as shown in fig. 2 and 3, because the channels of the airborne signals are many (a coordination control panel, a line control operation interface, a data link operation interface, and an entity operation switch), the airborne short message device may receive communication instructions sent by a plurality of external control sources at the same time, and each control source can send the communication instructions through a corresponding physical interface, so as to trigger a processing program in the communication terminal to process, which may cause a delay in processing of important control information, thereby affecting the safe operation of the aircraft; the present application thus provides a method of device control for solving the above problems;
optionally, the control source mentioned herein may include at least one of an air interface wireless control source, an onboard device internal control source, an onboard human-computer interface control source, and an onboard automatic control interface source, where the receiving of the control signal sent by the control source may specifically be receiving of a control signal sent by one control source, or receiving of control signals sent by multiple control sources.

the priority configuration table mentioned here may specifically include a control source priority configuration table or a physical port priority configuration table, in which the priority of each control source or physical port is described, and the device may determine the priority of the control source or physical port to which the control signal belongs through the priority configuration table, and at the same time, only one table is in an active state, and the type of the priority configuration table may be determined by the operation mode configuration item;
alternatively, the core architecture of the priority configuration table may be as shown in the following table:
control source priority table
Numbering Control source type code Controlling source priority Extension bit
1 01 01 00
2 02 02 00
Physical interface priority table
Numbering Physical interface type code Physical interface priority Extension bit
1 01 01 00
2 02 02 00
The type code is used for representing the type of the control source or the physical interface, the priority is used for representing the priority of the corresponding control source or the physical interface, and the expansion bit is used for supplementing remark information and the like;

receiving a priority configuration table modification command;
judging whether the configuration mode of the priority configuration table is a dynamic configuration mode;
if so, executing a priority configuration table modification command to modify the priority configuration table;
if not, forbidding the modification.
The dynamic configuration mode mentioned here allows the priority configuration table to be modified while the device is operating normally; when the device is in the static configuration mode, the priority configuration table is not allowed to be modified when the device works normally, and only the priority configuration table is allowed to be modified when the device is in the maintenance mode or the abnormal working mode;

if yes, go to step S104;
when the priority of the control signal is higher than the priority of the current control source or the priority of the physical port, it indicates that the importance degree of the received control signal is higher than the currently executed control signal, and then the step S104 is entered to execute the control signal, so as to avoid the situation that the processing time of the important control information is delayed when the communication commands sent by the plurality of external control sources are received, and improve the safety of the aircraft operation.
Optionally, when the priority of the control signal is equal to or lower than the priority of the current control source or the priority of the physical port, the control signal may also be stored in the buffer queue, and after the current device is controlled, the control signal is extracted from the buffer queue in sequence and executed in sequence, so as to avoid the situation that the signal is not executed.
S104: the control signal is executed.
