example 1

[0044] Example 1: In step 1, in tunnel ventilation control, the domain of CO concentration is selected as [150, 300]ppm, and the expected control value is 200ppm. To fuzzify the value of CO concentration, the membership function adopted is Gaussian function, and the deviation of CO concentration is transformed into the discrete universe as {-3, -2, -l, 0, l, 2, 3}.

[0045] Step 2: In tunnel ventilation control, the domain of smoke concentration is selected as [6, 9]km-1, and the control expectation value is 7km-1. To fuzzify the value of smoke density, the membership function adopted is Gaussian function, and the deviation of smoke density is transformed into a discrete universe of {-3, -2, -1, 0, 1, 2, 3}.

[0046] Step 3. Define the fuzzy language variables of CO and smoke concentration deviation respectively as {negative large, negative medium, negative small, zero, positive small, positive medium, positive large}, expressed as {NB, NM, NS, ZO, PS, PM, PB}, NB represents ...

Abstract

The invention discloses a tunnel ventilation energy-saving control system based on fuzzy control and a control method of the system. The control system comprises a center control computer, a fuzzy intelligent controller and a fan control cabinet, wherein the center control computer, the fuzzy intelligent controller and the fan control cabinet are sequentially connected. The input end of the fuzzy intelligent controller is further connected with a CO concentration detector and a smoke concentration detector, the output end of the fan control cabinet is connected with at least one site controller, and the output ends of the site controllers are respectively connected with at least one fan. The tunnel ventilation energy-saving control system based on fuzzy control has the advantages that the system is safe and reliable, man-machine interaction pages are good, operation performance is excellent, the intelligent degree is high, the system is not influenced by network ventilation failure and can independently finish energy-saving operation in normal work conditions, and manual intervention is reduced to the largest extent. The system can meet the control function requirement, and is effectively compatible with multiple communication protocols and good in compatibility and expandability.

Description

technical field [0001] The invention relates to the technical field of tunnel ventilation energy-saving control, in particular to a fuzzy control-based tunnel ventilation energy-saving control system and a control method thereof. Background technique [0002] With the continuous development of my country's expressways, expressway construction continues to expand to mountainous areas, and expressways, especially expressway tunnels, are becoming more and more long. Since the tunnel is a relatively closed area, the exhaust gas emitted by cars when driving in it does not diffuse into the atmosphere with natural wind and traffic wind like other road sections. Especially for tunnels with long distances and heavy traffic volume, natural wind and traffic wind have poor ability to replace the air in the tunnel, so mechanical ventilation must be adopted, otherwise the carbon monoxide, nitrogen oxides, hydrocarbons, and sulfurous acid gases emitted by cars Harmful substances such as s...
