technical field

Background technique

With the development of the city, there are more and more road infrastructure street lights, which provide great convenience for people's night lighting, but at the same time of convenience, they consume a lot of electricity. With the aggravation of environmental pollution and energy crisis, energy saving and consumption reduction are becoming more and more important. Traditional street lights are usually always on all night, which causes energy waste.

The present invention combines nighttime traffic flow statistics and street lamp control of the road into one, and designs a comprehensive system based on Lora-based road street lamps and traffic flow detection.

The working principle of the power module: In the part that needs voltage conversion, the voltage input port inputs 220V voltage, and the voltage is changed through the SX2106 voltage conversion chip. After the voltage is the standard output voltage of 5V. In addition, the 220V voltage output from the voltage output port is connected to the street lamp control module, directly forms a loop with the street lamp control circuit, and controls the closing of the loop through the MOSFET driving circuit.

Control multiple groups of street lights at the same time The drive circuit realizes delay control and achieves the purpose of saving energy and reducing consumption.

The working principle of the pressure-sensitive belt circuit: the pressure-sensitive belt installed on the road is a monitoring device slightly protruding from the road surface. It crosses the road. When an object passes through the pressure-sensitive belt, the piezoresistive pressure sensor MPXV5050GP converts the mechanical pressure signal into an electrical signal. Signal, and then the electrical signal is transmitted to the I/O port of the single-chip microcomputer, and this signal is used as a start trigger signal of the single-chip microcomputer.

The street lamp control module is mainly composed of many parallel street lamps. In each individual street lamp circuit, a MOSFET drive circuit is designed. Only after the drive circuit is turned on, the circuit is closed and the street lamp is on.

The overall working principle of the present invention: the power supply module converts the input voltage of 220V into an output voltage of 5V, and the output voltage supplies energy to the single-chip microcomputer module, and the single-chip microcomputer performs signal transmission with the Lora wireless communication module through pins. At the same time, the street lamp control module is directly connected to the 220V input voltage, and supplies power through the live wire and the neutral wire, and controls the on-off of the street lamp circuit by controlling the MOSFET drive circuit, thereby controlling the on and off of the street lamp. The single-chip microcomputer circuit is connected with the pressure-sensitive belt circuit. When the pressure sensor in the pressure-sensitive circuit detects the pressure signal, the pressure-sensitive circuit sends a pulse signal to the single-chip microcomputer, and then the single-chip microcomputer sends a driving signal to the street lamp control circuit to drive the MOSFET drive circuit to control Street lights on and off. In order to control street lamps in a wider range, a Lora wireless communication module can transmit the driving signal to other multiple single-chip modules (including the single-chip microcomputer that first received the pulse signal) after receiving the driving signal of one of the single-chip microcomputer modules. Multiple single-chip microcomputer modules control multiple street lamp control modules. Through the method of delay control, the street lamps can be powered on in sequence to achieve the effect of delay control of street lamps.

(1) When the traffic flow needs to be detected, the pressure sensor detects the pressure signal, and after the signal is amplified, the output signal is transmitted to the single-chip microcomputer, and the pulse signal is output after the analog-to-digital conversion is performed inside the single-chip microcomputer. Every time a pressure signal is detected, a high-level pulse will be generated and the signal will be transmitted to the Lora wireless communication module. The Lora wireless communication module will transmit its data to the single-chip microcomputer module to determine the traffic flow and realize data sharing. At the same time, the single-chip microcomputer The delay signal is generated internally, and the pulse signal is sent out through the timer to control the on and off of the street lamp.

(2) When it is necessary to control the state of the street lamp, the pressure sensor detects the pressure signal, and after the signal is amplified, the output signal is transmitted to the single-chip microcomputer. After the analog-to-digital conversion is performed inside the single-chip microcomputer, a delay signal is generated inside the single-chip microcomputer, and a pulse is sent through the timer. The signal transmits the output signal to the MOSFET drive circuit to control the conduction state of the MOSFET, thereby controlling the on and off of the street lamp, and the trigger signal sent by the pressure sensor in each sensing area corresponds to controlling the on and off of the street lamp at the rear. After the street light is on for a period of time, it is turned off by the delayer.

(3) When it is necessary to quickly turn on and off the street lights, the LED street lights can be quickly turned on and off through the MOSFET transistor. At the same time, because the LED lights themselves are about 40% more energy-saving than the traditional halogen lights, the street lights can be realized by cooperating with the traffic flow detection on the idle road. It can save energy by at least 50% on this road section, and about 80% overall.
