Information such as type, license number, while realizing detecting real-time function, to any time be added or running train after reconnection train organize into groups into
Row Auto-matching, number.
Specifically, the control strategy of matching module counterweight connection T unit 1 is as follows:
Equipment init state is " not organizing into groups " state, and not organizing into groups state train with cycle T 1 is interval by this vehicle packet
It is sent in binding group network again；
The locomotive of " not organizing into groups " state extracts several information in the packet (such as after receiving the information that his vehicle is sent
Vehicle, the unique identification informations such as license number) it is recorded as " previous stage " train information, meanwhile, to binding networking again after the T2 time
This vehicle information is sent in network.If this sends successfully, which is changed to " marshalling " state, if this send successfully it
Before, the data packet of other reconnection trains is received, then extracts the information in this data packet, is denoted as " previous stage " train information, meanwhile,
Using sending this vehicle information into binding group network again after the T2 time.If being received again by data packet, this operation is repeated, until
It sends successfully, until changing this car state,.
The train of " marshalling " state extracts in the packet after the packet for receiving first " non-previous stage " train
Information be recorded as " non-previous stage " train information.Information is latched after " non-previous stage " train information record, it is subsequent no longer to remember
Record other train informations.
After receiving " previous stage " train information packet, setting is ready for sending labeled as true, warp the train of " marshalling " state
This vehicle packet is sent into binding group network again after spending the T3 time.Label will be sent after sending successfully is changed to vacation.
The train of " marshalling " state does not receive his any vehicle packet within the T1 time, and will change this car state is " not
Marshalling " state, removes " non-previous stage " and " previous stage " train information.
The train of " marshalling " state is recorded when receiving " non-previous stage " train information packet each time, is recorded " before non-
After the train of " marshalling " state is successfully transmitted this vehicle packet, this " is received secondary for level-one " train information packet " receive number "
Number " clear 0；Marshaling real-time monitoring sheet " receive number " shows that this vehicle is not joining again if being somebody's turn to do " receive number " is greater than 1
In marshalling, need to change this car state is " not organizing into groups " state, removes " non-previous stage " and " previous stage " train information.
The train of " marshalling " state is successfully transmitted before data packet after receiving " previous stage " train data packet, is received
Other train data packets are arrived, then changing this car state is " not organizing into groups " state, removes " non-previous stage " and " previous stage " train
Information.
Wherein, cycle time T1 > T3 > T2, and be generally on-fixed value, it can change at random in specific sections.When
So, T1, T2 and T3 are that fixed value is also feasible.
In addition, the control strategy of matching module is not limited in above content, specifically also grouped columns can be joined again according to practical
The case where vehicle and carry out corresponding modification, and the process data for supporting " fixed cycle+life signal " of collision detection also can be used
Mode is communicated.
The present invention also provides a kind of reconnection train groups, more trains including interconnection and logical for realizing each train
The reconnection communication system of letter, wherein the reconnection communication system is identical as above content, and details are not described herein again.
The foregoing description of the disclosed embodiments enables those skilled in the art to implement or use the present invention.
Various modifications to these embodiments will be readily apparent to those skilled in the art, as defined herein
General Principle can be realized in other embodiments without departing from the spirit or scope of the present invention.Therefore, of the invention
It is not intended to be limited to the embodiments shown herein, and is to fit to and the principles and novel features disclosed herein phase one
The widest scope of cause.
