Improving motorcycle anti-theft system with the use of Bluetooth Low Energy 4.0

Abstract

This paper proposes the improvement of motorcycle anti-theft system (MATS) utilizing Bluetooth Low Energy (BLE) 4.0. In the our previous work, the couple RFID passive tags were installed on motorcycles to detect the larceny conditions. The main problem was found in the last experiments that the RFID tags attached with the ignition key cannot be hung flexibly. Therefore, the BLE4.0, which is the low-power-consumption device, is dangle on the motorcycle's key and the RFID tags is installed on the bike's hidden body. The anti lost devices have been applied for responsibility of BLE-tags slave mode, installed on a key. The HM-11 BLE 4.0 module combination with an Arduino board has a function as the master mode, reading the MAC address (called ID) of BLE slave devices. The results show that the maximum distance, in which the BLE master module can detect the BLE slave's ID, is approximately 18 meters. The proposed method is reliable because the BLE devices can be hung on the key together while the motorbike is running on the speed not over than 80km/hr. Finally, the experimental results guarantee that, when relatively compared with the previous method, accuracy of the MATS is improved efficiently; moreover, this proposed system can actually be used in the real situation at the Prachinburi province, Thailand.
