The Design Of Wireless Network Control Terminal Based On Mobil Phone Platform

As is well-known, the number of users who can communicate through the wireless internet is becoming much more then ever due to the rise of the mobile internet.In addition, the concept of Internet of Things is becoming the favor of various fields, especially the work environment without person. Even though currently there are some mature products that support remote control have been applied to industrial control, smart home, remote meter reading domestic or abord, there still exists several disadvantages such as expensive prize, single faction, deep reliance on the PC and complex wiring. So, it’s urgent to develop a set of products be used to control the remote devices anytime and anywhere.This article adopts the highly integrated mobile phone modules as the total control terminal of the remote control with the help of GSM, MMS, multimedia, blue tooth, infrared and other modules’ communication and date acquisition function. Meanwhile the author takes the secondary experiment of port expansion,load matching and diver design, with the purpose of shorten the development cycle and reduce the costs.Designed a overall block diagram based on the MTK platform considering the similar products domestic or abord and made a comprehensive evaluation about the mainstream of hardware and software platform.Introduced the hardware and software system of MTK in detail. The operating system of MTK and each functional module like NVRAM, GPIO, send or receive SMS and software system code are also described detailedly, in order to lay a soiled foundation of the secondary development.Introduced the establishment process of the secondary development and described the realization processes of send or receive message, GPIO port driver, table lamp driver, infrared senor signal receiving circuit.The experiment results show that the wireless network control terminal system based on MTK platform have achieved good performance on cost-effective and flexibility, which make up for the inadequacy of existing systems. It is worth promoting.
