Road area safety warning control system

Abstract

The invention relates to a road area safety warning control system which comprises an on-board control device, a road side unit and a cloud server, the road side unit corresponds to coordinate data and is provided with a wireless communication range, the road side unit is connected with the on-board control device entering the wireless communication range of the road side unit, and the cloud server stores the coordinate data of the road side unit and sends the coordinate data to the on-board control device. The method comprises the steps that a cloud server receives event coordinate data and collects event coordinate data and event information, the cloud server defines at least one road side unit as a matched road side unit according to the event coordinate data, the cloud server divides the event information into a plurality of grades, and correspondingly outputs a speed control instruction to the matched road side unit according to the grades; and the matched road side unit transmits the speed control instruction to the on-board control device entering the wireless communication range of the road side unit, so that the effects of warning and speed control are achieved.

Description

technical field [0001] The present invention relates to a warning control system, in particular to a road area safety warning control system. Background technique [0002] Vehicles such as automobiles and motorcycles are quite common means of transportation. Only when vehicles are driving on the road, they will always encounter various road conditions, such as traffic accidents, traffic jams and traffic control. These road conditions may affect the driver's itinerary. In order to improve the aforementioned problems, the prior art provides a road condition reminder function, which can display the road conditions near the driver to the driver through a user device (such as a smartphone or a navigator) for inspection, and the driver can determine whether to change lanes according to the nearby road conditions. For example, Taiwan Patent No. I610276 discloses a GPS regional road condition reminder system, which is mainly loaded with a regional road condition reminder application...

Problems solved by technology

[0003] However, when the driver operates the vehicle, he must focus most of his attention on the road conditions ahead and the surrounding road conditions, and the road conditions are diverse and may occur at any time. The driver may not be able to immediately perceive the road condition reminder information provided by the existing technology. When the road conditions in front of the driver occur, such as a major disaster or traffic control, the driver may continue to go without noticing the road condition reminder information provided by the existing technology, resulting in the impact of the major disaster or traffic control on his trip
