Description

Technical Field

[0001] The present application relates to the technical field of electronic circuits, and particularly to a device for implementing different trigger modes with a single port. Background Art

[0002] With the advancement of intelligent manufacturing, the safety operation of domestic construction machinery has been taken seriously, and the requirements for safety control, error prevention, and miniaturization have gradually increased. The improvement of electronic components in the safety control of mechanical equipment has become the key to the research and development of electrical control components.

[0003] When the equipment is running, it is extremely important whether the safety electrical system can ensure safety in case of faults or misoperations. The traditional trigger (reset) circuit starts the equipment by pressing the trigger button. When the safety input circuit is closed, the function of the trigger button is short-circuited or there is a short-circuit fault.

[0004] However, there are many limitations in the triggering methods of traditional logic electrical components. The multi-port control method increases the number of control ports, which is not conducive to miniaturization design; the software control logic depends on the microcontroller for triggering, the requirements for human-machine operation are increased, the cost is difficult to control, and the software safety certification is complex, making safety assessment and certification difficult, and the popularization and promotion are blocked.

At the same time, the term "and / or" used in this specification includes any and all combinations of the related listed items.

[0084] In an exemplary embodiment, as Figure 1As shown in the figure, the present application provides a device for implementing different trigger modes with a single port. The device includes a signal generation module 2 and a multi-mode trigger control module 4. The power supply output terminal of the signal generation module 2 is used to connect to a power supply voltage. The signal generation module 2 is used to support the output of a power supply signal and multiple trigger signals. The power supply terminal of the multi-mode trigger control module 4 is connected to the power supply output terminal of the signal generation module 2. The single-signal trigger terminal of the multi-mode trigger control module 4 is connected to the trigger signal output terminal of the signal generation module 2. The multi-mode trigger control module 4 is used to receive the power supply signal and the trigger signal, and when the trigger signal meets the preset trigger condition corresponding to the trigger signal, it outputs a working enable signal to the subsequent electrical equipment.

[0085] Among them, the types of trigger signals can refer to different forms or modes of electrical signals output by the signal generation module 2. These signals may differ in waveform, frequency, duration, voltage level, pulse width, etc. Different types of trigger signals can be used to represent different operation instructions or status information. For example, it can include: edge trigger: triggered when the signal changes from low to high (rising edge) or from high to low (falling edge); level trigger: triggered when the signal remains at a certain specific voltage level (high level or low level); pulse trigger: triggered by a voltage or current pulse within a short period of time. The preset trigger condition can refer to the rules or criteria preset in the multi-mode trigger control module 4 for determining whether the received trigger signal meets a certain type of definition, so as to decide whether to output a working enable signal; the preset trigger condition can also refer to the conduction condition of the hardware circuit in the multi-mode trigger control module 4 for verifying whether the received trigger signal meets the conduction condition of the hardware circuit in the multi-mode trigger control module 4, so as to decide whether to output a working enable signal. Each trigger signal has a corresponding preset trigger condition. Only when the actually received trigger signal meets these conditions, the multi-mode trigger control module 4 will consider this to be a valid trigger and execute the corresponding action. Taking the edge trigger as an example, the preset trigger condition can include the regulation of the time point when the rising edge or falling edge appears. In some applications, it can refer to the relative timing relationship between the power supply signal and the edge trigger signal. For example, when the power supply signal and the edge trigger signal arrive in a certain order in sequence, and the time difference between the two should be maintained within a certain range to constitute a valid edge trigger.

[0086] Exemplarily, under the action of the power supply voltage, the signal generation module 2 can output a power supply signal and a variety of trigger signals. These trigger signals differ in terms of waveform, frequency, duration, voltage level, etc., such as edge trigger, level trigger, pulse trigger, etc. The power supply terminal of the multi-mode trigger control module 4 is connected to the power supply output terminal of the signal generation module 2, and its single-signal trigger terminal receives the trigger signal. The multi-mode trigger control module 4 has corresponding preset trigger conditions for different trigger signals according to the preset rules, or has corresponding circuit conduction conditions for different trigger signals according to the pre-designed circuit. For example, for edge trigger, it is necessary to judge the occurrence time point of the rising edge or falling edge, including the relative timing relationship and time difference range between the power supply signal and the edge trigger signal; for level trigger, the signal needs to be maintained at a specific level for at least a minimum time, etc. When the received trigger signal meets the preset trigger conditions of its corresponding type, the multi-mode trigger control module 4 will output a working enable signal to the subsequent power-consuming device, thereby realizing the different trigger mode functions of a single port.

[0087] In this embodiment, by integrating the signal generation module and the multi-mode trigger control module, a single port with multiple trigger modes is realized with a simple circuit design. When the number of control ports is limited, there is no need to set multiple ports for different trigger modes, and only one port can meet multiple trigger requirements, effectively saving hardware resources. Moreover, the circuit structure is relatively simple, without complex and expensive multi-port control circuits and related supporting facilities, reducing the investment in hardware costs. At the same time, the multi-mode trigger control module can automatically identify and process trigger signals according to preset rules or circuits, reducing the requirements for the technical level of operators, greatly improving the practicability and economy of the system, and providing an efficient, convenient and economical solution for the trigger control of related devices or systems.

[0088] In an exemplary embodiment, the signal generation module 2 is used to support the output of at least two of the following trigger signals: high-level enable trigger signal, low-level enable trigger signal, rising-edge trigger signal, falling-edge trigger signal, square-wave trigger signal.

[0089] Among them, the trigger signals may specifically include a high-level enable trigger signal, a low-level enable trigger signal, a rising-edge trigger signal, a falling-edge trigger signal, and a square-wave trigger signal.

[0090] Exemplarily, the signal generation module 2 can support the output of multiple trigger signals, such as at least two of high-level enable, low-level enable, rising edge, falling edge, and square wave trigger signals, greatly enriching the diversity of trigger signal selection. It can meet the different requirements of different backend electrical equipment or complex systems for the trigger mechanism under various working conditions and functional requirements, and greatly expand the applicability of the entire device. For example, in some circuits sensitive to level, high-level or low-level enable trigger signals can be used to accurately control. In circuits related to sequential logic, rising edge or falling edge trigger signals can effectively achieve state switching and synchronization. Square wave trigger signals can be used for the drive of periodic actions, thus effectively adapting to multiple devices and systems in a flexible and variable trigger manner, and improving the overall performance and compatibility of the system.

[0091] In an exemplary embodiment, as Figure 2 shown, when the signal generation module 2 supports the output of high-level enable trigger signals, the multi-mode trigger control module 4 includes a first trigger unit 41 and a switch unit 42. The single-signal trigger terminal of the first trigger unit 41 is connected to the trigger signal output terminal of the signal generation module 2; the input terminal of the switch unit 42 is connected to the power supply output terminal of the signal generation module 2, and the controlled terminal of the switch unit 42 is connected to the control terminal of the first trigger unit 41; the first trigger unit 41 is used to control the switch unit 42 to conduct when receiving a high-level enable trigger signal.

[0092] Exemplarily, since there is no requirement for the output timing of high-level trigger signals during the actual application process, when the multi-mode trigger control module 4 receives a high-level trigger signal, it can be considered that the high-level trigger signal meets the trigger condition. At this time, the first trigger unit 41 in the multi-mode trigger control module 4 will automatically identify and receive the high-level trigger signal, and under the action of the high-level enable trigger signal, control the switch unit 42 to conduct, so that the power supply voltage output from the power supply output terminal of the signal generation module 2 is used as a working enable signal and output to the backend electrical equipment through the switch unit 42.

[0093] In this embodiment, by introducing the first trigger unit and the switch unit, a direct response mechanism for high-level enable trigger signals is achieved. When the signal generation module outputs a high-level enable trigger signal, the multi-mode trigger control module can immediately recognize and respond without considering the specific timing or additional conditions of the trigger signal, simplifying the trigger logic and improving the response speed and reliability of the system. Specifically, once the high-level trigger signal is received, the first trigger unit immediately controls the switch unit to conduct, enabling the supply voltage to be directly transmitted as a working enable signal to the subsequent electrical devices. This not only reduces the complexity of signal processing but also ensures a fast and stable power supply, enhancing the flexibility and practicality of the system, and is particularly suitable for application scenarios that require immediate response. In addition, since it does not rely on complex timing control, this solution also reduces the design and maintenance costs and improves the usability and stability of the overall system.

[0094] In an exemplary embodiment, as Figure 2 shown, the first trigger unit 41 includes a diode VD3, a capacitor C1, a resistor R5, and a resistor R6. The anode of the diode VD3 is connected to the trigger signal output terminal of the signal generation module 2; the first end of the capacitor C1 is connected to the cathode of the diode VD3; the first end of the resistor R5 is connected to the second end of the capacitor C1, and the second end of the resistor R5 is grounded; the first end of the resistor R6 is connected to the first end of the capacitor C1, and the second end of the resistor R6 is connected to the controlled end of the switch unit 42.

[0095] Exemplarily, when the signal generation module 2 outputs a high-level trigger signal, this signal charges the capacitor C1 through the diode VD3, and at the same time outputs a control signal through the resistor R6 to the controlled end of the switch unit 42 to make the switch unit 42 conduct, so that the supply signal output by the signal generation module 2 is used as a working enable signal and is output to the subsequent electrical devices through the switch unit 42. In some embodiments, a diode VD2 is also provided between the anode of the triode VD3 and the trigger signal output terminal of the signal generation module 2 to prevent the reverse transmission of signals.

[0096] In this embodiment, the first trigger unit composed of diode VD3, capacitor C1, resistor R5 and resistor R6 is used to effectively process and convert the high-level trigger signal. Diode VD3 can effectively prevent current backflow, protect circuit components, and ensure that the signal is transmitted unidirectionally to capacitor C1. Capacitor C1 is charged under the action of the high-level trigger signal, which plays the role of energy storage and smoothing signal, reduces the impact of signal fluctuations on subsequent circuits, and improves the stability and reliability of the signal. Resistor R5 and capacitor C1 can adjust the charging time constant and accurately control the timing of signal processing, while resistor R6 reasonably transmits the processed signal to the controlled end of the switch unit, so that the switch unit can be turned on under the appropriate signal drive, and smoothly converts the power supply voltage of the signal generation module into a work enable signal output to the back-end electrical equipment. The overall circuit structure is simple and compact, and the cost is low. While realizing the high-level trigger function, the efficient and stable operation of the system is guaranteed.

[0097] In an exemplary embodiment, Figure 2 As shown, the multi-mode trigger control module 4 further includes a first latch unit 43 . A controlled end of the first latch unit 43 is connected to a control end of the first trigger unit 41 , and an output end of the first latch unit 43 is connected to a controlled end of the switch unit 42 .

[0098] Exemplarily, when the first trigger unit 41 receives a high-level trigger signal and generates a corresponding control signal, the first latch unit 43 can latch the instantaneous control signal state. For example, in some complex circuit environments, there may be short-term interference or signal jitter. If there is no latch unit, these unstable factors may cause abnormal fluctuations in the controlled end signal of the switch unit 42, thereby affecting the normal conduction state of the switch unit 42. The first latch unit 43 can lock the effective control signal to ensure that the switch unit 42 can continue to stably maintain the proper conduction state, and ensure that the power supply voltage can be stably output to the back-end power-consuming equipment as a work enable signal.

[0099] In this embodiment, the first latch unit is introduced to ensure that the controlled end of the switch unit can maintain a stable conduction state even in the case of short-term interference or signal jitter in a complex circuit environment. Abnormal fluctuations caused by external unstable factors are effectively avoided, ensuring that the power supply voltage can be continuously and stably output as a work enable signal to the back-end power-consuming equipment.

[0100] In an exemplary embodiment, Figure 2As shown, the first latching unit 43 includes a capacitor C3, a diode VD4, a triode Q3, a triode Q4, a resistor R7, and a resistor R8. The first end of the capacitor C3 is connected to the control end of the first triggering unit 41, and the second end of the capacitor C3 is grounded; the anode of the diode VD4 is connected to the first end of the capacitor C3; the base of the triode Q3 is connected to the cathode of the diode VD4, and the emitter of the triode Q3 is grounded; the collector of the triode Q4 is connected to the base of the triode Q3, and the base of the triode Q4 is connected to the collector of the triode Q3; the first end of the resistor R7 is connected to the emitter of the triode Q4, and the second end of the resistor R7 is connected to the controlled end of the switching unit 42; the first end of the resistor R8 is connected to the base of the triode Q4, and the second end of the resistor R8 is connected to the second end of the resistor R7.

[0101] Exemplarily, the electrical signal output by the first triggering unit 41 charges the capacitor C3 and at the same time is output to the base of the triode Q3 through the diode VD4 to turn on the triode Q3. When the triode Q3 is turned on, the potential of the controlled end of the switching unit 42 and the potential of the base of the triode Q4 are pulled low. Since the input end of the switching unit 42 is connected to the power supply output end of the signal generation module 2, the input end of the switching unit 42 is turned on under the action of the power supply voltage at this time, so that the power supply voltage output by the signal generation module 2 is converted into a working enable signal and output to the subsequent power-consuming device. At the same time, when the switching unit 42 is turned on, the potential of the emitter of the triode Q4 is greater than the potential of its base, and the triode Q4 is turned on, resulting in the potential of the base of the triode Q3 being continuously pulled high, so that the potential of the base of the triode Q3 is always greater than the potential of its emitter when the switching unit 42 is turned on, so that the triode Q3 is always turned on, and further the switching unit 42 remains turned on after the first turn-on.

[0102] In this embodiment, through the first latching unit composed of the capacitor C3, the diode VD4, the triode Q3, the triode Q4, the resistor R7, and the resistor R8, the capacitor C3 and the diode VD4 cooperate to process the electrical signal output by the first triggering unit and transmit it to the base of the triode Q3 to control its conduction. On this basis, by using the connection between the triodes Q3 and Q4 and the functions of the resistors R7 and R8, it is realized that after the first turn-on of the switching unit, the triode Q3 can always be turned on, and further the switching unit can be continuously kept turned on, so that the power supply voltage output by the signal generation module can be stably and reliably converted into a working enable signal and output to the subsequent power-consuming device, avoiding the accidental disconnection of the switching unit caused by external interference, signal fluctuations and other factors, ensuring the continuity and stability of the operation of the subsequent power-consuming device. At the same time, the circuit structure is relatively simple, taking into account the cost control and high-efficiency operation requirements while realizing the latching function.

[0103] In an exemplary embodiment, as Figure 3As shown, when the signal generation module 2 supports the output of a rising-edge trigger signal, the multi-mode trigger control module 4 further includes a timing monitoring unit 44. The first power supply terminal and the second power supply terminal of the timing monitoring unit 44 are both connected to the power supply output terminal of the signal generation module 2. The input terminal of the timing monitoring unit 44 is connected to the trigger signal output terminal of the signal generation module 2, and the output terminal of the timing monitoring unit 44 is connected to the controlled terminal of the first latch unit 43. The timing monitoring unit 44 is configured to prohibit the output of a turn-off signal to the first latch unit 43 when the output time of the power supply signal is earlier than the output time of the rising-edge trigger signal, so that the first latch unit 43 is turned on under the drive of the first trigger unit 41.

[0104] Exemplarily, when the power supply signal of the signal generation module 2 and the rising-edge trigger signal are output simultaneously, the timing monitoring unit 44 will receive the power supply signal and the rising-edge trigger signal at the same time. At this time, the timing monitoring unit 44 will determine that the timing of the rising-edge trigger signal is incorrect, that is, it is determined that the rising-edge trigger signal is an invalid rising-edge trigger signal, and thus output a turn-off signal to the first latch unit 43, so that the first latch unit 43 is kept off under the driving action of the timing monitoring unit 44, and further the switch unit 42 is kept off. At this time, no working enable signal is output to the backend electrical device. When the rising-edge trigger signal is output earlier than the power supply signal, the timing monitoring unit 44 will also determine that the timing of the rising-edge trigger signal is incorrect, and will also determine that the rising-edge trigger signal is an invalid rising-edge trigger signal, and output a turn-off signal to the first latch unit 43, so that the first latch unit 43 is kept off under the driving action of the timing monitoring unit 44. When the output time of the power supply signal is earlier than the output time of the rising-edge trigger signal, the timing monitoring unit 44 determines that the timing of the rising-edge trigger signal is correct and determines that the rising-edge trigger signal is a valid rising-edge trigger signal. At this time, the timing monitoring unit 44 will not output a turn-off signal to the first latch unit 43, so that the first latch unit 43 is kept on under the drive of the first trigger unit 41. Thus, under the action of the rising-edge trigger signal, the power supply signal can be output as a working enable signal to the backend electrical device through the switch unit 42.

[0105] In this embodiment, by adding a timing monitoring unit to accurately monitor and judge the output moments of the power supply signal and the rising-edge trigger signal, the timing relationship of the signals is effectively regulated. It is ensured that only when the output moment of the power supply signal is earlier than the output moment of the rising-edge trigger signal, that is, when the timing of the rising-edge trigger signal is correct, the first latch unit is allowed to conduct under the drive of the first trigger unit, so that the working enable signal can be normally output to the subsequent power-consuming device. In the case of incorrect timing, such as when the power supply signal and the rising-edge trigger signal are output simultaneously or the rising-edge trigger signal is output earlier than the power supply signal, a shutdown signal can be output in time to cut off the first latch unit, avoiding mis-triggering caused by incorrect timing and abnormal output of the working enable signal, greatly improving the accuracy, reliability, and stability of the entire device when operating in the rising-edge trigger mode, and ensuring that the subsequent power-consuming device can work orderly according to the correct trigger logic.

[0106] In an exemplary embodiment, as Figure 3 shown, the timing monitoring unit 44 includes a charging unit 442 and a second latch unit 444. The power supply terminal of the charging unit 442 is connected to the power supply output terminal of the signal generation module 2, and the input terminal of the charging unit 442 is connected to the trigger signal output terminal of the signal generation module 2; the power supply terminal of the second latch unit 444 is connected to the power supply output terminal of the signal generation module 2, the input terminal of the second latch unit 444 is connected to the output terminal of the charging unit 442, and the output terminal of the second latch unit 444 is connected to the controlled terminal of the first latch unit 43.

[0107] Among them, the charging unit 442 is used to judge whether the timing between the power supply signal and the rising-edge trigger signal is correct based on the charging time.

[0108] Exemplarily, the power supply signal is used to charge the charging unit 442. The charging unit 442 can calculate the cumulative charging duration with the time node when the power supply signal is received as the starting point of timing. If the charging unit 442 receives the rising-edge trigger signal before the cumulative charging duration reaches the preset charging duration, the charging unit 442 will control the second latch unit 444 to conduct, so that the second latch unit 444 outputs a shutdown signal to the first latch unit 43 under the power supply action of the power supply signal, thereby controlling the switch unit 42 to remain cut off. If the charging unit 442 receives the rising-edge trigger signal after the cumulative charging duration reaches the preset charging duration, the charging unit 442 will control the second latch unit 444 to cut off, so that the second latch unit 444 cannot output a shutdown signal to the first latch unit 43, so that the conduction signal output by the first trigger unit 41 when receiving the rising-edge trigger signal can make the first latch unit 43 conduct, thereby controlling the conduction of the switch unit 42.

[0109] Specifically, when the output time of the power supply signal is the same as that of the rising edge trigger signal, the power supply signal and the rising edge trigger signal act on the charging unit 442 simultaneously; when the output time of the power supply signal is later than that of the rising edge trigger signal, the power supply signal acts on the charging unit 442 later than the rising edge trigger signal. Obviously, in the above two cases, the rising edge trigger signal always acts on the charging unit 442 earlier than or simultaneously with the power supply signal, that is, the charging unit 442 will receive the rising edge trigger signal before the cumulative charging duration reaches the preset charging duration. As a result, the charging unit 442 outputs a conduction signal to the second latching unit 444 to drive the second latching unit 444 to conduct, so that the second latching unit 444 outputs a turn-off signal to the first latching unit 43, causing the first latching unit 43 to remain cut-off, and further causing the switching unit 42 to remain cut-off. When the output time of the power supply signal is earlier than that of the rising edge trigger signal, the power supply signal acts on the charging unit 442 earlier than the rising edge trigger signal, that is, the charging unit 442 receives the rising edge trigger signal after the cumulative charging duration reaches the preset charging duration. At this time, the charging unit 442 does not output a conduction signal to the second latching unit 444, causing the second latching unit 444 to be cut-off and unable to output a turn-off signal to the first latching unit 43. Thus, the conduction signal output by the first trigger unit 41 when receiving the rising edge trigger signal can cause the first latching unit 43 to conduct, and further control the conduction of the switching unit 42. Based on the mutual cooperation between the charging unit 442 and the control unit, the timing of the rising edge trigger signal can be identified, so as to achieve outputting a conduction signal to the switching unit 42 only when the rising edge trigger timing is correct, and outputting a working enable signal to the backend electrical device to complete the rising edge trigger.

[0110] In this embodiment, through the mutual cooperation of the charging unit and the second latching unit in the timing monitoring unit, the accurate identification of the rising edge trigger signal timing is achieved. The charging unit charges and times based on the power supply signal, and controls the conduction or cut-off state of the second latching unit according to the relationship between the received rising edge trigger signal and the preset charging duration, and further controls the states of the first latching unit and the switching unit. Based on this, it can be ensured that a conduction signal is output to the switching unit only when the rising edge trigger timing is correct, and a working enable signal is output to the backend electrical device, effectively avoiding misoperations caused by timing errors and improving the stability and reliability of the system.

[0111] In an exemplary embodiment, such as Figure 3As shown, the charging unit 442 includes a capacitor C2, a resistor R9, a resistor R10, a triode Q5, and a triode Q6. The first end of the capacitor C2 is connected to the power supply output end of the signal generation module 2; the first end of the resistor R9 is connected to the second end of the capacitor C2, and the second end of the resistor R9 is grounded; the first end of the resistor R10 is connected to the second end of the capacitor C2; the base of the triode Q5 is connected to the second end of the resistor R10, and the emitter of the triode Q5 is grounded; the base of the triode Q6 is connected to the collector of the triode Q5, the emitter of the triode Q6 is connected to the trigger signal output end of the signal generation module 2, and the collector of the triode Q6 is connected to the input end of the second latching unit 444.

[0112] Exemplarily, as Figure 4 shown, X1 represents a power supply signal, X2 represents a rising-edge trigger signal, and Y1 represents a working enable signal. When the power supply signal X1 and the rising-edge trigger signal X2 are output from the signal generation module 2 to the charging unit 442 at the same time, the power supply signal X1 starts to charge the capacitor C2. The triode Q5 conducts during the charging process of the capacitor C2, and the base potential of the triode Q6 is pulled low. Since the emitter of the triode Q6 is connected to the rising-edge trigger signal X2, the triode Q6 conducts and outputs a conduction signal to the second latching unit 444 to drive the second latching unit 444 to output a turn-off signal to the first latching unit 43, so that the first latching unit 43 is turned off, and thus the switching unit 42 is turned off and no working enable signal Y1 is output. When the power supply signal X1 is output from the signal generation module 2 to the charging unit 442 earlier than the rising-edge trigger signal X2, the capacitor C2 is charged under the action of the previously input power supply signal X1, that is, before the rising-edge trigger signal X2 is received at the emitter of the triode Q6, the capacitor C2 is fully charged, and the base of the triode Q5 will remain at a low level after the capacitor C2 is fully charged, that is, the triode Q5 is in a cut-off state. At this time, since the triode Q5 is in a cut-off state, even if the rising-edge trigger signal X2 is received at the emitter of the triode Q6, the triode Q6 cannot conduct, that is, no conduction signal can be output to the second latching unit 444, and the second latching unit 444 cannot output a turn-off signal to the first latching unit 43. As a result, the conduction signal output by the first trigger unit 41 when receiving the rising-edge trigger signal X2 can turn on the first latching unit 43, and then control the conduction of the switching unit 42 to output a working enable signal Y1. In this embodiment, the charging duration when the capacitor C2 is fully charged can be changed by changing the capacitance value of the capacitor C2, so as to change the preset charging duration, and further adapt to the settings with different timing recognition accuracy requirements.

[0113] In this embodiment, through the combination and mutual cooperation of components such as capacitor C2, resistor R9, resistor R10, triode Q5, and triode Q6, the states of subsequent units can be accurately controlled according to the output sequence of the power supply signal and the rising-edge trigger signal, effectively avoiding mis-triggering caused by incorrect timing situations such as the simultaneous output of the two or the premature output of the rising-edge trigger signal, and ensuring the accurate output of the working enable signal. At the same time, by virtue of the characteristic that the charging duration can be flexibly adjusted by changing the capacitance value of capacitor C2, and then changing the preset charging duration, it can well adapt to various application scenarios with different timing recognition accuracy requirements, enhancing the adaptability and flexibility of the entire device in the rising-edge trigger mode to different working conditions, and improving the reliability, accuracy, overall practicality, and compatibility of the system operation.

[0114] In an exemplary embodiment, as Figure 3 shown, the second latch unit 444 includes resistor R11, triode Q7, triode Q8, resistor R12, and resistor R13. The first end of resistor R11 is connected to the output end of the charging unit 442; the collector of triode Q7 is connected to the second end of resistor R11; the base of triode Q8 is connected to the collector of triode Q7, the collector of triode Q8 is respectively connected to the base of triode Q7 and the controlled end of the first latch unit 43, and the emitter of triode Q8 is grounded; the first end of resistor R12 is connected to the emitter of triode Q7, and the second end of resistor R12 is connected to the power supply output end of the signal generation module 2; the first end of resistor R13 is connected to the power supply output end of the signal generation module 2, and the second end of resistor R13 is connected to the collector of triode Q8.

[0115] Exemplarily, when the conduction signal output by the charging unit 442 is input to the base of triode Q8 through resistor R11, triode Q8 conducts, and the base potential of triode Q7 is pulled down. Since the emitter of triode Q7 is connected to the power supply signal through resistor R12, therefore, triode Q7 conducts under the action of the power supply signal, and triode Q8 completes self-locking through triode Q7. Also, since the controlled end of the first latch unit 43 is connected to the collector of triode Q8, therefore, when triode Q8 is conducting, the potential of the controlled end of the first latch unit 43 is also forced to be pulled down, that is, a turn-off signal is output to the controlled end of the first latch unit 43. In the above situation, even if the first trigger unit 41 outputs a conduction signal to the controlled end of the first latch unit 43 under the action of the rising-edge trigger unit, the first latch unit 43 cannot conduct and remains in the off state, so that the switch unit 42 also cannot conduct, that is, a working enable signal cannot be output to the subsequent electrical equipment. When the charging unit 442 cannot output a conduction signal to the second latch unit 444, triode Q7 and triode Q8 naturally cannot conduct, and the potential of the controlled end of the first latch unit 43 will not be forced to be pulled down, that is, a turn-off signal cannot be output to the controlled end of the first latch unit 43.

[0116] In this embodiment, through the second latching unit composed of resistor R11, triode Q7, triode Q8, resistor R12, and resistor R13, when the charging unit outputs a conduction signal, self-locking is achieved through the interaction between internal triodes, and a turn-off signal is reliably output to the first latching unit, effectively preventing mis-triggering caused by situations such as non-compliance with the trigger timing, ensuring that the switching unit does not conduct erroneously, and avoiding the mis-output of the operation enable signal to the subsequent power-consuming device, thus guaranteeing the accuracy and stability of the entire trigger mechanism; and when the charging unit has no corresponding output, it will not interfere with the normal potential and conduction logic of the first latching unit. This orderly and precise control mechanism improves the overall reliability and operation accuracy of the device in response to different signal situations, enabling the system to perform trigger operations according to the correct logic.

[0117] In an exemplary embodiment, when the signal generation module 2 supports the output of a falling-edge trigger signal or a square-wave trigger signal, the multi-mode trigger control module 4 further includes a clamping unit 45. The input end of the clamping unit 45 is connected to the trigger signal output end of the signal generation module, and the output end of the clamping unit 45 is connected to the controlled end of the first latching unit 43, for providing a clamping voltage to the first latching unit 43.

[0118] Exemplarily, when the signal generation module 2 supports the output of a falling-edge trigger signal, the circuit structure diagram of the multi-mode trigger control module 4 is as Figure 5 shown. The specific implementation process takes the timing diagram as shown in Figure 6 as an example. Among them, X1 is the power supply signal, X2 is the falling-edge trigger signal, and Y1 is the operation enable signal. When the trigger signal generation module 2 outputs the falling-edge trigger signal X2, the falling-edge trigger signal X2 is simultaneously input to the first trigger unit 41 and the clamping unit 45. During the high-level stage of the falling-edge trigger signal X2, the capacitor C1 of the first trigger unit 41 is in a charging state, while the clamping unit 45 controls the voltage of the controlled end of the first latching unit 43 at the clamping voltage, so that the first latching unit 43 cannot conduct, and thus the switching unit 42 is cut off, and at this time, no operation enable signal Y1 is output. At the falling edge of the falling-edge trigger signal X2, the clamping unit 45 and the first trigger unit 41 lose power simultaneously. The clamping unit 45 can no longer provide the clamping voltage to the first latching unit 43, and the capacitor C1 in the first trigger unit 41, due to being charged during the high-level stage of the falling-edge trigger signal X2, can control the first latching unit 43 to conduct when the first trigger unit 41 loses power, thereby driving the switching unit 42 to conduct to output the operation enable signal.

[0119] When the signal generation module 2 supports the output of a square-wave trigger signal, the circuit structure diagram of the multi-mode trigger control module 4 is as Figure 7As shown. The specific implementation process takes the timing diagram as shown in Figure 8 as an example. Among them, X1 is the power supply signal, X2 is the square wave trigger signal, and Y1 is the working enable signal. When the trigger signal generation module 2 outputs the power supply signal X1 and the square wave trigger signal X2 at the same time, the timing monitoring unit 44 will receive the power supply signal X1 and the square wave trigger signal X2 at the same time. At this time, the timing monitoring unit 44 will determine that the timing of the square wave trigger signal X2 is incorrect, that is, it is determined that the square wave trigger signal X2 is an invalid square wave trigger signal X2, and then output a shutdown signal to the first latch unit 43, so that the first latch unit 43 remains cut-off under the driving action of the timing monitoring unit 44, and further makes the switch unit 42 remain cut-off. At this time, no working enable signal is output to the backend electrical equipment. When the square wave trigger signal X2 is output earlier than the power supply signal X1, the timing monitoring unit 44 will also determine that the timing of the square wave trigger signal X2 is incorrect, and will also determine that the square wave trigger signal X2 is an invalid square wave trigger signal X2, and output a shutdown signal to the first latch unit 43, so that the first latch unit 43 remains cut-off under the driving action of the timing monitoring unit 44.

[0120] When the output time of the power supply signal X1 is earlier than the output time of the square wave trigger signal X2, the timing monitoring unit 44 determines that the timing of the square wave trigger signal X2 is correct, and determines that the square wave trigger signal X2 is a valid square wave trigger signal X2. At this time, the timing monitoring unit 44 will not output a shutdown signal to the first latch unit 43, so that the first latch unit 43 can be turned on under the drive of the first trigger unit 41. Among them, in this case, when the square wave trigger signal X2 is input to the first trigger unit 41, the capacitor C1 in the first trigger unit 41 is in a charging state during the high-level stage of the square wave trigger signal X2. And due to the existence of the clamping unit 45, the clamping unit 45 will clamp the potential of the controlled end of the first latch unit 43 to the clamping voltage during the high-level stage of the square wave trigger signal, so that the first latch unit 43 cannot be turned on during the high-level stage of the square wave trigger signal. At the falling edge of the square wave trigger signal X2, the clamping unit 45 and the first trigger unit 41 lose power at the same time. The clamping unit 45 cannot continue to provide the clamping voltage to the first latch unit 43, and the capacitor C1 in the first trigger unit 41 is charged during the high-level stage of the square wave trigger signal X2. When the first trigger unit 41 loses power, it can control the first latch unit 43 to turn on, thereby driving the switch unit 42 to turn on, so as to output a working enable signal, thus completing the square wave trigger.

[0121] In this embodiment, for a falling-edge trigger signal, the clamping unit can accurately control the voltage at the controlled end of the first latching unit during its high-level stage to avoid mis-conduction. It only cooperates with the first trigger unit when the falling edge arrives to achieve the accurate conduction of the switching unit and the output of the working enable signal. For a square-wave trigger signal, the timing monitoring unit is combined to determine its timing validity. At the same time, the clamping effect of the clamping unit during the high-level stage is used to prevent the improper conduction of the first latching unit. When the falling edge appears, the conduction output of the working enable signal is realized. Overall, the accuracy and reliability of the device operation in these two trigger modes are greatly improved, effectively avoiding mis-triggering caused by factors such as abnormal signals or inappropriate timing, and ensuring that the subsequent power-consuming devices can work orderly according to the correct logic.

[0122] In an exemplary embodiment, as Figure 5 and Figure 7 shown, the clamping unit 45 includes a resistor R4 and a triode Q2. The first end of the resistor R4 is connected to the trigger signal output end of the signal generation module; the base of the triode Q2 is connected to the second end of the resistor R4, the collector of the triode Q2 is connected to the controlled end of the first latching unit 43, and the emitter of the triode Q2 is grounded.

[0123] Exemplarily, when the electrical signal input to the clamping unit 45 is in the high-level stage, the base of the triode Q2 in the clamping unit 45 is connected to a high voltage through the resistor R4, so that the triode Q2 conducts. Since the emitter of the triode Q2 is grounded, when the triode Q2 conducts, the potential at the controlled end of the first latching unit 43 is forced to be pulled down to the ground. When the electrical signal input to the clamping unit 45 is not in the high-level stage, the high voltage at the base of the triode Q2 in the clamping unit 45 disappears, resulting in the cut-off of the triode Q2, so that the potential at the controlled end of the first latching unit 43 is no longer clamped.

[0124] In this embodiment, through the simple circuit structure composed of the resistor R4 and the triode Q2, the potential at the controlled end of the first latching unit can be accurately controlled according to the level state of the input electrical signal. When the electrical signal is in the high-level stage, the triode Q2 can be effectively made to conduct and the potential of this controlled end is forced to be pulled down to the ground, avoiding possible mis-triggering and abnormal conduction situations during this stage and ensuring the accuracy of the circuit operation. When it is not in the high-level stage, the triode Q2 automatically cuts off, timely releasing the clamping of the potential, enabling the subsequent circuit to respond to signal changes according to the normal logic, overall improving the stability, reliability of the device operation in the relevant trigger modes and the accuracy of processing different level signals, and ensuring that the entire trigger control process is orderly and error-free.

[0125] In an exemplary embodiment, as Figure 9As shown, when the signal generation module 2 supports the output of a low-level enable trigger signal, the multi-mode trigger control module 4 further includes a second trigger unit 46. The power supply terminal of the second trigger unit 46 is connected to the power supply output terminal of the signal generation module 2, the single-signal trigger terminal of the second trigger unit 46 is connected to the trigger signal output terminal of the signal generation module 2, and the control terminal of the second trigger unit 46 is connected to the controlled terminal of the switch unit 42; the second trigger unit 46 is used to control the switch unit 42 to conduct when receiving a low-level enable trigger signal.

[0126] Exemplarily, under the power supply action of the power supply signal, when the second trigger unit 46 receives a low-level enable signal, the second trigger unit 46 will output a conduction signal to the controlled terminal of the switch unit 42, so that the switch unit 42 conducts under the action of the conduction signal, thereby outputting a working enable signal to the subsequent electrical equipment, so as to realize low-level enable trigger. Since the low-level enable trigger signal is output at this time, it has no effect on circuits such as the first trigger unit 41, the timing monitoring unit 44, and the clamping unit 45 that require high-level drive.

[0127] In this embodiment, when the signal generation module supports the output of a low-level enable trigger signal, the second trigger unit can specifically play a role in the case of low-level enable trigger. Through the reasonable connection of its power supply terminal and trigger signal output terminal, after receiving the corresponding low-level enable signal, it accurately outputs a conduction signal to control the switch unit to conduct, and then smoothly outputs a working enable signal to the subsequent electrical equipment, realizing the low-level enable trigger function. Moreover, it does not interfere with other circuits that rely on high-level drive, such as the first trigger unit, the timing monitoring unit, and the clamping unit, and each has a clear division of labor, further improving the flexibility, accuracy, and overall operation reliability of the entire multi-mode trigger control module when dealing with different level trigger signals, ensuring that the device can adapt to multiple trigger modes and work orderly.

[0128] In an exemplary embodiment, as Figure 9 shown, the second trigger unit 46 includes a resistor R1, a resistor R2, a triode Q1, a resistor R3, and a diode VD1. The first end of the resistor R1 is connected to the power supply output terminal of the signal generation module 2; the first end of the resistor R2 is connected to the second end of the resistor R1; the base of the triode Q1 is connected to the second end of the resistor R1, and the emitter of the triode Q1 is connected to the second end of the resistor R2; the first end of the resistor R3 is connected to the collector of the triode Q1, and the second end of the resistor R3 is connected to the controlled terminal of the switch unit 42; the anode of the diode VD1 is respectively connected to the second end of the resistor R2 and the emitter of the triode Q1, and the cathode of the diode VD1 is connected to the trigger signal output terminal of the signal generation module 2.

[0129] Exemplarily, taking the low-level enable trigger signal as the ground signal as an example, as Figure 9As shown in the figure, when the emitter of transistor Q1 is connected to the ground signal through diode VD1, transistor Q1 is turned on under the action of the power supply signal. Thus, the power supply signal is output to the controlled end of switch unit 42 through resistor R3, enabling switch unit 42 to conduct.

[0130] In this embodiment, in the circuit structure composed of resistor R1, resistor R2, transistor Q1, resistor R3, and diode VD1, when facing a low-level enable trigger signal (taking the ground signal as an example), through the collaborative cooperation among the components, transistor Q1 can be accurately turned on under the action of the power supply signal. Then, the power supply signal can be smoothly transmitted to the controlled end of the switch unit through resistor R3 to drive the switch unit to conduct, realizing the low-level enable trigger function. It not only has a relatively simple circuit design and low cost, but also can accurately and effectively respond to the low-level enable trigger signal, ensuring the reliable operation of the entire multi-mode trigger control module in the low-level trigger mode, enhancing the integrity and adaptability of the device in processing different types of trigger signals, and improving the overall practicality and stability of the system.

[0131] In an exemplary embodiment, as Figure 9 shown, switch unit 42 includes transistor Q9. The emitter of transistor Q9 is connected to the power supply output terminal of the signal generation module. The base of transistor Q9 is respectively connected to the control terminal of the second trigger unit 46 and the output terminal of the first latch unit 43. The collector of transistor Q9 is used to connect the subsequent electrical equipment.

[0132] In this embodiment, transistor Q9 is used as the switch unit. The emitter is connected to the power supply output terminal of the signal generation module to obtain power supply. The base is associated with the control terminal of the second trigger unit and the output terminal of the first latch unit to receive control signals in different trigger modes. The collector is connected to the subsequent electrical equipment to achieve power supply output. It can not only efficiently integrate the control logics corresponding to multiple trigger modes, accurately control the power supply on / off of the subsequent electrical equipment according to different trigger situations, but also, due to its simple structure, reduce the circuit complexity and hardware cost, enhancing the stability, reliability, and overall operation practicality of the entire device in different trigger mode applications.

[0133] In an exemplary embodiment, as Figure 9 shown, signal generation module 2 includes trigger switches X1, X2, and X3. The first terminal of trigger switch X1 is used to connect to the supply voltage, and the second terminal of trigger switch X1 is connected to the power supply terminal of multi-mode trigger control module 4. The first terminal of trigger switch X2 is connected to the second terminal of trigger switch X1, and the second terminal of trigger switch X2 is connected to the single-signal trigger terminal of multi-mode trigger control module 4. The first terminal of trigger switch X3 is connected to the second terminal of trigger switch X2, and the second terminal of trigger switch X3 is grounded.

[0134] Exemplarily, the output of the power supply signal can be controlled by controlling the on / off of the trigger switch X1, and by controlling the on / off sequence among the trigger switch X2, the trigger switch X3, and the trigger switch X1, the output of trigger signals such as high-level enable trigger signal, low-level enable signal, rising-edge trigger signal, falling-edge trigger signal, and square-wave signal can be achieved.

[0135] In this embodiment, through the settings of the trigger switch X1, the trigger switch X2, and the trigger switch X3, by controlling the on / off of the trigger switch X1, it is possible to conveniently control whether the power supply signal is output, providing basic power supply management for the operation of the entire system. On the other hand, by cleverly adjusting the on / off sequence among the trigger switch X2, the trigger switch X3, and the trigger switch X1, the output of various different types of trigger signals such as high-level enable trigger signal, low-level enable signal, rising-edge trigger signal, falling-edge trigger signal, and square-wave signal can be flexibly achieved, greatly enhancing the diversity and flexibility of signal generation, enabling the device to easily adapt to various different trigger requirement scenarios, improving the applicability, generality of the overall device in different application environments, and the convenience of implementing various trigger control functions, and overall optimizing the trigger signal generation and control process of the system.
