As a kind of special robot, fire-fighting robots play an increasingly important role in firefighting and rescue. A large number of large-scale petrochemical enterprises, tunnels, subways, etc. are increasing, and hidden dangers such as leakage of oil gas, toxic gas, explosion of tunnels, and subways are increasing. Fire-fighting robots can replace the fire and rescue personnel to collect, process, and feed back data from hazardous accidents such as flammable, explosive, toxic, oxygen-deficient, and heavy smoke. In 2012, Virginia Polytechnic designed a CHARLI-2 fire-fighting robot for the US Navy. This robot can jump into popular “Gangnam Style” dance and become popular on YouTube.

At present, a newly developed “variable frequency variable variable variable-capacity Fire Phoenix hydraulic fire extinguishing robot” with variable frequency is very much concerned by customers in the fire protection industry. It implements a control terminal that can simultaneously control 8 robots within 3 kilometers. Not only is it lightweight and convenient, it is suitable for all kinds of small-scale daily dangerous fire accidents, but it is also particularly suitable for such large-scale and extra large-scale fire accidents as the Big Bang of Tianjin. It has many advantages. At the same time, this robot company is also the only firefighting robot company invited by the Ministry of Science and Technology to participate in the "2015 China (Mianyang) International Military Exhibition", and is also representing the State Intellectual Property Office "2014 China International High-tech Achievement Exhibition "The only fire fighting robot.

Fire Robot - Advantages and Weaknesses

advantage

1, no life injury. As a non-living carrier, fire fighting robots can fully exert their functions in areas where manpower is out of reach in the face of various dangerous and complicated environments such as high temperature, poisonous, oxygen-deficient and dense smoke, greatly reducing the number of casualties of firefighters. If equipped with fire-fighting robots, the tragedy of the Huangdao oil depot and “11.3” Hunan Hengyang fire could have been avoided.

2, reusability. Fire-fighting robots, as a special type of weaponry, can be used repeatedly and exert their effectiveness while being carefully maintained.

3, artificial intelligence. Modern robots are a combination of high-end disciplines such as artificial intelligence, neural networks, computer technology, automatic control, power electronics, fuzzy control, and mechanical industries. As a kind of special robot, the fire fighting robot is a combination of high-tech achievements. The robot has been one of the signs that reflects the country's technological advancement. The technical departments of the governments of various countries and companies face the increasingly complex emergency rescue environment for fire fighters. Under the premise of mature artificial intelligence, other high and new technologies are combined to develop targeted fire fighting robots for special situations. According to the actual situation on the spot, it can autonomously determine the sources of actual dangers, and conduct data collection, processing, transmission feedback, fire extinguishing and other work.

Shortcomings

1, maintenance is complicated. As firefighting robots are a combination of high technology and new technology, there are certain requirements for the control and maintenance personnel, and professional knowledge requires certain knowledge. Professional training must be held on a regular basis, especially electronic components, or it may be exposed to moisture, smoke, and dust. Such influences require a certain knowledge base for maintenance.

2, high cost. Because firefighting robots belong to a collection of advanced subject knowledge and advanced advanced technologies, the development time is long, research and development expenses are high, and the number of production is not large, resulting in generally expensive prices, and can not be equipped with a large number of fire brigades. At the same time, the unbalanced economic development in various regions and the limited ability of the government to allocate funds are also one of the important reasons why it cannot provide large numbers of fire-fighting troops.

Fire Robot - Rescue Effect

(a) mobile function. In the category of fire robots, it has been stated that crawlers or wheels can be used according to the local conditions. From the actual situation of disaster accidents, the mobile robots of fire fighting robots must have strong off-road capability and certain self-adaptability. Judging and crossing obstacles on their own, autonomously analyzing the situation on the spot, and completing the complicated functions such as climbing stairs at a certain angle.

(b) Detection function. Fire-fighting robots can rely on various electronic components for detection according to the site conditions of a disaster accident. The loading of the camera can transmit the situation on site to the rear system through the communication network in real time, and it depends on various sensors. There are two main types: one is an internal sensor, which is used to detect the status parameters of the fire robot itself in the disaster accident site, fed back to the central brain DSP, make reasonable path planning, and arrange the fire robot according to the disaster accident site conditions. Orderly work. The other is an external sensor used to detect various data (disaster conditions, fire temperature, radiant heat intensity, toxic gas or flammable gas type and concentration, and oxygen content, etc.) at the disaster site, providing raw data for the rear processing system. .

(c) Control and processing communication functions. Because DSP has unmatched advantages compared with SCM in processing digital information, fire-fighting robots generally use DSP as information processing brain. The control processing communication is mainly composed of three aspects: First, the fire robot internal processing system. Through various sensors to detect actual disaster site data, DSP analyzes and processes the original data. The second is the communications network. The public security firefighting force's own three-level network can be used for data transmission. Considering the maturity of the technology, the public can use the 2.5G GPRS (General Packet Radio Service) or the 2.75G EDGE (Enhanced Data Rate for GSM Evolution) network. Wuxi has taken the lead in implementing 3G network communications. Therefore, after the technology becomes more mature, it can directly use 3G networks to carry out remote wireless data communications, and can implement duplex or even multiplex communication; another method is wire control. What is worth noting is that under the conditions of complex disaster accidents, no matter what kind of communication method is used, it will cause poor communication and it needs urgent solution. Based on the self-adapting fire-fighting robots, it is imperative to develop and introduce self-adaptive fire-fighting robots according to the disaster accident site situation, self-judgment and decision-making. The third is the rear auxiliary decision system. Afterwards, the situation in front of the accident scene is known through data communication, providing first-hand information for the on-site commander and supplemented by an expert decision-making system to assist the on-site commander in making reasonable and correct judgments.

(4) Anti-corrosion and explosion-proof functions. It is precisely because fire fighting robots take the place of firefighters to enter the scene of dangerous and complex disaster accidents. It is necessary to take into consideration the ability of their electronic components, mechanical materials, and other structures to withstand the harsh environment of corrosion, high temperature, dust, and heavy smoke, and to protect their key parts against corrosion. Anti-explosion treatment ensures that it is in a stable working condition to ensure the successful completion of the task.

(E) Fire protection function. This is also the main function of the fire robot. Through preliminary preparations for fire fighting robots, the on-site commander provides information according to the rear auxiliary decision system, and based on his personal experience in extinguishing and rescue, he makes correct judgments, issues remote command, and instructs the fire robot to perform on-site disposal.
