[0002] The existing intelligent fire extinguishing warning system stores liquid or gaseous fire extinguishing agents in tanks, which are then connected to the space to be protected through pipes. Temperature sensors or smoke sensors are then installed in the space to monitor fires, and the fire is extinguished by controlling the release of fire extinguishing agents on the chip. Not only is the structure complex and occupies a large area, but it is also overly dependent on electronic devices such as sensors, which are prone to risks such as false alarms and missed alarms, as well as failure to extinguish fires in a timely manner due to sensor damage. At the same time, electronic devices such as sensors rely on power supply, and once the power supply is out of power, the system will be paralyzed. Summary of the invention

[0006] When a fire occurs, the thermoelectric power generation module is heated to generate current to power the control component. The control component converts and stores the electrical parameters generated by the thermoelectric power generation module and sends them to the terminal through the communication module. The terminal determines the fire intensity based on the received electrical parameters and issues an alarm based on the fire intensity. At the same time, when the fire temperature reaches the excitation temperature of the fire extinguishing microcapsules, the fire extinguishing microcapsules rupture and release the fire extinguishing agent.

[0009] Furthermore, the temperature difference power generation module includes a P-type semiconductor arranged on the top of the intelligent fire extinguishing warning module and an N-type semiconductor at the bottom. The N-type semiconductor is provided with a through hole for the fire extinguishing microgel to pass through.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Embodiment 1:

[0032] Reference Figure 1-2 , an intelligent fire extinguishing warning system, including a terminal 1 and a plurality of intelligent fire extinguishing warning modules 2 set under the terminal 1.

[0033] The intelligent fire extinguishing warning module 2 comprises a circular ring-shaped housing 3 , in which a fire extinguishing microcapsule 4 , a control component 5 and a temperature difference power generation module 6 are arranged.

[0034] The temperature difference power generation module 6 includes a P-type semiconductor 61 arranged on the top of the shell 3 and an N-type semiconductor 62 at the bottom. The P-type semiconductor 61 and the N-type semiconductor 62 form a cavity with the shell 3. The N-type semiconductor 62 is provided with a plurality of through holes 63, and a hot melt adhesive 64 that melts when heated is provided in the through holes 63. The hot melt adhesive 64 has a thermal melting temperature of 95°C. The fire extinguishing microcapsule 4 and the control component 5 are arranged in the cavity.

[0035] The fire extinguishing microcapsule 4 includes a shell and a fire extinguishing agent arranged inside the shell. The shell is made of a polymer or a composite material, and the fire extinguishing agent is a perfluorohexanone fire extinguishing agent or other fluorine-based fire extinguishing agents. When the perfluorohexanone fire extinguishing agent is heated, it will gasify, expand, and burst the shell to release the perfluorohexanone fire extinguishing agent into the space where the fire started, thereby extinguishing the flame. The rupture temperature of the fire extinguishing microcapsule shell is 100°C.

[0036] A control chip 51 and a communication module 52 are provided in the control component 5. The P-type semiconductor 61 and the N-type semiconductor 62 form a loop with the control component 5 through wires. The control chip 51 is used to control the conversion of electrical parameters and the transmission of data, etc. The communication module 52 is a WIFI communication module or a 4G, 5G communication module.

[0037] When a fire occurs, the N-type semiconductor 62 of the thermoelectric power generation module 6 is heated, and when the temperature difference between the N-type semiconductor 62 and the P-type semiconductor 61 is greater than 40°C, a current is generated to supply power to the control component 5. After the control component 5 is powered on, the electrical parameters generated by the thermoelectric power generation module 6 are converted and stored and sent to the terminal 1 through the communication module 51. At the same time, when the fire temperature reaches the excitation temperature of the fire extinguishing microcapsule 4, the fire extinguishing microcapsule 4 ruptures and releases the fire extinguishing agent.

[0038] The installation position of each intelligent fire extinguishing module 2 is displayed on the interface of terminal 1. Terminal 1 determines the fire intensity by receiving the electrical parameters (voltage and current) of each intelligent fire extinguishing module 2, and issues an alarm according to the fire intensity (the voltage and current generated under different temperature differences generally increase with the increase of temperature difference, and the size of temperature difference is calculated by the change of electrical parameters). For example, when the temperature difference is 40℃-70℃, the yellow light flashes and a short warning sound is sounded; when the temperature difference is 70℃-100℃, the red light flashes and a short warning sound is sounded; when the temperature difference is greater than 100℃, the red light flashes and a rapid warning sound is sounded. At the same time, when the temperature difference is 40℃-70℃ for more than 45s, the flashing of the yellow light turns to the flashing of the red light, and when the continuous maintenance time is more than 60s, the warning sound changes from short to rapid; when the temperature difference is 70℃-100℃ for more than 30s, the warning sound changes from short to rapid. The flashing light can be an external warning light, or the icon and / or outer ring of the interface corresponding to the intelligent fire extinguishing module 2 can change color and flash. At the same time, after receiving the information of the intelligent fire extinguishing module 2, the terminal 1 sends the alarm information to the reserved mobile phone number via SMS.

[0039] Furthermore, the longitudinal cross section of the housing 3 is arc-shaped. The arc-shaped structure can accommodate more fire-extinguishing microcapsules 4 under the housing 3 with a shorter width.

[0040] Furthermore, the fire extinguishing microcapsule 4 is fixed in the space enclosed by the housing 3 and the P-type semiconductor 61 and the N-type semiconductor 62 by means of a flame retardant hot melt adhesive, and the melting temperature of the flame retardant hot melt adhesive is 95°C.

[0041] Embodiment 2:

[0042] like Figure 3-6 An intelligent fire extinguishing warning system includes a terminal 1 and a plurality of relay base stations 11 set under the terminal 1, and a plurality of intelligent fire extinguishing warning modules 2 are set under the relay base stations 11. The main interface of the terminal 1 displays the status of each relay base station 11, and the status of each intelligent fire extinguishing warning module 2 under the relay base station can be viewed by clicking on each relay base station. The status of each intelligent fire extinguishing warning module can also be viewed on the relay base station 11.

[0043] The intelligent fire extinguishing warning module 2 comprises a shell 3 with a rectangular cross-section, in which a fire extinguishing microcapsule 4, a control component 5, a temperature difference power generation module 6 and a detection module 7 are arranged.

[0044] The thermoelectric power generation module 6 includes a P-type semiconductor 61 disposed on the top of the shell and an N-type semiconductor 62 disposed on the bottom, and the P-type semiconductor 61 and the N-type semiconductor 62 form a cavity with the shell 3. The N-type semiconductor 62 is in the shape of a rectangular ring, with a through hole in the middle for releasing the fire extinguishing microcapsule 4.

[0045] The fire extinguishing microcapsule 4 includes a shell and a fire extinguishing agent arranged inside the shell. The shell is made of a polymer or a composite material, and the fire extinguishing agent is a perfluorohexanone fire extinguishing agent or other fluorine-based fire extinguishing agents. When the perfluorohexanone fire extinguishing agent is heated, it will gasify, expand, and burst the shell to release the perfluorohexanone fire extinguishing agent into the space where the fire started, thereby extinguishing the flame. The rupture temperature of the fire extinguishing microcapsule shell is 110°C.

[0046] The fire extinguishing microcapsule 4 is fixed to one side of the detection module 7 by glue. The detection module 7 in this embodiment is a gravity sensing module. The gravity sensing module is electrically connected to the control component 5. The gravity sensing module is fixed below the P-type semiconductor 61, and one side of the fire extinguishing microcapsule 4 faces the N-type semiconductor 62. The fire extinguishing microcapsule 4 of a certain weight is fixed on the gravity sensing module to record the initial weight data. When the fire extinguishing microcapsule is released, the weight on the gravity sensing module is reduced. The gravity sensing module transmits the reduced weight data to the control chip 51 and sends it to the relay base station 11 through the communication module 52. The relay base station 11 synchronously transmits the data to the terminal 1. The communication module 52 is a WIFI communication module or a 4G, 5G communication module.

[0047] The control component 5 is arranged between the gravity sensing module and the P-type semiconductor 61. The control chip 51 and the communication module 52 are arranged in the control component 5. The control chip 51 is used to control the conversion of the conversion electrical parameters, the transmission of data, and the reception and transmission of the weight data of the fire extinguishing microcapsules. The shell 3 is embedded with a conductive sheet 31. The two ends of the conductive sheet 31 are provided with contact joints 32 that penetrate the shell 3 and conduct with the P-type semiconductor 61 and the N-type semiconductor 62. The P-type semiconductor 61 and the N-type semiconductor 62 are connected to the control chip 51 of the control component 5 through wires to form a closed loop.

[0048] When a fire occurs, the N-type semiconductor 62 of the thermoelectric power generation module 6 is heated, and when the temperature difference between the N-type semiconductor 62 and the P-type semiconductor 61 is greater than 40°C, a current is generated to supply power to the control component 5. After the control component 5 is powered on, the electrical parameters generated by the thermoelectric power generation module 6 are converted and stored and sent to the relay base station 11 through the communication module 51, and the relay base station 11 synchronously transmits the data to the terminal 1. At the same time, when the fire temperature reaches the excitation release temperature of the fire extinguishing microcapsule 4, the fire extinguishing microcapsule 4 ruptures to release the fire extinguishing agent, and the control component 5 receives the weight data of the fire extinguishing microcapsule fed back by the gravity sensing module, and synchronously transmits the weight data of the fire extinguishing microcapsule to the relay base station 11, and the relay base station 11 synchronously transmits the data to the terminal 1.

[0049] The relay base station 11 and the terminal 1 judge the fire intensity by receiving the electrical parameters and weight data of the fire extinguishing microcapsules of each intelligent fire extinguishing module 2, and issue an alarm according to the fire intensity. For example, when the temperature difference is 40℃-70℃, the yellow light flashes, and the fire extinguishing microcapsules are generally not stimulated and released in this temperature difference section (calculated according to the temperature of 20-30℃ at room temperature of P-type semiconductor); when the temperature difference is 70℃-100℃, the red light flashes and a short warning sound sounds, and the fire extinguishing microcapsules in this temperature difference section begin to release fire extinguishing and cooling; when the temperature difference is greater than 100℃, the red light flashes and a rapid warning sound sounds. At the same time, when the weight data of the fire extinguishing microcapsule drops to 0, the temperature difference is still rising or not falling, then the red light flashes directly and a rapid warning sound sounds. When the weight of the fire extinguishing microcapsule 4 is reduced by half, it reminds you to replace the temperature difference power generation module 6. The flashing light can be an external warning light, or it can be the icon of the interface corresponding to the intelligent fire extinguishing module 2 and / or the outer ring of the interface to change color and flash. It is understandable that the light color can be changed according to personal choice. At the same time, the terminal 1 and the relay base station 11 send the alarm information to the reserved mobile phone number via SMS after receiving the information of the intelligent fire extinguishing module 2.

[0050] Furthermore, the conductive sheet 31 covers the entire interior of the housing 3, and the contact connector 32 is ring-shaped and fully conductively connected to the P-type semiconductor 61 and the N-type semiconductor 62. By providing the full-contact conductive sheet 31, the connection between the P-type semiconductor 61 and the N-type semiconductor 62 is further ensured, the electron transfer speed of the P-type semiconductor 61 and the N-type semiconductor 62 is improved, and a current with a larger voltage can be generated at a lower temperature, so as to better and timely supply power to the control component 5.

[0051] Furthermore, the surface of the N-type semiconductor 62 is coated with a heat absorption layer, which can accelerate the temperature rise of the N-type semiconductor 62; the surface of the P-type semiconductor 61 is coated with a heat insulation layer, which can maintain the low temperature state of the P-type semiconductor 61. The provision of the heat absorption layer and the heat insulation layer further accelerates the power-on time of the control component 5, providing further protection for the discovery and handling of fire accidents.

[0052] Furthermore, the relay base station 11 can be connected to multiple relay base stations 11 to form a multi-level intelligent fire extinguishing system network, which is convenient for different levels to check the status of the subordinate intelligent fire extinguishing warning modules and handle the subordinate fire accidents.

[0053] Furthermore, the fire extinguishing microcapsules 4 are fixed on the gravity sensing module by means of flame retardant hot melt adhesive, and the melting temperature of the flame retardant hot melt adhesive is 100°C.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
