Abstract
The utility model relates to a digital display slide caliper data gathering device based on USB, which comprises a main controller (1) and a host computer (3), wherein the main controller (1) which is used for being connected with a digital display slide caliper (2) is connected with the host computer (3) through a USB cable. The main controller gathers synchronous series impulse data output by the digital display slide caliper, and transfers the gathered data to the host computer through a USB, and the host computer controls software to implement the relative management functions of displaying, conserving and the like to the gathered data, and the measurement and management function can be effectively reinforced. A hardware interface is simple and has low production cost, and is easier to connect with a computer interface.
Description
Technical field
The utility model relates to a kind of data collector, specifically, relates to a kind of digital display calliper data collector based on USB.
Background technology
Digital display calliper compare with traditional slide calliper rule have convenient reading, characteristics intuitively, use more and more universal.Digital display calliper has data output interface, generally exports with the synchronous serial pulse.Existing digital display calliper data collector on the market, the typical hardware interface device is many and complicated, cost higher and is connected with computer interface inconvenient.
The utility model content
Technical problem to be solved in the utility model is, by a kind of digital display calliper data collector based on USB is provided, overcome the defective that existing digital display calliper data collector exists, further strengthen the measuring management function, and have that hardware interface is simple, cost is low, be easy to characteristics with computer interface.
The technical solution adopted in the utility model is as follows.
A kind of digital display calliper data collector based on USB comprises master controller and host computer, it is characterized in that: the master controller that is used to connect digital display calliper is connected by the USB cable with host computer.
