Definitions
- the present invention relates to a method and a device for converting coded remote control signals, in which a pulse train received via a high-frequency feed is converted into a digital data word and compared with a stored code word in order to trigger at least one predefinable function after a possibly positive comparison result.
- the corresponding device essentially consists of a receiver for receiving the remote control signals from a corresponding transmitter in the form of pulse trains, the receiver having: a) a current / voltage supply,
- the conventional methods and devices are essentially limited to activating the receiver and the aggregates connected to it by actuating a transmitter, this activation process then triggering an opening or closing of the garage door depending on the prevailing state.
- the purpose of the coding is to trigger the activation of the receiver only when a specific, precisely coded, pulse train has been received by the associated transmitter.
- a code can be set on the receiver of the known system, which corresponds exactly to the code of one or more specific transmitters, so that the desired function of opening or closing a garage door was only triggered when the receiver had received a pulse train that exactly matched the set code corresponded.
- the pulse train originating from the transmitter and received by an HF receiver is fed to a demodulator, preferably with gain control, which converts the pulse train into a digital signal, i.e. typically into a sequence of voltage values at two different levels, which one can assign a logical "0" or "1".
- This system has the disadvantage, however, that even if a user only wanted to operate a certain garage door using the remote control, for example, the corresponding transmission pulse may also have been received and accepted by the receiver installed at the gate entrance, so that the corresponding one is also unintentionally Gate entrance was opened.
- a further limitation of the known, relevant systems which are usually used for remote control of garage doors or gate entrances is that they essentially have only a single output, which is either active or not after receiving a transmission pulse. So it is not possible to have different functions independently trigger.
- the output of the receiver can also be connected, for example, to a switching relay for lighting, but this means that when the door operator is actuated, the lighting is also switched on regardless of whether this is in of the respective situation is required or desired or not.
- an automatic switch to reverse to the other process, depending on whether an opening or closing process was previously completed, and in this respect possibly also to a second output was possible with the methods and devices according to the prior art. In the sense of the present invention, however, this corresponds only to the control of a single function.
- Infrared or ultrasonic remote control devices for television sets, video recorders and stereo systems are known from everyday use. Although these are capable of triggering various functions, they cannot be coded for specific users and, above all, have the disadvantage that they can generally only work with a line of sight between the transmitter and receiver, since infrared and ultrasonic waves do not penetrate walls or other obstacles , in contrast to the radio frequency waves with which the coded remote control systems according to the present invention are usually operated.
- the present invention has for its object to provide a method and an apparatus with the features mentioned above, which combine the encodability and ability to work without line of sight between the transmitter and receiver with greater design options and freedom in the application to different functions .
- this object is achieved in that at least one piece of information about at least one function assigned to the code is stored in the memory of the receiver together with a code word, that the data word sent also contains the information about a function to be triggered in addition to a code portion and that Comparison of the received data word with the stored data includes the comparison of the information about the function to be triggered.
- the data word sent can be understood as a code word, in which in principle any section or area is reserved for additional information.
- this data word is compared with a stored data word, but a specific function to be triggered is now assigned to this stored data word, while at the same time different data words are definitely the same Functions to be triggered can be assigned if they coincide in the information section of the code word, that is, the area reserved for the additional information mentioned.
- the term "function to be triggered" is to be understood very comprehensively. For example, two functions to be triggered are considered different if different outputs of the receiver are activated.
- functions to be triggered can also be regarded as different in the sense just described if one and the same output is actuated with a different time behavior, for example delayed, "flashing", as a string contact, as an impulse or in some other form.
- Such differences in the functions to be triggered can also be triggered in a controlled manner in that the data words sent differ in their code component, while the part reserved for the information mentioned remains the same. For example, different users could control the same output with their transmitter on the receiver, but this would then show different timing, if necessary.
- the entire data word sent is processed logically as "code”, although in the narrower sense under the term "code” that portion of the data word sent and received that would always remain unchanged with one and the same transmitter while different transmitters would be viewed make a fundamental distinction in these code sections (insofar as this is possible according to the length of the code portion and the number of transmitters produced overall).
- the portion of the data word reserved for the additional information or a function to be triggered is the same for different transmitters if the same function is to be triggered with it, that is to say if, for example, the same channel is to be controlled.
- the method according to the invention still offers the freedom to use the pure code component as additional information for the function to be triggered, for example with regard to the timing behavior already mentioned, since a certain function including the timing behavior is logically assigned to the entire data word sent and stored identically.
- the receiver can now trigger completely different functions independently of one another, such as, for example, switching on a light and actuating a garage door.
- the receiver could open and close two or more different gates arranged side by side or one behind the other, independently of one another, so that it would be possible, for example, to allow a user access to only one of the gates or to a certain group of gates, while other users have different access rights.
- the transmitter now also provides information about the one to be triggered Function is sent out, while the receiver not only compares whether the relevant code word is stored and thus indicates the basic access authorization of the user, but also checks whether this code word is also stored in connection with a specific function to be triggered, since only then is the authorization for triggering this particular function.
- the method according to the invention can be used meaningfully even if only a single function is to be triggered, for example in the case of closely spaced receivers which are to be actuated independently of one another by the same transmitter (in this case the information unit about the function to be triggered can be used as an extension, so to speak of the code), but an embodiment of the method is preferred, in which at least two different functions can be triggered by the recipient concerned.
- a variant of the method according to the invention provides that the data word sent out by the receiver, at least insofar as it includes the code word portion and the information data about information to be triggered, possibly including its timing, is interpreted and treated as a code word by the receiver, with the receiver expanding in addition to this Codeword the information data for the function to be triggered and their timing behavior are stored.
- the number of different functions to be triggered is in principle not limited and only depends on the practical circumstances and requirements. According to one embodiment of the invention, eight different outputs are provided on a receiver according to the invention, for example.
- these functions could consist, for example, in triggering various units, such as 1. a common gate entrance, 2. path lighting, 3. a garage door, 4. garage lighting, 5. a lifting platform in a double parker, 6. a lock actuation for an access door between the garage and a staircase, 7. a staircase lighting. It would also be possible to trigger all of these functions simultaneously or immediately in succession by pressing a single button if the transmitter is set up accordingly. In such a case, an embodiment of the method according to the invention is particularly preferred, in which the individual functions can be triggered with a time delay, with these time delays preferably also being individually adjustable.
- the above-mentioned functions can then be triggered in sensible increments, so that, for example, the last-mentioned function "switching on the stairwell light" is only triggered when the user has entered the driveway with his vehicle, possibly also into the garage and straight out of his Vehicle gets out. At this point in time, for example, the closing of the entrance gate has long been completed.
- the data word in question contains, in addition to the information about the function to be triggered, also the information about the extent of a specific time delay with which the function is to be triggered, if not generally assigned to a specific function, but once a time delay which can be changed becomes.
- the data words serving as a basis for comparison and stored in the relevant receiver are stored or entered into the memory by switching the receiver into a so-called "learning state" and that the transmitter is then actuated in accordance with the desired function, whereby the transmitter sends out a pulse train which corresponds to a data word which contains, from the code word, information about the function to be triggered and possibly also information about a corresponding time delay.
- the sensitivity of the receiver system in the learning mode is reduced considerably, preferably by at least 10 dB.
- the transmitter in question has to be brought very close to the receiver so that it receives and stores the transmitted code, including the other information, while, at the same time, transmission pulses emanating from other nearby transmitters due to the very low sensitivity of the receiver not be recorded and registered by this.
- This ensures that only the code and the associated functional information of the transmitter that is brought very close to the receiver specifically for this purpose are actually transferred to the memory of the receiver.
- a particularly preferred embodiment of the method according to the invention is one in which the internal clock frequency for reading and comparing the received and stored data words is at least one order of magnitude below the transmission frequency of the associated FH system.
- the internal clock frequency of the evaluation logic of the system is at most 1/10 of the transmission and reception frequency of the transmitter and receiver.
- An even larger distance is preferred, in which, for example, the internal clock frequency for data comparison is below 1 MHz, better still below 100 kHz and in the preferred embodiment 32 kHz, while the transmission frequency is above 10 MHz, preferably at 27 or 40 MHz .
- the frequencies in question are separated by approximately three orders of magnitude (a factor of 1000), so that mutual interference due to crosstalk between the transmission frequency and the clock frequency is practically excluded.
- the method according to the invention works extremely quickly and in no way slower than conventional methods if the individual bits or information units of the data words are respectively read out in parallel from the data memory and compared with the received data. With a clock frequency of 32 kHz and a complete parallel readout of the entire data word including code information and information about the function to be triggered or time delay, 32 complete data words could be compared within a thousandth of a second and corresponding functions could be triggered.
- the object on which the invention is based is achieved in that the interface has a plurality of outputs for different functions and in that the evaluation logic has a structure or programming which assigns any code word registered in the memory to each of the outputs allowed.
- the memory management has parallel access at least to the data units of a data word that indicate the function to be triggered, preferably the data words are accessed in parallel over the entire word width.
- An embodiment of the invention is particularly preferred in which at least the decoder, the memory and the control logic are accommodated on a common semiconductor circuit or chip.
- the parallel access of the control logic to the memory can be easily integrated into the system and the decoding of the received data words, their evaluation and the triggering of the associated function can be carried out very quickly within a few cycles of an associated clock generator.
- a clock generator is provided, the frequency of which is at least one order of magnitude lower than the transmission frequency, the clock frequency preferably being 42 kHz, while the transmission frequency is at least 27 MHz.
- a time delay element is connected between the control logic and the outputs, for which the time delay can preferably be set.
- the control logic can extract information about the extent of the desired time delay from a stored data word which corresponds to a transmitted data word with regard to code and function specification, and set the subsequent time delay element in the desired manner, so that the output in question only after one corresponding time delay, measured from the time of the positive data comparison, is triggered.
- the data word sent can also contain corresponding time delay information, which can also optionally be included in the data word comparison or transmitted to the control logic and the time delay unit without comparison.
- the memory has a minimum size of 30 data words, each of which has a word length of at least approximately 60 bits, which corresponds to a total memory size of approximately 1800 bits.
- the memory has a minimum size of 30 data words, each of which has a word length of at least approximately 60 bits, which corresponds to a total memory size of approximately 1800 bits.
- a word length of approx. 60 bits has proven to be completely sufficient to provide a sufficiently long code word in the order of 20 to 24 bits, 8 bits of information about the function to be triggered, 8 bits of information about a possible time delay or activity duration of an output as well other bits, for example check and check bits, bits for marking the end of a word and the beginning of a word etc.
- the figure is a schematic representation of the receiver according to the invention with its periphery, but without a high-frequency receiving part and without units connected to the outputs.
- chips 100 schematically represent the contacts of chip 100.
- the signals coming from a transmitter are received, amplified and passed on to the demodulator 10 with the aid of an antenna and a subsequent high-frequency part, which are not shown.
- the received pulse train is demodulated in the demodulator 10 and thus converted into, for example, a 60 bit long digital data word.
- the demodulator 10 passes this signal on via the input 12 of the chip 100.
- a control output 11 of the chip is connected to a control input of the demodulator in order to reduce the sensitivity of the demodulator for a programming or learning process, so that in this mode only the signals to be learned or stored from a transmitter placed in the immediate vicinity of the receiver are left can be received to rule out interference and incorrect storage.
- a complex integration filter 101 which has the function of a signal shaper, connects to the serial input 12, as a result of which the width fluctuations of the individual bits are compensated for and the signal level, if necessary, is additionally leveled.
- 112 is a general term for internal data lines of the chip 110, which can be both serial and parallel bus lines.
- Block 107 schematically designates a comparator; block 102 is a memory, in the example shown with a memory volume of 6 KB, 103 denotes an address management for the memory and 108 an evaluation logic.
- the pulse train converted by the input filter 101 into a sequence of uniform, digital data bits is first checked to see whether it represents a valid data word at all, e.g. with a length of 60 bits and special bit sequences, e.g. Characterize the beginning and end of the word, with so-called check and check bits also being checked, as a result of which any faults in the transmission of the data are to be recognized and faulty data words are to be eliminated.
- the comparison then takes place with the data words stored in the memory 102. If a valid data word has been found, ie if a match of the transmitted data word with one of the stored data words has been determined, it is checked whether this word has already been received immediately before or within a predeterminable, previous time interval. The frequency of the reception of a specific, valid data word is registered in a counter either in succession or else within a predefinable time interval. After this counter a predeterminable Has reached or exceeded the limit value, the command to trigger the function, which is to be triggered according to information contained in the data word, is regarded as valid and a corresponding trigger command is initially passed on to the timer 109.
- the timer 109 has eight different outputs, labeled 80 to 87, each of the outputs 80 to 87 being preceded by a time delay element within the timer 109.
- Each of the outputs 80 to 87 can be assigned a specific, fixed time delay, however, if necessary, the information about a specific setting of a respective delay element can also be passed on from the stored or received data word to the timer, which then has a corresponding value for the respective time delay element sets.
- the delays are preferably set in stages and in digital form, with the individual outputs 80 to 87 being able to be assigned different maximum delay ranges.
- the time delay for opening an external gate for example, in front of which, for example, a vehicle is at the moment an opening command is sent, can be set to zero and the associated output channel 80 either does not require a delay element at all or one that allows time delays in the range of a few seconds at most .
- other time delay elements for other outputs can be set, for example, gradually in the range from a few seconds to minutes or even hours.
- the timer 109 and its time delay elements and outputs can also be optionally designed so that they activate the associated output not only at a certain delayed time, but also so that this activation during a predetermined time interval or until a trigger Stop command remains active. Furthermore, it is possible to design individual channels of the timer so that after the receipt of a valid trigger command, the associated output is activated intermittently, which would cause the lamp to flash, for example, when a lamp is connected. Finally, the evaluation logic and the timer can also be designed in such a way that a specific output remains active during a specific, preferably small time interval beyond the receipt of the last valid data word with the relevant function selection. This means that, apart from a small time delay corresponding to the interval mentioned, an output remains active as long as the transmitter sends out the relevant data word (so-called streak contact).
- the so-called programming mode is considered below.
- the programming mode is used to enter certain data words in the memory 102, so that later when a data word of this type is received, a specific function which is also desired in this data word possibly triggered with an additional desired time delay or a largely predefinable time behavior (flashing, activation duration).
- the switch 40 consists of two pushbutton contacts 41 and 42. A brief actuation of the contact 42 leads to a switchover to the programming mode, ie the output 11 is activated and the sensitivity of the demodulator is thereby reduced.
- the output 80 of the timer 109 is first selected or addressed. A further actuation of the pushbutton switch 42 switches through to the following output 81, etc., until after a cyclical run through the outputs 80 to 87 a further actuation of the pushbutton switch 42 selects the output 80 again.
- the push button 41 is used to select a specific function.
- the function selection is shown in Table 1 below.
- the selected output and then also the function can be read on the two-digit LED display 50. If a function with a specific time behavior has been selected for a selected output, then 16 different time ranges can be selected at the BCD input 20 via a specific switch combination of the four BCD switches.
- All this information about the selected channel, the selected function with its time behavior and the time range are stored together with a code word which has subsequently been received via the demodulator with its reduced sensitivity.
- the corresponding transmitter which sends out a specific code, is actuated in the immediate vicinity of the receiver.
- the relevant code word together with the information set at the inputs 43 and 44 including the time frame information from the BCD switch 20 is stored in a 60-bit data word in the memory 102 saved.
- the entire RAM memory 102 is checked to determine whether the entire data word may already have been saved, which may be overwritten, otherwise a new, empty memory location is described.
- This method requires at least 3 bits for the information about the channel selection, i.e. the information about which of the eight outputs of the timer 109 is to be activated, and at least 4 bits for the function selection, ie for the specific time behavior of this output according to Table 1. Overall, one expediently provides at least 8 bits for the two aforementioned information. Another 4 bits of the BCD inputs 20 contain the information about the entire available time frame. During programming or during learning, all of this information is stored together with the data word which is emitted by the transmitter and is detected via the RF receiver, the demodulator 10 and the serial input 101. As soon as exactly the same data word has been received twice in succession, it is stored together with the aforementioned information in the RAM memory 102.
- the data word sent by the transmitter can consist, for example, of a 20 to 24 bit long codeword permanently assigned to the transmitter and also some changeable additional bits, which are changed, for example, by actuating different keys or key combinations on the transmitter. Corresponding keys or key combinations could, for example, be labeled with the different functions that were specifically "learned" during programming during the relevant key press.
- the receiver in a later comparison, the receiver almost identifies all of the information originating from the transmitter as a code word or comparison word, the presence of which is checked in the memory 102. If this "code word" is located, it triggers the associated functions at the associated output or channel.
- the actual code word of the transmitter is not changed, but the bits assigned to a specific function in the transmitted data word change. Since the same key or key combination of the transmitter was also pressed beforehand during programming, this correspondingly changed data word has been stored in the memory 102 together with the assigned channel and function information. If the same key or key combination of the transmitter is actuated again later, the data word in question is only found in the memory 102 together with this channel and function information, which was previously stored in the memory 102 of the receiver during programming with the same key press on the transmitter. This generally gives a clear association between a specific key press or a key combination on the transmitter and the function to be triggered, so that the transmitter buttons can be labeled or labeled accordingly.
- the user is completely free to assign any output channels and functions to any key or key combination on the transmitter.
- the same transmitter word is simply "learned" in the programming mode with correspondingly selected channels and functions via the inputs 43, 44, in that the same transmitter word is transmitted for different selected channels, i.e. the same transmitter key or key combination is pressed.
- the logic 108 finds the relevant data word two or more times in the memory 102, in each case together with different channel or function selections, so that the timer 109 accordingly has a corresponding number of channels with the controls the time behavior selected and stored in the memory 102.
- the programming of the system is facilitated in that the selected channels are indicated by numbers and the selected functions by letters or special characters according to Table 1 via the display controller 111 on the LCD display 50.
- the letters "S" and "I” are simply distinguished from the numbers "5" and "1" by a period behind them. It is also next to it possible to display the digits only in the right segment field, while single letters are displayed in the left segment field. Characters in both segment fields are always letters.
- EEPROMS 60 are provided, which are connected to outputs 61, 62 of an EEPROM controller 110 integrated in the chip.
- a mode in which a specific memory location is deleted is also conceivable for the function and channel selection.
- the EEPROM controller 110 starts reading all the data stored in the EEPROMS 60 into the RAM memory 102.
- the chip 100 can also be equipped with further elements, not described in more detail here, in particular also with a test circuit 120 and corresponding test connections 121. especially those of the serial input 101, the comparator 107, the logic 108, the timer 109 and the address control are permanently programmed or "hard-wired", i.e. Changes in the functional sequence are not programmable, but only memory contents in the memory 102 can be changed, which ultimately only allows a selection of different channels and a selection of the time behavior for each channel within the scope of the options specified in Table 1.
- the operating cycle of the chip 100 is determined by the oscillator 104, which in turn is stabilized by an external quartz with a nominal oscillation frequency of 32 kHz via the inputs 31, 32. Since the internal data bus width corresponds to the length of the stored data words when accessing the memory 102 and when comparing with the received data words, a full word comparison can accordingly take place with each clock cycle, so that even if a multiple data word reception and comparison for triggering one Function is assumed, the processing time for the data word until the function is triggered is negligible and is typically in the range of or below a thousandth of a second.
- the receiver according to the invention thus fulfills the function of a group of remotely controllable relays with arbitrarily predefinable time behavior and with a simultaneously restricted access authorization in accordance with the stored transmitter codes.
- a single receiver can trigger a large number of units and perform different functions, any assignments between certain transmitters and functions that can be triggered by them can also be made.
