Description

TECHNICAL FIELD

[0001] The present application relates to the field of Bluetooth water control technology, in particular to a double-offline transaction authentication method and system of a Bluetooth water control system, especially for the special working condition that the Bluetooth terminal and the background service are offline at the same time, that is, double-offline, a reliable and safe authentication method is provided to ensure the integrity and legality of transaction data. BACKGROUND

[0002] At present, intelligent water control management systems based on wireless communication have been widely used in campus shower, direct drinking water and other scenes. Such systems usually use 4G, Bluetooth and other wireless communication terminals to avoid the cumbersome laying of wired communication lines. A complete system usually includes a water control management platform deployed on a local server in a school, water control equipment installed in water use areas, and a special application program on a user's mobile terminal.

[0003] The typical working process is as follows: the user registers an account and logs in through the mobile application; each water control device has a unique number, and the user needs to manually input the device number to query the status and send valve control instructions; the water control platform deployed locally is responsible for checking the legality of the user's identity and forwarding control instructions to the corresponding device; the water control device measures the user's consumption time or water volume while executing control, and generates a consumption order after the consumption ends, which is returned to the platform through the water control device to complete payment, and the management platform is responsible for setting system parameters such as billing mode and unit price.

[0004] When dealing with device offline consumption scenarios, existing technologies mainly rely on pre-issuing a personnel whitelist to device terminals. Specifically, after the user's mobile application establishes a connection with the water control device through Bluetooth, device control can be achieved. After the consumption ends, the water control device locally generates a consumption order, which is then uploaded to the water control platform asynchronously through the mobile phone's 4G network, and finally the platform completes payment processing.

[0005] This existing technology has a significant defect: its overall operation process highly depends on the continuous availability of the water control platform service in the school. Once the local server fails or the network is interrupted, the entire water control system will be paralyzed, and the user will be unable to perform any consumption operation, seriously affecting the daily water experience. SUMMARY

[0006] In order to overcome the above-mentioned problems in the prior art, the present application provides a method and system, which adopts the following technical solution:

[0007] In a first aspect, the present application provides a double-offline transaction authentication method for a Bluetooth water control system, comprising:

[0008] detecting the communication state between the user terminal APP and the local server;

[0009] When the communication state is abnormal, the user terminal APP switches the communication connection with the cloud server and loads the water service interface;

[0010] The Bluetooth water control device receives the instructions of the water service interface and performs the corresponding valve opening or closing operation, and generates a consumption order based on the order number. When the communication between the Bluetooth water control device and the local server is restored, the consumption order is uploaded to the local server to complete the order processing.

[0011] Further, before the Bluetooth water control device receives the instructions of the water service interface and performs the corresponding valve opening operation, it includes:

[0012] Detecting whether the user terminal has opened Bluetooth. When Bluetooth is opened, the water service interface establishes Bluetooth connection with the Bluetooth water control device;

[0013] When Bluetooth is not opened, the user terminal is prompted to open Bluetooth, and the water service interface establishes Bluetooth connection with the Bluetooth water control device.

[0014] Further, after the water service interface establishes Bluetooth connection with the Bluetooth water control device, the water service interface assembles the valve opening and closing instructions and sends them to the Bluetooth water control device.

[0015] Further, the Bluetooth water control device receives the instructions of the water service interface and performs the corresponding valve opening operation, which includes:

[0017] Further, the Bluetooth water control device receives the instructions of the water service interface and performs the corresponding valve closing operation, which includes:

[0018] The water service interface sends the end water instruction to the Bluetooth water control device. The Bluetooth water control device receives the end water instruction and closes the valve. Based on the order number, a consumption order is generated and stored. When the communication between the Bluetooth water control device and the local server is restored, the consumption order is automatically uploaded to the local server to complete the order processing.

[0019] Further, after the order processing is completed, the local server's background management service processes the consumption order and returns the consumption result to the water service interface for user query.

[0025] a water service interface (5) deployed in the cloud server (2) for controlling the on-off valve and consumption operation of the Bluetooth water control device (3) when the Bluetooth water control system is in a double offline state.

[0026] Further, the implementation process of the system is as follows:

[0027] The user terminal APP (4) detects the communication state with the local server (1), and when the local server (1) is abnormal and cannot establish a communication connection, the user terminal APP (4) automatically switches to the cloud server (2) and loads the water service interface (5); the water service interface (5) establishes a connection with the Bluetooth water control device (3) through Bluetooth communication, and assembles the on-off valve instruction and sends it to the Bluetooth water control device (3);

[0029] The background management service of the local server (1) processes the consumption order, and returns the consumption result to the water service interface (5) for user query.

[0030] In a third aspect, the present application provides an electronic device, comprising:

[0031] one or more processors; a memory; and one or more computer programs, wherein the one or more computer programs are stored in the memory, and the one or more computer programs include instructions that, when executed by the device, cause the device to perform the method of the first aspect.

[0032] In a fourth aspect, the present application provides a computer readable storage medium, which stores a computer program, and when the computer program is run on a computer, the computer program causes the computer to perform the method of the first aspect.

[0033] In a fifth aspect, the present application provides a computer program for executing the method of the first aspect when the computer program is executed by a computer.

[0034] In a possible design, the program in the fifth aspect can be stored, in whole or in part, on a storage medium packaged with a processor, or stored, in part or in whole, on a storage medium not packaged with the processor.

The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are they necessarily mutually exclusive of one another. It is expressly understood that the embodiments described herein are merely possible embodiments of the present application. It is expressly understood that the embodiments described herein are merely possible embodiments of the present application.

[0042] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0043] This application, when both the Bluetooth water control device and the backend management service are offline, employs a dual-application architecture deployed on a local server and a cloud server to automatically switch to the mobile water consumption application deployed on the cloud platform when the local service becomes unavailable. This application effectively solves the problem of users being unable to consume water normally due to the offline status of the water control device or the local server, ensuring the continuity and reliability of water services.

[0044] Example 1:

[0045] Please refer to Figure 1 The following is a method for dual offline transaction authentication in a Bluetooth water control system provided in this application embodiment, and the specific implementation process is as follows:

[0046] Step S1: Detect the communication status between the user-side APP and the local server.

[0047] In this embodiment of the application, the user-side APP is the host of the water service interface, used to communicate with the local server and the cloud server.

[0048] In this embodiment, the local server is used to deploy the mobile application, management system, and database of the water control system.

[0049] Step S2: When the communication status is abnormal, the user-end APP switches the communication connection with the cloud server and loads the water service interface.

[0050] In this embodiment of the application, the cloud server is used to deploy the water service interface, which is a water service H5.

[0051] It should be noted that the water service interface is deployed on a cloud server and is used to control the opening and closing valves and consumption operations of the Bluetooth water control device when the Bluetooth water control system is in a dual offline state, and to establish communication between the Bluetooth water control device and the cloud server.

[0052] Step S3: The Bluetooth water control device receives instructions from the water service interface and performs the corresponding valve opening or closing operation. It also generates a consumption order based on the order number. Once communication between the Bluetooth water control device and the local server is restored, the consumption order is uploaded to the local server to complete the order processing.

[0053] In this embodiment of the application, the Bluetooth water control device (3) is used to complete the authentication of the user's identity in an offline scenario and to generate a water control consumption order.

[0054] In this embodiment of the application, before the Bluetooth water control device receives the instruction from the water service interface and executes the corresponding valve opening operation, it includes:

[0055] Detect whether Bluetooth is turned on on the user terminal. If Bluetooth is turned on, establish a Bluetooth connection between the water service interface and the Bluetooth water control device.

[0056] If Bluetooth is not enabled, the user will be prompted to enable Bluetooth and establish a Bluetooth connection between the water service interface and the Bluetooth water control device.

[0057] In this embodiment, after the water service interface establishes a Bluetooth connection with the Bluetooth water control device, the water service interface assembles and sends the valve switching command to the Bluetooth water control device.

[0058] In this embodiment of the application, the Bluetooth water control device receives instructions from the water service interface and executes the corresponding valve opening operation, including: the water service interface sends the water code to the Bluetooth water control device, the Bluetooth water control device verifies the water code and risk control parameters, and when the verification is successful, the Bluetooth water control device generates an order number and executes the valve opening operation.

[0059] It should be noted that the risk control parameters include: single-purchase limit, single-purchase time limit, daily purchase limit, offline purchase amount, and number of offline purchases. The single-purchase limit, single-purchase time limit, and daily purchase limit are used to restrict the maximum purchase amount of a user in a single transaction or in a single day, mainly to prevent users from forgetting to turn off the valve and causing losses. The transaction will automatically end after the parameter limit is reached. The offline purchase amount and number of offline purchases mainly limit the maximum amount and number of purchases made by a single device in a dual offline scenario, to avoid too many unuploaded records.

[0060] It should be noted that the risk control parameters are set by the management backend, and the Bluetooth water control device will automatically download and update the risk control parameters when it is online.

[0061] In this embodiment of the application, the Bluetooth water control device receives instructions from the water service interface and executes the corresponding valve closing operation, including: the water service interface sends an end-of-water-use instruction to the Bluetooth water control device; the Bluetooth water control device receives the end-of-water-use instruction and closes the valve; a consumption order is generated based on the order number and stored; when communication between the Bluetooth water control device and the local server is restored, the consumption order is automatically uploaded to the local server to complete the order processing.

[0062] In this embodiment of the application, after the order processing is completed, the background management service of the local server processes the consumption order and returns the consumption result to the water service interface for the user to query.

[0063] Please refer to Figure 2 The following is a timing diagram of a dual offline transaction authentication method for a Bluetooth water control system provided in an embodiment of this application. The specific implementation process is as follows:

[0064] S1. When the user launches the mobile APP and enters the water control application, the user's APP first determines whether the local water control service is normal. If the service is abnormal, it will automatically redirect to the cloud server and open the water service H5 page.

[0065] S2. After entering the water service H5 page, the user should turn on the mobile phone Bluetooth according to the page prompts and establish a Bluetooth connection with the Bluetooth water control device.

[0066] S3. The user enters their personal water code on the water service H5 page, and the water service H5 sends the water code and valve opening command to the Bluetooth water control device.

[0067] S4. The Bluetooth water control device receives the valve opening command, verifies the user's identity and relevant risk parameters, generates an order number and executes the valve opening operation after successful verification.

[0068] S5. After the user finishes using water, click the "End Use" button on the Water Service H5 page, and the Water Service H5 will send a valve-closing command to the Bluetooth water control device.

[0069] S6. After receiving the valve closing command, the Bluetooth water control device closes the valve, generates a consumption record and stores it; after the Bluetooth water control device resumes communication with the local server, it automatically uploads the consumption order to the local server and completes the order processing.

[0077] The Bluetooth water control system in this application includes a Bluetooth water control device and a local server.

[0078] The specific operation process of a dual offline transaction authentication system for a Bluetooth water control system is as follows:

[0079] The user terminal APP (4) detects the communication status with the local server (1). When the local server (1) is abnormal and cannot establish a communication connection, the user terminal APP (4) automatically switches to the cloud server (2) and loads the water service interface (5).
