Design And Implementation Of Distributed Ordering System Based On Embedded

In order to meet the consumers growing requirements about dishes taste, service quality, and environment, at the same time, for surviving in the environment of the fierce competition, businessmen think many methods, they need to meet the requirements and to reduce the cost. This graduation project designs the embedded ordering system which has small volume and powerful functions.The curriculum design needs the embedded system hardware platform and software to set up. to modify U-Boot installing files'Makefile file's code, that will be able to better guide Real-ARM2410 development board's the operating system, and that will be able to make the operating system nomally run. At the same time, it needs to cut the Linux kernel, to make the kernel meet the basic operation, and make the kernel remove the unuseful code. Finally, transplanting the modified U-Boot and the cutted Linux kernel can realize embedded system.It needs to realize data input through touch-screen. The subject adaptes a mouse interface Linuxtp which is proviced by Qt/Embedded, pressing the touch screen simulates the mouse action. In the code, set a monitor handle for the touch-screen, once the listener find the touch-screen generates some event, the program will read and process the relevant contact information in order to implement a touch screen click task. While touching the screen, it realize the the data input. It can realize the data input through adapting interface. The system needs to realize the sound function. Using QSound class can make sound play and pause. In the result, while the users click the food information, the system shows food picture, plays the sound of the food information. In conclusion, the system which transplants linux kernel can play the sound of the food information.Electronic system realizes distributed ordering system to wireless communication. It needs to weld GPRS module into the Real–APM2410, every cook takes charge different dish, after users order dish, the information need to be transmitted to different cook to realize distributed ordering system, GPRS module can realize the wireless transmission. while the users click the button, it can transmit the informations to the different cook. In conclusion, it can realize distributed ordering system by the wireless transmission.This curriculum design needs the embedded system hardware platform and software to set up, it makes us programme on it. It adapts a mouse interface Linuxtp to realize data input through touch-screen. It can use QSound class to realize the sound function. GPRS module can realize the wireless transmission.
