Consumable-free garbage marking method

Abstract

The invention provides a method for marking garbage, particularly garbage thrown into a garbage can. The method comprises the steps that a dot matrix character sequence is printed on the garbage bag through a mechanical needle punching method, the character sequence adopts an 80-system or higher-system coding form, so that the number of needed characters is reduced, and the printing speed is increased. The camera is used for judging the definition of the printed dot matrix characters in real time, and the size of each point, namely a hole, on the dot matrix and the distance between the points are adjusted, so that the definition is guaranteed. And meanwhile, the garbage which cannot be printed with codes, such as scattered garbage, is photographed, and the photos and the information of the thrower are used as marks to be stored in a remote server.

Description

Technical Field

[0001] The present application relates to the technical field of garbage disposal. Background Art

[0002] The speed at which human household waste is generated is alarming, and how to deal with waste has become a very important topic. Garbage classification and disposal is a common practice. But how to achieve classification? The best way is to start from the source. That is, put it out according to the category when putting it out. Spontaneous classification and disposal will inevitably become a common practice and develop a habit. But before that, restrictive measures are still needed to regulate people's disposal behavior. The present invention provides a reliable method and product for the need for restrictive measures. Summary of the invention

[0003] Under the social effect of garbage classification and treatment, the need to encode and mark garbage so that it can be tracked and traced has emerged.

[0004] The present invention uses a mechanical conical needle to punch holes to quickly mark garbage bags and large pieces of garbage in a dot matrix character format, and takes digital photos and superimposes the information of the person who puts the garbage and the time of putting it on the digital photos to mark the scattered garbage that does not meet the standards. If the thickness and color of the garbage bag allow, or if it is large garbage, a QR code or non-penetrating dot matrix characters can be printed. A multi-binary code or a QR code can also be sprayed on the garbage bag using an inkjet printer.

[0005] With the help of big data management and AI recognition, garbage disposal behavior can be reliably marked and traced, the distribution of regional garbage types and quantities can be counted, and the allocation quantity and placement of garbage bins can be planned in a coordinated manner.

[0006] After each garbage disposal, a dot matrix character sequence is printed on the garbage bag for marking; scattered garbage is marked by coding the information of the person who puts the garbage and the time of the disposal into the photo generated by taking the photo.

[0007] The invention creates a new encoding technology, which uses 80 or more visible characters to form 80-base or more base codes to reduce the number of characters that need to be printed and use as few characters as possible to mark a large amount of garbage.

[0008] For a target like a garbage bag filled with garbage, which has no rules or regularities at all, whether the garbage in the bag will leak liquid, whether the color of the garbage bag and the color of the object in the bag can make the hole array characters clearly visible, whether the thickness and color of the garbage bag are suitable for non-penetrating coding or inkjet coding, and whether the flatness is suitable for coding or inkjet coding are all ever-changing. In order to clearly mark, the present invention uses a camera to sample the coding effect in real time, compiles a closed-loop control algorithm to dynamically adapt to these goals, and installs a pressing electric mechanism to make the printing surface as flat as possible.

[0009] The present invention realizes a coding machine, which specifically implements the method of the present invention. The machine is an automatic marking machine composed of a stepper motor motion control module composed of a microprocessor, a multi-base character encoding module, a print head, a closed-loop dot matrix size control algorithm module composed of image sampling, and a communication module. It has a small size, low cost, and is easy to install in a trash can.

[0010] The printing process of this machine is controlled by a stepper motor motion control module composed of a microprocessor. The pin-type print head forms through-hole dot matrix characters in the two-dimensional plane of the X-axis and Y-axis. The focusing lens on the Z-axis produces close-range focusing, and the focal length can be fine-tuned. The mechanical print needle is telescopically controlled by the Z-axis stepper motor. The size of the hole is determined by the depth of drilling. The mechanical print needle can rotate at high speed after being telescoped into place. According to the camera sampling results, the algorithm module is used to print the dot matrix of the characters to be printed, that is, the holes, at the corresponding size and density. The characters to be printed come from the communication module or are generated incrementally.

[0011] The machine uses a camera to perform real-time analysis and adjustment on the clarity of the punching results, determining the size of the hole and the number of dot matrix rows that represent the strokes of the characters.

[0012] In order to adapt the illumination of the environment so that the camera can sample properly, it has a light detection and fill light control module.

[0013] In order to avoid harm to the human body, a human body proximity sensing module is provided. When a human body is sensed, the door control module will not open the door at the front end of the device to print.

[0014] The device is provided with a belt compaction control module, which controls the pressure rods arranged outside the device to be linked so as to facilitate punching.

[0015] It has a cleaning module, which includes a needle suction cleaning function. After printing is completed, when the camera finds that the needle is stained, it moves to a relatively clean or dry place of the target garbage or garbage bag, drills into it, and then exits at a high speed, performing multiple cleanings depending on the situation.

[0019] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0020] The description of the marking method is contained in the instructions for use of the device of the present invention, that is, the marking device.

[0021] The size of the marker is 150 (length) x 120 (width) x 72 (height) mm. It adopts a standard cube shape and metal shell structure. It has three external interfaces: an antenna connector used by the communication module, a 4-pin socket for power supply and serial communication, and an external camera interface. In addition, there are no other parts connected to the outside. It is powered by a 5V safe voltage power supply, has an SD card, is sealed and dustproof, and has extremely low standby power consumption. The outside is a metal door with automatic opening and closing capabilities. The outside of the metal door is a grid-like metal frame, so that the print head can be applied to the printed target during marking, and the printed target can be basically kept flat. In addition to the positive and negative power lines of the 4-pin socket, there are also two data communication lines, which can communicate with the equipment outside the marker body by wired communication.

[0022] The marker also has an external electric component that needs to be installed outside the marker. It is a servo motion mechanism that is used to press the garbage bag toward the printing side of the marker to keep the printing surface flat. The servo mechanism can communicate and cooperate with the marker.

[0023] The external camera is used to take full-view photos of the entire garbage bag, large garbage, and bulk garbage.

[0024] The marking machine can be driven to start marking in two cases.

[0025] The first is to receive a command from a serial port or wireless communication interface and mark according to the characters in the command.

[0026] The second is based on the induction of the light detection module. This situation is suitable for the use scenario in the trash can. When the light detection module senses that the light changes from bright to dark, it starts marking, and the printed character is the character with the value of the last printed character plus 1. The default initial configuration of the original character is the character with a value of 0.

[0027] Which drive mode to use can be configured with instructions. No matter which marking drive occurs, the diffuse reflection infrared proximity sensor, human proximity sensor module and external camera will judge the object's condition before printing, and then start marking.

[0028] After the marking starts, the built-in camera analyzes the marking effect in real time. The analysis results are used as feedback signals to adjust the depth of penetration of the mechanical needle print head in real time to determine parameters such as the dot matrix size (the size of the dot matrix is mainly to prevent liquid leakage using tension. If the dot matrix is too small, multiple rows of dot matrices can form strokes for easy identification. The spacing between the small dots on these strokes is larger at the edge and smaller at the core to prevent the entire dot, line, or even the entire character from falling off the bag), etc., so as to perform easily recognizable permanent marking on garbage bags of various different colors, thicknesses, and filled with different garbage; the coding uses dense small holes to prevent liquid leakage. The specific dot matrix size and distance between dots are selected to be maximized under the premise of leak prevention. During this marking effect analysis process, first, a character '中' is printed at the end of the printing area, that is, the right end. During the process of printing this character, the clarity of each dot is analyzed until the appropriate parameters are found before the printing of this character is completed, and then the actual marking is printed according to the parameters. After coding, a photo needs to be taken and saved so that in case the coded area is contaminated or damaged and can still be partially recognized, it can be confirmed by comparing with the picture. This invention is equipped with a specially designed mobile phone APP for scanning code recognition or visual recognition; a diffuse reflection type infrared proximity sensor is used to sense the presence of the garbage bag, that is, only when the garbage bag approaches will an action be output for coding and marking; a human proximity sensor is used to protect the approaching human body, that is, if a human body approaches, no action will be output.

[0029] In order to improve the marking speed as much as possible, enhance the recognizability as high as possible, and at the same time ensure that the code can effectively identify each generation of garbage, the coding method uses 80 characters including the numbers 0 - 9, lowercase letters a - z (excluding lowercase i and l), uppercase letters A - Z, and 20 visible ASCII characters # $ % & ( ) + ” - / < = >? @ { [ ]} \ ^ in the ASCII code table to generate an 80 -进制 code. Simple Chinese characters and other Arabic letters except numbers can also be added to form a higher -进制 code. In this way, at most 6 characters (the 6th power of 80 is 262.144 billion) can uniquely code each bag of garbage within at least one month's time period within the geographical scope of any country in the world, and the garbage within one month must have been sorted and processed. For the processing within a large urban area, 4 - character codes can meet the requirements. The dot matrix graphic method similar to the QR code is not used for marking. This is to ensure that when the garbage bag is soiled and cannot be recognized by scanning the code, the sorting personnel can identify it visually. However, QR codes can also be printed and sprayed.

Those skilled in the art may make some simple modifications, equivalent changes or modifications using the technical contents disclosed above, which all fall within the protection scope of the present invention.
