For example, detectors of input control 21 via input terminal 1120 and output terminal 1131 are connected respectively to the interface periphery of the input control 112 and to the power supply unit 35; security detectors, motion detectors, seismic, vibration, magnetic, acoustic, optical and more detectors. 22 through input terminal 1110 and output terminal 1132 respectively to interface periphery 40 security installation 111 and to power supply unit 113, fire detectors 23 via input terminal 1100 and output terminal 1133 respectively to interface periphery fire alarm system 110 and to power supply unit 113, mnemonic 113 circuit board 24 through output terminal 1101 to interface periphery fire alarm installation 110, PC 25 and modem 26 respectively via input-output terminals 1020, 1021 to PC interface and modem 102, actuators 27 such as bush and light teller 271, fire extinguishing systems 272, television surveillance 273, electromagnetic locks 274, elevator controls 275, fire control unloading automation 276, alarming via a non-switchable telephone pair 277 and other actuators 278 via input-output 1151 through an input-output 1151 connected to the control unit and peripheral control unit of actuators 115, information screen 28 via output terminal 1071 and keyboard 29 via input-output terminal 1070 are connected to the interface peripheral fill Mechanisms 107 and Readers 30 via Inlet Valve 1090 — With Reader Interface 109.

The operation of the system is as follows.

Each control device 1, 2, ... n-1, η continuously monitors the information received from the connected peripheral detectors, input control 21, security detectors 22, fire detectors 23, readers 30, as well as information from actuators 27, respectively. through interface periphery input 112, interface periphery security installation 111, interface periphery fire alarm system 110, interface readers 109, as well as through block control and control peripherals actuators 115 and interconnected with it interface peripherals actuators 107.

The information received from the periphery interface input control 112, from the periphery interface security installation 111 and from the periphery interface fire alarm system 110 enters the analog-to-digital converter 108, is converted to digital form and together with the information received from the periphery interface 107 and actuators 107 the reader interface 109 is transmitted to the microprocessor 101 for processing and analysis.

The microprocessor operation algorithm 101 continuously monitors, in real time, the state change of each line connected to the interface periphery input control 112, interface periphery security installation 111, interface periphery fire alarm system 110, interface periphery actuators 107 and interface reading, Controlling the periphery of the security system by the following parameters:

-normal condition

-alarm state -intervention-broken line -intervention-short circuit in line.

The microprocessor 101 analyzes the information received from the respective interfaces from the periphery of the system, compares it with the pre-programmed state of each element of the periphery and, if there are no deviations, the starting point can be assumed that the security system is in normal mode.

If for some reason there is a change in the pre-programmed state of any element of the periphery detectors input control 21, periphery detectors security 22, periphery fire detectors 23, periphery actuators 27 and periphery readers 30, this change is perceived by the corresponding interface 112 periphery , interface security installation 111 and interface periphery fire alarm installation 110, is converted to analog-to-digital converter 108 and together with the information received from and The interface periphery actuators 107 and the analog-to-digital converter 108 are transmitted to the microprocessor 101, which in turn includes an algorithm for processing the situation. The microprocessor 101 processes the priority information according to which part of the periphery the signal for change in the state-fire alarm, security or incoming control is received, evaluates the received information and makes a decision to control the actuators 27.

The actuators 27 are controlled by a peripheral actuator control unit 115, which contains the corresponding outputs provided with feedback circuits, thereby monitoring the correct operation of the actuators. This information through the interface peripherals actuators 107 flows back to the microprocessor 101 for comparison, evaluation and, if necessary, for a new execution command.

The logged state change of the system from an arbitrary control device, e.g., n, a decision and the corresponding execution command, as well as the execution itself, is written to memory 106 and sent to block 104 for serial asynchronous communication, which transmits it to the local communication interface with a short circuit isolator 100, which, at the command of the microprocessor 101, transmits it to all control devices No. 1,2, ... n-1, n, connected in the local communication network of the system.

After the PC operator 25 takes adequate action to respond to the particular situation, the PC 25 sends a confirmation to the central control unit 1 that the information transmitted by it is received and registered in the computer 25 memory. local communication with a short circuit isolator 100 sends a command to the control device n that the information transmitted by it is processed and recorded.

In each control device 1,2, ... n1, η there is a built-in serial synchronous communication unit 105 that serves as a link between the microprocessor 101 and the local units embedded therein necessary to synchronize and protect its operation.

The power supply unit 113 and the redundant power supply unit 114 provide a DC voltage for each control device 1,2, ... n-1, n, as well as for a part of the devices connected as peripherals to the respective control device, even in the event of a power supply failure. .

The microprocessor 101 continuously monitors the normal operation of the power supply unit 113 and the redundant power supply unit 114.

Reader Interface 109 serves to interface with access control peripherals and, depending on security requirements, the following types of reader 30 may be used as peripherals: Wiegand efect; Magnetic tape; electrostatic; biometric (iris, hand geometry); infrared; radio signal and others.

The periphery interface executing mechanisms 107 serves to control the remote keyboard 29 and the information screen 28. The keyboard 29 is used to enter commands to control devices 1,2, ... n-1, n, and the information screen 28 shows current information about the one of the control devices 1,2, ... η-1, η and the periphery connected to its inputs.

The keyboard 29 and the information screen 28 can operate in parallel with the PC 25 and are not a mandatory part of the security system. If necessary, the security system can be configured through a PC 25 and then only controlled by the keypad 29.

After the control devices are first connected to the local communications network of the security system, the operator, through the PC 25, configures the entire system.

Each microprocessor 101 is self-configured depending on the presence of interface peripherals actuators 107, interface readers 109, interface peripherals fire alarm system 110, interface peripherals security installation 111 and interface peripherals control 112, taking into account their number and purpose. The self-test unit 103 of the system continuously monitors the performance of each control device as a whole.

Real-time system self-test unit 103 information is currently displayed on an information screen 28 and on a computer monitor 25.

The information from the periphery interface of the fire alarm installation 110 is displayed in parallel on the mapping board 24.

The security system maintains a complete archive of all logged events, the information being stored in the memory 106 of the respective control device and in the hard disk of the personal computer 25. If necessary, the system allows archiving reports, the information can be retrieved at a certain predefined a sign.
