In the present embodiment, in order to monitor a fire disaster, a fire monitoring system 8 as shown in fig. 1 is used to remotely monitor a fire disaster in a monitored place, and the fire monitoring system 8 includes a plurality of smoke detectors 1 installed on the faces of a building at the monitored place, and a remote server 82 communicating with the smoke detectors 1 through a communication network including a base station 81. Among them, the remote server 82 constitutes the disaster monitoring apparatus of the present invention.

The battery module 4 provides electric energy for normal operation of other functional modules, namely the smoke detector 1 in the embodiment is an independent smoke detector powered by a battery; the control module 2 comprises a processor 20 and a memory 21. The smoke detection module 3 constitutes a disaster monitoring module in the embodiment, and is used for monitoring whether the smoke concentration around the smoke detector 1 exceeds a threshold value, namely, monitoring the fire phenomenon of smoke to judge whether the fire occurs; the 2G communication module 5 adopts a mobile communication module, which is specifically a 2G communication module in this embodiment; the WIFI probe module 7 constitutes a mobile terminal detection module in this embodiment, and is used to monitor a field disaster different from a fire, that is, to detect information of the mobile terminal in a monitored location, including but not limited to working state information and a WIFI MAC address.

As shown in fig. 3, the steps of monitoring the monitored location using the smoke detector 1 include an acquisition step S11, a transmission step S12, a reception step S13, and a response step S14, that is, when the processor 20 executes the computer program stored in the memory 21, the aforementioned acquisition step S11, transmission step S12, reception step S13, and response step S14, that is, the power management method thereof, can be implemented.

An acquiring step S11, when the fire monitoring module detects the fire condition, the mobile terminal detecting module is activated to acquire the information related to the mobile terminal within the detectable range thereof as the detection information.

Smog monitor 3 exports smog monitoring signal to control module 2, when the smog that the conflagration produced is monitored by smog monitoring module 3 to the time, control module 2 is obtaining behind smog monitoring information sign smog concentration and reaching the preset concentration threshold value, it monitors the conflagration expression to characterize it, export start control information to WIFI probe module 7, WIFI probe module 7 starts and scans the equipment of smoke detector 1 within a certain range around, acquire WIFI detection information, this WIFI detection information is including being in the WIFI MAC address of the equipment that wireless network opened the form and the distance range between these equipment and smoke detector 1, for example, intelligent TV, electric rice cooker, washing machine, the WIFI MAC address and the cell-phone of non-mobile terminal such as air conditioner, intelligent bracelet, the WIFI MAC address of mobile terminal such as panel computer.

In the present embodiment, the detection information includes detection time information, position information or position-related information of the smoke detector 1, a device MAC address, and a distance range between the device and the smoke detector 1, which is roughly determined based on the detected signal strength of the device or other methods. Wherein the detection time information comprises the time when the smoke concentration reaches the threshold value and/or the time for acquiring the WIFI detection information, and one of the time representation detection time information is adopted because the two are close to each other. The location-related information refers to a mark that can be used to find specific information of the installation location of the speech detector 1, such as a product number or an installation number of the smoke detector, and according to the location-related information, a corresponding relationship between the product number or the installation number and specific installation address information can be found from an installation database to obtain the installation location information of the smoke detector, where the installation location information generally includes an address of an installation building, an installation floor, and a location in a floor access map.

The transmission step S12 is to start the wireless communication module 5 and transmit the probe information acquired in the acquisition step S11.

After acquiring the probe information, the control module 2 outputs communication start control information to the wireless communication module 5 so that the wireless communication module 5 transmits the probe information to the remote server 82 via the nearby base station 81.

As shown in fig. 4, the remote server 82 includes a control module 91 and a communication module 94, wherein the control module 91 includes a processor 93 and a memory 92, and processes the detection information sent by the smoke detector 1, that is, the processor 93 executes a computer program stored in the memory 92, so as to implement the receiving step S21, the identifying step S22, the generating step S23, and the sending step S24 shown in fig. 5.

The receiving step S21 receives detection information transmitted by the fire detector 1 installed at the monitored site.

The remote server 82 receives detection information transmitted from a plurality of fire detectors 1 installed at a monitored site through a communication network including the base station 81.

As shown in fig. 1, four smoke detectors 1 with numbers of 1-1, 1-2, 1-3 and 1-4 are installed at predetermined positions on a ceiling of a monitored place of a certain building, and due to the difference in detection range of a WIFI probe module 7, the existence of a shelter and the distance between a device in a wireless network on state and the WIFI probe module 7, each smoke detector 1 can only detect sub-devices inside the place to acquire the WIFI MAC address thereof, for example, the WIFI probe module 7 on the smoke detector 1 with the number of 1-1 acquires the MAC addresses of a first mobile phone, a first bracelet, a first air conditioner and a first television, the WIFI probe module 7 on the smoke detector 1 with the number of 1-2 acquires the MAC addresses of the first bracelet, the first mobile phone and the first television, and the WIFI probe module 7 on the smoke detector 1 with the number of 1-3 acquires the MAC addresses of a second mobile phone and a first tablet computer, WIFI probe module 7 on smoke detector 1 with the serial number of 1-4 has obtained the MAC address of first washing machine, and first cell-phone, first bracelet and first TV are detected by WIFI probe module 7 on two smoke detector 1 simultaneously promptly.

The detection information received by the remote server 82 is composed of four sets of detection information acquired by the four smoke detectors 1. The probe information at this time is transmitted to the remote server 82 through the communication line (r) and the communication line (c) shown in fig. 1.

And an identifying step S22, based on the received detection information, judging whether the target mobile terminal exists around the current detector, if so, predicting or determining that people exist in the surrounding space of the current detector.

In this embodiment, the mobile terminal is configured as a device whose MAC address is stored in an address base; the target mobile terminal is configured as a mobile terminal with a wireless network or Bluetooth in an on state; judging whether the current WIFI MAC address exists in a pre-stored address library or not, and if so, determining that the equipment is a mobile terminal; when a target mobile terminal is detected around the current fire detector, trapped people in the surrounding space are predicted or determined according to a certain probability to generate disaster information.

The remote server obtains the WIFI MAC address after receiving the detection information, compares the WIFI MAC address with the mobile terminal MAC address stored in a pre-stored address base, namely compares the WIFI MAC address with a reference MAC address to judge whether a mobile terminal in a wireless network opening state exists around the smoke detector 1 so as to represent whether trapped people exist around the smoke detector, and the mobile terminal MAC address stored in the database is input in advance or output to the remote server along with the detection information. For the MAC address of the mobile terminal stored in the database, specifically, when installing the smoke detector 1, the operator may input the MAC address of the mobile terminal currently held by the person working in the space around the smoke detector or working in the area frequently, for the input of the MAC address, register the APP and input the MAC address into the database under the condition of obtaining the authorization, and periodically input the MAC address of the newly added mobile terminal through the APP, and remove the unused MAC address through the APP; for the newly added MAC address, the wireless communication module 5 can be started to receive the manually input newly added MAC address by triggering an input key arranged on the smoke detector, the newly added MAC address is automatically bound with the position of the smoke detector, the triggering input key can be a newly arranged key or can trigger the starting of the wireless communication module 5 based on continuously pressing a self-checking silencing switch twice to receive externally input information, and the smoke detector periodically transmits the received newly added MAC address and the eliminated MAC address to the numerical control library; and when the smoke is detected, the MAC address which is not transmitted out is synchronously sent out with the detection information.

Because part of the MAC address is bound with at least one smoke detector 1 in the pre-stored address base, namely, two sub-address bases are stored in the pre-stored address base, namely, an associated address base associated with the current fire detector and a non-associated address base not associated with the current fire detector.

The remote server 82 compares the detected WIFI MAC address with WIFI MAC addresses in a library of pre-stored addresses, and if the detected WIFI MAC address is stored in the database and associated with the smoke detector, presumably the presence of trapped personnel. Of course, for the existence of the matched WIFI MAC address in the database, although not associated with the current smoke detector, it may be considered that the trapped person exists with a high probability, and the reliability level is higher than the WIFI MAC address related to the current smoke detector. Namely, the probability that people exist when the current WIFI MAC address is stored in the non-associated address base is greater than the probability that people exist when the current WIFI MAC address is stored in the associated address base.

For the distance range information between the equipment and the current smoke detector in the detection information, the remote server can define the position area of the equipment based on the distance range obtained by detecting the same equipment by more than two fire detectors within a preset time difference, the specific method for measuring the distance range is to calculate based on the signal intensity, specifically, the method can be obtained by calibrating the relationship between the signal and the distance of each device in the monitored place in advance and searching a list based on the signal intensity, wherein each signal intensity corresponds to an annular area, for example, as shown in the schematic diagram of fig. 6, the smoke detector 1 numbered 1-1 is positioned at a distance from a certain device determined as an annular area surrounding one circle, i.e. an annular region surrounded by two imaginary circles centered on the installation position of the smoke detector 1, numbered 1-1 in the figure. For example, as shown in the schematic diagram of fig. 6, the WIFI MAC addresses of the first mobile phone and the first bracelet are acquired by the smoke detector 1 labeled as 1-1 and 1-2, and then the position areas of the first mobile phone and the first bracelet can be defined according to the distance range between the first mobile phone and the smoke detector and the device, where the position range is the dashed line area 02; for the first tablet computer, a circular ring-shaped area 03 of a curve of a range of the first tablet computer can be drawn only by taking the position of the smoke detector with the number of 1-3 detected as the center of a circle, namely, the part of the circular ring-shaped area exceeding the boundary of a wall body and the like of a monitored place is not calculated; in the specific positioning process, the position area of the two circular ring-shaped areas or the overlapping area of the multiple circular ring-shaped areas can be defined based on the overlapping area of the two circular ring-shaped areas or the overlapping area of the multiple circular ring-shaped areas, so that the position of the device is roughly positioned, and if the device is a mobile terminal device, the position of the device can be regarded as the position of the trapped person.

A generating step S23, which is to generate at least first disaster information, second disaster information, and control information based on the received detection information, where the first disaster information has fewer details than the second disaster information, the disaster information includes whether there is a person in the surrounding space of the current detector, and the control information is used to control a monitor in the monitored location to perform a power management operation.

The disaster information sent by the remote server to different communication devices can be the same or different, and under the condition that the sent disaster information is different, the disaster information with different details is sent according to the working type of a communication device user and the role of the communication device user in rescue and fire extinguishing, for example, the remote server generates first disaster information, second disaster information and third disaster information based on the received detection information, wherein the first disaster information has less details than the second disaster information, the second disaster information has less details than the third disaster information, the third disaster information is sent to the fire command scheduling platform, the second disaster information is sent to the handheld transfer device of the fire fighter, and the first disaster information is sent to the property management platform, so that the remote server can make decisions according to the respective working requirements and time shortage.

The control information is generated for controlling the power supply of a target fire monitor in the monitored place after the target mobile terminal is identified in the monitored place. In this embodiment, the control information is used to turn off the wireless communication module 5 and the WIFI detection module on the target monitor that receive the control information, and turn on the alarm module 23 on the target monitor to perform alarm; wherein, warning module utilizes the speaker for carrying out the emergence module of sound production, or carries out luminous light emitting module, like flash of light LED to carry out the sound production police and/or give out light to warn, can utilize comparatively sharp-pointed and the stronger frequency of penetrability to carry out the sound production to taking place the warning, can warn for the interval predetermined duration's same sound of repetition.

In the control information, the warning mode of the warning module 23 can select different warning modes according to different situations, so as to convey different information to the rescuers.

(1) If the WIFI MAC address of the target mobile terminal is stored in the associated address base, the control information is used for controlling a warning module of the target monitor to warn in a first mode;

(2) if the WIFI MAC address of the target mobile terminal is stored in the non-associated address base, the control information is used for controlling a warning module of the target monitor to warn in a second mode;

(3) and if the target mobile terminal comprises a mobile terminal with a WIFI MAC address stored in the unassociated address base and a mobile terminal with a WIFI MAC address stored in the unassociated address base, the control information is used for controlling the warning module of the target monitor to warn in a third mode. For example, the first warning mode is a repeating "dropping" sound at predetermined time intervals, the second warning mode is a repeating "dropping" sound at predetermined time intervals, and the third warning mode is a repeating "dropping" sound at predetermined time intervals.

A sending step S24, sending disaster information corresponding to the detail degree to the devices with different requirements, and sending the control information generated in the previous step to at least one target monitor in the monitored site. Specifically, the first disaster information is sent to the first device, and at least one of the first disaster information and the second disaster information is sent to the second device.

The control information is transmitted to the target monitor, in this embodiment the smoke detector 1 numbered 1-2, according to the communication line (c) and the communication line (c). For selecting the smoke detector 1 numbered 1-2 as the target monitor, the selection can be based on one of the following rules:

(1) the target detector is a disaster monitor with a target mobile terminal in a detectable range, for example, the smoke detector 1 numbered 1-1, 1-2 or 1-3 in this embodiment, and one, two or three of the smoke detectors may be selected as the target monitor.

(2) The target detector is a disaster monitor with the highest residual battery in the monitored place 01.

(3) The target detector is a disaster monitor with the residual battery quantity in the monitored place 01 larger than a preset threshold value.

(4) The target monitor is a smoke detector closest to the entrance of the monitored site 01.

(5) The target monitor is one of a group of disaster monitors that are closer to the center position 04 of the position range in the horizontal direction; the 'one group of disaster monitors' is composed of disaster monitors which are installed in a monitored place and have a difference between a distance between the disaster monitors and the central position 04 and a standard distance within a preset range, the standard distance is a distance between the disaster monitor closest to the central position and the central position 04, and in the embodiment, the 'one group of disaster monitors' comprises smoke detectors with numbers of 1-1 and 1-2. Specifically, control information is sent to one disaster monitor with the highest residual battery amount in the selected group of disaster monitors; or, the control information is transmitted to at least the target monitor whose battery remaining amount is located at the first two digits.

As for the above-mentioned location range, in the above-mentioned identification step, based on the signal strength information of the target mobile terminal and the location information of the current disaster monitor in the monitored location, the location range of the target mobile terminal in the monitored location is obtained, the location range corresponding to the center location is the integrated location range in which all the target mobile terminals in the monitored location are identified, the specific calculation procedure for the coordinates of the location center is to establish an XOY coordinate system along the boundary with the boundary point of the monitored location 01 as the origin, first obtain the coordinates (X1, Y2) of the center location of the area 02 and the coordinates (X2, Y2) of the center location of the area 03, and use the coordinates ((X1+ X2)/2, (Y1+ Y2)/2) as the coordinates of the center location 04 of the location range in the monitored location, of course, the center coordinates of the two areas may be weighted, how much weight is added to the smoke detected by several smoke detectors 1, for example ((2X 1+ X2)/3, (2X Y1+ Y2)/3) in the graph shown in fig. 6.

In the above selection rule, if more than two smoke detectors are selected as the target monitor, it is needless to say that more than one disaster monitor can be left to continue monitoring the monitored site 01 until their batteries are exhausted or burned out.

For more than two target monitors, the control information is used for controlling the target monitor receiving the control information to close the wireless communication module and the mobile terminal detection module on the target monitor, controlling one of the target monitors to start the warning module, and controlling one of the target monitors not to start the warning module in sequence and with the target duration delayed; specifically, according to the sequence of the residual quantity of the batteries, the corresponding target monitor is controlled from high to low to start the warning module on the target monitor; the target time length is less than the estimated working time length of the warning module supported by the residual battery amount of the last target monitor; after controlling the next target monitor to start the warning module on the next target monitor, controlling the previous target monitor to close the warning module on the next target monitor so as to prevent the two target monitors from being overlapped; of course, both of them can be warned at the same time.

In the receiving step S13, the target monitor receives control information generated by the remote server 82 through a communication line based on the probe information transmitted from the target monitor and/or the probe information transmitted from other fire monitors installed in the same monitored site.

In response to step S14, the mobile terminal detection module and the wireless communication module are turned off and the alarm module is turned on to perform an alarm according to the received control information.

In this embodiment, for the working state of the wireless communication module 5, except that the wireless communication module is started to send the detection information according to the preset time rule, the predetermined key is triggered to start sending the detection information or the smoke detection concentration exceeds the threshold value to start sending the detection information, the wireless communication module 5 is in the power-off state in other time periods, so that the consumption of the high-energy-consumption wireless communication module 5 on the electric energy of the battery is effectively reduced, and the service life of the single battery of the smoke detector is prolonged; the wireless communication module 5 may also employ the NB-IOT module for wireless transmission of data.

After detecting that smoke exceeds a preset threshold value and starting the wireless communication module 5 to transmit data for the first time, the wireless communication module 5 may be restarted according to a preset interval to transmit the detection information or the current detection information acquired within a period of time after the smoke detector is transmitted for the last time, or when the smoke detector is always in a triggered state, that is, the smoke concentration is always over the preset threshold value, the detection information may be transmitted at intervals of a preset time length or continuously transmitted, or when the WIFI detection information is significantly changed, the wireless communication module 5 is started to transmit the detection information, for example, when the detected device becomes a device which cannot be detected, or when the detected device jumps into the detected device. For the condition that the detected equipment becomes undetected equipment, judging whether the MAC address is non-mobile equipment or not by combining power failure information; in the case of a transition from the undetected state to the detected state, this can be considered with a high probability as the MAC address of the mobile terminal, even if its MAC address is not present in the pre-stored address database. Of course, the wireless communication module 5 may be in an operating state after a fire or the like occurs, and transmit the detection information in time until the battery 4 is exhausted. That is, in this embodiment, it may be determined whether the detected MAC address is the MAC address of the mobile terminal by combining the detection time and the time point of the power failure of the monitored location after the fire occurs, and even if the MAC address does not exist in the address library, if the MAC address is detected after the power failure, the device may be considered as the mobile terminal with a high probability, that is, the mobile terminal may also be a device whose MAC address is detected after the power failure of the monitored location.

In order to protect the duration of the warning module in a fire, the battery module 4, the control module 2 and the warning module 23 may be subjected to heat insulation wrapping treatment, and an outlet for warning information, such as a sound emitting port and/or a light emitting port, may be reserved.

In the present embodiment, the remote server 82 constitutes a disaster monitoring apparatus in the present invention, a processing method of the detection information constitutes a disaster monitoring method in the present invention, and a control method of the fire detector constitutes a power management method in the present invention.

Disaster situation monitoring method and device embodiment 2

Acquiring the position range of a target mobile terminal in a monitored place based on the signal strength information of the target mobile terminal and the position information of the current disaster monitor in the monitored place; after the control information is sent, if the change of the central position of the position range of the target mobile terminal exceeds a preset distance according to detection information display sent by other disaster monitors except the target monitor within a preset time, second control information is sent to at least one of the other disaster monitors, and the second control information is used for controlling a warning module on the at least one to carry out warning in a warning mode different from that of the target monitor.

For example, as shown in fig. 7, the remote server 82 on the fire monitoring system 8 receives the detection information sent by the smoke detectors 1 with numbers 1-1, 1-2, 1-3 and 1-4 through the signal transmission of the communication line r, the base station 81 and the communication line r, generates control information based on the processing of the received detection information, sends a control signal to the smoke detector 1 with number 1-2, then sends an alarm to the alarm module on the smoke detector 1 with number 1-2, the smoke detectors 1 with numbers 1-1, 1-3 and 1-4 continue to detect or detect according to a preset scheme under the condition that the battery still has electric energy, sends the detection information to the remote server 82 through the communication line r, the base station 81 and the communication line, only shows the signal transmission of the smoke detector 1 with number 1-1, according to the detection information sent by the mobile terminal, the change of the center of the position range of the target mobile terminal is displayed to exceed more than half of the side length of the monitored place 01, control information is generated and is transmitted to the smoke detector 1 with the number of 1-1 through a communication line, a base station 81 and a communication line, and the smoke detector 1 with the number of 1-2 is warned in a warning mode different from the warning mode of the smoke detector with the number of 1-2, so that the change information is transmitted to the monitored place in a warning mode to prompt rescue workers on site.

In the above embodiment, the disaster monitor for monitoring the fire disaster can also be constructed by using a temperature detector, an open fire detector, and the like.

In the foregoing embodiments, the "fire manifestation" is configured as an inherent physical phenomenon exhibited by the fire itself, and can be detected by a corresponding technical means, such as high temperature, flame, smoke, etc.; the "disaster representation" is configured as an inherent physical phenomenon exhibited by the disaster itself, and includes a disaster representation detected by technical means before the disaster occurs, such as detection before an earthquake occurs, or a disaster representation detected during the disaster occurs, such as shaking of a building in an earthquake, or a disaster representation after the disaster occurs.

The invention has the main idea that the phenomenon that people exist in a place can be represented based on the mobile terminal with the wireless network or the Bluetooth in the open state, and the mobile terminal with the wireless network or the Bluetooth in the open state in a disaster place is detected by using a technical means to judge whether people exist, so that the on-site rescue is effectively assisted. According to the present concept, the structure and operation principle of the detector, the details of the disaster information and the processing means are obviously changed, and are not limited to the above embodiments.
