Description

Technical Field

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

[0002] With the advancement of intelligent manufacturing, the safe operation of domestic construction machinery has received attention, and the requirements for safety control, error prevention and miniaturization have become increasingly higher. The improvement of electronic components on 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 the event of a fault or misoperation. The traditional trigger (reset) circuit starts the equipment by pressing a trigger button. When the safety input loop is closed, the trigger button function is short-circuited or short-circuited.

[0004] However, the traditional logic electrical component triggering method has many limitations. The multi-port control method increases the number of control ports, which is not conducive to miniaturization design; the software control logic relies on the microcontroller trigger, which increases the human-machine operation requirements and makes it difficult to control the cost.

[0083] When used herein, the singular forms "a", "an", and "said / the" may also include plural forms, unless the context clearly indicates otherwise. It should also be understood that the terms "include / comprise" or "have" and the like specify the presence of stated features, wholes, steps, operations, components, parts, or combinations thereof, but do not exclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts, or combinations thereof. At the same time, the term "and / or" used in this specification includes any and all combinations of the relevant listed items.

[0084] In an exemplary embodiment, as shown in FIG1 , the present application provides a device for realizing different trigger modes with a single port, and the device includes a signal generating module 2 and a multi-mode trigger control module 4. The power supply output terminal of the signal generating module 2 is used to access the power supply voltage, and the signal generating module 2 is used to support the output of the 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 generating module 2, and the single signal trigger terminal of the multi-mode trigger control module 4 is connected to the trigger signal output terminal of the signal generating module 2. The multi-mode trigger control module 4 is used to receive the power supply signal and the trigger signal, and output the work enable signal to the back-end power-consuming device when the trigger signal meets the preset trigger condition corresponding to the trigger signal.

[0085] Among them, the type of trigger signal may refer to an electrical signal of different forms or modes 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 may 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 voltage level (high level or low level); pulse trigger: triggered by a voltage or current pulse in a short time. The preset trigger condition may refer to a pre-set rule or standard in the multi-mode trigger control module 4, which is used to determine whether the received trigger signal meets a certain type of definition, thereby determining whether to output a work enable signal; the preset trigger condition may also refer to the conduction condition of the hardware circuit in the multi-mode trigger control module 4, which is used to verify whether the received trigger signal meets the conduction condition of the hardware circuit in the multi-mode trigger control module 4, thereby determining whether to output a work 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 it as a valid trigger and execute the corresponding action. Taking edge triggering as an example, the preset trigger condition may include the provision of the time point at which the rising edge or falling edge appears. In some applications, it may 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, and the time difference between the two should be kept within a certain range, a valid edge trigger can be constituted.

[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, and these trigger signals differ in waveform, frequency, duration, voltage level, etc., such as edge trigger, level trigger, pulse trigger, etc. The power supply end of the multi-mode trigger control module 4 is connected to the power supply output end of the signal generation module 2, and its single signal trigger end receives the trigger signal. The multi-mode trigger control module 4 has corresponding preset trigger conditions for different trigger signals according to pre-set rules, or has corresponding circuit conduction conditions for different trigger signals according to pre-designed circuits. For example, edge triggering requires judging the time point when the rising edge or falling edge occurs, including the relative timing relationship and time difference range between the power supply signal and the edge trigger signal; level triggering requires the signal to maintain a specific level for at least a minimum period of time, etc. When the received trigger signal meets the preset trigger condition of its corresponding type, the multi-mode trigger control module 4 will output a work enable signal to the back-end 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 multiple trigger modes are 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. Only one port can meet multiple trigger requirements, which effectively saves hardware resources. Moreover, the circuit structure is relatively simple, and there is no need for complex and expensive multi-port control circuits and related supporting facilities, which reduces the hardware cost investment. At the same time, the multi-mode trigger control module can automatically identify and process trigger signals according to preset rules or circuits, which reduces the requirements for the technical level of operators, greatly improves the practicality and economy of the system, and provides an efficient, convenient and economical solution for the trigger control of related equipment or systems.

[0088] In an exemplary embodiment, the signal generating module 2 is used to support outputting at least two of the following trigger signals: 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.

[0089] The trigger signal 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, which greatly enriches the selection diversity of trigger signals, and can meet the different requirements of different back-end electrical equipment or complex systems for trigger mechanisms under various working conditions and functional requirements, so that the applicability of the entire device is greatly expanded. For example, in some level-sensitive circuits, high-level or low-level enable trigger signals can be used for precise control, while in timing logic-related circuits, rising edge or falling edge trigger signals can effectively realize state switching and synchronization, and square wave trigger signals can be used to drive periodic actions, thereby realizing effective adaptation to a variety of devices and systems in a flexible and changeable triggering manner, and improving the overall performance and compatibility of the system.

[0091] In an exemplary embodiment, as shown in FIG2 , in the case where the signal generation module 2 supports the output of a high-level enable trigger signal, the multi-mode trigger control module 4 includes a first trigger unit 41 and a switch unit 42. The single signal trigger end of the first trigger unit 41 is connected to the trigger signal output end of the signal generation module 2; the input end of the switch unit 42 is connected to the power supply output end of the signal generation module 2, and the controlled end of the switch unit 42 is connected to the control end 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] For example, since there is no requirement for the output timing of the high-level trigger signal during actual application, 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 turn on, so that the power supply voltage output from the power supply output end of the signal generating module 2 is used as a working enable signal, and is output to the back-end 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 the high-level enable trigger signal is realized. 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, thereby simplifying the trigger logic and improving the response speed and reliability of the system. Specifically, once a high-level trigger signal is received, the first trigger unit immediately controls the switch unit to turn on, so that the power supply voltage can be directly transmitted to the back-end power-consuming device as a work enable signal. It not only reduces the complexity of signal processing, but also ensures a fast and stable power supply, enhances the flexibility and practicality of the system, and is particularly suitable for application scenarios that require instant response. In addition, since it does not rely on complex timing control, the solution also reduces design and maintenance costs and improves the ease of use and stability of the overall system.

[0094] In an exemplary embodiment, as shown in FIG2 , 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 generating 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, the signal charges the capacitor C1 through the diode VD3, and at the same time outputs a control signal to the controlled end of the switch unit 42 through the resistor R6, so that the switch unit 42 is turned on, and then the power supply signal output by the signal generation module 2 is used as a work enable signal, and is output to the back-end power-consuming device through the switch unit 42. In some embodiments, a diode VD2 is further provided between the anode of the transistor VD3 and the trigger signal output end of the signal generation module 2 to prevent reverse transmission of the signal.

[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, as shown in FIG2 , 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, as shown in FIG2 , the first latch unit 43 includes a capacitor C3, a diode VD4, a transistor Q3, a transistor Q4, a resistor R7, and a resistor R8. The first end of the capacitor C3 is connected to the control end of the first trigger 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 transistor Q3 is connected to the cathode of the diode VD4, and the emitter of the transistor Q3 is grounded; the collector of the transistor Q4 is connected to the base of the transistor Q3, and the base of the transistor Q4 is connected to the collector of the transistor Q3; the first end of the resistor R7 is connected to the emitter of the transistor Q4, and the second end of the resistor R7 is connected to the controlled end of the switch unit 42; the first end of the resistor R8 is connected to the base of the transistor Q4, and the second end of the resistor R8 is connected to the second end of the resistor R7.

[0101] Exemplarily, the electric signal output by the first trigger unit 41 charges the capacitor C3, and at the same time is output to the base of the transistor Q3 through the diode VD4 to turn on the transistor Q3. When the transistor Q3 is turned on, the potential of the controlled end of the switch unit 42 and the potential of the base of the transistor Q4 are pulled down. Since the input end of the switch unit 42 is connected to the power supply output end of the signal generation module 2, the input end of the switch unit 42 is turned on under the action of the power supply voltage, so that the power supply voltage output by the signal generation module 2 is converted into a work enable signal and output to the back-end electrical equipment. At the same time, when the switch unit 42 is turned on, the potential of the emitter of the transistor Q4 is greater than the potential of its base, and the transistor Q4 is turned on, causing the potential of the base of the transistor Q3 to be pulled up all the time, so that the potential of the base of the transistor Q3 is always greater than the potential of its emitter when the switch unit 42 is turned on, so that the transistor Q3 is always turned on, and the switch unit 42 remains in the on state after being turned on for the first time.

[0102] In this embodiment, through the first latch unit composed of capacitor C3, diode VD4, transistor Q3, transistor Q4, resistor R7 and resistor R8, capacitor C3 and diode VD4 can cooperate to process the electrical signal output by the first trigger unit and transmit it to the base of transistor Q3 to control its conduction. On this basis, by utilizing the connection between transistors Q3 and Q4 and the functions of resistors R7 and R8, it is achieved that after the switch unit is turned on for the first time, transistor Q3 can be kept in the on state, so that the switch unit can be continuously 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 output to the back-end electrical equipment, avoiding the situation where the switch unit is accidentally disconnected due to external interference, signal fluctuations and other factors, ensuring the continuity and stability of the operation of the back-end electrical equipment. At the same time, the circuit structure is relatively simple, and while realizing the latching function, it takes into account the needs of cost control and efficient operation.

[0103] In an exemplary embodiment, as shown in FIG3 , 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 used to prohibit the output of the shutdown 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 and the rising edge trigger signal of the signal generating module 2 are output simultaneously, the timing monitoring unit 44 will receive the power supply signal and the rising edge trigger signal simultaneously. At this time, the timing monitoring unit 44 will determine that the timing of the rising edge trigger signal is wrong, that is, it will determine that the rising edge trigger signal is an invalid rising edge trigger signal, and thus 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 then the switch unit 42 remains cut off, and no work enable signal is output to the back-end electrical equipment at this time. 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 wrong, and will also determine that the rising edge trigger signal is an invalid rising edge trigger signal, 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. 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 recognizes 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 shutdown signal to the first latch unit 43, so that the first latch unit 43 remains turned on under the drive of the first trigger unit 41, so that under the action of the rising edge trigger signal, the power supply signal can be output as a work enable signal to the back-end electrical equipment through the switch unit 42.

[0105] In this embodiment, by adding a timing monitoring unit, the output timings of the power supply signal and the rising edge trigger signal are accurately monitored and judged, thereby effectively regulating the timing relationship of the signals, ensuring that only when the output timing of the power supply signal is earlier than the output timing 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 be turned on under the drive of the first trigger unit, so that the work enable signal can be normally output to the back-end electrical equipment. In the event of a timing error, such as when the power supply signal and the rising edge trigger signal are output at the same time or the rising edge trigger signal is output earlier than the power supply signal, the shutdown signal can be output in time to cut off the first latch unit, thereby avoiding false triggering and abnormal work enable signal output due to incorrect timing, greatly improving the accuracy, reliability and stability of the entire device operating in the rising edge trigger mode, and ensuring that the back-end electrical equipment can work in an orderly manner according to the correct trigger logic.

[0106] In an exemplary embodiment, as shown in FIG3 , the timing monitoring unit 44 includes a charging unit 442 and a second latch unit 444. The power supply end of the charging unit 442 is connected to the power supply output end of the signal generating module 2, and the input end of the charging unit 442 is connected to the trigger signal output end of the signal generating module 2; the power supply end of the second latch unit 444 is connected to the power supply output end of the signal generating module 2, the input end of the second latch unit 444 is connected to the output end of the charging unit 442, and the output end of the second latch unit 444 is connected to the controlled end of the first latch unit 43.

[0107] The charging unit 442 is used to determine 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, and the charging unit 442 can calculate the cumulative charging time based on the time node of receiving the power supply signal as the timing starting point. If the charging unit 442 receives a rising edge trigger signal before the cumulative charging time reaches the preset charging time, the charging unit 442 will control the second latch unit 444 to be turned on, so that the second latch unit 444 outputs a shutdown signal to the first latch unit 43 under the power supply of the power supply signal, thereby controlling the switch unit 42 to remain turned off. If the charging unit 442 receives a rising edge trigger signal after the cumulative charging time reaches the preset charging time, the charging unit 442 will control the second latch unit 444 to be turned off, so that the second latch unit 444 cannot output a shutdown signal to the first latch unit 43, so that the first trigger unit 41 can output a conduction signal when receiving the rising edge trigger signal to turn on the first latch unit 43, thereby controlling the conduction of the switch unit 42.

[0109] Specifically, when the output time of the power supply signal is the same as the output time of the rising edge trigger signal, the power supply signal and the rising edge trigger signal act on the charging unit 442 at the same time; and when the output time of the power supply signal is later than the output time of the rising edge trigger signal, the power supply signal will act 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 at the same time as the power supply signal, that is, before the accumulated charging time reaches the preset charging time, the charging unit 442 will receive the rising edge trigger signal, so that the charging unit 442 outputs a conduction signal to the second latch unit 444 to drive the second latch unit 444 to turn on, so that the second latch unit 444 outputs a shutdown signal to the first latch unit 43, so that the first latch unit 43 remains turned off, and then the switch unit 42 remains turned off. When the output time of the power supply signal is earlier than the output time of the rising edge trigger signal, the power supply signal acts on the charging unit 442 before the rising edge trigger signal, that is, the charging unit 442 receives the rising edge trigger signal only after the cumulative charging time reaches the preset charging time. At this time, the charging unit 442 will not output the conduction signal to the second latch unit 444, so that the second latch unit 444 is cut off and cannot output the 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 turn on the first latch unit 43, thereby controlling the conduction of the switch 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 realize that the switch unit 42 is turned on only when the rising edge trigger timing is correct, and the work enable signal is output to the back-end power-consuming equipment to complete the rising edge trigger.

[0110] In this embodiment, accurate identification of the timing of the rising edge trigger signal is achieved through the cooperation between the charging unit and the second latch unit in the timing monitoring unit. The charging unit charges and times based on the power supply signal, and controls the on or off state of the second latch unit according to the relationship between the received rising edge trigger signal and the preset charging duration, thereby controlling the state of the first latch unit and the switch unit. Based on this, it can ensure that the switch unit is turned on only when the rising edge trigger timing is correct, and output the work enable signal to the back-end power-consuming device, effectively avoiding erroneous operations caused by timing errors, and improving the stability and reliability of the system.

[0111] In an exemplary embodiment, as shown in FIG3 , the charging unit 442 includes a capacitor C2, a resistor R9, a resistor R10, a transistor Q5, and a transistor Q6. The first end of the capacitor C2 is connected to the power supply output end of the signal generating 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 transistor Q5 is connected to the second end of the resistor R10, and the emitter of the transistor Q5 is grounded; the base of the transistor Q6 is connected to the collector of the transistor Q5, the emitter of the transistor Q6 is connected to the trigger signal output end of the signal generating module 2, and the collector of the transistor Q6 is connected to the input end of the second latch unit 444.

[0112] Exemplarily, as shown in FIG4 , X1 represents a power supply signal, X2 represents a rising edge trigger signal, and Y1 represents a work 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 transistor Q5 is turned on during the charging process of the capacitor C2, the base potential of the transistor Q6 is pulled down, and the emitter of the transistor Q6 is connected to the rising edge trigger signal X2, so the transistor Q6 is turned on and outputs a turn-on signal to the second latch unit 444 to drive the second latch unit 444 to output a turn-off signal to the first latch unit 43, so that the first latch unit 43 is turned off, so that the switch unit 42 is turned off, and no work 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 first input power supply signal X1, that is, before the emitter of the transistor Q6 receives the rising edge trigger signal X2, the capacitor C2 is fully charged, and the base of the transistor Q5 will maintain a low level after the capacitor C2 is fully charged, that is, the transistor Q5 is in the cut-off state. At this time, since the transistor Q5 is in the cut-off state, even if the emitter of the transistor Q6 receives the rising edge trigger signal X2, the transistor Q6 cannot be turned on, that is, it cannot output the turn-on signal to the second latch unit 444, and the second latch unit 444 cannot output the turn-off signal to the first latch unit 43, so that the turn-on signal output by the first trigger unit 41 when receiving the rising edge trigger signal X2 can turn on the first latch unit 43, thereby controlling the conduction of the switch unit 42 to output the work enable signal Y1. In this embodiment, the charging time for fully charging the capacitor C2 can be changed by changing the capacitance value of the capacitor C2, thereby changing the preset charging time and adapting to 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, transistor Q5 and transistor Q6, the state of each subsequent unit can be accurately controlled according to the output sequence of the power supply signal and the rising edge trigger signal, effectively avoiding false triggering caused by erroneous timing conditions 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 work enable signal. At the same time, by changing the capacitance value of capacitor C2 to flexibly adjust the full charge time, and then change the characteristics of the preset charging time, it can be well adapted to various application scenarios with different timing recognition accuracy requirements, enhance the adaptability and flexibility of the entire device to cope with different working conditions in the rising edge trigger mode, and improve the reliability, accuracy and overall practicality and compatibility of the system operation.

[0114] In an exemplary embodiment, as shown in FIG3 , the second latch unit 444 includes a resistor R11, a transistor Q7, a transistor Q8, a resistor R12, and a resistor R13. The first end of the resistor R11 is connected to the output end of the charging unit 442; the collector of the transistor Q7 is connected to the second end of the resistor R11; the base of the transistor Q8 is connected to the collector of the transistor Q7, the collector of the transistor Q8 is respectively connected to the base of the transistor Q7 and the controlled end of the first latch unit 43, and the emitter of the transistor Q8 is grounded; the first end of the resistor R12 is connected to the emitter of the transistor Q7, and the second end of the resistor R12 is connected to the power supply output end of the signal generation module 2; the first end of the resistor R13 is connected to the power supply output end of the signal generation module 2, and the second end of the resistor R13 is connected to the collector of the transistor Q8.

[0115] Exemplarily, when the on signal output by the charging unit 442 is input to the base of the transistor Q8 via the resistor R11, the transistor Q8 is turned on, and the base potential of the transistor Q7 is pulled down. Since the emitter of the transistor Q7 is connected to the power supply signal via the resistor R12, the transistor Q7 is turned on under the action of the power supply signal, and the transistor Q8 is self-locked through the transistor Q7. Since the controlled end of the first latch unit 43 is connected to the collector of the transistor Q8, when the transistor Q8 is turned on, the potential of the controlled end of the first latch unit 43 is also forced to be pulled down, that is, the off signal is output to the controlled end of the first latch unit 43. In the above case, even if the first trigger unit 41 outputs the on 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 be turned on and remains in the off state, so that the switch unit 42 cannot be turned on, that is, the work enable signal cannot be output to the back-end electrical equipment. When the charging unit 442 cannot output a conduction signal to the second latch unit 444, the transistors Q7 and Q8 cannot be turned on naturally, and the potential of the controlled end of the first latch unit 43 will not be forced to be pulled down, that is, the shutdown signal cannot be output to the controlled end of the first latch unit 43.

[0116] In this embodiment, through the second latch unit composed of resistor R11, transistor Q7, transistor Q8, resistor R12 and resistor R13, when the charging unit outputs a conduction signal, self-locking is achieved through the interaction between the internal transistors, and the shutdown signal is reliably output to the first latch unit, effectively preventing false triggering due to non-compliance with the trigger timing and the like, ensuring that the switch unit will not be erroneously turned on and avoiding the work enable signal from being erroneously output to the back-end electrical equipment, thereby ensuring 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 latch unit. This orderly and precise control mechanism improves the overall reliability and operation accuracy of the device when dealing with different signal conditions, so that the system can perform trigger operations according to the correct logic.

[0117] In an exemplary embodiment, when the signal generating 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 trigger signal generating circuit, and the output end of the clamping unit 45 is connected to the controlled end of the first latch unit 43, so as to provide a clamping voltage to the first latch unit 43.

[0118] Exemplarily, when the signal generating module 2 supports the output of the falling edge trigger signal, the circuit structure diagram of the multi-mode trigger control module 4 is shown in FIG5 . The specific implementation process takes the timing diagram shown in FIG6 as an example, wherein X1 is the power supply signal, X2 is the falling edge trigger signal, and Y1 is the work enable signal. When the trigger signal generating 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. In 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, and the clamping unit 45 controls the voltage of the controlled end of the first latch unit 43 to the clamping voltage, so that the first latch unit 43 cannot be turned on, so that the switch unit 42 is turned off, and no work enable signal Y1 is output at this time. At the falling edge of the falling edge trigger signal X2, the clamping unit 45 and the first trigger unit 41 lose power at the same time, and the clamping unit 45 can no longer provide the clamping voltage to the first latch unit 43. Since the capacitor C1 in the first trigger unit 41 is charged during the high level stage of the falling edge 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 to output a work enable signal.

[0119] When the signal generation module 2 supports the output of the square wave trigger signal, the circuit structure diagram of the multi-mode trigger control module 4 is shown in FIG7. The specific implementation process takes the timing diagram shown in FIG8 as an example, wherein X1 is the power supply signal, X2 is the square wave trigger signal, and Y1 is the work 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 wrong, that is, it is determined that the square wave trigger signal X2 is an invalid square wave trigger signal X2, thereby outputting 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 then the switch unit 42 remains cut off. At this time, no work enable signal is output to the back-end 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 wrong, 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. 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 phase 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 phase of the square wave trigger signal, so that the first latch unit 43 cannot be turned on during the high level phase of the square wave trigger signal. At the falling edge of the square wave trigger signal X2, the clamp unit 45 and the first trigger unit 41 lose power at the same time, and the clamp unit 45 can no longer provide the clamp voltage to the first latch unit 43. Since the capacitor C1 in the first trigger unit 41 is charged during the high level phase 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 work enable signal, thereby completing the square wave trigger.

[0121] In this embodiment, for the falling edge trigger signal, the clamping unit can accurately control the voltage at the controlled end of the first latch unit in its high level stage to avoid false conduction, and only cooperate with the first trigger unit to realize the accurate conduction of the switch unit and the output of the work enable signal when the falling edge arrives; for the square wave trigger signal, the timing monitoring unit is combined to determine its timing validity, and at the same time, the clamping effect of the clamping unit in the high level stage is used to prevent the first latch unit from being improperly turned on, and the conduction and output of the work enable signal are realized when the falling edge appears. Overall, the accuracy and reliability of the device in these two trigger modes are greatly improved, and false triggering caused by factors such as abnormal signals or improper timing is effectively avoided, ensuring that the back-end electrical equipment can work in an orderly manner according to the correct logic.

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

[0123] Exemplarily, when the electrical signal input to the clamping unit 45 is in a high level stage, the base of the transistor Q2 in the clamping unit 45 is connected to a high voltage via the resistor R4, so that the transistor Q2 is turned on. Since the emitter of the transistor Q2 is grounded, when the transistor Q2 is turned on, the potential of the controlled end of the first latch unit 43 is forced to be pulled down to the ground. When the electrical signal input to the clamping unit 45 is in a non-high level stage, the high voltage of the base of the transistor Q2 in the clamping unit 45 disappears, causing the transistor Q2 to be turned off, so that the potential of the controlled end of the first latch unit 43 is no longer clamped.

[0124] In this embodiment, through a circuit structure composed of a simple resistor R4 and a transistor Q2, the potential of the controlled end of the first latch unit can be accurately controlled according to the input electrical signal level state. When the electrical signal is in a high level stage, the transistor Q2 can be effectively turned on and the potential of the controlled end can be forced to be pulled down to the ground, thereby avoiding false triggering and abnormal conduction that may occur in this stage, and ensuring the accuracy of circuit operation; when it is in a non-high level stage, the transistor Q2 is automatically cut off, and the potential clamp is released in time, so that the subsequent circuit can respond to signal changes according to normal logic, which improves the stability and reliability of the device in the relevant trigger mode and the accuracy of processing signals of different levels, ensuring that the entire trigger control process is orderly and error-free.

[0125] In an exemplary embodiment, as shown in FIG9 , in the case where 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 end of the second trigger unit 46 is connected to the power supply output end of the signal generation module 2, the single signal trigger end of the second trigger unit 46 is connected to the trigger signal output end of the signal generation module 2, and the control end of the second trigger unit 46 is connected to the controlled end 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 of the power supply signal, when the second trigger unit 46 receives the low-level enable signal, the second trigger unit 46 will output a conduction signal to the controlled end of the switch unit 42, so that the switch unit 42 is turned on under the action of the conduction signal, thereby outputting a work enable signal to the back-end power-consuming device, thereby realizing a low-level enable trigger. Since the output at this time is a low-level enable trigger signal, it does not work for the first trigger unit 41, the timing monitoring unit 44, the clamping unit 45 and other circuits 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 play a role specifically for the low-level enable trigger. Through the reasonable connection between its power supply end and the trigger signal output end, after receiving the corresponding low-level enable signal, it accurately outputs the conduction signal to control the switch unit to conduct, and then smoothly outputs the work enable signal to the back-end power-consuming equipment to achieve 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, which further improves the flexibility, accuracy and overall operation reliability of the entire multi-mode trigger control module when dealing with trigger signals of different levels, and ensures that the device can adapt to multiple trigger modes and work in an orderly manner.

[0128] In an exemplary embodiment, as shown in FIG9 , the second trigger unit 46 includes a resistor R1, a resistor R2, a transistor Q1, a resistor R3 and a diode VD1. The first end of the resistor R1 is connected to the power supply output end 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 transistor Q1 is connected to the second end of the resistor R1, and the emitter of the transistor 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 transistor Q1, and the second end of the resistor R3 is connected to the controlled end of the switch unit 42; the anode of the diode VD1 is connected to the second end of the resistor R2 and the emitter of the transistor Q1, respectively, and the cathode of the diode VD1 is connected to the trigger signal output end of the signal generation module 2.

[0129] Exemplarily, taking the low-level enable trigger signal as the ground signal as an example, as shown in FIG9 , when the emitter of transistor Q1 is connected to the ground signal via diode VD1, transistor Q1 is turned on under the action of the power supply signal, so that the power supply signal is output through resistor R3 to the controlled end of the switch unit 42, so that the switch unit 42 is turned on.

[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), the coordination between the various components can be used to make the transistor Q1 accurately turned on under the action of the power supply signal, and then the power supply signal is smoothly transmitted to the controlled end of the switch unit through the resistor R3 to drive the switch unit to turn on, thereby realizing the low-level enable trigger function. Not only is the circuit design relatively simple and low-cost, but it can also 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 to the processing of different types of trigger signals, and improving the overall practicality and stability of the system.

[0131] In an exemplary embodiment, as shown in Fig. 9, the switch unit 42 includes a transistor Q9. The emitter of the transistor Q9 is connected to the power supply output terminal of the trigger signal generating circuit, the base of the 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, and the collector of the transistor Q9 is used to connect to the back-end electrical equipment.

[0132] In this embodiment, transistor Q9 is used as a switching unit, with the emitter connected to the power supply output end of the trigger signal generating circuit to obtain power supply, the base is associated with the second trigger unit control end and the first latch unit output end to receive control signals under different trigger modes, and the collector is connected to the back-end electrical equipment to realize power supply output. It can not only efficiently integrate the control logic corresponding to a variety of trigger modes and accurately control the power supply to the back-end electrical equipment according to different trigger conditions, but also because of its simple structure, it reduces the complexity of the circuit and the hardware cost, and enhances the stability, reliability and overall practicality of the entire device in different trigger mode applications.

[0133] In an exemplary embodiment, as shown in Fig. 9, the signal generating module 2 includes a trigger switch X1, a trigger switch X2 and a trigger switch X3. The first end of the trigger switch X1 is used to access the power supply voltage, and the second end of the trigger switch X1 is connected to the power supply end of the multi-mode trigger control module 4; the first end of the trigger switch X2 is connected to the second end of the trigger switch X1, and the second end of the trigger switch X2 is connected to the single signal trigger end of the multi-mode trigger control module 4; the first end of the trigger switch X3 is connected to the second end of the trigger switch X2, and the second end of the trigger switch X3 is grounded.

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

[0135] In this embodiment, by setting the trigger switch X1, the trigger switch X2 and the trigger switch X3, and by controlling the on and off of the trigger switch X1, it is possible to conveniently control whether the power supply signal is output or not, and provide basic power supply management for the operation of the entire system. On the other hand, by cleverly adjusting the on and off sequence between the trigger switch X2, the trigger switch X3 and the trigger switch X1, it is possible to flexibly realize the output of various types of trigger signals such as high-level enable trigger signals, low-level enable signals, rising edge trigger signals, falling edge trigger signals and square wave signals, which greatly enhances the diversity and flexibility of signal generation, allowing the device to easily adapt to a variety of different trigger demand scenarios, improving the applicability and versatility of the overall device in different application environments, and the convenience of realizing various trigger control functions, and overall optimizing the system's trigger signal generation and control process.
