Embodiment Construction

[0041] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with aspects of the invention as recited in the appended claims.

[0042] At first the terms involved in the present invention are explained:

[0043] Electronic Toll Collection (ETC for short): Through the microwave-specific short-range communication between the OBU installed on the vehicle windshield and the RSU on the ETC lane of the toll station, it uses computer networking technology to perform background settlement with the bank Processing, so as to achi...

Abstract

The invention provides a method and apparatus for reducing OBU power consumption. The method comprises steps: a card reader chip is controlled to read user card information; the reading function of the card reader chip is controlled to be closed; and a display is controlled to display fee information generated according to the user card information. In the method, before the display displays the fee information, the MCU closes the reading function of the card reader chip, and thus, during the whole process of displaying the fee information by the display, the card reading function of the cardreader chip is in a closed state, the power consumption of the card reader chip is reduced, and the whole OBU power consumption is thus reduced.

Description

technical field [0001] The invention relates to communication technology, in particular to a method and device for reducing power consumption of an OBU. Background technique [0002] The electronic toll collection system (Electronic Toll Collection, referred to as ETC) is currently a more advanced way of toll collection for roads and bridges; Microwave dedicated short-range communication between Road Side Units (RSU for short), as well as computer networking technology and bank background settlement processing, to achieve the purpose of paying road and bridge tolls without stopping when vehicles pass through road and bridge toll stations. At present, the OBU is powered by a lithium battery plus a solar battery, and the service life of the battery is limited. In order to increase the number of transactions completed by the OBU during the limited service life, it is especially important to reduce the power consumption of the OBU. [0003] In the prior art, after completing th...
