Wireless communication system and method for stacker-reclaimer

Abstract

The invention relates to a wireless communication system and a method for a stacker-reclaimer, and belongs to the field of Ethernet communication. The wireless communication system of the stacker-reclaimer comprises a vehicle-mounted directional antenna which is arranged on the stacker-reclaimer through a vehicle-mounted antenna support, is connected with a vehicle-mounted wireless access point and is accessed to a vehicle-mounted Ethernet through a wired cable or an optical cable; a ground directional antenna which is arranged at the end point of a running track of the stacker-reclaimer through a ground antenna bracket; wherein the vehicle-mounted directional antenna is connected with a ground wireless access point and is accessed to the ground Ethernet through wired connection, the vehicle-mounted directional antenna and the ground directional antenna are oppositely arranged, and a plane center vertical line of the vehicle-mounted directional antenna and a plane center vertical lineof the ground directional antenna are overlapped with a virtual reference line. According to the stacker-reclaimer wireless communication system, the number of involved devices is the smallest, the cost is the lowest, maintenance is the most convenient, and stable and effective transmission of data is achieved.

Description

technical field [0001] The invention relates to the field of Ethernet communication, in particular to a stacker-reclaimer wireless communication system and method. Background technique [0002] Stacker-reclaimer, also called bucket wheel stacker-reclaimer, stacker and reclaimer, is a new type of high-efficiency continuous loading and unloading machine. It is mainly used for loading and unloading iron ore (sand), coal, sand, etc. The machine is widely used at home and abroad because of its high operating efficiency. [0003] The stacker-reclaimer uses a towing cable to provide power and communication connections for the stacker-reclaimer. The control system uses two types of cables to realize the data connection between the mobile stacker-reclaimer and the ground control system: [0004] 1. Industrial cables are used to connect the switching contacts between the on-board PLC of the stacker-reclaimer and the ground PLC control system; [0005] 2. Ethernet cables transmit co...

Problems solved by technology

However, these attempts are all due to the low wireless communication rate, unstable data transmission, and long data transmission lag time, so the wireless Ethernet communication system cannot completely independently undertake the Ethernet communication task between the vehicle and the ground.

Although some stackers and reclaimers are equipped with wireless communication equipment, they still have to rely on wired optical cables to perform data transmission tasks. The test results should be a complete failure.
