Description

High reliability water level detecting device

This creation is about a high-reliability water level detecting device, especially a water level detecting device that effectively prevents external atmospheric pressure interference and malfunctions.

Due to its subtropical monsoon climate and tropical monsoon climate, Taiwan is often subjected to severe meteorological storms such as typhoons and fronts. It often has extremely heavy rain or super heavy rain, which means that the rainfall is reduced in a short time, which makes the river easy to skyrocket. In addition to causing various disasters, in order to prevent disasters, most of them will set up water level sensors on the riverside to detect the water level of the river at any time, so as to facilitate the people to deal with disasters that may occur in advance.

The water level sensor can be roughly divided into a floating ball type, a pressure type, an ultrasonic type and a laser wave type. The more common one is a pressure type water level sensor, which mainly detects the current internal pressure value of the air pressure detecting tube, and utilizes The air pressure value is directly converted into the water level in the detection tube, and is generally used in the field of water level monitoring because of its simple use and low cost.

However, although this type of detection method is very practical, it is easy to change rapidly due to the external atmosphere. For example, when a low air pressure (such as a typhoon) or a high air pressure strikes, the air pressure in the air pressure detecting tube changes to cause a malfunction (false alarm).

Therefore, how to improve the pressure type water level detecting device to avoid the external environment interference and malfunction is a problem that the creator is eager to solve.

The main purpose of this creation is to provide a high-reliability water level detecting device, which is provided with a large-pressure sensor for eliminating the external atmosphere from interfering with the air pressure detecting tube, that is, using the atmospheric pressure sensor to sense the external atmospheric pressure as a water level. The person who senses the device air pressure standard value (starting value).

In order to achieve the above object, the present invention provides a high-reliability water level detecting device, which comprises: a water level sensing device having a gas pressure detecting tube, at least one atmospheric pressure sensor for sensing an external air pressure, and a discriminating mode The water level sensing device is configured to sense the air pressure value in the air pressure detecting tube, and the determining module is configured to use the atmospheric pressure value measured by the atmospheric pressure sensor as a standard value (starting value) of the air pressure, The discriminating module compares the air pressure standard value with the air pressure value provided by the water level sensing device, and can further calculate the water level height in the air pressure detecting tube, so that the interference due to the extreme changes of the external atmosphere can be effectively eliminated. The air pressure value in the air pressure detecting tube.

According to the above main features, the air pressure sensor and/or the water level discriminating module are disposed inside a waterproof and permeable box.

In more detail, the air pressure detecting tube 201 of the water level sensing device 20 changes the air pressure in the air pressure detecting tube 201 to change the actual air pressure by using the rising water level. The water level sensing device 20 causes the detected air pressure value to be transmitted to the discrimination module 30.

The main purpose of the present invention is to add a large-pressure sensor 10 for detecting the current atmospheric pressure as a standard value (starting value) of the air pressure, and transmitting the standard value of the air pressure to the discriminating module 30. The discriminating module 30 compares the air pressure standard value with the air pressure value provided by the water level sensing device 20 , and further calculates the water level height in the air pressure detecting tube 201 , thereby effectively eliminating the external The dramatic change in the atmosphere interferes with the pressure value in the air pressure detecting tube 201 .
