DE102008006751A1 - Remote control e.g. remote control key for car, operating method, involves signaling feedbacks by remote control to user, where feedbacks indicate commands that are not transmitted and/or executed - Google Patents

Abstract

The method involves detecting a problematic case in which transmission and/or execution of commands is not performed. A set of feedbacks are tactually, acoustically or optically signaled by a remote control (1) to a user (4), where the feedbacks indicate the commands that are not transmitted and/or executed. Another set of feedbacks are signaled to the user in an operating case, so that the latter set of feedbacks indicates the commands that are transmitted and/or executed. Transmission characteristics of the remote control are adjusted in the problematic case. An independent claim is also included for a remote control for wirelessly transmitting commands to a device.

Description

The The invention relates to a wireless remote control, for example Medical devices, such as a remote control for an x-ray machine or a wireless nurse call system, or in manufacturing, such as a wirelessly connected actuation button to trigger a manufacturing step, or for Vehicles, such as a radio key.

at a remote control, which for sending a control command via a wireless interface is used, there is a risk that one Users of the remote control, for example, by pressing pressed a button, but the wireless transmission is disturbed and thereby no execution of the sent Commands done. In some cases it is for a user not obvious that no execution is done. For example, there is one in a parking lot parked vehicle the danger that the radio signal on purpose is disturbed by a jammer and so on Command to close the vehicle is not transmitted to the vehicle becomes. The vehicle can then easily be stolen or items be stolen from the vehicle. For a wireless remote control for a nurse call system there is a risk that a sent command to call a sister by a deliberate or random interference of the wireless transmission channel is not received and so in the nurses' room no alarm he follows.

at Radio remote controls for cars is known to open successfully and / or closing is signaled by the car to Example by briefly flashing the turn signals, switching on the vehicle or the interior lighting, or by a short horn signal.

Each known for itself is monitoring whether a Radio channel is occupied, as well as the provision of feedback information with a remote control. However, this is the feedback information from the remote-controlled device to the remote control and there suitably represented to the user, for example optically, acoustically or by haptic vibration.

So For example, a is a monitoring of a radio channel executive channel access method for radio communication it is known in which, before sending, it is observed whether the radio channel free is. This is to avoid collisions, d. H. one simultaneous transmission through two stations. Such a function is for example a wireless local area network (WLAN) known as Distributed Coordination Function (DCF), which in the form of a channel access corresponding to one as a Carrier Sense Multiple Access with Collision Avoidance (CSMA / CA) known method is realized. The CSMA / CA procedure provides that a Sendewillige station a wireless medium, such as a Radio channel, checks if it is free or busy, by listening to this. If the medium is busy, wait the station until the end of the current data transmission.

By US 2005/0085956 A1 is a remote control with feedback function known. A remotely operated vehicle transmits a feedback signal to a portable remote control device, for example for remote control of an air conditioner. The feedback signal is generated when a set or desired internal temperature is reached, for example by activating the horn of the vehicle. The feedback signal is not necessarily sent to the remote itself.

By WO 2007/010445 A2 It is known to influence bulbs remotely, for example in their color or brightness. The light source has a sounder so that it can output an acoustic feedback signal, by which it can be seen that the light bulb has received a command signal. A variant in which the feedback signal is signaled by a change in the light is through WO 2007/010470 A1 known.

By US 2005/0066969 A1 For example, a wired remote control of a medical device is known that provides tactile feedback of a parameter of a patient being treated.

WO 2007/050218 A2 describes a remote control, for example, for a model vehicle in which driveability limitations depend on the remote control used and a selected preset, and in which a user experiences a real driving sensation in the form of noise and vibration of the remote control as well as over time and conditions of use is simulated changing driving characteristics of the model vehicle, for example, to play tight turns through noise, speed levels due to vibration, and required tank or pit stops by changing driving characteristics.

By CA 2 547 595 A1 For example, a remote alarm display provided as an extension to a vehicle security system in the form of an anti-theft alarm system is known. An alarm signal is wirelessly transmitted from the vehicle to a remote device that displays the alarm visually, acoustically or by vibration.

An object of the invention is a method for operating a remote control, which Commands for execution by a device wirelessly transmits to this, as well as to provide a corresponding remote control, which method or which remote control provides improved protection against an unnoticed, failed execution of a wirelessly transmitted command.

The The object is achieved by a method according to claim 1, as well as by a remote control according to claim 12th

Preferably the feedback is at least in case of problems by a vibration tactile, by a warning tone acoustically, by a flashing display, for example by a flashing LED, optically, or by a combination of these Possibilities signaled. Such feedback takes place either only in case of a problem, or in the case of a problem another Type of feedback as in good case. This will alert the user made, that a problem case exists or could be present. As a result, he can pay attention to it with increased attention and if necessary, check whether a desired action also actually happened.

A advantageous embodiment of the invention Procedure provides that in the case of one before a wireless transmission of a command or control command recognized problem case corresponding feedback signaled and no command sent or the command is sent and feedback is signaled that the command may not be reliable was executed.

A Another advantageous embodiment of the invention Procedure provides that in a recognized problem case an adjustment the transmission behavior of the remote control takes place.

he follows.

Preferably, detection of a problem case in which a transmission and / or execution of a command does not or possibly does not take place and / or took place includes monitoring a wireless transmission link, for example a radio channel. Thus, for example, a suspicion of an existing interferer can be deduced when a signal level is too high, ie exceeds a predetermined threshold. Observing a wireless transmission link, for example a radio channel, is particularly relevant in Industrial, Scientific, Medical (ISM) radio bands, as they are freely usable. In addition, it is possible to transmit according to the CSMA / CA method, whereby, for example, a radio channel is observed before sending and waiting for a free channel. If there is a long wait, a problem is suspected or there is a problem. It is also conceivable that when watching egg ner wireless transmission line on a reception of a permanent and / or sent at certain time intervals, also known as beacon message message or other message of a counterpart device forming, for example, in a also referred to as broadcast, constantly or at certain times sending the remote station is maintained. Failure to receive an expected beacon message or low signal strength indicates a problem. In addition, a two-way communication with the device is conceivable, wherein waiting for receiving a confirmation message when watching a wireless transmission link. A problem case can be detected at a failure of the confirmation who the.

One Watching a wireless transmission link or watching Radio communication or reception of beacon messages is preferably carried out before and / or during and / or after sending.

A advantageous embodiment of the invention Procedure provides that several types of commands with the remote control be sent, with the feedback preferably only some these commands occur, especially for particularly critical ones Commands, for example, only when locking a car, but not at an opening, at a nurse call system only at an emergency call, but not for general signals to request an uncritical service.

Preferably is a problem-signaling feedback already before the triggering of a command, for example by a status display, that a disturbed channel or a special test mode exists.

Specific Fields of application of the invention relate to a wireless interlock a vehicle, a wireless arming of an alarm system, and a wireless paging system in which patients over have a wireless emergency button, for example to reduce the installation work for outside regular hospital room occupied beds, for patients on the way to examination and treatment rooms in Hospitals, for mobile patients or older Residents in a care facility and the like.

A second object of the invention relates to a remote control which transmits commands or control commands for execution by a device, for example by radio, infrared or ultrasound wirelessly to the device. According to the invention, the remote control comprises means for detecting a problem case in which a transmission and / or execution of a command is not or possibly not and / or occurred, as well as means for signaling a feedback to a user at least in a problem case, thereby failing to do so or, if suspected, transmission and / or execution of a command or control command may have been made known. The remote control can determine information that a problem exists in different ways:

• - Watching a wireless transmission link, such as a radio channel. If a signal level is too high, a suspicion of an existing interferer can be deduced. This is particularly relevant in Industrial, Scientific, Medical (ISM) radio bands, as they are freely usable.
• - Receiving a permanent and / or sent out at certain time intervals, also known as a beacon message message or another message from a remote station, such as a designated in a broadcast, constantly or at certain times sending remote site.

• In the case of a two-way communication, a problem case can be recognized by an absence of a confirmation.

there may be watching radio communication or receiving beacon messages can be done before, during and after sending.

In One training can have several types of commands be sent with the remote control. The feedback in the sense of Invention takes place in a variant only at some of these commands, especially for particularly critical ones Commands, for example, only when locking a car, but not at an opening, at a nurse call system only on an emergency call, but not on general signals requesting a uncritical services.

In a variant, a warning of the user that a problem may occur when sending a command, even before the triggering of a control command, for example by a status indication that there is a disturbed channel or a special test mode.

The has remote control according to the invention preferably also via means for signaling a feedback to a user at least in a good case, thereby this to a completed transfer and / or execution a command or control command is made aware. The Means for signaling a feedback in case of problems and the Means for signaling a feedback in good case are preferred identical, but in the problem case, another signaling of the feedback takes place, as in the Gutfall. The means of signaling a feedback give the feedback tactile, at least in case of problems by a vibration, by a warning tone acoustically, by a flashing display, for example by a flashing LED, optically, or by a combination of these possibilities out. Such feedback is either only in case of a problem, or in the case of a problem, a different type of feedback than in good case. This will alert the user to that Problem case exists or could be present. This can he should pay attention to this with increased attention and, if necessary, follow-up whether a desired action has actually taken place.

The Means for detecting a problem case can be a for Send the command provided antenna, or a separate Sensor for detecting a wireless transmission environment, for example, a radio environment.

The Remote control according to the invention has Means that allow her, the invention Execute method and thus the advantages of the invention Process to use.

embodiments The invention is illustrated in the drawings and in the following explained in more detail. Show it:

1 a schematic representation of a wireless remote control according to the invention with feedback function on an executed or not executed or possibly not executed command.

2 a schematic representation of a flowchart of a first embodiment of a method according to the invention.

3 a schematic representation of a flowchart of a second embodiment of a method according to the invention.

1 essentially shows a remote control 01 with a button 02 as well as a facility 03 to give feedback to a user 04 the remote control 01 , a machine 06 with one over a wireless transmission line 05 or wireless connection 05 , For example, a radio channel 05 , by the remote control controllable function 07 , here by way of example a lamp 07 , as well as a barrier 08 , here an example of a visual barrier 08 , About the wireless connection 05 becomes the function 07 of the device 06 controlled or is the function 07 of the device 06 controllable. The barrier 08 Although, for wirelessly transmitted signals, in particular radio signals, penetrable, makes it difficult for the user 04 to recognize if one over the button 02 at the remote control 01 triggered desired command or control command actually from the device 06 was implemented.

In the 1 illustrated, inventive remote control 01 , which control commands wirelessly, for example by radio, infrared, or ultrasound to a device 06 transfers, instructs a facility 03 or possibility 03 for feedback to a user 04 auf, whereby this on a failed or even on suspicion possibly not done transfer or execution of a command or control command to the device 06 is made aware. This case is referred to below as a problem case, whereas a completed transfer or execution of a control command is referred to below as Gutfall. The feedback in the problem case can be tactile in particular by a vibration, by a warning tone acoustically, by a flashing display, for example by a flashing LED 03 visually, or by a combination of these possibilities. Such feedback is either only in case of a problem, or there is a different kind of feedback in case of a problem than in case of default. This will be the user 04 made aware that a problem case exists or might be present. This allows him to pay attention to it with increased attention and, if necessary, to check whether a desired action has actually taken place.

The user 04 press the button 02 the remote control 01 to order a command to the device 06 to send, for example to the lamp 07 off. If, for example, the direct view of the lamp 07 is hampered, for example because it is at the barrier 08 there is a room partition and the lamp 07 located in a different room than the user 04 Thus, the user may not be sure whether the desired action has actually been performed. This is all the more the case with hardly recognizable actions, for example, closing a door of a vehicle or arming an alarm system, which is either not displayed at all or only by a signal light.

To detect if there is a problem, the remote control 01 the antenna provided for sending the command 09 use. However, a separate sensor for detecting the radio environment may also be provided.

If the presence of a problem has already been detected before sending a control command, the remote control can 01 either give only appropriate feedback and do not send a control command, or alternatively they can send the control command but give feedback that the control command may not have been executed reliably.

Farther the send behavior can be adjusted if before sending Problem case is detected, or alternatively during or a problem case is detected or detected after sending. This adjustment can be done:

• By increasing the transmission power,
• - by a multiple sending of the control command or an increased number of repetitions, and as far as possible a signaling requesting a confirmation message.

The advantage is a lower power consumption and a lower load on the wireless transmission link 05 , in particular a radio medium, if there is a good, undisturbed connection.

One Watching the radio or receiving beacon messages can before, during and after sending.

In One training can have several types of commands be sent with the remote control.

The Feedback within the meaning of the invention takes place in a variant embodiment only with some of these commands, especially with very critical commands, for example, only when a car is locked, but not at an opening, in a nurse call system only one Emergency call, but not for general signals requesting a non-critical Services.

In a variant, a warning of the user 04 in that a problem case can occur when sending a command, even before the triggering of a control command, for example by a status indication that there is a disturbed channel or a special test mode.

Specific Fields of application of the invention relate to a wireless interlock a vehicle, a wireless arming of an alarm system, and a wireless nurse call system where patients over have a wireless emergency button, for example to reduce the installation work for outside regular hospital room occupied beds, for patients on the way to examination and treatment rooms in Hospitals, for mobile patients or older Residents in a care facility and the like.

Advantages of the invention over the prior art are given in particular by:

• Improved protection in the event of a disturbed radio channel prior to non-execution of a remote control command;
• - a simple realization, since no confirmed two-way communication between the Remote control and a remotely controlled object is required;

An in 2 illustrated flowchart 20 shows a first embodiment of a method according to the invention, in which in the presence of a problem case, the command is not sent. In a first process step 21 the procedure is started, for example by switching on the remote control or by a timer, which starts the procedure in regular cycles. In a second process step 22 actuates a user 04 a button 02 to a desired, wireless to a device 06 to trigger a command to be transmitted. In a third process step 23 an observation of a wireless transmission link takes place 05 , In a fourth process step 24 a decision is made as to whether the result of the observation in the previous procedural step 23 to indicate a problem case or not. Is the result of the fourth process step 24 that no problem case or a good case is present, so the result of the observation in the third step 23 as uncritical to judge, so in a fifth step 25 the desired command is sent. Is the result of the fourth process step 24 that a problem case exists or might be present, so the result of the observation in the third step 23 as critical to judge, so in a sixth procedural step 26 For example, a feedback tactile, audible or visual to the user 04 signaling that this is made aware of a failure to transfer the command. In a seventh process step 27 the procedure is terminated.

Alternatively, the command could always be sent and the user 04 only additional feedback information will be given.

The flowchart 30 in 3 shows a second embodiment of a method according to the invention, in which, in the problem as before, a user feedback is done by the remote control. However, a command will always be sent. In the case of a problem this is done in a transmission mode 'critical', whereas otherwise it is transmitted in the transmission mode 'non-critical'. The transmission mode 'critical' is characterized for example by an increased transmission power and / or an increased number of repetitions and / or, if possible, by explicitly requesting an acknowledgment message.

Again, the process is again in a first step 31 started. In a second process step 32 will also be a button 02 Press a desired, wirelessly to a device 06 to trigger a command to be transmitted. In a third process step 33 an observation of a wireless transmission link takes place 05 , In a fourth process step 34 a decision is made as to whether the result of the observation in the previous procedural step 33 to indicate a problem case or not. Is the result of the fourth process step 34 that no problem case or a good case is present, so the result of the observation in the third step 33 as uncritical to judge, so in a fifth step 35 an already described transmission mode 'uncritical' activated and then the command in an eighth step 38 sent in send mode 'non-critical'. Is the result of the fourth process step 34 that a problem case exists or might be present, so the result of the observation in the third step 33 as critical to judge, so in a sixth procedural step 36 For example, a feedback tactile, audible or visual to the user 04 signaling that this is made aware of a possibly not carried out or successful transmission and / or execution of the command. In a seventh process step 37 Subsequently, a previously described transmission mode 'critical' is activated and then the command in an eighth step 38 sent in send mode 'critical'. In a ninth procedural step 39 the procedure is terminated.
