After data to be transmitted equipment is by certification, it is also necessary to send registration letter according to the pact orientation server of communication protocol
Breath.Information relevant to local area network, such as IP address, subnet mask, the default gateway of equipment etc. are generally comprised in registration information,
It further include information of equipment itself, such as a certain parameter of device name, equipment etc..Note of the server to data equipment to be transmitted
Volume information is checked, if registration information is errorless, the success of data to be transmitted facility registration.Registration can be considered as server and recognize
On the basis of card, the specifying information of data to be transmitted equipment is obtained, it is final to confirm data to be transmitted equipment as LAN node
Qualification.After succeeding in registration, data to be transmitted equipment could normally be connected into local area network, become a node in local area network, can
To be communicated according to communication protocol with server or by server with other equipment, transmit data.
The result of certification and registration can be fed back to data to be transmitted equipment by server.It has not yet registered successfully to be transmitted
Data equipment can only request to be authenticated or registered to server, and server is not responding to any other data of the equipment and passes
Defeated request, the equipment can not carry out normal data transmission and communication with server.It can be effectively prevented in this way and do not have networking
The equipment of qualification is connected into local area network, fully ensures that the stability and safety of local area network operation.

Formula or data length read the data in message header, can obtain all information of message header.One typical message header, packet
Include identification information, message attributes information, message header check information and message body check information.Identification information is to disappear for identification
The mark for ceasing head, is normally at the initial position of message header.Identification information generally uses the character string of certain length, above-mentioned character
String, without other semantemes in communication protocol, is not easy and other data obfuscations in message in this way other than as identification information.
Message attributes information generally includes message length information and message type information.Message length information is for recording
(if the data length that communication protocol defines message header is constant, the data length of message header is not necessarily to the data length of message body
Re-record) or message header and message body data length summation.Message type information is for recording according to preset point
The type for the message that class method provides.By identification information and message length information, message body data can be accurately identified.It determines
Message type information is convenient for the subsequent processing to data in message.
Message header check information and message body check information generally use check code, such as CRC (Cyclic
Redundancy Check, cyclic redundancy check) code.Message header check information is used to verify the data of message header, and
Message body check information is for verifying the data of message body.
S103, after receiving message header, according to message header check information verification message head；If message header verification is errorless, then
According to message body check information verification message body；If message header verification is wrong, do not disappear further according to the verification of message body check information
Cease body.
The encapsulating structure of message, usual message header is before message body.Message header is generally first sent when sending message to send out again
Send message body.Corresponding, it is typically also first to receive the message that the node that data are received in local area network, which receives a piece of news,
Message header.After identifying message header by identification information, school is carried out according to data of the message header check information to message header first
It tests.The data check of a kind of situation, message header is errorless, then then carries out further according to data of the message body check information to message body
Verification.If the data check of message header is errorless and the data check of message body is also errorless, normal to handle message body data；And
If the data check of message header is errorless but the data check of message body is wrong, according to the rule process of agreement.Another feelings
The data check of condition, message header is wrong, then does not verify further according to data of the message body check information to message body, directly press
Rule process as agreed.Since the integrated environment of workshop is complicated, disturbing factor is extremely more, is difficult accurate judgement data transmission procedure
In which specific data there is mistake, the node that usually all agreement receives data will verify wrong message and all abandon, notice
The node for sending data retransmits message.
The step S101 of the present embodiment, data to be transmitted equipment, which needs to verify twice by certification and registration, can just be connected into office
Domain net carries out data transmission, and the equipment for not having permission is strictly prevented to be connected into local area network.Step S102 and S103 can be sent out in time
