Detailed Description

Example 1

As shown in fig. 1, the system includes a power source and further includes a lighting subsystem including an outdoor lighting subsystem including a field lighting fixture and a roadway lighting fixture and an indoor lighting subsystem.

The field lighting device comprises a light control switch KM1 connected with the power supply and an LED lamp LED1 connected with the light control switch KM1 in series. Therefore, the floodlights in the strip yard, such as the crane headlights, can be automatically turned off under the condition that the general brake is closed and enough light is provided in the daytime, so that the electricity is saved. And the LED is a photoelectric direct conversion element, has high photoelectric conversion efficiency, has no heat energy conversion process, and only has small heat effect generated by small internal resistance of current in the PN pole of the LED. Therefore, the LED is the most ideal energy-saving luminous body at present, and the power consumption is greatly saved compared with the use of the traditional lamp (such as a dysprosium lamp commonly used in a pylon). The model of the light-operated switch KM1 can be 5WLED 3528.

The road lighting device comprises a solar LED street light LED2 connected to the power supply. In the daytime, under the control of the controller of the solar LED street lamp, the solar panel absorbs solar light and converts the solar light into electric energy through the irradiation of sunlight, the electric energy is charged to the storage battery pack, and the storage battery pack provides electric power to supply power to the LED lamp light source at night, so that the lighting function is realized. After the arrangement, the on-site road lighting can greatly reduce the power consumption and even realize self-sufficient zero power consumption.

The indoor lighting subsystem includes windowed and windowless lighting fixtures comprising a timed switch a (identified as KT1 in fig. 1) connected with the power supply and an LED bulb LED3 in series with the timed switch a. Therefore, the on and off of the LED bulb 3 can be controlled by setting the on and off control time period of the time control switch A, and the LED bulb LED3 can be automatically turned off in the invalid time period, so that the aim of saving energy is fulfilled.

Further, the window illumination device may be divided into a first window illumination device and a second window illumination device, and the on/off state of the time switch a of the first window illumination device and the on/off state of the time switch a of the second window illumination device are set to be opposite. The first windowed lighting device can be arranged in an office place, the second windowed lighting device is arranged in a staff dormitory, the on-off control time periods of the time control switch A of the first windowed lighting device and the second windowed lighting device are set to be opposite, so that the illumination of the office place and the lighting of the staff dormitory form a complementary time period, the illumination of the dormitory can be automatically turned off when the person goes to work, the illumination of the office can be automatically turned off after the person goes to work, and therefore electric power is reasonably saved.

The windowless lighting device comprises a microwave radar sensing switch KM2 connected with the power supply and an LED strip LED4 connected with the microwave radar sensing switch KM2 in series. The model of the microwave radar inductive switch KM2 can adopt AP-RSK/WP.

Because the windowless room lighting device is usually applied to closed spaces such as garages, main building basements, staircases and elevator rooms, the windowless room lighting device is in a dark state no matter day or night, and the microwave radar sensing switch KM2 can sense nearby active personnel, so that the windowless room lighting device can provide lighting when people are in existence, and automatically turns off the lamp after no people are in existence, thereby saving electric power. The LED strip is used because the strip-shaped LEDs are easy to lay. Because the basement is designed and constructed in such occasions without considering the aesthetic property, pipelines and beam frames are usually densely distributed at the top of the basement, the installation of the conventional lamp is relatively inconvenient, the LED lamp strip is light in weight, soft and convenient to lay, and can be effectively fixed by locally bonding the irregular top, so that the LED lamp strip can be laid on the irregular top surface in a fitting manner and can also be laid across the space according to the situation. And the LED lamp belt is equivalent to self-laying wires when being laid due to the belt-shaped appearance, so that the working procedures are saved. And because it lays in the space of total blackness for the total length of lamp area all can effectively illuminate the exterior space, does not have the problem of extravagant lighting apparatus.

This system still includes domestic power subsystem, domestic power subsystem include with water heater R1 that the power is connected, water heater R1 is the air can the water heater. The air energy water heater can absorb low-temperature heat in air, the low-temperature heat is gasified through a fluorine medium, the fluorine medium is compressed by the compressor and then is pressurized and heated, and the water temperature is heated through the compressed high-temperature heat. The air energy water heater has the characteristics of high efficiency and energy conservation, can produce the same amount of hot water which is 4-6 times that of the common electric water heater, has high utilization efficiency and greatly reduces the electric energy consumption. In addition, the air energy water heater does not need an electric heating element to be in direct contact with water, so that the danger of electric leakage of the electric water heater is avoided.

In addition, the household power subsystem further comprises an indoor air conditioner M1 connected with the power supply, and the indoor air conditioner is connected with a time control switch B (marked as KT2 in figure 1) in series. The time control switch B has a function similar to the time control switch A, and the indoor air conditioner M1 can be started and stopped in the working period and the working period through setting, so that electricity is saved.

In addition, the system also comprises an electric subsystem for operation, wherein the electric subsystem for operation comprises a high-pressure water pump M2 for supplying water for construction operation, and the high-pressure water pump M2 is a variable-frequency high-pressure water pump. The variable frequency water pump uses a variable frequency motor, the frequency can be adjusted, the variable frequency motor adjusts the flow rate by adjusting the rotating speed, so that the power of the high pressure water pump can be adjusted by using a frequency converter according to the water consumption, the energy-saving purpose is achieved, the starting current is small, and the maintenance workload is small. A large amount of construction water is required to be pumped to the construction surface of a high-rise building every day in a construction site, and electric energy is greatly saved due to the use of the variable frequency water pump.

Example 2

As shown in fig. 2, the field lighting device further includes an air switch QF1 and a leakage protector QF2, and the air switch QF1, the leakage protector QF2, the photoswitch KM1 and the LED lamp LED1 are connected in series in the current direction. The model of the air switch QF1 can adopt DZ20-40T, and the model of the leakage protector QF2 adopts GM20 LE-40/290.

Because the air switch QF1 not only functions as the main brake of the device, but also is relatively reliable, durable and long-lived, it is arranged at the foremost end of the live wire (i.e. the L-wire in fig. 2), so that it is convenient for the replacement and maintenance of the following wearing parts after being turned off. The leakage protector QF2 can prevent accidental electric shock, the protection range of the leakage protector QF2 can be expanded as much as possible by arranging the leakage protector QF2 immediately behind the air switch QF1, and the related circuits of the light-operated switch KM1 and the LED1 of the LED lamp at the downstream of the current are all protected by the leakage protector QF2, so that the leakage phenomenon of related devices is prevented.

As shown in fig. 3, the windowless lighting device further includes an air switch QF3 and a leakage protector QF4, where the air switch QF3, the leakage protector QF4, the microwave radar induction switch KM2, and the LED strip LED4 are sequentially connected in series along a current direction. And may further comprise a voice-operated switch KM3, wherein the voice-operated switch KM3 is connected in parallel with the microwave radar sensing switch KM 2. The air switch QF3 and the leakage protector QF4 can be of the type of the air switch QF1 and the leakage protector QF2, and the sound control switch KM3 can be of the type of MRT 103-M70-3. The effect of the connection structure is that besides the effect of the field lighting device, the sound control switch KM3 is provided, so that the adaptability of the windowless lighting device is better. Because the structure of the closed space such as a basement and a staircase is relatively narrow and tortuous, the closed space is not as wide and smooth as the closed space such as an underground garage, the induction of the microwave radar inductive switch KM2 is hindered, and the detection range is reduced. However, since the construction operation usually accompanies with larger noise, especially in a narrow and tortuous space, the sound has the effect of reverberation diffusion, not only enough sound intensity is maintained, but also the sound lasts for a longer time, so that the effect of sound detection is better at the moment. The sound control switch KM3 is connected with the microwave radar induction KM2 switch in parallel, so that the sound control switch KM3 and the microwave radar induction KM2 switch can both play a role, the adaptability of equipment can be improved, and the related temporary control cabinet can be recycled in the next construction operation, so that people do not need to distinguish application occasions intentionally, and the use is convenient.

After the arrangement, taking basement illumination of a test project as an example, the underground has two floors, the area of each floor of a main floor is 2000m2, and the area of each floor of an auxiliary floor is 1000m 2. Each layer of walkway of the main building is divided into a north side and a south side, the north side and the south side of each layer of walkway are about 250m long, 1kW dysprosium lamps are installed at the tops of the walkways, and 10 walkways are installed on each layer. The attached building is provided with 5 pieces of the plants on each floor. A total of 30 dysprosium lamps are installed in the basement. The electricity consumption per hour is 30 kW. If no construction is carried out from 7 pm to 6 pm every morning, and the number of hours is 11, the power is saved by 30 × 11 — 330kWh every day. The power can be saved by 330 × 30 ═ 9900 degrees in 30 days per month, and the power can be saved by 9900 yuan per degree, and by 1.0 yuan per month. The common traditional lamp is changed into the LED energy-saving lamp, so that the energy is saved by 5/6, the electricity charge can be saved by 30 multiplied by 13 multiplied by 30 multiplied by 1 multiplied by 5/6=9750 yuan each month, and the total saving is 9900+9750=19650 yuan. The cost of components of the control electric circuit is less than 2000 yuan, and if the secondary structure construction, installation construction and decoration construction stages after the main structure is finished are counted in 5 months, electricity can be saved in the basement lighting 19650 x 5-2000-98050 yuan. And the control circuit distribution box can be continuously used in the next project, and can continuously generate certain economic benefits for enterprises.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
