What is the shared car unlocking principle? How to share the car Bluetooth lock to unlock the phone? Sharing cars is a new mode of travel, which has attracted much attention due to its convenient use and relatively reasonable fees. It has become another viable travel solution after sharing bicycles. We all know that after sharing a car to make an appointment through a mobile phone and implementing smart unlocking in a mobile phone app, what is the technical principle of this quick operation process?
The door lock of a shared car is in fact a Bluetooth lock. The principle of opening a door is similar to that of a shared bicycle Bluetooth unlock, which is unlocked through a mobile phone APP.
The main principle is that the mobile phone and the car lock chip realize communication through Bluetooth technology, and the mobile phone realizes communication through the APP and the server, and the data transmission between the two parties.
The core principle lies in the Bluetooth short-distance communication function. Bluetooth can transmit data commands when it is connected. This is the basis for the shared car to unlock the mobile phone. The specific steps are as follows:
1, mobile phone APP to find a nearby available car, view the car information, select and reserve the car, the user clicks smart unlock, this time the database number information of the vehicle will be sent to the server through the phone, and request the unlock operation (need network connection support) .
2. The server receives the user's request, confirms the vehicle's information, and locates and sends the unlock command (Bluetooth unlocking key).
3. The mobile phone APP receives the unlock command and transmits it to the car lock chip through the Bluetooth connection. Note that the mobile phone needs to stay open in the Bluetooth connection range.
4, The vehicle lock chip receives the unlock command, executes the unlock operation, commands the lock cylinder to open the lock action, and the door lock is automatically opened.
5. The unlocked state of the central locking of the door allows the user to enter the cab and close the door for use.
6. Close the door when returning the car. The lock will be automatically closed. At the same time, click to end the use in the mobile phone APP to end the journey.
The above is the smart lock Chinese network Xiaobian finishing publishing shared car unlocking principle, more car lock knowledge, please pay attention to the content of this site!
INCONEL®
Yuhong Group supplies Inconel® alloys C-276, HX, 22, 600, 601, 625 & 718 in the form of Plate, Sheet, Bar, Wire, Pipe, Tubing, Pipe Fittings, Flanges and Electrode.
The registered trademark name, Inconel, is applied as the prefix name to more than twenty different highly corrosion resistant high temperature strength metal alloys produced by Special Metals Corporation. These Inconel alloys or superalloys are nickel-based alloys that exhibit traits such as high resistance to corrosion, oxidation, carburization, pitting, crevice, corrosion cracking, and high temperature strength. Often, Inconel is referred to as [Inco".
Alloys of identical chemical and mechanical properties are available from other manufacturers and offer excellent alternativesto the various Inconel® brand alloys.
The corrosion-resistant superalloys are widely used in extreme environments where tremendous heat and corrosion resistance is paramount to the integrity of the end product. Chemical processing, nuclear, petrochemical, aerospace and marine industries widely use these superalloys.
What are the Characteristics of Inconel ?
Good resistance to acids, such as sulfuric, phosphoric, nitric, and hydrochloric
Almost completely free from chloride induced stress corrosion cracking
Excellent mechanical properties at both extremely low and extremely high temperatures
Outstanding resistance to pitting, crevice corrosion and intercrystalline corrosion
High resistance to oxidation at elevated temperatures
In what Applications are Inconel alloys used ?
Chemical and petrochemical processing
Components where exposure to high mechanical stress and sea water are required
Flare stacks on offshore oil platforms
Gas turbines, rocket motors/engines, and space craft
Pollution control equipment
Nuclear reactors
