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

Embodiment Construction

[0038]The structure and method of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0039] figure 1 It is a schematic diagram of the network structure of a large-scale data collection method for pond aquaculture water bodies according to the present invention. Network nodes are composed of personal area network (PAN) coordinator, full function device (FFD) and reduced function device (RFD). Network Coordinator FFD, which acts as a network control center, acts as a network router. When the network status changes, other FFDs can also act as a coordinator, and the wireless network can be constructed into a star topology and a peer-to-peer network topology.

[0040] When building a peer-to-peer network, the coordinator first sets itself as the cluster head and sets the cluster ID (CID) to 0 to form the first cluster in the network. The coordinator selects an unused PAN identifier and broadcasts beaco...

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, ...
