Highway facility polling device and method

Abstract

The invention provides a highway facility polling device and a highway facility polling method, which belong to the technical field of RFID (Radio Frequency Identification) and fingerprint identification. The highway facility polling device comprises a handheld polling device, an active RFID electronic tag and a passive RFID electronic tag, wherein the handheld polling device further comprises a double-frequency RFID reading-writing module; the module comprises a data interface, a power supply interface, an antenna, a duplexing filtering unit, a high-power amplifier, a low-noise amplifier, a radio frequency switch control unit, a radio frequency switch, a decoding unit, an encoding unit, a frequency selection unit, a frequency conversion unit and a frequency mixing unit. According to the highway facility polling device and the highway facility polling method provided by the invention, a 2.45GHz active RFID electronic tag and a 915MHz passive RFID electronic tag can be identified at the same time; a previous paper record is replaced and the data acquisition efficiency is improved; the working strength of polling workers is relieved; when a facility provided with the active RFID electronic tag is polled normally, information in the active RFID electronic tag can be obtained without stopping a car when the driving car enters a working range of the active RFID electronic tag.

Description

technical field [0001] The invention belongs to the technical field of RFID and fingerprint identification, and in particular relates to a highway facility inspection device and method using RFID technology and fingerprint identification technology. Background technique Expressway facility inspection is that the expressway management department sends inspection personnel to regularly inspect the expressway and its attached structures (route, roadbed, road surface, traffic signs, anti-collision guardrail, alarm, etc.) in order to ensure the normal operation of the expressway in the area under its jurisdiction. Telephone, along the electrical facilities, bridges and culverts and slope protection) to conduct inspections, provide data analysis to the maintenance management department of the expressway to improve management quality, so as to detect existing problems in time and take measures to prevent problems before they happen. Provide guarantee for the safe operation of exp...

AI Technical Summary

Problems solved by technology

In the case of insufficient inspection supervision and management personnel, it is impossible to determine whether the inspection personnel missed inspections, whether the inspections are in place, or even whether the inspection personnel find other non-professionals to perform inspections on their behalf, resulting in inspections that are superficial.

At the same time, due to the fully enclosed, cross-regional and high-speed characteristics of the expressway, compared with other traffic road inspections, the inspection route on the expressway is long, the inspection time is long, and it is easy to fatigue. The danger posed by inspectors is high

The existing road inspections use handheld terminals with RFID readers for electronic inspections. However, during the inspection process, it is necessary to stop and read information at a short distance. It is easy to cause traffic accidents due to temporary parking on the expressway. In addition, this type of terminal cannot determine whether the holder is an inspector, so there is a management loophole that can find someone to inspect on his behalf
