The embodiment provides an air conditioner upgrading method, which is applied to an air conditioning system, wherein the air conditioning system comprises an air conditioner inner unit and an air conditioner outer unit, as shown in fig. 1, and the method comprises the following steps:
s10, the air conditioner indoor unit acquires upgrade data, wherein the upgrade data are used for upgrading operation parameters stored in the air conditioner outdoor unit.
Specifically, the upgrade data is data for upgrading operation parameters in the external air conditioner, wherein the operation parameters in the external air conditioner can be stored in an electrified erasable programmable read-only memory assembled in the external air conditioner. The charged erasable programmable read-only memory is assembled on a control main board of the air conditioner external unit and stores operation parameters for controlling the operation of the air conditioner, and the operation parameters in the charged erasable programmable read-only memory are not lost when the air conditioner is powered down.
Further, the upgrade data may be issued to the air conditioner indoor unit through the cloud, or may be transmitted to the air conditioner indoor unit through an external device (for example, a smart phone or the like) connected to the air conditioner indoor unit. In an implementation manner of this embodiment, the upgrade data is sent to the air conditioner indoor unit through the cloud. Therefore, the air conditioner indoor unit is connected with the cloud end, and the upgrade data are obtained through the cloud end. For example, when the cloud end is configured with upgrade data of operation parameters in the air conditioner external unit, the cloud end issues an upgrade instruction to the air conditioner internal unit, so that the air conditioner internal unit obtains the upgrade data from the cloud end in an upgrade mode. Of course, in practical applications, the air conditioner indoor unit may further acquire the upgrade data in other manners, for example, the air conditioner indoor unit receives a control instruction, and sends an upgrade request to the cloud according to the control instruction, so that the cloud sends the upgrade data as upgrade data of the air conditioner indoor unit to the air conditioner indoor unit, so that the air conditioner indoor unit may acquire the upgrade data online.
S20, the air conditioner internal unit transmits the upgrade data to the air conditioner external unit.
Specifically, the air conditioner internal unit is communicated with the air conditioner external unit, and the upgrade data is sent to the air conditioner external unit through the air conditioner internal unit, so that the air conditioner external unit can acquire the upgrade data, and the upgrade of the operation parameters stored by the air conditioner external unit is realized. In addition, before the upgrade data is transmitted to the air conditioner external unit, the air conditioner internal unit needs to communicate with the air conditioner external unit to negotiate to determine the use of the upgrade data, so that the upgrade data is used for upgrading the operation parameters stored by the air conditioner internal unit. Thus, in one implementation manner of this embodiment, before the air conditioner indoor unit transmits the upgrade data to the air conditioner outdoor unit, the method includes:
correspondingly, as shown in fig. 2, the sending, by the air conditioner indoor unit, the first upgrade data to the air conditioner outdoor unit specifically includes:
s21, the air conditioner internal unit sends request information to the air conditioner external unit;
s22, the air conditioner external unit receives the request information, generates response information based on the request information and sends the response information to the air conditioner internal unit;
s23, the air conditioner internal unit receives the response information and sends upgrading data to the air conditioner external unit based on the response information.
Specifically, the request information is sent by the air conditioner internal unit to the air conditioner external unit so as to request the air conditioner external unit to perform operation parameter upgrading communication, wherein the request information can comprise an upgrading identifier, and the upgrading identifier is used for indicating that operation parameter upgrading is started. In addition, the request information may be sent in a preset data format, where the data address code field, the data code field and the check code field in the preset data format may store preset characters, and the preset characters are used to indicate that the air conditioner indoor unit requests to perform operation parameter upgrade communication to the air conditioner outdoor unit.
Further, the request information may be generated by the air conditioner indoor unit according to a trigger instruction sent by the external device, may be generated based on a trigger instruction generated by the air conditioner indoor unit to the remote control device, or may be triggered by a user triggering a trigger button set on the air conditioner indoor unit. Of course, it should be noted that, when the air conditioner indoor unit sends the request information to the air conditioner outdoor unit, the air conditioner indoor unit stores upgrade data for upgrading the operation parameters. It can be understood that when the air conditioner internal unit acquires the upgrade data, the request information can be automatically triggered; the upgrade data is stored and a trigger instruction for generating the request information is received.
Further, the response information is generated by the air conditioner external unit based on the request information and is used for indicating that the air conditioner external unit enters an operation parameter communication state, so that the air conditioner internal unit sends upgrading data to the air conditioner external unit based on the response information. In addition, the response information can be sent in a preset data format, wherein a data address code field, a data code field and a check code field in the data format can store response characters, and the response characters are used for indicating the running parameter upgrading communication state of the air conditioner external unit.
Further, the air conditioner indoor unit transmitting the upgrade data to an air conditioner outdoor unit specifically includes:
the air conditioner inner unit receives feedback information sent by the air conditioner outer unit, wherein the feedback information carries a feedback check code;
if the feedback check code is the same as the check code corresponding to the upgrade data, finishing the upgrade of the operation parameters of the air conditioner external unit;
and if the feedback check code is different from the check code corresponding to the upgrade data, the step of transmitting the upgrade data to the air conditioner external unit is executed again by the air conditioner internal unit.
Specifically, the feedback check code is generated by the air conditioner external unit based on the upgrade data and is used for representing the data identifier of the received upgrade data; the preset check code is a data identifier which is obtained in advance by the air conditioner indoor unit and used for identifying the upgrade data. After the feedback check code is received by the air conditioner internal unit, comparing the feedback check code with the preset check code to determine whether upgrade data received by the air conditioner external unit are identical with upgrade data sent by the air conditioner internal unit, if so, indicating that the operation parameters of the air conditioner external unit are upgraded, if not, indicating that the air conditioner external unit does not acquire the upgrade data to be configured, and then retransmitting the upgrade data by the air conditioner internal unit and recording the repeated sending times; and if the repeated transmission times reach the time threshold, judging that the operation parameters of the air conditioner external unit are failed to upgrade. The frequency threshold is preset, for example, 3 times, 4 times, etc.
In one implementation of this embodiment, the upgrade data includes a data address code and a data code, and the feedback verification code is generated according to the data address code and the data code. The feedback verification code can be generated by the external air conditioner according to the data address code and the data code written by the received upgrade data, or can be written and read by the external air conditioner directly from the upgrade data. It can be understood that the upgrade data may carry a check code generated according to the data address code and the data code, and after the air conditioner external unit receives the upgrade data, the air conditioner external unit reads the check code in the upgrade data, and uses the read check code as a feedback check code; the upgrade data does not carry a check code, and after the air conditioner external unit obtains the upgrade data, the check code is generated based on the data address code and the data code in the upgrade data. In addition, the check code corresponding to the upgrade data is stored in the air conditioner internal unit, and the check code corresponding to the upgrade data is generated by the air conditioner internal unit according to the data address code and the data code corresponding to the upgrade data and is used for verifying whether the feedback check code sent by the air conditioner external unit is correct, wherein the check code corresponding to the upgrade data is the same as the generation process of the feedback check code, and the generation process of the feedback check code is described as an example.
In a specific implementation manner of this embodiment, the feedback check code is generated by the external air conditioner according to the data address code and the data code in the upgrade data, and the generating process of the feedback check code specifically may include:
the external air conditioner reads the data address code carried by the upgrade data and the data code;
and adding the data address code and the data code, and performing inverting operation on the obtained result to generate a feedback check code.
Specifically, the data address code and the data code are correspondingly added according to the data bit, and when the data obtained by adding the data bit A corresponding to the data bit A in the first data code needs carry, the difference between the data and the binary number is directly adopted as the added data bit, and carry operation is not carried out. For example, the data bit a and the data bit B are all decimal, wherein the data corresponding to the data bit a is 5, and the data corresponding to the data bit B is 8, and then the data bit a and the data bit B are added to obtain the data of 3. In addition, in one implementation manner of this embodiment, the first upgrade data is stored in a preset data format, where a data address code occupies two bytes, a data code occupies two bytes, and a check code occupies one byte; the first check code may thus be generated from one byte in the data address code and one byte in the data code, e.g. the first check code is generated from the first bit byte in the data address code and the first bit byte in the data code. For example, if the data corresponding to the first byte in the data address code is 1 and the data corresponding to the first byte in the data code is 1, the address bit 0x0001 in the 16-ary representation and the data bit 0x0001 in the 16-ary representation are added to obtain 0x0002, and the inverse is the first check code 0Xfffd.
Further, in an implementation manner of this embodiment, when the air conditioner indoor unit transmits the upgrade data to the air conditioner outdoor unit, the upgrade data may be divided into a plurality of data segments, and each data segment obtained by dividing forms an upgrade data sequence according to a position sequence of the data segment in the upgrade data, and the air conditioner indoor unit sequentially sends each data segment in the upgrade data sequence to the air conditioner outdoor unit. Each data segment in the upgrade data sequence forms one upgrade data, which is respectively recorded as a first upgrade data, a second upgrade data, and an nth upgrade data, wherein N is the total number of the data segments in the upgrade data sequence. The first upgrade data, the second upgrade data, and the nth upgrade data each include a data address code and a data code, the data address codes of the upgrade data in the upgrade data sequence are different from each other, and the data codes of the upgrade data in the upgrade data sequence are different from each other.
In addition, the first upgrade data, the second upgrade data and the third, the nth upgrade data can be stored in a preset data format, the preset data format is determined by negotiation between the air conditioner internal unit and the air conditioner external unit, and when the air conditioner internal unit sends the first data to the air conditioner external unit, the first data is stored in the preset data format; when the air conditioner external unit sends second data to the air conditioner internal unit, the second data is stored in the preset data format, so that the air conditioner internal unit can analyze the second data, and the air conditioner external unit can analyze the first data.
In one implementation manner, the preset data format includes a data address code field, a data code field and a check code field, wherein the data address code field is used for storing a data address; the data code field is used for storing data content, and the check code field is used for storing check codes corresponding to the data. Furthermore, the data address codeword takes up two bytes, one for storing the upper 8 bits and the lower 8 bits of the address, respectively, e.g., the first byte of the two bytes is used to store the upper 8 bits of the address and the second byte is used to store the lower 8 bits of the address. The data codeword takes up two bytes, one for storing the upper 8 bits and the lower 8 bits of data, respectively, e.g., the first byte of the two bytes is used to store the upper 8 bits of data and the second byte is used to store the lower 8 bits of data. The check code field occupies 1 byte, and is used for storing check codes.
Further, the data address code in each upgrade data in the upgrade data sequence is stored in the data address code field, and the data code in each upgrade data in the upgrade data sequence is stored in the data code field. The first upgrade data is described here as an example. The data address code of the first upgrade data is stored in the data address code field, and the data code of the first upgrade data is stored in the data code field. In addition, since the first liter of data may not include the check code, when the first upgrade of data does not include the check code, the check code fields may be null, may be both 0, and the like. When the air conditioner external unit acquires the first upgrade data, the data address of the first upgrade data can be read from the data address code field, so that the data code field reads the data content of the first upgrade data, the data to be upgraded corresponding to the first upgrade data can be searched in the operation parameters of the air conditioner external unit according to the data address, and the data to be upgraded is replaced by the data code to be searched for upgrading.
Further, in an implementation manner of this embodiment, the sending, by the air conditioner internal unit, upgrade data to the air conditioner external unit may include:
dividing the upgrade data by the air conditioner indoor unit to obtain an upgrade data sequence;
taking the first upgrade data in the upgrade data sequence as target upgrade data, sending the target upgrade data to an air conditioner external unit, and receiving feedback data sent by the air conditioner external unit, wherein the feedback data carries a first check code;
the air conditioner indoor unit generates a second check code according to the first upgrade data, and compares the second check code with the first check code;
if the second check code is the same as the first check code, taking the next upgrade data of the target upgrade data as the target upgrade data, and continuously executing the step of sending the target upgrade data to the air conditioner external unit until all the upgrade data in the upgrade data sequence are sent;
and if the second check code is different from the first check code, taking the first upgrade data as target upgrade data, and re-executing the step of sending the target upgrade data to an air conditioner external unit.
Specifically, the feedback data is sent in a preset data format, that is, the feedback data includes a data address code field, a data code field and a check code field, where the first check code is stored in the check code field, and the data address code field and the data code field may be null or both be 0 and the like.
Further, the first check code may be generated by an air conditioner internal unit or may be generated by an air conditioner external unit. When the first check code is generated by the air conditioner internal unit, the air conditioner internal unit adds the first check code into first upgrade data and sends the first upgrade data to the air conditioner external unit, and when the air conditioner external unit receives the first upgrade data, the first upgrade data is read to carry the first check code and is used as feedback data to be sent to the air conditioner internal unit. When the first check code is generated by an external unit of the air conditioner, the first upgrade data does not carry the check code; when the air conditioner external unit receives first upgrade data sent by the air conditioner internal unit, the air conditioner external unit generates a first check code according to a data address code and a data code included in the first upgrade data, and sends the first check code to the air conditioner internal unit as feedback data. Of course, it should be noted that the generating process of the first check code is the same as the generating process of the feedback check code, for example, the generating process may refer to the generating process of the feedback data code according to the data address code and the data code in the first upgrade data, which is not described herein.
Further, the second check code is generated by the air conditioner indoor unit based on the first upgrade data, where a generating process of the second check code is the same as a generating process of the first check code, and specific reference may be made to the generating process of the first check code, which is not described herein. In addition, if the second check code is the same as the first check code, the instruction book air conditioner external unit receives the first upgrade data and the first upgrade data sent by the air conditioner internal unit, and at the moment, the first upgrade data is judged to be upgraded, and at the moment, whether the first upgrade data is the last upgrade data in an upgrade data sequence is judged; if the target upgrading data is not the last upgrading data, taking the last upgrading data of the target upgrading data as the target upgrading data; and continuing to send the target upgrade data to the air conditioner external unit until all the upgrade data in the upgrade data sequence are sent. If the second check code is different from the first check code, the fact that the first upgrade data received by the air conditioner external unit is different from the first upgrade data sent by the air conditioner internal unit is indicated, and at the moment, the fact that the first upgrade data is not upgraded is judged to be finished is carried out, and the first upgrade data is sent to the air conditioner external unit again. It can be understood that the first upgrade data is sent to the external air conditioner as target upgrade data, so that the external air conditioner upgrades the data to be upgraded corresponding to the first upgrade data again, and thus the accuracy of the upgrade of the operation parameters in the external air conditioner can be improved.
In addition, in order to avoid the air conditioner upgrade from entering the dead cycle, when the second check code is different from the first check code, the times of the second check code being different from the first check code are recorded. Meanwhile, when the first upgrade data is sent as second upgrade data, the number of times is read, if the number of times reaches a preset number of times threshold, the upgrade failure of the first upgrade data is recorded, and whether upgrade data different from the first upgrade exists or not is judged; if the upgrade data which is different from the first upgrade exists, one upgrade data is selected from the upgrade data which is different from the first upgrade to serve as second upgrade data, and the second upgrade data is sent to an air conditioner external unit. The preset frequency threshold is preset and is used for limiting the frequency of repeatedly generating the first upgrade data, for example, the preset frequency threshold is 20.
S30, the air conditioner external unit determines data to be upgraded corresponding to the upgrading data, and covers the data to be upgraded by adopting the upgrading data so as to upgrade the operation parameters in the air conditioner external unit.
Specifically, the air conditioner external unit receives the upgrade data and analyzes the upgrade data to obtain a data address code and a data code carried by the upgrade data; and determining the data to be upgraded corresponding to the upgrading data according to the data address code, and updating the data to be upgraded by adopting the data content corresponding to the data code. Correspondingly, in an implementation manner of this embodiment, the determining, by the external air conditioner, to-be-upgraded data corresponding to the upgrade data specifically includes:
the air conditioner internal unit transmits the upgrade data to the air conditioner external unit, wherein the upgrade data comprises a data address code and a data code;
and the air conditioner inner unit controls the air conditioner outer unit to determine the data to be upgraded corresponding to the data code based on the data address code.
Specifically, after receiving upgrade data sent by an air conditioner internal unit, an air conditioner external unit acquires a data address code corresponding to the upgrade data, determines a storage position of data to be upgraded corresponding to the upgrade data according to the data address code, and writes the data code of the upgrade data into the storage position to cover the data to be upgraded. Of course, it is worth to say that after the air conditioner external unit receives the upgrade data, the air conditioner external unit sends feedback information carrying a feedback check code to the air conditioner internal unit, so that the air conditioner internal unit finishes upgrading the operation parameters of the air conditioner external unit when the feedback check code is the same as a preset check code; and when the feedback check code is different from the preset check code, retransmitting the upgrade data to an external machine of the air conditioner.
In addition, in a specific implementation manner of the embodiment, the operation parameters in the external air conditioner are stored in an electrified erasable programmable read-only memory assembled in the external air conditioner. Therefore, after the air conditioner external unit receives the upgrade data through the air conditioner external unit mainboard, the upgrade data is written into the charged erasable programmable read-only memory so as to modify the data to be upgraded, which corresponds to the first upgrade data, in the charged erasable programmable read-only memory. The upgrade data is all operation parameters in the operation parameters corresponding to the charged erasable programmable read-only memory, and can also be part of operation parameters. It can be understood that when the operation parameters are modified by the air conditioner indoor unit, all the operation parameters in the charged erasable programmable read-only memory can be modified, and part of the operation parameters in the charged erasable programmable read-only memory can be modified.
Further, in an implementation manner of this embodiment, when the operation parameter in the air conditioner external unit is updated, the air conditioner internal unit needs to send end data to the air conditioner external unit, so that the air conditioner external unit knows that the operation parameter in the air conditioner external unit is updated, and stops performing the operation parameter updating communication with the air conditioner internal unit in the air conditioner external unit.
