Specification

Description:FIELD OF DISCLOSURE
[0001] The present disclosure generally relates to emergency response systems, more specifically, relates to a smart emergency response system based on GPS-enabled accident alerts and automated traffic light control for ambulances.
BACKGROUND OF THE DISCLOSURE
[0002] Emergency response systems are essential frameworks designed to efficiently manage and coordinate responses to critical incidents, such as accidents, natural disasters, medical emergencies, and public safety threats. These systems integrate various technologies and communication protocols to facilitate real-time information exchange among emergency services, such as police, fire, and medical personnel, as well as with the public. The effectiveness of these systems is vital for saving lives, preventing damage, and ensuring community safety, highlighting their importance in emergency response and disaster preparedness.
[0003] Conventional emergency response systems exhibit several limitations in effectively managing traffic flow and handling emergency situations. One major disadvantage is their inability to dynamically adjust signal timings based on real-time traffic conditions. These systems rely on pre-set timing cycles, leading to unnecessary waiting times for vehicles at intersections, even during periods of low traffic. This inflexibility also limits the ability to maximize the distance traveled by vehicles during green light intervals, resulting in inefficient traffic flow, increased fuel consumption, and heightened congestion. Moreover, the conventional systems lack a mechanism to prioritize emergency vehicles like ambulances, which causes delays in clearing paths for these vehicles during critical situations, potentially compromising emergency response efforts and public safety.
[0004] Another key limitation is the lack of integration with modern communication systems in conventional systems. Traditional systems are not equipped with advanced communication interfaces which restricts their ability to coordinate with emergency centers or contacts in real-time. This deficiency hampers their ability to relay vital information about traffic conditions and emergencies, preventing timely and efficient action. Additionally, the fixed green light switching intervals do not adapt to changing traffic densities, causing inefficient signal switching at intersections. This rigidity results in prolonged waiting periods and increased switching frequency, contributing to traffic congestion and inefficiencies. These limitations collectively highlight the need for a more adaptive and communication-enabled solution to improve traffic management and emergency response.
[0005] The present invention addresses the limitations of the prior art by introducing a smart emergency response system that dynamically modifies traffic signals based on real-time data, prioritizes the passage of emergency vehicles, and incorporates advanced communication technologies for enhanced coordination. Through the integration of these communication mechanisms and real-time monitoring capabilities, the present invention significantly improves traffic efficiency and minimizes delays, ultimately strengthening public safety and emergency response times. The present invention is more efficient than conventional systems by minimizing waiting times, enhancing vehicle travel distances, and ensuring reliable operation during emergencies through the use of GSM communication. Integrating GSM and advanced communication technologies enable reliable interaction between emergency response units, ensuring swift responses and minimizing operational delays.
[0006] Thus, in light of the above-stated discussion, there exists a need for a smart emergency response system.

[0043] Referring now to FIG. 1 to FIG. 4 to describe various exemplary embodiments of the present disclosure. FIG. 1 illustrates a block diagram of a smart emergency response system 100, in accordance with an exemplary embodiment of the present disclosure.
[0044] The system 100 may include a vehicle unit 102, an ambulance unit 108, and a traffic management unit 112.
[0045] The vehicle unit 102 is integrated into a vehicle and is responsible for detecting accidents and transmitting accident location data to an emergency center 106. The vehicle unit 102 interfaces with an impact sensor 114, an accelerometer 116, a location detector 118, a communication unit 120 and a first microcontroller 122 to gather necessary data for accurate accident detection and to trigger the emergency response.
[0046] The impact sensor 114 is designed to detect sudden changes in force when the vehicle experiences a collision. It measures the abrupt deceleration or acceleration caused by the impact. The impact sensor 114 is essential for determining whether an accident has occurred, triggering the emergency response of the system 100.
[0047] The accelerometer 116 is used to sense changes in the vehicle's velocity, as well as detect linear acceleration forces. By measuring the rate of change in velocity, the accelerometer 116 can detect even minute forces that could indicate a collision or accident. The accelerometer 116 complements the impact sensor 114 by providing additional data for accident detection, especially in cases where the impact may not produce significant force but still results in an accident. In one embodiment of the present invention, the accelerometer 116 is an ADXL335, an electromechanical device capable of providing complete 3-axis acceleration measurements.
[0048] The location detector 118 is a GPS-based device that is connected to the impact sensor 114 and the accelerometer 116. Once the vehicle unit 102 determines that an accident has occurred, the location detector 118 locates the coordinates of the accident. It provides geographic data that helps emergency responders locate the accident vehicle quickly. The location detector 118 works by interfacing with GPS satellites to gather accurate position data.
[0049] The communication unit 120 is responsible for transmitting the accident location data to the emergency center 106. The communication unit 120 uses a communication network 104 to send real-time information about the accident. It ensures that the emergency center is informed immediately and can begin dispatching assistance without delay. In one embodiment of the present invention, the communication unit utilizes GSM (Global System for Mobile Communications) technology that allows mobile devices to communicate, to transmit accident location data from the vehicle unit 102 to the emergency center 106. By leveraging the widespread GSM network, the communication unit 120 ensures reliable and real time data transmission across long distances.
[0050] The first microcontroller 122 is responsible for processing data received from the impact sensor 112 and the accelerometer 116 to determine whether an accident has occurred. The role of the first microcontroller 122 is to make decisions based on the data received from the sensors, triggering actions such as sending location data to the emergency center and activating alert mechanisms. The first microcontroller 122 comprises several modules that work together to manage accident detection. These modules include a data input module 130, a data processing module 132, a location fetching module 134, a first activation module 136, and a transmission module 138.
[0051] The data input module 130 receives input data from the impact sensor 114 and the accelerometer 116. It gathers the raw data generated by these sensors and prepares it for processing. The data processing module 132 analyzes the data received from the data input module 130 to determine whether the vehicle has been involved in an accident. The data processing module 132 applies algorithms to the raw data, detecting specific patterns or thresholds that correspond to an accident. It plays a crucial role in minimizing false alarms and ensuring that the system 100 only activates when an actual accident occurs. Once the data processing module 132 determines that an accident has occurred, the location fetching module 134 retrieves the coordinates of the accident location from the location detector 118. The location fetching module 134 activates when an accident is detected, ensuring that the vehicle's exact location is communicated to the emergency center 106. Once the location coordinates are identified, the location fetching module 134 also triggers an activation signal to initiate further response actions. The first activation module 136 is responsible for triggering various alert mechanisms in the vehicle unit 102. Once an accident is detected, the first activation module 136 activates a first display 124 to show the real time location coordinates of the accident and a first buzzer 126 to emit audible alerts.
[0052] The first display 124 is used to show the real time location coordinates of the accident. The first display 124 helps the vehicle occupants track the status of the accident alert and provides immediate information to assist emergency responders. It visually communicates the current location of the accident, which is vital for dispatching help to the correct location.
[0053] In one embodiment of the present invention, the first buzzer 126 is configured to alert nearby individuals upon detection of an accident. The first buzzer 126 is an audible alert device that notifies individuals in the vicinity of the vehicle's collision, providing an immediate warning to facilitate prompt assistance or caution. The first buzzer 126 is activated by the first microcontroller 122 upon confirmation of an accident, providing an audible alert to signal the incident. By emitting a loud sound, the first buzzer 126 ensures that those nearby are aware of the situation and can take appropriate actions, such as notifying emergency services or providing aid to the accident victims.
[0054] The transmission module 138 is responsible for transmitting the fetched location data and a SOS message to the communication unit 120. After determining that an accident has occurred and fetching the accident coordinates, the transmission module 138 ensures that the accident location data is sent to the emergency center 106 in real time. The transmission module 138 plays a pivotal role in ensuring the emergency center 106 is informed promptly, allowing for a rapid response.
[0055] The ambulance unit 108 is another important unit of the system 100 which is integrated into an ambulance to facilitate prompt and efficient routing of the ambulance to an accident location by coordinating with the emergency center 106. The ambulance unit 108 is designed to indicate the road from which the ambulance will arrive, directing the transmission of signals accordingly via a second communication network 110 to the traffic management unit 112 and prompt any necessary adjustments in signal control. This coordination enables clear pathways for the ambulance and faster response times.
[0056] The traffic management unit 112 is another key unit of the system 100 which is designed to monitor traffic density on multiple lanes and for real time data processing. The traffic management unit 112 evaluates the flow of traffic and processes incoming signals from the approaching ambulances, allowing the system 100 to dynamically adjust traffic light phases and lane priorities to facilitate swift ambulance passage while minimizing disruptions to regulate traffic flow.
[0057] In one embodiment of the present invention, the vehicle unit 102, the ambulance unit 108, and the traffic management unit 112 are each further provided with a first power source 128, a second power source 208, and a third power source 314, respectively, to ensure continuous operation of all components.
[0058] FIG. 2 illustrates a block diagram of the ambulance unit 108, in accordance with an exemplary embodiment of the present disclosure.
[0059] The ambulance unit 108 includes various components that work together to facilitate efficient routing to accident locations and communicate with the traffic management unit 112 for uninterrupted passage. The ambulance unit 108 comprises a first body 200, which houses various components including switches 202,204, a RF transmitter 206, and a second power source 208. The switches 202,204 are configured to allow the ambulance operators to indicate the lane from which the ambulance is approaching, enabling accurate directional signalling. In one embodiment of the present invention, the switches 202,204 comprise a first switch 202 configured to activate when the ambulance is approaching from a first lane, and a second switch 204 configured to activate when the ambulance is approaching from a second lane. The first switch 202 and the second switch 204 enable the system 100 to dynamically direct traffic signals and control the flow of vehicles based on the ambulance's route, ensuring minimal delays and a clear path for emergency response.
[0060] In one embodiment of the present invention, the system 100 further comprises an RF transmitter 206 integrated into the ambulance unit 108 to continuously transmit signals indicating the approach of the ambulance and an RF receiver 310 integrated into the traffic management unit 112 to receive signals from the ambulance unit 108 via a second communication network 110. The ambulance unit 108 contains the RF transmitter 206, which sends signals to the traffic management unit 112 to alert it of the approaching emergency vehicle. This feature helps prioritize traffic lanes by modifying traffic light sequences, ensuring a clear and expedited route for the ambulance.
[0061] The ambulance unit 108 is further equipped with a second power source 208, which supplies power to various components within the ambulance unit 108 to ensure consistent operation during emergency responses. This dedicated power source helps maintain functionality even under demanding conditions, supporting reliable communication and signalling. In one embodiment of the present invention, the second power source 208 is a 9V battery, chosen for its portability and sufficient voltage capacity to power essential elements like switches 202,204, and communication modules within the ambulance unit 108.
[0062] FIG. 3 illustrates a block diagram of the traffic management unit 112, in accordance with an exemplary embodiment of the present disclosure.
[0063] The traffic management unit 112 is designed to monitor traffic density on two specific road lanes and control traffic lights 320,322 to facilitate smooth passage for emergency vehicles like ambulances. The traffic management unit comprises of a second body 300, housing various components including a plurality of sensor 302-308, an RF receiver 310, a second microcontroller 312, a third power source 314, a second display 316, a second buzzer 318, and traffic lights 320,322. In one embodiment of the present invention, the traffic lights 320,322 comprises a first traffic light 320 positioned on a first lane and a second traffic light 322 positioned on a second lane. The traffic management unit 112 includes various components that work in coordination to effectively manage and control traffic flow, especially during emergency situations.
[0064] The traffic management unit 112 is equipped with the plurality of sensor 302-308, which are strategically placed on the two specific road lanes to continuously monitor traffic density. By gathering real time data on vehicle density, the plurality of sensor 302-308 provide critical input for traffic management, enabling the system 100 to assess congestion levels. In one embodiment of the present invention, the plurality of sensor 302-308 are infrared sensors. By emitting infrared light and measuring the reflection from objects, the plurality of sensor 302-308 can accurately detect vehicles in their respective lanes. The infrared sensors are chosen for their reliability, low maintenance, and capability to function effectively in various environmental conditions, including low light or night time scenarios.
[0065] In one embodiment of the present invention, the plurality of sensor 302-308 comprises four sensors including a first sensor 302 positioned on the first lane and configured to activate the green light of the first traffic light 320 for 8 seconds when minimum traffic is detected on the first lane, a second sensor 304 positioned on the first lane and configured to extend the green light of the first traffic light 320 to 12 seconds when higher traffic density is detected on the first lane, a third sensor 306 positioned on the second lane and configured to activate the green light of the second traffic light 322 for 8 seconds when minimum traffic is detected on the second lane, and a fourth sensor 308 positioned on the second lane and configured to extend the green light of the second traffic light 322 to 12 seconds when higher traffic density is detected on the second lane.
[0066] The traffic management unit 112 further comprises the RF receiver 310 which receives signals from the ambulance unit 108, indicating which lane should be prioritized.
[0067] Data from the plurality of sensor 302-308 and the RF receiver 310 is effectively transmitted to the second microcontroller 312 which plays a central role in the traffic management unit 112 for data processing and traffic management. This second microcontroller 312 is equipped with several modules to facilitate its functions including a data input module 324, a signal processing module 326, a priority module 328, a traffic control module 330, and a second activation module 332 . The data input module 324 is responsible for receiving the raw input data from each of the plurality of sensor 302-308, allowing it to gather information on traffic density across different lanes. This data input module 324 ensures that all relevant data reaches the second microcontroller 312 for further processing.
[0068] The signal processing module 326 is tasked with processing the incoming signals received from the ambulance as well as the data received from the plurality of sensor 302-308. The signal processing module 326 analyzes traffic density on each lane, helping to determine congestion levels and making it possible to allocate the traffic signals 320,322 effectively.
[0069] The priority module 328 then uses this processed data to assign lane priorities, based on both ambulance signals and detected traffic density. This ensures that lanes with higher emergency needs or more traffic receive appropriate priority.
[0070] The traffic control module 330 dynamically adjusts the timing and sequencing of the traffic lights 320, 322 based on insights from the priority module 328. The traffic control module 330 manages the flow of vehicles, enabling the ambulance to move through congested areas with minimal delay. Upon the arrival of an ambulance, the traffic management unit 112 is configured to prioritize the ambulance's lane, and toggle the traffic lights 320,322 accordingly to ensure its smooth passage. In one embodiment of the present invention, the traffic management unit 112 prioritizes the road lane with greater traffic density and toggles the traffic lights 320,322 based on priority until traffic congestion is cleared.
[0071] The second activation module 332 activates the second display 316 to show real time traffic information, including lane priority statuses, providing awareness for all road users. Additionally, it activates the second buzzer 318 to produce audible alerts. In one embodiment of the present invention, the second buzzer 318 is configured to provide an audible alert to road users when the ambulance is approaching, signaling changes in traffic flow and priority adjustments, ensuring that drivers are aware of emergency routing.
[0072] The traffic management unit 112 is further provided with a third power source 314 which provides a regulated power supply to ensure continuous operation of all components of the traffic management unit 112, allowing consistent monitoring, response, and prioritization in emergency situations.
[0073] In one embodiment of the present invention, the first microcontroller 122 and the second microcontroller 312 are of the STM32 type, which is a 32-bit microcontroller used to perform and control all the operations of the vehicle unit 102 and the traffic management unit 112, respectively.
[0074] In one embodiment of the present invention, the first display and the second display are 16x2 LCD displays, used to present relevant information.
[0075] In an exemplary embodiment, if an operator activates the first switch 202 of the ambulance unit 108, the traffic management unit 112 receives the signal indicating that the ambulance is approaching from the first lane. Upon receiving this signal, the system 100 processes traffic density data from the plurality of sensor 302-308 and adjusts the first traffic light 320 to remain green for an extended period, ensuring the uninterrupted passage of the ambulance. In contrast, if an operator activates a second switch 204 of the ambulance unit 108, the traffic management unit 112 receives the signal indicating that the ambulance is approaching from the second lane. Upon receiving this signal, the system 100 processes traffic density data from the plurality of sensor 302-308 and adjusts the second traffic light 322 to remain green for an extended duration, allowing the ambulance to pass through the intersection smoothly.
