Fig. 1 is a flowchart of a method for acquiring information of an electric appliance according to an embodiment of the present application. As shown in fig. 1, the method comprises the steps of:
step S101, when a request instruction is received by a target electric appliance, generating a feedback instruction, wherein the request instruction is used for requesting information of the target electric appliance, and the feedback instruction comprises the information of the target electric appliance.
Above, the electric appliances referred to in the present application refer to all electric appliances in the home life, wherein the electric appliances include a washing machine, an electric fan, an air conditioner, a microwave oven refrigerator, and the like.
In the embodiment of the present application, an air conditioner is taken as an example for explanation.
In the foregoing, in the embodiment of the present application, a remote controller or a mobile terminal application is provided, where a key set provided on the remote controller includes a key capable of acquiring information of an air conditioner in addition to a conventional key for controlling an operation mode of the air conditioner used in daily life.
When a key for acquiring the air conditioner of the remote controller or a key for acquiring the air conditioner in an application program of a terminal is pressed, the air conditioner receives a request instruction for acquiring the information of the air conditioner and generates a feedback instruction according to the request instruction.
Step S102, analyzing the feedback instruction, and converting the analyzed information into a target graphic code.
Specifically, based on the feedback instruction returned by the air conditioner, the information contained in the feedback instruction is analyzed and converted to generate the graphic code, and it should be noted that the graphic code herein is all the graphic codes which can contain the information of the air conditioner, preferably two-dimensional codes.
Step S103, displaying the target graphic code on the target remote controller.
Specifically, the generated two-dimensional code may be displayed on a remote controller or in an application of the terminal.
Optionally, before the feedback instruction is generated when the target electrical appliance is detected to receive the request instruction, the method further comprises: calling information of a target electric appliance; converting information of the target electric appliance into a target graphic code, wherein the information of the target electric appliance is at least one of the following: the method comprises the steps of generating unit information of a target electric appliance, operating parameter information of the target electric appliance and operator information of the target electric appliance; and displaying the target graphic code on a display screen of the target electrical appliance and/or a display screen of the wire controller.
Optionally, after parsing the feedback instruction and converting the parsed information into the target graphic code, the method further includes: and displaying the target graphic code on a display screen of the target terminal.
Specifically, two methods are provided in the embodiments of the present application, one is that a paper two-dimensional code is attached to an air conditioner for a user to scan to obtain information of the air conditioner, and the two-dimensional code is a fixed two-dimensional code, which includes operator information of the air conditioner and some hardware information of the air conditioner.
The other is to display the obtained two-dimension code of the air conditioner on the display screen of the air conditioner in the form of a dynamic two-dimension code, wherein the two-dimension code comprises the information of an air conditioner operator and the information of real-time operation parameters of an air conditioner unit, so that the two-dimension code is a dynamic two-dimension code, and the two-dimension code can also comprise the information of operation faults of the air conditioner.
It should be noted that, the dynamic two-dimensional code of the air conditioner may be displayed on a line controller of the air conditioner in addition to the display screen of the air conditioner.
Optionally, before the feedback instruction is generated when the target electrical appliance is detected to receive the request instruction, the method further comprises: when the target remote controller is detected to receive the target key instruction, generating a request instruction based on the target key instruction; and sending the request instruction to the target electric appliance.
Above-mentioned ground, when detecting that the air conditioner received the request instruction, at first discern the button type of sending the instruction, the button type on the remote controller is divided into multiple, and fig. 2 is the schematic diagram of a remote controller in this application in the embodiment that provides, and the remote controller includes "acquire two-dimensional code", "engineering parameter", "debugging", "inquiry trouble" several buttons, and these several buttons are the target button in this application.
As shown in the remote controller in fig. 2, the "acquire two-dimensional code" is a key that can be used by any user who uses the air conditioner, and by pressing the "acquire two-dimensional code" key, the user can correspondingly send a request instruction containing key information to the air conditioner, where the information of the air conditioner requested by the request instruction includes operation parameter information of the air conditioner, operator information of the air conditioner, and unit hardware information of the air conditioner.
Correspondingly, the information of the request corresponding to the engineering parameter key is engineering parameter information of the air conditioner unit, such as temperature information of each temperature sensing bulb, related information of a compressor, opening of an electronic expansion valve and the like.
Correspondingly, the information of the corresponding request of the debugging key is the unit information such as the number of the internal machine, the capacity of the internal machine and the like which are required to be used when the unit debugging is carried out on the air conditioner.
Correspondingly, the information of the request corresponding to the 'query fault' key is mainly the fault information of the unit currently occurring, and the information can provide corresponding guidance for air conditioner maintenance personnel.
Further, based on the different request instruction of each key, the generated request instruction is sent to the air conditioner.
It should be noted that, if the air conditioner receives a request instruction of the terminal application, because of different request keys included in the terminal application, a request instruction for requesting different information is also generated.
Optionally, before sending the request instruction to the target appliance, the method further comprises: analyzing the request instruction to obtain a request data frame contained in the request instruction; verifying the request data frame, wherein the verification comprises verification of the integrity and the correctness of the request data frame; if the request data frame does not pass the verification, a retransmission request is sent to the target remote controller, wherein the retransmission request is a first retransmission data frame, and the frame head of the first retransmission data frame is used for representing the attribute of the first retransmission data frame; and stopping sending the retransmission request to the target remote controller when the target appliance is detected to successfully receive the request command.
Specifically, the present embodiment provides a data error retransmission mechanism, when an air conditioner receives a request command from a remote controller or a terminal application, the air conditioner parses the request command and obtains a data frame included in the request command, and first needs to verify the integrity and correctness of the data frame. If the verification is not passed, the air conditioner fails to receive the request data frame, and the air conditioner sends a retransmission request to the remote controller or the terminal application.
Further, the retransmission request uses a retransmission frame, which uses a different frame header flag from the data frame, so that both communication parties can transmit the retransmission request only when the reception of the data frame fails, in order to ensure that the communication order is not disordered.
After the remote controller or the terminal application receives the retransmission request, the first byte of the last data frame needs to be sent within a preset time, otherwise, the remote controller or the terminal application can send the retransmission request again until the air conditioner is detected to successfully receive the request data frame or try n times. The mechanism mainly aims to solve the problem that the infrared communication is easy to be interfered by various factors to cause data errors or transmission interruption, and improves the communication success rate.
The air conditioner verifies the requested data frame, including verifying the integrity and correctness of the requested data frame, mainly aims to emphasize that the infrared communication is easily broken to lose part of data, and is also easily interfered to cause data errors. The manner of verifying the correctness of one frame of data can be written here as an example: the frame header of each frame starts with fixed pilot data (e.g., a frame must begin with 0xaa,0 xaa) and when the receiver receives these fixed pilot data, it starts to save the data received later. When receiving frame header information, firstly judging whether each information of the frame header is in an effective range, for example, the frame length information in the frame header cannot exceed the defined maximum frame length, if the information exceeds the effective range, discarding the frame data and recapturing the frame header fixed guide data 0xAA,0xAA. If the frame header passes the verification, receiving data with the specified length of the frame length information, discarding the excess part if the data exceeds the specified length, and considering that the data is lost if the data is shorter than the specified length. After receiving a frame, the correctness of the data of the frame needs to be verified through CRC. (if the frame type is a data frame and the length is lost or the CRC check fails, the receiver needs to send a retransmission request.)
Optionally, analyzing the feedback instruction and converting the analyzed information into the target graphic code further includes: analyzing the feedback instruction and obtaining the information of the target electric appliance; verifying the integrity of the information of the target electric appliance; and if the information of the target electric appliance is complete, converting the information of the target electric appliance into a target graphic code and displaying the target graphic code on the target remote controller.
Specifically, after the air conditioner feeds back the information of the air conditioner to generate a feedback instruction, the feedback instruction is firstly analyzed to obtain a feedback data frame, the feedback data frame comprises information of the request air conditioner, the technical means adopted for verifying the information of the air conditioner is to verify the integrity of the feedback data frame, and if all character strings in the feedback data frame are complete, the obtained information is indicated to be not interfered. Conversely, if the received feedback data frame is detected to contain incomplete character strings, the received data frame is considered to be incomplete, and the data is partially lost due to interference of other signals received in the transmission process.
Optionally, after parsing the feedback instruction and obtaining the information of the target electrical appliance, the method further includes: verifying the integrity of the information of the target electric appliance; if the information of the target electric appliance is incomplete, retransmitting a request instruction to the target electric appliance; based on the resent request instruction, receiving a feedback instruction returned by the target electric appliance based on the request instruction again.
Specifically, when the feedback command fails the integrity verification, the feedback data frame is refused to be received, and the retransmission data frame is sent to the target air conditioner, so that the target air conditioner is required to retransmit the feedback data frame.
The retransmission mechanism here is identical to the retransmission mechanism described above and will not be described here again.
According to the method for acquiring the information of the electric appliance, when the target remote controller is detected to receive the target key instruction, a request data frame is generated based on the target key instruction; transmitting the request data frame to the target electric appliance; identifying the request data frame, and calling the information of the target electric appliance according to the identified result; according to the information of the target electric appliance, a target graphic code is generated, the problem that the information of the air conditioner cannot be acquired at any time because the information of the air conditioner is stored in the paper two-dimensional code in the related art is solved, and the paper two-dimensional code is easy to pollute and destroy and difficult to store because the service life of the air conditioner is long is solved, and the technical effect of monitoring the state and the information of the air conditioner at any time is achieved.
It should be noted that the steps illustrated in the flowcharts of the figures may be performed in a computer system such as a set of computer executable instructions, and that although a logical order is illustrated in the flowcharts, in some cases the steps illustrated or described may be performed in an order other than that illustrated herein.
