Detailed Description
in order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
to facilitate an understanding of embodiments of the present invention, the following detailed description will be further explained with reference to the accompanying drawings.
Fig. 1 is a schematic view of a fire warning system according to an embodiment of the present invention. As shown in fig. 1, the fire alarm system provided in the embodiment of the present invention includes: at least one temperature monitoring warning device 10, a background management device 11 and a mobile terminal 12.
Specifically, at least one temperature monitoring and warning device 10 may be distributed in a network in a place such as an office building, a residential building, a warehouse, etc. for monitoring the hidden condition of fire. In addition, it can be understood that the fire alarm system provided by the embodiment of the invention can also be applied to other fields. Wherein, at least one temperature monitoring and warning device 10 is connected with the background management device 11 through the wireless Mesh network for communication.
It should be noted that each temperature monitoring and warning device 10 is provided with a communication module, each communication module is a node in the wireless Mesh network, and in the wireless Mesh network structure, a node not only can transmit and receive information, but also can serve as a router to forward information to its neighboring nodes. If the nearest node fails or is interfered, the data packet is automatically routed to the standby path for continuous transmission, and the operation of the whole network is not influenced. Therefore, at least one temperature monitoring and warning device 10 is connected and communicated with the background management device 11 through the wireless Mesh network, so that the transmission rate of information can be improved, and the whole fire-fighting warning system can normally operate.
At least one temperature monitoring warning device 10 is distributed at each monitoring point in the monitoring range in a net shape. For example, as shown in fig. 1, the temperature monitoring warning devices 10 are distributed in various rooms of a building, and each room may include a plurality of temperature monitoring warning devices 10 for monitoring the temperature of various monitoring points of the room. Each temperature monitoring warning device 10 is used for monitoring the temperature and sending out a first warning signal when the temperature is greater than a first threshold value; and reporting the monitoring information to the background management device 11, wherein the monitoring information includes position information, temperature information and first warning signal information when the temperature is greater than a first threshold value.
It should be noted that, after each temperature monitoring warning device 10 is installed, the system personnel inputs the location information of the monitoring point to the corresponding temperature monitoring warning device 10 through the background management device 11, for example, "3 rd floor 308 room one on the right". The detection information sent to the background management device 11 by the temperature monitoring and warning device 10 in the following process all carries the position information thereof, so that the background management device 11 can directly know the temperature condition of the specific position thereof according to the temperature information. For example, the detection information may be "308-A1-25 ℃ or" 308-A1-200 ℃ - #1 ", where" 308-A1 "represents position information, A1 represents a preset position arrangement, and" #1 "represents first warning signal information.
Specifically, each temperature monitoring warning device 10 is configured to monitor the temperature of the monitoring point where the temperature monitoring warning device is located, and report the monitored temperature information to the background management device 11 at a certain frequency. When the temperature of the monitoring point is higher than the first threshold, a first warning signal is sent out, and the information of the first warning signal is reported to the background management device 11 at a certain frequency.
The background management device 11 is used for receiving monitoring information reported by at least one temperature monitoring warning device 10, drawing a historical temperature information chart of each monitoring point of the building according to the monitoring information, simultaneously drawing temperature information three-dimensional charts of all monitoring points of the building, controlling the temperature monitoring warning device 10 to send out a second warning signal when the existence of fire hazard is determined according to the historical temperature information chart of each monitoring point and the temperature information three-dimensional charts of all monitoring points, and sending warning information and position information of the monitoring point where a fire source is located to the mobile terminal 12 so that the mobile terminal 12 can process the fire hazard; when it is determined that there is no fire hazard, controlling the temperature monitoring warning device 10 to release the first warning signal; when it is not possible to determine whether there is a fire hazard, a prompt message is sent to the mobile terminal 12.
Specifically, the background management device 11 determines whether there is a fire hazard according to a temperature change curve of a monitoring point where a temperature monitoring warning device that sends out first warning signal information is located, according to a change condition of the temperature of the monitoring point where the temperature monitoring warning device around the temperature monitoring warning device that sends out the first warning signal information is located, and according to change information of the number of the temperature monitoring warning devices that send out the first warning signal information; when the existence of the fire hazard is confirmed, the level of the fire hazard is further judged.
Specifically, the fire hazard is classified into a first-level fire hazard, a second-level fire hazard or a third-level fire hazard; when the existence of the first-level fire hazard is confirmed, controlling all the temperature monitoring warning devices to send out second warning signals; when the existence of secondary fire hidden danger is confirmed, controlling a temperature monitoring warning device which sends out first warning signal information and a temperature monitoring warning device adjacent to the temperature monitoring warning device to send out a second warning signal; when the existence of three-level fire hazard is confirmed, the temperature monitoring warning device which sends out the first warning signal information is controlled to send out a second warning signal, and meanwhile, warning information and position information of a monitoring point where a fire source is located are sent out to the mobile terminal, so that the mobile terminal can process the fire hazard.
In one example, when the number of temperature monitoring warning devices 10 that issue the first warning signal is less than N, which may be 1/5 for example, the number of temperature monitoring warning devices 10 in a house; when the number of houses with fire hazards is larger than M and smaller than S, the houses are second-level fire hazards, for example, M is larger than or equal to 1, and S is larger than or equal to 3; and when the number of the houses with the fire hazard is greater than S, the houses are the first-level fire hazard. Wherein, the first-level fire hazard indicates that the fire condition is the most serious, and so on. In addition, the evaluation standard of the fire hazard can be set according to specific conditions.
The fire-fighting warning system provided by the invention can be used in places with gathered population or articles, such as office buildings, resident residences, warehouses and the like. Compared with the existing fire-fighting warning system adopting a smoke alarm, the fire-fighting warning system provided by the invention can be used for more intelligently preventing and treating fire.
In one example, the background management device receives monitoring information reported by at least one temperature monitoring warning device, summarizes historical data, updates temperature data and position information constantly, judges whether fire hazard exists according to the monitoring information, controls the temperature monitoring warning device to send out a second warning signal when the temperature is found to rise rapidly and abnormal temperature is higher and higher, and instructs the temperature monitoring device to display the fire hazard signal when the fire hazard exists; and further sends out fire hazard warning to mobile terminals such as mobile phones and the like to inform fire source position information. The invention can reduce false alarm, has quick response time to fire monitoring, quickly determines the fire source and reduces personal and property loss.
in one example, in an office building, the temperature monitoring warning devices may be distributed at different monitoring points of the building, such as being networked at various corners of the office building. Firstly, when a certain monitoring point of an office building is on fire, a temperature monitoring warning device of the monitoring point sends out a first warning signal when monitoring that the temperature is greater than a set first threshold value. The first warning signal can also be understood here as a self-warning signal. And secondly, the temperature monitoring and warning device of the monitoring point reports the first warning signal to a background management device, wherein the background management device can also be a mobile phone terminal or a computer terminal and other equipment directly, the holder of the background management device or the background management device judges according to the self-warning signal and the temperature information of the corresponding monitoring point and the surrounding monitoring points, and when the existence of the fire hazard is determined, all the temperature monitoring and warning devices of the office building are controlled to send out second warning signals. Here, the second warning signal can also be understood as a system warning signal.
In particular, the first warning signal and the second warning signal may include LED lights, ring tones, and the like. Wherein the first warning signal and the second warning signal may be set to have different colors of lights to distinguish the self-warning signal from the system warning signal. In addition, the first warning signal and the second warning signal indicator light can be indicated in the form of dynamic flashing, light and shade change or color change and the like.
It should be noted that the first threshold temperature may be specifically set according to the material of the monitoring point, for example, for some flammable materials, a lower first threshold temperature may be set. In addition, the first threshold temperature may be adjusted as needed.
It can be understood that, when the background management device 11 determines that a fire hazard exists, it may also send related information to the fire department, so as to better deal with the disaster and reduce personal and property losses.
Fig. 2 is a schematic structural diagram of a temperature monitoring warning device 10 according to an embodiment of the present invention. As shown in fig. 2, each temperature monitoring warning device 10 includes: the temperature monitoring module 101, the control module 102, the LED warning display module 103 and the first communication module 104; wherein the content of the first and second substances,
And the temperature monitoring module 101 is used for monitoring the temperature of a monitoring point where the temperature monitoring module is located.
The control module 102 is used for controlling the warning module 103 to send out a first warning signal when the monitored temperature is greater than a first threshold value;
specifically, the control module 102 is further configured to instruct the LED warning display module 103 to send a second warning signal or instruct the LED warning display module 103 to release the first warning signal according to the control information sent by the background management device 11.
And the LED warning display module 103 is used for sending out a first warning signal when the temperature is higher than the first threshold value, and/or sending out a second warning signal after the background management device 11 determines that a fire hazard exists, and providing illumination to indicate the position of the fire source.
Specifically, the LED warning display module 103 may be provided with a battery, so that in case of power failure due to fire, the LED warning display module 103 may also emit a warning signal and provide illumination light.
The first communication module 104 is configured to send the monitoring information to the background management apparatus 11.
in one example, the LED warning display module 103 may include two different colored LED lights, for example: yellow and red lights. When the warning module sends out the first warning signal, the yellow lamp can be conducted through the internal control circuit, and yellow light warning is sent out. When the warning module sends out the second warning signal, the red light can be conducted through the internal control circuit, and the red light warning is sent out. Meanwhile, a white lamp can be emitted to provide illumination and prompt the position of the fire source.
In another example, the LED warning display module 103 may further include a ring warning circuit. When it sends out the first warning signal or the second warning signal, it can accompany the corresponding ring warning to send out the warning. The frequencies of the ring tones corresponding to the first warning signal and the second warning signal may be set to be different.
It is understood that the color of the LED lamp is not limited to yellow, red or white, and it is within the scope of the present invention to change the color and the lighting manner of the LED lamp for the alarm signal or the illumination signal.
Specifically, the temperature monitoring warning device 10 may be in the form of a probe, the probe tip of which is the temperature monitoring module 101, which may be a temperature sensor. The other modules are arranged in sequence. Meanwhile, the functions of the device may not be limited to the modules listed in the present invention, and devices achieving the same effect may be replaced by other modules, which are within the scope of the embodiments of the present invention.
Fig. 3 is a schematic structural diagram of the background management apparatus 11 according to the embodiment of the present invention. As shown in fig. 3, the background management apparatus 11 includes: a second communication module 111, a hidden danger determining module 112 and a display module 113; wherein the content of the first and second substances,
The second communication module 111 is configured to receive monitoring information sent by the temperature monitoring and warning device 10; and/or is used for sending control information for sending out a second warning signal to the temperature monitoring warning device 10 when the existence of the fire hazard is determined, and sending warning information and position information of a monitoring point where the fire source is located to the mobile terminal 12 so that the mobile terminal 12 can process the fire hazard; and/or control information for transmitting the first warning signal to the temperature monitoring warning device 10 when it is determined that there is no fire hazard; and/or is used for sending prompt information to the mobile terminal 12 when whether the fire hazard exists cannot be determined, so that the mobile terminal 12 can check and determine whether the fire exists in time and take precaution work well.
And the display module 112 is used for drawing historical temperature information charts of all monitoring points of the building according to the monitoring information and simultaneously drawing temperature information stereo charts of all monitoring points of the building.
the hidden danger determining module 113 is configured to determine status information of at least one temperature monitoring warning device 10 according to the historical temperature information graphs of each monitoring point and the temperature information stereo graphs of all monitoring points, where the status information includes: determining that a fire hazard exists, failing to determine whether a fire hazard exists, or determining that a fire hazard does not exist.
specifically, as described in fig. 1, when it is determined that there is a fire hazard, the fire hazard may be further classified into a first-level fire hazard, a second-level fire hazard, or a third-level fire hazard, and a classification standard of the related fire hazards, which may be referred to as a record in fig. 1 and will not be repeated herein.
in one example, when the difference between the temperature of the monitoring point where the temperature monitoring warning device 10 which sends the first warning signal information is located and the temperature of the monitoring point where the temperature monitoring warning device 10 around the temperature monitoring warning device is located is not large, further, when the temperature of the surrounding temperature monitoring warning device 10 does not change within a certain time, it is determined that there is no fire hazard, and meanwhile, related personnel can be further notified to check before, and the first warning signal is released.
in another example, when the temperature monitoring and warning device 10 at the more distributed monitoring points simultaneously sends out the first warning signal information, but the temperature information monitored by the surrounding temperature monitoring and warning device 10 does not change significantly, after the existence of the fire hazard is determined, the relevant personnel can be notified to check before and then give a corresponding response.
specifically, in a possible embodiment of the present invention, the background management device 11 may further determine whether a fire hazard exists according to other criteria. For example, the conclusion whether the monitoring point where the temperature monitoring and warning device 10 reporting the first warning signal is located has the fire hazard can be obtained through differentiation judgment according to the difference between the temperature of the monitoring point corresponding to the temperature monitoring and warning device 10 reporting the first warning signal and the temperature of the surrounding monitoring points.
Specifically, in another possible embodiment of the present invention, the background management device 11 may also disregard the first warning signal information of the at least one temperature warning device 10, and directly make a decision according to all temperature information reported by the at least one temperature warning device 10. For example, the number of the temperature monitoring and warning devices 10 with the temperature exceeding the first threshold value is set as the threshold value, or the monitoring point where the temperature monitoring and warning device 10 with the temperature exceeding the first threshold value is located is set as the threshold value, so as to determine whether the fire hazard exists. For another example, whether fire hazard exists is judged according to temperature differentiation information reported by at least one temperature monitoring and warning device.
The process of determining whether there is a fire hazard by the background management apparatus 11 may be set by a program and automatically executed. Or the holder of the background management device 11 may make a judgment by itself according to the related information and send a corresponding instruction. When the fire hazard cannot be determined, related personnel can be prompted to go to the site to check so as to make further judgment and prevent personal safety and property loss.
It should be noted that, the background management device receives the temperature information and the warning signal information of each monitoring point of the system, so as to better monitor the fire. For example, the system may control to turn off the false alarm signal when the temperature at a certain point may temporarily exceed the first threshold temperature, but is not a fire and false alarm. In addition, the temperature monitoring and warning device is adopted, compared with the traditional smoke warning device, the fire monitoring device is more sensitive to fire monitoring, and the fire source is easily determined according to the temperature information reported by the temperature monitoring and warning device of each monitoring point.
Fig. 4 is a schematic diagram of a specific application of the fire warning system according to the embodiment of the present invention. As shown in fig. 4, the house 1 may include 6 temperature monitoring warning devices, such as a1-a6, and other temperature monitoring warning devices, such as a7-a9 shown in fig. 4, may be included in the house adjacent to the house 1.
When a fire is in the lower part of the temperature monitoring warning device indicated by a1 and the monitored temperature is greater than a first threshold value, a1 sends out a first warning signal, such as a yellow light alarm, and a1 reports the first warning signal information to the background management device. The background management device receives the first warning signal information of A1 and analyzes the temperature information reported by A2-A9 and the like around the background management device.
for example, a2, a4 and a5 around a1 will gradually report first warning signal information, when the number of temperature monitoring warning devices sending out the first warning information is greater than 3, the background management device will determine that a fire hazard occurs in the house 1, will control all the temperature monitoring warning devices a1-a6 in the house 1 to send out second warning signals, and at the same time, will also control the temperature monitoring warning devices a7-a9 and the like of the surrounding houses to also send out second warning signals. In addition, when the spreading speed of the fire hazard is fast, for example, the number of houses with the fire hazard exceeds 1/5 of the number of houses in the building, the background management device controls all the temperature monitoring and warning devices in the whole building to send out second warning signals, and prompts relevant personnel to take corresponding measures.
the temperature monitoring warning device and the fire fighting warning system provided by the embodiment of the invention realize a double-layer warning mechanism and system monitoring, can monitor the monitoring points where a single temperature monitoring warning device is located, and send out self-warning signals when the temperature is abnormal, and control all the temperature monitoring warning devices to send out system warning signals when the fire hazard is determined to exist by reporting the monitoring information of all the monitoring points to the background management device. The fire monitoring system can reduce false alarm, has quick response time to fire monitoring, and reduces personal and property loss. Meanwhile, the hidden danger fire source can be determined more quickly according to the temperature monitoring result and the source of the warning signal. The time for fire extinguishing and escaping is strived for the fire fighters.
