Description
The technical field is as follows:
the invention relates to a novel WIFI communication method of an internet of things, and belongs to the technical field of refrigerators.
Background art:
air-cooled refrigerators in the current industry are generally classified into two types: one type is a traditional air-cooled refrigerator, and the control mode of the refrigerator is manual control and cannot be controlled remotely. The other is the mainstream product in the household appliance market, namely the intelligent air-cooled refrigerator, compared with the traditional air-cooled refrigerator, the intelligent air-cooled refrigerator is added with remote control loads such as a WIFI module and the like.
In the modern times, intelligent devices are becoming a necessary trend for the transformation of devices, and thus, the intelligent control of refrigerators is becoming an indispensable requirement.
The invention content is as follows:
the invention provides a novel WIFI communication method of the internet of things, aiming at solving the problems in the prior art, and the novel WIFI communication method can realize timely and accurate communication when a WIFI module is communicated with a display panel.
The technical scheme adopted by the invention is as follows: a novel WIFI communication method for the Internet of things comprises the following specific steps:
step 1: after the intelligent refrigerator is electrified and networked, when the display panel communicates with the WIFI module, the display panel firstly sends a guide code 0X7A to determine that the communication starts;
step 2: sending the address of the target equipment and determining the communication position;
and step 3: sending a source address, and identifying the identity of the equipment;
and 4, step 4: sending the message length of the data frame, and determining the size of the communication data frame, wherein the size of the communication data frame does not exceed 50 words at most;
and 5: sending the model code, and determining the type of the communication machine;
step 6: sending a command code, and identifying a data frame;
and 7: sending effective data for data transmission;
and 8: the data is subjected to CRC to ensure that the received data is accurate and error-free.
The invention has the following beneficial effects: according to the novel Internet of things WIFI communication method, when the display panel and the WIFI module perform data interaction, required information can be fed back accurately, the communication reliability of the display panel and the WIFI module is greatly improved, and the data interaction rigidness is greatly improved.
Description of the drawings:
fig. 1 is a flowchart of a novel internet-of-things WIFI communication method according to the present invention.
The specific implementation mode is as follows:
the invention will be further described with reference to the accompanying drawings.
As shown in fig. 1, the novel internet of things WIFI communication method of the present invention specifically includes the following steps:
step 1: after the intelligent refrigerator is electrified and networked, when the display panel communicates with the WIFI module, the display panel firstly sends a guide code 0X7A to determine that the communication starts;
step 2: sending the address of the target equipment and determining the communication position;
and step 3: sending a source address, and identifying the identity of the equipment;
and 4, step 4: sending the message length of the data frame, and determining the size of the communication data frame, wherein the size of the communication data frame does not exceed 50 words at most;
and 5: sending the model code, and determining the type of the communication machine;
step 6: sending a command code, and identifying a data frame;
and 7: sending effective data for data transmission;
and 8: the data is subjected to CRC to ensure that the received data is accurate and error-free.
The above-mentioned; the flow chart shows that the refrigerator display board determines whether communication with the WIFI module is started or not through the guide code, then sends a corresponding target address, identification bits of data to be transmitted and effective data, and finally carries out CRC (cyclic redundancy check) on the transmitted data.
According to the novel WIFI communication method of the internet of things, the guide code is added to confirm the start of data transmission, the accuracy of the transmission address is checked by sending the target address and the equipment address, the order of marking the data frame is added to ensure the accuracy and reliability of data transmission, and finally CRC checking is carried out on the transmitted data.
The foregoing is only a preferred embodiment of this invention and it should be noted that modifications can be made by those skilled in the art without departing from the principle of the invention and these modifications should also be considered as the protection scope of the invention.
