Below, in conjunction with a specific example of an automatic standard sample verification scenario for online monitoring of water pollution sources, the solution of the embodiment of the present application is described in detail and explained:

In an embodiment of the present application, a method for automatic standard sample verification for online monitoring of water pollution sources is provided. The method can be applied to automatic standard sample verification for online monitoring of water pollution sources to effectively prevent enterprises from secretly discharging during the verification period.

Please refer to Figures 2 and 3. Figure 2 shows a schematic diagram of the device interaction of automatic standard sample verification, and Figure 3 shows a detailed flow chart of the standard sample verification method of the embodiment of the present application. The embodiment of the present application first obtains the automatic calibration time through the environmental data acquisition instrument, determines whether there is an automatic calibration plan for the next day, obtains a first judgment result, and determines whether there is an automatic calibration plan for the next day. The automatic calibration time includes two parameters: the calibration date and time and the calibration interval, which can be obtained by the environmental data acquisition instrument in different ways according to the actual application scenario:

① If the automatic calibration time is configured on the environmental data acquisition instrument, it can be directly obtained;

② If the automatic calibration time is configured on the automatic water quality analyzer, it can be obtained by reading the corresponding parameter information in the protocol of the automatic water quality analyzer.

According to the calibration start time and calibration interval of the next day's automatic calibration time, the calibration end time can be calculated for the subsequent determination of the standard sample verification time. Further, according to the next day's automatic calibration time and the last standard sample verification time, a random next day standard sample verification time is generated. Exemplarily, there are three situations for generating the next day's standard sample verification time (taking the time threshold of 4 hours as an example):

(1) When there is no automatic calibration plan for the next day, the computer code program on the environmental data acquisition instrument randomly selects an integer between 0-24 o'clock on the natural day to obtain the candidate standard sample verification time, and determines the time difference between the candidate standard sample verification time and the previous standard sample verification time. When the time difference is ≤4h, a random integer is selected again between 0-24 o'clock on the natural day to update the candidate standard sample verification time until the time difference of the standard sample verification is greater than 4h, then the candidate standard sample verification time is used as the standard sample verification time of the next day.

(2) If there is an automatic calibration plan for the next day, and the calibration start time is not 22:00 or 23:00, when generating the next day's standard sample verification time, the time point after the calibration is completed is fixed as the next day's standard sample verification time.

(3) When there is an automatic calibration plan for the next day, and the calibration start time is 22:00 or 23:00, the standard sample verification time for the next day is generated as usual (i.e., generated in the first case, but with an integer between 0-21:00), and when generating the standard sample inspection time for the third day, it is fixed to the hour after the calibration completion time (i.e., 0:00 or 1:00 on the third day). At the same time, the computer code program on the environmental data acquisition instrument randomly selects an integer between 0-21:00 on a natural day to obtain a candidate standard sample verification time, and determines the time difference between the candidate standard sample verification time and the last standard sample verification time. When the time difference is ≤4h, a random integer is selected again between 0-21:00 on a natural day to update the candidate standard sample verification time until the time difference of the standard sample verification is greater than 4h, and the candidate standard sample verification time is used as the standard sample verification time for the next day.

In the above case, the method of randomly picking an integer is:

Given non-integer n, a and c, for any integer z ^[0] , a sequence of integers z ^[k] is obtained by a recursive formula, which is called the first integer sequence. The recursive formula of this embodiment is expressed as:

z ^[k] = (az ^[k-1] + c) mod η

The modulus symbol mod means that z ^[k] is the remainder after az ^[k-1] + c is divided by η. Then divide z ^[k] by η to get a sequence of random numbers:

You can choose to use the rand() function in ANSI C and set its parameters to a＝1103515245, c＝12345, η＝2 ³¹ .

After obtaining the random number sequence, according to the value of the random seed, the value of the corresponding position in the random number sequence is taken as the current output random number. Among them, the value of the random seed must ensure that each execution is different from the previous one. Its value is the timestamp difference between the current execution time and the computer chip production time, in seconds.

The next day's standard sample verification time is generated by the environmental data acquisition instrument software system between 23:30 and 23:33 of the previous day to ensure the normal standard sample verification work. For example, tomorrow's standard sample verification time is generated between 23:30 and 23:33 tonight.

When the planned automatic standard sample verification time for the next day arrives, the environmental protection data acquisition instrument determines whether to issue an instruction. The environmental protection data acquisition instrument reads and determines the last standard sample verification time of the automatic water quality analysis: when the last standard sample verification time is the previous day, the standard sample verification instruction is issued to the automatic water quality analyzer, and the automatic water quality analyzer receives the standard sample verification instruction and automatically performs the verification work; when the last standard sample verification time is the same day, the standard sample verification instruction is canceled, and the generation of the standard sample verification time for the next day is not affected.

After receiving the standard sample verification instruction, the automatic water quality analyzer executes the standard sample verification instruction and performs the standard sample verification work.

When the automatic water quality analyzer obtains the standard sample verification result, the standard sample verification result is returned to the environmental protection data acquisition instrument, and the environmental protection data acquisition instrument uploads the standard sample verification result to the monitoring center platform.

In summary, the embodiments of the present application have at least the following beneficial effects:

1. By generating a highly random time on the hour by the host computer, a standard sample verification instruction is issued to the automatic water quality analyzer for standard sample verification. This is beneficial to effectively reduce the risk of enterprises secretly discharging during the verification period without affecting the normal operation of the automatic water quality analyzer and meeting the standard requirements. The solution of the embodiment of the present application also has the advantages of simple operation and easy implementation.

2. By calculating the interval between the candidate standard sample verification time and the last standard sample verification time and making a judgment, the generated standard sample verification time can meet the standard requirements, avoiding too short time interval between two standard sample verifications and avoiding waste of resources.

3. By judging the automatic calibration time, the generated standard sample verification time can be made not to coincide with the automatic calibration time, meeting the relevant standard requirements. Standard sample verification after calibration can not only verify the calibration at the first time, but also avoid performing standard sample verification twice on the same day, which can not only improve the measurement accuracy of the instrument, but also reduce the number of standard solution measurements, the amount of reagents used, and the amount of waste liquid discharged.

4. The environmental data acquisition instrument determines whether to issue instructions, which can take into account special standard sample verification scenarios. For example, a city stipulates that "the quality control inspection instrument will be started when the data exceeds the standard". In addition to the daily automatic standard sample verification, there is also a quality control verification link required due to exceeding the standard. Therefore, there may be multiple times a day. Under the premise of meeting the standard requirements, the number of unnecessary verifications should be reduced as much as possible. In addition, there may be situations where the verification fails. For example, if the verification fails, calibration and re-verification are required, and the cycle is repeated until the verification passes or the duration reaches 6 hours. If this process is carried out across natural days, the standard sample verification on the second day does not need to be repeated.

Referring to FIG. 4 , the embodiment of the present application further provides an automatic standard sample verification system 100 for online monitoring of water pollution sources, which can implement the above-mentioned automatic standard sample verification method for online monitoring of water pollution sources. The system includes:

The first module 101 is used to obtain the automatic calibration time, determine whether there is an automatic calibration plan for the next day, and obtain a first determination result;

The second module 102 is used to generate a random standard sample verification time for the next day according to the first judgment result and the last standard sample verification time;

The third module 103 is used to determine whether to issue a standard sample verification instruction when the next day standard sample verification time arrives, and obtain a second judgment result;

The fourth module 104 is used to send the standard sample verification instruction to the automatic water quality analyzer according to the second judgment result to perform the standard sample verification.
