Locomotive platform and communication method with functions of tunnel reconnection and train end communication

Abstract

The invention relates to a locomotive platform with tunnel reconnection and train tail communication functions and a communication method. The locomotive platform comprises a power source unit, a channel machine A, a channel machine B, a control panel, a duplexer A, a duplexer B, an electric bridge and a 450M wire, wherein the 13.8V output end of the power source unit is connected with the channel machine A, the channel machine B and the control panel; the control panel is connected with the channel machine A and the channel machine B through communication lines; the channel machine A and the high end of the duplexer A are connected through a radio frequency line; the channel machine B and the coupling end of the duplexer B are connected through a radio frequency line; the low end of the duplexer A and the low end of the duplexer B are connected through a radio frequency line; the coupling end of the duplexer A and the high end of the duplexer B are connected with the input end of the electric bridge; and the output end of the electric bridge is connected with the 450M wire. The locomotive platform and the communication method have the advantages that communication in tunnels is achieved, existing equipment can be replaced conveniently during subsequent upgrading and rebuilding, the cost is not increased much compared with that of the existing equipment, and not only demands of users are met, but also the equipment input cost is controlled for the users.

Description

technical field [0001] The invention relates to a locomotive station for electronic communication, in particular to a locomotive station with functions of tunnel reconnection and train end communication and a communication method. Background technique [0002] The traditional locomotive station itself only has the function of reconnection on the plain. When the locomotive travels into the tunnel and needs to communicate with the host, affected by the signal in the tunnel, the effect of reconnection call and end-of-row communication is poor, the communication is unstable, and communication often occurs Interruption, or even failure to communicate, greatly affects the normal communication requirements of locomotives. In order to solve the problem of low reliability of reconnection call and end-of-row communication in the tunnel, a repeater station is set up in the weak field area of ​​the tunnel to improve the field strength coverage in the tunnel. When the locomotive station ...

Problems solved by technology

[0003] In order to solve the problems of low reliability of reconnection calls and tail-end communication in the tunnel, the present invention provides a locomotive station and a communication method with the functions of tunnel reconnection and tail-of-row communication. A new tunnel reconnection method is used in the tunnel. The mechanism of "tunnel reconnection" can not only ensure the reliability of communication, but also ensure the function of end-of-line communication. , channel machine A, channel machine B, control board, duplexer A, duplexer B, electric bridge and 450M antenna, the 13.8V output end of the power supply unit is respectively connected to channel machine A, channel machine B, and control board, and the control board passes through The communication lines are respectively connected to channel machine A and channel machine B, channel machine A and duplexer A high-end, channel machine B and duplexer B coupling end, duplexer A low-end and duplexer B low-end use radio frequency lines respectively Connection, the coupling end of duplexer A and the high end of duplexer B are respectively connected to the input end of the bridge, and the output end of the bridge is connected to the 450M antenna
