Abstract
The utility model discloses a detection and control device for an aircraft integrated universal test interface, in order to solve the technical problem that conventional aircraft test interfaces are complicated. Signals on an output interface are acquired and transmitted to a slave controller through an analogy switch on a protocol detection circuit and an A/D acquisition circuit. The classes of the signals are determined and the result is sent to a master controller in a data monitoring circuit. The master controller controls a multipath switch based on the result and sends the signals detected to corresponding transceivers. The master controller uploads signals detected by the transceivers to a host computer through serial ports, thereby completing the monitoring and controlling of signals. Since hardware interfaces are remotely detected and controlled through software, frequent manual shifting interfaces and controlling the opening of interfaces can be avoided. Computer protocol of remote automatic interface identification is realized, and hardware interface configuration and shifting operation can be completed automatically. The interface data can be monitored and stored as required.
