Detailed Description
In order to make the objects, features and advantages of the present disclosure more apparent and understandable, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present disclosure, and it is apparent that the described embodiments are only a part of the embodiments of the present disclosure, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure.
At present, the communication between the upper computer software and the algorithm software usually adopts an interface calling mode or a TCP/IP protocol mode. The mode of interface calling is adopted, so that the workload of an upper computer development engineer is huge, and when an algorithm library has problems, the troubleshooting is not convenient, and the implementation is not convenient. However, the TCP/IP protocol is not versatile enough to quickly multiplex the communication part between the transmitting end and the receiving end. For example: the protocol portion of the TCP/IP protocol typically includes: a bag head and a bag body; the packet head portion includes: commands, packet data length, command additional information, etc. When the detection object of the command is changed, the additional information of the command needs to be changed, and because the packet header data is generated according to the TCP/IP protocol, if the additional information in the packet header needs to be modified, the additional information is very inconvenient, not easy to modify, high in cost consumption, incapable of better meeting the application requirements of multiple scenes, and poor in universality. Secondly, the packet body of the TCP/IP protocol part can bear a small amount of data, and when the packet body information sent at one time contains a plurality of images or a plurality of feature points, the packet body of the TCP/IP protocol part cannot complete the data bearing of the plurality of images or the plurality of feature points, and cannot well meet the use requirements of various scenes, such as the width and height of the images or the data types and the like. Furthermore, the TCP/IP protocol cannot handle the sticky data packets in the case of long connection, that is, when a plurality of data packets are sent out, the front and back data packets are stuck to each other. Therefore, the inventor proposes a data interaction method, a system, an electronic device and a storage medium, and firstly, a sending end assembles original data according to a preset custom protocol to obtain a protocol data packet. Wherein, the sending end can be upper computer software. The protocol data packet includes: the system comprises a header, an ontology packet and data additional information for describing and defining the ontology packet. The storage format of the data additional information is xml, and when the acquired service requirement information changes, the protocol data packet is adjusted by modifying the data additional information. And, establishing a long connection with at least one receiving end, generating at least one communication link. And transmitting the protocol data packet to a receiving end by using the communication link. The receiving end may then be algorithmic software. The method enables the sending end and the receiving end to carry out flexible communication, and realizes information interaction between the upper computer software and the algorithm software. When the service requirement information or command changes, such as the detection object changes, the method can better adapt to various scenes by modifying the data additional information in the xml format, is more convenient to operate, better realizes the quick multiplexing of a communication part between upper computer software and algorithm software, has higher flexibility, stronger universality and more convenient operation, has less workload of development and maintenance, has larger information of a data body which can be born, and effectively avoids data package sticking.
Referring to fig. 1, a data interaction method provided by the present disclosure includes:
s11: the sending end assembles the original data according to a preset custom protocol to obtain a protocol data packet, wherein the protocol data packet comprises: the system comprises a packet header, an ontology data packet and data additional information for describing and limiting the ontology data packet; the storage format of the data additional information is xml, and when the acquired service requirement information changes, the protocol data packet is adjusted by modifying the data additional information.
Specifically, the sending end can be upper computer software. The service requirement information refers to information of a service to be executed, and can be set according to actual conditions, such as service requirements for visual detection of a keyboard or a screen in an image. When the service requirement information changes, the rapid multiplexing of the communication part between the sending end and the receiving end can be realized by modifying the data additional information in the xml format. For example: when the acquired service requirement information changes, that is, new service requirement information is acquired, assuming that the new service requirement information is used for performing visual detection on a screen and a keyboard of a notebook, detection of the keyboard or screen detection needs to be shielded sometimes in the detection process, that is, shielding of a detection item is involved, the requirements can be completed by modifying data additional information, that is, adding node information < KeyBoardTest > true </KeyBoardTest > < PanelTest > and < PanelTest > false < PanelTest > to the data additional information in an xml format, so that shielding of the detection item is realized, and the multiplexing speed is high.
Unlike existing TCP/IP protocols, the protocol data packets generated by the present disclosure using custom protocols include: a header, data additional information, and an ontology packet. The structure of the protocol data packet is shown in fig. 2.
Because the additional information of the command in the packet header of the existing TCP/IP protocol cannot be extended and modified well, in this embodiment, the packet header of the protocol data packet removes the additional information of the command in the packet header of the existing TCP/IP protocol, and the data additional information in the xml format is added outside the packet header to describe and limit the body data packet, such as the data group information and the data storage path in the body data packet.
Further, the packet header of the protocol data packet of the present disclosure is used for the receiving end to analyze and acquire the additional data information and the body data packet, and the structure of the packet header refers to fig. 3, which includes: a service command (cmd), a data additional information length (data _ sub [0]), and a body packet length (data _ sub [1 ]).

The total number of data packet periods refers to a total number of data packet periods, and the number of data packet periods refers to the number of data packet periods. The size of the header is 64Bytes, Byte represents Byte, 1Byte =8bits, and bit is a measurement unit, meaning bit.
Please refer to fig. 4 for a structure of an ontology packet in the present disclosure. The ontology data package in this disclosure includes at least one sub-package, and the sub-package includes: data delimiters, data description information and data volumes. Wherein the data description information includes: sub-packet data length (data len), sub-packet data type, and optional fields. The sub-packet data types include: main data type (Main data type), Sub data type (Sub data type), Sub packet number (data No). Optional fields include: an image width (image width) and an image height (image height), and when the sub-packet data type is an image, the optional fields are valid fields. 0x00, 0x01 denote hexadecimal numbers. In fig. 4, a byte stream is composed of sub-packets 1 and 2 to form an ontology data packet. The data packet format has high flexibility and high universality.
