Intelligent double-frequency electronic label

Abstract

The invention discloses an intelligent dual-frequency electronic labeling, which includes a circuit wafer, a microwave circuit, an IC antenna, and an IC chip, where in, the microwave circuit has a power supply circuit, a charging system, a status indicator, a storage device, a SPI interface, a microprocessor in a MCU circuit, dual mode antennas, a filter circuit, an RF transceiver, a clock system; the invention has the advantages of that: 1. two frequencies are supported in work. 2. the invention can still work when a module is broken. 3. multi-path information is recorded. 4. programming is supported. 5. the invention is compatible with an existing system. 6. an IC card part is well protected, work state is stable.

Description

technical field [0001] The invention relates to an intelligent dual-frequency electronic tag. Background technique [0002] At present, the multi-path identification technology commonly used in the market is an important topic in the field of intelligent transportation ITS. It is an important means to realize the intelligentization of vehicle driving and road management, and it is also an important basis for expressway tolls. Multi-path recognition technology is of great significance in providing traffic efficiency, improving road traffic environment and saving traffic energy because it can realize the function of vehicle driving route marking and make vehicle driving and road management intelligent and informatized. [0003] At home and abroad, the development and research of multi-path recognition technology is still in its infancy, and there are no related products on the market. The main research direction of multi-path identification technology is to realize the commun...

AI Technical Summary

Problems solved by technology

[0007] 1. The accuracy of the source of system parameters cannot be guaranteed

[0008] 2. The update of system parameters lags behind, and the error is large

[0010] 4. Unable to provide a strong and convincing basis when there is an objection due to the split of the amount

[0011] 5. When an amount that cannot be split is generated, a large amount of funds will be stranded, affecting the normal operation and maintenance of the expressway

[0012] In addition, the ic card part of the existing structure is separated from the microwave circuit part, the ic card part is not well protected, and the working state is unstable

[0013] In short, in the current practical application of expressway toll collection, there is no marking device that can be put into practical use to record vehicle driving route information and is compatible with the requirements of existing toll collection characteristics.
