Description

Mobile Phone Safety System {System for Cellularphone Safety}

The present invention relates to a system for promoting safety of a mobile phone and a user after a power cut. More particularly, the present invention relates to a mobile phone using a short-range low-power communication channel and an auxiliary power supply that exist after the main power of the mobile phone is cut off. The message about the current situation of the telephone is transmitted to a communication module of the same standard within the short range communication range, and the received mobile phone transmits the message to the corresponding base station using its own telecommunication channel, and the corresponding base station It relates to a system for recording records. Here, the recording refers to information on the state of the mobile phone user including information at the time when the power is cut off when the main power is cut off and the position tracking is impossible. Here, the telecommunication channel refers to a commercially available cellular phone communication standard such as CDMA and HSDPA, and the short range communication channel refers to a low power short range communication channel such as Zigbee.

Cell phones are becoming an essential household item. In addition, the technology that tracks the location of emergency patients and their current location in case of loss of mobile phones is being provided, and is limited in the case of pre-subscribing the service in the aspect of personal privacy protection or with the permission of the Fire Department and the National Police Agency. Can be used. However, the power supply of the mobile phone cannot be sufficient in all emergency situations, and an appropriate system is required to cope with the user's safety and the mobile phone crime in case of intentional power off. In particular, the meaning that the power of the mobile phone is usually cut off can be recognized as being out of the general user's situation, and a proper function for the current state after power off is required for a proper response.

Conventionally, it operates a service that tracks the location based on the information of the base station near the mobile phone, a precise positioning technology such as GPS (Global Positioning System), and a service using a fixed communication module indoors such as a building where GPS is not possible. In the meantime, active research is underway, but all services are not available after power off. In addition, although the service is not active at present, the fixed location module for location tracking in the indoor operation is limited, but due to the problem of high installation and management costs, the installation rate is low and can be used only in limited spaces.

In order to solve the above problems, the present invention comprises an auxiliary power source that operates independently of the main power source of the mobile phone, a low power short-range communication channel, and a part for detecting an attempt to arbitrarily damage the components, and then, after the power is cut off, In order to overcome the limitations of the current system that cannot be tracked, the object of the present invention is to provide a system that can independently report the status of a mobile phone regardless of whether or not main power is present.

In addition, the control unit 30 is the MCU 31, it can be characterized in that it can be implemented in all kinds of MCU that can be used as a package of the transmitter and receiver, such as Zigbee and Bluetooth for the recent communication.

In addition, the auxiliary power source 40 is characterized in that it can operate independently from the main power source of the mobile phone, while sharing the electrical energy resources until the main power source is available, or below a certain level of the main power source or suddenly It can be operated independently at the time of removal.

In addition, the system is characterized in that it applies the ad hoc network (Ad hoc network) technology that can transmit and receive messages generated for the same purpose.

In addition, the wireless communication method of the transmitting and receiving unit 50 may be characterized in that the short-range wireless communication method based on the low power design technology, the representative short-range wireless communication method is Zigbee (Zigbee), Bluetooth (Bluetooth), It is a high frequency (RF), UWB system, etc., It can be characterized by any one of these.

The mobile phone security system according to the present invention can remotely track the current location by using an auxiliary power source and a short-range communication channel so as to determine the location of the mobile phone when the main power source of the mobile phone is in an unusable state.

For the sake of user convenience or safety, it is also possible to use a location tracking technology such as a forest fire detection system that is currently being distributed and operated or a RSSI (Received Signal Strength Indication) technology that tracks the current location inside a building with signal sensitivity. Can be.

In addition, the recent illegal attempt to open a pirated cell phone used for crime, the mobile phone may request the rescue or give a notification and leave a record to prevent additional crime, It may be helpful in case investigation. In particular, police and prosecution investigations can be provided by providing clues to estimate the final location of those at risk, such as abductions, kidnappings and suicides.

In addition, since indoor location tracking technology is based on the mesh network technology and the ad hoc network technology, the accuracy of location tracking increases when the amount of mobile phone employing the technology increases. have.

The terms or words used in this specification and claims are not to be construed as limiting in their usual or dictionary meanings, and the inventors may appropriately define the concept of terms in order to best explain their invention in the best way possible. It should be interpreted as meaning and concept corresponding to the technical idea of the present invention based on the principle that the present invention.

Therefore, the embodiments described in this specification and the configurations shown in the drawings are merely the most preferred embodiments of the present invention and do not represent all the technical ideas of the present invention. Therefore, It is to be understood that equivalents and modifications are possible. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a mobile phone security system according to the present invention, Figure 2 is a block diagram showing an embodiment of a mobile phone security system according to the present invention.

As shown in FIG. 1, the mobile phone security system according to the present invention includes a signal detecting unit 10 for detecting whether the power of the mobile phone is turned on or off and an opening detection for detecting the opening of the board of the mobile phone arbitrarily. The unit 20 determines whether the detected signals are caused by a power cut or intentionally opening the cellular phone board, transmitting an emergency signal, receiving a request from another device, and sending a remote communication channel to the base station. And a control unit 30 for transmitting, an auxiliary power source 40 for enabling short-range communication after the main power is cut off, and a transmitting / receiving unit 50 capable of transmitting and receiving short-range wirelessly.

The signal detecting unit 10 measures whether the mobile phone operates with the main power source and the remote communication channel is in a usable state, or whether the main power is not available and the cell phone is turned off. Preferably, the presence or absence of the power supply of the cellular phone can be easily confirmed by connecting the terminal in the substrate indicating the presence or absence of the power supply of the substrate of the cellular phone and the input / output terminal of the microcontrol unit such as the MCU 31. Here, it should be understood that various forms exist for the same function as the signal detection unit 10. In addition, the opening detecting unit 20 detects whether the case of the cellular phone is opened, and functions to detect an artificial act on the cellular phone substrate. In fact, in the case of the opening detecting unit 20, it is true that it is not a novel invention element with excellent novelty. However, until now, the elements that function as the opening detecting unit 20 have been ineffective because they attempt to open after the user's intentional power off. However, the mobile phone security system according to the present invention is highly effective because a separate power supply is made using the auxiliary power supply 40. Typically, the sensing unit based on the principle of the switch 21 is suitable, but not limited to the switch 21.

The signals detected by the signal detector 10 and the tear detector 20 are received and processed by the controller 30. The control unit 30 confirms that the power of the mobile phone is cut off by the signal detecting unit 10 and the unsealing detecting unit 20, and determines whether the current state of the mobile phone board is opened. The control unit 30 attempts to search for another mobile phone within the signal reach distance through the low power short-range transmitter / receiver unit 50 to transmit the current situation of the mobile phone to a nearby mobile phone base station. If the phone is found, it will request signal transmission and if it is not found, it will keep trying. However, due to the power off of the mobile phone, a problem that cannot be seen as a situation of lost or stolen the mobile phone occurs, the control unit 30 determines whether it is a normal situation such as battery replacement or an emergency situation to send a request message. Is also done.

The controller 30 ultimately utilizes a transmitter / receiver to report its situation to the base station, but prepares for another mobile phone to respond to the request in a situation where its status does not require reporting to the base station. To this end, it is desirable to adopt a wireless communication method capable of transmitting and receiving with one communication module. Figure 2 is a case of using a Zigbee (Zigbee) transmission and reception chip as the transmission and reception unit 50, since the wireless communication chip is usually produced on the premise of two-way communication, commercially available short-range wireless communication chip, preferably operates at low power Zigbee (51) chip that is a chip for short-range communication can be used.

When the main power of the cellular phone is turned off, the auxiliary power source 40 controls the current state of the cellular phone as grasped by the signal detecting unit 10 and the opening detecting unit 20. It is the part that supplies power to transmit the signal through 50). In general, Zigbee communication standard is a AA standard battery that can be sent and received for 10 years. Therefore, it is desirable to use a battery of sufficient capacity to be used during the replacement cycle of a mobile phone. However, in consideration of cost and size, the battery may have a structure in which the battery has sufficient capacity and size, but is charged during the period of using the main power and operates independently from the main power after the main power is cut off.

The mobile phone security system according to the present invention can be used for receiving a transmission request using a short-range communication channel of another device of the same system, and can transmit a request message to a mobile phone base station according to whether a remote transmission channel is available. . If the request message cannot be delivered due to the limitation of the signal delivery distance of the transmitter / receiver, the device that attempted the first request continuously attempts to transmit the request message to the local channel. Through this repetition, a device capable of transmitting a telecommunication channel can be seen as a combination of mesh network technology and ad hoc network technology, which is a principle of transmitting over multiple short-range transport channels. FIG. 3 is a simple diagram illustrating a sequence of implementing a technology in which a mesh network technology and an ad hoc network technology are combined.

Records by the mobile phone security system according to the present invention can be left to the base station to be used by the user's needs, and can be managed for use in emergencies or criminal investigations, problems such as privacy infringement that can be expected to occur It can be overcome by management by a limited qualified person and can be used in the current way, with limited use only by the fire authorities and the police when a crime or emergency patient occurs. On the one hand, a record of the request message can be received by a provider other than the one to which the cellular phone is subscribed, but can be managed securely if it is integrated and limited in its use.

Even in the short-range communication channel of the cellular phone security system according to the present invention, a case where the cellular phones are concentrated within the signal reach may occur. This problem can be used to prevent the flooding of messages through congestion control by using the current technology that can adjust the signal delivery distance according to the power strength.

4 is a flowchart illustrating the transmission principle of the mobile telephone security system according to the present invention, and FIG. 5 is a flowchart illustrating the reception principle of the mobile telephone security system according to the present invention. 6 is a diagram showing the principle of the mesh network and ad hoc network technology in the operation of the transmitter and receiver, the absolute distance from the '1' point to the '2' point shown in the figure is a mobile phone security according to the present invention It is a technology that enables communication via routers within a communication range, assuming that short-range communication of the system is impossible. By using a near field communication channel, the message reach is virtually extended. As a result, a device capable of long distance communication can be searched through the near field communication channel.

7 is a view of an expected substrate when the mobile phone security system according to the present invention is applied. Positioning during substrate design can actually produce a much smaller, lighter, and simpler form than the expected size and position of the substrate.

4 is a flowchart when the cellular phone security system according to the present invention attempts to transmit a message. Investigate whether the board is opened after the mobile phone's main power is turned off to determine whether it is a high-level emergency message request or a low-level request message. The lower level corresponds to the case where the interval is long. The level of the request message according to the state is intended to detect intentional external access attempts such as opening the substrate. The controller 30, which grasps the level of the request message, searches for a safety system of another mobile phone within a short distance communication range. When the condition that the transmission can be made is satisfied, the controller 30 transmits the request message and requests to transmit it instead. In this case, the condition refers to whether the main power source of the cellular phone is available, so that the requested message can be delivered to the corresponding base station. If there is no answer mobile phone within the communication distance, the message transmission is repeated to satisfy the transmission condition to the base station in order to utilize the mesh network technology and the ad hoc network technology described in FIG.

The mobile phone security system according to the present invention uses the same apparatus at the time of reception as at the time of transmission, and FIG. 5 shows a flowchart at the time of reception. Receiving is a state in which the cellular phone is turned on, and a commercial cell phone service such as CDMA is available, or even if it is not satisfied, it is ready to receive and process a request message from another device after transmitting a request message. When it receives the request signal, it finds out whether it can transmit it to the base station using its own telecommunication channel and delivers the message if possible, and if it is impossible, it responds that it is impossible in its own remote channel. After the impossible response, the terminal becomes a transmission state in the mesh network from the receiver's state and searches for a device capable of using a telecommunication channel and attempts to deliver the requested message. If such a request signal is not received, it waits until a request signal comes.

The mobile phone security system according to the present invention functions to search for a remote communication possible channel by utilizing a mesh network technology and an ad hoc network technology of a low power based local area communication channel. And when artificially attempting external access to the cell phone board, it is a system that helps to find criminals and emergency patients by sending a rescue request message. In particular, it is essential to use an auxiliary power source and a short-range communication channel for the case where the main power source of the mobile phone cannot be used and thus the utilization of the remote communication channel is impossible. Recently, mobile phones incorporating main power into devices have been released, but the mobile phone security system according to the present invention not only enables a low power communication channel to be used in place of the main power by using an auxiliary power but also artificially The invention includes a function that detects an attempt to open the board and detects the danger of access from the outside, and informs of the danger. It is a system that protects the safety of the mobile phone user and uses the records of request messages to assist in criminal investigations using the mobile phone. have. In a very brief manner, the mobile phone security system according to the present invention can be compared to whether a rescue request such as '119' is made by yourself in an emergency, or someone in close range where my voice reaches.
