Embodiment 2

[0123] All the other are identical with embodiment 1, described wireless communication and its communication standard, also can adopt WiMAX communication technology, be microwave access global interoperability (Worldwide Interoperability for MicrowaveAccess), it is a kind of emerging wireless metropolitan area network technology, it It can provide users with a transmission rate of 100M and can solve the mobility problem of broadband wireless communication. The communication protocol adopts the IEEE802.16e standard, which is the only broadband system in the WiMAX series standards that supports mobility and non-line-of-sight transmission. Provide solutions for high-speed transmission of video images.

Embodiment 3

[0125] The rest are the same as in Embodiment 1. The detection of the railway crossing signal mark object can also be realized by means of video detection signal lights. The position of the signal lights in the video image is constant and fixed in a small range. We You can pay attention to the state of the white light and the two red lights. If the white light is on, it means the crossing is open; if the two red lights flash alternately, it means the crossing is in the transition period from open to closed; Closed state; we can judge the state of the crossing by customizing the position of the signal light and detecting the brightness of a certain light of the signal light.

Abstract

The invention discloses an intelligent video monitor of railway crossing, which includes a video sensor that is arranged on the railway crossing and is capable of covering the traffic condition of the entire crossing as well as a monitoring computer that is used for monitoring the condition of the entire crossing and is capable of dynamic image understanding; wherein, the monitoring computer includes a video image collecting module, a displaying unit, an image pretreatment module, a railway crossing customizing module, a dynamic image understanding module used for analyzing the safety condition of the crossing, a video information saving module, a crossing wireless receiving and transmitting module and an issuing module of crossing safety information; wherein, the issuing module of crossing safety information is connected with a crossing displaying unit and an alarming sound playing unit; and the monitoring computer is connected with the wireless receiving and transmitting device. Theinvention has a high intelligence level and is capable of automatically judging various dangerous conditions or failures of the crossing through the image understanding technique and is also capable of mutual communication between the train driver and safety condition of the crossing as well as between the passengers and vehicles passing through the crossing and the train running condition through the wireless communication technique.

Description

technical field [0001] The invention relates to an intelligent video monitoring device for a railway crossing, in particular to an intelligent video monitoring device for a railway crossing based on dynamic image understanding and wireless communication technology. Background technique [0002] Railroad crossings have long been a weak link in railway safety. The frequent occurrence of crossing accidents directly threatens the life and property safety of the people and the economic transportation lifeline of the country. Today, after the railway speed is increased, the safety of railway crossings has increasingly become a bottleneck problem restricting the railway transportation capacity. A train running at a speed of more than 200 kilometers per hour will only take 9 seconds to reach a pedestrian at a distance of 500 meters. Once a pedestrian crosses the railway, it will be very dangerous. According to my country's current management level of railway crossings, crossing fac...
