Abstract

A kind of device of on-line checkingi solar module voltage, the positive pole of solar panel is by being connected to the positive terminal of the light-emitting diode of photoelectrical coupler after adjustable resistance and the first fixed resistance, the negative pole of solar module is connected to the negative pole end of photoelectrical coupler light-emitting diode, the collector terminal of photoelectrical coupler is connected to DC power supply, the emitter terminal of photoelectrical coupler is by the second fixed resistance ground connection, the emitter terminal of photoelectrical coupler is also connected to the positive input terminal of emitter follower simultaneously, the output of emitter follower is connected to the A/D interface of computer.The voltage data of solar photovoltaic generation system battery component can be obtained thus, reach the object of the performance of battery component being carried out to Real-Time Monitoring.Once certain block assembly breaks down, energy output is lower than set point, and checkout gear just can find and report to the police, so that user is in time to the assembly maintenance damaged and replacing, is in kilter to keep solar photovoltaic generation system.

Description

A kind of device of on-line checkingi solar module voltage
Technical field
The utility model relates to the device, particularly a kind of device of on-line checkingi solar module voltage that a kind of solar photovoltaic generation system uses.
Background technology
Conventional solar photovoltaic generation system, does not all arrange the device of on-line checkingi battery component voltage.Because solar photovoltaic generation system is multiple battery component running of pumps in series parallel connections, once there be certain assembly to damage the output that will affect whole component string, cause the decline of energy output.The device of on-line checkingi solar module voltage is set, can on-line checkingi whether normal to the generating of battery component, once certain block assembly breaks down, energy output is lower than set point, just can report to the police, so that maintenance in time and replacing, be in kilter to keep solar photovoltaic generation system.Because the quantity of the solar module of solar photovoltaic generation system is very large, on-line measuring device with low costly just must have promotional value, data terminal and input also must reliably be isolated simultaneously, make checkout gear can not affect the generating of solar energy photovoltaic system.
Through retrieval, in the invention of existing solar photovoltaic generation system, the invention of also not identical with the utility model solar-energy photo-voltaic cell on-line measuring device.
Summary of the invention
The purpose of this utility model is to provide a kind of device of on-line checkingi solar photovoltaic battery component voltage, can carry out Real-Time Monitoring to the voltage of solar panel.
The purpose of this utility model realizes by the following method:
A device for on-line checkingi solar module voltage, is characterized in that:
The positive pole of solar panel is by being connected to the positive terminal of the light-emitting diode of photoelectrical coupler after adjustable resistance and the first fixed resistance, the negative pole of solar module is connected to the negative pole end of photoelectrical coupler light-emitting diode, the collector terminal of photoelectrical coupler is connected to DC power supply, the emitter terminal of photoelectrical coupler is by the second fixed resistance ground connection, the emitter terminal of photoelectrical coupler is also connected to the positive input terminal of emitter follower simultaneously, and the output of emitter follower is connected to the A/D interface of computer.
The device of the utility model on-line checkingi solar photovoltaic battery component voltage can obtain the voltage data of solar photovoltaic generation system battery component, can reach the object of monitoring in real time the performance of battery component.Once certain block assembly breaks down, energy output is lower than set point, and checkout gear just can find and report to the police, so that user is in time to the assembly maintenance damaged and replacing, is in kilter to keep solar photovoltaic generation system.
Accompanying drawing explanation
Fig. 1 is embodiment schematic diagram of the present utility model.
Embodiment
1 embodiment is for a more detailed description to the utility model by reference to the accompanying drawings:
A device for on-line checkingi solar-energy photo-voltaic cell voltage, by solar module 1, adjustable resistance 2, the first fixed resistance 3, photoelectrical coupler 4, the second fixed resistance 5, emitter follower 6, computer 7 is formed.The positive pole of solar panel 1 is by being connected to the positive terminal of the light-emitting diode of photoelectrical coupler 4 after adjustable resistance 2 and the first fixed resistance 3, the negative pole of solar module 1 is connected to the negative pole end of the light-emitting diode of photoelectrical coupler 4, the collector terminal of photoelectrical coupler 4 is connected to DC power supply, the emitter terminal of photoelectrical coupler 4 is by the second fixed resistance 5 ground connection, the emitter terminal of photoelectrical coupler 4 is also connected to the positive input terminal of emitter follower 6 simultaneously, and the output of emitter follower 6 is connected to the A/D interface of computer 7.
During system cloud gray model, the voltage of solar module 1 is isolated by photoelectrical coupler 4 and is amplified, then is connected to the A/D interface of single-chip microcomputer 7 through the output of emitter follower 6, is collected by computer 7 and processes the voltage data collected.The voltage data of the battery component of solar photovoltaic generation system can be obtained thus, reach the object that the performance of battery component is monitored.
