Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
A method for handling multiple redundancy states according to the present invention is described below with reference to fig. 1-5.
Specifically, the processing method of multiple redundant states provided by the present invention is applied to a first standby control center host, wherein the first standby control center host may be a gateway computer standby control center host or an application server standby control center host.
When the first master control center host is a gateway computer master control center host, and the second master control center host is an application server master control center host. When the first standby control center host is the application server standby control center host, the first main control center host in the invention is the application server main control center host, and the second main control center host comprises a gateway computer main control center host.
It should be noted that the first and second embodiments of the present invention are only used to distinguish the application server from the gateway computer, and in the quadruple redundancy scheme, four software deployed in the active/standby control center is simultaneously operated in a hot standby mode. The master and standby states of the four redundant devices are managed by the software redundant platform and switched, and the specific switching priority is as follows: the main control center host computer- > main control center standby computer- > standby control center host computer- > standby control center standby computer.
In the present invention, the gateway computer standby control center host is taken as a representative explanation, and the processing method of the multiple redundant states of the application server standby control center host is the same as that of the gateway computer standby control center host, and the description of the present invention is omitted here.
Fig. 1 is a schematic flow chart of a method for processing multiple redundancy states according to the present invention, as shown in fig. 1, the method includes:
step S1, under the condition that the communication link failure of the first main control center host is detected, analyzing the redundant equipment state frame fed back by the second main control center host to obtain the number of the redundant equipment and the identification of each redundant equipment;
specifically, there is a communication connection between the master and slave control centers of the gateway computer, referring to fig. 2, in fig. 2, the gateway computer OCC-a is a master control center host of the gateway computer, the gateway computer OCC-B is a master control center slave of the gateway computer, the gateway computer BOCC-a is a master control center host of the gateway computer, and the gateway computer OCC-B is a master control center slave of the gateway computer, wherein redundant devices are directly networked between each master control center host and each master control center slave, and the four redundant devices are connected through an intranet communication of the ATS system. And when the standby control center of the gateway computer cannot receive the working state of the master control center of the gateway computer, judging that the host of the master control center is in communication broken link.
Specifically, the number of redundant devices is a character with a byte length of 1, the number of redundant devices refers to the number of hosts of the gateway computer connected to the host of the application server main control center, the number of redundant devices is a character with a byte length of 2, and the number of redundant devices refers to the host ID of the gateway computer connected to the host of the application server main control center.
In practical application, when the host of the gateway computer connected to the host of the application server main control center includes the host of the gateway computer main control center and the host of the gateway computer standby control center, the number of the redundant devices is 2, and the redundant device identifier includes the host ID of the gateway computer main control center and the host ID of the gateway computer standby control center. When the host of the gateway computer connected with the application server main control center host only comprises the gateway computer standby control center host, the number of the redundant equipment is 1, and the redundant equipment identification comprises the ID of the gateway computer standby control center host.
Step S2, when the redundant device identification contains a first main control center host computer identification and the redundant device number meets the preset redundant device number, the first main control center host computer is judged to work normally and the standby control state is maintained.
Specifically, the number of the preset redundant devices is 2. In the step, under the condition that the redundant equipment identification comprises the ID of the main control center host of the gateway computer and the number of the redundant equipment is 2, the working state of the main control center host of the gateway computer is judged to be still normal, and the main control center host of the gateway computer is eliminated from being required to be increased, so that the system reliability is improved, and the problem of double main control of the control center is avoided.
The processing method of the multiple redundant states provided by the invention analyzes the redundant equipment state frame fed back by the host of the second main control center under the condition of detecting that the communication link breaking occurs to the host of the first main control center, and obtains the number of redundant equipment and the identification of each redundant equipment; and under the condition that the redundant equipment identification contains a first main control center host identification and the number of the redundant equipment meets the preset number of the redundant equipment, judging that the first main control center host normally works and maintaining a standby control state, and determining the number of the hosts which are working currently and the host identification through a redundant equipment state frame so as to judge whether the standby control center needs to be raised, thereby improving the reliability of the system.
In another embodiment, referring to fig. 3, fig. 3 is a second schematic flow chart of the processing method for multiple redundancy states provided by the present invention, as shown in fig. 3: after analyzing the redundant device status frame fed back by the second main control center host and obtaining the number of the redundant devices and the identifiers of the redundant devices, the method further comprises the following steps:
step S3, when the redundant device identifier does not include the first host identifier and the number of redundant devices does not satisfy the preset number of redundant devices, determining that the first host is faulty.
Specifically, under the condition that the redundant equipment identification does not include the host ID of the main control center of the gateway computer and the number of the redundant equipment is 1, the main control center of the gateway computer is judged to have a fault, and the condition that the communication link of the first main control center host is broken is detected, so that the reliability of the system is improved through double fault detection.
And step S4, executing an automatic master raising operation when the first master control center host fails.
The automatic master-up operation refers to the state that a gateway computer standby control center host enters an output control signal.
In practical application, when the main control center host of the gateway computer is in a normal working state, the main control center host of the gateway computer and the main control center host of the gateway computer run in parallel, but only the main control center host of the gateway computer outputs a control signal, the main control center host of the gateway computer does not output the control signal, and when the main control center host of the gateway computer breaks down, the main control center host of the gateway computer replaces the main control center host of the gateway computer to output the control signal, so that the normal operation of the system is ensured.
In another embodiment, referring to fig. 4, fig. 4 is a third schematic flow chart of the processing method for multiple redundancy states provided by the present invention, as shown in fig. 4: the executing of the automatic master-raising operation under the condition that the first master control center host fails specifically includes:
step S41, under the condition that the first main control center host computer has a fault, judging whether the communication link-breaking time of the first main control center host computer exceeds the internal redundancy link-breaking time;
specifically, the communication link-down duration refers to a duration that the first master control center host does not acquire the first master control center host.
In this step, in order to improve timeliness of redundant information interaction between a gateway computer and core devices such as an application server, the internal redundant link-down duration is limited in the present invention, and specifically, the internal redundant link-down duration is calculated in the following manner:
acquiring the master-up time of a first master control center host and the internal communication link-breaking time of the first master control center host; and calculating a difference value between the communication broken link time and the master-up time of the first standby control center host, and obtaining the internal redundant broken link time according to the difference value.
Specifically, the setting of the internal redundancy broken link time length should be smaller than the difference between the communication broken link time length and the master-up time length of the first master control center host, that is, the internal redundancy broken link time length may be any value within the range of the difference, which is not limited to this. The master-up duration of the first standby control center host is a flexibly variable value, for example, when the load of the first standby control center host is too large, the master-up duration of the first standby control center host is larger than the value of the master-up duration when the load of the first standby control center host is small.
And step S42, executing automatic master-raising operation when the communication broken link of the first main control center host exceeds the internal redundancy broken link time length.
When the main machine of the main control center of the gateway computer has network or software failure and can not work normally, based on the scheme, the main machine of the main control center of the application server only leaves the ID of the main machine of the standby control center of the gateway computer which is still working in the redundant equipment state frame which is reported to the main machine of the standby control center of the gateway computer after the main machine of the main control center of the application server starts to receive the state frame which is not reported by the main machine of the main control center of the gateway computer and waits for an internal redundant link-breaking time.
Meanwhile, the communication link-breaking time of the gateway computer main control center host and the gateway computer main control center host exceeds the internal redundancy link-breaking time, and the gateway computer main control center host can make sure that the gateway computer main control center host fails by combining the redundant equipment state frame reported by the application server main control center host. At the moment, the host of the gateway computer standby control center is immediately upgraded into a main control center to carry out control of output control signals.
In summary, from the time when the main control center host of the gateway computer stops operating to the time when the main control center host of the gateway computer is upgraded, the interruption time of the logic processing of the main control center host of the gateway computer is shorter than the communication link-down time in the ATS system. Before other devices in the ATS system judge that the communication with the main control center host of the gateway computer is interrupted, a new gateway computer standby control center host which is already upgraded in the ATS system can establish a path for information transmission with other software or systems in time, and the continuity of the information transmission is ensured.
In another embodiment, referring to fig. 5, fig. 5 is a fourth flowchart illustrating a processing method for multiple redundancy statuses provided by the present invention, as shown in fig. 5: before analyzing the redundant device status frame fed back by the second main control center host, the method further includes:
step S11, periodically sending a status frame to the second main control center host;
in the step, in order to avoid the situation of double masters of the control center, the master computer of the server main control center, the master computer of the server standby control center, the master computer of the gateway computer standby control center and the master computer of the gateway computer main control center periodically report respective state frames to the master computer of the opposite side, so that the reliability of the system is ensured by periodically reporting the state frames.
Step S12, receiving the first redundant device status frame or the second redundant device status frame fed back by the second host.
The redundant equipment identifier of the first redundant equipment state frame contains a first main control center host identifier, the number of the redundant equipment meets the preset redundant equipment number, and the redundant equipment identifier of the second redundant equipment state frame does not contain the first main control center host identifier and the number of the redundant equipment does not meet the preset redundant equipment number.
Specifically, a first redundant device status frame fed back by a second master control center host is received, wherein the second master control center host feeds back the first redundant device status frame when receiving the first status frame sent by the first master control center host and receiving a second status frame sent by the first master control center host within an interval internal redundant link-down duration; alternatively, the first and second electrodes may be,
and receiving a second redundant equipment state frame fed back by the second main control center host, wherein the second main control center host feeds back the second redundant equipment state frame when receiving the first state frame sent by the first main control center host and under the condition that the second state frame sent by the first main control center host is not received within the interval internal redundant link-breaking time.
The first redundant equipment state frame refers to an information frame for indicating that the gateway computer standby control center host is in a normal working state, and the second state frame refers to an information frame for indicating that the gateway computer main control center host is in an abnormal working state.
In other words, in the invention, when the main control center host of the gateway computer is in a normal working state, the number of the redundant devices in the first redundant device status frame fed back by the main control center host of the application server is 2, and the redundant device identifier includes the host ID of the main control center host of the gateway computer. When the main control center host of the gateway computer fails, the number of redundant devices in a second redundant device status frame fed back by the main control center host of the application server is 1, and the redundant device identifier does not include the main control center host ID of the gateway computer, so that whether the main control center host of the gateway computer is in a failure state or not is determined by the first redundant device status frame and the first redundant device status frame, and the normal operation of the system can be ensured.
In this step, after the application server main control center host receives the first status frame sent by the gateway computer standby control center host, the application server main control center host may also send a status frame request signal to the gateway computer main control center host to notify the gateway computer main control center host to send a second status frame to indicate that the gateway computer main control center host is in a normal operating state.
In addition, when the load of the host in the main control center of the gateway computer is too large, the speed of the host in the main control center of the gateway computer for processing signals may become slow, and thus the host in the main control center of the gateway computer may not be able to send the status frame in time. Therefore, the invention adopts setting an internal redundant broken link time length to verify whether the main machine of the main control center of the gateway computer fails. Therefore, the problem that the host of the standby control center of the gateway computer is misjudged due to the situation of the host of the main control center of the gateway computer, and enters the automatic master-raising mode to cause double masters of the control center is avoided, and the reliability of the system is improved.
In another embodiment, in order to improve timeliness of redundant information interaction between a gateway computer and core devices such as an application server, the present invention limits internal redundant link-breaking time, specifically, the internal redundant link-breaking time is calculated in the following manner:
acquiring the master-up time of a first master control center host and the internal communication link-breaking time of the first master control center host; and calculating a difference value between the communication broken link time and the master-up time of the first standby control center host, and obtaining the internal redundant broken link time according to the difference value.
Specifically, the setting of the internal redundancy broken link time length should be smaller than the difference between the communication broken link time length and the master-up time length of the first master control center host, that is, the internal redundancy broken link time length may be any value within the range of the difference, which is not limited to this. The master-up duration of the first standby control center host is a flexibly variable value, for example, when the load of the first standby control center host is too large, the master-up duration of the first standby control center host is larger than the value of the master-up duration when the load of the first standby control center host is small.
In summary, from the time when the main control center host of the gateway computer stops operating to the time when the main control center host of the gateway computer is upgraded, the interruption time of the logic processing of the main control center host of the gateway computer is shorter than the communication link-down time in the ATS system. Before other devices in the ATS system judge that the communication with the main control center host of the gateway computer is interrupted, a new gateway computer standby control center host which is already upgraded in the ATS system can establish a path for information transmission with other software or systems in time, and the continuity of the information transmission is ensured.
In another embodiment, in order to improve the timeliness of the interaction of the redundant information of the core devices such as the gateway and the application, the invention can also actively send the first state frame to the server standby control center host when the gateway computer standby control center host detects that the first main control center host has a communication broken link, thereby accelerating the speed of detecting the fault of the gateway computer standby control center host.
Specifically, when detecting that a communication link failure occurs in a first main control center host, sending a first status frame to the second main control center host; and receiving the redundant equipment state frame fed back by the second main control center host, and analyzing the redundant equipment state frame fed back by the second main control center host to obtain the number of the redundant equipment and the identification of each redundant equipment.
The first status frame refers to an information frame indicating that the gateway computer standby control center host is in a normal working state, where the first status frame may include a gateway computer standby control center host identifier, such as an interface ID, and the first status frame may further include a logic instruction, that is, after the application server main control center host receives the first status frame sent by the gateway computer standby control center host, the application server main control center host requests the gateway computer main control center host to send a second status frame, so as to verify whether the gateway computer main control center host is in a normal working state.
In addition, in another embodiment, the ATS system in the present invention is further provided with a redundant platform, and when detecting that a communication link failure occurs in the first host center, sending the first status frame to the second host center specifically includes:
