The Design And Development Of A Multi Protocol Intelligent Control System For The Internet Of Things

Under the fast-moving tides of internet development,Internet of Things(IoT),as an immerging industrial model of the new era,has attracted great attention and investment.Yet,the necessity of introducing new development to the traditional hardware is unquestionable,as the traditional hardware cannot cope with the technical needs of IoT.With the support of wireless communication,full scale intelligentization is feasible via the combination of both soft-and hardware.In the context of the above social background,I put forward the discussion and research of a new scheme that takes WeChat public account as the control platform in the paper.On this basis,the design and development of intelligent control system of multi-protocol Internet of things are carried out,so as to achieve the goal of multi-brand and multi-type terminal equipment system control.The system consists of four parts:system control platform,Web application server,gateway master node and terminal control node.The system control platform is the human-computer interaction part of the system to let users realize the system information and control of the system.The Web server serves as the bridge between the control platform and the gateway master node to transfer information.The gateway master node mainly completes the gateway function,as the WebSocket client to complete the data transmission and forwarding with the external network,and to complete the information interaction with the terminal control node.The terminal control node,as a function realization node,can realize temperature and humidity monitoring,air conditioning control,infrared text transmission,bluetooth communication and pin level control.The research mainly aims at the design and construction of soft and hardware for the above four parts and the five functions that are finally realized,and the function is realized;Variable judgment mechanism is added to realize automatic and intelligent control of air conditioning based on temperature and humidity data.After the system is designed and constructed,the system performs the function test and performance test on the system in the laboratory environment,and applies the random culling of deviation data method to the test data.Function test is mainly to check whether the correct response is made after sending the instruction and whether the corresponding function is started by the sensor control module.Performance test is mainly aimed at the communication quality of WiFi,ZigBee,bluetooth and infrared communication modes.The communication distance and the number of obstacle layers in the path are taken as variables for testing,and the test results are compared and analyzed.The test results show that ZigBee has more advantages than WiFi in the experimental environment at the communication level of master node and sub-node.Each sensor module works normally.The Internet of things multi-protocol intelligent control system designed and developed in this study has basically realized the expected functions and technical indicators.Due to the experimental conditions and personal technical depth,the system still needs to be improved.For example,the control platform can add multi-user login function and multi-user and multi-data analysis function to achieve more systematic and humanized control.At the same time,the system network scope and the number of controlled equipment can be expanded to establish a larger and more perfect system.
