On the basis of fig. 1 and 2, an embodiment of the present invention provides a data writing method, which is applied to an internet of things module 10 in fig. 1 and 2, please refer to fig. 3, fig. 3 is a flow chart of the data writing method provided by the present invention, the method includes the following steps:
step S100, when the internet of things module powers off and powers on again in the process of programming the data to be programmed to the air conditioner, if a programming inquiry command sent by the terminal is received, the data to be programmed is checked.
In this embodiment, the writing query command may be a query command for knowing whether the data writing is normally performed, which is periodically sent by the terminal 20 to the internet of things module 10 after the internet of things module 10 starts the data writing, where the writing query command can avoid abnormal interruption or abnormal termination of the writing caused by power failure of the internet of things module 10 in the writing process, and the terminal 20 cannot know that the writing is abnormal in time, so that the user cannot be given feedback of the abnormal writing condition in time, and on the other hand, when the internet of things module 10 is powered on again, the writing can be restarted automatically based on the searched writing query command, so that the manual intervention of a maintainer is avoided, and the re-writing efficiency is improved.
As a specific embodiment, after the internet of things module 10 starts data writing for a preset time period (the preset time period may be set according to needs, for example, the preset time period is 30 seconds), if the writing state information returned by the internet of things module 10 is not received, the terminal 20 periodically sends a writing query command to the internet of things module, the query period may be set according to needs, for example, the query period is set to be 5s for one query, if the number of times of query reaches the preset number of times, and if the writing state information fed back by the internet of things module 10 is not received yet, the terminal 20 determines that writing fails here, the preset number of times may be set according to needs, for example, the preset number of times may be set to be 5.
In this embodiment, since the internet of things module 10 is powered off in the programming process, in order to ensure the correctness of the programming data after the internet of things module 10 is powered on again, the data to be programmed in the Flash memory of the internet of things module 10 is checked before the data is re-programmed, so as to avoid that the wrong data to be programmed is programmed to the air conditioner 30, and the data update of the air conditioner 30 fails. As a specific implementation manner, the verification may include an integrity verification of the data to be programmed, and the verification method may be a CRC verification.
Step S110, if the data to be programmed passes the verification, re-programming the data to be programmed to the air conditioner.

In this embodiment, the internet of things module 10 writes the data to be written into the air conditioner 30 through the writing bus, and in general, the air conditioner includes an EEPROM (Electrically Erasable Programmable read only memory, i.e. an electrically erasable programmable read only memory) memory, which generally stores configuration information related to the air conditioner, such as model parameters stored in an air conditioner internal unit, compressor parameters stored in an air conditioner external unit, and the like. The data to be programmed is programmed into the air conditioner 30, which generally means that the data to be programmed is programmed into the EEPROM memory of the air conditioner 30.
According to the method provided by the embodiment of the invention, when the Internet of things module is powered off and powered on again in the process of writing data, the Internet of things module can read out the data to be written from the Flash memory and check the data based on the received writing inquiry command sent by the terminal without intervention of maintenance personnel, so that the re-writing of the data to be written is realized, and the writing efficiency in the scene is improved.
In this embodiment, in order to make the terminal 20 know the writing result in time, and to improve the success rate of writing by retry after the writing failure, and avoid unnecessary processing of the writing failure, the embodiment of the present invention further provides an implementation manner of feeding back the writing result and processing the writing result after step S110 on the basis of fig. 3, please refer to fig. 4, fig. 4 is a flowchart of another data writing method provided by the present invention, and step S110 further includes the following steps:
in step S120, if the data to be programmed is successfully programmed, a successful programming result is fed back to the terminal.
In step S130, if the writing of the data to be written fails, the data to be written is rewritten.
In step S140, if the number of writing times reaches the preset number of times and each writing fails, the writing result of the writing failure is fed back to the terminal.
In this embodiment, the preset times may be set according to the needs of the actual scenario, for example, the preset times are set to 5 times, if the number of times of programming reaches 2 times and the programming fails for 2 times, the internet of things module 10 stops retrying, does not continue to re-program the data to be programmed, and feeds back the programming result of the programming failure to the terminal 20, so as to avoid untimely feedback of the programming result caused by invalid retrying.
According to the method provided by the embodiment of the invention, when the programming is successful, the programming result of the programming is fed back to the terminal 20 in time, and when the programming is failed, the retry of the preset times is usually performed, so that the success rate of the programming is improved, and unnecessary processing of the programming failure is avoided.
In this embodiment, in order to correctly obtain the data to be programmed before programming the data to be programmed and to ensure the reliability of the data to be programmed, the embodiment of the present invention further provides an implementation manner for obtaining the data to be programmed, please refer to fig. 5, fig. 5 is a flowchart of another data programming method provided by the present invention, the method includes the following steps:
step 200, receiving a data transmission instruction sent by the terminal, wherein the data transmission instruction is used for starting a flow for transmitting data to be programmed.

Step 210, receiving data to be programmed sent by the terminal based on the data sending instruction.
Step 220, after the data to be programmed is received, checking the data to be programmed.
In this embodiment, the checking of the data to be programmed includes performing integrity checking of the data to be programmed, and the checking mode includes CRC checking.
And 230, if the data to be programmed passes the verification, storing the data to be programmed into a Flash memory and feeding back a verification completion message to the terminal.
In this embodiment, the checked data to be programmed is stored in the Flash memory, and the Flash memory has the characteristic that the data is not lost after power failure, so that the data to be programmed can still be automatically read from the Flash memory for re-programming after the internet of things module is powered up again after abnormal power failure in the programming process.
And step 240, if the data to be programmed fails to pass the verification, feeding back a message of failure verification to the terminal.
On the basis of fig. 5, the embodiment of the present invention further provides a specific implementation manner of writing the verified data to be written into the air conditioner 30, referring to fig. 6, fig. 6 is a flowchart of another data writing method provided by the present invention, and the method further includes the following steps:
