Description

Technical Field

[0001] The utility model relates to a lighting control system, in particular to a garden landscape lighting control system Background Art

[0002] With the popularization of the Internet of Things and industrial intelligence, related intelligent technologies have gradually evolved from the pure electronic information field to other fields, including the field of garden landscape. In the past, in the field of garden landscape, more attention was paid to the spatial layout of the landscape, gardening technology, color matching, seasonal matching, architectural planning, ecological restoration, the habits and growth laws of plants and flowers themselves, etc. What it brings to people is the aesthetic enjoyment of nature. Nevertheless, in today's cities, whether it is streets or residential areas, people's demand for garden landscapes is also changing. For example, at night, we can't see the rich and diverse garden colors, but only the monotonous street lights on both sides of the road. In cities, especially big cities, the pace of life is getting faster and faster, so that there is no time to appreciate the beautiful scenery around us during the day. We can only choose to take a walk at night to exercise, and then we can't see the effect of garden landscape at night. Therefore, it is necessary to enrich the garden landscape at night to meet people's growing aesthetic needs for garden landscapes at night. Based on this, many night lights are installed in many city streets or communities, including spotlights mounted next to plants, ground lamps buried in the middle of the grass, and light strips hanging on trees. But they all look very monotonous and easy to get aesthetic fatigue. Therefore, it is necessary to design a landscape lighting system that can provide people with a rich and diverse aesthetic experience.

[0003] The Chinese utility model with publication number CN207720475U discloses a control circuit for lighting up 16 street lamps in turn and in a cycle, comprising a pulse signal module, a counter module, a decoder module, 16 light emitting diodes and a power supply module for providing working voltage for the entire control circuit, wherein the pulse signal output end of the pulse signal module is connected to the input end of the counter module, the output end of the counter module is connected to the input end of the decoder module, and the output end of the decoder module is respectively connected to the 16 light emitting diodes. The pulse signal module generates a pulse signal and transmits it to the counter module, which outputs the signal to the decoder module after processing, and the decoder module outputs 16 control signals to the 16 light emitting diodes after decoding, and the 16 light emitting diodes are respectively lit up in turn and in a cycle. The utility model has a simple circuit structure, is easy to implement, is easy to adjust the flashing lighting cycle of the lamp, is flexible to use, has high reliability, and is relatively low in cost.

[0004] However, the above control circuit can only change the light at a fixed period according to the signal output by the pulse signal module. When the flow of people changes, the light cannot be changed according to the change of the flow of people. In other words, the light cannot be changed every time someone passes by. When there are no pedestrians for a long time, the above control circuit cannot automatically stop the light, which wastes energy. Summary of the invention

[0005] Purpose of the utility model: The purpose of the utility model is to provide a garden landscape light control system that switches the light every time someone passes by and saves energy.

[0006] Technical solution: The garden landscape lamp control system described in the utility model includes a plurality of lamps, each lamp is connected to a different output end of a decoder, the input end of the decoder is connected to a first counter, the clock input end of the first counter is connected to a sensor for sending a signal to the counter when someone passes by, the reset end of the first counter is connected to any output end of the second counter; the clock input end of the second counter is connected to an oscillator, and the reset end is connected to the sensor; the output end of the decoder that outputs a high level is unloaded when the first counter counts to zero.

[0007] Based on the above technical solution, the sensor can sense the passage of pedestrians. When a human body approaches, it will output a signal, which is then used as a clock pulse signal to the clock input end of the first counter, and the first counter will count plus 1. Then, after being decoded by the decoder, the output end of the decoder corresponding to the serial number of the accumulated value of the first counter will be set high, and then the lamp with the corresponding serial number will be lit; the oscillator will continue to input signals to the second counter, so that the count of the second counter continues to increase. When the accumulation reaches a specific value, the output end of the second counter connected to the reset end of the first counter will output a high level, so that the count of the first counter is reset to zero, and then the decoder outputs a low level except for the output end that is not connected to the lamp, all lamps stop working and enter a state similar to standby, thereby achieving low power consumption; when someone passes by, the sensor will also synchronously input a signal to the reset end of the second counter to reset the count of the second counter, so that the reset state of the first counter will not be triggered when someone passes by.

[0008] Preferably, the reset terminal of the first counter is connected to the output terminal between the head end and the tail end of the second counter.

[0009] Preferably, the sensor is a pyroelectric sensor.

[0010] The use of pyroelectric sensors can accurately determine whether a person is passing by rather than an inanimate object through infrared sensing, and the cost is low.

[0011] Preferably, the sensor is a microwave radar sensor.

[0012] The use of microwave radar sensors can more accurately sense human movement and achieve better detection results.

[0013] Preferably, the sensor is an ultrasonic sensor.

[0014] Preferably, the lamp is an LED light strip.

[0015] The lamp adopts LED light strip to make it have more color changes and increase the viewing experience.

[0016] Preferably, the LED light strip comprises a plurality of LEDs of the same or different colors.

[0017] Beneficial effect: Compared with the prior art, the utility model has the following beneficial effects: by setting a sensor that senses the passage of human body, the light can be changed when a pedestrian passes by; and by combining the oscillator and the second timer with the sensor, the light can be stopped when no one passes by at the set time, thus saving energy. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Figure 1 It is the overall circuit diagram of the utility model;

[0019] Figure 2 It is a schematic diagram of the partial structure of three LED light strips. DETAILED DESCRIPTION

[0020] As shown in the figure, the garden landscape lamp control system provided by the utility model includes a plurality of lamps 6, each lamp 6 is connected to a different output end of a decoder 5, the input end of the decoder 5 is connected to a first counter 2, the clock input end of the first counter 2 is connected to a sensor 1 for sending a signal to the first counter when someone passes by, the reset end of the first counter 2 is connected to any output end of the second counter 3; the clock input end of the second counter 3 is connected to an oscillator 4, and the reset end of the second counter 3 is connected to the sensor 1; the output end of the decoder 5 that outputs a high level is unloaded when the first counter 2 counts to zero.

[0021] The sensor 1 can be a pyroelectric sensor, a microwave radar sensor or an ultrasonic sensor, etc., which can sense the passage of a human body and send out a signal accordingly; the sensor 1 is installed at the entrance of a garden landscape belt or in the middle of landscape plants. When a human body approaches, it will output a signal, which is simultaneously input into the clock input terminal of the first timer 2 and the control device.

[0022] The count output terminal Q of the first counter 2 0 ~Q m Connected to the data input terminal A of the decoder 5 0 ~A m, where m is a non-zero natural number, and the first timer 2 starts to accumulate values ​​upon receiving a signal.

[0023] The lamps 6 are all provided with switches, and the decoder 5 includes a decode output terminal Y 0 ~Y n , where Y 1 ~Y n Connect the switches K of the lamps 6 1 ~K n , where n is a non-zero natural number, from the output terminal Y 1 ~Y n Control switch K 1 ~K n The switch is closed when the output terminal outputs a high level, otherwise it is disconnected; 0 The output end is not connected to lamp 6 because when the first counter 2 is reset, the output end will output a high level. In order to achieve energy-saving effects, it is necessary to ensure that all lamps 6 are not lit at this time, so the output end cannot be connected to lamp 6; the decoder 5 determines that the corresponding decoding output end outputs a high level based on the accumulated value of the first counter 2, and the switch connected to the output end is closed, thereby lighting the lamp 6.

[0024] A plurality of lamps 6 form a lamp array, and the lamps 6 are LED light strips. The LED light strips include a plurality of LEDs of the same or different colors. The color configurations of different lamps 6 can be the same or different, and the differences can increase the ornamental value. When there are LEDs of multiple colors in the LED light strip, the LEDs of the same color can be arranged in sequence or at intervals, that is, a different-color LED is arranged between the LEDs of the same color. It can be customized according to specific needs or ideas. The lamp array is installed on trees or other landscape plants.

[0025] Any output terminal of the second counter 3 is connected to the reset terminal of the first counter 2 .

[0026] The oscillator 4 is an input signal for the second counter 3, and the second counter 3 accumulates values ​​according to the signal. The second counter 3 includes a plurality of output terminals, and the output terminal Q connected to the reset terminal of the first counter 2 k Not at the head end or the tail end. Of course, if the time interval for clearing the first counter 2 is required to be very short or very long, it can also be connected to the output end of the head end or the tail end.

[0027] When someone passes by, the sensor 1 will input a signal to the reset end of the second counter 3 to reset it, thereby preventing the output end of the second counter 3 connected to the first counter 2 from triggering a high level due to the accumulated value and clearing the first counter 2; the reset of the first timer 2 can only be triggered when no one passes by and the set time is reached.

[0028] By changing the position of the output end of the first counter 2 connected to the reset end of the second counter 3, or changing the signal output frequency of the oscillator 4, the time after no one is present can be adjusted to reset the first counter 2, so that all the lights 6 stop working and energy is saved.

[0029] The working principle of the utility model is as follows:

[0030] First, the system is powered on, the two counters are initially cleared, and the switches of all lights 6 are turned off, which is equivalent to the initial state being the low power consumption mode; the first counter 2 waits for a signal, and the second counter 3 automatically starts counting upward from zero under the drive of the oscillator 4.

[0031] Sensor 1 monitors whether someone is approaching or passing by. If so, it outputs a signal, which makes the first counter 2 add 1, and the switch of the light array is changed; at the same time, the signal also resets the second counter 3 and starts counting from zero again; if no one approaches or passes by for a long time, the output terminal Q of the second counter 3 is k It will become a high level, thereby clearing the first counter 2, turning off all light switches and entering a low power consumption mode.
