Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a bag capable of charging electronic equipment,

The present invention relates to a bag equipped with a solar charging system, and more particularly, to a bag having a solar charging system so that efficient charging can be performed, and a Bluetooth module and a GPS module can be mounted, The present invention also relates to a bag equipped with a solar charging system in a bag equipped with a solar charging system capable of actively detecting the position of the bag.

In general, modern people carry a variety of handbags such as purses, mobile phones, keys, bags, computers, and the number of handbags increases as industrialization progresses.

However, when the lost or invisible handset is lost, it takes a long time to find it, and in the case of a lost handset, the loss due to the loss of various identification cards and important documents is large.

For example, if you lose your bag, you will need to reissue the documents, ID, or credit card stored in your bag, and in some cases, for illegal purposes.

To solve these problems, various techniques for informing the loss of the bag have been proposed.

For example, by mounting a signal generating device in a bag and mounting an application in a mobile communication device such as a smart phone, the position can be grasped when a bag is lost.

However, since such a conventional position detecting apparatus can not keep communication with the smartphone when the charged amount of the battery mounted in the bag is exhausted, it is difficult to grasp the position of the bag when a long time has elapsed after the loss .

In addition, since the sensor attached to the bag operates only when the user activates the application and tracks the position, the position signal is transmitted. Therefore, when the bag is lost, it is difficult for the user to immediately recognize the position.

Patent Application No. 10-2009-67489 (Name: Device for preventing loss and method thereof)

SUMMARY OF THE INVENTION Accordingly, the present invention has been made in order to solve the above-mentioned problems, and it is an object of the present invention to improve the structure of a power supply part of a bag, thereby minimizing the amount of power consumed and maintaining the communication state even when the bag is lost for a long time, The present invention provides a bag equipped with a solar charging system capable of recovering a solar battery.

Another object of the present invention is to provide a bag equipped with a solar light charging system capable of detecting a lost bag or detecting the bag in real time by having a position sensing device in the bag.

In order to accomplish the above object, an embodiment of the present invention provides a wireless communication system comprising: a Bluetooth module for maintaining a short distance communication state with a communication device;

A GPS module for transmitting and receiving GPS signals and providing position information;

A communication module for transmitting the position information of the bag to the communication device in cooperation with the GPS module;

A controller for determining whether the distance value is out of a predetermined range by calculating a distance value between the bag and the communicator period in cooperation with the Bluetooth module, the GPS module, and the communication module;

An alarm unit for generating an alarm when the distance value is out of a predetermined range by interlocking with the control unit;

A display unit for displaying position information; And

The present invention provides a bag equipped with a solar charging system including a power supply unit for supplying power.

According to the above-described configuration, the bag equipped with the solar charging system of the present invention has the following advantages.

First, by providing a Bluetooth module in the bag, the Bluetooth module maintains a real-time close-up communication state with the user's smartphone. When the Bluetooth module is out of a certain distance, the Bluetooth module detects the alarm and generates an alarm sound.

Second, electricity can be produced by solar charging, and electronic devices such as mobile phones and PCs can be charged using the electricity generated.

Third, since the GPS module and the CDMA module are provided, the position of the bag can be grasped in real time, and the user can quickly grasp the position of the bag by communicating with the smart phone.

Fourth, if the bag is completely lost, the application of the smart phone is activated to transmit a signal, and the communication module of the bag position sensing device and the GPS module are interlocked to transmit the position of the bag to the smart phone, .

Fifth, by additionally attaching a wake-up unit to the bag position sensing device, it is possible to efficiently prepare for communication with a user by minimizing power consumption when long-time communication with a smartphone is difficult, such as a loss.

Sixth, when the acceleration sensor is interlocked with the wake-up part, when the wobble of the bag is detected and there is no wobble, it is judged that the wake-up part is in a state of neglect due to loss and the wake-up part is turned on to minimize power consumption, I can prepare.

FIG. 6 is a schematic view illustrating an acceleration sensor according to another embodiment of the control unit shown in FIG. 3. Referring to FIG.

Hereinafter, a bag provided with a solar charging system according to the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIGS. 1 to 4, the bag 1 equipped with the solar charging system proposed by the present invention is provided with a position sensing device 5 so that its position can be grasped in real time, And a power supply unit 10 for charging external electronic devices such as a mobile phone and a PC by means of the charged electricity.

In this bag 1, the position sensing device 5 of the bag 1 includes a Bluetooth module (Blue tooth module) 14 for maintaining a short distance communication state with the communication device 3; A GPS module (GPS module) 16 for transmitting and receiving GPS signals and providing position information;

A communication module (18) for transmitting the position information of the bag (1) to the communication device (3) in cooperation with the GPS module (16);

A control unit for determining whether the distance value is out of a predetermined range by calculating a distance value between the bag 1 and the communication device 3 in cooperation with the Bluetooth module 14, the GPS module 16, (30);

An alarm unit 20 interlocked with the control unit 30 to generate an alarm when the distance value is out of a predetermined range;

A display unit (22) for displaying positional information; And a power supply unit 10 for supplying power to the solar cell panel.

In the bag position sensing device 5 having such a structure, the Bluetooth module 14 uses the 2.45 GHz frequency with the communication device 3 located at a short distance, for example, the mobile communication device 3 such as a smart phone And performs wireless communication.

The Bluetooth module 14 includes a Bluetooth chip, a balun circuit, a band pass filter, and a frequency oscillator. The Bluetooth chip preferably employs the CC2510 model, or BC05-EXT. Of course, the present invention is not limited to this, and various chips are applicable.

The balun circuit is used as a transformer to match the impedance between the IC and the antenna. The balun circuit consists of a balun and several L, C elements.

The band filter filters the signal transmitted through the balun circuit to pass through the Bluetooth band (2.402 GHz to 2.480 GHz).

Various types of oscillators are applicable to the frequency oscillator, but preferably a crystal oscillator (X-Tal) is used.

These frequency generators set the number of clocks to a certain frequency band, preferably 26 MHz.

Accordingly, the Bluetooth module 14 having the above-described structure can easily transmit and receive a signal to the nearby communication device 3, for example, a smart phone, by using the near field communication.

The control unit 30 calculates the distance to the communication device 3 by interlocking with the Bluetooth module 14 and transmits a signal to the alarm unit 20 according to the calculation result to generate a warning sound.

More specifically, as shown in FIG. 4, the control unit 30 includes an input unit 27 for receiving signals from the Bluetooth module 14, the GPS module 16, and the communication module 18; An arithmetic unit 32 for determining whether the bag 1 and the communication device 3 are out of a predetermined distance by calculating an input signal; And an output unit 34 for transmitting the calculated result value to the alarm unit 20 to generate an alarm sound.

In this control unit 30, the operation unit 32 numerically processes the signal input from the Bluetooth module 14 to obtain the distance value. Then, the distance value is compared with the alarm distance value, thereby calculating whether or not the bag position sensing device 5 is out of the reference distance with the communication device 3. [

In this case, the alarm distance value means a distance at which the alarm unit 20 generates an alarm when the distance between the bag position sensing device 5 and the communication device 3 exceeds a certain distance. These alarm distance values are preset in the memory.

Therefore, the operation unit 32 compares the distance value input from the Bluetooth module 14 with the alarm distance value extracted from the memory.

As a result of the comparison, when the alarm distance is out of the predetermined range, the alarm unit 20 transmits a signal to the alarm unit 20 through the output unit 34 to cause the alarm unit 20 to generate an alarm sound.

The user recognizes that the bag 1 is separated from the communication device 3 by a predetermined distance or more by the alarm part 20. Generally, since the communication device 3 such as a smart phone is carried by the user, the occurrence of an alarm sound means that the bag 1 has deviated from the user by a predetermined distance or more, which may mean loss.

Therefore, the user can recognize the warning sound and quickly grasp the position of the bag 1 such as a bag and retrieve it.

The alarm unit 20 can generate a warning sound in various ways. For example, it is possible to generate an alarm sound of a predetermined decibel (db) by a signal of the control unit 30 as a normal buzzer method.

Alternatively, as another embodiment of the present invention, in a noisy environment such as a factory, audible information such as an audible alarm is inefficient and thus a visual system is more efficient. Therefore, in this case, a light emission method using an LED element or the like is applicable.

On the other hand, at the same time that the mobile phone position sensing device 5 generates the alarm sound, it transmits the GPS position information to the communication device 3 by the mounted communication module 18. [

More specifically, the GPS module 16 applies a GPS module of a conventional structure. That is, the GPS module has a high frequency section that converts a 1.2 or 1.5 GHz signal received by an antenna into a low frequency signal that is easy to handle and a despreader that restores the spread spectrum to its original state, And a calculator for calculating a message obtained from the signal processor and a current position in a pseudo range.

The GPS module 16 calculates the current position in real time by receiving the GPS signal from the satellite.

The communication module 18 receives the position information from the GPS module 16 and transmits it to the outside through the antenna. By receiving the transmitted location information in the communication device 3 such as a smart phone, the user can grasp the current position of the bag 1 in real time through the application 6 of the smart phone or the like.

The communication module 18 may be a variety of connection methods such as FDMA, TDMA, and CDMA, but preferably includes a communication module 18 of a code division multiple access (CDMA) scheme. In particular, W-CDMA (Wideband CDMA) or CDMA-2000 can be used.

Accordingly, the control unit 30 can transmit the position information calculated by the GPS module 16 to the communication device 3 such as an external smart phone by the communication module 18. [

Thus, by activating the smartphone application 6, the user can grasp the position of the bag 1 in real time by receiving the signal transmitted from the bag position sensing device 5 by the smart phone.

As described above, it is possible to use a manual method in which a smart phone receives an external signal to determine its position, but conversely, the smartphone may actively transmit a signal to detect the position of the bag 1.

That is, the user activates the application 6 of the smartphone and selects the position sensing mode of the bag 1. When the mode is selected, the smartphone transmits a signal, and the transmitted signal is received by the communication module 18 via the antenna of the baggage position sensing device 5. The communication module 18 receives the signal and transmits the signal to the control unit 30, and the control unit 30 grasps the position information inputted from the GPS module 16. Then, the position information is transmitted to the smartphone through the communication module 18 and the antenna.

Therefore, the user can easily grasp the current position of the bag 1 through the smart phone. This function can be very useful not only when the smartphone is temporarily hidden, but also when it is completely lost.

The power supply unit 10 includes a solar cell panel 22 for generating electricity; A plurality of batteries (24, 26) for charging the developed electricity; A receptacle 23 to which an external electronic device can be connected; A control unit 25 for charging the batteries 24 and 26, which draws out the power from the batteries 24 and 26 having a sufficient charge amount when the charge amount is insufficient and detects the charge amounts of the batteries 24 and 26, .

In the power supply unit 10 having such a structure, the solar cell panel 22 may include various types of solar cell panels. That is, it may include a crystal battery panel and a thin film battery panel of a flexible material.

The electricity generated through the solar cell panel 22 can be charged into the plurality of batteries 24 and 26.

The receptacle 23 is connected to the batteries 24 and 26 to supply electricity to the outside. That is, it is possible to drive by connecting a plug of an electronic device requiring an external power source such as an external cellular phone or a PC to the receptacle 23.

The controller unit 25 is provided with a charge capacity determination circuit for the batteries 24 and 26, so that the charge capacity of the batteries 24 and 26 can be grasped. That is, the charging capacity determination circuit of the batteries 24 and 26 is provided with a memory portion in which the internal resistance of the batteries 24 and 26 and the difference voltage V of the batteries 24 and 26 are stored, And a voltage sensing unit for measuring a variation voltage (? Vt) of the batteries (24, 26).

Therefore, the discrimination circuit discriminates the charging capacity of the batteries 24 and 26 by comparing the difference voltage? V stored in the memory with the fluctuation voltage? Vt measured by the voltage sensing unit, and the controller unit 25 Thus, the state of charge of each battery 24, 26 can be grasped.

The control unit 25 electrically connects the batteries 24 and 26 that are insufficiently charged to the solar cell panel 22 to charge the batteries 24 and 26 and connects the buffered batteries 24 and 26 to the bag position sensing device 5 So that power can be supplied.

As described above, by selectively using the plurality of batteries 24 and 26, supply of power can be smoothly performed.

Meanwhile, as another embodiment of the present invention, a wake-up portion 36 is further provided in the bag position sensing device 5, thereby minimizing the use of the power source.

4 and 5, the wakeup unit 36 is activated when an external signal is received in the sleep mode, thereby resuming the power supply.

The wakeup unit 36 includes a clock generator 40 for generating a clock signal, a receiver 42 for receiving an external signal, and a CPU 44 for generating an active signal by the received signal.

Accordingly, when the wakeup unit 36 receives a sensing signal from the outside, the CPU 44 transmits a signal to the control unit 30 to operate the bag position sensing apparatus 5 in a steady state. As a result, the bag position sensing device 5 can be used only for a long time because it can reduce unnecessary power consumption by operating only when necessary.

When the bag 1 is lost, the possibility of being left for a long time is high. In this case, since the amount of charge of the self-contained batteries 24 and 26 is not sufficient, it is necessary to minimize the power consumption, The object can easily be achieved.

Furthermore, when the bag 1 is not moved by interlocking with the acceleration sensor 38, the wakeup unit 36 can more efficiently minimize the power consumption.

6, the acceleration sensor 38 is attached to the bag position sensing device 5 so that the acceleration sensor 38 senses the shake when the bag 1 moves. When the bag 1 is lost and left at a certain place for a long time, the bag 1 does not move, and this case is often lost.

In addition, since it takes a long time for the user to collect the bag 1 again in case of loss, it is necessary to maintain the communication state with the user's smartphone during that time, so consumption of the power source must be minimized.

Accordingly, the acceleration sensor 38 senses whether the bag 1 is moving and transmits a signal to the control unit 30. The control unit 30 calculates the signal to determine whether the bag 1 is in a moving state or in a left state . For example, if the signal value inputted from the acceleration sensor 38 is within a certain range, it is judged that it does not move, and if it is more than a certain range, it is determined that it is in a moving state.

If it is determined that the vehicle is left untreated, the control unit 30 transmits a signal to the wakeup unit 36 to switch to the ON state. Therefore, the wakeup unit 36 minimizes power consumption and is driven only when an external position sensing signal is received.

The control unit 30 transmits a signal to the wakeup unit 36 to switch the bag 1 to the OFF state so that the bag position sensing device 5 always maintains communication with the smartphone .

In addition to the acceleration sensor, a gyro sensor and the like are also applicable.
