| In this paper,a kind of demonstrator which is based on Android operating system and Wi Fi technology is designed by studying the current research of welding robot teaching function and comparing with Android,Windows two mobile operating system.Meanwhile,this paper has referred to different brand of industrial robot teaching system design and layout experience.The main contents of this paper are divided into the following aspects:This paper builds an information instruction transmission system based on Wi Fi technology.In this paper,the ESP8266 Wi Fi module is used as the server side,the teaching device is used as the client,the Wi Fi network environment is set up to realize the face that the demonstrator can transmit data with the welding robot.The core of the processing is STM32F103ZET6 processor,which is responsible for the classification of transmission instructions,and motor movement is ultimately controlled by motor driver.AT command is used to design and develop the driver of Wi Fi module and realize data transmission between demonstrator and welding platform.In this paper,a series of communication protocols are established based on different welding tasks.By summarizing different welding paths and different welding modes,a communication protocol is established to ensure the reliability of instruction transmission,including start bit,mode bit,data bits and end bit,which is responsible for data transmission betweenThe working mechanism of Android operating system is studied.Through reading related technical documents,we can understand the message transmission mechanism and the background operation mechanism of Android system,and install the teaching software in the target device.Finally,we repeatedly test the stability and compatibility of the teaching software on the target device.Use the Eclipse software tool to develop the Android application,which is mainly the human-computer interaction interface of the teaching system.The teaching system includes the welding program file management system,the teaching controlsystem,the trajectory simulation system and the program execution system.The program text translator is designed and implemented,and the program instruction is translated into the identifiable instruction format of the welding robot.At the same time,the data exchange between the teaching device and the welding robot is used to monitor the network connection state in real time.The existing welding simulation hardware platform is used to test the teaching operation to verify the accuracy of the teaching device.In this paper,we firstly use platform to do teaching reappearance test and welding trajectory simulation test.Finally,we have programmed text transmission test to test the file transmission ability of the teaching device.In this paper,the welding simulation platform is used to teach a curve,and the simulation is realized through the simulation function of the welding track of the instructing device.The correct welding procedure is transferred to the welding simulation platform for teaching and reproduction.Through the teaching and reproduction of the real workpiece,we can check the use of the display device in the production process.The analysis and test of the teaching system show that the teaching device can complete the planning and reproduction of complex path,and realize the transmission of program text,and at the same time,reduce the cost of learning and using. |
