In addition, the present invention has a good sealing effect as a whole, reaching the waterproof IP68 level. And each module can be tested for sealing performance. Even if water enters the interior, it will not cause damage to the internal modules.

[0045] Control Methods

[0046] The whole system is divided into two working states; one is the sleep mode, in which the power supply of the analysis module, the filtering module 5 and the first analysis module 1 will be disconnected; only the main control module 4 will be operated; the other is the working mode, in which there are at least the following four triggering modes: one is interval analysis, one is hourly analysis, one is tidal analysis, and one is manual triggering analysis. The type of working analysis can be manually adjusted so that the main control module 4 can control the remaining modules individually and / or as a whole.

[0047] Interval analysis: After the user sets the interval and turns on the corresponding switch, the instrument counts according to the internal clock. When the preset time is reached, the system is triggered to start the process and reset the timing.

[0048] Hourly analysis: Users can freely set multiple time points. The instrument compares the internal clock value with the preset value, and triggers a system process every time the hours and minutes are equal.

[0049] Manually triggered analysis: After the user manually clicks, the system immediately starts a system process.

[0050] Tidal analysis: The user can preset the number of minutes before or after high tide or low tide, and preset the number of analyses. The system calculates the analysis time based on the user's preset value and the tide schedule. Whenever the analysis time is equal to the internal clock hour and minute, the system process is triggered.

[0051] After any of the above working modes is triggered and analyzed, the main control module 4 controls the entire system through the following control methods:

[0052] ① The main control module 4 powers on the five-parameter first analysis module 1, waits for the first analysis module 1 to power on and buffer, and then triggers the first analysis module 1 cleaning brush to act through a notification instruction to eliminate bubbles or impurities that may be covered on the electrode; then waits for the first analysis module 1 to buffer, records the five-parameter measurement results, and disconnects the power supply of the five-parameter first analysis module 1;

[0053] ② The main control module 4 controls the filtration to filter the water sample, waits for the main control module 4 to receive the water sample signal detected by the liquid level detector, and continues to run for a certain period of time, then stops the action of the filtration module 5, and controls each analysis module to perform analysis through the communication protocol;

[0054] ③ After each analysis module gives a signal indicating the end of sampling, the main control module 4 continues to control the filter module 5 to backwash and backwash the pipelines in the sampling and filter module 5;

[0055] ④ After receiving the analysis end instruction from each analysis module, the main control module 4 collects and records the analysis results and time of each analysis module, sends them to the data transmission module in the main control module 4 and uploads them to the designated platform;

[0056] ⑤ Automatically enter sleep mode after completing the analysis process;

[0057] The electric energy required for the above two working modes is provided by the battery pack 6, and the solar panel 13 can supplement the electric energy. The power supply logic and charging logic of the battery pack 6 are controlled by the control method 2.

[0058] The main control module 4 controls a single module as follows:

[0059] 1. Control method of the main control module 4 on the power supply system:

[0060] By acquiring the power and voltage information of multiple battery groups, a determination is made based on the capacity of each battery group 6, and when the capacity of the boom battery group 6 is greater than the capacity of the battery group 6, the battery group 6 is used to power the entire system and charge the battery group 6. Vice versa.

[0061] 2. Control method of the main control module 4 on the filtration system:

[0062] ① After receiving the filtering instruction, the main control module 4 controls the opening of the filtering valve and the filtering pump 55, extracts the sample from the filter 51, passes through the liquid level detection column, and then passes through the filtering valve and the filtering pump 55 and is discharged from the NW pipe (non-toxic waste liquid pipe); after the liquid level sensor 53 detects the sample signal, it transmits the signal to the main control module 4. After receiving the filtered liquid level sensor 53 signal, the main control module 4 continues to control the operation of the filtering module 5 for a certain period of time, and then stops the action of the filtering module 5; waits for the next instruction;

[0063] ② After receiving the backwash instruction, the main control module 4 controls the switches of the backwash valve, the cleaning valve and the filter pump 55, draws the cleaning liquid through the cleaning valve, the backwash valve, the filter pump 55, and the liquid level detection column, and then discharges it through the filter 51, and uses the cleaning liquid to clean the filter 51, the filter pipeline and the liquid level detection column; then closes the cleaning valve, draws air from the air pipe, and passes through the cleaning valve, the backwash valve, the filter pump 55, and the liquid level detection column, and then discharges it through the filter 51, and empties the residual liquid in the filter 51, the filter pipeline and the liquid level detection column to prevent the growth of algae;

[0064] 3. Control method of main control module 4 to analysis module:

[0065] After receiving the analysis instruction, the main control module 4 controls each analysis module to trigger the analysis process, extracts the filtered samples for analysis, and after the analysis module completes the analysis, the main control module 4 collects the data in the analysis module for aggregation and storage.
