title: [A rapid fetal ECG acquisition system based on FT245RL].
abstract: A rapid fetal ECG signal acquisition system is designed, which includes three modules: a front-end signal acquisition module, a micro control module and a PC software application module. The first two modules are accomplished through the ADS1294 and the STM32F103 chips, respectively, and the third one is developed in VC++ platform. By using the FT245RL chip, the proposed system implements the serial-parallel conversion communication between ARM and PC, improving the data transmission rate largely. Also, it has a simple structure, with low power consumption and high precision. Furthermore, it can collect fetal ECG signals from mother's abdominal wall and convert them into the 24-bit digital signals.
