Description

The utility model relates to the field of burglar alarm and can be used as a security device designed to record touching or approaching the subject of protection and signaling to this device or to a user's computerized (mobile) device, for example, a smartphone, tablet and other.

Currently, there is the problem of preventing the loss of various objects (due, for example, to forgetfulness of the owner or theft). The owner usually wants to be constantly informed about whether the controlled object is in the vicinity of it and if it is missing for any reason. Or, if the disappearance of the object (removal from the owner) did occur, it is advisable to somehow notify the owner of its movement or make it impossible to use it by outsiders or intruders.

Known keychain-alarm (RF Patent No. 86063, IPC H04B 7/00, G08B 13/00, publ. 08/20/2009), consisting of a housing, a microcircuit, a radio transmitter and a radio receiver, light signaling devices and / or display and sound signaling devices, as well as service buttons (keys, switches, and others). The key fob between itself and the other key fob (s) and / or between itself and another device with a radio channel carries out radio communication, in case of loss or attenuation of which the key fob (s) signal light and / or sound and / or vibro and / or other signals about loss (weakening) of such radio communications. Putting the keychain on the belt or putting it in a secure pocket and connecting it to the phone, the user will know about his loss or removal as soon as the keychain is about 10 m away from the phone, and when installing an increased level of danger using service keys (for example, public transport) and with a shorter distance between the key fob and the phone. It is possible to connect several of these key fobs to the phone, and then the phone will serve as a “base” for other key fobs. In this case, you need to place one keychain in a safe place (on the belt, in the inner pocket), and the other (others) in the wallet, purse and other necessary things. Then, in the event of the loss of a wallet or purse, the key chains in them, upon loss of connection with the “base”, will begin to signal and indicate to the owner the location of the lost or stolen things. A disadvantage of the known device is its limited functionality, due to the fact that if the distance (more than 10 m) between the key fob and the object of protection increases, this device will not work. In addition, the need for a constant stay of the device under electrical voltage leads to a relatively quick failure of its power supply (discharge of the battery or battery).

A device is known for protecting a cell phone from theft and loss (RF Patent No. 99293, IPC A45C 11/00, published on November 20, 2010), which is characterized by the fact that it includes a rectangular metal case of small size (up to 20 cm), which is attached for the user’s belt with a special fastener located on the device’s body, from which, according to the principle of a standard measuring tape, a strong cord is pulled out, the end of which is adapted for fastening to a special fastener, which is common on most mobile phone models element, as well as on the body there is a button, pressing which ensures the fixing of the lace on any state of its elongation. This device is not suitable for notifying the user about theft if the phone is located remotely from the user (not attached to the user with a cord).

A well-known mobile phone with the “help” function (Patent of Ukraine No. 83534, IPC H04M 1/02, publ. 09/10/2013, Bull. No. 17), comprising a housing with controls located on it in the form of a keyboard, screen, microphone, sound speaker , a satellite communications system, a digital photo / movie camera, a vibration mode system and a solar battery connected to a power supply unit, which is equipped with an additional button invisible to third parties or an emergency emergency call button located on the side of a mobile phone or in another convenient place, but it’s not next to the keyboard, but also contains an additional power source in the form of a tablet battery or the same small size battery design located inside the phone’s body, and when you press the specified button, the phone turns on with the microphone and connects automatically to the security signal reception panel, shutdown, which is possible only if a certain code is entered on the keyboard of the telephone from which the signal is received, and periodically changes and is known only to employees security concerns. If you remove its traditional power supply from the phone, it automatically switches to an additional power source and continues to work, even when you remove the SIM card. This device is useful only when you need to establish a steady continuous connection with the competent authorities in emergency cases (attack, traffic accident, the physical condition of the owner's phone has sharply worsened).

Closest to the proposed utility model is a mobile security alarm device (Patent of Ukraine No. 81947, IPC G08B 13/02, publ. 02.25.2008), containing an autonomous current source from which the power supply is supplied through the switch to all nodes of the device, sound emitter, the input of which is connected to the output of the amplifier, open circuit sensors. The device contains a control unit, made on the basis of the microcontroller, and an integrated motion sensor, the first output of the control unit, made on the basis of the microcontroller, connected to the input of the amplifier, the first input of the control unit, made on the basis of the microcontroller, is connected through the connector to the output of the break sensors, and the second input is to the output of the built-in motion sensor. The device comprises an indication unit, the input of which is connected to the second output of the control unit, made on the basis of the microcontroller. The disadvantage of this security alarm device is that it uses motion sensors that only allow you to determine the movement of the intruder, but do not provide detection of the touch of the intruder (thief) to the subject of protection and the ability to immediately respond to it (give an alarm). Also, the known device has a complex structure and contains an excessive number of additional elements - technical devices designed to perform various functions, which leads to an increase in the complexity of controlling the device.

The utility model is based on the task of improving the design of a security alarm device with the function of transmitting an alarm to a user's computerized device, in which, due to a new hardware solution, the security of the object is improved, the alertness of the owner of the protected object is improved by sending an audible alarm with simultaneous notification by means of wireless communication of signals to a user's mobile device with maximum simplicity about luzhivaniya devices and the possibility of carrying the object of protection.

The problem is solved in that a security alarm device with a function of transmitting an alarm signal to a computerized user device is proposed, comprising an autonomous current source, a control, alarm and indication unit, the input of which is connected to the control controller, and a security sensor, in which, according to the utility model, the control the controller is made in the form of a Bluetooth LE microcontroller, and at least one capacitive proximity sensor with active sensors is used as a security sensor shielded and the switching electrodes, which is connected to the selector platen and Bluetooth LE microcontroller, wherein the capacitive proximity sensor is combined on a single printed circuit board with a control unit, and alarm indication, Bluetooth LE microcontroller and the active screen formed as printed conductors on the board.

In addition, users' computerized devices are a smartphone and / or tablet computer based on Android or IOS, a laptop and / or a personal computer with installed software designed to connect to a Bluetooth LE microcontroller.

The use of a capacitive proximity sensor in this device allows you to register a touch to the object or approach to the object of protection (wallet, purse and others), inside which the proposed device is located and send an audio signal or information signal (to the device itself and / or to the user's computerized device).

The proposed alarm device with the function of transmitting an alarm to a user's computerized device has its own name - “Keeper”.

A utility model is illustrated in the drawing, where in FIG. presents a structural diagram of the proposed device.

The security alarm device with the function of transmitting an alarm signal to a computerized device contains an autonomous current source 1 supplying all elements of the device, a control, signaling and indication unit 2, the input of which is connected to a control controller, which is made in the form of a Bluetooth LE microcontroller 3, and a capacitive proximity sensor 4, which is connected to the selector of the reference capacitance 5 and Bluetooth LE by the microcontroller 3. The capacitive proximity sensor 4 is combined on the same printed circuit board with the control, signaling and indication unit 2 tion, Bluetooth LE microcontroller 3 and the active screen 6, made in the form of printed conductors on the board. The capacitive proximity sensor 4 has sensitive elements, for example, conductors 7 on the printed circuit board, which are connected through the electrode switch 8 to the control, signaling and indication unit 2. All of these elements are housed in a body of non-magnetic material to ensure the integrity of the device.

Bluetooth LE microcontroller 3 contains the following modules:

- Programmable Intel 8051 - single-chip compatible microcontroller;

- non-volatile program memory;

- random access memory;

- 2.4 GHz high-frequency transceiver compatible with Bluetooth v4.1 specification;

- A set of programmable general-purpose input-output lines;

- programming and debugging interface using the serial protocol SPI (Serial Peripheral Interface);

- pulse voltage converter.

This microcontroller is characterized by ultra-low energy consumption, which allows it to work from a conventional lithium battery (current source 1) of the CR2032 form factor for up to one year.

The functions of microcontroller 3 include communication with external computerized devices (smartphone / tablet / laptop / desktop PC / etc., hereinafter referred to as the host), namely, such functions: receiving control commands, transmitting status information sensor 4, the signal level (RSSI - Received Signal Strength Indication) and the charge of the power supply 1. Also, it provides control of all elements / modules of the device using input / output lines, for example, switches the reference capacitance for the sensor 4, selects the active electrode, reads signals from tactile to The buttons of the control, alarm and indication unit 2, and the capacitive sensor 4, provide a signal to the piezoceramic emitter and to the LEDs.

The control, indication and signaling unit 2 contains the following elements: a tactile button, which is tested programmatically and has many purposes in various operating modes of the device; two-color LED (displays short flash modes); a piezoceramic emitter that gives an alarm in the sound range (long squeak or siren with a frequency of ~ 4 kHz). The function of this unit 2 is to transmit alarms to the user's computerized device when communication is lost or when the proximity sensor 4 is triggered.

Using the selector of the reference capacitance 5, one of several reference capacitors is connected to the microcircuit of the capacitive sensor 4, which periodically compares it with the electric capacity of the sensor plates (electrodes). The human body has its own capacitance, the influence of which (for example, the approximation of the hand) on the electrodes is detected by the proposed device. Due to the ability to change the reference capacitance, it is possible to adjust the sensitivity of the sensor 4. This is necessary for cases when the environment around the device changes dramatically (it is located (the device) near the human body, for example, in a pocket, lies in a wallet or purse or in another object of protection )

The active screen 6 is a portion of the copper foil inside the printed circuit board, to which an electric field of the same polarity as on the electrodes 7 of the sensor 4 is connected. The field on the electrodes is repelled in the opposite direction to the active screen 6. Thus, it is possible to insensitive one or the other side of the device. This is necessary to prevent false positives (for example, from the body of the owner of the device when the device is in your pocket).

The proposed device may be in the following modes of operation:

- Active standby. At intervals of t1, the first LED flashes. In this mode, broadcasting on special Bluetooth LE channels (the so-called “advertising”) gives a notification about the device’s acceptance and readiness to establish a communication session. This notification is available to all hosts within range. If no communication with the device is established within N1 seconds, the device enters the passive standby mode.

- Passive waiting. In this mode, the device transceiver is turned off, minimizing the energy consumption of the power source. There is no light indication. Going back to active mode is possible only by pressing the button of unit 2 (or removing and installing the power supply).

- Work mode. It is activated if the communication session with the host is successfully established. At the same time, the device becomes inaccessible to other hosts, since (according to the Bluetooth LE specification) it disappears from advertising channels and switches to the mode of pseudo-random abrupt change in the operating frequency and traffic encryption. The second LED flashes at intervals of t2. In this mode, it is possible to control the device through special host software, for example, monitor the alarm status, battery level, change the sensitivity of sensor 4, select the sensitive side of sensor 4, search for the device within the communication radius by the signal level that is being monitored, or another.

- Security mode. It is activated upon command from the host. In this mode, the capacitive sensor 4 is switched on. The first LED flashes with an interval of t3. When the sensor is triggered, an alarm message is sent to the host, a signal is supplied to the piezoceramic emitter. The alarm lasts N2 seconds, then the device returns to armed mode again.

- Communication loss mode. It is activated in case of interruption of the established connection. In this case, the software on the host gives an alarm about the loss of communication, the device goes into standby mode for N3 >> N1 seconds (to enable reconnection). After the end of N3 seconds, if the connection has not been restored, the device returns to passive standby mode.

It should be noted that the described operating modes and indications are set programmatically and can be changed in the future as a result of adding new functionality.

The proposed device is used as follows.

Special software is installed on a computerized device of a user having a Bluetooth communication module (smartphone and / or tablet computer based on Android or IOS, laptop and / or personal computer), namely a mobile application that works online and is designed to connect to the proposed security alarm device. The device is turned on and the appropriate program of the device is selected. The device is placed in an object of protection, for example, in a purse, with the insensitive side to the back of the purse. If the device is in armed mode, then during unauthorized actions (for example, when a man purse is stolen), a capacitive sensor is triggered, which sends a signal to a piezoceramic emitter (the device gives a signal in the audio range) and to the software of the mobile application, which in turn implements the sound and an information signal to the user's computerized device. Thus, the owner of the man purse will be instantly informed of unauthorized actions with his property.

This device is multifunctional, mobile, fairly easy to maintain, works without replacing the power source from 10 to 12 months and provides the opportunity to increase the reliability of object protection, protect remote objects from the owner, improve the efficiency of notifying the owner by transmitting sound to this device or sound and informative signals to the computerized device of the user-owner.
