The invention discloses a voltage data collection device for fire prevention and control of fire safety scientific engineering. The voltage data collection device for fire prevention and control of the fire safety scientific engineering comprises a plurality of externally-arranged micro-differential-pressure sensors, a signal collector and a data collection device, wherein the externally-arrangedmicro-differential-pressure sensors converts pressure signals of a pitot tube flowmeter into voltage data; the signal collector collects measurement results of the externally-arranged micro-differential-pressure sensors, and the externally-arranged micro-differential-pressure sensors are in communication connection with the signal collector through connecting lines; and the data collection deviceis used for data storage and analysis, and the signal collector is in communication connection with the data collection device through a data bus. The voltage data collection device for fire prevention and control of the fire safety scientific engineering can improve the defects in the prior art and improve the fire early warning precision.
Description
technical field [0001] The invention relates to an electronic information collection device, in particular to a voltage data collection device and method for fire safety scientific engineering fire prevention and control. Background technique [0002] With the development of fire prevention and control technology, using pitot tube flowmeter to detect the flow of flue gas, and using automatic equipment to monitor and warn the flow of flue gas in real time has become a common system in various key areas of fire prevention and control. However, due to the inevitable interference in the process of signal collection and transmission, false alarms or no alarms often occur in fire early warning, and the accuracy of early warning is not good. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a device and method for collecting voltage data for fire prevention and control in fire safety scientific engineering, which can solv...
