Problems solved by technology

The technology of this equipment is simple, but there are often disadvantages such as false positives and false positives. For example, when the sprinkler touches the electrode, it will also trigger the alarm.
In addition, the electrodes are prone to aging and cannot function properly when water accumulates

Abstract

The invention discloses a city underground tunnel water level early warning apparatus. The apparatus comprises a first portion and a second portion; information is transmitted between the first portion and the second portion through a wireless GPRS system; the first portion is arranged in an underground tunnel and comprises an information acquisition portion and an information processing portion; the information processing portion comprises a single-chip microcomputer; the information acquisition portion comprises a rainfall sensor, a water level sensor and a circuit connecting line, and the rainfall sensor and the water level sensor are respectively connected with the circuit connecting line and the single-chip microcomputer; the second portion is placed at the inlet of the underground tunnel and comprises an information display portion; and the information display portion comprises a wireless controller, an audible-visual annunciator, an LED display screen and a circuit connecting line, and the audible-visual annunciator and the LED display screen are respectively connected with the wireless controller through the circuit connecting line. According to the invention, by use of the city underground tunnel water level early warning apparatus, the water level in a tunnel bridge can be accurately detected and displayed, reliable information is provided for vehicles entering the tunnel bridge, and the safety of the vehicles and personnel is guaranteed.

Description

technical field [0001] The invention relates to the field of water level measurement, in particular to a water level early warning device for urban underground tunnels. Background technique [0002] With the development and construction of cities, more and more underground passages or tunnels are built in the urban road network. The expansion of underground space utilizes the three-dimensional space in the city to a certain extent, and relieves the traffic pressure in the city. Extreme rainstorms in cities have occurred frequently in recent years, and the resulting waterlogging disasters are extremely harmful to cities. Underground projects such as underground tunnels are particularly serious due to low terrain and insufficient drainage. [0003] In response to water accumulation disasters in underground tunnels, some water level warning equipment has been put into use in the market. When the water level rises to the point where it touches the electrode, the warning light w...
