[0016] The technical solutions in the embodiments of the present application will be described clearly and completely below. Apparently, the described embodiments are only a part of the embodiments of the present application, rather than all of them. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0017] In this article, the term "including" is intended to cover non - exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such a process, method, article or device. Without more limitations, the elements defined by the statement "including..." do not exclude the existence of additional identical elements in the process, method, article or device including the said elements.

[0018] Embodiment 1

[0019] This embodiment discloses a short - circuit trigger module as shown in Figure 1 which includes a trigger unit and a low - level detection unit.

[0020] The trigger unit includes a connector CON5, a resistor R82 with a resistance value of 10KΩ, an optocoupler IS1 of model ELS357, diodes D4, D5, D6 of model 1N4148WS, a resistor R84 with a resistance value of 330R, and a resistor R221 with a resistance value of 0Ω.

[0021] Pin 1 of the connector CON5 is connected to the inherent circuit of the user end, pin 2 of the connector CON5 is connected to pin 1 of the resistor R221, and pin 2 of the resistor R221 is grounded. The inherent circuit is used to generate a control signal in an abnormal state, and the control signal is input through pin 1 of the connector CON5. It should be noted that the inherent circuit in this embodiment refers to the original circuit structure of the user, such as the controller or status monitor of mechanical equipment in the prior art, etc. These circuit structures will generate corresponding control signals in the corresponding states. In particular, the states here can be, for example: equipment power - off, equipment abnormality, etc. These are well - known to those of ordinary skill in the art, and are not elaborated in this text here.

[0022] Pin 1 of resistor R82 is connected to the +3.3V power supply. Pin 2 of resistor R82 is connected to the collector of the photodetector of optocoupler IS1. The emitter of the photodetector of optocoupler IS1 is grounded. The positive poles of the light-emitting diodes of optocoupler IS1 and diode D5 are both connected to the negative pole of diode D4. The positive pole of diode D4 is connected to the +5V power supply. The negative pole of the light-emitting diode of optocoupler IS1 is respectively connected to the positive pole of diode D5 and pin 1 of resistor R84. Pin 2 of resistor R84 is connected to the positive pole of diode D6. The negative pole of diode D6 is connected to pin 1 of connector CON5. And between pin 2 of resistor R82 and the collector of the photodetector of optocoupler IS1 is connected to the detection terminal of the low-level detection unit. The detection terminal of the low-level detection unit collects the low-level signal between pin 2 of resistor R82 and the collector of the photodetector of optocoupler IS1 when the control signal is input.

[0023] The working principle of the short-circuit trigger module in this embodiment is specifically as follows:

[0024] In the normal state, neither the right side nor the left side of the optocoupler is conducting. Resistors R82 and RB3 act as pull-up resistors, respectively making there be a 3.3V high voltage between resistor R82 and optocoupler IS1 and between resistor R83 and optocoupler IS2. In the abnormal state, the left side of the optocoupler receives the control signal and conducts, causing the right side of the optocoupler to conduct. At this time, resistors R82 and RB3 act as pull-down resistors, respectively making the voltages between resistor R82 and optocoupler IS1 and between resistor R83 and optocoupler IS2 change from high voltage to low voltage, and are detected by the low-level detection unit.

[0025] Embodiment 2

[0026] Different from Embodiment 1, in this embodiment, as Figure 2 shown, the negative pole of diode D4 is also connected with an extended trigger sub-unit. The extended trigger sub-unit is used to access other control signals generated by the inherent circuit and generate a low-level signal based on the other control signals. It should be noted that when using the short-circuit trigger module of the present invention to monitor the inherent circuit, the connector is connected to the output terminal of the corresponding circuit structure and receives the control signal generated by it.

[0027] In this embodiment, the extended trigger sub-unit includes connector CON4, resistor R83 with a resistance value of 10KΩ, optocoupler IS2 of model ELS357, diode D7 of model 1N4148WS, diode D8 of model 1N4148WS, resistor R85 with a resistance value of 330R, and resistor R220 with a resistance value of 0Ω.

[0028] Pin 1 of CON4 is connected to the inherent circuit. Pin 2 of connector CON4 is connected to pin 1 of resistor R220. Pin 2 of resistor R220 is grounded, and the control signal is input through pin 1 of connector CON4.

[0029] Pin 1 of resistor R83 is connected to the +3.3V power supply. Pin 2 of resistor R83 is connected to the collector of the photodetector of optocoupler IS2. The emitter of the photodetector of optocoupler IS2 is grounded. The positive poles of the light-emitting diodes of optocoupler IS2 and diode D7 are both connected to the negative pole of diode D4. The negative poles of the light-emitting diodes of optocoupler IS2 and the positive pole of diode D7 are both connected to Pin 1 of resistor R85. Pin 2 of resistor R85 is connected to the positive pole of diode D8. The negative pole of diode D8 is connected to Pin 1 of CON4. And between Pin 2 of resistor R83 and the collector of the photodetector of optocoupler IS2 is connected to the detection terminal of the low-level detection unit. The detection terminal of the low-level detection unit collects the low-level signal between Pin 2 of resistor R83 and the collector of the photodetector of optocoupler IS2 when a control signal is input.

[0030] Through the setting of the extended trigger subunit, without adding other monitoring circuits, it realizes that control signals generated by multiple routes of clients trigger the generation of low-level signals for backend processing, improves the adaptability to the inherent circuit, and has a simple structure and is cost-friendly.

[0031] The working principle of the short-circuit trigger module in this embodiment is specifically as follows:

[0032] When two or more control signals are accessed, each unit works independently, and the corresponding trigger unit or extended trigger subunit generates corresponding low-level signals for backend processing.

[0033] In summary, the short-circuit trigger module of this embodiment realizes the connection with the user's inherent circuit through the connection machine unit and receives the control signal sent by the inherent circuit; realizes the detection of the control signal through the trigger unit and generates an alarm signal; realizes the monitoring of the user's inherent circuit, has a simple structure and is cost-friendly, and can realize multiple routes of short-circuit trigger signals generated externally for backend processing.

[0034] Finally, it should be noted that the above are only the preferred embodiments of the present application and are not used to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
