Wireless IC card for data read-write and storage of engine monitoring apparatus

Abstract

The invention discloses a wireless IC card used to read, write and store the data of in vehicle detector. It is characterized in that: said wireless IC card is a radio frequency IC card, which comprises an energy supplier, a signal write channel, a signal read channel and an information storage unit. Wherein, the energy supplier is formed by an inductance coil and a rectifier, which is used to receive the low-frequency alternative energy of card reader to be rectified into direct current energy, to support the storage card; the signal write channel uses three paths of modulated microwave signals to transmit the data, clock, and chip select signals to the IC card via couple channel, to be demodulated and stored into memory, while each patch comprise a microwave coupler and a detector; the signal reads channel is formed by a descending carrier channel and a read data channel, while the read channel is formed by a descending carrier coupler, a modulator multiplier, and a read data carrier coupler; the information storage unit is a serial flash memory.

Description

technical field [0001] The invention relates to a data read-write and storage device structure of a locomotive monitoring device, in particular to an IC card used in the locomotive monitoring device for setting driver parameters, inputting operation indication information and dumping operation record data. Background technique [0002] In the locomotive monitoring device, it is often necessary to record and dump some operating data. In the existing locomotive monitoring device, the recording and dumping of this operating data all use contact IC cards. Type IC card has some deficiencies, one is exactly that this contact type IC card runs through the contact metal part on the card, and the contact metal part on the card must be exposed in order to ensure contact. The exposed metal part is easy to wear because of repeated insertion / extraction. In addition, this exposed metal part is also prone to wear due to other reasons (such as external friction), so the existing contact IC ...

Problems solved by technology

But above-mentioned patent all can not be directly applied in the locomotive monitoring device

Chinese patent CN02283213.0, entitled "Non-contact IC card ground positioning shunting alarm control device", discloses a non-contact IC card device related to locomotives, but it is limited to ground positioning shunting alarm control, and still cannot be used for The locomotive monitoring device, and its specific IC card structure is not disclosed, so it is necessary to develop a wireless IC card system suitable for reading, writing and storing the data of the locomotive monitoring device, in order to improve its reading and writing of locomotive monitoring device data. storage adaptability
