Do you know how many RFID electronic tags exist in a car? With the popularization of RFID technology, the application of electronic tags is becoming more and more extensive. So what are the applications of RFID electronic tags in vehicle management? Come and learn about it with RFID tag manufacturer
YX IOT Technology!
As one of the key technologies of the Internet of Things, RFID also has many applications in the Internet of Vehicles. Today, let's take a look at how many electronic tags can a car have?
Wireless tire temperature and tire pressure monitoring
Using RFID technology, combined with temperature and pressure sensors, real-time monitoring of wireless tire temperature and pressure can be achieved. There are two main types of wireless tire temperature and tire pressure monitoring electronic tags:
Built-in wireless tire temperature and tire pressure monitoring electronic tag:
The sensor tag is built in the tire and is located near the valve door. The original one will be made together with the valve. The sensor tag is powered by the battery, and the measured tire temperature and tire pressure value are wirelessly transmitted to the receiver, and then displayed.
External wireless tire temperature and tire pressure monitoring electronic tag
The external monitoring principle is similar to the built-in one, the difference is that the sensor is not hidden in the tire, but is screwed on like a valve cover, just like the tire pressure gauge used when inflating, it also relies on the battery to power the sensor through wireless. The signal is transmitted and the receiver receives it and displays it.
In addition, it can also be divided into active tire temperature and tire pressure monitoring electronic tags and passive tire temperature and tire pressure monitoring electronic tags according to the presence or absence of batteries.
Car tire electronic label
Car tire electronic tags can solve the problems encountered in the current tire identification, traceability and other processes. At the same time, tire RFID electronic tags can write tire production data, sales data, usage data, retreading data, etc., and can be collected and read through the terminal at any time. The corresponding data, combined with the corresponding management software, can record and trace the tire life cycle data.
There are various forms of electronic tags for automobile tires, including implanted types (in the process of tire building, the electronic labels are implanted inside the tires, which can withstand deformation, high temperature, and high pressure during tire building and vulcanization), and there are also fitted types.
car smart key
The car keyless entry system, also known as the smart key system, is a control system composed of a transmitter, a remote control central lock control module, a driving authorization system control module, three receivers, and related wiring harnesses.
The car smart key adopts RFID (Radio Frequency Identification) technology. Usually, when the owner approaches the vehicle within a distance of about one meter, the door lock will be automatically opened and the anti-theft will be released; when leaving the vehicle, the door lock will be automatically locked and released. Enter anti-theft state. When the car owner enters the car, the in-vehicle detection system will immediately identify the smart card. At this time, the car can be started normally by simply pressing the start button (or knob), and the car key does not need to be taken out during the whole process.
Pressure Sensor Labels
The seat pressure sensor label is affixed under the seat cushion.
Compared with the traditional pressure detection solution: the intelligent passive pressure tag can not only detect whether there is someone on the seat, so that the system prompts the passenger to fasten the seat belt; it can also determine whether the seat is a child or an adult through weight detection. Information can be sent from the RFID reader to the car control unit, which in turn optimizes the airbag release angle for enhanced safety.
Humidity Sensor Label
The humidity sensor label is attached to the back of the chair.
Humidity tags use human detection elements to determine whether there is a person on the seat, eliminating the hassle of items triggering seat belt warnings, thereby improving system reliability.
In addition, humidity sensing electronic tags can also be applied to automotive liquid leakage detection. A typical configuration contains six to more than ten sensors, each location is assigned a unique EPC, which is placed in a specific EPC according to the size of the vehicle and the specific needs of the OEM. Leak detection is performed at the detection location or at the confluence point of the water flow, and the detection personnel only need to hold the reader and go around the car to query the sensor label.
temperature sensor label
Passive temperature sensor labels, affixed to suitable locations inside the car.
The innovative intelligent passive sensor can be used for wireless temperature monitoring in multiple areas, the unique RFID identification code supports automatic identification, the reader is connected to the in-vehicle gateway, and the automatic air conditioning system can read data in real time for automatic high-precision control.
The car owner can also manually set the air conditioning temperature and wind speed according to the temperature displayed by the central control system.
Windshield Electronic Tag
The windshield electronic label is attached to the windshield of the car.
Widely used in vehicle electronic environmental protection information card, high-speed non-stop electronic toll collection, self-service parking, vehicle free travel, vehicle congestion control guidance, vehicle speeding and other violation management, simple vehicle identification, vehicle annual inspection tracking management, auto finance mortgage asset management , used car management, etc.
The RFID anti-transfer and anti-removal windshield electronic tag solves the practical problem of electronic tags in the application process, that is, to ensure the "one object, one code" anti-transfer feature, and to achieve the minimum area of residual glue when the tag is removed or replaced, It is specifically suitable for various RFID applications that require anti-counterfeiting, anti-dismantling, and anti-residue glue residue, especially supply chain finance, asset management, etc.
car lamp electronic label
The electronic label of the car lamp can be attached to the headlight of the car, and its function is similar to that of the windshield label.
Liquid level detection electronic label
Vehicle liquid level detection includes the detection of fuel tank fuel level, oil level, brake fluid level and acid liquid level. Traditional automotive fluid level detection systems require wires to be connected and must be located inside the container.
Smart passive sensors sense the liquid level outside the vessel, eliminating sensitive electronics in the tank. The sensor labels are optimized for the dielectric constant of liquids and can detect a wide variety of liquids; they can be up to 4 inches in length to accommodate the need for multiple sensor labels on the outside of space-constrained containers.
The development of the Internet of Things has driven all walks of life, and the Internet of Vehicles is also a new network technology based on this. With the continuous improvement of RFID and sensing technology, the application of electronic tags in automobiles is bound to become more and more extensive.
