Form number Α0101, page 9/19 pages 0992060130- [0035] 201216213 200, the time comparison unit 300 and the trigger path determining unit 500, the reset unit 700 provides a reset signal to reset the transmitting unit 100, the receiving unit 200, the time comparing unit 300, and The trigger path determining unit 500 causes the transmitting unit 100, the receiving unit 200, the time comparing unit 300, and the trigger path determining unit 500 to return to an initial state. [0036] The operating principle of the non-touch switching device is as follows: [0037] The transmitting unit 100 is configured to send a detection signal and activate the timing function of the timing unit 400. The receiving circuit 200 receives the foreign object entering the predetermined transmission range, and blocks the detection signal. Generating a reflected signal and a foreign object trigger signal, and transmitting the reflected signal and the foreign object trigger signal to the time comparison unit 300, wherein the foreign object trigger signal is It contains a start trigger time and a moving path of a foreign object. Simultaneously, the timing unit 40 0 stops the timing function and converts the timing result into a time signal and passes it to the time comparison unit 300. [0038] The time comparison unit 300 compares the time signal with the comparison signal to determine whether the foreign object is located within the predetermined transmission range, and the determination manner is that the detection signal is transmitted to the transmitting unit 100 to be received by the receiving unit. The transmission time received by the unit 200 is used to distinguish the distance between the foreign object and the application system, and the judgment formula is as follows: [0039] Time signal = (distance between the foreign object and the non-touch switch device x2) + speed of light, [0040] When time When the signal is less than or equal to the comparison signal, it is determined that the foreign object is located within the predetermined emission range, and a confirmation signal is transmitted and the foreign object is triggered. 099134432 Form No. A0101 Page 10 / 19 pages 0992060130-0 201216213 [0041] [0042] ❹ 099134432 signal to the trigger path determining unit 5 〇0 to confirm the foreign object trigger signal for the foreign object action; and if the time signal is greater than the comparison signal, it is determined that the foreign object is located in the predetermined launch range And transmitting a misidentification signal to the reset unit 700' to drive the reset unit 7 to reset the transmitting unit 100, and the receiving unit 200 compares with the time 300, the reply to the initial state. The above-mentioned time-distance judgment can effectively avoid the situation of misjudgment caused by the background brightness or the material of the reflector when the light intensity of the infrared signal is used as a judgment condition. Then, the trigger path determining unit 500 performs a trigger signal determination for the foreign object located within the preset transmission range to avoid a situation in which the foreign object is malfunctioned due to being close to the application system. When the trigger path judging unit 500 receives the acknowledgment signal and the foreign object trigger signal transmitted by the time comparing unit 300, it is determined whether the foreign object trigger signal conforms to the predetermined trigger signal or not. If the foreign object trigger signal passes the trigger path, and the determining unit 500 confirms that the predetermined trigger signal is completely met, that is, the start trigger time is less than or equal to the predetermined trigger time, and the moving path of the foreign object conforms to the predetermined trigger path, then determining The object outside the emission range is intended to activate the application device and deliver a start signal to the output unit 600. If the foreign object triggering signal is confirmed by the trigger path determining unit 500 to not fully meet the predetermined triggering signal, that is, the starting triggering time is greater than the predetermined triggering time or the moving path of the foreign object does not meet the predetermined triggering path, then the determining is located in the transmitting range. The internal and external materials have to activate the application system; and 'the trigger path judging unit 500 transmits a misidentification signal to the reset unit 700' to drive the reset unit 700 to reset the transmitting unit 100, the form number Α0101 Page 11 of 19 0992060130-0 201216213 The receiving unit 200, the time comparing unit 300 and the trigger path determining unit 50 0 return to the initial state. In this embodiment, the predetermined trigger signal is that the foreign object must complete at least two consecutive swings in different directions within the predetermined trigger time, such as: waving left and right. [0043] Referring to the second figure, a flow chart of the operation method of the non-touch switch device of the present invention is shown. The non-touch switch device is installed in an application system for detecting whether a foreign object is desired to pass. The operation method of the non-touch switch device is as follows: [0044] 1. The detection unit 100 actively and continuously transmits a detection signal (step S800), wherein the transmission unit 100 has a predetermined emission range. [0045] 2. While the transmitting unit 100 emits an infrared signal, the timing function of the timing unit 400 is activated (step S802). [0046] 3. The receiving unit 200 receives a reflected signal that is blocked by the foreign object to generate a reflection and a foreign object trigger signal (step S804), and transmits the reflected signal and the foreign object trigger signal to the time comparison unit. 300. At the same time, the timing function of the timing unit 400 is stopped and the timing result is transmitted to the time comparison unit 300 as a time signal. [0047] 4. The time comparison unit 300 receives the reflected signal, the foreign object trigger signal and the time signal, and records the foreign object trigger signal, and then determines, by the time signal, whether the reflected signal reflects within a predetermined distance. That is, whether the foreign object passes within a predetermined distance (step S806). If not, the process returns to step S800 to re-issue the detection signal; if so, the foreign object trigger signal is transmitted to the trigger path determination unit 500. [0048] 5. In step S806, and receiving the foreign object trigger signal that is executed, the judgment 099134432 Form No. A0101 Page 12 / 19 pages 0992060130-0 201216213 [0049] [0051] 005 [0052] [ [0057] [0057] [0057] The foreign object trigger signal is broken to meet a predetermined trigger signal (step S808). If not, the process returns to step S800 to re-issue the detection signal; if so, an activation signal is output for starting the application device (step S810). In summary, the non-touch switch device of the present invention passes through a two-stage determination process to confirm whether the foreign object is to start the application system: 1. The first stage first confirms whether the foreign object is located at a predetermined distance, that is, Use time to calculate the distance; 2. The second stage is to judge whether the foreign object reaches a complete trigger signal, and the trigger signal is directed to the directional determination of the foreign object; thus effectively avoiding the external light damage or high reflection material The malfunction of the application device, and the user does not need to directly press the switch, and the virus or bacteria can be prevented from being cross-transferred when the switch is touched.
