The damage of machine extends the service life of washing machine.The present invention can in time be found in washing machine machine barrel when washing whether
There are organism, the water storage in a confirmed timely discharge machine barrel that organism is prevented to be drowned in machine barrel.
The present invention, for the information transmission between each module, ensure that information transmission using ZigBee wireless communication networks
Safely, effectively with it is convenient.
ZigBee is a kind of highly reliable wireless data sending network, is similar to CDMA and GSM network.ZigBee digital transmission module classes
It is similar to mobile network base station.Communication distance supports infinite expanding from 75m to hundreds of meters, several kilometers of standard.ZigBee is
One by can the wireless data sending network platform forming of more to 65000 wireless data transmission modules, within the scope of whole network, often
Can be in communication with each other between one ZigBee-network digital transmission module, the distance between each network node can from the 75m of standard without
Limit extension.
The characteristics of ZigBee is short distance, low complex degree, self-organizing, low-power consumption, low data rate.It is mainly suitable for for certainly
Dynamic control and remote control field, can be embedded in various equipment.In brief, ZigBee is exactly a kind of cheap, low-power consumption
Near radio networking mechanics of communication.ZigBee is a kind of wireless network protocol of low speed short-distance transmission.Zigbee protocol from
Under to it is upper be respectively physical layer (PHY), MAC layer (MAC), transport layer (TL), network layer (NWK), application layer
(APL) etc..Wherein physical layer and MAC layer follow the regulation of IEEE 802.15.4 standards.ZigBee-network is main
Feature be low-power consumption, low cost, low rate, support great deal of nodes, support multiple network topology, low complex degree, quickly, reliably,
Safety.Equipment in ZigBee-network can be divided into coordinator (Coordinator), aggregation node (Router), sensor node
(EndDevice) Three roles such as.
The present invention converts solar energy into electric energy, to charge the battery, environmentally protective.
Solar energy is released huge nuclear energy by the generation hydrogen helium fusion of solar interior hydrogen atom and is generated, from the sun
Radiation energy.The overwhelming majority of necessary for human energy is all directly or indirectly from the sun.It is non-to be radiated at tellurian solar energy
Chang Ju great is radiated at tellurian solar energy in about 40 minutes, it is sufficient to for the consumption of 1 year energy of global human.It can
To say, solar energy is real inexhaustible, the nexhaustible energy.And solar power generation absolute cleanliness, do not generate public affairs
Evil.So solar power generation is known as being the ideal energy.
Electric power is obtained from solar energy, light-to-current inversion need to be carried out by solar cell to realize.It sends out with other previous power supplys
Electric principle is entirely different, has the characteristics that：1. without exhausted dangerous；2. absolute cleanliness（It is nuisanceless）；3. not by resource distribution
The limitation in domain；4. can nearby generate electricity at electricity consumption；5. energy quality is high；6. user is acceptant from emotion；7. obtaining energy
The time that source is spent is short.Shortcoming is：1. the energy profile density irradiated is small, i.e., to occupy huge area；2. the energy obtained
The source same four seasons, round the clock and rain or shine etc. meteorological conditions are related.But generally speaking, one flaw cannot mar the jade, and as new energy, solar energy has pole
Big advantage, therefore paid attention to by countries in the world.
Solar power generation has two major classes type：One kind is solar power generation（Also known as solar energy generates electricity）, another kind of is the sun
Heat power generation（Also known as solar energy thermal-power-generating）.
Solar energy power generation is a kind of generation mode that solar energy is translates directly into electric energy.It includes photovoltaic generation, light
Chemically generation, light induction power generation and photo-biological four kinds of forms of power generation, have electrochemistry photovoltaic cell, photoelectrolysis in photochemistry power generation
Battery and photocatalytic cell.
Solar energy thermal-power-generating is first to convert solar energy into thermal energy, then thermal energy is converted to electric energy, and there are two types of conversion sides for it
Formula.One is solar thermal energy is directly translated into electric energy, such as semiconductor or the thermo-electric generation of metal material, the heat in vacuum device
Electronics and the power generation of thermoelectricity ion, alkali metal thermo-electric conversion and magnetohydrodynamic generator etc..Another way is to pass through solar thermal energy
Heat engine（Such as steam turbine）Electrical power generators are driven, similar with conventional thermodynamic power generation, only its thermal energy is not from fuel, and
It is to come from solar energy.
The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this
The principle of invention, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these changes
Change and improvement all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appended claims and its
Equivalent thereof.
