Description
Technical field
The utility model relates to a kind of cable device connection status detection, is applicable to carry out connection status detection by transmission, received code in the training of cable connecting analog.
Background technology
In the time making the hardware-in-the-loop simulation simulator that is used for operation training, need to judge each interface cable connection on equipment, simulate corresponding phenomenon.
The at present judgement to cable connection, is generally that each I/O mouth is subject to processing device control and produces successively signal, and all the other I/O mouths judge connection status according to receiving signal.But more for interface, especially interface distribution is far away, while needing two processors to control respectively, the locking phase of time is to difficulty.Realize difficulty and cost promotes greatly.
Utility model content
In order to address the above problem, the utility model provides a kind of cable device connection status detection.This device can be fast, stable, complete cable connection between each interface easily and detect, and can send connection status.
The utility model solves the technical scheme that its technical matters adopts:
A kind of cable device connection status detection, comprise processor circuit and multiple I/O interfaces for being connected with cable, wherein, described processor circuit and multiple I/O interface are arranged on insulating base, described processor circuit is connected with each I/O interface circuit respectively by pin, and this processor circuit is also connected with outside by USB interface and/or network interface.
As improvement of the present invention, two or more in described I/O interface are interconnected to form signal path by wire.
As improvement of the present invention, the one or more I/O interfaces during wherein one or more the I/O interfaces in described device can install with another are respectively interconnected to form signal path by wire.
I/O interface is subject to processing device control and produces identification code.I/O interface receives and is connected the coding sending processor processing that I/O interface sends, and detects I/O interface annexation the form transmission with code.
Processor (for example single-chip microcomputer) pin relies on hardware circuit to use as independent I/O interface.Single-chip microcomputer makes interface send successively the coding with independent information, other interfaces receive coding by institute's connection cable, according to the coding representative interface number receiving, and connection status is transmitted by the mode such as USB interface, network for form of code, thereby realize coding transmission and the receiving trap that cable connecting analog is trained.
In the utility model, can be used in conjunction with by more than enough table apparatus, to expand I/O interface quantity simultaneously.
The beneficial effects of the utility model are, both can each I/O mouth connection status be detected and be transmitted with the form of code, again can multiple equipment collaboration work, expand interface quantity.
