Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. The components of embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without making any creative effort, shall fall within the protection scope of the present invention.
In the process of assembling and transmitting the existing message body, the state before the message body needs to be inquired, logic mutual exclusion processing is carried out in the server, and whether the operation can be executed or not is judged. If the mutual exclusion exists, an error message is directly returned, and then the state needing to be controlled is replaced in the inquiry state, and an instruction is issued, so that the communication process between the server and the air conditioner electric control air conditioning module is complex and slow, the transmitted data is complex, the communication bandwidth is occupied, and the response efficiency of the control operation is reduced.
One aspect of the embodiments of the present invention provides a remote air conditioner control method, in which a communication method between a server and an air conditioner electric control air conditioner module is set to change the original full-instruction communication transmission by changing the received information of a message body into single-instruction reception, so that some unnecessary information is deleted relatively, some control instructions are separated individually, and transmission of some unnecessary data is reduced. The time for the server to acquire the last data is reduced, and especially the time difference of control is greatly improved for the control of multiple devices.
Specifically, in the process of data transmission between the server and the air conditioning module, the request message body encapsulated by the previous air conditioning control command is processed as shown in fig. 1.
1. And independently issuing the state instruction.
Compared with the prior art that all state instructions are packed and issued together, the user adjustment state quantity in the state instructions is separately extracted and issued separately. The adjustment state quantity can be a temperature adjustment instruction, a wind speed adjustment instruction, an air conditioning mode adjustment instruction, an air conditioning switch instruction and the like.
In the splicing process, if the air conditioner is opened, only relevant starting instructions are spliced, other temperatures and modes do not need relevant instructions, relevant mutual exclusion logics are transferred to an electric control to be processed, an electric control device of the air conditioner is enabled to judge whether the instructions are mutually exclusive with the current running state of the air conditioner, if the instructions are in an automatic mode, so that mutual exclusion judgment at a server end is omitted, the local judgment is that all current running states of the air conditioner are stored in real time due to the electric control device of the air conditioner, and all running state data of the air conditioner are not needed when the judgment at the server end is carried out. Therefore, the mutual exclusion judgment is simpler, more efficient and more accurate. And the mutual exclusion operation controlled by the equipment is completely controlled electrically, the related development is simple and convenient, and each manufacturer does not need to additionally develop the same mutual exclusion judgment.
The splicing is an increasing process of instructions such as temperature and mode, and if only temperature is set, only temperature instructions are increased, and if only mode is set, only mode instructions are increased.
2. And in the process of parameter splicing by the server, corresponding splicing is only carried out on the independent data, and the spliced data is transmitted to the server.
And correspondingly splicing the data of the air conditioning module required by the server in the process of controlling the equipment by the user through the cloud server.

0100 is the packet count, and in order to prevent the risk of replay attack, the last server transmission and the next server transmission must be separated in a certain order.
bb00 is the synchronization header of the electrical control protocol, and the electrical control will only parse the synchronization header of bb00 protocol for handshaking of network data.
0c00 is a frame command 0c00 represents that this is a new frame command.
And 02 represents transparent transmission. The transparent transmission is direct transmission without any analysis.
0a00 is the total length of the protocol parsed from the small start, 000a, into 10 bytes.
0001 is representative of a home appliance type air conditioner.
0001 is a subtype hang-up under the representative home appliance.
00000001 is an air conditioner message body, and indicates that the issued control command is the query command of the message body.
32f5 is frame check inside the electronic control. The parameters from protocol synchronization to message are generated according to a certain rule.
337c is message check. The method for checking the message in the air-conditioning module encrypts all the bytes in the front through a certain algorithm to obtain the message check, and the air-conditioning module carries out related check according to the parameter.
The control instructions of the air conditioner are spliced in the message body, and corresponding splicing is carried out in the spliced temperature control message body according to the version number, the model identification, the multi-online ID group, the command type and the command data.
The temperature of the air conditioner is spliced in the command data, and the air conditioner message body occupies one byte and eight bits in one byte.
Where the first bit is 0. The second bit is a unit thermometer, 0 for Celsius and 1 for Fahrenheit. The 3 to 7 bytes represent the set temperature, where 00000 represents 8 degrees and 00001 represents 9 degrees, sequentially adding up. The last bit represents the half degree setting, 0 represents no half degree, and 1 represents a set half degree. And issuing the air conditioner to the electric control air conditioning module according to the design.
3. And issuing a control instruction to perform relevant control.
And issuing the related control command to the air conditioning module. And the air conditioning module carries out corresponding detection according to the issued message header, the total message length, the command type, the message count, the message body and the message inspection. Then the message body is taken out and sent to the electric control end to carry out corresponding processing. The electric control end carries out corresponding processing according to the acquired message body, and firstly carries out mutual exclusion judgment, and the mutual exclusion judgment carries out corresponding control without error.
Therefore, some unnecessary information is deleted in the communication, and some control commands are separated independently, so that the transmission of some unnecessary data is reduced. The time for the server to acquire the last data is reduced in the control process, and the time difference of control is greatly improved particularly for the control of multiple devices.
