Abstract

The invention discloses a system and method for positioning an overhead crane. According to the invention, the system based on RFID (Frequency Identification) and a WIA (Wireless Network for Industrial Automation) is adopted and mainly comprises a positioning electronic tag, an RFID integrated reader-writer, a WIA wireless gateway and an industrial control computer. The system has the characteristics of accuracy in positioning, wide adaptation scope, higher flexibility, long wireless transmission distance, simplicity in installation and adjustment, no need of wiring, and the like. According to the system, the electronic tag serves as a beacon which corresponds to the position of the overhead crane, the reader-writer serves as an information acquisition device during overhead crane moving, the current position data of the overhead crane is transmitted to the WIA wireless gateway through the wireless communication protocol of the WIA, the wireless gateway transmits the positioning information to the industrial control computer, and the industrial control computer processes the data to obtain the current position of the overhead crane.

Description

technical field [0001] The invention relates to the technical field of crane positioning, in particular to a crane positioning system and a positioning method based on RFID and WIA wireless network systems. Background technique [0002] With the acceleration of informatization construction in major iron and steel enterprises in recent years, ERP and MES information management systems have been widely used. In this way, higher requirements are put forward for iron and steel making, steel making, hot rolling, cold rolling and warehouse logistics links of medium and heavy plates in iron and steel enterprises. At present, the commonly used crane positioning methods are mainly manual positioning or the method of installing an encoder and a laser positioning system on the crane wheel axle. Different colors of the color bar represent different positions. The operator of the crane can know the current position by observing the color bar of the corresponding color. This requires the...
