PHONE FOR UNMANNED GUARD AND METHOD OF PREVENTING CRIMES USING THE SAME
TECHNICAL FIELD
This invention relates to an unmanned guard system using a cellular phone, and more particularly to a portable phone for an unmanned guard system and a method of preventing crimes using the same for conducting unmanned watch in real time in a protection space such as an apartment and an office, etc., using the portable phone, automatically warning when an intrusion is occurred, and preventing an illegal intrusion from the outside by setting watch function by remote control irrespective of restriction of distance.
BACKGROUND ART
These days, as crime on various burglaries and larceny gradually increases and becomes society problems, an unmanned guard system has been installed in an entrance/exit of building or any specific space such as bank, government and public office, etc., including home, office, and car, in order to prevent an illegal intrusion of outsider into those objects. In general, this unmanned guard system controls incoming and outgoing people by identifying them by means of prerecorded ID card, password, or fingerprint input, or prevents an illegal intrusion in advance by confirming outsiders' incoming and outgoing using an equipment such as unmanned guard lobby phone, common entrance lobby phone, interphone, etc. In the prior unmanned guard system, however, some disadvantages are that ID card necessary upon entrance/exit may be loss and password may be exposed or known by an illegal intruder or other people, thus making illegal intrusion frequently occurred. Further, notwithstanding that the equipment such as an unmanned guard lobby phone, a common entrance lobby phone, an interphone, etc., is installed, the interphone, etc. does not make response while one is out. This causes the outsider to know the status that a building is empty, thus providing the cause of burglary. Furthermore, the prior system notifies the user or neighboring people of an illegal intrusion fact by sending a warning tone upon an issuance of the illegal
intrusion, but it has a shortcoming in that one can illegally intrude by temporarily holding or stopping an operation of an alarm device.

BEST MODES FOR CARRYING OUT THE INVENTION
Hereinafter, preferred embodiments of the present invention will be explained in detail with reference to the accompanying drawings. Fig. 1 is a diagram for showing a configuration of a portable phone for an unmanned guard system according to the invention, Fig. 2 is a diagram for showing
an example for applying a portable phone according to the invention, and Fig. 3 is a block diagram for showing an internal configuration of a portable phone according to the invention. Referring to Fig. 1, a portable phone 100 according to the invention is installed in a protection space, which requires safety and security, such as apartment and house, office, vehicle, bank or government and public offices, etc. The portable phone 100 is constituted to watch intrusion from the outside by connecting input ports E 1 , E2 and E3 thereof to unmanned guard devices which conducts unmanned guard, and to remotely control by connecting output ports PI to P6 thereof to alarm devices which prevent intrusion from the outside upon outside intrusion. That is, the input ports El, E2 and E3 are connected to an interphone, a power failure sensor and a contact sensor, respectively, which are installed within the protection space, to conduct unmanned watch of the protection space by means of infrared rays received from an infrared ray receiver 110. The output ports PI to P6 are connected to a siren, an automobile starting controller, an emergency light, a camera, a radio and a speaker, respectively, to control the ON/OFF operation of the respective alarm device by means of wireless communications. The portable phone 100 includes not only functions for conducting voice communication and data transmission but also functions for multimedia and electronic note, and communication function for communicating with mobile radio communication network. Thus, the portable phone 100 is usually used as a cellular phone, while it is used as an unmanned guard device upon going out or watch setting for the protection space. That is, the portable phone 100 is multi-functional remote control device which is capable of using by converting the cellular phone mode into the unmanned guard device mode, and vice versa. Further, the inventive portable phone 100 provides convenience to a user by allowing the user to use a remote controller 200 which remotely controls the operation of the portable phone by means of infrared rays. The operation of the portable phόrie 100 of the invention will be explained in detail with reference to Fig. 2. It is assumed that an interphone 11 and a camera 16 for controlling the entrance/exit of a visitor are installed in a gateway of the protection space 1, and the unmanned guard devices such as a power failure sensor 12, a contact sensor 13, a siren 14, an emergency light 15, a radio 17, etc. are installed within the protection space 1. Herein, the power failure sensor 12 is a sensor for watching electric power
failure by heat or humidity, and the contact sensor 13 is a sensor that is mounted to the gateway within the protection space 1 or high priced articles and senses intrusion of the outsider depending on whether or not it is contacted. The siren 14, the emergency light 15, the camera 16, and the radio 17 are devices which are operated to prevent outside intrusion, wherein each of them includes a receiver for receiving control signal provided from the portable phone 100. It should be noted that these unmanned guard devices are merely one embodiment, and thus, if they are device for preventing intrusion of the outsider and safely keeping the protection space 1 , they may be implemented as various modifications. Under such an assumption, the interphone 11, the power failure sensor 12 and the contact sensor 13 are connected to the input ports El, E2 and E3 in turn, respectively, and the siren 14, the emergency light 15, the camera 16, and the radio 17 are connected to the output ports PI, P3, P4, and P5 of the portable phone 100 in turn, respectively. The output port P2 of the portable phone is connected to the automobile starting controller 60 in Fig. 6 to be described after to conduct ON/OFF of the starting of the automobile, while the output port P6 is connected to the speaker 44 in Fig. 3 within the portable phone 100 to conduct a voice output. That is, the input port El of the portable phone 100 receives a buzzer control signal CONT of the interphone 11 and infrared rays signal which corresponds to a speaker voice signal SPK, and transmits the mike voice signal MIC inputted from the mike of the portable phone 100 to speak by interphone with an outside visitor. The input port E2 monitors the power failure sensor 12 for watching whether or not power failure is occurred, receives infrared rays signal if the power failure is occurred, and warns the power failure occurrence fact to the user. The input port E3 monitors the contact sensor 13 for sensing whether or not contact is occurred, receives infrared rays if the contact is sensed, and recognizes that intrusion from the outside is occurred. The output port PI is connected to the siren 14 installed in the protection space 1 , transmits control signal which is set by the user to the siren 14, and remotely controls the ON/OFF operation of the siren 14. The output port P3 is connected to the emergency light 15 within the protection space 1 , and remotely controls the ON/OFF operation of the emergency light 15 by means of wireless communications. The output port P4 is connected to the camera 16 which takes a picture of a
visitor or an intruder from the outside, and controls the ON/OFF operation of the camera 16 to watch illegal intrusion. The output port P5 is connected to the radio 17 within the protection space 1, and controls the ON/OFF operation of the radio 17, thus having the radio 17 turned on as if a person is located in the protection space 1 upon a visit or an intrusion of an outsider. The output port P6 is connected to the speaker 144 in Fig. 3 within the portable phone 100, and warns by outputting the relevant voice signal upon power failure and illegal intrusion. Thus, the inventive portable phone 100 for the unmanned guard system is constituted to watch whether or not the intrusion of the outsider is occurred from the contact sensor 13 through infrared rays, to watch the power failure of the protection space 1 by means of the power failure sensor 12, and to prevent intrusion of the outsider by confirming the visitor by means of the portable phone 100 if receiving the buzzer signal and the speaker signal from the interphone 11. Further, it is constituted to remotely control the siren 14, the emergency light 15, the camera 16, and the radio 17 by means of the portable phone 100 upon going out and emergency so as to prevent in advance intrusion from the outside. Furthermore, as shown in Fig. 2, it is constituted to connected through a base station 300 to a mobile radio communication network 400, and to automatically dial to the preset portable phone 500, and thus to allow the user to confirm intrusion from the outside even a remote distance. For this, the internal constitution of the inventive portable phone 100 will be explained with reference to Fig. 3. The portable phone 100, as shown in Fig. 3, is composed of an infrared rays receiver 110 for transmitting and receiving infrared rays, an input port part 120 having El, E2, and E3, an output port part 130 having PI to P6, a base band processor 140, a mike 142, a speaker 144, a mobile communications chip 150, an LCD 160, a microprocessor 170, and TTS 180. Herein, the input port part 120, as described above, receives infrared rays input signals through the respective port El, E2, and E3 from the interphone 1 1, the power failure sensor 12, and the contact sensor 13, and then transmits the input signals to the base band processor 140 and the microprocessor 170 to be described later. The output port part 130 outputs the relevant control signal through the respective port PI, P3, P4, and P5 to remotely control the operations of the siren 14, the emergency light 15, the camera 16, and the radio 17 within the protection space 1.
The base band processor 140 converts various voice signals into codes (transmission codes) that are harmonized with characteristics of a transmission path by controlling those signals, wherein it is connected to the mike 142 and the speaker 144, and functions to adjust an input/output of the voice signals accordingly. This base band processor 140 is connected to El of the input port part 120, and then receives the mike signal MIC and the speaker signal SPK, and thus allows the user to speak by interphone to the visitor from the outside. The mobile communications chip 150 is a chip that is provided with basic cellular phone functions for voice and data transmission, multimedia and electronic note functions, transmission function for transmitting the control signals produced from the above output port part 130 to the siren 14, the emergency light 15, the camera 16, and the radio 17, respectively, and communications functions for communicating with the mobile radio communication network 400 by a CDMA or GSM method. This chip 150 may be connected directly to the mobile radio communication network 400 through the base station 300. The LCD 160 is a display window that displays generally current time, speaking time, and speaking list when using for the cellular phone and displays watch setting state or alarm message when using for the unmanned guard device. The TTS (Text-to-Speech) 260, which is a type of voice synthesis programs that convert contents of the computer document into voice messages, reads message displayed on LCD 160 upon outside intrusion, and generates voice signal (for example, "Illegal intrusion is occurred") The microprocessor 170 controls whole operations of the system, for example, voice and data transmission functions of the cellular phone. Further, it conducts decoding of infrared rays signal inputted from the input port part 120, transmits the relevant resulted signal to the LCD 160 if outside intrusion or power failure is occurred, and displays it on the LCD 160. Simultaneously, it generates the relevant voice signal by TTS program 180, and then outputs it to the output port P6. Further, it transmits a watch control signals, which are set by a key pad (not shown) or the remote controller 200, to the relevant ports PI, P3, P4, and P5 of the output port part 130 through wireless communications to conduct remote control, respectively. Further, it selectively stores the automatic dialing phone numbers of the portable phone 100 in the memory which is equipped therein, and controls the memory to make an automatic dialing using the previously stored phone number upon outside intrusion.
The remote control through the multi functional portable phone 100 of the invention, the operation of the portable phone 100, and the method for preventing intrusion from the outside will be described in detail based on the above constitution hereinafter. For reference, Fig. 4 is a general flow chart for showing the operation that remotely controls by means of a portable phone of the invention, Fig.5 is a flow chart for showing the method for preventing intrusion from the outside using a portable phone of the invention, and Fig. 6 is a flow chart for showing in detail the operation shown in Fig. 5. As shown in Fig. 4, in case of remotely controlling the watch function through the portable phone 100 of the invention, first of all, the watch function of the portable phone 100 is set using the key pad of the portable phone 100, and then it is determined whether or not the infrared rays is received from the remote controller 200. (S 1 , S2) As a determined result, if the infrared rays is received, it is determined whether the operation of the watch is ON or OFF by decoding the infrared rays signal received from the microprocessor 170. (S3, S4) At this time, as described above, the operations for determining whether or not the infrared rays is received and decoding the infrared rays signal are for the steps according to the remote controller 200 that uses the infrared rays. Meanwhile, when remotely controlling using the portable phone 100 itself, the received control signal may be directly used without experiencing the above operations. If the received control signal is a signal for making the watch function ON, the signal is transmitted to the respective relevant port PI to P5 of the output port part 130, and the siren, the automobile starting, the emergency light, the camera, and the radio are set in ON state, and then it is ended. On the contrary, if the signal is a signal for making the watch function OFF, the signal is transmitted to the respective relevant port PI to P5 of the output port part 130, and the siren, the automobile starting, the emergency light, the camera, and the radio are selectively set in OFF state, and then it is ended. (S6 to S10) According to this remote control, in case of going out or in case that the interphone 1 1, the power failure sensor 12, and the contact sensor 13 are abnormal, they are immediately controlled through the wireless communications in a remote distance, and thus the intrusion from the outside is prevented. The intrusion from the outside may be prevented in advance according to the operations shown in Figs. 5 and 6.
Referring to Fig. 5, first of all, it is determined whether or not the watch function of the portable phone 100 is set. If the watch function is not set, it is set to ON state, and then the power failure sensor 12, the contact sensor 13, and the interphone 11 are monitored in real time using the portable phone 100 as described later. (S50. S51) As a result of monitoring, if the power failure sensor 12 is in ON state, alarm processing that warns the occurrence of the power failure together with the alarm sound is conducted. (S52, S532) If the contact sensor is in ON state, alarm processing that warns the occurrence of the outside intrusion to the gateway of the protection space 1 or the high priced articles is conducted. (S53, S532) According to these alarm processing steps S522 and S532, the siren 14, the emergency light 15, the camera 16 or the radio 17, as shown in Fig. 6, is selectively controlled in a remote distance to conduct proper alarm processing according to the conditions. Herein, after con finning initial alarm setting state, in case of setting the siren 14 ON, the infrared rays control signal is transmitted through the output port PI of the portable phone 100, and thus the operation of the siren 14 is changed to ON state. On the contrary, if not setting the siren 14 ON, the following preparation step is proceeded. (S523 to S525) Then, if setting the operation of the emergency light 15 ON, the infrared rays control signal is transmitted through the output port P3 of the portable phone 100 to turn on the emergency light 15. On the contrary, if not operating the emergency light 15, the following step is proceeded. (S526, S527) Further, if setting the camera 16 ON, the infrared rays control signal is transmitted to the output port P4 to operate the camera 16, and thus the outsider may be identified by taking a picture of the outsider. (S528, S529) Further, if setting the radio 17 ON, the infrared rays control signal is transmitted to the output port P5, and then the alarm processing for turning on the radio 17 is conducted, and thus the outside intrusion may be prevented by setting as if a person is in the protection space 1 upon a visit or an intrusion of the outsider. (S530, S531) If, as a result of monitoring, a call-bell rings by the interphone 11, the microprocessor 170 of the portable phone 100, which is monitoring the interphone 11, detects a visit, and then transmits an alarm sound such as "Please wait a minute" to the interphone 11 through the TTS program 180. Then, the connection with the outside visitor A is conducted, and thus speaking by interphone is possible by means of the portable phone 100. If an automatic dialing phone number is set in the portable phone, the alarm
sound such as "Please wait a minute" is transmitted to the interphone 11, and then the automatic dialing phone number which is set is searched. Then, after connecting to the base station 300 of the portable phone 100, automatic dialing is conducted to the searched phone number. (S543, S544) Then, as shown in Fig. 2, a remote speaking by interphone to the visitor A may be conducted using the portable phone 500 which is in a remote distance. (S545, 546) Accordingly, the power failure sensor 12 and the contact sensor 13 of the protection space 1 are monitored by the inventive portable phone 100, and thus intrusion from the outside or burglary of high priced articles at night due to electric power failure may be prevented, and further outside intrusion may be prevented by providing function for speaking by interphone to the visitor. Fig. 7 is a diagram for showing an example for applying a portable phone according to the invention to an automobile, and Fig. 8 is a flow chart for showing an operation for remotely controlling an automobile using a portable phone shown in Fig. 7. The above described portable phone 100 is explained as one embodiment for conducting function for preventing outside intrusion by connecting the portable phone 100 to the unmanned guard device installed in the predetermined protection space 1. However, the invention is not limited to this embodiment. With reference to Figs. 7 and 8, another embodiment of the portable phone 100 for conducting ON/OFF operation of an automobile starting by remote control by connecting to an automobile starting controller 60 will be explained hereinafter. This portable phone 100 may monitor a contact sensor (not shown) mounted to high priced articles within the automobile to watch whether or not outside intrusion is occurred. Further, as described above, it transmits the relevant signal through output port P2 thereof to the automobile starting controller 60 by means of wireless communications according to a user's setting, and thus making the starting of the automobile ON/OFF. At this time, in case of controlling the starting of the automobile by remotely controlling the operation of the portable phone by means of infrared ray using the remote controller 200, as shown in Fig. 8, first of all, it is determined whether or not infrared rays signal is received from the remote controller 200. (S600) As a result, if the infrared rays signal is received, the relevant signal is decoded, and then a signal for controlling the automobile starting is discriminated. Herein, if the discriminated signal is a signal for setting the automobile starting ON,
it is transmitted through the output port P2 of the portable phone to the automobile starting controller 60 to make the automobile starting ON.(S610 to S640) Thus, the inventive portable phone 100 has an advantage in that the portable phone 100 may be used in stead of the remote controller of the automobile when a locking key of the automobile is lost or locking is conducted leaving the locking key in the automobile. As described above, the portable phone for the unmanned guard system according to the invention is not limited to the above embodiments, and it is apparent that many changes and modifications may be made without departing from the scope of the invention as defined in the appended claims by those skilled in the art.
