Abstract With development of sensor and embedded technology, more and more embedded intelligent devices appear in the public field of vision。 At the same time, the Android system become the most popular operating system in the mobile due to its open and development convenience。 These characteristics of Android make it become the best choice for developers to develop all kinds of mobile clients。 The title of subject is Smartcar Bluetooth Measurement and Control System based on Android。 The system use Android as the running platform of upper computer。 The upper computer will connect the Bluetooth module of lower computer by mobile phone Bluetooth。 The upper computer will control the smart car as well as get the camera data from the smart car through Bluetooth connect。

The lower computer of the Smart Car Bluetooth Measurement and Control System based on Android adopts KL26ARM Cortex-M0+ which is designed by Freescale  (NXP) as the main control unit。 We can receive command of the upper computer and control both the speed and the direction of the smart car。 The system use Android as the develop platform of the upper computer。 We can update the UI and handle the data at the same time by using the multi threading technology。 Bluetooth is used as the upper and  lower computer communication means to realize the real-time interaction and transmission of data。

This design will contain the software and hardware design and the theory of all parts of the system。 The content will include design of the overall system, the mechanical structure design, the control circuit board design, the selection and installation of sensor and control module, the smart car software design and the mobile APP design。 After repeated tests, it can be proved that this system is very stability。 The design has a certain reference value for the future of wireless measurement and control system as well as intelligent vehicle。
