Abstract
The utility model provides a rain sensor based on an acceleration sensor, which belongs to the sensor field and comprises a vibrating diaphragm, the acceleration sensor arranged on the inner wall of the vibrating diaphragm and a vibrating diaphragm bracket connected with the inner wall of the vibrating diaphragm; the acceleration sensor is positioned in the vibrating membrane bracket; the outer wall of the vibration film is in contact with the raindrops. Compared with the prior art, the utility model has simple structure, and the circuit is not corroded by rainwater because the rainwater is not directly contacted with the circuits such as the acceleration sensor and the like and the corrosion-resistant vibration film is arranged in the middle of the acceleration sensor; and by reading the acceleration sensor, the frequency and the strength of raindrops falling can be known in real time without a windscreen wiper. Thereby being convenient to use, safe and reliable.
Description
Technical Field
The utility model relates to a sensor technical field specifically indicates a rain sensor for responding to rainfall.
Background
In order to guide agricultural production and detect whether the rain falls and the rainfall amount, a rain sensor is needed; the existing rain sensor adopts a resistance contact mode, has a simple principle and is easily corroded by rain; or adopt the photoelectricity way, for example the car, but need wiper blade to renew the rainy state in time, there is the inconvenience in using.
SUMMERY OF THE UTILITY MODEL
In order to overcome the shortcomings of the prior art, the utility model aims to provide a simple structure, safe and reliable's rainwater sensor based on acceleration sensor.
In order to achieve the above object, the utility model adopts the following technical scheme: a rainwater sensor based on an acceleration sensor comprises a vibrating membrane, the acceleration sensor arranged on the inner wall of the vibrating membrane, and a vibrating membrane bracket connected with the inner surface edge of the vibrating membrane; the acceleration sensor is positioned in the vibrating membrane bracket; the outer wall of the vibration film is in contact with the raindrops. The vibrating membrane is made of an anti-corrosion and easily-vibrated material, the acceleration sensor is tightly attached to the inner wall of the vibrating membrane, rain drops are knocked on the vibrating membrane when the vibrating membrane is in rainfall to cause vibration of the vibrating membrane, the vibration can be transmitted to the acceleration sensor tightly attached to the lower portion of the vibrating membrane, and the acceleration sensor can transmit the vibration to processing or executing mechanisms such as an MCU (microprogrammed control unit) in an analog or digital mode through the interface circuit. By reading the data of the acceleration sensor, the frequency, the intensity and the like of the raindrops falling can be known, so that whether the raindrops fall or not at present and the intensity of the raindrops can be known.
Preferably, the vibration membrane is circular, and the vibration membrane bracket is annular; the diameter of the outer circle of the vibration film support is the same as that of the vibration film.
The beneficial technical effects are as follows: compared with the prior art, the utility model has simple structure, and the circuit is not corroded by rainwater because the rainwater is not directly contacted with the circuits such as the acceleration sensor and the like and the corrosion-resistant vibration film is arranged in the middle of the acceleration sensor; and by reading the acceleration sensor, the frequency and the strength of raindrops falling can be known in real time without a windscreen wiper. Thereby being convenient to use, safe and reliable.

fig. 2 is a top view of the present invention.
Detailed Description
In order to make the technical field better understand the present invention, the following detailed description of the present invention is provided with reference to the accompanying drawings and embodiments.
As shown in fig. 1-2, an acceleration sensor-based rain sensor comprises a vibrating membrane 1, an acceleration sensor 2 arranged on the inner wall of the vibrating membrane, and a vibrating membrane support 3 connected with the inner surface edge of the vibrating membrane; the acceleration sensor 2 is positioned in the vibrating membrane bracket 3; the outer wall of the vibrating membrane is in contact with the raindrops 4.
Here, the vibration diaphragm 1 is circular, and the vibration diaphragm support 3 is circular; the diameter of the excircle of the vibration film support 3 is the same as that of the vibration film 1.
The vibrating membrane 1 is made of an anti-corrosion and easily-vibrated material, namely the vibrating membrane is easy to sense vibration, the acceleration sensor 2 is tightly attached to the inner wall of the vibrating membrane, raindrops 4 are knocked on the vibrating membrane 1 during rainfall to cause vibration of the vibrating membrane 1, the vibration can be transmitted to the acceleration sensor 2 tightly attached to the lower portion of the vibrating membrane, and the acceleration sensor 2 can transmit the vibration to processing or executing mechanisms such as an MCU (microprogrammed control unit) in an analog or digital mode through an interface circuit. By reading the data of the acceleration sensor 2, the frequency, intensity, etc. of the raindrops falling can be known, and thus whether it is raining at present and the intensity of the raining can be known.
Compared with the prior art, the utility model has simple structure, and the circuit can not be corroded by the rainwater because the rainwater is not directly contacted with the circuits such as the acceleration sensor 2 and the like and the middle is provided with the corrosion-resistant and easily-vibrated vibrating membrane 1; and by reading the acceleration sensor 2, the frequency and the strength of raindrops falling can be known in real time without a windscreen wiper. Thereby being convenient to use, safe and reliable.
In the above description, it should be noted that the terms "mounted," "connected," and "connected" are used in a broad sense, and may be, for example, fixedly connected, detachably connected, or integrally connected; the connection may be direct or indirect via an intermediate medium, and the connection may be internal to the two components.
Although the present invention has been described in terms of embodiments, those skilled in the art will recognize that there are numerous variations and modifications of the present invention without departing from the spirit of the invention, and it is intended that the appended claims encompass such variations and modifications without departing from the spirit of the invention.
