Mechanics sensor array calibrating apparatus and working method thereof

Abstract

The present invention discloses a mechanical sensor array calibration device and the working method thereof. The device comprises locating transmission part and control part which is electrically connected with the locating transmission part; wherein, the locating transmission part comprises calibrated working platform and pressure head testing part; the pressure head testing part is connected with a force sensor through an extension head of a Z-directional linear stepper motor. Using the working method of the device adopts three stepper motors as the driving source; two stepper motors drive the coordinate motion of the slides on the guide rail to finish the location of coordinate point on the working platform; an extension of a linear stepper motor drives the pressure head to exert force on the tested sensor; when the force exerted by the pressure head achieves the set pressure valve, the singlechip collects the output of the tested sensor and the force sensor and the position coordinate of the tested sensor. The present invention is able to execute the choose and configuration of the calibrating mode and process according to the specific sensor array and the specific calibrating demand so as to enlarge the using range of the device.

Description

technical field [0001] The invention belongs to the field of sensor applications, in particular to a mechanical sensor array calibration device and a working method thereof. Background technique [0002] At present, sensor arrays, especially large-area, high-density dot-matrix sensor arrays, have more and more uses and irreplaceable roles in the field of detection technology. In particular, the emergence of large-area flexible array sensors has greatly promoted the application of array force sensors. [0003] Typical array sensor products, such as a pressure distribution test system launched by Tekscan Corporation of the United States, use a flexible array sensor. This sensor array is composed of two very thin polyester films. The inner surfaces of the two films are printed with column conductors and row conductors respectively. When the two films are put together, the crisscross row conductors and column conductors cross each other. , thus forming a dot matrix with severa...

However, the patent document does not disclose that the instrument to be tested is a sensor array, nor does it disclose the load cell used in the project, and there is also a large gap between the specific structure and specific operation of the calibration device and the patent of the present invention. Furthermore, it is very difficult to calibrate the sensor array using the calibration device
