[0002] Rail transit is a common means of transportation for people's daily travel, and the quality of the rail transit environment directly affects people's experience; the rail transit environment is greatly affected by the ventilation system, especially the wind pressure in the ventilation system, and the abnormal wind pressure not only It will affect the environment of rail transit, bring a poor experience to the passengers, and at the same time easily cause damage to the equipment, affecting the service life of the equipment, resulting in unnecessary increase in maintenance costs
[0003] At present, the existing wind pressure detection methods mainly use instruments to measure pressure and rely on manual detection, which not only requires a lot of manpower and material resources, but also has a low level of automation; at the same time, only considering the wind pressure, it cannot be based on the actual environment. Adapt measures to local conditions, resulting in inaccurate maintenance strategies in the later period

Embodiment Construction
[0031] The present invention will now be described in further detail with reference to the drawings. These drawings are all simplified schematic diagrams, which merely illustrate the basic structure of the present invention in a schematic manner, so they only show the structures related to the present invention.
[0032] Aiming at the problems existing in the wind pressure detection and maintenance process of the existing rail transit ventilation system, the present invention proposes a method for detecting the wind pressure of the rail transit ventilation system. The method is implemented based on a preset detection system. The system includes at least a detection device and a management device. The management equipment can be divided into station hall management equipment and central management equipment. Depending on the location, the above management equipment has different control rights. And the upper-level management equipment maintains and manages the lower-level manageme...

The invention relates to a method for detecting wind pressure of a rail transit ventilation system, and the method can consider environmental information while detecting wind pressure, determine an abnormal state according to the environmental information and a wind pressure coefficient, and then select a suitable transmission method, thereby guaranteeing the stable transmission of data while ensuring accuracy, improving the degree of automation of wind pressure detection, ensuring that maintenance personnel can formulate maintenance strategies based on the actual situation of wind pressure detection, improving the efficiency and accuracy of maintenance, reducing costs and improving traveler experience.
Description
Technical field [0001] The invention relates to a method for detecting the wind pressure of a rail transit ventilation system. Background technique [0002] Rail transit is a common means of transportation for people’s daily travel, and the quality of the rail transit environment directly affects people’s experience; the rail transit environment is affected by the ventilation system, especially the wind pressure in the ventilation system. The abnormal wind pressure is not only It will affect the environment of rail transit and give passengers a poor experience. At the same time, it is easy to cause damage to the equipment, affect the service life of the equipment, and cause unnecessary maintenance costs. [0003] At present, the existing wind pressure detection methods mainly use instruments to measure pressure and rely on manual methods for detection. This not only requires a lot of manpower and material resources, but also has a low level of automation; at the same time, it only ...
