Technical Field
[0001] The utility model relates to the technical field of fire detection and rescue, and in particular to a detection device for fire monitoring and rescue escape assistance. Background Art
[0002] With the rapid development of IoT technology, the monitoring and management requirements for modern building fire prevention are increasing, and the requirements for fire detection and rescue technology are also constantly increasing. Currently, traditional fire monitoring equipment mostly uses a single temperature detection module or smoke detection module for detection. These detection types are limited to a single fire feature and are unable to provide graded reports based on the specific fire situation. Furthermore, existing fire monitoring equipment can only detect environmental parameters such as smoke and temperature. It cannot detect the presence of people in the monitored area and cannot provide location information for trapped people for fire rescue. This leads to delayed fire rescue and the lack of a corresponding on-site reporting system for escape guidance. Utility Model Content

[0023] See also Figure 1 A detection device for fire monitoring and rescue escape assistance includes: a processing module 400 and multiple acquisition components, the multiple acquisition components are distributed in different areas to be detected, the acquisition components include a smoke detection module 100, a temperature detection module 200, and a microwave radar detector 300, the smoke detection module 100 is used to detect smoke concentration and generate a first signal, the temperature detection module 200 is used to detect temperature and generate a second signal, and the microwave radar detector 300 is used to detect human activity and generate a third signal; the processing module 400 is electrically connected to the multiple acquisition components, the processing module 400 is electrically connected to an ad hoc network module 500 and a voice module 600, and the processing module 400 is connected to a remote management platform 800 via a communication module 700; wherein, based on the first and second signals generated in different areas, the processing module 400 performs signal threshold analysis and generates a fire level for the corresponding area, and based on the third signal generated in different areas, the processing module 400 performs human presence analysis, and the communication module 700 transmits data to the remote management platform 800, which broadcasts fire reports and provides escape guidance via the voice module 600.
[0024] When the fire monitoring and rescue escape auxiliary detection device of the above structure is used, the smoke detection module 100 detects the concentration change in the area and produces a first signal, the temperature detection module 200 detects the temperature change in the area and produces a second signal, and the processing module 400 performs threshold analysis after receiving the first signal and the second signal. When the first signal or the second signal exceeds the preset threshold, the processing module 400 determines that the fire level in the area is a normal alarm, the voice module 600 broadcasts, and the processing module 400 uses the communication module 700 to transmit the data to the remote management platform 800; when both the first signal and the second signal exceed the preset threshold, the processing module 400 determines that the fire level in the area is an emergency alarm, the voice module 600 broadcasts, and the processing module 400 uses the communication module 700 to transmit the data to the remote management platform 800. The remote management platform 800 issues voice commands to the voice modules 600 in each area, thereby realizing voice broadcast of the entire fire scene. When a first signal or a second signal is present in a certain area, the microwave radar detector 300 is activated to detect a third signal. The processing module 400 transmits data to the remote management platform 800 via the communication module 700. Simultaneously, the processing module 400 sends linkage instructions to the acquisition components in other areas via the ad hoc network module 500 for signal acquisition. The remote management platform 800 combines the data uploaded by the processing module 400 to analyze the fire situation and provide escape guidance, generating escape guidance instructions. These escape guidance instructions are then sent to the voice module 600 via the communication module 700 for fire reporting and escape guidance. This structure enables comprehensive, accurate, and rapid fire detection and provides relevant rescue and escape information, facilitating timely rescue efforts by rescue personnel and facilitating the escape of on-site personnel.
[0025] It can be understood that the collection components of each area upload data through the corresponding communication module 700, or the collection components of each area can also forward the data to the processing module 400 of other areas through the networking module 500 and then upload the data through the communication module 700 of other areas, thereby completing the alarm signal collection and data transmission of each area, and executing instructions such as fire broadcast and escape guidance.
[0026] It is understandable that the processing module 400 can also further determine the development trend of the fire by analyzing the time series data of smoke concentration and temperature changes. When the smoke concentration rises rapidly, accompanied by a sharp increase in temperature, it is a signal that strongly indicates the occurrence of a fire. At this time, the fire level can also be determined as an emergency alarm. Among them, the microwave radar detector 300 is a non-contact sensor 110 based on the principle of Doppler effect, which is used to detect the presence of people in the area. Specifically, the microwave radar detector 300 includes a transmitter and a receiver. The transmitter continuously emits a microwave signal of a certain frequency. When the microwave signal encounters a moving object and is reflected, a Doppler effect will occur. That is, the frequency of the reflected microwave signal and the transmitted wave signal will have a slight offset, thereby determining the presence of people in the area.
[0027] Furthermore, the remote management platform 800 includes a display module, which has color blocks corresponding to the areas to be detected. Based on the first signal and the second signal generated by the area, the remote management platform 800 controls the color blocks to change to red, yellow or green according to the fire level. Specifically, when the collection component of a certain area generates the first signal or the second signal, the processing module 400 determines that the fire level of the area is a normal alarm, and the color block corresponding to the area is displayed yellow. When the collection component of a certain area generates the first signal and the second signal, the processing module 400 determines that the fire level of the area is an emergency alarm, and the color block corresponding to the area is displayed red. If the collection component of a certain area does not generate the first signal or the second signal, the processing module 400 determines that there is no fire in the area, and the color block corresponding to the area is displayed green. Through the above structure, it is convenient for people to know the fire situation in different areas, so that they can use the voice module 600 to broadcast the fire in time.
[0028] It can be understood that the corresponding area generates a third signal, and the corresponding color block is displayed as a blue circle. The communication module 700 of the different area transmits data to the remote management platform 800. The remote management platform 800 plans and analyzes the escape route based on the area, and the planned route is displayed in green, so that it is convenient for the fire scene personnel to use the voice module 600 to perform escape guidance.
[0029] See also Figure 1Furthermore, the smoke detection module 100 includes a sensor 110 and a first signal processor 120 that are electrically connected to each other. The first signal processor 120 can preset a first threshold value of smoke concentration. The first signal processor 120 is electrically connected to the processing module 400. Specifically, when smoke enters the sensor 110, the smoke particles scatter light, causing the intensity of the light received by the sensor 110 to change. When the smoke concentration is greater than the first threshold value, the sensor 110 converts the optical signal into an electrical signal. The first signal processor 120 receives the electrical signal and performs logical analysis, and finally transmits the processed data directly to the processing module 400. It is understandable that the smoke detection module 100 can select a photoelectric smoke detector, an ionization smoke detector, a compound smoke detector, and an aspirating smoke detector as needed, which will not be described in detail here.
[0030] See also Figure 1 Furthermore, the temperature detection module 200 includes a sensitive element 210 and a second signal processor 220 electrically connected to each other. The second signal processor 220 can preset a second temperature threshold, and the second signal processor 220 is electrically connected to the processing module 400. Specifically, when a fire occurs in a certain area, the ambient temperature will rise rapidly, and when the temperature detected by the sensitive element 210 exceeds the set second threshold, the sensitive element 210 converts the temperature change into an electrical signal, and the second processing module 400 receives the electrical signal and performs logical analysis, and finally transmits the processed data directly to the processing module 400. It can be understood that the temperature detection module 200 can select a fixed temperature temperature detector, a differential temperature temperature detector or a differential fixed temperature temperature detector as needed, which will not be described in detail here. Among them, a differential fixed temperature temperature detector is used, which combines the functions of fixed temperature and differential temperature. It can generate an alarm signal when the temperature reaches a certain value, and can also generate an alarm signal when the temperature rises too fast, thereby more effectively detecting the temperature changes in the area.
[0031] Furthermore, the sensitive element 210 is a thermistor or a thermocouple, so as to be able to convert temperature changes into electrical signals.
[0032] See also Figure 1 Furthermore, processing module 400 is electrically connected to a storage module 410 for storing data, thereby storing thresholds for various fire characteristics and facilitating the pre-entry of voice information. It is understood that the storage module can utilize a storage medium such as an SD card or TF card as needed, which will not be described in detail here.
[0033] Furthermore, the ad hoc network module 500 is a Bluetooth module, ZigBee module, WiFi module, or LoRa module. Specifically, the ad hoc network module 500 enables data intercommunication between multiple acquisition components, thereby enabling interconnected analysis of each region, facilitating the processing module 400's networked analysis of fire severity and escape routes in each region. The network model established using the ad hoc network module not only enables data forwarding between acquisition components in different regions, but also offers excellent interference resistance, ensuring stable and reliable network communication in complex environments and facilitating better collaboration between devices.
[0034] Furthermore, the processing module 400 is a single chip microcomputer. Specifically, the processing module 400 is used to analyze and process the smoke concentration, temperature changes, personnel information, etc. in the area and perform signal conversion, including network operation processing, communication protocol conversion, and data transmission and reception.
[0035] Furthermore, the communication module 700 is one or any combination of a 5G module, a 4G module, a LoRa module, a NB-IoT module, a Wi-Fi module, or an Ethernet module. Specifically, the communication module 700 can directly use one of the above modules, or a combination of multiple modules to achieve a connection between the processing module 400 and the remote management platform 800. It is understood that the communication module 700 can be connected to the remote management platform 800 via a wired or wireless connection, which is not limited here.
[0036] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0037] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
