1.Gray Bus Position Detection Sensors

Gray bus precise positioning system communicates via electromagnetic coupler between flat-like gray bus and antenna box, and detecting the position of the antenna box in gray bus length direction when communicating. This system is a relatively mature displacement detection and data communication technology, non-contact absolute position detection, whose positioning precision is 2 mm. It can realize intermittent or continuous detection, especially applies in cart with uneven track or ring movement mechanical displacement detection, which is waterproof, grease proof and dustproof, and acid and alkali resistant.

The technology is aimed at large-scale industrial production automation for mobile machinery, which has a high degree of reliability and anti-interference ability. It is an effective means for realizing mobile device’s automatic contraposition and automatic control, significantly reducing energy consumption, improving product quality, reducing labor intensity as well as eliminating device crashes and improving production management. Our products have been applied in Wugang steel rolling heating device (Japan devices), Baogang Erlian crane positioning, Baogang continuous casting positioning, Baogang Erlianjiao locomotives positioning, railway container center station, port machinery and Metro positioning. Its features are as follows:

1. Non-contact operation;

2. Absolute position detection: it can detect continuously and accurately for an absolute address, the detect location precision is up to 2mm and can realize mobile locomotives automatic movement and fully automatic operation;

3. Extensive application range of communication

4. Out control of the Wireless Radio Management Committee

5. Good compatibility

6. Strong anti-interference ability

7. Suitable for harsh industrial environments: acid and alkali corrosion protection, protection class IP68, with long service life.

2.Three dimensional automatic positioning loading and uploading system of container

Gantry crane lifts (bridge) cart (axis X) and the car (axis Y) can achieve absolute position detection by adopting Gray bus positioning technology; and using the multi-turn type absolute encoder can achieve the detection of sling lifting height (axis Z), it mainly to address:

1. Gantry crane cart and trolley’s real time absolute position detection, accuracy is 2 mm;

2. Digital container yard

3. Adopting the real time location display and remote control room display on the gantry crane cart and trolley car

4. Adopting the real time location display and remote control room display on the container center

5. Gantry crane's best run path calculation

6. Gantry crane container anti-collision

7. Gantry crane automatically running

8. Automatic operation can improve operational efficiency of the system by 50% and pile utilization by 29%.
