Embodiment Construction

[0032] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be noted that the following embodiments are intended to facilitate the understanding of the present invention, but do not limit it in any way.

[0033] like figure 1 As shown, an energy-saving method for air conditioners in subway electrical equipment rooms based on infrared heat source monitoring. First, through an infrared-based real-time monitoring module for the temperature of subway electrical equipment, a fixed infrared sensor connected to an industrial computer and a mobile infrared sensor carried by a smart car are used. Sensors are used for fixed and mobile temperature monitoring of electrical equipment such as rectifier transformers, gateway cabinets, and PLC control cabinets in the subway electrical equipment room.

[0034] Then, through the air-conditioning intelligent temperature control module based on the heat source deman...

Abstract

The invention relates to metro electrical equipment room air conditioner energy-saving system and method based on infrared heat source monitoring. The energy-saving system comprises a main control unit, and a temperature real-time monitoring module and an air conditioner intelligent temperature control module connected with the main control unit, wherein the temperature real-time monitoring modulecomprises a fixed type heat source monitoring platform and a movable type heat source monitoring platform, and is used for monitoring temperature information of electrical equipment in real time andsending the acquired temperature information to the main control unit; and the air conditioner intelligent temperature control module comprises an equipment cooling model database and is used for receiving the temperature information sent by the main control unit, analyzing, and outputting a cooling parameter selection scheme matched with a heat source cooling demand. By utilizing the metro electrical equipment room air conditioner energy-saving system and the method based on infrared heat source monitoring provided by the invention, the unnecessary output of the electrical equipment room airconditioner cooling capacity can be reduced, so that energy conservation of an air conditioner is realized.

Description

technical field [0001] The invention belongs to the field of energy saving of air conditioners for subway electrical equipment, in particular to an energy saving system and method for air conditioners of subway electrical equipment rooms based on infrared heat source monitoring. Background technique [0002] At present, China has become the fastest-growing country in the rail transit industry in the world. It is estimated that by 2020, 40 cities across the country will build underground rail transit, with a total planned mileage of 8,000 kilometers. According to reports, in 2017 alone, the power consumption of underground rail transit was more than 12 billion kwh, and the trend of energy consumption is increasing year by year. It is estimated that by 2020, the annual power consumption of rail transit nationwide will reach 48.6 billion yuan. The traction and power system consumes 44% of the electricity, but this part cannot achieve a lot of energy saving. The second place is...
