Abstract
The invention discloses a vibration wire type detection element. The detection element comprises a string wire, a bearing, a membrane and a permanent magnet, wherein one end of the string wire is fixedly connected with the bearing, and the other end of the steel wire is fixedly connected with the membrane and the permanent magnet is arranged in the middle of the steel wire. According to the vibration wire type detection element provided by the invention, the data is convenient to transport, process and store in such a way of converting the acting force into frequency signals output because the inherent frequency of an elastic element is changed under the force or pressure effect, therefore, the detection element has the characteristics of being small in volume, light in weight, high in resolution and the like; furthermore, the output signal is a vibrating frequency signals, the detection element is likely to be directly matched with a computer and other digital detection systems.
Description
Technical field
The present invention relates to checkout equipment field, be specifically related to a kind of type vibration wire detecting element.
Background technology
In mechanical field, being much difficult to the physical quantity (as pressure, flow, temperature etc.) directly measured, all needing by measuring by mechanical detection element.And current mechanical detection component structure is complicated, volume is comparatively large, complex operation during measurement, and resolution is not high.
Summary of the invention
The present invention, in order to overcome the deficiency of above-mentioned technical matters, provides a kind of type vibration wire detecting element, can solve above-mentioned technical matters completely.
The technical scheme solved the problems of the technologies described above is as follows:
A kind of type vibration wire detecting element, comprise string wire, supporting, diaphragm and permanent magnet, described string wire one end is connected with supporting and fixing, and the other end is fixedly connected with diaphragm, and the middle part of described string wire is provided with permanent magnet.
Described string wire the magnetic field that formed by permanent magnet surround.
When the bottom of diaphragm is subject to the effect of power, the initial tension of string wire changes, thus causes the natural frequency of string wire to change.After string wire exciting, by natural frequency vibration.Cut the magnetic line of force formed by magnet around it due to vibration, thus on vibratory string, produce the induced potential of alternation, the frequency of this electromotive force equals the natural vibration frequency of string wire.
Type vibration wire detecting element of the present invention utilizes flexible member under power or pressure effect, and its natural frequency changes, and acting force is converted to frequency signal and exports, be convenient to the transmission of data, process and storage, have that volume is little, lightweight, resolution high.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is structural representation of the present invention;
In figure, 1 is supporting, and 2 is string wire, and 3 is permanent magnet, and 4 is diaphragm.
Embodiment
A kind of type vibration wire detecting element as shown in Figure 1, comprise string wire 2, supporting 1, diaphragm 4 and permanent magnet 3, described string wire 2 one end is fixedly connected with supporting 1, and the other end is fixedly connected with diaphragm 4, and the middle part of described string wire 2 is provided with permanent magnet 3.Described string wire 2 magnetic field that formed by permanent magnet 3 surround.
Type vibration wire detecting element of the present invention utilizes flexible member under power or pressure effect, and its natural frequency changes, and acting force is converted to frequency signal and exports, be convenient to the transmission of data, process and storage, have that volume is little, lightweight, resolution high.Because output signal is vibration frequency signal, be easy to the digital detection systems such as direct and computing machine and support the use.
