Detailed Description
Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
Fig. 1 is a schematic block diagram of an offline control system 100 of an air conditioner according to an embodiment of the present invention. Referring to fig. 1, in some embodiments, an offline control system 100 of an air conditioner may include an air conditioner 110 and a terminal device 120.
The terminal device 120 may controllably interact with the air conditioner 110 for near field communication. The terminal device 120 is, for example, a mobile device, a computer, a vehicle-mounted device built in a floating car, or the like, or any combination thereof. In some embodiments, the mobile device may include, for example, a cell phone, a smart home device, a wearable device, a smart mobile device, a virtual reality device, and the like, or any combination thereof.
In order to successfully establish a near field communication data connection between the air conditioner 110 and the terminal device 120, in some embodiments of the present invention, the air conditioner 110 may be configured with a first near field communication module 111 and the terminal device 120120 may be configured with a second near field communication module 121. The air conditioner 110 and the terminal device 120 may generate radio frequency fields through the first near field communication module 111 and the second near field communication module 121, respectively. Either one of the air conditioner 110 and the terminal device 120 may be selected as an initiator device for establishing a near field communication data connection, and the other one may be selected as a target device for establishing a near field communication data connection. Specifically, for example, the air conditioner 110 may be used as an initiating device, the terminal device 120120 may be used as a target device, a near field communication signal may be sent through the first near field communication module 111, and the near field communication signal may be received through the second near field communication module 121, so as to establish a near field communication data connection between the air conditioner 110 and the terminal device 120120, and then the air conditioner 110 and the terminal device 120120 may implement information interaction through the first near field communication module 111 and the second near field communication module 121.
The near field communication data connection mode is a short-distance wireless communication technology, and the short-distance interactive authentication and identification process can be simplified. The specific technical characteristics and parameters of the near field communication are as follows: near Field Communication (NFC for short) data is transmitted in an inductive coupling manner, and the Near Field Communication (NFC) data transmission method has the characteristics of small transmission range, low cost, high bandwidth, low power consumption and the like, and has the characteristics of bidirectional connection and identification. The transmission rate of NFC data communication may be 106Kb/s, 212Kb/s, 424Kb/s or higher (the transmission rate of an RFID system under the ISO14443 standard is uniform and fixed at 106 Kb/s). In addition, in the aspect of safety, the near field communication is safer, the response time is shorter, and the method is suitable for application in a wireless short-distance transmission environment.
With continued reference to fig. 1, the air conditioner 110 may further include a processor 112 and a memory 113. The memory 113 may store a computer program, and the computer program, when executed by the processor 112, may be used to implement the offline control method for the air conditioner 110 according to any of the following embodiments and/or any combination of the following embodiments.
In addition, the air conditioner 110 may be further provided with a contact detection module. The contact detection module is connected to the processor 112 and is configured to detect whether the terminal device 120 is in contact with the air conditioner 110. At this time, the processor 112 may be further configured to obtain the first control instruction for the air conditioner 110 from the terminal device 120 through the near field communication data connection between the air conditioner 110 and the terminal device 120 when the network connection state of the air conditioner 110 is interrupted and the terminal device 120 comes into contact with the air conditioner 110, which helps to accurately determine the near field communication interaction opportunity and improves the accuracy of control.
The first control instruction is generated for the terminal device 120 based on a first environmental parameter or a user setting parameter of a space where the air conditioner 110 is deployed. The first environmental parameter is an ambient temperature parameter or a concentration of a harmful substance (which may include, for example, PM2.5, PM10, etc.). The first environment parameter may be obtained by the terminal device 120 itself, or may be obtained by the terminal device 120 through a corresponding detection instrument. For example, when the first environmental parameter is an environmental temperature parameter, the temperature sensor may be used to obtain an environmental temperature of a space where the air conditioner 110 is deployed, and then the terminal device 120 obtains the environmental temperature from the temperature sensor and generates a first control instruction for the air conditioner 110 based on the environmental temperature. For another example, when the first environmental parameter is a harmful substance concentration, the air quality detector (e.g., PM2.5 detector, PM10 detector) may be used to acquire the harmful substance concentration in the deployment space of the air conditioner 110, and then the terminal device 120 acquires the harmful substance concentration from the air quality detector and generates the first control instruction for the air conditioner 110 based on the harmful substance concentration.
In some embodiments, the air conditioner 110 may also be configured with a purge module 114. The purification module 114 may be configured to promote a reduction in the concentration of harmful substances in the space in which the air conditioner 110 is deployed, thereby improving air quality to provide a high-comfort environment for the user. The decontamination module 114 may include one or more decontamination units that are used in quantities related to the concentration of hazardous substances in the space in which the air conditioner 110 is deployed.
Fig. 2 is a schematic flowchart of an offline control method of the air conditioner 110 according to an embodiment of the present invention. Referring to fig. 2, in some embodiments of the present invention, the off-line control method of the air conditioner 110 may include steps S202 to S208.
In step S202, it is detected whether the network connection of the air conditioner 110 is interrupted.
In step S204, when the network connection interruption of the air conditioner 110 is detected, the near field communication data connection between the air conditioner 110 and the terminal device 120 is established.
In step S206, a first control instruction for the air conditioner 110 is acquired from the terminal device 120 through the near field communication data connection. Wherein the first control instruction is generated by the terminal device 120 based on a first environmental parameter or a user setting parameter of a space where the air conditioner 110 is deployed.
In step S208, the air conditioner 110 is controlled according to the first control command.
In the offline control method of the air conditioner 110 provided in the embodiment of the present invention, it is detected whether the network connection of the air conditioner 110 is interrupted, and when the network connection of the air conditioner 110 is detected to be interrupted, a near field communication data connection between the air conditioner 110 and the terminal device 120 is established, and then a first control instruction for the air conditioner 110 is acquired from the terminal device 120 through the established near field communication data connection, and then the air conditioner 110 is controlled according to the first control instruction. By adopting the embodiment of the invention, the off-line control of the air conditioner 110 can be realized in a near field communication data connection mode after the network connection of the air conditioner 110 is interrupted, the problem that the air conditioner cannot work normally due to disordered control is avoided, the method is particularly suitable for the air conditioner based on the network, and the information interaction is carried out by adopting the near field communication data connection, so that the probability of information interception can be effectively reduced, and the information transmission is safer and more reliable. Compared with the prior art in the fields of intelligent families, intelligent houses, intelligent household appliances, intelligent air conditioners and the like, the air conditioner 110 can be kept in a normal working state after network connection is interrupted, the intelligent level of the air conditioner 110 is improved, and the intelligent requirement of a user on the air conditioner 110 can be well met.
In some embodiments, the air conditioner 110 is configured with a first near field communication module 111, the terminal device 120 is configured with a second near field communication module 121, and a near field communication data connection between the air conditioner 110 and the terminal device 120120 is established through the first near field communication module 111 and the second near field communication module 121. In practical applications, as long as the air conditioner 110 with the first near field communication module 111 and the terminal device 120120 with the second near field communication module 121 are within an effective range where the first near field communication module 111 and the second near field communication module 121 can automatically recognize each other, the near field communication data connection between the air conditioner 110 and the terminal device 120 can be automatically established through the first near field communication module 111 and the second near field communication module 121, so as to simply, safely and quickly transmit data.
In practical applications, there may be a case where the near field communication data connection is not established successfully, for example, when the network connection of the air conditioner 110 is detected to be interrupted, but the near field communication function of the air conditioner 110 is not turned on, which inevitably results in the failure of the near field communication data connection establishment. In view of this, in some embodiments, the step of establishing the near field communication data connection with the second near field communication module 121 through the first near field communication module 111 upon detecting the network connection interruption of the air conditioner 110 may further include: when the network connection of the air conditioner 110 is detected to be interrupted, whether the first near field communication module 111 is started is detected, if the first near field communication module 111 is not started, a near field communication starting instruction can be generated to the first near field communication module 111 to start the first near field communication module 111, and then a near field communication data connection is established with the started second near field communication module 121 through the first near field communication module 111 to ensure the success of the establishment of the near field communication data connection. On the contrary, if it is detected that the first nfc module 111 is turned on after detecting the network connection interruption of the air conditioner 110, the establishment process of the nfc data connection may be directly performed.
In other embodiments, after the step of controlling the air conditioner 110 according to the first control instruction, it may be further detected whether the network connection of the air conditioner 110 is recovered to normal, and when it is detected that the network connection of the air conditioner 110 is recovered to normal, a near field communication shutdown instruction may be generated to the first near field communication module 111 to shut down the first near field communication module 111, so that the first near field communication module 111 may be shut down in time after the network connection of the air conditioner 110 is recovered to normal, which not only helps to prolong the service life of the device, but also saves energy.
In addition, in the process of detecting the network connection state of the air conditioner 110, if it is detected that the network connection is normal or has been restored to be normal, an online control scheme may be performed on the air conditioner. For example, a second environmental parameter of a space where the air conditioner 110 is deployed may be obtained, a second control instruction for the air conditioner 110 may be generated according to the second environmental parameter, and then the air conditioner 110 may be controlled according to the second control instruction, so that the air conditioner 110 may perform networking control by itself after the network connection of the air conditioner 110 is restored to normal, thereby avoiding excessive dependence on the terminal device 120 and improving flexibility of control.
The second environmental parameter is the same as the first environmental parameter, and may be an environmental temperature parameter or a harmful substance concentration (for example, PM2.5, PM10, etc. may be included). In practical applications, an air quality detector (e.g., a PM2.5 detector, a PM10 detector) may be used to obtain the concentration of the harmful substance in the deployment space of the air conditioner 110. Of course, the concentration of the harmful substance in the deployment space of the air conditioner 110 may also be obtained through the cloud server.
In some embodiments, when the second control command for the air conditioner 110 is generated according to the second environmental parameter, the second environmental parameter may be compared with a preset environmental parameter threshold, and the second control command may be generated according to the comparison result. Therefore, the most appropriate second control instruction can be automatically generated according to the second environmental parameter of the actual deployment space of the air conditioner 110, and the user experience is improved.
The preset environment parameter threshold value is set corresponding to the second environment parameter, when the second environment parameter is the environment temperature parameter, the preset environment parameter threshold value can be set corresponding to the preset temperature threshold value, and when the second environment parameter is the harmful substance concentration, the preset environment parameter threshold value can be set corresponding to the preset concentration threshold value. The preset environmental parameter threshold may be pre-stored in the memory of the air conditioner 110 to facilitate the control process.
Illustratively, when the second environmental parameter is an environmental temperature parameter and the preset environmental parameter is set to be a preset temperature threshold, the second control command may include a heating command and a cooling command. On the basis, the step of generating the second control instruction according to the comparison result may include: when the environmental temperature parameter is greater than or equal to the preset temperature threshold, generating a refrigeration instruction to control the air conditioner 110 to enter a refrigeration mode; when the ambient temperature parameter is lower than the preset temperature threshold, a heating instruction is generated to control the air conditioner 110 to enter a heating mode. Therefore, the rapid temperature rise or temperature fall of the space where the air conditioner 110 is arranged can be realized, and the environmental comfort level is greatly improved.
After the air conditioner 110 enters the cooling mode, a first temperature difference between the ambient temperature parameter and the preset temperature threshold value can be further calculated, and then the air supply temperature of the air conditioner 110 is adjusted according to the first temperature difference, so that the air supply temperature is increased along with the increase of the first temperature difference.
After the air conditioner 110 enters the heating mode, a second temperature difference between the ambient temperature parameter and the preset temperature threshold value can be further calculated, so that the air supply temperature of the air conditioner 110 is adjusted according to the second temperature difference, and the air supply temperature is reduced along with the increase of the first temperature difference.
The preset temperature threshold may also be set to a preset temperature range, and at this time, the step of generating the second control instruction according to the comparison result may further include: when the ambient temperature parameter is greater than or equal to the maximum value of the preset temperature range, generating a refrigeration instruction to control the air conditioner 110 to enter a refrigeration mode; when the environmental temperature parameter is lower than or equal to the minimum value of the preset temperature range, generating a heating instruction to control the air conditioner 110 to enter a heating mode; when the environmental temperature parameter is within the preset temperature range, the operation mode does not need to be switched, and the operation can be carried out according to the original operation mode.
In some embodiments, the air conditioner 110 may also be configured with a purification module 114. The purification module 114 may be configured to promote a reduction in the concentration of harmful substances in the space in which the air conditioner 110 is deployed, thereby improving air quality to provide a high-comfort environment for the user. The decontamination module 114 may include one or more decontamination units that are used in quantities related to the concentration of hazardous substances in the space in which the air conditioner 110 is deployed.
Illustratively, when the second environmental parameter is the concentration of the harmful substance and the preset environmental parameter is set to the preset concentration threshold, the second control command may include a purge start command. On the basis, the step of generating the second control instruction according to the comparison result may include: when the concentration of the harmful substance is greater than or equal to the preset concentration threshold, it is detected whether the purification module 114 is turned on, and when the purification module 114 is not turned on, a purification turn-on command is generated to the purification module 114 to turn on the purification module 114, so as to promote the reduction of the concentration of the harmful substance in the space where the air conditioner 110 is deployed. Of course, if it is detected that the purification module 114 is turned on, a concentration difference between the harmful substance concentration and a preset concentration threshold may be calculated, and the number of purification units used may be decreased as the concentration difference decreases. That is, the smaller the concentration difference, the fewer purification units that need to be put into use.
Thereafter, when the concentration of the harmful substance is reduced below the preset concentration threshold, a purge shutdown command may be generated to the purge module 114 to shut down the purge module 114.
Considering that frequent opening and closing of the purification module 114 may affect the service life of the purification module 114, in other embodiments, the preset concentration threshold may be set to a preset concentration range, so as to compare the harmful substance concentration with the preset concentration range. If the concentration of the harmful substance is greater than or equal to the maximum value of the preset concentration range, it is possible to detect whether the purification module 114 is turned on, and if the purification module 114 is not turned on, a purification turn-on command is generated to the purification module 114 to turn on the purification module 114. If the purification module 114 is turned on and the concentration of the harmful material is lower than the minimum value of the predetermined concentration range, a purification turn-off command may be generated to the purification module 114 to turn off the purification module 114. If the harmful material concentration falls within the preset concentration range, the operation state of the purification module 114 is not adjusted.
In other embodiments, it may also be detected whether the terminal device 120120 touches the air conditioner 110, and then when detecting that the terminal device 120120 touches the air conditioner 110, the first control instruction is transmitted to the air conditioner 110 through near field communication data transmission, so as to further improve the accuracy of the control.
