Description

The utility model is intended for centralized radio surveillance of real estate objects, apartments of citizens, offices, warehouses, garages, etc., and for fire monitoring in units of the Ministry of Emergencies.

The well-known “RAD AND THE CHANNEL ALARM SYSTEM FOR CENTRALIZED SECURITY OF MOTOR VEHICLES, REAL ESTATE, PEOPLE AND ANIMALS” RU 2182088 [1], which contains blocks of fixed security devices connected to guarded devices antennas for communication over the air, a data collection and processing center having a remote terminal device with an antenna of a remote terminal device for communication over p the radio ether and the central monitoring console, which includes the information input adapter board connected to each other and connected to the remote terminal device, the radio communication is made in the form of a microcellular data network with base stations and transponders.

A disadvantage of the known device is the high complexity and cost of installation associated with the installation and configuration of microcellular stations.

Closest to the claimed technical solution is the "RADIO-CHANNEL SECURITY SYSTEM WITH PATROL VEHICLES" RU 2238589 [2], which contains stationary security alarm installations, each of which contains a stationary object terminal device and a detector unit, the outputs of which are connected to the inputs of the object terminal device using radio channels with transmitters and receivers, stationary alarm installations are placed along the guarded object at intervals of about providing relaying along the chain of messages from the stationary object terminal devices of the detector units that are part of the repeaters.

The device [2] has a simpler installation and relatively low cost, since there is no need for mandatory installation of a microcellular communication network.

A disadvantage of the known design is the difficulty of alerting people in the coverage area of the radio channel system.

The technical result of the proposed utility model is the ability to alert people in the vicinity of the security system and increase the reliability of data transmission on the operation of the end device.

The technical result is achieved by the fact that at least one object terminal device that is part of the system is connected by a radio channel to at least two adjacent devices.

With the proposed construction of the block, the neighboring block and the entire chain goes into an alarm state when one block is triggered, which alerts people located near (at a distance of visibility and audibility) of the installed fire alarm system.

The proposed implementation of the system improves the reliability of data transmission on the operation of the end device, since the signal is transmitted via two independent radio channels and the signal can "bypass" the faulty unit.

The structure of the object terminal device may include a fire detector, a sound annunciator, a flashing light, a light annunciator, an uninterruptible power supply unit with a switch. The specified composition of the object end device allows for the notification using known blocks.

Each unit may include a receiver for 8 RR-701 R transmitters and a stationary 4-zone transmitter with built-in RR-701TS4 signaling loops. The listed receiver and transmitter have all the characteristics suitable for constructing the proposed systems.

The system may additionally include car pager transmitters. The use of automotive pager transmitters will expand the functionality of the system by manually bringing it into alert mode.

An example of a stationary installation of a burglar alarm using PP1-4 is shown in figure 1, where:

1 - fire detector;

2 - sound annunciator;

3 - flashing light;

4 - light annunciator;

5 - uninterruptible power supply unit;

6 - switch;

7 - radio receiver;

8 - radio transmitting device.

The system operation diagram is shown in Fig. 2 (A, B), where part A shows signal transmission in a ring, part B shows signal transmission with signal duplication from block 4 located in the center to neighboring blocks, where:

9 - block with a triggered alarm;

10 - blocks adjacent to the triggered block;

11 - single radio channels;

12 - dual radio channels.

The device operates as follows: When the fire detector 1 fires, the buzzer 2 and the flashing light 3 are turned on. The signal is also sent to the radio transmitting device 8. When the alarm is received by the radio receiving device 7, the detector 1 also goes into alarm mode and turns on the buzzer 2, the flashing light 3 and transmits a signal to the radio transmitting device 7. The uninterruptible power supply unit 5 provides power to the stationary installation. The switch 6 provides the necessary switching when turning on and off the device. Light annunciator 4 signals that the unit is on.

When compiling the blocks in the circuit shown in Fig. 2 (option A), the block with the triggered alarm 9 transmits a radio signal to neighboring blocks 10 via single radio channels 11, bringing the entire system to a warning state, which allows you to quickly notify individuals whose hearing organs and vision is affected by signals from light and sound annunciators.

When installing the radio channels according to Clause 2 of Formula (option B), the signal from the triggered device 9 is transmitted to a minimum of two neighboring devices 10 via dual radio channels 12, which further increases the speed of notification of the population in the system coverage area and increases the reliability of the proposed system.

Industrial application. The utility model can be successfully applied for the production of wireless alarm and warning systems.
