In the test environment, the electrolytic cell 4 is brought into a stable operating state, wherein the stable operating state indicates an operating state at a stable operating current, an optimal water inlet temperature, an optimal water inlet flow. Multiple sets of sample data may be collected by adjusting the input current or input power. When the electrolytic cell 4 is an electrolytic cell for adjusting the input current, the input current set each time may be taken as one sampling current, and when the electrolytic cell 4 is an electrolytic cell for adjusting the input power, the sampling current set each time at the input power may be collected by the current collecting device 5.

In the embodiment, the stable multi-group voltage and current data are obtained through multiple tests when the electrolytic tank is in a stable working state, and the collected data in the stable state can more accurately reflect the stable working state of the electrolytic tank, so that the obtained voltage-current relation model is more accurate, the working abnormality of the electrolytic tank can be timely found when the working state of the electrolytic tank is monitored, the abnormality detection accuracy is improved, and technicians can conveniently take intervention measures in time.
In some embodiments, the voltage-current relationship model is a linear model u=kl+b 0, where U represents the voltage of the electrolytic cell, I is the current of the electrolytic cell, k, b 0 are parameters obtained by fitting the multiple sets of sampling data, the estimated error δ=max { |u i-(kIi+b0) | } and i=1, 2,3.
Specifically, through multiple stable operation tests, different sampling currents and sampling voltage average values corresponding to the different sampling currents are obtained, and are represented by (I i,Ui), i=1, 2, 3..n, and fitting the obtained (I i,Ui) by using a fitting method to obtain a voltage-current relationship model u=kl+b 0.
If the monitored working current is I 'and the measured voltage obtained by actual measurement is U Actual practice is that of in the working state of the electrolytic tank 4, substituting the monitored working current into a voltage-current relation model u=ki+b 0 to obtain an estimated voltage U' =ki '+b 0, and if |u' -U Actual practice is that of | > δ, the electrolytic tank 4 works in an unstable working state and the working state is abnormal. When the I U' -U Actual practice is that of I is less than or equal to delta, the electrolytic tank 4 works in a stable working state, and the working state is normal.
For example, when testing a certain electrolytic cell, the collected multiple groups of sampling data are as follows: (72, 29.6), (288, 30.8), (720, 32.6), (1080, 34), (1440, 36), (1728, 37), fitting the sets of sample data to obtain a voltage-current relationship model as shown in fig. 4. From the fitting results:
k＝0.00446，
b0＝29.37368，
δ＝max{|Ui-(kIi+b0)|}＝max{0.09，0.14，0.02，0.19，0.20，0.08}＝0.2。
For example, in the process of monitoring the electrolytic tank 4, the working current I '=1000a is obtained, and U' = 33.83 is calculated through the voltage-current relation model, so that when U Actual practice is that of < 33.63 or U Actual practice is that of > 34.03, the monitored measured voltage is an abnormal value, which indicates that the working state of the electrolytic tank 4 is abnormal.
