Abstract: A pipeline-integrated measuring device includes a thrust fixed frame, a measuring fixed frame, a measuring moving frame and strain spokes. The measuring fixed frame is fixed on the thrust fixed frame and is connected to the measuring moving frame by means of the strain spokes. A first propellant supply connecting nozzle is arranged on the measuring fixed frame and is used to be in communication with a propellant supply pipeline on a test bench; propellant supply channels are arranged in the strain spokes; a second propellant supply connecting nozzle is arranged on the measuring moving frame and is used to be connected to an engine inlet pipeline; first sensors, second sensors and third sensors are arranged on the strain spokes; and the first sensors, the second sensors and the third sensors are arranged at maximum strain force positions in axial directions and lateral directions of the strain spokes respectively.

Abstract: A method for determination and isolation for abnormal sub-sensors in a multi-core sensor. It can be intelligently determined whether the reason for an abrupt dramatic change in sensor data is a sensor fault or sudden pollution, so as to increase data reliability. A data online rate is increased if a repair can be performed via automatic determination when a device fault occurs, which has significant value for continuous monitoring required for a haze treatment operation. In addition, human and material resources for device maintenance may be saved, thereby reducing waste.

Abstract: The disclosure provides a method for selecting bus lines through collaborative monitoring of taxis and buses. The method focuses on road network of an urban area, by installing air pollution detection equipment on the mobile monitoring vehicles, to monitor air quality of the urban area. The method includes establishing a curve model of monitoring times for the taxis; establishing a curve model of monitoring times for each bus line, in which its horizontal axis is consistent with the horizontal axis of the taxi detection frequency curve model; assigning monitoring times to the corresponding road section unit; sorting each bus line according to the numbers of undetected segments the each bus line covers; and selecting the bus routes participating in collaborative monitoring.

Abstract: A handrail belt tension device is provided for an escalator having a truss and an annular handrail belt rotatable relative to the truss. The handrail belt tension device includes: a base plate on which a roller for supporting the handrail belt is provided, and a guiding mechanism which is fixed to the truss. The base plate is connected to the guiding mechanism, and rotatable and translatable relative to the guiding mechanism so as to adjust the handrail belt by the base plate thereby the handrail belt can be in a well tensioned status. The handrail belt tension device ensures that the tension device is installed in a more accurate position, making it easier to adjust the tensioning force of the handrail belt, reducing the time for adjusting the handrail belt, and increasing the service life of the handrail belt.
