Embodiment Construction

[0012] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0013] The mobile stand-alone DGPS anti-collision system in the bulk cargo terminal yard is installed on the DGPS reference station in a fixed place on the ground to provide the spatial position data information of the reference station and process the spatial position data information from the mobile sub-stations on each stand-alone; In the mobile station of each mobile stand-alone, it is used to measure the real-time data information of the spatial position during the movement of each stand-alone; the communication system is used for the networking between each stand-alone rover and the DGPS reference station, and between the DGPS reference station and the PLC system data communication; the PLC system installed in a fixed place on the ground is used to receive the data of the DGPS reference station, and logically process the data according to the space anti-collisio...

Abstract

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.

Description

technical field [0001] The invention relates to a mobile stand-alone anti-collision system, in particular to a DGPS anti-collision system used between mobile stand-alone machines in a port bulk cargo yard. Background technique [0002] With the continuous improvement of port bulk cargo terminal management requirements, the safety requirements for equipment and property safety are also constantly increasing. In order to improve the operation efficiency and flexibility, the process layout of the bulk cargo yard in the modern port has multiple mobile stand-alone machines (stackers, reclaimers, stacker-reclaimers) working together in the same yard, and the movement between stand-alone machines There is a high risk of collision. The cost of each single machine is as high as 30 to 40 million yuan. Once a collision occurs, it will cause serious machine damage and personal casualties, and affect the normal operation and production, bringing huge economic losses to the enterprise. ...
