Embodiment 1

[0033] Embodiment 1: The principle of this embodiment judges the positional relationship between the corresponding RF electronic tag and the water surface by the readable RF electronic tag, and calculates the current water level in combination with the installation position information of each RF electronic tag.

[0034] According to the situation of the water level monitoring site, determine the total number of radio frequency electronic tags to be installed at this water level monitoring point as K, K is a natural number greater than or equal to 2, and make their spacing equal to D in the direction perpendicular to the horizontal plane , D is any value greater than the length of the radio frequency electronic tag itself, the altitude of the highest radio frequency electronic tag is H, after determining the specific installation location information of the radio frequency electronic tag that needs to be installed, the data processing terminal allocates data for each radio frequ...

Embodiment 2

[0037] Embodiment 2: The principle of this embodiment judges the positional relationship between the corresponding RF electronic tag and the water surface by detecting the change in the energy intensity of the RF signal sent by the RF electronic tag received by the RF reader, combined with the installation position of each RF electronic tag The information calculates the current water level.

[0038] When the working state and position relationship between the RF reader and the RF electronic tag are fixed, the main factor for the change of the RF signal energy intensity of the RF electronic tag received by the RF reader is the depth of the RF electronic tag being submerged in water. When the radio frequency electronic tag is far away from the water surface, the radio frequency reader detects that the radio frequency signal energy intensity of the radio frequency electronic tag is basically unchanged. The RF signal energy strength continues to decrease with increasing depth. S...

Abstract

The invention relates to a water level monitoring system using a radio frequency communication method. The system comprises at least two groups of radio frequency electronic tags, radio frequency electronic tag attachments for mounting the radio frequency electronic tags, a radio frequency reader and a data processing terminal, and is characterized in that the radio frequency electronic tag attachments are perpendicular to the water level; the radio frequency electronic tags are arranged regularly in the direction perpendicular to the water level, wherein at least one group of tags are located below the water level; the radio frequency reader is mounted within effective identification range of the radio frequency electronic tags to keep radio frequency communication between the radio frequency reader and the radio frequency electronic tags; and the data processing terminal at least comprises a program control module, a data storage module and a communication interface module for implementing calculation and storage functions. The water level monitoring system using the radio frequency communication method has the following beneficial effect that 1. equipment installation is simplified; and 2. multipoint water level monitoring is convenient to implement.

Description

technical field [0001] The invention relates to the technical field of monitoring, in particular to the technical field of water level monitoring. Background technique [0002] The existing inventions of water level monitoring technology mainly apply the principles of acoustics, electricity and mechanics, which can obtain high measurement accuracy, but the equipment is relatively complicated. Among them, ultrasonic water level monitoring uses the reflection of ultrasonic waves. By measuring the delay time of ultrasonic waves emitted from the transmitting end and received by the receiving end after the reflected ultrasonic waves are returned, the distance from the measuring device to the water surface can be calculated. Electrical water level monitoring can also measure water level using electrodes, making use of the conductivity of water. In addition, mechanical water level monitoring can also realize water level detection by using the buoyancy and pressure of water. The e...
