The technical problem also lies in the need to expand the arsenal of building control systems for the Smart Home building by combining the controller’s wired and wireless communication channels with sensors and actuators in one system.

Disclosure of the invention

The technical result consists in combining in one system a radio path with wired technologies by creating a so-called bridge between them, performing the function of an integrator. Thanks to this, the specialist, having the skills to work in wired systems, without the need for additional training, will immediately be able to implement projects of any level of complexity using both wired and wireless technologies. This is achieved by applying deep data and protocol conversion from one to another inside the system by creating a “smart link” between two protocols (Modbus and ZigBee). To this end, the system implemented an economical, energy-efficient, noise-protected high-frequency radio signal in urban areas (2.4 GHz); implemented the combination of the well-known wired Modbus protocol and the latest ZigBee wireless protocol in modern realities, due to the lack of specialists in the "wireless" field and their presence in the "wired"; a universal method has been implemented for controlling all types of home appliances, including all types of audio, video equipment, home cinemas, air conditioners, humidifiers, dehumidifiers, curtains, gates, shutters, etc., controlled via the IR channel. The technical result also lies in the implementation of this purpose.

The technical result is achieved in that the intelligent hybrid modular building management system (smart home) contains a controller configured to work in a wired RS-485 network using the Modbus protocol and in a wireless network using the ZigBee protocol, connected to the controller using a wired RS network -485 executive wire modules designed to connect sensors and actuators to the controller, and wireless executive modules connected to the controller using using a wireless network using the ZigBee protocol and intended for connecting sensors and actuators to the controller, while the mentioned controller contains an ARM processor, a real-time clock, a non-volatile real-time calendar, an RS-485 port, an RS-232 port, a GSM modem, USB port, Ethernet port, analog inputs 0-10V, digital inputs with counting mode, 1 Wire port for connecting I-Button keys and temperature sensor LD2-TS, relay outputs, ZigBee modem, and the aforementioned wired and wireless modules include controlled relay modules in two versions - miniature design for installation in cups of sockets for switches and sockets, as well as for installation on a DIN rail, controlled dimming modules, infrared communication modules, modules with digital inputs, which are made in miniature cases, expansion modules for connecting sensors with a universal number of control inputs and outputs located in DIN-cases, as well as motion and light sensors.

The new features of the claimed technical solution are that the system contains executive wireless modules connected to the controller using a wireless network using the ZigBee protocol, designed to connect sensors and actuators to the controller, as well as in the aforementioned version of the controller and executive modules.

The implementation of the invention

The basis of the hybrid system is the intelligent building management system (smart home) developed by the applicant, identified by the INSYTE trademark registered in the applicant's name (Certificate No. 395219). The system consists of a SPIDER-Z controller and a number of executive (remote, managed) modules connected to the controller by radio and by wire. The main feature of the system is the simultaneous transmission of data over the wired RS-485 bus and over the air, GSM networks, Ethernet networks (LAN, Wi-Fi), 1-Wire, RS-232. The Modbus RTU and Modbus TCP / IP protocols are used over the wires, and the ZigBee wireless protocol over the radio. The system was developed by deeply modernizing the LanDrive2 wired bus distributed building automation system, which has been produced by the applicant since 2007. LanDrive2 is the second improved version of the wired system.

LanDrive2 wired system is a highly integrated universal modular software and hardware complex designed to control all subsystems in the building, such as: power supply; lighting; climate control (control of air conditioners, heating, ventilation, humidity); saving of thermal energy, electricity, gas, water; fire alarm; protection against water leaks; gas leakage protection; collecting data from gas, water, electricity meters; access control to the premises; CCTV; sun protection (control of roller shutters, curtains, blinds); management of audio and video equipment; notification of events on GSM channels; local and remote control of all subsystems (locally and via the Internet). The LanDrive2 system allows full control over the building from one operator’s location, and in case of use in apartments and private houses - from one control panel, wall, tablet or smartphone. The LanDrive2 system is scalable, which allows you to install it not only in small apartments, high-rise administrative and residential buildings, but also in groups of buildings and entire areas. Structurally, the system consists of a controller and executive modules, interconnected by a twisted pair RS-485 network. Managed equipment is connected to the executive modules. For communication, the well-known Modbus / RTU protocol is used. Thus, the LanDrive2 system is open, and control commands are applied to each product in the series. The equipment supports Modbus standard communication rates of 2400, 4800, 9600, 19200, 38400, 57600, 76800, 115200 kbit / s, which is sufficient for instant command execution and does not impair communication quality over sufficiently large distances up to 1.5 km. The maximum number of devices controlled by one controller is 247. It is possible to combine several SPIDER controllers in one network. Power is supplied from a stabilized industrial power supply. For absolute reliability, it is recommended to install uninterruptible power supplies on batteries. Due to the widespread Modbus / RTU protocol, third-party equipment can be included in the system, for example, the connection of graphic control panels, room thermostats, sensors, etc. It is also possible to use the LanDrive2 series devices in other systems. Using any Modbus OPC server, it is possible to control the system without a controller as such, from a computer acting as a controller. Integration into any SCADA system is also possible.

Based on the LanDrive2 system, the applicant has developed a wireless intelligent building management system (smart home) by adding a wireless cluster integrated into the LanDrive2 system, which resulted in a qualitatively different, hybrid building management system that has no analogues. On the basis of such a hybrid system will be built: intelligent systems "Smart Home" for private customers; building management systems for organizations and enterprises; systems for collecting data from electricity, gas, hot and cold water meters, collective security management systems for microdistricts and districts, cities, such as urban lighting control without wires, urban security systems.

The hybrid system controller is a programmable logical GSM-controller (model SPIDER-Z), developed by the applicant specifically for solving automation problems in residential, office and industrial premises. The controller is designed to operate on an RS-485 network using the Modbus / RTU protocol and the LanDrive2 distributed bus system, as well as on a wireless network using the ZigBee protocol. It can be used in other systems using the Modbus protocol. The controller has the following built-in nodes: a powerful ARM processor; real time clock; non-volatile real-time calendar with automatic functions for the translation of winter and summer periods; a battery that protects the watch and calendar from resetting when external power is turned off; RS-485 port for controlling LanDrive2 system; RS-232 port for controlling Multiroom receivers and other equipment; GSM-modem for system management and user alerts; USB port for programming the controller and real-time control via PC; Ehernet-port for remote control of the controller and system; 0-10V analog inputs (current loop) for connecting sensors, security and fire alarm loops, 2 pcs; discrete inputs with counting mode for connecting sensors or counters of electric energy, water, gas, 4 pcs .; 1 Wire port for connecting I-Button keys, LD2-TS temperature sensor; relay outputs, changeover contact, 4 pcs .; ZigBee-modem for managing ZigDrive wireless networks; battery built into the controller housing.

All controller ports are optically and galvanically isolated. The controller is equipped with a GSM antenna; USB cable for programming. Using it, you can create:

• wired networks of the "smart" home INSYTE LanDrive2;

• wireless networks "smart home" INSYTE ZigDrive;

• integrated systems for collecting and accounting data on resource consumption, AS-KUE via Ethernet, Internet;

• fire alarm systems, including GSM networks;

• warning systems and remote control via GSM, Ethernet, Internet;

• access systems;

• water leakage and gas leakage systems;

• climate control systems;

• multi-room equipment control systems;

• dispatching systems, distributed control and monitoring over the Internet and local networks, including groups of buildings in cottage villages, mobile stations, treatment facilities, server-based networks over GSM, Ethernet, Internet;

• automatic reserve input systems (ABP),

• boiler room control systems via GSM, Ethernet, Internet.

Peripheral equipment is connected to the controller through executive modules (wired and wireless).

 These include: 1) managed relay modules in two versions - a miniature version for installation, for example, in cups of sockets for switches and sockets, as well as in a version for mounting on a DIN rail, which have a large switched power; 2) controlled dimming modules of two modifications - in the modification of modules requiring a zero and phase input, and in the "discontinuous" modification, which are more convenient for installation in switch glasses where zero is not drawn; 3) infrared communication modules, namely transceivers (transceivers) of infrared signals, which are built-in, are equipped with a brushed metal panel coated with varnish of various colors, are universal, allow you to recognize, remember and play IR commands of any manufacturer; 4) modules with digital inputs, which are made in miniature enclosures, which allows them to be embedded in standard switch glasses, while sensors having dry contact outputs are connected to the module terminals; 5) expansion modules for connecting sensors with a universal number of control inputs and outputs (located in DIN enclosures); 6) motion sensors, lighting, etc. various manufacturers; 7) stabilized industrial power supplies of appropriate power.

The operation of the system is that the controller, having the building management scripts in it, collects information and sends commands to the executive (distributed over the building) modules. In this case, programming of the controller and executive modules is necessary. For this, the LanDrive ConfiguratorPro program is used, which can be downloaded from the DOWNLOAD section of the INSYTE company website (www.insyte.ru). The program has a simple and intuitive interface, as well as a detailed help section. Programming is carried out from a personal computer via a USB port or an Ethernet connection. After programming, the computer is not used to operate the system.

Thus, according to the programmed scenarios, the controller controls the network of wired and wireless executive modules, which in turn control various peripheral devices connected to them.
