As shown, the automatic telemetry rain gauge of this embodiment includes a sensor stage 210, a water receiver 220, a funnel 230, a bucket 240, and a water pipe 250 having a plurality of sensors 211 to 215. ), The tank 260, and the central control stage 270 can be largely divided. In addition, the sensor stage 210 includes a precipitation sensor 211, temperature sensor 212, humidity sensor 213, pH sensor 214 and turbidity sensor 215.

In addition, (solid) black arrows indicate the direction of precipitation, and (white) arrows indicate the state of movement of the atmosphere.

The automatic telemetry rain gauge of this embodiment mainly focuses on the measurement of precipitation, and measures the temperature, humidity, pH (hydrogen ion concentration) and turbidity that affect precipitation or weather changes, and comprehensively measures the relevance of each data. The central control stage 270 is provided to grasp. Precipitation is a concept that includes rainfall or snowfall, and because it has more rainfall than one of the year's geographical conditions in Korea, we use the name 'excellent meter'. This automatic telemetry rain gauge measures not only rainfall but also snowfall and other meteorological factors. Measurement is also possible. Therefore, the present invention is to measure the amount of precipitation when there is precipitation, such as rainfall or snowfall, to determine the moisture content and pollution state of the atmosphere by measuring the pH, turbidity and the like. And during normal precipitation, the atmospheric conditions such as temperature and humidity that affect the weather are measured.

First, in the rain gauge of the present embodiment, a plurality of sensors 211 to 215 provided in the sensor stage 210 measures the weather observation element, and the weather data measured by each sensor is transmitted to the central control stage 270. do.

Rain or snow during rainfall or snow falls into the rice picker 220. The water picker 220 is formed in a cylindrical shape whose top is open to receive rain or snow, and generally, the diameter Φ is about 200 mm and can be formed in a desired size as needed. A funnel network (not shown) in the form of a net is formed at the lower end of the water receiver 220 to filter out the impurities that affect the measurement of precipitation. Do it.

The funnel 230 is coupled to the bottom of the receiver 220. The funnel 230 is formed in a concave or flat shape, which gradually grows downward, and functions to flow the liquid of rain or melted snow supported by the rice picker 220 downward. Therefore, the precipitation flows out into the hole 230h which is formed under the funnel 230.

Bucket 240 is located at the bottom of the funnel 230. The bucket 240 is supported by the support (200a), the support (200a) is supported in the lower end of the rain gauge of the present embodiment is installed in the upper direction to provide a foundation on which the necessary components of the rain gauge are mounted.

The bucket 240 is a tipping type having a triangular prism shape like a thick plate as shown in the figure, and a dividing wall is formed on the central axis. Therefore, it is possible to hold a certain amount of precipitation on both sides of the central dividing wall, and when a certain amount of precipitation is filled, it is inclined to the other side like a seesaw and sends down precipitation. Precipitation is detected by the precipitation sensor 211 to counter the movement of the seesaw, and as described above, the counter value is transmitted to the central control unit 270 to determine the precipitation. In addition, in the present embodiment, the capacity of the bucket 240 is adjusted to a good depth of 0.5 mm, and this depth can be formed as needed.

Water pipes 250 are located at the lower ends of both ends of the bucket 240. This water pipe 250 may be referred to as a pipe that drains the precipitation flowing from both ends of the bucket 240 to the lower part of the rain gauge.

Precipitation drained from the water pipe 250 is accumulated in the water tank 260 located at the bottom of the rain gauge. The water tank 260 is in the shape of a certain volume and temporarily stores the precipitation drained through the water pipe 250. The water tank 260 of this embodiment is designed as a double cylinder, it is also possible to further install an auxiliary water tank if necessary. Therefore, after the incoming precipitation is filled in the inner barrel, it is passed over to the outer barrel by the overflow device, so that even if there is a lot of precipitation, it can be measured without any problem.

In this rain gauge, the storage time of the precipitation stored in the water tank 260 can be adjusted. That is, the water tank 260 of the rain gauge is installed with a pH sensor 214 and a turbidity sensor 215 to measure the pH (acidity, hydrogen ion concentration) and turbidity (pollution degree) of the stored precipitation and transfer it to the central control stage 270. Done. Therefore, after measuring the pH and turbidity is discharged through the lower drain (260h).

In addition, in the rain gauge of the present embodiment, a vent 200a is formed on a sidewall of the rain gauge to measure moisture and temperature of the air entering and exiting through the vent 200a. That is, the sensor stage includes a temperature sensor 212 and the humidity sensor 213, the temperature sensor 212 and the humidity sensor 213 measures the change in the temperature and humidity of the atmospheric phase and thus measured temperature and humidity Is transmitted to the central control stage 270 to be used for weather measurement and data processing. The vent 200a is sized and positioned so that rain and snow can not penetrate into the atmosphere while freely entering the atmosphere. To form.

Therefore, the sensor constituting the sensor stage 210 is provided with a processing unit for transmitting data in addition to its own sensing unit, the sensing unit itself is connected to the central control stage 270 is configured to measure various weather data do.

Therefore, when the introduced precipitation becomes full on one side of the bucket 240, when it is inclined, it flows down and is drained to the water pipe 250 on the same side, and at the same time, the precipitation is freshly opposite to the bucket 240. In this process, the precipitation sensor 211 counts the bucket 240 that acts like a seesaw and transmits the rainfall 240 to the central control unit 270 to measure precipitation due to rainfall or snowfall.

The central control stage 270 of the rain gauge receives the rainfall data measured from the sensor stage 210 and each meteorological observation data, and comprehensively processes them, and controls each component of the device as a whole and remotely controls and processes them through communication with the outside. It performs the function of transmitting the weather data.

The interface unit 271 performs an intermediate role of communicating signals with each component including the sensor terminal 210 and an external control device. Therefore, the respective sensors 211 to 215 constituting the sensor stage 210 and each component constituting the rain gauge are operated under the control of the central control stage 270.

The microprocessor 272 may be the core of the central control stage 270. The microprocessor 272 receives the precipitation measurement data and the meteorological observation data through the interface unit 271, calculates and processes the data, and controls each component in accordance with a remote control signal from an external device.

In addition, the microprocessor 272 can be easily controlled by a program that controls each component of the rain gauge by the C language, the basic language, or the like, and does not require a complicated configuration as in the conventional weather observation apparatus. In addition, it accurately analyzes the external control signals and enables remote control and transmission of the analyzed data.

The communication module 273 sets up and processes communication so that each component constituting the rain gauge can be externally controlled, and transmits the precipitation data and the weather observation data measured and processed by the rain gauge of the present embodiment to the outside. Therefore, the central control stage 270 can record the measurement data itself and transmit it to the external device in real time.

In addition, as shown, the communication module is designed to enable wireless control and signal transmission by providing a wireless port so that the wireless port can be controlled as well as a wired port. Therefore, the remote control signal from the outside by wireless or wired is received by the communication module and then converted into a signal that can be recognized by the microprocessor 272, so that remote control is possible. Since the measurement data is converted and transmitted by the communication module 273, the external device can recognize the data. In addition, by connecting additional memory, a lot of data can be stored.

Finally, the power supply unit 274 performs a function of supplying power required for the operation of each component. In the rain gauge of the present embodiment, the apparatus is adapted to convert power into direct current or the like when AC power is applied. In addition, it is designed to measure precipitation irrespective of power supply because it connects power supply device by solar cell so that it can be measured even when power supply is difficult or outdoor no AC power supply.
