Definitions
- the invention relates to a method of communication between a transmitter of orders and a bidirectional transmitter-receiver for the control of elements ensuring the safety and / or comfort of a building, the communication of control orders from the order transmitter to the order transceiver, or from the transceiver to other elements, by means of frequency-modulated radio signals. It further relates to a command transceiver for implementing this method as well as an installation comprising such a transceiver and a command transmitter.
- An installation comprising order transmitters and order receivers is used, for example, to control motorized devices such as blinds, rolling shutters or even to control lights or alarm systems.
- Each controlled device is associated with a command receiver. However, provision can be made for a command receiver to pilot several devices.
- the transmitters of orders and the receivers of orders communicate at a distance, in particular by using an electromagnetic signal and in particular a radioelectric signal, it is necessary, in the same installation, that the transmitters of orders are paired with the receivers of orders.
- This matching procedure can take several forms. From US Pat. No. 4,750,118, a matching procedure is known which makes it possible to record the respective identifiers of a plurality of command transmitters in a memory located in a command receiver. In operational operation, the order receiver only validates orders received after having noted that they come from an order issuer whose identifier has been previously registered. This solution involves assigning an identifier to each order issuer during its manufacture.
- Another known solution consists in assigning a unique identifier to the order receiver. This identifier is communicated, during a programming operation, to each of the issuers of control orders.
- US Pat. No. 5,148,159 describes a system in which the identifier of a command receiver is communicated to command transmitters by a serial transmission of the asynchronous type.
- a method of communicating a code from a command receiver to a command transmitter is known. This communication is carried out using a low frequency inductive link. Coil and capacitor systems are provided at the command receiver or at a programming system and at each command transmitter to ensure the transmission of the code.
- This low frequency link implies a shorter range than a high frequency link, but it makes it possible to reduce costs compared to a traditional high frequency communication.
- application EP 0 440 974 discloses an installation for communication between transmitters of orders and receivers of bidirectional orders by different frequencies, so as to differentiate the range and the signals transmitted.
- a motorized garage door comprising a command transmitter and a command receiver.
- the transmitter comprises means for activating a modulator making it possible to enter a state in which the transmission of signals is possible.
- a transmitter comprising means for waking up a microprocessor ensuring the generation of signals to be transmitted.
- the object of the present invention is to propose a method of communication and a transceiver of orders providing a solution to the cited problem and improving the communication methods and transceivers of orders known from the prior art.
- the invention provides a two-way communication method between at least one order transceiver and an order transmitter whose manufacturing costs are low.
- the method according to the invention is characterized in that, in a programming mode, the command transceiver activates and successively interrupts the emission of electrical signals normally used for communication in frequency modulation, so as to transmit information towards the transmitter of orders by means of radio signals amplitude modulated.
- the adaptation costs of the receiver enabling it to perform the function of transmitting amplitude-modulated signals are low.
- amplitude modulation communication is implemented in particular during pairing procedures, the limited scope of this mode of communication does not constitute a nuisance for the user and makes it possible to avoid interference with other handling systems or errors.
- the order transceiver made up of frequency modulated radio signals comprises, according to the invention, an antenna connected to:
- It is characterized in that it includes means for activating and inhibiting the transmission means for implementing the communication method defined above.
- the invention also relates to an installation comprising at least one previously defined order transceiver and at least one order transmitter provided with signal transmission means. modulated radio waves and means for receiving amplitude modulated radio signals.
- the communications from the order transmitters to the order transceivers are carried out by frequency modulated signals and the communications from the order transceivers to the order transmitters are carried out by amplitude modulated signals.
- the appended drawing represents, by way of example, a command transmitter and a command transceiver according to the invention.
- FIGS. 1a to 1c are diagrams representing, a transmitter of orders and two transceivers of orders as well as the different modes of communication intervening between them.
- FIG. 2 is a diagram of a command transceiver according to the invention.
- FIG. 3 is a diagram of an order transmitter according to the invention.
- the control installation shown in FIGS. 1a to 1c comprises two command receivers 10, 30 and a command transmitter 20.
- the command receiver 10 has a command transmission function (symmetrical bidirectional communication), of so as to be able to communicate with other elements of the installation.
- the command receiver 10 is a transceiver, it is designated, in the description, by the name of "command receiver".
- the order receiver 10 is capable of receiving control orders from the order transmitter 20 with which it is associated, so as to control comfort and / or security equipment of a building such as a door, a shutter or an alarm system.
- the order receiver 10 can also send orders to the other receiver 30 of the installation to control, for example, other equipment in the building. It can operate in ultra high frequency and bidirectionally.
- the order transmitter 20 transmits orders by means of electromagnetic waves of the radio type at ultra high frequency.
- the order transmitter 20 communicates with the order receiver 10 in an asymmetrical bidirectional manner, that is to say that the signals transmitted and received are not modulated in the same way.
- the command transmitter 20 transmits frequency modulated signals to the command receiver 10 as shown by the arrow 40, however, the command transmitter can only receive amplitude modulated signals.
- the command receiver 10 also communicates asymmetrically bidirectionally with the command transmitter 20. However, it communicates symmetrically bidirectionally with the command transmitter 30 capable of receiving frequency modulated signals.
- the command receiver 10 is capable of transmitting, and the command transmitter of receiving, amplitude modulated signals. This communication is based on an amplitude modulation at low speed of the carrier of the frequency modulated signal transmitted by the receiver 10. It has a range of the order of 50 cm to 1 m, weaker than the range of the signals modulated in frequency.
- the receiver 10, shown in FIG. 2, comprises a module 12 for transmitting and receiving frequency modulated signals.
- This module is connected, on the one hand, to an antenna 11 and, on the other hand, to a logic processing unit 13. It comprises a circuit 121 R for amplifying and filtering the signals received by the antenna 11 then a circuit 122R for demodulation of amplified signals. The output of the demodulation circuit is connected to the logic processing unit.
- the signals picked up by the antenna are converted through this transmission and reception module 12 into an order which can be interpreted by the logic processing unit which controls an item of equipment 14.
- the module 12 for transmitting and receiving frequency modulated signals further comprises a circuit 122E for modulating orders from the logic processing unit and a circuit 121 E for amplifying these modulated signals connected to the antenna.
- command orders can be sent from the order receiver 10 to the order receiver 30.
- the modulation circuit 122E is for example a VCO (voltage Controlled Oscillator), therefore having an oscillation function.
- the circuit 121 E can then be a simple switch for connecting to the antenna or for short-circuiting the antenna.
- the part of the receiver ensuring the signal transmission function has additional elements. It has in particular a module for controlling the transmission means (121 E, 122E) of the transmission and reception module 12.
- This module makes it possible to control the transmission of an amplitude modulated signal which corresponds to an identifier that the receiver 10 for example assigns randomly to the transmitter 20.
- the sending of such a signal is for example controlled by a medium 140 commanding that the command receiver be put into programming mode.
- Programming mode corresponds to a mode in which the receiver transmits information, of the identification code type, to one or more issuers of orders.
- the means 140 for putting into programming mode may for example consist of a push button fitted to the order receiver 10 and being connected to its logic processing unit.
- the amplitude modulated signal is transmitted over a short distance.
- the logic processing unit When the receiver 10 is put in programming mode, the logic processing unit generates on one of its outputs a signal composed for example of a succession of low states and high states corresponding to an identifier to be assigned to the transmitter of orders 20.
- This succession of high and low states causes via the control module 130 a succession of activations and inhibitions of the circuit 121 E for amplification of the signals coming from the modulation circuit 122E.
- An amplitude modulated signal is thus obtained.
- the succession of transmissions and interruptions in the transmission of the carrier constitutes the radio signal comprising the message or, in this case, the identifier to be transmitted.
- the carrier wave can be emitted at a given fixed or variable frequency during amplitude modulation communications.
- the module 130 can also consist of a switch controlled by the logic processing unit 13 and connected in series with the supply circuit of the amplification circuit 121E.
- any information can be transmitted, at low speed, from the order receiver 10 to the order transmitter 20.
- this information can consist of an identification code or an address characterizing the order receiver.
- This identifier (or address) is by the suite used by the order transmitter to authenticate with the order receiver, this time in the context of a conventional order transmission carried out by frequency modulated signals.
- the amplitude modulated signal can be easily detected by an elementary reception module 210 integrated into the command transmitter 20.
- This command transmitter shown diagrammatically in FIG. 3 comprises a logic processing unit 23 connected, on the one hand, to a man-transmitter interface 24 of the keyboard type and, on the other hand, to a circuit 22 for modulation and transmission of frequency modulated signals.
- This circuit 22 is in turn connected to a coupling device 21.
- the transmitter further comprises, connected to the logic processing unit 23, an elementary reception module 210. This module allows the reception of amplitude modulated signals from of receiver 10.
- This elementary reception module 210 comprises a receiver circuit 211. It can be a receiver circuit of the super-reaction type consisting mainly of a transistor used in oscillation. The transistor is blocked in oscillation except for the frequency of the carrier wave used for the communication by signals modulated in frequency. The oscillations are then demodulated in amplitude and shaped by a demodulation circuit 212 translating the signal sent by the receiver 10.
- a type of reception circuit of low cost, makes it possible to easily detect at low speed, two levels of amplitude of an amplitude modulated radio signal.
- the elementary reception module 210 therefore makes it possible to receive an "all or nothing" signal coming from the transceiver 10 within a range of 50 cm to 1 m and to interpret this signal in the form of a binary code. This code is then stored in a memory of the logical unit processing to be sent in the information frames constituting the control orders issued by the order issuer.
- the installation described only includes one order transmitter. However, a plurality of command transmitters as described, as a plurality of command receivers as described may constitute an installation according to the invention.
