GPS-based Modbus anticollision system

TST develops for the industrial group TSK, a GPS-based positioning system with Modbus RTU communications to avoid collisions between mobile arms of heavy machinery at an outdoor stone quarry in Morocco.

The new device, based on the innovative platform TSmarT, is remotely reading geo-coordinates based on GPS technology and connects to a control PLC via RS-485 Thus, the PLC receives the coordinates of the GPS devices and calculates the distance between them, sending a stop command in case of not respecting a minimum safety distance.
