Abstract

The invention provides a method for unattended fireproof door control in an electric power tunnel. The control method comprises the steps that smoke concentrations and temperatures within a preset distance in front and rear directions of a fireproof door are detected; when the smoke concentration and the temperature reach preset values, the fireproof door will be closed, and polling equipment will move to and approach a fire disaster site; if a trigger signal is detected for the first time, the polling equipment could be deemed to reach a key point position near the fireproof door, and the fireproof door will be opened, so the polling equipment could pass and enter the fire disaster site; and if the trigger signal is received again or delay time is reached, the polling equipment could be deemed to have entered the fire disaster site, and the fireproof door will be closed, so the polling equipment could start firefighting.

Description

technical field [0001] The invention relates to monitoring technology, in particular to an unattended fire door control system and method for an electric power tunnel. Background technique [0002] With the upgrading of the urban power system, the previous ground pole or iron tower power transmission mode has gradually been transformed into an underground power tunnel power supply mode. This mode has many advantages such as convenient inspection, strong resistance to severe weather disasters, and easy maintenance. It is expected that in the next period of time, the power supply method of electric tunnel will be vigorously promoted and widely used. [0003] With the construction of power tunnels, the supporting power tunnel inspection equipment is gradually being promoted. At present, the power tunnel inspection equipment in the industry already has the functions of fire source identification and initial fire disposal. At the same time, due to the fire control requirements o...
