Embodiment Construction

[0014] figure 1 As shown, the vehicle detectors arranged at certain distances on the road detect whether there is a vehicle passing by, and the detectors may be infrared detectors, ultrasonic radar detectors or pressure sensors. When a vehicle passes by, the vehicle detector measures and generates an induction signal, which is converted and processed by the signal conversion processing module, and then the converted signal is transmitted to the single-chip microcomputer in the control unit through the signal transmission channel. The signal transmission channel can be RS-232, RS-484, RS-422 serial connection or Ethernet TCP / IP connection, and can also be wireless network transmission. The pre-set control program is stored in the single-chip microcomputer. Through the analysis and judgment of the received signal, the electronic switch of the street lamp is controlled to open and close, thereby controlling the working state of the driving power supply and controlling the o...

Abstract

The invention discloses an intelligent street lamp system based on the traffic flow of a measured vehicle. The intelligent street lamp system comprises a group of street lamps consisting of a street lamp cap, a driving power supply and a control unit as well as vehicle detectors which are arranged on the road at every certain distance, wherein the vehicle detectors are connected with a signal converting and processing module and is connected with a singlechip computer in the control unit through a signal transmission channel; and the singlechip computer is used for processing a signal detected by the vehicle detector. The intelligent street lamp system achieves the functions of illumination when the vehicle passes and extinguish when no vehicle passes in the road illumination, thus energy is saved under the condition of ensuring the safe passing of the vehicle.

Description

technical field [0001] The invention relates to a street lamp, and more specifically, to an intelligent control system for a street lamp. Background technique [0002] Ordinary street lights, no matter whether there are people passing by or not, are always on, including in remote areas where the traffic is clearly distinguished and at night when the traffic flow is greatly reduced compared with the day. When there is no car passing on the road for a long time, this constant light state will inevitably cause a serious waste of energy, and its irrationality is obviously highlighted. Therefore, the energy-saving control of road lighting has become a research direction that people pay close attention to. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides an intelligent street lamp system based on the measurement of traffic flow, which realizes the function of turning on when there is a car and turning off when ...
