Detailed Description
In order to make the objects, technical solutions and effects of the present invention clearer and clearer, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Example one
The control method of the air conditioner provided by the invention can be executed by the air conditioner, and the processor in the air conditioner can realize the control method of the air conditioner provided by the invention when executing the computer program.
An embodiment of a method for controlling an air conditioner according to the present invention is shown in fig. 1, and includes the steps of:
s110, when the control authority request signal is received, the air conditioner generates first data used for determining whether the control authority request signal is sent by the communication module according to a preset algorithm, and the first data is sent to the communication module through the communication interface, so that the communication module generates third data according to the first data and returns the third data to the air conditioner.
Specifically, the communication module may be disposed inside the air conditioner as a component of the air conditioner, or may be externally connected to the air conditioner as an independently disposed device, the communication between the communication module and the air conditioner is actually performed with a processor of the air conditioner, and the control permission request signal is received by the air conditioner through a communication interface that communicates with the communication module, specifically, the operation mode of the existing shared air conditioner is as follows: in the operation process of the shared air conditioner, a user can send instructions of renting, stopping or controlling the air conditioner and the like through a control application of the shared air conditioner, an operation platform receives the instructions sent by the user through the control application and then forwards corresponding instructions to the air conditioner through a communication module, the air conditioner performs operations such as opening, closing, temperature adjustment and the like according to the corresponding instructions, the communication module can be an NB-IOT (narrow-band Internet of things) module and communicates with the operation platform based on a frequency band provided by an operator, packages provided by the operator at present are charged according to fixed times/year or fixed flow/year, therefore, based on the consideration of operation cost, the interaction between the communication module and the operation platform cannot be too frequent, otherwise, the operation cost is greatly increased, and the communication module has a long empty window period in the operation process of the air conditioner, that is to say, the frequency of the communication module being called by the operation platform to communicate with the air conditioner is not high, but the communication module and the air conditioner are in serial communication, that is, the communication module and the air conditioner communicate with each other through a communication interface without depending on a frequency band provided by an operator, as shown in fig. 2, the communication module sends control data to a processor of the air conditioner, and the processor of the air conditioner returns response data. In the present application, the communication module sends a control authority request signal to the air conditioner, and when the air conditioner receives the control authority request signal, generating first data according to a preset algorithm, sending the first data out through a communication interface for communicating with the communication module, if the communication with the air conditioner is a legal communication module, third data is generated according to the first data through a preset algorithm and is sent back to the air conditioner, after the first data is sent out by the air conditioner, if the fourth data received by the communication interface of the communication module is consistent with the third data, the control authority request signal is sent by the communication module, the object of communication with the air conditioner through the interface is a legal communication module and data transmission between the communication module and the air conditioner is normal, so that the air conditioner can operate according to the control signal received from the communication interface of the communication module.
And when the control authority request signal is received, the processor of the air conditioner generates first data according to a preset algorithm. The control authority request signal is received by a processor of the air conditioner through a communication interface for communicating with the communication module, specifically, a communication data format with the communication module is agreed in advance, for example, the data format may be "header code + data type + data content + check", and for different data types, different codes are set, and when the air conditioner receives the signal, whether the signal is the control authority request signal is determined according to the data type in the data included in the signal. Specifically, as shown in fig. 3, in order to ensure that the air conditioner is not stolen, the communication module may not send a control permission request signal to the air conditioner after receiving the control signal of the operation platform, but may send the control permission request signal through the communication interface with the air conditioner at intervals of a preset time, such as 3min, so that the air conditioner may determine in real time whether the current object to be communicated is a legal communication interface. In a possible implementation manner, the communication module may also send an inquiry signal to the air conditioner to inquire the current operating state of the air conditioner at intervals of shorter time, such as 1s, for example, whether the air conditioner is in use, whether there is a fault, and the like, update the use state of the air conditioner in real time, and return related data to the operation platform when the operation platform requests the operating state of the air conditioner. Since the query signal is only used for querying and does not relate to control, the air conditioner may directly feed back the current operation state after receiving the query signal, as shown in fig. 3.
Specifically, the air conditioner generates first data for determining whether the control authority request signal is sent by the communication module according to a preset algorithm, and the method comprises the following steps:
s111, generating a first random number and a second random number by the air conditioner, and acquiring first encrypted data corresponding to the first random number according to a preset corresponding relation;
s112, the air conditioner carries out encryption operation on the first encrypted data through a first preset encryption algorithm to generate second encrypted data;
s113, the air conditioner arranges the first encrypted data and the second random number according to a first preset rule to obtain first data.
After receiving the control authority request signal, the air conditioner randomly generates two data, which are a first random number and a second random number, respectively, where the first random number and the second random number may be numbers, letters, or other codes, and the corresponding relationship between the random numbers and the data is preset, for example, a character string may be preset as a key, and each character and the random number are respectively corresponding according to a serial number of each character of the character string, such as: the first digit of the string is assigned the number 1, etc. And after the first random number and the second random number are generated, acquiring data corresponding to the first random number according to a preset corresponding relation to be used as first encrypted data.
In this embodiment, a first preset encryption algorithm is preset, and the first preset encryption algorithm may be an operation expression defined by a developer, for example, the first preset encryption algorithm is (X is data to be encrypted): x a1+42, (X +34) a2, (X A3) -15. After the first encrypted data are obtained, the air conditioner operates the first encrypted data according to a first preset encryption algorithm to generate second encrypted data, and then the second encrypted data and a second random number are arranged according to a first preset rule to obtain the first data.
Specifically, the first preset rule is an arrangement rule, after the second encrypted data is obtained, the second encrypted data and the second random number are combined according to a preset combination order of the encrypted data and the random number (for example, the order of the encrypted data before, the random number after, or the order of the encrypted data before, the random number after, and the random number before) to form a new character string, and then characters in the new character string are rearranged according to the first preset rule, for example, for the character string ABCDEF, the character string ABCDEF is rearranged into facded, and the like.
After the first data is generated, the first data is sent to the communication module through the communication interface with the communication module, and after the communication module receives the first data, the third data is generated according to the first data and is returned to the air conditioner, which will be specifically described in embodiment two.
Referring to fig. 1 again, the method for controlling an air conditioner according to the present embodiment further includes the steps of:
and S120, the air conditioner receives the fourth data through the communication interface, and determines whether the control authority request signal is sent out by the communication module by judging whether the fourth data is consistent with the third data.
The fourth data is data received by the air conditioner through a communication interface of the communication module after the first data is sent out, the third data is data generated by the legal communication module according to the first data, if the fourth data is consistent with the third data, the fourth data is generated by the legal communication module, namely, the object currently communicating with the air conditioner through the communication interface is a legal communication module, and the control authority request signal is sent out by the communication module.
Specifically, the air conditioner determines whether the control authority request signal is sent by the communication module by judging whether the fourth data is consistent with the third data, including:
s121, carrying out encryption operation on the first encrypted data through a second preset encryption algorithm to generate second data;
s122, rearranging the fourth data according to a second preset rule by the air conditioner to obtain third encrypted data;
and S123, when the third encrypted data is consistent with the second data, the air conditioner determines that the fourth data is consistent with the third data, and the control authority request signal is sent by the communication module.
In this embodiment, a second preset encryption algorithm is also preset, and the second preset encryption algorithm may be an operation expression defined by a developer, for example, the second preset encryption algorithm is (X is data to be encrypted): x +25+ a1, X a2+41, X6. And for first encrypted data generated in the process of generating the first data, performing encryption operation by using a second preset encryption algorithm to generate second data.
And after receiving the fourth data, the air conditioner rearranges the fourth data according to the second preset rule to obtain a new character string, extracts third encrypted data from the new character string obtained by rearranging the fourth data according to a combination mode of the random number and the encrypted data, and determines whether the third encrypted data is consistent with the second data. Specifically, in this embodiment, after the air conditioner sends the first data, if the legal communication module receives the first data, the air conditioner may calculate to obtain third data according to the first data, and the encrypted data obtained by the communication module after the third data generated according to the first data is rearranged according to the second preset rule process is consistent with the second data, so that the air conditioner may determine whether an object currently communicating through the communication interface with the communication module is a legal communication module by determining whether the third encrypted data obtained by rearranging the fourth data is consistent with the second data. The process of the communication module calculating the third data according to the first data will be specifically described in the second embodiment.
After determining whether the fourth data is consistent with the third data, the air conditioner executes different programs according to a result of whether the fourth data is consistent with the third data, as shown in fig. 3, which specifically includes:
and S130, if the fourth data is consistent with the third data, the air conditioner sends a request success signal to the communication module through the communication interface, and the air conditioner is controlled to operate according to a control signal received from the communication interface within a first preset time period.
If the fourth data is consistent with the third data, it is indicated that a current communication object of the air conditioner is corresponding to a legal communication module, the air conditioner sends a request success signal to the communication module, a processor of the air conditioner controls the air conditioner to operate according to a control signal received from a communication interface of the communication module within a first preset time, after the communication module receives the request success signal, the communication module does not send a control authority request signal within the first preset time, and sends the control authority request signal again after the first preset time, so that the air conditioner determines the legality of the communication module again according to the control authority request signal, and safe and stable communication is established between the air conditioner and the communication module.
And if the fourth data is inconsistent with the third data, the air conditioner sends a request failure signal through a communication interface of the communication module.
Therefore, in this embodiment, if the fourth data is inconsistent with the third data, the air conditioner sends a request failure signal through a communication interface with the communication module, so that the communication module may resend the control permission request signal after receiving the request failure signal when the current communication object is a legal communication module.
And if the frequency of the air conditioner continuously sending the request failure signal exceeds the preset frequency or the control authority request signal is not received within a second preset time after the request failure signal is sent through the communication interface, executing a shutdown program by the air conditioner.
The preset times can be 3 times, 5 times and the like, the number of times that the air conditioner continuously sends the request failure signal exceeds the preset times, or the control authority request signal is not received within a second preset time after the request failure signal is sent through the communication interface, it is indicated that the current communication object is not a legal communication module or the communication between the current communication object and the communication module fails, at this moment, the air conditioner executes a shutdown program, and the situation that the communication module fails to control the authority request and the air conditioner is directly shut down due to the fact that data packet loss is caused by the preset times can be prevented.
Example two
In an embodiment of the present invention, a method for requesting control authority of an air conditioner is further provided, where the method is executed by a communication module, and specifically, as shown in fig. 4, an embodiment of the method for controlling an air conditioner provided by the present invention includes the steps of:
s210, after the communication module sends the permission request signal to the air conditioner, first data returned by the air conditioner according to the control permission request signal is received.
Specifically, the communication module sends an authority request signal every a first preset time through a communication interface with the air conditioner, and after the air conditioner receives the authority request signal, the first data is generated and sent out through the communication interface, and the communication module receives the first data through the communication interface, which is specifically described in the first embodiment.
And S220, the communication module generates third data according to the first data through a preset algorithm, and then sends the third data to the air conditioner.
In order to verify the validity of the communication module, after receiving the first data, the communication module generates third data according to a preset algorithm, and the third data is sent to the air conditioner through the communication interface, so that the air conditioner can verify the validity of the communication module according to the third data.
Specifically, the communication module generates third data according to the first data through a preset algorithm, including:
and S221, after the first data are rearranged according to a third preset rule to obtain fourth encrypted data, carrying out decryption operation on the fourth encrypted data through a first preset decryption algorithm to obtain first decrypted data.
S222, carrying out encryption operation on the first decrypted data through a second preset encryption algorithm to obtain fifth encrypted data;
and S223, generating a third random number, and arranging the third random number and the fifth encrypted data according to a fourth preset rule to obtain third data.
The third preset rule corresponds to the first preset rule in the first embodiment, for example, if the first preset rule is to rearrange the character string ABCDEF into facbod, the third preset rule should be: for the character string ABCDEF, the character string is rearranged to bdfea, that is, for the character string X, the character string obtained by rearranging according to the first preset rule is identical to the character string obtained by rearranging according to the third preset rule. It can be seen that the new character string obtained by rearranging the first data according to the third preset rule by the communication module is the same as the character string obtained by combining the second encrypted data and the second random number by the air conditioner in the first embodiment, and the fourth encrypted data is extracted from the character string according to the preset combination order of the encrypted data and the random number, obviously, the fifth encrypted data should be the same as the first encrypted data in the first embodiment.
The first preset decryption algorithm corresponds to the first preset encryption algorithm, that is, for the data X, the decryption operation is performed according to the first preset decryption algorithm after the operation of the first preset encryption algorithm, and the data X can be obtained again. The first decrypted data obtained by the communication module performing decryption operation on the fourth encrypted data through the first preset decryption algorithm is the same as the first encrypted data in the embodiment. And then, the fifth encrypted data obtained by performing encryption operation on the first decrypted data by using a second preset encryption algorithm is the same as the second encrypted data in the embodiment.
After receiving the first data, the communication module generates a third random number, arranges the third random number and the fifth encrypted data according to a fourth preset rule to obtain third data, and specifically, combines the third random number and the fifth encrypted data according to a preset combination rule of encrypted data and random numbers and then rearranges the third random number and the fifth encrypted data according to the fourth preset rule. The fourth preset rule corresponds to the second preset rule in the first embodiment, for example, if the fourth preset rule is to rearrange the character string ABCDEF into facbod, the second preset rule should be: for the character string ABCDEF, the character string is rearranged to bdfea, that is, for the character string X, the character string obtained by rearranging according to the fourth preset rule is identical to the character string obtained by rearranging according to the second preset rule.
As is apparent from the above description of the process of generating the third data, the encrypted data obtained by rearranging the third data generated by the communication module according to the second preset rule should be the same as the second data in the first embodiment, so that the air conditioner can determine whether the communication object is the communication module according to whether the data received after sending the first data is the same as the third data.
Referring to fig. 4 again, the method for requesting control authority of an air conditioner according to the present embodiment further includes:
and S300, the communication module receives a control authority confirmation signal returned by the air conditioner.
Specifically, if the control authority confirmation signal returned by the air conditioner is the request success signal, it indicates that the communication between the communication module and the air conditioner is normal, and the validity of the communication module has been verified by the air conditioner, the communication module may normally issue a control instruction to the air conditioner, and no longer send a control authority request signal within the first preset time, and send a control authority request signal again after the interval of the first preset time.
If the control authority confirmation signal returned by the air conditioner is a request failure signal, the communication between the communication module and the air conditioner is abnormal, for example, faults such as packet loss, data dislocation and the like exist, and the communication module sends out the control authority request signal again to know that the request success signal is received.
In summary, the present invention provides a control method of an air conditioner and a control authority requesting method of an air conditioner, in which when an authority requesting signal is received by an air conditioner, a pre-agreed algorithm generates encrypted first data, the first data is used to be sent to a communication module to generate third data according to the pre-agreed pre-established algorithm, after the first data is sent out by the air conditioner through a communication interface communicating with the communication module, if fourth data received through the communication interface is identical to the third data, it is indicated that the communication module communicating with the air conditioner is a legal communication module, and the air conditioner can operate according to a control signal received by the communication interface.
