5G and NBIOT intelligent Internet of Things module

Abstract

The invention discloses a 5G and NBIOT intelligent Internet of Things module. The module comprises a main chip, a data module and a wireless network, the data module is connected with the main chip; the main chip communicates with a wireless network; the data module comprises a WIFI chip and an NFC near field communication chip. The WIFI chip is connected with an SIM / UCIM card slot through a USB interface. The NFC near field communication chip is connected with an SD card slot and an SIM / UCIM card slot through a UART interface, and an SIM / UCIM card used for user identity recognition and an SDcard used for data storage are inserted into the SD card slot; the NFC near field communication chip is connected with the main chip through an I2C interface, and the NFC near field communication chipis connected with the SD card reader through an SPI interface.

Description

technical field [0001] The invention belongs to routers, and in particular relates to a 5G and NBIOT intelligent Internet of Things module. Background technique [0002] At present, with the advent of 5G technology, the rise of narrowband communication represented by NBIOT has brought a new revolution to the automotive industry. Due to its large bandwidth and low latency, 5G can be used for unmanned driving of cars. At present, independent traffic monitoring and Wifi routing processing are used in automobiles. The built-in wireless module of the traffic management system and the independent GPS are expensive, slow, and difficult to develop. The on-board remote control system consists of an external array module connected to the main control MCU. , poorly optimized for low-power processing. [0003] There are mainly the following problems: 1. The delay of the current wireless network is relatively large, which cannot meet the response speed of the remote control of the car;...

Problems solved by technology

At present, independent traffic monitoring and Wifi routing processing are used in automobiles. The built-in wireless module of the traffic management system and the independent GPS are expensive, slow, and difficult to develop. The on-board remote control system consists of an external array module connected to the main control MCU. , poorly optimized for low-power processing

[0003] There are mainly the following problems: 1. The delay of the current wireless network is relatively large, which cannot meet the response speed of the remote control of the car; 2. The ECU (Electronic Control Unit, Electronic Control Unit) adopts the form of plug-in, which increases the difficulty of development and high cost; 3. When parking, the existing communication module consumes a lot of power, which will exhaust the car battery; 4. The security authentication is through the remote soft password method, which has poor security
