Description

Technical Field

[0001] The invention belongs to the field of electronic measuring instruments, and in particular relates to a touch control component including a virtual wheel and an electronic measuring instrument. Background Art

[0002] In the field of electronic measuring instruments, the panel is the main interface for the operator to interact with the instrument. The operator achieves the purpose of measuring and controlling the instrument by operating the knobs, wheels, buttons and other functions in various functional areas on the instrument panel. At present, more and more full touch screens are used in instruments to replace the original panels. In this process, the original physical buttons and knobs are replaced by virtual keyboards and virtual knobs one by one.

[0003] In the prior art, virtual keyboards and virtual scroll bars are mostly used. Among them, virtual scroll bars are generally only used in conjunction with a fixed parameter. Different parameters require multiple different virtual scroll bars to be configured, and one-to-many cannot be achieved. At present, most virtual keyboards used on the touch screen of electronic measuring instruments pop up at a fixed position and cannot be dragged. They are not suitable for one-handed operation, and there is an inconvenience in operating when setting parameters; and the virtual keyboard covers an area that is too large, which affects the real-time observation of measurement results during the parameter setting process. Summary of the invention

[0004] In view of the above technical problems, the present invention provides a touch control component and an electronic measuring instrument including a virtual wheel. The touch control component and the electronic measuring instrument provided by the present invention can more conveniently realize the operation of setting parameters with one hand, and it is more convenient to observe the measurement results while setting the parameters.

[0005] The present invention is achieved through the following technical solutions:

[0006] A touch control component including a virtual rotating wheel is used in an electronic measuring instrument, the touch control component including: a touch control panel and a signal processor;

[0007] The touch panel is used for displaying the electronic measuring instrument parameter information, the virtual wheel and identifying the touch operation, and sending the touch signal generated by the touch operation to the signal processor;

[0008] The signal processor is used to receive the touch signal and analyze the touch operation according to the touch signal: when it is analyzed that the touch operation is to click on a menu for setting parameters, open the virtual wheel;

[0009] After the virtual wheel is turned on, when the signal processor identifies that the touch operation is located at the display position of the virtual wheel, the signal processor receives a touch signal corresponding to the touch operation and analyzes the touch operation according to the touch signal.

[0010] Furthermore, the virtual wheel has an appearance of a rectangle, the lateral width of the rectangle is smaller than the longitudinal length, and the virtual wheel includes a virtual upper key, a virtual lower key, and a wheel from top to bottom.

[0011] Further, after the virtual wheel control is turned on, the signal processor analyzes the touch operation according to the touch signal, specifically:

[0012] When it is analyzed that the touch operation is dragging the virtual key up and / or the virtual key down, dragging the virtual wheel control to the position where the touch point last stopped;

[0013] When it is analyzed that the touch operation is clicking the upper key of the virtual key or the lower key of the virtual key, an upward single-step stepping signal or a downward single-step stepping signal is generated, and the upward single-step stepping signal and the downward single-step stepping signal are used to perform single-step adjustment on the specified parameter in the electronic measuring instrument;

[0014] When it is analyzed that the touch operation is sliding the wheel upward or downward, an upward multi-step step signal or a downward multi-step step signal is generated, and the upward multi-step step signal and the downward multi-step step signal are used to perform multi-step adjustment on the specified parameters in the electronic measuring instrument;

[0015] When the touch operation is analyzed to be a long press of the wheel, a background and transparency setting window pops up, and the background and transparency setting window is used to set the background color or background image and transparency of the virtual wheel. By adjusting the background and transparency of the virtual wheel, the virtual wheel can minimize the occlusion of the test measurement results.

[0016] Furthermore, when determining the sliding direction of the wheel, the determination method adopted is to record the current item sequence number currentIndex of the Tumbler control, respond to the currentIndexChanged() signal of the Tumbler control, and then compare the changed current item sequence number with the recorded last sequence number. If the sequence number becomes larger, it is determined that the wheel is sliding upward, and if the sequence number becomes smaller, it is determined that the wheel is sliding downward.

[0017] When the sequence number is at the maximum and minimum values, it is necessary to determine whether the wheel has slid to a new circle, so as to correctly determine the sliding direction of the wheel.

[0018] Furthermore, the signal processor is further configured to stop adjusting the designated parameters in the electronic measuring instrument when it is determined that the click or slide operation is ended.

[0019] Furthermore, the specified parameters in the electronic measuring instrument are adjusted, including adjusting the step value and adjusting the waiting time.

[0020] An electronic measuring instrument comprises a touch control component and an electronic measuring circuit.

[0021] Beneficial technical effects of the present invention:

[0022] The touch component provided by the present invention includes a virtual wheel, which has the appearance and action of a wheel, can receive and identify touch events, and supports dragging, modifying background transparency, and convenient single-finger operation to set parameters while holding the device; thus enhancing the human-computer interaction experience of electronic measuring instruments.

[0023] Compared with the virtual keyboard and virtual scroll bar in the prior art, the touch component provided in the present invention includes a virtual wheel, which can slide up or down endlessly, and the sliding is for setting parameters, while the virtual scroll bar in the prior art has a certain range of sliding up or down.

[0027] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0028] On the contrary, the present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention as defined by the claims. Further, in order to make the public have a better understanding of the present invention, some specific details are described in detail in the detailed description of the present invention below. Those skilled in the art can fully understand the present invention without the description of these details.

[0029] The present invention provides an embodiment of a touch control component including a virtual wheel, which is used in an electronic measuring instrument, wherein the touch control component includes: a touch control panel and a signal processor;

[0030] The touch panel is used for displaying parameter information of the electronic measuring instrument, virtual conversion and identifying touch operations, and sending touch signals generated by the touch operations to the signal processor;

[0031] The signal processor is used to receive the touch signal and analyze the touch operation according to the touch signal: when it is analyzed that the touch operation is to click on a menu for setting parameters, open the virtual wheel;

[0032] After the virtual wheel control is turned on, when the signal processor identifies that the touch operation is located at the display position of the virtual wheel, the signal processor receives a touch signal corresponding to the touch operation and analyzes the touch operation according to the touch signal.

[0033] like Figure 1 As shown, the virtual wheel has an appearance of a rectangle, the lateral width of the rectangle is smaller than the longitudinal length, and the virtual wheel includes a virtual upper key 1, a virtual lower key 2, and a wheel 3 from top to bottom.

[0034] In this embodiment, after the virtual wheel control is turned on, the signal processor analyzes the touch operation according to the touch signal, such as Figure 2 As shown, specifically:

[0035] When it is analyzed that the touch operation is dragging the upper key of the virtual button and / or the lower key of the virtual button, the virtual wheel control is dragged to the position where the touch point last stopped; specifically, when the upper key of the virtual button and / or the lower key of the virtual button are dragged without releasing the hand, the virtual wheel can be dragged as a whole, and according to the actual usage scenario, the virtual wheel can be dragged to the leftmost or rightmost side of the touch screen, so as to facilitate the instrument parameter setting operation while holding the hand.

[0036] When it is analyzed that the touch operation is clicking the upper key of the virtual key or the lower key of the virtual key, an upward single-step stepping signal or a downward single-step stepping signal is generated, and the upward single-step stepping signal and the downward single-step stepping signal are used to perform a single-step adjustment on the specified parameter in the electronic measuring instrument; that is, clicking the "upper key of the virtual key" or the "lower key of the virtual key" can trigger a single step up or down of the parameter.

[0037] When the touch operation is analyzed to be sliding the wheel upward or downward, an upward multi-step step signal or a downward multi-step step signal is generated, and the upward multi-step step signal and the downward multi-step step signal are used to perform multi-step adjustments on the specified parameters in the electronic measuring instrument. Specifically, multiple step operations are performed according to the sliding direction and distance, and the effect is similar to multiple clicks on the virtual key up or the virtual key down;

[0038] When the touch operation is analyzed to be a long press of the wheel, a background and transparency setting window pops up, and the background and transparency setting window is used to set the background color or background image and transparency of the virtual wheel. By adjusting the background and transparency of the virtual wheel, the virtual wheel can minimize the occlusion of the test measurement results.

[0039] In this embodiment, when determining the sliding direction of the wheel, the determination method adopted is to record the current item sequence number currentIndex of the Tumbler control, respond to the currentIndexChanged() signal of the Tumbler control, and then compare the changed current item sequence number with the recorded last sequence number. If the sequence number becomes larger, it is determined that the wheel is sliding upward, and if the sequence number becomes smaller, it is determined that the wheel is sliding downward.

[0040] Taking the Tumbler control with 20 elements as an example, the function for determining the sliding direction is as follows:

[0041]

[0042]

[0043] Among them, lastIndex is the last sequence number recorded, currentIndex is the current sequence number recorded, upBtnClicked() is the upward step signal sent, and downBtnClicked() is the downward step signal sent.

[0044] When the sequence number is at the maximum and minimum values, it is necessary to determine whether the wheel has slid to a new circle, so as to correctly determine the sliding direction of the wheel.

[0045] In this embodiment, the signal processor is further configured to stop adjusting the specified parameters in the electronic measuring instrument when it is determined that the click or slide operation is ended.

[0046] In the present invention, the signal processor includes a touch signal receiving module, an analyzing module, a parameter adjusting module, and an adjustment stopping module;

[0047] A touch signal receiving module, used for receiving a touch signal corresponding to a touch operation in the touch panel;

[0048] An analysis module, used for analyzing the touch operation according to the touch signal;

[0049] A parameter adjustment module, used for adjusting a specified parameter in the electronic measuring instrument after the analysis module analyzes the touch operation;

[0050] The adjustment stop module is used to stop adjusting the specified parameters in the electronic measuring instrument when the analysis module analyzes that the click or slide operation ends. In the present invention, the signal processor adopts conventional technology.

[0051] In this embodiment, the specified parameters in the electronic measuring instrument are adjusted, including adjusting the step value and adjusting the waiting time.

[0052] When precise parameter value setting is required, a traditional virtual keyboard can be used; when dynamic adjustment of parameters is required to observe measurement results, the virtual wheel of the present invention can be used. When the virtual wheel of the present invention rotates, other parameter setting pages such as the virtual keyboard are immediately closed, which is convenient for one-handed operation and convenient for setting parameters while observing measurement results. The position, background color and transparency of the virtual wheel of the present invention can be manually configured as needed.

[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
