Description

Technical Field

[0001] The present invention relates to the technical field of power distribution room operation and maintenance, and in particular to an audio-visual warning device for power distribution room switch operation power outage. Background Art

[0002] The switches in the distribution room are key control and protection equipment in the power system, mainly including isolating switches, load switches and circuit breakers. Isolating switches are mainly used to separate circuits to improve the safety of maintenance and inspection work; load switches are installed at the end of the distribution system to control the switching and protection of loads; circuit breakers can cut off the current when the circuit is short-circuited or overloaded to protect the safety of electrical equipment. Switchgear can not only effectively control the opening and closing of circuits, but also ensure the safe operation of electrical equipment and improve the efficiency and convenience of power use. During operation, it is necessary to strictly abide by the operating procedures to improve power safety.

[0003] In actual use, the technology of the sound and light warning system for power outage during switch operation in the distribution room has realized real-time monitoring and early warning of the switch status of the distribution room by integrating advanced sensors, controllers and sound and light alarm devices. When the switch in the distribution room is operated, the system will start immediately and send out obvious warning signals through the sound and light alarm, including flashing LED lights and preset voice prompts, such as "There is a ground fault in the equipment, please do not approach; on-site personnel should keep their feet together and evacuate 4 meters away from the equipment", etc., to inform on-site personnel of the current operation status and potential safety risks in an intuitive and clear way. This system not only improves the safety of distribution room operation, but also reduces the risk of accidents caused by misoperation or ignoring safety warnings, providing a strong guarantee for the stable operation of the power system. At the same time, the system usually has the advantages of simple wiring, reliable operation, instantaneous alarm, low cost and easy installation, making it more and more widely used in power systems.

[0004] The operation of power system switch power outage is an extremely meticulous and cautious job. In the past, there have been many cases of personal injury and death accidents caused by going to the wrong interval. Through the above invention, it plays an auxiliary warning role. The local switch body is equipped with flashing lights, making it easier for people to confirm the switch that needs to be operated, and synchronize the five-protection system. The existing switch cabinet only has five-protection locks. The specifications of the switch cabinets are the same. It is necessary to confirm the switch cabinet identification plate. There is no identification behind the switch cabinet, which makes it easy to go to the wrong interval and cause unsafe incidents. Based on this, the present invention designs an audio-visual warning device for power distribution room switch operation power outage, which can quickly determine and confirm the switch cabinet that needs to be operated to solve the above problems.

When a switch operation occurs, the sensor collects the switch operation data and transmits the switch operation data to the controller module. The switch operation data includes the switch status information and operation time.

[0058] Before the data is transmitted to the controller module, the sensor module pre-processes the data, and the pre-processed data will be transmitted to the controller module;

[0059] If the controller module determines that there is danger or a switch cabinet that needs to be operated based on the data transmitted by the sensor module, the sensor module cooperates with the controller module to start the sound and light alarm device and the light flashing device. The sensor module also synchronizes information with the microcomputer five-protection locking system.

[0060] Specifically, the present invention provides an audio and visual warning device for stopping power supply when a switch in a distribution room is operated, and the controller module is also used for:

[0061] Receive the data transmitted from the sensor module. After receiving the data, the controller module analyzes the data;

[0062] The controller module matches and compares the parsed data with the preset safety standards or operation rules to determine whether the current switch status meets expectations and whether the operation time is within the allowable range;

[0063] Based on the results of data matching and comparison, the controller module performs a risk assessment. If the assessment results show that there is a danger or a switch cabinet that needs to be operated, the controller module matches the corresponding decision based on the preset knowledge base, that is, starts the sound and light alarm device and the light flashing device.

[0064] Specifically, the present invention provides an audio and visual warning device for stopping power supply when a switch in a distribution room is operated, and the controller module is also used for:

[0065] The controller module receives the switch status data of the power distribution room collected by the sensor module, and the switch status data of the power distribution room includes the current status of the switch, the operation timestamp and;

[0066] The controller module substitutes the switch status data of the distribution room into the preset early warning model for processing. The early warning model is used to analyze the data and determine whether there is a potential danger or risk of misoperation;

[0067] In the early warning model, the controller module processes the data and generates early warning analysis results, which include whether there is danger and the switch cabinet that needs to be operated. If the early warning analysis results show danger, the controller module will start the sound and light alarm device and the light flashing device.

[0068] According to the early warning analysis results, the controller module sends early warning instructions to the sound and light alarm device and the light flashing device. The controller module also synchronizes information with the microcomputer five-protection locking system. If the five-protection key has entered the operation instruction, the controller module will synchronize the light flashing reminders before and after the switch cabinet that needs to be operated to assist the operator to confirm the operation target.

[0069] Specifically, the present invention provides an audio and visual warning device for stopping power supply when a switch in a distribution room is operated, and the controller module is also used for:

[0070] Receive the actual demand for switch operation in the distribution room, and determine the indicators that need to be monitored and warned according to the actual demand for switch operation in the distribution room. The indicators for monitoring and warning include switch status, current and voltage abnormalities, operation time interval, and personnel approach distance;

[0071] Retrieve historical operation data and fault records from preset data. Historical operation data includes data under normal operation and abnormal conditions.

[0072] Preprocess historical operation data and fault records, use machine learning based on monitoring and early warning indicators and the preprocessed historical operation data and fault records to obtain an early warning analysis model, and use historical data to verify the early warning model.

[0073] Specifically, the design and function realization of the controller module of the sound and light warning device for power outage caused by switch operation in a power distribution room provided by the present invention are particularly critical, and are described in detail as follows:

[0074] The controller module is responsible for receiving data transmitted from the sensor module, which monitors the status of the switch in the distribution room in real time, including the current status of the switch, operation timestamp, current and voltage values, etc. After receiving the data, the controller module immediately parses the data for subsequent processing.

[0075] The controller module matches and compares the parsed data with the preset safety standards or operating rules. This step is crucial, as it is used to determine whether the current switch status meets expectations and whether the operating time is within the allowable range. Through this comparison, the controller module can initially identify whether there is a potential danger or risk of misoperation.

[0076] Based on the results of data matching and comparison, the controller module conducts further risk assessment. If the assessment results show that there is a dangerous switchgear or that special attention is needed, the controller module will match the corresponding decision based on the preset knowledge base. The knowledge base contains various dangerous situations and corresponding countermeasures, which enables the controller module to make the right decision, that is, to activate the sound and light alarm device and the light flashing device to alert the operator.

[0077] In addition, the controller module also uses the preset early warning model to conduct in-depth analysis of the switch status data in the distribution room. The early warning model is built and verified by machine learning algorithms based on historical operation data and fault records. It can more accurately identify potential dangers or misoperation risks and generate early warning analysis results. If the early warning analysis results are dangerous, the controller module will immediately activate the sound and light alarm device and the light flashing device to remind the operator in both sound and light forms.

[0078] While sending early warning instructions to the sound and light alarm device and the light flashing device, the controller module also synchronizes information with the microcomputer five-protection locking system. This step improves the accurate transmission of operation instructions, allowing the sound and light warning device and the microcomputer five-protection locking system to work closely together to ensure the safety of the power system. If the five-protection key has entered the operation instruction, the controller module will also synchronize the light flashing reminders before and after the switch cabinet that needs to be operated to assist the operator to accurately confirm the operation target and avoid going to the wrong interval or misoperation.

[0079] Finally, in order to continuously improve the accuracy and reliability of early warning, the controller module can also determine the indicators that need to be monitored and warned, including switch status, current and voltage abnormalities, operation time intervals, and personnel approach distance, etc., according to the actual needs of the switch operation in the distribution room. By retrieving historical operation data and fault records in the preset data, and preprocessing and machine learning the data, the controller module can continuously optimize and update the early warning model to adapt to different operating environments and needs.

[0080] In summary, the controller module of the present invention effectively solves the problem of easy wrong interval and high risk of misoperation in power outage operation of the power system through real-time monitoring, intelligent analysis, sound and light alarm and flashing light reminder, and close synchronization with the microcomputer five-protection locking system. At the same time, by continuously optimizing and updating the early warning model, the present invention can also adapt to different operating environments and requirements, providing a strong technical guarantee for the safe and stable operation of the power system.

[0081] Specifically, the sound and light warning device for power supply stoppage caused by switch operation in a power distribution room provided by the present invention, the microcomputer five-protection locking system synchronization module is also used for:

[0082] The microcomputer five-protection locking system synchronization module receives operation instructions, parses and identifies the instructions, and generates synchronization information based on the parsed operation instructions. The synchronization information generated by the microcomputer five-protection locking system synchronization module includes the identification of the switch cabinet that needs to be operated, the operation type, and the light flashing reminder instruction.

[0083] The synchronization module of the microcomputer five-protection locking system sends the generated synchronization information to the light flashing device. After receiving the synchronization information, the light flashing device flashes the lights in synchronization with the switch cabinets that need to be operated according to the instructions.

[0084] Specifically, the sound and light warning device for power supply stoppage caused by switch operation in a power distribution room provided by the present invention, the microcomputer five-protection locking system synchronization module is also used for:

[0085] The synchronization module of the microcomputer five-protection interlocking system parses the received operation instructions and extracts the switch cabinet information of the operation object, the closing information of the operation type, and the opening information of the operation type;

[0086] Match the parsed operation instruction with the switch cabinet information in the system to obtain the switch cabinet identification corresponding to the operation instruction;

[0087] According to the matching results, the synchronization module of the microcomputer five-protection locking system generates synchronization information, which includes the identification of the switch cabinet that needs to be operated, the operation type, and the instruction of the light flashing reminder.

[0088] Specifically, the core component of the sound and light warning device for power outage in the switch operation of the distribution room provided by the present invention, the controller module, undertakes the important tasks of data processing, risk assessment and warning instruction issuance. The detailed functions are described as follows:

[0089] The controller module is responsible for receiving real-time data transmitted from the sensor module, covering key information such as the current status of the switch in the distribution room, operation timestamps, and current and voltage values. After receiving the data, the controller module immediately starts the data parsing program to convert the raw data into a format that can be processed and analyzed later.

[0090] The controller module accurately matches and compares the parsed data with the preset safety standards or operating rules. The purpose of this step is to determine whether the current switch state meets expectations and whether the operating time is within the specified allowable range. Through this comparison process, the controller module can preliminarily screen out switchgear that is dangerous or requires special attention.

[0091] Based on the results of data matching and comparison, the controller module further conducts a hazard assessment. If the assessment results show that there is a dangerous switch cabinet or that requires immediate operation, the controller module will quickly match the corresponding decision-making plan based on the preset knowledge base. The knowledge base is a database that integrates various dangerous situations and corresponding response measures. It enhances the controller module's ability to make correct and rapid responses in emergency situations, that is, to activate the sound and light alarm device and the light flashing device to alert the operator in a striking way.

[0092] In addition, the controller module also has advanced data analysis capabilities. It can substitute the switch status data of the distribution room into the preset early warning model for processing. The early warning model is based on a large amount of historical operation data and fault records, and is built and verified by advanced machine learning algorithms. It can deeply analyze the data, accurately determine whether there are potential dangers or risks of misoperation, and generate detailed early warning analysis results. If the early warning analysis results are dangerous, the controller module will immediately trigger an audible and visual alarm and flashing lights to maximize the safety of operators.

[0093] While sending early warning instructions to the sound and light alarm device and the light flashing device, the controller module also closely synchronizes information with the microcomputer five-protection locking system. This step improves the accuracy and timely transmission of operating instructions, allowing the sound and light warning device and the microcomputer five-protection locking system to work together to build a safety line of defense for the power system. If the five-protection key has entered the operating instruction, the controller module will also intelligently flash the lights in front and behind the switch cabinet that needs to be operated to assist the operator to accurately and quickly confirm the operation target and avoid going to the wrong interval or making a wrong operation.

[0094] In order to meet the actual needs of switch operations in different distribution rooms, the controller module also has flexible configuration capabilities. It can determine the indicators that need to be monitored and warned according to actual needs, such as switch status, current and voltage abnormalities, operation time intervals, and personnel approach distances. By retrieving historical operation data and fault records in preset data, and preprocessing and machine learning the data, the controller module can continuously optimize and update the warning model, improve the accuracy and reliability of the warning, and thus adapt to different operating environments and needs.

[0095] In summary, the controller module of the present invention constructs a complete and efficient sound and light warning system for power outage in the distribution room switch operation through real-time monitoring, intelligent analysis, sound and light alarm and flashing light reminder, and close synchronization with the microcomputer five-protection locking system. The system not only effectively solves the problem of easy wrong interval and high risk of misoperation in power outage operation of the power system, but also improves the adaptability and accuracy of the system by continuously optimizing and updating the early warning model, providing a strong technical guarantee for the safe and stable operation of the power system.

[0096] The technical solution of the present invention solves the problem of going to the wrong interval and reducing the risk of misoperation during power outage and transmission operation of the power system in the following ways:

[0097] The sensor module in the present invention can monitor the status of the switch in the distribution room in real time. When the switch operation occurs, the sensor will immediately collect relevant data and transmit it to the controller module. After receiving the data, the controller module performs preprocessing and substitutes it into the preset early warning model for data processing. The early warning model is constructed based on historical data and fault records using machine learning and other methods, and can accurately determine whether the current operation is dangerous.

[0098] If the early warning analysis results indicate that there is a danger, the controller will immediately activate the sound and light alarm device and the light flashing device to alert the operator in the form of sound and light to avoid misoperation.

[0099] After receiving the warning command from the controller, the sound and light alarm device will convert the warning command into a sound control command and perform a sound broadcast to remind the operator by sound. At the same time, the light flashing device will also receive the warning command from the controller and convert the warning command into a light control command to realize the light display. The light flashing device will flash the lights synchronously before and after the switch cabinet that needs to be operated according to the command to assist the operator to confirm the operation target in a visual way.

[0100] The present invention also provides a microcomputer five-protection locking system synchronization module, which is used to synchronize the sound and light warning system with the microcomputer five-protection locking system. When the operator uses the five-protection key to enter the operation instruction in the microcomputer five-protection locking system, the microcomputer five-protection locking system synchronization module will receive the instruction, parse and identify the instruction, and generate synchronization information according to the parsed operation instruction. The synchronization information includes the identification of the switch cabinet that needs to be operated, the operation type, and the instruction of the flashing light reminder, which improves the operator's ability to accurately identify the switch cabinet that needs to be operated when performing the power outage operation to avoid going to the wrong interval.

[0101] Through real-time monitoring, early warning analysis, sound and light alarms and flashing reminders, as well as synchronization with the microcomputer five-protection locking system, the present invention constructs a complete protection system. The protection system can remind operators to pay attention to the current operating environment and operating objectives in all directions, thereby effectively reducing the risk of misoperation and ensuring the safe and stable operation of the power system.

[0102] In summary, the technical solution of the present invention effectively solves the problem of going to the wrong interval during power outage operations and reduces the risk of misoperation through real-time monitoring, early warning analysis, sound and light alarms and flashing light reminders, and synchronization with the microcomputer five-protection locking system.

Thus, if the modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include the modifications and variations, and the above-described embodiments of the present invention do not constitute a limitation on the scope of protection of the present invention.
