The spray head 22 adopts an intelligent control spray head, and the spray head 22 comprises two sets of trigger devices, namely a traditional temperature passive trigger switch and an active opening device of an information receiving transmission device. The working principle of the traditional temperature passive trigger switch is as follows: the temperature of the surrounding environment rises to reach the fire warning value, the thermal expansion material 35 in the cavity at the lower end of the spray head senses high temperature and expands when heated, the push rod 31 is extruded upwards and pushed to rise, the push rod pushes against the clamping seat 56 and drives the cover plate 28 to move upwards together, and the cover plate stops when the groove 54 on the push rod 31 is clamped into the lock pin 33.

The working principle of the device when the information transmission device is actively started is as follows: when a fire has occurred, but because the sprinkler head 22 is located farther from the fire source, the thermal expansion material 35 in the lower cavity of the sprinkler head 22 does not expand thermally, but the temperature and smoke concentration values in the environment reach the pre-alarm values set by the temperature sensor and the smoke sensor. The information transmission device will transmit the information to the heater 34 for heating, and the information transmission device will also transmit the information to the central control, and after receiving the information, the central control combines the data with the BIM to form a real-time fire cloud image. The thermal expansion material 35 in the lower chamber of the spray head 22 expands by heating. Then as in the first principle.

Further, the sprinkler fire extinguishing device adopts a traditional fire extinguishing pipeline, the spray head 22 adopts an intelligent control spray head, and the spray head 22 comprises two sets of trigger devices, namely a traditional temperature passive trigger switch and an active opening device of an information receiving transmission device. The trigger device of the spray head 22 is reusable, and the water dispersion disc of the spray head 22 is provided with a contact electrode 32 to judge whether the spray head 22 works normally. The triggering conditions of the active triggering device are controlled by the temperature 19 and smoke concentration data transmitted by the personnel protection device into the information transmission device. The active and passive actuation of the spray head 22 will return different signals which are transmitted to the central control through the information transmission device.
Further, when the sprinkler 22 is passively protected, the sensor detects the occurrence of a fire, the thermal expansion material 35 expands due to heat, the lower push rod 31 is pushed upwards, the upper push rod 31 drives the cover plate 28 to move upwards until the concave of the push rod 31 is clamped into the lock pin 33, and water flow is sprayed out from the sieve plate 30 to extinguish the fire.
Further, while the sprinkler head 22 is actively protecting, the sensor does not detect the occurrence of a fire, but personnel have found the occurrence of a fire. The central controller transmits signals to the heater 34 for heating, the thermal expansion material 35 is heated and expanded, the lower push rod 31 is pushed upwards, the upper push rod 31 drives the cover plate 28 to move upwards until the concave part of the push rod 31 is clamped into the lock pin 33, and water flow is sprayed out of the sieve plate 30 for fire extinguishment.
Further, after the fire extinguishing of the spray head 22 is finished, the main sluice is closed, the lock pin 33 is driven by the motor to retreat, and the push rod 31 drives the cover plate 28 to fall back onto the sieve plate 30, so that the aim of recycling is fulfilled.
The system has simple structure and easy operation, can infer the position of fire on site by the concentration of toxic and harmful substances, and can actively extinguish the fire, position personnel and plan escape routes. The spray head device realizes the recycling, adopts the active/passive starting, realizes the starting and closing of each spray head through the sensor, and achieves good use effect in a starting mode.
