A DGPS (differential global positioning system) anti-collision system of mobile machines of a bulk cargo terminal storage yard comprises a DGPS base station, moving stations of the mobile machines, a communication system, a PLC (programmable logic controller) system and a man-machine interface. The DGPS base station is bidirectionally connected with the PLC system, the PLC system is bidirectionally connected with the man-machine interface, the output end of the communication system is connected with the input end of the DGPS base station, and the output ends of the moving stations of the mobile machines are connected with the input end of the communication system. By the Ethernet, the moving stations are connected with the DGPS base station to form an independent DGPS measuring system, the DGPS system is in data interaction with the PLC system in a hardware configuration manner, and the PLC system can perform logic operation of DGPS data according to the space anti-collision algorithm model; according to different results, risk anticipating and warning of travelling, pitching and rotation of the mobile machines can be realized as well as anti-collision control between the mobile machines of the integral storage yard.
