Description

Technical Field

[0001] This invention belongs to the field of teaching equipment technology, specifically relating to a portable IoT wireless I / O module interactive teaching platform. Background Technology

[0002] Currently, the widespread adoption of industrial internet platforms and smart factories is driving a new production model of "connectivity and real-time controllability for everything," placing higher demands on manufacturing sites for low-latency, high-reliability, and highly adaptable data acquisition and monitoring systems. For industrial applications involving edge intelligence, distributed decision-making, and predictive maintenance, data I / O systems with wireless communication capabilities have become indispensable underlying infrastructure in intelligent manufacturing systems. To meet the high demands of intelligent manufacturing system teaching for systematicity, interactivity, and engineering practice capabilities, there is an urgent need to construct a concrete, immersive, interactive teaching device that combines wireless data acquisition, remote acquisition and control, and visual monitoring functions to assist theoretical teaching in comprehensively understanding the structure and logic of data acquisition and production monitoring, and to cultivate students' problem-solving thinking and system integration abilities. Existing teaching aids suffer from problems such as limited functionality, poor interactivity, and detachment from industrial realities, and can no longer meet the needs of new engineering education.

[0003] To address the shortcomings of existing technologies, people have conducted long-term explorations and proposed various solutions. For example, Chinese patent literature discloses an industrial Internet of Things (IoT) teaching and training platform [202411420191.7], which includes an application layer and an industrial controller. The industrial controller is connected to an industrial monitoring screen, a ZIGBEE module, a multi-channel IO expander, and an NB-IoT module. The ZIGBEE module is connected to the multi-channel IO expander and is also connected to an actuator group and a sensor group.

[0004] The above solution addresses the problems of IoT teaching to some extent, but it still has many shortcomings, such as limited functionality and poor interactivity. Summary of the Invention

[0005] The purpose of this invention is to address the above-mentioned problems by providing a reasonably designed and highly interactive portable IoT wireless I / O module interactive teaching platform.

[0006] Another objective of this invention is to address the aforementioned problems by providing a control method for a feature-rich portable IoT wireless I / O module interactive teaching platform.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a portable IoT wireless I / O module interactive teaching platform, comprising a platform body, on which IoT wireless I / O modules and experimental modules are installed using a plug-and-play configuration. The platform body is equipped with a visual teaching component controlled by the IoT wireless I / O modules and experimental modules. The IoT wireless I / O modules serve as the central hub for data acquisition, logic processing, and communication, while the various experimental modules act as standard sensing and execution units, connected to the central hub via plug-and-play interfaces, thus enabling system reconfiguration. The visual teaching component transforms abstract data and control logic into a carrier of intuitive physical motion, forming a complete closed-loop teaching system encompassing signal perception, intelligent decision-making, physical execution, and effect observation.

[0008] In the aforementioned portable IoT wireless I / O module interactive teaching platform, the IoT wireless I / O modules used are from the WISE series. Experimental modules include, but are not limited to, commonly used typical I / O application objects such as RGB light modules, button modules, joystick modules, photosensitive modules, temperature and humidity modules, and ultrasonic modules. The WISE series IoT wireless I / O modules integrate multiple digital input / output (DI / DO) and analog input (AI) interfaces, and have built-in high-performance processors and communication units such as Wi-Fi / Ethernet. It can simultaneously process button switching signals, analog signals such as joystick voltage, photoresistor values, and temperature and humidity analog signals, as well as digital signals such as ultrasonic ranging values ​​communicated through specific protocols. The RGB light module is used to demonstrate pulse width modulation (PWM) color control. These modules collectively cover common sensor and actuator types in the IoT, and the experimental modules can be further expanded according to actual needs.

[0009] In the aforementioned portable IoT wireless I / O module interactive teaching platform, the IoT wireless I / O module and experimental module are connected to a power supply circuit. The platform body houses a motor and indicator lights connected to the power supply circuit. The power supply circuit provides a stable and isolated power source for the entire system. A geared motor is used as the core actuator; its start / stop, speed, and direction are typically controlled by the IoT module's digital output port via an intermediate relay or motor driver. The indicator lights are directly driven by the module's digital output port, used to visually display system status or logical output results.

[0010] In the aforementioned portable IoT wireless I / O module interactive teaching platform, the visual teaching component includes a slide assembly installed within the platform body, which is equipped with a ball lifting assembly. The balls represent data packets or controlled objects, and their movement paths are determined by multiple controlled mechanical parts, thereby transforming intangible program logic into tangible, engaging, and continuous motion trajectories, enhancing the immersion and comprehension of the teaching process.

[0011] In the aforementioned portable IoT wireless I / O module interactive teaching platform, the slide assembly includes a rotating base rotatably mounted within the platform body and driven to rotate by a motor. A vertically arranged support frame is mounted on the rotating base, and a first slide rail and a second slide rail are fixed on the support frame. A guide platform is provided at the top of the support frame to guide the ball bearings into the first and second slide rails. A stop post is provided on the guide platform opposite to the first slide rail. The first slide rail has a first track arranged at an incline and coiled position, and a second track is connected at the lower end of the first track to guide the ball bearings to fall vertically onto the rotating base. The second slide rail includes a third track arranged in a coiled manner on the guide platform. A guide opening is opened at the lower end of the guide platform opposite to the third track for the ball bearings to fall. A fourth track arranged in a spiral coiled manner is mounted on the support frame.

[0012] This slide assembly is a multi-path, multi-state mechanical decision-making and execution system. Stoppers on the guide platform obstruct the balls, limiting their descent speed. The spiral track of the first slide rail simulates a processing step or delay; the helical track of the second slide rail simulates another processing flow. The balls eventually fall back to the rotating base, forming a loop that can be re-lifted, symbolizing the continuous operation of industrial production or data processing. The rotating base can be controlled by a stepper motor to achieve precise angular positioning to coordinate with the lifting assembly.

[0013] In the aforementioned portable IoT wireless I / O module interactive teaching platform, the ball lifting assembly includes a spiral lifting rod rotatably mounted within the platform body. Driven by a motor, the spiral lifting rod propels the balls upwards along a spiral path to the guide platform. The ball lifting assembly simulates a material transfer or data loading process. Driven by the motor, it rotates and uses friction to steadily lift the balls at the bottom along a spiral path to the top guide platform. Controlling this motor is a key output task of the IoT module, demonstrating how control commands are translated into continuous physical actions.

[0014] In the aforementioned portable IoT wireless I / O module interactive teaching platform, a transparent cover is installed on the main body of the platform to enclose the slide assembly for safety protection, preventing accidental contact with high-speed moving parts, while ensuring an unobstructed field of view, meeting the dual standards of safety and visibility for teaching equipment.

[0015] In the aforementioned portable IoT wireless I / O module interactive teaching platform, the main body of the platform includes a base, a support tube installed on the upper end of the base, and a top cover installed on the upper end of the support tube; the IoT wireless I / O module and the experimental module are plugged and unplugged onto the support tube via a module adapter.

[0016] A control method for a portable IoT wireless I / O module interactive teaching platform includes the following steps: S1: Module initialization. The IoT wireless I / O module starts and completes initialization, which includes hardware self-test, loading firmware, reading stored configuration files such as network parameters, I / O configuration, control logic, etc., to establish a software environment for normal operation. S2: Network interaction. The IoT wireless I / O module establishes a communication connection with the external network, supporting access to local configuration terminals or cloud platforms. Its core is the establishment of the TCP / IP protocol stack and upper-layer application protocols such as MQTT and HTTP. As a client, the IoT wireless I / O module actively connects to the router or cloud server to realize the device to the cloud, laying the channel foundation for remote interaction. S3: Data processing and decision-making. The IoT wireless I / O module collects, parses, and performs logical judgments on input field signals or commands to generate processing results or control commands. The IoT wireless I / O module collects data from each interface in real time, performs filtering, calibration, and dimension conversion, and performs decision-making calculations based on preset logic or real-time commands issued from the cloud, thereby reducing dependence on the cloud and improving response speed and reliability. S4: Execution and Collaboration. The IoT wireless I / O module drives the execution output interface to trigger the actions of field actuators and supports dual-mode operation of local autonomy and cloud collaboration. During the execution phase, the module outputs digital / analog control signals to the actuator. Dual-mode operation is crucial when the network is normal; execution instructions can come from the cloud. When the network is interrupted, the module relies entirely on the local logic processing results for control, ensuring the system's basic operational capability under abnormal conditions.

[0017] In the control method of the aforementioned portable IoT wireless I / O module interactive teaching platform, at least one of the following operating modes is adopted: Local Configuration Mode: The IoT wireless I / O module enters a configurable state, receives network parameters from an external configuration terminal, writes them to storage, switches to working mode, and restarts. Based on the configuration parameters, it accesses the target network to verify network access and data acquisition communication functions. This mode is typically implemented based on an access point (AP) or SoftAP mode. The module temporarily becomes a Wi-Fi hotspot. After configuring mobile phones and other terminals to connect, the module writes parameters such as the target Wi-Fi's SSID, password, and cloud platform address to its non-volatile memory via a built-in web server or a dedicated configuration protocol. After restarting, the module uses the new parameters to connect to the network. Remote control mode: After the field actuator connects to the IoT wireless I / O module, the IoT wireless I / O module connects to the IoT communication network and establishes a connection with the cloud control platform. The remote client generates and sends control commands through the cloud platform. The IoT wireless I / O module parses the commands and drives the execution output interface. This mode is a typical client-server-device (C / S / B) IoT application mode. The cloud control platform acts as a message relay and logic hub. Commands from the remote client are sent to IoT wireless I / O modules that have subscribed to the topic through the platform using secure protocols such as MQTT. The IoT wireless I / O module parses commands in formats such as JSON and executes the corresponding I / O operations. Remote acquisition mode: After the field sensor signal access module is activated, the IoT wireless I / O module acquires the signal and completes the digitization / engineering quantity conversion. The signal is then uploaded to the cloud platform for storage via wireless communication. Remote clients retrieve the data from the cloud and perform visualization and analysis. This mode focuses on data uploading to the cloud. The IoT wireless I / O module acquires sensor data periodically or triggered by a specific time, encapsulates it into data packets, and sends them to the cloud platform's time-series database or message queue via a wireless network. Remote clients such as web dashboards and mobile apps retrieve the data by calling the cloud platform's API for visualization or big data analysis. Local Control Mode: The IoT wireless I / O module performs edge acquisition processing on the input field sensor signals, determines whether preset control conditions are met, and if so, generates local control commands and drives their execution. Simultaneously, it monitors network status; in case of anomalies, it enters an offline autonomous control mode, and in case of normal operation, it enters a cloud-based collaborative operation mode. Internally, the IoT wireless I / O module runs a local control logic program, independently of the cloud for judgment and execution. It continuously performs network heartbeat checks; if a connection timeout with the cloud is detected, it automatically switches to an offline autonomous state fully dependent on local logic. After network recovery, it automatically switches back to a cloud-based collaborative state, enabling seamless recovery and degradation.

[0018] Compared with existing technologies, the advantages of this invention are as follows: The IoT module and various sensors / actuators are pluggable, improving the flexibility and scalability of experiments. Different input / output modules can be freely combined to quickly build various application scenarios, facilitating inquiry-based and project-based teaching. The ball bearing slide and lifting assembly transform abstract digital signals and logic control results into continuous and intuitive physical movements such as ball conveying, lifting, sorting, and falling. Visualization lowers the barrier to understanding IoT control logic and intuitively demonstrates the execution effect of remote commands and system status. It supports signal acquisition and execution at the device end, enabling communication and remote acquisition and control with the cloud platform. This allows students to fully practice the entire IoT process from the perception layer, network layer to the platform layer and application layer, and understand the typical architecture of modern industrial IoT systems.

Detailed Implementation

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0021] like Figure 1-13As shown, a portable IoT wireless I / O module interactive teaching platform is presented. The platform body 1 serves as the physical carrier of the system and adopts an open architecture design. Its core control unit is the IoT wireless I / O module 2. This solution uses the WISE-4012 model as an example, which is essentially an industrial-grade IoT gateway with data acquisition, logic processing, wireless communication, and edge computing capabilities. Around this core, the platform flexibly connects various experimental modules 3 through standardized plug-in interfaces, such as RGB light modules, button modules, joystick modules, photosensitive modules, temperature and humidity modules, and ultrasonic modules, forming a reconfigurable sensing and execution layer.

[0022] Specifically, to transform abstract control logic and data flow into intuitive physical phenomena, a set of visual teaching components 4 is integrated into the main platform 1. In this basic scheme, this component is specifically manifested as a precision mechanical demonstration system consisting of a slide rail component 5 and a ball lifting component 6. The slide rail component 5 includes a rotating base 51 driven by a motor, on which a support frame 52 is erected, and it has a first slide rail and a second slide rail with two different paths. The ball lifting component 6 uses a spiral lifting rod 61, driven by a motor, to transport the balls from the bottom to the top guide platform 53. The guide platform 53 has a stop post 54 to limit the falling speed of the balls. The first slide rail includes a coiled first track 55 and a second track 56 leading to the rotating base 51; the second slide rail includes a coiled third track 57 and a spirally coiled fourth track 59, through which the balls can fall into the fourth track 59 via a guide opening 58 at the lower end of the guide platform 53.

[0023] The entire slide assembly 5 is enclosed within a transparent cover 11, ensuring both safety and ease of observation. The platform body 1 typically consists of a base 12, a support cylinder 13, and a top cover 14. All IoT wireless I / O modules 2 and experimental modules 3 are integrated onto the support cylinder 13 via module adapters 15 and are powered by a unified power supply circuit 31, driving internal motors, indicator lights, and other actuators. The control method is as follows: S1: Module initialization, IoT wireless I / O module 2 starts and completes initialization; S2: Network interaction, IoT wireless I / O module 2 establishes a communication connection with the external network, supporting access to local configuration terminals or cloud platforms; S3: Data processing and decision-making. The IoT wireless I / O module 2 collects, parses, and performs logical judgments on the input field signals or commands to generate processing results or control commands. S4: Execution and Collaboration. The IoT wireless I / O module 2 drives the execution output interface to trigger the action of the field actuator and supports dual-mode operation of local autonomy and cloud collaboration.

[0024] Furthermore, this control method is specifically manifested in a variety of selectable operating modes: Local configuration mode: The IoT wireless I / O module 2 enters the configurable state, receives network parameters sent by the external configuration terminal, writes them to storage, switches to the working mode and restarts, and accesses the target network based on the configuration parameters.

[0025] Remote control mode: The IoT wireless I / O module 2 connects to the IoT communication network and establishes a connection with the cloud control platform. The remote client generates and sends control commands through the cloud platform. After parsing the commands, the IoT wireless I / O module 2 drives the execution output interface.

[0026] Remote acquisition mode: The IoT wireless I / O module 2 acquires the signals from the connected field sensors and completes the digitization / engineering quantity conversion. The signals are then uploaded to the cloud platform for storage via wireless communication, allowing remote clients to access and analyze them.

[0027] Local control mode: The IoT wireless I / O module 2 performs edge acquisition processing on the input field sensor signals, determines whether the preset control conditions are met, and generates local control commands and drives their execution if they are met. At the same time, it monitors the network status. If there is an abnormality, it enters the offline autonomous control mode, and if there is a normal status, it enters the cloud collaborative operation mode. Example 1

[0028] This embodiment is a teaching system for automated sorting and status indication based on environmental perception. The purpose of this system is to help trainees understand the integrated application of sensor data acquisition, local logic control, remote status monitoring, and manual intervention. Specifically, the photosensitive module and button module are used as inputs and connected to the WISE-4012 IoT wireless I / O module 2; the stop column 54 can be equipped with an electromagnet to drive lifting, and works with an RGB light module as output.

[0029] In local control mode, the IoT wireless I / O module 2 continuously collects the illuminance value of the photosensitive module. When the illuminance is lower than the set threshold, the module automatically executes local logic and generates two outputs: first, it controls the baffle 54 to rise, allowing the ball bearing to enter the first slide rail; second, it adjusts the RGB light to a warm yellow low-brightness mode as an ambient lighting indicator.

[0030] During remote monitoring and intervention, the IoT wireless I / O module 2 uploads real-time illuminance values ​​and the current status of the 54-liter baffle to the cloud platform via remote acquisition mode for remote client viewing. Trainees can manually click the "Force Sorting Path" button on the cloud interface via remote control mode to issue a command to lower the baffle, ensuring the ball bearing enters the first slide rail without obstruction, demonstrating the logic of remote intervention taking precedence over local automatic operation. The ball bearing selects different slide paths based on light intensity or remote commands, and the RGB light color and brightness change accordingly, intuitively presenting the entire process of sensing-decision-execution. Example 2

[0031] This embodiment is used for material recycling production line simulation and cloud-edge collaborative experiment. It uses the rocker module and ultrasonic module as inputs and the motor controlling the spiral lifting rod 61, the motor controlling the rotating base 51, and the indicator light as outputs.

[0032] The local system sends a start signal via a joystick module, and the IoT wireless I / O module 2 activates the motor of the ball lifting assembly 6, lifting the ball to the guide platform 53. The platform is designed with two operating logics. By default, it operates in local control mode: according to a preset program, it automatically controls the rotating base 51 to deliver the ball to a predetermined angle and complete one sorting slide. The status data of the entire process is uploaded to the cloud. The teacher sends a new material handling process instruction package in remote control mode through the cloud platform. After receiving the instruction, the IoT wireless I / O module 2 switches to cloud collaborative operation mode, parses and executes the complex process. If the network is intentionally interrupted, the module immediately detects the anomaly and seamlessly switches to offline autonomous control mode, executing the most basic safeguard loop process to demonstrate the resilience of the industrial system in the event of a network outage. Students can clearly observe the complete automated process of ball lifting, transfer, and sorting, and can intuitively judge the current operating mode of the system through the indicator light colors. Example 3

[0033] This embodiment is used for an experiment on an intelligent warehouse environment monitoring and adaptive adjustment system, in which the temperature and humidity module is used as the core environmental perception input; and the indicator lights, RGB light module and slide rail assembly 5 are used as outputs.

[0034] The IoT wireless I / O module 2 collects temperature and humidity data at high frequency in a remote acquisition mode and uploads it to the cloud. Students can observe real-time data curves and historical reports on a remote client and perform preliminary data analysis. Complex local control logic is set within the IoT wireless I / O module 2. For example, if the temperature exceeds threshold A, a red alarm indicator light is illuminated, and the RGB lights are adjusted to a cool color; if the humidity exceeds threshold B, the slide assembly 5 and the ball lifting assembly 6 are controlled to select a longer slide rail, simulating an increase in the material drying process time. If both temperature and humidity are normal, the green light remains on, the ball follows the shortest path, and the simulated process is smooth.

[0035] Teachers can discover new threshold patterns based on cloud-based data analysis results and remotely update the control logic parameters within the IoT wireless I / O module 2 via local configuration or cloud commands to optimize and iterate control strategies. Changes in environmental parameters directly trigger a chain reaction of changes in indicator lights, light colors, and ball bearing movement paths. This presents invisible environmental data and its processing strategies comprehensively through multi-dimensional visual elements, profoundly illustrating the closed-loop essence of IoT perception-analysis-execution.

Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
