Portable load data acquisition system and method

Abstract

The present invention provides a portable load data acquisition system and method. The portable load data acquisition system comprises a load interface and a power supply, and the load interface is electrically connected with a sampling module and is used for accessing electrical equipment of which electricity utilization information is to be acquired; the load interface is connected with a power supply through an electric wire, the signal conditioning circuit module is electrically connected with the CPU, and the CPU is electrically connected with the sampling module and used for conditioning signals; the sampling module is electrically connected with the SD card storage module and the load interface, and is used for collecting power consumption data of the load interface and sending the power consumption data to the SD card storage module for module storage; and the CPU is also electrically connected with a wireless network card module, is connected with an upper computer through the wireless network card module, and sends the power utilization data of the load interface collected by the sampling module to the upper computer. According to the portable load data acquisition equipment, the connection with the upper computer is realized through the wireless network card, the device is controlled by the upper computer to perform data acquisition and acquisition, and the acquisition information stored in the SD card can also be acquired, so that the portable load data acquisition equipment is very convenient and portable, and manual field operation is not needed.

Description

technical field [0001] The invention belongs to the technical field of measurement and instruments, and more specifically relates to a portable load data acquisition system and method. Background technique [0002] Non-intrusive Load Monitoring (NILM) is one of the important methods for residential electricity load monitoring. NILM technology calculates electrical parameters such as active power, reactive power, harmonics, and distortion by collecting the voltage and current signals of household entry ports, and then according to the operating characteristics of household appliances, applies matching algorithms to identify electrical appliances online to realize electrical appliances. Real-time monitoring of start-stop time and operating power, so as to obtain information such as energy consumption levels and usage patterns of major household appliances. Compared with the traditional home-based load monitoring method, NILM does not need to install shunt sensors in the home,...

Problems solved by technology

[0003] In the prior art, the collection of load data requires manual operation and extraction after data collection. It does not have the function of wireless transmission of information, which is very inconvenient. Especially when collecting load data from home users, operators need to come to the door one by one Data acquisition, low work efficiency
