6 cl, 2 dwg

The present invention relates to a radio control electric devices.

In particular, this invention relates to control electrical devices such as, for example, gates, doors, front doors and fences in General.

Device control is usually performed as a self-learning, i.e. such that can be programmed using another control device of the same type, i.e. the code can be saved in him, received from the control device of the same type that is properly configured to perform such tasks.

Automatic gates or barriers for entry into private spaces, such as, for example, roll-up doors, or closed areas, such as public Parking lots in the condominium, are usually managed by users through the remote control, which sends a radar pulse to the electronic control unit, which opens the barrier.

In addition, mainly in the case of remote radio after receiving the signal to open the gate then there is a subsequent closure by submitting the user of the second signal or it happens automatically after a predetermined period of time.

Sometimes for entry on private property, e.g. in a garage in W the scrap house, need radio broadcast several signals that differ from each other (for example, the first signal is applied to open the gate to the site of the condominium, and the second signal to open the lifting door).

In addition, each area (for example, the territory of the condominium shall be fitted with a unique key that is different from a key to another site.

To overcome such disadvantages, a device control, adapted to store multiple codes that are different from each other, and unambiguous programmable key.

Aspect the present invention relates to a control device for an electric device, comprising a housing with buttons, which houses the electronic circuit includes an electronic receiver to send an unambiguous code specified electric devices, microprocessor, in which the signals generated by pressing the following buttons and which controls the specified transmitter and receiver, and determines the specified pass-through identifier, the digital manipulator consisting of a set of switches with two or more clauses, which feeds the generated signal in the specified microprocessor, with the specified Combinator is made with the possibility of installing an unambiguous key is, forming a device group control of the same type, which is stored in the microprocessor and subsequently deleted digital Combinator so that he could not be seen when opening the specified enclosure and access to the Configurator after completion of the saving process.

Features and benefits of the transmitter in accordance with the present invention will become clearer from the following illustrative description, not limiting the present invention, with reference to the accompanying schematic drawing, on which:

- Figure 1 is a perspective view of two transmitters, made in accordance with the present invention;

- Figure 2 is a block diagram of the electronic circuit in the transmitter, in accordance with the present invention.

According to the above drawings, the control device in accordance with the present invention includes a housing, for example housing 2 in the form of a box, into which you have inserted electronic card with an Autonomous power source, for example, by a battery, the control of which is possible with many of the 3 buttons located on the specified case.

The block diagram of such an electronic circuit is shown schematically in figure 2, which shows the microprocessor 4 of the controller that contains the encoder 41 and de is tiraumea 42 of the device.

In the controller, the signals from the buttons 3 and the signal generated by the digital schemer (also called DIP-switch) 43, consisting of a set of switches, enclosed in a separate casing and provided with contacts arranged in two rows on the normalized distance. Preferably use the dip switches, but the alternative positions may be more than two. By managing each of these switches it is possible to generate a clear key, which can be configured and modified depending on the intended use of the device radio. This key is first installed on the specified schemer, is stored in the control device and removed so that he could not be seen when opening the case and access the Configurator after completion of the saving process.

The key defines a group of control devices belonging to the same group (for example, the group supplied the same installer or distributor), which establishes and defines the key.

In addition, the electronic Board includes a receiver 51 and the transmitter 52, connected to the specified controller 4, and tools 6 power, which serves the necessary power supply to all components of the electronic Board. Also on Board is nedosmotreli appropriate means 53 amplification and filtering of signals, received the specified receiver, and signals which are to be submitted on the specified transmitter.

Additionally, the control device is equipped with at least one special signal led is controlled by the microprocessor.

At the same time, the control device can be provided with codes that differ from each other.

The transmitter transmits an alternating type of code, subsequently appropriately decoded by the microprocessor in such a way as to hide the code, for example, from the analysis performed by the oscilloscope.

The microprocessor or the Combinator device control allows using digital schemer to program a key that can be removed from the Configurator. In particular, in accordance with the present invention are possible for storing a key can be done using the following steps:

a) to install the necessary key Combinator;

b) Pressing one or more buttons of the remote control within a predetermined period of time;

C) the Possible release of one or more of these buttons until the alarm led will not emit a predetermined sequence of light pulses;

g) removing the key from the digital schemer by setting a predetermined base is a combination (for example, all "off" ("OFF") or all "on" ("ON")).

At the end of this procedure, the key is saved and becomes invisible to the user who does not have ownership of the given key.

Code, processed and stored in the microprocessor, may be of different lengths (for example, 12 or 24 bits).

This code is mainly modulated in accordance with the procedure of modulation, such as amplitude shift keying OOK (On-Off-Keying) or amplitude modulation AM.

As discussed previously, the control device in accordance with the present invention is also provided with a receiver, and thus, the self-learning procedure can also be performed with it from another device, radio control, with the same code. Otherwise, it can be saved other code that does not belong to the same device group control, defined by the key.

In particular, in accordance with the present invention the procedure of learning to code, not belonging to the group with the same key, which is stored in the control device, can be performed in accordance with the following steps:

- Set the current stored key in the transmitting device control;

- Switching the device control, the host code, in the learning mode;

- Select the button to be bound p is inimage device control;

- Clicking on the sending unit, radio control buttons relating to the code intended for transmission to the receiving radio.

The signal is detected on the receiving device control via led (for example, it flashes three times), which indicates that preservation has definitely occurred.

This procedure enters in the receiving device, radio, and the new key is the same as the key transmitting device control, and the new code button (associated with the selected button).

If the set key is already present in the receiving device, radio control, this key is overwritten.

In addition, to prevent the simultaneous existence of the last set key and key previously installed there is no need to move the switches schemer in the base sequence.

To enable the use of radio in accordance with the present invention with a simple code systems Keyless transmitter can transmit various modulation for different buttons. Essentially when installing the key all the buttons have their own code. However, it is possible to associate with the button code received from the device control, without a key. This can be accomplished by re the ode device control, which is the subject of the present invention, in the learning mode and pressing the preset button to save the code received from the external device control, and transmission of the code that you want to save. Thus, the selected key is associated with a new code.
