Abstract
The invention relates to an input unit and a method for the input unit, the control unit of the input unit comprising a transmitter unit having one or more transmitting elements and a receiving unit having one or more receiving elements wherein the transmitter and receiver elements are adjusted such that their respective propagation paths pass close to the control element between the corresponding transmitter and receiver elements.
Description
The invention relates to an example of the formation of an input unit.
The control signal may be preset to a motorized drive unit or device component, using a joystick, which may also be referred to as input means.
For example, if the motorized drive unit of the medical device is initiated via such an input means, the input means is unlocked before use so that the drive unit is not inadvertently activated. However, the unlocking of the input means has the disadvantage that unintentional control signals can also be initiated in this operating state by the input means. Therefore, after the unlocking of the input means, the control signal by the input means can be formed on the input field of the input means by touching the input means or by inadvertently depressing the button. Moving device parts also have a risk of collision with other objects. In addition to the input means, a so-called dead man's switch is arranged in the operating unit or the apparatus to be controlled in order to prevent possible collision, thereby terminating the movement in the apparatus in advance.
An object of the present invention is to propose a further input unit for controlling the device.
The above problem is solved by the features set forth in
An input unit for outputting a control signal for a device unit is provided with input means. The input means has a control element for detecting a control signal. The control element is coupled to a transmitter unit having one or more transmitting elements and a receiver unit having one or more receiving elements. The transmitting element and the receiving element are adjusted so that the respective propagation paths pass between the corresponding transmitting element and the receiving element and close to the control element.
The input unit includes at least one checking unit for checking the control signal input by the input means. When the input means is used as intended, the first checking unit checks the control signal using a temporary release signal.
When the transmission path between the transmitting element and the receiving element, which is proceeding in the control element, is interrupted by the hand of the operator wrapping the control element of the input means, the control signal applied by the first checking unit is temporarily released .
Control signals or control signals are temporarily released if at least one of the optical transmission paths guided directly along the surface of the cylindrical input means is interrupted by the operator as intended. The control signal continues to be transmitted to the device unit only when the preceding control process has not occurred with respect to the device unit to be controlled by the dependent inspection units.
The present invention has the advantage that unintended initiation of the control signal is not made.
The present invention has the advantage that the deadman switch is not required to be actuated separately by the operator by engaging the deadman switch into the input unit, since the initiation of the deadman switch is not effected, The deadman switch is initiated and no additional control process of the device unit is performed.
The present invention has the advantage that the control signal is output to the device unit to be controlled only when the input means and the collision-free motion are manipulated as intended.
The present invention has the advantage that unintentional movement of a device unit is not achieved through evaluation of a control signal and a seonsor signal using a plurality of channels.

In the case of this input unit, it is checked whether the input means has been used as intended and the control signal is released and implemented only when the preceding device internal signaling of the device to be controlled is not made.
1 is a schematic diagram showing a basic circuit diagram of an input unit EEH for a device unit GE to be controlled. The input unit EEH has, among other things, a pre-processing unit VE comprising an input means JS and an evaluation unit AS. The evaluation unit AS may be referred to as a first inspection unit, and the preprocessing unit VE may also be referred to as a second inspection unit. The input means JS has one or more sensors and / or a sensor field (SF). The preprocessing unit VE can be used for, for example, electrical connection of a sensor SF, grouping by inspection of sensor data, integration of a sensor pair and data output by the sensor (level conversion of data) is performed. The logical operation of the sensor data selected using the evaluation unit AS is performed. Further, in the evaluation unit AS, for example, operational settings such as the deflection intensity and direction of the joy stick, and a pressed release button or an operation button (AT) are checked. The evaluation unit AS may, in a further alternative embodiment, provide self-test logic for checking the switch state and the validity of the bias value, for example when the joy stick is initiated . The system control unit (SSE) continues to receive the pre-processed sensor signals and control signals of the evaluation unit AS and the final decision on drive element control is taken from the device parts. The system control unit SSE is assigned to the device unit GE in this figure. The system control unit SSE uses additional data, such as, for example, the operating procedure of the device GE, the system state. The system control unit SSE, which is also referred to as a third inspection unit, evaluates the applied operating data using the status information of the unit to be controlled, and if the preceding signaling is not performed, Lt; / RTI > device device. The input unit EEH is connected to the device unit GE via a sufficiently formed transmission path UES. The transmission path (UES) may be formed as a bi-directional transmission path (UES), each channel-connected and / or channel-free.
In the evaluation unit AS, in addition to the validity check, a safety check is also performed. The control signal is temporarily released only when the control command or control signal set by the joy stick JS has been evaluated to be valid through, for example, threshold evaluation. In the evaluation unit AS, among other things, the control signal pre-set by the input means JS is checked for validity with respect to, for example, its own height and start. The joy stick JS is formed to have at least one sensor field SF. As the sensor, for example, an infrared sensor or a passive infrared sensor may be used. In addition to the sensor surface, it is also possible to measure the electroconductivity of the envelope, the pulse recognition, the sensors for measuring ultrasonic waves and the capacitive variation when the joy stick is wrapped And a measurement of the body-impedance signal can be made. The control signal output by the input means JS is confirmed by a temporary release signal when the input means JS is operated as intended.
The input means JS is connected to a system control unit SSE via a preprocessing unit VE comprising an evaluation unit AS. The control signal inspection is also performed in the preprocessing unit VE and in the system control unit SSE.
The input means JS comprises a cylindrical element in this schematic view. The cylindrical element is wrapped by the operator's hand during the control process of the device unit GE. As the joy stick JS is tilted, for example, the moving direction and / or the moving speed for the device unit to be controlled is preset. The device unit to be controlled using the operation element and / or the release button (AT) described in Fig. 2 is selected and the values set by the joy stick can be continuously transmitted to the system control unit (SSE) or the device unit.
Fig. 2 shows an example of the formation of the input means JS. The cylindrical element of the input means JS was cast in the form of a shaft. A sensor and / or sensor field (SF) for detecting intentional manipulation of the input means for more accurate detection is located on and / or within the shaft surface. The input means JS may use one or more additional select buttons integrated into the device unit GE, for example to terminate or to initiate such functions as radiation activation or to switch the movement function. . The first end of the cylindrical input means JS is surrounded by a lower restricting portion UB and the second end is surrounded by an upper restricting portion OB. The cylindrical shaft SA between the lower limiting portion UB and the upper limiting portion OB was cast in such a manner that the shaft could be wrapped by the operator's hand in terms of its height and diameter. Above the upper limit portion OB, one or a plurality of operating elements or release buttons (AT) for selecting the function of the device unit assigned to the apparatus may be arranged according to the diameter of the cylindrical formed shaft SA . The release button may be provided, for example, to trigger an X-ray. Is surrounded by a protective element (MSW), individually or collectively, to prevent inadvertent opening of the operating button or release button (AT). To this end, the protective element has been molded such that individual or overall buttons are surrounded by elements in the form of ridges. In this case, the heights of the ridge-shaped elements are formed so as to exceed the height of the release button, respectively. The two restraints are slightly larger in diameter than the diameter of the shaft SA formed in a cylindrical shape. In the lower limiting portion UB, the transmitting element SE of the transmitting unit SEH is disposed in the direction of the upper limiting portion. A reception unit (EFE) is coupled to the upper limit unit (OB) so as to correspond to a transmission unit (SEH) of the lower limit unit (UB). 3, the transmitting unit SEH is cast with one or more transmitting elements SE1, ..., SEm, and the receiving unit EFE has one or more receiving elements EE1, ..., EEm). The aperture angle of the transmitting means SEn has been adjusted for one or more receiving elements EEn. The adjustment process may be accomplished, for example, by means of a laser diode, by means of additional optical auxiliary means such as a lens, a polarizing filter or a frequency filter for a different color . The transmitting elements SE1, ..., SEm are circulating and can be switched-on and switched off. In this case, each transmitting element SEn always emits light continuously for only a few milliseconds and the light is transmitted to the transmitting element SE1, ..., which is arranged in the joy stick JS in a specific pattern. ., SEm). The transmitting element SEn and the receiving element EEn can be continuously controlled or read out, respectively, using control logic arranged in the shaft, for example. The selection of each inspection path IL may be made arbitrarily. The transmitting element SEn can also operate through differently modulated light wavelengths to facilitate discrimination. Wrapping of the shaft with the operator's hand can also cause the interruption of the confronting transmission path.
One or more transmitting elements SE1, ..., SEm of the transmitting unit SEH are assigned to one or more receiving elements EE1, ..., EEm, respectively. In the illustrated variant embodiment, the receiving unit (EFE) and the transmitting unit (SEH) are connected via one or more infrared connections. The optical connection / transfer path IL between the two units is guided directly over, for example, the shaft SA. The transmission path IL may also be referred to as a light barrier. The function of the deadman button can be checked by the light barrier evaluation process described above in the shaft / control element SA of the joy stick JS.
The input means JS is connected to the preprocessing unit VE via a coupling element KE. The input means JS can be supported by a plurality of axes via the coupling element KE. Therefore, for example, the moving direction and / or the moving speed of the device component can be determined according to the deviation of the input means JS. The deflection of the input means JS is evaluated using a sensor, for example a tilt detector, in the input means JS and / or the coupling unit KE.
As described above and as shown in the figure, the control signal is detected only when a temporary release signal is applied. The temporary release signal is generated by the evaluation unit AS when a prescribed interruption of the infrared connection path is made. At this time, the control signal is continuously transmitted to the system control unit (SSE) of the device unit GE via the connection logic in the preprocessing unit VE according to an alternative embodiment. In an alternative embodiment with a select button, the control signal continues to be transmitted to the selected device part of the device unit GE after the inspection in the system control unit SSE. Temporary release signals can be identified through additional sensor-based scans.
A sensor surface, which is coupled to / on the shaft SA of the input means JS and which has a plurality of parts consisting, for example, of diagonally opposed two sensor surfaces, is wrapped by the operator's hand, And the control signal can continue to be passed to control the device part after the inspection in the system control unit.
In a further variant embodiment the preprocessing unit VE is designed such that the control signal initiated by the joystick (JS) is released only when a number of transmit-receive paths are simultaneously interrupted by the hand wrapping the shaft.
In a further variant embodiment, the control signal is only released when additional clear signaling is made by the additional sensor to form the appropriate condition of the input means JS. As a further feature, capacitive or inductive measurements measurable by the operator ' s hand can be detected and / or pulse measurements and thermal measurements or identification as output by the operator.
The components of the shaft SA and the mechanical shielding wall MSW are arranged in a light emitting element LE of a plurality of colors emitted in a plurality of colors in order to visually indicate the respective inspection process of the control signal to the operator in a further production example, . ≪ / RTI > Therefore, if the number of predetermined transmission paths is not interrupted without being wrapped by the hand wrapping the shaft as the shaft SA of the input means JS intends, for example, the signal of the light emitting elements LE flashing in red The LED light emitting elements LE indicate the interruption of the provided control signal. For example, if a prescribed interruption of the infrared signal, such as the interruption of the transmission path IL, arranged in the diagonally shafts SA is made, the light emitting elements LE for indicating the respective operating states, And the operator can transmit a control signal to the device unit, for example, by operating a release button of one of the release buttons (AT). After the system internal inspection process by the system control unit (SSE), a continuous green signal is provided. In the system control unit (SSE), it is checked whether the preceding signaling takes place in terms of the device unit (GE). The system control unit (SSE) is designed such that the release of the signal is continuously checked. The release of the signal is retracted once the preceding signaling occurs.
As shown in Fig. 3, the transmitting elements SE1, ..., SEn of the transmitting unit SEH are formed of infrared diodes. The infrared diodes are arranged in the form of a ring around the shaft SA, for example, in a lower limit UB. For example, the infrared diodes of the transmission unit SEH may be disposed at intervals of 45 degrees around the cylindrical shaft SA. In this modified embodiment, the infrared diodes are formed to have a limited radiation angle. This fact has the advantage that in this embodiment scattering radiation is prevented by the transmitting unit (SEH). Instead of being composed of infrared diodes, for example, a laser diode having a reduced radiation power can be used as the transmitting elements SE1, ..., SEn.
In a further exemplary embodiment, the receiving element EEn or the receiving unit EFE is arranged as a whole in the upper part OB of the shaft SA and is directed toward the transmitting element, respectively. To protect the transmitted signals, the receiving unit (EFE) may be surrounded by a scattered light protection ring, thereby reducing the risk of interference with extraneous light. The control signal initiated by the movement of the joy stick JS can be detected only when the operator's hand surrounds the input means JS and one or more of the transmission paths IL sent out from the transmission unit SEH are stopped And released by the dependent inspection unit.
In a further embodiment, in order to be able to eliminate unintentional interference and thereby prevent interference with other infrared sources, such as, for example, an optical tracking system, the transmission unit SEH) can be modulated by an infrared signal of a prescribed frequency.
A flow chart is shown in Fig. The flowchart is subdivided into a first module to a fifth module.
In the first module M1, the operation of the user at the input means JS and the detected sensor signal are received. In the second module, the control signal and the sensor signal are analyzed not only in the preprocessing unit VE but also in the evaluation unit AS. When control of the device unit GE is effected, visible signaling to the operator is initiated by the light emitting element LE provided for this signaling. A desired signal or a control signal by the input means JS and a temporary release signal for the predetermined signal or control signal are continuously transmitted to the system control unit SSE at the outlet of the second module M2 . The delivery process is included in the third module M3. In the fourth module M4, the system control unit SSE checks whether the preceding control signal, for example in the side of the device unit, should be processed or whether the device unit is provided directly without such a process. This preceding control signal may be, for example, an emergency stop signaling, an error message, which is temporarily applied in the operational aspect, or it may be an already entered end position in the movement process. In the fifth module M5, possible visualizability for the operator is reproduced, so that the operation command is executed, that is, for example, the intended motion is actually performed by the device unit GE. A temporary release signal is released and correspondingly signaled to the operator via the light emitting element LE. The green flickering signaling informing the operator of the admission of a temporary release signal is converted into a permanently applied green optical signal. In this case, the operator can perform the control in the device unit as intended by operating the release button (AT) again, for example. It is also conceivable that the control signal continues to be transmitted automatically. The fourth module (M4) and the fifth module (M5) are circulated while the valid signal is applied from the third module (M3).
In the following, the functions of the submodules coupled in the first to fifth modules M1, ..., M5 and the interaction of the submodules are respectively described.

The provision of a temporary release signal, denoted by submodule M2.4, is indicated by a flashing green signal by the emitting means. If the temporary release signal is omitted, the situation is indicated by the red light emitting element LE (submodule M2.5).
M3.1: If a provisional release signal is provided, the control signal and the temporary release signal are delivered to the system control unit (SSE) either on a single channel or on a cyclic basis over a number of channels.

The blinking green signaling is terminated and a permanent green signaling indicates the implementation or implementation of the control signal set to the operator. The state information for controlling the light emitting means LE is transmitted to the input unit EEH through a reverse channel.
M5.4, M5.5, M5.6: If a fault is present, a temporary release signal is blocked (submodule M5.4). The optical signaling by the flashing light emitting means LE is changed in some cases. This situation appears to the operator via permanent red signaling (sub-module M5.5) and control signals or manipulation commands are rejected (sub-module 5.6).
