It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein.

In the related art, a technical scheme for feeding back weather parameters to an air conditioner in real time by using a Data Transmission Unit (DTU) based on a wireless Internet of things card exists. For example, real-time weather parameter feedback to an appliance (e.g., a commercial air conditioner) can be achieved based on the wireless internet of things card. However, the traffic cost of the internet of things is far higher than that of WiFi at home, and how to reduce the device cost and the traffic cost as much as possible under the condition of ensuring the reliable weather parameters is also an urgent problem to be solved.
As shown in fig. 2, taking an air conditioning unit as an example, the air conditioning wireless weather acquisition system includes two major parts, a local weather application system and a remote weather service system. The local weather application system comprises a weather service unit, an air conditioning unit and a related sensing control system thereof. Based on cost consideration, the weather service unit is not provided with a GPS positioning module, and the positioning adopts the base station positioning of the Internet of things. The air conditioning unit is provided with a sensor for acquiring external environment parameters in real time, for example, the sensor comprises a temperature sensor, a humidity sensor and/or a wind speed sensor, and can detect the ambient temperature, the humidity and/or the wind speed. The remote weather service system comprises a remote server communicated with a weather service unit, an Internet of things network card operator information interface and a weather service data interface, wherein the operator information interface is mainly used for acquiring the information of the Internet of things network card, and the weather service data interface is used for inquiring the latest weather parameters.
The invention provides a weather information acquisition method based on an electric appliance. The method may be implemented on an appliance. For example, may be implemented as a weather service unit on an appliance that may communicate with a controller of the appliance.
Fig. 1 is a method schematic diagram of an embodiment of an appliance-based weather information acquisition method provided by the present invention.
As shown in fig. 1, according to an embodiment of the present invention, the method for acquiring an appliance-based weather bearing parameter at least includes step S110, step S120, and step S130.
And step S110, acquiring the Internet of things card information of the electric appliance.
The internet of things card is similar to a mobile phone SIM card, is a special SIM card proposed by operators (such as mobile, Unicom and telecommunication companies) aiming at the industrial application field, and can carry out GPRS wireless data transmission through the internet of things card to realize remote control. The information of the internet of things card includes, for example: at least one of ICCID, IMEI and ISMI.
Step S120, the Internet of things card information is sent to a remote server so as to request the remote server to inquire weather parameters of the position of the electric appliance according to the Internet of things card information.
And step S130, receiving the weather parameters of the position of the electric appliance returned by the remote server.
Specifically, the information of the Internet of things card of the electric appliance is used as a parameter to be sent to a remote server, the server is requested to inquire weather parameters of the position of the electric appliance, the remote server obtains the position information of the position of the electric appliance according to the information of the Internet of things card, and obtains the weather parameters of the position of the electric appliance from the weather server according to the position information. More specifically, the remote server identifies a corresponding Internet of things operator according to the Internet of things card information, acquires position information of the position of the electrical appliance through an information interface of the corresponding Internet of things operator, acquires weather parameters of the position of the electrical appliance from a weather server according to the position information, and returns the weather parameters. And receiving the weather parameters of the position of the electric appliance returned by the remote server, so that the electric appliance can be controlled according to the weather parameters of the position. For example, the electric appliance is an air conditioner, and the operation of the air conditioner can be controlled according to weather parameters of the position.
The weather parameters specifically include: weather parameters at the current time and weather parameters in the future, for example, weather parameters every preset time in the future. For example, the weather parameters returned by the remote server include current real-time weather information and weather forecast information for each hour of the next several hours.
Optionally, the internet of things card information is sent to a remote server every preset time to request the remote server to query weather parameters of the position of the electrical appliance according to the internet of things card information. For example, to save traffic, weather parameters are requested at a certain frequency, for example, once in 1 hour.
Optionally, the appliance may actively obtain weather parameters of the location. For example, when the electric appliance needs to acquire the weather parameters, the electric appliance sends a request to the weather service unit to actively acquire the weather parameters of the position.
In a specific embodiment, when a request for actively acquiring the weather parameters of the position sent by the controller of the electric appliance is received, the weather parameters of the position of the electric appliance at the time closest to the request time are returned to the controller of the electric appliance. For example, the weather service unit has queried 13: 00. 14:00, 15: and 00, if the weather parameter of the position where the electric appliance requests at 13:08, returning to 13:00, and if the unit requests at 13:45, returning to 14: 00.
In another specific implementation, when a request sent by a controller of the electrical appliance to actively acquire weather parameters of a location is received, data of time nearest to the request time is returned for the weather parameters which cannot be calculated, and for the weather parameters which can be calculated, the weather parameters at the request time and the weather parameters at the third future preset time are interpolated according to the time difference between the request time and the time at which the weather parameters are acquired last time, so as to obtain the weather parameters at the request time.
Specifically, the weather parameter that cannot be calculated is a weather parameter that is not represented by a numerical value, such as a weather condition, and is generally represented by sunny, light rain, heavy rain, and the like. And returning the weather parameter value or the weather parameter predicted value of the time nearest to the request time for the weather parameter which cannot be calculated. That is, the weather parameter value or the weather parameter predicted value at the time closest to the current request time is returned. For example, 13: 00. 14:00, 15: the predicted value of the weather parameter of 00 hour is returned to 13:00 weather condition if the electric appliance (such as an air conditioning unit) requests the weather condition at 13:08, and is returned to 14:00 weather condition if the unit requests the weather condition at 13: 45.
For the calculable weather parameters, namely parameters which can be represented by numerical values, such as temperature, air pressure, humidity and the like, the weather parameters at the requested time are calculated by using an interpolation method and returned to the electric appliances (such as an air conditioning unit). According to the ratio (i.e. the time ratio) of the time difference between the request time and the time for obtaining the weather parameters last time (less than 1 hour) to the time interval for obtaining the weather parameters, the calculation method is as follows: time difference (unit min)/time interval for obtaining weather parameters (for example, 60min), if the unit requests weather conditions at 13:08, the last time base point is 13:00, the ratio is (13:08-13:00)/60 is 8/60, and the weather parameters at the requested time and the weather parameters at the future preset time (for example, 1 hour in the future) are interpolated according to a set interpolation method to obtain the weather parameters at the requested time.
Taking linear interpolation as an example, w represents weather parameters, t represents time, and wiDay representing request timeValue of gas parameter, w1Weather parameter value, w, representing a preset time in the future (e.g. 1 hour in the future)0Representing the current weather parameter value, tiIndicates the time of request, t0Representing the last time the weather parameter was acquired, the weather parameter value for the requested time is available:
since the position of the operator needs to be determined before the weather parameter is acquired, in the related technology, the operator is requested to inquire the geographical position of the operator, and then the position information is used as the parameter and sent to the remote server to request the weather parameter from the remote server. This means that two data requests need to be made each time weather parameters are requested. According to the embodiment of the invention, two requests are simplified into one request, so that the flow cost can be saved.
Fig. 3 is a schematic flow chart of acquiring weather parameters according to an embodiment of the invention.
As shown in fig. 3, taking an air conditioner as an example, a weather service unit starts to work to acquire internet of things card information of the air conditioner, the weather service unit sends the internet of things card information as a parameter to a remote server and requests a weather parameter, the remote server receives the request and identifies a corresponding internet of things card operator according to the internet of things card information, acquires location information of the weather service unit by calling an operator information interface, calls a weather service data interface according to the location information to acquire the weather parameter, then returns the weather parameter to the weather service unit, the weather service unit forwards the weather parameter to an air conditioning unit, and the air conditioning unit processes related logic according to the weather parameter.
The weather parameters returned by the remote server comprise current weather information and weather parameters within a first preset time length in the future (such as weather forecast data within a plurality of hours). In order to save traffic, the weather service unit requests the weather parameters once every preset time according to a set frequency, for example, once every hour. Under the condition that the air conditioning unit actively requests weather parameters from the weather service unit, returning parameter values at the time close to the current request time for the non-calculable parameters; and for the calculable parameters, returning the weather parameters to the unit by using an interpolation method, and interpolating the weather parameters at the request time and the weather parameters at 1 hour (third preset time) in the future according to the set interpolation method according to the proportion of the time difference (less than 1 hour) between the request time and the time of obtaining the weather parameters at the last time to obtain the weather parameter values at the request time.
In order to further save flow and improve weather service accuracy, after a weather parameter of a position is requested, a comparison is carried out according to a current environment parameter and a future weather parameter predicted value, a deviation coefficient is determined according to a difference value between the current environment parameter and the future weather parameter predicted value and a preset weight coefficient, and according to the magnitude relation between the deviation coefficient and a preset frequency adding threshold or a preset skipping threshold, the frequency of requesting the weather parameter from the remote server is determined to be increased and/or the frequency of requesting the weather parameter from the remote server is determined to be reduced.
The deviation coefficient represents the difference between the predicted value and the actual value, the larger the deviation coefficient is, the larger the difference between the predicted value and the actual value is, the more inaccurate the predicted result is, and otherwise, the more accurate the predicted result is. The frequency adding threshold value is that when the deviation coefficient is larger than a certain value, the result of the current cache prediction is deemed to be completely untrustworthy, and the weather parameter prediction value needs to be requested again. The skip threshold is a value below which the cached prediction result is deemed reliable and does not require data retrieval. The future weather parameter predicted value comprises a weather parameter of each preset time in the future.
When the deviation coefficient is larger than the preset frequency adding threshold value, adding a request before the next weather parameter request; and when the deviation coefficient is smaller than the preset skipping threshold value, reducing one request, and taking the weather parameter predicted value corresponding to the next weather parameter request time in the future weather parameter predicted values as the weather parameter of the next weather parameter request time.
Fig. 4 shows a flow chart for adaptively adjusting the frequency of a weather request. As shown in fig. 4, in order to further save traffic and improve the accuracy of weather service, after a weather parameter is requested, the parameter data of the current environment is compared with a future predicted value, and a deviation coefficient is calculated after synthesis according to a difference value, a weight coefficient and the like, for example, a skipping threshold value and a frequency-adding threshold value are recorded by a weather service unit, for 1 hour in the future, when the deviation coefficient is greater than the frequency-adding threshold value, it indicates that the weather changes violently within 1 hour in the future, and in order to improve the weather response accuracy, a weather request needs to be added; when the deviation coefficient is less than or equal to the frequency-adding threshold and greater than or equal to the skipping threshold, according to the normal frequency request, when the deviation coefficient is less than the skipping threshold, it indicates that the weather change is not obvious, in order to save traffic, one weather request can be reduced, the weather parameter predicted value in the future of 1 hour is directly used as the weather parameter current value in the next request time, and then the deviation coefficients in the future of 2 hours and 3 hours are continuously calculated, so that the deviation coefficients in the future of 2 hours and 3 hours can be continuously compared, which can be specifically shown in fig. 4. To ensure the accuracy of the weather service, it may be set to reduce the number of weather requests, for example, at most 3 weather parameter requests may be skipped.
The deviation factor is calculated based on at least one weather parameter. Optionally, the at least one weather parameter comprises: at least one of ambient temperature, humidity, barometric pressure, and wind speed.
For example, to facilitate the deep understanding of the deviation coefficient, the four parameters of the ambient temperature, the humidity, the air pressure and the wind speed are simplified, and the calculation method is as follows:
where θ is a deviation coefficient, Δ T represents a temperature difference, CTRepresenting the temperature accuracy range constant, ωTRepresenting the weight corresponding to the temperature; Δ H represents the humidity difference, CHRepresenting the humidity accuracy range constant, ωHRepresenting the weight corresponding to the temperature; Δ P represents a pressure difference, CPRepresenting the constant, ω, of the accuracy range of the air pressurePRepresenting the weight corresponding to the air pressure; Δ W represents the wind speed difference, CWRepresenting wind speed accuracy range constant, ωWRepresenting the weight corresponding to the wind speed.
Assuming that the skip threshold is 10 and the addition threshold is 100, if the value of the deviation coefficient from the future 1 hour is calculated to be 200 at a time, 200>100, this time indicates that a weather request needs to be added in the half hour in the future; if the deviation coefficient values calculated at a certain time and 1 hour, 2 hours and 3 hours in the future are 5,6 and 12 respectively, it can be known from fig. 3 that 2 weather requests can be skipped, and the next weather parameter will be requested after three hours.
The invention also provides a weather information acquisition device based on the electric appliance. The device may be implemented on an appliance. For example, may be implemented as a weather service unit on an appliance that may communicate with a controller of the appliance.
Fig. 5 is a block diagram of an embodiment of an apparatus for acquiring weather information based on an electrical appliance according to the present invention. As shown in fig. 5, the appliance-based weather information acquiring apparatus 100 includes an acquiring unit 110, a requesting unit 120, and a first receiving unit 130.
The obtaining unit 110 is configured to obtain internet of things card information of the electrical appliance.
The internet of things card is similar to a mobile phone SIM card, is a special SIM card proposed by operators (such as mobile, Unicom and telecommunication companies) aiming at the industrial application field, and can carry out GPRS wireless data transmission through the internet of things card to realize remote control. The information of the internet of things card includes, for example: at least one of ICCID, IMEI and ISMI.
The request unit 120 is configured to send the internet of things card information to a remote server, so as to request the remote server to query weather parameters of the location of the electrical appliance according to the internet of things card information. The first receiving unit 130 is configured to receive the weather parameter of the location where the electrical appliance is located, which is returned by the remote server.
Specifically, the information of the Internet of things card of the electric appliance is used as a parameter to be sent to a remote server, the server is requested to inquire weather parameters of the position of the electric appliance, the remote server obtains the position information of the position of the electric appliance according to the information of the Internet of things card, and obtains the weather parameters of the position of the electric appliance from the weather server according to the position information. More specifically, the remote server identifies a corresponding Internet of things operator according to the Internet of things card information, acquires position information of the position of the electrical appliance through an information interface of the corresponding Internet of things operator, acquires weather parameters of the position of the electrical appliance from a weather server according to the position information, and returns the weather parameters. And receiving the weather parameters of the position of the electric appliance returned by the remote server, so that the electric appliance can be controlled according to the weather parameters of the position. For example, the electric appliance is an air conditioner, and the operation of the air conditioner can be controlled according to weather parameters of the position.
The weather parameters specifically include: weather parameters at the current time and weather parameters in the future, for example, weather parameters every preset time in the future. For example, the weather parameters returned by the remote server include current real-time weather information and weather forecast information for each hour of the next several hours.
Optionally, the requesting unit 120 sends the internet of things card information to a remote server every preset time interval, so as to request the remote server to query weather parameters of the location of the electrical appliance according to the internet of things card information. For example, to save traffic, weather parameters are requested at a certain frequency, for example, once in 1 hour.
Optionally, the appliance may actively obtain weather parameters of the location. For example, when the electric appliance needs to acquire the weather parameters, the electric appliance sends a request to the weather service unit to actively acquire the weather parameters of the position.
Optionally, the apparatus 100 further comprises a second receiving unit and a returning unit (not shown). The second receiving unit is used for receiving a request that the electrical appliance actively acquires the weather parameters of the position; the return unit is used for returning the weather parameters of the position of the electric appliance at the time closest to the request time to the electric appliance when the second receiving unit receives the request of the electric appliance for actively acquiring the weather parameters of the position of the electric appliance; or for the weather parameters which can not be calculated, returning the data of the time nearest to the request time, for the weather parameters which can be calculated, interpolating the weather parameters at the request time and the weather parameters at the future preset time according to the time difference between the request time and the time of obtaining the weather parameters last time to obtain the weather parameter values at the request time, and returning the weather parameter values to the electric appliance.
In a specific embodiment, when the second receiving unit receives a request for actively acquiring the weather parameter of the location sent by the controller of the electrical appliance, the returning unit returns the weather parameter of the location of the electrical appliance at the time closest to the request time to the controller of the electrical appliance. For example, the weather service unit has queried 13: 00. 14:00, 15: and 00, if the weather parameter of the position where the electric appliance requests at 13:08, returning to 13:00, and if the unit requests at 13:45, returning to 14: 00.
In another specific embodiment, when the second receiving unit receives a request for actively acquiring the weather parameter of the location sent by the controller of the electrical appliance, the returning unit returns data of the time nearest to the request time for the weather parameter that cannot be calculated, and interpolates the weather parameter of the request time and the weather parameter of the third preset time in the future according to the time difference between the request time and the time for acquiring the weather parameter last time for the weather parameter that can be calculated, so as to obtain the weather parameter of the request time.
Specifically, the weather parameter that cannot be calculated is a weather parameter that is not represented by a numerical value, such as a weather condition, and is generally represented by sunny, light rain, heavy rain, and the like. And returning the weather parameter value or the weather parameter predicted value of the time nearest to the request time for the weather parameter which cannot be calculated. That is, the weather parameter value or the weather parameter predicted value at the time closest to the current request time is returned. For example, 13: 00. 14:00, 15: the predicted value of the weather parameter of 00 hour is returned to 13:00 weather condition if the electric appliance (such as an air conditioning unit) requests the weather condition at 13:08, and is returned to 14:00 weather condition if the unit requests the weather condition at 13: 45.
For the calculable weather parameters, namely parameters which can be represented by numerical values, such as temperature, air pressure, humidity and the like, the weather parameters at the requested time are calculated by using an interpolation method and returned to the electric appliances (such as an air conditioning unit). According to the ratio (i.e. the time ratio) of the time difference between the request time and the time for obtaining the weather parameters last time (less than 1 hour) to the time interval for obtaining the weather parameters, the calculation method is that the time difference (unit min)/the time interval for obtaining the weather parameters (e.g. 60min), if the unit requests the weather conditions at 13:08, the last time base point is 13:00, the ratio is (13:08-13:00)/60 is 8/60), and the weather parameters at the request time and the weather parameters at the preset time in the future (e.g. 1 hour in the future) are interpolated according to the set interpolation method to obtain the weather parameters at the request time.
Taking linear interpolation as an example, w represents a weather parameter, t represents time, wi represents a weather parameter value of a requested time, w1Weather parameter value, w, representing a preset time in the future (e.g. 1 hour in the future)0Representing the current weather parameter value, tiIndicates the time of request, t0Representing the last time the weather parameter was acquired, the weather parameter value for the requested time is available:
since the position of the operator needs to be determined before the weather parameter is acquired, in the related technology, the operator is requested to inquire the geographical position of the operator, and then the position information is used as the parameter and sent to the remote server to request the weather parameter from the remote server. This means that two data requests need to be made each time weather parameters are requested. According to the embodiment of the invention, two requests are simplified into one request, so that the flow cost can be saved.
Optionally, the apparatus 100 further comprises a determining unit (not shown). The determining unit is used for comparing the current environment parameter with a future weather parameter predicted value after requesting the weather parameter of the position, determining a deviation coefficient according to the difference value between the current environment parameter and the future weather parameter predicted value and a preset weight coefficient, and determining to increase the frequency of requesting the weather parameter from the remote server and/or decrease the frequency of requesting the weather parameter from the remote server according to the magnitude relation between the deviation coefficient and a preset frequency adding threshold or a preset skipping threshold.
The deviation coefficient represents the difference between the predicted value and the actual value, the larger the deviation coefficient is, the larger the difference between the predicted value and the actual value is, the more inaccurate the predicted result is, and otherwise, the more accurate the predicted result is. The frequency adding threshold value is that when the deviation coefficient is larger than a certain value, the result of the current cache prediction is deemed to be completely untrustworthy, and the weather parameter prediction value needs to be requested again. The skip threshold is a value below which the cached prediction result is deemed reliable and does not require data retrieval. The future weather parameter predicted value comprises a weather parameter of each preset time in the future.
When the deviation coefficient is larger than the preset frequency adding threshold value, adding a request before the next weather parameter request; and when the deviation coefficient is smaller than the preset skipping threshold value, reducing one request, and taking the weather parameter predicted value corresponding to the next weather parameter request time in the future weather parameter predicted values as the weather parameter of the next weather parameter request time.
The deviation factor is calculated based on at least one weather parameter. Optionally, the at least one weather parameter comprises: at least one of ambient temperature, humidity, barometric pressure, and wind speed.
For example, to facilitate the deep understanding of the deviation coefficient, the four parameters of the ambient temperature, the humidity, the air pressure and the wind speed are simplified, and the calculation method is as follows:
where θ is a deviation coefficient, Δ T represents a temperature difference, CTRepresenting the temperature accuracy range constant, ωTRepresenting the weight corresponding to the temperature; Δ H represents the humidity difference, CHRepresenting the humidity accuracy range constant, ωHIndicating temperature correspondenceThe weight of (c); Δ P represents a pressure difference, CPRepresenting the constant, ω, of the accuracy range of the air pressurePRepresenting the weight corresponding to the air pressure; Δ W represents the wind speed difference, CWRepresenting wind speed accuracy range constant, ωWRepresenting the weight corresponding to the wind speed.
Assuming that the skip threshold is 10 and the addition threshold is 100, if the value of the deviation coefficient from the future 1 hour is calculated to be 200 at a time, 200>100, this time indicates that a weather request needs to be added in the half hour in the future; if the deviation coefficient values calculated at a certain time and 1 hour, 2 hours and 3 hours in the future are 5,6 and 12 respectively, it can be known from fig. 3 that 2 weather requests can be skipped, and the next weather parameter will be requested after three hours.
