The application of intelligent control system in subway lighting analysis

Subway lighting as an important transport hub lighting, is almost entirely dependent on artificial lighting, to fulfill the requirements of environment illumination uniformity, no dark side of the station, but due to the daily operation of also should consider to minimize unnecessary lighting. Therefore, the intelligent control system is also in the subway is applied more and more common in lighting. Shenzhen metro line 9 ( Merlin line) Is one of the subway lines in shenzhen at present, the lighting design in the shenzhen metro consistent style, for the LED tube light, etc. The application of lamps and lanterns is also quite common. And intelligent control system for the LED tube light, represented by the scientific regulation of lamps and lanterns, more prominent feature of shenzhen metro. Subway illumination need intelligent controller, is due to the following characteristics: ( 1) Because of the station operation for a long time, lighting lamps and lanterns should be open for a long time. ( 2) The station space area is larger, the number of lamps and lanterns is more, the demand for building energy saving is higher. ( 3) Stand my wife traffic dense, passengers to intensity of illumination requirement is higher, the traffic, the greater the need to open the more the number of lamps and lanterns is relatively. ( 4) Uneven distribution of passenger flow, different operation time, the different intensity of illumination requirements in different areas. ( 5) Need to electrical control device management area and type is more, such as the station concourse platform, change to the channel, advertising lighting, etc. The subway project requirements for LED tube light, LED lighting lamps and lanterns to realize two-way communication, in order to meet the requirements of wisdom for city lighting intelligent, can both meet the LED tube light, etc. The lamps and lanterns that move light control, and can monitor these at the same time the real-time status of lamps and lanterns, accumulation of energy and life, and required to achieve single lamp single control 100%, it involves the application of intelligent control system. As is known to all, intelligent lighting control system with remote control, single lamp single control and other unique advantages, to meet the strict requirements in the field of complex control light. The intelligent control system is the main function is as follows: 1, the switch module can be realized by connection circuit of lamps and lanterns of the intelligent function of open and close. According to the preset scene mode or clock automatically to any control circuits of lamps and lanterns, achieve the expected illuminance value, to achieve different scenarios. 2, switch of the module circuit open function can avoid the surge current on the impact of the lamps and lanterns, extend the life of the lamps and lanterns. 3, since the feedback type switch module, which can realize the running time of lamps and lanterns, lights, real-time detection, and the record store. Lamps and lanterns for the analysis of energy saving and the whole life cycle maintenance to provide data support. Also can judge the fault circuit quickly, save operating personnel maintenance inspection time. 4, touch screen control panel and scene, all can be the scene of lamps and lanterns for the area control mode. Control panel can be done to a key to default mode of operation; Touch screen control mode can realize more scene definition and the intensity of illumination adjustment function, meet the needs of different levels. 5, station operation personnel can through the clock control module, according to the preset scenes in the different periods, timing to open the corresponding mode, can realize the lamps and lanterns, single loop, group control, and more flexible functions. Subway station intelligent lighting system automatic operation mode in operating time ( At 7:00 - 24:00) Typical preset scenario, infrared sensing monitoring function open mode, platform for the station hall opened a third 1/2 lighting lighting lighting or lighting or open mode. Analysis of energy saving effect, every car station hall of shenzhen metro station public areas according to the 2000 sets of 80 18 h calculated wled canister light, daily operation, traditional lighting power consumption is about 2880 KWH 1 d; Public area lamps and lanterns is full of electricity open time is approximately 13 h, intelligent lighting 1 d power consumption of about 2080 KWH. Intelligent lighting system energy saving 20%, 30%, energy-saving effect is very obvious. Compared with the traditional subway lighting, lighting scheme of shenzhen metro shows its remarkable energy saving, intelligent control, high reliability and system compatible ability: metro monitoring center real-time control lighting lamps and lanterns, and access to state and life of lamps and lanterns, comprehensive implementation of the subway system into wisdom urban system; Intelligent controller reliability and systematical compatible ability, let the subway central control system error-free to monitor each of the lamps and lanterns. In general, represented by the shenzhen metro line 9 of lighting design, will ably LED downlight lamps and lanterns is combined with intelligent control system, such as more efficient and effectively fulfill the functional lighting of the subway.
