Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of fire monitoring devices, specifically relating to a titanium metal fire monitoring device based on a wireless network. Background Technology
[0002] Titanium metal itself has high corrosion resistance and strength, but its fire resistance is not particularly outstanding, especially at high temperatures. Titanium metal may oxidize when exposed to high temperatures, especially above 600°C. Therefore, fire monitoring is necessary when storing titanium metal. Existing fire monitoring devices, although equipped with built-in batteries, still consume battery power when the warehouse storing titanium metal experiences a power outage. The current practice is to replace the batteries (e.g., two new AA batteries) after each power outage and subsequent restoration to prevent the device from failing to supply power during subsequent power outages. Therefore, this invention proposes a titanium metal fire monitoring device based on a wireless network. Utility Model Content
[0003] The purpose of this invention is to provide a titanium metal fire monitoring device based on a wireless network, which can automatically charge the built-in battery when the battery voltage is low.
[0004] The specific technical solution adopted by this utility model is as follows:
[0005] A fire monitoring device for titanium metal based on a wireless network includes an explosion-proof housing base with an explosion-proof housing threaded onto it. A double-layer mounting plate is provided in the middle of the explosion-proof housing base. A circuit assembly is mounted on the upper layer of the double-layer mounting plate, and a temperature sensor probe and a smoke sensor probe are mounted on the lower layer of the double-layer mounting plate. The circuit assembly includes a circuit board and a battery mounted on the upper layer of the double-layer mounting plate. A control chip and a battery charging adapter are provided on the circuit board.
[0006] Preferably, the explosion-proof housing has four circular through holes in the middle, and the four circular through holes are respectively located on the side of the double-layer mounting plate.
[0007] Preferably, the circuit board is provided with a first voltage sensor and a second voltage sensor, the first voltage sensor being used to measure the total power line voltage and the second voltage sensor being used to measure the battery voltage.
[0008] Preferably, a speaker and a communication module are electrically connected to the circuit board, and both the speaker and the communication module are electrically connected to the control chip.
[0009] Preferably, the circuit board is provided with a data acquisition card, which is electrically connected to the temperature sensor probe, the smoke sensor probe, the first voltage sensor, and the second voltage sensor, and is also electrically connected to the control chip.
[0010] Preferably, the explosion-proof housing has an opening at the lower end, and a cover plate is connected to the lower end of the explosion-proof housing. Two through holes are provided on the cover plate, through which the temperature sensor probe and the smoke sensor probe pass respectively. A sealing ring is provided between the outer wall of the temperature sensor probe and the outer wall of the smoke sensor probe and the inner wall of the through hole.
[0011] The technical effects achieved by this utility model are as follows:
[0012] In this invention, when the first voltage sensor detects that the main power line voltage drops to 0V, it indicates a power outage. At this time, the control chip controls the switch at the battery discharge terminal, and the battery begins to supply power to the entire device. When the first voltage sensor detects that the main power line voltage rises again, it indicates that the main power line has resumed power supply. At this time, the control chip controls the switch at the battery discharge terminal to return to the open circuit. Then, the control chip controls the switch at the battery charging adapter terminal to open, completing the charging of the battery. During the charging process, the main power line simultaneously supplies power to the entire device, and the second voltage sensor is used to measure the battery voltage. When the battery voltage reaches the rated voltage, it indicates that the battery is fully charged. Then, the control chip controls the switch at the battery charging adapter terminal to open and continuously monitors whether there is any fire abnormality in the titanium metal. This invention can automatically charge the battery built into the fire monitoring device when it is undervoltage, thereby ensuring continuous monitoring effect. Attached Figure Description

[0022] Preferably, the explosion-proof housing 1 has four circular through holes in the middle, and the four circular through holes are located on the side of the double-layer mounting plate 3.
[0023] In this invention, the explosion-proof housing 1 is installed in the space near the titanium metal through four circular through holes and screws, and then the power is turned on.

At this time, the control chip 403 controls the switch of the discharge terminal of the battery 402, and the battery 402 begins to supply power to the entire device. When the first voltage sensor 406 detects that the total power line voltage rises again, it indicates that the total power line has resumed power supply. At this time, the control chip 403 controls the switch of the discharge terminal of the battery 402 to return to the open circuit. Then, the control chip 403 controls the switch of the battery charging adapter 405 to open, completing the charging of the battery 402. During the charging process, the total power line simultaneously supplies power to the entire device, and the second voltage sensor 407 is used to measure the voltage of the battery 402.

Figure 4 In order to make the circuit diagram clear, the first voltage sensor 406 and the second voltage sensor 407 are not drawn on the circuit board 401. In the actual product, the first voltage sensor 406 and the second voltage sensor 407 are installed on the circuit board 401 and are connected by specific circuits to monitor the voltage of the corresponding branch.
[0027] In this invention, the control chip 403 is an STM32 series microcontroller, the first voltage sensor 406 and the second voltage sensor 407 are ZMPT101B analog voltage sensors, and the switch at the discharge end of the battery 402 and the switch at the battery charging adapter 405 are relays or other switching elements that switch states according to the control signal output by the microcontroller.

In this embodiment, the control chip 403 is also connected to other circuits in order to complete its work. The specific circuit connection, data signal transmission and data signal processing of the control chip 403 are common knowledge and will not be described in detail here.

[0034] like Figures 1-4 As shown, the working principle of this utility model is as follows: When the first voltage sensor 406 detects that the total power line voltage drops to 0V, it indicates that the external power supply is interrupted. At this time, the control chip 403 controls the switch of the discharge terminal of the battery 402, and the battery 402 starts to supply power to the entire device. When the first voltage sensor 406 detects that the total power line voltage rises again, it indicates that the total power line has resumed power supply. At this time, the control chip 403 controls the switch of the discharge terminal of the battery 402 to return to the open circuit. Then, the control chip 403 controls the switch of the battery charging adapter 405 to open, completing the charging of the battery 402. During the charging process, the total power line simultaneously supplies power to the entire device, and the second voltage sensor 407 is used to measure the voltage of the battery 402. When the voltage of the battery 402 reaches the rated voltage, it indicates that the battery 402 is fully charged.
