1553B bus network test system and method

Abstract

The invention discloses a 1553B bus network test system which is characterized by comprising a signal transmitter, a signal receiver and a standard attenuator used for calibrating the signal transmitter and the signal receiver, wherein the signal transmitter and the signal receiver are separately used for transmitting and receiving signals via different sub-ports of a 1553B bus network, and judgesthe fault condition of the 1553B bus network according to the current for transmitting the signal or the insertion loss of the received signal. Via a simple mathematical model, the relation between various faults of the 1553B bus network and the insertion loss is deduced; a set of test system composed of a signal generator and the signal receiver is used for measuring the insertion loss of the 1553B bus network, so that the various fault modes can be positioned in the physical layer, the fault points can be prompted and the test parameters can be recorded, and thus an effective means is provided to the 1553B bus network using and maintaining personnel for directly finding and positioning the faults, performing routine inspection to troubleshoot, and directly finding and positioning doubtful faults.

Description

【Technical field】 [0001] The invention belongs to the field of electronic measurement, in particular to a 1553B bus network testing system and method. 【Background technique】 [0002] The MIL-STD-1553B bus network has been widely used in the field of weapons and equipment using the MIL-STD-1553B data bus technology. How to quickly and accurately test the MIL-STD-1553B network to confirm the integrity and reliability of its network system is an urgent problem to be solved by the use and maintenance department. In the past, qualitative methods were mostly used in the testing and maintenance of MIL-STD-1553B bus network to preliminarily judge whether the MIL-STD-1553B bus network is intact. However, it is impossible to determine the type of fault and locate the fault. 【Content of invention】 [0003] The purpose of the present invention is to provide a 1553B bus network testing system and method, which can accurately determine the fault type and locate the fault point.
