Wirelessly networked meter-reading and energy-saving controlling system

Abstract

The invention provides a wirelessly networked meter-reading and energy-saving controlling system. ZIGBEE wireless sensor network technology is employed in the system. A small electric energy meter wireless sensor node and a coordinator thereof are designed so that electric energy meters in a certain range can form a wireless network in MESH-type network topology structure and electric energy data of users can be acquired in real time and a database management and control system is designed. Electricity utilization status in a relative building can be monitored and counted and power supply is remotely controlled through software. The power supply of a user can be determined through a password and an ID of an electric energy meter texted in short messages, thereby controlling operation of household appliances and achieving an energy-saving purpose. The system has advantages of a wireless and networked structure, system remote control, mobile phone remote control and data real-time acquisition. The system is easy to install, is convenient to use, is low in cost of investment and maintenance and is low in operation cost.

Description

technical field [0001] The invention relates to the field of machinery and control, in particular to a wireless networked meter reading and energy-saving control system. Background technique [0002] In China, meter reading operations are generally recorded by manual meter reading. Our country has put forward the slogan of building a smart grid in recent years, and has invested a lot of money in the construction of smart grids. At present, in terms of centralized meter reading, most of the domestic use is RS485 serial wired transmission, which collects data from meter modules within a certain range, and then transmits it remotely through GPRS / CDMA. At present, there are very few wireless networked meter reading systems that are actually put into commercial operation in China, and most of them realize wireless network establishment through Wi-Net technology, which is costly. [0003] Patent CN 101996481 A discloses a wireless remote meter reading system, including a user ter...
