Detailed Description
The present invention will be described in further detail below with reference to the accompanying drawings.
The invention relates to a design method for single-machine plug and play of a satellite control system, which comprises the following steps:
(1) the various single machines used by the satellite control system are designed according to a unified standard, and a unique identifier is defined for each single machine, wherein the single machines comprise a sensor single machine (such as a gyroscope and a star sensor) and an actuator single machine (such as a flywheel).
The format of the unique identifier is as follows: IdSig1+ IdSig2+ IdSig3+ IdSig 4;
wherein IdSig1 is the administrative region code of the production unit; IdSig2 is the unit or company code of the production unit; IdSig3 is a stand-alone product type code; IdSig4 is the unit or in-company factory number for a stand-alone product.
This unique identifier is the basis for the autonomous identification of the subsequent units, which are physically connected to the host computer through a bus switch, as shown in fig. 1, which is a schematic diagram of an attitude control system, and which are connected to the satellite control system host computer using bus interfaces (e.g., 1553, 422, etc.).
(2) The satellite control system host machine uses an autonomous identification method to automatically identify and assign the node address to the newly replaced stand-alone or the newly added stand-alone.
The autonomous identification method comprises two methods:
the first is a host-active method: when the satellite control system and the original stand-alone are in a power-off state, a newly replaced stand-alone or a newly added stand-alone is added, the host continuously sends broadcast frame information after the host and the stand-alone are powered on, the stand-alone preferentially responds to the broadcast frame after being powered on and gives a unique identifier of the host, and the host allocates node addresses according to product type codes contained in the unique identifier to finish autonomous identification.
Another approach is host-passive: when the satellite control system and all the original single machines are identified and newly replaced single machines or newly added single machines are added (the host can not actively sense the newly replaced or added single machines), the single machines are electrified and then autonomously send identification application frames to the host, and the host distributes node addresses for the new single machines after receiving the application frames to complete autonomous identification.
Through the two modes, the satellite control system can realize the autonomous identification of the stand-alone when the stand-alone is added or replaced in the power-off or power-on state.
FIG. 2 is the autonomous identification process of the satellite control system host and the stand-alone units, wherein when the stand-alone units are not powered on, the host links the newly powered stand-alone units in time by continuously transmitting broadcast frame information. After the satellite control system and all the original single machines are identified, when a new single machine is added, the single machine independently sends an identification application frame, and the host machine completes the independent identification of the new single machine. By the two modes, the autonomous identification of the satellite control system when the stand-alone is added or replaced is realized.
(3) The satellite control system uses an autonomous communication method to realize autonomous communication between the host and the single machine.
The autonomous communication method defines standard communication format and content including communication command form, byte length, type, resolution and other attributes, completes the communication definition of each kind of single machine and completes autonomous communication and application after autonomous identification.
As shown in FIG. 3, the autonomous communication flow between the host and the single machine is as follows:
the host computer and the single computer adopt master-slave communication, the host computer is a data communication initiator, and the single computer is a data provider;
the host sends a data request to the single machine;
after receiving the request of the host computer, the single computer measures the data and sends the data to the host computer;
the host machine carries out check code verification on the received measurement data, if the check code is correct, the host machine analyzes the measurement data according to an agreed standard format and carries out other processing according to the pre-design; if the check code is incorrect, the method is ended.
Each single product type is corresponding to a standard communication format and communication content, and the communication content is a minimum set for describing basic functions of the single product. Taking a type of a single-machine product such as a gyroscope as an example, the communication data content is as follows: Data-B1 + (X) + SumChrk
B1: the top comprises the number of the gauge heads;
x is determined by the number of heads determined by B1, and the specific composition of X is (C1+ C2+ C3) B1;
c1, measuring the angular speed by a gauge head, and shaping the four bytes unsigned;
c2, gyro temperature, double-byte unsigned integer data;
c3, light source state, single byte unsigned integer data;
SumChrk: the check word is used for ensuring that the transmission data is normal;
fig. 3 shows the autonomous communication process between the host and the single machine, still taking the gyroscope as an example, the autonomous communication steps are divided into 3 steps.
1) The host sends out a data request command: command header + command (e.g., 0x1A indicates that gyro measurement data is requested).
2) And after receiving the request instruction, the gyro single machine sends self-acquired data: information frame header + Data; (the definition of Data is given above by way of example).
3) After receiving the information, the host computer analyzes the information by adopting a standard format to obtain the single machine information. Because the communication content of the gyroscope is agreed according to the basic characteristics provided by the single machine such as the gyroscope, the information provided by various single machines is consistent, so that the single machines of different manufacturers and different specifications can independently communicate, and the independent data interaction between the host machine and the single machine is realized.
The invention designs a method for accessing a system instantly by a single machine level, thereby improving the development efficiency of a control system and improving the flexibility and maintainability of system composition.
The control system of the invention adopts a bus form to be connected with the single machine, and completes the independent identification of the single machine through the unique identifier and the node distribution system. Each kind of single machine has respective minimized standard data transmission protocol, and the host machine and the single machine complete autonomous communication.
The invention provides an autonomous identification method, which defines the composition of unique identifiers, a control system host and each single machine can respectively initiate identification applications, and after the host is identified, the node address is automatically allocated to finish the autonomous identification of the single machine.
The invention provides an autonomous communication method, which defines standard communication formats and contents including communication instruction forms, byte lengths, types, resolutions and other attributes contained in the instructions according to physical meanings provided by the single computers, completes communication definition of each type of single computer, and completes autonomous communication and application after autonomous identification.
In the invention, multiple sensor single machines and actuator single machines used by the satellite control system can be accessed into the satellite control system in an information layer in real time, the replacement or the update of the single machines can be automatically completed, and the newly replaced single machines or the newly added single machines can be automatically identified and applied to the satellite control system. The invention can improve the development efficiency of the satellite control system, improve the flexibility and maintainability of the satellite control system, simultaneously, the single machine can be applied to different types of satellites, the design cost of the single machine can be leveled, and the purchase cost of the single machine can be reduced.
