Abstract
Description
Technical Field
[0001] This application relates to the field of fire emergency evacuation, and in particular to an evacuation guidance system with an emergency call function. Background Technology
[0002] Evacuation guidance systems with emergency call functions fall under the field of fire safety equipment. With socio-economic development and accelerated urbanization, the height and complexity of buildings are constantly increasing, leading to a greater risk of fire accidents. To ensure the safety of people and improve the efficiency of emergency response in fire situations, the development of evacuation guidance systems has become a crucial issue in the field of fire safety.
[0003] In most buildings, evacuation guidance systems are installed to automatically indicate evacuation directions based on the progress of a fire, facilitating escape and rescue. However, in real-life fires, dense smoke and extremely poor visibility, especially in crowded public places, can lead to blocked escape / evacuation routes, incorrect escape directions, or changes in escape routes depending on the fire's development. Furthermore, limited mobility may prevent people from escaping and necessitate waiting for rescue. Particularly in public places, trapped individuals may be unfamiliar with the location and layout, and even with a mobile phone, they may be unable to clearly state their location. This uncertainty about the number and location of trapped individuals hinders firefighting efforts, misses crucial rescue opportunities, and threatens the safety of firefighters. Therefore, quickly locating ordinary citizens indoors has become a pressing technical problem that needs to be solved. Utility Model Content
[0004] In order to quickly locate ordinary people indoors, this application provides an evacuation guidance system with an emergency call function.
[0005] This application provides an evacuation guidance system with emergency call function, which adopts the following technical solution:
[0006] An evacuation guidance system with emergency call function includes:
[0007] An evacuation indicator light includes a distress call module, a microprocessor, and a communication module. The microprocessor is connected to both the distress call module and the communication module. The distress call module generates a distress signal, and the microprocessor identifies the distress signal from the distress call module. Upon identifying the distress signal, the microprocessor obtains the encoded address of the evacuation indicator light and sends the encoded address to the communication module. The communication module transmits the received encoded address of the evacuation indicator light and the distress signal.
[0008] An evacuation indicator controller is located in the fire control room. The evacuation indicator controller is connected to the communication module and is used to receive the coded address of the evacuation indicator light and the distress signal sent by the communication module, and to display the coded address and distress signal so that the fire personnel in the fire control room can carry out rescue according to the indicator information.
[0009] By adopting the above technical solution, the evacuation indicator light integrates a distress signal module. Therefore, in emergencies, ordinary citizens in dangerous areas can easily trigger a distress signal without needing to find other specialized distress equipment, improving the timeliness and convenience of distress calls. When a distress signal is triggered, the microprocessor obtains the coded address of the evacuation indicator light and sends this information through the communication module. The coded address of the evacuation indicator light is unique, enabling firefighters in the fire control room to quickly and accurately locate the person calling for help, providing crucial information for rapid rescue. This further improves rescue efficiency.
[0010] Preferably, the distress signal includes a first distress signal and a second distress signal, and the distress module includes a button unit and / or a Bluetooth unit;
[0011] The button unit is placed on the evacuation indicator light and is used to generate a first distress signal when the button unit is pressed.
[0012] The Bluetooth unit is placed inside the evacuation indicator light and is used to generate a second distress signal when the Bluetooth unit is connected to the Bluetooth carried by the mobile terminal.
[0013] By adopting the above technical solution, the distress signal module includes a button unit and / or a Bluetooth unit. The button unit is located on the evacuation indicator light; pressing the button generates a first distress signal. The Bluetooth unit allows users to establish a Bluetooth connection with the evacuation indicator light via a mobile terminal (such as a mobile phone), thereby generating a second distress signal. Whether via the button unit or the Bluetooth unit, the microprocessor can quickly receive the distress signal and send the indication information to the evacuation indicator controller through the communication module. This not only improves the transmission efficiency of the distress signal but also ensures the accuracy of the information, enabling firefighters to locate trapped civilians more quickly.
[0014] Preferably, the button unit adopts a capacitive touch method.
[0015] By adopting the above technical solution, capacitive touch buttons have no physical contacts compared to traditional mechanical buttons, thus reducing wear and malfunctions caused by prolonged use or frequent pressing. At the same time, capacitive touch buttons have better sealing performance, which can effectively prevent the intrusion of moisture and dust.
[0016] Preferably, the evacuation indicator controller is also connected to a fire alarm system to receive fire alarm signals sent by the fire alarm system, generate evacuation indicator control information after receiving the fire alarm signal, and send the fire alarm signal and the generated evacuation indicator control information to the evacuation indicator light.
[0017] By adopting the above technical solution, the connection between the evacuation indicator controller and the fire alarm system realizes information sharing and linkage between the two systems, so that when a fire occurs, the evacuation indicator controller can quickly receive the fire alarm signal and send the fire alarm signal to the evacuation indicator light accordingly.
[0018] Preferably, the evacuation indicator light further includes a voice module, which is placed inside the evacuation indicator light and is used to issue a first voice prompt after receiving an alarm signal sent by the evacuation indicator controller. The first voice prompt is used to prompt the trapped person to press the button unit and / or prompt the trapped person to turn on Bluetooth.
[0019] By adopting the above technical solution and integrating a voice module, the evacuation indicator light can interact with trapped personnel in a more intelligent way in emergency situations. The voice module can issue an initial voice prompt to directly inform trapped personnel of the actions they should take, such as pressing a button or turning on Bluetooth. This can reduce the hesitation and confusion of trapped personnel in emergency situations and enable them to take the correct actions quickly.
[0020] Preferably, when the evacuation indicator controller receives a fire alarm signal sent by the fire alarm system, and the evacuation indicator light receives the distress call information from the distress call module and sends it to the evacuation indicator controller, the voice module is also used to issue a second voice prompt, which is used to remind the trapped personnel to wait for rescue in place.
[0021] By adopting the above technical solution, when a fire occurs, after the evacuation instruction controller receives the instruction information, the voice module can send a second voice signal to prompt the trapped personnel to wait for rescue in place, thereby avoiding the trapped personnel from blindly evacuating and entering a more dangerous environment, improving rescue efficiency, and ensuring the safety of the trapped personnel.
[0022] Preferably, when the evacuation indicator controller does not receive a fire alarm signal from the fire alarm system, the distress call module does not generate a distress call signal.
[0023] By adopting the above technical solution, if the distress call module generates distress signals arbitrarily in the absence of a fire, it may cause false alarms of the evacuation indicator lights, thereby causing unnecessary panic and chaos. By ensuring that distress signals are generated only when a fire alarm signal is received, the occurrence of false alarms and misoperations is effectively avoided.
[0024] Preferably, the evacuation indicator controller further includes a self-test module. When the evacuation indicator controller does not receive a fire alarm signal sent by the fire alarm system, the self-test module generates a detection signal and sends the detection signal to the microprocessor. The microprocessor receives the detection signal and determines whether the distress call module can generate a distress call signal.
[0025] By adopting the above technical solution, the self-test module generates a detection signal and sends it to the microprocessor when the evacuation indicator controller does not receive a fire alarm signal, thereby realizing the periodic functional testing of the evacuation indicator system, timely detection and prevention of potential system failures, and ensuring that all components of the evacuation indicator system are in good working condition.
[0026] In summary, this application includes at least the following beneficial technical effects:
[0027] By integrating a distress signal module into the evacuation indicator light, ordinary citizens in dangerous areas can easily trigger a distress signal in emergencies without needing to find other specialized distress equipment, thus improving the timeliness and convenience of calling for help. When the distress signal is triggered, the microprocessor obtains the coded address of the evacuation indicator light and transmits this information through the communication module. The coded address of the evacuation indicator light is unique, enabling firefighters in the fire control room to quickly and accurately locate the person calling for help, providing crucial information for rapid rescue and further improving rescue efficiency.

Detailed Implementation
[0034] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail.
[0035] This application discloses an evacuation instruction system with an emergency call function.
[0036] Example 1
[0037] Reference Figure 1 An evacuation guidance system with emergency call function includes: evacuation indicator lights 100 and evacuation indicator controller 200. In a typical building, multiple evacuation indicator lights and at least one fire control room are installed. One evacuation indicator light controller can be connected to multiple evacuation indicator lights. Specifically, the evacuation indicator light 100 includes a call module 110, a microprocessor 120, and a communication module 130. The microprocessor 120 is connected to both the call module 110 and the communication module 130. The call module 110 generates a call signal, and the microprocessor 120 identifies the call signal from the call module 110. Upon identifying the call signal, the microprocessor 120 obtains the coded address of the evacuation indicator light 100 and sends the coded address to the communication module 130. The communication module 130 transmits the received coded address of the evacuation indicator light 100 and the call signal.
[0038] The evacuation indicator controller 200 is located in the fire control room. The evacuation indicator controller 200 is connected to the communication module 130 and is used to receive the coded address and distress signal of the evacuation indicator 100 sent by the communication module 130, and display the coded address and distress signal so that the firefighters in the fire control room can carry out rescue according to the instruction information.
[0039] More specifically, see Figure 2The distress call module 110 may include a button unit 111 and / or a Bluetooth unit 112. The distress call signal includes a first distress call signal and a second distress call signal. The button unit 111 is located on the evacuation indicator light 100 and is used to generate the first distress call signal when the button unit 111 is pressed. The Bluetooth unit 112 is located inside the evacuation indicator light 100 and is used to generate the second distress call signal when the Bluetooth unit 112 connects with a Bluetooth device carried by a mobile terminal. The button unit 111 can be a capacitive touch button, installed in a conspicuous and easily accessible location on the evacuation indicator light 100, such as below or to the side of the light body. Its internal capacitive sensing circuit can detect capacitance changes caused by human finger touch. After detecting the capacitance change, the distress call module 110 generates the first distress call signal. The microprocessor 120 identifies the first distress call signal generated by the distress call module 110 and, upon identification, obtains the corresponding encoded address of the evacuation indicator light 100. The encoded address and the first distress call signal are then sent to the evacuation indicator controller 200 via the communication module 130. The Bluetooth unit 112 can be a Bluetooth unit 112 that supports Bluetooth Low Energy (BLE) technology and is integrated inside the evacuation indicator light 100. After receiving a fire signal, the Bluetooth unit 112 can continuously broadcast Bluetooth signals. When a nearby mobile terminal (such as a smartphone, tablet, etc.) turns on its Bluetooth function and approaches the evacuation indicator light 100, the Bluetooth unit 112 can pair and connect with the mobile terminal. After detecting that the Bluetooth unit 112 has successfully connected, the distress call module 110 generates a second distress call signal. The microprocessor 120 identifies the second distress call signal generated by the distress call module 110 and obtains the coded address corresponding to the evacuation indicator light 100 after identifying the second distress call signal. The coded address and the second distress call signal are then sent to the evacuation indicator controller 200 through the communication module 130.
[0040] The microprocessor 120 can be a microcontroller chip, installed on a circuit board inside the evacuation indicator 100. The microprocessor 120 stores the coded address of the evacuation indicator 100 and monitors the distress signal transmitted from the distress call module 110 in real time. Upon receiving a distress signal, the microprocessor 120 integrates and packages the distress signal and the coded address to obtain indication information and sends it to the communication module 130.
[0041] The communication module 130 can be a communication circuit. The communication module 130 can be connected to the microprocessor 120 through an interface such as a serial port or SPI. After receiving information containing a distress signal and coded address sent by the microprocessor 120, the communication module 130 sends it to the evacuation indicator controller 200 located in the fire control room according to a predetermined communication protocol.
[0042] The evacuation indicator controller 200 is located in the fire control room. The evacuation indicator controller 200 runs dedicated monitoring software. When it receives a distress signal and coded address sent from the communication module 130 of the evacuation indicator 100, it parses and processes the data, obtains the location corresponding to the coded address of the evacuation indicator 100, and displays the location of the evacuation indicator 100 and the corresponding distress signal status (such as a button being pressed or a connection to a mobile terminal) on a large screen in an intuitive graphical interface (such as the indicator icon flashing or changing color on the building floor plan). This allows firefighters to clearly understand the possible location of trapped people in the building and the status of their distress signals, thus enabling them to carry out rescue operations.
[0043] Furthermore, the evacuation indicator light 100 may also include a display module connected to the microprocessor 120. The microprocessor 120 receives the light-on or light-off indication sent from the evacuation indicator controller 200 via the communication module 130, and controls the display module according to the light-on or light-off indication.
[0044] The implementation principle of an evacuation guidance system with emergency call function in this application embodiment is as follows: After a fire breaks out, people in the building begin to evacuate. At this time, ordinary people trapped inside the building (hereinafter referred to as trapped persons) may not be able to escape in time due to unfamiliarity with the internal routes of the building. Therefore, when a trapped person reaches the vicinity of the evacuation indicator light 100 and needs help, according to the voice prompts issued by the evacuation indicator light, if they choose to press the button unit 111 on the evacuation indicator light 100, based on the principle of capacitive touch, the human body approaches or touches the sensing area of the button unit 111, causing a change in its capacitance value. The capacitance detection circuit inside the button unit 111 keenly captures this change, and after a series of signal conditioning and conversion operations, generates a digital first distress signal (such as a high-level signal) representing the intention to seek help, and quickly transmits it to the microprocessor 120. Alternatively, some trapped persons may use their mobile terminals (such as smartphones) to interact with the evacuation indicator light 100. The Bluetooth unit 112 within the evacuation indicator light 100 continuously broadcasts Bluetooth signals. When a mobile terminal enters its signal coverage area, and the mobile terminal enables its Bluetooth search function and successfully pairs with the Bluetooth unit 112, the Bluetooth unit 112 immediately generates a specific second distress signal (such as a specific digitally encoded signal) and sends it to the microprocessor 120. The generation of these two distress signals provides the microprocessor 120 with crucial information about potentially trapped individuals awaiting rescue, obtained through different means. Upon receiving the distress signal, the microprocessor 120 integrates the acquired distress signal with the determined encoded address to obtain integrated information. The microprocessor 120 then transmits this integrated information to the communication module 130. The communication module 130 further encapsulates the received integrated information into corresponding communication protocol data packets and sends them to the evacuation indicator controller 200 in the fire control room via the fire-fighting dedicated communication bus. After receiving a data packet containing instruction information, the evacuation instruction controller 200 performs unpacking and parsing operations in reverse order to accurately extract the coded address of the evacuation indicator light 100 and the distress signal information. This information is then displayed on the monitoring screen in the fire control room through an intuitive graphical interface or list format, enabling firefighters to launch rescue operations based on the location of the evacuation indicator light 100.
[0045] Example 2
[0046] Reference Figure 3The evacuation indicator controller 200 is connected to the fire alarm system 300 and is used to receive fire alarm signals sent by the fire alarm system 300. Specifically, when the evacuation indicator controller 200 does not receive a fire alarm signal from the fire alarm system 300, the emergency call module 110 does not generate an emergency call signal; when the evacuation indicator controller 200 receives a fire alarm signal from the fire alarm system 300, it receives the fire alarm signal, generates evacuation indicator control information after receiving the fire alarm signal, and sends the fire alarm signal and the generated evacuation indicator control information to the evacuation indicator light 100. The emergency call module 110 generates an emergency call signal when the triggering conditions are met. At this time, the triggering conditions are that the button unit 111 is pressed and / or the Bluetooth unit 112 is connected to the Bluetooth device carried by the mobile terminal. More specifically, the evacuation indicator controller 200 is connected to the fire alarm system 300 via wired (such as RS485 serial cable, Ethernet cable, etc.) or wireless (such as wireless communication circuits in a specific frequency band, in accordance with fire protection industry communication standards) methods to ensure that the two can stably and quickly transmit fire alarm signals.
[0047] Further, see Figure 4 The evacuation indicator light 100 also includes a voice module 140, which is located within the evacuation indicator light 100 and connected to the microprocessor 120. After receiving an alarm signal from the evacuation indicator controller 200, the voice module 140 issues a first voice prompt, which prompts the trapped person to press the button unit 111 and / or to turn on Bluetooth. When the evacuation indicator controller 200 receives a fire alarm signal from the fire alarm system 300, and the evacuation indicator light 100 receives a distress call from the distress call module 110 and sends it to the evacuation indicator controller 200, the voice module 140 issues a second voice prompt, which prompts the trapped person to wait for rescue in place.
[0048] Specifically, the voice module 140 can consist of a voice chip, an audio power amplifier, and a speaker, and is installed inside the evacuation indicator light 100 near the sound outlet. The voice chip stores pre-recorded first voice prompts (such as "Fire has occurred, please press the button on the evacuation indicator light 100 or turn on your mobile phone's Bluetooth to connect to the indicator light to call for help") and second voice prompts (such as "Your distress signal has been sent, rescuers are on their way, please wait where you are and do not move around") and other voice information. When it receives the first or second voice signal sent by the evacuation indicator controller 200, the voice chip decodes the corresponding voice information and drives the speaker to play it through the audio power amplifier.
[0049] The implementation principle of an evacuation guidance system with emergency call function in this application embodiment is as follows: When a fire has not yet occurred, the fire alarm system 300 is in normal monitoring mode and does not send a fire alarm signal to the evacuation guidance controller 200. At this time, the evacuation guidance controller 200 maintains the normal monitoring mode, and the call module 110 (button unit 111 and Bluetooth unit 112) is in a locked state. Even if someone accidentally presses a button or tries to connect via Bluetooth, no call signal will be generated, effectively avoiding the generation of invalid information in non-emergency situations. Once a fire occurs, the fire alarm system 300 generates a fire alarm signal and sends it to the evacuation guidance controller 200. After receiving the fire alarm signal, the evacuation guidance controller 200 sends the fire alarm signal to the evacuation indicator light 100 through the communication module 130. After receiving the fire alarm signal, the voice module 140 of the evacuation indicator light 100 plays a first voice prompt to inform trapped personnel that they can send a distress signal to firefighters by pressing the button unit 111 on the evacuation indicator light 100 or by connecting to the Bluetooth unit 112 and a mobile terminal, guiding trapped personnel to perform self-rescue and call for help. After hearing the first voice prompt, if the trapped person presses button unit 111, button unit 111, based on the principle of capacitive touch, detects the capacitance change caused by human touch, and generates a first distress signal after signal conditioning and conversion by internal circuitry; or if the trapped person chooses to connect to Bluetooth unit 112 using a mobile terminal, Bluetooth unit 112 generates a second distress signal after the mobile terminal enters the signal coverage range of Bluetooth unit 112 and successfully pairs. After the microprocessor 120 recognizes the distress signal, it obtains the encoded address of evacuation indicator 100 and sends the encoded address to evacuation indicator controller 200 through communication module 130. After receiving the coded address, the evacuation indicator controller 200 displays the location and distress signal status corresponding to the coded address of the evacuation indicator 100 on the monitoring interface, so that firefighters can intuitively understand the distribution of the distress locations of trapped people in the building. On the other hand, it sends a receiving signal to the evacuation indicator 100 through the communication module 130 (this receiving signal is used to indicate that the evacuation indicator controller 200 has received the coded address of the evacuation indicator 100). After receiving the receiving signal, the voice module 140 plays a second voice prompt to inform the trapped people that the rescue operation has been initiated, so that they can wait for rescue in place and avoid the danger of blind action. At the same time, it also helps firefighters to more accurately locate the rescue target.
[0050] Example 3
[0051] Reference Figure 5The evacuation indicator light also includes a self-test module 210. When the evacuation indicator controller 200 does not receive a fire alarm signal from the fire alarm system 300, the self-test module 210 generates a detection command that simulates a "fire alarm signal" and sends it to the evacuation indicator light 100. The microprocessor 120 receives the detection command and determines whether the emergency call module 110 can generate an emergency call signal. Specifically, the self-test module 210 is installed on the evacuation indicator controller 200 and connected to the evacuation indicator light 100. It is a separate operating interface or software module that can automatically trigger the generation of a detection command at specific time intervals (such as once a week or once a month). The detection command can be a pulse signal of a specific frequency or a preset digital code signal. This detection command can be recognized by the microprocessor 120 and distinguished from a normal emergency call signal.
[0052] The implementation principle of an evacuation guidance system with emergency call function according to an embodiment of this application is as follows: In non-fire emergency situations (i.e., when the evacuation guidance controller 200 does not receive a fire alarm signal sent by the fire alarm system 300), in order to ensure that the call module 110 of the evacuation guidance system is always in normal working condition, the self-test module 210 generates a detection signal according to a predetermined time period. After receiving the detection signal sent by the self-test module 210, the microprocessor 120 performs functional tests on the call module 110 according to a pre-written detection program. By simulating normal operating conditions (such as simulating button pressing and Bluetooth connection process) and monitoring the response of the call module 110, the microprocessor 120 can determine whether the call module 110 can work normally, thereby discovering potential fault hazards in advance and ensuring that the system can operate reliably in the event of a fire, thus playing its role in emergency call and evacuation guidance.
[0053] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
