Embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of multi-protocol transmission device, including control module 1, access modules 2, AM access module 3, carrying mould
Block 4, configuration module 5, memory module 6, control module 1 are connected with access modules 2 and configuration module 5 respectively, the access modules 2
It is connected with AM access module 3, the AM access module 3 is connected with carrier module 4, and the configuration module 5 is connected with memory module 6.
Described carrier module 4 is connected with outside network management interface or network management path 7, and connected mode supports RS232, TCP/IP
With the physical channel of tri- kinds of protocol modes of UDP.The traffic flow information from outside network management interface or network management path 7 is received, by number
According to spreading into AM access module 3.
The data flow that described AM access module 3 is transmitted to carrier module 4 is verified, and successively data flow is followed successively by:Starting
Mark, data cell（PDU）, verification unit, the part of end mark four.
Wherein：Beginning flag accounts for a byte（It can customize）；Data cell（PDU）To access the payload of layer protocol
（PDU）；Verification unit verifies to the content of PDU in agreement, generates check value according to communication bag PDU, verification unit uses
CRC check, sender generate the CRC check of 2 bytes according to communication bag（Low byte is preceding during transmission, and high byte is rear）, equally,
After recipient receives complete packet, new CRC check value is generated according to communication bag, if the crc value and receipts that are calculated
To check value it is identical, show that the packet is effective, otherwise it is assumed that the bag generates mistake during transmission；Terminate mark
Will accounts for a byte（It can customize）.
To prevent from occurring in data flow starting over mark, in addition to frame head postamble, transmit in data and the word of the mark occur
Symbol carries out escape processing, to differentiate old agreement.In the case of being sent after needing progress escape, grasped according to following order
Make：Before sending packet, CRC check value is first generated, then carry out escape processing；After receiving packet, first carry out at escape
Reason, then carry out CRC check.
Data flow is finally passed to access modules 2.
The address and bag sequence number that described access modules 2 transmit to AM access module 3 verify, and realize monitoring key-course
Isolate with communication link, network structure, there is provided packet addressing processing, Route Selection and block functions, the priority number of use
It is followed successively by according to stream:Version number, reserved field, address location, communication bag identification number and the part of data cell five composition.
Wherein：Version number accounts for a byte（It can customize）；Reserved field accounts for a byte（It can customize）；Address location
For the station number of equipment, four bytes are accounted for（It can customize）；Communication bag identification number is the unique identifier number of each communication bag, by sending out
The one end for playing communication produces, and accounts for two bytes, 0 is turned to after counting maximum.Receiving terminal is not handled upon receipt, but
This value is intactly sent back into originating end when returning, in order to which originating end differentiates communication bag.Can low byte in transmission
Preceding, high byte is rear.
Data flow is finally passed to control module 1.
Described control module 1 receives the data flow from access modules 2, and main realize is supervised to each site apparatus
Control the transmission of instruction, receive, define the data tissue and data structure towards monitoring function, including by order unit and data
Unit forms.
Wherein：Order unit is made up of command id and answer logo, and command id is the unique identifying number of order, response
Indicate the active initiator as order, account for a byte（It can customize）, this bag is represented as order, when the order received
When not being the byte in bag field, then passive recipient does not reply；Data cell is used to carry monitoring data, in data cell
One or more monitoring datas can once be loaded.To improve the efficiency of transmission of monitoring information, in a communication process, should fill
Carry monitoring data as much as possible.Data cell may include the numerical value of multiple bytes, in order to ensure to the correct of these numerical value
Parsing, can to transmission when byte stream order be specified below：Low byte is preceding, and high byte is rear.
Described control module 1 is analyzed the data flow of access modules 2, and being configured should in unit reading memory cell
The address number of website, if the website is not meant to the terminal of monitoring, again by data flow successively through accessing mould after control module 1
Block 2, AM access module 3, carrier module 4, which pass back to, is passed to next website in network management path.If the website is the terminal to be monitored,
Data flow is then passed to configuration module 5.
Described configuration module 5 receives the data flow from control module 1, analyzes read-write operation, when sending read command,
Ensure that equipment can return to a querying command with a bag（Ensure that returning to length can be put into a communication bag, and
Monitoring data can intactly be put into communication bag）.During reading, monitoring data " monitoring data value " partly according to agreement in about
Fixed length inserts numerical value, and correctly fills in the value of " monitoring data length ", and equipment is not upon receipt to " monitoring data
Value " is partly handled, and ensures that hair, the communication bag quantity received are consistent；When sending write order, one or same can be once set
When multiple configuration datas are configured.The character string type object of maximum length is specify only for those, is supervised in setting command
The quantity that can be supported in control data value according to maximum length inserts set content, if set content length is not up to maximum, end
Part can all insert same byte（It can customize）, as mark.
Instruction and content of the configuration module 5 to the data flow of control module 1 are read and write in memory module 6.
Described memory module 6 receives the command information of configuration module 5, the vendor code of storage site equipment, device class,
Unit type, software and hardware version, PLD version and its IP address, subnet mask, gateway ip address, UDP
With Transmission Control Protocol port numbers, device mac address and polymerization subnet information etc..
