Description

The utility model relates to the field of security alarms of vehicles using a GSM cellular communication channel and can be used in security systems of vehicles set as an alarm as an additional security device that controls violation of the vehicle's integrity, or as the main alarm monitoring the state of the vehicle .

As you know, now the most practical is the alarm on the phone, which when triggered alerts about the alarm. The alarm system via telephone is controlled by two-way communication, and also notifies the owner on a mobile phone about unauthorized access to an apartment, office, home, warehouse, garage, and so on.

The first alarm through a mobile phone appeared in the nineties. Initially, radio signal transmission technologies were used, but soon several shortcomings of such systems were identified, the main one of which was the limited range of the radio network. In 2002, the first warning systems appeared in our country that did not have such problems, because they used a cellular signal to transmit GSM.

GSM alarms via a mobile phone quickly captured the market for security systems, because they were simple, reliable and convenient devices. The management of GSM signaling from a mobile phone is very interested in many consumers, due to its independence and low cost of use.

The use of mobile as a receiver of alarm signals from the warning system has become the second purpose of all mobile phones. GSM signaling to the phone, allows you to remotely configure or check the main control unit, sensors, alarm sirens, take photos, video images from the guarded object, and so on.

The development of mobile communications and the introduction of various applications for phones, smartphones and tablets has allowed the development of new multifunctional alarm systems - a security system with CMC notification. Its difference from the usual burglar alarm is the presence of a GSM module in the control panel and the ability of the owner to receive CMC messages about the status of the system. As a rule, a conventional burglar alarm consists of a set of sensors, a control device and warning devices. In case of penetration into the protected area, security sensors will work and the base unit will generate a signal that will turn on the siren and indicator light. In this case, only those persons who are within the zone of the sound emitter will know about the violation. And the well-known new security systems with a GSM module include the following components: a control and reception device with a mobile communication module, magnetocontact sensors, passive infrared motion sensors and an internal warning system.

For example, today solutions are widely known regarding signaling devices (alerts) about the presence of contact with the vehicle, the presence of foreign objects and the detection of human presence outside and inside the vehicle.

So, from JPH 05112207 (publ. 1993.05.07) a car owner’s warning device is known that contains a photosensor for contactlessly sensing the distance from the road surface located on the surface of the body. Signals from the sensor are supplied to the means for estimating the length of time, and if the light is blocked for more than a predetermined time, the alarm means is turned on. The car owner can receive an alarm signal in a place remote from the car if something blocks the light flux in the vicinity of the car, for example, if the car body is in contact with a person, and if, at the same time, the signal issued by the photosensor exceeds the set value. The signal is transmitted to the owner through regular telephone communications.

CN 202193055 (publ. 2012.04.18) describes an automobile anti-theft system with functions for determining the temperature and presence of gas, which contains a microcomputer, a power supply and an LCD display, and the input port of the microcomputer is connected to an infrared human body heat detector, as well as a temperature sensor and a sensor oxygen, which are located in the car. An infrared detector is located at the top of the driver's seat. The anti-theft system is equipped with a GPS module and a module for sending GSM signals, vehicle location information and other information can be sent to the car owner’s mobile phone when an outsider enters the car.

CN 103886727 (publ. 2014.06.25) discloses an automatic alarm and anti-theft system related to a traffic accident, including various sensors, a manual control button, a microcomputer, a GPS and GSM unit. The system has a high level of circuit integration, so the tilt acceleration sensor, pressure sensor, GSM and GPS modules, infrared sensors of the human body and flame, and the temperature sensor are combined as a whole.

No. 6,044,256 (publ. 2000.03.28) describes a warning device having an infrared optical communication circuit. In a portable telephone used as a terminal device, an infrared optical communication circuit includes a light emitting section for emitting infrared rays and a photodetector section for detecting infrared rays. The controller compares the infrared rays emitted by the light-emitting section with infrared rays, which are reflected by the reflective plate and detected by the photodetector section, and detects infrared cut-off information based on the comparison result. Information about the cutoff of the infrared ray can be transmitted from the transmitter-receiver to another terminal device (telephone), output in the form of voices from the audio transmitter-receiver, displayed on the display or stored in memory, which makes it possible to detect the movement of a person or objects.

WO 02080514 (publ. 2002.10.10) discloses a burglar alarm device, which comprises a detection sensor, detecting electronics and alarm means, provided with an audible alarm device, which are connected to a portable digital information medium, which may be a telecommunication device or a handheld computer. The detector sensor detects an infrared signal emitted by the object to be monitored. The detection sensor is, for example, an infrared detector, but it can also be an infrasound detector that responds to sounds below the hearing range caused, inter alia, by opening doors or windows. When the device is connected to a mobile phone, the system can send an alarm in the form of a message to another phone on the mobile network.

The considered security systems for warning the car owner about unauthorized access to his vehicle have serious drawbacks. For example, the use of sensors for emitting infrared rays requires that the receiver of these rays, and this receiver is a mobile phone, always be in the area of access to these rays. That is, the mobile phone is exposed in space so that the rays from the sensors come in direct line of sight to the phone: for this, the receiver on the phone is tuned to the vector of infrared rays from the sensor / co. The appearance of a foreign object on the communication line of sensors with a mobile phone leads to a disconnection and the inclusion of alerts in a mobile phone, including sending a CMC message. This is inconvenient, since the car owner must always be close to his mobile phone, which is stationary located, for example, on a table.

The use of thermal sensors to detect an outsider in the car (at the moment of its non-use by the owner) - infrared heat detectors of the human body - is designed to prevent the hijacker from applying special measures. And if the hijacker is dressed in reflective clothing with an external temperature corresponding to the temperature of the environment in the car, then taking into account the error of the sensors, the system may not respond to breaking the car. For example, an infrared detector is located in the upper part of the driver's seat, but the use of special materials reflecting infrared radiation leads to a sensor failure. Examples include US 5281460 or an infrared camouflage coating in which a strip pattern is applied to a porous nylon mesh. The bands are coated with silver, copper or pigment. Or material from US 4495239, which is a camouflage material with a wide spectrum of action, based on a layer of textile material, on the surface of which a metal reflective layer is deposited by gas deposition, and then camouflage coloring, or material from US 4467005, made on the basis of a support mesh, on both sides of which there is a carrier web with a metal coating reflecting infrared radiation, etc. Therefore, when the hijacker comes in contact with the seat, the sensors may not work in that short period of time, which is enough to steal a car.

The use of an infrasound detector that responds to sounds below the audible range caused, inter alia, by opening doors or windows, requires fine tuning with filtering a wide range of external sounds that are below the audible range and not related to sounds made by opening doors or windows or the hood of the car. This applies to difficult to install complex systems. The use of such systems is advisable if the car is stored in an isolated box or garage without access to external sounds. When storing a car in a public parking lot or near a house, such sensors are triggered by any noise in this range.

The use of oxygen sensors in the cabin is a complex circuit because of the use of bridge circuits in such sensors, such sensors are insensitive at low temperatures and begin to work when the temperature rises to a level that is not a level of human activity.

The use of a photosensor located on the surface of the body for non-contact sensing of the distance from the road surface (the distance from the sensor to the road surface) is closely related to the load on the vehicle's suspension when the driver sits in it. It is clear that a driver's weight of 80 kg or more will lead to compression of the suspension springs by a certain amount, which will affect the controlled distance. If the weight is less (teenager), the compression of the springs can be perceived as the value of the sensor error. Or in winter, snow can sweep under the body, which will also be reflected in the distance.

In general, none of the considered alarms, as owner’s warning systems, works as a security alarm, that is, does not allow an attacker to get into a car and steal it. It’s just a warning system that something is wrong with the car and it is necessary to approach the car. If an attacker sets out to steal a car, he will do it, regardless of what information and from which sensors went to the car owner’s phone. It takes minutes to steal, and sometimes it takes tens of minutes to get to the car. This time difference always works against the car owner. But, in essence, such a notification to the car owner makes sense, since it allows him not to lose time and timely use the help of special services. In this regard, it is important to choose the information that the car owner receives and to select sensors or systems that in any case determine a violation of the integrity of the vehicle that was armed, and which is difficult or impossible to deceive. The value of this choice becomes important if the car owner is located at a considerable distance from the car and cannot prevent theft, but can, having learned about it, immediately inform special structures.

Thus, it is known a device for remotely alerting the owner of a violation of the inviolability of his vehicle, which contains an object part located secretly in the vehicle, which contains a plastic case in which a microcontroller is located, to which an accelerometer, a power source (battery) and a GSM module for transmitting messages are connected to the receiving and controlling part of the cell phone of the vehicle owner (RU 80804, B60R 25/00, G08B 13/00, published on 02.27.2009). This decision is made as a prototype.

In a well-known solution, the car owner sends a signal through the cell phone to turn on the security system. In the object part of the system, the GSM module receives a signal from a cell phone and transmits to a microcontroller. The microcontroller analyzes the received command and puts the vehicle under protection and remembers the accelerometer at the time of delivery. Subsequently, the microcontroller analyzes the accelerometer readings and, with a sharp change in acceleration (position), transmits an alarm signal to the GSM module, which establishes communication with the car owner’s cell phone. By the established communication, the microcontroller transmits a message about the incident to the GSM module and then to the car owner.

- прибор, измеряющий проекцию кажущегося ускорения (разности между истинным ускорением объекта и гравитационным ускорением). Как правило, акселерометр представляет собой чувствительную массу, закрепленную в упругом подвесе. Отклонение массы от ее первоначального положения при наличии кажущегося ускорения несет информацию о величине этого ускорения. Принципиально акселерометр состоит из пружины, подвижной массы и демпфера. Пружина крепится к неподвижной поверхности, к пружине крепится масса. С другой стороны ее поддерживает демпфер, который гасит собственные вибрации груза. Во время ускорения массы деформируется пружина. На этих деформациях и основываются показания прибора. Акселерометры, например, встроенные в автомобильные видеорегистраторы, различают тревожные события, такие как резкое торможение, ускорение, столкновение, резкие повороты и вращение, то есть те движения, которые приводят к смещению массы и нагружению пружины.

- a device that measures the projection of apparent acceleration (the difference between the true acceleration of an object and gravitational acceleration). As a rule, an accelerometer is a sensitive mass fixed in an elastic suspension. The deviation of the mass from its initial position in the presence of an apparent acceleration carries information about the magnitude of this acceleration. In principle, the accelerometer consists of a spring, a moving mass and a damper. The spring is attached to a fixed surface, the mass is attached to the spring. On the other hand, it is supported by a damper that dampens its own vibration of the load. During mass acceleration, the spring is deformed. These deformations are the basis for the readings of the device. Accelerometers, for example, built into car DVRs, distinguish alarming events, such as sudden braking, acceleration, collision, sharp turns and rotation, that is, those movements that lead to mass displacement and spring loading.

A new accelerometer circuit has also been developed. A fixed partition with conductors allotted to the side is attached to a fixed body on elastic attachments that allow movement within certain limits. These taps are placed between the contacts, which take readings. Thus, in this embodiment, the accelerometer can be made miniature (for example, built into a cell phone). Piezoelectric accelerometers are also used.

A feature of any accelerometer is that, as a device, it relates to structures with moving elements. For such structures, the mobility of the elements is directly related not only to the method of fixing the accelerometer, but also to the temperature regime of the external environment and to the dimensions of the device itself. For example, low temperatures can move the sensor threshold to a higher level, which can lead to a malfunction of the sensor or lead to unreliable results. As simple instruments, accelerometers require a very complex calibration and the regularity of the necessary repeated calibrations. In addition, accelerometers have a wide range of sensitivity (in working condition). In this regard, when setting up a car, sensitivity is adjusted to prevent the sensor from turning on when the body vibrates from the wind or from the air flow of a nearby car, from blows of falling branches or a coma of snow from a tree, etc. .. that is, they try to remove the influence of some reasons not related to the event of theft. With this adjustment, as a rule, the start of the accelerometer’s response is changed, which leads to the beginning of its operation with real vibrations or vibrations similar to the start of the car’s movement. And smooth movements, such as the smooth lifting of the vehicle by the "working arm" of the tow truck, become imperceptible to the sensor.

In this regard, the use of only an accelerator in the security system does not guarantee the reliability of this protection in some life cases.

Practice shows that in a warning system, as a rule, there should be at least two sensor signals that are different in nature and respond to situations that are different from each other. In any case, if one of the sensors does not work, then the probability of the failure of the other sensor in this case is extremely small. The systems and devices described in the prior art section are built on this principle. In known systems and devices, heterogeneous sensors always work independently of each other, but are associated with a common processor unit. The inconsistency of the functions of the sensors is not a consequence of the increased likelihood of triggering due to a violation of the integrity of the vehicle. This incoherence is determined by the fact that the main warning in such systems is the use of sensors with such mismatching functions that an attempt to bypass one of the sensors without fail leads to the inclusion of another sensor. At the same time, the goal is not to prevent theft or entry into the vehicle, but the task is to maximally alert the car owner about the violation of the space of his car.

The only question is the choice of another sensor - this sensor must respond to circumstances for which it is practically or with a high degree of probability impossible to change or adapt to it in real life.

This utility model is aimed at achieving a technical result, which consists in increasing efficiency and guaranteed response by adding a control function to touch the glass or a sharp change in its transparency.

This utility model is aimed at achieving a technical result consisting in the creation of a vehicle immunity control device that responds to a sharp change in the transparency of the glass to remotely alert the owner of a dangerous approach to his car.

The specified technical result is achieved in that the device of remote notification of the owner about the violation of the inviolability of his vehicle, containing a housing made of polymer material fixed to the vehicle in the form of a box in which a microprocessor, a power source in the form of a battery and a GSM module for transmitting messages to the reception the control part of the mobile communication means of the vehicle owner, characterized in that it is equipped with a touch sensor configured to react by touching the outer surface of the vehicle glass, the housing is adapted to be attached to the inner surface of the vehicle glass, two slots are mounted on one side of the housing to accommodate a USB connector for charging the battery, the charge controller of which is brought out on one side of the housing, and for the switch / switch of the sensor function, and on the other side there is a connector for connecting the antenna, the GSM module is made with a seat for the SIM card and with the possibility receiving a call from a mobile communication device to start the operation of the sensor sensor and sending SMS messages to the vehicle owner’s mobile communication device when environmental conditions change using the sensor sensor signals, and the sensor sensor consists of an IR LED and an IR photodiode used to receive modulated IR -signal reflected from objects brought to this sensor, which are placed opposite the through hole in the housing on the side of attachment of the latter to the inner surface of the glass conveyor tno means.

In a preferred embodiment of the device, an accelerometer connected to the processor is placed in the housing, a socket for accommodating the accelerometer function switch / on is located on the housing, and the GSM module is configured to send SMS messages to a mobile communication device.

The present utility model is illustrated with a specific example of execution:

in FIG. 1 is a general view of a device for remotely alerting the owner of a violation of the integrity of his vehicle;

FIG. 2 is a block diagram of the device of FIG. one;

FIG. 3 - layout of the elements of the device on the circuit board on one side;

FIG. 4 - layout of the elements of the device on the circuit board on the other side.

According to this utility model, a device is considered to remotely alert the owner of a violation of the inviolability of his vehicle due to either the presence of the intruder in the glass area of the car or the presence of movement in this car.

In the general case, this device comprises a housing 1 made of polymer material fixed to a vehicle in the form of a box in which a microprocessor 2 (with the function of a processor controller) is located, to which an accelerometer 3, a sensor 4, a power source in the form of a battery 5, and a GSM module are connected 6 for transmitting messages to the receiving and controlling part of a mobile communication device (not shown) of the vehicle owner.

The small case is made with the possibility of its attachment to the inner surface of the glass of the vehicle (for example, windshield or from the driver's seat). The case is attached to the glass with a transparent double-sided tape, another adhesive or a suction cup or other means from the arsenal used to fix devices on smooth surfaces in the car. A through hole 7 is made in the housing cover (or on its other side, it all depends on which side the body is attached to the glass).

The touch sensor is designed to respond to touch or dimming of the outer surface of the glass of the vehicle. The sensor consists of an IR LED 8 and an IR photodiode 9 used to receive a modulated IR signal reflected from objects brought to this sensor, which are placed opposite the through hole in the housing on the side of the latter's attachment to the inner glass surface of the vehicle. Thus, if the intruder approaches the glass on the placement side of the device body, this will be the basis for the sensor to respond to changes in the lighting situation and to issue a signal to the microprocessor.

The touch sensor responds to touch on the outer surface of the glass. At the same time, it requires holding for a set period of time for operation, thus protecting against reaction to wipers is implemented. The touch sensor does not respond to water splashes. However, it reacts to the appearance of any objects, which causes false positives. The touch sensor does not respond to the snow layer smoothly accumulating on the glass, however, it responds to the movement of snow lumps sliding on the glass. The touch sensor is illuminated by an LED. When configuring the touch sensor, you can adjust its sensitivity, response time to touch. Thus, a slow or gradual change in the light load on the surface to which the infrared radiation is directed does not affect the sensor, and a quick change in illumination leads to the operation of the sensor.

The sensor consists of an IR LED (KP-2012F3C) and an IR photodiode (KPTD-3216SURC). The operation of the sensor is based on the reception by the photodiode of an IR signal reflected from objects brought to the sensor. In this case, to exclude background illumination, a modulated IR signal is used. The sensor does not respond to the absolute value, but to a change in the magnitude of the reflected signal, due to which it is continuously reconfigured (calibrated) and maintains operability when dirt or dust gets on the glass surface.

Power supply: the device is powered by a built-in li-pol battery 5, which ensures the operation of the sensor and accelerometer. To charge the battery, use a USB connector 10 (for example, microUSB connector). Between the USB connector and the batteries, a charge / discharge controller 11 is inserted in the circuit, showing the degree of charge and / or the need for recharging with a light indication.

The GSM module is connected to the seat 12 for the SIM card and with the possibility of receiving a call from a mobile communication device to start the operation of the touch sensor and accelerometer and sending SMS messages to the mobile communication device of the vehicle owner when external conditions change according to the signals of the sensor and accelerometer.

Three sockets are mounted on one side of the case for accommodating a USB connector 10 for charging a battery, the charge controller of which is displayed on one side of the case, and for a number of switches: slot 13 for the accelerometer function switch / switch and socket 14 for the sensor sensor function switch / switch , and on the other side - connector 15 for connecting the antenna 16.

All components of the device: GSM 6 module (controller on the SIM800H chip), a touch sensor arranged in such a way that it is triggered by touching the opposite side of the glass on which the device is mounted, accelerometer 3 (on the LIS3DH chip), which can detect small movements and device tilt, connector (seat 12) for installing a SIM card (SIM ICA-501-006-F7), SIM chip (SIM_chip) 17, li-pol battery 5, toggle switches 18 and 19 are mounted on a common board 20, reinforced in the case. In the future, the RFID tag and the GPRS module may additionally be placed on the board 20. At the same time, a GSM controller, a connector for installing a SIM card and a battery are placed on one side of the board. And on the other - an accelerometer, a SIM chip and a touch sensor. On the first side of the board, connectors for strengthening the USB port and switches and connector 15 for connecting the antenna (SMA-JR) are also mounted.

Two switches 18 and 19 (SS12F21G5-G) with on / off function are used as switches. The toggle switch 18 can be switched with a finger, and it serves to turn on / off the device. The toggle switch 19 is also available for switching with a finger, and serves to enable / disable the accelerometer function.

Battery 5 with a charge-discharge controller provides autonomous operation of the device for 1 year. Control switches allow you to select the desired operating mode.

The device in question is intended to remotely alert the car owner. The device is a GSM-controller with a touch sensor and an accelerometer, which is mounted on the inner surface of the windshield of the car. The touch sensor responds to touching the outer surface of the glass, the GSM module makes a call and sends an SMS message to the user's phone.

The accelerometer is built-in and responds to small slow movements, such as occur when lifting the car to the tow truck or when jacking the car.

Work algorithm:

While the switch is in the off position, the device is turned off and does not discharge the battery. After the switch is turned to the on position, the device waits 5 minutes for a call to its number. If a call arrives, the device sends an SMS message in response that the number has been saved as a user number. If the number has already been set, the device sends an SMS message with a greeting and indications of the battery charge to it.

The touch sensor is always on when the device is on, i.e. the toggle switch 18 is in the on position. The operation of the sensor is accompanied by a blinking LED. After the sensor is triggered, the device sends an SMS message to the user’s number with the following content: “Please go to the car. The touch button worked, ”then rings 3 times. If the user drops the call or picks up the phone, calls are terminated.

The accelerometer is turned on when the toggle switch 19 is in the on position. After registering the movement with the accelerometer, the device sends an SMS message to the user’s number with the following content: “Please go to the car. The evacuation sensor has worked, ”then it rings 3 times. If the user drops the call or picks up the phone, calls are terminated.

The microprocessor with the control program receives data from the accelerometer and the sensor, determines from it the fact of movement of the device, the fact of the sensor being triggered, in accordance with the laid down algorithm, sends a command to the GSM module to send the user an SMS message or phone call.

The main and potential functions of the device:

- Call the owner of the car using the touch sensor;

- Notification of the owner of the car about the operation of the accelerometer due to evacuation;

- Notification of the owner of the car about the operation of the accelerometer due to an attempt to commit illegal actions with the car, for example, removing the wheels - alarm;

- When the accelerometer is triggered - notification of other device owners in a certain radius about the operation of the tow truck;

- “Parental control” - the ability to request GPS coordinates of the vehicle.

- When RFID tags are installed in the device, automatic permission to enter the car into a closed territory (residential yard, parking).

This utility model is industrially applicable and can be manufactured using the element base used in the manufacture of electronic security systems. The use of the accelerometer allows you to register the vehicle’s movements related to its inclination or movement, in which there are inertial effects that form acceleration. When the vehicle is tilted or when it is lifted by the tow truck, an oscillatory process occurs (the suspension reacts to changes in the load on the wheels), which excites the mass and leads to the manifestation of inertial nodding. This is enough for the movable element of the accelerometer, regardless of its design, to react and outrage either the spring or the piezoelectric element, or change the distance between the contact elements. The use of a touch sensor greatly increases the security of the vehicle due to its location and the function of scanning the light flux on the glass. Regardless of the professionalism of the intruder, in order to steal a vehicle it is necessary to approach the windshield or the driver’s side (checking the condition of the driver’s seat and the presence of a mechanical anti-theft system), and to enter the car you need to be near the driver’s glass. Shadow flashes provoke a touch sensor and turn on an alert to the car owner. Thus, both functions in the claimed device are selected so as to best match the situation that occurs when trying to steal a vehicle. This allows you to increase efficiency and guaranteed response by supplementing the motion control function with a control function for touching the glass or a sharp change in its transparency.
