The prevalence of shared bicycles has provided us with more opportunities to contact smart locks. As users, we only need to understand the unlocking channels to "scan — unlock — ride — after riding, manually lock "; As a professional supplier of positioning modules, wireless modules and solutions, SKYLAB has also developed modules and solutions suitable for shared bicycles. Let’s look down.
Those who have a certain understanding of smart locks know that the wireless module is the core hardware of the shared bicycle smart lock, including: GPS positioning module, global communication module, central control unit, Bluetooth module, electromechanical lock device, etc. Among them, SKYLAB has the best knowledge of GPS positioning module and Bluetooth module. Not long ago, it also launched two smart lock solutions suitable for shared bicycles. They are based on SKC111 and BLE based on Bluetooth module SKB369. Those who are interested can find SKYLAB. Take a look at the smart lock solution article published by Jun ("Scheme Show" SKYLAB Smart Lock Solution).
Regarding the GPS positioning module, in order to facilitate the user to find a car, Mobike has a GPS positioning module embedded in the smart lock, and the user can obtain the location of all nearby shared bicycles by opening the APP. However, the advantage of "riding and releasing" shared bicycles will also become a point of reducing user satisfaction when looking for a car. GPS is under weak signal environments such as shade trees, high-rise buildings, viaducts, tunnels, and underground parking lots. Unable to provide accurate positioning information, the map shows that the car is nearby, and there are no cars around. In response to this phenomenon, Mobike also released a new generation of smart locks at the same time as the new car, which further improved the unlocking success rate. From the perspective of the built-in positioning module, the new generation of smart locks also supports "Beidou + GPS" multi-mode satellite positioning. It can be positioned with high accuracy in places where ordinary GPS receiver modules cannot be positioned, such as under the narrow urban sky and dense jungle environments.
About multi-mode satellite positioning module
In view of the characteristics of renting and returning shared bicycles anytime, anywhere, to improve the use experience, its positioning accuracy must be high and its performance must be stable to avoid positioning in an environment such as rainy days and lush trees. SKYLAB's Beidou positioning module (multi-mode) is a miniaturized module integrating Beidou & GPS positioning functions. The module has high integration, low power consumption, and is compatible with receiving GPS/BDS/GLONASS/GALILEO satellite navigation signals. It can realize real-time positioning and timing of the carrier. , Speed ​​measurement and other functions are very suitable for the needs of large-scale system applications; it can maintain the lowest system power consumption while having the maximum sensitivity, the internal Flash can be upgraded to support different applications; it has an additional front LNA to optimize RF performance , Easy to integrate with the antenna, and the front SAW filter strengthens the anti-jamming performance; the Beidou positioning module (multi-mode) can be a single Beidou module, a single GLONASS module, a GPS+Beidou module, and a GPS+GLONASS module according to different programming procedures. . At present, SKYLAB Beidou + GPS dual-mode positioning module has the following mature models: SKG09D, SKG12D, SKG17D.
The Beidou multi-mode positioning module has many advantages such as high sensitivity, low power consumption, and miniaturization. At present, Beidou has been widely used in positioning system LSB (LocaTIon Based Service), portable self-navigation system PND (Portable NavigaTIon Device), mobile phone (mobile phone ), Vehicle navigaTIon system, vehicle monitoring, driving recorder, surveying and mapping, handheld devices and other products, as the extremely important positioning module in positioning navigation, it is more important to choose the Beidou module that meets the positioning needs of product applications.
The advantage of entertainment tablet lies in having a powerful chip and excellent hardware. If you want to play various online videos on the tablet and run various software smoothly, the performance of the hardware is an absolute prerequisite. In addition, a high-speed and stable WIFI module is also required, which must be compatible with multiple 802.11 B/G/N protocols at the same time, so that the webpage can be loaded instantly when the webpage is opened, and the online video can be played smoothly. So hardware is the premise and foundation, without good performance everything else is empty talk.
In addition to having a good CPU as a prerequisite, it is equally important to carry a professional video player. A professional video player must perform equally well both online and offline.
