Embodiment 1

[0027] A water quality detection method provided by an embodiment of the present invention includes: obtaining a water sample to be tested; the turbidity detection module detects the turbidity value of the water sample to be tested and uploads it to the water quality detection module; the PH value detection module detects the pH of the water sample to be tested The value is uploaded to the water quality detection module; the temperature detection module detects the temperature value of the water sample to be tested and uploaded to the water quality detection module; the water quality detection module transmits the turbidity value, PH value, and temperature value of the water sample to be tested to the cloud platform through the wireless network.

[0028] The above water quality detection method integrates multiple sensors and transmits the detection data to the cloud platform in real time, which can monitor various water quality parameters online and improve water safety.

Embodiment 2

[0030] Another water quality detection method provided by the embodiments of the present invention includes the following three steps:

[0031] Step 1: The incident light emitted by the light-emitting element on one side of the water sample to be tested enters the water sample to be tested, and the forward light-receiving element on the other side of the water sample to be tested receives the transmitted light after passing through the water sample to be tested. If the output signal to the light-receiving element is greater than the detection threshold, the forward calibration light intensity is obtained according to the output signal of the forward-direction light-receiving element, otherwise, replace the water sample to be tested and measure again.

[0032] Among them, when the water sample to be tested is too dirty, it is not conducive to the subsequent measurement of turbidity and ion concentration, so the transparency measurement is performed first to ensure that the water...

Embodiment 3

[0046] In order to better realize the water quality detection method in the second embodiment, the embodiment of the present invention also provides a corresponding water quality detection system, such as image 3 As shown, it includes: sampling device 1, reagent adding device 2, photoelectric detection device 3, main control device ( figure 1 not shown).

[0047] The sampling device 1 includes a water inlet 11 and a water outlet 12. The water outlet 12 is provided with a sampling solenoid valve 13. The water inlet 11 is connected to the water source of the water sample to be tested through a pipeline, and the liquid to be tested is controlled by opening and closing the sampling solenoid valve 13. Sampling to facilitate real-time testing of water quality.

[0048] Reagent adding device 2 comprises reagent tube 20, and reagent tube 20 comprises reagent adding port 21 and reagent outlet 22, and reagent outlet 22 is provided with reagent electromagnetic valve 23, adds the reagen...

Description

technical field [0001] The invention specifically relates to a water quality detection method and system. Background technique [0002] As people continue to pay attention to urban terminal water supply and drinking water, more quantitative index requirements are put forward for the traditional tap water supply system and the water quality of purified water. Generally, to obtain the results of water turbidity, hardness and residual chlorine content, water samples need to be taken and sent to the laboratory to obtain data through spectral analysis. The cycle is long and the cost is high, and it is impossible to achieve timeliness, informatization, networking and civilian practicality. Especially with the development of modern technologies such as the Internet + and the Internet of Things, there is an urgent need for a method and equipment that can continuously monitor water turbidity, hardness and residual chlorine online in environmental monitoring, urban water supply system...
