Detailed description of the invention
The present invention is described in detail for each embodiment shown in below in conjunction with the accompanying drawings, but it should explanation
It is, these embodiments not limitation of the present invention that those of ordinary skill in the art implement according to these
Equivalent transformation in mode institute work energy, method or structure or replacement, belong to the guarantor of the present invention
Within the scope of protecting.
Shown in ginseng Fig. 1, Fig. 1 is the structured flowchart of a kind of multicontact switch of the present invention.
This multicontact switch mainly by main control module 10, data acquisition module 20, data disaply moudle 30,
Data processing module 40 and human-computer interaction module 50 form.
Main control module 10 is for making between each module framework agreement coordination and the phase intercommunication according to system
Letter, and realize man-machine interaction.Main control module provide user interface, user by sending instruction, master control
Module is by dispatching each Implement of Function Module user view.
Data acquisition module 20 is for gathering the change in resistance data of switch ends, and the resistance that will change
Value is converted into digital quantity and is delivered in computer be analyzed processing.The data acquisition function of this module by
Data acquisition function card realizes.
Data disaply moudle 30 is for showing the data gathered.
Data processing module 40 data being used for gathering process, so that multi-point touch switch
Button is more stable.Before processing data, first acquire one group of signal data, due to the number collected
According to there is certain fluctuation, so needing to need to process to the data collected.The present embodiment is adopted
By the mode of multidraw, the signal collected being carried out five sub-samplings, data are entered by method of averaging
Row processes.
Human-computer interaction module 50 shows for data input and result, and the present embodiment is with LabWindows
For front panel, it is provided that abundant graphical control, traditional instrument working method can be simulated, at front panel
Control required for upper placement and indicator, it is achieved instrument controlling and data input show with result.When
During operation program, only front panel occurs on the screen of computer, as connecing of virtual measurement and user
Mouthful.As long as controlling parameter accordingly on demand at writing on front panel, complete the setting of sampling channel,
Just various interaction can be carried out.
The present embodiment uses resistance type multi-point touch switch to coordinate data collecting card to carry out adopting of switch data
Collection, then communicated by USB interface, the data collected by capture card are delivered into terminal unit
Virtual instrument, and the data being gathered capture card are analyzed and process, thus realize man-machine interaction.
I.e. gather the change of multi-point touch-control panel resistance value with front-end collection card, and passed through USB interface even
Receive PC, carry out senior process and various further analysis by PC, and both divide
Leave and also can work independently.Wherein, front end data acquisition specifically includes that touching multi-point touch by people opens
Pass makes switch ends resistance change；By data collecting card, gather the change of switch ends resistance；
The resistance of change is entered computer by USB interface transmission；By USB interface by the letter of change in resistance
Number it is sent to computer.Computer analyzing and processing specifically includes that reception and stores front end data acquisition card biography
The resistance of the change brought；The situation of change of resistance during display；The increased resistance value collected is entered
Row is analyzed；Value analysis drawn and computer carry out interaction.
Front end multi-point touch switch is divided into again resistance switch, part of data acquisition, process and communications portion.
, the change of resistance will be there is when human body touch to resistance switch when in resistance switch part.Data acquisition
The resistance of change will be acquired by part.System has been directed to use with data acquisition at data processing section
Card.Gathered the change of resistance value by data collecting card, and the value collected is carried out preliminary treatment, right
The signal collected carries out showing and the control of USB communication module.
The resistance type multi-point touch switch that the present embodiment provides, touches multi-point touch by staff and switchs, draw
Playing the change of resistance, after staff touches the touch panel of multi-point touch switch, capture card will be right
The resistance of two ends change is acquired, delivers to computer disposal, analysis.This multi-point touch switch has spirit
The features such as sensitivity is high, easy and simple to handle, volume is little, power consumption is low, easy to use.
This multicontact switch can arrange five touch points, the changing value of the resistance data acquisition mouth by two ends
