Using the weather parameter for pre-setting, control signal is sent out to steering wheel by single-chip microcomputer, cell panel is turned into the sun, carried out Photovoltaic is day by day, it is ensured that be collected into most solar energy on sunny daytime.Simultaneously internally by Single-chip Controlling perturbation observation method Implement the tracking of maximum power point, it is ensured that in maximum power point output.The connection with electrical appliance is automatically cut off at night, it is ensured that use Security, the reliability of electrical equipment and photovoltaic battery panel.While daily power supply, team's photovoltaic generating system of the present invention, built-in day Parameter is waited, peace looks for weather to set, and photovoltaic battery panel auto-steering realizes photovoltaic day by day.Simultaneously inside battery using MPPT with Track maximum power point, remains the maximum output of battery, while the data collected using the sensor of Internet of Things, it is ensured that cloudy Rain and night photovoltaic cell cut off itself and extraneous connection, it is ensured that the efficient stable of range system.
Brief description of the drawings
Fig. 1 is the functional schematic of family's Internet of things system of photovoltaic energy supply of the present invention.
Specific embodiment
Family Internet of things system of the present invention based on photovoltaic energy supply includes：Photovoltaic generation unit, energy storage unit, family Internet of Things net unit；Described light photovoltaic generation unit, energy storage unit, family's Internet of Things net unit are sequentially connected, family's Internet of Things Net unit is connected with photovoltaic generation unit.Described photovoltaic generation unit, by photovoltaic solar cell plate, DC-DC circuit, rudder Machine, single-chip microcomputer, electric energy output, gate-controlled switch composition solar energy, cell panel is exported with electric energy by gate-controlled switch and is connected, and is passed through DC-DC circuit fish single-chip microcomputer steering wheel is connected, and single-chip microcomputer is directly connected to steering wheel gate-controlled switch.Described Internet of Things net unit, by thing Networking gateway, sensor group, controllable gating switch composition.Things-internet gateway and sensor group, by gating switch and power network, Energy storage device, photovoltaic battery panel are connected.
Preferably, described energy-storage units are large-capacity battery.
It is as shown in Figure 1 the functional schematic of family's Internet of things system of photovoltaic energy supply of the present invention,
Embodiment one, in bright day gas, when daytime, photovoltaic generating system of the invention, normal power generation energy supply, Simultaneously can be according to the parameter day by day calculated according to weather parameter set in advance, according to the right of time adjustment photovoltaic battery panel Day angle, farthest collects solar energy.The tracking of maximum power point is carried out according to the MPPT for setting simultaneously, is remained Photovoltaic solar cell plate exports electric energy in most power points, improves the bringing onto load performance of cell panel.
The electric energy of solar panel directly feeds the gateway of the internet of things sensors of family expenses and the power consumption of sensor. Things-internet gateway and sensor need electric energy it is less, while being directly accomplished by direct current, then the electric energy of photovoltaic battery panel can By DC-DC voltage transformations being directly Internet of Things mesh portions energy supply above.The data guessed of sensor of Internet of Things simultaneously, can be with Photovoltaic solar cell plate is fed back to after the data such as current intensity of illumination, time, weather are calculated, repairing for parameter is carried out day by day Just.The connection of cell panel and system can be cut off when weather photoenvironment is poor simultaneously.
Energy-storage system, mainly using battery, while photovoltaic cell is to Internet of Things sensing, control system energy supply, be Energy-storage system is charged, and remaining energy regenerating is collected.When to night or not enough rainy weather illumination, energy-storage system Sensing, the control system energy supply of Internet of Things can be preferably, consumption of this part for power network electric energy is farthest reduced.
When the illumination deficiency that this part of embodiment two is caused primarily directed to severe point weather or night.At this moment Waiting solar panel can not only send electric energy, if cut off with power network not in time, solar panel will become to use Electrical equipment, at this time will be not only adjusted, in addition it is also necessary to by the sensor of Internet of Things by itself parameter set in cell panel The optical parameter for just obtaining is judged that acquisition data are corrected to current existing parameter, even directly cut off photovoltaic electric Pond plate and the connection of the system, prevent cell panel consumed energy.
Meanwhile, the photovoltaic generation that the energy ezpenditure of Internet of things system is preferentially collected using energy-storage system obtains electric energy, due to What current gateway also had that sensor is all is the product of low-power consumption, so this part electric energy can amount to thing in long-time The sensing and control gateway of networking are used.While using this part electric energy, regularly estimate saving a bit, in energy storage Before device electric energy exhausts, the power consumption of Internet of Things is switched to consumption power grid energy, prevents Internet of things system from powering off.
In sum, the system can provide different embodiments for different environment, realize Internet of things system With the combination of photovoltaic generating system, new energy is farthest make use of, reduce Internet of things system for network system Energy ezpenditure, systematic analysis is reliable and stable, convenient to carry out, with economic benefit and promotional value very high.
