You know how many RFID tags exist in a car? With the popularity of RFID technology, the application of electronic tags more and more extensive, RFID tags used in the automotive industry is not an uncommon thing, its role is also played to the fullest. So in the vehicle management, RFID tags have what applications? Come with the smart card and RFID tag manufacturer tractility to understand it!
Wireless tire temperature and pressure monitoring
Table of Contents
The use of RFID technology, combined with temperature and pressure sensors, you can realize the wireless tire temperature and pressure monitoring in real time. Wireless tire temperature and pressure monitoring electronic tags are mainly two kinds.
1. Built-in wireless tire temperature and pressure monitoring electronic tags
The sensor tag is built in the tire is located near the valve, the original factory will do with the valve together, the sensor tag relies on battery power, the measured tire temperature, tire pressure value through the wireless transmission to the receiver, and then display out.
2. External wireless tire temperature and pressure monitoring electronic tag
External monitoring principle is similar to the built-in, the difference is that the sensor is not hidden inside the tire, but screwed on like a valve cover, like the tire pressure gauge used when inflating, it also relies on the battery to power the sensor through wireless transmission of signals, the receiver receives and then displays.
In addition, also can be divided into active tire temperature and tire pressure monitoring electronic tag, passive tire temperature and tire pressure monitoring electronic tag according to the presence or absence of battery.
Automobile tire electronic label
Automobile tire electronic tag can solve the current tire identification, traceability and other process problems encountered, at the same time, tire RFID electronic tag, can write tire production data, sales data, use data, retreading data, etc., and can read the corresponding data through the terminal collection at any time, and then combined with the corresponding management software, you can realize the tire whole life cycle data records and traceability.
The automobile tire electronic label has various forms, there are implantable (in the tire molding process, electronic label implanted into the tire interior, can withstand the tire molding and vulcanization process deformation, high temperature, high pressure), there are also laminated type.
Auto Smart Key
Automobile keyless entry system, also called intelligent key system, is a control system composed of transmitter, remote central lock control module, driving authorization system control module three receivers and related wiring harness.
The car smart key adopts RFID (Radio Frequency Identification) technology. Normally, when the owner approaches the vehicle within a distance of about one meter, the door lock will automatically open and lift the anti-theft; when leaving the vehicle, the door lock will automatically lock and enter the anti-theft state. When the owner enters the vehicle, the vehicle detection system will immediately identify the smart card, then just gently press the start button (or knob), you can start the vehicle normally, the whole process, the car key does not need to take out.
Pressure sensor label
The seat pressure sensor label is attached under the seat cushion.
Compared with traditional pressure detection solutions: intelligent passive pressure tag, not only can detect whether there are people on the seat, so that the system prompts passengers to fasten the seat belt; also through weight detection to determine whether the seat is sitting on the child or adult, this information can be sent from the RFID reader to the car control unit, and then optimize the airbag release angle to enhance safety.
Humidity sensor tag
The humidity sensor label is attached to the seat back.
Humidity tag through the human body detection elements can determine whether the seat is occupied, eliminating the trouble of items to trigger the seat belt warning, thereby improving system reliability.
In addition humidity sensing electronic tags, can also be applied to automotive leak detection, a typical configuration contains more than six to ten sensors, each location assigned a unique EPC, according to the size of the vehicle and the specific needs of the OEM, placed in a specific detection location or water flow confluence for leak detection, the inspector only need to hold a reader around the vehicle to query the sensor tag can be.
Temperature sensor tag
Passive temperature sensor tags that are placed in the right place inside the vehicle.
The innovative smart passive sensor can be used for wireless temperature monitoring in multiple areas. The unique RFID identification code supports automatic identification, and the reader is connected to the gateway inside the car, so the automatic air conditioning system can read the data in real time for automatic high-precision control.
The owner can also manually set the air conditioning temperature and air speed according to the temperature displayed by the central control system.
Windshield electronic tag
Windshield electronic tag, attached to the windshield of the car.
Widely used in vehicles electronic environmental protection information card, high-speed non-stop electronic toll collection, self-help parking lot, vehicles free flow, vehicles governing blockage guidance, vehicles speeding and other violation management, vehicles simple identity recognition, vehicles annual inspection chase management, automobile finance mortgage assets management, used vehicles management, etc.
Windshield electronic tags are divided into ordinary tags and anti-tampering tags, RFID anti-transfer anti-tampering windshield electronic tags, to solve the practical problems in the application of electronic tags, that is, to ensure that “one thing one code” anti-transfer characteristics, and in the tag removal or replacement to achieve the smallest area of residual glue, specifically for a variety of needs anti-counterfeiting, anti-tampering It is specifically applicable to various RFID applications that require anti-counterfeiting, anti-demolition and anti-gum residue, especially supply chain finance, asset management, etc.
Electronic tags for headlights can be attached to the headlights of automobiles, with similar functions as windshield tags.
Liquid level inspection electronic tag
The automobile liquid level inspection includes the inspection of fuel tank oil level, engine oil level, brake fluid level and acid liquid level, etc. Conventional automotive liquid level detection system needs to be connected to wires and must be located inside the container.
Smart passive sensors can sense the level outside the container, eliminating the need for sensitive electronics in the tank. Sensor tags are optimized for the dielectric constant of liquids and can detect a wide range of liquids; their length is up to 4 inches, thus meeting the need for multiple sensor tags outside the container where space is limited.
The development of the Internet of Things has driven all walks of life, and the Internet of Vehicles is a new network technology based on this. With RFID, sensing technology continues to improve, the electronic label in the automobile application is bound to be more and more extensive.
