Description

Technical Field

[0001] The present invention relates to the field of energy-saving technology, and in particular to an intelligent building energy Internet of Things device and an integration method thereof. Background Art

[0002] Wind energy and solar energy have been widely promoted due to their energy conservation and environmental protection, and are currently also used in building-related areas. The existing building application of solar energy and wind power generation methods generally involves storing the electricity generated by solar panels under sunlight and the electricity generated by wind turbines under wind in a battery pack. After the battery pack has a certain capacity and voltage, the control system disconnects the mains power and the battery pack supplies power to the electrical equipment in the building through the power inverter. The above method has a problem that, due to the influence of the environment, the sunlight intensity cannot be high at all times, and the wind force cannot always be strong, that is, the voltage of the electricity generated by the two fluctuates, and the charging voltage of the battery pack is generally based on the rated power generation voltage of the generator. In this way, when the wind force is small, the electricity generated by the wind turbine and the electricity generated by the solar panel are too small, because the voltage is too low, the storage group cannot be charged, that is, wind energy and solar energy cannot be effectively utilized. In addition, the existing buildings cannot utilize the hydraulic power generated by running water, so there are certain limitations. Summary of the invention

[0003] In order to overcome the problem that the existing buildings cannot effectively utilize the electricity generated in low light and low wind conditions, and cannot effectively utilize the electricity generated by indoor tap water pipes due to technical limitations when utilizing wind energy and solar energy, the present invention provides a plurality of water flow generators installed in series in the tap water pipes, which fully utilize the electricity generated by the flow of tap water. Every two solar panels, every two wind generators, and every two water flow generators are grouped together. Under the action of relevant circuits, when the voltage of the generator is lower than a certain level, the two generators are connected in series to charge a battery pack. When the voltage is higher than a certain level, the two generators are connected in parallel to charge the battery pack. In this way, not only the electricity generated by the generators in low water flow, low wind force, and low light conditions is effectively utilized, but also water flow series power generation is realized, thereby improving the power generation efficiency.

[0019] Figure 1 , 2As shown, in the control circuit supporting each group of two solar panels G1 and G2 (or each group of two wind turbines M1 and M2, each group of two water flow generators MS1 and MS2), when the external sunlight is weak (or the wind is weak, the water flow is small), the voltage of the electric energy generated by the solar panels G1 and G2 (or each group of two wind turbines M1 and M2, each group of two water flow generators MS1 and MS2) is lower than the rated value (for example, the power generation voltage of the solar panel or wind turbine, water flow generator is 12V, and the voltage is only 7V at this moment), so the power output from the positive electrode of the first solar panel G1 (or the first wind turbine M1, the first water flow generator MS1) is reduced by the adjustable resistor RP (or RP1, RP2) and the current is limited, and then the base of the NPN transistor Q1 (or Q3, Q5) is lower than 0.7V, and the Darlington transistor composed of the NPN transistors Q1 and Q2 (or Q3 and Q4, or Q5 and Q6) is cut off, and the relays K, K1 (or K2, K3 and K4, K5) remains in a power-off state; in this way, the positive electrode of the first solar panel G1 (or the first wind turbine M1, the first water flow generator MS1) is unidirectionally conducted through the diode VD1 (or VD3, VD5) and directly enters the positive electrode of the battery pack G, the negative electrode of the first solar panel G1 (or the first wind turbine M1, the first water flow generator MS1) is connected to the positive electrode of the second solar panel G2 (or the second wind turbine M2, the second water flow generator MS2) via the control power input terminal and the normally closed contact terminal of the relay K (or K2, K4), the first control power input terminal and the first normally closed contact terminal of the relay K1 (or K3, K5), and the negative electrode of the second solar panel G2 (or the second wind turbine M2, the second water flow generator MS2) is directly unidirectionally conducted through the diode VD2 (or VD4, VD6) and enters the negative electrode of the battery pack G to charge the battery. Since the two solar panels G1 and G2 (or the two wind turbines M1 and M2, and the two water flow generators MS1 and MS2) are in series connection at this moment, the battery pack G can still be charged when the power generation capacity of the solar panels G1 and G2 (or the two wind turbines M1 and M2, and the two water flow generators MS1 and MS2) is only half, so the low voltage generated by low light (or low wind force, low water flow) is effectively utilized to achieve energy saving (for example, the nominal voltage of the battery pack G is 12V, so the low voltage generated by a single solar panel (or a single water flow generator, a single wind turbine) cannot be fully utilized. Even if multiple solar panels (or multiple water flow generators, multiple wind turbines) used in the prior art are connected in series to supply power, the voltage after the series connection is close to the voltage of the battery pack, so the low voltage generated by low light (or low wind force, low water flow) cannot be utilized at all.

[0020] Figure 1 , 2As shown, in the control circuit supporting each group of two solar panels G1 and G2 (or each group of two wind turbines M1 and M2, each group of two water flow generators MS1 and MS2), when the external sunlight is strong (or the wind is strong, the water flow is strong), the voltage of the electric energy emitted by each single solar panel G1 and G2 (or each group of two wind turbines M1 and M2, each group of two water flow generators MS1 and MS2) is higher than the rated value (for example, the power generation voltage of the solar panel or wind turbine, water flow generator is 12V, and at this moment it is higher than 12V, and the no-load voltage of the generator is generally higher than the voltage of the battery pack by 20%, so that the battery pack can be effectively charged), so that the power output of the positive electrode of the first solar panel G1 (or the first wind turbine M1, the first water flow generator MS1) is reduced in voltage and limited in current by the adjustable resistor RP (or RP1, RP2), and then enters the base of the NPN transistor Q1 (or Q3, Q5) and the voltage is higher than 0 .7V, the Darlington transistor composed of NPN transistors Q1 and Q2 (or Q3 and Q4, Q5 and Q6) is turned on, and relays K and K1 (or K2 and K3, K4 and K5) are energized and attracted. After relay K (or K2 and K4) is energized and attracted, its control power input terminal and normally closed contact terminal are opened. After relay K1 (or K3 and K5) is energized and attracted, its three control power input terminals and three normally open contact terminals are respectively closed, and the three control power input terminals and three normally closed contact terminals are respectively opened. In this way, the positive electrode of the first solar cell panel G1 (or the first wind turbine M1, the first water flow generator MS1) will be connected to the positive electrode of the second solar cell panel G2 (or the second wind turbine M2, the second water flow generator MS2) through the second control power input terminal and the second normally open contact terminal of relay K1 (or K3 and K5) and will be unidirectionally conducted into the positive electrode of the battery pack G through the diode VD1 (or VD3 and VD5). The negative electrode of the first solar panel G1 (or the first wind generator M1, the first water flow generator MS1) will be connected to the negative electrode of the second solar panel G2 (or the second wind generator M2, the second water flow generator MS2) through the third control power input terminal and the third normally open contact terminal of the relay K1 (or K3, K5) and will be unidirectionally conducted to the negative electrode of the battery group G through the diode VD2 (or VD4, VD5) to charge the battery. Since the two solar panels G1, G2 (or the two water flow generators MS1, the two wind generators M1) are in parallel at this moment, the charging voltage of the battery G reaches a suitable voltage, which prevents the two solar panels G1, G2 (or the two water flow generators MS1, the two wind generators M1) from being too high in series and affecting the service life of the battery (too high charging voltage is not good for the use of the battery).

[0021] Figure 1; As shown in Figure 2, through the above, the present invention has multiple water flow generators installed in series in the water pipe. Compared with the existing single installation of a water flow generator, it fully utilizes the electric energy generated by the flow of tap water, which is equivalent to realizing cascade power generation, and has higher power generation efficiency than the power generation of a single water flow generator. The present invention groups every two solar panels, every two wind turbines, and every two water flow generators into a group. Under the action of the control circuit, when the voltage of the generator is lower than a certain value, the two generators are connected in series to charge the battery pack. When the voltage is higher than a certain value, the two generators are connected in parallel to charge the battery pack. This not only effectively utilizes the electric energy generated by the generators under low water flow, low wind force, and low light, but also realizes the effect of improving the power generation efficiency by water flow series power generation. Before production of the present invention, it is necessary to determine the resistance value of the adjustable resistor RP (or RP1, RP2). When determining, for example, the power generation voltage of the generator is 12V and the voltage of the battery group G is also 12V, an external adjustable voltage-stabilized power supply is connected to one end of the adjustable resistor RP (or RP1, RP2) and the emitter of the NPN transistor Q2 (or Q4, Q6), and the output of the adjustable voltage-stabilized power supply is adjusted below 12V. Then, the resistance value of the adjustable resistor RP (or RP1, RP2) is slowly adjusted until the relay K (or K2, K4) loses power, and the resistance value is adjusted to the required value (when the subsequent generator voltage is lower than 12V, the control circuit can generate electricity in parallel). After adjustment, the resistance value of the adjustable resistor RP (or RP1, RP2) is tested. No further testing is required for subsequent production, and the resistance value of the adjustable resistor RP (or RP1, RP2) can be directly adjusted to the desired value. The model of NPN transistors Q1, Q2, Q3, Q4, Q5, and Q6 is 9013; the relays K, K1, K2, K3, K4, and K5 are DC12V relays, among which the relays K1, K3, and K5 have three control power input terminals, three normally open contact terminals, and three normally closed contact terminals; the model of adjustable resistors RP, RP1, and RP2 is 8M; the model of diodes VD1, VD2, VD3, VD4, VD5, and VD6 is 1N4007.

[0022] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It is obvious to those skilled in the art that the present invention is limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention.

This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole.
