Problems solved by technology

However, there is usually a situation at present: the protocols implemented by each equipment manufacturer may be different, which leads to the mixed application of different protocols in many cases due to actual needs. For example, the 104 protocol is used for general calls. Burst upload and other operations, but for the fixed value part, the class 103 protocol is used (the class 103 protocol is not a pure 103 protocol, but a combined frame of 103 and 104 protocols), which blurs the distinction between various protocols. The framing method is also more flexible and changeable
Therefore, there will be difficulties in the communication of devices such as gateways and other devices used to implement a specific protocol
[0003] The current protocol conversion method is usually designed for two specific protocols, such as the conversion between the IEC104 protocol and the DL / T 645 protocol, or the conversion between the IEC 60870-5-104 and the GOOSE protocol. This design can only deal with two In the case of a mixed application of multiple protocols, for a mixed application with more protocols, there may still be communication difficulties

Embodiment 1

[0033] This example discloses an adaptive communication method between the multi-scale devices,

[0034] Step 1: Receive the packet issued by the master, resolve the header and packets;

[0035] Step 2: Establish a status packet database, and check the news head and packets according to the database, and determine the statutes corresponding to the message;

[0036] Step 3: Select the corresponding packet format based on the regulatory classes to perform a group frame reply.

[0037] Packet head (APCI) typically includes information such as starting character, length, control domain, link address domain, link user data length, frame check, and end character.

[0038] The newspaper (ASDU) typically includes type identification, variable structure defining words, transmission reasons, application service data unit common addresses, information body elements, and the like.

[0039] Precursted the statutes of the protocol and the mapping relationship of the norms and packets, and the c...

Embodiment 2

[0051] The object of this embodiment is to provide a computing device.

[0052] A computing device, applied to a sub-station, including a memory, processor, and a computer program stored on the memory and can run on the processor, the processor performs the following steps, including:

[0053] Step 1: Receive the packet issued by the master, resolve the header and packets;

[0054] Step 2: Establish a status packet database, and check the news head and packets according to the database, and determine the statutes corresponding to the message;

[0055] Step 3: Select the corresponding packet format based on the regulatory classes to perform a group frame reply.

Abstract

The invention discloses a self-adaptive communication method and device for multi-protocol equipment. The method comprises the following steps: receiving a message sent by a master station, analyzing and obtaining a message header and a message body; establishing a protocol message The database checks the message header and the message body sequentially according to the database, and judges the protocol class corresponding to the message; according to the protocol class, selects the corresponding message format to perform framing reply. The invention can realize self-adaptive communication between devices of different protocol types.

Description

Technical field [0001] The invention belongs to the field of intelligent power communication, and more particularly to an adaptive communication method and apparatus for a multi-scale device. Background technique [0002] Traditional telephoto communication regions generally have standard regulations such as IEC60870-5-101, IEC60870-5-102, IEC60870-5-103, IEC60870-5-104, which provide norms for all-purpose equipment to achieve interoperability And basis. Suppose the A manufacturer main station implementation 104 regulations, the B manufacturer sub-station also implements the 104 regulation, then the master station and sub-station can communicate. However, there is currently a situation in which the stations implemented by each device manufacturer may not be the same, which has led to a lot of cases, there is a mixed application of different regions, such as the 104 specification, and time, Sudden operation, etc., and for the set of references, the class 103 status (class 103 spec...
