Design of intelligent gas monitoring terminals of mobile communication system
Abstract
Intelligent monitor Terminal is primarily responsible for information about real time smoke and gas concentrations, can transfer information via the WIFI module to monitor in real time on a Smartphone, you can also view data in real time via the WEB page, and set the sensor parameters. In addition, the intelligent monitor Terminal monitor to smoke or when the gas concentration exceeds a threshold, not only sound and light alarm, call preset call can also use GPRS module. ANDROID Smartphone via WIFI module for wireless communication with the Terminal. Can get to smoke and gas concentration data in real time, and allows you to record the data, display data, and can set sensor alarm threshold parameters. Produce a threshold alert, there are several mobile phone reminders.
This paper completed the expected idea, the design of a hardware circuit and the writing and debugging of system software. The test results prove that meets the design requirements.
