CZ31043U1 - A wireless monitoring and warning information system for emergency assistance - Google Patents

Description

Technical field

The technical solution relates to a wireless warning and information system that helps protect residents in case of emergencies.

BACKGROUND OF THE INVENTION

During and after World War II, warning systems were built on the platform of rotary sirens, first mechanical, then electric. These technical means continue to be used as terminal elements of emergency warnings, such as natural disasters, industrial accidents, chemical, biological, radiation and nuclear hazards, etc. In the 1970s and 1980s, the control infrastructure of these terminals was built through telecommunications lines, which were later replaced by analogue radio infrastructure. The infrastructure was built as one-way, ie it did not allow to determine the state of the terminal elements and their functionality, and transmits only basic commands such as the address of the terminal elements and the warning tone code. This infrastructure is still in use today and forms a backbone network for the control of end elements. Infrastructure modernization is done locally in a partial way. Rotary sirens are gradually being replaced by electronic sirens, which allow to reproduce verbal information using pressure acoustic transducers. The system has a number of technical limitations that prevent more effective protection of property, health and lives of residents. The responsibility for informing the population has been delegated to the mayors of towns and municipalities, who can use the existing means of warning or the so-called local information systems (MIS). MIS is a local information system with its own radio infrastructure and acoustic units located in a public area, which is also connected to a central warning system. At the same time, MIS can be supplemented with other detectors, light and text signals, etc. MIS systems have seen a significant increase in usage and various implementations, eg due to recurrent floods. They are installed for the needs of businesses, cities and municipalities. The detector and terminal element system is centrally controlled with the help of software (SW). The MIS infrastructure is secured against unauthorized entry and misuse. Systems are upgraded to increase user comfort, greater reliability and ease of use. Warning systems are also being developed in other developed European countries, such as Austria, Switzerland, Germany, etc., as well as in other countries where they cover risks arising from other expected natural disasters - typhoons, eruptions, earthquakes, tsunamis, etc. In a foreign country, a dedicated part of the network of mobile operators is commonly used outside the dedicated communication infrastructure. As other elements of alerts, social networks and other internet elements are also connected in various modifications abroad, which enable to monitor the impact of sent alerts.

The essence of the technical solution

The technical solution is representative of a new generation of wireless warning and information system, which helps protect people in case of emergencies.

It is a complex system in which data collection, automatic evaluation and subsequent warning of residents is integrated. The automation system collects information from the input monitoring elements and, using advanced algorithms, evaluates and generates alarm status reports. On the data collection side, it is the measurement of environmental variables such as current water level, soil saturation, precipitation, cloud movement, or the detection of hazardous substances and chemicals. Furthermore, image and location data are used as input data. Data from the measuring devices are sent via data via the system's independent radio network to the control station. Here, in the SW application of the system are evaluated, and in the case of a user-definable alarm situation, all responsible persons are notified. These persons can then use the system acoustically - wireless speakers with loudspeakers, home wireless receivers and sirens, evacuation radio, and / or visually-display panels, SMS, email and so warn endangered residents in a given location and give them other important information. The system is also adapted to be connected to the technical means of the components of the unified warning and notification system (JSVV).

The system includes a control unit connected to a control computer with a service application, remote SW clients for control, radio repeaters, if it is necessary to ensure radio coverage of a larger area, as well as two-way acoustic units with the possibility of adding units for measuring and monitoring levels, dangerous gases etc.

The technical solution is a wireless local information system and a system for alerting and informing residents in case of emergencies. Thanks to fast, reliable and targeted sending of voice and text messages it enables to save human lives, eliminate personal injury and reduce material damage caused by crisis events. The facility can be connected to a nationwide system of warning and informing the population. It integrates river level sensors and rain gauges, which then evaluates and provides support for decision making in emergency situations. Communication takes place via its own radio network or operator networks using modern elements of digital coding. A clear graphic application is used for operation.

The system can be used for small municipalities, towns and larger territorial units, or even in industrial areas where monitoring and subsequent transfer of information is needed.
