In a certain illumination time period of the illumination light group, the personnel sensor is activated, and the timing module is triggered to reset the illumination duration of the corresponding time period.
Specifically, in a control section process of controlling the lighting lamp set to turn on the lighting in the adjustment mode, the method comprises the following steps:
firstly, the lighting lamp group is maintained in a closed state, and when the sensor group monitors that the personnel activities are activated, an adjustment mode is started and a control section is entered; in the control section, a judging value p is set to represent the number of times the sensor group is activated by the triggering of personnel activities; according to the judgment level P which the judgment value P falls into n Selecting a time period T corresponding to the time period T n Illuminating the lamp group and maintaining T n The set time period t n The method comprises the steps of carrying out a first treatment on the surface of the During the period of illumination maintaining of the illumination lamp group, the judgment value P is increased by 1 every time personnel activity is monitored, and then the judgment level P in which the updated judgment value P falls is determined n ' simultaneously resetting the illumination time t of the illumination lamp group n 'A'; when the sensor group is greater than T n And if no personnel activities are detected within the time period set by max, ending the control section, and turning off the lighting lamp group.
In this embodiment, the frequency determination level is gradually increased, where the level value corresponds to the number of times the personnel sensor counted by the counting module is activated.
Thus, in an implementation, all lamps are first maintained in an unmanned mode, and a control segment is entered when a person sensor is activated; in this control section, starting at the point in time when the person sensor is activated, all lamps are switched to the highlight mode, and the highlight mode t is maintained 1 A time period, within T seconds of the duration of the highlight mode, each time the person sensor is activated, causing the highlight mode to reset the illumination time period; each time the person sensor is activated, a judgment value P is calculated to determine a judgment level P of the person activity frequency n And updates the reset illumination time to P n Corresponding T n Represented t n Duration of time.
Further, in the control section process of the lighting lamp set, setting the time interval between two adjacent personnel activities monitored by the sensor group as X, and calculating a judgment value p:
when X < the current time period t n Updating the judgment value to be p+1, and calculating according to a normal calculation method of the judgment value p, wherein the judgment value is indicated that the degree of the interval between the entrance and the exit of the personnel is not changed excessively at the moment;
when X is greater than or equal to the current time period t n Updating the judgment value p to be larger than X and the time t closest to X n Is represented by a period T n Corresponding P n The minimum level value of the above table indicates that the interval between the person entering and exiting is greater than the accumulated value p in the method, and the person entering and exiting is still likely to need to enter and exit frequently although the interval between the person entering and exiting is longer, but the illumination time is not long enough because the value p is not accumulated, so that the value p needs to be quickly adjusted to the corresponding state.
In the present embodiment, when X > T n max, which indicates that the control segment end condition has been entered, so this condition need not be considered; for example, when the person returns in a warehouse scene, the possibility is higher, and when the person returns in a larger time interval, the number of times of activating the person sensor is increased, but the judgment value is gradually reduced, the judgment level of the frequency is reduced, so that the illumination duration is more suitable for the person activity state of the current scene, and the electric energy is saved.
As a preferred embodiment of the present invention, when the adjustment mode is turned on, the illumination lamp group is controlled to be turned on or off for a long period of time after the adjustment mode is turned on; specifically, when the adjustment mode is started, setting a judgment value P as 0, and when a first control section is entered, setting an initial value of the judgment value P as 1, wherein the corresponding frequency judgment level and time period are respectively P1 and T1;
in any subsequent control section, the initial values of the judgment value p and the time period T are determined by adopting an attenuation algorithm, and the method comprises the following steps:
the initial judgment value p in any subsequent control section is recorded as p m The time period corresponding to the frequency judgment level is T m The method comprises the steps of carrying out a first treatment on the surface of the Let the judgment value at the end of the previous control section be p m-1 The value of the time period is T m-1 ;
