What kind of smart lock chip does the OFO share the bicycle lock? This article tells you the answer

What kind of smart lock chip does the OFO share the bicycle lock? What is the power consumption of Huawei NB-IoT module? The technical advantages of NB-IoT chip are explained in detail. The small yellow car, which is the OFO shared bicycle, is a new generation of travel tools that can be seen everywhere. It is always on the same track as the Mobike bicycle. The OFO bicycle smart lock has always used the ordinary password lock, which is easy to be cracked. Based on market demand. Recently, ofo/China Telecom/Huawei cooperated to launch a new shared bicycle lock chip solution.

This kind of chip is Huawei's new generation of Internet of Things solution - NB-IoT chip, and is also an important tool for Huawei to deploy the Internet of Things, because it will be used in the OFO shared bicycle smart lock and has attracted much attention.

OFO has announced a cooperation agreement with Huawei and China Telecom, and the three parties jointly developed NB-IoT technology to provide intelligent solutions for sharing bicycles. According to the agreement, China Telecom provides wireless network resources for OFO, and Huawei provides NB-IoT chips.

So what are the characteristics of NB-IoT, a small chip? As a result, OFO confidently laid out the next generation shared bicycle smart lock solution.

NB-IoT is a new generation of chips developed by the Narrow Band Internet of Things (NB-IoT). The NB-IoT technology features are as follows:

1, based on cellular narrow-band IoT technology, occupying less bandwidth resources, can support the deployment of multiple network standards, such as GSM, UMTS/LTE, and so on.

2, low power consumption, NB-loT technology supports long-term efficient connection, is an ultra-low power chip, can effectively extend battery life.

3, wide coverage, can achieve full network coverage, stable connection.

4, excellent architecture optimization, NB-IoT architecture optimization is very good, in a variety of network standard environment, good performance, stable performance, various indicators also meet the requirements.

5, low cost, NB-IoT chip is based on the existing technology research and development, with successful cases, can coexist with the existing network.

The NB-IoT chip is based on a cellular network, has low power consumption and extremely low traffic requirements, and is an ideal new technology for the Internet of Things.

The NB-IoT chip consumes about 180KHz of bandwidth and supports low-power devices in the WAN cellular data connection, so it is also a low-power wide area network (LPWA).

NB-IoT technology equipment has long standby time, supports long-term efficient connection, and can communicate in real time. According to tests, the battery life of NB-IoT equipment can be effectively improved. Some products can be improved for more than 10 years, and support full coverage of cellular data. Therefore, it is an ideal choice for sharing bicycle smart lock chips.

Based on the above characteristics and advantages, NB-IoT chip can be said to be the most ideal shared bicycle smart lock solution at present. Ultra-low power consumption and realization of Internet of Things are inevitably the mainstream development trend of shared bicycles.

NB-IoT technology will effectively solve the shortcomings and common problems of the current shared bicycles. It can break through the dilemma such as low 2g network connection speed, poor coverage, low connection capacity, and high total stability. It solves the problem of low success rate of unlocking, poor stability and environmental adaptability. Short board with weak ability.

Semiconductor Fuse And Ferrite

Fuse refers to an electric appliance that, when the current exceeds the specified value, melts the fuse and disconnects the circuit with the heat generated by itself.When the current exceeds the specified value for a period of time, the fuse melts and disconnects the circuit with the heat generated by the fuse itself.A current protector made from this principle.The fuse is widely used in high and low voltage power distribution system and control system as well as power equipment.

Ferrite is a metal oxide with ferrous magnetism.As far as electrical properties are concerned, the resistivity of ferrite is much larger than that of single metal or alloy magnetic materials, and it has higher dielectric properties.Ferrite magnetic energy also shows high permeability at high frequencies.As a result, ferrite has become a non-metallic magnetic material widely used in the field of high frequency and weak current.Due to the low ferrite magnetic energy stored in the unit volume, saturated magnetic induction strength (Bs) and low (usually only pure iron 1/3 ~ 1/5), and thus limits its higher requirements in the low-frequency magnetic energy density in the field of high voltage and high power applications.
