5.8G ETC license plate recognition module, effectively improving the accuracy of license plate recognition

The ETC recognition module is a module developed based on NWF580, which meets both the GB/T20851.1-2007 communication standard and the toll road network toll ambiguous path recognition two technical requirements.

The ETC recognition module uses 5.8G radio frequency technology, which can effectively quickly connect the ETC roadside unit (RSU) and the ETC on-board unit (OBU), and read the license plate number in the OBU and provide it to the parking lot gate. Control system use. The combination of 5.8G ETC module and camera vehicle license plate recognition technology can avoid bad weather conditions such as dim light, rain, fog, snow and other adverse weather conditions that affect the camera license plate recognition, and obtain OBU vehicle license plate information through radio frequency to improve equipment The purpose of the license plate recognition rate is to help system integrators effectively solve the problem of deduction caused by inaccurate recognition, realize more accurate deduction services, and improve user experience.
