The method of the railway transportation platform for marshalling includes the status number of the mobile peripheral system transmission train
According to the center system；
The method that the status data of the mobile peripheral system transmission train gives the center system are as follows: the mobile peripheral system
Processor be connected with flash memory, store the transmitting mould for the status data of train being passed to the center system in a flash memory
Block, the center system are connect with cloud platform, and the mobile peripheral system is connect with cloud platform, with mobile peripheral system described in this
Transfer module is run the status data of train is passed to the center system via cloud platform；

The center system transmitting information transmitting instruction, mobile peripheral system is by information transmitting instruction the communication information point
It is transmitted for several message segments towards center system, a corresponding sound will be transmitted when center system one obtains a message segment
Answer message to the mobile peripheral system；
When mobile peripheral system does not obtain the corresponding response message of more than one message segment, by the response message of acquisition
The corresponding message segment of response message that does not obtain of time delay identification execute phase either with or without drain message, and by drain message situation
It should handle.
It is described to assert that the corresponding message segment of response message not obtained includes: either with or without the method for drain message
By the time delay of the response message of acquisition, the time delay section of the response message not obtained is obtained, if exceed described
Prolong section and do not obtain the corresponding message segment of the response message, it is assumed that the message segment has drain message.
Time delay fluctuation can be obtained by the time delay of the acquired response message of whole before the response message not obtained
Upper limit value then combines this time delay then by the time delay of the acquired response message adjoined before the response message not obtained
The upper limit value of fluctuation is not just received the upper limit value of the time delay of response message, if exceeding the upper limit value of the time delay, it is assumed that
The corresponding message segment of the response message has drain message.
For example, the number of message segment of this transmitting is four pairs, respectively message segment one, message segment two, message segment three, report
Literary Duan Si, message segment five, message segment six, message segment seven and message segment eight obtain the response message of message segment one, message segment two
Response message, the response message of message segment three, the response message of message segment four and message segment five response message with message segment seven
Response message and message segment eight response message, the response message of message segment six do not receive, the response message of message segment one,
The response message of message segment two, the response message of message segment three, the response message of message segment four and message segment five response message
Their time delay is respectively: 2 seconds, 1.6 seconds, 2.2 seconds, 1.8 seconds and 2.4 seconds, the response message of message segment one and message segment two
The time delay fluctuation of response message is 0.4 second, and the time delay fluctuation of the response message of the response message and message segment three of message segment two is
0.6 second, the time delay fluctuation of the response message of the response message and message segment four of message segment three was 0.4 second, the response of message segment four
The time delay fluctuation of the response message of message and message segment five is 0.6 second, and the upper limit value of such time delay fluctuation is exactly 0.6 second, therefore
Message segment six was served as with the upper limit value of the time delay fluctuation between message segment five 0.6 second, and the delay upper bound value of message segment six is 2.4 seconds
In addition obtaining within 0.6 second 3 seconds, the time delay lower limit value of message segment six is to subtract within 2.4 seconds to obtain within 0.6 second 1.8 seconds, therefore exceeding 3 seconds
And when not obtaining the response message of message segment six, it is omitted it is assumed that information occurs for message segment six.
When assert that the message segment not obtained has drain message, disposition is executed by drain message amount:
Drain message amount capacity account for the message segment not obtained capacity percentage less than 25% when, can be via
HAMMING algorithm once again passes to the center system after the message segment for having drain message is executed correction；
The percentage of the capacity for the message segment not obtained is accounted for when 25% or more in the capacity of drain message amount, it cannot be via
HAMMING algorithm once again passes to the center system after the message segment for having drain message is executed correction, just the communication
Whole message segments of information are transmitted towards the center system again.
The message segment number transmitted under the period that the estimation that the mobile peripheral system can continue is set now, that is,
The message segment number transmitted now, the message segment number transmitted now are the period by first an equal amount of setting
The number estimation of the message segment of transmitting comes.Transmitting the time delay of five message segments as the period of first setting is 1.68 seconds, separately
The outer normal time delay mean value of five message segments is 0.32 second, therefore time delay is longer in the period of first setting, cloud platform resistance
Plug situation is more serious, then the period set now must reduce the message segment number of transmitting, the period set now is just estimated to pass
Pass two teams' message segment；If the time delay of five message segments of period of first setting is 1.4 seconds, therefore the period of first setting
Time delay it is shorter, which just transmits three pairs of message segments.
The number that the mobile peripheral system is used to transmit message segment now is normally passed in the mobile peripheral system always
In the section of the number of defeated message segment.
Each information transmitting instruction is set with a weighted value, which is used to specify communication information importance
, weighted value is bigger, and the communication information is more important；Successively transmitting a pair of of weighted value in the center system sequence has different information
When transmitting instruction, mobile peripheral system relies on weighted value, first transmits the bigger communication information of weighted value, then transmits weighted value
The smaller communication information.
Drain message amount capacity account for the message segment not obtained capacity percentage less than 25% when, can be via
HAMMING algorithm once again passes to the center system after the message segment for having drain message is executed correction；It is just avoided that again
The time for all sending waste accelerates information transmitting；It can be by the acquired sound of whole before the response message not obtained
The time delay for answering message obtains the upper limit value of time delay fluctuation, then by the acquired sound adjoined before the response message not obtained
The time delay of message is answered, the upper limit value of this time delay fluctuation is then combined just not received the upper limit value of the time delay of response message,
If exceeding the upper limit value of the time delay, it is assumed that the corresponding message segment of the response message has drain message, it is thus efficient rapid
Information transmitting as a result, improve information pass speed.
