Detailed Description
The invention is described in detail below with reference to the drawings and examples of the specification:
fig. 1-4 are schematic diagrams illustrating an embodiment of a method for rapidly configuring and networking a station in an open bid evaluation site according to the present invention.
A networking method for rapidly configuring a station of an open bid evaluation site comprises the following steps:
s1, main machine position configuration: the main machine position is generated through two modes of manual configuration and offline automatic change.
S1-1, manual configuration mode:
in the initial non-configuration stage or when needing manual change due to external reasons, selecting a machine position to manually set address information, field codes and marking information of the host position through a local configuration management interface, storing the configured information and the configured time into a local database, and informing the server when the machine is set as the host position;
the server side receives the host bit change request, judges the new host bit setting time, if the new host bit setting time is longer than the old host bit setting time, the host bit information is updated and the host bit information is returned successfully, and then actively informs the old host bit to degrade the old host bit into the slave bit.
The host bit set manually receives a response that the server is successfully set, broadcasts to notify other machine bits, and broadcasts to notify a protocol (a protocol header [0x300525] a data type [0x02] length [0x18] content [ host bit encoding and setting time ] check code [0x52 ]).
The old host position receives the host position setting broadcast, and when the setting time is longer than the host position setting time of the local machine, the host position mark of the local machine position is cleared and the old host position is degraded into a common machine position;
other machine positions receive the host position setting broadcast and store host position information in a local database, see fig. 1.
S1-2, offline automatic change mode:
the invention is provided with an online state management module to monitor the machine position.
Each machine position sends a local health state to the server at intervals (every 60 seconds), and when the server receives a machine position health state request, the machine position information recorded by the server is changed to the database, and the state is changed into an online state; when the server side does not receive the heartbeat data of a certain machine position within the set time (within 200), the machine position is changed into an off-line state.
When the machine position changing the off-line state is the master machine position (namely the server side judges that the master machine position is off-line), the server side automatically searches for the slave machine position of the latest heartbeat and actively informs the slave machine position to upgrade into the master machine position; and the notified slave computer receives the upgrading command to notify the server, and after the server returns success, the server broadcasts to notify other computer positions. Broadcast notification protocol (protocol header [0x300525] data type [0x02] length [0x18] content [ host bit encoding and set time ] check code [0x52 ]).
And the old host position receives the host position setting broadcast, and clears the host position mark of the local host position and degrades the old host position into a common host position when the setting time is longer than the setting time of the local host position.
Other machine positions receive the host position setting broadcast and store host position information in a local database, see fig. 2.
S2, discovering the machine position of the local area network; the unconfigured machine bit broadcasts UDP packets once every a period of time (10 seconds) and broadcasts a notification protocol (protocol header [0x300525] data type [0x01] length [0x18] content [ machine bit coding ] check code [0x52 ]).
When the host position receives the broadcast data, adding the received local area network machine position information and the discovery time into a local discovered machine position list, and informing a server of the currently discovered machine position list; if the broadcast is not received for more than the set time (35 seconds), the found station information is deleted, see fig. 3.
S3, configuring from the machine position; the slave machine position is generated by two modes of server side configuration and local configuration interface configuration.
S3-1, server configuration mode:
the server associates the unconfigured machine position reported by the host machine position into the place where the host machine position is located (the unconfigured machine position in the host machine position uploading list in the step 2 is configured), and transmits the configuration information to the host machine position, the host machine position broadcasts the received slave machine position configuration information to other slave machine positions through UDP, and a notification protocol is broadcasted (a protocol header [0x300525] data type [0x03] length [0x18] content [ host machine position coding and setting time ] check code [0x52 ]).
The slave machine position stores the local machine position information matched with the received slave machine position configuration information into the current machine position, reports the configuration information of the current machine position successfully configured to the server side, and the server side receives the data reported from the slave machine position and changes the state into the state of successful configuration, which is shown in fig. 4.
S3-2, local configuration interface configuration mode:
the unconfigured machine position sets the address information, the field code and the mark information of the slave machine position through a local configuration interface, the configured information and the configured time are stored in a local database, and the local machine position information is reported to the server end through the server interface after the configuration is finished;
and after receiving the slave machine position configuration information, the server judges whether the slave machine position information exists, adds the slave machine position information if the slave machine position information does not exist, and updates the slave machine position information if the slave machine position information exists.
The data communication method of the invention comprises the following two methods:
a server and a machine position:
each machine position sends current machine position information to a server through an HTTP request at intervals, wherein the machine position information comprises: the method comprises the following steps of field coding, machine position coding, identification of a master machine position or a slave machine position, machine position configuration completion time, local network card IP list information and local MAC information; and the server returns the state to the machine position through the reporting state interface.
Machine position and machine position:
the machine positions are communicated in a UDP broadcast mode, and the broadcast notification protocol comprises the following steps: the protocol header takes a fixed value [0x300525], a data type [ type of communication data ], a data length [ byte length of data content ], a data content [ content required to be transmitted for communication ], and a data content check code [ last two bytes after data type, data length and data content are summed ].
