Description

A perception structure based on low energy bluetooth BLE

technical field

The invention belongs to the technical field of bluetooth low power consumption (BLE), and in particular relates to a BLE sensing structure and method based on low power consumption bluetooth.

Background technique

Bluetooth Low Energy (BLE) technology is a low-cost, short-range, interoperable and robust wireless technology that operates in the license-free 2.4GHz ISM radio frequency band. It was designed from the ground up as an Ultra Low Power (ULP) wireless technology. It utilizes many smart measures to minimize power consumption. Bluetooth low energy technology uses a variable connection time interval, which can be set from a few milliseconds to a few seconds depending on the specific application. In addition, because BLE technology uses a very fast connection method, it can be in a "non-connected" state (to save energy) at ordinary times. The link may be shut down for a short period of time.

The mode of operation of BLE technology is ideal for transmitting data from tiny wireless sensors (which exchange data every half second) or other peripherals such as remote controls using fully asynchronous communication. These devices send very small amounts of data (usually a few bytes) and very infrequently (eg, a few times per second to once per minute, or even less).

The existing perception technology is mainly realized through some other technical means. 1. NFC near-field communication. NFC near-field communication technology is evolved from the integration of non-contact radio frequency identification (RFID) and interconnection technology. It combines inductive card readers, inductive cards and point-to-point functions on a single chip. It can identify and exchange data with compatible devices within a short distance. The disadvantage is that the distance of this method is very limited (≤0.1m), which leads to very limited application occasions. 2. Allow the user to actively scan the QR code to obtain surrounding information, and guide the user to obtain the information corresponding to the QR code by scanning the QR code. The disadvantage is that users are required to actively scan the QR code, and the perception effect and experience are poor.
