Description

Technical Field

[0001] The invention belongs to the field of environmental protection detection, and in particular relates to a fixed-point area light pollution detection device installed outside a building. Background Art

[0002] Light pollution is a new source of environmental pollution after waste gas, waste water, waste residue and noise pollution. It mainly includes white light pollution, artificial daylight pollution and color light pollution. The impact of light pollution on people's health and life is becoming increasingly serious. In daily life, people's common light pollution conditions are mostly caused by the reflection of mirror buildings, which causes dizziness to pedestrians and drivers, and the discomfort caused by unreasonable lighting at night. With the continuous improvement of people's requirements for quality of life and the emphasis on mental health, this problem has been raised to a greater extent. In this context, the detection of light pollution and the formulation of control plans have become the focus of the work and research of environmental protection departments. It has become a top priority to find ways to improve and enhance the quality of life of residents.

[0003] Since the structure of houses on urban streets is relatively complex, it is necessary to detect in a specific area or direction. How to install and position the detection device becomes the key to the problem of light pollution environment detection. Under this premise, the present invention proposes a light pollution detection device installed outside the building to solve the problems in the above background technology. Summary of the invention

BRIEF DESCRIPTION OF THE DRAWINGS

[0008] Figure 1 It is a schematic diagram of the principle and structure of the device of the present invention. DETAILED DESCRIPTION

[0009] The structure of the present invention is further described in detail below with reference to the accompanying drawings and through embodiments.

[0010] like Figure 1 As shown, the device installed on the outside of the building for light pollution inspection of the fixed area has the following structure: the structure of the door-type fixed frame 1 is two door pillars, one long and one short, the long arm end is fixed to the outer wall of the building; the short wall end is hoisted and fixed with a protective shell 2. A two-layer partition board is provided at the top of the protective shell, and a single-chip computer 4 is installed on the first layer of partition board 3-1; a light pollution detector 7 is installed on the second layer of partition board 3-2, and the light pollution detector is connected to a data storage unit 12 and a connection transmission unit 13, and the light pollution detector is connected to the single-chip computer through a data line. The servo motor 5 is fixed at the center position below the second layer of partition board. A hollow fixed chuck 6 is installed at the bottom end of the protective shell, and the outer diameter of the hollow fixed chuck is larger than the outer diameter of the protective shell. A stopper is provided around the periphery of the light receiving detector 8, and it is mounted on the hollow fixed chuck in the protective shell through the stopper. A bearing ring 9 is installed between the stop of the light receiving detector and the contact surface of the hollow fixed chuck. The servo motor shaft 5-1 is fixedly connected to the top of the light receiving detector. The servo motor drives the light receiving detector to rotate on the hollow fixed chuck. 2 to 4 ambient light intensity detection probes 8-1 are fixedly installed under the hollow fixed chuck located outside the protective shell. The light receiving detector is provided with a light-transmitting cover 10, and the outside of the light-transmitting cover is covered with a selective light high-transmittance film. A cooling fan 11 is installed on the outer wall of the protective shell, and the cooling fan is fixed to the upper surface of the hollow fixed chuck outside the protective shell.

[0011] The servo motor, light pollution detector, light receiving detector, ambient light intensity detection probe, and cooling fan are connected to the single-chip microcomputer. The ambient light intensity detection probe works 24 hours a day. When the detected external light environment brightness exceeds the "specified value", the ambient light intensity detection probe triggers the single-chip microcomputer to work, and the servo motor rotates the direction of the light receiving detector to receive and control the ambient light pollution light source signal.

[0012] The outer wall of the protective shell is arc-shaped, and a water guide groove is arranged around the hollow fixed chuck, and rainwater in the protective shell can be drained through the water guide groove. The outer wall of the protective shell is provided with an outer cover 14 for installing a cooling fan, and the outer cover is processed with cooling holes.

[0013] As an embodiment, the detection device is fixed to the outer wall by bolts through the fixing bolt installation through hole 1-1 provided at the long arm end of the door-shaped fixing frame. The exterior of the light receiving detector is circular, and the inner diameter of the hollow fixing chuck is smaller than the outer diameter of the light receiving detector. A stop is provided around the periphery of the light receiving detector, so that the light receiving detector can be placed on the hollow fixing chuck. Because a bearing ring is provided between the periphery of the light receiving detector and the contact surface of the hollow fixing chuck, the steering resistance is very small when the servo motor drives the light receiving detector to rotate. The protective shell part of the detection device is fixed on the building outside the wall, and the light receiving detector is constantly rotating.

[0014] The light receiving detector is provided with a light-transmitting cover, which is a transparent film with high transmittance of visible light. At the same time, the film can block the entry of infrared, ultraviolet and other stray light, which is the characteristic of selective light materials. At the same time, the light-transmitting cover also protects the light receiving detector. The ambient light intensity detection probe receiver probe is fixed at the lower end of the hollow fixed chuck (outside the protective shell) and can work 24 hours a day. According to the signal received by the ambient light intensity detection probe, the light receiving detector can rotate clockwise or counterclockwise under the drive of the servo motor to continuously scan the ambient light pollution of the locked area. The time period of continuous operation of the light receiving detector is based on the information provided by the ambient light intensity detection probe. The light receiving detector transmits the light environment information to the storage unit of the light pollution detection machine for short-term storage in real time, and transmits it to the single-chip microcomputer through the transmission unit. The light pollution detection process is calculated and controlled by the single-chip microcomputer. When the equipment in the protective shell runs for a long time and the ambient temperature reaches the predetermined upper limit, the cooling fan on the outer wall of the protective shell will automatically turn on.

[0015] The second layer of partition board in the protective shell is thicker than the first layer, and it has a load-bearing function. The servo motor and the light receiving detector connected thereto are installed on it. This embodiment is equipped with three ambient light intensity detection probes, each probe is 120° apart, and the probe is fixed outside the protective shell. Its function is to provide a signal of the light (brightness) in the detection area, which can drive the light receiving detector to continuously change its angle.

[0016] By controlling the operation of the light pollution detector by controlling the single chip microcomputer, the light receiving detector receives the signal of the polluted light source, and the single chip microcomputer automatically controls the servo motor to rotate at different angles to adjust the scanning direction of the light receiving detector. The light receiving detector continuously detects the external light intensity. When the external light intensity is too low (the signal is obtained by the ambient light intensity detection probe) and affects the monitoring effect of the light receiving detector, the single chip microcomputer automatically adjusts the angle of the light receiving detector.

[0017] Illuminance measurement: When the ambient light brightness is relatively high at night, the signals from the light receiving detector and the ambient light intensity detection probe trigger the microcontroller to work. The microcontroller triggers the servo motor to rotate the light receiving detector to the direction of the light source. By controlling the light source signal captured by the receiver probe, continuous measurement for more than 5 minutes is achieved in accordance with the measurement method required by the "LED Display Interference Light Field Measurement Method" (GB / T 34973). The measurement results are stored for a short time through the data storage unit of the light pollution detector and transmitted to the microcontroller through the transmission unit. In addition, when the temperature of the equipment is too high, the fan automatically turns on to cool it down.

[0018] The measurement of brightness is similar to that of illumination, except that no less than 50 brightness data points must be collected in accordance with the requirements of the Field Measurement Method for Interference Light of LED Display Screens (GB / T34973).

[0019] The above description describes the structure and setting principle of the present invention. Although other improvements can be realized by those skilled in the art, they still fall within the protection scope of the invention.
