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 an automatic pricing method and system for dinner plates based on color discrimination. The method includes the steps that first, a color sensor collects the colors of the bottom faces of the dinner plates and then sending color signals to a single chip microcomputer; then, the single chip microcomputer figures out the prices corresponding to different dinner plates by calculating the color signals and sends price signals to a display screen; afterwards, the display screen displays corresponding charge fees according to the received price signals. The automatic pricing method and system for the dinner plates based on color discrimination have the advantages that the color features are adopted, the color signals are collected, pricing is achieved through programs, the system is relevant to a common card swiping system, and thus popularization is easy; convenience and rapidness are achieved compared with a traditional money collecting mode, and compared with bar code pricing and chip pricing, the system is simpler, lower in cost and more flexible to use; unmanned management can be realized when the system operates, so that the system is more advanced; machine computation is more efficient, and thus more fairness is achieved.

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...
