Definitions

  • the invention relates to a system for equipment control, comprising a plurality of equipment and actuator units, and a common communication channel, equipment and actuator units being provided with means for comprising a unit address.
  • an equipment unit is any device present in a home, shop or other place that can be controlled according to messages on a communication channel. Examples of such equipment are lights, equipment for heating and airconditioning, video and audio apparatus, intruder alarm, application controller, and domestic appliances such as a washing machine or a coffee-maker.
  • An actuator unit is any device that may send messages into the communication channel to switch or adjust an equipment unit in response to external changes. Actuator units comprise wall switches, sensors, timers and remote control units. In its simplest form, activation of an actuator unit will switch on or off an equipment unit.
  • a system according to the introductory paragraph is the BatiBUS system commercialised by the company Merlin Gerin, Meylan, F-38240 France. A description of this system is given in the Article "BatiBUS: intelligentie via 'twisted pair'", in the magazine RB Elektronica, October 1991, p 38-40, published by 'De Muiderkring BV', Weesp, The Netherlands.
  • equipment and actuator units are linked to each other by assigning to them the same address. Such address has to be given by an operator by means of hardware switches on each individual equipment unit. The operator need to take considerable care not to confuse addresses. A reconfiguration of the system needs a careful preparation in order to assign a unique address to each group of cooperating equipment and actuator units.
  • a unit can have only one address, and the logical connection between actuators and equipment is established via said address it is not possible to link partially overlapping groups of equipment to different actuators. For example, it is not possible to switch two lights with a first actuator and to link a second actuator with only one of the two lights together with other pieces of equipment.
  • a further disadvantage of this known system is that there must be prior knowledge in the system of the type of equipment and actuator units possible and the way they cooperate when linked together. The need for prior knowledge inhibits an easy extension of the system with pieces of equipment of a new type.
  • an object of the invention to provide a system for the control of equipment in a working or living environment which is more flexible and requires less preparation when a reconfiguration of the system is desired, which allows partially overlapping groups of equipment units to be linked to different actuators and which can be easily extended with new types of equipment or actuators.
  • a system for equipment control in accordance with the invention is characterized
  • European patent application 0 296 022 describes a system with modules interconnected via a bus.
  • a module has an input and/or an output.
  • the input of a module is connected to an information source.
  • the output of a module is connected to a device, such as an indicator, which uses the output signal.
  • a functional relationship between an input of a first module and the output of a second module can be established by selecting an input on the first module and an output on the second module, displaying the selected input and output to a user, and in a programming mode storing the address of the first module, the number of the input, the address of the second module and the number of the output in both modules.
  • the modules are not functionally involved .
  • An alternative embodiment for easily establishing logical links is characterized in that the actuator unit is operative to change state in response to an event;
  • a list of actuator addresses is established. Into each of the programmable memories of the selected actuators the address or addresses of the equipment units associated with the link-signal are subsequently stored.
  • At least one equipment unit has associated with it a programmable memory for storing at least one programmable message and means for storing into the associated programmable memory said at least one message and means for emitting at least one of the stored messages via the common communication channel in response to a change of state in the unit.
  • an equipment unit may act as an actuator.
  • Equipment units and actuator units are not mutually exclusive. For example, an actuator may switch on a piece of equipment which then will operate till a predetermined condition occurs. When said condition occurs the equipment will behave as an actuator and control or switch another piece of equipment.
  • An equipment unit that may behave as an actuator is, of course, provided with means to generate a link-signal.
  • This embodiment may further comprise means for storing messages in the programmable memory of said at least one equipment unit, the messages comprising the addresses of the actuator units associated with the link signal.
  • the actuator units which are logically coupled with the equipment unit receives a message when the equipment unit changes state.
  • the message may cause a change of state in the actuator unit as well, for example, it may switch on or off an indicator in the actuator unit.
  • this return link between equipment unit and actuator is established simultaneously with the forward link between actuator and equipment units, without operator action required.
  • the system in accordance with the invention may have the equipment and actuator units comprising a further programmable memory for storing the unit address and means for storing into said programmable memory a unit address.
  • a equipment or actuator unit When a equipment or actuator unit is inserted in the system it receives a unit address via the communication channel.
  • a list of address assigned can be maintained and, consequently, the unit address may be unique.
  • This system further comprises a central unit being arranged for assigning unit addresses to actuator and equipment units.
  • a central unit being arranged for assigning unit addresses to actuator and equipment units.
  • the use of a central unit for assigning unit addresses to equipment and actuator units is advantageous as such a central unit can assemble a list of all addresses used, thereby avoiding the need for each equipment and actuator unit be provided with means to assemble such a list when inserted into the system. Duplication of such means in all units and heavy communication on the common communication channel just after switching on a new unit is thereby avoided.
  • a preferred embodiment of the system according to the invention further comprises a configuration unit comprising means for retrieving information about the interaction between equipment and actuator units from a background memory, the configuration unit further comprising means for submitting messages containing information retrieved from said background memory to the programmable memories associated with equipment and actuator units which are marked and to the equipment and actuator units associated with a link-signal, when a link-signal occurs.
  • the messages emitted by an actuator may comprise instructions for the equipment unit for which the message is intended. As the actuator has no prior knowledge of the equipment unit, the instruction part of the message needs to be obtained from a source having knowledge the set of possible instructions for that equipment unit, and stored in the programmable memory of the actuator unit.
  • the background memory in the configuration unit contains sets of instructions for the interaction or cooperation of the various types of actuator and equipment units in the system.
  • the background memory can be updated in order to store therein additional sets of instructions when new types of actuators or equipment units become available. Updating is possible, for example when the background memory is an exchangeable memory such as an optical or magnetic disk.
  • each actuator or equipment unit may have a set of instructions describing with which available equipment and actuator units it may interact and how the interaction takes place. This set of instructions is added in the course of the installation of the new actuator or equipment unit added to the contents of the background memory.
  • the instructions may be available on a card with a magnetic strip or a chip card.
  • the mark- and link-signals and the signals for storing messages in the associated memories can be transmitted via the common communication channel to and from the configuration unit.
  • a separate communication channel can be used which channel is switched off when no such reconfiguration takes place.
  • An embodiment of the system in accordance with the invention may have the programmable memory associated with each actuator and equipment unit, respectively, being physically integrated with the unit.
  • the common communication channel is not used for obtaining the messages that are to be send from an actuator to an equipment unit or vice versa. Consequently, the load on the common communication channel is significantly reduced and the communication channel may be slower and cheaper. This is advantageous especially in applications with a large number of actuators and equipment units, such as office buildings.
  • An embodiment of the system according to the invention has the mark-means in at least one equipment or actuator unit comprising a switch for marking the unit, the switch being associated with the unit.
  • Analogous the system may be further have at least one equipment or actuator unit comprising a switch for generating a link-signal associated with said equipment or actuator unit.
  • the switches may be buttons which are physically present on the housing of the actuator or equipment units.
  • the switches may be connected to a detector for remote control signals, for example infra-red, allowing the user activating the switches remotely.
  • the system may comprise a remote control unit for remotely activating, by means of wireless transmission of a signal beam, said switches for marking a unit and for generating a link-signal, the remote control unit being arranged for emitting a signal beam in a selected direction only.
  • the signal beam of the remote control is aimed at the equipment or actuator unit to be selected. For the purpose of marking and linking equipment and actuator units in the system a simple remote control unit with only two different signals is necessary.
  • the common communication channel can be an optical or electrical bus, an example of the latter is the D2B-bus, commercialised by the company D2B-systems in Redhill, England, which is described in US-A 4 429 384.
  • Preferably at least part of the communication between equipment and actuator units is by wireless transmission of signals by way of radio frequency (RF) or infra-red (IR) transmission.

  • FIG. 1 an example of a system for the control of equipment according to the invention is shown.
  • the system contains a common communication channel 10, for example a D2B-bus, which is coupled to a number of equipment and actuator units. Shown are two lights 11 and 12, two switches 13 and 14, a timer 15 which acts as a time-controlled switch, a movement detector 16, for example a IR- or sound detector, which behaves like a switch when any movement or noise is detected in its vicinity, video and audio equipment 17 and 18, a remote control unit 19 with a detector 20 and an application controller 21.
  • the application controller 21 functions as an actuator reacting on a combination of different inputs, indicated are a timer 22, a IR-detector 23 and a sound detector 24.
  • the inputs to the application controller may be directly connected as shown or communicate with the application controller via the common communication channel 10.
  • the communication channel 10 is further linked to a central unit 30 and to a memory unit 31.
  • the function of the central unit 30 is to assign unit addresses to each of the actuator and equipment units in the system.
  • the memory unit 31 comprises a programmable memory containing for each actuator unit an associated memory for storing therein the unit addresses of the equipment units to which the actuator unit is linked.
  • the system functions basically as follows. If an actuator changes state, the associated memory is accessed and messages are transmitted to the units of which an address is present in the associated memory.
  • a message may contain merely the address of a destination equipment unit, may contain a general instruction or the message may be related to the specific change of state of the actuator unit.
  • the equipment units to which a message is transferred will change their state in a way contained in or implied by the message.
  • Equipment units and actuator units are not mutually exclusive. For example, an actuator may switch on a piece of equipment which will operate till a predetermined condition occurs. When said condition occurs the equipment will behave as actuator and switch another piece of equipment such as an alarm or an indicator on the original actuator unit. Consequently, in the system the actuator and equipment units are treated as equivalent.
  • actuator unit is used to indicate units that transmit messages to other units when they change state.
  • Equipment unit is used for units receiving messages.
  • Each of the equipment and actuator units comprise a programmable address memory and means to communicate with the central unit.
  • each of the equipment and actuator units will transmit initialising messages to the central unit and in response they will receive their unit address.
  • the unit address is subsequently stored in a programmable address memory.
  • Preferably unit addresses are unique, but also the same address can be assigned to different units that operate completely in parallel.
  • the memories are preferable of a non-volatile type, for example EEPROM. Inserting a new equipment or actuator unit has as initially as effect that the new unit will be given a unit address only. In a stable configuration the central unit 30 may be switched off or disconnected.
  • each actuator unit is provided with its own associated memory containing the table of equipment unit addresses.
  • the advantage of this embodiment is that the common communication channel 10 is not used for messages from the actuator units towards the memory units 31.
  • FIG 2 a functional diagram of an actuator unit 40 is shown in more detail.
  • the actuator unit 40 can be in one of several states 41, 42, 43 or 44.
  • an 'event' occurs, i.e . the state of the actuator changes, shown in the Figure by an arrow indicating a change from state 41 to state 42
  • an internal signal corresponding to this change is generated.
  • the influence causing the change of state is, for example, a person turning a knob, a temperature reaching a predetermined value or the lapse of a time interval.
  • the internal signal is compared with the contents of a column 'events' 47 in an 'event table' 45.
  • messages in the event table 45 that are linked with said entry 46 are transmitted via the common communication channel 10. These messages comprise the destination addresses, i.e . the unit addresses of the equipment units, as stored in column 48 and possible further instructions for the addressed equipment as stored in column 49 in the event table 45.
  • a functional diagram of an equipment unit 50 is shown in Figure 3.
  • the unit 50 is connected to the common communication channel 10 via an internal interface 51.
  • the unit can be in one of several states, shown are a first state 53 and a second state 54, for example "on” and "off".
  • a message is received via the common communication channel 10, it is analyzed in the interface circuit 51.
  • the destination address comprised in the message is compared with the unit address as stored in the programmable address memory 52. Only if the two match, the message will affect the state the equipment unit is in.
  • the change of state may be implicit or explicit. With an implicit change is meant that the mere receipt of the message will cause the present state to be changed to the other state.
  • the message comprises an instruction, following that instruction the equipment unit changes to a particular state contained in the instruction. No change of state occurs if the equipment unit was already in the particular state.
  • the Figure suggests a change to the second state 54, indicated by arrow 55.
  • the equipment unit 50 may comprise further the circuitry of an actuator unit.
  • it may comprise a programmable memory with an event table 45 and means to select addresses and messages from the event table and transmit them via the common communication channel 10 if the equipment unit changes state. The change of state can be reported back to the actuator unit from which the message originated and to other parts of the system.
  • each unit is provided with a first switch 61, mark-switch. Activating this switch causes a mark-register 62 to be set.
  • the register 62 may be located in the unit and be, for example a flip-flop.
  • a link-signal generator 64 sends a link-signal via the common communication channel 10, causing all units in the system to be scanned and the addresses of those units of which the mark-register 62 is set to be loaded into the event table 45 associated with the unit of which the link switch 63 is activated.
  • this table may comprise message fields 49.
  • the message fields 49 contain, for example, an identification of the state of the unit of which the mark-register is set at the moment the mark switch is activated or at the moment the link-signal is generated.
  • the actuator unit changes state, the state stored in the message field 49 will be transmitted to the equipment unit with the stored address and this equipment unit will thereby be instructed to change its state to the state it had when the logic connection between actuator unit and equipment unit was established.
  • the main advantage of the system according to the invention is that by this procedure the actuator units need to have no prior knowledge about the equipment units. Instructions for the equipment units are retrieved from the equipment units or from elsewhere and stored in the programmable memory or event table of the actuator unit in a format that has no meaning for the actuator, but has a meaning for the equipment unit.
