Therefore, the target maintenance equipment and the user side are connected respectively, so that the corresponding written-in file is determined from the user side, the written-in file is successfully forwarded to the target maintenance equipment, and the program writing of the target maintenance equipment is finally realized. Therefore, the flexible writing of the after-sale program of the non-intelligent household appliance can be completed based on the after-sale program writing method only by establishing communication connection with the target maintenance equipment in advance.
In this embodiment of the present invention, step 101 sends a communication request to the target maintenance device, specifically, after the power is turned on, the MCU of the target maintenance device is actively sent handshake information (for example, a serial data packet with a message type of 01), and when the MCU of the target maintenance device receives handshake success information returned by the target maintenance device and passes verification, it determines that a communication connection for data transmission has been successfully established.
It should be noted that the target maintenance device may be a non-intelligent appliance or an intelligent appliance.

Therefore, the write-in file is sent to the target maintenance equipment when the target maintenance equipment is ensured to be in an online state, so that the target maintenance equipment can be ensured to accurately receive the write-in file, and the efficiency and the accuracy of the after-sales program write-in method are improved.
Specifically, when it is determined that the status information is in the offline status, it is determined that the target maintenance device is disconnected from the communication connection with the after-sales program writing apparatus, and it is necessary to return to step 101 to reestablish the communication connection with the target maintenance device.

and sending the written feedback information to the user side.
In the embodiment of the invention, the receiving feedback information returned by the target maintenance equipment is received, and when the receiving feedback information is successful, the writing feedback information returned by the target maintenance equipment is received and sent to the user side. Therefore, after the target maintenance equipment is determined to successfully receive the written-in file, the written-in file cannot be continuously sent to the target maintenance equipment, then the target maintenance equipment writes in according to the written-in file, and write-in feedback information after writing in is obtained, so that the user side can conveniently determine the written-in result, and the use experience of the user is improved.

if yes, determining that the current heartbeat response information is overtime, and determining that the communication connection for establishing data transmission with the user terminal is abnormal.
In the embodiment of the invention, after the communication connection of data transmission is established with the user terminal through the TCP connection, the heartbeat response information sent by the user terminal is received according to the preset heartbeat frequency, the first time corresponding to the current heartbeat response information is recorded, when the time difference between the first time and the second time of the last recorded heartbeat response information is greater than the preset threshold value, the current heartbeat response information is determined to be overtime, the communication connection of data transmission with the user terminal is determined to be abnormal, and then the fault is required to be overhauled or the communication connection is required to be reestablished. Therefore, the communication connection with the user side can be confirmed in real time, and the response can be made in time when the communication connection is disconnected, so that the communication is ensured to be normal, and the efficiency of writing the after-sales program is further improved.
