Abstract

The invention provides a method for reloading and simulating various industrial Internet of Things sensor equipment. The method comprises a program control system, a simulation Internet of Things module, a real-time clock module, a communication module and a storage module, wherein the program control system is in communication with the simulation Internet of Things module through the communication module; the simulation Internet of Things module is connected to the storage module and the real-time clock module; the control method comprises the following steps of step 10, carrying out a heavyload stage, wherein the simulation Internet of Things module receives a reloading code sent by the program control system and reloads the equipment; step 20, carrying out a preset data sequence stage,wherein a preset data sequence is sent to the simulation Internet of Things module by the program control system and is stored in the storage module; and step 30, carrying out a simulation stage, wherein after the simulation Internet of Things module is successfully reloaded, a controller in the simulation Internet of Things module reads out the preset data sequence from the storage module, and outputs through a suitable communication mode according to the preset data sequence and a corresponding communication protocol.

Description

technical field [0001] The invention relates to the field of the Internet of Things, in particular to a method for overloading and simulating various industrial Internet of Things sensor devices for Internet of Things teaching or Internet of Things system design and debugging. Background technique [0002] In the industrial Internet of Things project, a large number of sensor devices are required. At present, most industrial IoT devices, such as temperature and humidity sensors, will convert the measured temperature and humidity data into digital signals, and use a certain communication protocol and a certain time interval, such as MODBUS, MQTT, etc., through RS232 or RS485 or WIFI communication method, send data. The IoT system needs to receive and analyze the data in the protocol, so as to obtain the real-time value of the sensor, and display, analyze, control and store it. [0003] In the design process of the IoT system, the IoT system obtains the actual sensor value b...

AI Technical Summary

Problems solved by technology

[0005] (1) For different IoT systems, different IoT sensors need to be purchased, and the cost is high

[0006] (2) Some IoT sensors cannot or are inconvenient to be debugged in the laboratory, such as wind speed sensors, carbon monoxide sensors, ultraviolet sensors, etc.

Taking the wind speed sensor as an example, during the test process, it is hoped that the wind speed from the minimum to the maximum can be tested, but it is difficult to achieve in the laboratory and the cost is high

For the carbon monoxide sensor, in order to test the measurement range of the carbon monoxide sensor, it is necessary to output different carbon monoxide concentrations in the laboratory, which is not safe and the cost is high

[0007] (3) Real IoT sensors are not easy to control their output, which is not conducive to debugging

For example, when it is necessary to test the temperature monitoring system of a swimming pool, the process of changing the temperature of the swimming pool is very slow, which is not conducive to the debugging of the IoT system

[0008] (4) Some real IoT sensors are expensive and difficult to maintain
