Abstract

A method and system for detecting currency, relates to banknote detectors, to solve the problem of accuracy rate causes the banknote detectors can not be used. The system includes a UV light source, a white light source, an image acquiring device, a controller, and a prompting device. The white light source and the UV light source are faced to each other. A currency detecting channel is formed between the white light source and the UV light source. A micro-switch and a pause switch are located on a controlling loop of the UV light source. A trigger of the micro-switch is located in the currency detecting channel. The pause switch and the micro-switch are in series connection. The image acquiring device and the white light source are located at a same side of the currency detecting channel. The image acquiring device outputs a currency image to a display device.

Claims

1. A system for detecting currency, comprising:

a UV light source;

a white light source and the UV light source faced to each other, and a currency detecting channel formed between the white light source and the UV light source;

an image acquiring device and white light source located a same side of the currency detecting channel, the image acquiring device outputting a currency image to a display device;

wherein a micro-switch is located on a controlling loop of the UV light source;

when a currency enters the currency detecting channel, the micro-switch is triggered to turn on the UV light source and turn on the white light source;

wherein a pause switch is located on a controlling loop of the UV light source, and the pause switch and the micro-switch are in series connection.

2. The system for detecting currency of claim 1, wherein the pause switch is a manual switch or an electrically controlled switch.

3. The system for detecting currency of claim 1, wherein the display device is a display screen.

4. The system for detecting currency of claim 1, further comprising a controller, wherein the controller is electronic connected to the image acquiring device, and the controller is electrically connected to the pause switch.

5. The system for detecting currency of claim 4, further comprising a prompting device, wherein the prompting device comprises one or more visual prompts, sound prompts, and vibration prompts.

6. A method for detecting currency, comprising:

acquiring image, a UV light source and a white light source turned on by that a micro-switch is triggered while a currency enters the currency detecting channel, an image acquiring device acquiring a currency image under a fluoroscopy by the UV light source;

the controlling loop of the UV light source comprises the micro-switch and a pause switch, and the micro-switch is connected in series with the pause switch;

displaying, the image acquiring device outputting the currency image to the display device to be displayed.

7. The method for detecting currency of claim 6, further comprising automatic outputting, wherein the image acquiring device also outputs the currency image to a controller;

the controller includes a standard image, the controller compares and judges the currency image with the standard image and outputs.

8. The method for detecting currency of claim 6, wherein comprising:

turning off the UV light source and turning on the while light source;

acquiring another image, displaying, and automatic outputting.
