Embodiment Construction

[0012] like figure 1 As shown, the active RFID device for detecting the PM2.5 content of automobile exhaust is designed with a mechanical card slot 102 in the casing 101, and the device can be installed outside the automobile chimney 103, and the laser probe of the PM2.5 laser dust sensor 202 needs to be ensured during installation. Part of it is facing the car exhaust chimney.

[0013] like figure 2 As shown, the active RFID device for the detection of PM2.5 content in automobile exhaust is implemented according to the following steps:

[0014] 1. The PM2.5 laser dust sensor 202 in the active RFID device for detecting the PM2.5 content of automobile exhaust is installed at the end 103 of the chimney of the automobile together with the device casing. In order to save electricity, the PM2.5 laser dust sensor 202 detects the PM2.5 content in the automobile exhaust in an adjustable and periodic manner. And convert the PM2.5 content into a voltage signal output.

Abstract

The invention provides an active RFID device for testing the PM2.5 content of automobile exhaust, and mainly solves the problems in the processes that a PM2.5 air quality sensor measures the PM2.5 content in the automobile exhaust and that data is sent to an RFID receiver integrated reception terminal capable of data collection in an active RFID manner. The device comprises the sensor capable of PM2.5 content detection, an MCU unit, an RFID chip, an RFID antenna, a casing and a battery. The PM2.5 content detection sensor is a laser dust sensor which can be controlled by the MCU to detect the PM2.5 content in the automobile exhaust, and the MCU stores obtained PM2.5 content data in a storage unit. An electronic circuit part, except a sensor probe, of the device is mounted in the mechanical casing, and the device is mounted in the tail end of an exhaust pipe of the automobile via a mechanical slot of the casing. When the automobile approaches the reception terminal with the RFID receiver, the MCU sends license information and the PM 2.5 content data in the exhaust of the automobile to the RFID reception terminal in the RFID manner.

Description

Technical field: [0001] This patent provides an active RFID device for detecting PM2.5 content in automobile exhaust, which involves PM2.5 particle content detection and RFID communication, and belongs to the technical field of electronic measurement. Background technique: [0002] With the increasing number of smog weather in our country, the content of PM2.5 in the air has become an important issue that people care about. Automobile exhaust is one of the important pollution sources of PM2.5. The domestic detection of automobile exhaust basically adopts the chassis power machine test method, which is mainly characterized by using a gas analyzer indoors to measure the content of pollutants in automobile exhaust, including CO, HC compounds, NOx, CO2, SO2, etc. . This method can only test the fixed vehicle, and cannot reflect the real situation of the car on the road in real time. For the above-mentioned pollutants, other known patents propose an automobile exhaust detectio...
