Description

Tires, including electronic devices having data structures for tire management, management methods and management systems thereof

[0001] The present invention relates to a tire including an electronic device having a data structure for managing the tire, and more particularly, to a tire including an electronic device having a data structure for managing the tire so as to easily determine whether or not new electronic modules such as sound-absorbing materials, sealants, additional materials, studs, and sensors are additionally attached to the inside of the tire structure or on the inside and outside surfaces of the tire by reading an RFID tag without accessing an online database.

[0002] In addition, the present invention relates to a tire equipped with an electronic device for monitoring the tire by easily storing and reading data in an electronic device such as an RFID, and a management method and management system thereof.

[0003]

[0004] Recently, with the increase in technological development of connected cars, autonomous vehicles, etc., RFID tires, electronic tires, and intelligent tires with electronic devices attached or inserted into the tires are being developed and sold.

[0005] Intelligent tire monitoring systems (ITMS) are technologies that enhance vehicle safety by monitoring tire condition through chips or sensors installed in tires and then relaying this information to the driver in real time. These ITMs communicate with various safety devices in the vehicle to ensure the safety of drivers and passengers, providing tire monitoring data, including those related to various devices.

[0006] These intelligent tires are designed to measure tire-related information, process the measured information, and transmit the information to the user.

[0007] And, various wireless transmission methods are being used to transmit this information.

[0008] In particular, the electronic devices installed in intelligent tires are designed with electronic chips and antennas according to the frequency and recognition distance desired by each consumer, and can acquire information transmitted at various frequencies depending on the circuit design of the receiving end.

[0009] Specifically, a device for providing data for monitoring an object is RFID (Radio Frequency Identification). Tires with RFID tags attached include a chip that stores various tire history information and an antenna for wireless communication with a reader. The chip not only stores unique tire information such as the manufacturing date, manufacturer, and product number, but also stores and updates all logistics information from the tire production process to sales. Information from the reader is stored and updated in the chip through the antenna, and the information stored in the chip is transmitted to the reader through the antenna.

[0010] Meanwhile, an ISO standard was established and published to input the ID of a tire, and the ISO standard displays the tire manufacturer number, product information, and tire serial number as a unique number for each manufacturer.

[0011] The ISO standard follows the format of GS1, an international private standards organization, and displays unique numbers in binary.

[0012] However, despite these standards, the storage method and data management method of the memory area where the tire ID is stored vary by manufacturer and customer.

[0013] Accordingly, a technology is needed to independently read and store information about tires stored in memory.

[0014] Additionally, because in the past, access to an online database was required to obtain information about tires, there was also the problem of difficulty in reading tire information in places with poor Internet access.

[0015] US 09177183 B2 'Method for reading data stored in an electronic device for a tire' describes a method for reading data stored in the memory of an electronic device included in a tire, a memory including a data storage area having a field reserved for the tire serial number, and a method for storing the serial number in bit form. To this end, at least two allocated areas are required in the stored area to decode the tire serial number, a process is required to convert binary numbers in the allocated areas to decimal numbers, and a process is required in one of the areas to convert the decimal numbers to characters. Therefore, in order to generate a serial number, a process is required to divide the area where the serial number is stored into at least two areas, process data fetched from the areas, convert them to decimal numbers, and match them with characters.

[0016] Korean Patent Registration No. 10-2490773, 'System and method for monitoring damage to pneumatic tires using RFID tags', relates to a system and method for monitoring damage to pneumatic tires using RFID tags, which stores impact applied to the tire while the vehicle is driving in an RFID tag, thereby enabling the detection of damage to the pneumatic tire in advance. The system for monitoring damage to pneumatic tires using RFID tags according to the present invention comprises: a pneumatic tire; a shock sensor mounted inside the pneumatic tire and detecting impact input to the pneumatic tire; and an RFID tag storing impact information detected by the shock sensor.

[0017] EPC memory for RFID is typically defined by the ISO20910 standard, SGTIN96. While this method makes it easy to infer tire manufacturers, product numbers, and serial numbers, it presents the problem of each manufacturer having a different data structure.

[0025] The technical problems to be solved by the present invention are not limited to the technical problems mentioned above, and other technical problems not mentioned can be clearly understood by a person having ordinary skill in the technical field to which the present invention belongs from the description below.

[0026]

[0028] In an embodiment of the present invention, the EPC memory unit may be divided into four memories, and at least one memory may be characterized as having a memory configured as a variable memory.

[0029] In an embodiment of the present invention, the EPC memory unit may be characterized in that at least one of the four divided memories includes a serial number.

[0031] In an embodiment of the present invention, the memory including the serial number may be characterized in that the number of digits of product information distinguishing the Company prefix and the memory size of the product information is composed of 3 bits and is expressed in binary.

[0032] In an embodiment of the present invention, the memory including the serial number may be characterized by having an area capable of displaying additional information of the tire.

[0033] In an embodiment of the present invention, the additional information of the tire may be characterized by including at least one of new electronic modules such as sound-absorbing materials, sealants, studs, additional materials, and sensors additionally attached to the inside of the tire structure or on the inner and outer surfaces of the tire.

[0034] In an embodiment of the present invention, the memory including the serial number may be characterized in that it configures the presence or absence of additional information of the tire as 1 bit and is expressed in binary.

[0035] In an embodiment of the present invention, the memory including the serial number may be arranged to sequentially display the number of digits of the product information expressed in binary, the presence or absence of additional information of the tire, and the serial number from left to right.

[0036] In an embodiment of the present invention, when reading binary data stored in a memory including the serial number as decimal data, first, the number of digits of the product information is determined using 3 bits in order from the left, and the remaining bits are divided into 3 memories excluding the first memory consisting of a header, a filter value, and a partition among the 4 divided memories of the EPC memory section, and restored and displayed in the form of a decimal number or a combination of a decimal number and a character.

[0037] In an embodiment of the present invention, the electronic device may be characterized as being an RFID tag, a transponder, or a TMS sensor.

[0038] In an embodiment of the present invention, a method for managing a tire including an electronic device may be provided, including a step (s100) of inputting information of an electronic device; and a step (s200) of reading information of the electronic device, wherein the step s100 includes a step (s110) of inputting, by an input unit, continuous numbers or letters, or numbers and letters mixed together, consisting of the manufacturer information, the product information, and the serial number information, and a step (s120) of converting, by a conversion unit, the manufacturer information, the product information, and the serial number information, starting from the first column on the left, into binary numbers, and a step (s130) of inputting the classified manufacturer information, the product information, and the serial number information into respective memories.

[0039] In an embodiment of the present invention, the step s200 may be characterized by including a step of converting the memory information into a decimal number (s210), a step of converting it into manufacturer information (s220), a step of converting it into product information (s230), and a step of converting it into serial number information (s240).

[0040] In an embodiment of the present invention, in the step s120, if the serial number information is less than 12 digits, it may be characterized by inputting 0 from the left to convert it into 12 digits. In an embodiment of the present invention, a tire management system including an electronic device mounted on a tire; an input and reading device having an input unit for inputting information of the electronic device and a reading unit for reading information of the electronic device; and a display module for displaying output information; wherein the electronic device has a 96-bit memory, the memory unit is divided into four memories, and the reading unit converts the information of the memory into a decimal number by a conversion unit and converts it into manufacturer information, product information, and serial number information to generate output information can be provided.

[0041]

[0042] The effect of the present invention according to the above configuration is that the presence or absence of new electronic modules such as sound-absorbing materials, sealants, studs, additional materials, sensors, etc. additionally attached to the inside of the tire structure or on the inner or outer surface of the tire can be easily determined by reading an RFID tag without accessing an online database.

[0043] In addition, intelligent tires, which are tires that monitor the condition of the tire by attaching sensors inside the tire and estimate and provide various information such as tire load, wear, pressure, and temperature, have been developed recently, and sealant tires that automatically fill and restore the puncture area when a puncture occurs on the tire tread have been released.

[0044] In addition, the demand and production of tires with sound-absorbing materials have recently increased due to their noise reduction and resonance reduction effects. Furthermore, tires with sensors and sound-absorbing materials attached simultaneously, or with sound-absorbing materials and sealants, have been released. However, in the past, it was difficult to individually check whether various materials, studs, sensors, and other electronic modules and sound-absorbing materials were attached to the inside of the tire. However, according to the present invention, there is an advantage in that the presence of such materials, studs, sensors, and other electronic modules and sound-absorbing materials attached to the tire can be easily determined without individually checking them.

[0045] In addition, according to the present invention, when tire storage data for each customer is different, data management can be made easier by identifying, restoring, and displaying the input data structure through the product code of the tire ID.

[0046] In addition, according to the present invention, by inputting the digit information of the third memory into a part of S4, which is a fixed bit area in the SGTIN96 method of the ISO20910 standard, variable S2 and S3 areas can be determined, so that it is expected that data can be more easily managed in electronic devices such as RFID.

[0047] The effects of the present invention are not limited to the effects described above, and should be understood to include all effects that can be inferred from the detailed description of the present invention or the composition of the invention described in the claims.

[0063] The terminology used herein is merely used to describe specific embodiments and is not intended to limit the present invention. The singular expression includes the plural expression unless the context clearly indicates otherwise. In this specification, it should be understood that the terms "comprises" or "has" indicate the presence of a feature, number, step, operation, component, part, or combination thereof described in the specification, but do not exclude in advance the possibility of the presence or addition of one or more other features, numbers, steps, operations, components, parts, or combinations thereof.

[0066] Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings.

[0067]

[0068] Figure 1 is an exemplary diagram showing the attachment location of an electronic device according to one embodiment of the present invention.

[0069] Referring to FIG. 1, a tire (1) according to the present invention can be provided to have a first point (110) where a bead wire and a bead wire rubber meet, a second point (120) which is the end of a bead filler, and a third point (130) which is the end of a carcass and a belt.

[0070] In addition, the electronic device (100) may be arranged to be positioned between the first point (110) and the second point (120) or between the second point (120) and the third point (130).

[0071] Specifically, when the electronic device (100) is positioned between the first point (110) and the second point (120), it may be arranged to be positioned at a point that is 10 to 80% of the length from the first point (120) as a starting point to the second point (120).

[0072] When the electronic device (100) is positioned between the second point (120) and the third point (130), it may be positioned at a point that is 15 to 95% of the length from the second point (120) to the third point (130).

[0073] Alternatively, the electronic device (100) may be attached or inserted into the side wall and may be provided in a range between the first point (110), which is the end of the bead wire, and the third point (130), which is the end of the second belt, at a point 40 mm away.

[0074] Additionally, the electronic device (100) may be positioned within a radius of 40 mm to 60 mm from the center of the bead wire.

[0075] Meanwhile, the shape of the electronic device (100) is not limited, but may be provided in a form having at least one side of a polygon. In this case, the electronic device (100) may be provided in a plate shape, so that the attachment is performed so that the flat portion of the electronic device (100) and the inner liner are in parallel contact. The present invention provided in this manner can further reduce the risk of damage to the electronic device (100) and improve attachment stability.

[0076] For example, the electronic device (100) may be provided as a plate-shaped RFID having a total length of 30 to 150 mm, a width of 0.2 to 15 mm, and a thickness of 0.2 to 15 mm. However, the external specifications of the electronic device (100) are not limited thereto.

[0077] Additionally, depending on the location where the electronic device (100) is installed, the conditions under which it is topped, or the conditions under which it is embedded in the tire, the reception frequency may be lowered compared to the transmission frequency.

[0078] Accordingly, the dielectric constant from the attachment location of the semi-finished product to the receiving device (150) can be derived, and the transmission frequency of the electronic device (100) can be designed using the dielectric constant as a variable.

[0079] Specifically, the measurement position of the dielectric constant may be characterized as the dielectric constant at the position where the straight line intersects the tire, excluding air, when the installation positions of the electronic device (100) and the receiving device (150) are drawn in a straight line.

[0080] More specifically, the receiving device (150) may be provided at a position of 1 mm to 1500 mm from the sidewall surface of the tire, and may be provided to measure and derive the dielectric constant considering the thickness at the vertical position where the electronic device (100) and the rubber interface meet.

[0081] That is, in the present invention, it can be arranged to measure and derive the dielectric constant affected by obstacles located between the electronic device (100) and the receiving device (150).

[0082] In addition, the electronic device (100) may be designed to transmit a value obtained by multiplying the reception frequency measured by the receiving device (150) by the square root of the derived permittivity.

[0083] In addition, the receiving device (150) may be further provided to select information by determining whether the receiving frequency falls within a preset error range from the target receiving frequency.

[0084] Specifically, the receiving device (150) may be arranged to first compare, when a frequency is received, whether the received reception frequency falls within a preset error range with the target reception frequency.

[0085] In addition, when the reception frequency is outside the target reception frequency and the preset error range, the information received when the reception frequency is outside the target reception frequency and the preset error range may be arranged to be discarded without being used.

[0086] That is, the receiving device (150) may be arranged to obtain only information corresponding to a reception frequency within a preset error range, and then analyze the information to provide the user with necessary information.

[0087] The present invention, thus prepared, can further improve the reliability of information provided to users because it can minimize the possibility of information being modulated according to frequency.

[0088] FIG. 2 is an exemplary diagram of an electronic device according to an embodiment of the present invention, and FIG. 3 is an exemplary diagram of a configuration of a fourth memory according to an embodiment of the present invention.

[0089] Referring to FIGS. 2 and 3, the electronic device (100) may include a substrate portion (141), an antenna portion (142), a user memory (143), and an EPC memory portion (144).

[0090] The above substrate portion (141) may be provided as a PCB substrate and may be provided so that electronic chips and circuits are formed.

[0091] The above substrate (141) can be prepared by a single material of polymer such as epoxy or a combination of various polymers such as a synthetic resin of epoxy and phenol.

[0092] The above antenna unit (142) is provided to enable unidirectional or bidirectional transmission and reception of data, and may be provided to generate power. In addition, the antenna unit (142) may be embedded in and combined with the substrate unit (141), or may be provided as an integral part through printing, pasting, or connecting operations.

[0093] In addition, a coating material may be applied on the antenna portion (142) for protection and adhesive bonding, and the coating material may be formed of a single polymer such as epoxy or a combination of two or more polymers.

[0094] The above user memory (143) is formed on the substrate (141) and can be provided so that various data can be freely stored by manufacturer and customer.

[0095] The above EPC memory unit (144) can be arranged to store tire-related data including tire ID in multiple parts and to store the product serial number part in multiple parts.

[0096] Specifically, the EPC memory unit (144) is formed on the substrate unit (141), and may be configured to record and read data, and may be configured to consist of a total of 96 bits or more. More specifically, the EPC memory unit (144) may be configured to be 96 bits or more and 1,000 bits or less. However, the number of bits of the EPC memory unit (144) is not limited thereto.

[0097] In the embodiment of the present invention, the EPC memory unit (144) is set to 96 bits according to SGTIN96 defined by the ISO20910 standard, and this will be explained as an example.

[0098] The above EPC memory unit (144) may be divided into multiple parts to store data, and may be provided with multiple memories that can specifically divide and store the product serial number part. For example, the EPC memory unit (144) may include a first memory (145), a second memory (146), a third memory (147), and a fourth memory (148) that can divide the product serial number part and record the presence or absence of sound-absorbing material.

[0099] That is, the EPC memory unit may be characterized by being divided into four memories, at least one of which is configured as a variable memory, and further, it is preferable that at least one of the four divided memories includes a serial number.

[0100] Specifically, the first memory (145) is divided into 14 bits and can be configured with a header, a filter value, and a partition.

[0101] The above second memory (146) may be divided into 20 to 40 bits and configured to store a company prefix. The company prefix may include manufacturer information, etc., and may be expressed in decimal.

[0102] That is, the memory containing the serial number is configured to distinguish between the Company prefix and the memory size of the product information, and more specifically, the number of digits of the product information distinguishing between the Company prefix and the memory size of the product information is configured as 3 bits and can be characterized by being expressed in binary.

[0103] Meanwhile, the memory including the serial number has an area capable of displaying additional information of the tire, and the additional information of the tire may include at least one of new electronic modules such as sound-absorbing materials, sealants, studs, additional materials, and sensors additionally attached to the inside of the tire structure or on the inner and outer surfaces of the tire.

[0104] In addition, the memory containing the serial number may be configured to indicate the presence or absence of additional information of the tire as 1 bit and may be expressed in binary, and may be formed to display the number of digits of the product information expressed in binary, the presence or absence of additional information of the tire, and the serial number in order from left to right.

[0105] That is, the third memory (147) may be divided into 4 to 24 bits, and may be arranged so that product information is displayed in decimal with 1 to 7 digits. The product information may include information such as tire dimensions and types.

[0106] The total bits of the second memory (146) and the third memory (147) can be variably arranged to be 44 bits.

[0107] The above fourth memory (148) can be divided into 38 bits and arranged to display a serial number.

[0108] In addition, the fourth memory (148) may be provided to distinguish between the Company prefix and the memory size of the product information, and to further display the presence or absence of sound-absorbing tires.

[0109] Specifically, the fourth memory (148) may include a 4-1 memory (148a), a 4-1 memory (148b), and a 4-3 memory (148c).

[0110] The above 4-1 memory (148a) is composed of 3 bits and can be arranged to display the number of digits of product information in binary.

[0111] The above 4-2 memory (148b) is composed of 1 bit and can be arranged to indicate whether or not a sound-absorbing material is attached in binary.

[0112] The above 4-3 memory (148c) is composed of 34 bits and can be arranged to display the serial number in binary.

[0116]

[0117] For example, referring to Table 1 and Table 2, the product information in the third memory (147) is 123456, which is a 6-digit number. At this time, the 4-1 memory (148a) can read the 6-digit number of the product information by converting it into the binary number 101.

[0118] In addition, the above 4-2 memory (148b) may be arranged to display 0 when no sound-absorbing material such as foam is attached to the tire, and to display 1 when the sound-absorbing material is attached.

[0119] And, the above 4-3 memory (148c) can be arranged to display the decimal number of the serial number in binary with the remaining 34 bits.

[0120] The fourth memory (148) provided in this manner can be arranged to display the number of digits of the product information expressed in binary, whether the sound-absorbing material is attached, and the serial number in order from left to right.

[0121] Conversely, when reading binary data stored in the fourth memory (148) as decimal data, first, the number of digits of the product information of the third memory (147) may be determined using 3 bits in order from the left, and then 1 bit may be used to distinguish whether or not sound-absorbing material is attached. In addition, the remaining bits excluding 14 bits of the first memory (145) may be divided into the second memory (146), the third memory (147), and the fourth memory (148) and restored and displayed in the form of a decimal number or a combination of a decimal number and a character.

[0122] That is, when reading binary data stored in the memory containing the serial number as decimal data, first, the number of digits of the product information is determined using 3 bits in order from the left, and the remaining bits are divided into 3 memories excluding the first memory consisting of a header, filter value, and partition among the 4 divided memories of the EPC memory section, and then restored and displayed in the form of a decimal number or a combination of a decimal number and a character.

[0123] According to the present invention, the presence or absence of sound-absorbing material attached to a tire can be easily determined by reading an RFID tag, without accessing an online database. More specifically, the demand and production of tires with sound-absorbing material attached have recently increased due to their noise reduction and resonance reduction effects. However, conventional methods have been difficult to individually determine whether sound-absorbing material is attached to the inside of a tire. However, the present invention has the advantage of easily determining whether or not such sound-absorbing material is attached to a tire without having to individually check for it.

[0124] Even when other attachments or materials are included, the presence or absence of attachment can be determined by marking the items in 4-2 as 0 or 1. Attached materials, studs, sensors, electronic modules, sound-absorbing materials, etc. can be identified through the product code on the Tire ID. Since tire manufacturers operate different product codes depending on the presence, shape, and type of each attachment, combining the product code with the items in 4-2 allows for easy identification.

[0125] In addition, according to the present invention, when tire storage data for each customer is different, data management can be made easier by identifying, restoring, and displaying the input data structure through the product code of the tire ID.

[0126] The present invention, provided in this manner, can use an RFID tag, a transponder, or a TMS sensor as the electronic device, and is provided not only to distinguish sound-absorbing materials such as foam, but also to further distinguish tires with special specialties such as sealants, studs, additional materials, sensors, and electronic modules using a distinguisher.

[0127]

[0128] Figure 4 is a table illustrating the SGTIN96 method, the ISO standard for conventional tire RFID. The ISO standard was established and published to input tire IDs. This standard displays the tire manufacturer number, product information, and tire serial number as unique numbers for each manufacturer. The ISO standard follows the format of GS1, an international private standards organization, and displays the unique numbers in binary.

[0129] Figure 5 is a table explaining the information structure of the electronic device of the present invention.

[0130] The electronic device according to the present embodiment may be an RFID (Radio Frequency IDentification).

[0131] When RFID is used as an electronic device, the RFID can be installed by being attached to the surface of the inner liner of the tire or inserted between each semi-finished product of the tire.

[0132] And, RFID can have 96 bits of memory.

[0133] Memory of 96 bits or more can be divided into first memory, second memory, third memory, and fourth memory.

[0134] At this time, the first memory can store data declaring the SG-TIN96 format, such as a 14-bit header, filter value, and partition information.

[0135] Additionally, the second memory can store manufacturer information (Company prefix / code) of 24 bits or more.

[0136] Additionally, the third memory can store product information (Item code) of 20 bits or more.

[0137] Additionally, the fourth memory can store serial number information of 38 bits or more.

[0138] Here, the electronic device (100) may be an RFID tag, a transponder, or a TMS sensor. Furthermore, each of the header, filter value, and partition data may be data declaring the SG-TIN96 format. The same applies hereinafter.

[0139] In one embodiment illustrated in FIG. 5, a header of 8 bits, a filter value of 3 bits, a partition field of 3 bits, a company prefix of 20 bits, an item code of 24 bits, and a serial number of 38 bits are allocated from a total of 96 bits or more of memory.

[0140]

[0141] Figure 6 is an example of information input of an electronic device (RFID) of the present invention.

[0142] As shown in the table in Fig. 6, the manufacturer (Company prefix / code) information is 8808563, which is 7 digits and 24 bits in binary, the product (Item code) information is 123456, which is 6 digits and 20 bits in binary, and the serial number is 001000024586, which is 12 digits and 38 bits in binary.

[0143] In particular, the present invention sets the serial number information to 12 digits, and when the input information is less than 12 digits, it can be converted to 12 digits by inputting 0 from the left.

[0144] According to this configuration, by unifying the number of digits in the input numbers, it is expected that the different information systems of each manufacturer can be systematically unified.

[0145] The serial number information shown in the table in Figure 6 is 001000024586, and the 00 on the left corresponds to the '0's added to match the number of digits.

[0146]

[0147] FIG. 7 is a table illustrating two embodiments of the data structure of the electronic device (100) of the present invention. As described above, the second memory and the third memory are different for each manufacturer, and the embodiment of FIG. 7 (A) provides a configuration in which a portion of the fourth memory, which is a common area for all manufacturers, is allocated to an area indicating the number of digits of the third memory. As the information of the 4-1 memory determines the number of digits of the third memory, the number of digits of the second memory can also be determined according to the number of remaining bits.

[0148] As an embodiment of (B) of FIG. 7, an electronic device (100) mounted on a tire (1) having a memory of 96 bits or more, the memory being divided into four areas, wherein among the four areas, a first memory stores header, filter value, and partition data of 14 bits or more; a second memory stores manufacturer information (Company prefix) of 20 to 40 bits; a third memory stores product information of 4 to 20 bits; a fourth memory stores serial number information of 38 bits or more; and the fourth memory is divided into a 4-1 memory of 35 bits or more and a 4-2 memory of 3 bits or more, and the 4-2 memory stores data corresponding to the number of digits of data of the third memory.

[0149] In the above embodiment, the 4-2 memory is allocated to store the digit information of the 3rd memory in the last three bits of the 4th memory. Since the above area is at the very back, no identification bits are required for separate area distinction, and thus 3 bits are sufficient.

[0150]

[0151] FIG. 8 is an example of data stored in an electronic device (100) of the present invention. As shown in the first table in the example of FIG. 8, it can be confirmed that '101', which means the 6 digits of the 3rd memory, is entered in the first 3 bits of the 4-1 memory, and '0' is entered in the fourth bit to distinguish the area. The second table of FIG. 8 shows an example of inputting binary numbers according to the number of digits of the 3rd memory. In the table, it can be confirmed that 1 to 7 are expressed in binary, and '0' is entered in the fourth bit to distinguish the area.

[0152]

[0153] Additionally, the present invention also provides a method for managing a tire having an electronic device.

[0154] That is, the tire management method having an electronic device according to the present embodiment includes a step of inputting information of the electronic device (s100) and a step of reading information of the electronic device (s200).

[0155] At this time, the electronic device described above can be used.

[0156] The step (s100) of inputting information of an electronic device may include a step (s110) of inputting, by an input unit, consecutive numbers or letters, or numbers and letters mixed together, consisting of the manufacturer information, the product information, and the serial number information, a step (s120) of converting, by a conversion unit, the manufacturer information, the product information, and the serial number information into binary, starting from the first column on the left, and a step (s130) of inputting the classified manufacturer information, the product information, and the serial number information into respective memories.

[0157] The step (s200) of reading information of an electronic device may include a step (s210) of converting the memory information into decimal, a step (s220) of converting it into manufacturer information, a step (s230) of converting it into product information, and a step (s240) of converting it into serial number information.

[0158] Specifically, it may include a step (s210) of converting information from the second memory, the third memory, and the fourth memory to a decimal number, a step (s220) of returning 24 bits including the 15th bit from the left of the information as manufacturer information, a step (s230) of returning 20 bits following the 24 bits as product information, and a step (s240) of returning 38 bits following the 20 bits as serial number information.

[0159] Here, in the step (s120) where the 7 digits from the left column are classified as manufacturer information, 6 digits as product information, and the remaining digits as serial number information by the conversion unit, if the serial number information is less than 12 digits, it is preferable to convert it to 12 digits by entering 0 from the left.

[0160] According to this configuration, by unifying the number of digits in the input numbers, it is expected that the different information systems of each manufacturer can be systematically unified.

[0161]

[0162] In addition, the present invention provides a tire management method using an electronic device (100), including a step (s100) of inputting data into an electronic device (100) and a step (s200) of reading data from the electronic device (100).

[0163] The above electronic device (100) has a memory of 96 bits or more, and the memory is divided into four areas.

[0164] Among the above four areas, the first memory stores header, filter value, and partition data of 14 bits or more; the S2 area stores manufacturer information (Company prefix) of 24 bits or more; the S3 area stores product information of 20 bits or more; the S4 area stores serial number information of 38 bits or more, and the S4 area is divided into a 4-1 memory of 4 bits or more and a 4-2 memory of 34 bits or more.

[0165] The step (s100) of inputting data into the electronic device (100) includes a step (s110) of inputting continuous numbers including company information, product information, and a serial number by an input device; a step (s120) of converting manufacturer information among the continuous numbers into binary and inputting product information into an S2 area and an S3 area, respectively; a step (s130) of calculating the number of digits of the product information data; a step (s120) of inputting a binary number corresponding to the number of digits of the product information data into the first three bits of the 4-1 memory; a step (s130) of inputting '0' for area division into the last bit of the 4-1 memory; a step (s140) of generating a serial number and inputting it into the 4-2 memory; and a method for managing tires using the electronic device (100).

[0166] As described above, in the step (s120) where a binary number corresponding to the number of digits of the product information data is input into the first three bits of the 4-1 memory, and in the step (s130) where '0' for area division is input into the last bit of the 4-1 memory, the number of digits of the product information data of the 3rd memory is input in binary. It is preferable that the number of digits of the product information is a decimal number.

[0167] Afterwards, in the step (s140) where a serial number is generated and entered into the 4-2 memory, the generated serial number is entered into the 4-2 memory, which follows the 4-1 memory.

[0168]

[0169] The step (s200) of reading data from the electronic device (100) may include a step (s210) of returning the first 3 bits of the 4-1 memory to check the length of the 3rd memory; a step (s220) of checking that the data of the electronic device (100) is divided into the 2nd memory to the 4th memory excluding the 14 bits of the 1st memory; and a step (s230) of converting data to decimal according to the divided area.

[0170] According to the above configuration, the number of digits of the second memory and the third memory of different specifications for each manufacturer can be confirmed by first returning the information entered into the 4-1 memory, so it has the advantage of enabling accurate management regardless of the manufacturer.

[0171]

[0172] Figure 9 is a configuration diagram of a tire management system having an electronic device of the present invention.

[0173] As illustrated in FIG. 9, the present invention also provides a tire management system having an electronic device.

[0174] That is, the tire management system having an electronic device according to the present embodiment includes an input and reading device (200) having an electronic device (100) mounted on a tire, an input unit (210) for inputting information of the electronic device (100), and a reading unit (220) for reading information of the electronic device (100).

[0175] At this time, the electronic device may be the electronic device described above, has 96 bits of memory, and can be divided into 4 memories.

[0176] When a continuous number consisting of manufacturer information, product information, and serial number information is input into the input unit (210) of the input and reading device (200), the conversion unit (211) automatically classifies 7 digits from the first column on the left as manufacturer information, 6 digits as product information, and the remaining digits as serial number information. Thereafter, the automatically classified manufacturer information, product information, and serial number information can be input into the second memory, third memory, and fourth memory of the electronic device (100), respectively.

[0177] The reading unit (220) of the input and reading device (200) can be configured to convert information in the memory into decimal by the conversion unit (221), and convert it into the manufacturer information, product information, and serial number information to generate output information.

[0178] Specifically, information from the second memory, the third memory, and the fourth memory in the four areas corresponding to the first to fourth memories of the 96-bit information is converted to decimal, 24 bits starting from the bit including the 15th bit from the left of the information are returned as manufacturer information, 20 bits following the 24 bits are returned as product information, and 38 bits following the 20 bits are returned as serial number information, thereby generating output information.

[0179] The output information generated in this way can be displayed through the display module (230).

[0180] The input and reading device (200) can write or read information by accessing the electronic device (100) installed in the tire (1), and can be manufactured in the form of a portable, PDA-combined terminal, etc., as shown in FIG. 9.

[0181] In addition, since the display module (230) displays output information, the display module (230) may be directly installed on the input and reading device (200), or, as shown in FIG. 4, may be configured to be connected wired or wirelessly to a smartphone or other terminal to display the information.
