The embodiment of the present application provides a direct current lighting control system 10, including: a rectifier 100, a time detector 200, a human body detector 300, and a controller 400.

The time detector 200 may be a common clock, a clock circuit, a clock chip, or the like, or may be any other device having a time detection function, and this embodiment is not limited at all, and may be specifically set according to actual needs, and only needs to satisfy a function of detecting the current time and outputting a time signal.

The human body detector 300 is configured to detect whether a person enters the substation 30, and output a human body signal, where the human body signal is used to indicate whether a person enters the substation 30. For example, when the intensity of the human body signal is not zero or exceeds a certain threshold, it is verified that a person enters the substation 30, and when the intensity of the human body signal is zero or is lower than a certain threshold, it is verified that no person enters the substation 30.

The human body detector 300 is not limited in any way, and may be specifically selected according to actual conditions, and only needs to satisfy the function of detecting whether a person enters the substation 30 and outputting a human body signal.

In the second case, when the intensity of the human body signal is not zero or exceeds a certain threshold, it is proved that someone enters the substation 30 at the present time, the controller 400 controls the rectifier 100 to operate, and outputs a direct current with a second intensity to be used by the lighting device 21, so that the lighting device 21 operates. In the third case, when the time signal is in the night time zone and the intensity of the human body signal is not 0 or exceeds a certain threshold, it is proved that a person enters the substation 30 at night, the controller 400 controls the rectifier 100 to operate, and outputs a direct current with a third intensity for the lighting device 21 to operate, and the lighting device 21 operates. The lighting device 21 generates different illumination at different intensities of voltage to provide different intensities of illumination under different conditions.

The working principle of the dc lighting control system 10 provided in this embodiment is as follows:

the dc illumination control system 10 provided in this embodiment includes a rectifier 100, a time detector 200, a human body detector 300, and a controller 400. The time detector 200 detects the time of the current time in real time to determine whether the current time is day or night, the human body detector 300 is used for detecting whether a person enters the substation 30, the time detector 200 and the human body detector 300 are respectively in signal connection with the controller 400, and the controller 400 controls the rectifier 100 to work according to the time signal and the human body signal. When the time signal is in the daytime, the controller 400 controls the rectifier 100 not to work, and when the time signal is at night and the human body signal indicates that a person enters the transformer substation 30, the controller 400 controls the rectifier 100 to work, so that the lighting device 21 is prevented from lighting or stroboscopic for a long time.

The dc illumination control system 10 provided in this embodiment includes a rectifier 100, a time detector 200, a human body detector 300, and a controller 400. In this embodiment, the dc lighting control system 10 is provided with the time detector 200 and the human body detector 300 at the same time, and simultaneously determines whether the rectifier 100 needs to be started or not by the time signal of the time detector 200 and the human body signal of the human body detector 300, that is, controls whether to start the lighting device 21 for lighting, so as to avoid the technical problem that the control mode effect of the lighting system of the substation 30 is poor at present due to the stroboscopic effect of the lighting device 21, and achieve the technical effect of improving the control effect of the lighting system of the substation 30.

The clock chip 210 is in signal connection with an input end of the controller 400, and the clock chip 210 is used for determining the specific time of the current time, so that the controller 400 can determine whether the specific time period of the current time is in the day or at night according to the time signal output by the clock chip 210. If the current time is in the night time interval, the controller 400 controls the rectifier 100 to operate to output a voltage with a certain intensity, so that the lighting device 21 operates to provide illumination for the staff entering the substation 30. The clock chip 210 may be internal or external, and this embodiment is not limited at all, and may be specifically selected according to an actual situation, and only needs to satisfy a function of determining a specific time at the current time.

For example, when the clock chip 210 determines that the current time is in the daytime, but the light sensor 220 detects that the light at the moment is weak, the rectifier 100 is continuously controlled to be started to output a voltage with a certain intensity, so that the lighting device 21 operates to provide illumination for workers entering the substation 30. The optical sensor 220 may also be a visible light sensor of other types, which is not specifically limited in this embodiment, and may be specifically selected according to actual conditions, and only needs to satisfy the function of detecting the ambient light of the substation 30.

Referring to fig. 3, in one embodiment, the human body detector 300 includes: an infrared sensor 310 and a sound sensor 320.

The infrared sensor 310 is in signal connection with an input end of the controller 400, the infrared sensor 310 is used for detecting whether a person enters the substation 30, and when the infrared sensor 310 detects that a person enters the substation 30, the controller 400 controls the rectifier 100 to be started so as to output a voltage with a certain intensity, so that the lighting device 21 works and provides illumination for workers entering the substation 30. The number of the infrared sensors 310 may be multiple, and the multiple infrared sensors 310 are respectively disposed at different positions of the substation 30 to detect the activity of the human body in the substation 30 in multiple directions and multiple angles. In this embodiment, the type, the number, and the like of the infrared sensors 310 are not limited at all, and specific selection or equipment may be selected according to actual conditions, and only the function of detecting whether a person enters the substation 30 may be satisfied.

The sound sensor 320 is in signal connection with an input end of the controller 400, the sound sensor 320 is used for detecting whether a person enters the transformer substation 30, when the person enters the transformer substation 30 to move, and when the moving sound exceeds a certain threshold value, the sound sensor 320 sends a sound signal to the controller 400, the controller 400 controls the rectifier 100 to be started so as to output voltage with certain intensity, the lighting device 21 works, and illumination is provided for workers entering the transformer substation 30. The number of the sound sensors 320 may be one or multiple, and the sound sensors 320 are respectively disposed at different positions of the substation 30 to collect sound signals of different positions of the substation 30, so as to further determine whether a person enters the substation 30. In this embodiment, the number, types, and the like of the sound sensors 320 are not limited at all, and may be specifically selected or set according to actual conditions, and only the function of detecting whether a person enters the substation 30 may be satisfied. The infrared sensor 310 and the sound sensor 320 work together to determine whether people exist in the substation 30 currently from two dimensions of light signals and sound signals, and reliability is higher.

In one embodiment, the controller 400 is configured to control the rectifier 100 to stop working if the time signal is in a preset sufficient illumination time period.

The time signal is detected by the time detector 200, the controller 400 is in signal connection with the time detector 200, when the time signal is in a preset time zone with sufficient illumination, such as 8-17 o 'clock per day, and at the moment in the daytime, the illumination is sufficient, the controller 400 controls the rectifier 100 to stop working at 8-17 o' clock per day to save electric energy. The preset sufficient illumination time zone may be specifically set according to actual conditions, for example, 7 to 18 points, 8 to 17 points, and the like, which is not specifically limited in this embodiment and may be specifically set according to actual conditions.

In one embodiment, the controller 400 is further configured to perform the following control actions when the time signal is night:

and when the time signal is in a preset overhauling time range and the intensity of the human body signal exceeds the preset threshold value, controlling the rectifier 100 to output direct current with first intensity. The overhaul time range refers to a time period in which a worker needs to overhaul equipment in the substation 30, for example, 2 to 3 points in the morning each day. In the maintenance stage, the required illumination is strongest, when the current moment is within the preset maintenance time range, the rectifier 100 does not act, and only when the current moment is within the preset maintenance time and a person is detected to enter the transformer substation 30, the controller 400 controls the rectifier 100 to work and outputs direct current with first intensity, so that the lighting equipment 21 works to provide illumination for workers entering the transformer substation 30, the lighting equipment 21 works according to actual needs, and electric energy is saved.

And when the time signal is in a preset patrol time range and the intensity of the human body signal exceeds a preset threshold value, controlling the rectifier 100 to output direct current with second intensity. The patrol time range is a time range in which the transformer substation 30 equipment needs to be patrolled, the requirement on illumination is not high, only the basic illumination requirement of patrol workers needs to be met, and too strong illumination is not needed, so that the second intensity is smaller than the first intensity, when the time signal is in the preset patrol time range and the intensity of the human body signal exceeds a preset threshold value, the rectifier 100 is controlled to output direct current with the intensity smaller than the first intensity, and electric energy is saved.

And when the time signal is not in the preset patrol time range and the preset overhaul time range and the human body signal does not exceed the preset threshold value, controlling the rectifier 100 to output direct current with third intensity, wherein the third intensity is smaller than the second intensity. That is to say, at the present moment, although the human body detector 300 is in the preset patrol time range or the preset overhaul time range, it does not detect that someone enters the substation 30, and therefore, only basic illumination needs to be provided at the moment, so as to save electric energy.
