Emergency Warning System

An emergency warning system comprising :

• many delineators with individually unique IDs installed in regular intervals on medians or guardrails, grouped into zone and having reflective panels and LED lights;
• a low energy Bluetooth module, which is equipped in the delineators, that transmits a beacon signal which includes an emergency warning signal, to nearby delineators in relay and sends emergency warning signals as push notifications to nearby drivers' smartphone S1;
• an internet of things communication module, which is equipped in the first delineator(top repeater) and the last delineator(bottom repeater) within the zone in the direction of driving, that receives control signals from the delineators in the same zone and sends beacon signals via internet of things communication with a central control server:
• a bottom repeater that collects emergency warning information and transmits the information to the central control server through the internet of things communication module when the emergency warning signals are received in relay from the low energy Bluetooth module;
• and,
• a central control server that processes the received emergency warning information, connects with cell service providers, and sends the processed emergency warning information as push notifications to smartphone S2 of drivers behind the location of the accident;
• wherein the beacon signals among the near low energy Bluetooth modules are transmitted in an one-directional relay from the top (ahead in the direction of driving) to the bottom (behind in the direction of driving), the state control of each delineator transmits control signals from the top repeater to the bottom repeater within the same zone according to the central control server's remote control,
• wherein the delineators further include vibration sensors, the bottom delineator collects the vibration information detected by the vibration sensors and transmits the collected information to the central control server, which determines if similar patterns of vibration are detected in the same zone by analyzing the vibration information of each zone, detects strong rain, strong wind, and typhoons, transmits caution signal to the top repeater in the same zone, and activates the flickering of each delineator's LED later when each of lower delineators in the same zone receives the information in relay by the low energy Bluetooth modules.
