Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the drawings of the embodiments of the present invention. It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. And the embodiments and features of the embodiments may be combined with each other without conflict. All other embodiments, which can be derived by a person skilled in the art from the described embodiments of the invention without any inventive step, are within the scope of protection of the invention.
Unless defined otherwise, technical or scientific terms used herein shall have the ordinary meaning as understood by one of ordinary skill in the art to which this invention belongs. The use of "first," "second," and similar terms in the present application do not denote any order, quantity, or importance, but rather the terms are used to distinguish one element from another. The word "comprising" or "comprises", and the like, means that the element or item listed before the word covers the element or item listed after the word and its equivalents, but does not exclude other elements or items. The terms "connected" or "coupled" and the like are not restricted to physical or mechanical connections, but may include electrical connections, whether direct or indirect.
It should be noted that the sizes and shapes of the figures in the drawings are not to be considered true scale, but are merely intended to schematically illustrate the present invention. And the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout.
Generally, the air conditioning apparatus may include a floor heating air conditioner, a central air conditioner, and the like. For example, as shown in fig. 1, the floor heating air conditioner may include: the centralized control ware 014, outer machine 013 of air conditioner, indoor set 011 and ground heating coil 012 etc.. The outdoor unit 013 includes an outdoor unit 0131 and a water system (e.g., a water tank 0132 with a controller). The outdoor unit 0131 is connected with the water tank 0132 and is respectively connected with the indoor unit 011 and the floor heating coil 012 through the centralized controller 014, so that the function of heating the floor heating coil through the water system is achieved, and the water system adopts a circuit main board of the outdoor unit to supply power. However, when the outdoor unit is in a low temperature environment (e.g. below-4 °), if the outdoor unit is not powered on for a while, the water tank 0132 may be easily frozen or frozen, which may result in that the air conditioning equipment cannot be used normally, thereby reducing the user experience and increasing the use cost.
The embodiment of the invention provides an anti-freezing early warning method and system for an air conditioner external unit and a server, which are used for carrying out anti-freezing early warning on the air conditioner external unit.
As shown in fig. 1, the outdoor unit of the air conditioner may further include a data interaction module 0133, where the data interaction module is configured to send the report data every set report time. The data interaction module may be disposed in the outdoor unit, for example, the data interaction module is electrically connected to a circuit board of the outdoor unit, so as to supply power by using the circuit board.
And the data interaction module can collect the temperature, the working mode and the like of the outdoor unit to form reported data so as to send the reported data to the server. Illustratively, the data interaction module is configured to send the report data to the server at set report time intervals based on the NB-IOT technology. This can reduce costs.
Illustratively, the set reporting time may be set to 6h, 12h, 24h or 48 h. Of course, the set reporting time may be determined by design according to the requirements of the actual application, and is not limited herein.
In some examples, the data interaction module may interactively communicate with a corresponding application program (APP) in the mobile terminal through a server. For example, the APP may display some operation interfaces, and the user may log in an account bound to the data interaction module through the APP and control the data interaction module to acquire the reported data of the outdoor unit through corresponding function buttons in the operation interfaces.
In some examples, in order to improve the safety of the use of the air conditioner, each user can only log in the own account and only see the content in the own account, so as to protect the privacy safety of the user. Alternatively, the user may be required to enter personal basic information during the registration process when the user logs in for the first time. After the registration is finished and the user logs in later, the user logs in by means of fingerprint identification, account password, face identification and the like.
Illustratively, the user bound by the air conditioner external unit may be a user corresponding to an account bound with the data interaction module through APP login. In particular, the user bound with the air conditioner external unit may have a grade. For example, the users bound by the outdoor unit of the air conditioner may include an administrator and general users. The administrator is higher in level than the general user, and thus the general user can be managed by the administrator. For example, the floor heating air conditioner may be disposed in a household, and the user bound with the air conditioner external unit may be a member in the household. One user to which the air conditioner external unit is bound may be set as an administrator, and the administrator may be set as a home administrator. For example, if the user bound by the air conditioner external unit is 3 members of a family, 1 member of the 3 members may be set as a family administrator, and the rest members are common users. It should be noted that there may be only one family manager, so that common users can be managed in a unified manner. If the home administrator does not exist, the user can be selected as the home administrator when the user is registered, and if the user exists, the registered user is a common user. When logging in the account subsequently, the family administrator can change the account of the family administrator to a common user or transfer the family administrator to a certain common user so as to convert the common user into the family administrator and convert the original family administrator into the common user.
For example, when the administrator registers an account, the geographical location of the air conditioner external unit where the corresponding bound data interaction module is located may be set together to be stored in the account.
The embodiment of the invention provides an anti-freezing early warning method for an air conditioner outdoor unit, which comprises the following steps of:
s210, receiving reported data of an air conditioner external unit;
s220, when the reported data of the air conditioner external unit are not received within the preset time, determining the air conditioner external unit as an offline air conditioner external unit;
s230, determining air temperature value data in a future set time period corresponding to the geographical position where the off-line air conditioner external unit is located;
s240, when the air temperature value data are not larger than the set air temperature threshold value, determining a target air conditioner external unit in the offline air conditioner external units;
and S250, sending early warning prompt information to the user bound with the target air conditioner external unit.
According to the anti-freezing early warning method for the air conditioner external unit provided by the embodiment of the invention, when the air conditioner external unit is normally powered on, the reported data can be sent to the server, so that the server can receive the reported data of the air conditioner external unit. And if the reported data of the air conditioner external unit is not received within the preset time, determining that the air conditioner external unit is not electrified, and taking the air conditioner external unit which is not electrified as an offline air conditioner external unit. And then, determining air temperature value data in a set time period in the future corresponding to the geographical position where the off-line air-conditioning outdoor unit is located, when the air temperature value data is not greater than a set air temperature threshold value, determining the air-conditioning outdoor unit with the risk of being frozen in the off-line air-conditioning outdoor unit, and taking the air-conditioning outdoor unit with the risk of being frozen as a target air-conditioning outdoor unit, so that early warning prompt information can be sent to a user bound with the target air-conditioning outdoor unit to early warn that the air-conditioning outdoor unit has the risk of being frozen. Therefore, a user can know the risk of being frozen of the air conditioner external unit in advance, and the air conditioner external unit can be electrified in advance, so that a water tank connected with the air conditioner external unit is prevented from being frozen or frozen.
In some examples, a controller in the water system may have the function of controlling the temperature of the water tank after power is applied. Therefore, after the user receives the early warning prompt message, the outdoor unit in the air conditioner outdoor unit can be powered on, so that the controller in the water system is also powered on through the circuit main board of the outdoor unit, the temperature of the water tank is controlled, and the water tank is prevented from being frozen or frozen.
In some examples, when the air conditioner external unit is normally powered on, the report data is sent to the server, so that the server can receive the report data of the air conditioner external unit. After the air conditioner external unit is powered off, the reported data cannot be sent to the server any more, so that the server cannot receive the reported data any more. Therefore, the server can determine whether the reported data sent by the air conditioner external unit is received within a preset time at a specific time every day. And if the reported data of the air conditioner external unit are not received within the preset time, determining that the air conditioner external unit is in the non-electrified state, and taking the non-electrified air conditioner external unit as an offline air conditioner external unit. If the outdoor unit in the power-off state is in a low ambient temperature (e.g., below-4 °), the water tank may be easily frozen or damaged.
And if the reported data of the air conditioner external unit is received within the preset time, determining that the air conditioner external unit is in a power-off state within a period of time, and taking the powered air conditioner external unit as an online air conditioner external unit. And the server can perform corresponding operation (for example, control the temperature and the working mode of the air conditioner external unit) on the air conditioner external unit according to the reported data.
For example, the server may determine whether the report data sent by the air conditioner external unit is received within a predetermined time at 9 o' clock every day. Or, at 9 o' clock and half per day, determining whether the reported data sent by the air conditioner external unit is received within a preset time. Or, at 12 o' clock every day, determining whether the reported data sent by the air conditioner external unit is received within the preset time. Of course, in practical applications, the acquisition time may be designed and determined according to the requirements of practical applications, and is not limited herein.
For example, the predetermined time may be set as a set reporting time. For example, if the reporting time is set to 24h, the predetermined time may be set to 24 h. Of course, the predetermined time may be determined empirically or according to the requirements of the actual application, and is not limited herein.
In some examples, before determining the air temperature value data in the future set time period corresponding to the geographical location where the off-line outdoor unit is located, the method may further include: setting acquisition time at intervals, and acquiring air temperature value data of a plurality of different geographic positions in a set time period in the future; wherein the set time period is not less than the set acquisition time. For example, the acquisition time is set at intervals, and the air temperature value data in the future set time period for each region across the country is acquired. Wherein, each region in the country can be the minimum region precision of the current weather forecast corresponding forecast. For example, if the minimum regional accuracy is accurate to county level cities, the temperature value data in the weather forecast of each county level city in the country can be acquired.
For example, the future set time period may be set to 24h, 48h, 60h, 72h, etc. in the future, which is not limited herein. The set acquisition time may be 6h, 12h, 24h, etc., and is not limited herein. For example, the set acquisition time may be 24h, and the future set time period may be set to be 48h in the future. Of course, the future set time period and the set obtaining time may be designed and determined according to the requirements of the practical application, and are not limited herein.
In some examples, determining the air temperature value data in the future set time period corresponding to the geographical location where the off-line air-conditioning outdoor unit is located may specifically include:
determining the geographical position of an off-line air conditioner external unit;
and determining the air temperature value data corresponding to the off-line air-conditioner external unit in the future set time period according to the acquired air temperature value data of the plurality of different geographical positions in the future set time period and the geographical position of the off-line air-conditioner external unit. For example, the air temperature value data of the geographical position A, B, C, D, E, F in the future set time slot is acquired, and if the off-line air-conditioning outdoor unit is located at the geographical position C, the air temperature value data of the geographical position C in the future set time slot may be used as the air temperature value data of the off-line air-conditioning outdoor unit in the future set time slot.
In some examples, determining the geographical location of the offline air-conditioning outdoor unit may specifically include:
determining user information bound by the off-line air conditioner external unit;
determining a manager corresponding to the off-line air-conditioning outdoor unit from the user information bound by the off-line air-conditioning outdoor unit;
and taking the geographical position of the off-line air-conditioning outdoor unit stored in the account of the administrator of the off-line air-conditioning outdoor unit as the geographical position of the off-line air-conditioning outdoor unit.
For example, the geographical location of the offline air-conditioning outdoor unit may be determined according to the geographical location set by an administrator bound to the offline air-conditioning outdoor unit. The geographical position set by the family administrator is the accurate geographical position of the off-line air conditioner external unit set during registration.
In some examples, when there is air temperature value data not greater than an air temperature threshold value in the air temperature value data corresponding to the offline air-conditioning outdoor unit, it is indicated that the offline air-conditioning outdoor unit is at risk of being frozen. Due to the off-line air conditioner outdoor unit, it has been in a power-off state for a while. If the environment temperature of the air-conditioning outdoor unit in the power-off state is low (e.g. below-4 °), if the air temperature value data of the environment where the air-conditioning outdoor unit is located is not greater than the air temperature threshold value, the water tank in the off-line air-conditioning outdoor unit may be easily frozen or damaged. In order to avoid freezing damage, early warning prompt information can be sent to the part of off-line air conditioner external units to prompt that the water tank in the air conditioner external units is frozen or frozen, so that users can take precautions in advance.
In some examples, when the air temperature value data not greater than the air temperature threshold does not exist in the air temperature value data corresponding to the offline air-conditioning outdoor unit, it is indicated that the water tank in the offline air-conditioning outdoor unit is less likely to be frozen, and therefore, the warning prompt information is not sent to the user corresponding to the offline air-conditioning outdoor unit.
Illustratively, the air temperature threshold value can be set to a value between-4 ℃ and 4 ℃. For example, the air temperature threshold may be set at-4 ℃, 0 ℃ or 4 ℃. Of course, in practical applications, the specific value of the air temperature threshold may be designed according to the requirements of practical applications, and is not limited herein.
In some examples, sending the warning prompt message to the user bound to the target air conditioner external unit may specifically include: and sending early warning prompt information to the user bound with the target air conditioner external unit at each interval of prompt time.
In some examples, the warning alert information may be transmitted to an administrator bound to the target air conditioner external unit. Or, the early warning prompt information can be sent to each common user bound with the target air conditioner external unit. Or, the early warning prompt information can be sent to the administrator and each common user bound with the target air conditioner external unit. Therefore, the user bound by the target air conditioner external unit can receive early warning prompt information in time.
For example, the user information bound by the air conditioner external unit may have a mobile phone number of the user, and a short message with warning prompt information may be sent to the mobile phone number to prompt the user. Or the early warning prompt information is directly sent through the APP. In specific implementation, early warning prompt information can be sent to a home administrator bound with the target air conditioner external unit at intervals of prompt time. The prompting time can be set to 5s, 1min, 10min, etc., and the specific value of the prompting time can be designed and determined according to the requirements of practical application, which is not limited herein.
In specific implementation, the server may perform data interaction with a plurality of air conditioner external units through a data interaction module disposed in the air conditioner external units. Therefore, there may be a plurality of determined target outdoor air conditioners, for example, the determined target outdoor air conditioners are: A1-A1000. The home administrator bound to the target air conditioner outdoor units A1-a 1000 is BA1～BA1000If the server is one-time for the family manager BA1～BA1000And respectively sending early warning prompt messages, which may cause high load of the server. In particular implementations, batches may be pulled at intervals of time (e.g., 5s) to be sent to family manager BA1～BA1000SendingAnd warning prompt information. For example, first for family manager BA1～BA100And respectively sending early warning prompt information. Then 5s later, and then the family manager BA101～BA200And respectively sending early warning prompt information. Then 5s later, and then the family manager BA201～BA300And respectively sending early warning prompt information. Then 5s later, and then the family manager BA301～BA400And respectively sending early warning prompt information. And then, the rest is done by analogy, and the description is omitted here.
In some examples, before determining that the outdoor unit is an offline outdoor unit, the method may further include: and emptying the information stored in the current prompt list. Therefore, information in the information stored in the current prompt list can be emptied first, and the storage space can be reduced.
In some examples, when determining a target outdoor unit of the offline outdoor units, the method further includes: and storing the user information bound by the target air conditioner external unit into the current prompt list. Therefore, the user needing to send the early warning prompt information is saved in the current prompt list which is emptied in advance for subsequent use.
In some examples, when determining a target outdoor unit of the offline outdoor units, the method may further include: and storing the target air conditioner external unit into a current target air conditioner external unit list. Therefore, the determined target air conditioner external unit can be stored in the current target air conditioner external unit list for subsequent use.
In some examples, after storing the user information bound to the target air conditioner external unit in the current prompt list, the method may further include: and emptying the information of the target air conditioner external unit stored in the current target air conditioner external unit list. After the user information bound by each target air conditioner external unit is determined, the data in the current target air conditioner external unit list are used, so that the data stored in the current target air conditioner external unit list can be emptied, and the fan-out space can be stored for the next time.
