Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. The following description refers to the accompanying drawings in which the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
It should be noted that all actions of acquiring signals, information or data in the present application are performed under the premise of complying with the corresponding data protection regulation policy of the country of the location and obtaining the authorization given by the owner of the corresponding device.
Fig. 1 is a flowchart illustrating an air conditioner OTA upgrade control method according to an exemplary embodiment. As shown in fig. 1, the method includes the following steps.
In step S101, in response to receiving an OTA upgrade instruction generated by user triggering, an OTA upgrade data packet is obtained, where the OTA upgrade data packet includes an indoor unit upgrade data packet and an outdoor unit upgrade data packet.
The method of the scheme can be applied to the indoor unit controller of the air conditioner. When it is determined that an OTA upgrade is required, the indoor unit controller may output a prompt message to ask the user whether to perform the OTA upgrade. For example, the output dialog "detect new version, go on OTA upgrade immediately" may be controlled. The user may trigger the generation of an OTA upgrade instruction, for example, by clicking the soft key "yes". When receiving an OTA upgrading instruction generated by user triggering, the indoor unit controller can acquire an OTA upgrading data packet through the cloud management platform.
In step S102, when the air conditioner is operating, the communication baud rates of the indoor unit controller and the outdoor unit controller of the air conditioner are controlled to be adjusted from the first baud rate to a second baud rate, and the second baud rate is greater than the first baud rate.
The communication baud rate is the number of symbols of a transmission code element in a unit time, and is a measure of the transmission rate of the symbols. The first baud rate may be predetermined by the designer, and may be, for example, 1200 bps. The second baud rate may be predetermined by the designer, and may be, for example, 9600 bps. That is, if the air conditioner is running, the communication baud rate of the indoor unit controller and the outdoor unit controller of the air conditioner is controlled to be adjusted from the original smaller baud rate to the larger baud rate.
In step S103, if the air conditioner is in the non-heating operation mode, the outdoor unit upgrade data packet is sent to the outdoor unit controller, so that the outdoor unit controller performs OTA upgrade.
The operation mode of the air conditioner may include a heating operation mode and a non-heating operation mode. The non-heating operation mode of the air conditioner may include a cooling mode, a blowing mode, and a dehumidifying mode. And after receiving the outdoor unit upgrading data packet, the outdoor unit controller can control the outdoor unit to shut down and stop running, so that the outdoor unit controller can carry out OTA upgrading. When the air conditioner is in a non-heating mode, if the outdoor unit stops running and the indoor unit normally supplies air, the running effect of the air conditioner in the current non-heating working mode (a cooling mode, an air supply mode or a dehumidification mode) can be maintained for a period of time or to a certain extent. Therefore, when the outdoor unit controller is upgraded, the indoor unit controller can control the indoor unit to work normally to supply air.
In step S104, after the outdoor unit controller is upgraded, OTA upgrade is performed on the indoor unit controller according to the indoor unit upgrade data packet.
After the outdoor unit controller is upgraded, the indoor unit controller can control the indoor unit to be shut down and stop running, so that the indoor unit controller can be upgraded through OTA.
Through the technical scheme, the communication baud rates of the indoor unit controller and the outdoor unit controller are increased, so that the time for sending the outdoor unit upgrading data packet to the outdoor unit controller is shortened, the OTA upgrading time is shortened, and the indoor unit can be continuously controlled by the indoor controller to operate according to the non-heating working mode in the process of upgrading the outdoor controller under the condition that the air conditioner is in the non-heating working mode, so that the influence on the use of the air conditioner by a user due to OTA upgrading is reduced.
In another embodiment, if the air conditioner is in the non-heating operation mode in step S103, sending the outdoor unit upgrade data packet to the outdoor unit controller includes:
and if the air conditioner is in the non-heating working mode and the outdoor environment temperature is higher than the preset temperature threshold value, sending the outdoor unit upgrading data packet to the outdoor unit controller.
The temperature threshold may be preset by the designer, and may be, for example, 30 ℃. If the outdoor environment temperature is higher than the preset temperature threshold, the weather is considered to be hot, the requirement for cooling by the air conditioner is high, and at the moment, the upgrading of the outdoor unit controller can be prioritized, so that the indoor unit can normally supply air. When the air conditioner is in a non-heating working mode and the outdoor environment temperature is lower than a preset temperature threshold value, the weather is considered to be not very hot, the requirement of a user for cooling by using the air conditioner is not too high, and the outdoor unit controller and the indoor unit controller can be controlled to be upgraded at the same time.
In the embodiment, when the air conditioner is in a non-heating mode, the outdoor unit controller is preferentially upgraded only when the ambient temperature is higher than the preset ambient temperature threshold, and the indoor unit normally supplies air, so that the heat dissipation requirement of a user is reasonably ensured.
In yet another embodiment, the method further comprises:
if the air conditioner is in a non-heating working mode, acquiring a wind power gear of an indoor unit of the air conditioner in the OTA upgrading process of an outdoor unit controller;
if the wind gear of the indoor unit is lower than a preset wind gear threshold, adjusting the wind gear of the indoor unit to be the wind gear threshold;
and if the wind power gear of the indoor unit is higher than the wind power gear threshold value, the wind power gear of the indoor unit is adjusted to be higher.
The wind gear threshold value may be preset by the designer, and may be 4, for example. In the upgrading process of the outdoor unit controller OTA, if the wind gear of the indoor unit is lower than a preset wind gear threshold, the wind gear set by a user is considered to be lower, and the air volume demand is smaller, the wind gear of the indoor unit is adjusted to be the wind gear threshold. That is, when the wind gear set by the user is low, the wind gear threshold is uniformly increased to a high wind gear threshold for blowing, so that certain compensation can be performed on the operation effect of the air conditioner during the shutdown of the outdoor unit. When the wind gear of the indoor unit is equal to the preset wind gear threshold value, the wind gear can not be adjusted, and the current wind gear threshold value is kept for blowing.
If the wind gear of the indoor unit is higher than the preset wind gear threshold value, the wind gear set by a user is considered to be higher, the air volume requirement is higher, at the moment, the wind gear is also correspondingly increased, and certain compensation is performed on the air conditioner operation effect. Preferably, the predetermined level may be increased, for example, a first gear may be increased, based on the gear set by the user, so that a certain compensation is made in the operation effect of the air conditioner during the shutdown of the outdoor unit.
In this embodiment, in the upgrading process of the outdoor unit, the wind gear is adjusted according to the wind gear condition set by the user. The influence of poor air conditioner operation effect caused by shutdown of the outdoor unit due to OTA upgrading of the outdoor unit controller is reduced.
In yet another embodiment, the method further comprises:
after the outdoor unit upgrading data packet is sent to the outdoor unit controller, the communication baud rate of the indoor unit controller and the outdoor unit controller is controlled to be adjusted to the first baud rate from the second baud rate.
After the outdoor unit upgrading data packet is sent to the outdoor unit controller, it can be considered that a higher communication baud rate is not needed to transmit the outdoor unit upgrading data packet, and the first baud rate can meet the communication requirements of the indoor unit controller and the outdoor unit controller in a normal working state, so that the communication baud rates of the indoor unit controller and the outdoor unit controller are controlled to be adjusted to the first baud rate from the second baud rate.
The baud rate can be adjusted immediately after the outdoor unit upgrading data packet is sent to the outdoor unit controller, or the baud rate can be adjusted after the outdoor unit controller is upgraded.
The indoor unit upgrading packet is stored in the indoor unit controller, and if the outdoor unit is upgraded, the indoor unit controller is upgraded according to the indoor unit upgrading data packet.
In the embodiment, after the outdoor unit upgrading data packet is sent to the outdoor unit controller, the communication baud rates of the indoor unit controller and the outdoor unit controller are controlled to be adjusted from the second baud rate to the first baud rate, and the power consumption is reduced.
In yet another embodiment, the method further comprises:
after the OTA upgrading of the indoor unit controller is completed, the indoor unit of the air conditioner is controlled to operate in a non-heating working mode before the OTA upgrading, and the target temperature of the current operation of the air conditioner is set to be lower than the set temperature before the OTA upgrading within a preset first time.
The first time period may be preset by the designer, and may be 30min, for example. If the indoor unit controller is upgraded, the OTA upgrading of the air conditioner is finished, and the air conditioner can be controlled to operate in a non-heating working mode before the OTA upgrading. Although the indoor unit keeps blowing during the upgrade of the outdoor unit controller, the working effect of normal operation of the indoor and outdoor units cannot be completely achieved. Therefore, after the air conditioner OTA upgrade is completed, the indoor temperature is generally higher than the temperature set by the user before the OTA upgrade. The target temperature of the current operation of the air conditioner is set to be lower than the set temperature before OTA upgrading within the preset first time, the set temperature before OTA upgrading can be reached more quickly, and the use experience of a user is improved. For example, the target temperature of the current operation of the air conditioner may be set to be 2 ℃ lower than the set temperature before the OTA upgrade within 30min after the OTA upgrade of the indoor unit controller is completed.
In yet another embodiment, the method further comprises:
and if the air conditioner is in a heating working mode, sending the outdoor unit upgrading data packet to the outdoor unit controller, and controlling the outdoor unit controller and the indoor controller to simultaneously carry out OTA upgrading.
If the air conditioner is in the heating working mode, the weather is considered to be cold, and the user does not have the refrigeration requirement. When the outdoor unit controller OTA is upgraded, the outdoor unit is shut down and does not perform heating, and if the indoor unit controller works normally, the indoor unit sends cold air. Therefore, both the outdoor unit and the outdoor unit can be temporarily stopped, the outdoor unit upgrading data packet is sent to the outdoor unit controller, and the indoor unit controller and the outdoor unit controller are controlled to simultaneously carry out OTA upgrading.
In the embodiment, when the air conditioner is in the heating working mode, the outdoor unit controller is not preferentially upgraded, but the outdoor unit controller and the indoor unit controller are controlled to be upgraded simultaneously, so that the air conditioner OTA upgrading time is shortened.
In yet another embodiment, the method further comprises:
and after the outdoor unit controller and the indoor controller are upgraded through the OTA, controlling the indoor unit of the air conditioner to operate in a heating working mode before the OTA is upgraded, and setting the target temperature of the current operation of the air conditioner to be higher than the set temperature before the OTA is upgraded within a preset second time.
The second time period may be preset by the designer, and may be, for example, 30 min. If the indoor unit controller and the outdoor unit controller are upgraded, namely the OTA upgrade of the air conditioner is finished, the air conditioner can be controlled to operate in a heating working mode before the OTA upgrade. Because the original heating effect of the air conditioner is delayed during the simultaneous upgrade of the outdoor unit controller and the indoor unit controller, after the OTA upgrade of the air conditioner is completed, the indoor temperature is usually lower than the temperature set by a user before the OTA upgrade. The target temperature of the current operation of the air conditioner is set to be higher than the set temperature before OTA upgrading within the preset second time, the set temperature before OTA upgrading can be reached more quickly, and the use experience of a user is improved. For example, after the OTA upgrade of the indoor unit controller is completed, the target temperature of the current operation of the air conditioner may be set to be 2 ℃ higher than the set temperature before the OTA upgrade within 30 min.
In yet another embodiment, the method further comprises: when the air conditioner is in a shutdown state and the shutdown duration is longer than a preset third duration, the outdoor unit upgrading data packet is sent to the outdoor unit controller at a first baud rate, and the outdoor unit controller and the indoor controller are controlled to simultaneously carry out OTA upgrading.
The third off-time period may be preset by the designer, and may be 2h, for example. When the air conditioner is in a shutdown state and the shutdown duration is longer than the preset shutdown duration, the user can be considered to have no requirement for using the air conditioner in a short time, therefore, OTA upgrading does not affect the use of the air conditioner by the user, an outdoor unit upgrading data packet can be sent to an outdoor unit controller at a conventional smaller first baud rate, and the indoor unit controller and the outdoor unit controller are controlled to carry out OTA upgrading simultaneously.
In the embodiment, when the air conditioner is not used temporarily, the indoor unit controller and the outdoor unit controller are controlled to be upgraded by OTA at the same time, the upgrading time is shortened, the upgrading data packet is transmitted by using a smaller communication baud rate, the communication baud rate is not switched, and the control step is simplified.
Fig. 2 is a flowchart illustrating an air conditioner OTA upgrade control method according to another exemplary embodiment. The steps in the embodiment of fig. 2 are a combination of the steps in the above embodiments, and specifically include the following steps.
