Arm embedded web server based on dac system
- 1. ARM EMBEDDED WEB SERVER BASED ON DAC SYSTEM Abstract: Data-Acquisition systems are in great demand in industry and consumer applications. In some applications, human beings have been replaced by unmanned devices that will acquire data and relay the data back to the base. There are data-acquisition and control devices that will be a substitute for a supervisor in a multisite job operation. A single person can monitor and even interact with the ongoing work from a single base station. Networked embedded systems have become quite important nowadays, especially for monitoring and control the home or industrial devices. The server enables Web access to distributed measurement/control systems and provides a scalable networking solution that is optimized for educational laboratories, instrumentation, Industrial and home automation. Existing system: In existing system, if the host needs to connect more serial devices at the same time with higher transmission rate and the data processing is more complex, the system performance is poor. In addition, these serial devices connect the same host may be geographically far and this will increase the length of wiring and drop communication quality. Proposed system: In the proposed system, GPRS technology is used. At first the GPRS Modem is configured for IP. The temperature sensor, gas sensor and humidity sensors are connected to the ARM Processor. These values are measured and transmitted through GPRS Modem. At the receiver end another modem is used to receive the data and it is uploaded into internet.
