Abstract

The invention discloses a high-safety application module of the Internet of Things. The high-safety application module is composed of a communication module supporting one or more protocols of GPRS, 2G, 3G, 4G, 5G and NB-IOT, an Internet of Things card chip and a safety main control chip. The safe main control chip is a management chip which is low in power consumption and high in reliability andis provided with a data interface and a sensor interface, is externally connected with various sensor chips and modules which comprise one or more of an acceleration sensor, a temperature and humiditysensor, a sound sensor, an image sensor, an infrared sensor, an NFC controller, a Bluetooth module, a ZIGBEE module and a WIFI module, preprocesses and caches the acquired data, awakens the communication module to perform network connection according to a data processing or set timing working mode, and completes intermittent receiving and transmitting of data and commands, and is provided with more than two anti-crash protection mechanisms including a watchdog counter and a timing restart mechanism.

Description

technical field [0001] The invention relates to an IoT high-security application module including a communication module, an IoT card and a security main control chip, which can independently complete application functions, connect external sensors and control circuits, and can also be safely upgraded through a background service system. [0002] technical background [0003] Ordinary IoT modules only include connection functions, without application processing functions, and require a team with hardware and software design capabilities to use them. If the complete application support environment is put into the IoT module, any software team can easily carry out secondary development and application expansion, expanding the flexibility and scope of use of the IoT module. Contents of the invention [0004] The invention discloses a high-security application module for the Internet of Things, which is characterized in that it is composed of a communication module, an Internet...
