Description

Technical Field

[0001] The invention relates to the technical field of water controllers, in particular to an off-line consumption system of water controllers based on Bluetooth communication. Background Art

[0002] In the water controller consumption system with Bluetooth communication, system anomalies, system maintenance, network anomalies, etc. are inevitable. For the water controller terminal with real-time communication, normal consumption cannot be achieved when the system is abnormal; in addition, normal consumption cannot be achieved when the 4G / 5G signal is abnormal, the user terminal traffic exceeds the limit and the network is disconnected. Summary of the invention

[0003] In order to overcome the above problems existing in the prior art, the present invention provides a water controller offline consumption system based on Bluetooth communication, which adopts the following technical solutions:

[0004] A water controller offline consumption system based on Bluetooth communication includes: a business platform, an IOT platform, a user terminal, and a water controller terminal; wherein the business platform and the IOT platform communicate via Ethernet to achieve data interaction and instruction transmission; the IOT platform and the user terminal are connected via a wireless communication network to establish a remote communication channel; the user terminal and the water controller terminal communicate via Bluetooth to achieve close-range data interaction.

[0005] Furthermore, in the case of online consumption, the business platform sends the password book to the water controller terminal through the IOT platform, and regularly updates the password book of the water controller terminal.

[0006] Furthermore, in the case of online consumption, the workflow of the business platform, IOT platform, user terminal, and water controller terminal is as follows:

[0007] The user terminal initiates a valve opening request to the IOT platform through the wireless communication network, and the IOT platform forwards the valve opening request to the business platform;

[0008] The business platform verifies the legitimacy of the user terminal account information. When the account information is determined to be legitimate, the business platform issues a valve opening instruction carrying dynamic encryption information;

[0009] The valve opening command is sent to the water controller terminal via the IOT platform and user terminal;

[0010] The water controller terminal receives the valve opening instruction, uses the local code book of the water controller terminal to decode the valve opening instruction, and then opens the valve for consumption.

[0011] Furthermore, in the case of online consumption, the business platform sends the password book to the user terminal through the IOT platform, and the user terminal stores the password book.

[0012] Furthermore, in the case of online consumption, the business platform sends the device authentication information of the water controller terminal that the user terminal has used to the user terminal through the IOT platform. The user terminal caches the device authentication information sent by the platform, wherein the device authentication information has an offline authentication validity period, and the offline authentication validity period is controlled by the business platform parameters.

[0013] Furthermore, in the case of offline consumption, after the offline authentication validity period exceeds the set offline usage time, the user terminal directly prompts that the offline time has exceeded the limit, and the user terminal cannot initiate a valve opening instruction.

[0014] Furthermore, in the case of offline consumption, the workflow of the business platform, IOT platform, user terminal, and water controller terminal is as follows:

[0015] The user terminal initiates a valve opening request to the IOT platform through the wireless communication network. When the IOT platform does not respond to the valve opening request of the user terminal, the user terminal enters the offline operation mode;

[0016] The user terminal establishes a Bluetooth communication connection with the water controller terminal;

[0017] Based on the device code of the water controller terminal, the user terminal generates dynamic encryption information through the cached device authentication information of the water controller terminal corresponding to the device code;

[0018] The user terminal simulates the business platform to send a valve opening instruction carrying dynamic encryption information to the water controller terminal;

[0019] The water controller terminal receives the valve opening instruction, and decodes the valve opening instruction according to the locally stored code book. After the water controller terminal successfully decodes the instruction, the valve is opened for consumption.

[0020] Furthermore, offline consumption situations include: abnormalities in the business platform and IOT platform, or upgrades and maintenance of the business platform and IOT platform, or abnormalities in the user terminal network.

[0021] Furthermore, in the case of offline consumption, the user terminal cannot pass the authentication for the water controller terminal that has not been used, that is, the user terminal cannot establish Bluetooth communication with the water controller terminal.

[0022] Furthermore, when the offline consumption system of the water controller based on Bluetooth communication resumes normal online consumption, the water controller terminal uploads the consumption record to the business platform for deduction during online consumption.

[0023] The present invention has the following beneficial effects:

[0024] The present application provides a water controller offline consumption system based on Bluetooth communication, including a business platform, an IOT platform, a user terminal, and a water controller terminal; wherein the business platform and the IOT platform communicate via Ethernet to achieve data interaction and instruction transmission; the IOT platform and the user terminal are connected via a wireless communication network to establish a remote communication channel; the user terminal and the water controller terminal communicate via Bluetooth to achieve close-range data interaction. The water controller offline consumption system based on Bluetooth communication provided by the present application achieves normal use of the water controller terminal in the event of system abnormalities and user terminal network abnormalities, and at the same time provides a complete encryption mechanism to prevent illegal users from using it, thereby improving the security and integrity of the system and achieving user-free use in the event of system abnormalities and user terminal network abnormalities.
