Embodiment Construction

[0021] Preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings, and the technical solution of the present invention will be explained more clearly and completely.

[0022] Such as figure 1 Shown is a fully automatic breathing device control system based on short-distance wireless transmission, including a host module (System Host) and a front module (Front module), where the host module includes a main MCU, a BLE host chip (BLE-Central / Broadcaster ), the fan drive unit (Motor Drv), the front module includes the BLE slave chip (BLE-Peripherial), and the pressure sensor (Relative pressure).

[0023] The BLE host chip and the BLE slave chip have pre-cured the paired ID key, and the BLE slave chip periodically sends broadcasts when it is not connected and waits for the BLE master chip to connect. The pressure data collected by the pressure sensor is transmitted to the main MCU at intervals, so that the main MCU adjusts...

Abstract

The invention discloses a full-automatic breathing device control system based on short-distance wireless transmission, which comprises a host module and a front module, and is characterized in that the host module comprises a main MCU, a BLE host chip and a fan driving unit, and the front module comprises a BLE slave chip and a pressure sensor; after the BLE slave chip is successfully connected with the BLE host chip, pressure data collected by the pressure sensor can be transmitted to the main MCU at an interval of about hundreds of milliseconds, so that the main MCU adjusts the rotating speed of the fan according to the current pressure value of the breathing bin body so as to change the pressure of the breathing bin body, and closed-loop control is realized. According to the invention, based on a separated modular design scheme, the advanced BLE wireless technology is utilized, the problem of short-distance data exchange between modules is solved, complex and tedious wired connection is avoided, and better convenience and effect are brought to structural design and user experience.

Description

technical field [0001] The invention relates to a fully automatic breathing device control system based on short-distance wireless transmission, belonging to the technical field of air filtering breathing equipment. Background technique [0002] In the field of mask-type air-filtering breathing devices, the products currently on the market are all designed through an integration, that is, the sensing element (sensor pressure and air volume data acquisition) and the actuator element (blower control, alarm indication) are connected to a single host through a cable , in order to achieve the purpose of closed-loop control. Since the position of the sensing element of the respiratory device usually needs to be as close as possible to the human mouth, the noise of the fan and the weight of the host will have a greater impact on the user experience. Contents of the invention [0003] Purpose of the invention: Aiming at the defects of the above-mentioned integrated wired connecti...
