The mobile communications support unit 1 is a radio device that receives, transmits, and converts a radio signal. Reception and transmission of radio signals occur as part of the cellular network. A radio signal is transmitted by radiation from its antenna, which is usually part of this unit. The conversion of the radio signal provides the presentation of information in accessible to other units that are part of the mobile phone. Also, the mobile communications unit may provide data transmission over the Internet.

The range measuring unit 2 is a device whose main function is to determine the distance from the source to the object. The principle of operation is based on the application of location using radio waves, light waves or acoustic (sound) waves. The range measuring unit 2 is capable of emitting a sounding signal, registering a signal reflected from the object, measuring a delay time between the sounding and reflected signal. The probe signal is, for example, a radio wave or an ultrasonic wave (hereinafter referred to as ultrasound). The reflected signal in the form of radio waves or ultrasound waves is recognized by the range measuring unit 2 in a special way. Devices operating in a similar manner are known in the art. An example of such a device is a locator (the definition of a locator is given, for example, on the site http://dic.academic.ru/dic.nsf/bse/104369, accessed 08.07.2016).

The unit for measuring the speed of objects 3 is a device whose main function is to measure the speed of an object. The unit for measuring the speed of objects 3 works on the basis of the Doppler effect (the essence of the Doppler effect is given, for example, on the website http://dic.academic.ru/dic.nsf/bse/85506, accessed 08.07.16). The unit for measuring the speed of objects 3 emits a probe signal, registers the signal reflected from the object, and measures the change in the frequency of the reflected signal with respect to the probe frequency. The probe signal is, for example, a radio wave or an ultrasonic wave. The reflected signal in the form of radio waves or ultrasound waves is recognized by the object speed measuring unit 3. An example of an object speed measuring unit 3 is the Doppler radar (the definition and operation principle of the Doppler radar can be found, for example, on the website http://dic.academic.ru/dic .nsf / ntes / 1494, accessed July 8, 2016).

The control unit 4 is a controller that exchanges information and issues commands during the interaction between the range measuring unit 2, the object speed measuring unit 3, the control value storage unit 5, the telephone user alert unit 6, the traffic sign recognition unit 9, the unit determination of surface irregularities 10. The main function of the control unit 4 is the processing of incoming information and sending a special command to the unit warning the telephone user about the danger 6. The incoming information is data obtained from the unit for measuring the speed of objects 3, the unit for measuring range 2, the unit for storing control values 5, the unit for recognizing traffic signs 9, the unit for determining surface irregularities 10. The principle of operation of the control unit 4 is based on a comparison of current values received from the unit for measuring the speed of objects 3, the unit for measuring the range 2, the unit for recognizing traffic signs 9, the unit for determining the roughness of the surface 10 with the values received from the unit for storing control values 5. When certain conditions are met, the control unit 4 sends a special command to the warning unit of the telephone user about the danger 6.

The control value storage unit 5 is a device that stores control values and transfers them to the information processing unit.

The warning unit of the telephone user about the danger 6 is able to provide notification to the user of the mobile phone about the danger or obstacle. The hazard warning unit 6 for the telephone user consists of a light indicator, or a speaker, or a vibration system. The indicator light may be made, for example, from an LED. The speaker has a sound alert function. The vibration system provides tactile notification.

The traffic sign recognition unit 9 operates on the basis of the principle of recognition of road signs. The principle of recognition of road signs includes image acquisition, image conversion, the use of a threshold filter to highlight a traffic sign in a photograph, and analysis of a road sign highlighted in the image. The image is acquired by the camera or the traffic sign recognition unit 9. The latter extracts the frame from the video obtained using the video camera. Further, the road sign recognition unit converts the image into a format suitable for applying the threshold filter, for example, by highlighting areas with characteristic combinations of colors, numbers and shapes, for example, a white circle concentrically aligned with the red ring so that the radius of the circle is the inner radius of the ring (no traffic sign). Further, the traffic sign recognition unit applies a threshold filter. The threshold filter compares the converted image with the reference image. Reference images can be stored in control block 5 or in a block for recognizing traffic signs 9. If a certain level of correspondence between the reference image and the converted image is exceeded, the block for recognizing traffic signs sends data about the traffic sign to control unit 4 (such a method for recognizing road signs is known from the prior art and is described, for example, in the source https://habrahabr.ru/post/61048/, accessed July 14, 2016). The traffic sign recognition unit 9 may include a camera or use the camera integrated in the telephone.

The surface irregularity detection unit 10 is a device whose main function is to determine the surface irregularities on which the user moves by a mobile communication and data transmission device. The surface irregularity determination unit 10 measures the distance to the surface and reveals a sharp change in the distance to the surface along which the user moves with a mobile communication and data transmission device. To measure the distance, you can use a laser rangefinder. The unit for determining surface irregularities 10 compares the distances to various close to each other surface points to determine surface irregularities, for example, pits, borders. If a significant difference in the distances to these surface points is detected, the surface roughness determination unit 10 sends information about the surface roughness to the control unit 4.

In this way, a mobile phone user is warned of danger.

The warning unit of the telephone user about danger 6 receives a command from the control unit 4 and notifies the telephone user. To notify the user on the telephone user alert unit 6, the indicator light flashes or blinks, or the mobile phone vibrates, or an audible alert sounds, or a message appears on the screen.

The traffic sign recognition unit 9 recognizes traffic signs. The traffic sign recognition unit 9 receives images, converts images, applies a threshold filter to highlight a traffic sign in the photograph, analyzes the road sign highlighted in the image. The camera or traffic sign recognition unit 9 receives the image. The latter extracts the frame from the video obtained using the camcorder. Further, the road sign recognition unit converts the image into a format suitable for applying the threshold filter, for example, highlights areas with characteristic combinations of colors, numbers and shapes, for example, a white circle concentrically aligned with the red ring so that the radius of the circle is equal to the inner radius rings (no traffic sign). Next, the traffic sign recognition unit applies a threshold filter. The threshold filter compares the converted image with the reference image. Reference images can be stored in control unit 5 or in a traffic sign recognition unit 9. If a certain level of correspondence between the reference image and the converted image is exceeded, the traffic sign recognition unit sends traffic sign data to the control unit. The traffic sign recognition unit 9 may include a camera or use the camera integrated in the telephone.
