TECHNICAL FIELD
[0001] The utility model relates to electronic product technical field especially is related to a programmable key switch power supply circuit. BACKGROUND
[0002] In modern data acquisition and processing systems, efficient operation of devices and smoothness of human-computer interaction are crucial. Traditional data acquisition devices usually rely on fixed power control mechanisms, which cannot flexibly adapt to different operating scenarios and user needs. In some special application scenarios, such as real-time operation according to the running state of the device and external indication, the traditional key switch circuit is not up to the task.
[0003] The existing key switch circuit usually only provides a simple power on-off function, and cannot effectively link with the program running of the processor. This independent operation mode limits the flexibility of users in the data acquisition and processing process, especially in the case of manual intervention, which is particularly inconvenient. In addition, although the circuit design controlled entirely by the program can realize automatic operation, it lacks the intuitiveness and flexibility of human-computer interaction in some situations that require human participation.
[0004] Therefore, in order to meet the needs of modern devices for flexibility, aesthetics and low power consumption, it is particularly important to design a programmable key switch circuit. This circuit not only enables manual control through the key, but also effectively combines with the program running state of the processor to realize intelligent power supply control of the data acquisition device. Through this design, users can manually control the power-on state of the acquisition device when the processor needs to process data, thereby realizing efficient acquisition and transmission of data. In addition, through the optimization of the key design, the aesthetics and thinness of the device control panel can be realized, and the overall user experience can be improved.
[0005] In summary, in order to solve the limitations of traditional key switch circuits, a programmable key switch power supply circuit is developed, which can not only realize the collaborative work of manual and program, but also meet the high standards of appearance and function of modern devices, and has important practical significance.

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below, obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.
[0021] The utility model embodiment aims at providing a programmable key switch power supply circuit, to solve the problem that the traditional power supply control scheme design lacks the intuitiveness and flexibility of man-machine interaction, and thus cannot flexibly adapt to different operation scenes and user requirements. At the same time, it can also meet the high standard requirements of modern devices on appearance and function.
[0022] Please refer to Figure 1 , Figure 1 It is the overall architecture diagram of the programmable key switch power supply circuit provided by the utility model. In the embodiment, the programmable key switch power supply circuit mainly consists of a programmable module 101 and a key switch power supply module 102, wherein the key switch power supply module 102 mainly consists of a key circuit module 201, a D flip-flop module 202 and a power output control module 203.
[0023] Please refer to Figure 2 , Figure 2 It is the circuit principle diagram of the programmable module provided by the utility model. The programmable module mainly consists of a processor 1011, a triode Q1, a resistor R1, a resistor R2, a resistor R3 and a light-emitting diode D1. The processor 1011 controls the on-off of the light-emitting diode D1 through the high-low level of the LED pin. After the system is powered on, the LED pin is at low level and the Control pin is at high level by default. At this time, the light-emitting diode D1 is in the extinguishing state, and the triode Q1 is in the conducting state, and the P-OUT pin is at low level.
[0024] Please refer to Figure 3 , Figure 3 It is the circuit principle diagram of the key switch power supply module provided by the utility model. The key switch power supply module mainly consists of a resistor R3, a resistor R4, a resistor R5, a capacitor C1, a key K1 and a triode Q2. After the system is powered on, the triode Q2 is in the reverse conducting state by default, and the PWCLK pin is at low level. When the key K1 is pressed, the base voltage of the triode Q2 and the voltage between the emitter stage are less than the conducting voltage of the triode Q2, so the triode Q2 is in the cut-off state, and the PWCLK pin is pulled up to high level by the resistor R4 and the power supply VCC, thereby generating the rising edge of the PWCLK pin level from low to high.
[0025] Please refer to Figure 4 , Figure 4This is a circuit schematic of the D flip-flop module provided by this utility model. The D flip-flop module mainly consists of a D flip-flop U1, resistor R7, capacitor C2, and capacitor C3. Resistor R7 and capacitor C3 form a simple reset circuit. After the system is powered on, capacitor C3 is charging, so the / CLR pin of the D flip-flop is low. At this time, the output pin BAT-Ctl of the D flip-flop is low, which is the circuit reset time. Figure 3 Button K1 cannot change the state of the output pin BAT-Ctl. When capacitor C3 is fully charged, the circuit reset ends, and the / CLR pin of the D flip-flop goes high. At this time, clicking... Figure 3 After pressing button K1, a rising edge is input to the PWCLK pin of the D flip-flop, and the output pin BAT-Ctl of the D flip-flop is determined by the state of the P-OUT pin. The state of the P-OUT pin is mainly determined by... Figure 2 The conduction state of transistor Q1 shown is related to the following: Figure 2 The conduction of transistor Q1 shown is mainly due to Figure 2 The level of the Control pin of the processor 1011 shown is determined.
[0026] Please see Figure 5 , Figure 5 This is a circuit schematic diagram of the power output control module provided by this utility model. The power output control module mainly consists of transistors Q3 and Q4, resistors R8, R9, R10, and R11, and capacitor C4. Figure 5 When the BAT-Ctl pin is low, transistor Q3 is in the off state, therefore transistor Q4 is also in the off state, and the collector output of transistor Q4 is 0. Since the VCC-OUT pin is connected to the collector of transistor Q4, the output voltage is also 0. When... Figure 5 When the BAT-Ctl pin is high, transistor Q3 is in the conducting state, so transistor Q4 is also in the conducting state. The collector output of transistor Q4 is equal to VCC. Since the VCC-OUT pin is connected to the collector of transistor Q4, the output voltage is also equal to VCC. That is, the output voltage of the entire power output control module circuit is VCC. Resistor R11 and capacitor C4 form the filtering circuit for the voltage output of the power output control module circuit.
[0027] After the entire programmable push-button power supply circuit is powered on, Figure 2 The processor 1011 program shown in the image starts running at this time. Figure 2 The processor 1011 shown controls the LED pin to be high, turning off the light-emitting diode D1; controls the Control pin to be high, turning on the transistor Q1; and outputs a low level on the P-OUT pin. Figure 4The / CLR pin of the D flip-flop shown is in a reset state affected by a reset circuit composed of resistor R7 and capacitor C3, at this time the output pin BAT-Ctl of the D flip-flop outputs low by default, and the Figure 3 The key K1 shown is invalid at this time Figure 5 The triode Q3 and the triode Q4 shown are both in the off state, so the output voltage VCC-OUT of the programmable key switch power supply circuit is 0.
[0028] When the processor 1011 needs to input the data collected by the external data collection device, the external device needs to be powered, at this time Figure 2 The processor 1011 shown controls the LED pin to be low, lighting the light-emitting diode D1, and controls the Control pin of the processor 1011 to be low, so that the triode Q1 is cut off, and then the P-OUT pin outputs high. When the staff sees that the light-emitting diode D1 is lit, press the Figure 3 The key K1 shown, so that the rising edge of the PWCLK pin is generated and input to Figure 4 The CLK pin of the D flip-flop shown, so that the output BAT-Ctl of the D flip-flop follows the P-OUT pin to output high, so that Figure 5 The triode Q3 and the triode Q4 shown are both in the on state, so the output voltage VCC-OUT of the programmable key switch power supply circuit is equal to VCC, thereby meeting the power supply requirement of the external data collection device.
