Abstract:Have the STC12LE5A60S2 MCU as the core; the recorder can achieve the record of parameters, such as the running track, by the connecting of GPS module card, SD card, LCD and voice module. And this paper elaborates and explains the recorder’s composition, function and the design idea of its hardware and software. This recorder can record real-time running track of vehicles or ships. According to the setting of position and velocity, this recorder can also provides real-time detection and automated voice prompts. The setting of position, velocity and voice information can be modified conveniently, and which can be exchange with PC through the USB communication. In addition to that, the recorded information can be used for the reproduction and analysis of the vehicles and ship’s process of moving. This recorder has large storage capacity, without loss of data even if power off, and easy to use.
