[0027] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model. In addition, the technical features involved in each embodiment of the utility model described below can be combined with each other as long as they do not conflict with each other.
[0028] Conventional fire evacuation signs are fixed in a fixed direction and do not take into account the location of the fire and the direction of the fire smoke. Once the direction of the sign is the direction of the fire smoke, the evacuees may inhale a large amount of toxic smoke and be poisoned; when the direction of the sign points to the fire area, it will cause the evacuees to mistakenly enter the fire and cause burns. To this end, the utility model provides an intelligent guidance device for fire evacuation direction, which includes a wireless transceiver module, a first signal processor, a second signal processor, a switch and an indicator light wireless transceiver module. The temperature and smoke monitoring intelligent sensor identifies the temperature and smoke concentration of the measuring station. The fire evacuation direction intelligent guidance device receives the temperature and smoke concentration information emitted by the upstream and downstream multiple intelligent sensors in the group to determine the smoke direction and whether the current area is a fire area to determine the fire evacuation direction, and evacuate people to smoke-free, low-smoke, and non-fire directions.
[0029] Furthermore, the fire evacuation direction intelligent guiding device provided by the embodiment of the utility model is as follows: Figure 1 As shown, it includes: a wireless transceiver module, a first signal processor, a second signal processor, a switch and an indicator light;
[0030] The wireless transceiver module is used to receive the ambient temperature and smoke concentration monitored in real time by the temperature and smoke intelligent sensors arranged upstream and downstream of the guide device; that is, the temperature and smoke intelligent sensors are arranged upstream and downstream of the fire evacuation direction intelligent guide device (hereinafter referred to as the guide device) to monitor the ambient temperature and smoke concentration upstream and downstream of the guide device in real time;
[0031] The wireless transceiver module is respectively connected to the temperature and smoke intelligent sensor, the first signal processor, and the second signal processor, and is used to send the ambient temperature to the first signal processor and the smoke concentration to the second signal processor;
[0032] The first signal processor and the second signal processor are both connected to the switch, the first signal processor is used to send a first signal to the switch when the ambient temperature exceeds the temperature threshold, otherwise send a second signal; the second signal processor is used to determine the direction of flue gas flow according to the flue gas concentration; wherein the flue gas flow direction is the direction from high to low flue gas concentration;
[0033] The switch is used to switch the indicated evacuation direction when a second signal is received and the smoke flow direction is consistent with the evacuation direction currently indicated by the indicator light; and to switch the indicated evacuation direction when a first signal is received and the evacuation direction currently indicated by the indicator light is consistent with the direction of the fire area.
[0034] It is worth noting that the evacuation direction should be away from the fire area and the smoke flow direction. When the ambient temperature does not exceed the temperature threshold (for example, 500°C), the area where the guide device is located is considered to be a non-fire area, and it is sufficient to ensure that the evacuation direction is away from the smoke flow direction.
[0035] When the ambient temperature exceeds the temperature threshold (eg 500°C), it is considered that the area where the guide device is located may have a fire source and is a fire area. First, ensure that the evacuation direction is away from the current area (ie the fire area).
[0036] The air temperature and smoke concentration monitoring intelligent sensors and the fire evacuation guidance intelligent device use wireless data transmission and are used in pairs. The fire evacuation guidance intelligent device directly wirelessly receives real-time data sent by multiple air temperature and smoke concentration monitoring intelligent sensors arranged upstream and downstream, and automatically lights up the evacuation direction indicator light after analysis and evaluation. At the same time, the monitored air temperature, smoke concentration and evacuation direction data are marked and sent to the background in real time through the wireless module.
[0037] The intelligent sensor for temperature and smoke monitoring includes a smoke and temperature sensing module, a control module, a wireless transmission module, and a power module. The controller receives the smoke and temperature information sensed by the sensing module in real time, and sends the information to the outside through the wireless transmission module after assigning an identification code. Specifically, the controller drives the smoke and temperature sensing module to sense data and drives the wireless module to send the identified real-time data to the outside. The identification setting module is responsible for the identification setting of the working building, floor, unit and measuring point location of this device. The smoke and temperature sensing module is connected to the temperature and smoke sensitive elements to sense the temperature and smoke concentration data of the monitoring point. After the identification setting module completes the identification of the monitoring data, the controller drives the wireless module to send it. The smoke and temperature sensing module is connected to the smoke concentration and temperature transmitter at the bottom, and the transmitter is connected to the corresponding smoke concentration and temperature sensitive elements; it is connected to the controller at the top, and the perceived smoke concentration and temperature real-time data are transmitted to the controller, and the controller assigns an identification code to it through the identification setting module.
[0038] The guide device includes a wireless transceiver module, a control module, a power module and an indicator light. The wireless transceiver module receives information from the temperature and smoke monitoring intelligent sensors upstream and downstream of the fire evacuation direction intelligent device. The control module identifies, analyzes and evaluates the direction of the fire scene and smoke flow. When the current evacuation direction is consistent with the direction of the fire scene and smoke flow, it sends out a turning information. The evacuation guide module (i.e., the indicator light) changes direction after receiving the information, and at the same time, the evacuation direction information data is marked and sent out through the wireless transceiver module.
[0039] The identification setting module is responsible for setting the floor unit of the building where the device is located, and the wireless transceiver module is responsible for receiving the real-time data sent by the group pair of intelligent sensors and sending the fire evacuation direction identification data. The control module drives the wireless transceiver module to receive the real-time identification data sent by the group pair of intelligent sensors to obtain the fire direction and smoke flow direction, and compares it with the current evacuation direction. When it is inconsistent, the control module changes the indicator light, and at the same time, the data is identified and sent out by the wireless transceiver module. That is, the control module connects the wireless transceiver module, the identification setting module, the evacuation guidance module and the power module. The wireless transceiver module receives the identified data monitored by multiple upstream and downstream smoke and temperature intelligent sensors of the group pair, and transmits it to the control module. The control module determines the smoke flow direction and whether the current area is a fire area, and compares it with the current evacuation direction. When it is inconsistent, the correct evacuation direction light is lit. The control module also drives the wireless transceiver module to send the identified evacuation guidance direction data outward.
[0040] Specifically, the control module includes a first signal processor, a second signal processor, and a switch. The wireless transceiver module is connected to the temperature and smoke intelligent sensor, the first signal processor, and the second signal processor, respectively, and is used to receive the ambient temperature and send it to the first signal processor, and receive the smoke concentration and send it to the second signal processor; the first signal processor and the second signal processor are both connected to the switch, and the first signal processor is used to send a first signal to the switch when the ambient temperature exceeds the temperature threshold, otherwise it sends a second signal; the second signal processor is used to determine the smoke flow direction according to the smoke concentration; wherein the smoke flow direction is the direction from high to low smoke concentration; the switch is used to switch the indicated evacuation direction when the second signal is received and the smoke flow direction is consistent with the evacuation direction currently indicated by the indicator light; and switch the indicated evacuation direction when the first signal is received and the evacuation direction currently indicated by the indicator light is consistent with the direction of the fire area.
[0041] Multiple devices can be arranged according to fire protection design needs, such as corridors and stairwells, thereby forming an intelligent fire monitoring and fire evacuation guidance network in the building.
[0042] Preferably, the indicator light comprises an upstream indicator light and a downstream indicator light;
[0043] The upstream direction indicator light is used to indicate that the evacuation direction is upstream;
[0044] The downstream direction indicator light is used to indicate that the evacuation direction is downstream.
[0045] Preferably, the switch is a relay, the first signal processor is a logic switch, and the second signal processor is a logic switch.
[0046] Preferably, at least two temperature and flue gas intelligent sensors are arranged upstream and downstream of the guide device respectively.
[0047] At least two temperature and smoke smart sensors are arranged upstream and downstream of each guide device to monitor the ambient air temperature and smoke concentration in real time. Since the airflow in the building has a specific flow direction, the smoke flow direction at the fire scene is deterministic.
[0048] The temperature and smoke intelligent sensor can adopt existing sensors, or the temperature and smoke intelligent sensor provided by the utility model. Preferably, the guide device also includes temperature and smoke intelligent sensors arranged upstream and downstream of the guide device, which are used to monitor the ambient temperature and smoke concentration upstream and downstream of the guide device in real time. The temperature and smoke intelligent sensor includes: a smoke and temperature sensing module, a wireless transmission module, and a controller power module;
[0049] The temperature and smoke intelligent sensor includes: a smoke and temperature sensing module, a wireless transmission module and a power supply module;
[0050] The smoke and temperature sensing module is used to obtain the ambient temperature and smoke concentration in real time, and send them to the wireless transceiver module through the wireless sending module.
[0051] Preferably, the temperature and smoke intelligent sensor further comprises an identification setting module for assigning identification codes to the ambient temperature and smoke concentration.
[0052] Preferably, the guiding device further comprises an identification setting module for assigning an identification code to the evacuation direction information.
[0053] When there is no fire smoke information, the temperature and smoke monitoring intelligent sensor sends out a safety message. After the guide device receives the information, the control module controls the evacuation direction light to turn off, reducing energy consumption; when there is fire information, the temperature and smoke intelligent sensor sends out temperature and smoke concentration information, and the guide device receives multi-point real-time temperature and smoke concentration information sent by upstream and downstream temperature and smoke monitoring intelligent sensors, analyzes and determines the smoke flow direction and whether the area is a fire area, and the control module controls the evacuation guidance module to point correctly; when the control module cannot determine whether the area is a fire area or the smoke flow direction, the control module controls the evacuation guidance module to perform two-way indication.
[0054] As an example, Figure 1 As shown, an intelligent building fire evacuation path guidance device provided by an embodiment of the utility model includes 4 temperature and smoke intelligent monitoring sensors, 2 on each side of the left and right sides of the guidance device, and are coded 1, 2, 3, and 4 from right to left.
[0055] For example, in an office building, according to fire protection requirements, there are stairs at both ends of each floor and a walkway in the middle. Figure 4 This is the third floor of the building. A guide device is installed at each stairwell at both ends of each floor, numbered D31 and D34, and two are installed in the middle corridor, numbered D32 and D33. Two temperature and smoke intelligent monitoring sensors are installed on the left and right of each guide device, numbered from left to right, D3iS1 to D3iS4.
[0056] The staircase smart sensors are installed on the same floor, 2 below and 2 above, numbered from bottom to top.
[0057] When the fire is close to D31S1 (fire in the stairwell utility room), the smoke concentration and temperature of D31S1 are the largest, and the temperature of D31S1 exceeds the temperature threshold, that is, the fire source is located at D31S1, D31 is in the fire area, D31S2, D31S3, and D31S4 decrease in sequence, and D31 receives and issues an evacuation guide in the direction away from D31S1, that is, this stairwell should not be used. D32 receives the smoke concentration and temperature data issued by D32S1-D32S4, and their values are from large to small. It is recognized that the fire source is in D31, and the smoke flows to the direction of D31S4. D32 issues an evacuation guide to the left, and D33 and D34 synchronously determine the guide in real time.
[0058] It is easy for those skilled in the art to understand that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
