Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
The following describes a lease clean drink machine unlocking method, a lease clean drink machine unlocking system and a lease clean drink machine unlocking server according to the embodiment of the invention with reference to the attached drawings.
As described above, since the user of the rental beverage dispenser is not a professional, the user may not operate properly during installation or use, which may cause a safety hazard during use of the rental beverage dispenser.
For example, in the process of installing the rental-type water purifier, the rental-type water purifier may leak electricity or water when providing services due to improper installation of the water inlet pipe or the power line.
For another example, the user may modify the rental beverage dispenser in a private manner during the process of installing the rental beverage dispenser, which may result in the rental beverage dispenser failing to serve normally and causing electric leakage.
In order to solve the problems, the invention provides an unlocking method of a leasing clean drink machine, which enables a user to lock the leasing clean drink machine after the installation of the leasing clean drink machine is finished, only basic operation functions such as power on and power off are provided, other operation functions are set to be in a locking state, and only after a server checks that the installation of the leasing clean drink machine is qualified, the related equipment can be unlocked and used by using a special device.
Fig. 1 is a flowchart of a rental beverage dispenser unlocking method according to one embodiment of the present invention.
As shown in fig. 1, the rental beverage dispenser unlocking method may include:
s101, the server receives an unlocking request sent by an unlocking application of the terminal equipment, analyzes unlocking request information and obtains a first equipment identifier of the rental clean drink machine to be unlocked.
The first device identifier may include information identifying uniqueness of the rental beverage dispenser, such as a Serial Number (SN), a production Number of the rental beverage dispenser, and a registration code of the rental beverage dispenser.
In practical application, in order to facilitate related technical personnel to perform unlocking operation control and the like on the rental beverage dispenser, an unlocking request key and the like can be provided in the unlocking application of the terminal device, so that a user can click the unlocking request key on the unlocking application to send an unlocking request to the server, wherein the unlocking request includes a first device identifier of the rental beverage dispenser in order to clarify the unlocking of the rental beverage dispenser to which the unlocking request is directed.
Specifically, after receiving an unlocking request sent by an unlocking application of the terminal device, the server analyzes the unlocking request information to obtain a first device identifier of the rental beverage dispenser to be unlocked, so as to identify the specific rental beverage dispenser for which the unlocking request is specific.
In different application scenarios, connection modes of the unlocking applications of the server and the terminal device are different, so that modes of sending the unlocking request to the server by the unlocking application of the terminal device are different, for example, when the connection modes of the unlocking applications of the server and the terminal device are WiFi connection, the unlocking application of the terminal device sends the unlocking request to the server through WiFi.
And S102, if the server detects that the first equipment identifier is stored, detecting whether the corresponding unlocking device is on line according to a second pre-stored equipment identifier corresponding to the first equipment identifier.
It can be understood that, in practical applications, the rental beverage dispenser that can be unlocked is the rental beverage dispenser that is already in the locked state, and is the rental beverage dispenser whose installation condition meets the corresponding specification, and when the rental beverage dispenser is already in the unlocked state, or the installation condition is not qualified, such as the installation of a power supply is unsafe, the unlocking process cannot be performed.
Therefore, in order to improve the unlocking accuracy, it is necessary to verify whether the rental beverage dispenser corresponding to the first device identifier is legal.
Specifically, the server stores the first device identifier of the legal rental clear drink machine, so that if the server detects that the first device identifier included in the unlocking request exists in the server, the server considers that the rental clear drink machine corresponding to the first device identifier included in the unlocking request is legal, and can unlock the rental clear drink machine.
According to the unlocking method of the lease water purifier, the lease water purifier is unlocked through the unlocking device, when the lease water purifier is determined to meet the installation condition, the unlocking device is connected with the lease water purifier through the related hardware interface and is connected with the server in a wireless mode, and the unlocking device achieves the information transparent transmission effect between the server and the lease water purifier.
For example, the unlocking device can be inserted into a hardware socket of the rental beverage dispenser through a connecting wire arranged outside, performs information interaction with the rental beverage dispenser through a UART serial port, and performs automatic connection with the server through a GPRS communication module.
Therefore, the server stores the second device identifier of the unlocking device corresponding to the first device identifier of the legal lease water purifier, after the first device identifier in the query request is detected to be stored in the server, in order to unlock the lease water purifier, the second device identifier of the unlocking device corresponding to the first device identifier is obtained, and whether the corresponding unlocking device is on-line or not is detected according to the second device identifier, wherein the second device identifier can comprise information which uniquely identifies the unlocking device, such as a CCID (serial number) code of the unlocking device.
It should be noted that, according to different specific application requirements, the manner of acquiring, by the server, the first device identifier of the rental beverage dispenser and the second device identifier corresponding to the first device identifier are different, which is exemplified as follows:
in a first implementation manner, the unlocking device is connected with the rental beverage dispenser after detecting that the rental beverage dispenser meets the preset installation condition, so that the server can actively acquire the second device identifier of the unlocking device and the first device identifier of the rental beverage dispenser connected with the unlocking device through the unlocking device.
In this example, the server initializes a communication interaction link with the unlocker and monitors whether the unlocker sends a connection request, and if the server monitors the connection request sent by the unlocker, the server establishes a connection with the unlocker.
And then, the server sends a device information query request to the unlocking device, receives a first device identifier of the connected rental clean drink machine fed back by the unlocking device and a second device identifier of the unlocking device, and stores the corresponding relation between the first device identifier and the second device identifier.
In a second implementation manner, since the unlocking device is connected to the rental beverage dispenser after detecting that the rental beverage dispenser satisfies the preset installation condition, the unlocking device can actively send the second device identifier of the unlocking device and the first device identifier of the rental beverage dispenser connected to the unlocking device to the server after the unlocking device is connected to the rental beverage dispenser.
In this example, the server initializes a communication interaction link with the unlocker and monitors whether the unlocker sends a connection request, and if the server monitors the connection request sent by the unlocker, the server establishes a connection with the unlocker.
And then, the server receives a first equipment identifier of the connected rental clean drink machine and a second equipment identifier of the unlocking device, which are sent by the unlocking device, and stores the corresponding relation between the first equipment identifier and the second equipment identifier.
S103, if the server detects that the unlocking device is on line, the server sends an unlocking instruction containing an unlocking code to the lease clean drink machine through the unlocking device.
Specifically, if the server detects that the unlocking device is on line, the server indicates that the current unlocking device can control the rental clean drink machine to perform unlocking operation, and therefore, an unlocking instruction containing an unlocking code is sent to the rental clean drink machine through the unlocking device, wherein the unlocking code comprises identification information which uniquely identifies the rental clean drink machine, such as a serial number of the rental clean drink machine to be unlocked.
And S104, the server receives unlocking information fed back by the unlocking device, indicating that the lease water purifier is successfully unlocked according to the unlocking code, and sending an unlocking success prompt message to the unlocking application of the terminal equipment.
In one embodiment of the invention, the lease water purifier verifies that the identification information is consistent with the identification information stored locally according to the identification information in the unlocking code, if so, the lease water purifier performs unlocking operation, and the unlocking information of successful unlocking is fed back to the server through the unlocking device.
In order to more visually display the unlocking result, the server receives unlocking information of successful unlocking of the lease water purifier according to the unlocking code fed back by the unlocking device and sends unlocking success prompt information to the unlocking application of the server, so that the server visually displays the current successful unlocking to the user.
In summary, in the rental beverage dispenser unlocking method according to the embodiment of the present invention, the server receives an unlocking request sent by an unlocking application of the terminal device, analyzes the unlocking request information to obtain a first device identifier of the rental beverage dispenser to be unlocked, if the server detects that the first device identifier is stored, the server detects whether a corresponding unlocking device is online according to a second device identifier corresponding to the first device identifier, which is prestored, and if the server detects that the unlocking device is online, the server sends an unlocking instruction including an unlocking code to the rental beverage dispenser through the unlocking device, and further, the server receives unlocking information, which is fed back by the unlocking device, of the rental beverage dispenser and is successfully unlocked according to the unlocking code, and sends an unlocking success prompt message to the unlocking application of the terminal device. Therefore, illegal installation and private refitting of the rental water purifier are effectively prevented, and the safety of the rental water purifier is improved.
Based on the above embodiments, it should be understood that, according to different application scenarios, the manner of detecting whether the corresponding unlocking device is online according to the pre-stored second device identifier corresponding to the first device identifier is different. For example, the status identifier of the unlocking device may be obtained, and whether the unlocking device is online or not may be determined according to the status identifier.
For a more clear description, how to detect whether the corresponding unlocking device is online according to a second device identifier corresponding to the first device identifier that is prestored, in the following description, a heartbeat signal is sent to the unlocking device through the server, and whether the unlocking device is online is determined according to a response condition of the unlocking device to the heartbeat signal, which is exemplified as follows:
fig. 2 is a flowchart of a method for unlocking a rental beverage dispenser according to another embodiment of the present invention, as shown in fig. 2, the method including:
s201, the server receives an unlocking request sent by an unlocking application of the terminal equipment, analyzes unlocking request information and obtains a first equipment identifier of the rental clean drink machine to be unlocked.
For example, when the server is connected with the unlocking application in a WiFi manner, the server may send an unlocking request to the unlocking application of the terminal device through WiFi, and analyze the first device identifier of the rental beverage dispenser to be unlocked in the unlocking request.
S202, if the server detects that the first equipment identification is stored, the server acquires a pre-stored second equipment identification corresponding to the first equipment identification, and sends a heartbeat signal to the unlocking device corresponding to the second equipment identification.
The heartbeat signal is a method for sending a small data packet to the other interconnected party at intervals and judging whether a communication link between the two interconnected parties is disconnected or not according to the reply condition of the other party.
In the embodiment of the invention, the server judges whether the connection between the unlocking device and the server is disconnected or not by a method of sending the heartbeat signal to the unlocking device corresponding to the second equipment identifier.
The method comprises the steps that when the unlocking device is in an off-line state, the link connection between the unlocking device and the server is stopped, and only when the unlocking device is on-line, the link connection between the unlocking device and the server can be maintained, so that whether the unlocking device is on-line or not can be judged by judging whether the connection between the unlocking device and the server is disconnected or not.
S203, if the server receives the heartbeat response signal fed back by the unlocking device within the preset time, the server knows that the unlocking device is on line.
Specifically, if the server receives the heartbeat response signal fed back by the unlocker within the preset time, it indicates that the communication link between the server and the unlocker is not disconnected, and thus it is known that the unlocker is online.
The preset time is the normal response time of the heartbeat signal calibrated according to a large number of experiments, and if the link connection of both communication parties is normal, one party sending the heartbeat signal receives the mental state response signal sent by the other party within the preset time.
And S204, sending an unlocking instruction containing an unlocking code to the rental clean drink machine through the unlocking device.
And S205, the server receives unlocking information of successful unlocking of the lease water purifier according to the unlocking code fed back by the unlocking device, and sends an unlocking success prompt message to the unlocking application of the terminal equipment.
For example, when the unlocking code includes a production number of the rental beverage dispenser, the rental beverage dispenser compares the received production number with a locally stored production number, and if the received production number is consistent with the locally stored production number, the rental beverage dispenser performs unlocking operation, and feeds back unlocking information of successful unlocking to the rental beverage dispenser through the unlocking device.
Therefore, the server receives unlocking information fed back by the unlocking device and indicating that the lease water purifier is successfully unlocked according to the unlocking code, and sends a message indicating that the lease water purifier is successfully unlocked to the unlocking application of the terminal equipment, so that successful unlocking can be visually shown to the user.
It should be noted that, in the specific execution process, the external environmental reasons, such as unstable connection signal between the current unlocking device and the server, or excessive current operating pressure of the server, may cause the rental clean drink machine to not receive the unlocking query request, or the server to not receive the unlocking information of successful unlocking fed back by the unlocking device.
Therefore, in an embodiment of the present invention, if the server does not receive the unlocking information of successful unlocking, which is fed back by the unlocking device, within the preset time, the server retransmits the unlocking instruction to the rental beverage dispenser through the unlocking device. Wherein the predetermined time is calibrated according to a number of experiments.
Furthermore, if the server detects that the sending times of the unlocking instruction meet the preset threshold, the server indicates the reason of current unlocking failure, which may be that the hardware connection between the unlocking device and the lease water purifier is in a problem, and the like, so that an unlocking overtime prompt message is sent to the unlocking application of the terminal device, and related personnel can conveniently perform troubleshooting and the like.
The preset threshold of the number of times is calibrated according to a large number of experiments, for example, the number of times can be 3.
And S206, if the server does not receive the heartbeat response signal fed back by the unlocking device within the preset time, the server knows that the unlocking device is off-line.
Specifically, if the server does not receive the heartbeat response signal fed back by the unlocker within the preset time, it indicates that the communication link between the server and the unlocker is disconnected, and thus knows that the unlocker is offline.
And S207, if the server detects that the unlocking device is offline, the server sends an unlocking device offline prompt message to the unlocking application of the terminal equipment.
Specifically, if the server detects that the unlocking device is offline, the server sends an unlocking offline prompt message to an unlocking application of the terminal device, so that the unlocking device can be conveniently unlocked and the like.
In summary, in the rental beverage dispenser unlocking method according to the embodiment of the present invention, the server sends the heartbeat signal to the unlocking device corresponding to the second identification device, and if the server receives the heartbeat response signal fed back by the unlocking device within the preset time, the server knows that the unlocking device is online, and if the server does not receive the heartbeat response signal fed back by the unlocking device within the preset time, the server learns that the unlocking device is offline. Therefore, whether the unlocking device is on line or not is accurately known, and the unlocking instruction is sent to the unlocking device when the unlocking device is in an on-line state, so that the unlocking efficiency of the rental clean drink machine is improved.
In order to implement the foregoing embodiment, the present invention further provides a server, and fig. 3 is a schematic structural diagram of a server according to an embodiment of the present invention, and as shown in fig. 3, the server includes: a receiving module 110, an obtaining module 120, a detecting module 130 and a sending module 140.

In order to implement the above embodiment, the present invention provides a rental beverage dispenser unlocking system, fig. 6 is a schematic structural diagram of the rental beverage dispenser unlocking system according to an embodiment of the present invention, and as shown in fig. 6, the rental beverage dispenser unlocking system includes a server 100, a rental beverage dispenser 200, an unlocking device 300, and an unlocking application 400 of a terminal device.
The description of the server 100 refers to the server described above with reference to fig. 3 to 5, and the implementation principle is similar, and is not described herein again.
In order to describe the workflow of the rental clear drink machine unlocking system more clearly in the embodiment of the present invention, the workflow of the rental clear drink machine is exemplified below with reference to a specific application scenario, in this example, a first device identifier of the rental clear drink machine is SN and a second device identifier of an unlocking device is CCID through information interaction between a server and the unlocking device by a TCP/IP protocol, which are described as follows:
in this example, as shown in fig. 7(a), the rental neat drink machine unlocking system includes a neat drink machine, an unlocker, a server, and an unlocking application.
Specifically, as shown in fig. 7(b), in the interaction between the server and the unlocking device, the server initializes the processing task of communicating with the unlocking device (S301), and after the initialization is completed, the server uses the TCP/IP protocol and listens to the corresponding communication port, and waits for the connection request of the unlocking device. After obtaining the connection request of the unlocker, the unlocker is connected to the server, and the server uses the TCP protocol to perform long connection of the unlocker and performs the sending of the heartbeat packet at an interval of 1 minute to confirm that the unlocker is in an online state (S302).
Meanwhile, the server sends a request for reading the CCID of the unlocking device to uniquely identify the unlocking device (S303), reads the SN code of the unlocking device connected to the clean drink machine and uniquely identifies the clean drink machine (S304), binds the CCID of the unlocking device and the SN code data of the clean drink machine after reading and stores the bound CCID and SN code data into a database so as to carry out matching search during subsequent unlocking. The function of the stored CCID is to search and determine the communication object by the device when communicating with the unlocking device, and the stored SN code is used to confirm whether the corresponding clear drink device exists in the database, so as to enhance the correctness of the unlocking (S305).
Further, in the interaction between the server and the unlock application as shown in fig. 7(c), the server needs to initialize the task-related resource for communicating with the unlock application (S401). After the initialization is completed, an HTTP request for unlocking the application terminal is monitored through a specific port, that is, in this example, the communication mode between the server and the unlocking application is an HTTP communication protocol, and after a connection request for unlocking the application is received, the server is connected to the unlocking device (S402).
Furthermore, the server monitors an unlocking request sent by the unlocking application after the server is successfully connected with the unlocking application (S403), and after the unlocking request sent by the unlocking application is received, the SN code of the clean drink machine to be unlocked is analyzed according to the unlocking request sent by the unlocking application, and the parameter is used for uniquely determining the clean drink machine object to be unlocked, so that other clean drink machines are prevented from being unlocked, and the system correctness is improved (S404).
The server uses the SN code to search whether the lease clean drink machine with the SN code is connected to the server (S405) or not in the database, if not, the information that the unlocking equipment does not exist is prompted to the APP terminal, and the safety of the system is improved. If the SN exists, the corresponding unlocking device is queried according to the CCID code of the unlocking device bound in the previous saving (S406), and meanwhile, before sending the unlocking command, it is first to confirm that the unlocking device is in an online state (S407), otherwise, a prompt message for unlocking the device offline is returned to the APP end.
And when the unlocking device is determined to be in an online state, an unlocking command is sent to the unlocking device (S408), and after the unlocking command is sent, the server waits for receiving unlocking information returned by the unlocking device and feeds the unlocking information back to the unlocking application terminal. If the information returned by the unlocking device is not received within 1 minute, the unlocking command is retransmitted, the retry is carried out for 3 times at most, and if the 3 times are not successful, the unlocking overtime information is sent to the unlocking application end for prompting (S409).
In summary, in the rental beverage dispenser unlocking system according to the embodiment of the present invention, the server receives an unlocking request sent by an unlocking application of the terminal device, analyzes the unlocking request information to obtain a first device identifier of the rental beverage dispenser to be unlocked, if the server detects that the first device identifier is stored, the server detects whether a corresponding unlocking device is online according to a second device identifier corresponding to the first device identifier, which is prestored, and if the unlocking device is online, the server sends an unlocking instruction including an unlocking code to the rental beverage dispenser through the unlocking device, and further, the server receives unlocking information, which is fed back by the unlocking device and is successfully unlocked according to the unlocking code, and sends an unlocking success prompt message to the unlocking application of the terminal device. Therefore, illegal installation and private refitting of the rental water purifier are effectively prevented, and the safety of the rental water purifier is improved.
