การพัฒนาแอปพลิเคชันบนระบบปฏิบัติการแอนดรอยค์ สำหรับควบคุมรถสำรวจพื้นที่เสี่ยงภัยผ่านเครือข่ายไร้สาย

Abstract

This project is the development of applications on Android operating system for controlling the surveying car in risky area through a wireless network. The main objective is to design and build an application that can control the surveying car to explore in any area through a wireless network(Wi-Fi). In terms of the surveying car. It is designed to move in the horizontal direction. It have a sensor that can detect flammable gas and it have IP camera for sending the picture signal from the surveying car to the screen on the tablet by controlling through on Android tablet operating system. In the experiment of application can connect with the surveying car and control the movement of the surveying car perfectly. The results of experiment show that the lime for the movement of the surveying car in the model map compare with the real-time calculated (hat the percentage of error is 14.20%. The experiment of trial distance for contrllong the surveying car show that the longest distrancc is 50 meters in the open space and 20 meters in the building. In the experiment of IP camera show that it can be displayed and controlled the direction ol rotation completely in every position degrees. In the experiment of detecting flammable gas show that the system can operate efficiently. It can capture flammable gas accurately such as Alcohol lighter. Mosquito spray.
