Description

The utility model relates to devices for recording and indicating impacts on water vehicles for alarm systems.

A device for recording and indicating the operation of a vehicle is known from the prior art, containing sensors that make it possible to obtain data regarding the operation of the vehicle (see US 20160094964 A1, publ. 03/31/2016). The known device contains a processor that receives data, including from an accelerometer, a built-in event recording memory, and a data transfer interface. The disadvantage of the known device is the impossibility of its use at water transport facilities, since it does not contain sensors that take into account the specifics of the aquatic environment.

Also known from the prior art is a device for detecting and recording mechanical events for water transport, containing an interconnected processor, power supply, communication unit, accelerometer, gyroscope, memory unit (see WO 2007037749 A2, pub. 04/05/2007). This device is accepted as a prototype. At the same time, the prototype has the disadvantage of an insufficiently comprehensive analysis of the resulting impact impacts on water transport.

The purpose of a utility model is to eliminate the shortcomings of the existing level of technology.

When performing a task with a utility model, a technical result is achieved, which consists in expanding the set of recorded parameters characterizing impact impacts on water transport.

The task is completed, and the technical result is achieved by a module for recording shock impacts on water transport, containing an interconnected processor, power supply, sensors and a communication interface located in a single housing, and, according to the useful model, a three-axis accelerometer, a three-axis gyroscope with a temperature sensor and a three-axis magnetometer are used as sensors, while the processor is configured to receive data from the listed sensors and a time counter located in the same housing.

The processor is configured to write data to external RAM built into the case.

The processor is configured to provide feedback to the communication interface.

The essence of the utility model is further illustrated by a non-limiting example, reflected in the accompanying figures 1-2, where FIG. 1 - diagram of the module for recording impacts on water transport, Fig. 2 is an example of a general view of a module for recording impact impacts on water transport.

Individual positions in Fig. 1 indicate the following elements: 1 - single module housing, 2 - processor, 3 - power supply, 4 - wired communication interface, 5 - three-axis accelerometer, 6 - three-axis gyroscope with temperature sensor, 7 - three-axis magnetometer, 8 - time counter, 9 - wireless communication interface.

The module for recording shock impacts on water transport contains an interconnected processor 2, power supply 3, sensors and a communication interface 4 located in a single housing 1. In this case, a three-axis accelerometer 5, a three-axis gyroscope with a temperature sensor 6 and a three-axis magnetometer 7 are used as sensors. The processor 2 is designed with the ability to receive data from the listed sensors and time counter 8, located in the same housing 1.

Processor 2 is configured to write data to external RAM built into housing 1.

Processor 2 is configured to provide feedback to communication interface 4.

The utility model is intended for water transport (river and sea class vessels).

The utility model is intended for recording collisions of swimming equipment with each other and with other objects, assessing the degree of criticality of the recorded shocks and vibrations. Based on an assessment of the degree of criticality of impact impacts, as well as other related information, the software of the intelligent ship universal terminal makes a decision on the need to promptly notify emergency services.

A set of navigation and communication equipment (intelligent ship universal terminal), which is equipped with river and sea class vessels, receives information from the impact registration module.

The module for recording impacts on water transport assesses the degree of criticality of the current situation, incl. shock impacts received by the ship relative to the current situation. Based on an assessment of the severity of the situation, the terminal makes a decision to call emergency services.

A three-axis accelerometer (vibration acceleration meter), a three-axis gyroscope with a built-in temperature sensor, a three-axis magnetometer is an impact recording module (IRM).

After turning on the power, the MRV goes into an endless mode of recording vibration accelerations, rotation speeds, magnetic field strength along three axes and temperature and constantly determines:

1) moment, direction and energy of impact;

2) roll and trim angles.

The MRUV transmits this information to the processor node and external RAM, in which an operating system with a software module for monitoring shocks and vibrations is installed. The shock and vibration monitoring software module receives data from the MRUV, calculates the degree of criticality of the recorded shocks and vibrations, and, taking into account information from the satellite navigation system (GNSS) and other sources of heterogeneous information, if the criticality level of the event is exceeded, initiates a procedure for alerting emergency services. communication channels, as well as alerting the navigator using alarms (detectors, indicators - buzzer, siren, beacon, etc.).

All recorded events are recorded in the measurement log (database) indicating the time according to the clock of the proposed module for recording impact impacts on water transport (time counter).

The module for recording impacts on water transport carries out a statistical analysis of the recorded data, and also evaluates the level of impacts. As a result of the analysis, quantitative characteristics and qualitative indicators of the current state of the object and the environment are formed. This data, in accordance with the developed protocol, is sent to the intelligent ship's universal terminal (on request or in streaming mode).

The module for recording impacts on water transport has two communication interfaces:

- main RS-232 (wired),

- additional WiFi (wireless).

The wired interface is designed to transmit data between the impact recording module and the intelligent ship's universal terminal. The proposed module is not configured via a wired interface.

The wireless interface is used to configure the module and update the firmware.

The impact recording module has two LED indicators on its body:

- green (continuous light) - presence/absence of power supply;

- yellow (blinking) - designation of data transfer moments.

Thanks to the design features of the utility model:

1. For the first time, the specifics of determining the fact of impact and calculating impact parameters specifically for water transport were taken into account:

- the special nature of the resulting vibrations after impacts is taken into account,

- the duration of the impact aftereffect for ships can be several times greater than the duration of the impact for cars due to the low viscosity of the aqueous medium.

2. A complex criterion for assessing the criticality of an impact has been introduced based on the impact energy, the angles of heel and trim at the moment of impact and their history, the direction and speed of the vessel, an assessment of the strength and direction of the impact and its consequences.

3. Signal analysis was used not only in the time domain, but also in the frequency domain to highlight dangerous impacts against the background of the current situation.

4. When determining the degree of criticality of impacts, data on the orientation of the object in space is also used.

5. When determining the degree of criticality of impacts, the history of impacts and their statistical indicators are used.

6. When making a decision to call emergency services, dynamically adjustable thresholds are used (adaptive system response has been introduced depending on external conditions, the unknown frequency of occurrence of events and the weight and size characteristics of the vessel).

Thus, the useful model achieves a technical result consisting in expanding the set of recorded parameters characterizing impact impacts on water transport.

A search through publicly available sources of information showed that the entire set of features of the proposed utility model is not known from the prior art, and therefore it meets the “novelty” patentability condition.

The declared utility model consists of materials and elements standard for this field of technology, interconnected in a certain way, that is, it can be used in industry, and therefore meets the patentability condition of “industrial applicability”.

It should be understood that after a specialist considers the given description with an example of the implementation of the proposed utility model, other changes, modifications and options for implementing the utility model will become obvious to him. Thus, all such changes, modifications and implementation options, as well as other areas of application that do not differ from the essence of this utility model, should be considered protected by this utility model within the scope of the attached formula.
