Fig. 2 is a flow chart of an evaluation method of an energy saving effect of an air conditioner according to an embodiment of the disclosure. The evaluation method of the air conditioner energy saving effect of fig. 2 may be performed by the terminal device or the server of fig. 1. As shown in fig. 2, the method for evaluating the energy saving effect of the air conditioner includes:
s201, receiving a screening instruction and a screening condition;
s202, determining a reference day from an air-conditioning history database of a target air conditioner according to a screening instruction, and acquiring environmental parameters of the reference day from the air-conditioning history database, wherein the air-conditioning history database comprises a plurality of dates and daily environmental parameters;
s203, determining a target environmental parameter from an air conditioner historical database according to the environmental parameter of the reference day and the screening condition, and determining a similar day according to the target environmental parameter, wherein the target environmental parameter is the environmental parameter of the similar day;
s204, generating an energy-saving evaluation result of the target air conditioner based on the environmental parameter of the reference day and the target environmental parameter.
The reference day and the similar day are two dates, and the similar day can be multiple, so that the target environment parameters determined from the air conditioner history database can be multiple, and one similar day corresponds to one target environment parameter. The operation of the air conditioner is environment-dependent, so regarding the energy saving evaluation result of the target air conditioner, the environmental parameter of the reference day and the target environmental parameter should be considered. Environmental parameters, including: the indoor temperature parameter and humidity parameter, the outdoor temperature parameter and humidity parameter, because the indoor temperature and humidity are relatively constant, may be characterized as an average value over a period of time, and the indoor temperature parameter and humidity parameter may include a maximum value, a minimum value, and an average value because the outdoor temperature and humidity are relatively variable.
The energy saving evaluation result of the target air conditioner can be understood as evaluating the environmental parameters of the reference day by means of the environmental parameters of the similar day. For example, the reference day and the similar day are each a day of summer, and the environmental parameters of the similar day include: the indoor temperature is 22 degrees, the humidity is forty percent (the value of each environmental parameter can be a relative value, such as relative humidity, which is a term, not described here), the outdoor temperature is 30 degrees, and the humidity is twenty percent; environmental parameters for a reference day, including: the indoor temperature is 25 degrees, the humidity is sixty percent (the value of each environmental parameter may be a relative value, such as relative humidity, which is a term of art, not described herein), the outdoor temperature is 29 degrees, and the humidity is twenty percent. The outdoor temperature of the reference day is similar to that of the similar day, and the indoor environment parameters of the similar day are obviously more in line with the health of a human body, so that compared with the similar day, the target air conditioner of the reference day has a remarkable energy-saving effect, and the finally obtained energy-saving evaluation result is poor. The indoor environment parameters are related to the setting of the air conditioner by the user, the environment parameters of the reference day are evaluated by the environment parameters of the similar day, and the setting of the air conditioner by the user is compared for two times; the reference day is related to the screening instruction input by the user; the similar day is related to the screening conditions entered by the user. The above processes all involve the operation of the user, and the operation of the user certainly makes the user feel more comfortable, and the evaluation method of the air conditioner energy saving effect provided by the present disclosure gives consideration to the user experience.
According to the technical scheme provided by the embodiment of the disclosure: receiving a screening instruction and a screening condition; determining a reference day from an air-conditioning history database of a target air conditioner according to a screening instruction, and acquiring environmental parameters of the reference day from the air-conditioning history database, wherein the air-conditioning history database comprises a plurality of dates and daily environmental parameters; determining a target environmental parameter from an air conditioner historical database according to the environmental parameter of the reference day and the screening condition, and determining a similar day according to the target environmental parameter, wherein the target environmental parameter is the environmental parameter of the similar day; and generating an energy-saving evaluation result of the target air conditioner based on the environmental parameters of the reference day and the target environmental parameters. By adopting the technical means, the problem that the energy-saving effect of the air conditioner cannot be evaluated by the user in the prior art can be solved, and the evaluation method for the energy-saving effect of the air conditioner with the user experience is further provided.
After executing step S203, that is, after determining the target environmental parameter from the air conditioner history database according to the environmental parameter and the screening condition of the reference day, and determining the similar day according to the target environmental parameter, the method further includes: when the determined number of similar days is greater than the first preset threshold or less than the second preset threshold: updating screening conditions based on the determined number of similar days, a first preset threshold value and a second preset threshold value; and updating the target environment parameters and the similar days according to the updated screening instruction.
The method comprises the steps of evaluating the environmental parameters of a reference day by means of the environmental parameters of the similar day, specifically, the environmental parameters of the similar day and the outdoor environmental parameters of the reference day are close, then comparing the environmental parameters of the similar day and the indoor environmental parameters of the reference day, if the environmental parameters of the indoor environmental parameters of the reference day are obviously larger than the environmental parameters of the indoor environmental parameters of the similar day, the energy-saving evaluation result is that the energy-saving effect is not practical, and if the environmental parameters of the indoor environmental parameters of the reference day are obviously close to the environmental parameters of the indoor environmental parameters of the similar day, the energy-saving evaluation result is that the energy-saving effect is good. Based on this principle, the determined number of similar days should be within a certain range, and if the determined number of similar days is beyond, that is, when the determined number of similar days is greater than a first preset threshold or less than a second preset threshold, it is indicated that the screening condition is not appropriate, and the screening condition should be adjusted, and the screening condition may be an adjustment of environmental parameters of the reference day, for example, the screening condition includes that the target outdoor temperature may be adjusted by more or less than 3 degrees on the basis of the reference outdoor temperature. The target environmental parameter includes a target outdoor temperature. For example, the number of similar days is 10, the first preset threshold is 3, and the second preset threshold is 5, then the screening condition should be made more strict, for example, the original screening condition includes that the target outdoor temperature can be adjusted by more or less than 3 degrees based on the reference outdoor temperature, and then the target outdoor temperature can be adjusted by more or less than 2 degrees based on the reference outdoor temperature.
The method of updating the target environment parameters and the similar days according to the updated filtering instruction is the same as the previous embodiment.
In step S204, based on the environmental parameter of the reference day and the target environmental parameter, an energy saving evaluation result of the target air conditioner is generated, including: acquiring a first equipment parameter of a target air conditioner on a reference day and a second equipment parameter of the target air conditioner on a similar day; and generating an energy-saving evaluation result of the target air conditioner based on the first equipment parameter, the second equipment parameter, the environmental parameter of the reference day and the target environmental parameter.
The equipment parameters may represent the temperature, humidity, wind speed, etc. set on the air conditioner. The energy saving evaluation result of the target air conditioner is generated based on only the environmental parameter of the reference day and the target environmental parameter, and is not accurate because the equipment parameter of the air conditioner is not considered, and the equipment parameter of the air conditioner is directly related to the energy consumption. The embodiment of the disclosure considers the first equipment parameter and the second equipment parameter in generating the energy-saving evaluation result of the target air conditioner. For example, the environmental parameters of the reference day and the similar day are close, the wind speed in the first equipment parameter is in a mute mode, the second equipment parameter is in a strong mode, so that the energy-saving effect of the reference day is better, and the energy-saving evaluation result of the target air conditioner is that the energy saving is good.
After generating the energy-saving evaluation result of the target air conditioner based on the first equipment parameter, the second equipment parameter, the environmental parameter of the reference day and the target environmental parameter, the method further comprises: generating optimal equipment parameters of the target air conditioner based on the energy saving evaluation result, the first equipment parameters and the second equipment parameters; and controlling the target air conditioner according to the optimal equipment parameters.
For example, the environmental parameters of the reference day and the similar day are close, the wind speed in the first equipment parameter is a mute mode, the second equipment parameter is a powerful mode, the energy saving evaluation result of the target air conditioner is that the energy saving is good, the mute mode is a better choice, and if the environmental parameters corresponding to the reference day are close to each other on the A day, the optimal score parameter in the optimal equipment parameters on the A day is the mute mode.
After step S202 is performed, that is, after the reference day is determined from the air conditioning history database of the target air conditioner according to the screening instruction, the method further includes: acquiring minute-level environmental parameters of a reference day from an air conditioner historical database, wherein the environmental parameters comprise minute-level environmental parameters; determining a target minute-level environment parameter from an air conditioner historical database according to the minute-level environment parameter and the screening condition of the reference day, and determining a similar day according to the target minute-level environment parameter, wherein the target minute-level environment parameter is the minute-level environment parameter of the similar day; and generating a minute-level energy-saving evaluation result of the target air conditioner based on the minute-level environmental parameter of the reference day and the target minute-level environmental parameter, wherein the energy-saving evaluation result comprises a minute-level energy-saving evaluation result.
The minute-scale environmental parameter of the reference day is an environmental parameter over a period of time of the reference day, which may be greater than one minute and less than one hour in length. The hour-level environmental parameters and day-level environmental parameters are similar to the minute-level environmental parameters.
The embodiment of the disclosure and the following two embodiments provide energy-saving evaluation results with different levels, and can be applied to different scenes to improve the accuracy of the energy-saving evaluation results.
After step S202 is performed, that is, after the reference day is determined from the air conditioning history database of the target air conditioner according to the screening instruction, the method further includes: acquiring an hour-level environmental parameter of a reference day from an air conditioner historical database, wherein the environmental parameter comprises the hour-level environmental parameter; determining a target hour environmental parameter from an air conditioner historical database according to the hour environmental parameter and the screening condition of the reference day, and determining a similar day according to the target hour environmental parameter, wherein the target hour environmental parameter is the hour environmental parameter of the similar day; and generating an hour-level energy-saving evaluation result of the target air conditioner based on the hour-level environmental parameter and the target hour-level environmental parameter of the reference day, wherein the energy-saving evaluation result comprises an hour-level energy-saving evaluation result.
After step S202 is performed, that is, after the reference day is determined from the air conditioning history database of the target air conditioner according to the screening instruction, the method further includes: acquiring a day-level environmental parameter of a reference day from an air conditioner historical database, wherein the environmental parameter comprises a day-level environmental parameter; determining a target day-level environmental parameter from an air conditioner historical database according to the day-level environmental parameter of the reference day and the screening condition, and determining a similar day according to the target day-level environmental parameter, wherein the target day-level environmental parameter is the day-level environmental parameter of the similar day; and generating a daily energy-saving evaluation result of the target air conditioner based on the daily environmental parameter of the reference day and the target daily environmental parameter, wherein the energy-saving evaluation result comprises a daily energy-saving evaluation result.
Any combination of the above optional solutions may be adopted to form an optional embodiment of the present application, which is not described herein in detail.
