AI Technical Summary

Problems solved by technology

[0012] After entering the application area, the peripherals of the system have to be reinitialized, which is a waste of time
[0013] To sum up, if the BootLoader program is used, the electronic transaction time will generally increase by about 20ms, and 20ms is extremely important for transaction performance, so each electronic label manufacturer does not use the BootLoader program, even if it is troublesome to update the program

Embodiment 1

[0032] The method for updating an application program using a Bootloader program in this embodiment uses a vehicle identification module (VIM) as a program storage module.

[0033] VIM is a security module for ETC electronic tags. Its main features are: 1. Record the information of the operating unit; 2. Record the vehicle information of the owner; 3. The information access conforms to the ISO-7816 standard specification and PBOC specification; 4. Information structure and The application protocol conforms to the regulations of ITSC; 5. It has the function of real anti-dismantlement, which can effectively prevent the user from moving the module to other vehicles for use.

[0034] VIMs may include embedded security modules, energy storage elements, microprocessors and trigger circuits. When the VIM is connected to the main circuit of the electronic label through the connector, the energy storage element is charged, and when the VIM is removed from the main circuit of the electr...

Embodiment 2

[0058] The electronic tags used in the national standard ETC system can not only communicate with VIM, but also read user card information. The user card is an ordinary CPU card, which also supports the ISO7816 standard and has data storage capability. Therefore, in addition to using the VIM as the program storage module in the program update method of the present invention, other embodiments of the present invention can also use the CPU card as the program storage module.

[0059] In Embodiment 2 of the present invention, the CPU card storing the application program is called a program upgrade card, and a file directory structure is set in the program upgrade card. Figure 6 It is a diagram of the file directory structure of the program upgrade card used in the application program update method using the Bootloader program in Embodiment 2 of the present invention. Such as Figure 6 As shown, the DF05 program storage directory is included in the main directory 3F00, and the ...

Abstract

The invention provides an application update method by a boot loader. The method includes: an interruption trigger signal is generated when an electronic tag is inserted into a program memory module; the interruption trigger signal triggers the boot loader to read an application in the program memory module; and the boot loader stores the read application in a memory of the electronic tag. The application update method by the boot loader causes no extra increase in transaction time.

Description

technical field [0001] The invention relates to an electronic toll collection (ETC) system, and more specifically, relates to a method for updating an application program of an electronic tag in the ETC system. Background technique [0002] In the use of electronic tags in the existing domestic ETC system, transaction speed has always been a key indicator, which is determined by the application environment. That is, the faster the transaction speed, the better, and the satisfactory transaction speed cannot be achieved in the prior art. There are many ways to improve the transaction speed of ETC electronic tags, such as the method in the free flow application: cancel the electronic wallet, and all calculations are settled in the background, which simplifies the transaction process. However, the e-wallet cannot be canceled in non-free flow applications, so in the case of limited process optimization capabilities, the method of increasing the hardware speed is generally adopte...
