The invention discloses a
control system for
a DNA (
Deoxyribose Nucleic Acid) sequencer, which comprises a PLC (
Programmable Logic Controller), controllers of first and second
servo motors, first and second peristaltic pumps and driving motors of first and second multipass reversing valves, wherein the controllers of the first and second
servo motors are electrically connected with the PLC; the first and second peristaltic pumps are respectively and electrically connected with the PLC and are used for receiving control signals of the PLC; a CCD (
Charge Coupled Device) camera is electrically connected with the PLC and is used for receiving a
control signal of the PLC; and a plurality of sensors are respectively and electrically connected with the PLC and are used for sending position signals of the
CCD camera to the PLC. According to the
control system disclosed by the invention, a
reagent supply
assembly of the
DNA sequencer with a plurality of reaction bins timely and accurately supplies reagents and
buffer solution for a plurality of reaction bins and the
CCD camera can be ensured to timely read an optical
signal in each reaction bin, and therefore, the aim of simultaneously performing a plurality of reactions is fulfilled, so that a plurality of samples can be simultaneously sequenced and the
DNA sequencing efficiency is greatly improved.
