Therefore, how to determine the positioning of people inside the fire scene and safely evacuate the trapped people when a fire occurs are the most concerned and difficult problems to solve in the fire fighting and rescue at present.
Currently, the main methods for positioning the people trapped in the fire image mainly include a system for positioning the people trapped in the fire based on a GPS monitoring system for remote image transmission, a system for positioning the people trapped in the fire based on fuzzy control, and a system for positioning the people trapped in the fire image based on an FPGA. Among them, the most commonly used is a system for locating people trapped in a fire based on a GPS monitoring system for remote image transmission. When personnel positioning is carried out by utilizing a traditional personnel positioning system trapped in a fire image, the personnel image collected by the video collecting equipment is greatly interfered by fire smoke, the panic walking degree of the trapped personnel and the panic walking of the trapped personnel, so that the personnel identification accuracy is reduced, and the positioning effect is poor.

Further, a ring of rubber rings 29 is provided between the cover plate 28 and the sieve plate 30.
Furthermore, two symmetrical contacts 32 are arranged on the splash plate 53, the contacts 32 are located on two sides of the push rod 31, and the contacts 32 are electrically connected with a far-end information transmission device through a lead.
Further, the heater 34 is an electrical heating structure and is electrically connected to the information transmission device at the remote end.
Further, a motor 37 is arranged below the outer side of the splash plate 53, the shaft of the motor 37 is connected with the lock pin 33 through a flexible shaft 52, and the motor 37 is electrically connected with a remote information transmission device.
The sprayer adopts an intelligent control sprayer, and comprises two sets of trigger devices, namely a traditional temperature passive trigger switch and an active opening device of an information transmission device. The traditional temperature passive trigger switch has the following working principle: when the ambient temperature rises to reach the fire alarm value, the thermal expansion material 35 in the lower cavity of the spray head senses high temperature and expands by heating, and the thermal expansion material extrudes upwards and pushes the push rod 31 to rise, pushes the clamping seat 56 and drives the cover plate 28 to move upwards together until the groove 54 on the push rod 31 is clamped into the lock pin 33 to stop. The clamping seat 56 and the cover plate 28 are fixedly connected through the ejector rod 55, and the lower end of the cover plate 28 is provided with the rubber ring 29 to ensure the sealing performance of the cover plate 28. Thus, when the clamp seat 56 is lifted up, the cover plate 28 is driven upwards, and water can be sprayed out from the sieve plate 30, so that fire can be extinguished.
When the information transmission device is actively started, the working principle of the device is as follows: when a fire disaster occurs, but the spray head is far away from the fire source, the thermal expansion material 35 in the cavity at the lower end of the spray head does not work due to thermal expansion, but the concentration values of the temperature and the smoke in the environment reach the early warning values set by the temperature sensor and the smoke sensor. The information transfer device will transmit the information to the heater 34 for heating, and the information transfer device will transmit the information to the central control, which will combine the data with the BIM to form a real-time fire cloud after receiving the information. The thermally expansible material 35 in the lower end chamber of the nozzle 22 is thermally expanded. The procedure is then the same as for the first principle.
The role of the two contacts 32 in fig. 2: when no fire occurs, the spray head is checked to detect whether water leaks or not when no fire occurs, if water is accumulated on the splash plate, the two contacts 32 are communicated, and then the power-on indication is carried out. When a fire disaster happens, the nozzles are judged to work actively or passively. When the sprayer works actively, two feedback signals are generated (one is a working signal sent by the information transmission device to the sprayer, and the other is a signal fed back to the information transmission device after the contact is triggered after the sprayer sprays water), so that only one working signal is generated when the sprayer works passively (after the sprayer sprays water, the signal fed back to the information transmission device after the contact is triggered). The motor 37 and the lock pin 33 are connected by a high-temperature-resistant nylon material, after the fire is extinguished, a command is issued by the central controller, the motor 37 drives the lock pin 33 to retract, and the push rod automatically falls down, so that the aim of repeated use is fulfilled. The position of the fire source is analyzed for the later period by analyzing the starting position and time of the first sprinkler of the sprinkler.
Furthermore, the water spraying fire extinguishing device adopts a traditional fire extinguishing pipeline, the spray head adopts an intelligent control spray head, and the spray head comprises two sets of trigger devices, namely a traditional temperature passive trigger switch and an active opening device of an information transmission device. The spray head trigger device can be repeatedly used, and the spray head water dispersion disc is provided with a contact to judge whether the spray head works normally. The triggering condition of the active triggering device is controlled by the temperature and smoke concentration data transmitted to the information transmission device by the personnel protection device. The active and passive start of the spray head returns different signals, and the signals are transmitted to the central control through the information transmission device.
Furthermore, the central control equipment is used for integrating data of the whole building, integrates data generated by internal sensors of the building and personnel protection devices, and combines the integrated data with BIM in real time to generate a building fire real-time monitoring cloud picture and a personnel positioning picture; the central control equipment judges the fire position through the integrated data, avoids dangerous positions through background data processing, plans an optimal route for shunting and evacuating, and transmits information to the information transmission device to assist people in the floor to evacuate to a safe position; the central control equipment transmits data to the rescue personnel equipment in real time by adopting an internet means. The rescue personnel can communicate with the trapped personnel through the background to assist in escaping.
Furthermore, the information transmission device is an important device for sending guide information, collecting and positioning personnel protection device data and controlling the work of the fireless device in the personnel escape process. The information transmission device comprises a data transmission receiving antenna (interacting with the helmet sensor integrated device), an emergency channel physical indication panel data processing and transmission processor and an internal emergency power supply.
Furthermore, the water spraying fire extinguishing device adopts a traditional fire extinguishing pipeline, the spray head adopts an intelligent control spray head, and the spray head comprises two sets of trigger devices, namely a traditional temperature passive trigger switch and an active opening device of an information transmission device.
