Study on the Control System of Microarrayer

The control system is the key parts of microarrayer. The working process and configuration of microarrayer are introduced briefly. Special attention is paid to the analysis and computation method of the working path in microarray fabrication. On the condition of given parameters, such as sample variety, slip quantity, spot matrix module, pin matrix module etc., the working path has been mainly divided into two main subpath, such as Z axis pin path, XY axis spotting path. Then the tree classing method has been taken to calculate the working path with the given parameters. The method and expressions are presented in details. In terms of working path planning of microarrayer, a control system based on LM628 and AC serve driver are implemented successfully. The hardware and software of the system are discussed in details. The agreement of the final computation results with the experimental data indicates the method could be used to estimate the working path of microarrayer quickly and effectively at engineering analyses. The control system are robust and effective
