Description

The utility model relates to the field of digital data processing using electrical devices and to the field of burglar alarms, namely to the central controllers of physical protection systems (including burglar alarm systems and access control and management systems) that implement all the basic algorithms of such systems can be used in perimeter control systems.

Integrated physical protection systems with a central controller are most widely used in creating integrated security systems for large and medium-sized facilities. The central controller provides a set of functions for access control, obtaining information about the operation of the alarm system and remote control of physical protection systems. Information about the state of all the above systems is transmitted to a computer on which special software is installed, designed for operational management and subsequent processing of data from physical protection systems.

The central controller ALGO-425 is known, which is used in the integrated system of physical protection of CJSC Algont (http://algont.kaluga.net/books/), to which interface controllers are connected: the ALGO-427 controller, which is a controller for collecting and processing information from security loops, and the ALGO-429 controller, designed to organize access control and management.

However, the ALGO-425 central controller does not have a backup function: when it fails, the entire group of ALGO-427 and ALGO-429 slave controllers loses a significant part of its functionality and is completely inaccessible to top-level software.

Closest to the claimed utility model is the central VNC controller, which is part of the FortNet integrated physical protection system (www.fortnet.ru), to which interface modules of the alarm system and access control system are connected. The central control VNC controller at the hardware level independently provides the functioning of an alarm system and an access control system. This controller is selected as a prototype of the claimed utility model.

The advantage of the prototype central controller is its ability to work on an Ethernet network. However, it does not provide a backup function, so if a VNC controller fails, the physical protection system capabilities are significantly reduced.

The objective of the utility model is to create a central controller of the physical protection system, which provides the full functionality of the physical protection system and has a backup function.

The problem is solved by creating a central controller of the physical protection system, which includes a control computer, peripheral equipment and interface modules, characterized in that it contains an industrial PC / 104 controller and an I / O port board, and the industrial PC / 104 controller has software software with a redundancy module, as well as the first and second RS232 ports, and the I / O port card is connected to the industrial PC / 104 controller via the ISA bus and has four independent galvanic unlinked RS485 ports, RS232 port and galvanically isolated RS232 port connected through a galvanic isolation device to the RS232 port, which is connected to the first RS232 port, while the RS485 ports are configured to connect peripheral devices of the physical protection system, and the second RS232 port is an industrial PC controller / 104 is configured to connect another central controller of the physical protection system for the purpose of redundancy, while one of the central controllers is active and the other is redundant, while m the backup software module is configured to simultaneously connect two controllers, the active and the backup, to the physical protection system, while only the active central controller is configured to control the operation of the physical protection system, and the RS232 galvanically isolated interface of the active central controller is configured to connect to a computer through one of the interface modules, the relay of which is made with the possibility of switching the RX and TX lines galvanically isolated Interface RS232, wherein the standby central controller is configured to supply commands to the switching lines RX and TX in the case when he decides to take control of physical protection system itself.

The central controller can have four independent RS485 ports.

For a better understanding of the claimed utility model the following is a detailed description with the corresponding drawings.

12 - redundant central controller.

Redundancy of the central controller is designed to ensure the operability of the physical protection system in case of failure of the main (active) central controller. A block diagram of a central controller of a physical protection system is shown in FIG. The central controller consists of a processor module made in the form of a single-board industrial controller of the PC / 104 format (1), and a board (2) of I / O ports, which has four independent RS485 ports (6) and two ports (7), (8), working in RS232 mode. All I / O ports except port 7 are galvanically isolated, including the RS232 port (8), galvanically isolated through the galvanic isolation device (9). The PC / 104 industrial controller (1) and the I / O port board (2) are connected to each other via the ISA bus (5), the connectors of which are installed both on the PC / 104 industrial controller (1) and on the port board (2) input-output Up to 32 security devices, RFID card readers, alarm modules, etc.) can be connected to each RS485 port (6) of the board (2) of the I / O ports. The galvanically isolated RS232 port (8) is used to connect the central controller to the computer.

Reservation of the central controller of the physical protection system is carried out according to the scheme shown in Fig.2. Both central controllers, active (11) and standby (12) are connected to the interface modules (10) in parallel to each other (preferably at different ends of the RS485 communication line). The active central controller 11 upon receipt of configuration commands, as well as when the state of the interface modules 10 changes, sends information to the backup central controller 12 through the second port RS232 (4) of the industrial controller PC / 104 (1). Accordingly, the backup central controller (12) receives this information through the second RS232 port (4) of its industrial PC / 104 controller (1). Thus, the backup central controller (12) is always in a hot standby state. Switching to the backup central controller (12) occurs in the following cases: by command from the control computer; in case of loss of communication with interface modules (10); when the active central controller (11) stops (freezes).

In the first two cases, control transfer is initiated by the active central controller (11), in the latter case, the backup central controller (12) decides on the need to take control.

In case of loss of communication with the control computer, the active central controller (11) checks the connection of the backup central controller (12) and, if available, transfers control to it, and connects the backup central controller (12) through the interface module (10) to the control computer. If it becomes necessary to transfer control to the backup central controller (12), the active central controller (11) stops the exchange with peripheral devices, completes the synchronization of the backup central controller (12) and then transfers control to it.

Although the above embodiment of the utility model has been set forth to illustrate the present utility model, it is clear to those skilled in the art that various modifications, additions and replacements are possible without departing from the scope and meaning of the present utility model disclosed in the attached utility model formula.
