[0023] To make the objectives and advantages of this invention clearer, the invention will be specifically described below with reference to embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of the invention and does not strictly limit the scope of protection specifically claimed by the invention.
[0024] like Figure 1 As shown, a fire extinguishing system suitable for quadruped robots includes a fire extinguishing robot and a control system. The fire extinguishing robot includes a quadruped robot 1. The quadruped robot 1 is provided with a double-layer mounting frame 2 on its upper part. The first layer of the double-layer mounting frame 2 is equipped with an industrial control computer 3, an edge computer 4, and a voltage regulator 5. The second layer of the double-layer mounting frame 2 is equipped with a DC power supply 6, a switch 7, a positioning camera 8, and a fire extinguisher 9. A support frame 10 is also installed at the end of the second layer of the double-layer mounting frame 2. A lidar 11 is provided on the upper end of the support frame 10. A binocular depth camera 12 is installed on the upper side of the support frame 10.
[0025] Preferably, a display screen 13 is fixedly installed on the fire extinguisher 9, and a first pipe 14 is connected to the outlet end of the fire extinguisher 9. The end of the first pipe 14 passes through the partition of the double-layer mounting frame 2 and is connected to the voltage stabilizer 5. The output end of the voltage stabilizer 5 is connected to a nozzle 15.
[0026] Preferably, a first fixing ring 16 is fixedly connected to the double-layer mounting frame 2, the nozzle 15 passes through the first fixing ring 16, an electric first telescopic rod 17 is provided on the side of the double-layer mounting frame 2, an electric second telescopic rod 18 is provided at the output end of the electric first telescopic rod 17, a collar 19 is connected to the output end of the electric second telescopic rod 18, and the collar 19 is fitted on the nozzle 15; the electric first telescopic rod 17 and the electric second telescopic rod 18 are perpendicular to each other, and the collar 19 is located on one side of the first fixing ring 16.
[0027] Preferably, the industrial control computer 3 is used to calculate the control algorithm and communicates with the edge computer 4.
[0028] Preferably, the binocular depth camera 12 identifies the fire source at the fire scene through the edge computer 4, and the edge computer 4 adjusts the angle of the nozzle 15 according to the location of the fire source through the electric first telescopic rod 17 and the electric second telescopic rod 18.
[0029] In practical use, the edge computer 4 adjusts the position of the collar 19 by driving the output end of the first electric telescopic rod 17 to slide laterally or by driving the output end of the second electric telescopic rod 18 to slide laterally. This, in conjunction with the first fixed ring 16, changes the angle of the nozzle 15, thereby adjusting the angle of the extinguishing agent and achieving high-precision fire extinguishing. Specifically, this is achieved by processing and locating the fire source image to adjust the extinguishing angle.
[0030] Preferably, the lidar 11 performs mapping and positioning through the edge computer 4.
[0031] Preferably, the positioning camera 8 performs calculations through the industrial control computer 3 to obtain the global positioning of the quadruped robot 1.
[0032] The working principle of this invention is as follows: This firefighting quadruped robot 1 is modified from a conventional quadruped robot 1, and its structural diagrams in all directions are shown below.

A detailed structural framework diagram is shown below. Figure 3 As shown.
[0033] Its perception system consists of a binocular depth camera 12, a lidar 11, and a T265 positioning camera 8. This system is primarily responsible for identifying and locating the fire scene. The binocular depth camera 12 acquires depth information of the environment, aiding the firefighting quadruped robot 1 in accurate environmental perception and fire source location. The lidar 11 measures the distance and speed of surrounding objects, assisting the firefighting quadruped robot 1 in environmental modeling and obstacle avoidance. The T265 positioning camera 8 is used for the precise positioning and navigation of the firefighting quadruped robot 1, including visual odometry and simultaneous localization and mapping (SLAM) functions. These three components work together to transmit the acquired fire scene map information to the edge computer 4 and the upper-level controller, which then integrate the information. In summary, the main task of the perception system is to identify and locate the fire scene.
[0034] The communication system consists of a PC terminal and a switch 7. Operators can remotely monitor and control the fire-fighting quadruped robot 1 via a computer. The robot 1 can also connect different controllers and computing units internally via a local area network. All internal and external components rely on the internal UDP communication protocol of the switch 7 to ensure reliable data transmission.
[0035] The software system of this firefighting quadruped robot 1 consists of numerous functional modules, including fire source detection, fire source localization, autonomous navigation, image transmission 13, path planning, communication protocols, SLAM, and sensor configuration. This module contains a large number of sensors, which play a crucial role in the operation of the firefighting quadruped robot 1. Only after the software system identifies and maps the fire scene through the sensors can it send commands to the controller, thereby controlling the hardware system.
[0036] In addition to the joint motor device of the conventional quadruped robot 1, the fire-fighting robot is equipped with an additional fire extinguisher 9 control device.
