Definitions

• the present invention relates to a method of transmitting orders according to the preamble of claim 1.
• Such a method of transmitting orders relates for example to transmitters of orders and receivers of orders operating on the same communication network and used for technical management and comfort management in a residential building or in a building. commercial.
• a first problem encountered with prior art order receiving devices as described in application EP 0 521 818, relates to the purely sequential behavior of these devices. Thus, any new command is made after the previous command so that it is impossible to execute commands in parallel on the same command receiver.
• a command receiver When a command receiver is designed, provision is made to make it recognize and execute certain commands. Very often, we realize, after analysis of user behavior, that it would be wise to provide the receiver with new commands. However, it is too late to implement these on the products already installed and it is expensive to install these in the form of modified software modules in the new products produced.
• One possible solution to this type of problem consists in downloading new software modules to the command receiver, as described for other applications in US Patent 5,787,288.
• a short impulse is interpreted as an order of rapid movement to the extreme position, while a maintained impulse is interpreted as an order of slow movement as long as the key is kept pressed. If the discriminating value short press / sustained press is fixed at 0.3 seconds, it is only after this period that the command can be issued by the order transmitter. Thus, the total reaction time can turn out to be much higher than this value.
• the order-receiving devices can be supplied autonomously, for example with electric batteries.
• the problem is to reduce the consumption of the receiver.
• methods have been devised for periodically putting the receiver to sleep, as described in US Pat. No. 5,134,347. For example, the receiver wakes up every 500 ms and goes back to sleep mode if it does not see a broadcast.
• the transmitter of orders must transmit a signal called "wake-up frame" which lasts at least 500 ms so that this is received by a receiver.
• the actual control signal then follows this wake-up frame.
• the object of the invention is to provide a method which overcomes these drawbacks and improves the methods known from the prior art.
• the invention proposes to provide a method for transmitting orders allowing the transmission of orders corresponding to parameterized commands without requiring significant memory resources and without requiring significant network resources.
• the invention allows simple execution of commands in parallel, and / or conditional sequences of commands.
• the invention also aims to provide an installation allowing the implementation of such a method.
• the method of transmitting orders according to the invention is characterized by the characterizing part of claim 1.
• Figure 1 is a diagram of the device for implementing the method according to the invention.
• FIG. 2 is a flowchart of an embodiment of the transmission method according to the invention.
• FIG. 3 is a flow chart of the method applied to the control of a ventilation cycle.
• the EO order transmitter, RO order receiver and equipment 15 assembly shown in FIG. 1 allows the execution of the order transmission method according to the invention.
• the RO command receiver contains a radio frequency transceiver 12 connected to an antenna type coupling device 11 on the one hand, and to a processing unit 13 of microprocessor or microcontroller type, on the other hand.
• This processing unit 13 controls an actuator 14 whose electrical supply is not shown.
• the actuator 14 acts on equipment 15 such as a blind, a door, a shutter, a heating radiator or an air conditioning or lighting device.
• processing unit 13 is preferably a microcontroller, which integrates a memory area
• a memory 16 is shown here, separately, intended to contain inter alia a program for managing and executing commands.
• the EO command transmitter comprises an antenna 21, a radio frequency transceiver 22, a processing unit 23 of the microcontroller type, a keyboard type input means 24 and a memory 25.
• the bidirectional communication, represented by arrow 1, between the transmitter of orders EO and the receiver of orders RO is done by electromagnetic waves.
• the invention is based on the introduction, within the transmission frame of an order, of markers, coded on at least two bits and each associated with an order, whose function is to indicate to the receiver what are the logical and / or temporal relationships between the transmitted orders.
• An order transmission frame transmitted from the order transmitter to the order receiver contains at least: a CMD order, a MAK marker.
• the order transmission frame also contains elements for identifying the order recipient (s) of the order, and for identifying and / or authenticating the order sender.
• a program 110 When performing, as shown in FIG. 2, an action A1, consisting for example of pressing a button on the keyboard 24 of the EO command transmitter and corresponding to a series of commands called macrocommand, a program 110 is activated.
• This program 110 searches in the memory 25 of the command transmitter EO for the command commands CMDa to CMDn constituting the macro-command as well as the markers MAKa to MAKn associated with the command commands.
• Each command order CMDa to CMDn and the marker MAKa to MAKn which is associated with it is then transmitted in a frame by the transmitter of orders EO to the receiver of orders RO.
• FIG. 3 is shown the flow diagram of the method according to the invention allowing a ventilation cycle of a room equipped with a fan installed in a ventilation duct and associated with shutters allowing the opening and the duct closure.
• the action A2 on the key of the transmitter of orders EO corresponding to a short ventilation cycle has the effect of activating the program 110 which searches in memory the command orders CMD1, CMD2 and CMD3 which constitute this macro-command and the markers MAKI, MAK2 and MAK3 associated therewith. It allows then sending these orders and these markers from the order transmitter to the order receiver.
• the command associated with the CMDl command corresponds to 100% opening of the ventilation duct
• the command associated with the CMD2 command corresponds to the activation of the fan for 10 minutes
• the command associated with the CMD3 command corresponds to closing the ventilation duct.
• the program 201 stores this order and this marker in memory.
• the program 201 further tests the value of the marker MAKI and deduces therefrom that an order will be to be made after the order associated with the order CMDl.
• the command receiver then receives a second frame containing the command CMD2 and the marker MAK2.
• Program 201 stores this order and this marker in memory. It further tests the value of the MAK2 marker and deduces therefrom that an order will have to be made after the order associated with the order CMD2.
• the command receiver then receives a third frame containing the command CMD3 and the marker MAK3.
• Program 201 stores this order and this marker in memory.
• the command management and execution program 210 searches the memory for previously saved control orders and causes the ventilation duct to open at 100%, then activating the fan for 10 minutes and finally closing the ventilation duct.
• the command associated with the first order received can be executed immediately or be stored in memory in order to be executed synchronously with the command associated with the second order received.
• commands with parallel execution can be applied to the operation of a Venetian blind.
• a first order would result in the deployment of the blind and a second order would result in the orientation of the slats.
• the execution of these commands in parallel rather than in series modifies considerably the visual repercussions of activation which requires a certain time of execution.
• the example cited of the slow / fast ascent (or orientation) command depending on the duration of the support clearly shows that in both cases, the action is to be taken in the same direction, but with different speeds.
• the important thing for the user is that the ordered product begins to react as soon as possible.
• this transmitter immediately causes the sending of a command code corresponding to the slow rise, accompanied by the marker with the value 01 and indicating that the following command must be executed in series.
• the command transmitter determines whether it was a short press or not.
• the method uses a three-bit behavior marker, the truth table of which is given in Table 2.
• Eight behavior instructions can thus be associated with each command, which is enough to create a programming language integrated into the frame.
• Such a communication protocol thus saves the possibility of giving afterwards advanced and new apparent functionalities to a product, when these are in fact implemented in the issuer of orders.
• the choice of coding is of course arbitrary and the programming logic can be chosen in various ways provided that it comprises at least two association functions and a complement function and at least one test and connection instruction.
• the EO command receiver may contain an indicator of success of the execution of the command. This indicator, noted SUCS is in an active state (1) if the command could be executed.
• a marker when a marker takes the value 000, it indicates to the command receiver that the macro-command is finished. The order management and execution program must then be launched. In the event that the order issuer issues a single command, this is accompanied by the marker 000.
• a marker When a marker takes the value 001, it indicates to the command receiver that the command associated with the received command can be executed in series with the other commands. For example, if you simply want to execute several commands in series, as in the previous example with the 2-bit marker, each command will be accompanied by a marker having 001 as value and the last command order will be accompanied by a marker with the value 000.
• a marker When a marker takes the value 010, it indicates to the command receiver that the command associated with the received command can be executed in parallel with the following command. In addition, the execution results of each command are combined according to a logical AND. The final SUCS indicator is only active if each of the commands has been successfully completed. When a marker takes the value 011, it indicates to the command receiver that the command associated with the received command can be executed in parallel with the following command. In addition, the execution results of each command are combined according to a logical OR. The final SUCS indicator is active if one or other of the commands has been successfully completed.
• a marker When a marker takes the value 100, it indicates to the order receiver that the command associated with the received command can be executed in parallel with the following command. In addition, the result of execution of this command is inverted before being combined according to a logical AND with the result of the following command.
• the final SUCS indicator is only active if the first command could not be carried out and if the second command was successfully carried out.
• a marker When a marker takes the value 101, it indicates to the command receiver that the state of the success indicator SUCS must be tested after the execution of the command. The following command is executed if the SUCS flag is active, otherwise the next second command is executed.
• a marker When a marker takes the value 110, it indicates to the command receiver a particular jump command in the execution of the commands. The relative value of the jump then replaces the command code.
• a marker When a marker takes the value 111, it indicates to the command receiver a particular delay command in the execution of the commands. The timeout value then replaces the command code.
• An example shows how an advanced order can be issued to products capable or not of fulfilling it as such.
• the product ordered is a Venetian blind which recognizes in particular the commands: lowering: DWN placing the slats in a horizontal position:
• Tilth Some products have a kinematics allowing them to execute these commands in parallel, other products can only realize them in series, by first performing the descent, then in a second time the orientation of the blades.
• the command receiver When the user presses the key of the command transmitter corresponding to this DNTH macro-command, the command receiver stacks in memory the sequence of command commands and then starts execution. He recognizes that the first two commands for horizontal positioning of the TILTH blades and DWN descent must be executed in parallel. If the order receiver orders a Venetian blind allowing the execution of these two orders in parallel, it starts the execution and the success indicator SUCS goes to the active state after the execution of these commands. This is followed by a jump to the end of the macro command.
• the order receiver controls a Venetian blind that does not allow the execution of these two orders in parallel, it immediately sets the success indicator SUCS to 0.
• the DWN descent and positioning commands horizontal TILTH blades are then executed one after the other.
• the transmitters and receivers of orders described above use a wireless communication by radio frequencies and bidirectional character, but the invention can also be applied to devices with one-way communication.
• the communication can still be done by means of a wired bus type link or of carrier current type.
• the same order receiver can communicate with one or more order issuers and the same order transmitter can communicate with one or more order receivers.
• An advantage of the method resides in the fact that a single authentication operation is necessary before or after the transmission of the group of commands. This saves processing time, but also and above all, limits traffic on the network.
