the third controller 1045 is configured to, when the component concentration of the electrolyzed liquid does not meet the first preset requirement, control the second power assembly 1044 to operate, so that the electrolyzed liquid in the storage assembly 1042 returns to the third device 103 through the fourth pipeline 14 to be electrolyzed again until the component concentration of the electrolyzed liquid meets the first preset requirement.

Here, the third controller 1045 is connected to the second power assembly 1044, the connection relationship between the third controller 1045 and the second power assembly 1044 is not shown in fig. 1, and the third controller 1045 may be connected to the second power assembly 1044 in a wireless connection manner.

In this embodiment, the second power assembly 1044 is a mechanism for controlling the electrolyzed liquid to flow back to the third apparatus 103 for re-electrolysis. As an example, the second power assembly 1044 may be a pump, and may specifically be a peristaltic pump. As shown in fig. 1, the second power assembly 1044 is a peristaltic pump B.

For ease of understanding, the fourth device 104 is illustrated herein as including a first sensor 1041, a storage assembly 1042, a second switch 1043, and a second power assembly 1044, which may be, as an example, a reservoir module including a valid chlorine sensor, a reservoir, a solenoid valve B, and a peristaltic pump B. The slightly acidic electrolyzed water leaves the electrolytic bath and firstly enters the liquid storage bin. The chlorine and the water need to react for a sufficient time, and if the reaction is insufficient, the conditions of low effective chlorine concentration, chlorine leakage and the like of the slightly acidic electrolyzed water are caused, so the chlorine and the water need to be firstly put into a liquid storage bin for full reaction. An effective chlorine sensor is arranged in the liquid storage bin and used for monitoring the effective chlorine concentration of the subacid electrolyzed water in the liquid storage bin in real time.

If the effective chlorine concentration meets the requirement, the electromagnetic valve B is opened, and the subacid electrolyzed water is output to the water outlet.

If the concentration of the effective chlorine is higher, the electromagnetic valve B is closed to prevent the outflow of the slightly acidic electrolyzed water which does not meet the requirement; starting a peristaltic pump B, pumping the high-concentration subacid electrolyzed water in the liquid storage bin, and then refluxing the electrolyzed water into an electrolytic bath for secondary electrolysis; the pumping speed of the peristaltic pump A is reduced, and electrolyte is pumped at a low speed to enter an electrolytic cell for electrolysis so as to reduce the effective chlorine concentration of the prepared subacid electrolyzed water; the electrolytic current and voltage of the electrolytic cell are reduced, and the electrolytic efficiency is reduced, so that the effective chlorine concentration of the prepared subacid electrolyzed water is reduced; and after the effective chlorine concentration measured by the effective chlorine sensor is reduced to a normal range, opening the electromagnetic valve B, and outputting subacid electrolyzed water meeting the requirements to a water outlet.

If the effective chlorine concentration is lower, closing the electromagnetic valve B to prevent the outflow of the slightly acidic electrolyzed water which does not meet the requirement; closing the electromagnetic valve A, and forbidding the water path from flowing in so as to improve the effective chlorine concentration of the prepared subacid electrolyzed water; the pumping speed of the peristaltic pump A is increased, and the electrolyte is highly pumped into the electrolytic bath for electrolysis so as to increase the effective chlorine concentration of the prepared subacid electrolyzed water; the electrolytic current and voltage of the electrolytic cell are improved, and the electrolytic efficiency is improved, so that the effective chlorine concentration of the prepared subacid electrolyzed water is improved; and after the concentration of the effective chlorine measured by the effective chlorine sensor is increased to a normal range, opening the electromagnetic valve B, and outputting the slightly acidic electrolyzed water meeting the requirements to a water outlet.

In the above description, the adjustment of the effective chlorine concentration in the storage tank involves the adjustment of the current and voltage values of the peristaltic pump a, the peristaltic pump B and the electrolytic cell, and all the adjustment adopts a Back Propagation (BP) neural network algorithm to dynamically adjust the current and voltage values of the peristaltic pump a, such as the peristaltic pump B and the electrolytic cell, according to different effective chlorine concentrations and waterway flow rates.

For ease of understanding, the BP neural network is described herein. The BP neural network is an error back-propagation network, adopts a layered structure, has better classification and memory capacity and high operation speed, the topological structure of the BP neural network is shown as figure 2, the figure 2 is a schematic diagram of the BP neural network topological structure provided by the embodiment of the invention, the topological structure is divided into 3 layers, if an input layer and an output layer reach ideal values, the BP neural network is directly output, if the BP neural network exceeds expected values, the BP neural network is back-propagated, and weights of all layers are continuously modified until the output values reach set values.

The BP neural network algorithm is realized by the following specific steps:

1) Setting an initial weight:

initial weights are set for the input layer, the hidden layer and the output layer.

2) Given a sample:

let the input and output of the P-th group of samples be respectively:

in the formula, L represents the number of input/output groups.

3) And (3) calculating and outputting:

when the P-th group of samples is input, the node i outputs an expression as follows:

in the formula, Q _jp The j input of the node i when the p group of samples is input; f is an excitation function, a Sigmoid type is adopted, and the input of the network output layer node can be obtained from an input layer to an output layer through a hidden layer.

4) Calculating an objective function E of the network at the time of sample input _p Comprises the following steps:

/>

in the formula, y _kp (t) is the network output after t times of weight adjustment when the p group of samples are input, and k is the jth node of the output layer.

5) Calculating a total objective function:

each set of objective functions E _p Superimposed overall objective function E:

6) Calculating deviation:

the total objective function E (t) and the selected desired value E ₀ A comparison is made. If E (t) is less than or equal to E ₀ Direct output is not calculated any more; if E (t) > E ₀ The reverse error propagation calculation continues.

7) Reverse error transfer calculation:

the inverse error transfer is calculated by the gradient descent method. And when the step length is eta, the weight between the neuron j and the neuron i is adjusted as follows:

the BP neural network gradually approximates the relation between input and output by using the continuously adjusted reverse error transfer calculation method until a satisfactory fitting relation is found.

In the invention, the values of the peristaltic pump A, the peristaltic pump B and the electrolytic bath current and voltage to be adjusted are calculated by utilizing the BP neural network according to the effective chlorine concentration and the water flow velocity in the liquid storage bin.

In this embodiment, the slightly acidic electrolyzed water generated at the first time is pre-stored, and then the concentration of the effective component is measured by the effective chlorine sensor. If the standard is met, the electromagnetic valve is opened and the water enters the water outlet. If the standard is not met, adjusting the electrolyte amount or refluxing the produced liquid for secondary electrolysis to obtain the subacid electrolyzed water meeting the standard.

In the embodiment, the current and voltage values of the peristaltic pump A, the peristaltic pump B and the electrolytic cell are calculated by applying the BP neural network according to the measured effective chlorine concentration and the water flow velocity, and the dynamic adjustment can be efficiently carried out on the effective chlorine concentration, so that a user can flexibly use electrolyte with various concentrations to adapt to the flow velocity of public water sources in various regions.
