Abstract

An automatic rainfall monitoring device for subway, mainly composed of a microprocessor, a rainfall sensor and its signal conditioning circuit, an A / D conversion circuit, and a stepping motor drive interface circuit. The device can automatically adjust the opening of the anti-flooding valves installed in each smoke exhaust and ventilation hole in real time according to the amount of rainwater flowing or recharging into the subway station and tunnel. Water problems, reduce the running time and power consumption of drainage pumps, and optimize the ventilation parameters to keep the ventilation of the subway environment at its best. The device can also summarize the on-site conditions such as the amount of rainwater in each smoke exhaust and ventilation hole and the opening of the anti-flooding valve to the upper computer in the monitoring room in real time through a wired or wireless communication network for further processing. The invention has the advantages of convenient installation and use, good reliability, low price and the like, and is very suitable for the automatic control and centralized monitoring of the smoke exhaust and the opening of ventilation holes in buildings such as subways, tunnels and warehouses.

Description

technical field [0001] The invention relates to an automatic rainfall monitoring device for subways or tunnels. Background technique [0002] The stations and tunnels of subway projects are mostly below the ground level. In addition to being affected by the seepage and soaking of groundwater in the rock-soil medium, rainfall can drift into the subway stations and tunnels through smoke exhaust and ventilation holes. When the flood water level is higher than The air pavilions, smoke exhaust and ventilation holes of the subway station can also be recharged into the subway station and tunnel when the elevation is high, so that the decoration materials will be mildewed, and the electrical lines, communication equipment and electronic components will be damaged and malfunctioned due to moisture and water, causing engineering accidents. In addition, the rainwater drifting and recharging also increased the humidity inside the subway, causing chest tightness and discomfort to passeng...
