摘　　要： 介绍了一种基于当前多通道的毛细管电泳芯片的发展基础上,双单片机控制和通讯系统的设计与实现。通过串行或并行总线机制来开发系统的并行性,提高了对当前高数据量芯片的处理和实时通讯的速度,简化电路设计,可独立灵活地控制分离和进样时间,电压等条件。有利于实现微全分析系统的高效化、集成化,易控制,降低干扰,适合野外数据采集和检测。 Based on recent development of the multi-channel capillary electrophoresis（CE）chip,a design and realization of the double single-chip processor control and communication system is introduced.Through the serial or parallel bus mechanism, the parallel of the system has been developed, which improves the processing velocity and real-time communication of the high data-capacity chip. Furthermore, this approach simplifies the design of the circuit,which can be also used to control flexibly the separation, sample injection time,driving voltage etc. of the micro-capillary eleetrophoresis. Optimization of the protocol could results in increased efficiency and easy to control, by the integration of the μTAS （ Micro Total Analysis Systems ）.With increased signal to noise ratio, the system is more suitable to field applications on data collection and detection.
