Embodiment 1

[0054] Such as image 3 As shown, the known parameters include: signal propagation speed V, the distance D1 from one remote machine 1 to the near-end machine, and the distance D2 from the other remote machine 2 to the near-end machine; The distance S, the time a when the train sends information, the time a+t1 when the information sent by the train via the remote machine 1 arrives at the near-end machine, the time a+t2 when the information sent by the train via the remote machine 2 arrives at the near-end machine, two The location information of a remote computer;

[0055] According to the signal propagation speed V, the distance D1 from one remote machine 1 to the near-end machine, and the distance D2 from the other remote machine 2 to the near-end machine, calculate the time T1 for the information sent by the remote machine 1 to reach the near-end machine =D1 / V and the time T2=D2 / V for the information sent by the far-end machine 2 to arrive at the near-end machine;

Embodiment 2

[0071] Such as image 3 As shown, the known parameters include: the change M of the signal strength attenuation degree with the distance, the distance D1 from the far-end machine 1 to the near-end machine, and the distance D2 from the other far-end machine 2 to the near-end machine; The distance S between the remote computers, the moment a when the train sends out information, and the location information of the two remote computers;

[0072] According to the change M of the attenuation degree of the signal strength with the distance, the distance D1 from one remote machine 1 to the near-end machine, and the distance D2 from the other remote machine 2 to the near-end machine, it is calculated that the information sent by the far-end machine 1 reaches the near-end machine. The signal strength loss m1=M(D1) when the terminal machine and the information sent by the far-end machine 2 arrive at the signal strength loss m2=M(D2) of the near-end machine;

[0073] Then calculate the ...

Abstract

The invention provides a railway locating system utilizing a repeater. The railway locating system comprises the repeater, the repeater comprises a near end machine and multiple far end machines, andthe far end machines are arranged on a track of a train; the near end machine is internally provided with a first optical port, a data processing center and a computing module, each far end machine isinternally provided with a second optical port, an antenna, a data processor and a locating chip, the data processing center is connected with the computing module and the first optical port separately, the first optical port is connected to the second optical port, and the data processor is connected with the second optical port, the locating chip and the antenna separately. The invention further provides a railway locating method utilizing the repeater. Position information of the far end machines and train information forwarded through the far end machines locate the train.

Description

technical field [0001] The invention relates to a positioning system, in particular to a railway positioning system using a repeater and a positioning method thereof. Background technique [0002] There are two methods commonly used in today's train positioning: the train has its own positioning signal receiver, or fixed monitoring points are set up along the railway, and the positioning is calculated by receiving signals from the monitoring points. The former cannot guarantee that the train can receive positioning signals at any time due to location and terrain reasons (tunnels, etc.), and real-time positioning cannot be achieved; the latter requires a large number of monitoring points and high costs due to the large scope of the railway. Contents of the invention [0003] One of the technical problems to be solved by the present invention is to provide a railway positioning system using a repeater, which uses the position information of the remote machine and the train i...
