A Method for Correction Ranging of Train Based on RSSI

Abstract:

In the railway operation, it's significant to obtain the distances between trains. A method based on RSSI for ranging and correction is proposed in this paper. The devices include a number of base stations installed along railways. The front train would send an active signal to the nearby base station N, when it transmits power signal to the following one. The following train also gives an active signal to its nearest base station 1 which would be enabled to gain signal from station N. The error of per meter of every section would be calculated by the known distance between base stations. The distances between trains could be corrected by the error and the loss of RSSI signal. The experiment result shows that this method is effective.
