Description

technical field [0001] The invention belongs to the technical field of tunnel construction ventilation, and in particular relates to an energy-saving operation control system and method of a tunnel construction ventilation system. Background technique [0002] Tunnel construction generally adopts double-head or multi-face excavation of a tunnel, multi-process operations, gradual extension, and finally breakthrough. During construction, due to drilling, explosive blasting, slag loading, sprayed concrete, exhaust emissions from internal combustion machinery and transport vehicles, a large amount of toxic and harmful gases and dust will be generated, making the air in the narrow space in the tunnel very dirty and making the working environment harsh. Working in this environment will cause great harm to the health of construction workers, such as carbon monoxide poisoning, breathing difficulties, and reduced work efficiency. During the construction process, it is necessary to s...

Problems solved by technology

[0015] However, in domestic tunnel construction ventilation, most fans do not use motor frequency conversion speed regulation technology, and do not adjust the fan speed to make the fan output air volume adapt to the air volume required by different working conditions, resulting in energy waste

A small number of fans are equipped with frequency converters. Although the frequency converter can be used to change the frequency of the fan power supply to adjust the fan speed, the adjustment is done manually by the staff. Since the tunnel construction ventilation system is a nonlinear and multi-interference system, the system’s The relationship between the wind speed and the speed of the fan is not linear, and is affected by many factors, so that the potential of using frequency conversion speed regulation technology to realize energy saving in tunnel construction has not been fully utilized
