Embodiment Construction

[0028] (1) Detection node design

[0029] The detection node includes a data processor MSP430, a wireless transmission unit nRF2401, a sensing acquisition unit and a power supply unit. The temperature sensor adopts digital temperature sensor DS18B20, The value sensor adopts the model H-101, the dissolved oxygen sensor adopts the DO-957 polarographic dissolved oxygen sensor, and the signal conditioning circuit uses a low-power chip design amplifier circuit. The entire programming process adopts a modular design, mainly including equipment initialization, data acquisition and processing, and wireless communication modules. The detection node collects data periodically, and the collection time interval is set to 30 min. The detection node sends the locally collected data to the gateway node through the wireless sensor network. The hardware structure of the detection node is as follows: Figure 4 shown.

Abstract

The invention discloses an aquaculture pond PH value control system with a wireless sensor network. The system is composed of an aquaculture pond environment parameter collection and control platform and an aquaculture pond PH value cascade control system based on a composite controller. The aquaculture pond PH value control system with the wireless sensor network is designed according to the characteristics of the large working condition area of aquaculture pond environment PH value parameters, the nonlinearity and large lag of PH value changes, the unbalanced distribution of the pond PH value and the like. The system has huge application and popularization value in improving the stability of control over the aquaculture pond PH value and increasing the economic benefit of aquaculture.

Description

technical field [0001] The invention relates to the technical field of intelligent control equipment, in particular to an aquaculture pond based on a wireless sensor network value control system. Background technique [0002] PH value is a comprehensive indicator reflecting the water quality of aquaculture water, and an important comprehensive factor affecting fish activities. One of the water environmental conditions in fishery production It is very important to control the value. Excessive reduction or increase of the value will directly endanger the fish, and even cause the death of the fish, even if it is not fatal sometimes, because the value exceeds the tolerance level of the fish, it will lead to physiological dysfunction. And affect its growth or cause other diseases. the fish When the value is lower than 5.5, the oxygen-carrying capacity of the blood will be weakened, causing the fish to suffer from physiological hypoxia, weakened activity, reduced metaboli...
