Description
Technical Field
The invention relates to the technical field of deodorization, in particular to a toilet deodorization self-adaptive control method and a toilet deodorization self-adaptive control system.
Background
At present, most of the existing toilet deodorizing devices adopt a plasma sterilization and deodorization air purification technology, and the working mechanism is as follows: the plasma is fully contacted with odor molecules, and the aim of deodorization is fulfilled by destroying the molecular structure of the odor clusters. The effectiveness of the device in deodorizing depends on the concentration of the plasma and the efficiency of the reaction with the odor molecules. The toilet deodorization device adopts a negative pressure fan to suck odor into the device, primary deodorization treatment is carried out through an ion tube, and air rich in ions is discharged out of the device and enters a toilet space to realize secondary deodorization treatment. Therefore, the deodorization performance can be controlled by controlling the air volume and the ion number, and the rotating speed of the negative pressure fan and the voltage of the ion tube in the deodorization device are correspondingly controlled, namely the deodorization performance of the device is controlled by controlling the power of the negative pressure fan and the power of the ion tube.
There are two main power regulation modes of existing toilet deodorising apparatus. One is an open-loop fixed mode in which the fan speed and the ion tube voltage are fixed and the deodorizing power of the device is also fixed. Before the equipment is put into use, the working mode is set by equipment installers according to the field environment and self experience, and the output power of the equipment can be manually adjusted in the running process of the equipment. In this mode, the deodorizing performance of the device is completely dependent on personal experience, and the output power is always set according to the maximum deodorizing requirement on site, so that there are problems that the power consumption is high, the device cannot adapt to the environmental change of the toilet, and the like. The other is a closed loop regulation mode, in which the rotation speed of the fan and the voltage of the ion tube are dynamically regulated along with the change of the air quality of the toilet, and the deodorization power of the device is dynamically adjustable. And in the running process of the equipment, acquiring real-time data of odor concentration according to a built-in environment monitoring sensor, and adjusting output power according to the deviation from a set value. In this mode, the closed-loop regulation allows real-time control of the odor concentration, but there is a hysteresis of the regulation, which makes the user experience poor, i.e. the odor can be gradually eliminated by the output power of the regulating device only after the odor is diffused in the toilet space, especially when the deodorizing device is installed in the upper area of the inner wall of the toilet, the closed-loop regulation of the deodorizing device can be triggered only after the odor generated on the toilet seat of the toilet is diffused into the upper space of the toilet, so there is a hysteresis of the regulation, which makes the user experience poor.

Fig. 1 shows that this embodiment discloses a toilet deodorization adaptive control method, which specifically includes the following steps:
step 1, acquiring an output power strategy of the deodorization device in previous N operation periods, wherein N is more than or equal to 1, and the output power strategy is the output power of the deodorization device at each moment in the corresponding operation period;
step 2, carrying out mean value statistics on the output power strategies of the N operation periods in the step 1 to obtain an initial output power strategy of the current operation period;
step 3, operating the deodorizing device in an initial output power strategy in the current operating period, and finely adjusting the actual output power of the deodorizing device based on the odor concentration of the environment where the deodorizing device is located on the basis of the initial output power strategy in the operating process of the deodorizing device;
step 4, after the current operation period is finished, storing the actual output power of the deodorization device in the current operation period as an output power strategy of the current operation period;
and 5, repeating the steps 1-4, and entering the deodorization control of the next operation period.
It should be noted that the power-adjustable deodorization device in the above control method refers to an air purification device adopting a plasma sterilization and deodorization technology, and the output power of the deodorization device is controlled to control the number of ions in the air in the toilet space, so as to further control the sterilization and deodorization effect and realize the control of the air quality in the toilet.
The control method in the embodiment can sample the toilet environment data in real time, and adaptively adjust the actual output power of the deodorizing device according to the odor concentration in the toilet environment; meanwhile, the actual output power is used as historical data to be stored and recorded, and an output power strategy suitable for the toilet environment where the deodorization device is located is constructed through analyzing the historical data; the deodorization device carries out deodorization operation according to the constructed output power strategy, and dynamically adjusts the output power according to the odor concentration in the toilet environment, thereby realizing the self-adaptive control of the application scene and the environment. The method adopts data analysis and self-adaptive algorithm to dynamically adjust the working mode of the sterilization and deodorization device, realizes the intellectualization of the sterilization and deodorization device for the toilet, improves the adaptability of the deodorization device to the application scene, improves the efficiency and reduces the energy consumption.
It should be noted that, in the above control method, if the current operation cycle is the first operation cycle, the initial output power policy is as follows: the deodorizing device has the same output power at each moment in the operation period. If the current operation cycle is the second operation cycle, N =1 in step 1; if the current operation cycle is the third operation cycle, N =1 or 2 in step 1; if the current operation cycle is the fourth operation cycle, N =1, 2 or 3 in step 1; and if the current operation period is the nth (N > 4) operation period, N in the step 1 is any one of 1-N. In the actual application process, in each operation period after the second operation period, the specific value of N in the corresponding step may be set or adjusted according to actual requirements, and is not limited and described in detail in this embodiment.
In step 2, performing mean value statistics on the output power strategies of the N operation periods in step 1 to obtain an initial output power strategy of the current operation period, specifically:
step 2.1, carrying out mean value statistics on the output power strategies of N operation periods in the step 1 to obtain a mean value statistical result;
and 2.2, increasing the control lead on the basis of the average value statistical result to obtain an initial output power strategy of the current operation period.
In step 2.1, the process of mean value statistics is divided into two steps, the first step is mean value statistics in the output power strategy, and the second step is mean value statistics between the output power strategies.
Although there is a difference in the output power at each moment of the operating cycle in an output power strategy, it must fluctuate over time periods above and below a certain value, for example in a school classroom toilet application scenario: the toilet is in a low-frequency use state in the class time period, the odor concentration is low, and the output power of the deodorization device fluctuates up and down at a low basic value in the class time period; the toilet is in a high-frequency use state in a class time period, the odor concentration is high, and the output power of the deodorization device fluctuates up and down at a high basic value in the class time period; the toilet is in a medium-frequency use state in the lunch break or lunch time period, the odor concentration is a medium basic value, and the output power of the deodorization device fluctuates up and down at a medium value in the time period. Therefore, firstly, the average value statistics is carried out once in the output power strategy, one operation cycle is divided into a plurality of time periods, and the basic value in each time period is used as the average value statistics result of the time period. The time interval division of different operation cycles needs to be kept consistent, so that mean value statistics among output power strategies in the second step is facilitated, namely, basic values of the N operation cycles in the same time intervals are averaged, and finally the mean value statistical result in the step 2.1 is obtained, wherein the specific structure of the mean value statistical result is also time intervals which are continuous in time, and each time interval has one basic value of output power.
In step 2.2, the control lead is increased on the basis of the mean value statistical result, specifically: and in the average value statistical result, for a time period when the basic value of the output power exceeds the threshold value, advancing the starting time of the time period by a control lead, wherein the control lead is 3-5 minutes, namely, the deodorization device is adjusted to the output power corresponding to the average value statistical result 3-5 minutes in advance. For example, in the toilet application scenario of school teaching building, 8 o 'clock to 8 o' clock 15 is the time of a class, the average statistical result has a period of time from 8 o 'clock to 8 o' clock 15, the output power of the period of time has a base value of a, and a is greater than the threshold, so that the period of time is modified from 8 o 'clock to 8 o' clock 15 to 7 o 'clock 55 to 8 o' clock 15, ensuring that the power output of the deodorizing device is increased before the class, thereby improving the user experience.
In this embodiment, one operation cycle of the deodorization apparatus is one day, that is, the output power strategy of the deodorization apparatus is designed according to the day.
The control method is further described below with reference to an example of a school scenario.
In the toilet application scene of the school teaching building, the scene during school is characterized in that: the toilet is rarely used before 7 am, the use frequency between 7 am and 8 am is increased, the toilet is hardly used in 45 minutes in a classroom after 8 am, and the toilet is intensively used in 10 minutes in the classroom. Noon is noon time, and the frequency of using the toilet is moderate. In the afternoon, similar to the morning situation, 45-minute toilets in the classroom are less used, and 10-minute toilets in the classroom are more used. For the night, part of schools do not have the study of the night, but the teacher does not work, so the toilet is used for a low frequency time.
The deodorization device in this embodiment operates according to an initial setting mode after installation, meets the deodorization requirement of the above-mentioned scene by controlling the output power, and stores and records the actual output power every day. And carrying out statistical analysis on the recorded output power, identifying the output power characteristics of each time period, and finishing the learning process of the working mode. Controlling the output power of the device according to the learned working mode, and gradually perfecting a power output mode by combining a closed-loop regulation process; in order to improve user experience, the control lead is added into the power output mode after learning, so that the power output is ensured to be improved before the actual power is increased, and the power output mode is further improved. And finally, outputting the deodorization power according to a designed working mode, and combining with closed-loop control to iteratively correct the working mode on line, wherein the learning process of the power output strategy is shown as the figure 2.
The embodiment also discloses a toilet deodorization self-adaptive control system which specifically comprises a strategy storage module, a mean value statistical module, a concentration acquisition module and an operation control module. The strategy storage module is used for storing an output power strategy of the historical operating period of the deodorization device; the average value counting module is used for carrying out average value counting on the output power strategies of the storage deodorization device in N operation periods, and outputting the initial output power strategy of the current operation period after increasing the control lead on the basis of the average value counting result; the concentration acquisition module is used for acquiring the odor concentration of the environment where the deodorization device is located; the operation control module is used for operating the deodorizing device according to an initial output power strategy in the current operation period, and finely adjusting the actual output power of the deodorizing device based on the odor concentration of the environment where the deodorizing device is located on the basis of the initial output power strategy in the operation process of the deodorizing device.
