In addition, the present invention relates to a method for enabling a software module in an automobile measuring instrument. The invention further relates to a method for providing access to a software module used in an automobile measuring instrument. In addition, the present invention relates to a computer program containing program instructions for performing these methods. Still further, the present invention relates to an automobile measuring instrument and a memory cassette designed to be a detachable part of the automobile measuring instrument. (II) Prior art = A replaceable diagnostic instrument system is known from WO 8 9/0 6 8 39, which contains a global communication control station and at least one removable data access box. This data access box enables the control station to process data from most on-board vehicle computers. The access box contains read-only memory for storing computer programs. At least part of the programs are used to control access to data from the on-board computer. At present, the use of computers in automobiles is rapidly increasing. These computers are used to control the increasing number of automotive functions, such as engine and ignition control, airbag systems, anti-1kbrake systems, electronics Stability system, instrumentation and / or display panel, anti-theft security system, central control lock, electric windows, etc. Due to the ever-increasing functions of on-board computer control, the rapid development of electronic components for this on-board computer, and the large number of different manufacturers continue to introduce new car models in the global automotive market, installed on the current car 200410120 Different from the on-board computer, the car contains instructions for making diagnosis. The number of maintenance provided by the car service vehicle and the frequency of the access box that needs to be made. The access box must be sent frequently or alternatively to the logistics department and the new access box must be mailed to the distributor before delivery. Consequences lead to the purchase of each commercially available access box, which is the proper proper access to diagnostic instruments, including the computer connection of the program command car and this cost. These tests and verifications are, but there is one, and the number of second-hand storage computers sold is also increasing rapidly. In order to be able to cope with different service personnel, most of the access boxes are required. Each box breaking system can communicate with a specific type of car computer. For example, a car service station, such as the automobile parent trader, tends to provide auto services for some different brands. Increasing the number of service stations requires different access boxes. The new rate of containing program instructions to communicate with new car computers is increasing rapidly. Therefore, outdated program instructions are discarded, causing waste of materials and electronic components, and returning them to the factory for re-cycling (re-Cyc) led, which involves reorganization and related costs. In addition, the service market takes a long time to deliver, because when a new access box is needed, the first or diagnostic equipment manufacturer places an order, and then can receive the ordered access box delivered by services. Generally, the above & The service market for service cars is not a new and expensive access box, so buying a lot of hard-to-use products often faces the dilemma of being unable to purchase when it is needed to diagnose a special car computer box. problem. Manufacturers and diagnostic instrumentation systems currently require significant effort, such as settings or parameters that enable diagnostic instruments to communicate with an increasing number of different products, and effort and new access boxes. The total amount of all associated revenue is generated by selling new access boxes.

The server can be located, for example, at the manufacturer or at the distributor of the automobile measuring instrument, but it can also be located at any other convenient location. The server is connected to the programming device by a communication device, such as a telephone line, the Internet, or any other suitable communication device that may be known. Software modules can be accessed only when the corresponding access information is sent from the server to the programming device, thereby increasing security. In this way, the use of specific software modules can be controlled and monitored from the server. In addition, if the user is not authorized to use a specific software module, the server can lose the ability to transmit access information or can transmit invalid access information to the programming device. The user can, for example, select a function to be provided to the automobile measurement instrument from a form (t a b 1 e), an overview (0 v r r i e w), or any other selection device, such as a search function that searches for a specific function. This function may include a diagnostic function, a measurement function, a test function, or a combination of two or more of these functions. In this way, the required function can generate request information for identification function; send the request information to the server; the server generates access information in response to the request information and sends the access information to the program planning device; the program planning device At this time, the corresponding software module with the function can be accessed and the software module can be loaded into the programmable memory; steps such as this are quickly and easily provided to the automobile measuring instrument. The request information can be sent to the server via a communication device, such as the Internet, but the user can also send the request information to the server by telephone or fax. For this purpose, the server can be combined with a fax server, a voice response server, or any other inter active communication device, but it can also manually enter the information contained in the requested information. On the server. The access information can be transmitted from the server to the program planning device via the Internet, telephone network, or any other communication device. The information can also be accessed by any suitable input device, for example, by telephone and registered in the program planning device or automobile measuring instrument. The aforementioned suitable input device may be a computer keyboard that may be included in the program planning device. 200410120 included in Keyboards in automotive measuring instruments, barcodes read by barcode readers, etc. The automobile measuring instrument can be a communication device, such as a serial communication device for on-board diagnosis and / or a serial communication device for engine control unit (ECU) program planning and / or reprogramming. Advantageously, the programmable memory system is contained in a box which can be accessed and located in a vehicle measuring instrument. With this, if different boxes are connected, they can immediately provide different functions to the automobile measurement instrument. Furthermore, this can make the measuring instrument have complete availability, because if the function needs to be increased, while the second box is borrowed to provide additional functions according to the method of the present invention, the measuring instrument can still continue to use the first cassette. The foregoing only describes the case where the cassette is advantageously connected to the programming device and the method of the present invention is performed. However, an automobile measuring instrument containing programmable memory can also be connected to the programming device. The aforementioned programmable memory system is contained in the cassette. Furthermore, the programming device can also be included in the measuring instrument or advantageously in a cassette, resulting in a very simple and user-friendly set-up. Advantageously, step d) includes d 1), receiving the access information containing the access key from the server; d 2), deriving the access key from the access information; and d 3) accessing the software by the programming device using the access key Steps for modules, etc. The access key can include any suitable access device, such as a password, security code, access code, or any other suitable access device. Software modules, or libraries of different software modules, are stored in this way, for example, stored in CDR 0M, downloaded from the Internet, etc. and provided to users and can only be accessed by providing appropriate access keys. . The access key system advantageously includes a decryption (d e c r y P t i 0 η) key, and step d 3) advantageously includes the step of decrypting the software by the decryption key. In this way, the access to the software can be controlled in a very effective manner, because the software module can only be accessed after obtaining the appropriate decryption key. The method advantageously further comprises step f), by which the server charges the payment account for the user's use of the software module. In this way, the user's payment account is debited as soon as the request information is received for access to a particular function. The user then pays for the requested function. Advantageously, step f) further includes steps f. 1), checking the previous payment of the same user on the user's account database, and f. 2), determining the amount based on the previous payment. In this way, a pricing scheme can be determined by checking the previous billing amount on the same user account and determining the payment amount based on the previous billing amount. It is possible to set the amount to zero when the same function or software module has been requested and payment has been made, for example, to avoid multiple payments for the same function. In addition, 'a certain amount of discounts can be provided to users who request and pay for a given amount of functionality or software modules within a certain period of time. Advantageously, the 'request information' further includes a purpose identifier for identifying a purpose of use of the software module (de st iriation). The purpose identifier can be selected from the group consisting of user identification, measurement instrument identification, measurement instrument memory identification, and / or cassette identification. In this way, a more detailed charging mechanism (charging mechanism) can be provided because it can further perform billing and determine the amount of payment based on the history of the same purpose as the current purpose and the history of previous payments # ° In addition, the use purpose of the software module (such as the user's device, access box, etc.) can be obtained and stored in the server because it requires access to the software module. $ Θ ^ It can be stored in the server Access to the memory, so it can increase security and traceability. Advantageously, in step d), the received access information further includes a code number determined by the server-11-200410120 and step d) further includes step d5), and the password number and steps are derived from the access information. d 6), the password number is stored in the software module, and the software module further includes a password number calculation module for calculating the password number, so that the software module verifies whether the password number calculated by the password number calculation module is equal to the existence of software The password number in the module. This further prevents unauthorized use of the software. The software module includes a password number and a password number calculation module. When appropriate, for example, when the measuring instrument starts the software module, the software module first uses the password number calculation module to calculate the password number, and then compares the calculated password number with the password number stored in the software module. If the password number stored in the software module is equal to the password number calculated by the password number calculation module, the software is enabled, but if the password number provided by the password number calculation module does not correspond to the password number stored in the software The software, and therefore its functions, is not enabled. The cryptographic number calculation module is advantageously adapted to calculate a cryptographic number using at least one input parameter containing a purpose identifier. As a result, when the software module is to be used for different purposes, the password number calculation module calculates different password numbers, because the password number calculation module uses the purpose identifier as an input parameter to calculate the password number. Because different purpose identifiers generate different password numbers, the password numbers stored in the software will not correspond to the password numbers calculated by the calculation module based on different purpose identifiers, thereby preventing related functions from being used or rendering them unavailable. In this way, stolen software modules and stolen software can be avoided in various use purposes, such as various measuring instruments, cassettes, and the like. When the cryptographic digital computing module is included in the software module, different cryptographic digital computing modules can be used for a variety of software modules. Due to the correctness of the specific software module -1 2-200410120 cryptographic digital computing module system Because it is contained in each specific software module, if a third party, for example, successfully retrieves the calculation algorithm used by the cryptographic number calculation module applied to the specific software module At this time, the two of them can calculate the appropriate password numbers by various purposes and unauthorizedly store each password number in the corresponding software module to be loaded into the corresponding measuring instrument, box, etc., so as to be able to Remove the protection of password digital computing module. But 'because each software module can include different cryptographic number calculation modules using different cryptographic number calculation methods' different interpretation methods, and therefore different cryptographic number calculation modules' can be included in different software The module 'this can greatly prevent the misappropriation of various software modules', because for each specific software module providing a specific function', it is necessary to extract the number of passwords used in the calculation of the password number calculation module used in that specific software module Deduction can only be performed. The cryptographic number calculation module can perform any kind of action for computing cryptographic numbers, including logical, arithmetic, and / or any suitable type of computational action. In addition, the 'cryptographic number calculation module can use one or more input parameters, and advantageously includes a purpose identifier for identifying the use purpose of a specific software module, but any other suitable type of input parameters can be used. Advantageously, the method further comprises, before step d), providing the server with a copy number calculation tool for the server, calculating the password number in the server; and integrating the password number in the access information The steps. In this way, the cryptographic number is a duplicated cryptographic number calculation tool (having the same interpretation as the cryptographic number calculation tool included in the software module used to calculate the cryptographic number), so that once a request is received for a specific purpose of use Function -13- 200410120 The digits of the password are calculated separately and immediately. Advantageously, the software module includes: before the software module in the automobile measurement instrument is enabled, it is used to execute a password number calculation module to calculate the password number, and compare the calculated password number with the software module The password number of the software module, and the program instructions of steps such as enabling the software module only when the calculated password number is equal to the password number stored in the software module. The software module can be read from a memory device, which is advantageously selected from the group consisting of a readable optical disk, a readable magnetic disk, a readable magnetic tape, and a semiconductor memory. The software module can therefore be stored in a memory device, such as a CD ROM, for use by the user. It is advantageously stored in a secure [encrypted] form. Once a proper access information is received, a specific software module is performed. Group access. Alternatively, the software module can be downloaded from the Internet or any other computer network. The present invention further includes a method for enabling a software module in an automobile measuring instrument. The software module has been provided to the automobile measuring instrument in accordance with the method of the present invention. The method includes: Calculate the password number by the password number calculation module, compare the calculated password number with the password number stored in the software module, and enable the software module only when the calculated password number is equal to the password number stored in the software module. Enabling (enabling), and so on. In addition, the present invention provides a method for accessing a software module used by an automobile measuring instrument with programmable memory. The method includes, on a server, receiving request information from a program planning device for accessing the software module. This -14-200410120 requires that the information contains software identification for identifying the software module and sends + access information from the server to the programming device that contains the access keys that enable the vehicle measurement instrument to enable access to the software module . The computer program of the present invention contains program instructions for performing various methods of the present invention. The automobile measuring instrument of the present invention includes a programmable memory and a communication port for communication between at least the programmable memory and a program planning device having a function provided by the method of the present invention. The communication port can be a separate communication port, such as a connector for connecting cables, a wireless communication port, and the like. Advantageously, the communication port is included in a connection already provided near or on the vehicle measuring instrument, such as an electrical connector between the programmable memory and the remaining components of the vehicle measuring instrument (for example, One or more contacts). The memory cassette of the present invention is designed as a removable part of the automobile measuring instrument of the present invention and contains a programmable memory. The memory cassette is adapted to be connected with the automobile measuring instrument and become a component thereof. Enables automotive measurement instruments to access software modules. Further advantages and features of the invention will be apparent from the description of non-limiting embodiments of the invention with reference to the drawings. Fig. 1 shows an automobile measuring instrument 1 equipped with a memory case 2 containing a programmable memory. The memory shown in Figure 1 is a separate device. The body box 2 can be inserted into the appropriate slot on the car measuring instrument 1. When inserted, the post-memory box 2 is connected to the car measuring instrument through an appropriate electrical connector. 1 连接。 1 connection. In this way, when the memory cassette 2 is inserted into the slot, or alternatively is connected to the automobile measuring instrument 1 via any appropriate connector, the automobile measuring instrument 1 can read out that -15-200410120 is contained in the memory cassette 2. The contents of programmable memory. Fig. 1 also shows that the program planning device of this example includes a program station 3 connected to a personal computer 4 via an appropriate data connector. The memory box 2 containing the programmable memory can be connected to the program station, and the program station 3 can be used to delete data in the programmable memory or program the programmable memory. The personal computer 4 is connected to the server 6, such as the Internet server 6 which is quite far away from the personal computer 4 in this example. The personal computer 4 and the Internet server 6 are connected to each other via a network such as a telephone network, a personal computer network, or a public computer network of the Internet. In addition, the personal computer 4 and the Internet 6 are separately connected. It is connected to network 7 through appropriate communication links 8 a, 8 b, such as modems, data communication links, local area networks, etc. In practice, automobile measuring instruments 1, memory cassette 2, program station 3, and personal computer 4 are located in the service market, garage, car dealer, or alternatively in the service market of automobile measuring instruments or Dealer's office, but can also be located at other locations. The server 6 is typically controlled by the manufacturer of the automobile measuring instrument 1 or an authorized dealer, which enables the individual 'company or group controlling the server 6 to allow or deny the users of the program station 3 and the personal computer 4 The functions for accessing the automobile measuring instrument 1 will be described in detail below. In this example, users of program station 3 and personal computer 4 can use software modules (also known as software or software programs) from computer-readable media, such as CD-ROM 0M 5. C D-R 0 Μ 5 contains one or more functions for the automotive measuring instrument 1, these functions are incorporated or appropriate in appropriate software programs or modules. The soft system is stored in the CD-ROM 5 after being encrypted, so it needs to be decrypted before it can function.) The operation of the system of Fig. 1 will be described below with reference to Fig. 2. -16- 200410120 Figure 2 shows a flowchart containing steps 20 to 28. These steps are performed in a programming device, such as a personal computer 4, a programming station 3, or both. Fig. 2 additionally shows the steps 3 0-35 performed in the server 6 shown in Fig. 1. At step 20, the programmable memory of the automobile measuring instrument 1 is created. In this example, it is contained in the memory box 2 and the programming device. This example is the connection between the programming station 3. This can be achieved by electrically connecting the memory cassette 2 and the program station 3. In step 21, a request message is generated when the user of the personal computer 4 selects a function. This request information contains a function identifier for identifying the requested function, such as a software number, and advantageously a purpose identifier, such as a memory box number, a user number, a customer number, a measuring instrument number, or any other A suitable identifier. Next, at step 22, the request information is sent from the personal computer 4 to the server 6 via the network 7. At step 30, on the server, determine whether the request is valid. This validity determination can be performed, for example, according to the purpose identifier for use, that is, by checking the resource library in or on the server 6 to determine whether the requested information is contained in Valid intent identifier in the database. Purpose indentifier in the list. Next, at step 31, the decryption key is determined. The decryption key can depend on the function, that is, the specific software requested on the CD-ROM 5, but the decryption key can also depend on the user, the purpose of use, and the like. Next, in step 32, the number of ciphers is calculated in the server 6 by using a digit number calculating module residing in the server or accessible by the server. The functions of the cryptographic number and cryptographic number calculation module are detailed below. At step 33, the user's account is charged for the use of the requested function. Can be billed on a fixed fee basis, but can also be billed based on, for example, payments from -17- 200410120, a discount schedule, or any other appropriate parameter. At step 34, access information is generated, and the access information contains the decryption key determined at step 31 and the cipher number calculated at step 32. Next, in step 35, the access information is sent to the program planning device via the network 7. In this example, the personal computer 4 receives the access information in step 23. After receiving this access information, then the decryption key is derived from the access information in step 24, and in step 25, the requested software stored in the CD-R Ο Μ by this decryption key is in the personal computer 4 Is decrypted. In addition, at step 26, the password number is derived from the access information and at step 27 the password number is stored in the software that has been decrypted at step 25. Next, at step 28, the program station 3 loads the functions contained in the software into the programmable memory, which in this example is contained in the memory box 2. In this way, the function contained in the software can be prevented from being misused, because only users or purposes deemed valid by the server 6 will receive appropriate access information to access the software containing the function. As shown in step 40 in Fig. 3, on the automobile measuring instrument, when the function contained in the software module is requested, in step 41, the software module first calculates the password number. The calculation of the password digits uses the password digit calculation module included in the software module and at least one input parameter containing the purpose identifier (such as the serial number of the measuring instrument, the user number or the customer number, or any other identification number). Software for the purpose of executing the software). The object identifier is advantageously stored in the measuring instrument 1 and / or in the memory cassette 2. At step 42, the calculated password number is compared with the password number stored in the software. If the calculated password number is equal to the stored password number, enable the software module in step 43. If the calculated password number is not -18- 200410120 equal to the stored password number, the software module is disabled (dis ab 1 ed), that is, the availability of the function on a specific automotive measuring instrument (avai 1 abi 1 ity), the functions provided by the software module are suppressed. In this way, the software module is activated only when the correct password number is calculated, in other words, it is activated only for the intended purpose, because the password number corresponding to the stored password number is generated only for the purpose that includes the intended purpose identifier. This prevents other purposes, that is, other measuring instruments, the user from using or copying the software. Furthermore, because the cryptographic number calculation module is included in the software, different cryptographic numbers can be combined in different software modules. In this way, if an unauthorized person successfully retrieves the particular software, In the interpretation method of the specific cryptographic number calculation tool in the module, this person can only access specific software modules containing specific cryptographic number tools', and cannot access all other software modules containing different cryptographic digital calculation tools. In the above example, the software module is stored in a CD-ROM for use by the user. However, the software module can also be stored on a readable disk, a readable tape, or a semiconductor memory. Alternatively, software modules can be downloaded from the network. As a result, the present invention provides a user-friendly, fast, and safe method for providing functions to a car measurement instrument when a request for a server access function is given. Once the access request is received, the server provides access information to enable access to the software module. The aforementioned access information advantageously includes an access key, such as a decryption key. The server can determine the validity of the request and can charge the user's account to pay for the use of the software. The advantages of the system and method of the present invention are the ability to distribute the software in advance, so as to control the use of borrowed information as described above, and to start billing when access software is provided 200410120. In this way, there is no need to send large files over the Internet. Because the software containing the functions is stored in the CD-ROM in advance, only relatively few information used to provide access to the software needs to be sent over the Internet.
