Description

Technical Field

[0001] The present application relates to the technical field of signal processing, and particularly to a method for identifying a logistics object, a device for identifying a logistics object, and a system for identifying a logistics object. Background Art

[0002] In the field of logistics management, the identification information of goods is relied on in various links such as the warehousing, shipping, and transportation of goods.

[0003] Logistics management systems usually use paper waybills to record the identification information of goods. However, due to characteristics such as being easy to copy, not anti-fouling, not moisture-proof, and cumbersome to operate, paper electronic waybills affect the transportation efficiency and operating costs.

[0004] Using radio frequency identification tags (RFID) to record the identification information of goods is a new logistics transmission solution. The identification information of goods is stored in the radio frequency tags, and the radio frequency tags are attached to each good, and the identification information recorded by the radio frequency tags is read through a fixed or handheld reader.

[0005] However, the radio frequency tags have a complex structure, including a complete radio frequency chip, a storage chip, and a radio frequency circuit, and the cost is very high, more than 10 times that of paper electronic waybills, greatly increasing the costs of logistics management enterprises.

[0135] To make the above objects, features, and advantages of the present application more obvious and understandable, the present application will be further described in detail below with reference to the accompanying drawings and specific implementation manners.

[0136] Refer to Figure 1 , which shows a flowchart of the steps of the first embodiment of a method for identifying a logistics object according to the present application, wherein a metal tag is provided on the logistics object, and the method may specifically include the following steps:

[0137] Step 101, scan the metal tag to generate a scan result;

[0138] The method for identifying a logistics object according to the embodiment of the present application is applicable to identifying logistics objects in various logistics scenarios. For example, in the warehouse logistics scenario, identify the logistics objects transported on the transport equipment. During the process of a courier delivering parcels, identify the logistics objects.

[0139] The logistics object can be a shipment or a parcel. A metal label can be set on the surface of the logistics object, and the setting methods include but are not limited to spraying, printing, pasting, and stamping. The metal label can have a design of a pattern, shape, color, or a combination thereof, and by designing the metal label, the information of the logistics object can be expressed.

[0140] When scanning the logistics object, the metal label on the logistics object can be scanned. In practice, a fixed scanning device or a handheld scanning device can be used to scan the logistics object.

[0141] Step 102, determine the information of the logistics object according to the scanning result.

[0142] According to the scanning result of the metal label, determine the information of the logistics object represented by the design of the metal label.

[0143] According to the scanning result, the information of the logistics object represented by the design of the metal label can be determined.

[0144] In the embodiments of the present application, a metal label is set on the logistics object. When it is necessary to identify the logistics object, the metal label of the logistics object can be scanned to generate a scanning result; then, according to the scanning result, the information of the logistics object is determined. Since the metal label does not require any chips and electronic components, nor complex assembly means, the cost is extremely low. The method of identifying the logistics object by setting the metal label can greatly reduce the management cost of the logistics object.

[0145] Refer to Figure 2 , which shows the flowchart of the steps of the second embodiment of a logistics object identification method of the present application, where the logistics object is provided with a metal label, and the metal label has a pattern. The method may specifically include the following steps:

[0146] Step 201, scan the metal label to generate a scanning result;

[0147] The logistics object identification method of the embodiments of the present application is applicable to identifying logistics objects in various logistics scenarios. For example, in the warehouse logistics scenario, identify the logistics objects transported on the transport equipment. During the process of a courier delivering parcels, identify the logistics objects.

[0148] The logistics object can be a shipment or a parcel. A metal label can be set on the surface of the logistics object, and the setting methods include but are not limited to spraying, printing, pasting, and stamping. The metal label has a pattern, and the pattern can be composed of two colors. In order to make the scanning result clear, two colors with different shades can be used to form an identification pattern.

[0149] In one example, the dark part is made of metal or alloy, and the light part can be hollowed out or made of materials of other materials, such as paper or plastic.

[0150] In another example, the light part can be made of metal or alloy, and the dark part can be made of other materials, such as paper or plastic.

[0151] In yet another example, the dark part can be printed with a professional printer or a metal printer.

[0152] In yet another example, patterns of two shades of color can be etched on the metal.

[0153] When scanning a logistics object, a metal label on the logistics object can be scanned. In practice, a fixed scanning device or a handheld scanning device can be used to scan the metal label of the logistics object.

[0154] Step 202, identify the pattern of the metal label according to the scanning result;

[0155] The scanning result can be a scanned image generated by scanning, and the scanned image can include the pattern of the metal label. Multiple image recognition technologies can be used to identify the pattern from the scanned image. For example, machine vision recognition, image recognition model recognition, etc.

[0156] When scanning a logistics object, it is necessary to ensure that the metal label on the logistics object can be scanned. If the metal label is not scanned, the information of the logistics object cannot be determined.

[0157] Step 203, determine the information of the logistics object according to the pattern.

[0158] The pattern can contain the information of the logistics object or the corresponding coding information. For example, if the identification information of a logistics object is cosmetics, the pattern can include the word "cosmetics" or the two-dimensional code corresponding to "cosmetics" (coding information).

[0159] The pattern can also include link information associated with the information of the logistics object. After determining the link information from the pattern, the information of the logistics object can be jumped to through the link information.

[0160] In different logistics scenarios, the information of the logistics object can include different information, and the information of the logistics object can include at least one of identification information, sorting information, transfer information, packing strategy information, express delivery strategy information, and preciousness information.

[0161] In the embodiments of the present application, a metal tag with a pattern is set on the logistics object. When it is necessary to identify the logistics object, the metal tag can be scanned to generate a scanning result; then, according to the scanning result, the pattern of the metal tag is identified; after the pattern is identified, the pattern is used to determine the information of the logistics object. Since the metal tag does not require any chips and electronic components, nor complex assembly means, the cost is extremely low. The method of setting a metal tag to identify the logistics object can greatly reduce the management cost of the logistics object.

[0162] Referring to Figure 3 , a flowchart of steps of Embodiment 3 of a method for identifying a logistics object according to the present application is shown, where the logistics object is provided with a metal tag, the metal tag has a pattern, and the pattern includes a symbol pattern. The method may specifically include the following steps:

[0163] Step 301, scan the metal tag to generate a scanning result;

[0164] In practice, a user can use a fixed scanning device or a handheld scanning device to scan the metal tag of the logistics object.

[0165] The scanning device may include a camera device, a millimeter-wave scanning device, or a scanning device using a wavelength shorter than that of millimeter waves, such as a scanning device using terahertz waves.

[0166] When using a millimeter-wave scanning device, a millimeter-wave scanning device can be used to emit a pulse signal to the metal tag for scanning; the millimeter-wave scanning device uses the received pulse reflection signal for millimeter-wave imaging to obtain a scanning image.

[0167] The pulse signal is a millimeter-wave pulse signal. The frequency band range of millimeter waves is usually 30 - 300 GHz, and the corresponding wavelength ranges from 1 mm to 10 mm.

[0168] Millimeter-wave imaging technology uses a synthetic aperture imaging method, and the image resolution can reach the millimeter level, and both the signal-to-noise ratio and the contrast are relatively high. The synthetic aperture imaging technology is based on the Doppler effect. If a moving logistics object is scanned, for example, a logistics object placed on a conveyor belt is scanned, since there is a Doppler frequency shift when the logistics object moves, it will affect the accuracy of millimeter-wave imaging. Therefore, when performing millimeter-wave imaging, correction processing needs to be performed according to the movement information of the logistics object to obtain a more accurate millimeter-wave image.

[0169] In the embodiments of the present application, the movement information of the logistics object can be obtained; the millimeter-wave scanning device uses the pulse reflection signal and the movement information of the logistics object for millimeter-wave imaging to obtain a scanning image.

[0170] When using a camera device, the camera device can be used to optically scan a metal tag to obtain a scanned image.

[0171] Among them, the camera device can be a mobile terminal with a camera or an independent camera device.

[0172] In a variety of logistics scenarios, a millimeter-wave scanning device and a camera device can be used in combination to scan logistics objects. For example, when the millimeter-wave scanning device scans unstably, the camera device can be used for supplementary scanning.

[0173] Step 302: Identify the pattern of the metal tag according to the scanning result;

[0174] The scanning result can be a scanned image generated by scanning, and the scanned image may include the pattern of the metal tag. A variety of image recognition technologies can be used to identify the pattern from the scanned image. For example, machine vision recognition, image recognition model recognition, etc.

[0175] Step 303: Identify the coding information corresponding to the symbol pattern in the pattern;

[0176] The symbol pattern can be a pattern of two alternating light and dark colors distributed in a plane (two-dimensional direction) according to a certain rule using a certain specific geometric figure, or a pattern of two regions with different depths of light and dark in a three-dimensional space according to a certain rule using a certain specific geometric figure. In code compilation, the concept of the "0" and "1" bit streams that form the internal logic basis of a computer is cleverly utilized, and several geometric shapes corresponding to binary are used to represent the coding information.

[0177] The coding information is information obtained by encoding characters, numerical values, symbols, etc. according to a certain coding rule.

[0178] For example, the coding information can encode "cosmetics" into information composed of "0" and "1".

[0179] Step 304: Use the coding information to determine the information of the logistics object.

[0180] The coding information can be mapped to the information of the logistics object, or can be mapped to the link information for jumping to the information of the logistics object, or can be mapped to the associated code information associated with the coding information.

[0181] In the embodiment of the present application, step 304 may include: determining the associated code information associated with the coding information; using the associated code information to determine the information of the logistics object.

[0182] The associated code information is another encoded information associated with the encoded information, and the associated code information can be mapped to the information of the logistics object or the connection information for jumping to the information of the logistics object.

[0183] For example, the encoded information is a sub-code, and the associated code information is the main code. The pattern of the sub-code can be relatively simple, saving costs. The main code can be mapped by multiple sub-codes, that is, multiple sub-codes can be mapped to one main code.

[0184] In the embodiment of the present application, a metal label with a symbol pattern is set on the logistics object. When it is necessary to identify the logistics object, the metal label can be scanned to generate a scanning result; then the pattern is identified according to the scanning result; after the pattern is identified, the encoded information of the symbol pattern in the pattern is identified, so as to determine the information of the logistics object according to the encoded information. Since the metal label does not require any chips and electronic components, nor complex assembly means, the cost is extremely low. The method of setting a metal label to identify the logistics object can greatly reduce the management cost of the logistics object.

[0185] Refer to Figure 4 , which shows a flowchart of the steps of the fourth embodiment of a logistics object identification method of the present application, wherein the logistics object is provided with a metal label, the metal label has a pattern, and the pattern includes a positioning pattern. The method may specifically include the following steps:

[0186] Step 401, scan the metal label to generate a scanning result;

[0187] In practice, the user can use a fixed scanning device or a handheld scanning device to scan the metal label of the logistics object.

[0188] The scanning device may include a camera device, a millimeter wave scanning device, or a scanning device using a wavelength shorter than the millimeter wave wavelength, such as a scanning device using terahertz waves.

[0189] When using a millimeter wave scanning device, the millimeter wave scanning device emits a pulse signal to the metal label for scanning; the millimeter wave scanning device uses the received pulse reflection signal for millimeter wave imaging to obtain a scanning image.

[0190] In the embodiment of the present application, the movement information of the logistics object can be obtained; the millimeter wave scanning device uses the pulse reflection signal and the movement information of the logistics object for millimeter wave imaging to obtain a scanning image.

[0191] When using a camera device, the camera device can perform optical scanning on the metal label to obtain a scanning image.

[0192] Among them, the camera device can be a mobile terminal with a camera or an independent camera device.

[0193] In a variety of logistics scenarios, millimeter-wave scanning devices and camera devices can be used in combination to scan logistics objects. For example, when the millimeter-wave scanning device scans unstably, the camera device can be used for supplementary scanning.

[0194] Step 402: Identify the pattern of the metal tag according to the scanning result;

[0195] The scanning result can be a scanned image generated by scanning, and the scanned image can include the pattern of the metal tag. A variety of image recognition technologies can be used to identify the pattern from the scanned image. For example, machine vision recognition, image recognition model recognition, etc.

[0196] Step 403: Determine the position information of the positioning pattern in the pattern.

[0197] Determine the position information of the positioning pattern in the pattern, so that the position information of the logistics object can be determined according to the position information of the positioning pattern.

[0198] The positioning pattern is a pattern set for determining the position where the metal tag is located. The positioning pattern can include a plurality of sub-patterns arranged separately. The sub-patterns can be set as patterns with simple shapes and easy to identify. Such as, square, circle, triangle, etc.

[0199] In the embodiments of the present application, in the embodiments of the present application, a metal tag with a positioning pattern is set on the logistics object. When it is necessary to identify the logistics object, the metal tag can be scanned to generate a scanning result; then the pattern is identified according to the scanning result; after the pattern is identified, the position of the positioning pattern in the pattern is determined, so that the position information of the logistics object can be determined. Since the metal tag does not require any chips and electronic components, nor complex assembly means, the cost is extremely low. The method of setting a metal tag to identify the logistics object can greatly reduce the management cost of the logistics object.

[0200] In the embodiments of the present application, after determining the position information of the positioning pattern, in addition to determining the position information of the logistics object, the position information of the positioning pattern can also be used to adjust the scanning area. Thus, the logistics object can be scanned again in the adjusted scanning area to increase the scanning accuracy.

[0201] When using a millimeter-wave scanning device, the position information of the positioning pattern can be used to move the signal emission position of the millimeter-wave scanning device towards the positioning pattern; or, the position information of the positioning pattern can be used to focus the pulse signal emitted by the millimeter-wave scanning device towards the positioning pattern.

[0202] Specifically, the signal emission position of the handheld millimeter-wave scanning device is set inside the device. If the handheld millimeter-wave scanning device is used, the handheld millimeter-wave scanning device can be moved towards the positioning pattern, making the signal emission position closer to the metal tag, thereby scanning the metal tag more accurately.

[0203] The signal emission position of the fixed millimeter-wave scanning device is an external millimeter-wave antenna. If the fixed millimeter-wave scanning device is used, the millimeter-wave antenna can be moved towards the positioning pattern, making the millimeter-wave antenna closer to the metal tag, thereby scanning the metal tag more accurately.

[0204] By adjusting the phase of the antenna of the millimeter-wave scanning device to adjust the aggregation position of the pulse signal, the emitted pulse signal can be made to aggregate towards the positioning pattern.

[0205] Referring to Figure 5 , a flowchart of the steps of Embodiment 5 of a method for identifying a logistics object according to the present application is shown. The logistics object is provided with a metal tag, and the metal tag has a pattern. The method may specifically include the following steps:

[0206] Step 501, perform a first scan on the metal tag to generate a first scan result;

[0207] The logistics object may be a shipment, a parcel. A metal tag may be provided on the surface of the logistics object, and the setting methods include but are not limited to spraying, printing, pasting, and stamping. The metal tag may have a design of a pattern, shape, color, or a combination thereof. By designing the metal tag, the information of the logistics object can be expressed.

[0208] The first scan may be performed within a relatively large scan range, and the purpose is to ensure that the metal tag can be scanned.

[0209] A scanning device may be used to perform a first scan on the metal tag of the logistics object to generate a first scan result.

[0210] The scanning device may include a camera device, a millimeter-wave scanning device, or a scanning device using a wavelength shorter than the millimeter-wave wavelength, such as a scanning device using terahertz waves.

[0211] Step 502, according to the first scan result, perform a second scan on the metal tag to generate a second scan result;

[0212] The purpose of the second scan is to scan the metal tag more precisely. Based on the first scan result, a second scan is performed on the metal tag according to the first scan result to generate a second scan result.

[0213] Step 503, determine the information of the logistics object according to the second scan result.

[0214] Based on the scanning result of the metal tag, determine the information of the logistics object represented by the design of the metal tag.

[0215] The scanning result can be a scanned image, and based on the scanned image, the information of the logistics object represented by the design of the metal tag can be determined.

[0216] In the embodiments of the present application, a metal tag is set on the logistics object. When it is necessary to identify the logistics object, the metal tag of the logistics object can be first scanned to ensure that the metal tag is scanned. Then, based on the first scanning result obtained from the first scan, the metal tag is more accurately second-scanned to obtain a second scanning result, and then the information of the logistics object is determined according to the second scanning result. Since the metal tag does not require any chips and electronic components, nor complex assembly means, and the cost is extremely low, the method of setting a metal tag to identify the logistics object can greatly reduce the management cost of the logistics object.

[0217] Refer to Figure 6 , which shows a flowchart of the steps of the sixth embodiment of a method for identifying a logistics object according to the present application, wherein the logistics object is provided with a metal tag, and the metal tag has a pattern. The method may specifically include the following steps:

[0218] Step 601, perform a first scan on the metal tag to generate a first scanning result;

[0219] The first scan can be performed within a relatively large scanning range, and its purpose is to ensure that the metal tag can be scanned.

[0220] A scanning device can be used to perform a first scan on the metal tag of the logistics object to generate a first scanning result.

[0221] The scanning device can include a camera device, a millimeter-wave scanning device, or a scanning device using a wavelength shorter than that of millimeter waves, such as a scanning device using terahertz waves.

[0222] In the embodiments of the present application, step 601 may include: emitting a pulse signal to the metal tag by a millimeter-wave scanning device; performing millimeter-wave imaging by the millimeter-wave scanning device using the received pulse reflection signal to obtain a first scanned image.

[0223] Step 602, identify the pattern of the metal tag according to the first scanning result;

[0224] The first scanning result can be a first scanned image generated by scanning, and the first scanned image may include the pattern of the metal tag. A variety of image recognition technologies can be used to identify the pattern from the first scanned image. For example, machine vision recognition, image recognition model recognition, etc.

[0225] Step 603: Use the pattern of the metal tag recognized according to the first scan result to perform a second scan on the metal tag to generate a second scan result;

[0226] In order to more accurately identify the information of the logistics object from the image, the scanning area can be adjusted according to the pattern of the metal tag obtained by the first scan, and then a second scan is performed on the logistics object to generate a second scan result.

[0227] In the embodiment of the present application, the pattern in the metal tag may include a positioning pattern. The pattern of the metal tag as a whole is square, and the positioning pattern is composed of patterns provided at three corners of the large square, and the identification pattern is a symbol pattern composed of black and white dots.

[0228] Of course, in practice, the pattern of the metal tag is not limited to a square, and it can also be other shapes. The positioning pattern is not limited to being located at the corners of the overall pattern, and the identification pattern is not limited to a symbol pattern. Those skilled in the art can design the positioning pattern and the identification pattern according to actual needs, and the present application does not make any limitations in this regard.

[0229] In an example of the embodiment of the present application, when using a millimeter-wave scanning device for scanning, step 603 may include the following sub-steps:

[0230] Sub-step S11: Determine the position information of the positioning pattern in the pattern of the metal tag recognized according to the first scan result;

[0231] Sub-step S12: Use the position information of the positioning pattern to adjust the scanning area of the millimeter-wave scanning device;

[0232] The second scan process can be performed within a smaller scanning range, and its purpose is to scan the metal tag more accurately. The scanning range can be adjusted according to the position information of the positioning pattern so that the scanning range is more concentrated on the positioning pattern.

[0233] Specifically, the position information of the positioning pattern can be used to move the signal emission position of the millimeter-wave scanning device towards the positioning pattern; or, the position information of the metal tag can be used to concentrate the pulse signal emitted by the millimeter-wave scanning device towards the positioning pattern.

[0234] Sub-step S13: Use the millimeter-wave scanning device to perform millimeter-wave imaging on the received pulse reflection signal after the scanning area is adjusted to obtain a second scan image.

[0235] Step 604: Identify the pattern of the metal tag according to the second scan result;

[0236] The second scan result may be a second scan image generated by the scan, and the pattern of the metal tag may be included in the second scan image. A variety of image recognition technologies can be used to recognize the pattern from the second scan image. For example, machine vision recognition, image recognition model recognition, etc.

[0237] Step 605: Use the pattern of the metal tag recognized according to the second scan result to determine the information of the logistics object.

[0238] In the embodiment of the present application, the pattern may include a code element pattern, and step 605 may include the following sub-steps:

[0239] Sub-step S21: In the pattern of the metal tag recognized according to the second scan result, recognize the encoded information corresponding to the code element pattern;

[0240] Sub-step S22: Use the encoded information to determine the information of the logistics object.

[0241] Specifically, sub-step S22 may include: determining the associated code information associated with the encoded information; using the associated code information to determine the information of the logistics object.

[0242] In the embodiment of the present application, a metal tag with a pattern is set on the logistics object. When it is necessary to identify the logistics object, the metal tag can be scanned for the first time to ensure that the metal tag is scanned. Then, according to the first scan result obtained from the first scan, the metal tag is scanned more accurately for the second time to obtain the second scan result. Then, the pattern of the metal tag is recognized from the second scan result, and the information of the logistics object is determined according to the pattern of the metal tag. Since the metal tag does not require any chips and electronic components, nor complex assembly means, the cost is extremely low. The method of setting the metal tag to identify the logistics object can greatly reduce the management cost of the logistics object.

[0243] Refer to Figure 7 FIG. is a schematic diagram of a logistics object identification system for applying the logistics object identification method of the embodiment of the present application. Among them, the logistics object identification system may include a fixed millimeter wave scanning device, a server, and a transmission device.

[0244] Each logistics object is provided with a metal tag, and the metal tag includes a code element pattern and a positioning pattern.

[0245] The fixed millimeter wave scanning device includes a millimeter wave signal processing host and a millimeter wave antenna array. The transmitting end of the millimeter wave antenna array points to the transmission device, and the millimeter wave signal processing host emits a pulse signal through the millimeter wave antenna array.

[0246] The logistics object is placed on the transmission device for transmission. When the metal tag enters the scanning range, the pulse signal is reflected by the metal tag and returns to the millimeter-wave antenna array, and the pulse reflection signal is received by the millimeter-wave antenna array.

[0247] After that, the millimeter-wave signal processing host can generate a millimeter-wave image using the pulse reflection signal, or the millimeter-wave signal processing host can send the pulse reflection signal to the server, and the server can generate a millimeter-wave image using the pulse reflection signal.

[0248] When generating the millimeter-wave image, correction needs to be performed according to the speed information and direction information of the logistics object.

[0249] The speed information and direction information of the logistics object can be detected by a moving speed sensor set on the transmission device. The moving speed sensor can send the speed information and direction information to the millimeter-wave signal processing host or the server. Among them, the transmission speed and transmission direction of the transmission device can be controlled by the server or manually configured.

[0250] After the millimeter-wave signal processing host generates a millimeter-wave image or the server generates a millimeter-wave image, the server can identify the positioning pattern from the millimeter-wave image and determine the position information of the positioning pattern. After that, the server can send the position information of the positioning pattern to the millimeter-wave signal processing host, and the millimeter-wave signal processing host adjusts the scanning area according to the position information of the positioning pattern. One way is that the millimeter-wave signal processing host controls the millimeter-wave antenna array to move or rotate towards the position of the positioning pattern; another way is that the millimeter-wave signal processing host adjusts the phase of the millimeter-wave antenna array so that the pulse signal emitted by the millimeter-wave antenna array converges towards the positioning pattern.

[0251] The millimeter-wave antenna array receives the pulse reflection signal obtained after the scanning area is adjusted. The millimeter-wave signal processing host can perform imaging processing again according to the pulse reflection signal to obtain a millimeter-wave image; or the server can perform imaging processing again according to the pulse reflection signal to obtain a millimeter-wave image.

[0252] Finally, the server identifies the symbol pattern from the second obtained millimeter-wave image, so that the identification information of the logistics object can be determined according to the symbol pattern.

[0253] Refer to Figure 8 , which shows a step flow chart of an embodiment of an object recognition method of the present application, where the object is provided with a metal tag, and the method may specifically include the following steps:

[0254] Step 901, identify the metal tag and obtain the recognition result;

[0255] The object can be an actual object in reality. In daily life, people hope to know the information of the objects they observe and touch, or obtain information related to the objects.

[0256] In the embodiments of the present application, a metal tag can be set on the object, and the setting methods include but are not limited to spraying, printing, pasting, and stamping. By setting a metal tag on the object, people can obtain the information of the object.

[0257] For example, when scanning at the cashier, the metal tag is scanned to obtain payment information. When riding a shared bicycle, the metal tag set on the shared bicycle is scanned to unlock the shared bicycle.

[0258] Step 902, determine the information of the object according to the recognition result.

[0259] According to the scanning result of the metal tag, determine the information of the object represented by the design of the metal tag.

[0260] The scanning result can be a scanned image, and the information of the object represented by the design of the metal tag can be determined through the scanned image.

[0261] For the object recognition method in the embodiments of the present application, specifically, reference can be made to the aforementioned object recognition method for logistics objects, which will not be elaborated here.

[0262] In the embodiments of the present application, a metal tag is set on the object. When the object needs to be recognized, the metal tag of the object can be scanned to generate a scanning result; then, according to the scanning result, the information of the object is determined. Since the metal tag does not require any chips and electronic components, nor complex assembly means, the cost is extremely low. The method of setting a metal tag to recognize the object can greatly reduce the management cost of the object.
