Problems solved by technology

In this case, if the vehicle speed is 0km / h (that is, traffic jam) or is in a slow driving state, and the vehicle is just within the coverage of the sign station, the CPC card will always be woken up by the same sign antenna, which will greatly waste CPC card power

Abstract

The invention relates to a method and a CPC card for reducing power consumption of a CPC card in a traffic jam situation, wherein, the method comprises the following steps: receiving a current wake-upsignal sent from an antenna of an identification station, and judging whether an identification station corresponding to the current wake-up signal is the same as an identification station corresponding to a previous wake-up signal; If not, writing the identification station information corresponding to the wake-up signal into the CPC card; If the same, the current sleep time being determined according to the preset rule, and the CPC card being forced to sleep according to the current sleep time. The technical proposal provided by the application can reduce the power consumption of the CPC card in the traffic jam situation.

Description

technical field [0001] The application relates to the technical field of automatic control, in particular to a method for saving power consumption of a CPC card in a traffic jam situation and the CPC card. Background technique [0002] CPC compound pass card (Compound Pass Card) is an important part of the MTC (Manual Toll Collection system, highway semi-automatic lane toll system) system. In the expressway industry, the CPC card is applied to the multi-lane free flow technology. The carrier for recording and storing information such as entering and exiting toll stations, time and date, etc. is the pass volume for vehicles entering and exiting the high-speed road network. It is composed of a microprocessor, a storage unit, a radio frequency module, an antenna unit, a high-energy battery, and an IC card. The RFID and IC card readers conforming to the international mainstream 433M, 900M, 5.8GHZ and other ISM frequency bands perform real-time two-way communication to realize th...
