The The invention relates to a communication module for mailboxes, mailboxes, intercoms or external stations, such as steles, wirelessly and self-sufficient about a solar module is operated. Under mailbox is according to the invention also only a permanently mounted, for example, in a pillar, To understand entry or pass.

Various door communication systems are already known from the prior art, the system either being wired or the data transmission being ensured via an analog radio link. Furthermore, systems are known in which also a solar cell comes as an energy source in question. So is in the DE 43 04 999 A1 describes a mailbox with a signaling device that can be powered, inter alia, by a solar cell with electrical energy. This is also described in G 94 17 258.7. There, the power supply is represented by means of a solar cell for LCD displays. The use of a solar cell as an energy source for a scanner in mailboxes is also in the DE 102 20 915 A1 mentioned. The integration of a solar cell as an energy source in a door intercom was in the DE 198 11 064 C1 mentioned. However, the technical involvement was not explained.

The Integration of a location-independent power supply by at least one solar cell in conjunction with an accumulator and the link a well-known from the prior art door phone with a likewise known from the prior art separate transmission module letterbox systems However, including lighting in the past proved as difficult. This is what the individual electrical components demand the provision different electrical voltages. In addition, the performance decreases the individual electrical components very different.

The The object of the invention is a mailbox with electrical Components, such as lighting, at least one bell button and to provide an intercom without a wired Power supply works, with a lasting and functional safety granting the electrical components Energy supply via ensure at least one solar cell. It is to prevent that peak loads lead to system crashes. additional is a communication module with high voice quality for a variety of participants.

The Tasks are performed by a communication module. Claim 1 solved. preferred and advantageous embodiments are specified in the subclaims.

hereafter If the communication module consists of at least one DECT transmitter, at least one speech module, an energy source with unsteady energy production, the at least one solar cell and at least one accumulator with Charge regulator or at least one high capacitive capacitor, wherein the communication module at least one regulated electronic Voltage transformer and / or at least one adjustable voltage regulator owns and the one or more regulated electronic voltage transformers and / or adjustable voltage regulator a variable output voltage the power source in at least two predefined output voltages and / or currents for the differentiated supply of the transmitter and other customers convert or model.

The targeted modeling of the variable output voltage in at least two predefined output voltages from customers, such as the sender and for example in a further embodiment of the invention provided lighting unit allow a balanced energy management. The voltages and possibly also the current are tailored specifically to different customers and can the need, for example an additional door opener or lighting devices, be adjusted.

In Further embodiment of the invention, the lighting unit a switching threshold and a twilight sensor on.

Further it offers itself in a further embodiment of the invention for further Reducing the voltage next to the transducer (s), a waste diode use. This is necessary when manufacturing a transducer for one certain customers with certain voltage requirements too costly is.

According to the invention in a variant, the transducers also be coupled to each other in such a way that again reduces an output voltage of the first converter to meet the requirements of a customer, so the transmitter module adapt.

This can also be done by a coupling with the adjustable voltage regulator, so that in the embodiment of the invention, a also manually modifiable voltage modulation is ensured. Thus, with the optional connection of another customer, the energy requirement can be optimally adjusted without exchanging components to have to. The latter would prove to be very costly and thus uneconomical in relatively simple systems, such as mailboxes.

Of the regulated electronic converter is advantageously a DC / DC converter, wherein in a preferred embodiment of the invention, a galvanic separate down-converter is used. Important characteristics of the converter or the Transducers are a wide input range, exemplified by 9-16 V, a high level smoothing the output voltage and a high temperature insensitivity. Dependent on the season is the converter at temperatures of -25 ° C and up + 80 ° C full functioning. The output range of the transducer (s) is differentiated and preferably exactly adapted to the customers.

The Energy source consists of at least one solar cell, preferably a solar module and at least one accumulator with charge controller or at least one high capacitive capacitor. As a high capacity Capacitor come one or more Goldcap Capacitors (Goldcap Register) in question. As an alternative to the accumulator Goldcap capacitors used, the charge controller can be omitted.

Of the Sender is linked to the voice module, so the voice module also over the transmitter is supplied with electrical energy. As transmitter comes in An embodiment of the invention, a commercially available DECT transmission module or a comparable module is used. The transmission module has become as proved particularly advantageous. As a voice module comes a standard wired Intercom station into consideration.

By the invention provides a communication module, that without wired energy supply and without wired transmission the communication data with high voice quality - because of the DECT standard - reliable works, even if multiple components, so the lighting unit and the voice module are operated simultaneously. The high functional safety is described by the invention Energy management through the use of transducers with targeted voltage modeling ensured. The guaranteed also the flexibility in use with different customers.

Of the Use of the transmitter module in conjunction with the voice module also allows The integration of up to 12 participants in a telephone system. The Voltage modulation is particularly important here, since the illustrated variability of the speech module in terms of the number of participants of a differentiated Energy management needs. Also, the use of different Elements of a speech module, so components that allow humans To transform information into signals for electronic processing, so sensors of any kind, for example, pressure-sensitive sensors, optical or acoustic sensors different requirements due to a customized modulation the electrical energy, in particular a voltage modulation, granted can be.

The Invention will now be described with reference to an embodiment with reference closer to the figures explained.
