The Freeway Conditions real-time monitoring device is protected along the corrugated sheet guardrail (2) or concrete of Expressway Central Strip In column (25) walking process, the video acquisition module (6) carries out video capture to Freeway Conditions and is transferred to microcontroller Device module (3), by Freeway Conditions video, module (5) is transferred to monitoring center to micro controller module (3) by radio communication Computer, the monitoring center computer carries out analyzing processing judgement to Freeway Conditions video, when being judged as highway When there is disease on road surface, sends the information that the Freeway Conditions real-time monitoring device stops walking and gives micro controller module (3), Micro controller module (3) controls the first motor driver (15) and stops the first electro-motor of driving (13), and controls the second motor Driver (16) stops the second electro-motor of driving (14), and the Freeway Conditions real-time monitoring device stops walking, described Video acquisition module (6) carries out video capture to Freeway Conditions herein again and is transferred to micro controller module (3)；Together When, the micro controller module (3) acquires the highway location information that locating module (7) navigates to and is transferred to microcontroller Module (3), by the highway location information navigated to, module (5) is transferred to prison to micro controller module (3) by radio communication Central computer is controlled, position and the map of the highway for pavement disease occur are shown on the monitoring center computer；Meanwhile The micro controller module (3) also control voice playing module (8) sends out voice reminder or caution signal, reminds by there is road The vehicle deceleration of the highway of face disease goes slowly or detours.
