Description of the Invention: [Technical Field of the Invention] A method for inspecting a wafer serial number, and more particularly to a method of using a data gateway to read a wafer serial number and verify it. [Prior Art] Please refer to FIG. 1, FIG. 2, FIG. A and FIG. 3B simultaneously, which is an authentication system architecture in which the prior art uses a wafer key to start the engine. The prior art authentication system architectures are quite similar. 〇• As shown in Fig. 1, when the ignition switch module 2 senses a wafer key la insertion '. or the ignition key of the ignition switch module 2a is triggered after the wafer key la is inserted, the ignition switch module 2a requests the engine to start the authentication computer. 3 Perform crystal certification. The central processor 31 activates the wireless transceiver 33 to issue a synchronization signal that is transmitted wirelessly via the inductive module 34 connected to the wireless transceiver 33. The Transponder Chip 11 stores a Transponder ID and a Transponder Identification Code corresponding to the identification ❹ wafer 11. When the identification wafer 11 is within the sensing range of the signal transceiving of the sensing module 34, the identification wafer 11 senses the 'synchronization signal and an excitation effect is driven to transmit the above-described wafer serial number. The wireless transceiver 33 receives the wafer serial number ' via the sensing module 34 for forwarding to the engine startup authentication computer 3. The central processing unit 31 outputs a mixed identification code when it is determined that the wafer serial number matches the authentication data stored in the storage unit 32. The hybrid identification code is formed by combining an arbitrary code (Rand〇m Code) and a secret 3 201035434 code (Cipher Code), and transmits the identification chip 11 through the wireless transceiver 33. The identification chip 11 acquires and analyzes the hybrid identification code, and when it is determined that the hybrid identification code is the data required to identify the wafer 11, the wafer identification code stored in the identification wafer 11 is output. The wireless transceiver 33 receives the wafer identification code through the sensing module 34 for transmission to the engine startup authentication computer 3. Engine Startup The authentication computer 3 will start the engine device when it determines that the chip identification code matches the identification code for which the authentication data was previously found. When the judgment is not met, the engine starts the authentication. 电脑 The computer 3 does not allow the engine device to start. The prior art shown in FIG. 2 is similar to FIG. 1, but the difference is that the wireless transceiver 33 is not integrated into the engine startup authentication computer 3, but is connected to and controlled by the engine startup authentication computer 3, and the wireless transceiver 33 is The engine starts to authenticate the computer 3 through the Universal Asynchronous Receiver/Transmitter (UART), the Serial 歹 式 式 式 式 Bus (Serial Peripheral Interface Bus (SPI ❹ Bus), the regional Internet bus (Local) Interconnect Network Bus (LIN Bus) or controller area network bus (Control Area • Network Bus; CAN Bus) and other architectures are interconnected. As shown in FIG. 3A and FIG. 3B, the system architecture shown in FIG. 1 and FIG. 2 is not the same as the wafer key lb is a plug-in type wafer key, and the ignition switch module 2b has a card slot for inserting a wafer key. Lb. However, the chip key is not easy to be cracked, but the car thief, such as the original factory or the repair shop personnel, copy or reserve a 4 201035434 wafer key before the delivery or repair the vehicle, and the wafer key of the startable vehicle is not All the owners are given, 'The owner will only think that he has the chip key for all the startable vehicles, and can't - it is known from other ways that the car is set with several keys, and he does not know the wafer key or backup wafer on hand. Whether the key has been replaced by another wafer key. The car thief can steal the vehicle based on its privately copied or reserved chip key. Therefore, in the case of a car thief having a pirated wafer key, it is a problem that the manufacturer should consider, only to recognize that the wafer key owned by the owner is the wafer key of the legal startable vehicle. SUMMARY OF THE INVENTION The present invention provides a method for inspecting a wafer serial number of a wafer key that is applied to a data gateway and that only recognizes that the wafer key owned by the owner is a legal startable vehicle. The technology disclosed in the present invention is a method for inspecting a wafer serial number by a data gateway (Gateway), which is based on a data reading method Q to obtain a wafer serial number, and the data reading method can be wirelessly sensed. The wafer serial number or the serial number between the authentication computer and a wireless transceiver is obtained from an engine start-up included in the automotive wafer authentication system. The data gateway verifies whether the wafer serial number is a valid wafer serial number. The method disclosed in the present invention is applied to a data gateway for inspecting a wafer serial number, and the data gateway can read the wafer serial number of the wafer key used by the current user at any time, and verify the serial number of the wafer. The serial number of the wafer stored in the data gateway is the wafer key of the owner of the wafer, and the serial number of the wafer stored therein is 5 201035434. Even if the car thief owns or uses the pirated wafer key, the wafer serial number of the pirated wafer key must not be Existing in the data gateway, the effect of identifying the wafer key owned by the owner as the wafer key of the legally actuatable vehicle can be achieved. If the month b cooperates with the relevant anti-theft device or mechanism', the car thief can't easily steal the car and avoid the financial loss of the owner. [Embodiment] In order to further understand the end point, structural features and functions of the present invention, the related embodiments and drawings are described in detail as follows: Please refer to FIG. 4, FIG. 5A, FIG. 5B, FIG. 6A and FIG. 6B, FIG. 4 is a flow chart of data gateway reading of the embodiment of the present invention, and FIG. 5A is an example of a block diagram of the data gateway 4a according to the embodiment of the present invention, which is further illustrated by the wafer authentication system of FIG.

FIG. 5C is a schematic diagram of the second suppression engine device 7 of the data gateway 4a according to the embodiment of the present invention. 6A is an example of a block diagram of the data gateway 4b of the embodiment of the present invention, which is further illustrated by the wafer authentication system of FIG. 2, and FIG. 6B is a second type of suppression engine for the data gateway of the embodiment of the present invention. Schematic diagram of device 7 startup. In this embodiment, the engine 32 of the engine 'authentication computer 3 stores at least one authentication material 50, and each of the authentication materials 50 includes an serial number (id) 51 and an identification code 52. As shown in Fig. 5A, the data gateway 4a has a storage module 42, a sensing module 34 and a microcontroller (Micro Controller Unit) 41. Storage 6 201035434 The storage module 42 pre-records more than one wafer serial number (Transp〇nderID) 421 'If the owner owns all the wafer keys of the startable vehicle and performs the data gateway device 4 certification learning (please describe later), the storage module The wafer serial number 421 recorded by the group 42 should exactly match the serial number 51 recorded by the storage unit 32. However, when the person stealing the car privately copies any of the wafer keys, the wafer number 421 recorded by the storage module 42 does not exactly match the serial number 51 recorded by the storage unit 32. The sensing module of the data gateway 4a has a signal transceiver 43, a switch 442 and an induction coil 441 (Excitation Coil). The sensing coil 441 is connected at one end to the signal transceiver 43 and at the other end to the outside of the ignition switch module 2a. The changeover switch 442 is disposed on the induction coil 441 and is controlled by the microcontroller 41 to cause the induction coil 441 to be opened or disconnected. As shown in FIG. 6A, the data gateway 4b is different from the data gateway 4a in that it does not include an inductive module, but the microcontroller 41 is directly connected between the wireless transceiver 33 and the engine startup authentication computer 3. Connect the line.

The central processing unit 31 will make the wireless The transceiver sends out a synchronization signal, which is sent by the sensing module 34. When the chip key la enters the signal sensing mode of the sensing module 34, 7 201035434 identifies that the chip ii senses the synchronization signal and generates excitation ( The chip serial number stored in the wafer key 1 is wirelessly transmitted by the ^^〇11) effect. - As shown in FIG. 5B, the microcontroller 41 of the data gateway 4a receives the notification of the ignition switch module 2, and the microcontroller 41 The switch 442 is controlled to switch 'to make the induction coil 441 form a path. The microcontroller "can be connected to the ignition switch module 2 by the following means: First, the data gateway* is connected to the vehicle network in the vehicle. (such as the controller area network 2), the data gateway 4a is connected to the ignition switch module 2a through the vehicle network. Second, the physical circuit wiring is used to directly connect the ignition switch module 2a with the data channel. The sensor coil 441 of the data gateway 4a senses the wafer serial number transmitted by the identification wafer process. The wafer serial number sensed by the induction coil 441 is received by the signal transceiver 43 and transmitted to the microcontroller 41. On the other hand, as shown in FIG. 6B, when the microcontroller 41 of the data gateway 4b receives the notification from the ignition switch module 2b, the data transfer between the wireless transceiver 〇33 and the engine activation authentication computer 3 is performed.

The data gateway device verifies whether the wafer serial number is legal (step S120). Whether the data gateway 4a or the data gateway 4b, the microcontroller 41 will acquire the wafer. sequence The wafer serial number 421 recorded by the storage module 42 is matched with each other. When the matching result is that the wafer serial number matches, the microcontroller 41 does not perform any subsequent behavior. Otherwise, the engine startup authentication computer 3 records the authentication data. This is added
