Detailed Description
The present invention will be further described with reference to the accompanying drawings and detailed description, wherein it is to be understood that, on the premise of no conflict, the following embodiments or technical features may be arbitrarily combined to form new embodiments.
Example 1
The embodiment provides a command retry method, which is applied to an access control system, and can improve the final consistency of the authorization information of access control software and the information of an access control controller.
As shown in fig. 1 and 2, the command retry method of the present invention specifically includes the following steps:
step S1: acquiring a command with failed issuing, and time ordering the command with failed issuing;
step S2: and checking each command which fails to be issued in sequence, judging whether the command meets the retry condition, and re-issuing the command meeting the retry condition.
The method comprises the steps that a series of commands can be generated in the access control system through authorization information and hardware parameter information input by a software system, the generated commands are added to a to-be-issued list, and a command issuing thread sequentially issues the commands in the to-be-issued list to hardware equipment of the access control system, namely, issued to an access control controller to perform a series of verification work; when the issuing fails, the generated command which is not successfully issued is stored in a database, and a failure command buffer area is arranged in the database and used for storing the generated command which is not successfully issued.
In this embodiment, the failed issuing command is obtained through the message retry process, where the failed issuing command is mainly divided into a command that has been executed in the buffer and a command that failed issuing in the history record in the database. For executed commands, the executed commands can be directly abandoned, and for unexecuted commands with failed issuing, retry operation is needed.
The command with failed issuing can be obtained by means of timing inquiry, the command which is executed in the timing acquisition buffer and the command with failed issuing stored in the database are inquired and obtained at timing, so that timeliness of command acquisition is ensured.
The access controller can perform formatting operation before normal use, so that all data existing in the access controller are deleted, and reset to an initial value for a new user to use; therefore, after obtaining the command with failed issuing, the command with failed issuing needs to be subjected to formatting judgment, so as to judge whether the command with failed issuing is a formatting command, if so, the command needs to be abandoned.
Because the formatted command has the unique command type, the embodiment obtains whether the command is the formatted command by judging the command type of the command, and gives up the formatted command after judging that the command which is failed to be issued is the formatted command and other commands with the same targets are arranged behind the command, changes the state of the formatted command into giving up and moves the state of the formatted command to an executed table; if the failed command is not the formatted command, the retry operation is continued.
Meanwhile, as different access control clients may operate the same authorization information, the same command corresponding to different devices is generated, after the formatted command is judged, whether the command which fails to be issued conflicts with other commands is also needed to be judged, namely whether the command which fails to be issued has the same Dataid is judged, if so, the commands of the same Dataid are combined to reduce the command transmission quantity; if not, the retry operation is continued.
After the above processing, the formatted commands are deleted, and after the same commands are combined, the retry condition is determined for the remaining commands that have not been issued successfully, in this embodiment, it is determined whether the commands satisfy the retry condition, and the following five conditions are required to be determined, where the five conditions are respectively:
1. judging whether the command is expired; since the expiration time of issuing the command is defaulted to 24 hours when the system configures the command, when the command deadline is judged, whether the issuing time interval of the command exceeds 24 hours or not is judged according to the issuing time of the command, if yes, the command is expired, if not, the command is not expired, and the command is still in a valid state.
2. Judging whether the command reaches the preset retry interval time; the preset retry interval in this embodiment is calculated according to the interval time of the quadratic curve, such as the first interval of 5 seconds, the second timeInterval 2 2 *5 seconds, and so on.
3. Judging whether the command is a command for emptying the device or has the same identification field as other commands; judging whether the command is a command for emptying the device, namely, judging whether the current command is a formatting command again, if so, carrying out formatting operation on the device corresponding to the command to obtain the emptied device, and discarding the command at the moment; and judging whether the command has the same identification field as other commands, namely, judging whether the command has the same command as the Dataid of the command again, and if so, merging the commands with the same identification field.
4. And judging whether the command is in a state to be retried.
5. Judging whether the target equipment is on-line or not, namely judging whether an access controller is on-line or not; the method for judging whether the target equipment is online can judge whether the target equipment makes a corresponding response when receiving the heartbeat packet in a heartbeat packet mode, if the corresponding response is made, the target equipment is online, and if the response is not obtained for a plurality of times, the target equipment is judged to be not online.
If the command is judged to be an effective command, the command reaches the retry interval time, the command is different from the command of the emptying device, the identification field which is not the same as the other commands is not present, the target device corresponding to the command is in an on-line state, and the command is in a state to be retried, the retry condition is met; if any condition is not met, the retry operation is abandoned, and the record of the command with failed issuing in the database is reserved.
In this embodiment, adding a command meeting a retry condition to a message queue, and sequentially issuing the commands in the message queue according to the queue order of the message queue; before issuing the command in the message queue, the command can be packaged according to the equipment type and the service type, and the packaged command is issued uniformly, so that the command transmission times are reduced; at the same time, the command state is updated to be the issuing state, and the command state is fed back and displayed.
In the embodiment, the command with successful retry is issued, and the issued command with successful retry is moved into the issued table, so that software and hardware data are kept consistent as much as possible; commands that do not meet retry conditions or that give up retries are still recorded in the database to repeat the retry process described above to achieve a retry operation of the command again, but commands that fail to retry a preset number of times are discarded to balance system performance.
