LMI controllers orchestrate machine-vision applications
-- Test & Measurement World, 12/5/2008 9:00:00 AM
Using only two universal control modules for any installation, LMI Technologies’ Maestro system simplifies the task of connecting the various components of a machine-vision system. It is compatible with all cameras and light sources, as well as all machine-vision-software libraries, and uses simple CAT5e cabling.
A Maestro configuration comprises two modules: the P800 master controller and the C12 camera and light controller. The P800 interfaces with the encoders and the I/O, delivering microsecond synchronization over CAT5e cables for up to eight cameras and light sources, all from a single power supply. All timing, triggering synchronization, sorting, and reject activations are completed by the maestro P800 module.
Devices are slaves to the P800 controller, including the host computer that performs image processing. Camera image data is delivered directly to the host computer via standard interfaces, such as GigE Vision or IEEE 1349, with all timing dictated by the P800 and communicated to the host computer via Gigabit Ethernet.
The second module, the C12 camera and light controller, connects to the P800 with CAT5e cable at a maximum distance of 100 m. It powers and triggers any camera, while providing synchronized, configurable high-current pulses for LEDs or lasers.
Configuration of a Maestro system is accomplished using TCP/IP and XML or optionally with a Web-based browser for stand-alone operation. You can also integrate LMI’s FireSync, Sensors that See, and Hexsight components with standard camera and lighting components.
