Multi-sensor fusion high-precision water level measuring device and method

Abstract

The invention relates to the field of water level measurement, in particular to a multi-sensor fusion high-precision water level measuring device and method.The device comprises a microprocessor, a power module, a first water level sensor and a second water level sensor, and the first water level sensor is an electronic water gauge provided with a water encountering monitoring module; the second water level sensor is a pressure sensor and / or an ultrasonic sensor; the water encountering monitoring module is used for sending a signal for controlling the working mode of the measuring device; when the water level value is not greater than HA, the microprocessor collects a measurement value of the electronic water gauge as a measurement result; and when the water level value is greater than HA, the microprocessor collects a measured value of the second water level sensor and performs filtering estimation processing on the measured value to estimate an optimal measurement result. According to the invention, multiple sensors are deeply fused, the measurement precision is high, the volume miniaturization of equipment is realized, the installation is easy, the maintenance cost is low, the power consumption is low, and the long-time work can be realized.

Description

technical field [0001] The invention relates to the field of water level measurement, in particular to a multi-sensor fusion high-precision water level measurement device and method. Background technique [0002] With the development of the economy, cities are changing with each passing day. The construction of large and medium-sized cities is developing at a high speed by leaps and bounds. The urban circle is also expanding, and smart cities are being built everywhere. In recent years, water accumulation in cities under tunnels, under overpasses, urban roads, and low-lying places caused by heavy rainfall often occurs, and it is becoming more and more serious. In rainy cities, some waterloggings can be as high as 1 meter, and the water level cannot be lowered in a short period of time, which brings inconvenience to people's travel and, in severe cases, leads to the disappearance and death of pedestrians. [0003] At present, there are many different water level gauges on th...
