Claims

1. A port task processing method of a satellite measurement, operation and control system is characterized by comprising the following steps:

the satellite measurement, operation and control system obtains a plurality of port tasks from a plurality of clients through a built-in port scanner, wherein the clients comprise clients and satellite terminals;

a port scheduler in the satellite measurement, operation and control system respectively determines corresponding timing time for the plurality of port tasks;

when the timing time is up, distributing the port task corresponding to the timing time to a task executor;

and the client corresponding to the port task is connected with the task executor so as to process the port task.

2. The method of claim 1, wherein the satellite instrumentation and control system obtains a plurality of port tasks from a plurality of clients via a built-in port scanner, comprising:

the satellite measurement, operation and control system establishes network socket connection with the plurality of clients through the built-in port scanner;

binding based on the network socket connection and the ports and IPs of the plurality of clients;

and monitoring the bound ports to acquire a plurality of port tasks.

3. The method of claim 2, wherein snooping the bound ports for obtaining a plurality of port tasks comprises:

acquiring port task processing requests by a plurality of clients;

establishing a connection with the plurality of clients based on the port task processing request;

and acquiring a plurality of port tasks of the plurality of clients based on the connection.

4. The method of claim 3, wherein obtaining the plurality of port tasks for the plurality of clients based on connections comprises:

providing a port task setting page for the plurality of clients;

and acquiring the port task based on the port task setting page.

5. The method of claim 4, wherein a port scheduler in the satellite measurement, operation and control system determines respective timing times for the plurality of port tasks, further comprising:

and setting the timing time corresponding to the plurality of port tasks by the port task setting page.

6. The method of claim 1, wherein the connection between the client corresponding to the port task and the task executor is established to process the port task, and the method comprises:

establishing network socket connection between the client corresponding to the port task and the executor;

connecting the client to operate in the processing process of the port task based on the network socket;

and the task executor responds to the client operation to process the port task.

7. The method of claim 1, further comprising:

and after the port task is processed, interrupting the connection and informing the port scheduler.

8. A port task processing device of a satellite measurement, operation and control system is characterized by comprising:

the scanning module is used for acquiring a plurality of port tasks by a plurality of clients through the built-in port scanner, wherein the clients comprise clients and satellite terminals;

the scheduling module is used for respectively determining corresponding timing time for the plurality of port tasks;

the distribution module is used for distributing the port task corresponding to the timing time to the task executor when the timing time is up;

the connection module is used for establishing connection between the client corresponding to the port task and the task executor so as to process the port task;

and the interrupt module is used for interrupting the connection and informing the port scheduler after the port task is processed.

9. An electronic device, comprising:

one or more processors;

storage means for storing one or more programs;

when executed by the one or more processors, cause the one or more processors to implement the method of any one of claims 1-7.

10. A computer-readable medium, on which a computer program is stored, which, when being executed by a processor, carries out the method according to any one of claims 1-7.
