All other embodiments obtained by persons of ordinary skill in the art based on the embodiments in the present application without creative work are within the scope of protection of the present application.
[0023] Example
[0024] like Figures 1 to 5 As shown, a debugging device suitable for a laser navigation puncture device includes a PCB board, to which a power supply unit 1, a DC-DC conversion unit 2, an anti-shake unit 3, a level conversion unit 4, an MCU unit 5 and a laser emission control unit 6 are connected. The output end of the power supply unit 1 is connected to the input end of the DC-DC conversion unit 2, the output end of the DC-DC conversion unit 2 is connected to the input end of the MCU unit 5, the output end of the MCU unit 5 is connected to the input end of the anti-shake unit 3, the output end of the MCU unit 5 is connected to the input end of the level conversion unit 4, and the output end of the MCU unit 5 is connected to the input end of the laser emission control unit 6. The PCB board is also connected to a communication interface 11, an input / output interface 7, a Spi interface 8, a power interface 9 and a stepper motor interface 10, wherein the communication interface 11, the input / output interface 7, the Spi interface 8 and the stepper motor interface 10 are connected to the MCU unit 5, and the power interface 9 is connected to the power supply unit 1.
[0025] The chip model of the MCU unit 5 in the present invention is STM32F103C8, which is a 32-bit ARM core-based microcontroller with 64 or 128K bytes of flash memory, USB, CAN, 7 timers, 2 ADCs, and 9 communication interfaces.
[0026] The DC-DC converter unit 2 described in this utility model uses an MC14027 chip, a standard CMOS logic circuit. The unit contains two independent JK flip-flops. The first flip-flop is connected to a monostable multivibrator, generating a positive pulse of a specified width. The second flip-flop is connected to a bit counter, and when a positive pulse reaches its input, it changes its output state.
[0027] When the on / off switch is pressed, pin 4, reset, goes low. In this state, the Q output is low. When the switch is released, the Q output rises within the time specified by R3 and C2. The Q output is fed into the input of a two-bit counter, where its state changes. When on, the counter's Q output goes high. This high level is connected to the base pin of Q1. Q1 begins conducting and pulls the base pin of Q2 low. Q2, a PNP power transistor, also begins conducting. Q2 acts as the main power switch, supplying all power from the battery to the unit circuits. The microcontroller can turn off the switch using the reset pin on the second flip-flop. To ensure that this switch can operate even when the power is off, circuit U5 is powered by a 6V battery. Current consumption is very low, approximately 1µA.
[0028] The chip model of the level shifter unit 4 described in this utility model is TXS0108, an eight-channel bidirectional level shifter conversion chip. This eight-bit non-inverting shifter uses two independent configuration power supplies. Port A tracks the power supply voltage of the VCCA pin. The VCCA pin can accept any power supply voltage in the range of 1.2 volts to 3.6 volts. Port B tracks the power supply voltage of the VCCB pin. The VCCB pin can accept any power supply voltage in the range of 1.65 volts to 5.5 volts. These two input power supply pins can achieve any low-voltage bidirectional conversion between output voltage nodes of 1.2 volts, 1.8 volts, 2.5 volts, 3.3 volts, and 5 volts.
[0029] When the output enable input is low, all outputs are placed in a high-impedance state. To ensure that the outputs are in a high-impedance state between power-up and power-down, connect OE to GND through a pull-down resistor.
[0030] Laser emission control unit, D4 and D5 together with R8 and R9 reduce the voltage by about 2 × 0.75V, leaving 3.5V for the laser, where R8 and R9 reduce the peak startup current of transistors Q8 and Q9 to acceptable limits.
[0031] The anti-shake unit is a switching circuit and can be divided into two situations: the first is when the button is pressed, and the second is when the button is released.
[0032] When a key is not pressed, the capacitor and resistor are connected in series between the 3.3V power supply and ground. The voltage across the capacitor is 3.3V, and the capacitor has no transient potential change. When the key is pressed, the capacitor's instantaneous state is V = 3.3V, and the capacitor begins to discharge, gradually decreasing the voltage across it. From then on, the voltage across the capacitor gradually decreases. By determining the values of the resistor and capacitor, and the time required for the voltage change, when the key is pressed, the time required for the voltage to change from 0 to 3.3V only takes nanoseconds, thus preventing jitter. Similarly, anti-shake can be achieved when the key is released.
[0033] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.
[0034] In the description of this application, it should be noted that the terms "vertical," "horizontal," "inner," and "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, or are the orientations or positional relationships in which the product of this application is typically placed when in use. These terms are intended solely to facilitate the description of this application and simplify the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," etc., etc., are used solely to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0035] In addition, the terms "horizontal" and "vertical" do not mean that the components must be absolutely horizontal or vertical, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.
[0036] It should also be noted that, in the description of this application, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.
[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
