Underground chamber fire protection system construction method

Abstract

The present invention provides an underground chamber fire protection system construction method. According to the method, a wireless sensor network is adopted to carry out fire hazard monitoring. A sensor network node and a monitoring center server are adopted; the sensor network node is arranged at a measured position and is connected with the monitoring center server through a local area network; the monitoring center server provides data services or sends early warning information to remote users through a network; and the sensor network node includes a sensor network positioning module which carries out positioning through adopting an ellipse localization method, a sensor constraining module used for constraining the cost and energy of the sensor, a self power supply module which supplies energy through adopting a dye-sensitized photovoltaic cell, and a data correction module. The method of the invention has the advantages of long service life and high monitoring precision. With the method adopted, the positioning speed of the sensor network node is increased, and the cost and energy of the sensor are constrained, and monitoring cost can be saved to the greatest extent.

Description

technical field [0001] The invention relates to the field of fire protection, in particular to a construction method of a basement fire protection system. Background technique [0002] Fire refers to the disaster caused by burning out of control in time and space. Among all kinds of disasters, fire is one of the main disasters that most frequently and commonly threatens public safety and social development. At present, the automatic fire alarm system is mainly based on temperature detection and smoke detection. Judgment is made based on the data information collected by the sensor, and if it exceeds the preset threshold, an abnormal alarm will be issued. With the passage of monitoring time and the increase of the amount of sensing data, there are great difficulties in the management of sensors and the organization of sensing data, and the data collected by sensor network nodes must be combined with their positions in the measurement coordinate system Information makes sens...

Problems solved by technology

[0003] In addition, the sensors used for monitoring consume a lot of energy and are easily affected by the environment such as temperature, which reduces the accuracy of the data measured by the sensors and further affects the accuracy and cost of fire monitoring.
