Design of multi-point wireless multifunction monitoring system based on Android

The design of the multi-function wireless monitoring system based on Android is designed in this paper. The system consists of superior-machine and lower-machine. The lower-machine takes ATmega16 as the core processor, and RCV420 is the signal processor for measuring and sampling the 4-20mA current signal. The superior-machine is connected with lower-machine to receive and send data by WIFI module and acquire eight environmental real-time variables. The superior-machine is based on Android Development Environment and Javascript which uses Client to obtain real-time variables and gets with function such as curve display, data saving and warning prompt. The system can obtain an value of scale 2048 points by setting the ID number. The field experiment and application shows that this system has good performance in remote monitoring of the multi-point environmental values and industrial production with high accuracy and real-time requirement.
