Abstract

method for the initialization of radio receivers, at the first of a transmitter selected and called a predetermined group of radio receivers will, after a response the called radio receiver changed the group selection for so long until a particular single radio catcher is identified and at the following this single radio receiver the transmitter ID number is learned.

Description

The The invention relates to a method for initializing radio receivers according to claim 1.

Become Radio transmitters as command devices, e.g. as switches, dimmers, gate controls, roller shutter controls etc. used, is usually assigned a fixed number in the transmitter, which is encoded in operation in all transmitted radio signals.

at During commissioning, this number is taught in at all radio receivers. which should react to the transmitter signal (initialization). For this purpose, it is necessary, the or each recipient (and only these) into a learning mode, e.g. by pressing Keys happens.

One Problem arises, however, if the recipient is not accessible and other receivers continue to be within range of the transmitter. There is then the unwanted Probability that these other recipients the ID number of the sender learn what leads to errors in the operation. Typical example: in become an office building many motorized, radio controlled outdoor shutters installed. Later should Radio transmitter taught to individual shutters or groups become. However, these are no longer accessible and can not be put into learning mode individually.

A previously known option is, all recipients disconnected from the mains, which are not to be taught. Of the Sender then sends special initialization telegrams, which In addition to his ID number, the command to teach them. This is expensive, not always possible and carries the risk from mistakes.

From the DE 29 46 942 A1 It is known to identify elements of a group of radio receivers designed as labels. Furthermore, from the DE 199 32 147 A1 a security container, which assigns an identification code to a radio key during initialization. This is stored in the security case, if no so-called change code is used. With this identification code, the transponder addresses the security container in order to open it.

task The invention thus provides a method for initializing radio receivers provide that conveniently feasible is.

These Task is according to the invention with the solved specified in claim 1 measures.

Thereby, that first predetermined group of radio receivers selected which lies in the transmission range of a radio transmitter, which acknowledges itself and the group is decremented until a particular radio receiver is identified is and then the identity fixed, i. The transmitter ID number can be taught in several Receiver convenient be initialized.

Further Embodiments of the invention are shown in the subclaims.

following the invention with reference to the drawing with reference to a embodiment explained in more detail.

It demonstrate:

1 a basic structure of a transmitter-receiver arrangement,

2 the inventive method in the flow chart.

According to 1 In principle, the following arrangement is provided.

A transmitter S transmits via an antenna 3 from the broadcast stage 1 according to a control by the transmitter control 2 Transmission signals. These are called receive signals via an antenna 4 received by a receiver E1. A receiver stage amplifies and demodulates the received signal into a payload signal and passes this to a receiver control unit 6 to. This evaluates the useful signal and controls accordingly a device to be controlled, such as window blinds, lamp dimmer, etc. on.

In The rule is still at least a second receiver E2, the same in principle is in the transmission range of the transmitter S be present. The following described embodiment However, an initialization method can basically only with a transmitter and a receiver carry out.

With The method described below is a direct assignment of recipients from the transmitter allows without an input in the receiver too need.

For this purpose, a special initialization transmitter S, hereinafter referred to as transmitter S, is necessary, in which is first entered a einzulernende ID number. The input can be done manually, via a wire connection or preferably via radio.

The Transmitting power of the initialization transmitter is such that only receiver near (preferably <10 Meters) whose signals can be evaluated. This can be the number of recipients, which can be initialized to narrow down to this radius.

Of the Initialization transmitter sends a radio telegram in the next step, which puts all receivers in range into an initialization mode added. This mode causes a random, temporary Ident number in the receiver is awarded. The length this number is chosen as that the probability that 2 same numbers to different receiver be awarded, is sufficiently small. Alternatively or additionally Also an ID number can be used, which already in the manufacturing process in memory Recipient deposited non-volatile has been.

The assignment of the sender ID number to exactly one recipient is now achieved by the following procedure:
The initializer sends a command to the action. One action is, for example, to switch on the light, move the shutter briefly, etc.

All Receiver, whose ID number satisfies a particular criterion (e.g., the binary coded ID number) has in the last place a "1") lead this Action off. When the recipient to be initialized responds, the result becomes entered into the initialization transmitter (preferably manually). After that, the next one will be Criterion (e.g., whether the binary coded ID of the receiver in the penultimate place has a "1") .The result is entered again in the initialization transmitter. After a finite number of these steps, with binary coding the maximum number of digits the recipient ID number corresponds, the initialization transmitter knows the ID number of the Receiver and can this (specifically this) specifically teach in the desired transmitter ID number. The entire process is repeated with all receivers to be initialized. The process of querying the various criteria can be automated (for example, according to a fixed or variable time grid).

The Clear Certain ID numbers on a part of the recipients are analogous.

According to 2 The embodiment of an initialization method looks like this.

To a start step ST0 are all in the reception area lying receiver addressed in step ST1. This is as a wake-up too understand. Thereafter, in step ST2, a particular group of recipients selected and selected to identify oneself. This identification can be, for example by short movements, light signals or acoustic signals of the to be controlled equipment respectively. In step ST3, it is determined whether the selected group only one member left. If this is not the case, then the step is over ST3A a change made the group selection. Does the group have only one member left? it becomes an identity mark assigned, which thus both sender side and receiver side known and assignable. Subsequently, it is determined in step ST5 if there are more recipients to identify. If this is the case, then again in Step ST3A a change the group selection. If all recipients are identified, then the process ends in step ST6.
