Design And Implementation Of The Android Platform Based On Hard Intercom System

Android operating system is one of the most popular embedded operating system. Based onthe Android platform is open source, development environment, high integration characteristic,combining SA808high integrated talkback module, the design and implement of hard intercomsystem. Talkback mobile phone hard intercom system is applied to the Android system, realizedthe transceiver function, has off intercom, intercom, customized group parameter configurationfunction.Hard intercom system combines JNI, SqLite, serial communication technology, SA808implementation and high integrated talkback module communication, configuration parameters ofhardware module, and an audio signal acquisition, coding and transmission, realize theintercommunication function. System using JNI technology and Realization of direct interactiondriven application layer; using SqLite database to store intercom parameters, group information; torealize the communication application layer and the serial port using Serialport the Api open sourceinterface. The system can real-time change the intercom module, packet function, also is thecustom group functions. System software interface provides a switch button, only need to slide onthe mobile phone screen switch, can realize the opening or closing the intercom module function.Hard intercom system integrated into the intercom mobile phone, mobile phone use intercomintercom function is more flexible and convenient. Because the system is developed on theplatform of Android, which is running in the intelligent mobile phone, so the system integrationdegree is high, the operation is also very convenient, call quality and performance of the intercomto make. Talkback mobile phone is a phone, mobile phone is a fully functional, system availabilitygreatly improve mobile phone talkback.
