Description

Technical Field

[0001] The present invention relates to the field of urban management and power safety technology, and specifically to an urban flooding electric shock risk warning device suitable for a smart city management system. Background Art

[0002] Waterlogging refers to the accumulation of water in some parts of a city due to heavy rain or poor drainage systems. The water cannot be discharged in time, thus flooding roads or facilities. Urban waterlogging not only damages infrastructure such as transportation and buildings, but may also cause electrical equipment or public facilities to be electrified, posing a risk of electric shock and threatening the lives of citizens.

[0003] Traditional urban management systems mainly rely on manual inspections and emergency responses, and it is difficult to perceive and effectively protect against the risk of electric shock caused by waterlogging in advance, especially in waterlogged areas, where the risk of electric shock cannot be identified in time due to power supply facilities, street lamp poles, public charging equipment, etc. The specific problems or shortcomings of traditional urban management systems are as follows:

[0004] (1) Unable to identify electric shock hazards in real time: The existing system mainly relies on manual inspections, which makes it difficult to timely identify the risk of electric shock in water-related areas of power facilities caused by flooding.

[0005] (2) Lack of local alarm and personnel reminder functions: Traditional systems are unable to immediately remind on-site personnel to avoid danger when electric shock hazards occur.

[0006] (3) Warning information cannot be transmitted to the competent authority in a timely manner: The existing system is unable to quickly upload warning information of electric shock accidents to the management department, resulting in untimely emergency response.

[0007] (4) Insufficient power supply and poor system reliability: Existing technologies are prone to equipment failure and cannot continue to work during power outages or severe weather.

[0008] With the development of smart city management systems, the combination of Internet of Things technology, sensor technology and urban management platforms can monitor the status of urban electrical equipment in real time, identify risks in a timely manner and issue warnings to reduce the possibility of accidents. Therefore, the development of an early warning device for electric shock risk caused by waterlogging in smart cities has important social significance and economic benefits. Summary of the invention

[0030] The waterlogging electric shock risk warning device for smart urban management of the present invention can be implemented through the following module functions:

[0031] (1) Detection module: It consists of an electric field sensor and a humidity sensor, which monitors the electric field strength of the target area in real time and transmits it to the data processing module through a signal cable.

[0032] The electric field induction trigger condition is: V induced = k·E current ;

[0033] Among them, V induced is the voltage signal sensed by the inductive pen, k is the inductance, E current is the current electric field strength; when V induced Exceeds the set threshold V threshold , that is, V induced ≥V threshold , the system determines that the device is energized and triggers an alarm.

[0034] (2) Data processing module: This module filters, amplifies and analyzes the signal from the detection module to determine whether there is a risk of electric shock. When abnormal electric field fluctuations are detected and the induced potential caused by the electric field changes exceeds the preset threshold, the data processing module issues an alarm signal.

When the equipment detects abnormal voltage or electric field fluctuations, combined with water, it determines that there may be a risk of electric shock.

[0042] (2) Data processing and analysis: The data processing module performs real-time analysis on the signal. When abnormal data exceeding the safety threshold is detected, the system triggers an early warning mechanism.

[0043] (3) Alarm and warning: The alarm module immediately issues an on-site sound and light alarm to remind personnel of the risk of electric shock. At the same time, the alarm information is uploaded to the smart urban management platform through the communication module.

[0045] (5) Multiple power supply guarantees: The equipment supports AC power, solar energy and battery power supply to ensure that the device can continue to work under extreme conditions and avoid monitoring blind spots caused by power outages.

[0046] 3. Application scenarios of the present invention

[0048] (2) Protection of power facilities: The equipment can be installed around electrical facilities such as street lamps and traffic lights to prevent live equipment from causing harm to the surrounding environment due to waterlogging.

[0049] (3) Smart Urban Management System: Cooperate with the smart urban management cloud platform to form a complete urban flooding electric shock warning and emergency response system to reduce the incidence of electric shock accidents.

[0050] 4. Examples of implementation methods of other embodiments of the present invention

[0051] (1) In addition to using a voltage sensor, the detection module can also adopt the following implementation methods:

[0052] A. Current sensor: Use current sensor to detect whether there is abnormal current in the equipment, so as to determine whether there is a risk of electric shock.

[0053] B. Electromagnetic field sensor: Electromagnetic field sensor is used to monitor the changes in the electromagnetic environment around the equipment and determine whether the power facilities are energized.

[0054] C. Infrared imaging sensor: Use infrared sensors to detect abnormal changes in the surface temperature of power equipment, indirectly determine whether there is current leakage or overheating of power equipment, and indicate potential electric shock hazards.

[0055] (2) In addition to using sound and light alarms and voice alarms, the alarm module can also use the following implementation methods:

[0056] A. Vibration alarm: Based on the original sound and light alarm, a vibration alarm device is added to remind people with hearing or visual impairments.

[0057] B. Remote alarm equipment: In addition to local sound and light alarms, wireless alarm devices can also be added to send alarm information directly to nearby portable devices or wearable devices such as mobile phones and smart watches via wireless signals.

[0058] C. Visual marking: As an alternative, laser pointers or other visual markings such as projections can be used to directly delineate the danger zone and further alert on-site personnel.

[0059] (3) The communication module can also be implemented in the following manner:

[0060] Satellite communication: In areas where wireless communication is limited or signal coverage is insufficient, satellite communication is used as a backup communication method to ensure the stability of data transmission.

[0061] Bluetooth or Zigbee technology: Data can be transmitted over short distances using Bluetooth or Zigbee technology, which is suitable for short-distance communication applications.

[0062] Wired fiber optic communication: In scenarios where data transmission stability is extremely high, fiber optic communication can be used to improve data transmission speed and anti-interference capabilities.

[0063] (4) The power supply module can also adopt the following implementation methods:

[0064] Wind power supply: In an environment with wind resources, a small wind turbine is added as a power backup, which is especially suitable for outdoor or windy scenes.

[0065] Hydropower supply: In the case of waterlogging or waterlogging, micro hydroelectric power generation devices can be used to power equipment through water flow, which is particularly suitable for environments with long-term waterlogging.

[0066] Thermoelectric power supply: By installing a thermoelectric converter on the surface of the device, the temperature difference is used to generate electricity to provide supplementary power for the device.

[0067] (5) The present invention adopts a modular design for easy upgrading and maintenance. In addition, all functional modules can be integrated into one device to reduce the space occupied by the device, which is suitable for scenarios with high volume requirements; or different modules can be distributed to different areas, and each area can communicate with each other by wireless or wired means, which is suitable for application scenarios that need to cover a large area.

[0068] 5. Comparison between the present invention and the prior art:

[0069] (1) The existing technology cannot identify the hidden danger of electric shock in real time and mainly relies on manual inspections, which makes it difficult to timely identify the risk of electric shock in water-related areas of power facilities caused by waterlogging. The present invention uses an intelligent detection module to monitor the electrical status of power facilities and surrounding water bodies in real time. When a hidden danger of electric shock is detected, it immediately responds and issues an early warning.

[0070] (2) The existing technology lacks local alarm and personnel reminder functions, and cannot immediately remind on-site personnel to avoid danger when electric shock hazards occur. The present invention uses the voice prompt function of the alarm module. When the risk of electric shock is detected, an audible and visual alarm is immediately issued on site, and voice prompts are used to remind nearby personnel not to approach the dangerous area, thereby reducing the occurrence of electric shock accidents.

[0071] (3) The existing technology cannot quickly and timely transmit the warning information of electric shock accidents to the competent authorities, resulting in an untimely emergency response. The present invention uploads the alarm signal to the smart urban management platform or relevant competent authorities in real time through the communication module, ensuring that the management department can receive the warning information in time and quickly take emergency measures to improve the efficiency of emergency response.

[0072] (4) The existing technology has insufficient power supply guarantee and poor system reliability. In the event of a power outage or bad weather, the equipment is prone to failure and cannot continue to work. The present invention adopts a multiple power supply design, including mains power, battery and solar power, to ensure that the equipment can still operate normally in various harsh environments and continue to monitor and warn.

[0073] The specific embodiments described above are merely illustrative examples of the present invention, and do not limit the present invention to be implemented only through the aforementioned embodiments. Based on the embodiments listed in the present invention, all other embodiments that can be obtained by ordinary technicians in this field without making creative efforts belong to the protection scope of the present invention.
