Example Embodiment

[0025] Such as figure 1 In the coin identification device shown, the coin slot 1 is provided on the side wall of the box 3 (in actual use, the coin slot can also be provided on the top wall of the box as needed), and the coin slot 1 is located at the inner opening of the coin slot A guide groove 2 with an inclined angle is provided at the edge. In order to ensure that the free fall of the coin hitting the base plate is loud enough and does not damage the coin, the linear distance between the lower edge of the guide groove and the surface of the base plate should be controlled within the range of 5cm-100cm, preferably 10-50cm. In order to avoid sound reflection, the inner wall surface of the box is coated with sound-absorbing coatings 4 and 5 are the base plates placed on the bottom of the box. Its upper surface is also inclined to the horizontal plane, and there is a fixed connection on the base plate. The sound sensor 6.7 is two parallel upper and lower weighing plates (parallel...

Abstract

The invention relates to a coin identifying or discriminating device and method, especially relating to the discrimination of the true coins from the false coins. The method vertically slides the tested coin along a guiding groove down onto a substrate, collects a sound signal emitted by the coin as striking the substrate through sound sensor, directly sends the sound signal or sends the sound signal amplified by a power amplifier to a frequency spectrum analyzing device for making frequency spectrum analysis so as to obtain an inherent frequency of the tested coin, and compares the inherent frequency with a standard data in a frequency spectrum standard memory for making frequency spectrum discrimination; then uses a pressure sensor to measure the weight of the tested coin and sends the generated force signal amplified by a power amplifier into a weight analyzing device and calculates to obtain the weight of the tested coin and compares it with a standard data in a weight standard memory for making weight discrimination; then by an operational policy maker, synthetically analyzes and obtains the final discrimination result. The discriminating device has simple structure, lower manufacturing cost, and high identifying accuracy, applied to identification of various coins and having a wide application prospect.

Description

Technical field: [0001] The present invention relates to a coin identification or recognition device and method, in particular to a coin identification device and method, and also to the application of frequency spectrum analysis technology. Background technique: [0002] With the continuous prosperity of the market economy, vending machines have been widely used, making the circulation of coins larger and larger. At the same time, a large number of counterfeit coins have also appeared, which has affected the legitimate interests of operators. Therefore it is very necessary to develop a coin identification device with simple structure, high identification rate and low cost. [0003] In the prior art, the identification equipment of coins mainly realizes the identification of denomination, coin type and authenticity of coins by measuring different physical characteristics of coins. For example, using an optical method to detect the pattern of the coin; or using a magnetic s...
