The train approach warning system can resolve the technical problem of utilizing the GPS positioning technology, the GSM network and the train dispatching commanding system to determine whether trains approach operational areas or not and implement early warning.
Description
Technical field
The utility model belongs to construction of railways safety protection technique field.
Background technology
Train Dispatching Command System (TDCS) (TDCS) is the status information by the collecting device acquisition trajectory circuit at each station, thereby by judging and the following train position, monitors and command the system equipment of train operation.The station equipment of TDCS is concentrated the track circuit status information that obtains and is sent to TDCS control center.Therefore by obtaining the section under the run location of train and the information such as direction of train operation with the TDCS system interface.Above-mentioned Train Dispatching Command System (TDCS) only can obtain the section under the run location of train and the information such as direction of train operation, can not send early warning signal to track operating area along the line by actv., to guarantee the personal security of operating area.
Summary of the invention
The purpose of this utility model provides a kind of train proximity sensing system, utilizes GPS location technology, GSM network and Train Dispatching Command System (TDCS) to judge that train is whether near the technical matters of operating area and early warning with solution.
A kind of train proximity sensing described in the utility model system comprises:
One or more alarm terminal, described alarm terminal are the handhold portable terminal, and this alarm terminal is by treater, respectively bonded assembly GPS registration device, GPRS communicator and phonetic synthesis warning device are formed with treater;
The GSM-INTERNET network, this GSM-INTERNET network realizes that by GPRS link and one or more alarm terminal two way communication is connected.
The early warning computing machine, the early warning computing machine carries out two way communication by GPRS link and network link and one or more alarm terminal;
The Train Dispatching Command System (TDCS) interface computer, this Train Dispatching Command System (TDCS) interface computer links to each other with above-mentioned early warning computing machine by serial communication mode.
Aforesaid a kind of train proximity sensing system, described early warning computing machine comprises GSM-NTERNET and two interfaces of serial communication, described serial communication interface is the one way communication interface, described Train Dispatching Command System (TDCS) interface computer connects the early warning computing machine by the one way communication interface, guarantees physically that serial ports can only be sent out can not receive.
Advantage of the present utility model and good effect are as follows:
1, can judge that train is whether near the operating area and send early warning signal.
2, owing to rely on TDCS system train position raw information, GPS location and GPRS communication, early warning range is big, and accuracy is high and low-cost.
Description of drawings
Fig. 1 is the system architecture scheme drawing of the utility model device.
The specific embodiment
The utility model is based on Train Dispatching Command System (TDCS) (TDCS), GPS location technology and GPRS communication technology structure.The utility model is linked in sequence by one or more alarm terminal, GSM-INTERNET network, an early warning computing machine and a TDCS interface computer and forms.Described alarm terminal is by GPRS Radio Link and GSM-INTERNET network-in-dialing, and described GSM-INTERNET network links to each other with an early warning computing machine, and described early warning computing machine links to each other with a TDCS interface computer by serial communication mode.Described early warning computing machine comprises GSM-NTERNET and two interfaces of serial communication, and described serial communication interface is the one way communication interface.Described TDCS interface computer connects the early warning computing machine by the one way communication interface, guarantees physically that serial ports can only be sent out can not receive.
Because the utility model early warning computing machine has GSM-INTERNET and serial interface, make the early warning computing machine can be used as this device early warning center, connect the intrasystem TDCS interface computer of TDCS by serial interface on the one hand, make full use of TDCS information and carry out early warning calculating; Connect alarm terminal by the GSM-INTERNET interface on the other hand, alarm message is sent to alarm terminal and obtains the alarm terminal location information.Thereby, improve accuracy greatly and reduced cost.
The utility model adopts handheld portable alarm terminal and phonetic synthesis type of alarm, and is not only easy to use, is convenient to safeguard, and avoided erecting equipment on the line, saved cost.
Alarm terminal described in the utility model adopts GPS location and GPRS signalling methods, has not only solved the operation orientation problem accurately, and the alarm terminal range of use is increased greatly, has enlarged early warning range, thereby has also further reduced cost.
Below in conjunction with drawings and Examples the utility model is further specified.By shown in Figure 1, the utility model device comprises alarm terminal 1, and GSM-INTERNET network 7 makes alarm terminal and early warning computing machine 9 to carry out two way communication by GPRS link 6 and network link 8.TDCS interface computer 11 is connected with early warning computing machine 9 by unidirectional serial communication mode 10, be that the TDCS interface computer can only send information, any information and the connection of discord early warning computing machine generation network can not be received, the network information security of TDCS interface computer can be effectively guaranteed.Alarm terminal 1 constitutes core by treater 3, connects GPS registration device 4, GPRS communicator 5 and phonetic synthesis warning device 2 respectively, and wherein GPRS communicator 5 is connected with GSM-INTERNET network 7 by GPRS link 6.
The utility model device produces alarm messages by early warning computing machine 9, after being sent to alarm terminal 1 and being handled by treater 3 by GSM-INTERNET network 7, finishes warning by phonetic synthesis warning device 2 with voice mode.
