Definitions
- the subject matter relates to an irrigation control device, in particular for use in a home automation system.
- Home automation systems also known as smart home systems, control not only lights, blinds, and heaters, but also various other domestic home appliances.
- radio-based smart home systems however, the energy requirements of actuators and sensors are always challenging. Because users do not always want to replace batteries on their devices (from comfort and convenience)
- the energy supply is of particular importance.
- irrigation control preferably arranged outside the home appliances, such as irrigation control, the energy supply is of particular importance.
- Irrigation computers are often fully self-powered.
- the object is the object of a

- Energy storage must thus provide electrical energy only for these two actions even with longer irrigation periods or longer periods between two irrigation cycles.
- the energy storage should also provide sufficient energy for operating a control device, which is in particular connected to a home automation system. This control device is used to receive and send signals to a home automation center and must be permanently supplied with electrical power. The power consumption of such
- control devices can be very small.
- an energy requirement of a control device can be a few milliwatt seconds per day, in particular between 10 and 15 milliwatt seconds per day.
- the physical energy store is thus charged by the turbomachine and discharged both to operate the obturator and preferably a control device.
- batteries are dispensed with in the irrigation control device, but a rechargeable energy store, in particular a capacitor or a rechargeable battery, is used.
- a so-called Goldcap capacitor is used here to ensure maximum life and temperature resistance.
- Microturbine can be driven, the energy of the medium flow from the inlet to the outlet, in particular the flow of water from the inlet to the outlet is used with open obturator to recover electrical energy and recharge the energy storage.

- an induction coil is arranged in the region of the transducer. This induction coil may be formed as a stator winding, and a current is induced therein by the magnetic field generated by the permanent magnet.
- a control unit is provided in the irrigation control device, that the control unit is powered by the energy store and that the control unit is the obturator controls.
- the control unit is preferably energetically self-sufficient by the
- control unit requires at least a permanent power supply, for example, to process an irrigation program. This can be ensured by the energy storage described above.
- the control unit may comprise a microprocessor which can operate in a so-called deep sleep mode and is only woken up at certain times. This greatly reduces the power consumption of the control unit.
- a control pulse is transmitted to the obturator by the control unit.
- This control pulse can cause the opening or closing of the obturator.

- the gate valve may be adjustable by electric motor in addition or alternatively to the electromagnetic adjustability.
- the spring can also act. In an electromotive drive this can, for example, drive a worm gear and thus cause a transverse movement of the gate valve.
- the gate valve may have a tapered end. The taper may be such that, seen from the flow direction, the gate valve tapers in the direction of its end.
- the end is tapered such that the medium flowing on the tapered end causes a force component on the gate valve which moves axially in the direction of the gate valve Direction of movement is directed.
- the flowing medium supports the opening process in which it exerts a force on the gate valve, which is directed against the spring force.

For closing, however, the gap must be closed, flows past the medium at the end of the gate valve and exerts the force acting against the spring force. This closing process is electromagnetically assisted by the electromagnetic force acts in the direction of the spring force on the gate valve.
