Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is carried out clear, complete description.Obviously, described embodiment only is part embodiment of the present invention, but not whole embodiment.Based on the embodiment among the present invention, the every other embodiment that those of ordinary skills obtain under the prerequisite of not making creative work belongs to the scope of protection of the invention.
Fig. 1 carries the structural drawing of apparatus embodiments one for CTCS-3 level row of the present invention car controlling, as shown in Figure 1, the equipment of present embodiment can comprise: security control computer module 10, the range finder module 11 that tests the speed, wireless communication module 12, transponder receiver module 13, track circuit read module 14, Train Control interface module 16 and human-computer interaction module 15.
Security control computer module 10 is connected with the range finder module 11 that tests the speed, wireless communication module 12, transponder receiver module 13, track circuit read module 14, Train Control interface module 16 and human-computer interaction module 15 respectively.
The range finder module 11 that tests the speed is used for obtaining velocity information and the distance travelled information of current train.
For instance, the range finder module 11 that tests the speed can be connected with tachogenerator, can obtain train present speed information and the distance travelled information of train in real time, security control computer module 10 can be according to these two information, the real-time running status of monitoring train, and instruct and train carried out concrete operations such as speed limit by generating car controlling.
Preferably, the range finder module 11 that tests the speed can be connected with the radar velocity measurement sensor, obtains velocity information and the distance travelled information of current train by the radar velocity measurement sensor.
For instance, the precision height of radar velocity measurement sensor, measurement data can adapt to the demand that highest running speed surpasses the bullet train of 350km/h accurately and reliably, and its measurement result is not subjected to train wheel idle running or skids, and the influence that directly is worth of vehicle wheel.The range finder module 11 that tests the speed can obtain accurate velocity information and distance travelled information by the radar velocity measurement sensor, carries security and the reliability of equipment thereby improve the car controlling of CTCS-3 level row, and then can ensure the operation of train smooth safety.
For instance, wireless communication module 12 receives the row control information such as driving permission that send from the radio block center in the row control uphole equipment by GSM-R (GSM for Railway) wireless communication networks, and the row control information that will receive is transferred to security control computer module 10, generates car controlling instruction for it.Wireless communication module 12 also sends to radio block center according to train position information and the operational mode information that the current running status of train generates by the GSM-R wireless communication networks with security control computer module 10.So just realize the message exchange with the radio block center, thereby can make the radio block center running status current according to train, adjusted the row control information of sending to train in real time, and then effective guarantee driving safety.
In order to ensure the communication security of wireless communication module 12 and GSM-R wireless communication networks, have general encryption device in the wireless communication module 12, general encryption device has identical key with the radio block center.Before carrying out communication, security control computer module 10 generates the random number that is used for this communication according to key, and the ID that carries equipment together with the car controlling of CTCS-3 level row is encapsulated as first packet, and sends to the radio block center by wireless communication module 12.After the radio block center receives first packet, can obtain this random number, and data such as radio block center ID and random number are encapsulated, generate second packet by key and authentication arithmetic again, second packet is sent to wireless communication module 12, be transmitted to security control computer module 10 by wireless communication module 12.Security control computer module 10 is decrypted second packet by key, with data such as acquisition radio block center ID and random numbers, thereby finishes authentication verification for the first time.Security control computer module 10 generates the 3rd packet by data such as radio block center ID and random number and key more subsequently, and the 3rd packet sent to the radio block center, the radio block center is according to the check results of the 3rd packet, corresponding to security control computer module 10 transmission authorization data packets, finishing whole authentication process, security control computer module 10 has just been set up safe the connection by between wireless communication module 12 and the radio block center.
After safety connects foundation, row control exchanges data between wireless communication module 12 and the radio block center all needs to carry out corresponding encryption and decryption by key data and corresponding cryptographic algorithm, thereby security and the reliability of row control data are transmitted in the connection that can ensure safety effectively.
For instance, transponder receiver module 13 receives 1023 transponder message of transponder or the transmission of transponder group, be transponder information, and the transponder message that receives is carried out verification decode, be converted into 830 user's message, afterwards decoded user's message is sent to security control computer module 10, obtain corresponding row control information for security control computer module 10 by user's message, allow travelling speed information and line slope information etc. as circuit, security control computer module 10 just can generate corresponding car controlling instruction according to these information, thus guarantee driving safety effectively.
