The following explains an application scenario of the embodiment of the present invention:
fig. 1 is an application scenario diagram of a zero-cold water control method for a water heater according to an embodiment of the present invention, as shown in fig. 1, in this embodiment, an air-powered water heater is taken as an execution subject of the zero-cold water control method for the water heater, specifically, the air-powered water heater is disposed outdoors, a water consumption point is disposed indoors, the air-powered water heater is communicated with the water consumption point through a circulation water path, the air-powered water heater circulates and heats water in the circulation water path through a water outlet and a water return port, so that the water temperature in the circulation water path is always kept at a preset temperature value, after the water consumption point is turned on, hot water in the circulation water path directly flows out from the water consumption point, zero-cold water supply is achieved, and there are many specific application scenarios for the zero-cold water supply, such as a bath water scenario, a hand washing water scenario, and the zero-cold water supply achieved by the water heater and the circulation water path, so that a user does not need to drain water and wait for a long time, the water resource is saved, and the user experience is improved.
In the prior art, in consideration of safety and convenience, the intelligent water heater is generally installed in places such as kitchens and bathrooms and balconies, a water tank and a water outlet of the water heater are longer than a water pipeline at a water end, cold water is easily generated in a circulating water path, and water in the circulating water path needs to be circularly heated for realizing zero-cold-water supply. However, in the actual use process, the time periods when the user has water demand are not uniformly distributed, for example, when the user goes out in a working day, and after a rest at night, the user does not have the demand for using hot water, but in the prior art, the water in the circulating water path is still circularly heated, so that the energy waste is caused, and the use cost of the user is increased.

In a possible implementation manner, the positioning unit is a terminal device with a positioning function, such as a smart phone, and more specifically, for example, in an outdoor scene, a user carries the smart phone at any time at preset time intervals, current positioning information, such as GPS data and current time, is sent to the smart water heater through the server, and the smart water heater determines, according to the positioning information, an area identifier and a trigger time corresponding to a location of the user, so as to determine location information of the user.
In another possible implementation, the positioning unit is a sensing device or apparatus for sensing an external environment, i.e. a sensor unit. And if the sensor unit detects that the user passes through the target area, acquiring identification information and trigger time of the sensor, wherein the identification information of the sensor corresponds to the area identification one by one, and generating position information of each user according to each identification information and each trigger time.
Specifically, the intelligent water heater acquires sensor information sent by the sensor unit in real time, and judges whether a user passes through a target area according to the sensor information. In one possible implementation, the sensor unit is, for example, an infrared sensor, the target area is, for example, a kitchen, and the infrared sensor is arranged at an entrance of the kitchen, which detects an entrance area of the kitchen. When the user does not pass through the detection area of the infrared sensor, the infrared sensor outputs a low level, and when the user passes through the detection area of the infrared sensor, the infrared sensor outputs a high level, and the intelligent water heater judges whether the user passes through a target area corresponding to the sensor according to the high and low levels sent by the infrared sensor, namely judges whether the user enters the kitchen or leaves the kitchen. The infrared sensor may also be placed in other locations to inspect different target areas, such as toilets, living rooms, etc., as may be particularly desired. In another possible implementation manner, the sensor unit is, for example, a camera for image acquisition, acquires image information of user movement and sends the image information to the intelligent water heater, and after the image information is identified by the intelligent water heater, whether the user passes through a target area is determined. It is understood that the sensor unit may also have other implementation forms, such as a laser radar, and the like, which are not described herein in detail and may be specifically configured as required.
Further, after detecting that the user passes through the target area, the identification information of the sensor unit and the corresponding trigger time, that is, the time when the user passes through the target area, are acquired. Fig. 4 is a schematic diagram of detecting a movement track of a user according to an embodiment of the present invention, as shown in fig. 4, in an indoor activity scene, an intelligent water heater 400 is disposed outdoors, the indoor environment includes five areas a to E, when the user moves from the area a to the areas B and C in sequence, by disposing an infrared sensor 401, when the user passes through the areas a, B and C, the infrared sensor transmits sensing data to the intelligent water heater 402, and the intelligent water heater 402 determines identification information of the infrared sensor 401 corresponding to the areas a, B and C and trigger time according to level information, and generates user location information corresponding to the areas a, B and C, respectively.
It can be understood that, when the intelligent water heater is applied to an outdoor activity scene, the intelligent water heater generates user location information capable of representing user location and corresponding time by receiving location information sent by a terminal device of a user, and the process is not described herein again.
Step S203, generating moving time sequence information according to each trigger time and the corresponding area identification; the moving time sequence information is used for representing the time of the user reaching the target area corresponding to each area identifier and the staying time of the user in the target area corresponding to each area identifier.
Illustratively, after the area identifier and the trigger time are obtained through the user position information, according to the time sequence relationship of the trigger time and the corresponding area identifier, the movement track of the user and the variation characteristic of the movement track in the time dimension can be determined, and more specifically, referring to the embodiment shown in fig. 4, for example, in the embodiment shown in fig. 4, through preset setting position information of the infrared sensor and identification information of the sensor, the area a is determined as the living room, the area B is a refrigerator placing area, the area C is the kitchen, and through the corresponding trigger time, level duration and other information, the movement track of the user passing through the living room, the refrigerator and the kitchen in sequence and the duration of the user staying in the refrigerator position and the kitchen are determined. Fig. 5 is a schematic diagram of movement timing information provided by an embodiment of the present disclosure, and referring to fig. 4, in the process that a user moves from an area a to an area C in sequence, the movement timing information shown in fig. 5 may be determined according to a trigger time and a corresponding area identifier, and exemplarily, the movement timing information represents that the user leaves a living room area at 11 points 30 minutes and 10 seconds, leaves the refrigerator area at 11 points 30 minutes and 15 seconds, stays for 30 seconds, leaves the refrigerator area at 11 points 30 minutes and 45 seconds, enters a kitchen at 11 points 30 minutes and 46 seconds, leaves the kitchen area at 11 points 30 minutes and 56 seconds after staying for 10 seconds, enters the refrigerator area at 11 points 30 minutes and 57 seconds, and stays for 20 seconds.
More specifically, the movement timing information may be implemented in a table, and referring to table 1, table 1 is a data structure diagram of the movement timing information provided in the embodiment of the present invention, and each action is an area entry time, an area exit time, and an area identifier corresponding to user location information. The area entry time and the area exit time are determined by the trigger time, and the process is not described herein.
TABLE 1
| Time of zone entry | Time of departure of area | Region identification |
| 11:20:00 | 11:30:10 | A |
| 11:30:15 | 11:30:45 | B |
| 11:30:46 | 11:30:56 | C |
| 11:30:57 | 11:31:17 | B |
| … | … | … |
In another possible implementation manner, after determining the user location information according to the location of the user uploaded by the terminal device in an outdoor activity scene, the same or similar movement timing sequence information as that in the embodiment shown in fig. 5 and table 1 may also be generated according to the trigger time and the corresponding area identifier in the location information, which has a similar implementation principle and is not described herein again.
And step S204, determining the water use scene information according to the movement time sequence information.
For example, after the movement time series information is determined, since the movement time series information can represent the behavior characteristics of the user, for example, in an indoor activity scene, according to the movement time series information corresponding to the movement behavior of the user in each indoor area, it may be determined whether the user currently has a specific water demand for bathing, cooking, and the like, so as to determine the user scene information. More specifically, for example, from the movement timing information as shown in fig. 5, it is possible to predict the water usage scenario in which the user is currently cooking, and thus determine that the corresponding water usage scenario information corresponds to "water for cooking".
Furthermore, the concrete implementation mode of the water usage scenario information is determined according to the movement time sequence information, and the purpose of determining the water usage scenario information according to the neural network model can be achieved by acquiring a training set comprising the movement time sequence information and corresponding water usage data in advance and performing neural network model training based on the training set, so that the neural network model capable of outputting the water usage scenario information according to the movement time sequence information is obtained. The process of training and using models is prior art in the field and will not be described herein.
