Abstract

Simulated solar light system to the battery charge, battery load to discharge, such as light bulbs. Charge current and temperature by the care of the two conditions, the stronger the illumination, temperature, the higher the charge current is stronger, with more obvious effects of illumination.

I. Introduction

The working principle of the battery - a charge-discharge cycle as an example, in a cycle can be any of the state without electricity. LVD title at this time point, that is, when the battery voltage under-voltage disconnect, when the battery discharge voltage is lower than LVD, the battery disconnected, there is no current output, the beginning of charge, voltage rise, when the arrival of HVD or disconnected when the battery is full voltage, the battery disconnected, there is no current output, HVD after arrival, after the battery voltage slowly drop their own, the current dropped to a certain extent, that is, to restore battery charge voltage, the battery will continue charging until the HVD disconnected, so repeated N times, battery charge after discharge after the battery discharge, the voltage will gradually decrease until the point LVD disconnect, disconnect after the voltage will gradually rise, until the arrival of the battery discharge voltage to resume after the discharge, the same repeated N times, the end of discharge . Mobile phone battery in no time after power reboot is also used for some time for this reason.

Second, system architecture

Architecture Description - HMIBuilder generic version of software is an unlimited point of configuration software (simulation and load PV panels need a large number of variables and calculations, so a lot of variables), Industrial Computer, Advantech PCI1713 analog high-speed acquisition card, Advantech PCI1620 multi-string I communication card (where a number of systems), programmable power supplies, programmable load, current sensors, temperature sensors.

Third, the engineering characteristics of

The biggest bright spot of the system is generic version of a wireless point HMIBuilder configuration software sets in engineering data acquisition, data processing, the control package.
Data Acquisition - Acquisition through PCI1713 current through the sensor, the temperature signal.
- Acquisition through the RS-232 programmable power supply, programmable load voltage and current signals.
Data - HMIBuilder their support through a powerful scripting system procedures and functions required for calculating the voltage and current relations, such as the completion of computing points. Data processing - through the historical curve, real-time curve analysis it is clear the system, the state and trends of various parameters, easy access to fault conditions, and data extraction can facilitate the adoption of the system parameters to draw the maximum, minimum, average, etc. the realization of the analysis of system parameters.
Control - totally dependent on the configuration of the system software to control the whole process, equipment start and stop. In addition the system through the expansion of the PCI1620 serial 8 to meet the requirements of multi-system.
Software Analysis:
User interface: the user interface contains the system status display, parameter setting, timing settings, real-time curve, the history of curves, data extraction and critical data, such as running reports can clearly see that the interface power supply, load, battery condition, parameters, a smooth control the implementation of the steps, and real-time curves can click button at the same time to switch to other systems, set parameters, such as query history curve for the operation and monitor the operation of the entire system.

The chart is part of print data report, which forms the main data in the system are automatically generated during the operation, only need to click the Print button you want to be able to print out the forms, under the plan is the effectiveness of print, print Print button, such as within the scope of not.

Configuration software can support a number of strategies at the same time, you can choose according to need different strategies and components, easy computing for data extraction and system control requirements.
