Description
Technical field
The present invention relates to environment measuring technology, the skill put more particularly to a kind of subway tunnel testing natural ventilation rate
Art.
Background technology
Subway energy conservation need to carry out long term monitoring to the natural ventilation rate of station.By subway train pressure shadow out of the station
Ring, subway gravity-flow ventilation is mainly that the Piston Action Wind of subway concourse is passed in and out by walkway, and wind direction, which can then be divided into, to enter the station, be calm, be outbound
Three kinds of states, these three wind direction states regularly can alternately change according to subway train in/out station situation.
Existing wind quantity test device is designed for ground environment, existing in order to tackle the ground environment of complexity
Wind quantity test apparatus structure is all more complicated, and hardware cost is high, it is low there is testing efficiency when subway tunnel is tested the problem of.
The content of the invention
For defect present in above-mentioned prior art, the technical problems to be solved by the invention be to provide a kind of hardware into
This is low, and the subway tunnel testing natural ventilation rate of testing efficiency is put.
In order to solve the above-mentioned technical problem, a kind of subway tunnel testing natural ventilation rate provided by the present invention is put, its
It is characterised by：Including master controller, memory module, air measuring instrument, wind direction measurement seat；
A rotatable wind direction indicator board is vertically arranged on the wind direction measurement seat, the rotating shaft of wind direction indicator board is vertical, wind direction measurement
Seat is provided with two proximity switches that can be triggered by wind direction indicator board, and two proximity switches are laid in wind direction indicator board respectively
The left and right sides；
The master controller interconnects with memory module, and the measurement data output port of air measuring instrument is connected to the data of master controller
Port is gathered, two proximity switches that wind direction is measured on seat are coupled with two wind direction signals input ports of master controller.
Subway tunnel testing natural ventilation rate provided by the invention is put, and utilizes the cooperation of wind direction indicator board and proximity switch
To detect the wind direction of subway tunnel, in conjunction with the air speed data measured by air measuring instrument, leading to naturally for subway tunnel is calculated
Air quantity, its is simple in construction, and hardware cost is low, and method of testing is simple, and testing efficiency is high.
Brief description of the drawings
Fig. 1 is the structural representation that the subway tunnel testing natural ventilation rate of the embodiment of the present invention is put；
Fig. 2 is the structural representation of the wind direction measuring unit during the subway tunnel testing natural ventilation rate of the embodiment of the present invention is put
Figure.
Embodiment
Embodiments of the invention are described in further detail below in conjunction with brief description of the drawings, but the present embodiment is not used to limit
The system present invention, every similar structure using the present invention and its similar change, all should be included in protection scope of the present invention, the present invention
In pause mark represent the relation of sum.
As Figure 1-Figure 2, a kind of subway tunnel testing natural ventilation rate that the embodiment of the present invention is provided is put, and it is special
Sign is：Including master controller 2, memory module 3, air measuring instrument 1, wind direction measurement seat 4；
A rotatable wind direction indicator board 5 is vertically arranged on the wind direction measurement seat 4, the rotating shaft of wind direction indicator board 5 is vertical, and wind direction is surveyed
Amount seat 4 is provided with two proximity switches 6 that can be triggered by wind direction indicator board 5, and two proximity switches 6 are laid in wind direction and referred to respectively
Show the left and right sides of plate 5；
The master controller 2 interconnects with memory module 3, and the measurement data output port of air measuring instrument 1 is connected to master controller 2
Data collection terminal mouth, two proximity switches 6 that wind direction is measured on seat 4 are coupled with two wind direction signals input of master controller 2
Port.
The embodiment of the present invention is applied to the natural ventilation rate of measurement subway tunnel, and its method of testing is as follows：
, will for the natural ventilation rate in subway tunnel is uniform, air flow direction is horizontal and wind direction imports and exports situation about alternately flowing
Air measuring instrument is positioned over the upside steady air current position of subway tunnel, and cause the wind speed probe 11 of air measuring instrument vertical and
Test port is perpendicular to wind direction（That is the direction out of the station of train）, air measuring instrument pass through wind speed probe 11 measure subway tunnel in
Wind speed；
When having train in/out station, Piston Action Wind can be produced in subway tunnel, now wind direction indicator board 5 is in the presence of Piston Action Wind, meeting
Deflect towards one of proximity switch 6, closed so as to trigger the proximity switch 6, and another proximity switch 6 is then in disconnected
Line state；
Wind speed of the master controller 2 according to measured by air measuring instrument, and the wind direction representated by two proximity switches 6, calculate ground
The air force of Tie Tong road, and result of calculation is stored in memory.
