Wherein:
the acquisition parameter description file 211 is mainly used for describing the communication protocol of the device set to be acquired and the state information to be acquired, and includes an acquisition device list, an acquisition device communication protocol list, an acquisition device communication address list, and an acquisition device parameter list. More specifically, for each level of communication components, the objects of the device description in the collection parameter description file are different: aiming at the subsystem-level communication components, equipment in the collected parameter file refers to single-machine equipment in each subsystem; aiming at the station-level communication assembly, collecting equipment in a parameter file refers to each subsystem; aiming at the station network level communication assembly, the equipment in the acquisition parameter file refers to each remote sensing satellite ground station in the station network.

As shown in fig. 3, the universal proxy unit 220 includes a status collecting module 221, a status formatting module 222, a status distributing module 223, and an instruction issuing module 224.
The main functions of the state acquisition module 221 are to establish communication with a device to be acquired according to the information of the acquisition parameter description file 211, actively acquire state information reported by the device, perform validity check on the acquired state information, and perform analysis according to an acquisition parameter list in the acquisition parameter description file 211 to obtain a device parameter state set. More specifically, the equipment is various professional equipment and IT equipment in a subsystem of the ground station in a subsystem-level communication component, and communication connection is established with the equipment mainly through TCP/IP communication and serial port communication; specifically pointing each subsystem level communication component in the ground station in the station level communication components, and establishing connection through a message queue; the station level communication components of each ground station are specially designated in the station level network communication components, and connection is established through a message queue. For this example, in a subsystem-level communication component: the state acquisition module 221 communicates with TCP/IP type of equipment, completes TCP/IP connection with the equipment directly, communicates with serial port type of equipment, uses SerialPort library provided by C #, acquires equipment state information at regular time and checks legality after establishing connection with the equipment, and finally analyzes legal state information to obtain equipment state set conforming to the interface; in the station-level communication assembly, a state acquisition module subscribes and reads the state information stored in the RockettMQ by a system-level communication assembly state distribution module in real time, and legality verification and analysis are carried out on the state information to obtain a device state set conforming to an interface; in the station network level communication assembly, a state acquisition module subscribes and reads the state information stored in the RocketMQ by the station level communication assembly state distribution module in real time, and legality verification and analysis are carried out on the state information to obtain a device state set conforming to an interface.

In this example, the Protobuf protocol is used to format the device parameter state set obtained according to the format description file 212, so that on one hand, the device parameter state set has better compatibility and can customize state data to be issued according to an interface in the format description file 212, and on the other hand, the device parameter state set has less data redundant information and can reduce bandwidth occupation to the maximum extent.
The main function of the status distribution module 223 is to establish communication connections with status data distribution destinations one by one according to the destination list, the destination communication protocol, and the destination communication address in the status data distribution description file 213, and to transmit the formatted status data to the respective data distribution destinations. More specifically, for each level of communication components, the state data distribution mode is greatly different: for the subsystem-level communication component, the status data distribution destination is a station-level communication component; for the station-level communication component, the state data distribution destination is the station-level network communication component, and here, the situation that the network bandwidth of each remote sensing satellite data receiving station in the station network and the station network center is limited needs to be considered, the state distribution module 223 compresses the data to be distributed according to the distribution data compression protocol defined by the state data distribution description file 213, and distributes the data to the station network center according to the distribution parameter priority specified by the state data distribution description file; for the station network level communication assembly, various application modules aiming at the rear end are distributed, and the application modules comprise rear-end applications such as state display, state data storage, fault diagnosis and health management. In this embodiment, each level of communication components uses a rockmq message middleware to perform data distribution, and the state distribution module of each level of communication components acquires the formatted state data output by the state formatting module 222 and publishes the formatted state data to a rockmq message queue. In addition, in the state distribution module 223 of the station-level communication component, the data formatted is compressed by using Zlib, and then is issued to the rocktmq message queue, so as to achieve the purpose of saving network bandwidth.

More specifically, for the subsystem-level communication component, the instruction issuing module 224 receives the instruction forwarded by the subsystem-level communication component, parses the instruction according to the instruction parameter list defined in the instruction parameter description file 214, and issues the instruction to the corresponding stand-alone devices one by one; for the station-level communication components, the instruction issuing module 224 receives the instruction forwarded by the station network center, and directly and transparently forwards the instruction to each subsystem-level communication component; for the station level communication components, the instruction issuing module 224 receives the instructions issued by each back-end application module, packages the instructions according to the instruction parameter list defined in the instruction parameter description file 214, and issues the instructions to the corresponding station level communication components. In this embodiment, a TCP/IP short connection is used to directly complete the command issue from the station level communication component to the station level communication component and from the station level communication component to the subsystem level communication component, and in the subsystem level communication component, a TCP/IP or serial protocol is automatically selected according to the type of the control device to complete the control of the device.
Preferably, as shown in fig. 4, besides each level of communication components, the system further includes an interactive interface unit 230, which is mainly used to provide a human-computer interactive interface, so as to implement centralized display of monitoring data and unified issuing of control data in the station network center. Wherein: the interactive interface unit 230 includes a status centralized display module 231 and an instruction management module 232:
the status centralized display module 231 displays the received device status data in real time, and monitors the device status in real time by combining with a preset device alarm threshold, and performs alarm prompt on the device with the parameter exceeding the alarm threshold. In this example, the state centralized display module 231 adopts a Winform framework, and the requirement of interface expandability can be met by dynamically adding a control. When an interface element needs to be added, an object entity can be created first, the attribute value, the event and the like of the current object entity are set, and then the object entity is added into the interface through an Add method of the container object Controls attribute.
The instruction management module 232 obtains the instruction parameters input by the user in real time, checks and packs the parameters, and then issues the parameters. In this example, the command management module 232 packages the commands according to the device control interface protocol, and performs MD5 verification to ensure that the commands are correctly and completely issued to each device.
