Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The embodiment of the invention monitors whether a first coding instruction exists or not during starting, sets a local number based on the first coding instruction, generates a second coding instruction according to the local number after the starting is finished, and is used for equipment coding of a subsequently started service terminal, so that all service terminals in a local area network form an equipment chain, the service terminal of the next node is used as an associated backup terminal, when an abnormal event is detected, the service request and the service data of the service request can be forwarded to the associated backup terminal for continuous response, the technology of abnormal response is solved, when the terminal equipment is abnormal, a user needs to re-respond to the operated service flow, the success rate and the processing efficiency of the service response are reduced, and the problem of service handling time of the user is prolonged.
In the embodiment of the invention, the execution subject of the process is the terminal equipment. The terminal devices include but are not limited to: and devices such as servers, computers, smart phones and tablet computers capable of executing abnormal response operations. Particularly, the terminal device may be a terminal placed in a service handling website, and a user may perform service handling through the terminal in the service handling website, thereby achieving the purpose of self-service handling. Fig. 1 shows a flowchart of an implementation of the method for exception response provided by the first embodiment of the present invention, which is detailed as follows:
in S101, if an equipment starting instruction is received, executing an equipment starting process, and detecting whether a first coding instruction is received within a preset starting time threshold value; the first coding instruction carries a device number of a first service terminal sending the coding instruction.
In this embodiment, a plurality of terminal devices for users to self-service services may be configured in the service handling website, and an administrator may send a device start instruction to each terminal device at a preset start time interval, that is, only one terminal device may be sent a device start instruction at the same time. Specifically, the administrator can send a device start instruction to the terminal device by clicking an open button on the body of the terminal device. Optionally, after the terminal device executes the shutdown operation, a monitoring thread of the device start instruction is reserved for detecting whether the upper computer server sends the device start instruction to the local terminal, and except for the monitoring thread, other processes and programs are all in a closed state. Through the mode, the terminal equipment can reduce energy consumption in the closed state, can also respond to the remote start instruction of the upper computer in real time, and improves the operation efficiency of the terminal equipment.
In this embodiment, in the process of executing the start-up procedure, the terminal device may first start up an encoding instruction monitoring thread to receive the first encoding instruction sent by the other started service terminals. Specifically, the starting process refers to that the terminal device loads a system file, constructs a service system of the service terminal, and starts a plurality of threads to run a preset application program. It should be noted that the encoding instruction monitoring thread is independent of the start-up process, that is, one thread that is parallel to the start-up thread in the main process of the terminal device, and performs the monitoring operation of the encoding instruction during the start-up operation.
In this embodiment, the service terminal in the lan includes a terminal device, and after the start is completed and the device code of the service terminal is configured, the service terminal broadcasts a first coding instruction in the lan, so that the service terminal that is started later can configure the local device code according to the first coding instruction. Therefore, after the terminal device provided in this embodiment is started, if the first encoding instruction of the first service terminal is received, the relevant operation of S102 is executed; otherwise, if the first coding instruction of the first service terminal is not received, the first coding instruction is continuously monitored within the preset starting time threshold.
Optionally, if the first coding instruction is received within a preset starting time threshold, a coding configuration request may be sent to the terminal of the administrator, so that the administrator performs a manual local number setting operation on the terminal device.
In S102, if the first encoding instruction is received within the starting time threshold, a local number is set based on the device number.
In this embodiment, when the terminal device receives the first coding instruction sent by the first service terminal within the start time threshold, it may identify that the first service terminal is an upper node of the terminal device, extract the device number of the first service terminal described in the first coding instruction, and set the local number based on the device code, optionally, the terminal device may add 1 on the basis of the device number, for example, if the device number of the first service terminal is 3, the local number of the terminal device is 4.
Optionally, after the terminal device completes configuration of the local number, a communication link with the first service terminal is established, and a coding completion instruction is returned to the first service terminal, and after the first service terminal receives the coding completion instruction returned by the terminal device, the terminal device is identified as an associated backup terminal of the first service terminal, and when the first service terminal sends an exception, all local currently-processed service requests may be responded to by the terminal device.
Preferably, after the terminal device establishes the communication link between the first service terminals, the first service terminal sends heartbeat packets to the terminal device at preset heartbeat time intervals, so that the validity of the communication link can be maintained, on the other hand, the terminal device can also monitor whether an abnormal event occurs at the first service terminal, and when an abnormal event occurs, the abnormal service request currently processed by the first service terminal and the service data associated with the service request can be retrieved from the first service terminal through the communication link.
In S103, a second coding instruction is generated according to the local number, and the second coding instruction is broadcasted in the local area network, so that any second service terminal executing the start process sets the device number of the second service terminal based on the second coding instruction.
In this embodiment, after the terminal device configures the local number, a second coding instruction is generated, where the second coding instruction carries the local number of the terminal device, and the second coding instruction is broadcast in the local area network, so that a subsequently started second service terminal can monitor the second coding instruction in a starting process, and the device number of the second service terminal is configured based on the local number in the second coding instruction. Therefore, through the operations of S101 to S103, all service terminals in the local area network, including the terminal device provided in this embodiment, may configure a local number according to the device number of the service terminal started previously, and then generate a second coding instruction according to the local number, so that the service terminal started later may set its own device number on the basis of the local number, thereby forming a device chain.
For example, the device number of the service terminal a is 1, after the local number configuration of the service terminal a is completed, a first coding instruction is generated, at this time, the service terminal B enters a start process, because only one service terminal is in the start process at the same time in the local area network, at this time, only the service terminal B receives the first coding instruction sent by the service terminal a, thereby configuring the device number of the service terminal B to be 2, and then the service terminal B also generates a second coding instruction, at this time, the service terminal C enters the start process, and sets the device number of the service terminal C based on the second coding instruction to be 3, and so on.
It should be noted that, in the process of configuring the local number, the terminal device may still be in a start-up flow, that is, loading the service system and starting the application program, in this case, after receiving the first encoding instruction, the terminal device may modify the local EPROM, that is, the storage unit for storing the local number, through the encoding instruction monitoring thread, where the storage unit is a fixed value in the process of this start-up, and will not be changed until the next time the terminal device is started up or logs out of the local area network abnormally. Similarly, after the terminal device finishes setting the local code, the terminal device may still generate the second coding instruction through the coding instruction monitoring thread and execute the broadcast operation, and meanwhile, the terminal device may still be in the starting process, or may have already executed the starting process, and receive the service request initiated by the user, that is, the starting process and the setting process of the local code are independent from each other.
In S104, if a coding completion instruction returned by the second service terminal based on the second coding instruction is received within an effective waiting period, the second service terminal is identified as an associated backup terminal.
In this embodiment, after the second service terminal device receives the second encoding instruction sent by the terminal device, the device number of the second service terminal device may be configured through the second encoding instruction. After the device number has been configured, in order to avoid that the terminal device continues to broadcast the second coding instruction, thereby repeatedly coding the other service terminals except the second service terminal, the second service terminal generates a coding completion instruction based on the second coding instruction, and returns the coding completion instruction to the terminal device. When the terminal equipment receives the coding completion instruction, the second service terminal can be identified as the next node of the terminal equipment and used as the associated backup terminal, and when an abnormal condition occurs, the local service request can be delivered to the second service terminal for subsequent response, so that the conditions of data loss of a user and service re-handling are avoided.
Specifically, the terminal device is configured with an effective waiting period, when the terminal device broadcasts the second encoding instruction for the first time, the waiting timer is started, and if the count value of the waiting timer is smaller than the effective waiting period and the encoding completion instruction is received, the relevant operation of S104 is executed; on the contrary, if the count value of the waiting timer is greater than or equal to the effective waiting period and the coding completion instruction is not received, it may be determined that the terminal device in the local area network is the last started service terminal, and the service terminal of the first node in the local area network may be identified as the associated backup terminal, or of course, the service terminal of the previous node, that is, the first service terminal may also be identified as the associated backup terminal.
In S105, if the local current time meets a preset abnormal triggering condition, sending each currently processed service request and service data of the service request to the associated backup terminal, so that the associated backup terminal responds to each service request based on the service data.
In this embodiment, the terminal device is provided with an abnormal triggering condition, and the terminal device monitors an operation parameter of the local terminal and determines whether the current time meets a preset abnormal triggering condition. For example, the abnormal triggering condition may be that the terminal electric quantity is lower than 5%, based on which, the terminal device may obtain the electric quantity value of the terminal device in a preset abnormal monitoring period, and if the obtained electric quantity value at the current time is lower than 5%, identify that the current time meets the preset abnormal triggering condition, and execute the relevant operation of S105. Of course, the terminal device may determine that an abnormal event occurs locally in a self-checking manner, or in a monitoring manner of other devices. For example, as described above, the terminal device may send a heartbeat packet to the associated backup terminal at a preset heartbeat cycle, so as to maintain the validity of the communication link between the terminal device and the associated backup terminal. If the associated backup terminal does not receive the heartbeat data packet sent by the terminal device in the heartbeat cycle, the terminal device may be in a down state, and it is not possible to detect that the current time meets the abnormal triggering condition and send the heartbeat data packet, at this time, the associated backup terminal may send an abnormal triggering instruction to the terminal device, and at this time, the terminal device may also execute the relevant operation of S105.
In this embodiment, after the terminal device is started, the terminal device may receive a service request initiated by a user, and generate corresponding service data based on a service operation of the user. When the terminal device detects that the current time meets the preset abnormal triggering condition, all the service requests which are not completed currently and the service data associated with each service request are sent to the associated backup terminal in a unified mode, the associated backup terminal can continuously respond to the service requests according to the service data, a user does not need to initiate the service requests again, the operated process is executed again, and the service handling progress is reserved.
It can be seen from the above that, in the method for responding to an exception provided in the embodiment of the present invention, when the method is started, whether a first coding instruction exists is monitored, a local number is set based on the first coding instruction, and after the method is started, a second coding instruction is generated according to the local number for device coding of a subsequently started service terminal, so that all service terminals in a local area network form a device chain, and a service terminal of a next node is used as an associated backup terminal. On the other hand, the mode does not need to introduce a server, and the service terminals in the formed equipment chain form a mutual backup relationship, so that the manufacturing cost of the service response system is reduced, and the overall robustness of the system is also improved.
Fig. 2 is a flowchart illustrating a specific implementation of a method for responding to an exception according to a second embodiment of the present invention. Referring to fig. 2, with respect to the embodiment shown in fig. 1, the method for responding to an anomaly provided in this embodiment further includes: s201 to S205 are specifically detailed as follows:
further, as another embodiment of the present invention, after setting a local number based on the device number if the first encoding instruction is received within the starting time threshold, the method further includes:
in S201, all service requests and service data sent by the first service terminal having an abnormal event are received, and the number of the service requests of the first service terminal is counted.
In this embodiment, when each service terminal is abnormal in the device chain, the service request and the service data are all transferred to the next node for exception handling, that is, the terminal device provided in this embodiment is also an associated backup node of the first service terminal, so that when an exception event occurs in the first service terminal, the currently processed service request and the corresponding service data can be sent to the terminal device. The terminal device may serve as a processing middleware and forward the service request to each service terminal based on the number of the service requests and the load condition of each service terminal in a normal state in the local area network. Based on this, after receiving the service request and the service data, the terminal device counts the total number of the service requests sent by the first service terminal.
It should be noted that, since the terminal device is the associated backup terminal of the first service terminal, after receiving the service request and the service data sent by the terminal device, the associated backup terminal of the terminal device in the first embodiment may also respond in the manner of S201 to S205, which is not described herein again.
In S202, the operation parameters and the service request number of each service terminal in the normal state in the local area network at the current time are obtained.
In this embodiment, in order to implement load balancing and avoid the situation that all service requests are handled locally to cause overload, the terminal device needs to determine the load situation of each service terminal in a normal state in the local area network, so as to determine the forwarding number of each service terminal. Based on this, the terminal device broadcasts in the local area network, so that each service terminal in a normal state reports the operation parameters at the current time and the number of service requests processed by the services processed normally.
In this embodiment, the operating parameters include, but are not limited to: and parameters related to the operation of the service response terminal, such as operation rate, network bandwidth, idle thread number, storage resources and the like. The service response capability of the service terminal can be determined through the operation parameter, and if the operation parameter is larger, the response efficiency of the service terminal is higher. The load pressure of the service terminal at the current moment can be determined through the service request number processed at the current moment, preferably, the terminal device records the maximum response number of each service terminal, after the terminal device obtains the service request number of each service response terminal, the load proportion of each service terminal can be determined according to the service request number and the corresponding maximum response number, and the load parameters can be normalized through the method, so that the accuracy of the subsequent calculation processing priority can be improved.
In S203, the processing priority of each service terminal in the normal state is calculated based on the operation parameter and the service request number.
In this embodiment, after acquiring the operation parameters and the service request number of each service terminal in the normal state, the terminal device may import the two parameters into the priority selection model, so as to calculate and obtain the processing priority of each service terminal in the normal state, wherein if the value of the operation parameter of the service terminal is larger, it indicates that the operation efficiency of the service terminal is higher, and the value of the corresponding priority is larger; on the other hand, the smaller the number of service requests, the smaller the load pressure of the service terminal, and the larger the number of service requests that can be received, the larger the corresponding priority value.
It should be noted that the numerical value of the priority is used to indicate the task processing capability of the service terminal, that is, the larger the numerical value of the priority is, the stronger the task processing capability is, and a larger number of service requests can be forwarded; on the contrary, if the numerical value of the priority is smaller, it indicates that the task processing capability of the device is poor, the corresponding forwarding number is smaller, and even no forwarding is performed. When calculating each processing priority, the terminal device may also count local operating parameters and the number of service requests, thereby determining the number of service requests that need to be processed locally.
Alternatively, the processing priority may be calculated by the following formula:
wherein, PRI (j) is the processing priority of the jth service terminal in normal state; RunPrmerjThe operation parameters of the jth service terminal in the normal state are obtained; requustjThe service request number of the jth service terminal in the normal state; m is the number of the service terminals in the normal state; alpha is a preset coefficient.
In S204, respectively importing each processing priority and the number into a forwarding number calculation model, and determining the forwarding number of each normal service terminal; the forwarding number calculation model specifically comprises:
wherein, replynum (j) is the forwarding number of the jth service terminal in the normal state; PROjThe priority of the jth service terminal in the normal state; requstuckum is the number; n is the same asThe number of terminals of the service terminal in the normal state.
In this embodiment, after determining the processing priority value of each service response terminal, the terminal device may import the priority value and the counted number of service requests sent by the first service terminal into the forwarding number conversion model, and if the priority value is larger, the number of service requests to be forwarded is larger; conversely, if the value of the priority is smaller, the number of service requests to be forwarded is smaller. Preferably, after obtaining the calculation result, the terminal device performs a rounding operation on the calculation result, and takes a rounded value as the forwarding number.
In S205, based on the forwarding number, the service request and the service data are respectively forwarded to each of the service terminals in the normal state.
In this embodiment, after determining the forwarding number of each service terminal, the terminal device may forward the service requests of the corresponding number and the service data of each service request to the service terminal, and respond to the service request based on the service data through the forwarded service terminal.
In the embodiment of the invention, the processing priority of each service terminal is determined by acquiring the operation parameters and the service request number of each service terminal, and the forwarding number of each service terminal is determined based on the processing priority, so that when an abnormal condition occurs, the service request of the abnormal terminal can be subjected to load distribution through the associated backup node, the load balance is realized, and the process condition is avoided.
Fig. 3 is a flowchart illustrating a specific implementation of a method for responding to an exception according to a third embodiment of the present invention. Referring to fig. 3, with respect to the embodiment described in fig. 1, in the method for responding to an exception provided in this embodiment, if the local current time meets a preset exception triggering condition, after sending each service request currently processed and service data of the service request to the associated backup terminal, the method further includes: s301 to S302 are described in detail as follows:
in S301, if the abnormal repair completion instruction is received, broadcasting a link entry request in the local area network, so that a third service terminal with a maximum device number in the local area network feeds back a third coding instruction; the third encoding instruction includes a device number of the third service terminal.
In this embodiment, when detecting that the current time meets the abnormal triggering condition, the terminal device forwards the service request and the service data to the associated backup terminal, and at this time, the terminal device logs out the device chain. After the terminal device is abnormally repaired and needs to join the device chain again, a chain entering request can be broadcasted in the local area network to execute the chain entering operation.
Optionally, in this embodiment, when detecting that the current time meets the abnormal triggering condition, the terminal device broadcasts a device log-out instruction in the local area network, where the device log-out instruction carries a local number of the terminal device, and if any service terminal in the local area network detects that the device number of the service terminal is greater than the local number of the device log-out instruction, the device number of the service terminal is adjusted, so that when the service terminal is abnormal and logs out of the device chain, each service terminal in the device chain can still maintain a mutual backup relationship, and the ordering among the device numbers is continuous.
In this embodiment, since each service terminal in this embodiment may establish a connection with the associated backup device, the device number of the associated backup device may be obtained through the communication link, and if it is detected that the local number is smaller than the device number of the associated backup device, it may be determined that the service terminal is not located at the tail node of the device chain, that is, the value of the device number of the service terminal is not the maximum, and the third encoding instruction is not generated; on the contrary, if the local number is detected to be greater than the device number of the associated backup terminal, it can be determined that the local number is at the tail node of the device chain, that is, the numerical value of the device number of the local number is the largest, a third coding instruction is generated and sent to the terminal device, and the terminal device is identified as the associated backup terminal of the local number.
In S302, the third encoding instruction is received, a local number is set based on the device number of the third service terminal, the second encoding instruction generated according to the local number is returned to be executed, and the second encoding instruction is broadcasted in the local area network.
In this embodiment, after receiving the third encoding instruction, the terminal device reconfigures its local number according to the device number carried in the third encoding instruction, and the operation is completely the same as the operation of S102, which is not described herein again.
In the embodiment of the invention, the local number of the device chain is configured based on the third coding instruction with the largest device number by broadcasting the link entering request, so that the local number is automatically added to the tail of the device chain after the abnormity is repaired, the backup relation of the normally running service terminal is not influenced, and the link entering efficiency is improved.
Fig. 4 is a flowchart illustrating a specific implementation of a method for responding to an exception according to a fourth embodiment of the present invention. Referring to fig. 4, with respect to the embodiment shown in fig. 1 to fig. 3, after the generating a second encoding instruction according to the local number and broadcasting and sending the second encoding instruction in the local area network, the method for responding to an exception according to this embodiment further includes: s401 to S402 are specifically described as follows:
in S401, if the encoding completion instruction is not received within the valid waiting period, the device number of each service terminal in the local area network is obtained.
In this embodiment, the terminal device broadcasts the second encoding instruction in the local area network, and when all the service terminals in the local area network have completed encoding, there is a case where no service terminal returns an encoding completion instruction to the terminal device. Based on this, the terminal device detects whether a coding completion instruction is received in an effective waiting period, if the coding completion instruction returned by any service terminal is not received even if the effective waiting period is exceeded, the terminal device indicates that the terminal device is located at the tail node of the device chain, the number of each service terminal device in the local area network is inquired, and the first node is selected as the associated backup terminal of the terminal device, so that a device ring is formed.
In S402, the service terminal whose device number is the preset initial number value is identified as an associated backup terminal.
In this embodiment, the terminal device may identify the service terminal whose device number is the initial coding value as the associated backup terminal, for example, the initial coding value is 1, that is, when the first service terminal is started in the local area network, the terminal device may set the device number of the terminal device to 1, and therefore, the terminal device may identify the service terminal whose device number is 1 as the associated backup terminal according to the obtained device number of each service terminal. Of course, if the initial value of the code of the lan is 2, the service terminal with the device number 2 may also be selected as the associated backup terminal.
