Description

Intelligent infrared dimming control system

Technical Field

The utility model relates to a dimming control technical field specifically is an infrared dimming control system of intelligence.

Background

At present, the application technology of the LED lamp is mature, the number of the LED lamps required in different application scenes is increased day by day, and the driving management of various LED lamps is also improved. The existing lighting control products used in a matched manner in a building cannot completely cover all application scenes, the dimming device of the existing lighting control products sets parameters of a lighting controller through a serial communication interface so as to achieve the purpose of dimming, and the mainstream dimming mode is 0-10v, PWM and silicon controlled rectifier dimming mode. The LED drive is divided into a drive power supply with an LED and a linear constant current power supply. The LED driving power supply is usually driven in a 0-10V mode and in other dimming modes with weak current control signals; the linear constant current adopts a silicon controlled rectifier dimming mode, and most of people perception adopts a microwave radar or a pyroelectric infrared sensor.

The microwave radar or the pyroelectric infrared sensor is additionally arranged on the independent illuminating lamp, and the illuminating lamp capable of sensing the human body can be assembled. The microwave radar can sense moving objects, such as: people walking, animals, vehicles traveling, etc. The pyroelectric infrared sensor is used for sensing the existence of a human body, namely, people who move or are still can be sensed by the pyroelectric infrared sensor. The human body perception type lighting lamp is usually opened or closed, namely the lamp is on when a person is in the lighting lamp, and the lamp is off when no person is in the lighting lamp. Or a preset illumination mode is adopted, namely the lamp is full-power when people exist, the lamp is full-power when no people exist, and the preset power is generally in a 20% -50% full-power illumination interval.

In the aspect of indoor building illumination control, the adopted dimming scheme is that the illumination adjustment is carried out by using an integrated dimming module, the integrated dimming module is generally compatible with a 0-10V PWM form, meanwhile, the illumination lamp is required to support a corresponding dimming mode, and particularly when the PWM dimming is used, the compatibility matching of the lamp and the integrated dimming module is required to be consistent, and the lamp and the integrated dimming module can be normally used under the same frequency. For the 0-10V dimming mode, the lamp and the dimming module are required to be tested in advance, and the dimming effect can be achieved only by determining whether the dimming voltage output by the integrated dimming module is consistent with the dimming voltage output by the lamp. On-load capability of the integrated dimming module, the one-way dimming load does not usually exceed 6A. The integrated dimming module is linked with an access control system and is in butt joint with a central control platform for identifying the entering and exiting of personnel, or the integrated dimming module is used for setting strategies at different time intervals to meet the application scene requirements of adjusting the personnel to different illumination intensities at different time intervals. When the whole large-area illumination area needs to be dimmed, microwave radars or pyroelectric infrared sensors are arranged in all coverage areas at certain intervals, so that the detection range of the sensors is enough to cover all indoor spaces. The ideal effect can be achieved.

At present, a few large-scale integral dimming devices for LED lamps adopting a linear constant-current scheme are available in the market, a knob type 86-box dimmer is often used for adjustment, the adjustment belongs to physical adjustment of potentiometers, and the adjustment cannot be applied to lamps adopting all linear constant-current schemes, cannot be digitally controlled and cannot be connected to an intelligent control system.

Because the load capacity of a single integrated dimming module is limited, the quantity of control lamps of the integrated dimming module is limited, when large-area unified dimming is performed, a plurality of groups of integrated dimming modules are required to be used simultaneously, the whole dimming effect of a large-area lighting area can be achieved, the cost of a dimming control unit is increased, the complexity and the volume of a lighting control box are increased, and due to the fact that the installation space of a plurality of application scenes is limited, the large-area unified dimming cannot be performed by using the integrated dimming module.

The dimming mode of the existing integrated dimming module is 0-10V or PWM, and the lamp is required to have corresponding dimming function, if the frequency of the lamp is different from that of the PWM mode of the integrated dimming module, dimming cannot be performed, and when the compatibility of the 0-10V mode is not good, the phenomenon that the lamp cannot be turned off or only a half-range dimming range is available can also occur.

In installation, the lamps need not only provide AC 220's power supply, still need arrange the signal line of adjusting luminance between integrated module and every lamps and lanterns or every group lamps and lanterns of adjusting luminance, and this has not only increased the construction degree of difficulty, the later maintenance of also being convenient for, and the module of adjusting luminance of lamps and lanterns side still can shorten the life of lamps and lanterns.

The system is in butt joint with the entrance guard and the central control platform on the recognition of the entrance and exit of people, the workload of butt joint with an entrance guard system is increased, the cost of butt joint of materials, wiring and software for project implementation is increased, the time period of project implementation is prolonged, and butt joint adaptation of all systems cannot be achieved on application.
