Optionally, the high voltage sampling module 1 of the present embodiment includes a resistor R1, the low voltage input module 4 includes a resistor R2, the output module 5 includes a resistor R3, the switch control module 2 of the present embodiment includes a switch S1, a specific connection manner is shown in fig. 2, a voltage HVCC connected to the resistor R1 is a high voltage signal, a voltage VCC connected to the resistor R2 is a low voltage signal, and sources of two voltage signals may be voltages in a device applying the circuit of the present embodiment, because common peripherals all have own power supply, including an input high voltage and a converted low voltage signal for use by a device, when the circuit of the present embodiment is cited, the direct use of the peripheral voltage signal is more convenient and saves the use of the device, and meanwhile, the present embodiment does not need to use a device such as a transformer to achieve the purpose of high-low voltage conversion, and may further save space, volume, and the like.
The working principle is as follows: when the control switch S1 is closed, the cathode of the light emitter U1A is grounded, so that the light emitter U1A is conducted and emits light, and the light receiver U1B is conducted after receiving the light, so that the resistor R3 is grounded, and therefore the resistor R3 outputs a low-voltage signal to external equipment; when the switch S1 is turned off, the light emitter U1A is turned off, and does not emit light, and the light receiver U1B is turned off, and at this time, the resistor R3 outputs another low voltage signal to the external device through the voltage VCC connected to the resistor R2. Therefore, when the switch S1 is repeatedly turned on or off, the resistor R3 can output low-voltage signals with different levels, thereby realizing the control function on the peripheral equipment.
Embodiment two:
the difference between the high-voltage control device provided in this embodiment and the first embodiment is that, as shown in fig. 3, the switch module of this embodiment includes a controller 6 and a sliding resistor structure, an input end of the controller 6 is connected to an output end of the sliding resistor structure, an output end of the controller 6 is connected to the high-voltage sampling module 1, and the controller 6 is configured to output different PWM signals to the high-voltage sampling module 1; the sliding resistor structure comprises a sliding switch 7 and a plurality of resistor groups 8, the resistor values of the resistor groups 8 are different, one end of each resistor group 8 is connected with the input end of the controller 6, the other end of each resistor group 8 is provided with a connecting terminal, one end of the sliding switch 7 is connected with external power supply, and the other end of the sliding switch 7 is connected with different connecting terminals.
Specifically, as shown in fig. 3, the present embodiment sets the controller 6 to output different PWM pulse signals to the light emitter U1A, instead of the conventional switching on and off actions of the switch, different control signals are provided to the controller 6 through the sliding resistor structure, and the controller 6 changes the duty ratio of the PWM pulse signals according to the different resistance signals.
The sliding resistor structure is shown in fig. 4, a plurality of different resistor groups 8 are provided, each resistor group 8 comprises at least one resistor, as shown in fig. 3, a first resistor group 8 is provided with a single resistor, a second resistor group 8 is provided with two resistors connected in series, a third resistor group 8 is provided with three resistors connected in series, a fourth resistor group 8 is provided with four resistors connected in series, and so on, each resistor group 8 has different but definite resistance values, therefore, the sliding switch 7 is adjusted to different resistor groups 8 to obtain resistance signals with determined resistance values, compared with the sliding resistors in the prior art, the sliding switch 7 can obtain different resistance values, but cannot clearly determine the corresponding resistance values, or can only calculate the approximate resistance values, the sliding resistors in the prior art are applied to the embodiment, although the sliding resistors can give different resistance value signals to the controller 6, if each resistance value cannot clearly, the controller 6 cannot give out different resistance values, and therefore, the PWM signals can not give the PWM signals to the user, the PWM signals can not give the PWM signals to the actual control signals, and the PWM signals can be applied to the actual control signals, and the PWM signals can not be applied to the PWM signals, and the PWM signals can be controlled to the actual signals.
Further, the resistors included in the resistor group 8 may be provided by thin film resistors in order to reduce the volume thereof, so that the problem of excessively large volume of the sliding resistor structure is avoided.
As shown in fig. 4, the sliding switch 7 includes a support 9 and a sliding rod 10, the sliding rod 10 is mounted on the support 9, the sliding switch 7 is slidably mounted on the support 9, the resistor group 8 is mounted on the support 9, the sliding rod 10 is made of an insulating material, the sliding switch 7 includes a metal conductor core 11 and a first insulating layer 12 wrapped outside the metal conductor core 11, one end of the metal conductor core 11 is connected with external power supply, and the other end of the metal conductor core 11 is exposed outside the first insulating layer 12 and is used for being connected with a connecting terminal, so that the possibility of false touch can be avoided, and normal contact between the sliding switch 7 and the connecting rod 13 can be ensured.

Specifically, as shown in fig. 5, the structure of the connection terminal is that the lifting guide terminal 14 provided with the connection terminal mainly performs a limiting function on the sliding switch 7, for example, if the sliding switch 7 moves to be connected with a certain resistor group 8, if there is no other limiting structure, the sliding switch 7 is likely to shift during use, and the situation that the sliding switch 7 moves to change the resistance is likely to occur in the process of disconnection, including the sliding resistor in the prior art, so that the corresponding connection terminal is provided in each resistor group 8, the sliding switch 7 only needs to be connected with the corresponding connection terminal to provide a certain resistance value to the controller 6, therefore, in order to avoid the sliding switch 7 from shifting, as shown in fig. 8, the lifting guide terminal 14 is provided with an outer guide inclined plane 19 and an inner guide inclined plane 18, when the slide switch 7 moves from left to right, as shown in fig. 5, the slide switch 7 contacts the outer guide inclined surface 19, and the slide switch 7 makes the lifting guide terminal 14 lower the compression elastic member 16 under the guide action of the outer guide inclined surface 19 during the movement, when the slide switch 7 moves to the top of the outer guide inclined surface 19, the continuous movement can enter the hollow space of the lifting guide terminal 14, and because the inner guide inclined surface 18 is opposite to the outer guide inclined surface 19, before the slide switch 7 continues to move to the right to contact the connecting rod 13, the lifting guide sliding block gradually rises under the elastic force of the elastic member 16 and the inner guide inclined surface 18 gradually rises against the bottom end of the slide switch 7 until the slide switch 7 is connected into the connecting rod 13 and is limited in the lifting guide terminal 14, under the condition of no external force, the slide switch 7 is blocked by the elevation guide terminal 14 and is difficult to leave, so that the occurrence of the disconnection can be avoided. In addition, in the process of driving the sliding switch 7 to move by a user, the user can freely control the sliding switch 7 to enter and exit the lifting guide terminal 14, so that the lifting guide terminal 14 can not limit the functional use of the sliding switch 7.
Still further, as shown in fig. 7, the connecting rod 13 includes a conductive portion 21 and a supporting portion 22, the conductive portion 21 is integrally connected with the supporting portion 22, the conductive portion 21 is located in the expansion slot 17, the supporting portion 22 is located outside the expansion slot 17, and the outer periphery of the supporting portion 22 is wrapped with a second insulating layer 23. The connection manner between the connecting rod 13 and the resistor set is in the prior art, and the description of this embodiment is omitted.
Specifically, the connecting rod 13 is optionally supported by a metal conductor, so that in order to connect the sliding switch 7 with the resistor group 8, the conductive portion 21 of the connecting rod 13 does not cover the second insulating layer 23, and the end portion of the supporting portion 22 for connecting the resistor group 8 does not cover the second insulating layer 23, so that the sliding switch 7 can be normally connected with the connecting rod 13 in a signal manner when moving to the connecting rod 13. Further, the conductive layer 20 is also provided on the inner guide slope 18 in this embodiment, and as shown in fig. 5, the bottom of the conductive layer 20 of the inner guide slope 18 is in contact with the conductive portion 21 of the connecting rod 13, that is, the inner guide slope 18 is electrically connected to the connecting rod 13, so that when the slide switch 7 is in contact with the inner guide slope 18, it is already electrically connected to the connecting rod 13, that is, to the corresponding resistor group 8, and the conductive layer 20 of the inner guide slope 18 is provided so that the slide switch 7 can be in contact with the conductive layer 20 of the inner guide slope 18 even if there is displacement within a certain range, so as to be able to maintain electrical connection with the connecting rod 13, thereby reducing the risk of disconnection, as long as within the hollow space of the lifting guide terminal 14.
Furthermore, the supporting portion 22 of the connecting rod 13 is wrapped with an insulating layer, and the lifting guide terminal 14 is made of a non-conductive material, so that the possibility of false contact between the outside and the connecting terminal is reduced.
As shown in fig. 7 and 8, the lifting guide terminal 14 is convexly provided with a limiting ring 24, the limiting ring 24 is sleeved on the connecting rod 13, the telescopic frame 15 is convexly provided with an anti-falling ring 25, the anti-falling ring 25 is positioned at the outlet of the telescopic slot 17 and used for limiting and anti-falling the lifting guide terminal 14, so that the lifting guide terminal 14 cannot be separated from the telescopic slot 17, and therefore, the lifting guide terminal 14 can be limited and positioned through the limiting ring 24 and the anti-falling ring 25 in the lifting process of the lifting guide terminal 14, and the lifting guide terminal 14 cannot move out of the telescopic slot 17 in the moving process. The inner wall of the stop collar 24, which is in contact with the conductive end of the connecting rod 13, is also provided with a conductive layer 20, and the conductive layer 20 of the stop collar 24 is electrically connected with the conductive layer 20 of the inner guiding inclined plane 18, so that the conductive layer 20 of the inner guiding inclined plane 18 can be stably electrically connected with the connecting rod 13 in the moving process.
