Remote management platform used for air conditioner

Abstract

The invention discloses a remote management platform used for an air conditioner. The remote management platform comprises a plurality of sensor nodes, a controlling main unit, an upper computer, a lower computer and a central air-conditioner terminal which are connected with the lower computer. Each sensor node is provided with a temperature sensor, a humidity sensor, an air quality sensor and a wireless module 24L01. The multiple sensor nodes converge into one or a plurality of sink nodes. Teletransmission is achieved between the sink nodes and the controlling main unit through the Ethernet. Each sink node comprises a wireless module 24L01 and a main controlling chip STM32F103VET6 and further comprises a solid voltage regulator and a compressor power measuring module. The compressor power measuring module comprises an instrumentation amplifier, an ADC switching circuit and a measuring processor. According to the motoring platform used for the central air conditioner, environment variable parameters such as the temperature, humidity and air quality of indoor space can be monitored in real time, the output power of the central air-conditioner is adjusted to be matched with an actual load, and accordingly, on-demand point-fixed and directional adjusting is achieved.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to a remote management platform for air conditioners. Background technique [0002] At present, due to the lack of advanced technical support, domestic central air-conditioning systems basically adopt the traditional constant flow control method, that is, the air-conditioning chilled water flow, cooling water flow and cooling air volume are all constant. Generally, the central air-conditioning system is designed and selected according to the highest temperature in local history, and a 15-20% margin is reserved. In this way, during normal use, even in the hottest season, the central air conditioning system is not fully operating at full capacity. In the water transfer system of the central air conditioner, the capacity of the chilled water pump and the cooling water pump is also selected according to the maximum design load of the building. As a result, the actual operation situatio...

Problems solved by technology

However, the heat load of the entire building will change dynamically with changes in seasons, day and night, and user needs. The actual heat load of the central air conditioner is far lower than the design load most of the time, and the waste of resources caused by this is also very serious.
