The invention relates to a Bluetooth carrier control system and a method for applying the Bluetooth system to perform an action, in particular to a Bluetooth range control system capable of ranging and a Bluetooth system for managing a short-distance carrier.

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 addition, if you need to be at different distances Different connection relationships are carried out under the conditions, and today's technologies require different connected devices to carry out different connection relationships, which will increase the cost of use and space for use.

Wherein, after the Bluetooth system determines that the distance value is greater than the first preset distance value, it may first determine whether the distance value is less than the second preset distance value, and if so, the vehicle is enabled to enable the second function.

Therefore, one of the methods of the present invention for applying a Bluetooth system to manage a short-range vehicle is to enable the method of the present invention to increase the security and convenience of transmission and pairing by applying a Bluetooth system.

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. And, handheld The 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, for example, a signal strength measuring device to know the signal strength of the ranging signal.

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. Conversely, if the first Bluetooth device and the second Bluetooth device When the respective distance values are approximate or equal, the average value of the two distance values may be the distance between the vehicle 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 intervals, the Bluetooth system can determine the distance between the two Bluetooth devices by using the fixed transmission signal. 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 FIG. 4 to FIG. 5, FIG. 4 is a system block diagram of the Bluetooth carrier control system of the present invention, and FIG. 5 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 Figures 4 to 5, 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 carrier 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 enable the external device to be connected. The knot control unit 521 is used to open the device inside the carrier. In other words, if the vehicle control unit 521 does not turn on the function of unlocking the internal device of the carrier, 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 include, for example, a Bluetooth transceiver 601, a processor 602, and a memory unit 603, an input device 604, and an output device 605 that are electrically coupled to the processor 602. 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 3, and Figure 3 is the application of the Bluetooth system of the present invention to manage the close range. Flowchart of the implementation steps of the method of the vehicle. As shown in FIG. 1 to FIG. 5, the method for applying a Bluetooth system to manage a short-distance carrier of the present invention is, for example, first setting a first preset distance value and a second preset distance value in step 100, wherein the first The preset distance value is smaller than the second preset distance value. Next, the distance value between the carrier and the handheld device is measured and obtained in step 200, and then the measured distance value and the first preset distance value and the second preset distance value are compared in step 300 to obtain A comparison of the results. The comparison result is that the distance value is greater than the second preset distance value, and the distance value is between the first preset distance value and the second preset distance value or the distance value is less than the first preset distance value. Finally, different actions are performed in step 400 in accordance with the comparison results of step 300. For example, when the comparison result is that the distance value is greater than the second preset distance value, the Bluetooth device transmits a message to another Bluetooth device that is paired with each other at intervals, so the action is performed. For example, the vehicle may be in a waiting state. When the comparison result is that the distance value is between the first preset distance value and the second preset distance value, the action performed may open the second function for the vehicle, for example. In addition, when the comparison result is that the distance value is less than the first preset distance value, the action performed may, for example, turn on the first function for the vehicle.

In detail, the method for applying the Bluetooth system to manage the short-distance carrier of the present invention may, for example, first perform step 210, that is, obtain the first preset distance value, the second preset distance value, and the distance between the carrier and the handheld device. . For example, step 210 may, for example, first perform step 100 to set a preset distance value, and the preset distance value may be, for example, a first preset distance value and a second preset distance value, and the second preset distance value is Greater than the first preset distance value. The first preset distance value and the second preset distance value may be stored in the memory unit 513 of the in-vehicle Bluetooth device 510, for example, or may be set by the user using the input device 522 of the vehicle control device 520. For this first preset distance value and The second preset distance value. In addition, one of the first preset distance value and the second preset distance value may be stored in the memory unit 513 of the in-vehicle Bluetooth device 510, for example, and the user may use the input device 522 to set the other. In addition, the second preset distance value may be, for example, between about 50 meters and 60 meters, and the first preset distance value may be, for example, between about 2 meters and 3 meters.

After or at the same time as step 100, step 200 can be performed, for example, by processor 512 of in-vehicle Bluetooth device 510 to determine the distance between the carrier and the handheld device. The carrier can be, for example, a two-wheeled vehicle, a four-wheeled vehicle or a carrier of two or more wheels, and the handheld device can be, for example, a mobile phone or a key. In particular, the handheld device can have, for example, a handheld Bluetooth system 600, and the carrier can have, for example, a Bluetooth carrier control system 500, and the Bluetooth carrier control system 500 and the handheld Bluetooth system 600 are paired with each other. Therefore, the Bluetooth transceiver 601 of the handheld Bluetooth system 600 can, for example, transmit a signal to the Bluetooth transceiver 511 of the Bluetooth carrier control system 500. When the Bluetooth transceiver 511 receives the signal, the signal is transmitted to the processor 512. The signal may be, for example, a signal transmitted by the Bluetooth system at intervals, or specifically a ranging signal or a connection request signal. Thereafter, the processor 512 determines the distance between the carrier and the handheld device based on the signal strength of the signal. The processor 512 can then transmit the distance value to the Bluetooth transceiver 601 of the handheld Bluetooth system 600 via the Bluetooth transceiver 511. If the Bluetooth transceiver 601 receives the distance value, the Bluetooth transceiver 601 transmits the distance value to the processor 602, so that both the Bluetooth carrier control system 500 and the handheld Bluetooth system 600 know the distance value.

Then, after obtaining the distance value, the first preset distance value and the second preset distance value, the processor 512 performs step 311, that is, determines whether the learned distance value is smaller than the first preset distance value, and if so, proceeds Step 411, that is, the vehicle is turned on for the first function; If not, proceed to step 412 to enable the vehicle to turn on the second function, and when the vehicle is in the state of turning on the first function, the vehicle can be again turned off. For example, in step 411, the processor 511 can transmit a notification signal to the handheld Bluetooth system 600 and the vehicle control unit 521, so that the vehicle control unit 521 controls the carrier to enable the first function, thereby enabling the user to borrow The handheld Bluetooth system 600 controls the actions of the vehicle to perform the functions that are turned on. At this time, the handheld Bluetooth system 600 can send a link request signal, for example, and the processor 511 transmits the link request signal to the vehicle control unit 521, and replies a confirmation link signal to the handheld Bluetooth system 600, so that the handheld device is handheld. The Bluetooth system 600 establishes a first connection relationship with the vehicle control unit 521 on the carrier, thereby enabling the user to control the vehicle by the handheld device. The first function may be, for example, an action of unlocking the door of the vehicle, unlocking the engine of the vehicle, opening the device inside the vehicle, or other vehicles. For example, when the distance between the carrier and the handheld device is less than the first predetermined distance value, the vehicle control unit 521 can unlock the engine of the carrier, thereby starting the engine or turning on the device in the carrier. In addition, the vehicle control unit 521 may not perform any action by itself until the user controls the vehicle control unit 521 to unlock the engine of the vehicle, start the engine, or turn on the equipment in the vehicle.

In addition, when the user uses the handheld device to command the vehicle control unit 521 to perform an action, the control command may be input, for example, by the input device 604, and the control command may be, for example, an option displayed by the output device 605. Then, the input device 604 transmits the control command to the processor 602. The processor 602 transmits the control command to the processor 512 via the Bluetooth transceiver 601 and the Bluetooth transceiver 511 after learning the control command. Thereafter, the processor 512 transmits the control command to the carrier control unit 521 to control the carrier.

In addition, if the processor 512 of the Bluetooth system 510 determines that the measured distance value is greater than the first preset distance value, the processor 512 can directly pass the vehicle control unit 521 to enable the second function of the vehicle (step 412). First, step 312 is performed, that is, whether the distance value is less than the second preset distance, and then whether to perform step 412. In detail, if the distance value is less than the second preset distance value, the vehicle control unit 521 is passed through to enable the vehicle to turn on the second function (step 412); if the distance value is greater than the second preset distance value, return to the step 210, that is, the distance value, the first preset distance value, and the second preset distance value are obtained again. The second function may be, for example, an anti-theft system for releasing the vehicle, transmitting the vehicle signal to the handheld device, opening the device inside the carrier, or other actions that the vehicle can perform. For example, the processor can establish a connection relationship between the vehicle and the handheld device to enable the vehicle to selectively operate. The action 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 other actions that the vehicle can perform.

In addition, the user can command the vehicle control device 521 to turn on the camera 525 on the carrier, for example, by the handheld device, and transmit the captured image of the camera 525 back to the handheld device. After receiving the image, the processor 602 of the handheld device can transmit the image to the output device 605 of the handheld device, so that the user can instantly view the image captured by the camera device 525 of the carrier.

In addition, if the processor 512 determines that the distance value is greater than the first preset distance value and the carrier is in the state of turning on the first function, the processor 512 may first pass the vehicle control unit 521, for example. The control vehicle closes the first function (step 413), and the processor 512 determines whether the distance value is less than the second preset distance (step 312). Similarly, if the processor 512 determines in step 312 that the distance value is greater than the second preset distance value and the carrier is in the state of turning on the second function, the processor 512 may first transmit the load. After the control unit 521 controls the vehicle to turn off the second function (step 414), the processor 512 additionally obtains a new distance value, a first preset distance value, and a second preset distance value (step 210). The one of the first preset distance value and the second preset distance value or both may maintain the original first preset distance value or the second preset distance value.

Therefore, one of the methods of the Bluetooth carrier control system and the Bluetooth system for managing a close-range vehicle of the present invention is characterized in that the distance between the carrier and the handheld device is determined by using a Bluetooth system.

Another feature of the Bluetooth carrier control system of the present invention and the method for applying the Bluetooth system to manage the short-range vehicle is that the distance between the vehicle and the handheld device is established by the difference in the distance value determined by the Bluetooth system. In order to make the vehicle open to different permissions to the handheld device.

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.
