Description

Field of technology

This utility model refers to a radio system for centralized monitoring of security systems, which will find application in the field of security and protection, and in particular in the protection of protected sites from unauthorized intrusion.

BACKGROUND OF THE INVENTION

Security systems are designed and built in different types of sites in order to protect and limit unauthorized access to property, valuables, information, access control in buildings, facilities or the territory of a site and others.

The alarm-security and fire-alarm systems through the detectors installed in the sites produce and emit an alarm signal for the occurrence of a certain event. After processing, the registered signals are forwarded to a monitoring center, which assesses the nature of the signal and takes appropriate action.

In practice, radio channel security systems are known, which are characterized by simplicity and speed of installation; with the possibility for protection of any type of sites within the established radio network; with the possibility for operative change of the system configuration; with the possibility of building regional monitoring centers and their unification into a single national monitoring system.

In recent years, other wireless technologies for alarm transmission, based mainly on GSM and GPRS systems, built by public mobile operators, have become widespread. They do not require the creation of their own / private radio network and obtaining a license to use certain radio channels, but require reliable coverage from the network of the GSM operator. At the same time, these systems have a low degree of protection, as their signals can be very easily jammed. GSM silencers are known, which can jam mobile phones and various radio devices that operate on cellular communication frequencies of GSM 900/1800 MHz, 3G 2100 MHz, 4G and new networks of the latest generation 5G.

The most efficient and cost-effective are the systems for centralized security of the sites. The essence of the organization of the centralized security consists in the automatic transmission of the information from the technical means of security, installed in the territorially remote sites, to a single monitoring center.

Technical essence of the utility model

The task of the utility model is to create a radio system for centralized monitoring of security systems, which will provide both automatic transmission of information from technical means of security to a unified system for monitoring, analysis and evaluation of received signals and feedback from the monitoring system. to the technical means of protection, and signaling of the forces for quick reaction upon receipt of alarm signals.

The problem was solved by creating a radio system for centralized monitoring of security systems, which includes ten channel encoder-decoders receivers for radio network, equipped with antenna amplifiers connected in one direction via the Internet with a monitoring and control system. The monitoring and control system is connected via the Internet to a single-channel radio signal encoder-decoder equipped with another antenna amplifier. The single-channel radio signal encoder-decoder is unidirectionally connected to object multi-channel alarm transmitters.

The advantage of the created radio system is that it provides centralized monitoring of security systems, higher accuracy and precision of the information from the signals received from the objects, through radio communication with minimal energy consumption.

The present utility model is illustrated in the attached figure 1, which is a schematic diagram of a radio system for centralized monitoring of security systems, according to the utility model.

Examples of implementation of the utility model

The created radio system for centralized monitoring of security systems, shown in Figure 1, includes ten channel encoder-decoders receivers for radio network 1.1, 1.2 ... lk, equipped with antenna amplifiers 2.1, 2.2 ... 2.k, connected in one direction via the Internet with monitoring and control system 4. The monitoring and control system 4 is connected via the Internet to a single-channel radio signal encoder-decoder 5 equipped with another antenna amplifier 6. The single-channel radio signal encoder-decoder 5 is unidirectionally connected to object multi-channel alarm transmitters 3.1, 3.2. .. Z.p.

The multi-channel alarm transmitters 3.1, 3.2 ... Zp can operate in the range from 135MHz to 175MHz or from 10 MHz to 470 MHz, with up to 16 programmable frequencies, and have developed their own protocol for information exchange. This allows not to duplicate the sent signals and to wait for feedback on the reception of the signal. This significantly increases the number of alarm transmitters 3.1, 3.2 ... Zp, using a certain frequency channel simultaneously. The multi-channel alarm transmitters 3.1,3.2 ... Zp have a software filter for the signals coming through the digital inputs, as well as a programmable option for retransmission of the signals from the unrecovered zone. In addition, the alarm transmitters 3.1, 3.2 ... Zp have the ability to divide the transmitter into two independent groups and have protection against peak voltages in the power supply.

The ten-channel encoder-decoders receivers for radio network 1.1, 1.2 ... l.k decode the incoming information on each of the ten radio inputs, measuring the level of the incoming radio signals and repeating the received messages after a certain period of time, which period can be programmed. In addition, the channel encoder-decoders receivers for radio network 1.1, 1.2 ... 1 .k have an LED indication for receiving a valid packet of signals for each of the ten inputs, and after verification of the received packets, they are transmitted on a serial channel and / or via a built-in LAN or GPRS module to the monitoring and control system 4.

To improve the reception of the radio signals emitted by the site multi-channel alarm transmitters 3.1, 3.2 ... Z.p, each encoder-decoder for radio network 1.1, 1.2 ... lk is connected to a specially developed antenna amplifier 2.1, 2.2 ... 2.k of the LNA type.

The monitoring and control system 4 is a computer system that receives the signals sent by the multi-channel alarm transmitters 3.1, 3.2 ... Zp and through specially developed software visualizes the status of the objects on a monitor and an electronic map. In addition, alarm events are stored in the monitoring and control system 4; the times of the received alarm event and the arrival and / or reaction of the operator on duty and the mobile security team shall be recorded; priority levels are provided for access to the stored information and its storage for a certain period of time and constant automatic control of the connection is carried out. The monitoring and control system 4 sends through the single-channel radio signal encoder-decoder 5 feedback to the multi-channel alarm transmitters 3.1,3.2 ... 3 .n, and can also disconnect a certain transmitter from them.

The created radio system for centralized monitoring of security systems is used as follows.

Upon receipt of an alarm signal from the alarm system of a given site, the multi-channel alarm transmitters 3.1, 3.2 ... Zp transmit it on a randomly selected, pre-programmed, currently available radio channel. The signal is picked up by the nearest ten channel encoder-decoders receivers 1.1, 1.2 ... l.k also on a random channel and by a random receiver. The receivers 1.1, 1.2 ... lk process the signals and through the built-in GPRS / LAN module forward them to the monitoring and control system 4. The multi-channel alarm transmitters 3.1,3.2 ... Zp transmit the signal packets until they receive feedback from the system for monitoring 4 by the single-channel radio signal encoder-decoder 5 that the signals are received.

Multi-channel alarm transmitters 3.1,3.2 ... Zp in addition to alarm signals can transmit
