Abstract

The invention provides a sensor network, a method and a storage medium, and the sensor network comprises more than one sensor module which are connected with the same data / control bus and is used forreading and writing data to the data / control bus; a DMA controller which is connected with the data / control bus, and the DMA controller is used for reading and writing data to the data / control bus; astorage module which is connected with the DMA controller, and the storage module is used for storing data transmitted by the sensor module through a data / control bus; and more than one processing module which are connected with the storage module, and the processing module reads and writes data from the storage module. The sensor network provided by the invention can optimize the data processingmode of the sensor network system for the intelligent equipment with periodicity in load operation under the condition of limited computing resources, so that the overall power consumption and cost ofthe intelligent equipment are reduced.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of smart devices, and in particular, to a sensor network, a method, and a storage medium. Background technique [0002] The current smart devices or smart systems have more and more sensors, and a large amount of sensor data needs to be processed and stored. Most of the current smart devices, such as mobile phones, use SensorHub as the main control module, using the specially opened memory space in RAM to process sensor data, and further storage and processing of data need to be uploaded to the central processing unit (CPU) for processing , not only need to occupy memory and CPU resources, but also have relatively high performance requirements for memory and CPU. [0003] For smart devices in the fields of smart home and environmental monitoring, due to performance requirements such as low power consumption and long battery life, the diversity of product forms caused by adapting to hom...
