The road direction that one of development must walk, therefore saving the sense of urgency of the energy makes many companies be devoted to develop solar energy series product
As solar water heater and its control method Subcommittee-to study carefully and produced.With the Bu Duan Jin Walk of technology, performance constantly improve, cost
Under the trend gradually reduced, it must replace the cheap but big complete electrically heated water heater of power consumption and as a kind of heat of popularization
One of water supply source.As the progress of science and technology and the dike of living standard are high, people with solar energy hot water supply system to having respectively
The requirement of formula various kinds, such as to system in the convenience installed, using upper security, reliability and maintenance in the future
Convenience has more requirements.

Heater 5 powers, receives water level and temperature detection signal and water supply.
As above, interconnected more than existing control system of solar energy water heater using wired mode, because controller is from too
It is positive can water heater it is distant, it connects up, installs and safeguarded etc. than more complicated, and poor expandability is short of flexibility；Especially
Be power line wiring distance it is long, it is poor using upper security, easily occur leaking electricity and when controller 10 aircraft bombing situation occurs also
There is generation.
As an improvement, wireless communication mode is a kind of approach, existing use wireless communication mode carries out solar water
Device control principle be：The message that water temperature and level sensor are detected is modulated to radiating circuit, and passes through high frequency radio
Ripple is sent in the controller receiving circuit being normally within doors, and when controller receives related data message and after by processing
Electrical heating, upper water water valve, the switch such as heat tracing heating wire and booster pump is made appropriate to open or close to meet user to hot water institute
The requirement of setting, and these most equipment are all provided in and in solar energy water storage tank or are installed in from solar water container
It is relatively near, but the place from controller farther out, thus in wiring, than more complicated in terms of installing and safeguarding, and be located within doors
Controller receives the reliability of the message detected from water temperature and level sensor because radio wave may pass through several
Wall gets to controller, thus can influence to receive the stability and reliability of these messages, makes controller easily send out
The relevant control message made mistake.
Due to it is general set solar energy water storage tank it is local from controller farther out, therefore part is connected up from controller to electricity
Heater, upper water water valve, heat tracing heating wire and booster pump can be set out of doors, thus affected by environment such as rainwater, humidity
And thunderbolt etc. easily makes wiring damaged, potential safety hazard is produced.
It thus is seen that developing a kind of remote control distance farther out, working stability can save water temperature and level sensor, electricity
Heater, upper water water valve, heat tracing heating wire and booster pump etc. are connected to the connecting line in controller, using upper safer,
The solar water heater remote control system of convenient Function Extension and maintenance etc. in the future is with necessary and far-reaching significance.
