中文摘要：

For the issue of nuclear radiation detection,this paper designs a remote control nuclear radiation detector which can trace a pre-determined route,avoid obstacles effectively,and can be controlled remotely by users wirelessly or through voice command.It can effectively replace manual probing due to convenience,flexibility and safety.The system mainly consists of a nuclear detection module,a voice control module,a route tracing module,an obstacle avoidance module,a data transmission module,storage and a display module,and a D.C.machine.An MSP430 microcontroller is used as a control chip to control the motor and the system uses infrared technology and ultrasonic sensors to achieve intelligent tracing and obstacle avoidance.Moreover,it applies a voice module and data transmission module to remotely controlling the device.The radiation data is shown on an LCD screen.

For the issue of nuclear radiation detection, this paper designs a remote control nuclear radiation detector which can trace a pre-determined route, avoid obstacles effectively, and can be controlled remotely by users wirelessly or through voice command. It can effectively replace manual probing due to convenience, flexibility and safety. The system mainly consists of a nuclear detection module, a voice control module, a route tracing module, an obstacle avoidance module, a data trans- mission module, storage and a display module, and a D. C. machine. An MSP430 microcontroller is used as a control chip to control the motor and the system uses infrared technology and ultrasonic sensors to achieve intelligent tracing and obstacle avoidance. Moreover, it applies a voice module and data trans- mission module to remotely controlling the device. The radiation data is shown on an LCD screen.
