Abstract
The invention discloses a space key simulation circuit system which comprises an input chip, a single-chip microcomputer and an interface conversion chip which are electrically connected in sequence. The input chip is used for simulating USB signals into a keyboard port. The single-chip microcomputer is used for simulating keyboard triggering signals and sending signals to the interface conversion chip after receiving the signals of the input chip. The interface conversion chip is used for sending converted space key signals to a PC, and the PC is used for converting the space key signals into pressing-down space key signals. By means of the space key simulation circuit system, a space key is automatically started, the action that an operator operates the space key is replaced, equipment can be automatically started to conduct a next action after the equipment completes a previous action, time and labor are saved, unattended operation of the whole equipment is achieved, one operator is saved for each set of equipment, and thus the production cost is saved.
Description
Technical field
The present invention relates to a kind of space bar analog circuitry system.
Background technology
At present, in operation process, after the last action of equipment completes, after all needing to press space bar on the keyboard of equipment PC, equipment just can proceed next step action.The limitation of this mode is: on the one hand, needs to arrange the operation that operating personnel carry out pressing space bar on keyboard specially, waste of manpower, and the robotization that cannot realize streamline is unattended; On the other hand, device action is connected and needs manual control, cannot save manpower, thus add human cost.
Summary of the invention
For above-mentioned technical matters, the present invention discloses a kind of space bar analog circuitry system, comprising: the input chip be electrically connected successively, single-chip microcomputer, interface conversion chip; Described input chip is for the signal imitation of USB is become keyboard mouth; Described single-chip microcomputer is used for simulating keyboard trigger pip, and after the signal receiving described input chip, signal is sent to interface conversion chip; Described interface conversion chip is used for the PC space bar signal changed being sent to connection, and described PC is used for space bar signal to convert to press space bar signal.
The invention has the beneficial effects as follows that described space bar analog circuitry system starts space bar automatically, instead of the operation blank key action of operating personnel, can after equipment completes last action, automatic starting outfit carries out next step action, time saving and energy saving, achieve the Unmanned operation of whole equipment, every platform equipment has saved an operator, thus saves production cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of space bar analog circuitry system of the present invention.
In figure: 1, input chip; 2, single-chip microcomputer; 3, interface conversion chip.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail, can implement according to this with reference to instructions word to make those skilled in the art.
As shown in the figure, the present invention discloses a kind of space bar analog circuitry system, comprising: the input chip 1 be electrically connected successively, single-chip microcomputer 2, interface conversion chip 3; Described input chip 1 is for the signal imitation of USB is become keyboard mouth; Signal for simulating keyboard trigger pip, and after the signal receiving described input chip 1, is sent to interface conversion chip 3 by described single-chip microcomputer 2; Described interface conversion chip 3 is for sending to the PC of connection by the space bar changed signal, described PC is used for space bar signal to convert to press space bar signal.Input chip 1 is WIT122U chip; Single-chip microcomputer 2 is PIC12F508 single-chip microcomputers.Described space bar analog circuitry system starts space bar automatically, instead of the operation blank key action of operating personnel, can after equipment completes last action, automatic starting outfit carries out next step action, time saving and energy saving, achieve the Unmanned operation of whole equipment, every platform equipment has saved an operator, thus saves production cost.
Although embodiment of the present invention are open as above, but it is not restricted to listed in instructions and embodiment utilization, it can be applied to various applicable the field of the invention completely, for those skilled in the art, can easily realize other amendment, therefore do not deviating under the universal that claim and equivalency range limit, the present invention is not limited to specific details and illustrates here and the legend described.
