Description

The utility model relates to cellular telephone systems. The system is a universal device that combines the functions of a cell phone and a security alarm system and has a housing in the form of a regular stationary telephone.

The principle of communication in a stationary cell phone is the same as in a mobile phone, and the communication quality is better, since the position of the device is fixed and there is an external antenna.

It is known that the fee for connecting subscribers to a conventional wired telephone network is high, especially in rural areas, where telephone lines are not available or have exhausted the possibilities of increasing the number of subscribers. These lines are carried out at the expense of the connected subscribers and the cost of access to wire telephone services is the sum of the cost of the communication line, connection fees, the cost of the device itself and the monthly subscription fee. Whereas the cost of access to telephone services using a stationary cell phone will consist of the cost of the device itself and payment for telephone services in accordance with established tariffs.

Hence the obvious advantage of a stationary cell phone is indispensability in cases where it is not possible to establish a conventional wired one. As a result, the consumer gets the opportunity to telephone the office, cottage, cottage, warehouse, gas station, etc., without waiting for a connection to a wired telephone network.

Potential customers of the device for marketing research will be people of an older age level, patients and people with impaired vision, for whom the use of conventional mobile phones is associated with significant difficulties or is generally impossible due to the small size of buttons and inscriptions, as well as because of the excess multifunctionality of mobile cell phones.

An analogue of the proposed device is the device GDP-02 of the Czech company Jablotron (journal "Science and Life" No. 7, 2005), which works on the principle of a cell phone, but is made in the form of a regular landline phone and contains a large rotary screen, conventional numeric buttons and a full set alphabetical, arranged in the same order as on the keyboard of a typewriter or computer. The disadvantages of this device are the presence of a large number of buttons, which is redundant for older people and the presence of which leads to

the rise in price of the design, as well as this device does not have the function of the panic button, necessary for the elderly and sick people.

The panic button connected to the device is designed to enable people who are at the facility where the proposed device is installed to instantly inform about the alarm situation at the facility. For example, children left alone in the apartment can quickly inform their parents about this if an unauthorized person tries to enter the apartment by pressing a button. Elderly people with limited mobility, at the time of a temporary absence of people looking after them, can press them to inform them about the deterioration of their well-being, which will allow them to take the required actions in time. An alarm button installed in crowded places will allow you to discreetly inform about cases of illegal actions in relation to those present. The cell phone numbers by which the system informs of an alarm situation are pre-programmed into the device’s memory. To activate the transmission of an alarm call, just a single click on the alarm button. Moreover, the device can be programmed in such a way that information about the alarm situation will be transmitted to a specialized point of protection.

The technical result of the utility model is combining the conveniences of using a traditional wired telephone and the advantages of GSM technology in one device, creating an inexpensive wireless telephone communication device combined with the panic button function.

The technical result is achieved in that in a case resembling a regular landline telephone, there are: a GSM module controlled by an internal or external microcontroller, dialer and control buttons, which are large in size, a socket for connecting mains power, a backup power source, a stabilizer voltage with charging circuit, internal antenna, connector for connecting an external antenna, telephone handset, connectors for connecting the panic button and security sensors.

The device has the ability to call emergency services by dialing standard numbers accepted in a wired telephone connection, such as fire department - 01, police - 02, ambulance - 03.

The device has a mode of recording telephone numbers in the memory of the telephone directory of the device and the ability to quickly dial them with the touch of just one button.

Figure 1 shows a block diagram of a device where the following notation is introduced:

1 - GSM module;

2 - microcontroller;

3 - internal antenna;

4 - connector for connecting an external antenna;

5 - a telephone receiver;

6 - buttons of the dialer and control;

7 - power supply unit;

8 - backup power source;

9 - stabilizer with a charging circuit;

10 - power selection key;

11 - panic button;

12 - connector for connecting external devices.

The device has the form of a conventional stationary push-button telephone with a handset 5 connected to the device by means of a twisted cord, operating in duplex mode.

The device operates as follows. The microcontroller 2, which is external to the GSM module 1 or built into it, depending on the input actions on it, submits, according to the algorithm programmed into it, various control commands to the GSM module 1 executing them, which ensures the given algorithm of the device.

GSM module 1 supports the GSM standard, has digital and analog input / output lines and the following interfaces: radio interface, SIM interface, audio interface, serial interface for exchanging data and receiving commands ..

The device has two types of power sources: the main power source is the mains power supply unit 7, operating from an alternating current network of 220 V, and the backup power source 8 is a rechargeable battery, which allows the device to function for a certain point in time when the voltage in the power supply is disconnected.

Depending on the availability of mains power, the key 10 switches the device’s power either from the output of the stabilizer 9 or from the backup power source 8. In the case of a discharged state of the backup source 8 and the presence of mains power, the stabilizer with charging circuit 9 recharges it.

An external antenna connected to connector 4 of the device allows you to establish stable communication in the area of poor signal reception by mobile cell phones.

The device may have an indicator that displays dialed numbers, numbers of callers, SMS text, operating modes and other information.

The device may be able to protect objects, notifying the subscriber about emergency situations at the object that occurred in the room when the owner was absent, by interrogating the status of various security sensors connected to it. The information transmitted in the message contains data on the triggered security sensors. Possible types of sensors used: volumetric; infrared; contact magnetic; smoke gas; shock, etc. Information about an emergency situation is transmitted in the form of sending SMS messages to phones recorded in the device in the notification list (up to 3 numbers). The protection mode is activated and deactivated by means of SMS messages from the user's mobile phone, and contact or contactless cards or keys can be used via an electronic reader. Phone numbers of users who have access to control the device are stored in the device’s memory. Control SMS messages from mobile phones not registered in the memory are ignored. Moreover, the device can be programmed in such a way that information about the penetration of the object will be transmitted to a specialized point of protection.

The panic button 11 connected to the device can use either a wired connection or use a radio channel. In the case of using the radio channel, the panic button looks like a wearable keyfob with an autonomous power source, and a low-power transmitter will be built into the keychain, and a receiver will be installed in the device. In the room, several panic buttons 11 can be installed.

When a subscriber makes a voice call, the user dials his number by pressing the buttons 6. In this case, information about the dialed number from the keyboard goes to GSM module 1, which transmits it to the base station. End the conversation by pressing the handset lever 5 or lowering the handset 5. After the call is received, the connection is made by removing the handset 5 from the device after releasing the handset lever.

The device may have a GPRS modem and the ability to connect external devices to it.
