Description

[Technical Field]

[0001] The present invention relates to a non-contact switch control system, and more particularly to a non-contact switch control system having a function used for cleaning work. [Background technology]

[0002] Contactless products can avoid the risk of virus infection through contact, but they require cleaning between uses due to factors such as ash dust.

[0003] When cleaning crews clean current non-contact switches (e.g., floating touch switches), the need for cleaning often results in the non-contact switches being accidentally touched and activated unnecessarily frequently during the cleaning process. Summary of the Invention

[0004] To this end, the present invention provides a contactless switch control system. The contactless switch control system includes a group of switches, a memory unit, and a processing unit. The group of switches includes a plurality of contactless switches, and the plurality of contactless switches include one or more first contactless switches and one or more second contactless switches. The contactless switch control system of the present invention can have a first operating mode (standby mode) and a second operating mode (cleaning mode, invalidation mode). Furthermore, the contactless switch receives a detection signal from a detection object using a floating touch area and transmits the detection signal to the processing unit, which then executes a control program stored in the memory unit to change the state of the switch. The detection object may be an external device or an unspecified object. The processing unit can use one or more of the multiple non-contact switches as a first non-contact switch and one or more as a second non-contact switch, and when the first non-contact switch receives an identification signal in a first operating mode (standby mode), the non-contact switch control system enters a second operating mode (cleaning mode, disable mode), and the processing unit can disable the second non-contact switch in the second operating mode, for example, by sending a disable command, thereby causing the switch function of the non-contact switch designated as the second non-contact switch among the multiple non-contact switches to be lost, and preventing a cleaner from accidentally touching and activating the non-contact switch during cleaning work.

[0005] The present invention provides a non-contact switch control system comprising: a switch group including a first non-contact switch and a second non-contact switch for receiving a detection signal of a detection target; a memory unit for storing a control program; and a processing unit connected to the switch group and the memory unit for executing the control program and controlling the switch group based on the detection signal. The control program comprises the steps of: determining whether the first non-contact switch has received an identification signal in a first operating mode and obtaining a first determination result; and, if the first determination result is "yes," the non-contact switch control system entering a second operating mode and disabling the second non-contact switch.

[0006] In one embodiment of the present invention, the contactless switch control system further comprises a timing unit connected to the processing unit for counting a first time segment, and the control program further comprises the steps of: when the contactless switch control system enters the second operation mode, the timing unit starts counting the first time segment; and when the counting of the first time segment ends, the contactless switch control system returns to the first operation mode.

[0007] In one embodiment of the present invention, the group of switches of the non-contact switch control system comprises a receiving unit for receiving an identification signal including an external signal transmitted from an external device.

[0008] In one embodiment of the present invention, the switches of the non-contact switch control system include an illuminating unit and a receiving unit, and the identification signal includes a reflected signal of an internal signal, wherein the illuminating unit transmits the internal signal to the detection target, and the receiving unit receives the reflected signal of the internal signal.

[0009] In one embodiment of the present invention, the timing unit of the contactless switch control system is further used to count a second time segment, and the control program further includes the steps of: when the first contactless switch receives the identification signal, the timing unit starts counting the second time segment, determining whether the first contactless switch continues to receive the identification signal within the second time segment, and obtaining a second determination result; and when the second determination result is "yes," the contactless switch control system enters a second operating mode and disables the second contactless switch.

[0010] In one embodiment of the present invention, the contactless switch control system further includes a counting unit connected to the processing unit for counting a detection count, the counting unit being further used for counting a second time segment, and the control program further includes the steps of: when the first contactless switch receives the identification signal, the counting unit starts counting the second time segment, determining whether the detection count in the second time segment is equal to or greater than a detection count threshold, and obtaining a third determination result; and when the third determination result is "yes," the contactless switch control system enters a second operating mode and disables the second contactless switch.

[0011] In one embodiment of the present invention, the non-contact switch control system further comprises a prompt unit connected to the processing unit for providing an operation mode prompt.

[0012] In summary, the non-contact switch control system of the present invention can use one or more of the multiple non-contact switches as the first non-contact switch and one or more as the second non-contact switch. When the first non-contact switch receives an identification signal in a first operating mode (standby mode), the non-contact switch control system enters a second operating mode (cleaning mode, disabling mode). The processing unit can disable the second non-contact switch in the second operating mode, for example, by sending a disabling command. This disables the switch function of the non-contact switch designated as the second non-contact switch among the multiple non-contact switches, thereby preventing cleaning staff from accidentally touching and activating the non-contact switch while cleaning. The above-described structure of the present invention prevents cleaning staff from accidentally touching and activating the non-contact switch during cleaning work. For example, the present invention can be applied to an elevator system, where cleaning staff cannot accidentally touch and activate the non-contact switch of the present invention while cleaning. Therefore, when the present invention is applied to an elevator system, unnecessary elevator call operations can be reduced, resulting in technical effects such as power savings and shortened waiting times for users.

[0013] In order to make the above and other objects, features and advantages of the present invention more clearly understandable, the following detailed description will be given with reference to the accompanying drawings, in which: [Brief explanation of the drawings]

[Figure 7] FIG. 2 is a block diagram of a contactless switch control system provided by a further embodiment of the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0015] Referring to Figures 1 and 2, Figure 1 is a block diagram of a non-contact switch control system provided by an embodiment of the present invention, and Figure 2 is a block diagram of a non-contact switch provided by an embodiment of the present invention.

[0016] In this embodiment, the non-contact switch control system 1 of the present invention includes a switch group SWS, a processing unit PU, a memory unit SU, and a timing unit TU. The switch group SWS includes a plurality of non-contact switches NCSW, and the processing unit PU is connected to the plurality of non-contact switches NCSW, the memory unit SU, and the timing unit TU.

[0017] In this embodiment, the operation modes of the non-contact switch control system 1 of the present invention include a first operation mode (standby mode) and a second operation mode (cleaning mode, invalidation mode). The non-contact switch control system 1 can receive a detection signal of a detection target ST within the floating touch area using the non-contact switches NCSW and transmit the detection signal to the processing unit PU. The processing unit PU then executes a control program stored in the storage unit SU to change or determine the switch state of each non-contact switch NCSW. The detection target ST can be an external device ED or an unspecified object OB (for example, the detection target ST can be a wireless signal transmitting device, a remote control, a human body, a part of a human body, or another device or object capable of transmitting a detection signal. The detection signal of the detection target ST can be a wireless signal transmitted via a communication protocol, the capacitance value of the human body, infrared light, an ultrasonic reflection signal, etc.). The processing unit PU can use at least one of the multiple non-contact switches NCSW as a first non-contact switch (which may also be called a trigger switch), and can use one or more as second non-contact switches (i.e., non-contact switches NCSW that are disabled in the system). When the first non-contact switch receives an identification signal in a first operating mode (standby mode), the non-contact switch control system enters a second operating mode (cleaning mode, disable mode), and the processing unit can disable the second non-contact switch in the second operating mode, for example, by sending a disable command, and can cause the switch function of the non-contact switch designated as the second non-contact switch among the multiple non-contact switches to be lost.

[0018] To avoid any ambiguity in the definition of nouns, the following will first explain the specific nouns used in the embodiments of the present invention.

[0019] In the present invention, the first non-contact switch refers to a non-contact switch NCSW for triggering a second operation mode (cleaning mode, disable mode). In the non-contact switch control system 1, the first non-contact switch may be a non-contact switch NCSW designated or preset as a trigger switch. In other words, one or more first non-contact switches are selected from a plurality of non-contact switches NCSW in the switch group SWS, and each of the non-contact switches NCSW in the switch group SWS may be designated or preset as the first non-contact switch.

[0020] In the present invention, the second non-contact switch refers to a non-contact switch NCSW that is disabled in a second operating mode (cleaning mode, disable mode). That is, the second non-contact switch is selected from the plurality of non-contact switches NCSW in the switch group SWS, and there may be one or more second non-contact switches. Any one of the non-contact switches NCSW in the switch group SWS may be designated or preset as the second non-contact switch. In one embodiment, each non-contact switch NCSW in the switch group SWS may be designated or preset as both the first non-contact switch and the second non-contact switch at the same time.

[0021] In the present invention, "disabling" refers to the operation of causing a component to lose its original function within the system. For example, disabling the second non-contact switch refers to the operation of causing the processing unit PU to ignore signals from the second non-contact switch, or the operation of the processing unit PU sending a control signal to the second non-contact switch to temporarily ignore commands. In one embodiment, the processing unit PU sends a stop command to the irradiation unit EU of the second non-contact switch to stop transmitting wireless signals, thereby preventing the second non-contact switch from receiving reflected signals of the wireless signals (i.e., detection signals from the detection target ST). This disables the second non-contact switch NCSW2 and achieves the technical effect of preventing malfunction. Note that "disabling" refers to the operation of causing a component to lose its original function within the system (e.g., causing a switch to lose its trigger function), and the present invention is not limited in this respect.

[0022] In the present invention, the identification signal refers to a signal for triggering a second operation mode (cleaning mode, invalidation mode). For example, the identification signal may be an external signal (which may also be called a wireless signal) transmitted from the external device ED, or a reflected signal reflected by the detection object ST after the illuminator EU of the first non-contact switch transmits an internal signal to the detection object ST. In other words, the identification signal may be a reflected signal of the internal signal. The identification signal may include an external signal transmitted from the external device ED or a reflected signal of the internal signal.

[0023] Next, the detection module SM of the non-contact switch NCSW will be described below.

[0024] In one embodiment of the present invention, the non-contact switch NCSW includes a sensing module SM and a switch module SWM, and the sensing module SM may further include an illuminating unit EU and a receiving unit RU.

[0025] For example, the sensing module SM may be a capacitive sensing module. When the sensing module SM is a capacitive sensing module, the sensing target ST may be a human body, a part of a human body, or an object OB whose capacitance value sensed by the sensing module SM can be changed as desired. The capacitive sensing module can detect the capacitance value of the human body, and the processing unit PU can transmit a first control signal to control the switch module SWM based on the change in the capacitance value.

[0026] For example, the detection module SM may be an infrared light detection module. The detection module SM may include an irradiator EU and a receiver RU. When the detection module SM is an infrared light detection module, the detection target ST may be a human body, a part of a human body, or an object OB that reflects infrared light (i.e., a reflected signal of an internal signal) irradiated from the irradiator EU for irradiating infrared light. The receiver RU of the detection module SM can receive the infrared light irradiated by the irradiator EU and reflected by the object OB. The processing unit PU can transmit a control signal to control the switch module SWM based on the detection signal of the detection target (i.e., a reflected signal of an internal signal) received by the receiver RU. In one embodiment, the receiver RU of the detection module SM can receive a detection signal of the detection target ST. The detection signal includes an external signal transmitted from an external device ED. The external device ED includes a transmitter for transmitting an infrared light wireless signal.

[0027] For example, the sensing module SM may be an ultrasonic sensing module, and the sensing module SM may include an emitter EU and a receiver RU. When the sensing module SM is an ultrasonic sensing module, the sensing target ST may be a human body, a part of a human body, or an object OB that reflects the ultrasonic wireless signal (i.e., a reflected signal of an internal signal) transmitted from the emitter EU for transmitting the ultrasonic wireless signal. The receiver RU of the sensing module SM may receive the ultrasonic wireless signal emitted by the emitter EU and reflected by the object OB. The processing unit PU may transmit a control signal to control the switch module SWM based on the sensing signal (i.e., a reflected signal of the internal signal) of the sensing target received by the receiver RU. In one embodiment, the receiver RU of the sensing module SM may receive a sensing signal of the sensing target ST. The sensing signal includes an external signal transmitted from an external device ED. The external device ED includes a transmitter for transmitting the ultrasonic wireless signal.

[0028] In one embodiment, the internal signal and the external signal can use the same communication protocol, and the processing unit PU can distinguish between the internal signal and the external signal by transmitting different data values. For example, if the internal signal transmitted is 0x55, the external signal can be defined as 0x99, which can be used to distinguish between the internal signal and the external signal and control the switch state of the switch module SWM or trigger the non-contact switch control system 1 to enter the second operating mode.

[0029] Referring now to FIG. 3, in one embodiment, the non-contact switch NCSW is implemented as a switch of a floating touch display. FIG. 3 is a schematic diagram of a switch of a floating touch display provided by one embodiment of the present invention. The switch of the floating touch display includes a floating display module FDM and a floating touch module FTM. The floating display module FDM includes a microlens array MLA, an imaging plate IP, a flat lens Plate, a circuit board PCBA, a light-emitting diode LED, and a connector C. The switch of the floating touch display of this embodiment can receive a detection signal of a detection target ST in a floating touch area FTR by the floating touch module FTM (the floating touch module FTM includes a sensing module SM). The floating touch area can include a detection distance and a detection angle. The detection distance is the distance from the sensing surface of the sensing module SM to the detection target ST, and can vary, for example, within a range of 0 to 10 cm. The detection angle is the angle formed by contracting inward from any point on the outer edge of the detection surface of the detection module SM (e.g., 0 cm) to the detection failure point (i.e., the distance at which it no longer reacts to the detection target ST, e.g., 10 cm), and can vary, for example, within a range from 80 degrees to 45 degrees.

[0030] The above examples are merely illustrative embodiments of the non-contact switch NCSW of the present invention, and the present invention is not limited to the listed embodiments. Any non-contact switch NCSW can be used as the non-contact switch NCSW of the present invention as long as it can provide a floating touch area that receives a detection signal of a detection target and control the switch state of the switch module SWM through a processing unit PU.

[0031] Next, the switch module SWM of the non-contact switch NCSW will be described below.

[0032] In this embodiment, the switch module SWM of the non-contact switch NCSW of the present invention refers to a device used as a switch in a circuit. The switch module SWM has a switch state. The switch state refers to the state of the switch module SWM in the circuit. The switch state can include, for example, an open state and a short state. The processing unit PU can, for example, send a control signal to switch the switch state of the switch module SWM. The switch module SWM can be connected to another external circuit, and the processing unit PU can control the external circuit based on the switch state of the switch module SWM. For example, the switch module SWM can be a multi-stage change-over switch (which opens or shorts the circuit), a transistor switch (which controls the voltage or current to cause the transistor to operate in the cutoff region or saturation region; when the transistor operates in the cutoff region, the switch state is considered to be the open state of the present invention, and when the transistor operates in the saturation region, the switch state is considered to be the short state of the present invention), or a logic circuit. However, the present invention is not limited to these. Any device that can control an external circuit by switching the switch state can be used as the switch module SWM of the present invention.

[0033] The non-contact switch control system 1 of the present invention includes a timing unit TU. The timing unit TU is connected to the processing unit PU and is a device for calculating time segments. For example, the timing unit TU may be a timing device that repeatedly turns on and off using components such as a motor or a coil, and calculates time units (seconds, minutes, hours, etc.) by counting the number of times the contacts are opened or shorted. However, the present invention is not limited to these, and any device that can calculate time can be used as the timing unit TU of the present invention.

[0034] The non-contact switch control system 1 of the present invention includes a storage unit SU. The storage unit SU is connected to the processing unit PU and refers to a device for storing a control program. The control program includes the steps of: in a first operating mode, determining whether a first non-contact switch receives an identification signal and obtaining a first determination result; if the first determination result is "yes," the non-contact switch control system enters a second operating mode and disables the second non-contact switch; when the non-contact switch control system enters the second operating mode, the timing unit starts counting a first time segment; when the counting of the first time segment ends, the non-contact switch control system returns to the first operating mode; and when the first non-contact switch receives the identification signal, the timing unit starts counting a second time segment and disables the first non-contact switch. The method further comprises determining whether the first non-contact switch continues to receive the identification signal within a second time segment and obtaining a second determination result; if the second determination result is "yes," the contactless switch control system enters a second operating mode and disables the second non-contact switch; and, when the first non-contact switch receives the identification signal, the timing unit starts counting the second time segment, determining whether the detection count is equal to or greater than the detection count threshold within the second time segment and obtaining a third determination result; if the third determination result is "yes," the contactless switch control system enters the second operating mode and disables the second non-contact switch. The processing unit PU is further used to execute the control program. For example, the storage unit SU may be a non-volatile memory, a memory card, a register, or other device with similar functionality. The listed types of storage devices are merely examples, and the present invention is not limited thereto. Any storage device with similar functionality may be used as the storage unit SU of the present invention.

[0035] The non-contact switch control system 1 of the present invention includes a processing unit PU. The processing unit PU is used as a processing core of a device connected to the switch group SWS, the memory unit SU, and the timing unit TU, and is configured to execute a control program stored in the memory unit SU and control the state of the switches in the switch module SWM. For example, the processing unit PU may be a one-chip microcomputer (MCU, Microcontroller Unit), a central processing unit (CPU), or other device with similar functionality. The listed types of processing units are merely examples, and the present invention is not limited thereto. Any device capable of executing a control program stored in the memory unit SU and controlling the state of the switches in the switch module SWM can be used as the processing unit PU of the present invention.

[0036] Reference is now made to FIG. 4, which is a flow chart provided by one embodiment of the present invention.

[0037] In this embodiment, the processing unit PU can execute a control program and cause the non-contact switch control system 1 to perform the following steps: Step S100: Start the process, then proceed to step S101. Step S101: The non-contact switch control system 1 enters a first operation mode (i.e., enters a standby mode), then proceed to step S103. Step S103: Determine whether the first non-contact switch has received an identification signal and obtain a first determination result ("Yes" or "No"). If the first determination result is "No", return to step S101 (i.e., return to the standby mode and determine whether the first non-contact switch has received an identification signal by polling). If the first determination result is "Yes", proceed to step S105. Step S105: If the first determination result is "Yes", the non-contact switch control system 1 enters a second operation mode (i.e., enters a cleaning mode or a disabling mode), then proceed to step S107. Step S107: The timing unit starts counting the first time segment. Next, proceed to step S109. Step S109: Disable the second non-contact switch and proceed to step S111. Step S111: When the counting of the first time segment is completed, the non-contact switch control system returns to the first operating mode (i.e., the non-contact switch control system 1 enters the second operating mode, starts counting a preset time, and returns to the standby mode after the preset time has elapsed).

[0038] Referring now to FIG. 5, FIG. 5 is a block diagram of a non-contact switch control system 1' provided by another embodiment of the present invention.

[0039] The present invention provides multiple embodiments. In each embodiment of the present invention, the same reference numerals are used to indicate that the function of the component or device is the same as in other embodiments. Therefore, in each embodiment of the present invention, the same functions will not be described repeatedly, and only the differences from other embodiments will be described. Furthermore, the matters and steps mentioned in each embodiment can be rearranged and combined as long as they are not overlapped, and can be applied to each embodiment. The present invention is not limited to the listed embodiments.

[0040] In this embodiment, the non-contact switch control system 1' of the present invention includes a switch group SWS, a processing unit PU, a memory unit SU, a timing unit TU, and a counting unit CU. The switch group SWS includes a plurality of non-contact switches NCSW, and the processing unit PU is connected to the plurality of non-contact switches NCSW, the memory unit SU, the timing unit TU, and the counting unit CU.

[0041] In this embodiment, the non-contact switch control system 1' of the present invention further includes a counting unit CU, which is connected to the processing unit PU and counts the detection count of the identification signal. The present invention uses the counting unit CU to count the detection count of the identification signal. For example, in this embodiment, a user can manually trigger the first non-contact switch multiple times. When the detection count of the counting unit CU is equal to or greater than the detection count threshold, the non-contact switch control system 1' can transition to the second operating mode.

[0042] Reference is now made to FIG. 6, which is a flow chart provided by another embodiment of the present invention.

[0043] In this embodiment, the processing unit PU can execute a control program and cause the non-contact switch control system 1' to perform the following steps: Step S200: Start of the process, then proceed to step S201. Step S201: The non-contact switch control system 1' enters a first operating mode (i.e., enters a standby mode), then proceed to step S203. Step S203: Determine whether the first non-contact switch has received an identification signal, and obtain a first determination result ("yes" or "no"). If the first determination result is "no", return to step S201 (i.e., return to standby mode, and determine whether the first non-contact switch has received an identification signal by polling). If the first determination result is "yes", proceed to step S204. Step S204: The timing unit starts counting the second time segment, and then proceeds to step S2041 or S2042 (either step S2041 or step S2042 may be included, depending on the user's needs; alternatively, both steps S2041 and S2042 may be included simultaneously). Step S2041: Determine whether the first contactless switch continues to receive an identification signal (e.g., the hand continues to be placed on the floating touch area of ​​the detection module SM) during the second time segment, and obtain a second determination result. If the second determination result is "No", proceed to step S201; if the second determination result is "Yes", proceed to step S205. Step S2042: Determine whether the detection count is greater than or equal to the detection count threshold during the second time segment, and obtain a third determination result. If the third determination result is "No", proceed to step S201; if the third determination result is "Yes", proceed to step S205. Step S205: The non-contact switch control system 1' enters the second operation mode (i.e., enters the cleaning mode, the disabling mode), and then proceeds to step S207. Step S207: The timing unit starts counting the first time segment, and then proceeds to step S209. Step S209: Disable the second non-contact switch and proceeds to step S211. Step S211: When the counting of the first time segment is completed, the non-contact switch control system 1' enters the first operation mode.

[0044] Referring now to FIG. 7, FIG. 7 is a block diagram of a non-contact switch control system 1'' provided by one embodiment of the present invention.

[0045] In this embodiment, the non-contact switch control system 1'' of the present invention further includes a prompt unit PSU. The prompt unit PSU is connected to the processing unit PU and is used to provide prompts for the operating modes. The prompt unit PSU may be included in the non-contact switch NCSW or may be an independent device. The prompt unit PSU may be a device such as a buzzer, a light-emitting diode, or a liquid crystal display. When the system enters different operating modes, the prompt unit PSU may provide different prompt information, or may provide prompt information only in specific operating modes. For example, when a cleaning staff member triggers the control switch to enter the system into the first operating mode, the prompt unit PSU may send prompt information (such as voice information, text information, or color information) by generating a sound, lighting a different colored light-emitting diode, displaying text, etc., to notify the cleaning staff that the system is currently in cleaning mode and that the designated non-contact switch NCSW is disabled. After the first operating mode ends (i.e., when the system enters standby mode), the prompt unit PSU stops sending prompt information. In one embodiment, the prompt unit PSU may send different prompt information for different operating modes. For example, the non-contact switch control system 1'' may be provided with a plurality of light-emitting diodes of different colors, and light-emitting diodes of different colors may be lit in the first operating mode, the second operating mode, and the standby mode, respectively, to notify the cleaning personnel with the light-emitting diodes of different colors, thereby quickly informing them of the current operating mode of the system and achieving the technical effect of quickly checking the operating mode of the system.

[0046] In summary, the non-contact switch control system of the present invention can use one or more of the multiple non-contact switches as the first non-contact switch and one or more as the second non-contact switch. When the first non-contact switch receives an identification signal in a first operating mode (standby mode), the non-contact switch control system enters a second operating mode (cleaning mode, disabling mode). The processing unit can disable the second non-contact switch in the second operating mode, for example, by sending a disabling command. This disables the switch function of the non-contact switch designated as the second non-contact switch among the multiple non-contact switches, thereby preventing cleaning staff from accidentally touching and activating the non-contact switch while cleaning. The above-described structure of the present invention prevents cleaning staff from accidentally touching and activating the non-contact switch during cleaning work. For example, the present invention can be applied to an elevator system, where cleaning staff cannot accidentally touch and activate the non-contact switch of the present invention while cleaning. Therefore, when the present invention is applied to an elevator system, unnecessary elevator call operations can be reduced, resulting in technical effects such as power savings and shortened waiting times for users.

Those skilled in the art may make some modifications without departing from the spirit and scope of the present invention.
