Embodiment Construction
[0015] The invention mainly aims at the universal serial bus in aerospace, and proposes a universal interface detection, monitoring and control circuit. The universal serial port DB9 is used to transmit data, so as to reduce the complexity of conversion between various interfaces, improve the universal row, and provide convenience for the implementation of data acquisition and software algorithms.
[0016] refer to Figure 1-8 The general interface detection and controller for aircraft integration test includes input interfaces 1-n, interference shielding circuits 1-n, interface control circuit, protocol detection circuit, data monitoring circuit and serial port, the serial port model is RS232.
[0017] The signal passes through the input interface 1~n, passes through the interference shielding circuit, and reaches the interface control circuit. The interface control circuit will detect that a signal is connected to the protocol detection circuit. The protocol detection circu...

The present invention discloses a detection and controller for aircraft integration test general interface for solving the technical problem that the prior aircraft test interface is complicated. The technical scheme is that an analogue switch and an A / D collecting circuit in a protocol detection circuit are used for collecting signals on an input interface to a secondary controller; after types of the signals are judged, the judging result is transferred to a primary controller of a data monitoring circuit; the primary controller controls a multi-way switch according to the judging result totransmit the detected signals to a corresponding transceiver; the primary controls uploads the signal detected by the transceiver to an upper computer by a serial port, so as to complete the monitoring and control of the signals. Frequent manual interface switchovers and on / off control of the interface are avoided via remote monitoring and controlling the hardware interfaces by software, so that automatic identification of interface protocol type of computer, automatic configuration of hardware interface switch and switching operation are realized; and the interface data can be monitored and stored according to requirements.
Description
technical field [0001] The invention relates to an interface detection and controller, in particular to a general interface detection and controller for aircraft integration testing. Background technique [0002] In the ground integration test experiment of aerospace vehicles, the signal transmission between various systems is complicated, and a large amount of data exchange is required. During testing, these signals need to be connected to various interfaces and be detected, analyzed and controlled. As we all know, there are many interface devices, and the detection data interaction is complicated during the ITU test, so it is necessary to manually connect the corresponding interface to the detection device or disconnect it. When the test object has many types of interfaces and complex lines, such work is very cumbersome. It is necessary to manually confirm and manually plug and unplug each line, and then check one by one after connecting the corresponding lines. error. ...
