Intelligent tunnel air supply and exhaust system based on DSP automatic control technology

Abstract

The invention relates to the technical field of tunnel ventilation, in particular to an intelligent tunnel air supply and exhaust system based on the DSP automatic control technology. The intelligent tunnel air supply and exhaust system based on the DSP automatic control technology comprises a tunnel and connecting hoops, wherein the lower end face of the tunnel is fixedly connected with the uniformly distributed connecting hoops; the lower parts of the connecting hoops are fixedly connected with protection pipelines; uniformly distributed sensors are fixedly connected to the lower end surface of each protection pipeline; a controller is fixedly connected to the upper end surface of each protection pipeline; a fixing mechanism is fixedly connected to the right end surface of each protection pipeline; and a protection mechanism is fixedly connected to the right end surface of each fixing mechanism. According to the intelligent tunnel air supply and exhaust system based on the DSP automatic control technology provided by the invention, through the arrangement of a threaded rod, a threaded cylinder, guide rail grooves and guide plates, when the situation that air in a tunnel is foul is monitored through the sensors, a rotating motor is started to drive the threaded rod to rotate at the moment, the threaded rod drives the threaded cylinder to move, then a large fan is made to move, and at the moment, through the lifting of the large fan, the foul air in the tunnel is effectively exhausted, so that the ventilation effect is better.

Description

technical field [0001] The invention relates to the technical field of tunnel ventilation, in particular to an intelligent tunnel air supply and exhaust system based on DSP automatic control technology. Background technique [0002] With the continuous development of expressways in our country, expressway construction continues to expand to mountainous areas, and expressway tunnels are becoming more and more long. Since the tunnels are relatively closed areas, the exhaust gas emitted by cars when driving in them is not as In other road sections, it will diffuse into the atmosphere with natural wind and traffic wind, especially for tunnels with long distances and heavy traffic. Hazardous substances such as hydrocarbons, sulfurous acid gas, and smoke and dust will cause air pollution in the tunnel. When the mass concentration of CO is high, it will endanger people's health; smoke and dust will deteriorate the vision and affect the sight of drivers. Bring safety hazards to dri...

[0002] With the continuous development of expressways in our country, expressway construction continues to expand to mountainous areas, and expressway tunnels are becoming more and more long. Since the tunnels are relatively closed areas, the exhaust gas emitted by cars when driving in them is not as In other road sections, it will diffuse into the atmosphere with natural wind and traffic wind, especially for tunnels with long distances and heavy traffic. Hazardous substances such as hydrocarbons, sulfurous acid gas, and smoke and dust will cause air pollution in the tunnel. When the mass concentration of CO is high, it will endanger people's health; smoke and dust will deteriorate the vision and affect the sight of drivers. Bring safety hazards to driving. In order to solve the ventilation problem in the tunnel, a tunnel ventilation system is usually installed in the tunnel. The existing tunnel ventilation system generally uses a fan installed on the top of the tunnel for ventilation, which cannot adjust the height of the fan, and the fan When starting the ventilation function, it can only blow the air in the upper layer of the tunnel, while the air circulation in the lower layer is limited, and its ventilation effect is not good. Therefore, a smart tunnel based on DSP automatic control technology is proposed to solve the above problems Tunnel air supply and exhaust system
