Detailed Description
For the purposes of making the objects, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present application based on the embodiments herein.
Referring to fig. 1, a schematic system architecture of a system for device control is shown in an embodiment of the present application.
The system for controlling the equipment comprises: user terminal 101, device 102, and server 103.
Wherein:
the user terminal 101 is configured to generate an offline service request, and send the offline service request to the device 102, where the offline service request includes offline verification data corresponding to the first offline code, and the offline service request is used to request the control device 102; before generating an offline service request, generating an online service request, and sending the online service request to the server 103, wherein the online service request carries a terminal identifier of the user terminal 101 and a device identifier of the device 102; the first offline code transmitted by the server 103 is received.
A device 102, configured to obtain an offline service request; the user terminal 101 is authenticated using the offline authentication data, and after the authentication is passed, control of the device 102 is performed.
A server 103 for online service request; a first offline code corresponding to the terminal identification and the device identification is generated and transmitted to the user terminal 101.
Based on the system for device control shown in fig. 1, the following describes a method for device control from the device side, the server side, and the user terminal side, respectively:
first, a method of controlling a device from a device side will be described, and as shown in fig. 2, the method may be applied to the device 102 shown in fig. 1, and the method may include the steps of:
step 201, obtaining an offline service request from a user terminal.
Alternatively, in this embodiment, when obtaining an offline service request from a user terminal, the method may be implemented in any one of the following manners:
in a first implementation manner, a lamplight flicker signal sent by a user terminal is detected and obtained, and an offline service request is extracted and obtained from the lamplight flicker signal.
In this implementation, a photosensitive element is mounted on the device, and the photosensitive element can capture a light flicker signal emitted by the user terminal.
When the offline service request is extracted from the lamplight flickering signals, firstly, a lamplight flickering curve corresponding to the lamplight flickering signals can be generated, secondly, lamplight flickering rules are determined according to the lamplight flickering curve, and finally, the service request corresponding to the lamplight flickering rules is used as the offline service request.
In practical application, the user terminal and the device can pre-agree on the mapping relation between the lamplight flickering rule and the service request.
In a second implementation manner, bluetooth data transmitted by the user terminal through bluetooth communication is received, and an offline service request is extracted from the bluetooth data.
In this implementation, bluetooth communication with the user terminal needs to be established in advance before the device receives the offline service request sent by the user terminal. Specifically, the device establishes a bluetooth communication connection with the user terminal according to a bluetooth request of the user terminal, and receives an offline service request sent by the user through the established bluetooth communication.
In a third implementation manner, an infrared signal sent by the user terminal is detected and obtained, and an offline service request is extracted from the infrared signal.
In this implementation manner, the device and the user terminal may agree in advance on a correspondence between the infrared signal and the service request, and after the device detects and obtains the infrared signal, obtain the offline service request from the infrared signal according to the agreed correspondence.
In this embodiment, the offline service request includes offline verification data corresponding to a first offline code, where the first offline code is associated with the device and the user terminal.
Step 202, verifying the user terminal by using the offline verification data, and executing control on the device after the verification is passed.
In this embodiment, the offline verification data may include a timestamp, a first verification code generated using a first offline code and the timestamp, and a terminal identifier of the user terminal.
In practical applications, the timestamp may be used to generate the current time of the first verification code, i.e. the first verification code is generated by using the current time and the first offline code.
In this embodiment, when generating the verification code, an alternative implementation may take a hash algorithm with the timestamp and the offline code to obtain the verification code. Thus, when generating the first verification code, a hashing algorithm may be taken on the timestamp and the first offline code to generate the first verification code.
Alternatively, the hashing algorithm includes, but is not limited to, the md5 algorithm.
Based on the offline verification data, the present embodiment provides two implementation manners for verifying the user terminal:
the first implementation, as shown in fig. 3, may specifically include the following steps:
step 301, judging whether a first identifier identical to the terminal identifier exists, if so, executing step 302.
The first identifier is a terminal identifier stored in the device.
When the illegal user only steals the terminal identification and fails to steal the first offline code and the timestamp, illegal control of the illegal user on the equipment can be avoided through matching of the terminal identification and the first identification.
Step 302, obtaining a receiving time for receiving the offline service request.
In order to avoid illegal control of the device caused by theft of the terminal identifier, after the first identifier identical to the terminal identifier exists in the verification device, the timestamp in the offline verification data is verified by continuously receiving the receiving time of the offline service request.
Step 303, determining a time difference between the time stamp and the receiving time.
Step 304, determining whether the time difference is not greater than a preset time threshold, if so, executing step 305.
Step 305, generating a second verification code corresponding to the second offline code and the timestamp.
The second offline code is an offline code corresponding to the first identifier stored in the device.
Step 306, determining whether the second verification code is the same as the first verification code, if yes, executing step 307.
In order to avoid that the terminal identification, the off-line code and the time stamp are stolen, the equipment is illegally controlled, and the first off-line code is also verified after the terminal identification and the time stamp are verified.
Step 307, control of the device is performed.
And when the first identifier which is the same as the terminal identifier does not exist, or the time difference is larger than a preset time threshold, or the second verification code is different from the first verification code, sending verification failure information to the user terminal.
In practical applications, the verification failure information may carry the reason of verification and identification, such as insufficient usage amount.
In this embodiment, the preset time threshold may be set according to an empirical value.
The embodiment realizes the process of verifying the offline service request of the user terminal when the first identifier and the second offline code are stored in the device.
A second implementation, as shown in fig. 4, may include the following steps:
step 401, obtaining a device identifier of a device.
Step 402, a third offline code corresponding to the terminal identifier and the device identifier is generated.
Alternatively, the third offline code may be generated by an offline code generation algorithm predetermined with the server.
In this embodiment, the offline code generation algorithm includes, but is not limited to, a random string generation algorithm, a hash algorithm, or the like.
In practice, the hashing algorithm includes, but is not limited to, the md5 algorithm.
Step 403, generating a third verification code corresponding to the third offline code and the timestamp.
Optionally, the algorithm for generating the third verification code is the same as the algorithm for generating the first verification code.
Step 404, when the third verification code is the same as the first verification code, performing control on the device.
The embodiment realizes the process of verifying the offline service request of the user terminal when the device and the server have an offline code generation algorithm in advance.
Optionally, performing control of the device may include performing a start-up service, i.e. after authentication of the user terminal with the offline authentication data is passed, the device performs the start-up service to complete the self-start.
In view of the fact that the device itself may not have a database and the processing power of the device itself is limited, the server may be further requested to re-verify the usage amount of the device after the device performs the start-up service.
Optionally, the device may send a verification request to the server for verifying whether the usage amount of the user terminal is lower than a preset amount, where the verification request includes a terminal identifier; and receiving a shutdown instruction sent by the server after verifying that the usage amount is lower than the preset amount, and executing shutdown service according to the shutdown instruction.
In practical applications, the usage amount may be a balance of an account corresponding to the terminal identifier.
In this embodiment, the device may further delete the terminal identifier and the first offline code according to a deletion instruction sent by the server.
According to the technical scheme provided by the embodiment, the device can receive the offline service request of the user terminal, and execute control on the device, such as control device self-starting, after the user terminal is verified by the offline service request. Thus, even if the user terminal cannot be networked, the user terminal can request to turn on the device based on the offline service request.
The description of the method of device control on the device side is thus completed.
Next, a method of controlling a device from a server side will be described, as shown in fig. 5, which may be applied to the server 103 shown in fig. 1, and may include the steps of:
step 501, an online service request from a user terminal is received.
The online service request carries the terminal identifier and the equipment identifier of the user terminal.
In practical application, the server may receive the online service request through communication modes such as 4G network, WIFI, etc.
Step 502, a first offline code corresponding to the terminal identifier and the device identifier is generated, and the first offline code is sent to the user terminal.
In this embodiment, the first offline code may be generated based on an offline code generation algorithm.
In this embodiment, the offline code generation algorithm includes, but is not limited to, a random string generation algorithm, a hash algorithm, or the like.
Alternatively, the online service request may also be used to request control (e.g., start) of the device corresponding to the device identification, and thus, after receiving the online service request from the user terminal, a control (e.g., start) instruction may also be sent to the device to control (e.g., start) the device.
Optionally, before the server sends the start instruction to the device based on the online service request, the server may further verify the usage amount corresponding to the terminal identifier, and determine that the usage amount is not less than the preset amount.
Optionally, the server may further verify the usage amount of the user terminal based on the verification request alone, specifically, the server receives the verification request to verify the usage amount corresponding to the terminal identifier, and when the usage amount is lower than a preset amount, sends a shutdown instruction to the device, where the verification request includes the terminal identifier.
Alternatively, in order to reduce the risk of stolen use of the offline code, a measure may be to update the offline code stored in the server at regular intervals. Specifically, before the first offline code is generated, whether a historical offline code corresponding to the terminal identifier and the device identifier is stored or not may be judged, if yes, the survival time of the historical offline code is obtained, and the first offline code is generated when the survival time is determined to be longer than the preset time.
Alternatively, in another measure, considering that the user terminal may not request updating of the first offline code for a long time, the server may forcedly delete the first offline code at a fixed time, specifically, after generating the first offline code, the server obtains a storage duration of the first offline code, and when the storage duration is longer than a preset storage duration, sends a deletion instruction to the device, and deletes the first offline code, where the deletion instruction is used to instruct deletion of the terminal identifier and the first offline code.
Wherein the preset storage duration is not less than the preset survival duration.
In practical application, the preset storage duration and the preset generation duration can be preset by a user.
The description of the method of device control on the server side is thus completed.
Finally, the method for controlling the device from the user terminal side is described, as shown in fig. 6, and may be applied to the user terminal 101 shown in fig. 1, where the method may include the following steps:
step 601, an offline service request is generated.
Step 602, sending an offline service request to a device.
The offline service request comprises offline verification data corresponding to the first offline code, and the offline service request is used for requesting the control device.
Alternatively, the offline verification data may include a timestamp, a first verification code generated using the first offline code and the timestamp, and a terminal identification of the user terminal.
Correspondingly, when the service request is generated, a time stamp and a first offline code are acquired, the first verification code is generated by adopting the time stamp and the first offline code, and the offline server request is further generated according to the time stamp, the first offline code and the first verification code.
Alternatively, the user terminal may request allocation of the first offline code to the server through the online service request before generating the offline service request. Specifically, the user terminal generates an online service request carrying a terminal identifier and a device identifier, sends the online service request to the server, and receives a first offline code sent by the server.
In practical application, the user terminal may send an online service request to the server through communication modes such as a 4G network, WIFI, and the like.
