Integrated control method of photovoltaic streetlamp

Abstract

The invention relates to an integrated control method of a photovoltaic streetlamp. The photovoltaic streetlamp is divided into groups, each group is provided with a main control photovoltaic streetlamp and the other groups are controlled photovoltaic streetlamps; the main control photovoltaic streetlamp is provided with more than one wireless signal transmission devices, the control part of the transmission device is formed by a photovoltaic battery, an integral control device and a clock control device which are sequentially connected together, the other controlled photovoltaic streetlamps are respectively provided with more than one wireless signal receiving devices corresponding to the wireless signal transmission devices, the photovoltaic batter, an energy storage battery and the integral control device supply power to the receiving devices, and the output ends of the receiving devices are connected with the controlled streetlamps. The integral control device and the clock control device on the main control photovoltaic streetlamp control the transmission device to transmit or stop transmitting signals, so that the output ends of the corresponding receiving devices on the controlled photovoltaic streetlamps are closed or disconnected and the controlled streetlamps are turned on or turned off so as to achieve the purposes of setting any streetlamps which are adjustable and are turned on or turned off in a unified way during the working time of the photovoltaic streetlamp.

Description

technical field [0001] The invention belongs to the technical field of photovoltaics and automatic control, and relates to an integrated control method for photovoltaic street lamps. Background technique [0002] At present, the control methods of photovoltaic street lamps mainly adopt time control (period control) and integrated (charge and discharge, light control and delay control functions in one) control; each street lamp is controlled by a control device, and photovoltaic street lamps generally have photovoltaic cells, It consists of charge and discharge controller, battery, load controller, light source, light pole and foundation. [0003] The clock control device can turn on and off the street lights at regular intervals. Each street light must have one. Due to the natural time difference, the street lights need to reset the turn-on time at the beginning and middle of each month, otherwise the street lights will turn on before it is dark. When the lights are on or t...

However, since the photoelectric characteristics of photovoltaic cells cannot be exactly the same at all, this causes each street lamp to judge the surrounding lighting conditions inconsistently, and the lighting of street lamps is inconsistent. The influence of the surrounding environment of street lamps, some are in the shadows, some are not, those in the shadows will light up earlier, and those not in the shadows will light up a little later, which also causes the effect that they cannot be lit at the same time, from the first The time difference between the lit street lamp and the last lit street lamp can reach about 10 minutes, which is worse than the simple time control effect in this respect. As a street lamp above the branch road level, it is generally not allowed. The working hours of street lamps The setting is not flexible enough, there are only a few delay programs, and it is impossible to achieve simultaneous opening or closing. Due to the charging and discharging function, each street lamp must also have a

[0005] The above two control methods mainly have the problem that photovoltaic street lamps cannot achieve a uniform effect when they are turned on and off, causing inconvenience to vehicles and pedestrians, and affecting the landscape effect of street lamps. Below the road level, it cannot be applied to secondary roads, and it cannot meet the control requirements in some special occasions such as squares
