Wind-solar complementary street lamp control device

technical field

The utility model relates to a street lamp control device, more precisely a wind-solar complementary street lamp control device, in particular to a wind-solar complementary street lamp control device adopting Zigbee wireless control technology.

Background technique

Street lamps are the main part of urban lighting projects. At night, the lighting of street lamps plays a very important role. But while street lamps play an important role, they also consume a lot of energy. Although wind-solar hybrid street lamps use renewable energy to generate electricity, most of their controllers use independent monitors, and the street lamps are lit for a long time, so the electric energy is wasted in vain. In a city, in addition to the main road, there are many arterial roads and small road sections. The flow of people and traffic on these streets at night is relatively small. Especially in some suburbs and relatively remote road sections, after 1 o'clock in the middle of the night, the flow of people and vehicles is generally very small, and the real effective lighting time of many road sections only accounts for 20%-30% of the entire lighting time, that is to say Part of the power is wasted.

Zigbee is synonymous with the IEEE 802.15.4 protocol. The technology specified in this protocol is a short-range, low-power wireless communication technology, which is characterized by short-distance, low complexity, self-organization, low power consumption, and low data rate. , low cost, mainly suitable for automatic control and remote control fields, and can be embedded in various devices.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

It can be seen from Figure 1 that a wind-solar hybrid street lamp control device includes a street lamp monitor composed of an MCU micro-control unit, a diagnostic module, and a control module. The detection data of the diagnostic module is sent to the MCU micro-control unit for processing and then transmitted to the control module To control the lighting and brightness of street lamps, each street lamp monitor is connected through a wireless communication module to form a subnet monitor to realize the control of each street lamp.

The wireless communication module described in the utility model is a wireless communication module using Zigbee technology.

The diagnostic module described in the utility model includes a photosensitive sensor, a sound sensor, a current detector, a vibration sensor, a pressure sensor, and an infrared sensor.

The control module described in the utility model includes an executive switch and a voltage regulating controller.

When the utility model is applied, the detection data of each sensor in the diagnostic module is sent to the MCU micro-control unit for processing, and according to the working environment around the street lamp, the monitoring device can timely control the shutdown or opening of the street lamp and adjust the brightness of the light. At the same time, it greatly reduces power consumption, saves power consumption, and prolongs the life of the light source.

When people or vehicles pass by, an invisible infrared signal is generated. Infrared sensors can effectively detect the passing of people or vehicles.

The pressure sensor is used to detect the pressure generated on the ground when vehicles and people pass by, and the pressure sensor is distributed under the road surface at the main position of the road.

The photosensitive sensor has two functions, detecting ambient light and detecting street light intensity. Detect the ambient light intensity when the street lamp is turned off, and detect the luminous brightness of the street lamp when the street lamp is on; when the aging of the street lamp causes the luminous brightness to decrease, an adjustment signal can be generated to keep the lighting brightness unchanged. If the brightness is always insufficient, an alarm signal will be generated to prompt timely replacement and maintenance.

When a vehicle passes by, a vibration signal is generated. The vibration sensor detects this signal and can judge whether there is a vehicle passing by.

The sound sensor mainly detects the sound produced when vehicles pass by.

Current detectors are used to detect whether a street light is on or malfunctioning.

The execution switch and the voltage regulating controller in the control module of the utility model are used to control the time and brightness of the street light switch.

Because the working environment around the street lamp is very complicated, in order to prevent wrong judgment, the sensor needs to have high sensitivity, and it is also necessary to synthesize the signals of multiple sensors, and make a comprehensive judgment according to a certain algorithm, so as to obtain more accurate results and effectively control the street lamp state.

The utility model consists of a plurality of Zigbee street lamp monitors to form a subnet monitor, and the plurality of subnet monitors and a control center form a street lamp wireless monitoring network.

The subnet monitor receives and sends all street lamp control signals, data records, alarm processing, etc. in the subnet. Upward communicates with the control center through GPRS or 485, RS232, etc., and downward communicates with various street lamp monitors through ZigBee communication protocol.

The control center conducts remote data access and monitoring of each street lamp monitor under different subnets through the monitoring management system, including parameter configuration, monitoring command sending, on-site lamp status collection and management, etc.
