Abstract

The invention discloses a tunnel ventilation control system based on stable power supplies. The tunnel ventilation control system comprises a power supply module, a plurality of carbon monoxide detection modules evenly distributed in a tunnel, a wind speed detection module, a plurality of first WIFI slave nodes, second WIFI slave nodes, first WIFI relay nodes, second WIFI relay nodes, a WIFI summarizing node, an upper computer, a PLC, a frequency converter, an air supply duct and a draught fan. Each carbon monoxide detection module comprises a carbon monoxide sensor, a signal amplifying circuit and an A / D conversion module which are sequentially connected; and the power supply module comprises a CC2530 chip, an LTC4414 chip, the main power supply, the standby power supply, first to fifth resistors, first to fourth P channel field-effect tubes, a first light-emitting diode and a first capacitor. The tunnel ventilation control system monitors the environment in the tunnel in real time based on the stable power supplies and a WIFI wireless sensor network, and the good air quality in the tunnel is guaranteed.

Description

technical field [0001] The invention relates to the technical field of tunnel ventilation equipment, in particular to a tunnel ventilation control system based on a stable power supply. Background technique [0002] With the rapid development of my country's traffic roads, railway and highway tunnel construction projects are increasing day by day. Due to the complex geographical conditions of our country and the characteristics of the tunnel itself, the tunnel monitoring system plays an extremely important role in the operation and management of the tunnel and the handling of accidents. If advanced monitoring and management measures are not adopted, traffic accidents and traffic jams will easily occur in the case of heavy traffic volume and bad weather. Tunnel monitoring and management has become an important guarantee for the safe and normal operation of vehicles in the tunnel. With the development of computer technology, image processing technology, communication technolo...
