Abstract

The invention discloses equipment for detecting physical characteristics of a highway RSU antenna. The detection equipment comprises a receiving antenna device, a frequency spectrograph, an encoder, a power supply and an upper computer. RSU signals are received through the signal receiving and analyzing device, physical characteristics of an RSU antenna are analyzed through the frequency spectrograph, and physical parameters are further analyzed, processed and displayed through upper computer software. The wireless signal field intensity distribution data in the lane is quantitatively analyzed according to the condition fed back by the detection equipment, and the abnormal state that the field signal intensity is too weak and the signal coverage is too small is found and assisted to solve.

Description

technical field [0001] The invention relates to a device for detecting the physical characteristics of an RSU antenna on a highway. Background technique [0002] Nowadays, the ETC system has become a necessary self-service system for many payment stations. However, the existing expressway ETC system sometimes has a state of communication loss between the on-board OBU, CPC and the roadside RSU system. Engineers can use spectrum analyzers to acquire signals and analyze data from problematic RSU equipment, and technicians are needed to analyze the data, which consumes manpower and material resources, and the problem-solving efficiency is not high. In order to quickly and quantitatively analyze the distribution of wireless signal field strength in the lane, discover and assist in solving the abnormal state of too weak signal strength and too small signal coverage on the spot, and without spending a lot of technical personnel, it is necessary to study a method that can be used o...
