Orienteering Timing System Based on Sub-G Band Wireless Sensor Network

Orienteering is a long-distance outdoor sport, in which electronic timing system plays an important role. However, the current production of electronic timing equipment technology on the Chinese market is still less developed in weight, volume, power consumption and other technical indicators compared with the international manufacturers in advanced level. Non-contact timer still has a big gap, and the price is too expensive, bulky and lack of portability. In order to solve this problems and improve the quality of directional movement of electronic timing equipment, this article adopted the new SoC as a master plan, design and implement a set of low power consumption, low cost, portable and reliable directional movement of the timing system, innovating the NFC tags and Sub-G communications functions.
