The latest signal time-of-flight positioning technology developed by Shenzhen Yiri Technology Co., Ltd., combined with the three-dimensional information display platform, has independently developed a new generation of positioning technology on the basis of the second-generation field-strength positioning ZigBee technology. It has all the advantages of field-strength positioning, measuring 96% of the errors between the distance and the actual distance are within 3 meters.

From July to December 2011, the company successively obtained relevant "Mining Product Safety Mark Certificates", including mining explosion-proof and intrinsically safe DC regulated current, identification card, transmission interface, mining wireless communication system, mining intrinsically safe Type card reading auxiliary station, mine intrinsically safe information transmission substation, mine intrinsically safe card reader master station, mine intrinsically safe communication base station, mine intrinsically safe communication substation, mine intrinsically safe data acquisition equipment, coal mine personnel management system and other products.

The next day technology will continue to pay close attention to the high-tech core, carry forward the spirit of independent research and development, continuously improve the strength of the professional team, and make due contributions to the high-tech of the motherland.
