The disadvantage of the device is also relatively narrow functionality.

In addition, there is a known system containing N processing devices, each of which contains a processing unit and two interface nodes with a trunk, N communication nodes, and the output of the b-th communication node (b = 1 ... N-1) is connected to the input (bl) -th communication node, and a microprocessor converter, the group of inputs and outputs of which is a group of inputs and outputs of the system for connecting to an external computer, while the information inputs and outputs of the first group of each processing device are connected to the information inputs and outputs of the corresponding communication node information The inputs and outputs of the second group of each processing device are the first group of inputs and outputs of the system, the second group of inputs and outputs of which are the input-output groups of processing units, the first and second groups of inputs of which are the group of inputs of the system, the output of each of the communication nodes is connected to the corresponding the input of the microprocessor converter, the output of which is connected to the input of the first communication node, the group of inputs and outputs of the microprocessor converter is the third group of inputs and outputs of the system, and the mic the processor converter contains two amplifiers, a microprocessor, a set of OR elements, an element and, an electrical signal to optical converter and a converter

The disadvantage of this system is also the relatively narrow functionality, since the known system is designed to automate the process of collecting information about controlled means, processing information and transmitting information to the consumer (maintenance personnel), but does not allow the control of the executive devices of the system.

The closest in technical essence to the proposed one is the Smart Home system, which contains a control unit consisting of a microprocessor, the first group of inputs and outputs of which is the first group of inputs and outputs of the control unit and the group of inputs and outputs of the system for connecting to an external computer, and the second the group of inputs and outputs - the second group of inputs and outputs of the control unit, as well as N groups of sensors and N groups of actuators, while the outputs of N groups of sensors and inputs of N groups of actuators are connected to the first th group of input-output control unit [System "smart house", the website http // www.realdom.ru /, 2005].

The disadvantage of the closest technical solution is the relatively narrow functionality, due to the fact that

all sensors and actuators are controlled from a single control unit, which significantly complicates the rapid replacement, development, modernization and reprogramming of sensors and actuators located, for example, in separate isolated and / or remote rooms.

The practice of designing and practical use of such systems shows that when servicing relatively large country houses and estates, it is more convenient to have separate units located in isolated and / or remote rooms that can perform local control functions of the corresponding sensors and actuators. This greatly simplifies the process of changing the programs of operation of these elements, the process of their repair, replacement and modernization, i.e. increases the maintainability of the system, especially during its development, as well as during the repair of individual rooms and the additional construction of individual buildings. In addition, it eliminates the need for physical control lines to connect all the sensors and actuators to the control unit. More economical is also the connection of their individual subgroups with one physical line to the control unit. This simplifies the system, increases its reliability, simplifies management, and also allows you to use a simpler design of the control unit.

The required technical result is the expansion of functionality, increasing the reliability and efficiency of management, as well as maintainability and efficiency.

This technical result is achieved by the fact that in a system containing a control unit consisting of a microprocessor, the first group of inputs and outputs of which is the first group of inputs and outputs of the control unit, and the second group of inputs and outputs is the second group of inputs and outputs of the control unit for connecting to external computer, as well as N groups of sensors and N groups of actuators, introduced

N processing and communication units and a power supply unit included in the control unit and whose output is the power supply output of the control unit and connected to power inputs of N processing and communication units, while the output group of each of the N control and communication units is connected to the group of inputs of the corresponding groups of actuators, the group of inputs is connected to the group of inputs of the corresponding groups of sensors, and the group of inputs and outputs is connected to the first group of inputs and outputs of the control unit.

The drawing shows the electrical structural diagram of the microprocessor information management system "Smart Home".

The microprocessor information management system "Smart Home" (below the "system") contains N processing and communication units 1-1 ... 1-N, as well as a control unit 2, consisting of a microprocessor 2-1, the first group of inputs and outputs of which is the first group of inputs and outputs of the control unit and the group of inputs and outputs of the system for connecting to an external computer 3.

In addition, the system contains N groups of 4-1 ... 4-N sensors, the group of outputs of each of which is connected to the group of inputs of the same unit 1-1 ... 1-N processing and communication, as well as N groups of actuators 5- 1 ... 5-N, the group of inputs of each of which is connected to the group of outputs of the same block 1-1 ... 1-N processing and communication.

Additionally, the control unit 2 includes a power unit 2-2, the output of which is the power output of the control unit 2 and is connected to the power inputs of N processing and communication units 1-1 ... 1-N.

Moreover, the second group of inputs and outputs of the microprocessor 2-1 is the second group of inputs and outputs of the control unit 2 and is connected to the inputs and outputs of N processing and communication units 1-1 ... 1-N.

ATMega128-16AI microprocessor can be used as microprocessor 2-1 of control unit 2, stabilized power supply unit BPS 12-2 12V 2A as power supply unit 2-2, as blocks

1-1 ... 1-N processing and communication - microprocessor type ATMega81-8AI, as sensors of groups 4-1 ... 4-N - any sensors with relay outputs, as actuators - relays, electromagnetic valves, pneumatic actuators , dimmers, electronic IR control devices, etc.

The microprocessor information management system "Smart Home" works as follows.

The system provides a mechanism for centralized control and intelligent control in residential, office or public buildings, modern service and coordinated work of all autonomous systems included in the infrastructure of an apartment, house or village, monitors and controls engineering systems, multi-level warning in case of an accident, and also records consumption resources.

The system allows, within the framework of the habitat, to set and control the parameters of this environment (light, air temperature, humidity, sound, etc.), create individual work scenarios. In addition, the system allows monitoring and control of engineering systems (lighting, climate, video surveillance, heating, gas and water supply, ventilation, security ...). At the same time, it is possible to control from a single panel (control unit) all elements of the infrastructure in the house (audio-video equipment, sauna, household appliances, blinds, lights ...), to access information on the state of all elements, life support of the house (while inside or remotely), as well as notification in case of emergency, performance of service functions (logging of events, sound greetings, imitation of presence, imitation of the presence of animals ...). It is possible to include a personal computer, PALM, or other means in the system for visual communication of the system with the user. Control and

system management can be carried out remotely using mobile communications and the Internet

Power supply unit 2-2 is a source of secondary power supply and provides a stabilized 12V voltage level for powering all energy-consuming system elements. The microprocessor converter 2-2 of the control unit 2 contains all the logic of the system.

The group of 4-1 ... 4-N sensors includes sensors for temperature, light, smoke, movement, etc.

Group 5-1 ... 5-N actuators include switches for lighting fixtures, air conditioners, home theaters, tape recorders, as well as dimmers, relays, solenoid valves, control interfaces (push buttons, remote controls, touch panels, web / wap interface , LCD keypads), etc.

Blocks 1-1 ... 1-N of processing and communication receive signals from sensors - in the form of discrete signals of logical zeros and units "closed-open" ("worked - did not work") from the corresponding sensors of groups 4-1 ... 4-N - temperature, light, resistance readings, etc.

The processing and communication units 1-1 ... 1-N convert these signals into packets (internal network data), coordinate sending data with the control unit 2, and sends them over the internal network (the connections between the system units) to the control unit 2, which is the main system control unit. The microprocessor 2-1 included in its composition (the central processor of the system) processes the data according to a given program determined by the required system control algorithm, applies the required connections and dependencies, and provides a result and a list of actions that again goes to blocks 1-1 via the internal network .. .1-N processing and communications in which they are converted into control signals by actuators of the relevant groups 5-1 ... 5-N

actuators - relay operation, smooth voltage change, etc.

In addition, the processing and communication units 1-1 ... 1-N constantly “communicate” with the control unit 2, informing it of the necessary parameters of some sensors after a certain period of time, and if there is no signal from the corresponding sensor, then the control unit 2 makes a decision about an emergency and acts according to the corresponding scenario, forming, for example. Signal of emergency shutdown (inclusion) of the corresponding devices.

The internal network resembles a local area network, where the data goes in the form of packets, which indicate which point it should receive, and what actions should be performed.

Monitoring and management of engineering infrastructure elements is as follows. Information from sensors (water leakage, gas leakage, humidity, temperature, security, fire, etc.) comes through the communication processing units 1-1 ... 1-N to the microprocessor 2-1 of the control unit 2 and, in the case of the output of controlled parameters beyond (max-min), or when a sensor or timer is triggered, the control unit 2 processes the received information, generates a control signal according to a predetermined algorithm defined by the customer, and transmits it to the actuator (water valve in case of a leak, engine when closing shutters or opening the gate, siren - in case of penetration; switch - to control the light, etc.). All occurring events are recorded in the protocol, which can be read at any time on the computer screen 3. In addition, in emergency (emergency) situations, the system will notify by telephone line and voice announce the reason for the call or send an alarm SMS message via mobile communication. Notification is carried out by several numbers in each case and does not end until it reaches you.

The system always works, regardless of whether the owner is at home or not, it only goes from one mode to another. For example, when using a power supply unit 2-2 with a backup battery and turning off the power, the system switches to battery power and reports this by telephone line.

The system provides service functions - greeting the system itself, the ability to record and read voice messages to family members (voicemail), voice alarm - it will wake you up or remind you of something important. In addition, in your absence, it will scare away random thieves by playing a dog barking when you press the input bell, it will simulate your presence by lighting a light and turning on music as someone approaches your apartment.

The system can additionally monitor and control existing systems in an apartment, house or cottage.

In the system, the main device is the control unit 2, which is the master device of the system that stores all the algorithms, logical connections, and the configuration of this system. Its compactness allows it to be installed in a place hidden and inaccessible to third parties, thus allowing, even if the control panels and other openly installed devices are damaged, to keep the system working, increasing home safety.

The expansion of the system does not require invasion of the already mounted part of it, which avoids laying additional cable in the previously repaired part of the apartment, house or building.

Thus, by improving the known device, the required technical result is achieved, which consists in expanding the functionality, increasing the reliability and efficiency of management, as well as maintainability and efficiency.
