Description

The utility model relates to energy-saving lighting systems and can be used for automated control of outdoor and workshop lighting networks.

Currently, there is a problem of developing a device for intelligent lighting for various purposes based on a modular software and hardware platform, including subsystems, components and software that ensures the smooth and efficient operation of the software and hardware platform. Using a platform consisting of a large number of heterogeneous devices that require constant management and control and the use of an appropriate architectural solution. The device must provide the functions of control, monitoring and diagnostics of the operation of luminaires, connection of electrical equipment (protective devices, contactors, etc.).

From the prior art, an energy-saving wireless street lighting control controller is known, installed on a lighting line pole, connected to two lamps or to two sections of one lamp, containing a GSM / GPRS module with an antenna, a control unit for two segments of the lamp, two channels for controlling external objects connected with a control unit for two lamp segments, a microprocessor that provides processing of information received from external objects and control of a GSM / GPRS module, connected to a GSM / GPRS module with an antenna for continuous two-way communication with a control and data processing center via the Internet, a control node for two segments lamp on a pole. A controller of this type provides energy savings in street lighting networks and automatic control of switching on and off lamps on lighting poles (RU 128813 U1, H05B 37/02, publ. 05/27/2013).

The disadvantage of this utility model is that the presented unit controls only two outgoing lines, which can create current asymmetry in three-phase power networks due to phase load inequality (phase imbalance) and adversely affect the power quality in lighting lines.

Known block of automated lighting control with the possibility of address control of each lamp, containing a programmable GSM-module using it as the main communication channel and the main logic module, having channels for monitoring the status of power equipment, characterized by the presence of a moisture and dustproof housing with two built-in RS485 interfaces, main and backup SIM-cards and separate logic and I/O boards (RU 175522 U1, published 12/07/2017, G05B 11/32).

The closest technical solution is known from patent document CN 102316639 A (IPC G08C 17/02; H05B 37/02, publ. , street light control switch or street lights, while the GPRS controller, control switch and street lights are connected in series, the street light control switch is also connected to the power supply, in addition, the street light is connected to the ground wire. The remote switching loop has the advantage that with the built-in monitoring of the GPRS controller, the requirements of urban landscape lighting or street lights are met at the same time, and the lamp lighting time is effectively shortened, so a large amount of electricity is saved.

The disadvantage of these technical solutions is the impossibility of connecting Russian electricity meters, which is unacceptable for use on the territory of the Russian Federation, as well as the lack of backup communication channels, which is poorly applicable in territorially remote areas or in the event of problems with one of the mobile operators, which can lead to lack of control and management of such a block.

The objective of the claimed utility model is to develop a control controller with a system of actuators that provides the functions of control, monitoring and diagnostics of the operation of lamps and electrical equipment.

The technical result of the claimed utility model is to ensure energy savings and lamp life, continuous remote and automatic control of various modes and various equipment, such as air conditioning, heating, control of blinds or curtains servo drives, integration of the throughput system of an object, obtaining a streaming video channel from surveillance cameras, control lighting and architectural lighting.

The technical result is achieved by the fact that the universal control controller contains a housing in which a functionally interconnected multi-contact bus with the CAN protocol, a control module, a DALI expansion module, including a control unit using the DALI/DALI 2.0 protocols, a communication module with an Ethernet 100 channel, are installed /1000, power converters, built-in storage and PLC expansion module, including a computing unit, a communication unit with a universal control controller, a functioning control unit and an indication unit.

In a particular implementation case, the universal controller may comprise an NB-IoT extension module.

The device is explained by the graphic part:

Fig. 1 - block diagram of the claimed device, isometry;

Fig. 2 is a general view of the claimed device.

The universal control controller is designed as follows. In case 3, functionally interconnected multi-contact bus 4 with CAN protocol, control module 2, DALI expansion module 1, including control unit 11 using DALI/DALI 2.0 protocols, communication module 5 with Ethernet 100/1000 channel, power converters 6 , a built-in drive 8 and a PLC expansion module 9, including a computing unit, a communication unit 10 with a universal control controller, a functioning control unit 7 and an indication unit 12.

In a particular implementation case, the universal controller may comprise an NB-IoT extension module.

The claimed universal control controller can be made in a plastic case with DIN rail mounting. For connecting wires and organizing a detachable electrical connection, detachable terminal blocks are used, which ensures convenient installation, simple dismantling and replacement of the unit. The lighting control controller is powered by a DC supply voltage of 24 V ± 10% through a power converter. The lighting automation controller has a number of universal isolated inputs/outputs that have surge protection, some of which can be configured as outputs. The inputs can be used to connect sensors of the "dry contact" type or serve as discrete mains voltage inputs. The choice of one of the three functions of the universal inputs/outputs is carried out at the stage of assembling the printed circuit board by installing the appropriate electronic components. This achieves satisfactory flexibility that eliminates the need to develop and upgrade hardware.

The control controller combines a number of solutions that make it possible to significantly increase the performance of the system due to the execution of the unit based on a modular platform with a connection between components via a multi-contact CAN bus. The control controller allows you to connect up to 10 expansion modules for various purposes to combine all the engineering systems of the control object in the control system. The controller is powered by an external power supply at 24V ± 10%, which means protection against power surges.

The division into various expansion modules allows the device to remain operational when the rated voltage is exceeded by several tens of times. Even in the event of a physical failure of the input-output board (including fire), a separate logic board remains operational and allows the dispatcher to transmit information about the critical state of the object.

High-quality communication of the control controller is provided by connecting via a cable channel Ethernet 100/1000. This allows you to stay in touch with the server and the control center in case of a complete failure of one of the cellular operators. Also, if the connection is interrupted or lost via the Ethernet 100/1000 cable channel, the system remains operational and continues to work offline according to preset algorithms.

The controller is connected to single-phase and three-phase power meters (electricity meters) via RS-485 interface with support for standard protocols of electricity meter manufacturers. Also, with the help of expansion modules, it is possible to connect various metering devices for housing and communal services (water supply, gas) for data collection and technical accounting.

Remote control of lighting modules is carried out by connecting via a wire line with simultaneous transmission of supply voltage and control signals via power wires (PLC), provides high noise immunity without using the radio frequency range. The small amount of transmitted data allows the use of a large number of modules on one line. The PLC also allows you to transfer diagnostic information from the lighting modules to the controller in the reverse communication channel.

PLC lighting modules are controlled by the software platform of the complex (PP PAK) with support for the MQTT-Sparkplug protocol, which provides the necessary level of reliability and information security.

The pre-installation of the DALI expansion module allows you to control lighting and various devices based on the DALI 2.0 control protocol, building various operation algorithms using combined motion and light sensors, setting up manual control in place using wall control panels, implementing individual or group dimming of lighting devices.

Additionally, the controller may contain an NB-IoT expansion module that performs wireless data transmission according to the cellular standard for devices with low data exchange volumes LTE Cat NB1. In this way, it is possible to build a large amount of star control groups without the use of control cables and a 100/1000 Ethernet channel cable.

The LoRa station is an expansion module for providing lighting control and data collection from LoRa devices over a radio channel in the license-free radio frequency range of 863-870/873 MHz. LoRa provides long distance transmission with low power consumption. The data rate can reach from 0.3 kbps to 27 kbps depending on the spreading factor.

The analog expansion module and the digital expansion module have several input signals and allow monitoring the state of the power section and control cabinet elements, such as line voltage, status contacts. And also to control the power devices of the power supply panels of the equipment.

The PLC expansion module includes a computing unit, a communication unit with a universal control controller.

The control controller is divided into a logical part and an input-output part, which provides galvanic isolation from the mains, increased protection against overvoltage and interference from lightning discharges, as well as improved maintainability and simplified device upgrades in the future.

To connect meters and various expansion units, the automated lighting control unit uses 2 RS-485 interfaces with isolation and protection against electrostatic discharge and overvoltage.

The control module for the operation of the automated control unit is programmed using the computing module of the system based on the Elbrus architecture.

In the claimed control controller, diagnostic and other information about the state of the subsystem and connected equipment is transmitted. The transmitted information from the universal control controller to the upper-level software is protected from unauthorized access. Provides the inability to read the contents of the firmware, the ability to use authorization of users and devices (login/password, the use of SSLv3/TLS1.1 crypto protocols, the use of algorithms for generating and verifying digital signatures, the use of AES-128/192/256 encryption algorithms, support for crypto protocols, digital signature and encryption algorithms due to software implementation and/or use of the MIK51SC72D microcontroller for CIPF.

The control controller provides for the use of a wired connection, which increases the reliability of performance. The lighting control controller provides the following types of indication: exchange via RS-485 interface, presence of external power supply. The power wires are connected to the connectors on the I/O Board. This allows you to isolate the Logic Board from the high voltage coming through the connected wires, both galvanically and physically, which reduces the likelihood of failure of the Logic Board in an abnormal situation. The device is turned on by applying voltage to the power terminals. Built-in power supply ensures the operation of electronic circuits.

The microcontroller turns on the system and controls the outputs and controls the inputs on the I/O board. To operate the management controller on a 100/1000 Ethernet network, the cable is connected to the network. When the supply voltage appears or when the power fails, as well as when any of the signals changes, the control controller registers the change, generates an event and, if there is a connection, sends it to the built-in storage device (8). Sending system events and data events can be done to a remote server with delivery control, which ensures the integrity of the information. Thus, the loss of events during regular operation in the event of a power failure is excluded.

When operating autonomously, the control controller executes all commands according to a predetermined schedule with the help of a functioning unit. For remote control, there is a mechanism for performing tasks that are set in the software of the collection server. So, engineering or operational personnel can set tasks for the automated lighting control unit on the collection server and monitor the result of their implementation.

The universal controller provides control of various types of devices with various data exchange protocols by connecting expansion modules for various purposes via the CAN bus. It transfers data to external software with extended functionality for monitoring and controlling equipment. The use of a housing with a multi-pin CAN bus provides easy installation and wireless connection of additional expansion modules. The universal control controller allows you to control such systems as air conditioning, heating, control of blinds or curtains servo drives, integration of the object's access system, receiving a streaming video channel from surveillance cameras, lighting and architectural lighting control.
