Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0040] Reference Figure 1-3 This invention provides an emergency protection circuit device for high-voltage connectors. This device is an improvement on a previously applied patent, published (announced) with the number CN117673806A and titled "A High-Voltage Connector." The hardware components of the protection assembly in this application are essentially the same as those in the aforementioned patent.

[0041] The present invention provides an emergency protection circuit device suitable for a high-voltage connector, comprising: a protection component connected to the high-voltage connector; the protection component comprising: an upper connector for connecting to the high-voltage connector; a plurality of conductive plates arranged at the lower part of the upper connector; and the conductive plates are connected to an emergency protection circuit module arranged inside the upper connector through cables; the emergency protection circuit module comprises: an indication logic circuit, which is used to use a programmable controller as a carrier to form a plurality of warning voltage ranges formed based on a standard voltage threshold as a reference into a stepped warning value in a programmed form, and write the stepped warning value into the execution code of the main control logic to form an indication control logic; an execution logic circuit, which is configured to output an indication control instruction and an execution control instruction in response to the execution code of the main control logic, control the indication circuit using a transistor as a switching element through the indication control instruction, control the opening and closing of the indicator light through the indication circuit, and at the same time judge the corresponding warning level by triggering the switching element, and select and execute control of the isolation switch through the execution control instruction. This application incorporates an emergency protection circuit device within a high-voltage connector. The core of this device, a programmable controller, enables realistic initial parameter settings. For example, a reference voltage warning value can be set based on the high-voltage connector's reference voltage range, and multiple warning voltage ranges can be programmed to form a stepped warning value. Furthermore, this application incorporates indication logic, enabling different indications to be displayed for different warnings, with different on / off actions executed based on the warning level indicated.

[0042] In the above, the execution logic circuit includes: a sampling circuit coupled to the conductive sheet, the sampling circuit is used to obtain the instantaneous voltage flowing through the conductive sheet in real time; a conversion circuit for converting the instantaneous voltage, coupled to the sampling circuit, the conversion circuit is used to convert the instantaneous voltage into a monitoring value equivalent to the trigger value; a comparison circuit, coupled to the indication logic circuit and the conversion circuit, by comparing the monitoring value with the trigger value in the indication logic circuit, thereby enabling the corresponding event processing unit through the distribution network, and executing the indication control instruction and execution control instruction formed by the trigger value code through the event processing unit; an execution circuit, coupled to the comparison circuit, controls the indication circuit with a transistor as a switching element through the indication control instruction, controls the opening and closing of the indicator light through the indication circuit, and at the same time judges the corresponding warning level through the triggering of the switching element, and selects to execute the control of the isolation switch through the execution control instruction. Furthermore, the execution circuit includes: an execution circuit unit I, coupled to the comparison circuit, controlling the indication circuit with a transistor as a switching element based on the indication control instruction, and controlling the opening and closing of the indicator light through the indication circuit; an execution circuit unit II, coupled to the execution circuit unit I, judging the corresponding warning level by triggering the switching element in the execution circuit unit I; and an execution circuit unit III, coupled to the execution circuit unit II, selecting to execute control of the isolation switch through the execution control instruction based on the warning level.

[0043] In the above, the method for forming the indication control logic includes: configuring an event-driven processor in the main control logic with a programmable controller as the carrier; configuring a plurality of event processing units in the event-driven processor; configuring a response code corresponding to the response point for each event processing unit, and forming a trigger value code of the instruction set according to the response code, thereby forming the indication control logic.

[0044] In the above, the event-driven processor adopts EDA as the system architecture, in which the event processing unit serves as the core to promote the production, detection, processing and response of events. The first core of the event processing unit is to record the relevant event data through the event response code (trigger value code) and use it as the basis of the event data; the second core of the event processing unit is to use the event data as the basis to effectively associate different events; the third core of the event processing unit is to provide corresponding execution threads based on the trigger value code to realize the extraction and execution of instructions. Therefore, the EDA adopted by this application as the system architecture can handle complex events from multiple sources, and different events can affect each other in real time due to the existing association relationship. Secondly, the event-driven processor can set multiple event processing units according to the actual situation to meet the needs of different and multi-source complex events.

[0045] In the above description, the corresponding direction refers to writing a stepped warning value into the response code to form a trigger value code corresponding to the warning value. It should be noted that the stepped warning value is extracted from small to large to form multiple warning values, each of which constitutes a trigger range for event triggering. The trigger range represents the sole basis for whether an event trigger occurs. When the voltage value fluctuates and falls below the minimum warning value, an indicator light is used to warn, and a human judgement is made as to whether a power outage is required.

[0046] In order to enable the event-driven processor with EDA as the system architecture to effectively associate complex events from multiple sources, the present application configures a distribution network in the main control logic with a programmable controller as the carrier, and the distribution network is used to associate the step-by-step warning value with the event processing unit; and the distribution network is also used to record the trigger value code corresponding to each warning value, and to realize the extraction and execution of instructions by providing a corresponding execution thread for each trigger value code.

[0047] In the present application, the method by which the distribution network associates the step-by-step warning value with the event processing unit is as follows: the distribution network extracts the step-by-step warning values ​​respectively from small to large; a trigger value code corresponds to each of the warning values, and the trigger value code forms a specified trigger range based on the warning value; when the warning value exceeds the trigger range, the condition for responding to the event is met, and at this time the event processing unit executes the trigger value code to form a corresponding pointing instruction; wherein, each of the trigger value codes is formed to correspond to a pointing instruction, and a plurality of the pointing instructions constitute the instruction set.

[0048] In the above, the trigger value code has an execution code segment formed by programming and a parameter setting segment associated with the execution code segment, and the parameter setting segment is associated with the execution code segment through a pointing code.

[0049] In the above, the pointing instructions include indication control instructions and execution control instructions.

[0050] In the above, the isolating switch is coupled to the execution circuit unit III in the execution circuit, and the isolating switch is arranged between the high-voltage cable and the conductive sheet, and is used as an on-off switch between the high-voltage cable and the conductive sheet.

[0051] The main principle of this application is as follows: This application provides an emergency protection circuit device within a high-voltage connector. The core component of this emergency protection circuit device is a programmable controller, which can be used to set initial parameters. For example, the reference voltage warning value is set according to the reference voltage range of the high-voltage connector, and multiple warning voltage ranges are programmed to form a stepped warning value. At the same time, this application introduces indication logic, which can display different indications for different warnings and perform different execution on and off according to the warning level of the indication display. Specifically, the sampling circuit is used to obtain the instantaneous voltage flowing through the conductive plate in real time; the conversion circuit is used to convert the instantaneous voltage into a monitoring value equivalent to the trigger value; by comparing the monitoring value with the trigger value in the indication logic circuit, the corresponding event processing unit is activated through the distribution network, and the event processing unit executes the indication control instruction and execution control instruction formed by the trigger value code; based on the indication control instruction, the indication circuit, which uses a transistor as a switching element, is controlled to turn on and off the indicator light through the indication circuit; the corresponding warning level is determined by triggering the switching element in the execution circuit unit I; and based on the warning level, the execution control instruction is used to select and execute the control of the isolation switch.
