Description
Technical field
The invention belongs to the technical field of automation control, relate in particular to a kind of output interface device, its energyEnough export polytype signal.
Background technology
Along with scientific and technical development, in electronic technology, the requirement of signals collecting, output is also comeHigher, the particularly collection to signal with different type, transmission. Traditional signal output interface circuit is mainFor: according to demand, the output interface of design specialized type. The shortcoming of this traditional way of output is exactly notFlexibly, specific circuit can only be exported specific signal type, after front end signal type changes,Need to again circuit board be designed and be revised, just can obtain correct output signal, can bring thusThe lengthening of lead time and the waste of cost, and the printed board area that takies of each road signal output interfaceGreatly, be unfavorable for integrated.
There is polytype signal demand collection output in industrial automatic control field. But existing letterNumber output intent can only be the signal of single rice delivery outgoing interface output single type, for example, and digital output interfaceCan only export single data signal, simulation output interface can only export single analog signal etc., whenWhile existing polytype collection signal to transmit in industry spot, can only redesign system could selectSelecting the signal of other types exports. But for realizing the versatility and the body that reduces controller of controllerLong-pending, the best way is the common output mouth of realizing polytype collection signal, inputs which kind of amount, controlDevice processed just gathers which kind of amount of output. But because the gap between signal with different type is larger, be therefore difficult to realityThe compound output transmission of existing polymorphic type semaphore.
Summary of the invention
The technical problem to be solved in the present invention is the defect that overcomes prior art, provides a kind of output interface to establishStandby, it can realize the common output mouth of polytype collection signal, which kind of is inputted and measure this equipment and just adoptWhich kind of amount of collection output, has improved product versatility, and be conducive to reduce circuit board size, be conducive to collectionCheng Hua.
