To illustrate the method of operation of the aircraft control system 10 of the present invention, referring to fig. 2, fig. 2 is a schematic flow chart of a first embodiment of a method for outputting data sources provided by an embodiment of the present invention. The main bodies for executing the method are a first workstation host 11, a second workstation host 12 and a third workstation host 13,. The specific flow of the output method of the data source may be as follows:
s21: the work station host acquires control information.
In the embodiment of the present invention, the first operating site host 11, the second operating site host 12, and the third operating site host 13 simultaneously obtain the control information. For example, a user sends control information through a mouse or a keyboard, and the first workstation host 11, the second workstation host 12, and the third workstation host 13 simultaneously acquire the control information.
S22: and the working position host and other working position hosts jointly select a target monitoring host, wherein the target monitoring host has the control right on the data source host.
In the embodiment of the present invention, information interaction is performed among the first workstation host 11, the second workstation host 12, and the third workstation host 13, so as to select a target monitoring host. The policy of the selected target monitoring host is set according to specific situations, which is not limited by the present invention.
In a specific embodiment, whether first preset information of a target monitoring host exists in the control information is judged, wherein the first preset information comprises at least one of an address and a name of the target monitoring host; if the first preset information exists, determining the target monitoring host according to the first preset information of the target monitoring host; and if not, determining the target monitoring host according to preset conditions. That is, if the user designates the target monitoring host through the control information, the monitoring host is determined according to the target monitoring host designated by the user, and if the user does not designate the target monitoring host, the target monitoring host is determined according to the preset condition.
S23, if the work position host is selected as the target monitoring host, controlling the data source host according to the control information so that the data source host outputs the corresponding data source according to the control information; if the target monitoring host is not selected, the target monitoring host is used as a monitoring target monitoring host to be selected, so that a new target monitoring host is selected together with other monitoring hosts to be selected when the current target monitoring host is determined to be in fault.
In the embodiment of the present invention, if the target monitoring host is selected, it indicates that the target monitoring host has the control right for the data source host 14, and the data source host 14 is controlled according to the control information, so that the data source host 14 outputs the corresponding data source according to the control information. If the host is selected as the target monitoring host, the host does not have the control right on the data source host 14 and is used as the monitoring target monitoring host of the monitoring host to be selected. When the target monitoring host is used as a monitoring host to be selected, a new target monitoring host is selected together with other monitoring hosts to be selected when the current target monitoring host is determined to be in fault. The new target monitoring host controls the data source host 14 according to the control information, so that the data source host 14 outputs the corresponding data source according to the control information. That is, the target host is monitored by the monitoring host to be selected, and when the target monitoring host fails, the target monitoring host is replaced in time, so that the data source host 14 is prevented from losing control.
To specifically describe the output method of the data source, please refer to fig. 3, and fig. 3 is a flowchart illustrating a second embodiment of the output method of the data source according to an embodiment of the present invention. The specific flow of the output method of the data source may be as follows:
s31: the work station host acquires control information.
In the embodiment of the present invention, the first work station host 11 obtains the control information. Specifically, the first station master 11, the second station master 12, and the third station master 13 simultaneously obtain the control information. For example, a user sends control information through a mouse or a keyboard, and the first workstation host 11, the second workstation host 12, and the third workstation host 13 simultaneously acquire the control information.
S32: and judging whether first preset information of the target monitoring host exists in the control information.
In the embodiment of the invention, after the control information is acquired, whether first preset information of the target monitoring host exists in the control information is judged. The first preset information comprises at least one of an address and a name of the target monitoring host. If the first preset information of the target monitoring host exists in the control information, indicating that the user designates the target monitoring host, the target monitoring host may be determined according to the first preset information of the target monitoring host, and then S33 is executed. If the first preset information of the target monitoring host does not exist in the control information, it indicates that the user does not designate the target monitoring host, and the target monitoring host needs to be determined according to the preset condition, and then S34 is executed. The preset conditions may be load, network speed, preset priority, and the like. On one hand, the user can determine the target monitoring host according to own habits, so that the humanization of the system is improved, and the user experience is improved; on the other hand, if the user does not specify the target monitoring host, the target monitoring host is selected according to the preset conditions, so that the target monitoring host is automatically determined, and the intelligence of the system is improved.
S33: and judging whether the self is matched with the first preset information.
In the embodiment of the invention, if the control information comprises first preset information of the target monitoring host, the target monitoring host is determined according to the first preset information of the target monitoring host. Specifically, it is determined whether the target monitoring host matches the first preset information, and if the target monitoring host matches the first preset information, the target monitoring host is selected as the target monitoring host, and then S351 is executed. If the host itself is not matched with the first preset information, it is determined that the host itself is not selected as the target monitoring host, and then S361 is executed. For example, the control information includes first preset information, and the first preset information is: a first work station host 11. That is, the user designates the first work station host 11 as the target monitoring host. At this time, the first station master 11, the second station master 12, and the third station master 13 respectively determine whether they match the first preset information. The first work station host 11 is matched with the first preset information, so that the first work station host 11 judges that the first work station host is the target monitoring host; the second working position host 12 and the third working position host 13 are not matched with the first preset information, so that the second working position host 12 and the third working position host 13 both judge that the second working position host is not a target monitoring host. And then the first working position host 11, the second working position host 12 and the third working position host 13 can select the target monitoring host as the first working position host 11.
S34: and judging whether the host is the least loaded work bit host of the at least two work bit hosts.
In the embodiment of the invention, if the control information does not include the first preset information of the target monitoring host, the target monitoring host is determined according to the preset condition. Specifically, it is determined whether the host is the lowest-load one of the at least two work level hosts, and if the host is the lowest-load one of the at least two work level hosts, it is determined that the host is selected as the target monitoring host, and then S351 is executed. If the host is not the least loaded one of the at least two work level hosts, it is determined that the host is not selected as the target monitoring host, and then S361 is executed. For example, the control information does not include the first preset information. I.e. the user only wants to change the source of the output data, but does not specify which job master is to be used for execution. At this time, information interaction is performed among the first workstation host 11, the second workstation host 12, and the third workstation host 13, and finally, the loads of the three workstation hosts are respectively: the number of the first working position host machine 11 is 10%, the number of the second working position host machine 12 is 20%, and the number of the third working position host machine 13 is 40%. The first work level master 11 determines that its own load is minimum, and therefore, the first work level master 11 determines that it is the target monitoring master, and the first work level master 11 performs S351. The second work station host 12 and the third work station host 13 both determine that they are not the work station host with the minimum load, and therefore, both the second work station host 12 and the third work station host 13 determine that they are not the target monitoring host, and then S361 is executed. And then the first working position host 11, the second working position host 12 and the third working position host 13 can select the target monitoring host as the first working position host 11. In other embodiments, it may also be determined whether the master is the master with the highest network speed or the highest preset priority of the at least two work level masters, and if so, S351 is executed; if not, S361 is executed, which is not limited by the present invention.
S351: and judging whether second preset information sent by the data source host is acquired within preset time.
In this embodiment of the present invention, the second preset information includes at least one of an address and a name of the data source host 14. The preset time may be 5s, 10s or other values, which may be set according to specific situations, and the present invention is not limited thereto. If the second preset information sent by the data source host 14 is obtained within the preset time, it indicates that the data source host 14 is online and can be controlled, S352 is executed, and if the second preset information sent by the data source host 14 is not obtained within the preset time, it indicates that the data source host 14 is not online and cannot be controlled, and a prompt message may be sent to prompt the user that the current data source host 14 is unavailable.
S352: and the target monitoring host controls the data source host so that the data source host outputs a corresponding data source according to the control information.
In the embodiment of the present invention, if the second preset information sent by the data source host 14 is obtained within the preset time, which indicates that the data source host 14 is online and can be controlled, the target monitoring host controls the data source host 14, so that the data source host 14 outputs the corresponding data source according to the control information.
S353: and ending the control data source host.
In the embodiment of the present invention, after the target monitoring host controls the data source host 14 so that the data source host 14 outputs the corresponding data source according to the control information, the control of the data source host 14 is terminated. That is, after the work position host is used as a target monitoring host to complete the remote control task, the control of the data source host 14 can be finished, and other tasks can be performed, so that the utilization rate of the work position host can be improved.
Further, after the data source host 14 is controlled as the target monitoring host to output the corresponding data source according to the control information, the data source host 14 may also send a task completion instruction to the other monitoring hosts to be selected, so that the other monitoring hosts to be selected end the task of monitoring the target monitoring host as the monitoring host to be selected, and thus the other monitoring hosts to be selected can perform other tasks, and the utilization rate of the whole system is improved.
S361: and judging whether the target monitoring host controls the data source host or not so that the data source host outputs a corresponding data source according to the control information.
In the embodiment of the present invention, when it is determined that the target monitoring host is not selected as the target monitoring host, it is determined whether the target monitoring host controls the data source host 14, so that the data source host 14 outputs the corresponding data source according to the control information. If the target monitoring host controls the data source host 14 so that the data source host 14 outputs the corresponding data source according to the control information, it indicates that the target monitoring host has no fault and can complete the task, and the monitoring host to be selected can end the task of monitoring the target monitoring host as the monitoring host to be selected, perform other tasks, and improve the utilization rate of the whole system. If the target monitoring host does not control the data source host 14, so that the data source host 14 outputs the corresponding data source according to the control information, it indicates that the target monitoring host fails to complete the task, and S362 is performed.
Specifically, whether a heartbeat packet sent by the target monitoring host is acquired within a preset time is judged, and if the heartbeat packet sent by the target monitoring host is acquired within the preset time, the target monitoring host is judged to control the data source host, so that the data source host outputs a corresponding data source according to the control information. And if the heartbeat packet sent by the target monitoring host is not acquired within the preset time, judging that the target monitoring host does not control the data source host, so that the data source host outputs the corresponding data source according to the control information. In other embodiments, whether the target monitoring host controls the data source host may also be determined in other manners, which is not limited in this application.
S362: and determining the fault of the current target monitoring host, and selecting a new target monitoring host together with other monitoring hosts to be selected.
In the embodiment of the present invention, if the target monitoring host does not control the data source host 14, so that the data source host 14 outputs the corresponding data source according to the control information, it is determined that the current target monitoring host fails, and a new target monitoring host is selected together with other monitoring hosts to be selected. Specifically, the target monitoring host may be determined according to preset conditions, where the preset conditions may be load, network speed, preset priority, and the like. The specific method is similar to S34, and the present invention is not described herein again. For example, the first station host 11, the second station host 12, and the third station host 13 select the target monitoring host as the first station host 11, and the second station host 12 and the third station host 13 monitor the first station host 11 for the monitoring host to be selected. When the first working position host 11 fails, the second working position host 12 and the third working position host 13 are used as monitoring hosts to be selected to jointly select a target monitoring host. That is, if the target monitoring host fails, the monitoring hosts to be selected jointly select a new target monitoring host to execute the control task, so as to avoid the data source host 14 losing control.
