Switching device

Abstract

The present invention provides a change-over device comprising a signal receiving end, at least a signal transmitting end, at least a standby end, a programmable logic device and a jumper wire setting device comprising at least a jumper wire setting end, wherein, the signal receiving end is used for connecting the signal output end of a hardware, the signal transmitting end and the standby end are used for connecting the signal input end of another hardware, the programmable logic device comprises at least an input pin that is correspondingly connected with at least a signal receiving end, atleast an output pin that is correspondingly connected with at least a signal transmitting end, at least a standby output pin that is correspondingly connected with at least a standby end, and a control pin that is connected with the jumper wire setting device, and when the signal transmitting between the signal receiving end and the signal transmitting end is failed, the programmable logic deviceis driven by changing the level state of the control pin through setting the jumper wire setting device to output the failed transmitting signals to the standby end. Direct substitution change-over device using and manual wire jumping are avoided by using the change-over device, and time and cost are both saved.

Description

technical field [0001] The invention relates to an electronic device, in particular to an adapter device. Background technique [0002] At present, the method of connecting a switching device between two pieces of hardware is often used for signal transmission between the two pieces of hardware. output terminal, the input terminal of the adapter device is connected to the signal output terminal of a hardware, and the output terminal of the adapter device is connected to the signal input terminal of another hardware, so that the signal of the signal output terminal of the first hardware can be It is transmitted to the signal input of the other hardware, but the data line on the conversion device is often short-circuited or disconnected due to pollution with oil, debris, etc., or other reasons, causing some signal transmission failures on the conversion device , in view of this situation, the traditional processing method is to use a spare data line to manually replace the da...

[0002] At present, the method of connecting a switching device between two pieces of hardware is often used for signal transmission between the two pieces of hardware. output terminal, the input terminal of the adapter device is connected to the signal output terminal of a hardware, and the output terminal of the adapter device is connected to the signal input terminal of another hardware, so that the signal of the signal output terminal of the first hardware can be It is transmitted to the signal input of the other hardware, but the data line on the conversion device is often short-circuited or disconnected due to pollution with oil, debris, etc., or other reasons, causing some signal transmission failures on the conversion device , in view of this situation, the traditional processing method is to use a spare data line to manually replace the data line with signal short circuit or open circuit on the adapter device, or directly replace a new adapter device, although these two methods can solve the problem. The problem of short circuit or open circuit of the data line of the transfer device, but the timeliness is poor, and the implementation is cumbersome, resulting in waste of time and cost
