It should be noted that the air conditioner generally comprises an indoor MCU, an indoor EEPROM, an outdoor MCU and an outdoor EEPROM, and the embodiment of the invention can be controlled and executed by the indoor MCU and executed on the premise that the indoor MCU can be normally upgraded; wherein, a long-range upgrading flow of indoor MCU specifically includes: the method comprises the steps of firstly uploading a new indoor software version to a cloud server, then issuing an indoor MCU program upgrading instruction through a mobile phone APP, after receiving the instruction, the cloud server sends related codes to a WiFi module in the air conditioner, and the codes are transmitted to an indoor MCU chip through the WiFi module to be upgraded.
An embodiment of the present invention provides an upgrading method for an outdoor EEPROM of an air conditioner, which is a flowchart of a preferred embodiment of the upgrading method for the outdoor EEPROM of the air conditioner, as shown in fig. 1, and the method includes steps S11 to S15:
step S11, judging whether the outdoor EEPROM of the air conditioner needs to be upgraded;
step S12, when the outdoor EEPROM is judged to need to be upgraded, an upgrade flag is set, an outdoor unit of the air conditioner is electrified, and an upgrade request instruction is sent to the outdoor unit;
step S13, when receiving an upgrade response instruction returned by the outdoor unit, judging the running state of the air conditioner;
step S14, if the running state of the air conditioner is the standby state, at least one EEPROM data packet or/and at least one communication data packet is sent to the outdoor unit according to a preset first sending rule; if the running state of the air conditioner is the starting state, at least one EEPROM data packet or/and at least one communication data packet is sent to the outdoor unit according to a preset second sending rule; after receiving all the EEPROM data packets, the outdoor unit updates the data in the outdoor EEPROM according to all the EEPROM data packets and returns an update completion instruction;
and step S15, when the upgrade completion instruction is received, clearing the upgrade flag.
Specifically, the indoor MCU judges whether the outdoor EEPROM of the air conditioner needs to be upgraded, and when it is judged that the outdoor EEPROM needs to be upgraded, the indoor MCU sets an upgrade flag corresponding to the upgraded outdoor EEPROM (for example, the value of the upgrade flag is set to 1), controls the outdoor unit of the air conditioner to be powered on, and sends a corresponding outdoor EEPROM upgrade request instruction to the outdoor unit (for example, to the outdoor MCU of the outdoor unit); after receiving the upgrading request instruction, the outdoor unit responds to the upgrading request instruction and returns a corresponding upgrading response instruction to the indoor MCU; when the indoor MCU receives an upgrade response instruction returned by the outdoor unit, the current running state of the air conditioner is further judged, so that a packet sending rule of an EEPROM (electrically erasable programmable read-only memory) data packet and a communication data packet is determined according to the running state of the air conditioner, if the running state of the air conditioner is in a standby state, at least one EEPROM data packet or/and at least one communication data packet (the communication data packet at least comprises related control instructions of the air conditioner, such as an on-off control instruction, a temperature regulation control instruction, an air door regulation control instruction, an air speed regulation control instruction and the like) is sent to the outdoor unit according to a preset first sending rule; if the running state of the air conditioner is a starting state, at least one EEPROM data packet or/and at least one communication data packet is/are sent to the outdoor unit according to a preset second sending rule until all the EEPROM data packets are sent, after all the EEPROM data packets sent by the indoor MCU are received by the outdoor unit, the data stored in the outdoor EEPROM are updated according to all the received EEPROM data packets, and meanwhile, the outdoor unit returns a corresponding updating completion instruction to the indoor MCU; and when the indoor MCU receives an upgrade completion instruction returned by the outdoor unit, clearing the upgrade flag (for example, clearing the value of the upgrade flag to 0).
It should be noted that the EEPROM data packets sent by the indoor MCU to the outdoor unit include new outdoor EEPROM data required for upgrading, after the outdoor unit receives all the EEPROM data packets sent by the indoor MCU, the outdoor unit updates and replaces the data stored in the outdoor EEPROM with the data included in all the received EEPROM data packets, and if all the data is replaced, it indicates that the upgrading process of the outdoor EEPROM is completed.
According to the method for upgrading the outdoor EEPROM of the air conditioner, when the outdoor EEPROM is judged to be needed to be upgraded, an upgrading mark is set, an outdoor unit of the air conditioner is electrified, and an upgrading request instruction is sent to the outdoor unit; when an upgrading response instruction returned by the outdoor unit is received, at least one EEPROM data packet or/and at least one communication data packet is sent to the outdoor unit according to the running state of the air conditioner and a preset first sending rule or a preset second sending rule, so that the outdoor unit can upgrade and update data in the outdoor EEPROM according to all the EEPROM data packets after receiving all the EEPROM data packets, the outdoor EEPROM can be upgraded remotely, workers do not need to arrive at a field to solve problems, user requirements can be met rapidly and efficiently, user experience is improved, meanwhile, the communication data packets can be sent to the outdoor unit timely while the outdoor EEPROM is upgraded, and the control requirements of the user on the air conditioner can be responded.
In another preferred embodiment, the determining whether the outdoor EEPROM of the air conditioner needs to be upgraded specifically includes:
judging whether the outdoor EEPROM needs to be upgraded or not according to the received repair content of the user; or the like, or, alternatively,
analyzing big data of the air conditioner according to a preset time period;
and judging whether the outdoor EEPROM needs to be upgraded or not according to the analysis result.
Specifically, with the above embodiment, the indoor MCU may determine whether to upgrade the outdoor EEPROM of the air conditioner according to the received user repair content (for example, the user finds that the air conditioner is poor in effect and actively reports related content for repair); or cloud big data analysis may be performed on the air conditioner according to a preset time period, so as to determine whether the outdoor EEPROM of the air conditioner needs to be upgraded according to an analysis result.
As an improvement of the scheme, the EEPROM data packet is stored in an indoor MCU of the air conditioner in advance; the upgrading mark is arranged in an indoor EEPROM of the air conditioner.
Specifically, with the combination of the above embodiments, when the indoor MCU determines that the outdoor EEPROM needs to be upgraded, all EEPROM data packets required for the upgrade can be pre-stored in the FLASH of the indoor MCU for subsequent upgrade; and the indoor MCU can set an upgrade flag corresponding to the outdoor EEPROM for upgrading in the indoor EEPROM, and the indoor MCU can judge whether the upgrade process is finished or not by reading the upgrade flag value in the indoor EEPROM.
It should be noted that, an area may be separately defined in advance in the FLASH area of the indoor MCU for storing the outdoor EEPROM data, for example, the storage space of the outdoor EEPROM is 8k Bytes, and an area with a size of at least 8k Bytes may be separately defined in the FLASH area of the indoor MCU for storing the outdoor EEPROM data.
In another preferred embodiment, the communication data packet contains a control instruction of the air conditioner; if the operation state of the air conditioner is the standby state, sending at least one EEPROM packet or/and at least one communication packet to the outdoor unit according to a preset first sending rule, specifically including:
if the running state of the air conditioner is the standby state, at least one EEPROM data packet is sent to the outdoor unit according to a preset communication rate; after receiving each EEPROM data packet, the outdoor unit returns a corresponding first response instruction;
when a control instruction change request is received, updating the communication data packet according to the changed control instruction, and sending the updated communication data packet to the outdoor unit according to the communication rate; after receiving the updated communication data packet, the outdoor unit returns a corresponding second response instruction;
and when the second response instruction is received, continuously sending the EEPROM data packets to the outdoor unit according to a preset communication rate until all the EEPROM data packets are sent.
Specifically, in combination with the above embodiment, the communication data packet at least includes related control instructions of the air conditioner, such as a power on/off control instruction, a temperature regulation control instruction, an air door regulation control instruction, an air speed regulation control instruction, and the like; when the indoor MCU judges that the current operation state of the air conditioner is a standby state, at least one EEPROM data packet is sent to the outdoor unit according to a preset communication rate, and the outdoor unit returns a corresponding first response instruction to the indoor MCU after receiving each EEPROM data packet; in the process that the indoor MCU sends the EEPROM data packet to the outdoor unit, if a control instruction change request is received, the communication data packet is updated according to the changed control instruction, the updated communication data packet is sent to the outdoor unit according to the preset communication rate so as to send the latest control instruction to the outdoor unit, and the outdoor unit returns a corresponding second response instruction to the indoor MCU after receiving the updated communication data packet; when the indoor MCU receives a second response instruction returned by the outdoor unit, the outdoor unit continues to send EEPROM data packets to the outdoor unit according to the preset communication rate, and the like until all the EEPROM data packets are sent, correspondingly, after the outdoor unit receives all the EEPROM data packets sent by the indoor MCU, the outdoor unit updates and updates the data stored in the outdoor EEPROM according to all the received EEPROM data packets, and simultaneously, the outdoor unit returns a corresponding update completion instruction to the indoor MCU; and when the indoor MCU receives an upgrade completion instruction returned by the outdoor unit, the upgrade flag is cleared.
For example, assuming that the number of the EEPROM packets is 5, when the air conditioner is in a standby state, the indoor MCU first transmits the EEPROM packets to the outdoor unit according to the preset communication rate, if a control instruction change request is received after transmitting 2 EEPROM packets, the communication packets are updated according to the changed control instruction, and the updated communication packets (the number is one) are transmitted to the outdoor unit according to the preset communication rate, so as to transmit the latest control instruction to the outdoor unit, and after transmitting 1 updated communication packet, the EEPROM packets are continuously transmitted to the outdoor unit according to the preset communication rate, and so on until 5 EEPROM packets are transmitted.
It can be understood that if the control instruction change request is not received, the EEPROM data packets are sent to the outdoor unit until 5 EEPROM data packets are sent; and if the indoor MCU sends an EEPROM data packet to the outdoor unit when receiving the control instruction change request, sending an updated communication data packet to the outdoor unit after the current EEPROM data packet is sent.
It should be noted that, when the indoor MCU sends an EEPROM packet and a communication packet to the outdoor unit, since the data size is large, bytes for each transmission can be defined according to actual needs, that is, an appropriate communication rate is set for data transmission.
According to the method for upgrading the outdoor EEPROM of the air conditioner, the EEPROM data packets or/and the communication data packets are alternately sent to the outdoor unit according to the preset first sending rule and the preset communication speed, the outdoor EEPROM can be remotely upgraded and simultaneously the communication data packets can be sent to the outdoor unit in time, the outdoor EEPROM can be upgraded and updated in the shortest time possible, the control requirement of a user on the air conditioner can be responded in time, and the use of the user is not influenced.
In another preferred embodiment, the communication data packet contains a control instruction of the air conditioner; if the operation state of the air conditioner is the on state, sending at least one EEPROM packet or/and at least one communication packet to the outdoor unit according to a preset second sending rule, specifically including:
if the running state of the air conditioner is the starting state, the communication data packet is sent to the outdoor unit according to a preset communication rate; after receiving the communication data packet, the outdoor unit returns a corresponding second response instruction;
when the second response instruction is received, at least one EEPROM data packet is sent to the outdoor unit according to the communication rate; after receiving each EEPROM data packet, the outdoor unit returns a corresponding first response instruction;
when a control instruction change request is received, updating the communication data packet according to the changed control instruction, and sending the updated communication data packet to the outdoor unit according to the communication rate; after receiving the updated communication data packet, the outdoor unit returns the second response instruction;
and when the second response instruction is received, continuously sending the EEPROM data packets to the outdoor unit according to a preset communication rate until all the EEPROM data packets are sent.
Specifically, with reference to the above embodiment, when the indoor MCU determines that the current operation state of the air conditioner is the on state, a communication data packet is sent to the outdoor unit according to a preset communication rate, and after receiving the communication data packet, the outdoor unit returns a corresponding second response instruction to the indoor MCU; when the indoor MCU receives a second response instruction returned by the outdoor unit, at least one EEPROM data packet is sent to the outdoor unit according to the preset communication rate, and the outdoor unit returns a corresponding first response instruction to the indoor MCU after receiving each EEPROM data packet; in the process that the indoor MCU sends the EEPROM data packet to the outdoor unit, if a control instruction change request is received, the communication data packet is updated according to the changed control instruction, the updated communication data packet is sent to the outdoor unit according to the preset communication rate so as to send the latest control instruction to the outdoor unit, and the outdoor unit returns a corresponding second response instruction to the indoor MCU after receiving the updated communication data packet; when the indoor MCU receives a second response instruction returned by the outdoor unit, the outdoor unit continues to send EEPROM data packets to the outdoor unit according to the preset communication rate, and the like until all the EEPROM data packets are sent, correspondingly, after the outdoor unit receives all the EEPROM data packets sent by the indoor MCU, the outdoor unit updates and updates the data stored in the outdoor EEPROM according to all the received EEPROM data packets, and simultaneously, the outdoor unit returns a corresponding update completion instruction to the indoor MCU; and when the indoor MCU receives an upgrade completion instruction returned by the outdoor unit, the upgrade flag is cleared.
For example, assuming that the number of the EEPROM packets is 5, when the air conditioner is in an on state, the indoor MCU first sends a communication packet to the outdoor unit according to a preset communication rate, and then sends the EEPROM packet to the outdoor unit according to the preset communication rate, if a control instruction change request is received after 2 EEPROM packets are sent, the communication packet is updated according to the changed control instruction, and sends the updated communication packet (the number is one) to the outdoor unit according to the preset communication rate, so as to send the latest control instruction to the outdoor unit, and after 1 updated communication packet is sent, the EEPROM packet continues to be sent to the outdoor unit according to the preset communication rate, and so on until 5 EEPROM packets are sent.
It can be understood that if the control command change request is not received, the EEPROM packet is always sent to the outdoor unit after one communication packet is sent to the outdoor unit; if the indoor MCU sends an EEPROM data packet to the outdoor unit when receiving a control instruction change request, then sending an updated communication data packet to the outdoor unit after the current data packet is sent; if the control instruction change request is received again in the process of sending the EEPROM data packet to the outdoor unit, the communication data packet which is updated again is sent first, and then the EEPROM data packet is sent again until 5 EEPROM data packets are sent.
In a further preferred embodiment, after said clearing said upgrade flag when said upgrade complete instruction is received, said method further comprises:

and if the outdoor EEPROM needs to be upgraded, judging that the upgrading treatment of the outdoor EEPROM fails, resetting the upgrading mark, electrifying the outdoor unit, and sending the upgrading request instruction to the outdoor unit so as to perform corresponding upgrading treatment on the outdoor EEPROM.
Specifically, with the above embodiment, after the data in the outdoor EEPROM is updated and updated, if the compressor is powered on again after being shut down, the operation is performed according to the updated data, which indicates that the outdoor EEPROM is successfully updated, the outdoor unit returns a corresponding update completion instruction to the indoor MCU, and if the compressor is not powered on again after being shut down, the update of the outdoor EEPROM fails, and the update process needs to be performed again, therefore, after the indoor MCU receives the update completion instruction returned by the outdoor unit and clears the update flag, the indoor MCU can determine again whether the outdoor EEPROM of the air conditioner needs to be updated, and when it is determined that the outdoor EEPROM needs to be updated, the previous update process on the outdoor EEPROM fails, the indoor MCU sets the update flag corresponding to the updated outdoor EEPROM again, controls the outdoor unit of the air conditioner to be powered on, and sends a corresponding outdoor EEPROM request instruction to the outdoor unit to perform a corresponding update process on the outdoor EEPROM, the subsequent upgrade processing procedure is the same as the above embodiment, and is not described herein again.
In yet another preferred embodiment, the method further comprises:
when the upgrading treatment on the outdoor EEPROM is judged to be failed for N times continuously, the upgrading treatment on the outdoor EEPROM is stopped; wherein N > 2.
Specifically, with reference to the foregoing embodiment, when the indoor MCU determines that the upgrade process on the outdoor EEPROM fails for N consecutive times (N >2, for example, N ═ 3), the indoor MCU does not perform the upgrade process on the outdoor EEPROM any more, and it can be understood that the air conditioner continues to operate according to the relevant data parameters before the upgrade.
