Abnormal warning method for handheld Bluetooth system and application Bluetooth system

The invention relates to a handheld Bluetooth system and a warning method for applying the Bluetooth system, in particular to a hand-held Bluetooth system capable of ranging and an abnormal warning method for a vehicle using the Bluetooth system.

Today's technology is changing day by day. For example, the key to a traditional vehicle is the mechanical opening of the vehicle's door or engine. However, the keys to today's vehicles are mostly inductive keys, when the user is near the vehicle. If the vehicle senses the inductive key, the door or engine of the locking vehicle can be opened by itself to reduce the trouble for the user to use the vehicle.

Moreover, today's inductive keys mostly use radio frequency (RF) technology or radio frequency identification (RFID) technology. Both of these technologies have two corresponding tags and identifiers. When the identifier senses the tag, the carrier can then open the door or engine of the locking carrier. However, both of these technologies are line of sight (LOS) technologies, so they are more susceptible to interference and increase user inconvenience.

In view of the above-mentioned problems of the prior art, one of the objects of the present invention is to provide a The handheld Bluetooth system and the application of the Bluetooth system have an abnormal warning method, so that the Bluetooth system has a fixed time transmission signal and a rangeable function, so as to enable the user to know the status of the vehicle in real time.

If “No”, it is judged whether the vehicle is in an abnormal state again. If “Yes”, the vehicle sends a warning signal, if the distance value is less than By setting the distance value, the handheld device sends a warning signal to alert the user.

Therefore, one of the features of the abnormality warning method for the Bluetooth system of the present invention is that, by applying the Bluetooth system, the abnormality warning method of the Bluetooth system of the present invention can increase the security and convenience of transmission and pairing.

The step of obtaining the distance between the carrier and the handheld device may further include the following steps: the first Bluetooth device transmits the ranging signal to the second Bluetooth device, so that the second Bluetooth device knows the ranging signal. Signal strength; the second Bluetooth device determines the distance between the carrier and the handheld device according to the signal strength; and the second Bluetooth device transmits the distance value to the first Bluetooth device, so that the first Bluetooth device knows the distance value .

Therefore, another feature of the distance warning method for applying the Bluetooth system of the present invention is that the distance value between the carrier and the handheld device is obtained by using the Bluetooth system.

The warning signal can be, for example, an optical signal, an audio signal, a vibration signal, a graphic signal, a text signal, an image signal or other signal that can alert the user.

The abnormal state may be, for example, a vibration or movement of the vehicle.

Wherein, when the distance between the vehicle and the user is less than the preset distance value, and the vehicle is in an abnormal state, the vehicle can transmit the status signal to the handheld device.

Therefore, another feature of the vehicle abnormal alarm method for applying the Bluetooth system of the present invention is that the state signal of the vehicle is transmitted to the handheld device, so that the user can immediately grasp the state of the vehicle.

After the handheld device receives the status signal, the command signal can be further transmitted to the vehicle, so that the vehicle issues or stops sending the warning signal.

In addition, when the Bluetooth system determines whether the vehicle is in an abnormal state, it may first determine whether the user's detection command is received, and if yes, determine whether the vehicle is in an abnormal state.

In addition, the Bluetooth system to which the present invention is applied may further have a memory unit, and the preset distance value may be stored, for example, in the memory unit.

In addition, the present invention further provides a handheld Bluetooth system for obtaining vehicles and hands. The distance between the devices is used to apply to the above method. Therefore, the handheld Bluetooth system of the present invention can include at least a Bluetooth transceiver and a processor. The Bluetooth transceiver is wirelessly coupled to the carrier by Bluetooth technology, and the Bluetooth transceiver is configured to receive the signal transmitted by the carrier. The processor is electrically connected to the Bluetooth transceiver.

Please refer to FIG. 1. FIG. 1 is a flow chart showing the steps of the Bluetooth system of the present invention for measuring a distance value to perform an action. As shown in FIG. 1, the present invention may first perform step 100, that is, set a preset distance value. For example, when the Bluetooth system is manufactured, the preset distance value is set, or the user can set the preset distance value by inputting the device. Next, step 200 can be performed, that is, the distance between the carrier and the handheld device is measured. The vehicle can be, for example, a two-wheeled vehicle, a four-wheeled vehicle or a carrier of two or more wheels. For example, the vehicle can be, for example, a passenger car, a truck, a bus, a tour bus, a locomotive, a bicycle, an electric vehicle, an ATV or Multi-purpose recreational vehicle. Also, the handheld device can be, for example, a cell phone or a key.

Continuingly, the present invention determines and obtains the distance between the carrier and the handheld device by using a Bluetooth system, and the Bluetooth system includes at least a first Bluetooth device and a second Bluetooth device, and the first Bluetooth device and the second device One of the Bluetooth devices is, for example, disposed on a carrier, and the other is disposed, for example, on the handheld device. And, the first Bluetooth device and the second Bluetooth device are paired with each other. Wherein, since any Bluetooth device has a unique address code, the two Bluetooth devices can be paired with each other so that the two Bluetooth devices are paired with each other. In addition, the first Bluetooth device and the second Bluetooth device can be connected to each other, for example, in a point-to-point manner, so that the third party can be transmitted when the data is transmitted, thereby increasing the security and convenience in transmission and pairing. In addition, the Bluetooth system can use the frequency hopping technology and encryption by the advanced encryption standard (AES-128) to further increase the security of transmission and pairing.

Please refer to FIG. 2, which is a flow chart of the steps of obtaining the distance value by the Bluetooth system of the present invention. As shown in FIG. 2, the present invention first performs step 201 when the distance value is obtained, that is, the first Bluetooth device transmits the ranging signal to the second Bluetooth device, so that the second Bluetooth device knows the signal strength of the ranging signal. . The first Bluetooth device and the second Bluetooth device transmit a signal to the other every interval time. Therefore, the signal can be used as a ranging signal. The interval time may be, for example, three seconds, five seconds, ten seconds, or other suitable time. In addition, the ranging signal can also be, for example, a signal with other information, or a signal for measuring the signal strength only for ranging. If the ranging signal is a signal with other information, after receiving the ranging signal, the second Bluetooth device can not only know the signal strength of the ranging signal, but also transmit other information in the ranging signal to and The second Bluetooth device is interconnected or the processor of the second Bluetooth device itself to further process the other information. In addition, the second Bluetooth device can use the signal strength measuring device to learn the ranging signal. Signal strength.

Then, when the second Bluetooth device receives the ranging signal and knows the signal strength of the ranging signal, step 202 can be performed, that is, the second Bluetooth device learns or determines the first Bluetooth according to the strength of the ranging signal. The distance between the device and the second Bluetooth device. For example, the second Bluetooth device can have a comparison table between the signal strength and the distance value. When the second Bluetooth device knows the signal strength, the second Bluetooth device can learn the corresponding distance value by looking up the table. Alternatively, the second Bluetooth device may have a linear or non-linear relationship function between the signal strength and the distance value. For example, after the second Bluetooth device learns the signal strength, the signal strength may be substituted into the relationship function. Calculating the distance value between the first Bluetooth device and the second Bluetooth device. Wherein, because one of the first Bluetooth device and the second Bluetooth device is located on the carrier and the other is located on the handheld device, the distance between the first Bluetooth device and the second Bluetooth device is equivalent to the carrier and the handheld device. The distance value of the device.

Continuing, after the second Bluetooth device knows the distance between the carrier and the handheld device, step 203 may be selectively performed, that is, the second Bluetooth device transmits the distance between the carrier and the handheld device to the first Bluetooth device. The distance value is known to both the first Bluetooth device and the second Bluetooth device. In addition, the second Bluetooth device and the first Bluetooth device can also transmit signals to each other by mutual signals, so that the first Bluetooth device and the second Bluetooth device can measure the signal strength of the signal, and further The distance between the vehicle and the handheld device is separately known or determined. Thereafter, the distance value can be further transmitted to another Bluetooth device, for example, to further confirm whether the distance value is incorrect. For example, if the difference between the distance values respectively learned by the first Bluetooth device and the second Bluetooth device is too large, step 200 may be performed again. On the other hand, if the distance values learned by the first Bluetooth device and the second Bluetooth device are similar or equal, the average of the two distance values may be taken. For the distance between the carrier and the handheld device, or one of the distance values may be the distance between the carrier and the handheld device. Wherein, the determination of whether the difference in distance values described herein is too large may be based on the application purpose of the distance value, and the value of the gap may be separately defined.

After determining the distance between the carrier and the handheld device, step 300 can be performed, that is, the distance value is compared. For example, in step 300, one or both of the first Bluetooth device and the second Bluetooth device may, for example, compare the preset distance value and the distance value between the carrier and the handheld device, or may, for example, Compare the distance values of the vehicle and the handheld device at different times. Moreover, whether step 300 compares the distance value with the preset distance value or compares the distance values at different times, a comparison result can be obtained. Then, one or both of the first Bluetooth device and the second Bluetooth device can perform the step 400 according to the comparison result, that is, perform an action. The action of the execution may be, for example, establishing a connection relationship between the first Bluetooth device and the second Bluetooth device, or may be, for example, alerting the user. In addition, the act of performing may also be, for example, transmitting a message to a carrier or handheld device whereby the carrier or handheld device turns on its particular function or turns off its particular function.

Therefore, because the Bluetooth device transmits a signal to another Bluetooth device that is paired with each other at an interval, the Bluetooth system can use the fixed transmission signal as the ranging signal to determine the relationship between the two Bluetooth devices. Distance value. In addition, the Bluetooth device can also specifically transmit a ranging signal to perform the action of measuring the distance value. The interval may be, for example, the time defined in the Bluetooth technology protocol (IEEE 802.15), and may be any time set by the user or the manufacturer, for example. For example, the interval time can be, for example, three seconds, five seconds, ten seconds, or other suitable time.

Please refer to Figure 3 to Figure 4, and Figure 3 is the Bluetooth Vehicle Control System of the present invention. The system block diagram of the system, and Fig. 4 is a system block diagram of the handheld Bluetooth system of the control vehicle of the present invention. The Bluetooth carrier control system and the handheld Bluetooth system may be paired with each other, for example, and one of them may be, for example, the aforementioned first Bluetooth device, and the other may be, for example, the aforementioned second Bluetooth device. As shown in FIGS. 3 to 4, wherein the Bluetooth carrier control system 500 can be located, for example, on a carrier, for example, the Bluetooth carrier control system 500 can be located, for example, in a vehicle rear view mirror, a front instrument panel, and a storage device. On the box or other device of the vehicle. Additionally, the handheld Bluetooth system 600 can be, for example, a key or built into a handheld device such as a cell phone. In addition, the present invention can provide power to the Bluetooth carrier control system 500 and the handheld Bluetooth system 600, for example, by a power supply method, for example, solar power supply, hydroelectric power supply, thermal power generation, and wind power generation. Power, battery, power or vibration generate electricity, wireless charging, or other means of generating electricity.

In other words, the Bluetooth carrier control system 500 can have, for example, a car Bluetooth device 510 and a vehicle control device 520 that are electrically connected to each other. The in-vehicle Bluetooth device 510 can include, for example, a Bluetooth transceiver 511, a processor 512, and a memory unit 513 and a warning device 514 electrically coupled to the processor 512. The vehicle control device 520 can be disposed, for example, on a carrier, and the vehicle control device 520 can include, for example, a carrier control unit 521 and an input device 522, an output device 523, and an imaging device electrically coupled to the vehicle control unit 521. 525. The Bluetooth transceiver 511 can wirelessly connect the external device by using Bluetooth technology, for example, to receive a signal transmitted by the external device. Moreover, the external device can be, for example, a handheld Bluetooth system 600 that is paired with the Bluetooth carrier control system 500. Further, the vehicle control unit 521 is disposed on the carrier and controls the carrier.

In addition, the processor 512 is electrically connected to the Bluetooth transceiver 511 and the vehicle control unit 521. . If the Bluetooth carrier control system 500 is the second Bluetooth system, when the Bluetooth transceiver 511 transmits the received signal to the processor 512, the processor 512 first measures the signal strength of the signal, and borrows The signal strength is used to determine the distance between the external device and the carrier. Next, the processor 512 compares the distance value with a preset distance value to obtain a comparison result. The preset distance value can be stored in the memory unit 513, for example, and the memory unit 513 is electrically connected to the processor 512 to provide the preset distance value to the processor 512. Alternatively, the vehicle control unit 521 can be electrically connected to the input device 522, for example, to allow the user to set a preset distance value by using the input device 522, and the preset distance value is further transmitted to the processor 512 via the vehicle control unit 521. . Furthermore, this preset distance value can be, for example, between about 1 meter and 100 meters.

After obtaining the comparison result of the distance values, the processor 512 can respectively transmit the motion signal to the vehicle control unit 521 and the external device by using the comparison result, so that the vehicle control unit 521 and the external device can use the motion signal to Perform an action. For example, when the comparison result is that the preset distance value is greater than the distance value between the carrier and the external device, the external device may establish a connection relationship with the vehicle control unit 521, for example, so that the vehicle control unit 521 controls the carrier selectivity. Take an action. Wherein, the action may be, for example, a function of opening, and the function may be, for example, an anti-theft system for releasing the vehicle, transmitting a vehicle signal to an external device, opening a device inside the carrier, unlocking the door or engine of the carrier, or , alert the user. In addition, when the vehicle is turned on, the vehicle can directly perform the corresponding function, or the open external device can selectively perform the corresponding function. For example, the vehicle control unit 521 can control the locking of the device inside the carrier to open the carrier, so that the external device can be coupled to the vehicle control unit 521 to open the device inside the carrier. In other words, if the vehicle is controlled When the function of the internal device of the unlocking device is not turned on, the external device cannot command the vehicle control unit 521 to turn on the device inside the carrier.

In addition, if the carrier is enabled to be controlled, the external device can establish a connection relationship with the vehicle control unit 521. After the external device is connected to the vehicle control unit 521, the vehicle control unit 521 can control the camera 525 to capture the image and transmit it back to the vehicle control unit 521, and then transmit it to the processor 512 of the Bluetooth device 510. The Bluetooth transceiver 511 is sent to the external device via the Bluetooth transceiver 511. In addition, if the action is to alert the user, the processor 512 can send an alert signal to the alert device 514 built in the Bluetooth device 510, for example, so that the alert device 514, such as a light-emitting component, emits light or flashes to alert the user. Alternatively, a warning device 514, such as a sound component, is sounded to alert the user. In addition, the processor 512 can also send an alert signal to the vehicle control unit 521, for example, after receiving the warning signal, the vehicle control unit 521 sends the warning signal to the output device 523, so that the output device 523 outputs the warning signal. The warning signal can be, for example, an audio signal, a light source signal, or a screen displayed on the output device 523.

In addition, the handheld Bluetooth system 600 can be disposed in a handheld device such as a mobile phone or a key, and the handheld Bluetooth system 600 can include, for example, a Bluetooth transceiver 601, a processor 602, and a memory unit electrically coupled to the processor 602. 603. Input device 604 and output device 605. The Bluetooth transceiver 601 can be wirelessly coupled to the carrier by, for example, Bluetooth technology to receive a signal transmitted by the carrier. Also, the carrier can have, for example, a Bluetooth carrier control system 500 that is paired with the handheld Bluetooth system 600.

In addition, the processor 602 is electrically connected to the Bluetooth transceiver 601. If the handheld Bluetooth system 600 is the second Bluetooth device, when the Bluetooth transceiver 601 transmits the received signal to the processor 602, the processor 602 first Measure the signal strength of this signal And by the intensity of the signal, the distance between the handheld device and the carrier is known. Next, the processor 602 compares the distance value with a preset distance value to obtain a comparison result. The preset distance value may be stored in the memory unit 603, for example, when the processor 602 needs to compare the distance value with the preset distance value, the memory unit 603 provides the preset distance value to the processor 602. Alternatively, the user is allowed to set the preset distance value by using the input device 604, and the preset distance value is further transmitted to the processor 602 via the input device 604. Wherein, the preset distance value may be, for example, between about 1 meter and 100 meters.

After obtaining the comparison result of the distance values, the processor 602 further compares the result, for example, respectively, transmitting the motion signal to the vehicle and the output device 605, so that the vehicle performs an action by using the motion signal, or the output device. The 605 outputs a warning signal or other signal by means of the action signal. For example, when the comparison result is that the preset distance value is greater than the distance between the handheld device and the carrier, the handheld device can establish a connection relationship with the carrier, for example, to control the vehicle to perform an action, or can control the load. With a function to open. The action or function may be, for example, the anti-theft system of the vehicle, the transmission of the vehicle signal to the handheld device, the opening of the device inside the vehicle, or the unlocking of the vehicle door or engine. In addition, the processor 602 can also send an alert signal to the output device 605, for example, to cause the output device 605 to illuminate, flash, emit a sound, display a graphic, display text, display an image, or vibrate to alert the user. In addition, the output device 605 can also output an alert signal to alert or alert the user. The output device 605 can be, for example, a light source, a speaker, a screen, a vibration device, or a combination of the above components. Also, the screen can display, for example, graphics, text, images, or other objects that can be displayed on the screen.

Please refer to Figure 5, Figure 5 is the abnormality of the vehicle used in the Bluetooth system of the present invention. A flow chart of the implementation steps of the first embodiment of the warning method. As shown in FIG. 1 to FIG. 5, the Bluetooth system to which the present invention is applied may include a first Bluetooth device and a second Bluetooth device, and one of the first Bluetooth device and the second Bluetooth device is disposed on the carrier. The other is placed on the handheld device and the user carries the handheld device. Therefore, when the user is not located on the vehicle, if the vehicle is in an abnormal state such as vibration or movement, the vehicle can issue a warning signal, and when the distance between the user and the vehicle is within a preset distance value In the meantime, the present invention can actively alert the user by the Bluetooth system in the handheld device, so that the user can immediately know the status of the vehicle.

In other words, the vehicle abnormal alarm method of the Bluetooth system of the present invention is configured to set a preset distance value in step 100, and the preset distance value is used as a reference distance value when the user and the vehicle are used. When the distance value is less than the preset distance value and the vehicle is in an abnormal state, the present invention can alert the user by the handheld device. In addition, the vehicle abnormality warning method of the present invention can determine and obtain the distance value between the vehicle and the user carrying the handheld device in step 200, and then compare the measured distance value and the preset value in step 300. Set the distance value to get a comparison result. The comparison result may be, for example, that the distance value is greater than a preset distance value or less than a preset distance value. Or, the vehicle abnormality warning method of the present invention performs the step 200 at intervals of time to obtain the distance between the vehicle and the user. Therefore, the vehicle abnormality warning method of the present invention may also be in step 300. Compare the distance between the vehicle and the user obtained at different times to obtain a comparison result. The comparison result may be, for example, a distance value obtained by the current distance different from the previous time or a distance value obtained from the previous time.

Thereafter, the vehicle abnormality warning method of the present invention may perform different actions in step 400 according to different comparison results of step 300. For example, when comparing results When the distance value obtained is greater than the preset distance value, the vehicle can issue a warning signal if the vehicle has an abnormal state. When the comparison result is that the obtained distance value is less than the preset distance value, if the vehicle has an abnormal state, not only the vehicle can issue a warning signal, but the handheld device can also issue a warning signal to alert the user. In addition, when the comparison result is that the distance value obtained now is different from the previously obtained distance value, the handheld device may also issue a warning signal to alert the user. In other words, the vehicle abnormal alarm method of the Bluetooth system of the present invention immediately alerts the user when the vehicle is in an abnormal state.

In detail, as shown in FIGS. 3 to 5, the vehicle abnormality warning method of the present invention using the Bluetooth system can determine whether the vehicle is abnormal, for example, by using the vehicle control unit 521 in the Bluetooth carrier control system 500. State (step 421), wherein the abnormal state can be, for example, a vibration of the carrier, a movement of the carrier, or other abnormal condition. If the vehicle does not have an abnormal state, the vehicle abnormality warning method of the present invention may repeat step 421. When the vehicle control unit 521 determines that the vehicle has an abnormal state, the vehicle can issue a warning signal (step 432), and at the same time or after, the processor 512 and the processor 602 can obtain the vehicle and carry the vehicle. The distance value between the users of the handheld device and determining whether the distance value is less than the set preset distance value (step 331). For example, the preset distance value may be stored in the memory unit 513 or the memory unit 603 in advance, or the user may use the input device 522 or the input device 604 to set the preset distance value in advance. And, the preset distance value may be, for example, between about 10 meters and 100 meters.

In other words, when the distance between the vehicle and the user is greater than the preset distance value and the vehicle is in an abnormal state, the vehicle can not only issue an alert signal by the output device 523 (step 432), but also can start the camera. Device 525 captures the image. The output device 523 can be, for example, a light-emitting element or a sound element, and the light-emitting element can be, for example, a lamp or a lamp. For a bubble or light emitting diode, the sound element can be, for example, a horn or an alarm. The warning signal can be, for example, an optical signal, an audio signal, a vibration signal or other signal that can be used as a warning.

In addition, when the distance between the vehicle and the user is less than the preset distance value and the vehicle is in an abnormal state, not only the vehicle can issue a warning signal, but the handheld device can also be used by the output device 605 of the handheld Bluetooth system 600. A warning signal is issued to alert the user (step 433). Similarly, the vehicle control unit 521 can activate the camera 525 to capture images. The handheld device can be, for example, a key or mobile phone provided with a handheld Bluetooth system 600, and the output device 605 can be, for example, a screen, a light emitting element, or a sound component. Moreover, the illuminating element can be, for example, a light bulb, a light emitting diode or other illuminating element, and the sound element can be, for example, a horn or other audible element. In addition, the warning signal can be, for example, an optical signal, an audio signal, a vibration signal, a graphic signal, a text signal or an image signal.

For example, the handheld Bluetooth system 600 disposed in the handheld device can include, for example, a Bluetooth transceiver 601, a processor 602, and an output device 604. Therefore, the abnormality warning method of the present invention can be wirelessly connected to the Bluetooth transceiver 511 on the carrier by using the Bluetooth transceiver 601. The Bluetooth transceiver 601 is configured to receive the Bluetooth signal transmitted by the Bluetooth transceiver 511. Then, when the Bluetooth transceiver 601 transmits the Bluetooth signal to the processor 602, the processor 602 measures the signal strength of the Bluetooth signal to obtain the distance between the handheld device and the carrier by using the signal strength, and compares the value. The distance value is compared with a preset distance value to obtain a comparison result. When the vehicle has an abnormal state, and the comparison result is that the distance value is less than the preset distance value, the output device 604 sends a warning signal according to the comparison result to alert the user.

In addition, when the vehicle is in an abnormal state, and the distance between the user and the vehicle is less than When the distance value is preset, the Bluetooth carrier control system 500 on the carrier can transmit a status signal to the Bluetooth transceiver 601 located on the handheld device via the Bluetooth transceiver 511 (step 434). After the Bluetooth transceiver 601 receives the status signal, the status signal can be displayed on the output device 605 in the handheld device, for example, by the processor 602. The status signal can be, for example, the status of the vehicle, or the status signal can be, for example, an image captured by the camera 525.

Then, after the user sees the status signal displayed on the output device 605, the handheld Bluetooth system 600 and the Bluetooth carrier control system 500 can further transmit the command signal to the carrier to enable the output device on the carrier. 523 issues or stops issuing a warning signal (step 435). In addition, when the output device 523 issues an alert signal, the Bluetooth carrier control system 500 on the carrier can continuously transmit the status signal to the handheld Bluetooth system 600 disposed on the handheld device, thereby providing the user with continuous knowledge of the carrier. status. When the vehicle returns from the abnormal state to the non-abnormal state, the user can, for example, transmit a command signal to the carrier to cause the output device 523 to stop issuing the warning signal.

Therefore, one of the features of the abnormality warning method for the Bluetooth system of the present invention is that the Bluetooth system determines whether the distance value is less than the preset distance value and determines whether the vehicle is in an abnormal state, so that the user can immediately know the load. With the status.

In addition, please refer to FIG. 6 , which is a flow chart of the implementation steps of the second embodiment of the vehicle abnormal alarm method of the Bluetooth system according to the present invention. The second embodiment is a warning method when the abnormal state is the movement of the carrier. As shown in Figures 3, 4 and 6, the vehicle abnormality warning method of the present invention first utilizes the Bluetooth vehicle control system 500 and the handheld Bluetooth system 600 to obtain the distance value between the vehicle and the handheld device (step 240). And determining whether the distance value is less than a preset distance value (step 331). Wherein, when the handheld Bluetooth system 600 obtains the distance between the carrier and the handheld device, This distance value can be stored, for example, in the memory unit 603.

In other words, when the distance value is greater than the preset distance value, the handheld Bluetooth system 600 can again obtain the distance value between the vehicle and the handheld device after an interval of time. When the distance value is less than the preset distance value, the handheld Bluetooth system 600 can determine whether a detection command issued by the user is received (step 441). The user can input the detection command to the handheld Bluetooth system 600 by using the input device 604, for example. When the handheld Bluetooth system 600 does not receive the detection command, the handheld Bluetooth system 600 can be in a standby state. When the handheld Bluetooth system 600 receives the detection command, it determines whether the distance value between the carrier and the handheld device changes (step 332).

In particular, the processor 602 can determine the distance between the Bluetooth carrier control system 500 and the handheld Bluetooth system 600, for example, by the Bluetooth carrier control system 500 transmitting signals to the handheld Bluetooth system 600. Because the Bluetooth carrier control system 500 is disposed on the carrier and the handheld Bluetooth system 600 is disposed on the handheld device, the processor 602 can know the distance between the carrier and the handheld device. And because the Bluetooth carrier control system 500 transmits a message to the handheld Bluetooth system 600 at intervals, the processor 602 can determine whether the distance value changes according to the distance value determined at different time points. It is used to know if the vehicle is in a moving state.

When the distance between the carrier and the handheld device does not change, i.e., the carrier is in a stationary state, the processor 602 can, for example, wait for at least one interval to perform step 332 again. When the distance between the carrier and the handheld device changes, the handheld device can send a warning signal to the user via the output device 605 (step 433), so that the user knows that the carrier is in a moving state. The warning signal can be, for example, an optical signal, an audio signal, a vibration signal, a graphic signal, a text signal or an image signal. In addition, the Bluetooth carrier control system 500 on the carrier can also transmit The status signal of the carrier is sent to the handheld Bluetooth system 600 of the handheld device (step 434), so that the user can immediately grasp the status of the vehicle. The status signal can be, for example, an image captured by the camera 525. After the user knows the status of the vehicle by using the handheld device, the command signal can be transmitted to the Bluetooth carrier control system 500, for example, so that the vehicle sends or stops the warning signal (step 435).

Therefore, one of the features of the vehicle abnormal alarm method for applying the Bluetooth system of the present invention is that the user is alerted by the warning signal sent by the handheld device, so that the user knows that the vehicle is in an abnormal state.

Another feature of the vehicle abnormal alarm method for applying the Bluetooth system of the present invention is that the state signal of the vehicle is transmitted to the handheld device, so that the user can immediately grasp the state of the vehicle.

In summary, the abnormality warning method for the Bluetooth system of the present invention transmits the signal and the rangeable characteristics at intervals of the Bluetooth system, so that the user can immediately when the vehicle is in an abnormal state. Know the status of the vehicle.

The above is intended to be illustrative only and not limiting. Any equivalent modifications or alterations to the spirit and scope of the invention are intended to be included in the scope of the appended claims.
