Control plan for public walkways
Method 1: Directly control the lighting fixtures with strong current detectors
Corridors generally use energy-saving down lights, LED and other light sources. It is recommended to use a 1-10Vdc dimming signal on walkways with lighting conditions near external windows
The independent light sensing probe with output can automatically adjust the brightness of LED or energy-saving lamp based on the intensity of sunlight (or directly switch the lamp), without the need for a system< br />
The dimming signal 1-10VDC output of the probe can directly control the dimming ballast on the lamp (with 1-10V interface), such as the Shanghai Coca Cola project
It is recommended to use dynamic and static detectors with ultra long distance detection function in long corridors (detection distance can generally reach 15-25 meters), and install them on the ceiling
Infrared dynamic and static sensors with an ultra long detection range
These probes can be used independently without entering the system and powered by 220VAC. Directly control the lighting fixtures< br /> Design method:
1. Determine the number of dynamic and static probes based on the length of the corridor and the detection range of the dynamic and static probes< br /> 2. Determine the window corridors that require light sensing, with one light sensing probe per corridor< br /> 3. The 220VAC power supply for the strong current independent dynamic and static probes and light sensing probes is directly provided by the MCB air switch in the lighting box< br /> 4. The power supply of the lamp is provided by the relay output of the dynamic and static probes; But it is necessary to consider the maximum load value that the relay of the dynamic and static probes can carry; If the load exceeds the maximum load value, the probe output should be used to control the wire package of the contactor, and the contactor should be used to load the lamp, as shown in the following figure:
Method 2: Network type detectors and switch (or dimming) control modules form a control system
Using network-based dynamic and static probes or light sensing probes, these intelligent probes continuously detect whether there are people or light intensity values in their area.
After judging the data of the probe itself, a digital control signal is output to the network bus of the MP intelligent system, which can control the MP intelligence
Various control modules on the system. Specific application cases include: Building 1, Administrative Service Center, Xuhui District, Shanghai; Building 2
Design method:
1. Divide the lighting fixtures to be controlled into circuits< br /> 2. Configure corresponding dimming or switch control modules according to circuit division< br /> 3. Determine the number of dynamic and static probes based on the detection range of the detectors and the length of the corridor< br /> 4. Determine the corridor by the window, and use one light sensing probe for each daylight corridor by the window< br /> 5. The power supply for network type dynamic and static probes and network type light sensing probes is supplied by the MP control box through network cables< br /> 6. The power supply of lamps is provided by the switch or optical module in the MP control box, which is connected with the control panel; There is no wiring between probes, etc< br />
