adversely is that at these solutions a direct intervention in the mobile phone is necessary. Furthermore the circuits are not special because the phone number of the caller not evaluated directly. Through short messages - SMS - is one accidental activation possible.

It Mobile phones are known that are not able to work independently Electricity for to supply an accumulator charge. You charge the battery only once, provided the charger not removed again and reconnected.

One Another problem is the unregulated Trickle charging mode. In this Mode, the battery is charged with a small current. Trickle shop closes usually on the normal charging process and lasts up to two Hours. In this case, that must Mobile phone with the charger stay connected. The resulting increased power is problematic if the device to be supplied by a battery.

It Therefore, the task is to provide a device for remote control to create mobile phones that allow easy and safe use of a mobile phone Mobile phones enabled.

These The object is solved by the features of claim 1 or 2 or 3.

The advantages achieved by the invention are in particular that a response from the mobile phone is possible without incurring fees, because the module is refused a connection. Depending on the state of the output (on / off), this happens after the first or third ring. Using the dial tone you can determine when and if was switched. In response to calls, data may also be transmitted via an output unit ( 14 . 15 . 16 ). This can be different data depending on the number of rings.

One Another advantage is that the module over to configure the phone book of the mobile phone.

The Communication unit may include a filter circuit. hereby Is it possible, disturbing influences, z. As a magnetic radiation to prevent.

The Communication unit can be switched off. This can be done reduce the power consumption of many mobile phones. The shutdown can by putting in the high-impedance state or at 0 volt level happen.

The Charging unit can be designed as a step-down converter, the additional with two resistors and a capacitor (C1) is connected. This makes it possible to Charging current for to control the phone from the remote control module.

The Task can also be solved by the features of claim 15. The communication unit and the output unit can be software-based become. Since the telephone with each dial tone a message to the Controller unit sends, this is capable of the number of Recognize dial tone.

The Task can also be solved by the features of claim 16. Again, you can the charging unit and the output unit are designed to be software-supported become. This makes it possible the charge current for to control the phone from the controller unit.

Of course it is possible, the solution characteristics the claims Combine 15 and 16 and to increase the benefits achieved hereby.

The Task can also be solved by the features of claim 22. The mobile phone can also be supplied with a fixed voltage, so that Phone can also be operated without a battery. The advantage lies in that one Operation possible even under conditions which are not compatible with those of a rechargeable battery. To the operating conditions of a battery can its capacity, Internal resistance, voltage, age or even temperature belong.

Should the mobile phone go out, it can be switched on again by the controller become. (Claims 25 and 26). After switching, the control unit transmits the PIN number to the mobile phone. If no PIN has been set this step is skipped. This can be ruled out that the phone is due to lack of battery charge is gone, the battery is previously charged for about 20 minutes.

The Controller unit may be a microprocessor. It can be 20 PINS and 2 kilobytes of program memory. This is her case of all efficiency small and inexpensive.

The Controller unit, the communication unit, the charging unit, the Output unit, the control unit, the power supply unit as well as the connections can be arranged together on a circuit board.

Of course it is also the use of an integrated circuit possible.

The Circuit board can be arranged in a housing.

On the housing the button and the light emitting diode can be arranged.

One embodiment The invention is illustrated in the drawing and is in the following described in more detail. In a schematic representation:

2 a block diagram of an electronics for a remote control module according to 1 and

3 a charging unit of electronics for a remote control module according to 2 ,

A remote control module for phones is in 1 shown. From a housing 4 is a circuit board 1 enclosed with electronics for the remote control module. On the case 4 are a button 2 and a light emitting diode 3 arranged. Out the housing 4 go two leads that go to a connection for mobile phones 5 and to a connection for supply parameters 6 to lead. The connection 5 can be designed as a connector to which a mobile phone 7 , also known as a mobile phone, is connected. At the connection 6 All other connections can be tapped. Also connection 6 can be designed as a connector.

The housing 4 can also be part of a mobile phone case. Here are the circuit board 1 etc. integrated into the overall housing.

The circuit board 1 with the electronics is in 2 shown. The heart of the electronics is a controller unit 11 , It is relatively small and has at least 20 pins and 2 kilobytes of program memory in the selected version.

The controller unit 11 is both about a communication unit 12 as well as a charging unit 13 with the connection for mobile phones 5 connected.

The communication unit 12 has a small filter, the disturbing influences such. B. electromagnetic radiation prevented. The filter connects the controller unit 11 with the mobile phone 7

The interconnection of controller unit 11 and charging unit 13 is in detail in 3 shown. The charging unit is realized here by a step-down converter.

An output A1 of an internal compressor 11.1 the controller unit 11 is connected to the step-down converter as follows:
A capacitor C2 of the converter is connected to its switching transistor T3, which is connected to operating voltage U and via its diode D1 to ground GND. The operating voltage U is 12 V. At the internal Comperator 11.1 it is a component IC1A.

Between the capacity C2 and the switching transistor T3, a resistor R9 is arranged.

Between the switching transistor T3 (FDH636PSMD) and the diode D1 is its Coil L1 is arranged, which is connected to a controller output AS. Between the coil L1 and the controller output AS, a second capacitor C1 is arranged, the at Ground (GND).

At an input E3 of the converter IC1A are two resistors R1, R2 connected as a gamma quadrupole such that the one resistor R2 between the input E3 and the controller output AS and the other resistor R1 between resistor R2 and input E3 and ground GND).

On an input E2 of the Comperator 11.1 is a pulse width signal PWM of the controller unit 11 guided.

The Special of this arrangement is that the typical components (Coil, diode, capacitor, switching transistor) through the capacitor C1 and two resistors R1 and R2 added become.

• – über eine Spannungsversorgungseinheit 16 mit einem Ausgang für Spannungsversorgung 6.1,
• – über eine Bedinelementeeinheit 15 mit einem Ausgang für Taster & LED 6.2 und
• – über eine Ausgangseinheit 14 mit einem Ausgang für Ausgang 6.3 des Anschlusses 6 verbunden.

The controller 11 is also

• - via a power supply unit 16 with an output for power supply 6.1 .
• - via a Bedinelementeeinheit 15 with an output for button & LED 6.2 and
• - via an output unit 14 with an output for output 6.3 of the connection 6 connected.

The output unit 14 is realized with a FET (field effect transistor) stage. In the active state is operating voltage U 12 V minus 0.5 V, in the inactive state, it is high impedance. The output unit 14 leads to a connection for output 6.4 of the connection 6 and has an internal resistance of 0.35 ohms. The exit unit 14 is protected against short circuit, reverse polarity and overvoltage. The output unit is controlled 14 through the controller unit 11 ,

Of the advantage over conventional relay circuits is an extreme longevity and the small footprint of the necessary components.

The control unit 15 allows a connection for appropriate operating and display elements. The internal controls are as mentioned above on the top of the case 4 attached buttons 2 and the light emitting diode 3 consist.

The button 2 Usually serves to local, not over the phone 7 remotely switching on and off the output 6 , A short press is enough. The designed as LED light emitting diode 3 indicates the state of the output. The diode is lit. 3 , is the exit 6 activated.

Both a button and a light emitting diode can be connected externally. The internal Controls remain in place. Both connections are in connection 6.3 secured against short circuit and reverse polarity. The connection for the LED is designed so that a current of 20 mA is automatically set. Vorwiderstände are not necessary. It is also possible to connect several light-emitting diodes in series until a forward voltage which is 3 V below the operating voltage U is reached. This makes it possible to connect LEDs in different colors. The external connections allow the remote control module to be integrated into the dashboard of a car. For this purpose, only a matching illuminated pushbutton is necessary, which is anyway standard equipment in vehicles from about 2003.

The power supply unit 16 has a fixed voltage regulator. It also includes measures to support the electromagnetic compatibility as well as polarity reversal and overvoltage protection.

A configuration of the remote control module is done as follows:
In order to achieve the greatest possible flexibility, it is necessary that some parameters are adjustable. These parameters primarily include phone numbers that you want to work with. Each parameter gets in the phone book of the mobile phone 7 on the SIM card a defined position. From this position he is interrogated. To check whether it is indeed a parameter and not some telephone number, the name is preceded by an "*" so that the corresponding parameters in the right place in the phone book of the mobile phone 7 be held by pressing the button for 30 seconds 2 the corresponding entries are created on the SIM card.

The following Parameters are set:

numbers:

Up to five different numbers can be entered. These numbers will be at startup of the controller unit 11 from the mobile phone 7 read into the RAM memory. A random access memory (RAM) is a random-access or random-access memory in which the memory locations can be addressed directly. If through the controlle unit 11 If a call is detected, the number transmitted by the caller is compared with the number stored in RAM memory.

In addition to the number can also be determined whether this number is the output 6 activate or notify in case of alarm.

If there is an "R" in the name of the number, this can be the output 6 turn. If it is "A", it will be notified in case of an alarm and a combination of both letters is possible.
* RA +491791234345

Recharge Level:

These parameters indicate from which state of charge accumulator of the mobile phone 7 the loading unit 13 should be activated. In particular, Siemens mobile phones have the property not to use independently from a charging current source. Therefore, the voltage must be turned on or off as needed. Since aged batteries are no longer able to reach the full capacity and their internal resistance increases, it is necessary to make the charging threshold adjustable. Old batteries are then charged at 60% residual charge, new at 20%.

The information about the remaining charge is given to the controller unit 11 from the mobile phone 7 ,

The Charge threshold is determined so that it is in steps between 0% and 100% changed can be.

Relay Reset Time:

Here you can specify how many seconds the connection makes for the output 6.3 should be disabled. Provided he was previously over the button 2 or switched on by call. This allows two functions to be realized:
On the one hand it becomes possible to give a pulse with a call. This pulse has a minimum duration of 1 second.

To the others can turn on a device automatically after a certain Time to be switched off. So z. B. in motor vehicle parking heaters An operation of more than 20 minutes does not make much sense.

The Time is between 1 second and 65535 in one-second increments Seconds adjustable. The setting 0 causes this Option is disabled.

HangUpDelay:

After the mobile phone 7 has detected a call, the time set here is waited until it is hung up. The remote control module receives a message each time a dial tone is initiated. After one to three dial tone should be hung up. This delay now causes the user at the other end of the line to hear the dial tone until the end. It was observed that there are other network-dependent delays. These are also compensated. Depending on the user provider so varies the attitude a little.

The Adjustment is made in tenths of seconds. Other settings lengths, eg. B. fifteenth, tenteenths and the like. Seconds to higher times are possible.

Alarm Reset Time:

If an alarm was triggered by an alarm system, this is indicated by the LED flashing 3 signaled. The or several owners of the remote control module are called in turn for 20 seconds and that until the first refuses the call or each participant 5 was called. Thereafter, a new call can not be started until the alarm is actuated by pressing the button. This is useful insofar, if z. B. crawls a spider on a light barrier and triggers a false alarm.

In some cases it is impossible, to acknowledge the alarm locally, eg. B. at a holiday home. In In this case, the option AlarmResetTime ensures that this automatically after the Time set here happens.

The Time is between 1 second and 65535 in one-second increments Seconds adjustable. The setting 0 causes this Option is disabled.

PIN CODE:

If the mobile phone has been switched on by the controller, this must tell the phone the PIN number. The pin number is therefore also deposited in the phone book.

AlarmDalay:

In some installations, it is inevitable that the person entering an alarm-protected system triggers the alarm himself. An example of this is a motion detector mounted inside a room. When the mobile phone 7 in the same room, the motion detector is activated before it can be switched off. This option delays the forwarding to the mobile phone 7 for the set time. Will the button within the time 2 pressed, the alarm and thus the notification is aborted.

AlarminhibitTime:

As already mentioned above, it can not be prevented in some cases that the alarm is triggered when entering and leaving the house itself. The case entering the house has already been explained. This option also helps when leaving the house. After a push on the button 2 can not be alarmed for a moment. The length of the moment can be adjusted.

The button 2 With this setting, it is no longer possible to switch the output locally 6.3 to be used.

The Time is between 1 second and 65535 in one-second increments Seconds adjustable. The setting 0 causes this Option is disabled.

AlarmeIdleLevel:

The remote control module is via the phone book of the mobile phone 7 configurable. Not only are the telephone numbers that are required for switching and alarming adjustable, but also other parameters. So can the time for the automatic shutdown, the charge threshold for the accumulator and the phone numbers in the mobile phone 7 be stored so that there is always an overview of the stored data. By the name of the number, the remote control module also recognizes whether it should be used for incoming calls (for switching) or for outgoing calls (for alerting). At each start, these values are transferred to the remote control module. DIP switches or similar are no longer needed.

Communication with the mobile phone 7 is made on call as follows:
If the mobile phone 7 the controller unit 11 notifies that a call comes in, determines the controller unit 11 the number and compare it with the numbers stored in the memory. If a match is found, then the output can 6 be activated in total or a message via the serial interface of the output unit ( 14 . 15 . 16 ).

Secondary condition here is whether this number is authorized for switching or not. The mobile phone 7 sends a message to the controller unit with each dial tone 11 so that it is able to recognize the number of dial tone. When the output 6 is to be switched on, the controller unit waits 11 a dial tone before answering the mobile phone 7 tells you to hang up.

Communication with the mobile phone 7 is made in alarm as follows:
When the output 6.2 (Alarm input) is activated, tells the controller unit 11 the mobile phone 11 over the exit 5 with that it chooses the numbers of the owners.

It all numbers that are marked as alarm numbers, in turn for 20 seconds each with a break of 10 seconds in between. Of the The process is repeated until either the first person called reject the call or call each number three times or the alarm automatically back was set.

The numbers are in memory and will be sent to the mobile phone 7 transfer. They were originally read in with the configuration.

The battery management is done as follows:
As already mentioned, some mobile phones are not able to self-powered with power for the battery charge. You charge your accumulator only once, unless the charger is removed again and reconnected.

One Another problem is, as already mentioned, the unregulated Trickle Charging mode.

For both reasons, it is deduced to switch off the charging current after completion of the charging process and to switch it on again for later charging. This control is taken over by the controller unit 11 as follows (see in particular 3 ):
The controller unit 11 Generates a square wave PWM with a duty cycle of 50%. This is very accommodating to most controllers because the possible frequency of the square wave PWM is greatest at 50%. (see. 3 - 1 )

This signal is applied to the internal comparator 11.1 the controller unit 11 given. The internal comparator 11.1 is connected as an inverter. It should be noted that the delay that each flank through the comparator 11.1 learns, is dependent on the applied differential voltage.

The differential voltage at the inputs E2, E3 consists of the square wave signal PWM and the feedback output voltage (see. 3 - 4 ) at the controller output AS. This is in the steady state near the Rechteckamlplitude.

If the square wave signal is "high" then the difference voltage is relatively low, the edge delay time increases the closer this voltage is to the reference, and if the square wave signal PWM is "low" the voltage is relatively high. The comparator 11.1 switches quickly. The result is a feedback that the output signal of the comparator 11.1 so affected that the duty cycle at the output A1 decreases when the voltage rises (see. 3 - 2 ). This can even lead to the omission of whole pulses. It is essential, however, that a very simple and, above all, a very effective regulation of the output voltage takes place. However, a prerequisite is that the delay time of the comparator is similar to the period of the square wave signal PWM.

About the capacitor C2 is the rectangle according to 3 - 2 directly to the transistor T3 given (see. 3 - 3 ). The transistor T3 has been selected so that its threshold voltage is less than half the supply voltage of the controller unit 11 is. As a result, it switches with exactly the same frequency to the same duty cycle of the square wave signal PWM. The gate charge of the transistor T3 can be reloaded very quickly. Other circuits use driver stages at this point, which usually work with pull-up resistors. These usually change the duty cycle due to their delay times.

Another advantage of the loading unit 13 according to 3 consists in addition to the already described therein that no voltage, regardless of the state of the controller unit 11 , is generated when no square wave PWM is applied. A failure or crash of the controller unit 11 Switches off the charging current.

On and off the output 6 via the button 2 , A single press is enough.

The state of the output 6 is through the light emitting diode 3 displayed.

A light of the LED 3 shows an active output 6 at.

When the alarm is triggered, the LED flashes 3 permanently. If the button is now pressed, the alarm is reset. The light-emitting diode 3 stop flashing and the button 2 can switch back to the output 6 be used.

If the button is pressed for more than 30 seconds, the basic configuration will be in the mobile phone 7 stored. This is confirmed by three short flashes.

If the already explained AlarmInhibit is used, then with the button 2 not the exit 6 but the triggering of an alarm for a certain time prevented.
