Abstract

An automatic rainfall amount monitoring device for subway is mainly composed of a microprocessor, a rainfall amount sensor and a signal processing circuit thereof, an A / D converting circuit and a drive interface circuit of a stepping motor. The device can automatically adjust the opening of the flooding proof valve disposed at each smoke discharging and ventilating opening in real time based on the rainfall amount drip into or back pouring into the subway station and tunnel, it not only can solve the water input problem of the subway station and tunnel, reduce the running time and power consumption of the water discharge pump, but also can optimize the ventilation parameter and hold the ventilation status of the subway environment at best status. The device also can summarize the field situation such as the rainfall amount of each smoke discharging and ventilating opening and the opening of the flooding proof valve by wired or wireless communication network in real time to an upper computer of a monitoring chamber for further process. The invention has the advantage of convenient in assembly and use, good reliability and low cost, and is adapted for the automatic and centralize monitor of the opening of the smoke discharging and ventilating opening of the buildings such as subway, tunnel and store house.

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...
