Each microcontroller 1, 9 is made in the form of a computer with a software configuration recorded in its own non-volatile memory.

The used elements and microcircuits (element base) are standard products; they are used in accordance with published catalogs. Microcontroller-computer on a single chip. Designed to control various electronic devices and implement the interaction between them under the control of the microprocessor core of the microcontroller in accordance with the program embedded in the microcontroller. In particular, microcontrollers 1, 9 preferably use commercially available microcontrollers type PIC16F, PIC18F, according to the Information Catalog catalog, St. Petersburg, GAMMA, 2002. Atmel microcircuits, 8-bit PIC16CXX microcontrollers manufactured by Microchip Technology and others. As transceivers 3, 14 of the RS-485 interface, it is advisable to use, for example, simplex chips ST485, MAX487. The small size of these transceivers makes them ideal for use in compact devices such as distributed systems with central and peripheral (s) devices. The advantages of these transceivers include improved protection against electrostatic discharge, fault tolerant circuit. The transceiver provides protection against electrostatic discharge up to ± 15 kV.

The components of the remote control module presented in the block diagram at the level of functional generalization relate to automatic devices for which the methods of synthesizing their structure by the meaningful description of the function (information about the functions described in the description) are known, i.e. they can be synthesized using well-known rules and methods by which an automatic device can be obtained according to the requirements for it.

As detectors (not shown in the drawings) are used, for example, a reader (from a card, from a key, etc.), a surface security detector (window), magnetic magnetic contact detectors, acoustic detectors, motion sensors, level sensors, sensors pressure sensors, fluid flow sensors, sensors of other physical parameters, reed switches, heat (fire) detectors, smoke (fire) detectors, combined fire and other detectors.

The module can be used, for example, in fire alarm systems and fire extinguishing systems, access control and management systems (turnstiles, locks, barriers, doors), control and management systems for engineering equipment (air conditioning and ventilation, water supply, electricity supply taking into account water consumption and / or electricity), lighting control systems, as well as in many other systems, including combined ones.

The module works as follows.

Functional units 9-24 in the BCU are powered by an alternating current mains voltage of 220 V, and if there is no voltage in the network, from a storage battery 13. The alternating mains voltage is reduced and converted (rectified) to a constant voltage of 20 V by a rectifier transformer 10 and stabilized at the desired value, the stabilizers 2. 11, 12, 20. In this case, from the stabilizer 11 voltage of 14 V, the battery 13 (battery) is recharged. The stabilizer 11 is equipped with a battery charge current limiter 13, the result of which is an automatically changeable battery charge voltage within 12 V-14 V, which also serves to power the remaining stabilizers 2, 12, 20. The mentioned voltage of 12 V is the minimum voltage at which the operation of external consuming sensors is possible (the case when the system works only from a battery 13 close to the discharge and there is no voltage of 220 V).

Microcontroller 1 in the BUI unit is responsible for interrogating the keyboard, electronic key, outputting information to the indicator, generating an audio signal, and organizing communication with the BCU unit.

The microcontroller 9 in the BCU block is responsible for collecting data from sensors, transmitting information to remote users, and organizing communication with the BUI unit.

Microcontrollers 1, 9 calculate the algorithm of their actions depending on the signals that came to them at the inputs and interact with all the equipment of the BUI and BKU.

Microcontrollers 1, 9 are spaced into two blocks for ease of assembly (installation) at the facility, with the possibility of spacing the BUI and BKI to a distance of up to 100 m, and providing the ability to connect several BKU to one BUI, as well as to ensure greater maintainability of the module by replacing the failed block, the aesthetics of the room (do not create a bulky single block).

The central unit of the BUI maintains a common database of the system and centrally manages all the equipment. Active and passive components (sensors, actuators and microcontrollers) are located in a single address space, which is a hardware-wire system for circulating material signals that carry information. Therefore, the number of connecting lines with the accepted distribution of equipment among the blocks is minimized, and the configuration of the system can change even during the operation of the structure.

The 5 V voltage of the respective stabilizers is powered by microcontrollers 1, 9 and other module elements. A voltage of 14 V is needed to charge the battery and to power the BUI unit. A voltage of 24 V is supplied to power the sensors connected to the inputs 18. Such an increased voltage of 24 V makes it possible to more reliably determine the response threshold of one or more sensors connected to one input. In addition, the increased supply voltage of these sensors, which differs from the supply voltage of other circuit elements, can reduce the number of false alarms of the system in the presence of electromagnetic interference, inevitable in industrial areas on the communication lines of peripheral units with the central unit.

In the standby mode of the module in the presence of voltage in the system, the microcontroller 1 periodically polls all the BKU blocks, and the latter - sensors (detectors). Sensors report the status of the object in the form of notifications. After switching on, the simplex module transceivers are in the “broadcast from the communication line” state. Keyboard 5 is used to enter a password, read the archive of events, enable / disable inputs, select an operation algorithm, set the clock and other system parameters. Transceivers 3, 14 of the RS485 interface exchange information between the BKU and BUI units. Simplex protocols organize time-sharing exchanges. The advantage of a simplex protocol lies, in particular, in its simplicity and reliability, and, therefore, in that the simplest interfaces can be used.

Information transmitted by the node 17 from the module, for example, the operation of sensors is transmitted to remote users - people or technical means of special services.

The microcontroller 9, depending on the signals of the sensors connected to its analog inputs 18, 20, recognizes the conditions of NORMAL, ATTENTION, ALARM, FAILURE, as well as the state of leakage. Relay 21 or 22 commutes power to an external device (not shown).

The electronic key on the BUI is used to identify the user who wants to gain access to the system management. You can also access by typing the code from the keyboard. An electronic key or card reader for controlling access to the premises is connected to one of the three digital inputs 19 of the BKU unit.

At the time of the action, for example, the application of an electronic key to a specific reader, a signal is generated at the input of the interface 6, which provides the exchange of information with the microcontroller 1 via input-output channels (logical inputs). Microcontroller 1 receives voltage-normalized (5 V) signals from the BCU, regardless of the presence and duration of interference, and the module as a whole can receive both the weakest useful signals against the background of strong interference at the same time or at least one powerful interference, and very Strong signals without overload and distortion. The microcontroller 9 finds in the memory 16 the key number and the number of the monitored zone, access to which is possible using this key. In accordance with the program available to him and the information of the permanent storage device 16 and the time monitoring device 15, the microcontroller 9 determines whether a person with this key has the right to access this zone at a given time, day of the week and month. The time control device 15 allows the microcontroller 9 to determine the validity of various signals in time - on the basis of the data obtained, compared with the data stored in the memory 16 about the set working time during the day and about calendar days off, holidays, etc.

In the event that the data available in the memory 16 and in the program of the microcontroller 9 indicate the legitimacy of access, the microcontroller 9 gives signals for the triggering of signaling devices, the microcontroller 9 of the control unit provides permissive signaling (notification) - the corresponding sound signal and ignition of the permit banner or blinking green LED. In this case, the transformer 10 and the stabilizers 2, 11, 12 provide coordination of the power transmitted along the signaling lines with the power consumption of the signaling means by converting the signals of microcontroller 1 with a voltage of 5 V into output signals of the required power.

In addition, the microcontroller 9 through the corresponding relays 21, 22 unlocks the door and / or releases the passage through the turnstile and / or opens the gateway and / or turns on the fire extinguishing means and / or opens / closes the shutters and / or turns on / off the fan or the air conditioner, etc. .d. To do this, the signals (voltage 5 V) of the microcontroller 9 in the control lines are converted into signals (voltage 12 V) at the control inputs of the relay, which in turn can close the power circuits of actuators having a voltage of the order of 220 V, 380 V, etc. in the same zone with sensors reduces the influence of interference.

In the event that the data available in the memory 16 and in the program of the microcontroller 9 do not confirm the legitimacy of access, the microcontroller 9 through the relay 21, 22 carries out an alarm — the transmission of a sharp sound signal, the ignition of a prohibitory banner or the flashing of the red LED and the ATTENTION / ALARM signal or FAULT on the security console.

In addition, the microcontroller 9 through the actuator relay control relays 21, 22, using actuators, blocks the door and / or locks the passage through the turnstile and / or closes the exit paths and / or turns on fire extinguishing means and / or opens / closes the shutters and / or turns on on / off fan or air conditioner.

At the same time, a record of the presence / absence of an employee in a certain area during working hours and, therefore, records of actually worked hours can be kept. Additionally, when an employee is in certain areas, it is possible to block / unlock the supply of water, electricity (for example, lighting), parts for assembly, and other materials. In necessary cases, a more complex information exchange of access codes is possible, for example, with repeated application of the same or a different key or a set of digital (letter) codes (password) on the keyboard, etc.

The appearance of smoke and an increase in temperature leads to the formation of the corresponding sensor signals coming through the control panel to the microcontroller 1. In accordance with the program, the microcontroller 9 through the corresponding relays 21, 22 and node 17 gives an alarm about the fire to all points from which people are to be evacuated, and to security premises, as well as company management. At the same time, the microcontroller 9, through the corresponding relays 21, 22, activates fire extinguishing devices - water supply mechanisms, foam, fire extinguishing powders, etc., and also isolates the burning room from other rooms by blocking or closing doors and windows, turning off the elevator, etc. funds. Similarly, a pressure sensor signal can be generated about a pressure drop below an acceptable level, indicating a rupture of the pipeline or tank.

Violation of the integrity of doors, door locks, windows glazing, etc. also leads to the formation of corresponding sensor signals coming through the control panel to the microcontroller 1. In accordance with the program, the microcontroller 9 through the corresponding relays 21, 22 and node 17 gives an alarm signal about the intruder in the security room, as well as the management of the enterprise. At the same time, the microcontroller 9, through the corresponding relays 21, 22, activates the protection devices - lowers the grates, closes the gateway, supplies voltage to the protective wire fences, turns off the lighting and water supply, closes the safes, etc., and also isolates the room into which it penetrated intruder, from other premises by blocking or closing doors and windows, turning off the elevator. The simplex mode of the transceiver is a mode in which information is transmitted between the central and peripheral unit (s) alternately under the control of the subscriber, i.e. the corresponding controller (1, 9), which prevents the spread of interference in the circuits, reduces the number of wired lines.

Thus, with the appropriate programming of microcontrollers 1, 9, it is possible to use actuators or signaling devices associated with one module when triggered (a sensor associated with another module.

Thanks to the implementation of microcontrollers 1, 9 with flexible configuration settings, individual processing of information from sensors is ensured, bringing it to a single software form and information is converted into individual commands in a single software form executed by peripheral equipment with the formation of a single address space of the central and peripheral blocks (blocks ), the coordination of the software of all equipment of the module is implemented when exchanging information between peripheral equipment and a mic rocker controllers 9 interacting with the operator-controlled keyboard 5 of microcontroller 1 only for setting and monitoring the complex. As a result of the adopted control and power supply scheme, peripheral and central units are protected from unauthorized interference, the module is fully automated, and mutual influence is reduced through the central unit of the ICU and the propagation of static and impulse noise, usually present at production facilities, between the peripheral units of the CCU.

Thus, a universal effective module with enhanced functionality has been created that provides reception and processing of several types of detectors (sensors) signals, as well as an expanded arsenal of modules.

At the same time, the functionality has been expanded for interacting with various types of detectors (sensors) distributed over long communication lines with various constructive design and controlled parameters, and for controlling various types of actuators, alarm elements, increased reliability of power supply, as well as increased reliability and accuracy of work in conditions static and impulse noise.
