Locomotive signal system based on wireless sensor network and data source

Abstract

The invention relates to a network database. The network database includes tracking train interval time data items. A locomotive signal system comprises an annunciator which is used for acquiring spatio-temporal data by a data source on the ground and simultaneously used as a sensor node and a management object of a wireless sensor network to cooperate with a networking annunciator in a network coverage area to monitor the annunciator and generate a locomotive signal of the annunciator and a data source which is used for monitoring the event that the train arrives at the geographic position ofthe data source, generating spatio-temporal data and outputting the spatio-temporal data to the annunciator on the train; a database comprises geographic position element identification code data items used for describing attributes of geographic positions where train operation lines are located, length data items used for describing attributes of the train operation lines between the geographicpositions where the train operation lines are located, and length data items used for describing attributes of the train operation lines. A train working diagram includes tracking train interval timedata items. The system is advantaged in that the train can autonomously and credibly obtain the position and speed information of an adjacent train to control autonomy and driving safety.

Description

technical field [0001] The invention belongs to the field of railway transportation applications, relates to geographic information systems, computer science and technology, physics and railway science and technology, in particular to a locomotive signal system based on wireless sensor networks and data sources. Background technique [0002] A locomotive signal is a signal in the cab indicating the operating conditions ahead of the train. On the premise that the ground signal is the main signal, the locomotive signal is an auxiliary signal, which can automatically reflect the display status and operating conditions of the ground signal in front of the train, indicate the train running, and combine with the train automatic parking device to ensure the safety of the train safe operation. At present, the signal has not yet been subject, and it is difficult to guarantee the safety of the train controlled by the "transporter". The control effect of the "carrier" depends on the ...

Problems solved by technology

[0004] In the transportation organization under the condition of large-scale network operation of lines, the impact of emergencies will spread along the two dimensions of time space and network space. The formulation of traffic rules is more complicated, and it is an urgent problem to be solved by the new generation of train operation control system to solve the impact of emergencies and the loss of road network capacity
