Trackside device, track star chain system and train operation control system

A track star chain system, characterized by comprising a plurality of trackside devices, wherein each of the plurality of trackside devices comprises:

• a sensor circuit configured to collect detection information at a side of a track;
• a processing circuit configured to process the detection information to obtain a processing result, wherein the processing result comprises at least one of the following:
• a track section having been cleared, the track section having been occupied, an obstacle detection result and an obstacle recognition result;
• a trackside resource control circuit configured to drive and control a trackside resource when a trackside resource request is received from a target train and the trackside resource is in a released state, wherein the trackside resource control circuit is further configured to monitor a state of the trackside resource;
• and
• a communication circuit configured to communicatively connect with a ground center and the target train and send the processing result and/or the state of the trackside resource to the ground center and/or the target train, communicatively connect with another trackside device through ad hoc networking technology and/or multi-hop networking technology;
• and
• a positioning circuit configured to position the target train and correct position information obtained by the target train through its own positioning system to obtain position information of the target train, wherein the positioning circuit is configured to:
• obtain a position deviation between position information obtained by the trackside device from positioning the target train and the position information obtained by the target train through its own positioning system;
• determine the position information obtained by the target train through its own positioning system as the position information of the target train when the position deviation does not exceed a first threshold;
• and determine an average value of the position information obtained by the trackside device from positioning the target train and the position information obtained by the target train through its own positioning system as the position information of the target train when the position deviation exceeds the first threshold but does not exceed a second threshold.

A train operation control system, characterized by comprising:

• a target train;
• a ground center;
• and
• at least one trackside device, wherein the trackside device is communicatively connected with the ground center and the target train and comprises:
• a sensor circuit configured to collect detection information at a side of a track;
• a processing circuit configured to process the detection information to obtain a processing result, wherein the processing result comprises at least one of the following:
• a track section having been cleared, the track section having been occupied, an obstacle detection result and an obstacle recognition result;
• a trackside resource control circuit configured to drive and control a trackside resource when a trackside resource request is received from a target train and the trackside resource is in a released state, wherein the trackside resource control circuit is further configured to monitor a state of the trackside resource;
• and
• a communication circuit configured to communicatively connect with a ground center and the target train and send the processing result and/or the state of the trackside resource to the ground center and/or the target train, communicatively connect with another trackside device through ad hoc networking technology and/or multi-hop networking technology;
• and
• a positioning circuit configured to position the target train and correct position information obtained by the target train through its own positioning system to obtain position information of the target train, wherein the positioning circuit is configured to:
• obtain a position deviation between position information obtained by the trackside device from positioning the target train and the position information obtained by the target train through its own positioning system;
• determine the position information obtained by the target train through its own positioning system as the position information of the target train when the position deviation does not exceed a first threshold;
• and determine an average value of the position information obtained by the trackside device from positioning the target train and the position information obtained by the target train through its own positioning system as the position information of the target train when the position deviation exceeds the first threshold but does not exceed a second threshold.
