Abstract

The invention provides a method and a system for carrying out wireless upgrading on firmware of a compound pass card (CPC). The method comprises the steps of initializing a system clock; initializinga wireless communication channel of the CPC; and upgrading the firmware of the CPC through the wireless communication channel. Through the method, a wireless upgrading function of the CPC can be realized, so that the upgrading of new functions of equipment is facilitated; not only one-to-one upgrading but also one-to-many upgrading can be supported, so that the upgrading speed is increased, and the man-hour cost is reduced; and the wireless upgrading method has the advantages of being reliable, stable, fast and the like.

Description

technical field [0001] The invention relates to the field of intelligent transportation, more specifically, to the field of upgrading the firmware conforming to the pass card CPC. Background technique [0002] Expressway construction is developing rapidly, and there are multiple paths from point A to point B. Since the construction investors of each path are different, it is necessary to identify which path the vehicle passes through when charging the highway toll, collect the corresponding fee, and pay the fee to the corresponding construction investor. Based on this CPC (Composite Pass Card) came into being. The CPC can not only replace the existing paper receipt or contactless chip card, but also has the function of DSRC (Dedicated Short-Range Communication). When the vehicle is driving on the expressway, the CPC can communicate with the identification antenna erected on the expressway and store the identification information in the Fixed files within CPC. At the high-...
