A coin recognizer and coin recognition method

Abstract

A coin validator and a coin identification method, the coin validator comprises: a housing and a coin passage arranged in the housing, the upper end of the coin passage is a coin slot, the end of the coin passage is a coin drop opening, and a coin storage room is arranged below the coin drop opening , There are rollers in the coin channel, and the surface of the rollers is provided with a raised spiral ridge. After the coin is put into the coin slot, it is placed on the spiral ridge. A stepping motor is connected under the roller. When the roller rotates horizontally, the spiral The coin on the shaped back moves up and down; the coin channel is provided with a recognition sensor module for identifying the authenticity and material of the coin; a processor is also provided on the housing, and the processor is electrically connected to the stepping motor and the recognition sensor module respectively. It is used to control the forward rotation or reverse rotation of the stepping motor according to the identification information of the identification sensor module.

Description

technical field [0001] The invention relates to the technical field of self-service cash registers, in particular to a coin recognizer and a coin recognition method. Background technique [0002] With the continuous improvement of science and technology and the continuous development of commercial automation, more and more self-service cash registers are widely used and play an important role in business behavior. Common self-service cash registers include: bus Coin-operated machines, vending machines, subway and high-speed rail self-service ticket machines, self-service recharge machines, self-service payment machines, etc. There are many advantages of self-service equipment. It can perform uninterrupted work without the limitation of time and place. At the same time, it can reduce labor costs, improve work efficiency, and provide more convenience for consumers and businesses. [0003] Coins, as an important settlement currency in payment behavior, play a pivotal role in t...

AI Technical Summary

Problems solved by technology

[0004] At present, the coin recognition equipment on the market has more or less defects, such as: single currency recognition, slow coin recognition and processing speed, insufficient recognition accuracy, poor anti-theft performance, easy to block coins, etc., which cannot meet the needs of self-service equipment. The need to realize the coin payment function

Moreover, the existing coin recognition module has a large volume, and the separate design of the counterfeit coin return port is an important reason for the large volume. The increase in volume not only increases the structural complexity of the module, but also increases the wiring harness and mold. fees and costs

In addition, the existing coin identification equipment often only relies on parameters such as volume, weight, and size as the basis for coin identification, and cannot achieve accurate identification.

For the existing comparative coin acceptors, it is necessary to place the received sample coins in the comparison bin of the coin acceptor as a sample before they can be used. The coins that can be received at the same time are relatively single, and there are many conditions.

In terms of intelligence, the existing coin validator program upgrade is cumbersome, and the device needs to open the shell to upgrade the program, which is not conducive to operation; it does not have the coin learning function, the user cannot operate by itself, and cannot recognize the newly issued coin currency. It can only be identified after returning the device to the manufacturer to update the new currency data; it also does not have a serial communication interface, and cannot be integrated with other peripherals
