Embodiment
The core of the application is to provide a kind of temperature control method of water and device, so as to according to different environmental condition and use
Family, the Intelligent Dynamic regulation to water temperature is realized, improves Consumer's Experience.
In order to more clearly and completely be described to the technical scheme in the embodiment of the present application, below in conjunction with this Shen
Accompanying drawing that please be in embodiment, the technical scheme in the embodiment of the present application is introduced.Obviously, described embodiment is only
Some embodiments of the present application, rather than whole embodiments.Based on the embodiment in the application, those of ordinary skill in the art
The every other embodiment obtained under the premise of creative work is not made, belong to the scope of the application protection.
Fig. 1 is refer to, a kind of flow chart for temperature control method of water that Fig. 1 is provided by the embodiment of the present application, is mainly included
Following steps：
Step 1：Obtain ambient parameter and User Identity.
Because under different environmental conditions, such as temperature etc., same user can substantially to the demand for control of water temperature
Difference；Also, different user also differs under same environmental condition to the demand for control of water temperature, therefore, acquisition can be passed through
Ambient parameter and User Identity, the difference that water temperature is carried out to varying environment condition, different user control.
Step 2：According to ambient parameter and User Identity, pass through neural computing target temperature.
The problem of for multi input, single output, want to solve the specific function between input and output by mathematical method
Relation is extremely difficult.And neutral net can be obtained with ideal fit effect after training according to input parameter
Output result.Here, the input parameter of neutral net is exactly the ambient parameter and user identity described in step 1 in the application
Mark, output result is exactly coolant controlled target temperature.Certainly, in order to obtain preferable fitting effect, neutral net makes
It is trained with preceding needs according to substantial amounts of sample data, substantial amounts of sample data mentioned here can make from the history of user
Obtained with record data.
Step 3：According to target temperature, water temperature is adjusted by pid control algorithm.
PID control is control method most basic in automation field and conventional.Water temperature is calculated when passing through step 2
After the target temperature of control process, you can water temperature is adjusted by pid control algorithm, i.e. obtain temperature sensor and adopt
The actual water temperature collected, the difference of actual water temperature and target temperature is subjected to PID arithmetic, according to computing output quantity regulation water heater
The aperture of hot water valve and cold valves, so that actual water temperature reaches target temperature.
It can be seen that the temperature control method of water that the embodiment of the present application is provided, according to ambient parameter and User Identity, is utilized
Neural computing goes out dynamic target water temperature, so as to which actual water temperature is adjusted using pid control algorithm, reaches target

Section.
Important environmental factor of the mankind to temperature sensing is had influence in addition, ambient humidity is also another.Due to wet
Spend in big environment, the speed that human body perspires declines, therefore can think that comparison is hot under identical ambient air temperature, then can train
Neutral net exports relatively low target temperature at this moment.
In addition, because ambient air temperature throughout the year, among 24 hours one day and ambient humidity are different；And
And even if in the case when they are equal, the body temperature of user in itself is also not necessarily identical, for example, user just wake up morning
When body temperature to be typically less than the body temperature of noon on the same day.Therefore, area can be carried out with current time during water according to user
Do not control.Specifically, the current time can be as accurate as hour, the season information reflected so as to neutral net according to month
The conventional body temperature information of average environment temperature information and user in the period reflected with hour, to export corresponding mesh

Specifically, BP neural network in the training process, when the target output result in output result and training sample
When difference is more than certain threshold value, the weights of each layer neuron in BP neural network will be adjusted according to gradient descent method, until defeated
Go out result and meet certain required precision., can be in very high precision because BP neural network is after substantial amounts of training is passed through
In the range of be fitted arbitrary target function, therefore effectively can further improve the control accuracy to water temperature.
As a kind of preferred embodiment, according to target temperature, after water temperature is adjusted by pid control algorithm
Also include：
Obtain the evaluation information of user's input；
The weights of neutral net are adjusted according to evaluation information.
