The Bluetooth broadcast signal that standby intelligent hand-held terminal scanning surrounding Bluetooth slave devices issue, and select to need the bluetooth connected from setting
It is standby, request is actively initiated the connection to Bluetooth slave devices with bluetooth master identity, and establish connection, intelligent hand-held terminal and wearing
Pulse signal data communication is carried out by bluetooth master and Bluetooth slave devices between equipment.
Further, for the Bluetooth slave devices as GATT server end, bluetooth master is described as GATT client
Pulse signal data are supplied to GATT client by GATT server end, and the GATT client takes according to GATT
The Universally Unique Identifier UUID that business device end provides obtains the read write attribute value handle of " attribute value ", and reads " attribute "
It writes.
Further, the service that the GATT server end provides " attribute " be divided into " read-only ", " only writing ", " read-write ",
" notice " and " encryption is read-only " mode.
Further, the wearable device is wristband constructions, measures pulse signal for being worn in user's wrist.
Further, the intelligent hand-held terminal is mobile phone.
The beneficial effects of the present invention are:
Wearable device of the invention, which does not need to establish connection, can send the broadcast data of pulse signal, and intelligent handhold
Terminal listens to the data of wearable device sending as scanning device, and the intelligent hand-held terminal initiated the connection is by sending connection request
Wearable device is responded, if wearable device receives connection request, wearable device and the intelligent hand-held terminal that initiates the connection
Connection status will be entered, carry out carrying out pulse signal data communication, and the present invention is at low cost, delay is short, more power saving, continuation of the journey
Ability is good.
Detailed description of the invention
Fig. 1 is that the bluetooth communication of intelligent hand-held terminal and wearable device of the invention constructs schematic diagram；
Fig. 2 is that bluetooth master and Bluetooth slave devices of the invention carry out pulse signal data communication framework schematic diagram.
Specific embodiment
It is below with reference to the accompanying drawings and in conjunction with the embodiments, next that the present invention will be described in detail.
Shown in referring to Fig.1, a kind of pulse signal acquisition communication architecture based on Bluetooth transmission, which includes for acquiring
The wearable device of pulse signal and intelligent hand-held terminal for receiving pulse signal, wearable device are built-in with pulse transducer,
Human pulse beat signals are converted to voltage signal by the piezoelectric property of PVDF thin film by pulse transducer, processing is formed
Pulse signal data, the framework further include having bluetooth module, and the bluetooth module includes bluetooth master and Bluetooth slave devices,
The bluetooth master is set on intelligent hand-held terminal, and the Bluetooth slave devices are set on wearable device, the bluetooth from
Equipment is in broadcast state centered on wearable device, issues broadcast data packet under notconnect state, has the bluetooth master
The Bluetooth broadcast signal that the intelligent hand-held terminal scanning surrounding Bluetooth slave devices of equipment issue, and select to need the bluetooth that connects from
Equipment actively initiates the connection request to Bluetooth slave devices with bluetooth master identity, and establishes connection, intelligent hand-held terminal with wear
It wears and pulse signal data communication is carried out by bluetooth master and Bluetooth slave devices between equipment, and when not setting up connection, with
Sleep pattern is run with extremely low electric current, more saves electricity, improves cruising ability.
Referring to shown in Fig. 2, the Bluetooth slave devices are as GATT (i.e. General attribute profile) server
End, bluetooth master are supplied to as GATT client, the GATT server end using pulse signal data as " attribute "
GATT client, the GATT client obtain " attribute value " according to the Universally Unique Identifier UUID that GATT server end provides
Read write attribute value handle, and " attribute " is written and read.
