Embodiment Construction

[0016] The present invention will be further described below in conjunction with accompanying drawing:

[0017] Such as figure 1 and figure 2 As shown in the present invention, a subway internal environmental quality online detection system includes an environmental quality measurement unit and a control unit, and the environmental quality measurement unit includes a variety of intelligent sensors connected to the data signal input terminals of the control unit respectively. The smart sensors mentioned above include smart micro-meteorological sensors, particle detectors, carbon dioxide sensors, noise sensors, heat flow sensors, wall temperature sensors and black ball temperature sensors. Multiple smart sensors can send the collected data to The control unit collects and processes, and at the same time, sends its own fault diagnosis information and working status to the control unit at regular intervals. The control unit includes a launch drive circuit, a signal acquisition ...

Abstract

The invention discloses an online detection system for a subway internal environment quality. An environment quality measurement unit includes a plurality of kinds of intelligent sensors which are connected with data signal input ends of a control unit respectively. The intelligent sensors include an intelligent microclimate sensor, a particle detector, a carbon dioxide sensor, a noise sensor, a heat flux sensor, a wall temperature sensor and a black globe temperature sensor. The online detection system for the subway internal environment quality adopts the microclimate sensor so that factors such as temperature, humidity, wind speed and atmospheric pressure and the like can be acquired at the same time and thus the system is more suitable for being installed and used for measurement in a special environment of the subway. A modularized and distributed assembly structure is adopted so that representative detection points can be selected and flexible installation can be carried out according to the special environment and layout in the subway. Subway internal environment quality detection and data application are integrated so that environment quality detection data is more accurate and more diversified in kinds and at the same time, information such as wind-chill index and human body comfort index and the like can be issued at the same.

Description

technical field [0001] The invention relates to an environmental quality detection device, in particular to an online detection system for the internal environmental quality of a subway. Background technique [0002] At present, the subway has become the main tool of urban transportation, and the carbon dioxide, particulate matter index, noise and environmental comfort inside the subway are more and more concerned by the public. The existing subway environmental quality testing mainly uses various hand-held detectors, which have problems such as single content, low precision, and inability to meet online testing. Contents of the invention [0003] The object of the present invention is to provide an online detection system for the internal environmental quality of the subway in order to solve the above problems, which integrates the measurement of temperature, humidity, wind speed, air pressure, particle concentration, carbon dioxide concentration, noise, wall temperature,...
