Description of the Invention: [Technical Field] The present invention relates to a Bluetooth device, and more particularly to a Bluetooth device and method for automatically detecting and de-energizing power. [Prior Art] With the rapid development of modern technology, wireless communication technology has developed rapidly. Among them, Bluetooth (Bluet00th), a low-cost, low-power short-range wireless communication technology has been widely used, such as mobile phones, earphones, personal digital assistants, and computers. Peripheral accessories such as keyboards and mouse electronic devices, as long as the built-in Bluetooth chip is built in, can freely communicate with the corresponding device to wirelessly transmit data. The Bluetooth device is divided into a transmitting signal terminal and a receiving signal terminal, and the two are paired into one group, and the transmitting signal terminal continuously transmits the radio signal, and the receiving signal terminal starts after the steps of searching, pairing, connecting with the transmitting signal end, and the like. Receive the radio signal sent by the sending signal terminal. The portable Bluetooth device mostly uses the battery as its power source. The traditional Bluetooth device must be manually operated to turn off the power. Otherwise, it can only decide whether to enter the standby power saving mode according to the contact status of the radio signal. The method is as shown in the first figure. As shown, after the signal contact is disconnected, the Bluetooth device stops receiving the signal as in step S10, and automatically enters the standby mode (Stand-by Mode) as in steps S12 to S14, interrupting the connection between the Bluetooth device and the transmitting signal terminal. Although the Bluetooth device can automatically enter the standby mode when there is no signal or the connection is disconnected. When the extension signal is sent continuously, it does not mean that the gallbladder is still using the Bluetooth device. The user is most likely to put the Bluetooth device on hold. The action of turning off the power is not taken, but the signal is still transmitted and received. If the user forgets to turn off the power after suspending the use of the Bluetooth device, when the user wants to use the Bluetooth device next time, it is often found that the power has been exhausted, and the 5 200819968 duration of the Bluetooth device is considered to be extremely short. Or think that there is a leakage. Some of the existing Bluetooth devices, such as the Bluetooth mouse and keyboard, use the user's tap buttons, touch detection, etc., to let the Bluetooth device enter standby or stop state, but this must rely on the user similar Whether the action of tapping the keyboard or button occurs to detect. Many Bluetooth products cannot rely on the initiative of such users to determine. In view of the above, the present invention proposes a Bluetooth device and method for automatically sensing and powering off in response to the above-mentioned prior art regarding the lack of wasted power, so as to effectively overcome the above problems. SUMMARY OF THE INVENTION The main object of the present invention is to provide a method for automatically sensing and powering down a Bluetooth device, which utilizes induction technology without relying on a user to tap the keyboard or press the Anopheles side to make the Bluetooth device. In the non-use state, the power is automatically cut off or the power saving mode is entered to save power. Another object of the present invention is to provide a Bluetooth device for automatic sensing and power-off, which utilizes a sensing unit to actively sense the physical movement or temperature change of the Bluetooth device, which is different from the general Bluetooth device according to the radio wave. Whether the signal and the Bluetooth agreement are based on the _judgment basis, and whether the Bluetooth device is in the position of the service, and the power is saved or saved, saving power consumption. The Bluetooth device and method for self-destruction and power-off, even if the user forgets to turn off the blue power supply when the user leaves, the Bluetooth device will automatically detect the non-use state and automatically enter the standby mode or the shutdown program. Avoid running out of power in the Bluetooth device. For the above purposes, the present invention provides a Bluetooth device for automatic sensing and power-off, which is searched, paired and started to operate after the connection with the "second Bluetooth", receiving radio 峨, I from 6 200819968 motion sensing And the Bluetooth device for powering down includes a signal receiving port for receiving a radio port from the second Bluetooth device; a sensing unit for sensing ambient environmental changes and sending an electric signal; and a logic determining unit It is set in the __ Bluetooth chip, receives the voltage signal and judges the I device, and uses the sorrow to decide to continue receiving the radio signal, automatically shut down or enter the power saving state. The method for automatically sensing and powering off the Bluetooth device provided by the present invention comprises the following steps: - The Bluetooth device starts to receive the receiving radio signal after searching, pairing and connecting with the second Bluetooth device, _Blue The sensing unit is configured to sense the surrounding environment and send the signal to the Bluetooth device; and the logic determining unit uses the voltage signal to determine the blue status of the blue device. Choose to continue receiving radio signals, automatically shut down, or enter a power saving state. The details, technical contents, features, and effects achieved by the present invention will become more apparent from the detailed description of the embodiments. [Embodiment] The present invention provides a self-distracting power device and a method thereof, which are portable devices such as earphones, mobile phones, keyboards, and caps that use a battery as a power source. A state, and in the non-employed rider self-riding standby standby or shut down to save power and achieve power saving purposes. The Bluetooth device for automatic sensing and power-off provided by the present invention is constructed as shown in the first figure, and includes a signal receiver 12, a Bluetooth chip 14, a sensing unit 6 and a logic determining unit 18. The signal receiver 12 receives the number of the power transmission m sent from the other Bluetooth device, and transmits the radio to the material 14 to drive the device (1) to operate; sensing 7 200819968 unit 16 for sensing The surrounding environment of the Bluetooth device 10 changes, such as whether it is moving or changing temperature, and sends a voltage signal to the Bluetooth chip 14, and the logic determining unit 18 in the Bluetooth chip 14 according to the voltage signal sent by the sensing unit 16 Determine the use status of the Bluetooth device to determine whether to continue receiving radio signals, automatically shut down or enter a power-saving state. The power-saving state is standby mode. For example, when the RFMD SiW3500 model is in standby mode, the current loss is about 4 〇uA, which is 0.08% of the current consumption in the normal working mode. The second figure is a flow chart of the automatic sensing and power-off of the Bluetooth device provided by the present invention, as shown in the figure, when the Bluetooth device is in use, Will continue Receiving the radio signal sent by the Bluetooth device from the transmitting signal end, and the sensing unit senses that the Bluetooth device is in use, and also sends a voltage signal to the Bluetooth chip, as shown in step S2, to notify the Bluetooth chip. The Bluetooth device is in use. The sensing unit changes the ambient environment through the sensing in step S22. The environmental changes include physical sensing, such as vibration detection, level detection, acceleration detection and pressure detection, or other temperature. Sensing, body temperature (4), voltage change, current change, etc. When the Bluetooth device is in use, the sensing unit outputs a voltage signal to the logic judgment unit in the Bluetooth chip, so that the Bluetooth chip can judge the Bluetooth The device is in a position to repeat the step (10); conversely, when the (4) device is stationary, as in step SM, the sensing unit outputs a separate tank, thereby informing that "the standby mode is entered. Although the sensing unit stops outputting the voltage signal at step S24, once the step of step milk is determined to start the system, the reward step (10) takes a voltage signal to the blue crystal; ^; if the blue bud After the crystal segment time does not receive the voltage signal, it is judged that the Bluetooth device is in a non-use state, the Bluetooth device stops receiving the radio signal, and enters the standby mode (Stand_by MGde) as described in step gamma to save unnecessary power consumption. Bluetooth device 8 200819968 After entering the standby mode, Bluetooth # will still hold the test _ unit is to touch the voltage signal, if the Bluetooth device starts to use, the ship leaves the standby mode, returns to the step gamma, the sensing unit rotates The voltage signal is given to the Bluetooth chip; on the contrary, if the Bluetooth device enters the standby mode in step S26, after the preset time period of the system is not transmitted to the Bluetooth chip, the job chip will enter the shutdown process. ' Turn off the power of the Bluetooth device to avoid unnecessary power consumption. Therefore, when the sensing unit senses (4) that the device changes the temperature of the _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Static, immediately output the corresponding voltage signal to the bud film, so that the blue m is sent out into the standby mode command 1 if the Bluetooth device is in use, it can also go through the standby mode step, directly blue Lied down. In summary, the present invention provides a Bluetooth device and method for automatically sensing and powering off, in which a built-in sensing unit is used to sense the state of use of the Bluetooth device, and by different = The transmission of the watch number _ _ _ device _ make money or _, from the resident = under the age of the film into the standby mode of the nuclear wealth, so that the blue is placed in the non-money state w power, step-by-step to avoid users When you leave, you forget the power of the power supply. The above is only the preferred embodiment of the invention and is not intended to limit the implementation of the invention.
