LS À SMART EMERGENCY EVACUATION INDICATING SYSTEM AND lu101335
METHOD FOR A METRO STATION Technical Field | The present invention relates to the techmical field of urban rail transmit operation and management. More specifically, the present invention is a smart emergency evacuation indicating system and method for a metro station. Background | As China’s economy steadily grows, and urbanization is increasing, metro lines | are increasing in more and more cities. However, as a typical underground building, a metro station may suffer from many emergencies, wherein fire accident is the most common one. Once a fire accident occurs, crowd evacuation is a vital problem. Stampede caused by delayed evacuation has been frequently reported in recent years. Fires may spread rapidly, simply leaving a short time for escape. While in a metro station, crowd density is extremely large, something completely irrelevant | readily tends to induce mass panic and crowds, and people run around to cause a stampede, resulting in casualties. Currently, there are two main metro station evacuation indicating systems. One is | pre-bury evacuation indicating signs according to a shortest evacuation route principle. | The other is to make an evacuation plan by a fire control system according to an initial position of a fire source. The above two systems neglect the effect of smoke | spread on an evacuation route during a dynamic fire process. Smoke spread of fire | happening in a metro station is related to the position of the fire source, the power of the fire source, and ambient surroundings. Therefore, it is difficult to predict a fire spread path in advance. Once fire smoke spreads in the same direction as an evacuation direction, or even into an evacuation passageway, high-temperature smoke is extremely prone to cause human body injury and lower evacuation efficiency. | When an emergency happens, relying on the existing fire fighting equipment and evacuation method cannot effectively avoid and solve the above-mentioned problems. 1 ee — ">"

Detailed Description of the Embodiments | The specific implementations of the present invention will be further describedin detail below with reference to the drawings and embodiments.
The following | embodiments are simply used for illustrating the present invention, rather than : limiting the scope of the present invention. | Based on previous cases of metro fires, metro fires have the characteristics of including high volume of smoke, fast diffusion of hot smoke, etc. which have a | serious impact on crowd evacuation.
Currently, there are two main metro station | evacuation indicating systems.
One is pre-bury evacuation indicating signs according | to a shortest evacuation route principle.
The other is to make an evacuation plan by a : :
| fire control system according to an initial position of a fire source.
The above two lu101335 | systems neglect the effect of smoke spread on an evacuation route during a dynamic . fire process.
Smoke spread of fire happening in a metro station is related to the | position of the fire source, the power of the fire source, and ambient surroundings.
Therefore, it is difficult to predict a fire spread path in advance.
Once fire smoke spreads in the same direction as an evacuation direction, or even into an evacuation i passageway, high-temperature smoke is extremely prone to cause human body injury and lower evacuation efficiency.
Consequently, it is quite urgent to solve the problem | of rapid evacuation eluding fire smoke in metro fires. | In order to solve the above-mentioned problem, in the present embodiment, as : shown in FIG. 1, a smart emergency evacuation indicating system for a metro station | is provided, including the integrated detection module 1, the central control module 2, | and the multi-information smart indicating module 3. { The integrated detection module 1 is configured for monitoring various regions in the metro station in real time, and instantly sending obtained ambient data to the | central control module 2. Ambient parameters including temperature, visibility, smoke | particle density, etc. are monitored. i The central control module 2 is configured to analyze and process the ambient data.
According to monitoring data of various regions reaching a risk threshold or not, ! a fire region or a smoke diffusion region is determined.
Further, an evacuation route is i updated in real time according to the determining results, and evacuation instruction is sent to the multi-information smart indicating module 3. | The multi-information smart indicating module 3 is configured for guiding the crowd evacuation in real time in the metro station according to the evacuation instruction.
In the present embodiment, the integrated detection module 1 is arranged in a i metro station platform, a waiting hall and various exits, configured for monitoring : fires, collecting various real-time fire data of various regions in the metro station in i the case of fire, and sending the various real-time fire data to the central control module 2. The central control module 2 receives and processes the real-time fire data |
% |sent by the integrated detection module 1, and according to the monitoring data of the lu101335 various regions reaching a limit value affecting crowd evacuation (ie, a risk | threshold) or not, a fire region or a smoke diffusion region is determined.
If the ] monitoring data sent to the central control module 2 by the integrated detection | module 1 in a region goes beyond a preset parameter upper limit value, the region is determined as a “risk region”, otherwise, as a “passable region”. In the present embodiment, risk thresholds of various data monitored by the integrated detection | module 1 are set in advance in the central control module, which are used as standards | for judging states of various regions.
The central control module 2 updates the | evacuation route in real time according to the judging result, and sends the evacuation | instruction to the multi-information smart indicating module 3. Since fires spread | readily, in the present invention, through monitoring ambient data in real time, it is i capable of judging various regions passable or not, adjusting the evacuation route in : real time, quickly detecting fires and intelligently planning the evacuation route in | real time.
Moreover, through collecting and analyzing data related to a metro station i platform, a waiting hall, and various passages in real time, and according to data processing results, the evacuation indicating route can be updated in real time, which can effectively prevent people during an evacuation process from entering a fire i smoke spread region by mistake, and greatly increasing evacuation efficiency and safety.

The smoke sensing unit 101 is configured for monitoring a smoke concentration |in a corresponding region. i The temperature sensing unit 103 is configured for monitoring a smoke : temperature in a corresponding region. | The visibility detecting unit 102 is configured for measuring a visibility in a ;

corresponding region. lu101335 | In the present embodiment, the integrated detection module 1 is arranged in the | metro station platform, the waiting hall and the various exits, configured for | monitoring fires, collecting the various real-time data of the various regions in the | metro station in the case of fire, and sending the various real-time fire data to the | central control module 2.

The upper smoke sensing unit 101 is arranged at a top of the metro station platform, a top of the waiting hall and a top of each exit, and the lower smoke sensing unit 101 is arranged at a i position having the risk height from the ground. 3 In the present embodiment, the smoke sensing unit 101 is arranged in two layers. | The upper smoke sensing unit 101 is arranged at the top of the metro station platform, i the top of the waiting hall and the tops of the various exits, configured for detecting | the fire region. The lower smoke sensing unit 101 is arranged at the position having i the risk height, configured for monitoring the smoke concentrations of the metro station platform, the waiting hall and the various exits at the positions having the set | risk height, and sending the real-time monitoring data to the central control module 2. | Specifically, the risk height is set according to human’s heights, ranging from 1.8 m to i In the present embodiment, as shown in FIG. 2, the integrated detection module | 1 is mounted on a support column in the metro station. Since the integrated detection 6 È
| module 1 is internally provided with the visibility detecting unit 102 and the u101335 temperature sensing unit 103 for monitoring the smoke height and temperature, the | integrated detection module 1 is mounted at a position 2 m from the ground, ; configured for monitoring the smoke diffusion.
Meanwhile, ceilings of the metro station platform and the waiting hall are respectively provided with the smoke sensing | unit 101, configured for detecting and determining the fire position. ] In the present embodiment, the upper smoke sensing units 101 of the smoke i sensing unit 101 are arranged at the tops of the metro station platform, the waiting hall i and the various exits at a certain interval, for detecting and determining the fire region.
The lower smoke sensing unit 101, the visibility detecting unit 102, the temperature | sensing unit 103 are arranged at a certain interval at the positions having the set risk | height, of the metro station platform, the waiting hall and the various exits, configured : for monitoring the smoke concentrations, at the positions having the set risk height, of | the metro station platform, the waiting hall and the various exits.
The smoke sensing | unit 101, the visibility detecting unit 102, and the temperature sensing unit 103 : interact with the central control module 2 through the communication unit 201. | Based on the above embodiments, the crowd flow detecting unit is further | included, for detecting a crowd flow volume in the evacuation route.
Due to the high | crowd density in the metro station, evacuation along a single direction is prone to i inducing excessive crowding and stampede, causing a man-made secondary disaster.
Therefore, in the present embodiment, through detecting the crowd flow volume, the | crowd flow volume and the maximum crowd flow volume of the evacuation i passageway are used as references for the evacuation route, so as to perform the ‘ crowd evacuation in a shunted manner. : Based on the above embodiments, the central control module 2 includes the central control host 203, the control interface 202, the power supply management unit | 204 and the communication unit 201. | The central control host 203 is configured for analyzing and processing the | | ambient data.
According to the monitoring data reaching the risk threshold or not, the | fire region or the smoke diffusion region is determined.
Avoiding passing through the | 7 ii |fire region and evacuating toward risk region or the smoke diffusion region, and u101335 according to the shortest evacuation route principle, the evacuation route is updated in real time.
The control interface 202 is configured for showing the evacuation route of the . : central control host 203 and a curve of the real-time ambient data, including smoke concentration curves of the various regions, smoke temperature curves of the various regions, and visibility curves of the various regions, and controlling the central control | host 203. i The power supply management unit 204 is configured for supplying power for |the central control host 203. | The communication unit 201 is configured for communication connections of the | integrated detection module 1, the central control module 2 and the multi-information | smart indicating module 3. ; In the present embodiment, the central control host 203 of the central control | module 2 analyzes and processes the ambient data, and determines the actual ambient | state according to the processing result.
Staff can check the processing result of the central control host 203 through the control interface 202, and operate the central i control host 203 through the control interface 202, such as parameter setting, | automatic/manual mode switching, etc.
In the present embodiment, the control | interface 202 is further configured for interaction between the staff and the central | control host 203. Through the control interface 202, the staff can introduce metro | station layout into the central control host 203, input related parameters, set related | configurations, carry out region division on the metro station, Moreover, the i evacuation indicating route map planned by the central control host 203 and the real-time monitoring data curves can be checked by the control interface 202, and the i staff can switch the manual/automatic mode of the central control module 2 by the | control interface 202, : Based on the above embodiments, the central control host 203 judges the smoke : diffusion region and smoke diffusion trend according to the monitoring values of the | various smoke sensing units at every moment and variations thereof.
In the present 8 3
1}
invention, at the moment of to, the smoke sensing unit A, the smoke sensing unit B, lu101335 | and the smoke sensing unit C are arranged vertically in three adjacent regions (region È B is located between regions À and C, and there is no other region surrounding the | three regions), wherein if the monitoring value of the smoke sensing unit B is larger than the preset threshold, then the region B is determined as a risk region; at the i moment of ti, the monitoring values of the smoke sensing unit A and the smoke | sensing unit B are larger than the preset threshold, and the monitoring value of the i smoke sensing unit B is greater than that of the smoke sensing unit A, then it can be i concluded that the smoke spreads from the region B to the region A.
For example, at the moment of to, ten data are obtained by ten smoke sensing | units, at the moment of ti, another ten data are acquired, and next at the moments of tz, à t3......, data are continued to be obtained.
First, according to the monitoring values, | the smoke diffusion region can be determined; second, according to variations at various moments, the smoke diffusion trend can be inferred, thus performing a Î prejudge. | Based on the above embodiments, the fire region is the region in which the | monitoring data of the upper smoke sensing unit 101 is larger than the preset smoke | threshold.
The risk region is the region in which any one of the data monitored by the i integrated detection module is greater than the preset threshold. | Based on the above embodiments, the multi-information smart indicating module | 3 includes the evacuation indicating sign 304, the evacuation information screen 303, | the voice broadcast device 302, and the indicating light 301. | The evacuation indicating sign 304 is arranged on the ground of the metro station | platform, the waiting hall and the various passages, configured for updating the indicating direction in real time according to the evacuation instruction of the central | control module 2, and guiding the crowd evacuation according to the latest evacuation : route.
The evacuation indicating signs 304 are mounted at an interval of 5-10 m. : The evacuation information screen 303 is configured for issuing fire information : to the crowds, and guiding the crowd evacuation. ; The voice broadcast device 302 is configured for broadcasting related notices to | 9 3 3the crowds, and guiding the crowd evacuation. lu101335 | The indicating light 301 is arranged at the tops of the entrances and exits of the Ÿ metro station, for switching color according to the control of the central control : module 2 to forewarn the fire evacuation. | In the present embodiment, the evacuation indicating signs 304 are arranged at | |an interval of 5-10 m on the ground of the metro station platform, the waiting hall and the various exits, for guiding the crowd evacuation according to the evacuation Ë instructing route planned by the central control module 2, and switching indicting direction according to the instruction sent by the central control module 2. The | evacuation indicating sign 304 can indicate eight directions, as shown in FIG. 3. In | FIG. 3, (a) is a state diagram of the evacuation indicating sign 304 in a normal state, i and (b) is a state diagram of a route indication in a fire condition.
The black arrow in Ë the figure indicates the evacuation direction, and in actual application, the arrow is | green. i Based on the above embodiments, the indicating light 301 can switch between itwo different colors of red and green, and show corresponding color according to the | information sent by the central control module 2. When the monitoring data of the i integrated detection module 1 at various entrances and exits exceeds the preset i parameter upper limit, the indicating light 301 shows red, representing the entrance | and exit is not available for evacuation.
When the monitoring data of the integrated | | detection module 1 at various entrances and exits does not exceed the preset i parameter upper limit, the indicating light 301 shows green, representing the entrance | | and exit is available for evacuation.
Ë In the present embodiment, the indicating light 301 is arranged at the tops of the Ë various entrances and exits, capable of showing two different colors.
When the i monitoring data of the integrated detection module 1 at various entrances and exits of | the metro station is greater than the preset parameter upper limit, the indicating light ; : 301 shows red, representing the entrance and exit is not available for evacuation. | When the monitoring data of the integrated detection module 1 at various entrances | | and exits does not exceed the preset parameter upper limit, the indicating light 301 | : |
È shows green, representing the entrance and exit is available for evacuation. At the lu101335 | same time, the central control module 2 issues the evacuation information through the | evacuation information screen 303 and the voice broadcast device 302. The | evacuation information screen 303 can be replaced by urban rail transit PIS system, ; and the central control module 2 cooperates with the urban rail transit PIS system. ! The voice broadcast device 302 can be the broadcast device currently available in the metro station.
Based on the above embodiments, in the present embodiment, avoiding passing through the fire region and evacuating toward risk region or the smoke diffusion region, and according to the shortest evacuation route principle, the evacuation instruction is made by the evacuation indicating method, and the evacuation route is updated in real time.
As shown in FIG. 4, taking a metro station platform as an example, the | evacuation indicating method is as follows. |
1. As shown in FIG. 4(a), according to the position where the integrated | detection module 1 is arranged, the metro station platform is divided into different regions and each region is numbered, and each region includes only one integrated È detection module 1. The region division result is input into the central control module i 2, and meanwhile the indicating light 301 and the evacuation indicating sign 304 are | associated with the numbering of corresponding region, so as to enable the central control module 2 to rapidly locate the fire region and accurately send instruction ; signals to the indicating light 301 and the evacuation indicating sign 304. |
2. The monitoring data of the various regions detected by the integrated detection : module 1 is transmitted to the central control module 2 in real time.
3. Since the integrated detection module 1 simply covers the region where the | integrated detection module is located, if the monitoring data sent to the central control host 203 by the integrated detection module 1 in a certain region is greater than the preset parameter upper limit, then the region can be determined as a “risk : region”, otherwise, as a “passable region”. The region determined as a “risk region” will not be used for evacuation, while the “passable region” is available. | 11 bo i
&
4. As shown in FIG. 4(b), the monitoring data sent to the central control host 203 lu101335 | by the integrated detection module 1 in the region 12 is larger than the preset parameter upper limit, while the monitoring data of the integrated detection module in Ë other regions is normal, then it can be considered that fire accident occurs in the f region, and the region is determined as a “risk region”. Subsequently, the monitoring Ë data sent to the central control host 203 by the integrated detection module 1 in the i adjacent region 10 is also greater that the preset parameter upper limit, then it is | concluded that fire smoke has already spread from the region 12 to the region 10, and ; the region can also be regarded as a “risk region”. | |
5. The above determining processing is parallel computation, and the | determinations of all the integrated detection modules 1 in corresponding regions with | a time period are carried out simultaneously. ; As shown in FIG. 5(a), the metro station platform 18 and the metro station i platform 2 are determined as “risk regions” by the central control module 2, and when | the route for the evacuation route is required to be planned, the method for making the | evacuation route is as follows: | 1) determining available exit. The staff need to set the position of the safety exit : in advance through the control interface, namely, associating the safety exit with the i numbering of the region where the safety exit is located. In a real-time monitoring | process, if the central control host 203 determines a region where a safety exit is i located as a “risk region”, then the safety exit is regarded as unavailable. In FIG. 5(a), i an entrance of the escalator A is located in the region 18, so the escalator A is i determined as a non-safety exit, crowd evacuation through the escalator A is | forbidden, instead, the crowds can be merely evacuated through the escalator B to the | waiting hall; ! 2) planning evacuation route according to principles of a shortest evacuation i route passing through a “passable region” and avoiding a “risk region” to a safety exit | and a relatively simple evacuation route (reduce curved lines). Since the region 20 is : determined as a “risk region”, people in the region 22 cannot be evacuated toward the | escalator B through the region 20, instead, people in the region 22 should be | 12 : . TT TTevacuated toward the escalator B successively through the region 21 and the region 19. lu101335 { Similarly, for people in the other “passable region”, the evacuation route is planned according to the principle of evacuating to an adjacent “passable region” closest to a safety exit and then evacuating toward the safety exit. People in a “risk region” are evacuated to a “passable region” closest to the region they stayed and most | conductive to later evacuation, and then evacuated out. For example, for people in the region 18, the adjacent “passable regions” are the region 16 and the region 17, | wherein the region 16 is closest to a safety exit, therefore, people can be evacuated to the region 16 first and then toward the safety exit; 3) as shown in FIG. 5(b), the central control host 203 plans the evacuation route | according to the determining result, after that, the central control host 203 send | signals to the evacuation indicating sign 304, the evacuation indicating sign 304 | located in a “risk region” directs to the closest passable region, and the evacuation indicating sign 304 located in “passable region” directs to an adjacent passable region | closest to a safety exit. The indicating light 301 is respectively provided on two sides | of the safety exit and an exit of passageway, if the central control host 203 determines a region where the safety exit and the exit of a passageway are located is a “risk region”, then the indicating lights 301 on both sides turn red, if is a “passable region”, the indicating lights 301 on both sides turn green; 4) the integrated detection module 1 continuously monitoring the various regions during an evacuation process and sending monitoring data to the central control | module 203, and the central control module 2 repeats the steps 1), 2) and 3) to adjust . and update the evacuation route in real time, preventing fire smoke causing human body injury during the evacuation process.
As shown in FIG. 6, a fire accident occurs in a security check region of the waiting hall of a metro station. The central control module 203 determines the regions 4, 7, 10, 11, 13 and 16 in FIG. 6 as “risk regions” according to monitoring data sent back by the integrated detection module 1. Since the entrance A is located in the region 4, the entrance A is determined as unavailable. The central control host 203 plans the evacuation route according to the real-time determining result, and sends 13 — I TITI TITI TOO)
signals to the evacuation indicating sign 304 and the indicating light 301. The lu101335 evacuation indicating sign 304 and the indicating light 301 act according to signal instruction, the evacuation indicating sign 304 located in a “risk region” directs to the closest passable region, and the evacuation indicating sign 304 located in a “passable region” directs to an adjacent passable region closest to a safety exit. Since the entrance À is unavailable, the indicating light 301 in front of the entrance À turns red, | the rest of the entrances are available normally, and the corresponding indicating lights 301 turn green. The integrated detection module 1 continuously monitors the various regions during the evacuation process and sends monitoring data to the central control module 2, and the central control module 2 adjusts and updates the evacuation route in real time according to the monitoring data. The present embodiment further provides a smart emergency evacuation indicating method for a metro station based on the smart emergency evacuation ‘ indicating system in the above embodiments, including: : the integrated detection module monitoring various regions in the metro station / in real time, and instantly sending obtained ambient data to the central control ) module; ; the central control module analyzing and processing the ambient data, according : to monitoring data of the various regions reaching a risk threshold or not, determining a fire region or a smoke diffusion region, updating an evacuation route in real time : according to a determining result, and sending an evacuation instruction to the ' multi-information smart indicating module; : the multi-information smart indicating module guiding a crowd evacuation in | real time in the metro station according to the evacuation instruction. | In summary, according to the smart emergency evacuation indicating system and ; | method for the metro station provided by the embodiments of the present invention, it ; is likely to quickly detect a fire accident in the metro station and intelligently plan the | evacuation route in real time. Through collecting and analyzing data related to the ; metro station platform, the waiting hall, and various passages in real time, and | according to data processing results, the evacuation indicating route can be updated in j 14
