specific Embodiment approach

[0049] The core of the present invention is to provide a backup network detection method with a master-slave structure, and a schematic flowchart of a specific implementation is as follows: figure 1 As shown, it is referred to as the specific embodiment one, including:

[0050] S101: Acquire packet data from the buffer of the standby network.

[0051] S102: Traverse the message data according to preset frame format information, and determine whether the message data includes frame message information.

[0052] The frame message information in this step refers to complete frame message information.

[0053] S103: When the message data includes the frame message information, determine that the backup network is normal; when the message data does not include the frame message information, determine that the backup network is faulty.

[0054]Further, the number of complete frame message information can be set to determine whether the backup network is normal. For example, when t...

specific Embodiment approach 3

[0086] On the basis of the specific embodiment 1, a method for considering multiple pieces of message data together is further proposed, and the schematic flowchart is as follows image 3 As shown, the contract period is specific implementation mode three, including:

[0087] S301: Acquire a first amount of packet data from a buffer of a standby network.

[0088] The first number can be selected according to actual needs, but must be an integer greater than one.

[0089] S302: According to the preset frame format information, traverse the first quantity of the message data respectively to obtain quantity information of the message data including the frame message information.

[0090] S303: Determine whether the quantity information exceeds a first threshold.

[0091] S304: When the quantity information exceeds the first threshold, determine that the backup network is normal; when the quantity information does not exceed the first threshold, determine that the backup network...

Embodiment approach

[0099] As a preferred embodiment, the framing module includes:

[0100] a start selection unit, configured to traverse the message data according to the frame format information, and determine whether the message data includes a start byte;

[0101] A to-be-checked determining unit, configured to determine a to-be-checked frame byte according to the start byte when the start byte exists in the message data;

[0102] a format review unit, used to judge whether the format information of the bytes in the frame to be checked conforms to the frame format information;

[0103] A frame determination unit, configured to determine that the message data includes the frame message information when the format information of the bytes in the frame to be checked conforms to the frame format information.

[0104] As a preferred embodiment, the framing module includes:

[0105] A zero frame unit, configured to determine that the frame message information is not included in the message data ...

Abstract

The invention discloses a backup network detection method of a master-slave structure, which obtains message data from a buffer of a backup network; traverses the message data according to preset frame format information, and determines whether the message data is in the message data. Including frame message information; when the message data includes the frame message information, it is determined that the backup network is normal; when the message data does not include the frame message information, it is determined that the backup network is faulty . The invention determines whether the backup network has missing data by detecting whether the backup network includes a complete frame of message information, and realizes the automatic inspection of the status of the backup network. Compared with the prior art, the invention greatly improves the Reduce labor costs and improve production safety. At the same time, the present invention also provides a standby network detection device, device and computer-readable storage medium with the master-slave structure having the above beneficial effects.

Description

technical field [0001] The present invention relates to the field of industrial automation, and in particular, to a method, device, device and computer-readable storage medium for standby network detection with a master-slave structure. Background technique [0002] In the field of industrial automation, data communication between devices is particularly important. In the prior art, serial bus is usually used to realize information communication among devices in the system. There are many safe transmission methods for serial bus. Redundant transmission is a One of the methods is to set the main working network and the backup network, and receive the bus protocol message data sent by the master at the same time. During normal operation, only the main working network will process the received data and send it to other devices. When the working network fails, it can seamlessly switch to the backup network to continue data processing and transmission. [0003] Naturally, how to...
