METHOD FOR COLLISION AVOIDANCE AND REDUCING POWER CONSUMPTION BASED ON BLUETOOTH LOW ENERGY AND METHOD THEREOF

摘要

The present invention relates to a BLE beacon-based collision avoidance and power consumption reduction system. The present invention is applicable to a BLE scanner (BLE scan enable) that controls a short-range communication module so as to scan a BLE advertisement packet transmitted from the first through n-th BLE peripheral devices 200-1 through 200-n 100); And a BLE beacon, which is a device for transmitting the position and direction information by generating a promised signal at a predetermined cycle, and a BLE beacon corresponding to a signal generator based on the Bluetooth protocol based on IoT (Internet of Things) First to n th BLE peripherals 200-1 to 200-n; And BLE peripherals 200-1 to 200-n perform data BLE advertising on BLE peripherals 200-1 to 200-n in a region where BLE peripherals 200-1 to 200- The first to n-th BLE peripherals 200-1 to 200-n perform a uniform distribution between the set minimum time and the maximum time when performing an operation OFF operation to minimize the collision of the first to n- ), And does not perform BLE ad-tinging for the first to n-th random number times (rn_1 to rn-n) generated after the random number is generated. As a result, BLE adverting is performed, but BLE ad-typing is not performed for a random number time set to a uniform distribution after one execution, thereby providing an effect of avoiding a collision stochastically . Further, the present invention provides the effect of saving the power of the BLE device during the random number time by the random number time set in the continuous uniform distribution. In addition, the present invention significantly reduces the BLE ad-branding time of each BLE device on average, providing an advantage for low power applications.
