Quality control method and device for water quality monitoring system

Abstract

The invention relates to a quality control method of a water quality monitoring system, and an apparatus thereof. The quality control method comprises the following steps: the water quality monitoring system transmits monitoring data, a detection signal, correction information and alarm code information to a management platform through a signal transmission module, and the management platform verifies data according to the monitoring data, the detection signal and the correction information; the management platform judges a sample checking result according to the monitoring data of a sample and the standard information of the sample; the management platform judges a reserved sample checking result according to reserved sample monitoring data and reserved sample checking data; and the management platform determines water sample monitoring data is effective if the alarm code information shows that no faults exist, data verification shows that data is uncorrected, the reserved sample checking result judges that the monitoring data is trusted, and a standard sample checking result and a water sample adding standard recovery rate prove the credibility of the monitoring data. The method and the apparatus have the advantages of accurate and reliable monitoring data, and remote control.

Description

technical field [0001] The invention relates to control equipment for a water quality monitoring system, in particular to a quality control method and device for a water quality monitoring system. Background technique [0002] During the application process of the water quality monitoring system, the water quality monitoring site mainly entrusts a third-party operation and maintenance company to carry out operation and maintenance. It can only be executed on-site, and it is more time-consuming and labor-intensive for remote sites. At present, the following problems exist in the operation and maintenance process of water quality monitoring stations: [0003] 1. Drifts or failures are inevitable during the operation of the water quality monitoring system. During the operation and maintenance process, it is impossible to know the measurement performance of the monitoring system and the accuracy of the measurement data in real time. It is necessary to start the standard sample ...

Problems solved by technology

[0003] 1. Drifts or failures are inevitable during the operation of the water quality monitoring system. During the operation and maintenance process, it is impossible to know the measurement performance of the monitoring system and the accuracy of the measurement data in real time. It is necessary to start the standard sample test on site and wait for the data to come out. to judge;

[0004] 2. In the process of operation and maintenance, it is impossible to know in real time whether there is matrix interference in the water sample measurement. It is necessary for people to take water samples on site, add the water samples, and then measure the water samples before and after the addition, and wait for the data to come out and calculate The recovery rate can only be judged after adding the standard;

[0005] 3. When the water sample exceeds the standard, it is impossible to judge in time whether the concentration of the water sample exceeds the standard or the system failure is caused;

[0006] 4. In the process of operation and maintenance, system performance evaluation is generally carried out by preparing standard samples or adding standard recovered samples. This method is an indirect verification of the reliability of monitoring data. There is no sufficient direct evidence on whether the monitoring data in the non-verification period is accurate and reliable. evidence
