1. Product knowledge and industry knowledge

1. What is digital key technology?


(1) BLE, that is, low-power super Bluetooth technology (5.1), is compatible with the original classic Bluetooth. The advantage is the popularity of Bluetooth on mobile phones, and Bluetooth control or automatic control can be achieved without carrying other carriers.


(2) PKE, this product adopts the world's most advanced RFID radio frequency technology and the most advanced vehicle identification code identification system, takes the lead in applying the development scheme of miniaturized, low-power radio frequency antenna, and successfully integrates the remote control system and keyless The system follows the traditional circuit protection of the whole vehicle, and truly realizes the dual radio frequency system and dual anti-theft protection, providing maximum convenience and safety for the owner.


(3) NFC, which is a., NFC is a wireless connection technology that provides easy, safe and fast communication, and its transmission range is smaller than RFID. The transmission range of RFID can reach several meters or even tens of meters, but due to the unique signal attenuation technology adopted by NFC, NFC has the advantages of short distance, high bandwidth and low energy consumption compared with RFID. The technology is compatible, and it has become an official standard supported by more and more major manufacturers. NFC is also a short-range connection protocol that provides easy, secure, fast and automatic communication between various devices. Compared with other connection methods in the wireless world, NFC is a close-range private communication method. , RFID is more used in production, logistics, tracking, asset management, while NFC plays a huge role in access control, public transportation, mobile payment and other fields.


 (4) (UWB) is the best positioning and tracking technology, because the original intention of ultra-wideband technology (UWB) is to achieve high-precision ranging estimation, and two-way communication at the same time. Therefore, UWB is the best and most advanced positioning technology today, which can be accurate to a distance of 0.1 meters.


products information 


(1) Voltage: low voltage 26-100V, suitable for 36V-48V-60V-72V, four voltage models. High voltage: 80-150V, suitable for 96V-108V-120V models.


(2) BLE technical characteristics and principles:


Advantages: popularization of mobile phones, convenience, strong sense of technology, large marketing concept of mobile phone locks, and affordable prices. It is a replacement technology. In the next few years, digital key technology will replace traditional anti-theft devices.

Disadvantages: The induction signal has errors, and the error distance is different in different scenes. The technical design of our product is 8-12 meters for locking, and 1-3 meters for unlocking.

Scenario application Note: Bluetooth technology is most affected by object obstruction, such as walls, glass, and iron doors, which will affect the sensing distance.


Special scene:


A. People carrying mobile phones have been staying within the range of 1-15 meters away from the car. This distance will be unlocked and locked from time to time. At this time, the user needs to use the applet to manually control, or the remote control.


B. No mobile phone signal: 1-2-3-4-5 floors underground, the mobile phone has no signal. In this scenario, our product does not affect the use, but it is based on a premise that it has been connected normally when the mobile phone has a signal, and the Bluetooth is kept open. For example: during the day


It is often used. The parking lot is on the minus 2 floor when I go home at night. After driving to the minus 2 floor, it will be locked as normal after parking and leaving. Go to work the next morning, go down to the F2 floor, approach the car, and the car is unlocked normally. (Assuming that the mobile phone on the negative 2nd floor has no communication signal)


C. Due to the different configurations of mobile phones brought by different people, there are stalls for customers to set the sensing distance themselves. The low-end mobile phone is powered down during driving, and it is only necessary to adjust the high-end, because the noise and vibration of the surrounding cars during driving


Elements will also affect the strength of the Bluetooth signal.


D. The signal strength will also be affected if the mobile phone is placed in trouser pockets, inner pockets of clothes, car trunks, handbags, etc. Therefore, when testing in an open place, it is adjusted to a low level, and many mobile phones have low configuration. In the process of using the digital key, it needs to be adjusted to a mid-range or even a high-end.

  

ERemember, do not have high expectations and 100% commitment to customers. We only need to objectively explain the technical limits, technical bottlenecks, and special application scenarios to customers according to the actual situation of digital key technology (now developed Bluetooth technology). . In the future we will not


The digital key of other technologies will be launched, and the complementary product line coverage will be done with the digital key of Bluetooth technology.


F. The product is equipped with three gears of automatic induction, namely: near, middle and far. When testing, adjust to the near file for testing. Due to the variety of mobile phone storage locations and the variability of the driving status of the car during driving, it is recommended to use the sensing distance when using it.


Away: Mid-range. Note: If there is an accidental power failure during driving, you need to immediately adjust to a higher induction gear.


2. Product installation process and attention points:


1. First look at how many wires are the anti-theft devices on the car? It is 5 or 6 wires, and our products can be installed. The 6 wires have more overspeed alarm function. If the overspeed alarm function is not needed, it can be cut off.


2. See how the jack on the car is connected to the anti-theft device? About half of the cars don't need a conversion cable, just plug it straight in.


3. About half of the cars in the entire market need conversion lines. The conversion cable has about eight interfaces for the conversion cable, all of which need to be prepared and ready to use at any time.


4. First of all, it is necessary to determine which interface to use. The line connecting the anti-theft device on the car is the female socket, then we need to find the corresponding male socket. If the anti-theft device interface on the car is male, we need to find the corresponding female socket.



5. Why don't we put the line of the socket of the conversion line? That is, considering that the functions of each brand of car are different, it is necessary to use a multimeter to test the online function of the car at this time. eg: video



6. If the original car has 8 wires/10 wires, our standard products are not suitable for installation. If it is the business of the pre-installation factory, we can provide samples and customize cooperation.
