Control method of rail traffic infrared video frequency transmission system

[0038] The control method of the infrared video transmission system when the track is a straight line:

[0039] Such as Figure 6 Shown is the working principle diagram of the infrared video transmission system when the track is a straight line. The camera is installed on the platform; the image synthesizer and modulator are installed in the communication room; the infrared video receiver is installed behind the windshield of the locomotive cab. It is installed towards the direction of train movement. The monitor is installed on the left side of the bridge, and the infrared video transmitter needs to be installed on the pillars or walls beside the tracks at both ends of the platform. The installation height should be the same as that of the infrared video receiver on the locomotive, about 2 meters above, to prevent being blocked by people , detector 1 is installed 100 meters before the parking position of the platform, and detector 2 is installed 100 meters behind the parking po

[0041] The control method of the infrared video transmission system when the track is a curve:

[0042] Such as Figure 7 As shown, it is the working principle diagram of the infrared video transmission system when the track is a curve. N detectors are installed beside the curved track. The first detector is responsible for starting the first infrared video transmitter, and the second detector is responsible for The shutdown of the first infrared transmitter and the startup of the second infrared transmitter, and so on, the Nth detector is responsible for the shutdown of the Nth infrared video transmitter. The distance between the detectors depends on the size of the arc, the more curved the arc, the denser the detectors are packed. The locomotive detector makes the infrared video transmitter be in the relay working state like this. Other methods are the same as in Example 1.
