Description

Device for detecting noise radiation

Technical Field

The invention relates to the technical field of noise radiation detection, in particular to a device for detecting noise radiation.

Background

With the improvement of the living standard of people, the living quality of people is continuously improved, wherein the noise radiation pollution is highly valued.

For noise pollution improvement, noise is monitored first, and for this reason, a noise radiation detector is developed, and generally, the noise radiation detector is composed of a condenser microphone, a preamplifier, an attenuator, an amplifier, a frequency weighting network, a display and the like. The working principle of the noise radiation detector is that a microphone converts sound into an electric signal, and then a preamplifier converts impedance to match the microphone with an attenuator. The amplifier adds the output signal to weighting network to do frequency weighting or external filter to the signal, then the signal is amplified to a certain amplitude by attenuator and amplifier and sent to effective value detector or external level recorder to give the value of noise level on the display, the frequency weighting network in the noise meter has A, B, C three standard weighting networks. The A network simulates the response of human ears to pure 40-square tones in an equal loudness curve, and the shape of the noise meter curve of the A network is opposite to that of the equal loudness curve of 340-square tones, so that the middle and low frequency bands of the electric signals have larger attenuation. The B network simulates the response of the human ear to a pure 70 square tone, and it attenuates the low frequency band of the electrical signal to some extent. The C-network simulates the response of the human ear to a pure 100 square tone, with a nearly flat response over the entire audio frequency range. The sound pressure level measured by the sound level meter through the frequency weighting network is called sound level, and the sound level is called A sound level, B sound level and C sound level respectively according to different weighting networks, and the units are marked as dB (A), dB (B) and dB (C).

1. because the shell of the existing device for detecting the noise radiation is only provided with fixing structures such as hooks, fixing sheets and the like simply, the mounting and fixing mode is not flexible,

The working principle of the device is as follows: 1. in one day, the sun moves relative to the earth from east to west due to the rotation of the earth, in the process, the illumination intensity irradiated on the solar cell panel is different when the sun rotates by an angle, wherein one main reason influencing the illumination intensity is that the included angle between the light emitted by the sun and the solar cell panel is changed along with the movement of the sun, the solar utilization rate is the largest when the sunlight almost vertically irradiates on the solar cell panel in a normal state, in order to improve the solar utilization rate, in the scheme, the motor is controlled to rotate through reasonable operation to drive the solar cell panel to rotate along with the sun when the condition is met, so that the change of the included angle between the light emitted by the sun and the solar cell panel is reduced, and the solar utilization rate is improved, wherein when the absolute value | Δ a1| of the difference reaches the minimum threshold value, the change of the illumination value E1 corresponding to the starting time t1 and the illumination value E2 corresponding to the ending time t2 is explained to obviously influence the solar cell panel The utilization rate of the solar panel to the sun should be adjusted. At this moment, the processor controls the motor to be powered on and rotate clockwise for a certain angle, then the power of the motor is cut off, so as to reduce the change of an included angle between the light rays emitted by the sun and the solar panel and improve the utilization rate of solar energy, of course, the shorter the first time period is, the higher the utilization rate of the solar energy is, however, the motor needs to consume energy in rotation, therefore, the value of the first time period is reasonable, in the application, the first time period can be set to be between one quarter of a quarter and three quarter of a quarter, when the absolute value | Δ a1| of the difference reaches the maximum threshold value, the sunlight is insufficient, the weather is cloudy or cloudy, at this moment, the energy consumed if the motor rotates is much higher than the electric energy generated by adjusting the solar panel, therefore, the processor cuts off the power of the motor at this moment so as to save the electric energy, of course, if the motor is in the power, when the sun falls into a mountain, the motor is required to recover the initial position and repeatedly operate in the tomorrow; it should be noted that, in this application, a manual control switch may be further provided to control the rotation of the motor, so as to reasonably adjust the orientation of the solar cell panel.

2. In one year, due to the revolution of the earth, the sun moves from east to west relative to the earth and also moves in the north-south direction, thereby leading to different irradiation angles of the sun to the solar panel and influencing the solar energy utilization rate, when the difference value delta E2 is less than zero, the solar cationic earth moves from far to near, the included angle (more than or equal to zero and less than or equal to ninety degrees) between the light irradiated on the earth by sunlight and the ground is increased, when the absolute value of the difference value delta E reaches a minimum threshold value, the change of the angle of the solar energy irradiating the solar cell panel is indicated to obviously influence the utilization rate of the solar energy by the solar cell panel, at the moment, the processor controls the electric telescopic device to shorten, so that the included angle between the solar cell panel and the ground is reduced, so that sunlight can vertically irradiate the solar cell panel as much as possible, and the utilization rate of the solar cell panel to solar energy is improved;

when the difference value deltaE 2 is greater than zero, which indicates that the tera-cation earth moves from near to far, the included angle between the light irradiated on the earth by sunlight and the ground (greater than or equal to zero and less than or equal to ninety degrees) is reduced, when the absolute value of the difference value delta E reaches a minimum threshold value, the change of the angle of the solar panel irradiated by the sun is explained to obviously influence the utilization rate of the solar panel to the solar energy, at the moment, the processor controls the electric telescopic device to extend, so that the included angle between the solar panel and the ground is enlarged, so that the sunlight can be vertically irradiated on the solar cell panel as much as possible, the utilization rate of the solar cell panel to the solar energy is improved, and it should be noted that, in the application, a manual control switch can be arranged to control the expansion of the electric expansion device, so as to reasonably adjust the inclination angle of the solar panel relative to the ground, wherein the ground can be understood as a horizontal plane.
