Embodiment Construction

[0035] The present invention will be further described in detail below through the specific examples, the following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present invention with this.

[0036] like figure 2 , the present invention claims a dangerous goods tanker curve speeding warning system, the system includes: vehicle information collection module 4, weather condition module 1, central control module 3, display module 2.

[0037] The vehicle information collection module 4 adopts a radio frequency identification technology RFID reader for collecting information on dangerous goods transport vehicles 5 equipped with radio frequency identification tags and recording vehicle and cargo information; the collection process takes a short time to ensure the accuracy and accuracy of the system reliability.

[0038] The central control module, through real-time collection of temperature and humidity information, identifies weathe...

Abstract

The invention discloses a method for acquiring the safe travel speed of a dangerous goods tank car on a curved road and an overspeed warning system. The system comprises a vehicle information acquiring module, a weather condition module, a central control module and a display module. Based on statistic analysis of the type and reason of accidents during tank road transportation of dangerous goods on a curved road, indexes affecting vehicle control are comprehensively selected. The method and system have the advantages that calculation is easy, calculation speed is high, reliability is high, cost is low, and support is provided for limiting the speed of the dangerous goods tank car to safe travel speed on a curved road.

Description

technical field [0001] The invention relates to the technical field of traffic safety, in particular to a method for obtaining a safe vehicle speed on a dangerous cargo tanker curve and an overspeed warning system. Background technique [0002] The statistics of dangerous goods transportation accidents on the road show that the curved road section is a section with frequent traffic accidents, the main reason is that the speed is relatively high. , A rear-end collision occurs, or the direction is turned sharply, causing a rollover accident, or the vehicle loses control when skidding and flicking. [0003] When the vehicle is turning, especially the dangerous goods tanker driver is prone to risky overspeed driving. For emergencies in the blind spot of road vision, the probability of occurrence is low, so it is easy to be ignored by the driver. Driving only considers when the vehicle does not skid or sideways. Under the condition of overturning, the speed of the vehicle can be...
