Problems solved by technology

[0004] The current method has the following shortcomings: 1. Rainwater is easily polluted during the process of transporting from the field to the laboratory, which affects the representativeness of rainwater samples; The operation skills are very high, and it is easy to introduce human error; 3. The manual detection of rainwater ions requires a lot of work and labor input; 4. The pH electrode lacks automatic calibration, and the calibration and maintenance workload is large; 5. The rainwater pipeline is not cleaned, and the sample greater impact

Embodiment 1

[0021] Example 1: Full parameter detection in precipitation samples

[0022] Task requirements: realize the automatic collection of precipitation samples, and automatically measure the pH, conductivity, water temperature, fluoride ion concentration, chloride ion concentration, nitrate ion concentration, sulfate ion concentration, sodium ion concentration, ammonium ion concentration, Potassium ion concentration, magnesium ion concentration, calcium ion concentration.

[0023] 1. Automatic collection of precipitation: when it is raining, 1 rain funnel will automatically collect precipitation; when the precipitation stops, 1 rain funnel will stop collecting precipitation; the rain funnel will continue to collect precipitation in the environment according to this mode;

[0024] 2. Automatic delivery of precipitation samples: When the measurement time set by the system is reached, the 2 drainage electric ball valves are opened, and the rainwater samples in the 1 rain funnel are ext...

Embodiment 2

[0035] Example 2: pH electrode automatic calibration

[0036] Task description: Realize the three-point automatic calibration function of the pH electrode. When the automatic calibration task is started, the system performs the following steps:

[0037] 1. Extract pH1 calibration solution: 17 switch the three-way valve at the outlet of the syringe pump to the OUT terminal, switch the common end of the multi-channel selector valve to connect with 23pH calibration solution 1, and 17 inject 15ml of 23pH calibration solution 1 into the syringe pump; 18 The public end of the switch is connected to the 32pH measuring tank, and the 17 syringe pump delivers its internal liquid to the 32pH measuring tank;

[0038] 2. The 14pH electrode measures the pH1 calibration solution in the 32pH measuring tank to obtain the measurement signal;

[0039] 3. Cleaning of the pH calibration pipeline: 17 Switch the three-way valve at the outlet of the injection pump to the IN terminal, 17 The injecti...

Abstract

The invention provides an online rainfall monitoring system and an online rainfall monitoring method. The online rainfall monitoring system comprises a rainwater collection and conveying module, an EC / pH measurement module, an ion detection sample processing module and a reagent extraction and ion detection sample injection module, wherein the rainwater collection and conveying module is capable of controlling rainwater to be respectively conveyed to the EC / pH measurement module and the ion detection sample processing module through switching six measurement switching valves. The online rainfall monitoring system and the online rainfall monitoring method have the beneficial effects of realizing an online automatic measurement function for ion components in a rainwater sample, realizing an automatic alignment function of pH electrodes and realizing an automatic cleaning function of a rainwater pipeline and a reagent pipeline of the system.

Description

technical field [0001] The invention relates to an on-line precipitation monitoring system and method, belonging to the technical field of environmental protection and detection devices. Background technique [0002] Acid rain is an important environmental problem faced by our country, and precipitation monitoring is an important task in our environmental protection work. With the development of automation technology and analysis and detection technology in China, precipitation monitoring has gone through three stages: manual sampling monitoring, automatic sampling manual monitoring, and online monitoring. At present, the composition of precipitation online monitoring system at home and abroad is relatively simple. [0003] The working principle of the above-mentioned online monitoring system is explained: the rainwater in the rain funnel is pumped by the sample extraction peristaltic pump and transported to the conductivity measurement tank and the pH measurement tank, and...
