Abstract
The utility model relates to a digital display caliper multiway collector, comprising a singlechip, 2-8 digital display caliper signal input ports, and a signal level conversion cell connecting the singlechip with a plurality of digital display caliper signal input ports, wherein the singlechip is connected respectively with a USB interface, a power indicating light and a status indicating light; the singlechip, the digital display caliper signal input ports, the USB interface, the signal level conversion cell, the status indicating light and the power indicating light are all contained by one shell, and the status indicating light and the power indicating light are both connected with a current-limiting resistance. The utility model has the advantages that a plurality of digital display calipers can be connected simultaneously; the collected data can be transmitted to a computer through the USB interface so as to save computer interface. Furthermore, the utility model has the advantages of simple structure, small volume, numerous collecting interfaces and convenient carrying.
Description
Technical field
The utility model relates to a kind of digital display calliper multi pass acquisition device that is used to gather a plurality of digital display calliper data, belongs to data acquisition equipment.
Background technology
Digital display calliper is directly perceived, easy to use with its reading, the advantage of diverse in function, uses more and more widely in daily dimensional measurement.The digital display calliper that we contacted generally all has computer interface, the data of measuring can be transferred to computing machine by specific format, to reach the purpose that computer data acquiring is handled.But one all needs a RS232 interface or USB interface to slide calliper rule, this just following two problems occur, one: present personal computer RS232 Application of Interface has been fewer and feweri, notebook computer nearly all is not with the RS232 interface, has so just limited the range of application of the slide calliper rule data acquisition of band R232 interface; Its two: the computing machine USB interface is limited, can not support a plurality of slide calliper rule data acquisitions.
The utility model content
The purpose of this utility model is to provide a kind of digital display calliper multi pass acquisition device, and this collector can be concentrated and gather a plurality of digital display calliper data, thereby alleviates computer interface pressure.
In order to achieve the above object, the technical solution adopted in the utility model is:
A kind of digital display calliper multi pass acquisition device, comprise single-chip microcomputer, 2～8 digital display calliper signal input ports, and the signal level converting unit of connection single-chip microcomputer and a plurality of digital display calliper signal input ports, described single-chip microcomputer is connected with USB interface, power light and status indicator lamp respectively, and described single-chip microcomputer, digital display calliper signal input port, USB interface, signal level converting unit, status indicator lamp and power light are a shell and comprise.
Status indicator lamp of the present utility model and power light all are connected to current-limiting resistance.
The utlity model has following beneficial effect: (1) can connect a plurality of digital display callipers simultaneously, gives computing machine with the data that collect by a USB interface concentration of transmissions, to save computer interface; (2) this equipment have simple in structure, volume is little, gather many, the portable advantages of port.
Description of drawings
The structural representation of the digital display calliper multi pass acquisition device that Fig. 1 provides for the utility model.Among the figure: 1 is single-chip microcomputer, and 2 is the signal level converting unit, and 3 is the digital display calliper signal input port, and 4 is USB interface, and 5 is status indicator lamp, and 6 is power light.
Embodiment
After USB interface 4 is inserted into the computing machine USB interface, USB interface 4+the 5V power supply is added to the power supply processing section of single-chip microcomputer 1 inside, from single-chip microcomputer 1 port output+3.3V stabilized voltage supply, this power supply supplies with single-chip microcomputer 1 and signal level converting unit 2 is used, and this moment, power light 6 was lighted with the expression power connection.Single-chip microcomputer 1 provides activation bit by D+, D-data-signal alignment computing machine again, then can carry out normal USB communication with single-chip microcomputer 1 after machine drive installation to be calculated is good.Whether single-chip microcomputer 1 detects repeatedly has digital display calliper to insert digital display calliper signal input port 3, after digital display calliper inserts digital display calliper signal input port 3, and the state of the corresponding digital display calliper of status indicator lamp 5 indications.The digital display calliper input signal is read in by the port of single-chip microcomputer 1 after signal level converting unit 2 is converted to the required signal level of single-chip microcomputer 1, obtain the measured data of current this digital display calliper through single-chip microcomputer 1 internal processes analyzing and processing, these data deposit single-chip microcomputer 1 specified memory address space in by certain format.After single-chip microcomputer 1 was finished an all of the port scanning, single-chip microcomputer 1 was passed to computing machine by USB interface with resulting data, has so just finished the data acquisition of a multichannel digital display calliper.
Claims (2)
1. digital display calliper multi pass acquisition device, comprise single-chip microcomputer (1), 2～8 digital display calliper signal input ports (3), and the signal level converting unit (2) of connection single-chip microcomputer and a plurality of digital display calliper signal input ports, it is characterized in that, described single-chip microcomputer (1) is connected with USB interface (4), power light (6) and status indicator lamp (5) respectively, and described single-chip microcomputer, digital display calliper signal input port, USB interface, signal level converting unit, status indicator lamp and power light are a shell and comprise.
