[0029] The circuit logic problem of the dual-system coordinated work is solved by the power supply system 3 and the circuit of the coordinated control signal module 4. Figure 3 and Figure 4 As shown, the specific power supply system 3 includes a communication power supply end, which includes a power control switch U1, a resistor R1, a resistor R2, a resistor R3, a diode D1, a capacitor C1, and a transistor Q1.

The power supply system 3 controls the output of the POWER_ON_4G pin and the POWER_DOWN_4G pin in the communication power supply terminal to control the public network communication system 2 to enter the startup, sleep or shutdown state.
[0030] like Figure 5As shown, the power supply system 3 includes an MCU power supply end, and the MCU power supply end includes a power control switch U2, a resistor R4, and a capacitor C2. The A1 pin of the power control switch U2 is connected to the power VBAT end, the A2 pin of the power control switch U2 is connected to the VBAT_MCU end of the low-power MCU system 1, the B2 pin of the power control switch U2 is grounded, the B1 pin of the power control switch U2 is connected to the POWR_ON_MCU pin of the low-power MCU system 1, the C2 pin of the power control switch U2 is connected to the POWR_DOWN_MCU pin of the low-power MCU system 1, the C1 pin of the power control switch U2 is respectively connected to the resistor R4 and the capacitor C2, the other end of the resistor R4 is connected to the USB_VBUS end, and the other end of the capacitor C2 is grounded. The power supply system 3 controls the low-power MCU system 1 to enter the startup, sleep or shutdown state by controlling the output of the POWER_ON_MCU pin and the POWER_DOWN_MCU pin in the MCU power supply end.
[0031] like Figure 7 As shown, the power supply system 3 also includes an MCU switch circuit, which includes a resistor R7, a resistor R8, and a diode D2. The POWER_KEY pin of the MCU switch circuit is connected to the negative electrodes of the resistor R7, the resistor R8, and the diode D2 respectively, and the other end of the resistor R7 is connected to the power supply VBAT terminal, and the other end of the resistor R8 is connected to the POWER_ON_MCU pin of the low-power MCU system 1. The positive electrode of the diode D2 is connected to the POWER_KEY_TO_MCU pin of the low-power MCU system 1. The power supply and power-off of the low-power MCU system 1 are controlled by controlling the opening and closing of the MCU switch circuit.
[0032] like Figure 6 As shown, the power supply system 3 also includes a transistor Q2, a resistor R5, and a resistor R6. The RST_BY_MCU pin of the low-power MCU system 1 is connected to the resistor R5, and the other end of the resistor R5 is respectively connected to the base of the transistor Q2 and the resistor R6. The emitter of the transistor Q2 is connected to the other end of the resistor R6 and grounded, and the collector of the transistor Q2 is connected to the POWR_ON_4G pin of the public network communication system 2. This circuit is respectively connected to the power reset end of the low-power MCU system 1 and the public network communication system 2. When the public network communication system 2 works abnormally, the low-power MCU system 1 can reset the public network communication system 2.
[0033] The specific circuit of the coordination control signal module 4 is as follows Figure 8As shown, it includes resistors R9, R10, R11, and R12. The UART_TX_MCU pin of the low-power MCU system 1 is connected in series with the UART_RXD_4G pin of the public network communication system through resistor R9, the UART_RX_MCU pin of the low-power MCU system is connected in series with the UART_TXD_4G pin of the public network communication system through resistor R10, the WAKED_BY_MCU pin of the low-power MCU system 1 is connected in series with the WAKE_4G pin of the public network communication system 2 through resistor R11, and the WAKE_MCU pin of the low-power MCU system 1 is connected in series with the WAKED_BY_4G pin of the public network communication system 2 through resistor R12. The coordination control signal module 4 coordinates the wake-up pins of the low-power MCU system 1 and the public network communication system 2 to wake up the low-power MCU system 1 or the public network communication system 2 to work, thereby realizing the switching between the three modes of low-power MCU system 1 working independently, public network communication system 2 working independently, and low-power MCU system 1 and public network communication system 2 working.
[0034] The low-power MCU system 1 and the public network communication system 2 both include a communication protocol module and a driver module. The communication protocol module of the low-power MCU system 1 establishes a connection with the communication protocol module of the public network communication system 2, and the driver module of the low-power MCU system 1 establishes a connection with the driver module of the public network communication system 2.
[0035] According to the strategy, the communication protocol of the dual system is formulated. The communication protocol module includes communication protocols such as system liveness, data synchronization, scene synchronization, and APP UI synchronization. According to the communication protocol, the operating systems of the two main processing systems are optimized, and the relevant communication protocol modules (Protolol) and driver modules (Devicedriver) are added to the existing operating systems; then, according to the functions implemented by the two systems, the relevant MMI architecture is optimized, mainly by deleting unnecessary parts such as a large amount of UI on the public network communication module, and adding interfaces that require dual system coordination.
[0036] In terms of software, a strategy for the coordinated work of the two systems is formulated, and two working modes, power saving mode and full-function mode, are set. The system can work in the mode set by the user, or automatically switch the working mode according to the user's usage scenario. For example, when the user is in daily scenarios, the system works in power saving mode, and when the user is in special sports mode, the system switches to full-function mode. In power saving mode, only the low-power MCU system 1 works, and in full-function mode, the low-power MCU system 1 and the public network communication system 2 work at the same time.
[0037] Since the processing power and memory space of the ultra-low power MCU are very limited, the operating system used by this system must be deeply optimized to meet the needs of humanized MMI and UI. After the overall architecture is implemented, the system working strategy is optimized from the circuit and software to achieve optimal power consumption.
[0038] The system architecture of this device consists of a dual system consisting of a low-power MCU system 1 + a public network communication system 2 working together, plus various sensors, power management systems and protocol software for dual-system collaboration. This architecture perfectly solves the problems of the two popular structures currently in use. In this architecture, according to the user's work scenario, the two systems can be: 1. The low-power MCU system 1 works independently, and the public network communication system 2 is shut down; 2. The low-power MCU system 1 and the public network communication system 2 work at the same time; 3. The low-power MCU system 1 works, and the public network communication system 2 sleeps. The first working mode meets the basic sports and health needs of users and can have a long battery life; the second working mode, the two processing systems work independently, the system is in the maximum processing capacity mode, and at the same time meets the basic sports and health functions, and can also connect to the network to realize a large number of cloud-dependent applications. This mode consumes the most power; the third working mode provides applications and power consumption between the first and second modes. Users can set these three working modes to automatic switching or manual settings.
[0039] This device solves the problems of power management and dual-system coordinated working circuit logic through the circuit structure of the power supply system 3 and the coordinated control signal module 4; solves the problems of sensor data acquisition, PCB layout and coexistence of multiple antennas in the whole machine in structure through the dual-system collaborative work consisting of the low-power MCU system 1 + the public network communication system 2; solves the optimization problem of the RTOS running on the ultra-low power MCU in software by adding necessary software modules, deleting unnecessary software modules and optimizing certain functions in the low-power MCU system 1 and the public network communication system 2, solves the strategy and implementation protocol problems of the coordinated work of the dual systems in software, and realizes the contradiction between humanized MMI, UI and limited resources on the ultra-low power MCU; and solves the problem of power consumption optimization by modifying various applications at the self-operating system level.
[0040] The above contents are further detailed descriptions of the present invention in combination with specific preferred embodiments, and it cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the protection scope of the present invention.
