Description
Technical field
The present invention relates to the communications field, be specifically related to refer to a kind of technology of debugging single board serial ports mapping.
Background technology
In communication equipment, in order to improve the reliability of system, the service plane with system separates with management plane, Monitoring and Controlling plane usually, so just can avoid a plane operation irregularity to cause the collapse of whole system.Service plane is exactly the plane of process user business datum, and for example the IP message is handled and transmitted.Management plane is exactly the management of carrying out system, comprises initialization, software upgrading, system configuration, management maintenance of system etc.; The Monitoring and Controlling plane then is the work such as monitoring, equipment power-on and power-off control, system power supply and fan-status monitoring of environmental monitoring, veneer temperature and the voltage of finishing equipment.As shown in Figure 1,2 master control borads are arranged in a system, and the polylith veneer all has an independently MCM (Monitor and Control Module respectively on master control borad and veneer, promptly monitor and control module), the MCM module on master control borad and the veneer links together.
Please refer to Fig. 2, the master control borad in the system also is a 1+1 backup, and one is main usefulness, and other one is standby.MCM module on the master control borad is main MCM module, and the MCM module on other veneer is from the MCM module.Realize management by main MCM module from the MCM module.Communicate by the outband management bus from MCM module and main MCM module, the MCM module on every veneer can also be by RS232 serial ports (serial line interface that meets EIA/TIA RS-232-D standard) and single board communication.Every veneer all is to carry cpu system, and the software of oneself is arranged.So in order debugging, on veneer, to provide the RS232 serial ports of a debugging, to print Debugging message, loading procedure etc. when being used for debugging single board with easy to maintenance.
As shown in Figure 3, general (the also double simultaneously maintenance serial port of doing of the debug serial port of master control borad except master control borad, so generally all offering the user uses), the debug serial port of other veneer interface that all stays in, in the time of promptly in veneer is inserted in cabinet, can't see this debug serial port from the outside, the connector of this debug serial port is in veneer inside, so the user can not use this debug serial port.And general external two the RS232 serial ports that provide of master control borad, one is console (control) serial ports, one is Aux (backup) serial ports.The Console serial ports is generally used for configuration, the debugging of master control borad.The then general external MODEM of Aux serial ports is as the serial ports of remote maintenance.
When other veneer in need be to cabinet except master control borad carried out positioning problems, the effect of debug serial port was very obvious, can obtain a lot of running state information of veneer, start self check information from debug serial port; And can carry out some tests to veneer by debug serial port.When veneer was inserted in the cabinet, the debug serial port by this veneer came veneer is safeguarded and positioning problems if desired, generally can only pull out this piece veneer from cabinet, inserted good serial interface cable, veneer was inserted in the cabinet again.
As seen above-mentioned scheme has following shortcoming:
(1) inconvenient operation needs the plug veneer.
(2) after veneer is pulled out, the operation of veneer has also just been interrupted, and not only the operation business to on-line apparatus impacts; And current state information just do not had yet, and is unfavorable for the location of problem.
Summary of the invention
The invention provides a kind of system that carries out debugging single board serial ports mapping, with the problem that solves inconvenient operation in the prior art and can impact to the operation business of on-line apparatus.
For addressing the above problem, the invention provides following technical scheme:
A kind of system that carries out the mapping of debugging single board serial ports, comprise: master control borad, at least one veneer, described veneer is used for bearer service, described master control borad and veneer are physical connections and can carry out data communication, wherein, include first treatment system and main Monitoring and Controlling module on the described master control borad, the two connects by debug serial port; Described veneer includes respectively: second treatment system and from the Monitoring and Controlling module, the two connects by debug serial port, debug serial port by described veneer is passed to single board information described from the Monitoring and Controlling module, again by from the Monitoring and Controlling module single board information that receives being transmitted to the main Monitoring and Controlling module of described master control borad and exporting, and then realize the mapping of single board information on master control borad at master control borad.
Realize physical connection and carry out data communication by the outband management bus between described master control borad and veneer.
The main Monitoring and Controlling module of described master control borad also realizes being connected by the outband management bus from the Monitoring and Controlling module with veneer.

Embodiment
Please refer to Fig. 4, the corresponding system of the inventive method includes: master control borad, veneer 1 and veneer 2, described veneer 1 and veneer 2 are the veneer of bearer service, and 2 of described master control borad, veneer 1 and veneers are realized physical connection and data communication by the outband management bus.Wherein, include CPU mini system and Master MCM (Master Monitor Control Module: main Monitoring and Controlling module) on the described master control borad, described Master MCM act as: Master MCM is exactly the control centre of system monitoring control plane, its is responsible for other MCM module of whole system is managed, and comprises that configuration information issues, state collection and processing, report and alarm and process information; The Master MCM module temperature, voltage monitoring etc. of also being responsible for the master control borad at its place are similar to the function of slave MCM in addition, connect by the RS232 serial ports between described CPU mini system and Master MCM, on described CPU mini system, also be provided with backup (Aux) serial ports and control (Console) serial ports in addition with the extraneous usefulness of communicating by letter; All include CPU mini system and Slave MCM (Slave Monitor Control Module :) on described veneer 1 and the veneer 2 respectively from the Monitoring and Controlling module, described Slave MCM act as: the service board to the place carries out temperature, the monitoring of voltage, the last electric control of veneer, read the manufacturing information of veneer, connect by the RS232 serial ports between described CPU mini system and Slave MCM, in addition, also be respectively arranged with debug serial port on the CPU mini system of described veneer 1 and veneer 2, it act as: can print veneer from CPU brought into operation operation and self check information the complete start-up course, can also finish the program of veneer is carried out loading upgrading, in the veneer normal course of operation, also can be some important operation exception information, alarm, Debugging message outputs to debug serial port, is mainly used in the exploitation debugging of veneer, the purpose of case study location.
In the said system, communicate by the outband management bus between described master MCM and each slave MCM, they have constituted independently a communication and a control system.Wherein the outband management bus can adopt common RS485, CAN, I
2The C bus all has a single-chip microcomputer among described master MCM and each slave MCM, and then makes described master MCM and each slave MCM can not rely on separately CPU mini system on the plate and work alone.If veneer 1 outputs to the RS232 serial ports that is connected with slave MCM on the veneer 1 during the information of same that outputs to veneer 1 debug serial port, then these information are transmitted to master MCM on the master control borad by the slave MCM on the veneer 1, by master MCM the information of described debug serial port is sent to master control borad again, and the information of described debug serial port is shown on the Aux of master control borad serial ports.Like this, we just can realize the mapping of output on master control borad Aux serial ports of veneer 1 debug serial port.In like manner, can realize the mapping of input on master control borad Aux serial ports of debugging single board serial ports, its detailed process is: when the console serial port setting by master control borad specify the debugging single board serial ports after the mapping relations of master control borad Aux serial ports, in case the Aux serial ports of master control borad receives the information of input, master control borad will add message header to these information, represent that this is to send to the information of specifying the debugging single board serial ports, master control borad sends to Master MCM to the information that this adds behind the head then, Master MCM judges the message header of these data, discovery is to send to the debug serial port information of specifying veneer, then by and specify the serial-port between the Slave MCM that this information is transmitted to this Slave MCM, after this Slave MCM receives information, same judgement information header, discovery is to the information of the debugging single board serial ports of this MCM, then this information is transmitted to veneer.After specifying veneer to receive information, judgement is the serial ports map information to this plate, then removes information header and carries out the order of its effective information correspondence.
As seen, after realize mapping, the input and output that all carry out on master control borad Aux serial ports are just as carrying out on this veneer 1 debug serial port.
Please refer to Fig. 5, to appointment veneer 1, after the serial ports mapping is set, it is as follows that serial data flows to schematic diagram:
Master control borad provides the serial ports mapping directive, and this order can be carried out by the console serial ports of master control borad, and described serial ports mapping directive is specified the debug serial port of certain piece veneer is mapped on the Aux serial ports of master control borad;
After master control borad receives the order of serial ports mapping, by the RS232 serial ports that is connected with master MCM " mapping of specified slot position debugging single board serial ports " command messages is sent to master MCM, Master MCM is according to mapped veneer groove information, described command messages sent to the slave MCM in the veneer 1 of specified slot position correspondence by the outband management bus.
After slave MCM in the veneer 1 receives described command messages, more described command messages is sent to veneer, after described veneer receives described command messages, carries out following two processing:
(1) described veneer by with corresponding slave MCM between serial ports respond the message of one " correctly receiving mapping directive ", corresponding slave MCM sends to master MCM on the master control borad to this response message by the outband management bus, described Master MCM is transmitted to master control borad to this response message again, like this, the master control borad of main usefulness just knows that the serial ports mapping directive has correctly sent to veneer 1.
(2) veneer of appointment sends to the RS232 serial ports that is connected with MCM when sending to the information of same of this plate debug serial port, if receive the order that the mapping serial ports sends over simultaneously, then carry out this order (being that debug serial port by this plate issues just), simultaneously the result of command execution is outputed to the debug serial port of this plate and encapsulation and go up the MCM that sends to this plate behind the corresponding message header as these orders.
RS232 serial communication between veneer and the MCM is for the reliability that guarantees to communicate by letter and distinguish different data and News Category, has increased self-defining agreement, and data are encapsulated.The information such as frame length, classification sign indicating number, check byte that have Frame in the Frame of encapsulation.The classification of Frame comprises the Frame of serial ports mapping directive frame, serial ports mapping (enum) data frame, serial ports mapping acknowledgement frame, MCM module monitors management information self.
Carry out when specifying veneer sending to corresponding slave MCM after the encapsulation of Frame the information of same of debug serial port output.Slave MCM is according to the Frame classification information that receives, and judgement directly is transmitted to master MCM to Frame by the outband management bus after being serial ports mapped data frame.Master MCM if find to be meant the serial ports mapping (enum) data frame of order plate, then directly is transmitted to Frame the master control borad of main usefulness according to the Frame classification that receives.After the master control borad of main usefulness receives Frame, find that frame category is the serial ports mapping (enum) data frame that the specified slot position is brought, then these data messages are removed frames encapsulation, recover original data and give the Aux serially printing of this plate.
After the serial ports mapping directive successfully is set.Receive the order of this plate Aux serial ports when master control borad after, then this order is encapsulated as the command frame format of serial ports mapping, and is handed down to master MCM, after master MCM receives this command frame, judge that type is the command frame of serial ports mapping, then directly is transmitted to the slave MCM of specified slot position.After specified slot position slave MCM receives command frame, carry out the judgement of frame type equally earlier.If the command frame of serial ports mapping is then passed to veneer.After veneer received, judgement was the command frame of serial ports mapping, then removes the encapsulation of data, recovers original order and execution.
Cancel the serial ports mapping if desired, then can issue the order of cancellation serial ports mapping by the console serial ports of master control borad.Master control borad sends to master MCM to the order of removing mapping, and master MCM is transmitted to order according to slot number the slave MCM of corresponding groove position again.After the slave MCM of specified slot position receives order, again by veneer being issued in order with the serial ports of veneer.Veneer receives order, then cancels the mapping of serial ports.
The method of introducing above is the Aux serial ports that the debug serial port of appointment veneer is mapped to master control borad.If there is not the Aux serial ports on the master control borad, have only a console serial ports, also can realize the mapping of serial ports, idiographic flow is:
1, master control borad provides the serial ports mapping directive, and this order can be carried out by the console serial ports of master control borad, and described serial ports mapping directive is specified the debug serial port of certain piece veneer is mapped on the console serial ports of master control borad.
2, after master control borad receives the order of serial ports mapping, by the RS232 serial ports that is connected with master MCM " mapping of specified slot position debugging single board serial ports " command messages is sent to master MCM, MasterMCM is according to mapped veneer groove information, described command messages sent to the slave MCM in the veneer 1 of specified slot position correspondence by the outband management bus.
3, after the slave MCM in the veneer 1 receives described command messages, more described command messages is sent to veneer, after described veneer receives described command messages, carries out following two processing:
(1) described veneer by with corresponding slave MCM between serial ports respond the message of one " correctly receiving mapping directive ", corresponding slave MCM sends to master MCM on the master control borad to this response message by the outband management bus, described Master MCM is transmitted to master control borad to this response message again, like this, the master control borad of main usefulness just knows that the serial ports mapping directive has correctly sent to veneer 1.
(2) veneer of appointment sends to the RS232 serial ports that is connected with MCM when sending to the information of same of this plate debug serial port, if receive the order that the mapping serial ports sends over simultaneously, then carry out this order (being that debug serial port by this plate issues just), simultaneously the result of command execution is outputed to the debug serial port of this plate and encapsulation and go up the MCM that sends to this plate behind the corresponding message header as these orders.
4, the RS232 serial communication between veneer and the MCM has increased self-defining agreement for the reliability that guarantees to communicate by letter and distinguish different data and News Category, and data are encapsulated.The information such as frame length, classification sign indicating number, check byte that have Frame in the Frame of encapsulation.The classification of Frame comprises the Frame of serial ports mapping directive frame, serial ports mapping (enum) data frame, serial ports mapping acknowledgement frame, MCM module monitors management information self.
Carry out when 5, specifying veneer sending to corresponding slave MCM after the encapsulation of Frame the information of same of debug serial port output.Slave MCM is according to the Frame classification information that receives, and judgement directly is transmitted to master MCM to Frame by the outband management bus after being serial ports mapped data frame.Master MCM if find to be meant the serial ports mapping (enum) data frame of order plate, then directly is transmitted to Frame the master control borad of main usefulness according to the Frame classification that receives.After the master control borad of main usefulness receives Frame, find that frame category is the serial ports mapping (enum) data frame that the specified slot position is brought, then these data messages are removed the frame encapsulation, recover original data and give the console serially printing of this plate, and before the information that each bar is printed, increase a sign, the information of representing this printing is the output information of mapped debug serial port, is not the information of this master control borad oneself output.The sign that increases can software set, for example: @ groove position ID@sdram selftest pass! Used two @ symbols above, increase the slot number of mapped veneer between two @ symbols, the back is exactly the information of mapped serially printing.
6, after the serial ports mapping directive successfully is set.(this class order is different with the general action command of master control borad after needs that master control borad receives this plate console serial ports are mapped to the order of specifying veneer, for example can increase redirect special identifier symbol in this class order line front, represent that this order is the mapped orders of needs), then this order is encapsulated as the command frame format of serial ports mapping, and be handed down to master MCM, after masterMCM receives this command frame, judge that type is the command frame of serial ports mapping, then directly is transmitted to the slave MCM of specified slot position.After specified slot position slave MCM receives command frame, carry out the judgement of frame type equally earlier.If the command frame of serial ports mapping is then passed to veneer.After veneer received, judgement was the command frame of serial ports mapping, then removes the encapsulation of data, recovers original order and execution.
7, cancel the serial ports mapping if desired, then can issue the order of cancellation serial ports mapping by the console serial ports of master control borad.Master control borad sends to master MCM to the order of removing mapping, and master MCM is transmitted to order according to slot number the slave MCM of corresponding groove position again.After the slave MCM of specified slot position receives order, again by veneer being issued in order with the serial ports of veneer.Veneer receives order, then cancels the mapping of serial ports.
Distinctive points is:
1, whether some specifies the serial ports mapping directive of veneer owing to the order of importing on the master control borad console serial ports, but the order that master control borad self is carried out, so need in the definition of order line, distinguish, being that master control borad can be distinguished the order line of input, is the order of master control borad self execution or the order of mapped veneer.
2, also will to distinguish by the information of console serial ports output be the information of master control borad oneself output to master control borad, and the information of still mapped serial port of a board output can be at the information header of an identification of the information front of output increase.
The present invention is shone upon other serial port of a board except that master control borad, and the positioning problems when greatly facilitating debugging does not need to plug veneer and connects debug serial port; And to the equipment of online operation, when going wrong, be impossible allow the plug veneer, just can obtain the current veneer operation information that goes wrong very easily by this method.
By outband management bus and independently monitoring management module MCM in the system, except that master control borad other debugging single board serial ports in the system is mapped on the serial ports of master control borad (if master control borad has two serial ports, then can be mapped on the Aux serial ports of master control borad, if master control borad has only a console serial ports, also can be mapped on the console serial ports), serial ports by master control borad shows the information that shows on the debugging single board serial ports of specifying again, can control the veneer of appointment by this serial ports simultaneously, this serial ports of master control borad just looks like the debug serial port that is meant order plate self, can finish all functions of given plate debug serial port.
