Design and Implementation of Wireless Environment Monitoring System Based on STM32

This paper first designed the overall scheme of a wireless-based intelligent environment monitoring system; this system is comprised of the following four parts: server part, client part, slave computer part, and master computer part. The master computer is equipped with a wireless transmission module and an LCD module. Slave computers are equipped with temperature-humidity sensing modules and wireless transmission modules. The server side has two major interfaces: data display and server establishment. An Android phone as the client can realize the communication between the mobile APP and server through network communication to obtain environmental data in real time. The hardware part of the system consists of wireless transmission module, temperature and humidity module, smoke module, lighting module, flame module, and LCD module. The software implementation part mainly includes the design and implementation of serial communication, the design and implementation of wireless communication, the design and implementation of collection of data acquisition in each sensor module, and the design and implementation of network communication as well as the design and implementation of display unit. With the cooperation of these four parts, we can automatically sense and control the state of the environment to realize human-computer interaction.

Design and Implementation of Serial Communication for Automatic Titanium Alloy Sorting System

The heat generated during Titanium alloy cutting can cause bad products, which must be eliminated by Sorting System. This paper describes the design and implementation of serial communication between the automatic sorting machine and the host computer, introduces the system framework and the software flow, and gives a detailed introduction to the communication process, parameters setting and also gives part of the MFC dialog-based serial communication program. It shows that the design and implementation completely meets the requirements of systems performance and function.

Study of Serial-Communication in Home Environment Control System

This paper describes the implementation of serial communication between the PLC and the host-computer in the control system of home environment, gives a detailed introduction to the communication protocols, parameters setting and also gives part of the serial-communication program based on visual basic 6.0. It shows that this control system meets the requirements as expected.

Implementation of Serial Communication between Host Computer and PLC based on Host Link Protocol

The host link communication protocol between host computer and PLC (Programmable Logic Controller) is introduced in this paper, and a method of using API (windows application program interface) to realize serial communication between host computer and PLC is proposed, the software design process and the corresponding procedures of serial communication between host computer and PLC are given. Through reading or writing operations, data exchange between host computer and PLC are realized, which can effectively carry out the industrial field device monitoring and management. Taking OMRON CJ1H Series PLC as the testing object, testing software is written for verifying the function of the system. When the communication between host computer and PLC start, there are the reading delay and the writing delay which may seriously affect communication rate. By testing, the important data about delay time are obtained. It also shows the relationship between communication delay and byte length. According to obtained data, methods of improving the communication delay are given. The testing results show that the method is effective and real time in communication, and has the engineering application value.
