Description

Data acquisition method based on TCP communication and related equipment Technical Field The application relates to the field of intelligent transmission and collection of sensor data, in particular to a data collection method based on TCP communication and related equipment. Background In the fields of building and industrial automation and environmental monitoring, real-time acquisition and analysis of temperature and humidity data are the basis for realizing intelligent environmental control and energy-saving management. In the related technology, the system densely distributes temperature and humidity sensors in each key area in the building, and gathers the acquired data to a central controller in real time through a wired or wireless network. The central controller compares the real-time temperature readings from the occupied zones with preset comfort target values and executes zone control logic to dynamically adjust the cool/heat output of the air conditioning end units (e.g., fan coils or variable air boxes) in each zone in order to maintain the temperature of each zone within a set range. However, the temperature and humidity of different time periods are affected differently by the sun, and in order to capture the rapid temperature rise of the region subject to direct sunlight, the related art generally sets a relatively short global polling period. Low value repetitive polling may occur in areas not affected by solar radiation. And redundancy and waste of overall operation resources of the system are caused.
