Description

Technical Field

[0001] This invention relates to the field of human-computer interaction technology, and in particular to an interference-resistant human-computer interaction method. Background Technology

[0002] With technological advancements and the convenience of modern life, people have placed greater demands on quality of life and electronic devices, giving rise to a variety of intelligent devices that meet market needs. Among these, various control panels are an important type of clamp-on intelligent device.

[0003] A sense of ritual in life, and smart devices can add a sense of ritual, bringing a sense of technology and sophistication. Traditional control panels can only control various devices through an LCD screen, but when they are turned on, they usually only turn on the lights and there is no other operation. The sense of technology relies on the control panel to control the devices, such as controlling the color of the lights, the curtains, etc. The panel itself does not change much except for the backlight inside the panel, which is relatively simple.

[0004] With the improvement of equipment, new equipment has also emerged to meet market demands.

[0005] For example, Chinese patent application CN202220342957.4, published on August 2, 2022, discloses an intelligent control panel with a lifting knob, comprising: a front shell assembly with a liquid crystal knob hole and four guide shafts surrounding the liquid crystal knob hole at its rear end; a knob assembly sleeved on the four guide shafts, with its front end passing through the liquid crystal knob hole; a transmission assembly located at the ends of the four guide shafts, with its power output end connected to the knob assembly; a rear shell detachably connected to the rear end of the front shell assembly and covering the knob assembly and the transmission assembly; a wall-mounting assembly detachably connected to the rear end of the front shell assembly; and a power supply box located at the rear end of the wall-mounting assembly and detachably connected to the front shell assembly.

[0006] While this intelligent control panel improves the scientific human-computer interaction functionality and ease of disassembly and assembly of the adjustable knob, the motor requires manual operation, resulting in a lack of technological sophistication. When operating it, people need to adjust the knob's position and wait for it to extend before they can operate it. This waiting time can feel awkward, and having to touch the knob to extend it every time they enter the house can be frustrating, causing inconvenience and trouble.

[0007] Based on this, the present invention designs an interference-resistant human-computer interaction method to solve the above problems. Summary of the Invention

[0008] The purpose of this invention is to provide an interference-free human-computer interaction method that allows the control panel knobs to automatically extend when a person approaches, and to be visible when the person can touch them, making it more intelligent and providing a higher level of technological experience. Furthermore, this method avoids interference from motor operation on the sensors, shielding the frequency band interference caused by motor operation, and enabling the panel's extension and retraction function to operate effectively and be conveniently controlled.

[0009] The present invention is implemented as follows: an interference-resistant human-computer interaction method, which requires providing a human-computer interaction device, the device including: a telescopic device, a sensor, a display screen, a controller, and a housing; the telescopic device, sensor, display screen, and controller are all installed inside the housing, a limit switch is provided at each end of the travel of the telescopic device, the sensor, the telescopic device, and the two limit switches are all connected to the controller, the display screen is installed on the telescopic device, and the display screen is installed inside the housing so that it can extend or retract through the telescopic device;

[0010] The method includes the following steps:

[0011] Step S1: Both the controller and the sensor are in a normally active state. The sensor continuously monitors the external environment of the housing. The controller determines whether the telescopic device is in a retracted state or an extended state.

[0012] Step S2: When the telescopic device is in the retracted state and an object is detected within the monitoring range, proceed to step S3;

[0013] When the telescopic device is in the retracted state and no object is detected within the monitoring range, the sensor remains in the activated state and does not operate.

[0014] When the telescopic device is in the extended state and an object is detected within the monitoring range, return to step S1;

[0015] When the telescopic device is in the extended state and no object is detected within the monitoring range, proceed to step S4;

[0016] Step S3: The sensor sends a confirmation signal to the controller. After receiving the confirmation signal from the sensor, the controller controls the telescopic device to move outward. The telescopic device moves outward until it abuts against the limit switch at the outer end. The display screen extends out of the housing. The controller controls the telescopic device to stop and returns to step S1.

[0017] Step S4: The sensor sends a negative signal to the controller. After receiving the negative signal from the sensor, the controller starts the telescopic device to move inward. At the same time, the controller does not process the signal sent by the sensor. The controller controls the telescopic device to move in the opposite direction and retract until it abuts against the limit switch at the inner end. The display screen retracts into the housing. The controller controls the telescopic device to close. After a delay of t1, the controller restarts processing the signal sent by the sensor and returns to step S1.

[0018] Furthermore, the telescopic device is a linear stepper motor, and the time taken for the telescopic device to move from the inner end to the outer end or from the outer end to the inner end does not exceed 3 seconds.

[0019] Furthermore, the sensor is a microwave sensor, and the monitoring range of the sensor is 0.5 to 1 meter.

[0020] Furthermore, the display screen is a liquid crystal panel.

[0021] Furthermore, the initial state of the telescopic device is retracted into the housing. When the telescopic device abuts against the limit switch at the inner end, the controller determines that the telescopic device is in the retracted state. When the telescopic device abuts against the limit switch at the outer end, the controller determines that the telescopic device is in the extended state.

[0022] Furthermore, the time t1 is 1 second.

[0023] The beneficial effects of the present invention are: 1. The present invention adds a sensor, and the added sensor is a microwave sensor, which can more accurately sense the human body and the sensing range is accurate. It can sense people within a suitable operating range, and the display screen can be extended in advance. The pre-operation facilitates people's operation, and the sensing range is appropriate, so that people nearby can see the process of the display screen extending, allowing users to intuitively experience the technological feel of the smart device.

[0024] 2. The device has a suitable sensing range, avoiding misjudgment of people at a distance. Furthermore, the telescopic device and the sensor do not operate simultaneously but intermittently. This control method effectively avoids mutual interference between devices. Moreover, when each device is operating, it is not in standby mode but completely turned off, effectively avoiding mutual interference and resulting in higher sensing accuracy.

[0028] The attached diagram lists the components represented by each number as follows:

[0029] 1-Telescopic device, 11-Limit switch, 2-Sensor, 3-Controller, 4-Display screen, 41-Housing. Detailed Implementation

[0030] Please see Figures 1 to 2 As shown, the present invention provides a technical solution: an anti-interference human-computer interaction method, comprising:

[0031] The method requires providing a human-computer interaction device, which includes: a telescopic device 1, a sensor 2, a display screen 4, a controller 3, and a housing 41; the telescopic device 1, the sensor 2, the display screen 4, and the controller 3 are all installed inside the housing 41; a limit switch 11 is provided at each end of the travel of the telescopic device 1; the sensor 2, the telescopic device 1, and the two limit switches 11 are all connected to the controller 3; the display screen 4 is installed on the telescopic device 1; and the display screen 4 is installed inside the housing 41 so that it can extend or retract through the telescopic device 1.

[0032] The method includes the following steps:

[0033] Step S1: Both the controller 3 and the sensor 2 are in a normally active state. The sensor 2 continuously monitors the external environment of the housing 41. The controller 3 determines whether the telescopic device 1 is in a retracted state or an extended state.

[0034] Step S2: When the telescopic device 1 is in the retracted state and an object is detected within the monitoring range, proceed to step S3.

[0035] When the telescopic device 1 is in the retracted state and no object is detected within the monitoring range, the sensor 2 remains in the activated state and does not operate.

[0036] When the telescopic device 1 is in the extended state and detects an object within the monitoring range, return to step S1;

[0037] When the telescopic device 1 is in the extended state and no object is detected within the monitoring range, proceed to step S4;

[0038] Step S3: The sensor 2 sends a confirmation signal to the controller 3. After receiving the confirmation signal from the sensor 2, the controller 3 controls the telescopic device 1 to move outward. The telescopic device 1 moves outward until it abuts against the limit switch 11 at the outer end. The display screen 4 extends out of the housing 41. The controller 3 controls the telescopic device 1 to stop and returns to step S1.

[0039] Step S4: Sensor 2 sends a negative signal to controller 3. Upon receiving the negative signal from sensor 2, controller 3 initiates the inward translation of telescopic device 1. Simultaneously, controller 3 begins to ignore the signal emitted by sensor 2. Controller 3 controls telescopic device 1 to move in the opposite direction and retract until it abuts against the limit switch 11 at the inner end. The display screen 4 retracts into the housing 41. Controller 3 then controls telescopic device 1 to close, and after a delay of t1, controller 3 restarts processing the signal emitted by sensor 2 and returns to step S1. This method allows the control panel knob to automatically extend when a person approaches, and the extension is visible when the person can touch it, making it more intelligent and providing a higher level of technological experience. Furthermore, this method avoids interference from motor operation on the sensor, shielding the frequency band interference caused by motor operation, ensuring effective operation and convenient control of the panel's telescopic function.

[0040] The telescopic device 1 is a linear stepper motor. The telescopic device 1 takes no more than 3 seconds to move from the inner end to the outer end or from the outer end to the inner end. By controlling the telescopic time, the telescopic stroke of the display screen 4 can be experienced, giving people a sense of technology. At the same time, it can use less stroke time to avoid waiting too long when operating the button.

[0041] Sensor 2 is a microwave sensor with a monitoring range of 0.5 to 1 meter, which reduces the chance of misjudgment and does not have too long a telescopic delay, so as not to affect operation.

[0042] Display screen 4 is an LCD panel, which has a simple structure, is easy to operate, and enhances the smart experience;

[0043] The initial state of the telescopic device 1 is retracted into the housing 41. When the telescopic device 1 abuts against the limit switch 11 at the inner end, the controller 3 determines that the telescopic device 1 is in the retracted state. When the telescopic device 1 abuts against the limit switch 11 at the outer end, the controller 3 determines that the telescopic device 1 is in the extended state. This avoids errors in the starting position of the equipment due to other external factors and reduces the probability of failure caused by external factors.

[0044] The time t1 is 1 second, which is simple to operate and matches the running time of the telescopic device 1, reducing waiting time and avoiding mutual interference when starting at the same time.

[0045] In a specific embodiment of the present invention:

[0046] This invention provides an anti-interference human-computer interaction method. The technical problems encountered by this invention are: 1. Existing control panels only have backlighting, and some cannot even highlight text, resulting in simple backlight panel structures, poor visual effects, and limited functionality, making them no different from conventional displays; 2. There are also a few more intelligent operation buttons that can light up when touched, providing a visual experience and making it easier for people to view the markings on the panel, but their structures are simple; 3. There are now retractable panel buttons that can be extended or retracted under human control, but the operation is cumbersome, and users need to wait for the buttons to extend, making them impractical.

[0047] The technical problem solved by the present invention is that by using sensor 2 to monitor people who are approaching in advance and controlling the telescopic device 1 to start, the display screen 4 can be automatically extended for people to operate when they are approaching without waiting time, which is convenient to use.

[0048] The technical effects achieved are as follows: 1. The present invention adds a sensor 2, which is a microwave sensor, which can more accurately sense the human body and has a precise sensing range. It can sense people within a suitable operating range, and the display screen 4 is extended in advance. This pre-operation facilitates operation and the appropriate sensing range allows people nearby to see the process of the display screen 4 extending, allowing users to intuitively experience the technological feel of the smart device.

[0049] 2. This device avoids misjudging people at a greater distance by setting an appropriate sensing range for sensor 2 or selecting a sensor 2 with an appropriate sensing range. Furthermore, the telescopic device 1 and sensor 2 of this device do not operate simultaneously but intermittently. This control method effectively avoids mutual interference between devices. When the device is running, it is not in a standby state but is completely turned off, which effectively avoids mutual interference and results in higher sensing accuracy.

[0050] The technical solution in this invention is to solve the above problems, and the overall idea is as follows:

[0051] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0052] In manufacturing this invention, a housing 41 needs to be made. The telescopic device 1, sensor 2, controller 3, and display screen 4 are all located inside the housing 41. The housing 41 is generally embedded in the wall. The entire drive structure of this device can be the same as the drive structure of a smart control panel with a lifting knob published on August 2, 2022, with Chinese patent application number CN202220342957.4. This device requires the addition of sensor 2.

[0053] A human-computer interaction device is provided, comprising: a telescopic device 1, a sensor 2, a display screen 4, a controller 3, and a housing 41; the telescopic device 1, sensor 2, display screen 4, and controller 3 are all installed inside the housing 41; a limit switch 11 is provided at each end of the travel of the telescopic device 1; the sensor 2, the telescopic device 1, and the two limit switches 11 are all connected to the controller 3; the display screen 4 is installed on the telescopic device 1 and is installed inside the housing 41, allowing it to extend or retract via the telescopic device 1; the telescopic device 1 is a linear stepper motor, and the time taken for the telescopic device 1 to move from the inner end to the outer end or from the outer end to the inner end does not exceed 3 seconds; the sensor 2 is a microwave sensor with a monitoring range of 0.5 to 1 meter; and the display screen 4 is an LCD panel, enabling monitoring of personnel through the simple sensor 2 and allowing for pre-emptive action, making it convenient to use;

[0054] The telescopic device 1 is a linear stepper motor. This simple device can easily control the extension or retraction of the display screen 4. It is easy to use and has a simple structure. The time taken for the telescopic device 1 to move from the starting point to the ending point or from the ending point to the starting point is no more than 1 second. The display screen 4 is installed on the telescopic device 1. The display screen 4 can be extended and retracted into the housing 41 through the telescopic device 1. The display screen 4 is equipped with a backlight. The backlight is connected to the controller 3. The backlight starts and stops synchronously with the telescopic device 1.

[0055] The method includes the following steps:

[0056] In step S1, both the controller 3 and the sensor 2 are in a normally active state. The sensor 2 continuously monitors the external environment of the housing 41. The controller 3 determines whether the telescopic device 1 is in a retracted state or an extended state.

[0057] Step S2: When the telescopic device 1 is in the retracted state and an object is detected within the monitoring range, proceed to step S3.

[0058] When the telescopic device 1 is in the retracted state and no object is detected within the monitoring range, the sensor 2 remains in the activated state and does not operate.

[0059] When the telescopic device 1 is in the extended state and an object is detected within the monitoring range, return to step S1;

[0060] When the telescopic device 1 is in the extended state and no object is detected within the monitoring range, proceed to step S4;

[0061] Step S3: Sensor 2 sends a confirmation signal to controller 3. After receiving the confirmation signal from sensor 2, controller 3 controls telescopic device 1 to move outward. Telescopic device 1 moves outward until it abuts against the limit switch 11 at the outer end. Display screen 4 extends out of housing 41. Controller 3 controls telescopic device 1 to stop and returns to step S1.

[0062] Step S4: Sensor 2 sends a negative signal to controller 3. After receiving the negative signal from sensor 2, controller 3 starts telescopic device 1 to move inward. At the same time, controller 3 does not process the signal sent by sensor 2. Controller 3 controls telescopic device 1 to move in the opposite direction and retract until it abuts against the limit switch 11 at the inner end. Display screen 4 retracts into the housing 41. Controller 3 controls telescopic device 1 to close. After a delay of t1, controller 3 restarts processing the signal sent by sensor 2 and returns to step S1.

[0063] The telescopic device 1 is initially retracted into the housing 41. When the telescopic device 1 abuts against the limit switch 11 at the inner end, the controller 3 determines that the telescopic device 1 is in the retracted state. When the telescopic device 1 abuts against the limit switch 11 at the outer end, the controller 3 determines that the telescopic device 1 is in the extended state. This operation method, by first determining the position of the telescopic device 1 before operation and monitoring the surrounding environment, can effectively avoid or reduce malfunctions caused by unexpected travel.

[0064] This operating method can automatically correct the operation of the equipment by controlling the time of operation. It is simple to operate and has a low failure rate.
