Embodiment Construction

[0024] Below in conjunction with accompanying drawing technical scheme of the present invention is described in detail as follows:

[0025] The coin centrifugal drive system is set up, including the motor, the centrifugal feeding tray, the toothed belt transmission mechanism and the limit mechanism; the vertically upward fixed motor is equipped with a rotating centrifugal feeding tray, and the centrifugal feeding tray rotates with the motor, and the centrifugal feeding tray is surrounded by Bucket-shaped silo, the coin samples in the silo generate centrifugal force with the high-speed rotation of the centrifugal feeding disc. The limit mechanism is connected to the outside of the outlet of the centrifugal feeding tray to limit the samples with thickness exceeding tolerance from entering the coin path. The toothed belt transmission mechanism is close to the outlet of the centrifugal feeding tray and the limit mechanism, and brings the sample of appropriate thickness into the co...

Abstract

The invention relates to a magnetic coin high-speed identification device, wherein the identification of the authenticity of coins comprises the following steps of: scanning magnetic parameters of the surface of a sample to be detected to acquire fluctuation signals of the magnetic parameters of the surface of the sample to be detected, and comparing the acquired fluctuation signals with the preset fluctuation signals of real coins to identify the authenticity of the sample. The device of the invention is provided with a coin centrifugally driving system, a control system, a coin surface magnetic signal acquiring system, a data analyzing system and a false coin eliminating system, wherein the coin centrifugally driving system sequences coins in a special coin channel and enables the coinsto pass through the special coin channel at high speed; the control system controls coordinated actions of each system and human-computer interfaces; the coin surface magnetic signal acquiring systemscans magnetic signal fluctuation of coin surfaces when the coins pass through the system; when the coins pass through a sensor at high speed, the magnetic sensor acquires three groups of fluctuationsignals and converts the signals into digital signals, and the data analyzing system compares the scanning signals with the digital signals for analyzing; and the false coin eliminating system strikes false coins by using an electromagnetic valve according to control system signals, thereby eliminating the false coins.

Description

technical field [0001] The present invention relates to a device for identifying the authenticity of coins, in particular to a high-speed identification device for magnetic coins, wherein the identification of the authenticity of coins is based on scanning the magnetic parameters of the surface of the detection sample to obtain the fluctuation signal of the magnetic parameter of the detection sample surface, compared to The preset fluctuation signal for real coins, so as to judge the authenticity of the samples. Background technique [0002] In recent years, countries have paid more and more attention to the mass anti-counterfeiting and machine-readable identification performance of coins. The euro, which represents the advanced level of coinage in the world, has extensively solicited opinions from the society long before the design, especially paying attention to soliciting opinions from the European Vending Machine Alliance EVA. With the release of the euro came vending m...
