When train according to traditional row control mode operation, or during driver's manual drive, vehicle-mounted train operation control convenience provides the crashproof function of evading to train, with the prompting emergency or evade and the conflicting of other vehicle.The crashproof function of evading is mainly for rail running train or the same rail train incorporated into through track switch, according to relative velocity, the distance of other relevant train, train braking performances etc. are calculated block section; When existing potential collision dangerous, Ben Che and relevant train are sent alarm prompt; If the interior driver of certain hour does not make correct processing (such as braking) to alarm after sending alarm, then vehicle-mounted train operation control convenience output emergency braking instruction is to the brake system of train, braking train.
In the control system of the present invention, the first communication device in each vehicle-mounted train operation control convenience and ground communications equipment consist of main communication system---a kind of Automatic dependent surveillance broadcast communication system of native system.This system is used for transmitting train operation control information, other relevant train information, adopts the broadcast operation mode, the repeatedly connection that can avoid handshaking type communication to bring, the drawback of point-to-point communication, have high real-time, and the communication data capacity is larger, satisfies the requirement of native system communication.Among the present invention, the broadcast type autocorrelation of the first communication device in each vehicle-mounted train operation control convenience monitors that wireless data chain communicator is comprised of data exchange module 19, data processing module 20, data transmit-receive module 21 and antenna 22, as shown in Figure 3.
The mobile unit that present embodiment provides and train operation control system, can also carry out the multidirectional transmission of car-ground and car-car information by the movement-based communication network, increase the remaining of wireless communication transmissions, improve the area coverage of reliability, real-time and the communication scope of communication.Can realize train running speed, Real Time Monitoring such as operation interval etc. under the high-speed cruising, realize the automatic control of train operation.
Train Positioning Technology among the present invention is another core of the present invention, and the directly precision of impact supervision, and then impact is to the operation control of train.Deposit current orbit information in the kilometer post among the present invention, comprised orbital number, mileage information, burst length, speed-limiting messages, track switch information etc.; If train reaches a threshold value in operational process middle distance the place ahead track switch distance, in the time of can't obtaining again the place ahead route information, control system control train stops before track switch, provides follow-up the continuing of command adapted thereto and sails until get access to the place ahead route information or row control center;
Ground communications equipment among the present invention and vehicle-mounted train operation control convenience both connected each other, and be separate again.During the ground communications equipment partial fault, train can obtain adjacent train information by the immediate data exchange of Che-Che, can ensure the safe in operation of train, and is less to the normal influence on system operation of train; Equally, during single vehicle-mounted train operation control convenience fault, the auxiliary supervision by means of the Che of other remaining-Che communication and ground communications equipment can guarantee train operating safety equally.
Based on control system of the present invention, the present invention further provides a kind of train operation control method of self adaptation obturation, comprising:
Adopt the train operation control system of above-mentioned self adaptation obturation, each train operation control convenience of train operation control system divides on the train that is located at the adjacent operation of same track;
Train is in operational process, the train operation control information is obtained in ground communications equipment communication connection by vehicle-mounted train operation control convenience and train operation control system, vehicle-mounted train operation control convenience and the vehicle-mounted train operation control convenience radio communication of rear adjacent train by vehicle-mounted described train operation control convenience and front adjacent train are obtained other relevant train information, obtain the run location information of train by vehicle-mounted described train operation control convenience, and obtain train operation state information by vehicle-mounted described train operation control convenience;
, according to described train operation control information, other relevant train information, the run location information of train, train operation state information the running state of train is controlled by train-installed described train operation control convenience.
In sum, the control system of embodiments of the invention has very strong adaptivity, is applicable to all grade railways, subway and subway.Simultaneously, the present invention is more flexible in actual application, namely can be used as complete train operation control system and uses, and also can simplify as the crashproof avoidance system of independent train and use.
Take " 7.23 " river in Zhejiang Province especially big railway traffic accident of temperature line as example, if train operation control system of the present invention has been installed, even then weather condition is abominable, even trackside signal facility et out of order, even it is proper that ground maneuvers is not commanded, rear car driver still can know clearly the residing position of front vehicles by the vehicle-mounted train operation control convenience among the present invention, gives a warning to the driver; Even the driver does not notice this situation, the vehicle-mounted train operation control convenience among the present invention also can be taked brake measure automatically, avoids car accident to occur.
In a word, the invention provides and a kind ofly can realize between the train monitoring each other and automatic train operation control system that ground monitors in the face of train, solving train " cannot see " to each other, operation relies on wayside equipment and ground control's problem fully, give train more initiative, car controlling power and responsibility are shifted to train more, make autonomous, the automatic operation of train become possibility, the transport power of maximizing performance railway in guarantee driving safety, safety and the efficient of raising railway transportation.
