"Intelligence" is a hot word in society at that time, which reflects people's high requirements for quality of life. Smart home that makes people comfortable, convenient, and satisfied has emerged. This research takes the cloud platform as the software platform and combines the infrared telemetry technology to design a smart home control system with STM32 as the primary system controller, ZigBee as the home intranet communication module and the sensors as the environmental data acquisition module. The communication quality of the home intranet and the data monitoring performance of the cloud platform were tested. The experimental results show that the communication quality of the system is good, and there is almost no error packet, which can meet the daily needs of users. Users can remotely monitor the home environment and control the home equipment actions on the cloud platform.
In view of the current problem that there are too many social vehicles, and the parking spaces can not meet the needs, an outdoor cycle three-dimensional intelligent parking lot was designed. The parking lot can double the number of parking spaces in the original land area and can provide more intelligent services than the ordinary parking lot. In addition, it can make parking and fetching more convenient for the owners. PLC control and Zigbee wireless communication is used to combine the rotating parking space with the three-dimensional garage, which supports smart card, two-dimensional code reservation, and other convenient services. This design can intelligently manage the vehicles and parking spaces in the entire parking lot.
With manpower sorting system in view of the traditional logistics delivery, shipping and modern logistics system of vehicle transport task allocation in unreasonable situation, this article has carried on the AGV control system based on PLC intelligent logistics research, USES the PLC controller as a smart car (Automated Guided Vehicles, AGV) control module of Siemens industrial control software STEP7 as a platform, for the research of the system hardware design and software design, for domestic logistics enterprises with comprehensive logistics warehouse, vehicle transportation path is more complicated, In this paper, a system optimization scheme based on Floyd shortest path algorithm is proposed. Experiments verify that managers can control vehicles in real-time and master the necessary information and position of vehicles. The application of the improved Floyd shortest path algorithm in this system improves the operational efficiency of AGV path planning and reduces the task time.
