Based on the detected vibration signal, a measurement system was designed to solve current problem of closed centrifuge speed measurement. The collected and adjusted signal by sensor, then send it control unit STM32 for spectrum analysis get frequency. sampling data analysed processed in PC through serial communication. Programs were written achieve sampling, filtering storage, important parame...

People who like to care for plants need take of in addition the work pressure, which consumes people's time and energy. To solve this problem, an intelligent pouring system based on STM32 WiFi module ESP8266 was designed. The took STM32F103 development board as main control core, combined with ESP8266, soil moisture sensor, temperature humidity sensor DHT11, photosensitive resistance other sens...

By introducing a sinusoidal function into three-dimensional map, hyperchaotic map with three positive Lyapunov exponents is derived. The has two amplitude controllers, total controller, and partial controller. shares unique structure of two-leaf three-leaf attractors under united exponents. Furthermore, homogenous multistability found in the 3-D where initial data determine attractor combined d...

In view of the problems existing in traditional irrigation, such as high time cost, poor reliability, waste water resources. The intelligent irrigation system based on STM32 and BC95 is designed implemented. soil information received through temperature sensor humidity sensor, which sent from sampling node to remote terminal serial port. controller sends signal output end for irrigation. practi...

In this paper, a new technique to monitor and control bidirectional DC-DC converter was designed implemented precisely. A prototype of complete system is verified with efficient communication capabilities. This realized by integrating the internet things (IoT) operating converter. The IoT facilities further develop extend platform for system. soft switching will then convert battery voltage hig...

Abstract In Fretting is an important research direction in the detection of urban underground space structure. Traditional geophones have three issues with achieving fretting field, high cost, large size and low accuracy. A signal acquisition system based on AD7177 proposed to solve above problems, which takes STM32 as design core. decision-making scheme that combines vibration sensor introduce...

Intelligent scenic planning and management attempt to take advantage of the discipline in field artificial intelligence, explore new roles models for decision making with help machine learning academic research build a complete intelligent system. Labour costs energy account large share operating B&Bs. In order increase revenue while reducing losses, this paper designs an unattended system ...

The primary function of a distributed bus is to connect sensors, actuators, and control units that are used for an acquisition process. Application domains, such as industrial monitoring systems, manufacturing processes, or building automation, present different requirements not exactly invariable coherent. Updating data from Modbus-type devices involves updating through technique called pollin...
