Description

CCTV-linked disaster information provision and evacuation guidance system {System for providing disaster information and exit guide}

The present invention relates to a disaster information provision and evacuation guidance system, which is linked with a CCTV camera, to a disaster information provision and evacuation guidance system.

Buildings, etc., are provided in dangerous situations such as fire or gas leakage, and emergency doors are provided for emergency evacuation. Emergency doors are usually equipped with an emergency notification device. As the use of heaters increases, the risk of fire increases, and as balcony expansion becomes legal, structural changes are increasing rapidly, and the importance of opening the roof, the only shelter, is increasing.

Accordingly, the automatic emergency door opening/closing system must be installed and maintained in accordance with Article 30-2 of the Fire Service Act and Article 31 of the same Act for the safe evacuation of personnel for various public buildings and multi-use facilities such as buildings, hotels, apartments, and schools.

Buildings and public facilities are equipped with detectors to detect whether a fire has occurred. When the fire detector detects that a fire has occurred, it outputs a signal indicating whether a fire has occurred through the transmitter. The signal output from the transmitter is received by a receiver installed in the central management system of buildings and public facilities. Through this, whether or not a fire has occurred is spread to the entire building and public facilities.

However, these receivers only inform whether a fire has occurred, and cannot guide specific evacuation routes where to evacuate. Therefore, there is a need for a means to efficiently induce evacuation depending on the location of the fire and the situation of the fire.

Therefore, the central control server 300 can receive the monitoring area image and the monitoring area environment value through the IoT hub 200, and transmit the evacuation induction control value to the evacuation guidance guide 130 through the IoT hub 200. do. In addition, when it is determined that a fire has occurred, the central control server generates an evacuation induction control value and transmits the fire alarm to the related terminal registered in advance when it is transmitted to the IoT hub 200. It will be described in detail below.

The surveillance camera 110 is installed for each surveillance area, and photographs an image of the surveillance area and transmits it to the IoT hub 200. As shown in FIG. 2, the surveillance camera 110 may include at least two of a dome camera, a flat camera, a search light camera, a heat detector camera, and a PTZ camera. Accordingly, the surveillance camera 110 may transmit the video of the surveillance area photographed as shown in FIG. 3 to the central control server 300 through the IoT hub 200.

For reference, a dome camera refers to a camera that is attached to the ceiling and has a dome-shaped housing, a flat camera refers to a camera having a columnar structure, a search light camera refers to a camera that illuminates a search light, and a heat detector camera It refers to a camera that detects heat like an infrared camera, and a PTZ camera refers to a camera capable of zooming in and zooming out.

The environmental value detector 120 is installed in a monitoring area where the monitoring camera 110 is located, and is a device that senses the environmental value of the monitoring area and transmits it to the IoT hub 200. As shown in FIG. 2, the environmental value detector 120 may include two or more of a carbon monoxide detector, a motion detector, a door open detector, a fire detector, and a temperature and humidity detector. Accordingly, as shown in FIG. 4, the detected environmental value of the monitoring area may be transmitted to the central control server 300 through the IoT hub 200. Here, the environmental value of the monitoring area is the amount of carbon monoxide detected by the carbon monoxide detector, whether or not motion is detected by the motion detector, whether the door is opened or closed by the door open detector, the amount of smoke detected through the fire detector, and the temperature and humidity detector. Temperature or humidity sensed through may be applicable.

The evacuation guidance guide 130 is installed in the monitoring area where the camera and the environmental value detector 120 are located, and guides the evacuation guidance according to the evacuation guidance control value received from the central control server 300 through the IoT hub 200 It is a device that performs. The evacuation guidance guide 130 may include two or more of an emergency bell, a warning light, and a fire notification repeater (fire notification speaker), as shown in FIG. 2. Accordingly, the evacuation induction control value may be received from the central control server 300 through the IoT hub 200 detected as shown in FIG. 5.

The IoT hub 200 is installed in a surveillance area in which IoT sensors such as a surveillance camera 110, an environmental value detector 120, and an evacuation guide 130 are located, and a surveillance area received from the surveillance camera 110 The image and the environmental value of the monitoring area received from the environmental value detector 120 are transmitted to the central control server 300, and the evacuation induction control value received from the central control server 300 is received to induce the evacuation of each monitoring area. It is a hub set-top box transmitted to the guide 130. For reference, the surveillance camera 110 may be connected to the IoT hub 200 by wire, and the environment value detector 120 and the evacuation guide guide 130 may be connected to the IoT hub 200 through an IoT wireless transceiver.

The IoT hub 200 (IoT HUB), which can respond to all sites, follows the traditional CCTV recording method, and uses the FEN (For Every Network) system to give a unique ID at the site, and the ID set previously in control or mobile It is used by registering and entering user ID and password. In this way, a total of 10 IoT sensors such as various surveillance cameras 110, environmental value detectors 120, and evacuation guide guides 130 can be easily registered for each monitoring area. Communication with IoT sensors such as various surveillance cameras 110, environmental value detectors 120, and evacuation guides 130 is 47.8625 MHz, and a receiver (model name: SUD-10) is used in the USB port, and one-way or two-way ( It is a half-duplex communication method), and the communication period is different according to the type of the sensor, and the number of communication is set to avoid mutual interference and communication leakage. Direct communication between the IoT sensor and the transceiver is possible, and the distance increases when a wireless repeater is used, and the distance can be infinitely increased regardless of wiring or piping according to the repeater design in the field. Of course, if the receiver is removed from the IoT hub 200, it can be used as a general CCTV recorder.

The central control server 300 is a DDNS (Dynamic Domain Name System)-based server and may be used when the IP of the domain is flexible. Even if the IP is changed, the domain value set by DDNS does not change, so it is easily accessible.

The central control server 300 determines whether a fire has occurred based on the monitoring area image and the monitoring area environment value received from the IoT hub 200. If it is determined that a fire has occurred, an evacuation induction control value is generated and transmitted to the evacuation guidance guide 130 through the IoT hub 200. In addition, when it is determined that a fire has occurred, the fire alarm is transmitted to the related terminal registered in advance when the evacuation induction control value is generated and transmitted.

In particular, the central control server 300 determines whether a fire occurs based on the surveillance area image and the surveillance area environment value, when the surveillance area image satisfies the first threshold condition set in advance, and the surveillance area environment value is set in advance. 2 If the critical conditions are met, it is judged as a fire. For example, as a result of image analysis of the received surveillance area image, the first threshold condition is detected in which flames larger than the set size are detected, and the amount of smoke that is higher than the set amount of smoke is detected with the environment value of the received surveillance area. If the second critical condition is satisfied, it is judged as a fire. It is possible to accurately determine the occurrence of fire by using the monitoring area image and the monitoring area environment value as the fire occurrence judgment data value at the same time without using any one sensing value.

In addition, when it is judged that a fire has occurred, the evacuation guidance control value is determined by considering the monitoring area image and the monitoring area environment value. For example, when a fire occurs in the first monitoring area, an evacuation induction control value can be generated to evacuate to the second monitoring area where no fire has occurred.

On the other hand, there are a plurality of IoT sensors such as the surveillance camera 110, the environmental value detector 120, and the evacuation guide 130 connected to the IoT hub 200, and each of these IoT sensors is individually turned on/off. It needs to be controlled to be. For example, assuming that 10 surveillance cameras 110 are installed in a surveillance area, it is not necessary to drive all of these 10 surveillance cameras 110. It is necessary to drive only the necessary monitoring camera 110 according to the situation as ON and the remaining monitoring camera 110 to be turned off.

To this end, the central control server 300 provides individual control values for on/off monitoring cameras that individually control each of the dome camera, flat camera, search light camera, thermal sensor camera, and PTZ camera on/off through the IoT hub 200. It transmits to each surveillance camera 110. Similarly, the environmental value detector that individually controls on/off each of the carbon monoxide detector, motion detector, door opening detector, fire detector, and temperature/humidity detector is transmitted to each environmental value detector 120 through the IoT hub 200. do. Similarly, an evacuation induction control value that individually controls on/off each of the emergency bells, warning lights, and fire notification repeaters is transmitted to each evacuation guidance guide 130 through the IoT hub 200.

The central control server 300, in determining the evacuation induction control value by considering the monitoring area environment value and the monitoring area image together, the monitoring camera on/off individual control value determined according to the monitoring area image and the monitoring area environment value, Environment Value Detector On/Off Lets you determine individual control values.

That is, when the central control server 300 fails to determine whether or not the first threshold condition of the surveillance area image is satisfied because the surveillance area image is less than the set image detection reference amount, the central control server 300 is within the surveillance area until it is possible to determine whether the first critical condition is satisfied. A surveillance camera on/off individual control value is generated that incrementally increases the number of on/off operations of the surveillance camera 110 one by one.

For example, assuming that a dome camera, flat camera, searchlight camera, heat detector camera, and PTZ camera are installed in surveillance area A, only dome cameras and flat cameras installed in surveillance area A are acquired by driving ON. When the image analysis result of one surveillance area image is blurred and it is impossible to read the image whether or not the first critical condition is satisfied, the other searchlight camera installed in the surveillance area A is turned on to illuminate the searchlight to acquire the surveillance image. 1 Determine whether the critical conditions are satisfied. If it is still not possible, the PTZ camera is additionally turned ON to enlarge and shoot.

Likewise, the central control server 300, when the monitoring area environment value is less than the set environment value detection reference amount and cannot determine whether the monitoring area environment value meets the second threshold condition, until it is possible to determine whether the second critical condition is satisfied. An environmental value ON/OFF individual control value is generated that increases the number of ON operations of the environmental value detector 120 in the monitoring area by one.

However, in the case of a preset emergency situation, the central control server 300 exceptionally sets the number of ON operations of the surveillance camera 110 in the surveillance area not one by one until it is possible to determine whether the first threshold condition is satisfied. Create individual control values for on/off surveillance cameras in increments of two.

For example, when the surveillance area is a VIP accommodation area, the surveillance camera on/off individual control value is generated to increase by two exceptionally for quick judgment.

Similarly, in case of a preset emergency, the central control server 300 exceptionally increases the number of ON operations of the environmental value detector 120 in the monitoring area until it is possible to determine whether the second threshold condition is satisfied. Instead, create an environment value on/off individual control value that increases by two.

Meanwhile, the present invention is implemented to have various features as follows in addition to the above-described contents.

1) Various types of IoT sensors

Wired and wireless transmission sensors that receive and transmit emergency signals from fire/carbon monoxide detectors, wired and wireless transmission sensors that transmit signals from P-type receivers/fire receivers, temperature-humidity sensors that freely set the temperature according to the environment and product of the site, and LEDs that operate in emergencies. Wireless warning light, wireless repeater accommodating all sensors, transceiver mounted on USB of NVR or DVR, emergency bell for siren transmission wirelessly, emergency bell with name tag worn on clothing, wireless PIR sensor for intrusion detection, power failure or smoke in case of fire When it is impossible to secure the field of view, a searchlight camera for securing a path and an FPGA dedicated to image analysis algorithms are installed, and a flame detection camera that doubles alerts by combining with an IoT sensor is provided. Each IoT sensor is composed of constant power, battery only, power + battery, and transmits a low battery signal. All signals are transmitted from CCTV to video information and events through a network, and transmitted from the central control server 300 to customers and control centers, and can be configured as an algorithm that is processed by the operating personnel as necessary. When smoke, flame, or emergency event is detected, only 1 byte of Meta data information is sent per sensor, so unlike the existing method of analyzing and sending from the server, it does not create a load on the network.

2) Solutions for safety by adding security

When an emergency occurs, various IoT sensors are activated and an emergency bell is pressed, and video information is delivered to the manager through integrated control and Push/SMS/MMS to notify the emergency situation and take action. When a fire detection sensor is detected, video information, address, and phone number can be transmitted to the integrated center, and CCTV and Internet management of objects are possible in the area. Using connected sensors and cameras in the field, valuable property and life can be protected. Even on sites that are not operated 24 hours a day, the “border/release” system using sensors connected to the physical/virtual keypad can ensure stability after the customer leaves work. Of course, the sensors belonging to fire/emergency bell/temperature/humidity are designed to operate at any time regardless of the “border/release” system, so it is not only dependent on the image analysis or server, which can vary according to the site situation, intuitive information delivery and evacuation security notification This is possible.

3) IoT sensor operation algorithm

The operation of IoT sensors, such as the surveillance camera 110, the environmental sensor 120, and the evacuation guide guide 130, does not generate unnecessary data and power consumption without detection. IoT sensors such as the surveillance camera 110, the environmental value detector 120, and the evacuation guide guide 130 use communication of 47.8625 MHz, and generate a total of 3 transmissions when an event occurs. The total time for 3 occurrences is 0.38 seconds. One time is 01 seconds, and the difference time between the number and the number is 0.04 seconds. (The above time can be changed according to customer's request) The transceiver can receive information from the IoT sensor at the same time, and receives 20 sensor information at the same time. Data can be sequentially transmitted to NVR or DVR within 1 second.

In the case of a temperature/humidity sensor, the temperature is transmitted in 5 minutes increments between -30 degrees and +70 degrees. After that, MCU Slep and RF Shutdown 5 minutes before. The set temperature is set in the NVR or DVR according to the site, and when the set temperature value is exceeded or lowered, the IoT hub 200 transmits it to the central control server 300. The sensor in charge of access control transmits the registration information and boundary/release information of the keypad to the NVR or DVR in a two-way (half-duplex communication method) communication method, and the central control server 300 stores the DB. On/of of the physical door is managed by the keypad, and control in the App/Web is managed by the central control server 300. Temperature and humidity data is transmitted until ACK is received. A battery-operated IoT sensor transmits Low Bat RF data when it enters below 2,5V of the battery. This method does not require running the image analysis algorithm on the server.

4) Universality and alarm function

In addition to CCTV and disaster occurrence algorithms, intrusion detection algorithms are also installed, so it can be used for disaster prevention or security CCTV. In the event of various events and intrusion detection, the product notifies the manager in various ways, and when a warning lamp is connected, it is notified through the warning lamp, and when a speaker is connected to the monitoring system, it notifies the fire detection through the speaker. In addition, when the administrator's e-mail or phone number is registered, e-mail and text messages are sent through it, and if a smartphone application is used, a push message can be sent to immediately check the video of the camera.
