Embodiment 1

[0035] Experimental equipment: color sensor TCS230, single-chip microcomputer AT89S52, display LCD1602A, 5V DC power supply, single infrared reflective sensor, objects of different colors, multimeter, etc. Connect the color sensor TCS230 and the single infrared reflective sensor with the microcontroller AT89S52, and then connect the microcontroller with the display LCD1602A, the hardware schematic diagram is as follows figure 1 .

[0036] When working, supply 5V DC power to the microcontroller, and place the device in an environment without other color interference. At this time, the 4 LED lights on the TCS230 will emit white light, and the device can work normally after a short white balance. Assuming that the prices of food on different color plates are different, LED lights will produce light of the corresponding color when illuminated on a plate. Different color lights such as red, green, and blue have different wavelengths and frequencies. When TCS230 receives different c...

Embodiment 2

[0045] see you again figure 2 An automatic pricing system for dinner plates is shown, including:

[0046] Color sensor TCS230, used to collect the color of the bottom of the plate;

[0047] Single-chip microcomputer AT89S52, used to calculate the meal price corresponding to different colors;

[0048] The display screen LCD1602A is used to display the meal cost.

[0049] Further, it also includes a single infrared emitting sensor, which is used to start the work of the single-chip microcomputer AT89S52.

[0050] It should be pointed out that the principle and implementation process of Embodiment 2 are the same or similar to those of Embodiment 1, so the repeated parts thereof will not be repeated here.

[0051]In addition, what is described in Example 1 is the pricing process for each colored dinner plate one by one. If a transparent tray is designed, there are a corresponding number of grooves on the transparent tray for placing the dinner plate. The dinner plate sits in ...

Abstract

The invention discloses a color recognition-based automatic pricing method for dinner plates and a system thereof. First, after a color sensor collects the color of the bottom surface of the dinner plate, the color signal is sent to a single-chip microcomputer; Then, the display screen will display the corresponding charging price according to the received price signal. The present invention has the following beneficial effects: 1) Use color features to collect color signals, and use programs to realize pricing, which is associated with common card swiping systems and is easy to be popularized; 2) Compared with traditional cash register methods, it has the advantage of convenience and quickness. Chip pricing is simpler, cheaper, and more flexible; 3) When the system is running, it is unmanned and more advanced; 4) Machine computing is more efficient, so it is more fair.

Description

technical field [0001] The invention relates to the fast food neighborhood, and more specifically relates to a color recognition-based automatic pricing method for dinner plates and a system thereof. Background technique [0002] As the pace of urban life continues to accelerate, people increasingly use various types of fast food to solve the problem of "food". The existing self-service pricing systems on the market have chips or barcodes on the plates, but these methods are costly and are easily affected by washing, temperature and other environments. [0003] In a word, there are following problems in existing fast food: [0004] 1) There are often long queues at checkout, resulting in low efficiency; [0005] 2) Settlement personnel are in a hurry, making mistakes and making customers dissatisfied. Contents of the invention [0006] Aiming at the defects existing in the prior art, the object of the present invention is to provide a color recognition-based automatic p...
