New Description: [New Technology Field] This creation is a capacitive touch sensing device with environmental change correction, especially for an electric touch sensing device, which uses the reference capacitance to judge the environment. Change, correct the device for touch sensing. [Prior Art] • Due to advances in technology, the application of touch technology has been widely developed on many devices. For example, touch panels have become the most important application technology at present, and the touch technology of touch panels has resistive and electric valleys. Inductive, optical, etc., and capacitive touch technology has the characteristics of durability and low cost, and has gradually become the preferred technology for touch. At present, touchpads often have similar touch point capacitance values when there is touch and no touch. It is necessary to add complicated and immediate calculations and react quickly to avoid the device being affected by the external environment, which may cause misjudgment. . As shown in FIG. 1 , it is a schematic diagram of a conventional capacitive touch sensing device. The touch panel of the capacitive touch sensing device includes a plurality of touch sensing points, each of which is sensed. A point (hereinafter referred to as the sensing button 101) and the external environment can form an equivalent capacitance, and a sensing conversion unit 2 扫描 scans the sensing button 101 on each of the touch panels 100 in a sequence. The capacitance of these equivalent capacitors is converted to an inductance value. Then, the capacitive touch sensing device transmits the detected sensing value to the microprocessor 300, and the microprocessor 300 compares the amount of the current sensing value with the previous sensing value, and if the amount of change is When it is greater than a preset value, it is determined that the sensing button 101 has been touched or pressed, and when the amount of change is less than the set value, the sensing button 101 is considered not to be pressed. However, the conventional capacitive touch sensing device has a disadvantage in that if the external environment changes, the capacitance value of the equivalent capacitance of the sensing button 101 is affected, that is, the sensing value is changed by external production. When the amount of change in the sensed value is greater than a preset value, the microprocessor M383780 may mistake the sensor button 101 for being pressed. Although this problem can be avoided by bounce, if it is only a small amount of change in a short time, the problem of the misjudgment of the sensing button 101 cannot be completely solved in the case of continuous and long-term irregular changes. Therefore, in order to solve the above-mentioned lack of the existing capacitive touch sensing, the creator of the present invention has deliberately researched and proposed a capacitive touch sensing device that can solve the misjudgment of the sensing button caused by external environmental changes. [New content] The main purpose of this creation is to provide a capacitive touch sensing device with environmental change correction.卩 i i brother's culture;): The father is sensing the touch sensing value of the button on the touchpad to solve the misjudgment of the sensing button caused by the environmental change. In order to achieve the above purpose, the main technical feature of the present invention is to provide a capacitive touch sensing device with environmental change correction, which includes a touch panel having a plurality of sensing buttons thereon, each of which can be sensed. Forming-equivalent capacitance value; - reference capacitance, the capacitance value can be used as an environmental sensing value, - the first-sensing_changing unit is connected to the simple control board and the reference capacitance, and can scan the sensing buttons on the touch panel 'Detect the capacitance value of the equivalent capacitance of the sensing buttons, turn = should t, 'and = the capacitance value of the reference capacitance is changed to - the environment feels the U ratio = too t connects the brother - the sensing conversion The unit can record the touch sensing value and the environmental sensing value, first change whether the environmental reference sensing value is similar, and compare the result of the reference capacitance sensing value to the numerical operation correction, then whether there is a fiber that touch occurs. ^The riding test button is for the above purpose, the capacitive touch sensing device unit, the touchpad and the reference electronic book to create sub-synthesis skills to find the naturalization correction, which further includes - the switch, the system Connect the _ 容, you can cut the lining

Please refer to Figure 2 for the creation of a capacitive touch sensing device. The structure of the capacitive touch sensor _ thin and - micro-group 300 H touch panel touch, a first sensing transfer element ° There is a reference capacitor 400 and a switch 50D. The touch panel (10) is provided with a plurality of capacitive sensing buttons. a switch between the touch panel (10) and the first sensing conversion unit, the switch 500 can switch between the first chip or the reference capacitor 4t. When the capacitive touch sensing device connected to the touch panel is initialized, it first determines the reference capacitance 働 {brother-, the first action state shown in Figure 2, the switch #(10) will First, switch to the touch panel 100, scan the sensing button 1〇1 on it, and then convert the 200 to the current touch sensing value, and record the touch sensing value by the microprocessor. 4 is a schematic diagram of a second operational state shown in FIG. 4, the switch 500 is further switched to the connection and reference valley 400 to obtain an environmental sensing value from the first-sensing conversion unit 2()(). Comparing the ambient silk value with the previous discretionary environment money value, if there is a big difference between the two sensing values, the capacitance value of the reference capacitance 働 is changed, and then the scanning is performed by the first sensing conversion unit. Paying for the new environmental sensing value, the microprocessor will record the scan ring of this new environment. The value of the environment is again _. Repeat this process directly to the reference capacitor 400 processor 3 ^ Γ value and the recorded environmental sensing value difference within the allowable range, at this time micro-value, this loss of environmental sensing value, as the first reference capacitor 400 environmental reference sense reference: The capacitance value of the test capacitor 4GG is mainly used as the subsequent environmental reference capacitance value. The environmental sensing value made by the capacitance value is not affected by the external contact, and J will be changed by f pressure, and the temperature will be obtained. _(4) Find the external ring B & This feature can be used to separate the sensing button. 101 The amount of change in the sensed sense value is changed by external environmental factors. The key reference capacitance value is approximately equal to the equivalent capacitance value of the sensing button 101. The sensing value is the total capacitance value formed by the touch panel 100 including the sensing button 101 and the external environment. After the initialization of the capacitive touch-down position is created, the S-test button 101 on the touch panel 100 is scanned and it is determined whether a touch has occurred. Please click again, _change _ will switch to the connection control panel 100 ^ ^ sensing conversion unit 200 to get the touch sensing value of each sensing button 101, and then as shown in Figure 4, the _ The switch is further switched to connect the reference capacitance gamma, and the capacitance value of the tea-measuring capacitor 4G0 is set as the environmental reference capacitance value, the scanning is started, and the environmental sensing value is obtained by the first sensing conversion unit it 20G, the micro processing The device 3 (8) compares the current nuclear sensing value of the reference capacitor lion with the environmental reference value of the front-to-second reference capacitance of the recording towel. The right is that the change value of the comparison result is less than the predetermined value, which means that the external environment of the previous scan is similar to the external environment of the scan, so the touch_value of the sense button 1〇1 may not be used as a correction, and if the change value is greater than the county The environment of the neo- silk front reading and the environment of this scan have changed, so this time, the touch sensing value must be corrected according to the change of the reference capacitance sensing value before it can be used as the button (9). The basis for judgment. According to the above method, regardless of the external environment change, the environmental sensing value is increased or decreased, and the M383780 can successfully turn the thief should press the button 1G1 to correct the positive touchback field, as the touch of the seven touches. Reduce the occurrence of this _ capacitive touch control device malfunction 0 as shown in Figure 5 is not the shop [solid wire structure diagram, the sensor button 101 in the towel control panel 100 miscellaneous change unit 2 (8) to do the scanning depends on the control value, and add The first-sensing conversion unit is used as a sensing unit of the reference capacitor copper, so that the reference capacitance can be scanned by the second sensing conversion unit 201 to obtain an environmental sensing value. When the USB-based touch sensing device performs the above initialization and determines whether a touch occurs, the I, the sinusoidal conversion unit 200 and the second sensing conversion unit 201 simultaneously display the same to the sensing button 1 The touch sensing value of 〇1 and the ring-shaped sensing value of the reference capacitor 3(10) 彡 the same effect of tearing X to the external environment change, and the amount of change of the extinction value of the reference capacitor 3〇0 can be obtained. The real response of the sensor button 1 (10) is measured at the time of environmentalization = and the amount of change in the environmental sensing value of the reference capacitor 300 is numerically calculated, and the correct control button 1G1 can be used to control the ship, and thus the sensing device The occurrence of misoperations.
