Abstract
The invention discloses an interactive communication method based on state transmission data, which belongs to the technical field of secure communication and comprises the following steps: adding a BTM frame transceiving interface in an RSSP-I communication protocol; BTM session timing control is realized on the BTM frame transceiving interface, so that the RSSP-I communication protocol supports the transceiving of the BTM frame data. In the process of data transmission of the RSSP-I communication protocol, a BTM frame data transceiving interface is added in the RSSP-I communication protocol, and a BTM frame data session control time sequence is added on the basis of RSD frame data transmission, so that the RSSP-I communication protocol supports both RSD frame data transmission and BTM frame data transceiving.
Description
Technical field
The present invention relates to safety communication technology field, more particularly to a kind of interactive communication side based on state transfer data
Method.
Background technology
Safety-relevant communication of the RSSP-I secure communication protocols suitable for closed Transmission system, to ensure closing
The security of data interaction under formula Transmission system environment, it is ensured that the security of data transfer between safety-related product.At present,
RSSP-I secure communication protocols only support the transmission of RSD frame data, can not send the transmission of other type frame data, use range
It is greatly limited.
The content of the invention
It is an object of the invention to provide a kind of interactive communication method based on state transfer data, is pacified with abundant RSSP-I
The frame data type that full communication agreement is supported.
To realize object above, the technical solution adopted by the present invention is：A kind of interaction based on state transfer data is provided
Communication means, comprise the following steps：
Increase BTM frame transceiver interfaces in RSSP-I communication protocols；
BTM session SECO is realized on BTM frame transceiver interfaces, so that RSSP-I communication protocols support BTM frame data
Transmitting-receiving.
Wherein, the BTM sessions SECO is increased on the basis of the transmitting-receiving of RSD frame data.
Wherein, the type of message of BTM frames includes SBT, EBT, ABT, BTC and BTD.
Wherein, the BTM sessions SECO, is specifically included：
Start session start condition, whether just service end receives client and send SBT frame formats data and check crc field
Really；
If incorrect, service end continues waiting for receiving SBT frame format data；
If correct, service end initialization communication port, and to visitor after carrying out timing corrections request and being replied with timing corrections
The ABT frame data that family end is sent, complete to initialize and start BTM frame message transmitting procedures.
Wherein, BTM frame messages transmitting procedure, is specifically included：
Service end receives the BTC frame data request that client is sent, and is answered in the request of progress timing corrections and timing corrections
After multiple, the BTC frame data that client is sent are received；
Service end sends the request of ABT frame data to client, so that client carries out data transmission downloading；
Service end sends data cached retransmit to client and asked, so that client enters the data cached transmission stage and connect
Sent by service end data cached.
Compared with prior art, there is following technique effect in the present invention：The present invention carries out data in RSSP-I communication protocols
During transmission, increase BTM frame data transceiver interfaces in RSSP-I communication protocols, and on the basis of the transmission of RSD frame data
Increase BTM frame data session control sequential so that RSSP-I communication protocols are also supported while supporting RSD frame data to send
The transmitting-receiving of BTM frame data.
Brief description of the drawings
Below in conjunction with the accompanying drawings, the embodiment of the present invention is described in detail：
Fig. 1 is a kind of schematic flow sheet of the interactive communication method based on state transfer data in the present invention；
Fig. 2 is the control flow schematic diagram of BTM sessions SECO in the present invention.
Embodiment
In order to illustrate further the feature of the present invention, please refer to the following detailed descriptions related to the present invention and accompanying drawing.Institute
Accompanying drawing is only for reference and purposes of discussion, is not used for being any limitation as protection scope of the present invention.
As shown in figure 1, present embodiment discloses a kind of interactive communication method based on state transfer data, including following step
Rapid S1 to S2：
S1, increase BTM frame transceiver interfaces in RSSP-I communication protocols；
S2, BTM session SECO is realized on BTM frame transceiver interfaces, so that RSSP-I communication protocols support BTM frame numbers
According to transmitting-receiving.
It should be noted that the type of message of BTM frames includes SBT, EBT, ABT, BTC and BTD, its form such as table 1 below：
Table 1
Further, it is to increase the BTM sessions SECO on the basis of the transmitting-receiving of RSD frame data in the present embodiment.Cause
This, the RSSP-I communication protocols in the present embodiment also support the transmitting-receiving of BTM frame data while supporting RSD frame data to receive and dispatch.
Further, as shown in Fig. 2 BTM session SECO, is specifically included：
Start session start condition, service end receives the SBT frame formats data that client is sent and whether checks crc field
Correctly；
If incorrect, service end continues waiting for receiving SBT frame format data；
If correct, service end initializes communication port to send the request of ABT frame data to client, and is carrying out sequential school
The ABT frame data that positive request and timing corrections are sent after replying to client；
Service end receives the BTC frame data request that client is sent, and is answered in the request of progress timing corrections and timing corrections
After multiple, the BTC frame data that client is sent are received；
Service end sends the request of ABT frame data to client, so that client carries out data transmission downloading；
Service end sends data cached retransmit to client and asked, so that client enters the data cached transmission stage and connect
Sent by service end data cached.
It should be noted that the RSSP-I communication protocols in the present embodiment only provide BTM frame data transceiver interfaces, BTM meetings
Words logic-controlled sequential is realized by upper layer application.
The foregoing is only presently preferred embodiments of the present invention, be not intended to limit the invention, it is all the present invention spirit and
Within principle, any modification, equivalent substitution and improvements made etc., it should be included in the scope of the protection.
