Embodiment Construction

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0041] figure 2 It is a flow chart of Embodiment 1 of the power management method of the CPC card of the present invention. The power management method of this embodiment is applied in the power management module of the CPC card. Regarding the CPC card, it should be noted that it is mainly used for toll collection at highway entrances and exits. And other scenarios, in addition to the power management module, it also includes the main control module, 13.56MHz...

Abstract

The invention relates to a CPC card and a power supply management method thereof. The power supply management method comprises the following steps: judging whether to enter a non-contact scene according to an output signal of a 13.56 MHz coil; if a non-contact scene is entered, controlling the battery to stop supplying power to the main control module, and supplying power to the main control module by a coupling field induced by the 13.56 MHz coil, so as to enable the main control module to respond to an operation instruction of 13.56 M communication; identifying the type of the operation instruction, and controlling the battery to supply power to the main control module when the type of the operation instruction is a writing instruction, so as to enable the main control module to executethe writing instruction; and when the type of the operation instruction is not the writing instruction, entering a dormant state. By implementing the technical scheme of the invention, the power consumption is saved, and the service life of the CPC card is prolonged.

Description

technical field [0001] The invention relates to the ETC field, in particular to a CPC card and a power management method thereof. Background technique [0002] The composite pass card (CPC card) is an important terminal device in the field of quick toll collection without parking, and multiple technical specifications require that the CPC card has a life span of at least five years. [0003] In the conventional circuit design of the CPC card, such as figure 1 As shown, the main control chip (MCU) manages and controls the work of the entire system, and the battery directly supplies the MCU. Moreover, the 5.8GHz wake-up signal and the coupling field signal induced by the 13.56MHz coil wake up and enter the working state. Among them, the 5.8GHz wake-up signal is turned off in the exit state, and the coupling field signal induced by the 13.56MHz coil is the highest priority wake-up / processing signal of the entire system, and shielding / prohibition is not allowed. In order to in...
