Abstract
The invention discloses a foreign matter invading system for train environment in the field of train running systems. The system comprises a video image collecting and processing module, wherein a signal output terminal of the video image collecting and processing module is connected with a signal input terminal of a video data image transmission module, a signal output terminal of the video data image transmission module is connected with a signal input terminal of a microprocessor, and a signal output terminal of the microprocessor is connected with a signal input terminal of an alarm unit. The running route of a train is monitored in a real-time video manner, so that the security of the running of the train is improved. The system can be used for the running of the train.
Description
Technical field
The present invention relates to a kind of train driving system, particularly a kind of train safe driving system.
Background technology
Along with the fast development of China's economic society, railway passenger and freight transportation amount constantly increases, and train running speed improves constantly, and to railway security, monitoring brings huge pressure, and wherein railway foreign body intrusion badly influences the safe in operation of train.Because the train middle environmental factor of running at high speed is in the open unpredictable, track foreign body intrusion may have serious consequences to traffic safety.Track foreign matter refers to the obstacle that has influence on normal traffic safety on railway, the suspension that on the road causing as landslide, mud-rock flow landslide etc., sandstone, bridge tunnel drop, is still trapped in work business personnel and the associated equipment of operation because of the error of reporting to the police.Due to requirements such as high-speed, the low loss of railway foreign body intrusion checking system, low rate of false alarms, make traditional take the IDS that software is core and be faced with the increasing pressure, only depending on the improvement of pattern matching algorithm is limited to the raising of intrusion detection speed, is not the basic strategy of dealing with problems.
Summary of the invention
The object of this invention is to provide a kind of train environment foreign body intrusion system, improve the safety of train operation.
The object of the present invention is achieved like this: a kind of train environment foreign body intrusion system, comprise Video Image Processing module, the signal output part of described Video Image Processing module is connected with the signal input part of image of video data transport module, the signal output part of described image of video data transport module is connected with the signal input part of microprocessor, and the signal output part of described microprocessor is connected with the signal input part of alarm module.
As a further improvement on the present invention, described video acquisition processing module comprises A/D converting unit, the signal output part of A/D converting unit is connected with the signal input part of Video Decoder, the signal output part of described Video Decoder is connected with the signal input part of buffer unit, and the signal output part of described buffer unit is connected with the signal input part of transmission of video images module.
As a further improvement on the present invention, described A/D converting unit is selected ADV7181B chip.
As improvement of the present invention, described image of video data processing module is selected DM9000A network controller.
When the present invention works, system adopts ADV7181B to complete analog video decoder and processes, complete analog video signal to the conversion of YCrCb digital signal, because the video data gathering is mass data, this has all brought very large inconvenience to storage and transmission, need to carry out pretreatment to video data, to reduce data volume, system is stored in decoded digital signal in cache module, finally data are sent to train controlling center by network, if system detects extremely, sending controling instruction is to alarm unit, to remind in time train driving personnel in time.Compared with prior art, beneficial effect of the present invention is, the present invention, by train driving route is carried out to real-time video monitoring, has improved the safety of train operation.The present invention can be used in train driving.
Accompanying drawing explanation
Fig. 1 is control principle block diagram of the present invention.
The specific embodiment
A kind of train environment foreign body intrusion system as shown in Figure 1, comprise Video Image Processing module, the signal output part of Video Image Processing module is connected with the signal input part of image of video data transport module, the signal output part of image of video data transport module is connected with the signal input part of microprocessor, the signal output part of microprocessor is connected with the signal input part of alarm module, video acquisition processing module comprises A/D converting unit, the signal output part of A/D converting unit is connected with the signal input part of Video Decoder, the signal output part of Video Decoder is connected with the signal input part of buffer unit, the signal output part of buffer unit is connected with the signal input part of transmission of video images module, A/D converting unit is selected ADV7181B chip, image of video data processing module is selected DM9000A network controller.
When the present invention works, system adopts ADV7181B to complete analog video decoder and processes, complete analog video signal to the conversion of YCrCb digital signal, because the video data gathering is mass data, this has all brought very large inconvenience to storage and transmission, need to carry out pretreatment to video data, to reduce data volume, system is stored in decoded digital signal in cache module, finally data are sent to train controlling center by network, if system detects extremely, sending controling instruction is to alarm unit, to remind in time train driving personnel in time.
