Embodiment Construction

[0029] The present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.

[0030] The present invention creates an integrated system with a comprehensive monitoring system as a platform, and realizes the start-stop and frequency adjustment of various fans in the subway through communication protocols and background algorithms. The energy-saving strategies of various fans and the realization of system software will be discussed below Two aspects are described in detail.

[0031] 1.1 Fan Energy Saving Strategy

[0032] Fans on the entire subway line are divided into heat exhaust fans, large system fans, tunnel exhaust fans, and jet fans. According to energy consumption statistics, the most important normally-on fans are heat exhaust fans and large-scale system fans, while jet fans, tunnel exhaust fans and other fans in the tunnel section will only be activated under working conditions such as blockage and fire, and ar...

Abstract

The invention discloses a subway multi-site fan energy saving method, and provides a station-fan timed start and stop time and start and stop frequency control method applied to urban railway transit. The method is characterized by comprising the steps of selection of energy-saving strategies and architecture of a linkage system, wherein the energy-saving strategies comprise a fan frequency-conversion energy-saving strategy which comprises the process of adjusting frequency of a heat removal fan in a fully dynamic mode according to train real-time station arrival information and a fan start and stop energy-saving strategy which comprises the process of starting and stopping station large-system fans by analyzing a planned train timetable, and the architecture of the linkage system comprises a front-stage HMI image, a data structure, a back-stage program and an interface protocol. According to the method, fan energy consumption can be reduced, and green and energy-saving effects can be achieved. A subway integrated monitoring system serves as a master control platform, a signal-professional train timetable and a train real-time status serve as bases, a time recursion shoot algorithm and a universal linkage interface program serve as drives, and therefore the method can be applied to environmental control of various railway transit stations by means of a series of detailed linkage debugging.

Description

technical field [0001] The invention discloses a method for timing start-stop time and start-stop frequency of a platform fan applied to an urban rail transit, and in particular relates to an energy-saving method for a subway multi-site fan. Background technique [0002] With the popularization of the subway, the energy consumption of the subway has gradually entered people's field of vision. According to the statistical analysis of energy consumption in most cities with subways in China, in the actual operation process, the energy consumption of the environmental control system (BAS) is all It is the highest in the subway system, and in several subsystems of the environmental control system, such as: wind system, water system, etc., the energy consumption of air conditioning and mechanical ventilation (fan) accounts for 50% of the entire environmental control system, accounting for 50% of the energy consumption of the entire subway system. It accounts for a considerable pro...
