[0020] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] For motor control systems in aerospace, especially low-power motor control systems, the integrated control unit typically employs a time-division multiplexing data acquisition method. The motor control system is a centralized-distributed structure composed of a central program unit and multiple remote acquisition and editing units. There is a need to provide a control system that utilizes 1553B data bus technology, a technology maturely applied in modern avionics and spacecraft data management systems, achieving a simple structure, convenient terminal expansion, and high reliability. It should be suitable for centralized-distributed acquisition systems.

[0022] The aerospace low-power motor control system based on 1553B bus technology consists of a 1553B bus communication module and a low-power motor control and drive circuit. The motor control system is connected to the aerospace equipment via the 1553B bus, enabling the low-power motor controller to act as a bus RT device, and the BC device to organize the RT devices to complete the control of key components on the aerospace equipment.

[0023] The 1553B bus system mainly consists of three parts: the bus controller (BC), the remote terminal (RT), and the bus monitor (BM). The main hardware components are the bus controller (BC), the remote terminal (RT), and the optional bus monitor (BM). Typically, these three parts are integrated through a single multiplexer interface (MBI).

[0024] The 1553B data bus uses a command / response communication protocol and has three types of terminals: (1) Bus Controller (BC), which is a terminal on the bus assigned to perform tasks of establishing and initiating data transmission. (2) Remote Terminal (RT), which is the interface between the user subsystem and the data bus. It extracts or receives data under the control of the BC. (3) Bus Monitor (BM), which "monitors" the information transmission on the bus to record and analyze the data sources on the bus, but it does not participate in the communication of the bus itself.

[0025] The technical solutions provided by the various embodiments of this application are described in detail below with reference to the accompanying drawings.
