Design of multi-detectors imaging control system based on field bus

A higher performance control system of multi-detectors imaging has been implemented on opto-electronic imaging tracking and measuring device. Combined with the advantages of field bus and distributed control, we develop this control system based on CAN bus. The field control node uses DSP chip TMS320F2812 to support the imaging motor control, sensor control, temperature measurement and control, etc. We design a real-time communication protocol to meet the data transmission on the system control network, and this protocol can apply other device with little change. On the remote host computer, a main control software programmed with VC++ monitors and control the imaging system. Test results and application in devices note that this system is stable and reliable, and it can be promoted to more opto-electronic imaging tracking and measurement devices.
