Detailed Description

The invention is described in detail below with reference to the figures and the embodiments.

As shown in fig. 1, an isolated high-voltage touch switch 10 according to the present invention includes: the device comprises an alternating current power supply 11, an alternating current-direct current conversion module 12, a touch panel 13, a direct current touch controller 14, a high-voltage switch 15 and alternating current equipment 16. The ac-dc conversion module 12 is configured to convert ac power provided by the ac power supply 11 into dc secondary power. The touch panel 13 is used for being touched by a user to generate a touch instruction. The dc touch controller 14 is configured to receive a touch instruction and generate a control signal according to the touch instruction. The high-voltage switch 15 is used for receiving control commands and executing the control commands. Specifically, the ac power source 11 is electrically connected to the ac/dc conversion module 12 and the high voltage switch 15. The ac/dc conversion module 12 is electrically connected to the touch panel 13 and the dc touch controller 14. The high voltage switch 15 is electrically connected to an ac device 16.

Further, the isolated high-voltage touch switch 10 further includes: and an isolation module 17. The isolation module 17 is configured to receive the control signal and process the control signal to generate a control instruction. The isolation module 17 is electrically connected to the ac-dc conversion module 12, the dc touch controller 14 and the high voltage switch 15.

Specifically, after the ac device 16 is connected to the ac power source 11, the ac/dc conversion module 12 converts the ac power source 11 to generate a safe dc secondary power source. The dc secondary power supplies power to the dc touch controller 14, the touch panel 13, and the isolation module 17, so that the three enter a working state. At this time, the touch panel 13 generates a touch instruction, the first touch instruction is a start instruction, the dc touch controller 14 receives the first touch instruction and then analyzes the first touch instruction, the analyzed instruction is transmitted to the isolation module 17 in a logic signal manner, and the isolation module 17 performs waveform shaping and level conversion on the signal and then transmits the signal to the control end of the high-voltage switch 15. By such a workflow, the high-voltage switch 15 is closed, and the ac device 16 starts to operate by receiving power. When the touch panel 13 is touched again, the touch controller receives the touch instruction sent by the touch panel again, the second touch instruction is a closing instruction, the direct current touch controller 14 receives the second touch instruction and then analyzes the second touch instruction, the analyzed instruction is transmitted to the isolation module 17 in a logic signal mode, and the isolation module 17 carries out waveform shaping and level conversion on the signal and then sends the signal to the control end of the high-voltage switch 15. Through such a workflow, the high-voltage switch 15 turns off the ac power supply 11 of the ac device 16 according to the instruction, and the system is shut down.

The isolated high-voltage touch switch 10 can ensure the touch safety of the touch pad 13 through the alternating current-direct current conversion module 12 and the isolation module 17, and can avoid the occurrence of safety accidents caused by alternating current back strings due to failure of the high-voltage switch 15 in the working process, thereby ensuring the use safety of the high-voltage touch switch. That is to say, the ac/dc conversion module 12 converts the high-voltage 220V ac power supply 11 into a dc power supply and then provides the dc power supply to the dc touch controller 14, the touch panel 13 and the isolation module 17, so that the direct transmission of the high-voltage 220V ac power supply 11 to the dc touch controller 14, the touch panel 13 and the isolation module 17 can be avoided, and the situation that a user is easily damaged by the high-voltage 220V ac power supply 11 when directly touching the touch panel 13 is avoided. Meanwhile, the isolation module 17 is arranged between the direct current touch controller 14 and the high-voltage switch 15, so that the safety problem of alternating current back-to-serial caused by burning or failure of the high-voltage switch 15 in the working process can be prevented, and the effect of operating the alternating current equipment 16 by isolated safe touch can be achieved.

Furthermore, the isolated high-voltage touch switch 10 further includes: a display module 18. The display module 18 is used for displaying fault information when the high-voltage switch 15 is in fault. The display module 18 is electrically connected to the dc touch controller 14. When the high-voltage switch 15 has a fault, a fault signal is transmitted to the dc touch controller 14, and the dc touch controller 14 converts the fault signal into fault information and sends the fault information to the display module 18. This is the display module 18 that is able to display the fault information to the user.

In this scheme, isolated high voltage touch switch 10 still includes: and a power detection control module 19. The power detection control module 19 is configured to detect a voltage value of the ac power supply 11 and stop supplying power to the ac-dc conversion module 12 when detecting that the voltage value of the ac power supply 11 is greater than a preset value. The power detection control module 19 is electrically connected to the ac power supply 11 and the ac/dc conversion module 12. The voltage of the ac power supply 11 that can be converted by the ac/dc conversion module 12 is limited. If the voltage of the ac power supply 11 is too high, the ac/dc conversion module 12 may be damaged, so the power supply detection control module 19 stops supplying power to the ac/dc conversion module 12 when detecting that the voltage value of the ac power supply 11 is greater than the preset value, and the working safety of the ac/dc conversion module 12 can be ensured.

As a specific scheme, the isolated high-voltage touch switch 10 further includes: a second switch 20. The second switch 20 is configured to be turned on when the display module 18 receives a message that the high voltage switch 15 is faulty, so as to supply power to the ac device 16. The second switch 20 is electrically connected to the display module 18 and the ac device 16. That is, when the high voltage switch 15 malfunctions, the display module 18 sends activation information to the second switch 20. At this time, the second switch 20 is energized to supply power to the ac device 16. By adopting the structure, the situation that the alternating current equipment 16 is suddenly powered off and cannot be used due to the sudden fault of the high-voltage switch 15 can be avoided, and the normal work of the alternating current equipment 16 is not influenced.

Further, the isolated high-voltage control switch 10 further includes: a second detection module 21. The second detecting module 21 is configured to detect the voltage stability of the second switch 20 and send the detection information to the display module 18, so that a user can know the usage status of the second switch 20 in real time, and thus the user can deal with the status of the second switch 20 in time. The second detection module 21 is electrically connected to the display module 18 and the second switch 20. The current of the display module 18 is detected by the second detection module 21 and then passes through the second switch 20.

As a specific implementation manner, the isolated high-voltage touch switch 10 further includes: a transformer 22. The voltage transformation device 22 is used for transforming the voltage of the alternating current power supply 11 with the voltage value larger than the preset value. Thus, when the power detection control module 19 detects that the voltage provided by the ac power supply 11 is greater than the preset value, the power provided by the ac power supply 11 is controlled to be transformed by the transformation device 22 and then input to the ac-dc conversion module 12 for ac-dc conversion. This can expand the range of use of the voltage of the ac power supply 11. The transformer 22 is electrically connected to the ac power supply 11, the power detection control module 19, and the ac/dc conversion module 12.

In one specific embodiment, the high voltage switch 15 is a semiconductor conductive device.

Specifically, the high voltage switch 15 is a thyristor semiconductor switch. Such a high-voltage switch 15 can prevent the ac string-back safety problem caused by the burning or failure of the high-voltage switch 15 during operation.

The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It should be understood by those skilled in the art that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by using equivalent alternatives or equivalent variations fall within the scope of the present invention.
