New Description: [New Technical Field] The present invention relates to a radio frequency identification (RFID) system application, and more particularly to a system for car positioning in a parking lot. • [Prior Art] * "Radio Frequency Identification System", φ is generally referred to as RFID system. The system is composed of Reader, Tag and Application System. Combined. The system uses radio frequency signals to transmit digital data wirelessly. Therefore, the radio frequency wireless identification tag can directly read and write data without contacting the RFID reader. The frequency of use can be divided into low frequency (Low-frequency; LF), high frequency (High_frequenCy; HF), ultra high frequency (UltraHightFrequency; UHF) and microwave (Microwave) 'current passive low frequency and high frequency transmission action principle is similar The electromagnetic coupling of the transformer, UHF is the form of radio wave transmission. Therefore, the RFID reader can emit a wireless signal, and all the tags in the interpretation range in the same frequency band can be read. It is not necessary to take out the RF wireless identification tag and use it. The system still contains two parts: the radio frequency identification reader (RnD read (7) and the radio frequency wireless identification tag (RFID tag or transponder Transp〇nder). The tag can be divided into active (active) and passive (power). Passive), the standard can store a variety of types of data, including a sequence of lying, configuration instructions, activity records and 6 M346014 other data. Item fasting through the antenna to receive the signal from the tag, through the radio frequency: circuit for digital The data is transmitted, decoded, and then transmitted to the computing system. The operation of the RF circuit is transmitted through the wave between the reader and the tag, and the energy of the reader is transmitted by electromagnetic waves to the standard. At the end, the tag 钿 can induce electromagnetic waves through the antenna, and then generate sufficient electric power source to supply the internal digital circuit through the conversion circuit. Therefore, the passive tag end does not need any power source to operate. In practical applications, General access control, air parcel and φ baggage identification, inductive electronic tags, document tracking management, production line Automation, "ίτ车~笞理, σ口口防假,材料管理,物流, etc., all focus on the application area identified by nXIdentification). The ambiguity of the wireless wire, such as the honeycomb money ((10) rushing _), the wireless personal assistant (pda), the _ computer, etc., can also be applied to the positioning of the car. If it is in a parking lot building, the signal from the wireless device may not be received by multiple unit towers, or the signal from multiple unit towers may not be received by the wireless device, making it difficult to determine the location based on the network solution. . It can also be difficult to use the global satellite positioning system (Gl〇bai p〇s test; GPS) mobile phone to solve the problem. The overall operation of the all-star positioning system can be divided into three parts: the space part, the ground part and In the signal part, the positioning of the All-Justun positioning system is to measure the distance by using the satellite's basic triangulation principle, the global satellite-clamping system receiving device to transmit the light signal of the radio signal, and to determine the position of the object in space by distance— Generally, the accuracy of tens of meters can be obtained, and the GPS signal is very weak and the M346014 is usually unable to find inside the parking lot building. Therefore, the global charm (4) can be adjusted in the parking lot. Even if the village lacks the location of the mine inside the building, the location of the recording device, the accuracy of the inspection may be in the parking lot environment to effectively determine the position of the car. OBJECTIVE: The RF wireless identification tag system has been proposed for use in car tracking, but • Currently, car location information is not provided with any high accuracy. For example, if the car ‘ 贝 j 田 田 进入 进入 进入 进入 进入 进入 进入 进入 进入 进入 进入 进入 进入 进入 进入 进入 进入 进入 进入 进入 进入 进入 进入 进入 进入 进入 进入 进入 进入 进入 进入 进入When the car passes through the antenna of the reader, it is marked by the side of the reader antenna, so that the car is known to pass through the entrance of the parking lot. However, the location of the car is not known because it does not know the location of the car in the parking lot and because the car can enter or leave the parking lot via another person (four) and it will not be sideways. For example, if a car enters a multi-storey parking building, the reader can enter the car to the side of the building, but there is no information about where the car is located inside the building, such as the floor on which the car is located. The location of this floor, or the car • the car is miscellaneous by Ke's unmarked exit __ parking built secret. Therefore, when this conventional RHD tracking system can retain one of the parking lot records and their approximate location, there is an effective use of accurate and accurate vehicle positioning. Fig. 1 is a structural diagram showing an example of a conventional position detection system. In the figure, the location of the forest area iG _ is set to have a paste label. Further, the active or passive wireless identification tag la_6〇k, the reader 2A, and the antenna 3 are connected in the position search area 10. The wireless identification reader 2 transmits the rewards at predetermined time intervals: #细胄(4) Field 3G, Transition 3__ Signal 8 M346014 The receivable range 14, 17 is represented by a circle. Therefore, the wireless identification tags 60a, 60b, 60c, 60d, 60e, 60f in the circle of the receivable range 14 can receive the electromagnetic wave energy and the identification information signal from the wireless identification reader 20, and the wireless identification tags 60g, 60h 60i, 60j, 60k cannot be received. Once the wireless identification tags 6a, 60b, 60c, 60d, 60e, 60f respectively send back ID information to the antenna 3 of the reader, • the antenna 30 receives the identification information signal, and then wirelessly recognizes the information from the identification information. The ID information demodulated by the extractor 20 is notified to the server 50 via, for example, a local area network (L〇cai area • netw〇rk; LAN) 40. The server 50 receives the ID information notification of the wireless identification tags 60a, 60b, 60c, 60d, 60e, 60f, and the receiving device has received the identification information signal from the antenna 30, and then can obtain the wireless identification tags 6a, 60b, 60c, 60d, 60e, 60f individually set the position of the position. 2 illustrates a basic functional block diagram of a passive wireless identification tag, which includes an antenna 61, a rectifier unit 62, a regulator unit 63, and a clock generator unit (ci0Ck generator). Unit 64, a modulating unit 65, a demodulating unit 66, a memory unit 67, and a digital logic unit (Digital 1〇gic umt) ) 68 and so on. An antenna 61 receives electromagnetic wave induced energy and transmits a tag wireless signal. A rectifier unit 62 utilizes the principle of diode forward conduction, and the sine wave sent from the reader can be rectified by half-wave/full-wave rectification to achieve detection. A regulator unit 63 is a DC voltage that produces a stable DC voltage to supply the entire tag. The one-time generator unit 64 is a reference clock for generating digital logic and memory unit operation timing for program execution such as codec or state transition. A modulation unit 65 is used when the 9 M346014 passive tag is called (four) to call, the Lin resident tag is the same, the transmitting circuit is used to transmit the 峨 to the reading (four), the ridge reading 赖 % % 愈 愈 modul ) ) ) ) ) ) ) ) ) ) 读取Device. - The demodulation unit is a modulation signal sent from the reader to restore the reader's command signal for the digital waveform to facilitate the back-end shock code and age-old _. - Note (4) Unit 67 is where the identification code is stored. - Digital logic unit 68 is the control core of the entire circuit, mainly • controlling the timing of the operation of the operation, the codec operation, and the execution of the security function. Among them, Tianlu f 61 is the receiving-electromagnetic wave signal and energy, and the electromagnetic wave signal and energy are transmitted to the rectifying unit 62 to generate the DC power supply and the synchronous clock signal. The regulator unit is generating a stable DC power to make it use the circuit, and the digital logic is used. The command touched by the element (10) is demodulated by the demodulation unit 66. 67, the illuminating unit 68 can transmit the data in the memory unit 67 via the antenna 61 through the modulating unit 65. The passive wireless identification (9) of the fine code bribes in the New Unit 67, the first identification of the mother is not the same 'may (4) to distinguish the non-wireless identification (9). _ In Figure 1, the antenna 30 reduces the transmit power to another circle 16' of the receivable range. Once the server 50 receives the information U from the wireless identification tags 6a, (9) and the receiving nfL device has received The identification of the wireless identification reader Μ and the antenna 3 e e 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 Therefore, the wireless identification ‘sign 6 〇 a 6 〇 b close to the wireless identification line receives a plurality of identification information signals, and the number of wireless identification _ receiving identification information signals away from the wireless identification antenna 30 is small. By weighting the "number of people in the sea", the accuracy of the presumed wireless antenna 3G and the 6th position M346014 can be improved. - V':, and *, in the Republic of China Patent Document (10) 565', discloses an object tracking and management system and method using radio frequency wireless identification of the standard fiber, and records that the moving object is equipped between the positions to have an identification of the object. The wireless identification tag of the information, the location is also marked by a silk-related signing that contains information about the location. A transport vehicle for moving objects is equipped with an RFID interrogation method that can detect a signal from a wireless identification tag, and an on-board processor provides the operator of the vehicle with a sense of ambiguity about the object. The processor also determines the identification of the object and provides feedback to the operator from the location of the detection and the identification of the object being moved, the location of the vehicle, and any error in the execution of the indication. In the Republic of China patent document M267550, it is disclosed that a wireless identification and positioning device has been configured to switch the antenna inductance in the antenna inductive group by scanning, and the capacitor and the frequency generator together form a resonant circuit; The circuit is connected to the antenna inductive group and the capacitor to detect an induced electromotive force generated by one of the antenna inductive groups, and the one or more radio frequency wireless Identify tags for identification and location. - In the Republic of China publication patent document 200728756, a system and method for measuring a two-dimensional position using radio frequency identification is disclosed. It is described that the position of the measuring wireless device is improved by depositing the location office in a no-face towel. . #Wireless identification devices When they enter each other's range, they check one of the confidence levels associated with each other's location information. The wireless identification device can update its location information based on location information received from other wireless identification devices having a higher degree of confidence.
