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.
