The working principle of the multimode super-regenerative awakening device with ultra-low power consumption is as follows: as shown in fig. 2, in the present application, there are a wake-up antenna 1 and an acquisition module 2, wherein acquisition signals of the acquisition module 2 can also enable a super-regenerative receiver 3 to generate a wake-up instruction, the conventional super-regenerative receiver 3 can only receive antenna signals of the wake-up antenna 1, and the present application also has acquisition signals of the acquisition module 2, and there are multiple working modes in the present application, which can be a wake-up instruction mode generated by the super-regenerative receiver 3 when only receiving antenna signals; the super regenerative receiver 3 can also generate a wake-up instruction mode when only the acquisition signal is received; it is also possible to have a mode in which the super regenerative receiver 3 generates a wake-up command no matter whether an antenna signal or a pickup signal is received; it may also be a mode in which the antenna signal and the acquisition signal need to be received simultaneously in order for the super regenerative receiver 3 to generate a wake-up command.

No matter which kind of mode, super regenerative receiver 3 begins default to the dormant state, after the instruction is awakened in the generation, will awaken the instruction and send to main transceiver 5 to awaken main transceiver 5, when main transceiver 5 need not the during operation in a period of time, can generate out control signal, central control module 4 will extinguish control signal and send to super regenerative receiver 3, make super regenerative receiver 3 get into the dormancy.

in the fourth operation mode, the wake-up antenna 1 and the acquisition module 2 operate simultaneously, and both must generate an activation signal simultaneously to wake-up the receiver.

The gravity sensor, the acceleration sensor, the angle sensor, the angular acceleration sensor and the like are all microelectronic components with low power consumption essentially, and also all output digital signals, and all the components can play a role in connecting and awakening a receiver. However, the angular sensor and the angular acceleration sensor are relatively bulky and consume relatively high power compared to the gravity sensor and the acceleration sensor.

For example, the gravity sensor may collect changes in the gravity environment to generate a digital signal, and the super regenerative receiver 3 receives the digital signal from the gravity sensor to obtain a wake-up command and transmit the signal to the wake-up controller. Therefore, the super regenerative receiver 3 in the present application can receive an external wireless signal and transmit the external wireless signal to the wake-up control module to determine whether to wake up the host, and the gravity sensor can also sense the change of the external gravity environment to generate an electrical signal and transmit the electrical signal to the wake-up control module to determine whether to wake up the host.

In some embodiments, the present application further comprises:

the charging module is used for providing electric energy for the awakening device;

the charging module adopts magnetic attraction type charging.

As a specific embodiment, as shown in fig. 2, the working flow of the ultra-low power consumption multimode super-regenerative wake-up device provided by the present application is as follows:

1, the defaults of the awakening device are in a gravity sensing mode, the gravity sensor with ultra-low power consumption and the awakening receiver with the crystal oscillator as the core work normally, and other modules are in a dormant state.

And 2, after the gravity sensor is influenced by the environment to generate a change value, transmitting the change value to the awakening receiver, and judging whether the awakening signal is filtered by an awakening controller of the awakening receiver.

3, if the wake-up signal needs to be filtered, the wake-up signal is masked. According to the time interval, multiple awakening signals within M minutes from the last awakening command response are shielded, so that continuous energy-consuming work of the awakening device is avoided, and long endurance is ensured.

4, if the wake-up signal does not need to be filtered, the wake-up signal is immediately transmitted to the host computer, and then the information is transmitted to the specified server.

And 5, the host can select a working mode in a working state, a new working mode takes effect immediately after the working mode is selected, and an M value for controlling the time interval of the filtration awakening signal of the awakening device and a dormant counting X value can be set.

6, repeating the above process.

The application has the following beneficial effects:

(1) According to the method and the device, through selection of the working mode and the filtering measure of the awakening controller, redundant awakening signals of the host are shielded, and the host is prevented from being frequently awakened and continuously working to consume a large amount of power. The simple data transmission mode ensures that the background can obtain the key information without more data storage and analysis.

(2) The unit of this application normalizing work is gravity sensor or the super regenerative receiver 3 who uses crystal oscillator as the core, and the power consumption is below 3mw, and the ultra-low power consumption configuration. The communication time of the host is reasonably limited, and the host automatically enters the sleep mode. The working time of the host is relatively short, and the energy consumption is greatly reduced.

(3) The device has the basis of low-power consumption, and under the condition that most demands are met, the volume is subjected to limit compression, the device is a cylinder, the diameter can be limited to be below 30mm, and the height is limited to be below 15 mm. The cylindrical design is easier to adapt to more application scenes.

As shown in fig. 3, an embodiment of the present application provides an operating method of an ultra-low power consumption multimode ultra-regenerative wake-up device, including:

determining the operating mode of the super regenerative receiver 3; the working modes comprise an independent working mode of the awakening antenna 1, an independent working mode of the acquisition module 2, an independent working mode of the awakening antenna 1 or the acquisition module 2 and a common working mode of the awakening antenna 1 and the acquisition module 2;

when the working mode is the single working mode of the awakening antenna 1, the acquisition module 2 is in a dormant state, and when an antenna signal is received, an awakening instruction is generated;

when the working mode is the independent working mode of the acquisition module 2, the awakening antenna 1 is in a dormant state, and when a gravity signal is received, an awakening instruction is generated;

when the working mode is the single working mode of the awakening antenna 1 or the acquisition module 2, an awakening instruction is generated no matter an antenna signal or a gravity signal is received;

when the working mode is a common working mode of the awakening antenna 1 and the acquisition module 2, the antenna signal and the gravity signal are received simultaneously within a first preset time threshold, and an awakening instruction is generated.

Preferably, after the wake-up command is generated, the wake-up command generated within a second preset time threshold is filtered, and the response to the wake-up command generated within the second preset time threshold is prohibited.

Specifically, when the acquisition module 2 is assumed to be a gravity sensor, the working process of the working method of the application is as follows:

if the central control module 4 selects the independent working mode of the awakening antenna 1, the gravity sensor processes the dormant state at the moment, and the awakening controller receives an awakening instruction for awakening the antenna 1, so that the awakening instruction can be determined; if the gravity sensor single working mode is selected through the central control module 4, the awakening antenna 1 does not work at the moment, and the awakening controller receives an awakening instruction of the gravity sensor, so that the awakening instruction can be determined; if the central control module 4 selects an OR mode in which the gravity sensor and the awakening antenna 1 work simultaneously, the gravity sensor and the awakening antenna 1 can work at the moment, and the awakening controller receives an awakening instruction of any one of the gravity sensor and the awakening antenna 1 to determine the awakening instruction; if the 'just' mode that the gravity sensor and the awakening antenna 1 work simultaneously is selected through the central control module 4, both the gravity sensor and the awakening antenna 1 can work at the moment, but the awakening controller must receive awakening instructions of the gravity sensor and the awakening antenna 1 at the same time within a certain time to determine the awakening instruction;

according to the method, a wake-up controller calculates according to the time of a crystal oscillator, performs signal filtering within N hours from an effective wake-up instruction, filters all wake-up instructions, and responds to the wake-up instruction after the time is longer than N hours;

after the wake-up command is confirmed, the crystal oscillator changes the operation mode into a constant oscillator mode, continuously generates a stable reference clock signal, and activates the main transceiver 5 to work.

After the host is finished, the central control module 4 controls to enter the dormancy state and wait for the next awakening instruction.

The last process is circularly repeated.

In summary, the present application provides an ultra-low power consumption multimode super-regenerative wake-up device and a working method thereof, which have the following beneficial effects:

(1) The super-regenerative receiver only needs 1 crystal oscillator, so that the redundancy of hardware is reduced, and enough space is reserved for other important components.

The coverage rate of the wireless signal is large, and the awakening device is activated under the environment covered by the wireless signal, so that the requirements for intensive terminal use scenes are difficult to meet, but the control cannot be performed. At this time, the gravity sensor mode can be used for compensation, or the wireless signal and the gravity sensor are effective at the same time, and the host can be activated through the wake-up controller. The method and the device reduce the interference possibly brought by the super-regenerative receiver to a certain extent.
