ETC front-mounted electronic tag and working method thereof

Abstract

The invention discloses an ETC front-mounted electronic tag and a working method thereof. The ETC front-mounted electronic tag comprises a Bluetooth module, a DSRC module, a CAN module and a signal receiving module connected with a vehicle-mounted inherent signal line and a communication interface. The Bluetooth module is used for receiving a control signal of the signal receiving module and / or the CAN module so as to switch the working state of the ETC front-mounted electronic tag. According to the invention, normal Bluetooth function and stable work of the ETC electronic tag can be ensured, and the use power consumption of the ETC electronic tag is reduced. A traditional Bluetooth key is replaced, so that the ETC equipment meets the requirements of the working temperature, the protection temperature, the protection grade and the like of vehicle regulations, and the ETC electronic tag is more reliable. A solar ETC electronic tag is replaced, and a vehicle-mounted power supply, a CAN bus signal or a vehicle-mounted signal are adopted to open Bluetooth, so that a solar cell module can be omitted, and the manufacturing cost of the ETC electronic tag is reduced.

Description

technical field [0001] The present invention relates to the technical field of ETC, and more specifically, relates to an ETC front-mounted electronic tag and a working method thereof, and specifically relates to a method and a system for switching working states of buttonless Bluetooth. Background technique [0002] With the continuous development of the Internet of Vehicles, the ETC electronic label has become a vehicle-mounted device, which can be considered as an ECU unit. [0003] With the widespread use of Bluetooth function activation, recharge, information query and other functions, Bluetooth has become a necessary function module for ETC equipment. On the one hand, in the Bluetooth module of the traditional rear-mounted vehicle-mounted ETC electronic tag, it is necessary to manually activate the Bluetooth function. After manually starting the Bluetooth function, the Bluetooth function is always on without turning off the Bluetooth, so it is always consuming power, w...

AI Technical Summary

Problems solved by technology

After manually starting the Bluetooth function, the Bluetooth function is always on without turning off the Bluetooth, so it is always consuming power, which is very expensive for ETC devices that use solar energy

[0004]When the ETC equipment is converted from an aftermarket product to a vehicle-mounted product, the ETC equipment needs to meet the requirements of the working temperature, protection temperature, and protection level of the vehicle regulations. The traditional Bluetooth Buttons have become a problem that pre-installed products have to solve; some ETC devices are installed in a hidden way, so that although there is no exposed Bluetooth button, the button is still retained in essence.
