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 its control method. The control system includes a central control computer, a fuzzy intelligent controller and a fan control cabinet connected in sequence, wherein the input end of the fuzzy intelligent controller is also connected to There are CO concentration detectors and smoke concentration detectors, at least one field controller is connected to the output end of the fan control cabinet, and at least one fan is connected to the output ends of the field controllers. The beneficial effects of the present invention are: the tunnel ventilation energy-saving control system based on fuzzy control described in the present invention is safe and reliable, has good human-computer interaction pages, excellent operation performance, high intelligent program, is not affected by network ventilation failure, and the system can be independent Complete energy-saving operation under normal working conditions to minimize manual intervention. In addition to meeting the requirements of control functions, it can also be effectively compatible with various communication protocols, and has good 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...
