Description

The utility model relates to security-recording systems for monitoring information channels of mobile and stationary objects in real time with the possibility of registering the occurrence of emergency situations and fixing the state of the controlled parameters of the object at the time of its occurrence, the previous and subsequent time interval. More specifically, the system is designed to control the parameters of movement and the state of the vehicle (TS), as well as to provide information support to the emergency response services when analyzing the circumstances of a road accident.

In modern conditions of motorization of society and the need for car insurance, one of the important areas is the creation of timely, qualified and objective description of the circumstances of an accident and the protection of objects. Currently, there is no device that fully supports the performance of these tasks. The installation of routing data recorders (tachographs) only partially affects the range of these tasks even when using digital technologies, because the tachograph is an automatic on-board device that is installed instead of the speedometer or together with it and intended only for continuous indication and recording of the speed, vehicle mileage and periods of work and rest of the vehicle driver. Materials about these devices are presented, for example, on the Web-server of the magazine "Behind the Wheel".

So, in patent US 4188618, G 08 G 17/00, 02/12/1980 a digital tachograph for recording vehicle parameters is described, comprising a vehicle dynamic parameter meter installed on board the vehicle, which includes a vehicle speed meter and is capable of continuously recording digital data corresponding to other measured vehicle parameters (engine shaft rotation speed, fuel consumption, etc.), a digital display configured to promptly selectively display instantaneous values of the measured vehicle parameters, a data storage unit made with the ability to install on board the vehicle for continuous reception and recording of signals corresponding to the measured parameters of the vehicle, a computer terminal installed outside the vehicle, as well as a communication channel configured to quickly transmit selected fragments of vehicle parameters from the onboard storage unit to the computer terminal, wherein

the computer terminal is configured to selectively read data from the vehicle.

The specified technical solution is implemented, in particular, in the digital recorder BR-6800/6802 from Baoruh Electronic Co, Ltd. (Taiwan). It includes a 32-bit microcontroller, 128 KB flash memory and 8 MB hard disk memory expandable to 128 MB, has 16 inputs for recording digital signals, 8 inputs for recording analog signals and 7 digital outputs. Information read from flash memory can be transferred via communication channels to a processing center for subsequent analysis ().

The BR-6800/6802 recorder is a universal device that can be installed on various types of vehicles as additional electronic equipment. On the one hand, such versatility is the advantage of this device, and, on the other hand, its disadvantage, since it causes its high cost. In addition, the BR-6800/6802 registrar is not effective enough in case of an accident, since a more complete set of recorded motion parameters and a higher resolution of recordings than the aforementioned registrar is capable of are required in the emergency section (from the beginning of an accident to a complete stop of the vehicle). In addition, it should be possible to clearly determine the moment of occurrence of an accident in order to minimize the stored amount of information and its transmission.

The decision support system for the US 2002/0103622, G 06 F 15/00, 08/01/2002 has the ability to transmit data about the state of the vehicle, driver and passengers during an accident. This system includes vehicle motion parameters meters installed on board the vehicle, sensors configured to determine the state of the vehicle components and assemblies and biometric data indicating the physical conditions of the vehicle driver and passengers, as well as other on-board measuring instruments connected via a common bus to the on-board data processing subsystem, including a data processing unit connected via an interface to a common bus, an information storage unit, a vehicle location unit, for example GPS -a receiver and a transceiver with an antenna for wireless communication with a control center including an accident data collection and processing subsystem that is connected to external sources of information related to one or several standard communication networks, for example, a GSM mobile radio network Accidents, which may be emergency and medical care centers, emergency rooms, hospitals, etc., while the information storage unit, the vehicle location unit and the transceiver are connected to the processing unit and data, and the center

The control unit is capable of transmitting data to emergency centers, rescue services and other organizations that have the forces and means for prompt response and emergency assistance to victims of road accidents.

The disadvantage of this system is that it does not have the means to use additional on-board equipment (on-board meters, data processing subsystem, etc.) in the normal mode of operation of the vehicle, and not only for fixing the parameters characterizing the accident. This significantly narrows the scope of this equipment, since, as a rule, manufacturers and owners of vehicles prefer additional equipment of double (or triple) use, which can be used both in normal mode and in traffic accidents.

An example is the GPS receiver, which is used simultaneously as part of the security and anti-theft systems of the vehicle and on-board navigation systems. An even wider and multifunctional application is now found in a cell phone. In addition to its intended use as a means of mobile communications, it is widely used for transmitting telemetry data and control actions from the vehicle and vice versa.

A known system for recording motion parameters and vehicle conditions according to patent GB 2055469, G 07 C 5/08, 07/15/1980.

The specified system contains an analog-to-digital converter (ADC) installed on the vehicle, made with the possibility of digitizing analog signals from a speed meter and accelerometer, a master oscillator providing input to the ADC with a given clock frequency of the measured values of speed and acceleration, a shift register containing a set of memory cells, sufficient to record the parameters of the vehicle during the duration of the accident and made in the form of a removable unit, providing forwarding recorded in its data to an external microprocessor, as well as a blocking device configured to interrupt the flow of digital data coming from the ADC to the shift register when the vehicle speed reaches zero, and an internal microprocessor connected to the shift register and configured to control the blocking device through the block delays.

The main disadvantage of this system is the lack of technical capabilities in it for operational remote sensing of recorded data, subsequent processing, analysis and decision support to assist the driver and passengers of the vehicle in an accident.

The closest analogue of the claimed invention is a system for collecting and analyzing data on a traffic accident RF patent No. 2222830 G 07 C 5/08, B 60 R 16/02.

In addition to the well-known system for collecting and analyzing data on accidents, this system contains a navigation unit for measuring vehicle motion parameters, which is part of the on-board measuring unit, an ADC, a memory register, and a resolving device, a navigation unit, a common bus to which the ADC input is connected and outputs of the navigation unit and the on-board measuring unit, the on-board measurement data processing unit, the control command generation unit and the data format conversion unit connected in series, non-volatile memory, b a data reading lock and a wireless data transmission unit, a traffic accident data collection and analysis center, comprising a wireless communication receiver connected in series via radio with a wireless data transmission unit installed onboard the TC, a primary data processing unit, a secondary data processing unit and an acceptance support unit solutions made with the possibility of information support of emergency medical services and rescue, while the ADC output through the on-board measurement data processing unit is connected to the input to the memory register, the output of which is connected to the input of the data format conversion unit, the control input of which, through the control command generation unit, is connected to the output of the solver, the input of which is connected to the ADC output.

This system makes it possible to restore a more complete picture of road accidents from data obtained by various airborne meters, as well as the possibility of an operational analysis of these data using expert information from external sources in order to support decision-making on emergency medical care and on saving the driver and passengers injured in an accident.

However, the disadvantage of this system is that it is tied to a GPS navigation system, which requires the interconnection of all system nodes to the navigation unit. Specifically, this is expressed in the need to include in the system such nodes as a wireless data transmission unit, a traffic accident data collection and analysis unit containing a wireless communication receiver connected in series, connected by radio with a wireless data transmission unit installed onboard the vehicle, a primary data processing unit, a unit secondary data processing and decision support unit, made with the possibility of information support of emergency medical services and rescue.

All this makes this system cumbersome and expensive. Meanwhile, in most cases, the consumer does not need such complex systems. The main tasks for most car owners are the availability and receipt of timely and objective information about the circumstances of an accident.

In addition, none of the aforementioned known systems can solve such problems as traffic accidents with a stationary car. In most cases, it is extremely difficult for the car owner to restore the picture of such an accident.

The objective of this utility model is to eliminate these drawbacks by creating a compact and inexpensive system that combines the functions of a digital recorder of audio and video signals, as well as other signals coming from the sensors of the system with their subsequent processing, storage and delivery.

The problem is solved due to the fact that the monitoring system of information channels of mobile and stationary objects in real time with the possibility of recording the occurrence of emergency situations and fixing the state of the controlled parameters of the object, containing installed on the vehicle: shock sensors or standard sensors airbags, sound sensors, tensor or vibration sensors, volume sensors, brake sensors, as well as ADC, information board, additionally contains: archive of digital information, input minutes and output interfaces, a transmitter, a service interface consisting of the processor and chipset unit controls the external service processor CPU, a RAM, a RAM controller controlling recording on the basis of substitution in the RAM the information coming from the sensors and processed by the CPU. The digital information archive is configured to continuously record information about the state of an object for a given time interval with overwriting at its own memory addresses. The processor is configured to handle, in the event of an emergency in the form of a traffic accident, for information about the state of the object at memory addresses corresponding to its state with a distance of no more than 30 seconds, with the subsequent formation of an array of information corresponding to a specific time interval DT calculated by the formula :

DT = (T _events + N1) - (T _events -N2),

where T _events are the moment of a traffic accident, N1 and N2 are constant values of the cell number of the beginning and end of the interval, expressed in seconds, with 5≤N1≤30.5≤N2≤30.

At the same time, the digital information archive is made with the possibility of recording information for the DT period, its marking and storage until requested.

Also, the system may include sensors of the main and additional equipment of the car and means for transmitting operational video information in real time.

Figure 2 shows the organization of work of the time window block (BVI), where 26 is a sensor block consisting of sensors: shock or standard airbag sensors, accelerometer, sound sensors (electronic stethoscope), tensor or vibration sensors, volume sensors, brake sensors .

Principle of operation

The principle of operation of the system is reflected in figure 1.

When the system is activated (see Figure 1), a self-diagnosis of the health of the information processing unit and the integrity of the information sensor circuitry occurs.

Recording begins.

Signals from systems controlled in the car (A) are fed to the ADC (2), signals from car sensors (B) are sent to the input interface (3), signals from systems involved in generating the signal T of _event (B) are sent to the signal conditioning unit T _events (4). From the ADC and the signal generation unit T of the _{event, the} processed information is fed to the input interface (3), from where it is transmitted for processing by the central processor (5). Feedback and control of the input interface (3) is carried out through the service interface (6), which transmits control signals to the central processor (5), and from it they enter the input interface. The service interface consists of a processor and microcircuits.

After processing by the processor (5), the information goes to the RAM controller (7) and through it is recorded in the RAM (8) according to the replacement principle. In the event of an emergency, the process of saving an array of information about the state of the object’s parameters in the specified sector of the time interval is activated.

The information of interest to us for a given time interval is overwritten in the area of the digital information archive (9) and stored there until it is claimed and when it is read or removed by the user with subsequent reactivation of the system.

Diagnostic results are displayed on the information board (14).

Further use and archiving of information is carried out by additional technical means available to the user in accordance with the tasks.

After reactivation of the system, the monitoring process resumes. The number of recorded emergency situations, without further reactivation, is determined by the type and purpose of the controlled object, as well as the choice of the element base for building the system.

When the object enters standby mode, the system activates the security function with the possibility of audivisual open or hidden notification of the object operator. To solve the problem of organizing a “time window”, a RAM control circuit with the distribution of control signals is used.

The service interface (6) is connected to the security unit (10), the wireless output interface (11) is connected to the RAM and redistributes the information coming from the RAM to the terminal (19), the external control unit of the service processor (12) controls the operation of the service interface (6) , the data from the digital shooting unit (15) are sent to the video input interface (16), from where they go to the video RAM block (17), and from it they go to the video information archive (18), which also records sound information from sound sensors received in archive of video information (18) with RAM (8).

Information from car sensors is recorded in RAM in a strictly defined time interval by the method of "replacement". When a control signal appears, the RAM cell number is fixed at the moment of access and the formation (calculation) of the time interval (time window), according to predefined sizes according to the formula [1].

The formation of the recording sectors is as follows.

Tn = Tht-N1,

where Tn is the beginning of the recording sector (or time interval), Tt is the time of arrival of the signal of the _event T, N1 is the number of seconds taken, of the time of arrival of the signal of the _event T.

The end of the sector (or time interval) is calculated by the formula:

Tk = Tch + N2

Tk - the end of the recording sector (or time interval), Tch - time of arrival of the signal of the _event T, N2 - a fixed number of added seconds, from the time of arrival of the signal of the Event.

EXAMPLE 1:

an _event signal T came at the 25th second of the system operation.

Tn = 25-20 = 5 sec

Tk = 25 + 10 = 35 sec

Thus, from 5 to 35 seconds is our formed sector.

EXAMPLE 2:

the _event signal T came at the 5th second of the system operation.

Tn = 5-20 = -15 sec

Tk = 5 + 10 = 15 sec

Thus, from -15 to 15 seconds (since we have continuous recording), there is our formed sector.

At the end of the sector (window) recording, its contents are transferred to the RAM storage area (archive). By filling in this area, a feedback signal is generated, informing the processor about the end of this operation. The system continues to operate normally.

Information from the archive memory is identified and read through wireless technologies to the user terminal. This is possible both in automatic mode and upon request. A variant of its physical removal from the device is also possible. The circuitry and design feature of the system allows the possibility of connecting additional modules to realize the capabilities of the tachograph, trip computer, satellite navigation, etc. The set of sensors for the input interface is determined by the type of object and its functionality.

When used on stationary objects, the set of sensors supplying a useful signal changes.

The principle of generating a useful signal and reading information

To generate a useful signal - T _{event, the} sum of the operation of several sensors is taken. The main ones are shock sensors, shock-sensory or vibration, volumetric and noise (stethoscopic).

Based on the fact that accidents can be varied and, therefore, different sensors can be involved, an algorithm for making decisions about

event availability. In detail, this diagram is reflected in Figure 2, which shows the organization of work of the time window block (BWO).

The bottom line is that the block (26), consisting of a group of sensors, is involved in the formation of the useful signal:

1. Shock sensors or standard airbag sensors, accelerometer

2. Sound sensors (electronic stethoscope)

3. Tensor sensors or vibration

4. Volume sensors

5. Brake sensors

The remaining groups of sensors (interior, lighting, steering angle, video speed sensor or digital photos) are informational. Recording is done automatically without human intervention.

The participation of the object (TS) depending on the class of DPT, types of damage and the sequence of sensors (on the numbered scale of the aforementioned group) are shown in Table 1.

The indispensable presence of an operator for the operation of the system according to RF patent No. 2222830 significantly reduces the circle of consumers or leads to the complication of existing services. The presence of biometric sensors is unjustified due to the huge error in making decisions and the presence of at least a minimum medical education from the operator.

The function of the claimed system does not include monitoring compliance by the driver with the terms of the employment contract and traffic rules. The inventive system is responsible for the availability of objective information about the accident and ensuring the maximum establishment of the circumstances of the accident.

Since 80 percent of information about the world around a person is obtained through visual images, additional equipment was included in the system: video cameras for forming an analog or digital video sequence. As an alternative, wide-angle cameras with a resolution of 1.2 MP can be used, which continuously shoot at a given time interval.

The ability to obtain the desired sample of information appeared due to the application of the principle of a time window.

A similar analogue reflecting this principle can serve as the development of SONY Corporation in the latest models of digital video cameras. There, the essence of the process is as follows.

When you turn on the camcorder, automatic recording starts with a capacity of 5 seconds and if after these seconds the operator shoots, then this information is stored, and if not, it is overwritten with new information.

In the inventive system, the process is as follows: when the system is turned on, a full recording is performed during a time interval of up to 1 minute. For continuous recording of information, 60 cells are allocated and after the recording of the latter, information is replaced.

When a signal about an accident occurs, the processor accesses the memory addresses preceding the event and gives a command to generate a temporary file at a time interval calculated by the formula [1].

At the end of the formation of the useful signal, the command “record the last cell” is triggered and the next command “send sector to archive” records the archive.

The system goes into normal mode.

During the dubbing process, a second or third useful signal may occur. In this case, the conflicting node begins to work (duplication of information is turned on).

This situation is possible in group successive collisions.

Specifically, in the system, this is done by turning on the UK unit (13) in the case of the 2nd accident with a temporary difference of no more than that indicated in the formula [1], ie N1 and N2 (up to 30 seconds). UK is actually the second block of the BVI.

Only the insurance commissioner or representative of the insurance company, who, using wireless technologies, reads the contents of the archive, is allowed to read information. Information is presented in tabular form.

The novelty lies in the application of an integrated approach, using specialized software and hardware tools and methods, to the registration, processing and storage of telemetry data with the possibility of obtaining and further use by interested persons and services.

The technical result of the system lies in the possibility of fixing a wide range of different types of emergency situations, which allows it to improve the security and safety systems of various objects, as well as the resolution of insurance disputes.
