[0006] The data acquisition module is used to collect data from sensors and perform preliminary processing. The data acquisition module is a data acquisition matrix that adopts a node cascade transmission architecture. In the data acquisition stage, the data acquisition matrix supports parallel operations in the horizontal dimension, which is used to simultaneously collect data, transmit data, and perform streaming operations from multiple sources. In the data processing stage, the data acquisition matrix supports distributed operations in the vertical dimension, which is used to perform data processing or distributed operations in parallel on several nodes.

[0014] The beneficial effects of this technical solution are:

[0015] 1. The present invention adopts a data acquisition matrix to construct a data acquisition module, and supports horizontal parallel operation and vertical distributed operation. Parallel operation accelerates the data acquisition and transmission process and reduces the overall processing time.

[0016] 2. The present invention adopts a node cascade transmission architecture, which achieves efficient scalability and cost-effectiveness by simplifying the network topology and reducing the complexity of wiring. At the same time, the cascade configuration is intuitive. When a fault occurs, it is easier to find the source of the fault and handle it, which makes it convenient for students to understand the transmission process of the Internet of Things and troubleshooting.

[0019] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments:

[0020] Example 1

[0021] The present invention provides an Internet of Things sensor node cascade data transmission system, comprising a data acquisition module, a data transmission module and a data application module;

[0022] The data acquisition module is used to collect data from sensors and perform preliminary processing. The data acquisition module is a 4*4 data acquisition matrix and adopts a cascade transmission architecture. In the data acquisition stage, the data acquisition matrix supports parallel operations in the horizontal dimension and is used to simultaneously collect data, transmit data and stream operations from multiple sources. The horizontal dimension of the data acquisition matrix is ​​composed of an acquisition node and several transmission nodes. Node cascade transmission is adopted between acquisition nodes and transmission nodes, and between transmission nodes. In the data processing stage, the data acquisition matrix supports distributed operations in the vertical dimension and is used to perform data processing or distributed operations in parallel on several nodes. Among them, the sensors include temperature sensors, sound sensors, humidity sensors, vibration sensors, pressure sensors, speed sensors, pressure sensors or photoelectric sensors, etc.

[0023] The data transmission module integrates the network function, which is used to perform data transmission and data communication between the data acquisition module and the data application module. The network function uses crawler software technology, and also includes the Internet and ad hoc network;

[0024] The data application module supports data output, data application and data display, and is used for exporting data, applying data and visualizing data. It also has a data storage area for storing data; wherein, the visualization method of data display includes LED display, seven-segment digital display, indicator light display, table display or graphical display;

[0025] When in use, multiple sensor data in the data acquisition module are collected simultaneously. After the data is collected, transmitted and processed, the data is transmitted to the data application module through the data transmission module, and the data application module stores, applies, outputs or displays the data;

[0026] Example 1 Transmission process of sensor node cascade data

[0027] like Figure 1 As shown, the data transmission process is: D1 node → node → node → node S1

[0028] D2 node → node → node → node S2

[0029] D3 node → node → node → node S3

[0030] D4 node → node → node → node → node S4

[0031] When the system is running, the sensor collects data → D1 / D2 / D3 / D4 collection nodes → transmission nodes → transmission nodes → S1 transmission nodes / S2 transmission nodes / S3 transmission nodes / S4 transmission nodes; it can be seen that the sensors operate in parallel, multiple sensors can work at the same time, and the collection nodes and transmission nodes, and the transmission nodes and transmission nodes are all node cascades;

[0032] Embodiment 1 Hardware connection of sensor node cascade data transmission

[0033] like Figure 2 As shown, the data collected by the sensor → P0 port of MCU1 → P3 port of MCU1 → P0 port of MCU2 → P3 port of MCU2 → P0 port of MCU3 → → P3 port of MCU3 → next level;

[0034] When the system starts running, the data from the sensor goes through MCU1, MCU2, MCU3, and the next level. That is, the sampling node MCU1’s P0 is connected to the sensor, P3 is connected to MCU2’s P0, MCU2’s P3 is connected to MCU3’s P0, and MCU3’s P3 is connected to the next level, forming a complete cascade system.

[0035] The above is only an embodiment of the present invention, and the common knowledge such as the known specific technical solutions or characteristics in the solution is not described in detail here. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the technical solution of the present invention, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
