Design and Application of Acrel Smart Lighting Control System in Schools

摘要：照明用電是學(xué)校一項基本的電力需求，學(xué)校具有區域大、房間多、燈具數量多、休息時(shí)間基本固定等諸多特點(diǎn)，若采用傳統的照明控制，往往布線(xiàn)繁多、不能充分利用自然光照而造成電力浪費，且控制麻煩，即使嚴格管理，仍不可避免地由于忘記關(guān)燈而造成巨大的能源浪費。為了達到節能優(yōu)化的控制效果，學(xué)?？刹捎弥悄苷彰骺刂葡到y來(lái)管理學(xué)校照明。智能照明控制系統與傳統的照明控制方式相比較，布線(xiàn)簡(jiǎn)潔，控制靈活方便，可以節約電能。

Abstract: lighting electricity is a basic power demand of the school. The school has many characteristics, such as large area, large number of rooms, large number of lamps and basic fixed rest time. If the traditional lighting control is adopted, the power waste is often caused by many wiring, unable to make full use of natural light, and the control trouble is inevitable because of forgetting to turn off the lights. In order to achieve the control effect of energy saving optimization, schools can use Smart lighting control system to manage school lighting. Compared with the traditional lighting control mode, the Smart lighting control system has simple wiring, flexible and convenient control, and can save electric energy.

0.前言 Background

安科瑞智能照明控制系統（以下簡(jiǎn)稱(chēng)：系統）基于KNX總線(xiàn)技術(shù)，采用四芯屏蔽雙絞線(xiàn)將面板、傳感器、驅動(dòng)器和總線(xiàn)電源等所有的控制模塊手拉手連接起來(lái)，將各種獨立的控制功能集成到一個(gè)系統中，集舒服、靈活、安全、節能經(jīng)濟、維護方便等諸多優(yōu)勢于一體。

智能便捷的控制方式還可以滿(mǎn)足學(xué)校照明的各種控制需求。下面介紹安科瑞智能照明控制系統在某中學(xué)的設計與應用，簡(jiǎn)析KNX技術(shù)的設計規范，概述安科瑞智能照明控制系統的具體架構、控制方式等.

Acrel Smart Lighting Control system (hereinafter referred to as the system) is based on KNX bus technology, using four-core shielded twisted-pair wire to connect all control modules, such as panel, sensor, driver and bus power supply hand in hand, and integrates various independent control functions into a system, which integrates many advantages, such as comfort, flexibility, safety, energy saving and economy, and convenient maintenance.

Smart and convenient control mode can also meet the various control needs of school lighting. Here is the design and application of Acrel Smart lighting control system in a middle school, a brief analysis of the design specifications of KNX technology, and an overview of the specific structure and control mode of Acrel Smart lighting control system.

1.系統組成system composition

系統組成結構圖如圖1所示，總線(xiàn)電源、驅動(dòng)器、網(wǎng)關(guān)、耦合器、輸入模塊等需安裝在配電箱內，傳感器一般安裝在公共區，面板和觸摸屏一般安裝在房間值班室內。注意各模塊接線(xiàn)不能組成環(huán)形。相對小型的項目，系統可選用10寸中控屏，它無(wú)需IP網(wǎng)關(guān)轉換協(xié)議，設置簡(jiǎn)單且成本低。對于相對大型的項目，可通過(guò)IP網(wǎng)關(guān)連接到電腦，實(shí)現終端遠程控制。

The structure diagram of the system composition is shown in figure 1. The bus power supply, driver, gateway, coupler, input module and so on need to be installed in the distribution box, the sensor is generally installed in the common area, and the panel and touch screen are generally installed in the room duty room. Note that each module wiring can not form a ring. A relatively small project, the system can choose 10 inch central control screen, it does not need to IP the gateway conversion protocol, simple setting and low cost. For relatively large projects, the terminal remote control can be realized by connecting to the computer through the IP gateway.

1) Automatic control:

In common areas such as walkways and elevators, two-in-one sensors can be installed to monitor the illumination of the current environment and whether there is any activity, and to realize automatic control. In the case of sufficient illumination (such as sunny days, noon), someone or no one, the lamp will not light; in the case of insufficient illumination (such as rainy days, nights), someone lights on, people go, the delay lights out.

The illuminance sensor is installed in the window position of the classroom, the teacher's office and other functional areas, and the current illumination situation is monitored in real time. When the illumination is sufficient, the lamp in the window position is automatically closed, and the natural illumination is fully utilized.

2) manual control:

Each classroom, office door is equipped with Smart panel, which can realize manual control of room lighting. Panel can achieve one-to-one, one-to-many control.

3) scene control:

For the school landscape lighting, teaching building hall lighting, important conference room lighting can be based on the control needs of different scenes, set up a variety of scene modes in advance, and by the staff on duty one-click switch.

4) timing control:

According to the time of school early reading and next evening self-study, the system sets the timing switch to complete the automatic control of lighting and ensure the reduction of energy consumption during non-working hours.

5) computer centralized monitoring:

The computer end control page mainly has the home page, the floor control page composition. It can realize remote centralized control, feedback the switch state of field loop in real time, and facilitate remote monitoring of duty personnel.

Monitoring software consists of title bar, task bar and working interface. Title bar: mainly reflects the project name and time. Navigation bar (task bar): you can switch between any page, select. Work interface: according to the floor and room layout, the control is simply divided, can achieve single lamp control, multi-loop control and other control functions.

The home page is used as the starting page of the system. The setting content can generally present the project introduction, project effect diagram, project plan, or project structure diagram according to the customer's request. The concrete setting is based on the actual requirements, as shown in figure 2.

The project has a number of floor control pages, with the classroom as the control unit, each classroom has a lighting circuit single switch and main switch, fan air conditioning single switch and main switch, socket power single switch and main switch, floor main switch and field state feedback two state quantities, In addition, there is a timing switch to facilitate users to set their own timing control time.

The wiring is simple and flexible, each module can work independently without influence, and the system reliability is higher. Module working in DC 30V safe voltage, user operation is more secure. When upgrading or changing system functions, you do not need to turn off the whole system, just change the device parameters. System alarm positioning function, real-time monitoring and upload centralized control end, convenient equipment personnel accurate positioning and timely repair. The following is a detailed introduction to the design process of the system through some project drawings.

1）結構拓撲圖

系統結構拓撲圖（見(jiàn)圖3）是對項目實(shí)施整體結構布局的一個(gè)規劃，如圖可知，該學(xué)校共有A、B、C三棟樓設計了智能照明控制。由于每一層箱子比較多，所以布線(xiàn)的時(shí)候按樓層進(jìn)行支線(xiàn)劃分。同一支線(xiàn)內所有的控制模塊都通過(guò)總線(xiàn)線(xiàn)纜連接到一起，每條支線(xiàn)的所有數據量匯總到耦合器、網(wǎng)關(guān)，再經(jīng)由交換機到達監控室，實(shí)現遠程集中控制。

2）配電系統圖Distribution System Diagram

配電系統圖主要明確了控制回路，所需的控制模塊及其數量，方便后期ETS配置系統功能。以某教室智能照明配電系統圖（見(jiàn)圖4）為例，可以看到該配電箱共分配了一個(gè)12路開(kāi)關(guān)驅動(dòng)器，箱內模塊可通過(guò)總線(xiàn)線(xiàn)纜連接到現場(chǎng)控制面板、傳感器等設備。

Distribution system diagram mainly defines the control circuit, the required control module and its number, convenient for the later ETS configuration system function. Taking the diagram of Smart lighting and distribution system in a classroom (see figure 4) as an example, it can be seen that the distribution box is allocated a 12-way switch driver, and the module in the box can be connected to the field control panel, sensor and other equipment through the bus cable.
