monitoring method, in particular to a pond culture water multi-parameter acquisition system and a pond culture water multi-parameter acquisition method. The pond culture water multi-parameter acquisition system comprises a water quality data acquisition node and an on-site wireless communication network, wherein the on-site wireless communication network is based on Institute of Electrical and Electronics Engineers (IEEE)802.15.4 communication protocol; the network node of the on-site wireless communication network comprises a personal area network (PAN) coordinator, a full-function device (FFD) and a reduced-function device (RFD); the on-site wireless communication network is constructed into star topology and peer-to-peer network topology; and the data acquisition node comprises a water quality sensor and a wireless network transceiver, and after receiving sensor data, transmits water quality data to a wireless network periodically. In the invention, water quality data can be acquired in a large-scale culture fish pond in real time for regulating the quality of the water in the culture pond and automatically controlling on-site equipment.

Description

(1) Technical field [0001] The invention relates to the establishment of a monitoring system and method for water quality of pond aquaculture water, in particular to a system and method for real-time collection of large-scale, multi-parameter water quality data of pond aquaculture water. (2) Background technology [0002] Freshwater pond culture is the basic way of fish culture in my country, with a history of more than 3,000 years. In recent years, the area of ​​pond aquaculture is about 2.5 million hectares, accounting for about 30% of the total area of ​​freshwater aquaculture in the country, and the output is 15 million tons, accounting for more than 70% of the total output of freshwater aquaculture in the country. my country's freshwater fishery is in the leading position in the world in terms of aquaculture area, total aquaculture output and aquaculture yield per mu. Pond farming is not only an important guarantee for the supply of high-quality protein in my country, ...

Problems solved by technology

However, due to the high price of imported sensors and other reasons, the project investment is high, and it is difficult to popularize and apply it. Aquaculture units are few in number using the online monitoring system for aquaculture water quality.

[0004] At present, my country's pond aquaculture water quality monitoring technology is derived from industrial aquaculture monitoring technology. The main problems in the application of industrial aquaculture monitoring technology in pond aquaculture water quality monitoring are: (1) the existing aquaculture water quality monitoring system monitors the water quality of large-area pond aquaculture. The applicability of continuous, timely and accurate collection of water quality parameters and their changes is insufficient; (2) The system’s networking technology is single, and the data bus communication structure is used on site. The self-organizing network technology scheme has not been applied and reflected, and is difficult to realize Large-scale data transmission; (3) Industrial aquaculture monitoring technology is difficult to apply to the characteristics of pond aquaculture such as scattered areas, field settings, and harsh working conditions, resulting in high equipment failure rates, or high construction costs are not suitable for large-scale installation and application; (4) In addition, most of them use imported test instruments, which require high investment and are rarely used in aquaculture in ponds.

WiFi transmission data rate is high, power consumption is large, it is difficult to provide external power supply for each water quality monitoring terminal in large-scale pond culture in remote areas. Water body data detection
