technical field

The invention relates to the technical field of fire prevention and control, in particular to a smart fire remote monitoring system based on the Internet of Things.

Background technique

At present, the "fire-fighting system" used for fire fighting can be called an intelligent fire-fighting system, which is far from meeting the requirements of an intelligent fire-fighting system. Its shortcomings are: 1. Lack of effective perception. Whether it is firefighting and rescue work, or supervision and inspection work, we often use manual perception more often. For example, when the people make fire alarms, they often use telephone inquiries to understand the information on the fire scene. However, due to the lack of professional knowledge of the alarm personnel, we cannot grasp effective information in the first time to support the firefighting and rescue work; another example is fire supervision. The inspection work requires our supervision and inspection personnel to collect information on the spot of the unit, which is limited in time and space, resulting in low inspection efficiency. 2. Lack of effective information sharing. The construction of "smart fire protection" requires information from all aspects to support the operation of fire protection, especially firefighting and rescue work. The exchange of information, such as the fire safety household registration system, only realizes the regular exchange of internal and external network information. 3. Widely distributed nine small places and various business places (large shopping malls, supermarkets; stations, hospitals, hotels, etc.; labor-intensive enterprises; flammable and explosive warehouses; wood processing, textiles, dust-related, spraying, pharmaceuticals, etc. Enterprises; bars, Internet cafes and other entertainment venues; small restaurants, stores, and various small and micro enterprises.), schools, hospitals and other scenarios cannot effectively supervise smart fire protection, and each business place needs external or part-time related electricians, and the labor cost is high. .

The fire-fighting equipment module 11 senses the position status information of fire-fighting equipment and fire-fighting facilities through tags, and the status information of fire-fighting equipment includes electrical fire detector current and voltage information, wire and cable temperature information, fault arc status, fire door switch status, fire-fighting pool water tank Liquid level information, smoke detector smoke information, and status information of fire-fighting facilities include the purchase time, expiration time, installation time, person in charge, and inspection times of fire-fighting equipment such as fire extinguishers, fire-fighting folding ladders, and mini-fire stations. The location status information of the fire-fighting equipment and fire-fighting facilities is uniformly stored in the server of the remote monitoring and management center. When the fire-fighting equipment detects abnormal information, it will send a text message to the mobile phone of the relevant personnel or person in charge of the unit to remind them to replace , and transmit the abnormal information to the GIS map information module. The fire management department arranges the inspection plan and sampling inspection plan of each networked building, and the system automatically generates SMS content according to the plan, reminding the person in charge of fire protection (department) to carry out the inspection of fire equipment.

The traditional fire-fighting water system is not required to be included in the system monitoring, but only regulates the fire-fighting water pipe network, water source, pressure and water supply. In dangerous situations, when using fire-fighting water for fire fighting, there may be problems such as insufficient fire-fighting water source, insufficient pressure, and water leakage in the pipe network, causing huge hidden dangers to fire-fighting. After the fire-fighting water system is included in the platform monitoring, the fire-fighting water module 12 monitors the pressure, liquid level, water leakage and cover opening of the fire-fighting water pipe network in real time. The alarm can be issued in a timely manner, so that the relevant personnel can repair and maintain it in time to ensure fire safety. Power supply, fault, start-stop and manual/automatic status information in the pump control cabinet; install pressure sensors in the main network to collect real-time pressure information in the main network; install sensors at each valve to collect valve opening and closing status information in real time; in the roof water tank A sensor is installed to collect the water volume information of the water tank in real time; a pressure sensor is installed at the end water test device to collect the real-time pressure information of the end in real time. The system can quickly find abnormalities and faults by analyzing data information, retrieving on-site video and other methods, effectively reducing the number of on-site inspections of fire water, reducing work intensity, improving work efficiency, and ensuring that the fire water system plays a real role in the event of a fire.

The independent smoke and gas detection module 13 realizes data collection of smoke, harmful gas, and gas fire extinguishing information through a highly sensitive wireless smoke alarm device, and detects smoke in real time in seconds. Once it is found that the monitoring number exceeds the risk threshold, the APP will , SMS alarm, telephone alarm are all on the battle, through the device's label, geographical location, quickly notify the owner, the fire department of the property where the fire is hidden.

The fire-fighting power supply module 14 monitors the power supply working status of each component of the fire-fighting system (such as the fire-fighting alarm host, floor display, water pump, spray pump, elevator, etc.) , undervoltage, overcurrent, short circuit, open circuit and other fault alarm prompts; can record voltage and current operating parameters for a long time, automatically analyze the operating state of the fire power supply for a period of time, and warn the hidden dangers of possible output problems.

After receiving the alarm information of each subsystem of the sensing terminal, the data center of the video monitoring module 16 can adjust the monitoring camera image associated with the alarm location, and view the video of the alarm site to assist in confirming the fire situation. It realizes the organic combination of fire alarm subsystem, fire water subsystem, electrical fire subsystem, smoke prevention and exhaust subsystem, fire equipment power supply subsystem, fire door subsystem and video monitoring subsystem, and realizes the linkage between alarm points and monitoring points. The planning of this platform is mainly to use Hikvision's EZVIZ cloud platform for access, so that the video data can be relatively stable, and the construction cost of the video platform is relatively low. Combined with other fire-fighting sensors, it can be monitored in the same large platform.

The electrical fire module 17 includes electrical fire detectors, fault arc detectors and current limiting protectors; electrical fire detectors should have the ability to detect leakage current, overcurrent and other signals, send out sound and light signal alarms, and accurately report the address of the faulty line , and cut off the power supply on the leakage circuit, and timely alarm to remind the staff to eliminate these hidden dangers; the residual current detector can not only alarm these hidden dangers, but also can slowly increase the heating temperature of the terminals or lines between the lines, or the leakage current is slow. Metallic short circuit or overload fault or grounding arc fault caused by the increase should be effectively prevented in advance, so as to better protect the safety of personnel and property.

In the process of circuit transmission, arcs will inevitably occur. Frequent occurrence of arcs will lead to overheating of wires and cause fires. Arc fault detectors are used to detect arcs in lines, find arcs and then alarm to avoid fires.

The fire alarm module 18 is the hardware that must be configured in the building, that is, the fire alarm controller, which is the heart of the automatic fire alarm system, can realize centralized control, can supply power to the detector, and has the function of receiving fire signals and starting the fire. Alarm device, can start fire alarm signal through fire alarm sending device or start automatic fire extinguishing equipment and fire linkage control equipment through automatic fire extinguishing control device, automatic monitoring system for correct operation and giving sound and light alarm for specific faults, etc. Discover all kinds of hidden faults in front-end fire protection facilities, and urge relevant departments to make rectifications to reduce fire risks. Traditional hosts can only provide local alarms. If they lack maintenance all the year round, and are generally deployed in professional places such as power distribution rooms and monitoring centers, special personnel are required to monitor and maintain them. Once a dangerous situation occurs, it is impossible for everyone to see the monitoring data in real time. And alarm information, some places are basically useless for a long time. After the alarm host data is integrated into the big platform, all owners can see the running status of the fire host configured in the building in real time, monitor the data in real time, and automatically get alerts such as SMS/APP push notifications when any danger occurs. Save the safety of people and property.

Once a real fire alarm occurs in a networked unit, the emergency lighting and evacuation instruction module 19 is activated, and the system determines the rescue method, rescue path, Rescue plans, etc., will display multi-dimensional data information such as fire alarm point unit information, location map coordinates, internal contacts, floor plans, internal danger sources and internal fire fighting resources. By checking the basic information of the enterprise, information on major danger sources, information on the surrounding environment of the enterprise, information on the enterprise's emergency rescue force and emergency plan, determine the rescue method, rescue path, rescue plan, etc. At the same time, the GIS system will display the fire extinguishing resources within a certain range outside the fire alarm point, the nearby major danger sources, etc., to provide auxiliary decision-making support for the operation. At the same time, the system sends alarm information to rescue forces such as the fire squadron, full-time fire brigade, and micro fire station closest to the fire alarm point, and conducts optimal path planning to launch firefighting and rescue operations.

The invention connects the scattered automatic fire alarm equipment, electrical fire monitoring equipment, fire alarm equipment, smart smoke detectors, smart fire fighting water, fire doors, fire fighting equipment power supply, emergency lighting and evacuation instructions to form a network, and provides a network for these devices. The status of the equipment is intelligently sensed, identified, and positioned, and fire-fighting information is dynamically collected in real time. Data analysis, mining and trend analysis are carried out through the cloud platform to help achieve scientific early warning of fire, grid management, and implementation of multi-responsibility supervision and other goals. It fills the gap that cannot be effectively monitored for "nine small places" and hazardous chemical production enterprises. It is suitable for all public and civil constructions, realizes unmanned duty smart firefighting, and realizes "automation" and "intelligence" of smart firefighting. , "systematization", and the actual needs of "refinement" of electricity management.

From fire prevention, to fire alarm, to control linkage, the present invention operates in a unified system platform, and users, security personnel, and supervisory units can intuitively see various types of fire-fighting equipment and equipment in each building through the platform. The operating status of the sensor, and in the case of emergency and non-emergency situations such as hidden dangers and fires, the relevant alarm and event information can be sent to you through SMS, voice calls, email reminders, and APP push within a few seconds. It is possible to quickly notify the relevant personnel of the arrival.

The above are only specific application examples of the present invention, and do not constitute any limitation to the protection scope of the present invention.
