Smart bike lock is a kind of hardware for dockless bike sharing business.IoT technology is arranged in the device,and it cooperates with bike sharing APP and server background to form a perfect bike security system with mobile.
First,what are the core technologies of smart bike lock?
1.Bluetooth chip
In fact,there's a built-in Bluetooth chip for every smart unlocked bicycle.The characteristics of this chip is ultra-low power consumption,and in terms of security,the introduction of Bluetooth"LE Secure Connections"secure pairing method makes the combination of Bluetooth and lock more smooth and reasonable.
The main function of the Bluetooth chip is to support positioning.It can directly drive the motor,and support multiple unlocking methods,such as QR code scanning method,MAC address recognition,bicycle number input,Bluetooth connection method unlocking,etc..In addition,this Bluetooth chip also supports receiving GSM,GPRS network,W-CDMA network and TD-SCDMA network data.
So when you use a sharing bike,the bluetooth of your mobile phone is connected to the built-in bluetooth chip of the bicycle,and the built-in bluetooth chip is given a signal by scanning the code with the mobile phone.By this signal,you can drive the direct drive motor to unlock,obtain the bicycle location information,and transmit the information to the cloud platform.
2.Remote bike lock is a 2G network standard with SIM module.
A SIM card with an independent number is integrated in the smart bike lock,which maintains communication capabilities with the cloud through 3G and 4G networks,and reports the vehicle's location (GPS information) and the current status of the vehicle to the cloud in a timely manner.
Secondly,application function of smart bike locks
Today's new functions such as Bluetooth unlocking,electric fence,and appointment,the key and basic functions of smart bike lock have been gradually determined,and the differences between different bike locks with alarm and gps are not big.At present,all the smart locks are basically composed of several major modules such as control,communication,perception,execution,and power supply.
The main module functions are as follows.
Control chip(single-chip microcomputer)
As the control center of the smart lock system,it is responsible for communication,lock control and status information collection as a whole.
Mobile communication chip(Modem)
Built-in Sim card of telecom operator,responsible for communication with cloud application background.
Bluetooth communication module
It is mainly used to connect to the user's mobile phone and realize unlocking,and it is also related to the application realization of the electronic fence.
GPS communication module
physical positioning function
The sensor of the bike gps lock
It is to sense the opening and closing status of the smart bike lock,and to report the status information of the bike gps lock to the control chip.
The actuator of the bike gps lock
To monitor the opening and closing operation of the smart bike lock through the actuator.
Buzzer
Used for audible alarm in abnormal state
Power module
Battery,charging module(chip),charging device(solar panel,motor and speed sensor,etc.)
The Bike security alarm system is actually completed through the information transmission between"bike-cloud-user mobile phone",the most critical of which is the process of unlocking the smart lock.At present,the latest"GPS positioning+Bluetooth"unlocking and car return mode has become more common.
