The collection parameter description file 211 is mainly used to describe the communication protocol of the device set to be collected and the status information to be collected, and includes a collection device list, a collection device communication protocol list, a collection device communication address list, and a collection device parameter list. More specifically, for communication components at all levels, the objects described in the acquisition parameter description file are different: for sub-system-level communication components, the devices in the acquisition parameter file refer to stand-alone devices in each sub-system; for station-level communication Component, the equipment in the acquisition parameter file refers to each sub-system; for the station network-level communication component, the equipment in the acquisition parameter file refers to each remote sensing satellite ground station in the station network.

In this embodiment, the communication components at all levels use the RockerMQ message middleware for data distribution, and the state distribution module of the communication components at all levels obtains the formatted state data output by the state formatting module 222 and publishes it to the RocketMQ message queue . In addition, in the state distribution module 223 of the station-level communication component, Zlib is used to compress the formatted data first, and then publish it to the RocketMQ message queue, so as to save network bandwidth.

The command to be sent is packaged according to the command parameter list defined in the command parameter description file 214, and sent to the corresponding station-level communication component. In this embodiment, the TCP/IP short connection is used to directly issue instructions from the station-level communication component to the station-level communication component and from the station-level communication component to the sub-system-level communication component. In the sub-system-level communication component, according to the control device Type, automatically select TCP/IP or serial port protocol to complete the control of the device.

In this example, the centralized state display module 231 adopts the Winform framework, which can satisfy the requirement of interface expansion by dynamically adding controls. When you need to add interface elements, you can first create an object entity, set the property values and events of the current object entity, etc., and then add it to the interface through the Add method of the Controls property of the container object.

The instruction management module 232 acquires the instruction parameters input by the user in real time, verifies and packs the parameters, and then issues them. In this example, the instruction management module 232 packages the instructions according to the device control interface protocol, and performs MD5 verification to ensure that the instructions are correctly and completely delivered to each device.
