Description

Telephone System Having Remote Alarm / Interphone Function

The present invention relates to a telephone system having a remote alarm / interphone function, and in particular, a simple structure detects intrusion, fire, gas leakage, etc. of outsiders in the absence of the user, and assumes the user by wire / wireless using a telephone and a telephone line. The present invention relates to a telephone system having a remote alarm / interphone function capable of providing an emergency and a site sound in an interior and making remote calls through an interphone.

Current alarms include sensors for detecting the human body, sensors for detecting shocks, sensors for detecting gases, sensors for detecting changes in pressure, and sensors for detecting temperatures. Voice messages are provided.

As a method of detecting an outsider's intrusion into the house from the outside, it may be known if there is a user at the place where the intrusion occurs, but this may cause damage to human life.

In addition, there is a method through private bodyguards and professional security company, but this also has a problem that the inhabitants living in rural or rural areas do not benefit and the economic burden is increased.

Recently, it has been proposed in Patent No. 228136 to configure a security device using a cordless phone. However, such a device constitutes a security system with a mobile phone stationary body and a sensing sensor, and records from the stationary body when an emergency occurs. When the telephone line is formed by dialing the telephone number, the voice message recorded on the fixed body is unilaterally transmitted, and then each function unit is initialized and the standby state is switched.

Therefore, the security device simply transmits the recorded voice message to the user unilaterally and blocks the call path, so that the user can no longer provide information for judging the situation of the site, so that effective measures according to the situation of the site are prevented. impossible. For example, a more effective response can be achieved if the site situation can be continuously tracked in the event of a fire, gas leak or outside invasion.

In particular, even when his family, etc. return home may be mistaken that an emergency occurred, in this case, the remote user is in a state of anxiety and nervous until checking the situation of the site. Moreover, due to unnecessary operation of the system, unnecessary unauthorized intrusion reports are made to the police station, and thus there is a problem that the police are dispatched to the scene.

Furthermore, since the security device basically includes a radiotelephone as a base in the fixed body and the mobile body, the manufacturing cost is high, and the circuit structure has a complicated problem.

Many conventionally proposed alarm systems have a method of constructing a separate and connected device and using a telephone to automatically notify remote users or government offices after detecting intrusion and detecting fire. This demands a large economic burden on the user.

Moreover, a conventional business telephone or intercom is simply a remote office where the user is frequently away or a place operated by one or a few. Because the call did not have the ability to make the call available, the user could not know the important customer visit quickly.

Therefore, the present invention was devised in view of the problems of the prior art, and its purpose is to have a function as a normal telephone in general, and to detect the intrusion of outsiders, fire, gas leakage, etc. The present invention provides a telephone system having a remote alarm function for informing a user of an emergency situation in a home using a telephone line.

Another object of the present invention is to provide a telephone system having a remote alarm function to enable the user to respond appropriately by transmitting the scene sound of the place where the emergency situation occurred in the home to the remote user.

Another object of the present invention is to provide a telephone system having a function as a normal telephone and having a remote interphone function which enables remote call through an interphone in the absence of a user.

Another object of the present invention is to provide a telephone system with a remote alarm / interphone function that is easy to use and has a simple structure, while minimizing additional cost burden while providing multi functions such as telephone, crime prevention and interphone in home and small business. There is.

And a keypad 13 including a redial button 13a and an on hook key (or speakerphone button) 13b. In addition, the keypad 13 of the present invention further includes a plurality of extended function keys 13c-13h necessary to use the special functions of the present invention.

The extended function keys 13c-13h include a remote control setting key 13c used for setting a remote control number and an extended remote control, a sensor setting key 13d for setting a sensor number and an extended remote control, and an alarm telephone number set. Alarm setting key 13e, interphone operation key 13f used for interphone operation and release setting, alarm operation key 13g used for alarm operation and release setting, password, memory phone number, alarm phone number, And an input key 13h used for input of voice recording and the like.

In addition, the handset 12 is located on the other side of the housing 11, and an indicator 14 for displaying the state and input information of the telephone system is disposed at the top. In addition, on one side of the housing 11, when the theft situation occurs in the alarm setting, when listening to the internal situation from the outside, an interception microphone 15 for receiving a user voice for recording the scene sound and guidance message is disposed.

Meanwhile, the main system 10 is connected to the PSTN exchanger 50 and the mobile communication exchanger 50a through the trunk line 53 from the trunk line connecting terminal formed at one side of the housing 11, and the exchangers 50 and 50a. It is connected to the user's work phone 51 or the mobile communication terminal 52 through.

In addition, each of the sensor systems 20a and 20n has a built-in microcontroller, including an EPROM that stores a system control program and a RAM for temporarily storing data being processed, as shown in FIG. 2. A processor (CPU2) 21 is provided, and the CPU2 (21) is provided with a human body sensor (22) for detecting an intrusion of an outsider (3) installed at an entrance and the like on the input side, and the weak sensing detected therefrom. A comparator 23 for generating the intrusion detection signal by comparing the signal with the reference value REF is connected to the interrupt terminal. The human body sensor may be configured as, for example, an infrared sensor that detects and reacts to weak infrared rays generated from the human body.

In addition, the power supply monitoring circuit 24 for detecting the battery level to determine the time to replace the battery by monitoring the voltage of the built-in battery and the temperature sensor 25 for detecting the temperature of the installation area to determine the fire occurrence are respectively CPU2 ( It is connected to CPU2 21 via the A / D converter built in 21).

On the work side of 21, a radio transmitter 27 for modulating / amplifying the sensor signal sensed by the sensor for wireless transmission through the antenna 28 to the main system 10 is connected.

The microprocessor (CPU2) 21 used for the control of the sensor system of the present invention is, for example, PIC16C711, and SD662 is used as the human body sensor 22. The power monitoring circuit 24 for detecting the battery replacement time detects the battery replacement time by detecting the voltage level according to the change of the power supply voltage using the AD converter inside the CPU2 21 using two resistors. In addition, as a temperature detection method for determining the fire occurrence, the change of the resistance value according to the temperature change using the resistance and thermistor was measured as the voltage change between the both ends of the thermistor, and the detection was performed using the AD converter inside the CPU2.

When the temperature is 35 degrees, the resistance value at the both ends of the thermistor is 28KΩ, and the voltage at this time is 2.05V, which is applied to the input port. At this time, the received information is recorded through the arithmetic processing inside the CPU2 (21). In this case, the CPU2 21 has a resistance value of 24 KΩ and a detection voltage of 1.79 V at 40 degrees, and a resistance value of 20 KΩ and a detection voltage of 1.55 V at 44 degrees. When a corresponding voltage is detected, it is determined that a fire has occurred and an alarm signal is sent to the main system 10.

As described above, since the sensor system 20a and 20n independently configure the driving power of the system by using the battery, the battery system should be operated as precisely as possible without being restricted in the place of installation and in case of emergency such as power failure or power line interruption. In addition to adopting a system operation method that can save energy, it is necessary to inform the user precisely when to replace the battery and to induce replacement in advance.

The operation of the telephone system having the remote alert / interphone function according to the present invention configured as described above will be described in detail below.

(General phone function)

First, the general telephone function is similar to the conventional dialing function using the numeric keys (0-9) of the keypad 13, the speed dial function using the speed dial buttons M1-M4, and the redial button 13a. A redial function and a speakerphone function using an on hook key (or speakerphone button) 13b are included. Operations on well-known functions will be omitted.

(Alarm operation function)

Alarm operation according to the present invention will be described with reference to FIG.

First, as described above, in the setting operation for the system, when the guide message recording, alarm phone number storage, remote control, human body sensor and gas sensor set the door to go out, and set the alarm to the operating state The system goes to standby.

Then, when the outsider 3 intrudes into the room through an alarm, that is, a door or a window in which the human body sensor is installed, the human body sensor 22 operates in the sensor systems 20a and 20n as shown in FIG. The generated infrared rays are detected and the weak detection signal is applied to the comparator 23, and the comparator inputs the detection signal to the CPU2 21 when the input signal is larger than the reference value. Accordingly, when the CPU2 21 includes the intrusion warning data code in the 48-bit transmission data format as shown in FIG. 8, the wireless transmitter 27 modulates / amplifies it and the main system 10 through the antenna 28. Send an intrusion detection signal to In a similar manner, as shown in FIG. 3, the occurrence of fire due to temperature detection and battery replacement according to the battery level are determined to generate a fire detection and battery replacement signal and wirelessly transmit the signal.

Accordingly, the wireless receiver 62 of the main system 10 receives and demodulates a wireless sensing signal and applies 48-bit control data of the sensor systems 20a and 20n to the CPU1 61 (S20). CPU1 interprets the ID and function confirmation code of the sensor system included in the control data and stores this information when it is judged to be unauthorized intrusion (S21), and generates the first control signal through the output port. At 66, at the same time, a warning sound is generated and the system switches to the intrusion occurrence mode and reads the first alarm phone number stored in the input data storage unit 65, for example, the mobile communication terminal phone number (S23).

The CPU1 61 converts the read user's mobile communication terminal telephone number into the DTMF signal in the built-in DTMF generating unit, and is transmitted from the DTMF port of the CPU1 to the PSTN exchanger 50 through the telephone call unit 67. 50 transmits a call signal to the user's telephone 52 through the mobile communication switch 50a (S25).

When the user receives the phone according to the user's call, the audio detection unit 70 of the main system converts the user's voice signal into a square wave through the two stage operational amplifier and recognizes that the user has received the call. (S27), the operation of the siren generator 66 is stopped and when the square wave signal disappears, the CPU1 generates a second control signal to notify the voice data recorded in the voice data storage unit 64, that is, the intrusion alarm situation. The guide message to be sent to the user phone 52 through the exchange 50 (S28).

After the user listens to the intrusion alert guidance message from the outside (S29), the user takes appropriate measures (S30). For example, if the user wants to listen to the situation on the site, enter a specific number (eg, a password). This specific number input signal is input to the DTMF receiver 68 of the main system 10 via the switch 50a, 50 to generate 4-bit output data.

This output data is input to the CPU1 61, and the CPU1 reads this signal and generates a third control signal when the input password matches the password of the system to amplify the field sound received through the tapping microphone 15. Then it is applied to the telephone call unit 67 so that the on-site sound signal is transmitted to the user through the trunk line 53.

Accordingly, when the user hears the scene sound and determines that the person who enters the building is not a malicious outsider 3 but a family member or an acquaintance, the user inputs a preset series of numbers for releasing the alarm operation. Accordingly, the main system 10 sets the alarm to the released state. The on-site sound interception function can prevent or reduce unnecessary unauthorized intrusion due to unnecessary operation of the system even when the family enters and exits in the past.

However, when it is determined that the scene sound confirmed through the interrogation microphone 15 is an outsider 3 of malice, the user calls a crime-related government office such as 112 to report an outsider's unauthorized intrusion and take action.

In addition, when there is no response even when the user transmits a predetermined number of beeps when calling the first alarm phone number, that is, the mobile phone number in step S25, the CPU1 61 of the main system enters the input data. The second alarm phone number stored in the storage unit 65 calls the user in the same manner as above.

On the other hand, when judging at step S21 and not receiving an outsider's unauthorized intrusion and receiving a fire warning data code, the CPU1 61 recognizes that a fire has occurred and switches to the fire generation mode (S31, S32). As shown in the first alarm phone number stored in the input data storage unit 65, that is, the user's mobile communication terminal telephone number is read (S23), the user's telephone number is called.

At this time, when the user answers the call, the audio detection unit 70 converts the user's voice signal into a square wave through the two-stage operational amplifier and inputs the input signal of the CPU1 to recognize that the user has answered the call (S27). When disappearing, the CPU 1 generates a control signal and sends a voice signal recorded in the voice data storage unit 64, that is, a guidance message for notifying a fire alarm situation to the user telephone 52 through the exchange 50 or simply. By transmitting the preset DTMF tones to allow the user to recognize the fire (S28).

After the user listens to the fire alarm guidance message or DTMF beeps from the outside (S29), the alarm is released and take appropriate measures such as a fire report (S30). In addition, CPU1 executes control of the corresponding part under the control of the user.

On the other hand, when judging at step S21, when the battery replacement signal of 48 bits is received, the CPU1 reads this signal and displays the 'battery replacement' on the indicator 14 to induce the user to replace the battery.

On the other hand, when the gas detection signal 30 generates a gas leak signal indicating the gas leak detection and the gas leak signal is input to the CPU 61 of the main system 10 through the external input / output unit 63, the CPU1 In response (S35), similarly to the fire generation mode described above, the process proceeds from step 24 to step S30, informing the user of the gas leak, and allowing the user to report to 119 or the like and return to the home.

The gas detection sensor 30 may be included in the sensor systems 20a and 20n as well as wirelessly connected to the main system 10 through the external input / output unit 63.

(Interphone function)

The main system 10 is connected to the intercom system 40 through the external input / output unit 63 to perform a local / remote interphone function as shown in FIG. 5.

First, when the visitor 2 visits and operates the caller 44, this operation is detected by the main system 10 through the main body connecting portion 41b, and the main system applies power to the interphone system 40. (S40, S41).

Thereafter, the CPU1 of the main system determines whether the user sets the mode of the intercom system 40 to a local interphone or a remote interphone (S42). As a result of the determination, if the mode of the intercom system 40 is set to the local interphone mode (that is, the user is indoors), the chime is operated to notify the user of the room 2 of the visitor 2.

However, if the remote interphone mode is set (when the user is absent), as shown in step S24 of FIG. 7, the user dials the first telephone number stored in the input data storage unit 65 to transmit a ring tone ( S44, S45, S46).

Accordingly, when the user answers the call, the CPU1 of the main system 10 checks the input square wave signal when the received bell signal is converted into a square wave signal by the audio detection unit 70 composed of two operational amplifiers. At the time when the square wave signal disappears, a control signal is generated in the telephone call unit 67 to form a communication path so that the remote interphone is made for a predetermined time between the visitor and the user (S47).

Thereafter, when a predetermined time elapses, the call is terminated by removing power to the interphone system 40 (S48).

On the other hand, if there is no response from the user in step 46, as described above, try to call another stored phone number sequentially or determine whether the ring signal has elapsed 10 times (S49), 10 times When it arrives, the first telephone number is called up to two times (S50), and if there is no response even if it is recalled twice, the interphone power is removed and returned to the standby state (S51).

Therefore, using the above-described remote intercom function of the present invention, if the user is frequently away from the room or a place operated by one person or a few people, the remote site can be easily accessed according to the visitor's intercom call when all the users of the office are absent. It is possible to connect the user to the call so that the user can consult with the customer without missing an important customer's visit.

In the above embodiment, only the human body sensor is used to detect an intrusion of an outsider, but it is also possible to include a door opening / closing sensor in the sensor system installed at the door to detect the opening of the door.

As described above, in the present invention, a simple structure can detect intrusion of outsiders, fire occurrence, gas leakage, etc. in the absence of the user, and can provide emergency situations and field sounds to the user by wire / wireless using a telephone and a telephone line. In addition, remote calls can be made through the interphone, so that appropriate actions of the user and consultation with customers can be made.

In the above, the present invention has been illustrated and described by way of specific preferred embodiments, but the present invention is not limited to the above-described embodiments and the general knowledge in the art to which the present invention belongs without departing from the spirit of the present invention. Various changes and modifications can be made by those who have
