Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.

In specific implementation, terminal described in the embodiment of the present invention can comprise the control terminal of state machine state conversion and carry out terminal, wherein, above-mentioned control terminal (also claiming to control node) and execution terminal (also claiming XM) form all nodes of distributed cluster system, it is the corresponding terminal of each node in distributed cluster system, this terminal can be control terminal, also can be execution terminal.In specific implementation, user can be according to predefined election regulation, from terminal corresponding to all nodes of group system, choose a terminal as the control terminal of the SOT state of termination machine state conversion of group system, in order to the execution terminal to group system, send the control message of state machine state conversion.Concrete, from all terminals of group system, elect a terminal as after control terminal, other terminal is for carrying out terminal; In addition, in the process that group system is being executed the task, when the control terminal that above-mentioned user chooses sends fault, system also can be chosen according to predefined selection rule one and carry out terminal as new control terminal from above-mentioned execution terminal, in order to carry out the task of control terminal, wherein, any one is carried out terminal and is all likely chosen for control terminal, specifically can determine according to predefined rule.In specific implementation, the control terminal of distributed cluster system and carry out terminal and specifically can be computer described in the embodiment of the present invention.

Referring to Fig. 1, it is the first embodiment schematic flow sheet of method of the state machine state conversion of the terminal that provides of the embodiment of the present invention.The method of the state machine state conversion of the terminal described in the present embodiment, comprises step:

S101, the executing state that control terminal is carried out terminal according to each sends the control message of state machine state conversion to all described execution terminals.

S102, respectively carries out the state information of terminal feedback described in described control terminal receives.

S103, described control terminal is according to the executing state of respectively carrying out terminal described in the described state information updating of respectively carrying out terminal feedback, to send the next control message of state machine state conversion to all described execution terminals according to the described executing state of respectively carrying out terminal after upgrading.

In some feasible execution modes, the control terminal described in the embodiment of the present invention comprises being used to indicate to the control message of carrying out the state machine state conversion that terminal sends carries out the status word that terminal is carried out state machine state conversion.For example, group system is when the function of software upgrade, need to complete following step: before the upgrading of legacy version software, detect, the unloading of legacy version software, the download of new version software, the installation of new version software, the startup of new version software and checking etc., above-mentioned each step is defined as to a state, be in the whole process of software upgrading, the SOT state of termination machine of system need to carry out front detect (referred to as first state) of upgrading of above-mentioned legacy version software, the unloading of legacy version software (referred to as the second state), the download of new version software (referred to as the third state), the installation of new version software (referred to as the 4th state), the conversion of the states such as the startup of new version software (referred to as the 5th state) and checking (referred to as the 6th state).In specific implementation, can preset status word corresponding to above-mentioned each state, for example, the status word that the first state is corresponding is A, the status word that the second state is corresponding is B, status word corresponding to the third state is C, the status word that the 4th state is corresponding is D, the status word that the 5th state is corresponding is E, the status word that the 6th state is corresponding is F etc., control terminal need to be carried out terminal and carry out state machine state when conversion, can send to all execution terminals the status word of state machine state conversion, for example, when carrying out terminal in the first state, when if control terminal need to be carried out terminal and is converted to the second state from the first state, can send status word B to carrying out terminal, carry out terminal and receive the state conversion that status word B can carry out state machine afterwards.

In some feasible execution modes, when control terminal starts to send the control message of state machine state conversion to execution terminal, because all execution terminals all also do not start to carry out the state conversion of state machine, therefore all residing states of execution terminal current state machine should be the first state, control terminal can directly transmit control message to all execution terminals according to each initial condition of carrying out terminal in system, be that control terminal can directly send status word B to all execution terminals, be used to indicate all execution terminals the state of state machine is converted to the second state from the first state.In specific implementation, after execution terminal receives the control message of control terminal transmission, can carry out state machine state conversion according to the status word in control message, and the executing state of state machine state conversion is fed back to control terminal, wherein, the executing state of above-mentioned state machine state conversion comprises the implementation progress that the residing state of current state machine and state machine carry out state conversion.For example, after execution terminal 1 receives the status word B of control terminal transmission, carry out 1, terminal and the state of its state machine can be converted to the second state from the first state, and the executing state of state machine state conversion can be fed back to control terminal.Concrete, can preset control terminal to the time interval of carrying out the control message of terminal transmission state machine state conversion, be that control terminal can regularly transmit control message to carrying out terminal, and control terminal is carried out the status word in terminal determines this transmission control message according to the executing state of the control message executing state conversion sending last time to carrying out the terminal Shi Junke that transmits control message according to each at every turn.While transmitting control message to execution terminal due to control terminal, this transmits control message and sent last time and controls hour life period interval, therefore can preset and carry out after terminal receives the control message that control terminal sends and carry out state machine state conversion, to the time interval of control terminal feedback execution state information, so that control terminal is grasped the executing state that each carries out terminal more exactly.For example, after execution terminal 1 receives status word B and carries out state machine state conversion, can be on default feedback time interval to control terminal feedback, carry out the executing state that terminal be carried out state machine state conversion, comprise that carrying out the residing state of terminal 1 current state machine (for example the second state) and execution terminal 1 carries out the implementation progress of state machine state conversion (for example 50%).

In some feasible execution modes, after control terminal receives each state information of carrying out terminal feedback, can carry out according to each executing state of each execution terminal of state information updating of terminal feedback, to send the next control message of state machine state conversion to all execution terminals according to each executing state of carrying out terminal after upgrading.In specific implementation, for example, when control terminal does not receive the state information of any one execution terminal (carrying out terminal 1) feedback within the predefined time, control terminal can preset carries out terminal 1 in short-duration failure state, the executing state that can keep carrying out terminal 1 when now control terminal upgrades the executing state that each carries out terminal is constant, and then the executing state of carrying out terminal according to each issues to all execution terminals the control message that sent last time again.After if control terminal repeatedly (comprises at least 2 times) control message that issues transmission last time, within the default time interval, also do not receive the state information of carrying out terminal 1 feedback, can judge and carry out terminal 1 in malfunction or disconnected, being control terminal described in the embodiment of the present invention also can have the function of heartbeat detection to carrying out the control message that terminal issues, and can whether carry out terminal in normal connection status according to the situation judgement of carrying out terminal feedback state information.In specific implementation, control terminal can receive after execution terminal sends next control message carries out terminal according to the state information of feedback after this control message executing state conversion, and then again upgrade according to the state information receiving the executing state that each carries out terminal, according to each executing state of carrying out terminal after upgrading, to each, carry out terminal again and issue next control message, so circulation is until all execution terminals execute all state machine state conversions.When all execution terminals execute all state conversions, group system can complete the upgrading of software.

In embodiments of the present invention, control terminal can send the control message of state machine state conversion simultaneously to all execution terminals, indication is carried out terminal and is carried out state machine state conversion, and each carries out the executing state of terminal according to the state information updating of all execution terminal feedbacks, be control command and the state synchronization unification of the state machine state conversion described in the present embodiment, improve control terminal and eliminated the reliability of scene extremely such as sequential and fault, improved the execution efficiency of state machine state conversion; Control terminal described in the present embodiment also can judge and whether carry out terminal in normal connection status according to the execution state information of carrying out the whether normal feedback states machine state conversion of terminal, further guaranteed the execution efficiency of state machine state conversion, the efficiency that has improved the SOT state of termination machine state conversion of system, has strengthened system availability and user and has experienced.

Referring to Fig. 2, it is the second embodiment schematic flow sheet of method of the state machine state conversion of the terminal that provides of the embodiment of the present invention.The method of the state machine state conversion of the terminal described in the present embodiment, comprises step:

S201, control terminal sends the initial status word of state machine state conversion to all execution terminals.

In some feasible execution modes, when control terminal starts to send the control message of state machine state conversion to execution terminal, because all execution terminals all also do not start to carry out the state conversion of state machine, therefore all residing states of execution terminal current state machine should be the first state, control terminal can be according to each initial condition of carrying out terminal in system directly to all execution terminals transmit control message (being that control terminal can directly send to all execution terminals the initial status word that state machine state be changed), be that control terminal can directly send status word B to all execution terminals, be used to indicate all execution terminals the state of state machine is converted to the second state from the first state.

S202, respectively carries out the state information of terminal feedback described in described control terminal receives.

S203, described control terminal is according to the executing state of respectively carrying out terminal described in the described state information updating of respectively carrying out terminal feedback.

In some feasible execution modes, in the control message that control terminal sends to all execution terminals, also can comprise: the execution object that carries out state conversion according to the status word in above-mentioned control message, in fact, above-mentioned execution object specifically can be in execution terminals all in system any one or a plurality of.The practical application request that is the control terminal function that can will realize according to system (carrying out of task) determines whether to need execution terminals all in system all to need to carry out state machine state conversion, or needs specifically which to carry out terminal by and carry out this function (concrete which execution terminal need to be carried out state machine state conversion).In specific implementation, for example in system, carry out, after terminal (carrying out terminal 1) receives the control message that control terminal sends, can first according to the execution object in control message, judge whether to carry out state machine state conversion, when carrying out terminal 1, according to the control message judgement receiving, learn that the execution object in control message comprises execution terminal 1, carry out 1, terminal and can carry out state machine state conversion according to the status word in control message, if judgement is learnt the execution object in control message and is not comprised execution terminal 1, carry out 1, terminal and do not carry out state machine state conversion.Concrete, when 1 judgement of execution terminal learns that need to carry out state machine state changes, after 1, terminal of execution can be carried out state machine state according to the status word in control message, and the executing state of state machine state conversion is fed back to control terminal; When 1 judgement of execution terminal learns that not needing to carry out state machine state changes, can directly to control terminal feedback, carry out the state of terminal 1 current state machine.Wherein, the executing state of above-mentioned state machine state conversion comprises the implementation progress that the residing state of current state machine and state machine carry out state conversion.For example, after execution terminal 1 receives the status word B of control terminal transmission, carry out 1, terminal and the state of its state machine can be converted to the second state from the first state, and the executing state of state machine state conversion can be fed back to control terminal.Concrete, can preset control terminal to the time interval of carrying out the control message of terminal transmission state machine state conversion, be that control terminal can regularly transmit control message to carrying out terminal, and control terminal is carried out the status word in terminal determines this transmission control message according to the executing state of the control message executing state conversion sending last time to carrying out the terminal Shi Junke that transmits control message according to each at every turn.While transmitting control message to execution terminal due to control terminal, this transmits control message and sent last time and controls hour life period interval, therefore can preset and carry out after terminal receives the control message that control terminal sends and carry out state machine state conversion, to the time interval of control terminal feedback execution state information, so that control terminal is grasped the executing state that each carries out terminal more exactly.For example, after execution terminal 1 receives status word B and carries out state machine state conversion, can be on default feedback time interval to control terminal feedback, carry out the executing state that terminal be carried out state machine state conversion, comprise that carrying out the residing state of terminal 1 current state machine (for example the second state) and execution terminal 1 carries out the implementation progress of state machine state conversion (for example 50%).

In some feasible execution modes, after control terminal receives each state information of carrying out terminal feedback, can carry out according to each executing state of each execution terminal of state information updating of terminal feedback.

S204, judges that all described execution terminal current state machines, whether in same state, if the determination result is YES, perform step S205, if the determination result is NO, performs step S207.

S205, whether the implementation progress of carrying out state machine state conversion according to each execution terminal judges the completion status machine state conversion of all execution terminals, if the determination result is YES, performs step S206, if the determination result is NO, performs step S207.

S206, issues the first status word of state machine state conversion, and returns to step S202 to described all execution terminals, continue to carry out above-mentioned steps.

S207, issues the second status word of state machine state conversion, and returns to step S202 to described all execution terminals, continue to carry out up step.

In some feasible execution modes, after control terminal receives each state information of carrying out terminal feedback, can carry out according to each executing state of each execution terminal of state information updating of terminal feedback, to send the next control message of state machine state conversion to all execution terminals according to each executing state of carrying out terminal after upgrading.In specific implementation, after control terminal upgrades each executing state of carrying out terminal, when control terminal will send next control message to all execution terminals, the status word of the state machine state conversion that can issue according to each Determines of carrying out terminal after upgrading.Concrete, the residing state of each execution terminal current state machine that control terminal can be carried out terminal feedback according to each judges whether all execution terminal current state machines are in same state (whether all execution terminals have all been carried out state conversion), if judgement learns that all execution terminal current state machines are all in same state, can judge and learn that all execution terminals have all successfully carried out state conversion, and then can carry out terminal according to each and carry out the implementation progress of state machine state conversion and judge whether whether all execution terminals have all completed state machine state conversion.For example, in the state information of all execution terminal feedbacks, show that all execution terminals carry out the implementation progress of state machine state conversion and be 100%, can judge and learn that all execution terminals have all completed the state conversion of state machine, now, control terminal can send to all execution terminals first status word (the first status word described in the embodiment of the present invention specifically can be status word corresponding to next state that state machine need to be carried out) of state machine state conversion; In the state information of feeding back, show the execution terminal of unfinished state machine state conversion in all execution terminals, in all execution terminals, there is one or more implementation progress of carrying out terminal not reach 100%, can judge and learn and carry out in addition terminal unfinished state machine state conversion, now, control terminal can send to all execution terminals second status word (the second status word described in the embodiment of the present invention specifically can be the status word corresponding to state of the current execution of state machine) of state machine state conversion.When control terminal judgement learns that according to the state information judgement of all execution terminal feedbacks not every execution terminal is all in same state, exist indivedual terminals of carrying out also in Last status, and not successfully proceed to state corresponding to status word in the control message that control terminal sends, now, control terminal can send to all execution terminals the second status word of state machine state conversion.In specific implementation, control terminal can receive after execution terminal sends next control message carries out terminal according to the state information of feedback after this control message executing state conversion, and then again upgrade according to the state information receiving the executing state that each carries out terminal, according to each executing state of carrying out terminal after upgrading, to each, carry out terminal again and issue next control message, so circulation is until all execution terminals execute all state machine state conversions.When all execution terminals execute all state conversions, group system can complete the upgrading of software.The control command of the state machine state conversion described in the present embodiment and state synchronization unification, improved control terminal and eliminated the reliability of scene extremely such as sequential and fault, improved the execution efficiency of state machine state conversion.

In some feasible execution modes, control terminal has been set each and has been carried out terminal after the time interval of control terminal feedback states information, control terminal also can according to carry out terminal whether within the default time interval successful feedback information judge that whether this execution terminal is in normal connection status.For example, for example, when control terminal does not receive the state information of any one execution terminal (carrying out terminal 1) feedback within the predefined time, control terminal can preset carries out terminal 1 in short-duration failure state, the executing state that can keep carrying out terminal 1 when now control terminal upgrades the executing state that each carries out terminal is constant, and then the executing state of carrying out terminal according to each issues to all execution terminals the control message that sent last time again.After if control terminal repeatedly (comprises at least 2 times) control message that issues transmission last time, within the default time interval, also do not receive the state information of carrying out terminal 1 feedback, can judge and carry out terminal 1 in malfunction or disconnected, being control terminal described in the embodiment of the present invention also can have the function of heartbeat detection when carrying out the control message that terminal issues, can whether carry out terminal in normal connection status according to the situation judgement of carrying out terminal feedback state information, further guaranteed the execution efficiency of state machine state conversion, having strengthened system availability and user experiences.

In some feasible execution modes, in the control message that control terminal described in the invention process sends to execution terminal, also can comprise: node hierarchy information, above-mentioned node hierarchy information comprises the residing node grade of each execution terminal, or the next stage that each execution terminal is managed is carried out the information of terminal, wherein, the information of above-mentioned next stage execution terminal comprises: next stage is carried out the number of terminal and the sign of each execution terminal etc.In specific implementation, when group system larger, in order to guarantee that system has higher reliabilty and availability, all nodes in system can be carried out to classification, (as Fig. 3) such as one-level node, two-level node, three grades of nodes, and set carrying out terminal, to carry out the transmission rule of the control message that state machine state changes be the control message of higher leveled node to node (being the next stage node of its management) the transfer control node transmission of its next stage, wherein one-level node grade is higher than two-level node, and the grade of two-level node is higher than three grades of nodes etc.Set the node grade under each execution terminal in system, or after the next stage that each execution terminal is managed is carried out the information of terminal, control terminal sends status word and the node hierarchy information of state machine state conversion to all execution terminals executing state that Shi Zeke carries out terminal according to each that transmits control message to all execution terminals, by above-mentioned status word, indicate each to carry out terminal and carry out state machine state conversion, and by the corresponding terminal of carrying out of above-mentioned node hierarchy information indication, control information is handed down to the next stage execution terminal that this execution terminal is managed.As Fig. 3, if system comprises 7 nodes, can pre-define control terminal is one-level node, and define 2 two-level nodes, two three grades of nodes of each two-level node management, control terminal can transmit control message to two-level node (for example message 1), and message 1 comprises that two-level node need to carry out the information that next stage that the status word of state machine state conversion and the residing node grade of two-level node (being secondary) and two-level node manage is carried out terminal (three grades of nodes).Two-level node can issue the control message (for example message 2) that control terminal sends to three grades of nodes after receiving message 1, and message 2 comprises that three grades of nodes need to carry out the information of the next stage execution terminal (0) that the status word of state machine state conversion and three grades of residing node grades of node (three grades) and three grades of nodes manage.In specific implementation, each execution terminal can and be fed back corresponding state information to control terminal according to the status word executing state machine state conversion in control message after receiving control message.Concrete, as Fig. 3, three grades of nodes can be by status information feedback to two-level node (as message 4), after two-level node receives the message of three grades of nodes transmissions, can need to feed back to control terminal feedack to control terminal corresponding state information (as message 3) in conjunction with himself, the executing state of the next stage of the executing state of himself and management thereof being carried out to terminal feeds back to control terminal, and control terminal can be known according to two-level node feedack the executing state of all execution terminals in system.

In some feasible execution modes, the embodiment of the present invention, by the method for system node classification, makes system can support arbitrary node fault, the reliability of safeguards system.As Fig. 4, for example, when arbitrary node in system (one-level node) breaks down, system also can, according to predefined selection rule, be chosen new one-level node, the task of taking over former one-level node from all two-level nodes.For example, when some two-level nodes do not receive the message of one-level node within the default time interval, this two-level node can be chosen for to new one-level node, by this new one-level node, to other nodes, transmit control message, guarantee the normal operation of system.The embodiment of the present invention adopts the method for system node classification, by even higher level of node to photos and sending messages under next stage node or obtain the state information of next stage node by even higher level of node, can reduce the congested of node messages, solve the node messages bottleneck problem of large-scale cluster system, improved the efficiency of SOT state of termination machine state conversion of system and the reliability of system, the availability and the user that have strengthened system experience.

In embodiments of the present invention, control terminal can send the control message of state machine state conversion simultaneously to all execution terminals, indication is carried out terminal and is carried out state machine state conversion, and each carries out the executing state of terminal according to the state information updating of all execution terminal feedbacks, be control command and the state synchronization unification of the state machine state conversion described in the present embodiment, improve control terminal and eliminated the reliability of scene extremely such as sequential and fault, improved the execution efficiency of state machine state conversion; Control terminal described in the present embodiment also can judge and whether carry out terminal in normal connection status according to the execution state information of carrying out the whether normal feedback states machine state conversion of terminal, node hierarchy that also can back-up system, further guaranteed the execution efficiency of state machine state conversion, improved the efficiency of SOT state of termination machine state conversion of system and the reliability of large-scale cluster system, strengthened system availability and user and experienced.

Referring to Fig. 5, it is the first example structure schematic diagram of the control terminal of the state machine state conversion that provides of the embodiment of the present invention.Control terminal described in the present embodiment, comprising:

Sending module 10 sends the control message of state machine state conversion for carrying out the executing state of terminal according to each to all described execution terminals, described control message comprises and is used to indicate the status word that described execution terminal is carried out state machine state conversion.

Receiver module 20, for respectively carrying out the state information of terminal feedback described in receiving, to be described execution terminal carry out the execution state information of feedback after state machine state conversion according to described control message to described state information.

Update module 30, for according to the executing state of respectively carrying out terminal described in the described state information updating of respectively carrying out terminal feedback, to send the next control message of state machine state conversion by described sending module to all described execution terminals according to the described executing state of respectively carrying out terminal after upgrading.

In some feasible execution modes, the sending module 10 of the control terminal described in the embodiment of the present invention comprises being used to indicate to the control message of carrying out the state machine state conversion that terminal sends carries out the status word that terminal is carried out state machine state conversion.For example, group system is when the function of software upgrade, need to complete following step: before the upgrading of legacy version software, detect, the unloading of legacy version software, the download of new version software, the installation of new version software, the startup of new version software and checking etc., above-mentioned each step is defined as to a state, be in the whole process of software upgrading, the SOT state of termination machine of system need to carry out front detect (referred to as first state) of upgrading of above-mentioned legacy version software, the unloading of legacy version software (referred to as the second state), the download of new version software (referred to as the third state), the installation of new version software (referred to as the 4th state), the conversion of the states such as the startup of new version software (referred to as the 5th state) and checking (referred to as the 6th state).In specific implementation, can preset the status word that above-mentioned each state is corresponding and be stored in control terminal, for example, can preset the status word that the first state is corresponding is A, the status word that the second state is corresponding is B, status word corresponding to the third state is C, the status word that the 4th state is corresponding is D, the status word that the 5th state is corresponding is E, the status word that the 6th state is corresponding is F etc., control terminal need to be carried out terminal and carry out state machine state when conversion, can to all execution terminals, send by sending module 10 status word of state machine state conversion, for example, when carrying out terminal in the first state, when if control terminal need to be carried out terminal and is converted to the second state from the first state, can to carrying out terminal, send status word B by sending module 10, carry out terminal and receive the state conversion that status word B can carry out state machine afterwards.

In some feasible execution modes, when control terminal, need to carry out terminal and carry out state machine state conversion, and start when carrying out terminal and send the control message of state machine state conversion by sending module 10, because now all execution terminals all also do not start to carry out the state conversion of state machine, therefore all residing states of execution terminal current state machine should be the first state, control terminal can directly transmit control message to all execution terminals according to each initial condition of carrying out terminal in system, be that sending module 10 can directly send status word B to all execution terminals, be used to indicate all execution terminals the state of state machine is converted to the second state from the first state.In specific implementation, after execution terminal receives the control message of control terminal transmission, can carry out state machine state conversion according to the status word in control message, and the executing state of state machine state conversion is fed back to control terminal, wherein, the executing state of above-mentioned state machine state conversion comprises the implementation progress that the residing state of current state machine and state machine carry out state conversion.For example, after execution terminal 1 receives the status word B of control terminal transmission, carry out 1, terminal and the state of its state machine can be converted to the second state from the first state, and the executing state of state machine state conversion can be fed back to control terminal.Concrete, can preset sending module 10 to the time interval of carrying out the control message of terminal transmission state machine state conversion, be that control terminal can regularly transmit control message to carrying out terminal by sending module 10, and sending module 10 is carried out the status word in terminal determines this transmission control message according to the executing state of the control message executing state conversion sending last time to carrying out the terminal Shi Junke that transmits control message according to each at every turn.While transmitting control message to execution terminal due to sending module 10, this transmits control message and sent last time and controls hour life period interval, therefore can preset and carry out after terminal receives the control message that control terminal sends and carry out state machine state conversion, to the time interval of control terminal feedback execution state information, so that control terminal is grasped the executing state that each carries out terminal more exactly.For example, after execution terminal 1 receives status word B and carries out state machine state conversion, can be on default feedback time interval to control terminal feedback, carry out the executing state that terminal be carried out state machine state conversion, comprise that carrying out the residing state of terminal 1 current state machine (for example the second state) and execution terminal 1 carries out the implementation progress of state machine state conversion (for example 50%).

In some feasible execution modes, after control terminal receives each state information of carrying out terminal feedback by receiver module 20,30 of update module can be carried out according to each executing state of each execution terminal of state information updating of terminal feedback, and each executing state of carrying out terminal after sending module 10 can upgrade according to update module 30 sends the next control message of state machine state conversion to all execution terminals.In specific implementation, for example, when the receiver module 20 of control terminal does not receive the state information of any one execution terminal (carrying out terminal 1) feedback within the predefined time, control terminal can preset carries out terminal 1 in short-duration failure state, the executing state that can keep carrying out terminal 1 when now the update module 20 of control terminal is upgraded the executing state that each carries out terminal is constant, and then the executing state of carrying out terminal according to each by sending module 30 issues to all execution terminals the control message that sent last time again.After if sending module more than 10 time (comprising at least 2 times) issues the control message sending last time, receiver module 20 does not also receive the state information of carrying out terminal 1 feedback within the default time interval, control terminal can judge to be carried out terminal 1 in malfunction or has disconnected, control terminal described in the embodiment of the present invention that hence one can see that also can have the function of heartbeat detection when carrying out the control message that terminal issues, and can whether carry out terminal in normal connection status according to the situation judgement of carrying out terminal feedback state information.In specific implementation, control terminal by sending module 10 to carrying out after terminal sends next control message, receiver module 20 can receive carries out terminal according to the state information of feedback after this control message executing state conversion, and then the state information receiving according to receiver module 20 by update module 30 is upgraded the executing state that each carries out terminal again, sending module 10 is carried out terminal according to each executing state of carrying out terminal after upgrading to each again and is issued next control message, so circulation is until all execution terminals execute all state machine state conversions.When all execution terminals execute all state conversions, group system can complete the upgrading of software.

Referring to Fig. 6, it is the second example structure schematic diagram of the control terminal of the state machine state conversion that provides of the embodiment of the present invention.Control terminal described in the present embodiment, comprising:

Sending module 40 sends the control message of state machine state conversion for carrying out the executing state of terminal according to each to all described execution terminals, described control message comprises and is used to indicate the status word that described execution terminal is carried out state machine state conversion.

In some feasible execution modes, above-mentioned sending module 40, comprising:

The first judging unit 41, for judging that according to the described residing state of terminal current state machine of respectively carrying out whether all described execution terminal current state machines are in same state;

Whether the second judging unit 42, while for judgment result is that at described the first judging unit being, carrying out the implementation progress of state machine state conversion and judge the completion status machine state conversion of described all described execution terminals according to the described terminal of carrying out described in each;

Transmitting element 43, while for judgment result is that at described the second judging unit being, issues the first status word of state machine state conversion to described all described execution terminals;

Described transmitting element 43, when the determination result is NO at described the second judging unit, issues the second status word of state machine state conversion to described all described execution terminals;

Described transmitting element 43, also when the determination result is NO at described the first judging unit, issues the second status word of state machine state conversion to described all described execution terminals.

In some feasible execution modes, the sending module 40 of the control terminal described in the embodiment of the present invention comprises being used to indicate to the control message of carrying out the state machine state conversion that terminal sends carries out the status word that terminal is carried out state machine state conversion.For example, group system is when the function of software upgrade, need to complete following step: before the upgrading of legacy version software, detect, the unloading of legacy version software, the download of new version software, the installation of new version software, the startup of new version software and checking etc., above-mentioned each step is defined as to a state, be in the whole process of software upgrading, the SOT state of termination machine of system need to carry out front detect (referred to as first state) of upgrading of above-mentioned legacy version software, the unloading of legacy version software (referred to as the second state), the download of new version software (referred to as the third state), the installation of new version software (referred to as the 4th state), the conversion of the states such as the startup of new version software (referred to as the 5th state) and checking (referred to as the 6th state).In specific implementation, can preset the status word that above-mentioned each state is corresponding and be stored in control terminal, for example, can preset the status word that the first state is corresponding is A, the status word that the second state is corresponding is B, status word corresponding to the third state is C, the status word that the 4th state is corresponding is D, the status word that the 5th state is corresponding is E, the status word that the 6th state is corresponding is F etc., control terminal need to be carried out terminal and carry out state machine state when conversion, can to all execution terminals, send by sending module 40 status word of state machine state conversion, for example, when carrying out terminal in the first state, when if control terminal need to be carried out terminal and is converted to the second state from the first state, can to carrying out terminal, send status word B by sending module 40, carry out terminal and receive the state conversion that status word B can carry out state machine afterwards.

In some feasible execution modes, when control terminal, want to carry out terminal and carry out state machine state conversion, and start by sending module 40 when carrying out terminal and send the control message of state machine state conversion, because now all execution terminals all also do not start to carry out the state conversion of state machine, therefore all residing states of execution terminal current state machine should be the first state, control terminal can be according to each initial condition of carrying out terminal in system directly to all execution terminals transmit control message (being that sending module 40 can directly send to all execution terminals the initial status word that state machine state be changed), be that sending module 40 can directly send status word B to all execution terminals, be used to indicate all execution terminals the state of state machine is converted to the second state from the first state.

In some feasible execution modes, in the control message that the sending module 40 of control terminal sends to all execution terminals, also can comprise: the execution object that carries out state conversion according to the status word in above-mentioned control message, in fact, above-mentioned execution object specifically can be in execution terminals all in system any one or a plurality of.The practical application request that is the control terminal function that can will realize according to system (carrying out of task) determines whether to need execution terminals all in system all to need to carry out state machine state conversion, or needs specifically which to carry out terminal by and carry out this function (concrete which execution terminal need to be carried out state machine state conversion).In specific implementation, for example in system, carry out, after terminal (carrying out terminal 1) receives the control message that control terminal sends, can first according to the execution object in control message, judge whether to carry out state machine state conversion, when carrying out terminal 1, according to the control message judgement receiving, learn that the execution object in control message comprises execution terminal 1, carry out 1, terminal and can carry out state machine state conversion according to the status word in control message, if judgement is learnt the execution object in control message and is not comprised execution terminal 1, carry out 1, terminal and do not carry out state machine state conversion.Concrete, when 1 judgement of execution terminal learns that need to carry out state machine state changes, after 1, terminal of execution can be carried out state machine state according to the status word in control message, and the executing state of state machine state conversion is fed back to control terminal; When 1 judgement of execution terminal learns that not needing to carry out state machine state changes, can directly to control terminal feedback, carry out the state of terminal 1 current state machine.Wherein, the executing state of above-mentioned state machine state conversion comprises the implementation progress that the residing state of current state machine and state machine carry out state conversion.For example, after execution terminal 1 receives the status word B of control terminal transmission, carry out 1, terminal and the state of its state machine can be converted to the second state from the first state, and the executing state of state machine state conversion can be fed back to control terminal.Concrete, can preset the sending module 40 of control terminal to the time interval of carrying out the control message of terminal transmission state machine state conversion, be that sending module 40 can regularly transmit control message to carrying out terminal, and sending module 40 is carried out the status word in terminal determines this transmission control message according to the executing state of the control message executing state conversion sending last time to carrying out the terminal Shi Junke that transmits control message according to each at every turn.While transmitting control message to execution terminal due to sending module 40, this transmits control message and sent last time and controls hour life period interval, therefore can preset and carry out after terminal receives the control message that control terminal sends and carry out state machine state conversion, to the time interval of control terminal feedback execution state information, so that control terminal is grasped the executing state that each carries out terminal more exactly.For example, after execution terminal 1 receives status word B and carries out state machine state conversion, can be on default feedback time interval to control terminal feedback, carry out the executing state that terminal be carried out state machine state conversion, comprise that carrying out the residing state of terminal 1 current state machine (for example the second state) and execution terminal 1 carries out the implementation progress of state machine state conversion (for example 50%).

In some feasible execution modes, after control terminal receives each state information of carrying out terminal feedback by receiver module 20,30 of update module can be carried out according to each executing state of each execution terminal of state information updating of terminal feedback.After the receiver module 20 of control terminal receives each state information of carrying out terminal feedback, 30 of update module can be carried out according to each executing state of each execution terminal of state information updating of terminal feedback, and sending module 40 can send the next control message of state machine state conversion according to each executing state of carrying out terminal after upgrading to all execution terminals.In specific implementation, after control terminal upgrades each executing state of carrying out terminal by update module 30, when control terminal will send next control message to all execution terminals, the status word of the state machine state conversion that each Determines of carrying out terminal after 40 of sending modules can upgrade according to update module 30 issues.Concrete, each residing state of each execution terminal current state machine of carrying out terminal feedback that the first judging unit 41 of sending module 40 can receive according to receiver module 20 judges whether all execution terminal current state machines are in same state (whether all execution terminals have all been carried out state conversion), if the first judging unit 41 judgements learn that all execution terminal current state machines are all in same state, can judge and learn that all execution terminals have all successfully carried out state conversion, the second 42 of judging units can be carried out terminal according to each and carry out the implementation progress of state machine state conversion and judge whether whether all execution terminals have all completed state machine state conversion.For example, in learning the state information of all execution terminal feedbacks, the second judging unit 41 judgement shows that all execution terminals carry out the implementation progress of state machine state conversion and be 100%, can judge and learn that all execution terminals have all completed the state conversion of state machine, now, control terminal can send first status word (the first status word described in the embodiment of the present invention specifically can be status word corresponding to next state that state machine need to be carried out) of state machine state conversion by the transmitting element 43 of sending module 40 to all execution terminals, when the execution terminal that shows the conversion of unfinished state machine state in the state information of feeding back in all execution terminals is learnt in the second judging unit 41 judgements, in all execution terminals, there is one or more implementation progress of carrying out terminal not reach 100%, can judge and learn and carry out in addition terminal unfinished state machine state conversion, now, control terminal can send by transmitting element 43 second status word (the second status word described in the embodiment of the present invention specifically can be the status word corresponding to state of the current execution of state machine) of state machine state conversion to all execution terminals.When the first judging unit 41 judgements learn that according to the state information judgement of all execution terminal feedbacks not every execution terminal is all in same state, exist indivedual terminals of carrying out also in Last status, and not successfully proceed to state corresponding to status word in the control message that control terminal sends, now, by 43 of transmitting elements, can send to all execution terminals the second status word of state machine state conversion.In specific implementation, sending module 40 is after execution terminal sends next control message, receiver module 20 can receive carries out the rear state information of feeding back of control message executing state conversion that terminal sends according to sending module 40, the state information that update module 30 can receive according to receiver module 20 is upgraded each executing state of carrying out terminal again, each executing state of carrying out terminal after sending module 40 can upgrade according to update module 30 is carried out terminal to each and is issued next control message, so circulation is until all execution terminals execute all state machine state conversions.When all execution terminals execute all state conversions, group system can complete the upgrading of software.The control command of the state machine state conversion that the control terminal described in the present embodiment sends and state synchronization unification, can improve the reliability that control terminal is eliminated the abnormal scene such as sequential and fault, improved the execution efficiency of state machine state conversion.

In some feasible execution modes, control terminal has been set each and has been carried out terminal after the time interval of control terminal feedback states information, also can according to carry out terminal whether within the default time interval successful feedback information judge that whether this execution terminal is in normal connection status.For example, for example, when receiver module 20 does not receive the state information of any one execution terminal (carrying out terminal 1) feedback within the predefined time, control terminal can preset carries out terminal 1 in short-duration failure state, the executing state that can keep carrying out terminal 1 when now the update module 30 of control terminal is upgraded the executing state that each carries out terminal is constant, and then the executing state of carrying out terminal in conjunction with each by sending module 40 issues to all execution terminals the control message that sent last time again.After if control terminal issues by sending module more than 40 time (comprising at least 2 times) control message sending last time, receiver module 20 does not also receive the state information of carrying out terminal 1 feedback within the default time interval, can judge and carry out terminal 1 in malfunction or disconnected, being control terminal described in the embodiment of the present invention also can have the function of heartbeat detection to carrying out the control message that terminal issues, can whether carry out terminal in normal connection status according to the situation judgement of carrying out terminal feedback state information, further guaranteed the execution efficiency of state machine state conversion, having strengthened system availability and user experiences.

In some feasible execution modes, in the control message of the described state machine state conversion that above-mentioned sending module 40 sends, also comprise: node hierarchy information, described in described node hierarchy information comprises, respectively carry out the residing node grade of terminal, or describedly respectively carry out the information that next stage that terminal manages is carried out terminal;
