Definitions
- the invention relates to a remote control system for large rooms, which works with transmitters, one or more of which cooperate with one or more decoders by means of suitable addressing.
- the decoders act on actuators, which can be switches for lights or lamp groups, which can switch emergency call systems, arm safety devices or activate motors, or for roller shutters on windows. You can also set up a heating system or switch from day to night operation.
- the invention relates to a remote control according to the preamble of claim 1.
- Such transmitters are to be optically aligned with the assigned receiver if the transmitters are operated with infrared, or they are to be otherwise tuned to a special receiver. This is complex to assemble and is a hindrance when changing room layouts in offices and factories. The advantage of bus lines, which drastically reduce the wiring requirements, is reduced again.
- the invention has for its object to develop a remote control system that is easy to assemble and easily adapt to spatial and organizational changes and brings the advantages of bus lines to full advantage.
- each decoder is assigned a reception area, in particular approximately a spherical space, or a circular area when projected onto the level of a decoder arrangement.
- the reception range is essentially determined by the device characteristics, the transmitter-receiver power and the reception conditions.
- Each reception area is assigned its own receiver address which, together with function commands, forms the telegram from a transmitter to a decoder.
- Actions of power units are understood as functions that are triggered individually or in groups by a transmitter button.
- Each recipient address is only repeated after a safety distance, which can be expressed in a multiple of reception areas.
- the remote control system enables programmed decoders to be addressed, and thus assignable actuators and consumers, without special alignment of transmitters and also with different reception areas due to factors that temporarily change the transmission properties.
- the addresses for the decoders can easily be changed. It is essential that the addresses are only repeated after a safety distance that corresponds to the maximum transmission distance of a transmitter under extreme circumstances.
- the function commands for each decoder or transmitter are advantageously composed of base addresses and key addresses which are assigned to manual controls. For devices on the market, it is advantageous to work with sixteen base addresses and four key addresses.
- the functions can be programmed using coding switches or buttons. With a basic configuration of the transmitters with a four-channel system and sixteen functions per channel, 64 functions are provided. These can be divided into sixteen base addresses, each base address in turn containing four further addresses that can be assigned to the four buttons on a handheld or wall transmitter. It can also be understood that a transmitter then contains two binary-coded switches with sixteen positions.
- the decoders have a memory between their receiver and their output, which, as an assignment table, freely programmably assigns the received address to actuators which are connected to the output of the decoder via bus line.
- the decoders can be connected to one another in a grid-like manner by bus lines and can be connected to actuators by further bus lines. Due to the memory used as an assignment table, the actuation of the actuators can be easily selected and changed.
- the safety distance is advantageously chosen in commercially available devices so that it is in four reception areas in each coordinate direction. This results in an address system for sixteen reception areas. Sixteen reception areas with 1024 functions result in 1024 addresses. If infrared is the transmission medium, a ten-bit address must be provided in the infrared telegram. The memory for an assignment table or an EEPROM must then contain at least a size of 64 + 1 memory locations, since the address of the reception area can be stored in a single address.
- the distance between the centers of the reception areas is advantageously chosen to be as large as the diameter of the reception areas. This allows the spacing of the center points to be adapted to the spatial grid of a building, and at the same time ensures that the area of a grid unit can be served by a single reception area.
- the radius of a reception area is then the square root of the sum of half the squares of the distance.
- sixteen reception areas, i.e. four reception areas per imaginary coordinate axis there is then a safety distance of four times twelve meters, i.e. 48 meters. After that, an address repetition is possible for neighboring further reception areas.
- the remote control system according to FIG. 1 works with transmitters 1, one or more of which cooperate with one or more decoders 2 by means of suitable addressing.
- the decoders switch actuators, which are to be presented in connection with the associated decoders via cables.
- Each decoder 2 is assigned a reception area 3, approximately a spherical space. In the projection onto a plane in which the decoders 2 are arranged, a circular area results.
- the reception range is determined by the device characteristics of transmitters 1 and decoders 2, the transmitter-receiver power and the reception conditions.
- Each receiving area 3 is assigned its own receiver address which, together with function commands, forms the telegram 4 of a transmitter to a decoder, according to FIG. 2.
- FIG. 2 In the exemplary embodiment according to FIG.
- the decoder 2 can be mounted on the ceiling or a suspended false ceiling.
- the transmitters 1 can be designed as wall transmitters, as is illustrated on the left-hand side of the hall floor plan, or else they can be attached at a location that is directly or indirectly accessible for manual operation, as is illustrated by the upper transmitter 1 in the plan view.
- the building walls 5 in the hall limit the effect of the reception areas close to the wall.
- a transmitter 1 can have a greatest range 6, which should lie within the detection range of the decoder arrangement of an address system.
- the decoders 2 are advantageously arranged such that the distance between the centers of the reception areas 3 is as large as the diameter of the reception areas. If the distance 8 between the centers of the reception areas is twelve meters, a spatial grid results, the spatial axes 9 of which are also spaced apart by twelve meters. The smallest room unit bordered by spatial axes can be supplied by a reception area 3.
- the decoder 2 is spaced a half distance 8 from the center points of the reception areas, that is to say by a distance 10 from the sides of the raster unit, in the exemplary embodiment in each case by six meters. This also corresponds to the distance from the spatial axes 9.
- the decoders 2 are preferably connected to one another in a grid-like manner by bus lines, which continue in extensions and branches to respectively connected actuators.
- a telegram 4 sent by a transmitter 1 according to FIG. 2 is sent to a decoder 3 of an address system with the assignment table 11 or is transmitted by infrared radiation.
- the telegram 4 is composed of a receiver address 12, also referred to as Ek, and of function commands 13, which in turn are composed of base addresses 14, also referred to as Bm, and of key addresses 15, also referred to as Ta.
- the telegram 4 has sixteen receiver addresses 12 of an address system and 64 functions from sixteen base addresses 14 and four key addresses 15.
- the functions 13 are assigned the desired actuators in the memory serving as allocation table 11. This is done in a matrix 16 for functions. Addresses of the base addresses 14 are reserved for special functions in a matrix 17 for special functions.
- the matrix 17 for special functions which corresponds at least to all decoders of an address system, allows a specific actuator or a specific group of actuators and thus the associated consumers to be acted upon or switched by any of the transmitters in the system. For this it is necessary that the decoders 2 of an address system are all connected to one another and to the actuators by bus lines 22.
- a particular decoder 2 is physically assigned to a recipient address 12.
- the evaluation can expediently be carried out in such a way that a decision routine 19 queries whether the received recipient address 12 matches the recipient address of the decoder 2 or the corresponding reception area 3. If this is confirmed with the decision “yes”, the issuing of the function commands 20 on the bus line is released. If the decision routine 19 leads to the result “no”, it is checked in a subsequent decision routine 21 whether a special function is present. In the case of "yes”, the issuing of the function commands 20 on the bus line, in this case the special functions, is nevertheless released. Otherwise, the sending is not released, since the receiving decoder with its reception area should not be addressed by the telegram sent.
- a transmitter with manual controls is shown in supervision. It has four buttons 23 for functions that can be operated by hand. Infrared light can be emitted via a suitable window 24 without any appreciable preference for one direction.
