s301, receiving a data packet sent by the security check machine.

The data packet may be an image packet, an original data packet, a handshake request packet, etc., sent by the security check machine. In an alternative embodiment of the invention, after the connection between the graph judging platform and the security inspection machine is established, the security inspection machine and the graph judging platform handshake first, the graph judging platform can receive a handshake request message sent by the security inspection machine, the graph judging platform can generate a handshake response message based on a communication interface protocol, the packet header of the handshake response message comprises a message field number of a handshake response service, and the packet body of the handshake response message comprises a version number of the graph judging platform.

As shown in table 1 in the first embodiment, table 1 is a packet header defined in a communication interface protocol, table 2 defines a data service corresponding to a message field number, for example, a handshake request message service field number is 0x00010003, and table 3 defines security check machine information included in a packet body of the handshake request message. The security check machine may generate a handshake request message based on tables 1,2 and 3 and send the handshake request message to the graph judging platform. The graph judging platform analyzes the handshake request message based on the tables 1,2 and 3 to obtain information such as a manufacturer, a model, a version number, a graph judging mode, a device serial number and the like of the security inspection machine.

Meanwhile, the image judging platform can generate a handshake response message, the message field number in the packet header of the handshake response message is the field number (0 x 00020003) of the handshake response message in table 2, the packet body comprises the version number of the image judging platform, after the security inspection machine receives the data packet of the handshake response message, the packet header is analyzed to determine that the data packet is the handshake response data packet, the security inspection machine and the image judging platform handshake successfully, and the security inspection machine can upload images to the image judging platform.

Step 302, parsing the data packet to extract a message field number from a header of the data packet.

Specifically, in the first embodiment, the packet header structure shown in table 1 includes a message field number, and as shown in table 2, is a data service corresponding to the message field number, and the graph judging platform first analyzes the packet header of the received data packet to obtain the message field number.

Step 303, when the message field number is a field number set by an image uploading service in a preset communication interface protocol, extracting a sub-image and a first description value from the packet body.

Specifically, after extracting the message field number from the packet header, the graph judging platform can determine that the data packet is a data packet of the image uploading service if the message field number is a field number set by the image uploading service in a preset communication interface protocol, specifically, can search the message field number of the image uploading service in the communication interface protocol, as shown in a chart 2, and can extract the sub-image and the first description value from the packet body of the data packet if the message field number in the packet header of the data packet is 0x00010004, which indicates that the data packet is the data packet of the sub-image uploading.
