Problems solved by technology

[0003] (1) The biggest disadvantage is that it requires a lot of human participation and cannot automatically detect a water area intelligently
Secondly, manual detection of water areas requires a lot of manpower and material resources, and the detection efficiency is not very high.
The water quality detection of a certain river area or lake is mostly point-type detection, that is, a target detection point is randomly selected for random detection. The method requires too much manpower, cost and time
Therefore, most of the time, it is a small-scale manual detection with few sampling points. It is difficult to find the pollution source in a timely and effective manner and take timely and effective control measures, and it is also impossible to accurately locate the pollution source;
[0004] (2) Although it has multi-functional properties, the cumbersome measurement methods, a large amount of data and complex operations require the participants to have more accurate and correct operating procedures to obtain more accurate measurement data
These modules are not well integrated, which leads to the cumbersome and complicated use of testing instruments;
[0005] (3) It is impossible to form a complete and efficient system, that is, a system that includes intelligent detection, data upload, analysis, and positioning of polluted areas, etc., and provides timely feedback after detection
When the waters are polluted by humans or nature, it cannot be detected early and effectively treated, leading to further spread and aggravation of pollution

[0042] Through the above settings, the upper part is a cylinder with a height of 75mm and a roun...

Embodiment 2

[0044] see image 3 It is the schematic diagram of temperature detection circuit, including temperature sensor DS18B20, and the control communication positioning module includes MSP430 chip. The temperature sensor DS18B20 uses an I / O port to communicate with the microprocessor MSP430 chip in two directions. The power supply is 3V-5.5V, and the measurement results are serially transmitted in 9-12 digits without any external components.

Embodiment 3

[0046] see Figure 4 , is the schematic diagram of the pH detection circuit, including pH electrode P1, TL431 chip U1, AD8663 chip U3 and two LM358 chips U2.1 / U2.2, wherein the pH electrode P1 generates a corresponding DC voltage change according to the pH change in the water, To convert the PH value signal into an electrical signal, the built-in ADC in the MSP430 chip collects a positive voltage of 0-2.5V, and the output voltage of the PH electrode P1 includes negative voltage. It is necessary to add a reference voltage to the PH electrode P1 as a bias, so that the output voltage is all Positive voltage, use TL431 chip U1, short its pin 1 and pin 2, get a stable output voltage on pin 1, and then divide the voltage through the sliding rheostat R2, and transmit the generated reference voltage to an LM358 chip U2 On the pin 3 of .1, connect its pin 1 and pin 2 to form a voltage follower, which is used for impedance isolation of the input terminal of the PH electrode P1 to ensure...

Description

technical field [0001] The invention belongs to the field of inspection and detection, and relates to a light-duty intelligent water quality detection system and method. Background technique [0002] The existing water pollution detection device is an environmentally friendly water quality detector that completes the detection of five basic water quality parameters: temperature, pH value, dissolved oxygen content, turbidity and conductivity. The detection process requires manual carrying of the device to the target detection area, use the collection device, and detect the collected water samples and collect data. When it is necessary to detect a certain range of river areas in a flowing manner, the device needs to be brought manually Go to ships and other water vehicles for testing. There are following deficiencies: [0003] (1) The biggest disadvantage is that it requires a lot of human participation, and it cannot automatically detect a water area intelligently. Secondl...
