Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer and more complete, the technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention, and based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the scope of the present invention.
As described in the background art, in the prior art, most of the smart vending machines adopt a polling method based on an HTTPS protocol, that is, the smart vending machines need to send query requests regularly to poll and acquire control commands, the control platform cannot actively push the control commands to the smart vending machines, and for HTTPS, HTTPS connection needs to be reestablished for each message, which may cause significant overhead, and automatic recovery may not be performed when a connection is disconnected, resulting in poor stability.
For the intelligent vending machine, the control instruction is sent according to the user requirement, and the control instruction is not sent to the intelligent vending machine all the time, so that the polling mechanism is inevitably adopted, the power consumption is increased, and the resource consumption is increased. However, the mode of sending the control instruction only when the user needs the mode is in accordance with a publish/subscribe mechanism, so that the connection between the mobile terminal and the intelligent vending machine can be established by adopting an MQTT protocol based on publish/subscribe; meanwhile, in order to improve the safety of the control instruction in the transmission process, a fixed secret key is not adopted, and a one-secret random secret key determination mode is adopted.
The foregoing is the concept provided by the present invention, and specific implementations of the concept provided by the present invention are described below.
As shown in fig. 1, an embodiment of the present invention provides a method for controlling an intelligent vending machine, which is applied to a control platform, and the method may include the following steps:
step 101: receiving a control request of a user for the intelligent vending machine; the control request comprises control information of the intelligent vending machine;
step 102: randomly determining a secret key of the intelligent vending machine according to a one-machine one-secret mechanism; wherein, different intelligent vending machines conforming to one machine and one secret mechanism correspond to different secret keys;
step 103: encrypting the control information of the intelligent vending machine according to the secret key to obtain a control instruction for controlling the intelligent vending machine;
step 104: acquiring MQTT key information corresponding to the intelligent vending machine; the system comprises a control platform, a server and a plurality of intelligent vending machines, wherein MQTT key information used for realizing MQTT communication connection between the intelligent vending machines and the server is stored in the control platform, and different intelligent vending machines correspond to different MQTT key information;
step 105: sending the MQTT key information to the intelligent vending machine so as to enable the intelligent vending machine to establish MQTT communication connection with the server;
step 106: and sending control instructions to the server to enable the intelligent vending machine to receive the control instructions based on the MQTT communication connection.
According to the intelligent vending machine control method provided by the embodiment of the invention, after the control information of the user on the intelligent vending machine is received, the key of the intelligent vending machine is randomly determined according to a one-machine one-secret mechanism, the control information is encrypted by using the key to obtain the encrypted control instruction, and the control instruction is sent to the server connected with the intelligent vending machine, so that the intelligent vending machine receives the control instruction. The intelligent vending machine establishes MQTT communication connection with the server according to the MQTT key information which is acquired from the control platform and corresponds to the intelligent vending machine. Therefore, the control information is encrypted by the key randomly determined by the one-machine one-secret mechanism, and the control information can be prevented from being maliciously tampered after being intercepted due to the randomness of the key, so that the safety of the MQTT message pushing mechanism is ensured, the control information can be reliably and efficiently transmitted to the intelligent vending machine through the MQTT protocol, and the use experience of a user is improved. Meanwhile, through MQTT communication connection, a subscription mechanism between the intelligent vending machine and the server can be established, so that the control instruction is sent to the intelligent vending machine based on the subscription mechanism when the server receives the control instruction, thereby realizing publish/subscribe message transmission, ensuring that the transmission of the control instruction is more reliable and simpler, being beneficial to the intelligent vending machine to receive the control instruction immediately, and further improving the use experience of users.
It should be noted that MQTT (message queue telemetry transport) is a message protocol based on a publish/subscribe paradigm under the ISO standard. It works on the TCP/IP suite, a publish/subscribe messaging protocol designed for remote devices with poor hardware performance and in case of poor network conditions, for which it requires a messaging middleware, i.e. a server.
In the embodiment of the invention, the intelligent vending machine and the server communicate based on the MQTT protocol, so that the communication cost is very low, the heavy cost caused by reestablishing HTTPS connection for each new request message is avoided, the tolerance to an unstable network is higher, and the automatic recovery from the faults such as disconnection can be realized, but the HTTPS needs the client to retry encoding to reestablish the connection, so that the connection mode in the embodiment is more stable. Meanwhile, the operation cost of the MQTT is relatively low, the simplicity of the MQTT is beneficial to realizing the MQTT on an additional client with little effort, one-to-many message issuing can be provided, application program coupling is released, remote control is realized, and therefore better use experience can be brought to users.
In the embodiment of the present invention, step 102 is based on a one-secret mechanism, which can ensure that different smart vendors connected to the control platform correspond to different secret keys. Specifically, after the smart vending machine is powered on, a communication connection based on an HTTPS protocol may be established with the control platform, and based on the communication connection, a randomly generated one-secret key may be sent to the smart vending machine. Therefore, different from the prior art that one type of intelligent vending machine corresponds to the same secret key, the method can generate one secret dynamic secret key for the intelligent vending machine, each intelligent vending machine has the unique secret key, the safety of the secret key is improved, the control information is encrypted through the secret key, and the safety of the control information in the transmission process is further improved.
It should be noted that the validity period of the key is the whole process from powering on the smart vending machine to powering off the smart vending machine, that is, the whole process of connecting the smart vending machine and the control platform.
Optionally, on the basis of the method for controlling a smart vending machine shown in fig. 1, after determining the key of the smart vending machine according to a one-secret mechanism in step 102, before acquiring MQTT key information of the corresponding smart vending machine in step 104, further comprising:
sending an MQTT registration request to a server; the MQTT registration request is used for establishing MQTT communication connection between the intelligent vending machine and the server;
receiving registration success information returned by the server according to the MQTT registration request; the information of successful registration comprises MQTT key information corresponding to the intelligent vending machine;
acquiring configuration information corresponding to the intelligent vending machine;
and correspondingly storing the configuration information of the intelligent vending machine and the MQTT key information.
In the embodiment of the invention, for the intelligent vending machine which is powered on for the first time, after the corresponding key is obtained according to a one-machine one-secret mechanism, the MQTT registration request is firstly sent to the server, and after the successful registration information including the MQTT key information returned by the server according to the MQTT registration request is received, the MQTT key information and the obtained configuration information corresponding to the intelligent vending machine are correspondingly stored. Therefore, when the intelligent vending machine is powered on again subsequently, after the corresponding dynamic key is obtained according to the one-machine one-secret mechanism, the MQTT registration request does not need to be repeated, the step 104 can be directly executed to obtain the corresponding MQTT key information and the corresponding configuration information, the response time is prolonged, and the use experience of the user can be improved.
Specifically, identification information contained in the intelligent vending machine is acquired, and an MQTT registration request is sent to the server through a Connect message carrying the identification information of the intelligent vending machine. Therefore, the server identifies the intelligent vending machine through the identification information to generate unique MQTT key information corresponding to the intelligent vending machine, and connection between the intelligent vending machine and the server is established.
It should be noted that the configuration information includes, but is not limited to, basic configuration information such as heartbeat time and status of the smart vending machine.
Optionally, on the basis of the intelligent vending machine control method shown in fig. 1, after acquiring MQTT key information of the corresponding intelligent vending machine in step 104, before sending a control instruction to the server in step 106, the method further includes:
sending the configuration information to the intelligent vending machine;
receiving current state information returned by the intelligent vending machine according to the configuration information; the current state information comprises the state of MQTT communication connection established between the intelligent vending machine and the server;
judging whether the MQTT communication connection state is an offline state;
if so, returning offline state information to the intelligent vending machine so that the intelligent vending machine establishes MQTT communication connection with the server;
if not, returning the on-line state information to the intelligent vending machine, and receiving the current state information returned by the intelligent vending machine according to the configuration information.
In the embodiment of the invention, in order to avoid the situation that the control instruction after the MQTT communication connection is offline cannot be issued to the intelligent vending machine, the state of the MQTT communication connection can be detected in real time through an HTTPS protocol, so that when the MQTT communication connection is in an offline state, feedback is timely made to the intelligent vending machine, and the intelligent vending machine can reestablish the MQTT communication connection with the server. In particular, the amount of the solvent to be used,

It should be noted that, in the embodiment of the present invention, the intelligent vending machine and the control platform establish a communication connection through an HTTPS protocol, where MQTT key information, configuration information, current state information, and returned offline state information and online state information are transmitted based on the HTTPS protocol. Therefore, an offline mechanism can be constructed based on the HTTPS protocol, the MQTT protocol is only used for transmitting the control command, the state of MQTT communication connection can be monitored in real time through the division and cooperation of the two protocols, and the MQTT communication connection is reestablished in time when the MQTT communication connection is in an offline state, so that the instant and reliable transmission of the control command is ensured, and the use experience of a user is improved.
In the embodiment of the present invention, the step 106 of sending the control command to the server is implemented by calling an interface of the server.

sending the key to the smart vending machine; the intelligent vending machine is used for decrypting the control command through the key so that the intelligent vending machine operates according to the control information included in the decrypted control command.
In the embodiment of the present invention, in order to ensure that the smart vending machine can acquire the control information in the encrypted control instruction, it is necessary to send the randomly acquired key to the smart vending machine through the HTTPS protocol, so that the smart vending machine decrypts the control instruction according to the key to acquire the control information, so as to operate according to the control information.
In the embodiment of the invention, after the intelligent vending machine operates according to the control information, a control result is returned in real time according to the heartbeat time included in the configuration information, wherein the control result is used for representing the state of the intelligent vending machine after the intelligent vending machine completes the operation of the control information, so that the control platform can monitor the state of the intelligent vending machine in real time and remotely.
