1. A non-blind area real-time monitoring and alarming system for an accident on a freeway, comprising:
a road detection unit;
a monitoring signal processing unit; and
a locating and patrolling unit that are located in different monitoring areas,
wherein the road detection unit comprises a distributed sound wave detection fiber-optic cable that is disposed on a freeway guardrail and used for distributed online monitoring of collision sound upon occurrence of a traffic accident;
wherein the monitoring signal processing unit comprises a fiber-optic sound wave demodulator;
wherein the locating and patrolling unit comprises a workstation, a monitoring terminal and a drone that coordinate with one another;
wherein data is shared between different monitoring areas by means of a data transmission unit that comprises a network switch to form an integrated sensing monitoring network, and
wherein an output end of the distributed sound wave detection fiber-optic cable is connected to an input end of the fiber-optic sound wave demodulator, and
wherein an output end of the fiber-optic sound wave demodulator is connected to input ends of the monitoring terminal and the workstation.
