The detection system comprises a 1553B simulation card, a telecontrol and telemetering board and a control system; the 1553B simulation card is plugged in a computer host, and is connected with an aerospace device through a 1553B cable; the telecontrol and telemetering board, which adopts a singlechip architecture, is connected with the computer through a USB interface, and is connected with the aerospace device through a dedicated cable to transmit telecontrol signals and telemetering signals; and the control system is used for periodically querying the state of the aerospace device, reading satellite data, sending time code messages to the aerospace device and sending instructions to the aerospace device to change the operation mode of the aerospace device or configuring satellite operation parameters. The detection system utilizes the mature 1553B simulation card and a general-purpose function library thereof and designs a general-purpose control interface to simulate functions such as the control of the aerospace device, data acquisition, message broadcasting and datainjection, and thereby a good testing platform is provided for aerospace products.

Description

Technical field [0001] The invention relates to a ground detection system for aerospace, in particular to a satellite communication 1553B ground detection system and a detection method thereof. Background technique [0002] The current 1553B ground detection system mostly uses a single-chip computer and a 1553B control chip to control the 1553B communication. The circuit board contains both AD and DA chips. The AD chip completes the remote measurement data acquisition and input, and the DA chip completes the remote control command output. This kind of detection system and computer communication method mostly adopts serial port or USB mode. The serial port method is easy to program but the data transmission rate is low and most of the notebook computer serial ports are gradually cancelled, which limits its application. The USB method has a wide range of applications and fast speed but more programming. Complicated, a common difficulty in the above two solutions lies in the definit...

Problems solved by technology

This kind of detection system and computer communication mostly adopts serial port or USB. The serial port is easy to program, but the data transmission rate is low, and the serial port of most notebook computers is gradually canceled, which limits its application. The USB method has a wide range of applications and fast speed, but the programming is relatively slow. Complicated. A common difficulty in the above two schemes lies in the definition of the data format between the single-chip microcomputer and the computer and the regulation of the communication protocol. The formats and protocols designed by different developers are quite different. The above two schemes have high program complexity between the computer and the single-chip microcomputer , poor reliability, poor versatility
