The invention provides a management device and method for a wireless sensor network. The management device comprises an energy input interface, an energy output interface and an energy converter, wherein the energy input interface is used for collecting energy of different external energy sources through the wireless sensor network; the energy converter is used for performing electric energy conversion on the collected energy according to the electric energy demand of a sensor adapting to the management device, and outputting the electric energy to the sensor through the energy output interface. According to the technical scheme, mixed input of multiple different energy sources can be accepted, the energy storage function is realized, meanwhile, input and output electric energy related information can be transmitted to the background through GPRS, and control information of the background can be accepted.

Description

technical field [0001] The invention relates to a management device, in particular to a management device and method for a wireless sensor network. Background technique [0002] At present, the power supply method of the traditional chemical battery cannot fully meet the development needs of the wireless sensor network. With the optimal design of wireless sensor networks, the number of nodes is increasing, and the defects of battery power supply are becoming more and more obvious. In harsh environments or other places where humans cannot reach, battery replacement becomes very difficult or even difficult to achieve. The energy supply system has become a key technology that needs to be dealt with in the development of modern wireless sensor networks, and it is also one of the bottlenecks of current wireless sensor networks. [0003] The idea of ​​new energy supply technology has attracted widespread attention, and it can fundamentally relieve the energy supply constraints of...

Problems solved by technology

[0004] However, different types of energy harvesting technologies such as solar power supply, wind energy power supply, temperature difference thermal energy power supply, vibration mechanical energy power supply, electric field and magnetic field energy power supply, as well as inductive wireless energy supply technology, radio frequency wireless energy supply technology, magnetic resonance wireless energy supply technology, etc. Wireless power supply technologies such as laser wireless power supply technology and laser wireless power supply technology can provide different voltages and powers of electric energy; power supply technologies with lower power supply capabilities can only provide electric energy with a voltage as low as a few volts and a power as low as a few watts. The power supply technology with strong power supply capacity can provide tens of volts of voltage and tens of watts of power; and the power supply voltage and power required by different types of sensors are also different, which will lead to the inability to adapt to different sensors. As a result of voltage and power access, it is impossible to supply power to sensors with different requirements for power supply voltage and power. At the same time, when the power supply technology supplies more energy, it is also impossible to store excess electric energy.
