The system block diagram of the intelligent wearable device provided by the invention is shown in fig. 1, and the intelligent wearable device comprises an MCU control unit, a radio frequency transceiving unit, a keyboard and display unit and a power management unit. In some specific embodiments, the MCU control unit comprises an MCU controller model MSP430F 449; the radio frequency transceiver unit comprises a wireless transceiver unit, specifically a wireless transceiver unit with the model of SX 1233; the keyboard comprises a custom 5-key keyboard; the display unit includes an LCD display unit. The above components are further described below:

1. MCU unit

The MCU controller with the model of MSP430F449 has the following advantages:

1) ultra-low power consumption: the power supply voltage is 1.8-3.6V, the standby current is less than 1 muA, the power consumption is only 0.1mA in the RAM data holding mode, the power consumption is 250 muA/MIPS (million instructions per second) in the active mode, and the maximum leakage current of an I/O input/output port is 50 nA. MSP430F449 has a unique clocking system design, including 2 different clocking systems: a basic clock system and a phase locked loop (FLL and FLL +) clock system or a DCO digital oscillator clock system. The clocks required by the CPU and the functional blocks are generated by a clock system and can be turned on or off under the control of instructions to achieve control of the overall power consumption. Because the functional modules used in the operation of the system are different, namely different working modes are adopted, the power consumption of the chips has obvious difference. There are 1 active mode and 5 low power modes in the system. In addition, vector interrupt is adopted, multiple interrupt sources are supported, and the interrupt sources can be arbitrarily nested. The CPU is awakened to the shortest time of 1 mu s by using an interrupt request, and through reasonable programming, the system power consumption can be realized, and the quick response to an external event request can be realized.

2) Powerful processing capacity: MSP430F449 is a 16-bit single-chip machine that employs the currently popular Reduced Instruction Set (RISC) architecture, which can execute 1 instruction 1 clock cycle. Meanwhile, a series of advanced architectures such as a 16-bit multifunctional hardware multiplier and the like are adopted.

3) High performance analog technology and rich on-chip peripheral modules: MSP430F449 combines the following functional modules: 12-bit ADCs, comparators, LCD drivers, supply voltage monitoring (SVS), serial communications (UART/SPI), hardware Multipliers (MPY), temperature sensors, watchdog timers (WDT), multiple 16-bit timers, etc.

4) The system works stably: after power-on reset, a CPU (digital control oscillator DCO is built in a single chip microcomputer) is started by DCO _ CLK firstly to ensure that a program is executed from a correct position and ensure that an external crystal oscillator has enough oscillation starting and stabilizing time. The final system clock frequency is then determined by software setting the control of the appropriate registers. If the crystal oscillator fails when used as the CPU clock MCLK, the DCO will automatically start to ensure the system is working properly.

The MCU is the core of the intelligent wearable terminal system, works in the LPM3 low power consumption state under the condition of no event, and can respond and exit the LPM3 state to enter the active working state when a key is pressed or wireless data is received.

2. Wireless transceiver unit

SX1233 is an ultra-low power consumption programmable ISM band transceiver from Semtech corporation, with the highest code rate worldwide (600kbps) and world-level link budget (137kB), ultra-low power consumption, excellent ACR (adjacent channel suppression) and anti-blocking capability. SX1233 provides high Receive (RX) sensitivity, enhances the reception capability for weak signals, and enables Transmitter (TX) output power to be programmed in 1dB steps. High RX sensitivity and TX output power equate to reliable transmission over longer distances, which saves cost compared to conventional radio frequency systems that require RF repeaters.

SX1233 has low power consumption in transmit, receive, and sleep modes, thereby extending battery life. Because there is constant RF performance in the 1.8 ~ 3.6V operating range, even without the stabiliser, also can guarantee stable communication when the battery life is about to terminate. In addition, by adopting the True RFTM technology, a SAW filter is not needed, the number of external components is reduced, and simultaneously the requirements of ETSI and FCC can be met. SX1233 also integrates a VCO tank, PLL loop filter, and an RF switch, further reducing the total material count.

The wrapper engine integrated in SX1233 may remove the RF wrapper work of the microcontroller, freeing up resources of the microcontroller, or allow the designer to choose an alternative that is less costly or less power consuming. The packet engine may also provide security for the transmission of data packets by CRC error checking, AES-128 encryption, and a 66 byte FIFO.

SX1233 has a frequency range of 290-1020 MHz and has been certified by global specifications including the European Union (ETSI EN300-220-1), North America (FCC part 15), and the ARIB regulatory standards of Korea and Japan. It also supports global modulation formats (FSK, GFSK, MSK, GMSK, OOK).

3. Keyboard and display unit

The keyboard comprises a custom 5-key keyboard, and particularly comprises an on-off button, a volume increasing button, a volume decreasing button, an answering button and a one-key calling button. 5 linking the ports P1.0-P1.4 of MCU, because the port P1 can accept the interrupt of external rising edge or falling edge, so it can adopt the interrupt key programming mode to save power consumption. The display unit is a customized segment type liquid crystal LCD, and an LCD driving module is arranged in the MSP430F449, so that the cost is saved and the volume is reduced. The maximum display segment number of the LCD driving module is 40 multiplied by 4 to 160 segments, the LCD driving module can directly store, read and write, control display, automatically generate liquid crystal driving signals, support 4 LCDs (static, 2mux, 3mux, 4mux) and support a flicker function.

A switch button: in the power-off state, long press starts. And in the starting state, the security power-off is carried out. And pressing for more than a few seconds for a long time, and forcibly restarting.

Volume increase: clicking the button increases the volume by one unit. The volume is continuously increased by long press until the maximum volume.

And (3) volume reduction: clicking the button decreases the volume by one unit. The volume is continuously decreased by long press until the volume is minimum.

Answering the button: when voice or video calls in, the button is clicked, and the call is connected. When the device is in a call state, the button is clicked, and the call is hung up.

One-touch call button: clicking the button, the device makes a voice call to a preset number. And long-time pressing the button, and calling the preset number by the video of the equipment. The preset number is obtained from the communication platform for the app installed on the device, only one number can be set, and the device end does not need to manage.

4. Power management unit

The intelligent wearable terminal adopts a 3.6V lithium battery for power supply, and the adopted MCU, the wireless transceiving module and the LCD are all 3.3V power supply devices, so that a battery power supply can be directly used. The MCU detects the power supply voltage regularly by adopting a basic timer for 1 minute, and actively alarms when the battery voltage is lower than 3.0V. The detection method comprises the steps of dividing half of the power supply voltage and sending the divided power supply voltage to a P6.3 port, adopting a 2.5V reference level generated inside the MCU, and utilizing an AD converter inside the MCU to realize A/D conversion so as to calculate the actual power supply voltage.
