Embodiment Construction
[0031] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0032] The coin sorting system is to judge the authenticity of all coins issued by the country, and to classify and count the value of various real coins. This system is applied to various banking systems, with fast clearing speed and high accuracy. The core component of coin sorting in this system is the eddy current sensor. The eddy current sensor is sensitive to the metal material, thickness, pattern, coin diameter, etc. False judgment and accurate judgment of which currency value, as well as quantity statistics.
[0033] Such as figure 1 As shown, the present invention provides a kind of coin sorting system, comprises double electric eddy current sensor 1, excitation synthesis circuit 2, filter processing circuit 3, DSP 4 and interface circuit 5, interface circuit 5 adopts MAX232 chip to realize,
[0034] Such as figure 2 As ...

The invention discloses a coin differentiating system and a coin differentiating method. Three sine excitation sources with different frequencies are loaded onto a transmitting probe of a sensor. When a coin passes through a dual-electric eddy current sensor, a signal receiving function of a receiving probe can be influenced, and existing coins issued in China can be differentiated by processing received signals, so the types, quantity and genuineness of the coins can be determined immediately when the coins pass through the sensor. When the coins are tested on a sample machine, the coin differentiation speed can reach 1,500 pieces / minute, the differentiation accuracy rate of genuine coins can reach 99.99 percent, and the differentiating rate of counterfeit coins can reach 100 percent.
Description
technical field [0001] The invention relates to a coin sorting system and a coin sorting method, belonging to the technical field of financial equipment. Background technique [0002] The core components of foreign coin sorting systems have been monopolized, and domestic coin sorting systems are rare, but there are also problems such as slow sorting speed, low sorting accuracy, poor scalability of self-learning coins, and often misjudgment of game coins as real Coins, or real coins are misjudged as counterfeit coins, and there are shortcomings such as missing the number of coins. Contents of the invention [0003] The technical problem of the present invention is: to overcome the deficiencies of the prior art, to provide a coin sorting system and a coin sorting method, to classify and count the various existing coins issued, and to detect the counterfeit coins mixed in the real coins , The coin sorting core component system has high precision, high speed and high accuracy...
