As an alternative embodiment, the first lighting module 4 is a high-pressure sodium lamp or a light emitting diode; the second lighting module 6 is a high-pressure sodium lamp or a light-emitting diode.
The operation of the lighting control system of the above embodiment is described below.
After a system main switch is turned on, the lighting control system can provide two working modes for a user to select, namely a full-automatic control mode and a manual control mode. First, the fully automatic operation mode of the system is explained. When the system mode switch is selected to be the automatic mode, the time control module and the ambient light detection module in the lighting control system of the embodiment are simultaneously activated, and the illuminance adjusting switch is disabled. Specifically, firstly, the time module detects the time of the city where the system is located, and transmits the time data to the master control module; and meanwhile, the ambient light detection module collects ambient light data of the city where the system is located, calculates a reasonable threshold value of the switch of the lighting module, and transmits the data to the master control module. The overall control module will aggregate the data from the time module and the ambient light detection module and then determine whether the base lighting module (the first lighting module) needs to be turned on. The main control module is used for judging that the priority is that light data is prior and time data is auxiliary.
For example, if the weather is good, then the time is close to the evening, the monitoring frequency of the ambient light monitoring module accelerates and collects current light data, and transmits the data to the master control module, the master control module performs averaging or majority counting operation on the collected light data, and compares the data with a switch threshold, after the data reaches a set threshold, the master control module transmits an illumination turn-on signal to the basic illumination module, and meanwhile, the light monitoring frequency of the ambient light monitoring module is greatly reduced, after the basic illumination module receives the turn-on signal, the basic illumination lamp set is turned on, and the minimum illumination meeting the illumination specification is continuously provided for the city until the next morning, and under the condition, the system is in a state of saving energy to the maximum extent. When the basic lighting module (the first lighting module) is turned on, the obstacle sensing module is operated, and the auxiliary lighting module (the second lighting module) is in a standby state. When barrier response module passes through the sensor and detects the regional interior barrier that has, when having pedestrian or vehicle promptly, barrier response module can be with sensing signal transmission to total control module, can open auxiliary lighting's signal transmission to auxiliary lighting system after total control module has handled this signal, auxiliary lighting banks will open when then, provides better visual environment for pedestrian and vehicle, guarantee traffic safety, improvement transportation efficiency. When the vehicle or the pedestrian passes through the lighting area, the second lighting module can not be immediately turned off, and the turning off of the second lighting module is set for a delay time to reduce visual discomfort caused by sudden change of illumination on the pedestrian and the vehicle, so that danger is generated.
In early morning and dawn, the monitoring frequency of the ambient light monitoring module is accelerated again, the current light data are collected and transmitted to the master control module, the master control module performs averaging or majority counting operation on the collected light data again, the data are compared with a switch threshold value, after the data reach a set threshold value, the master control module transmits an illumination closing signal to the basic and auxiliary illumination modules, meanwhile, the light monitoring frequency of the ambient light monitoring module is greatly reduced, and after the basic and auxiliary illumination modules receive the closing signal, all the lamp groups are closed.
After all lamp sets are turned off, the ambient light monitoring module carries out periodic monitoring and transmits monitoring data back to the master control module. This is done to cope with sudden dark conditions of the sky, such as solar eclipse, rainy weather, etc.
In bad weather conditions, such as daytime in cloudy or rainy weather, the system will weaken the function of the time module, i.e. only for time reading, but the time data does not play a decisive role in the switching of the lighting system. The judgment mode of the lamp group opening is changed into a unilateral decision by the data of the ambient light monitoring module. The specific process is to accelerate the monitoring frequency of the ambient light monitoring module and increase the delay of the starting of the lighting module. This is done to reduce the chance of the lighting system being subjected to frequent switching of the system due to intermittent brief dimming of the ambient light in cloudy, rainy weather. When the weather is continuously dark and causes the urban visual environment to be poor, namely, the main control module performs a majority or average operation on the ambient light data returned by the ambient light monitoring module within the duration time, when the processed data value is close to a threshold value of the fine weather at evening time, the main control module sends a lamp group starting signal to the basic lighting module, and after the basic lighting module receives the signal, the basic lighting module is started and continuously provides the lowest illumination meeting the lighting specification for the city. And the time module judges the time in the evening in advance, and after the time module transmits the signal entering the evening to the master control module, the master control module sends a starting signal to the obstacle sensing module, the obstacle sensing module starts to operate, and the copied lighting system enters a standby state. The subsequent lamp group control flow is similar to the light control flow at night in fine weather.
The lighting system start-up conditions in the automatic case are shown in table 1:
TABLE 1
| Time module data | Ambient light detection module data | Starting state |
| Night | Less than set data | Basic lighting module turning on immediately |
| Daytime | Greater than the set data | Basic lighting module immediately turns off |
| Daytime | Less than set data | Delayed turn-on of basic lighting module |
The set data in table 1 are the ambient light threshold values after testing. The condition that the lighting module is turned on in a delayed mode is the weather of rainy days in the daytime. The delay time is adjustable, and the delay starting time is set to avoid unnecessary starting of the system caused by dark sky in a very short time. And if the natural color is dark for a certain time, the basic lighting module is started.
The first lighting module in this embodiment, when turned on, will provide the environment with basic lighting that meets the current domestic minimum illumination requirement, and the first lighting module supplements and reinforces the basic lighting.
In the running process of the whole set of system, the ambient light detection module continuously and periodically detects the photosensitive data, and the master control module periodically corrects the ambient light critical value of system start and the time control switch data in the time module according to the detection data.
The manual control mode in this embodiment is mainly used for lighting control in emergency, for example, when the automatic mode fails due to a fault or the light is required to be forcibly turned on. When a user needs to start the manual control, the mode switch is only required to be switched to be manual, and then the master control module receives the signal sent back by the mode switch. The overall control module will then stop receiving signals from the time module, the ambient light detection module and the obstacle sensing module, i.e. these modules will be disabled altogether. The manual control mode in this embodiment would provide two illumination modes for manual selection by the user. The first is the base mode, which provides the same illumination as the base illumination in the automatic mode. The second is a high intensity mode in which the base mode light remains on and all the auxiliary lighting banks will be forced on. The auxiliary lighting will not be lit up again regionally, but entirely. In this brightness mode, city streets and courtyards will be maximally supported for lighting. The user only needs to use and dial illuminance adjustment switch, and then the switch can be with high/low level signal transfer to total control module, and then total control module can be based on the signal that receives and send corresponding illumination start mode to the illumination module, and wherein high level signal is the fundamental mode, and low level signal is the hi-lite mode.
In practical application, the lighting control system of the embodiment preferably adopts a high-pressure sodium lamp or a light-emitting diode as a light source; the protection grade of the lamp is not lower than IP 65; the overhanging length of the lamp is not more than 1/4 of the installation height, and the elevation angle of the lamp is not more than 15 degrees; the included angle between the maximum light intensity aiming direction of the lamp and the vertical line is not more than 65 degrees; the urban road lighting power load is not lower than three levels; the road illumination is preferably powered by a special transformer for the street lamp through an underground cable, and has short-circuit protection and overload protection; TT system or TN-S system is suitable for grounding; for lighting control, the time for turning on and off the light of the road lighting is reasonably determined according to the geographical position of the area and seasonal variation, and a control mode combining light control and time control which is corrected according to sky brightness variation is preferably adopted; the centralized lighting control system and the remote control terminal have a control function of automatically switching on and off the street lamp and a manual emergency control function under the condition of communication interruption; natural light level when the road lighting is turned on and off: the expressway and the main trunk are preferably 30lx, the secondary trunk and the finger way are preferably 20lx, after energy-saving adjustment, the expressway, the main trunk and the secondary trunk are not lower than 10lx, and the branch is not lower than 8 lx.
