According to an embodiment of the present application, there is provided a method of acquiring information of an appliance.
Fig. 1 is a flowchart of a method for acquiring information of an electrical appliance according to an embodiment of the present application. As shown in fig. 1, the method comprises the steps of:
step S101, when detecting that the target remote controller receives the target key instruction, generating a request data frame based on the target key instruction.
In the above, an embodiment of the present application provides a remote controller, where the keys arranged on the remote controller include keys capable of acquiring information of an air conditioner, in addition to a conventional key used daily to control an operation mode of the air conditioner, and the key capable of acquiring the information of the air conditioner is referred to as a target key.
When the target key is pressed, a target key instruction is generated, and a request data frame for requesting the electric appliance information from the target electric appliance is generated according to the key instruction.
The target electric appliances referred to in this application include electric fans, air conditioners, televisions, and the like equipped with a remote controller. The present embodiment is described by taking an air conditioner as an example.
And step S102, sending the request data frame to the target electric appliance.
Specifically, after the request data frame is generated, the remote controller sends the request data frame to the air conditioner in an infrared mode so as to make an information request to the air conditioner.
It should be noted that, the remote controller may use other wireless communication methods besides infrared communication to communicate with the air conditioner, such as bluetooth, wi-fi, etc., and the specific communication method may be different, but the transmission principle is basically the same.
And step S103, identifying the request data frame, and calling the information of the target electrical appliance according to the identified result.
When the air conditioner receives the request data frame, the air conditioner calls the information of the corresponding air conditioner according to the request data frame, and generates a feedback data frame according to the information of the air conditioner, wherein the feedback data frame includes information of a unit of the air conditioner or information of an operator of the air conditioner.
It should be noted that the information of the air conditioner included in the feedback data frame is not limited to the information of the air conditioner group and the information of the operator, and may be the content of the specification of the air conditioner, etc., but all the information about the air conditioner that can be displayed in text may be called by the request data frame.
And step S104, generating a target graphic code according to the information of the target electrical appliance.
As described above, after the requested information of the target electrical appliance is called, the information of the target electrical appliance is converted into a graphic code, preferably, the graphic code is a two-dimensional code.
Optionally, when it is detected that the target remote controller receives the target key instruction, generating the request data frame based on the target key instruction includes: judging the attribute of the target key instruction, wherein the attribute is divided into a first attribute and a second attribute; if the attribute of the target key instruction is the first attribute, the generated request data frame contains key information; and if the attribute of the target key instruction is the second attribute, the generated request data frame comprises key information and verification information.
Specifically, the remote controller receives a key instruction from a user and determines the attribute (type) of the key instruction, and if the key instruction is a key requiring authentication information, the user may be required to input corresponding authentication information. And then the remote controller generates a data frame containing key information and verification information according to the key type of the user or generates a data frame only containing the key information, and sends the data frame to the air conditioner in an infrared mode.
Fig. 2 is a schematic diagram of a remote controller in an embodiment provided in the present application, where the remote controller includes several keys of "acquire two-dimensional code", "engineering parameter", "debug", and "query fault", and these keys are target keys in the present application. As shown in the remote controller in fig. 2, the "acquire two-dimensional code" is any key that can be used by a user using the air conditioner, and the user can correspondingly send a request data frame containing key information to the air conditioner by pressing the "acquire two-dimensional code" key, so that the attribute of the "acquire two-dimensional code" key is the first attribute.
Correspondingly, the keys of the engineering parameter, the debugging key and the fault inquiry key are keys used by professionals in maintenance operation such as maintenance of the air conditioner, verification information needs to be input in the using process of the keys for verification, and misoperation of non-professional users is avoided.
Optionally, after generating the target graphic code according to the information of the target electrical appliance, the method further includes: displaying the graphic code on the target remote controller; and/or displaying the graphic code on the target appliance.
Specifically, after the requested information is generated according to the information of the air conditioner, in an alternative method, a graphic code is displayed on a display screen of a remote controller for requesting the information of the air conditioner.
In another optional method, the generated graphic code is displayed on a display screen of the air conditioner, the graphic code displayed on the air conditioner can be used for a user to acquire air conditioner data requested by a remote controller through code scanning, and when the user is far away from the air conditioner and is inconvenient to scan the code to acquire air conditioner information, the graphic code can be simultaneously displayed on the remote controller through the request of the remote controller so that the user can acquire the air conditioner information.
Optionally, after sending the request data frame to the target appliance, the method further includes: verifying the request data frame, wherein the verification comprises verifying the integrity and the correctness of the request data frame; if the requested data frame does not pass the verification, controlling the target electrical appliance to send a retransmission request to the target remote controller, wherein the retransmission request is a retransmission data frame, and the frame header of the retransmission data frame is used for representing the attribute of the retransmission data frame; and in a first preset time after the control target electric appliance sends the retransmission request, after detecting that the target electric appliance receives the first byte of the request data frame, the control target electric appliance stops sending the retransmission request.
Specifically, the present embodiment provides a data error retransmission mechanism, and after receiving a data frame from a remote controller, the air conditioner first needs to verify the integrity and correctness of the data. If the verification is not passed and the air conditioner fails to receive the request data frame, the air conditioner sends a retransmission request to the remote controller.
Furthermore, the retransmission request uses a retransmission frame, which uses a frame header flag different from that of the data frame, and both communication parties transmit the retransmission request only when the data frame reception fails, in order to ensure that the communication order is not disturbed.
After the remote controller receives the retransmission request, the first byte of the last data frame needs to be sent within a preset time, otherwise, the air conditioner sends the retransmission request again until the requested data frame is successfully received or the retransmission request is tried for n times. The mechanism mainly aims to solve the problem that infrared communication is easily interfered by various factors to cause data errors or transmission interruption, and improves the success rate of communication.
The air conditioner verifies the request data frame, including verifying the integrity and correctness of the request data frame, and mainly aims to emphasize that infrared communication is easy to break and lose part of data, and data is easy to generate errors due to interference. So, here, the correctness verification method written as one frame data can be taken as an example: the header of each frame starts with fixed pilot data (e.g., the beginning of a frame must be 0xAA, 0xAA), and when the receiver receives the fixed pilot data, it starts to store the data received later. When receiving information of the frame head, firstly judging whether each information of the frame head is in an effective range, such as that the frame length information in the frame head cannot exceed the defined maximum frame length, if so, discarding the frame data and recapturing the fixed guide data 0xAA, 0xAA of the frame head. If the frame head passes the verification, receiving the data with the length specified by the frame length information, if the data exceeds the length, discarding the excess part, if the data is shorter than the specified length, considering the data is lost. After receiving one frame, the CRC check is also needed to verify the correctness of one frame data. (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, after sending the request data frame to the target appliance, the method further includes: controlling the target electrical appliance to return a feedback data frame according to the request data frame, wherein after the target electrical appliance receives the request data frame, the target electrical appliance analyzes the request data frame and generates a feedback data frame according to an analysis result, and the feedback data frame comprises information of the target electrical appliance; and the control target remote controller receives the feedback data frame and generates a graphic code according to the feedback data frame.
Specifically, in the method for displaying the graphic code on the display screen of the remote controller, after the air conditioner successfully receives the request data frame, a feedback data frame needs to be returned according to the request data frame, and the requested information of the air conditioner is displayed on the display screen of the remote controller according to the feedback data frame.
Specifically, after the air conditioner receives the request data frame which successfully passes the verification, the air conditioner analyzes the request data frame, analyzes the key information in the request data frame, and calls the information of the air conditioner according to the key information.
For example, if the analyzed key information is the key information of the "engineering parameter", the engineering parameter information of the air conditioner unit, such as the temperature information of each thermal bulb, the related information of the compressor, the opening degree of the electronic expansion valve, etc., is retrieved.
Specifically, the called information of the air conditioner is generated into a feedback data frame, and the feedback data frame is returned to the remote controller. And after the air conditioner successfully receives the feedback data frame, the remote controller generates a graphic code according to the air conditioner information contained in the feedback data frame and displays the graphic code on a display screen of the remote controller.
It should be noted that, in the technical scheme of displaying the graphic code on the air conditioner, the air conditioner does not need to return a feedback data frame to the remote controller according to the request data frame, but directly displays the graphic code containing the air conditioner information on the display screen of the air conditioner according to the request of the request data frame.
Optionally, after the control target appliance returns the feedback data frame according to the request data frame, the method further includes: detecting whether a target remote controller receives a retransmission request within a second preset time, wherein the retransmission request is a request sent under the condition that a request data frame does not pass the verification of a target electric appliance, the retransmission request is a retransmission data frame, and a frame header of the retransmission data frame is used for representing the attribute of the retransmission data frame; when detecting that the target remote controller receives the retransmission request, controlling the target remote controller to send the request data frame to the target electric appliance again; when detecting that the target remote controller displays the graphic code, controlling the target remote controller to stop sending the request data frame to the target electrical appliance; or when the target electric appliance is detected to display the data transmission failure information, controlling the target remote controller to stop sending the request data frame to the target remote controller.
Specifically, in the present embodiment, a timeout retransmission mechanism is provided, which is implemented as follows: after the remote controller sends a request data frame to the air conditioner, the air conditioner must reply within a predetermined time (whether or not the request data frame is valid). The implementation mode is as follows: after the remote controller sends the request data frame to the air conditioner, the remote controller must receive the reply of the air conditioner within the preset time, if the remote controller does not receive the reply, the remote controller can send the request data frame again until the remote controller receives the successful feedback data frame or tries for n times, if the final result fails, the remote controller can display failure information on a screen, and the situation that the user does not know when the remote controller loses data can be effectively avoided through the mechanism, and the user experience is improved.
Further, the retransmission request uses a retransmission data frame, which uses a different frame header flag than the data frame, in order to ensure that the communication order is not disturbed.
Under the same condition, when the air conditioner fails to receive the request data frame, the air conditioner sends a retransmission request to the remote controller, after the remote controller receives the retransmission request, the remote controller needs to send the first byte of the last data frame within a preset time, otherwise, the air conditioner sends the retransmission request again until receiving the data or trying for n times. The mechanism mainly aims to solve the problem that infrared communication is easily interfered by various factors to cause data errors or transmission interruption, and improves the success rate of communication.
Optionally, the controlling the target remote controller to receive the feedback data frame, and generating the graphic code according to the feedback data frame includes: controlling the target remote controller to analyze the feedback data frame and acquiring the information of the target electrical appliance contained in the feedback data frame; judging whether the type of the first information is consistent with that of the second information, wherein the first information is information of a target electrical appliance analyzed by the feedback data frame, and the second information is information of the target electrical appliance corresponding to the target key; and if the type of the first information is consistent with that of the second information, converting the information of the target electrical appliance contained in the data frame into a graphic code.
Specifically, after the remote controller receives a feedback data frame fed back by the air conditioner, the remote controller determines the type of the information of the air conditioner included in the feedback data frame.
As described above, as the target keys provided on the remote controller in fig. 2, the information of the air conditioner corresponding to each key is different, for example: the information of the air conditioner corresponding to the key for acquiring the two-dimensional code is set information, and is mainly information for identifying the identity of the set, such as an MAC address/a bar code, and the like, so that the type of the information of the air conditioner corresponding to the key for acquiring the two-dimensional code is mainly address information and the like, and therefore when the information contained in the feedback data frame received by the remote controller is an address character string, the attribute contained in the feedback data frame can be judged to be consistent with the type of the information corresponding to the key for acquiring the two-dimensional code, and the feedback data frame can be received and processed.
On the contrary, if the information contained in the received feedback data frame is information such as parameters, which is different from the type of information corresponding to the "obtaining two-dimensional code", the remote controller may determine that the type of the information corresponding to the key is different from the type of the information corresponding to the "obtaining two-dimensional code" (in the case that the feedback data frame is interfered, the information in the feedback data frame may be replaced), may refuse to receive the feedback data frame, and send a retransmission data frame to the target air conditioner, and request the target air conditioner to retransmit the feedback data frame.
It should be noted that, as shown in fig. 2, fig. 2 is a schematic diagram of a remote controller provided in an embodiment of the present application, where the remote controller includes several keys for "acquiring a two-dimensional code", engineering parameters, debugging, and querying a fault, and the several keys are target keys in the present application. As shown in the remote controller in fig. 2, the "acquiring two-dimensional code" is any key that can be used by a user using an air conditioner, and is used for correspondingly acquiring unit information of the air conditioner, mainly including information for identifying the identity of a unit, such as an MAC address/barcode.
Correspondingly, the information correspondingly taken by the 'engineering parameter' key is the engineering parameter information of the air conditioner unit, such as the temperature information of each temperature sensing bulb, the related information of the compressor, the opening degree of the electronic expansion valve and the like.
Correspondingly, the information that the 'debugging' key corresponds to and is called is the unit information that needs to be used when the air conditioner is debugged, such as the inner unit engineering number, the inner unit capacity and the like.
Correspondingly, the information called by the 'inquiry fault' key is mainly the current fault information of the unit, and the information can provide corresponding guidance for air conditioner maintenance personnel.
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; sending the request data frame to the target electrical appliance; identifying the request data frame, and calling the information of the target electrical appliance according to the identified result; the target graphic code is generated according to the information of the target electrical appliance, the problem that the information of the air conditioner cannot be acquired at any time due to the fact that the paper two-dimensional code is easy to be stained and damaged and difficult to store because the service life of the air conditioner is long when the information of the air conditioner is stored in the paper two-dimensional code in the related technology 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 different than presented herein.
