The format of a packet for sending information to the surface over the difference between the table below.
The table above is the display that what data are included in the packet to traverse the ground and onboard. You can create a structure that on the basis of this table, with the same structure, the implementation of the program of the actual processes in the program.
(2) The connection between the ground unit inside the machine room DT-8 protocol
It is the content of DT-8 protocol for communication with devices inside the machine room of the second protocol is written in TWC ground equipment. DT-8 is a protocol created by Alstom in terms Data Train8.
It is a protocol used to exchange data with (SCU / ATO / next station, etc.) between the ground equipment, the protocol is referred to as DT-8 protocol. The configuration of the part, DT-8 protocol is as shown below but are divided into 5 parts larger as shown in the figure above.
● Header
Unlike other protocols, rather than using one of the header 1, DT-8 protocol, has the feature that uses a different header depending on the situation. It is possible to see the header of DT-8 in the table below.
As shown in the figure above, the DT-8, the side that is issued an instruction using the header to have a header of all five, corresponding according to each situation, to respond to use this header I make a response Te.
● Buffer address
It is part of most complicated to calculate the address of this buffer in the DT-8 protocol.
There is a table that shows the structure below.
DT-8 protocol itself, which operates the station number 64, the S / W buffer virtual four respective communication ports each, it is possible to manipulate the buffer up to 256 theoretical it has a structure. On the ground TWC system, by using this structure, as shown in the above figure, the lower 2 bits is to be able to specify a buffer number 4, the station number up to 64, the upper 6 bits to use separate was to be able to configure the buffer independent.
Station number that is used for the upper 6 bits is as shown in the following table.
The body part of the DT-8, is a partial data to be transmitted is entered. Instead of sending all the data to be transmitted, the characteristics of DT-8 protocol is a protocol that has a function of transmitting to choose only a portion of the change of the data to be transmitted occurs. Such a structure is a protocol used in a method to reduce the amount of traffic the instantaneous when the number of received data is large, thereby maintaining the integrity of the data between the transmission and reception. Of course, there is also a method to come at once received the key frame by requesting a complete data.
Body part of the DT-8 is on the idea that the index of the data change occurs as shown in the illustration above, it is transmitted together in pairs as shown above the data changes occur. In the above figure, "index" is the value of the position of the data change has occurred in the transmission data buffer, the data refers to data for that location.
● CRC & DLE Run
Using the method of calculating CRC-16 standard, CRC, are arranged in the order of upper and lower bytes.
Range of DLE processing and range of the CRC calculation is as follows.
● Terminator
This means that inspects the packet reception ends to detect the terminator receiving packets, or a packet of normal, it is confirmed that it is out-of-order packets, and terminates the reception of the packet. DT-8's in the following table to use the termination character of the two.
If it is not the case there is data to be transmitted still in the buffer as shown in the table terminator the more data that had remained more, so that can be used to suit each case, as this . Reason to use it to separate into two terminator, the DT-8 protocol, can not be the length of the protocol message exceeds the maximum 128byte, but if the volume of messages exceeds 128byte, by dividing it into multiple messages it indicates that the need to send the data transfer is not completed using the terminator 0xA8 this time, that the transmission of the message is completed using as the terminator 0xA9 after sending a packet of the last message announce.
● DLE
DLE is that DLE to or transmitted divided by 2 bytes bytes that do not overlap with the control code data constitute a frame of a packet are combined into one obtained by dividing the both bytes and restore the original values I to be processed.
In this protocol, if there is a value in 0xA0~0xAF the CRC value and data, the data is 0xA0 (eg, data 0xA7à0xA0,0x07) during reception and transmission by converting the 0xA0 + 0x0n this value Upon reception, it reads the next byte, it is restored to its original value by more that value 0xA0. (Example: data 0xA0,0x03à0xA3)
