[0052] Figure 1 is a flow chart of a preferred embodiment of the instruction interaction method of the smart device of the present application;

[0053] Figure 2 is a schematic diagram of the principle of communication interaction of each end in a preferred embodiment of the instruction interaction system of the smart device of the present application. DETAILED DESCRIPTION

[0054] In order to make the purpose, technical scheme and advantages of the present application more clear and definite, the present application will be further described in detail below with reference to the drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present application, and are not used to limit the present application.

[0055] The instruction interaction method of the smart device according to the preferred embodiment of the present application, as shown in Figure 1 and Figure 2 , the instruction interaction method of the smart device comprises the following steps:

[0056] Step S10, the platform issues batch instructions to the instruction cache server, and waits for the smart device to connect to the MQTT server.

[0057] Specifically, the platform (i.e. business system) establishes a connection with the instruction cache server (a cache system specially used for storing and quickly providing computer program instructions (codes), aiming to optimize the access speed of instructions and reduce the waiting time of processors or computing units, the instruction cache server optimizes the execution efficiency of computationally intensive tasks by centralizing and caching code instructions, and is especially suitable for modern computing architectures with distribution and high concurrency), the platform issues batch instructions to the instruction cache server; the instruction cache server caches the batch instructions issued by the platform to ensure that the instructions are not lost, and waits for the smart device to connect to the MQTT server (MQTT Broker is the core component of the lightweight Internet of Things communication protocol MQTT (Message Queuing Telemetry Transport), responsible for receiving, forwarding and scheduling messages between devices (clients), and realizes an efficient, low-power publish / subscribe (Pub / Sub) communication mode), the MQTT server is the "central nerve" of Internet of Things communication, decoupling the dependence between devices through the publish / subscribe mode, and taking into account low power consumption and high real-time performance.

[0058] Step S20, when the first smart device is connected to the MQTT server, the MQTT server notifies the instruction cache server and the platform of the first connection result.

[0059] Specifically, the first smart device connects to the MQTT server through the MQTT protocol, the MQTT protocol (Message Queuing Telemetry Transport) is a lightweight and efficient publish / subscribe (Pub / Sub) message transmission protocol specially designed for the Internet of Things (IoT) and low-bandwidth environments, which is based on TCP / IP and suitable for communication scenarios between devices with low power consumption, high latency or unreliable networks, the MQTT protocol has become a de facto standard for Internet of Things communication due to its lightweight, efficient and flexible nature, and sets QoS (Quality of Service) to zero to reduce power consumption, QoS0 is the best effort delivery, which does not guarantee message delivery, when the MQTT client publishes with QoS1, the MQTT broker does not confirm receipt, and the message is not stored and re-sent by the sender, QoS0 is usually referred to as "fire and forget", which provides the same guarantee as the underlying TCP protocol; then generate the first connection result; the MQTT server establishes a connection with the instruction cache server, the MQTT server notifies the instruction cache server of the first connection result, and the instruction cache server forwards it to the platform.

[0060] Step S30, the instruction cache server sends instructions to the MQTT server according to the priority, the MQTT server forwards to the first smart device, and the first smart device executes the instructions sent by the MQTT server.

[0061] Specifically, the instruction cache server sends instructions to the MQTT server according to the priority; the MQTT server forwards the instructions sent by the instruction cache server to the first smart device; the first smart device executes the instructions sent by the MQTT server to generate the execution result corresponding to the instructions, and each instruction execution will have a corresponding execution result.

[0062] Step S40, the first smart device sends the execution result after executing the instructions to the MQTT server, and the MQTT server sends the execution result to the instruction cache server.

[0063] Specifically, the first smart device sends the execution result after executing the instructions to the MQTT server, and the execution result includes execution success and execution failure; the MQTT server sends the execution result of execution success or execution failure to the instruction cache server, and if the first smart device reply timeout or reply failure, the next instruction is sent. The instruction execution result is recorded to the MySQL database (a widely used open source relational database management system) to realize persistent storage.

[0064] Step S50, the second smart device is connected with the MQTT server, the MQTT server notifies the instruction cache server and the platform of the second connection result, and the instruction cache server sends instructions to the MQTT server according to the priority until all instructions are sent.

[0065] Specifically, the second smart device is connected with the MQTT server through the MQTT protocol, sets the QoS to zero, generates the second connection result; the MQTT server notifies the instruction cache server of the second connection result, and the instruction cache server forwards to the platform; the instruction cache server sends instructions to the MQTT server according to the priority, continues to execute the instructions according to the process of the first smart device executing the instructions until all instructions are sent.

[0066] The first smart device and the second smart device are indirectly connected with the platform in one machine and one secret mode to ensure data security.

[0067] The time effectiveness of the instructions is set, and the instructions are effective within the valid period, for example, the remote unlocking instruction is valid for 3 minutes.

[0068] The platform sends a clear all cache instruction to the instruction cache server, and the instruction cache server clears all cached instructions of the smart device according to the clear all cache instruction, that is, the platform can issue a clear all cache instruction to the instruction cache server, and the part of the instruction is not executed on the smart device, such as all the instruction caches of the smart device before the user binds the smart device are cleared, to ensure that the smart device is restored to execute the binding after leaving the factory, so as to prevent historical data from causing interference.

[0069] The smart device is woken up daily for receiving instructions, and the completeness of the instructions is supplemented; after the platform issues an instruction, the instruction is stored in the instruction cache server, but has a time limit, for example, the instruction of issuing a password is valid within 24 hours, the smart device can be manually woken up to quickly receive relevant instructions, but can also wait for the smart device to be woken up at a regular time, such as woken up once every 8 hours to receive instructions, to prevent the loss of instructions due to invalidation.

[0070] For example, the first smart device or the second smart device waits for a preset time, and if the first smart device or the second smart device does not receive an instruction within the preset time, the first smart device or the second smart device enters a sleep state.

[0071] The smart device executes active connection to the server through a specific panel instruction, such as #5555, pulls the server instruction, and compensates the completeness of the data (the data is the result after the instruction is executed, for example, the device platform has 5 password records, and only 4 are locked on the surface, and the missing data is supplemented by synchronizing with the platform data).

[0072] The smart device reports relevant time directly into the RabbmitMQ queue, RabbmitMQ is a kind of message middleware, which is a container for storing messages, and the device reports time is not fixed, in order to ensure that the reported data will not be lost, so it is stored in this middleware first, and then the related business is executed, such as reporting the opening event, and storing it in the database table of the opening and closing record, the server asynchronously executes the business logic, such instruction cannot be responded in time, and the final response result can be known only after the smart device executes and reports, so as to reduce the waiting of the device and prolong the service life of the battery.

[0073] In the present application, the instruction cache server stores user instructions through caching, and when the smart device is woken up next time, the corresponding operation of the server instruction is executed, a compromise point between power consumption and real-time performance is selected, which can ensure that the instruction is not lost, without maintaining a long connection, and can also reduce the power consumption of the smart device and prolong the service life of the battery.

[0074] The technical effects that can be brought by the present application are as follows:

[0075] (1) Reduce power consumption: cache user instructions, and execute the specific operation process of the instructions when the smart device is woken up, which realizes the core mechanism of reducing power consumption, and ensures that the device can still effectively receive and execute instructions in a low-power state.

[0076] (2) Application of MQTT protocol: the MQTT protocol adopted between the smart device and the MQTT server, including the setting of QoS value, ensures that the device can still receive instructions in a low-power mode.

[0077] (3) Device wake-up strategy: the smart device wakes up regularly to receive MQTT server instructions, which helps to reduce overall power consumption.

[0078] (4) Security and data integrity: one-to-one encryption connection method and security measures for platform connection to ensure data integrity and security during instruction issuance and device response process.

[0079] Further, as shown in Figure 2 Based on the above instruction interaction method of the smart device, the present application also correspondingly provides an instruction interaction system of a smart device, wherein the instruction interaction system of the smart device comprises: a smart device, an MQTT server, an instruction cache server and a platform, the smart device comprises a first smart device and a second smart device, the platform and the instruction cache server are connected, the instruction cache server is connected with the MQTT server, and the MQTT server is connected with the first smart device and the second smart device.

[0080] The interaction process between each device is as follows:

[0081] 1. The platform issues batch instructions to the instruction cache server;

[0082] 2. The instruction cache server caches the batch instructions issued by the platform, and waits for the smart device to connect to the MQTT server;

[0083] 3. The first smart device connects to the MQTT server through the MQTT protocol;

[0084] 4. The MQTT server notifies the instruction cache server and the platform of the first connection result;
