[0045] In some embodiments, such as Figure 7 As shown, the PA1 / OSC IN pin and PA2 / OSC OUT pin of the main control unit are respectively connected to a switch driver unit (OUT_9 and OUT_10).

[0046] Taking the switch driver unit (OUT_9) as an example, the switch driver unit (OUT_9) includes a switching diode D209 and a switching transistor Q209. The input control signal terminal of the switching transistor Q209 is connected to a resistor R225 and then to the PA1 / OSC IN pin of the main control unit.

Among them, OUT_1-OUT_8 and OUT_13-OUT_20 are extended channels through the display driver chip, and OUT_9-OUT_12 are directly or indirectly connected to the main control unit, adapting to multi-device collaborative control scenarios.

[0050] In some embodiments, such as Figure 9 As shown, the current control unit includes a first transistor Q401, a second transistor Q402, and a third transistor Q403. The emitter of the first transistor Q401 is connected to a 25V power supply; the collector of the first transistor Q401 is connected to a resistor R401 and then grounded; the base of the first transistor Q401 is connected to the collector of the third transistor Q403, and the base of the first transistor Q401 is also connected to resistors R403 and R404 in sequence and then grounded. The emitter of the second transistor Q402 is connected to a resistor R402 and then to a 25V power supply; the collector of the second transistor Q402 is connected to an adjustable resistor PTC401 and then outputs a 24V power supply, which powers the aforementioned switch drive unit; the base of the second transistor Q402 is connected to a resistor R401 and then grounded.

[0051] The current control unit is connected to a 25V power supply. Through the conduction and cutoff characteristics of the transistor and the adjustment function of the adjustable resistor, the input voltage is stably converted to a 24V output to provide a stable power supply for the switching drive unit. It can dynamically adapt to load changes, avoid malfunctions or damage to the drive module caused by voltage fluctuations, extend the service life of the controller and external equipment, and improve control accuracy.

[0052] In some embodiments, such as Figure 10 As shown, the PD2 / AIN3 / TIM2 CC3 pin and PD3 / AIN47ADC ETR pin of the main control unit are connected to the detection unit. The detection unit includes a first comparator U501A. The output of the first comparator U501A is connected to the PD2 / AIN3 / TIM2 CC3 pin of the main control unit. The output of the first comparator U501A is also connected to a resistor R506 and then to a 5V power supply. The power supply terminal of the first comparator U501A is connected to a 5V power supply, and the ground terminal of the first comparator U501A is grounded. The non-inverting input terminal of the first comparator U501A is connected to a capacitor C112 and then to ground. The non-inverting input terminal of the first comparator U501A is also connected to a resistor R508 and then to ground. Resistor R508 is also connected to a resistor R505 and then to ground. The inverting input terminal of the first comparator U501A is connected to a resistor R502 and then to ground, and also connected to a resistor R501 and then to a 5V power supply.

[0053] In some embodiments, the detection unit further includes a second comparator U501B, the output of which is connected to the PD3 / AIN47ADC of the main control unit. The ETR pin is connected to the output of the second comparator U501B, which is also connected to a 5V power supply via a resistor R507. The non-inverting input of the second comparator U501B is connected to ground via a capacitor C112, and also to ground via a resistor R508. Resistor R508 is further connected to ground via a resistor R505. The inverting input of the second comparator U501B is connected to a 5V power supply via a resistor R503. The inverting input of the second comparator U501B is connected to ground via a resistor R504. A resistor R500 is connected between resistors R504 and R505. When R501 is 51KΩ, it is the critical point for a 0.6A alarm. R503 is 100KΩ, and the load is a relay, which can be considered as a non-circuit short-circuit detection and open-circuit detection unit.

[0054] The detection unit identifies abnormal operating conditions such as short circuits and open circuits in real time by detecting changes in current and voltage in the detection circuit. When an abnormality is detected, it quickly sends a fault signal to the main control unit, providing a trigger basis for subsequent emergency handling such as alarms and shutdowns, and reducing the losses caused by the expansion of the fault. The accurate fault threshold judgment is achieved by setting the resistance parameter (e.g., R501=51K corresponds to 0.6A alarm).

[0055] In some embodiments, such as Figure 11 As shown, the switch indicator unit is connected to the main control unit. The switch indicator unit includes an optocoupler U203. The input terminal of the optocoupler U203 is connected to two resistors (R107 and R106) and then connected to a 5V power supply. Resistor R106 is also connected in parallel with a LEN lamp D101. The LEN lamp D101 is also connected to a switch SW101 and then grounded. The output terminal of the optocoupler U203 is also connected to a resistor R292 and then grounded. The other two interfaces of the optocoupler U203 are directly grounded. The output terminal of the optocoupler U203 is also connected to two parallel resistors (R290 and R291) and then connected to the main control unit.

[0056] The switch indicator unit controls the mode switching and status indication module. It controls the conduction state of the optocoupler via a switch to achieve the switching of specific control modes; the LEN light synchronously indicates the switch status. The optocoupler transmits the switching signal to the main control unit in isolation, ensuring the safety and reliability of signal transmission, while allowing the user to intuitively understand the current control mode.

[0057] like Figure 12As shown, the PA3 / SPI NSS pin of the main control unit is connected to a control button K101, and then grounded after being connected to a resistor R102. The control button provides a manual operation interface, which can realize functions such as circuit start / stop, parameter setting, and mode switching, meeting the needs of manual intervention control;

[0058] like Figure 13 As shown, the PC7 / SPI MISO pin of the main control unit is connected to a resistor R105 and a transistor Q101, which in turn connects to a buzzer BL101. The buzzer, driven by the transistor, is activated upon receiving a fault signal from the main control unit, promptly alerting the user to equipment malfunctions and improving fault response timeliness.

[0059] Therefore, this application discloses a pulse controller. The main control unit coordinates signal transmission and command execution, while the communication unit enables stable signal interaction with external devices, ensuring accurate transmission of control commands and improving the reliability of device coordination. A digital display unit presents the current, voltage, and operating status of external devices in real time, allowing users to intuitively monitor operating parameters, promptly detect anomalies, and reduce maintenance difficulty. The switch drive unit efficiently drives the external devices on and off, responding quickly to meet the immediacy requirements of pulse control. The current control unit precisely regulates the input voltage of the switch drive unit, ensuring stable power supply to the drive circuit, avoiding equipment malfunctions or damage caused by voltage fluctuations, and extending the service life of the pulse controller and external devices. This approach balances control accuracy and operational stability, effectively solving problems such as signal transmission lag, inconvenient parameter monitoring, and unstable power supply in traditional controllers, thus improving the overall efficiency and reliability of pulse control.
