Abstract
Description
Technical Field
[0001] This utility model relates to the field of downhole self-rescue equipment technology, specifically, it is an infrared communication self-rescue device and a self-rescue device storage cabinet. Background Technology
[0002] Self-rescue devices are essential respiratory protective equipment worn by underground workers. They effectively protect the oxygen supply during safe evacuation from toxic or harmful gas pollution and oxygen deficiency hazards, serving as the last line of defense for their lives. Each self-rescue device contains an oxygen cylinder with an oxygen pressure gauge. Currently, the safety status of self-rescue devices can only be monitored manually. Users or managers observe the position of the oxygen pressure gauge pointer through the viewing window to determine if the oxygen level is adequate. This method is susceptible to human error, cannot guarantee real-time monitoring accuracy, and is time-consuming, error-prone, and lacks automation. Utility Model Content
[0003] The purpose of this utility model is to provide an infrared communication self-rescue device and a self-rescue device storage cabinet to solve the problem that the existing technology of relying on manual observation of the oxygen pressure gauge pointer position is not intuitive enough, cannot avoid human error, and cannot fully guarantee the safety of miners' oxygen use in emergencies.
[0004] The present invention solves the above problems through the following technical solution:
[0005] An infrared communication self-rescue device includes an MCU microprocessor (also known as a single-chip microcomputer), wherein the MCU microprocessor is connected to a first infrared communication module, a display module, an oxygen pressure gauge, and a power supply module.
[0006] Furthermore, the first infrared communication module includes an infrared emitting diode (IRF) and an infrared receiving diode (IRS). The first end of the infrared emitting diode (IRF) is connected to an I / O port (input / output pin of the MCU microprocessor). The second end of the infrared emitting diode (IRF) is connected to the first end of resistor R7. The second end of resistor R7 is connected to the power supply module. The second end of resistor R7 is also connected to the first end of resistor R8 and the first end of resistor R10. The second end of resistor R10 is connected to the first end of the infrared receiving diode (IRS) and the positive input terminal of the operational amplifier. The second end of resistor R8 is connected to the inverting input terminal of the operational amplifier, the first end of capacitor C14, and the first end of resistor R9. The operational amplifier is connected to another I / O port of the MCU microprocessor. The second ends of capacitor C14, resistor R9, and the second end of the infrared receiving diode (IRS) are grounded.
[0007] Furthermore, the display module includes an LCD screen driver chip electrically connected to the MCU microprocessor and a liquid crystal display electrically connected to the LCD screen driver chip.
[0008] Furthermore, the LCD screen driver chip is powered by the power module.
[0009] Furthermore, the oxygen pressure gauge has a circuit board installed inside, on which the display module, the first infrared communication module, and the power supply module are integrated.
[0010] An infrared communication self-rescue device storage cabinet includes a self-rescue device storage cabinet MCU microprocessor and a second infrared communication module. The second infrared communication module communicates with a first infrared communication module in the infrared communication self-rescue device and is electrically connected to the self-rescue device storage cabinet MCU microprocessor. The self-rescue device storage cabinet MCU microprocessor is connected to an external computer for communication.
[0011] Compared with the prior art, this utility model has the following advantages and beneficial effects:
[0012] (1) This utility model provides a self-rescue device with digital display and infrared communication functions. It can transmit the internal temperature, oxygen pressure value, and ID code data of the self-rescue device to a computer through infrared communication between the self-rescue device and the self-rescue device storage cabinet, realizing remote automatic data reading and monitoring, and thus screening out self-rescue devices with air leaks, low air pressure, high air pressure, and abnormal temperature. It can also compare and analyze the data stored in the database corresponding to the same ID code number in the computer to determine whether the self-rescue device has exceeded its service life and whether its quality is under control. It saves the time of manual screening, avoids the probability of errors in manual screening, and improves management efficiency and safety management level.
[0013] (2) Since self-rescue devices are stored and managed in a dense manner, there may be hundreds or even thousands of self-rescue devices in a single room. If communication is carried out using electromagnetic wave methods such as WIFI and Bluetooth, numerous WIFI and Bluetooth signals will interfere with each other and cause interference from numerous electromagnetic wave reflections in the same environment, as well as limitations in coverage. Reliability and stability are difficult to guarantee, and the cost is also very high. This utility model adopts infrared communication. Compared with communication methods such as WIFI and Bluetooth, infrared communication is a directional short-range communication. Each self-rescue device communicates with its own storage cabinet door and its own storage cabinet. There is no interference between self-rescue devices or self-rescue device storage cabinets, resulting in high reliability, good stability, and low cost.
[0014] (3) This utility model installs a circuit board inside the dial of the oxygen pressure gauge. The circuit board integrates digital display function and infrared communication function. Compared with the single pointer pressure gauge in the prior art, it realizes a multi-functional oxygen pressure gauge. The structure is more compact. Attached Figure Description

Detailed Implementation
[0023] The present invention will be further described in detail below with reference to the embodiments, but the implementation of the present invention is not limited thereto.
[0024] Example 1:
[0025] Combined with appendix Figure 1 As shown, an infrared communication self-rescue device 1 includes an MCU microprocessor IC1, which is connected to a first infrared communication module, a display module, an oxygen pressure gauge 12, and a power supply module.
[0026] The data from the oxygen pressure gauge 12 is transmitted to the MCU microprocessor IC1. The MCU microprocessor IC1 displays the data intuitively through the display module and transmits it to the self-rescue device storage cabinet 2 through the first infrared communication module, so that the self-rescue device storage cabinet 2 can interact with the computer for remote viewing, monitoring and automatic analysis.
[0027] This invention provides a self-rescue device with digital display and infrared communication functions. It can intuitively obtain oxygen pressure values. The MCU microprocessor IC1 can also connect to sensors such as temperature sensors. Through infrared communication between the self-rescue device and its storage cabinet, data such as temperature, oxygen pressure, and ID code can be transmitted to a computer. This enables remote data reading and monitoring, allowing for the detection of self-rescue devices with leaks, low pressure, or high pressure. This saves time on manual screening, reduces the probability of errors in manual screening, and improves management efficiency and level.
[0028] Because self-rescue devices are densely packed—a single room may contain hundreds or even thousands—Wi-Fi and Bluetooth signals suffer from interference and attenuation, as well as coverage limitations. This invention employs infrared communication, which, compared to Wi-Fi and Bluetooth, eliminates interference between self-rescue devices, and is also low-cost and highly reliable.
[0029] The data includes temperature, oxygen pressure, and ID code. The ID code includes, but is not limited to, the name, model, manufacturer, supplier, quantity, safety mark number, production date, product serial number, expiration date, arrival date, acceptance date, acceptance contents and results, etc.
[0030] Furthermore, such as Figure 2 As shown, the first infrared communication module includes an infrared emitting diode (IRF) and an infrared receiving diode (IRS). The first end of the infrared emitting diode (IRF) is connected to one I / O port of the MCU microprocessor IC1. The second end of the infrared emitting diode (IRF) is connected to the first end of resistor R7. The second end of resistor R7 is connected to the power supply module (which provides a 3.3V operating voltage). The second end of resistor R7 is also connected to the first ends of resistor R8 and resistor R10. The second end of resistor R10 is connected to the first end of the infrared receiving diode (IRS) and the positive input terminal of operational amplifier IC4. The second end of resistor R8 is connected to the inverting input terminal of operational amplifier IC4, the first end of capacitor C14, and the first end of resistor R9. Operational amplifier IC4 is connected to another I / O port of the MCU microprocessor IC1. The second ends of capacitor C14, resistor R9, and the second end of infrared receiving diode (IRS) are grounded.
[0031] Furthermore, such as Figure 2 As shown, the display module includes an LCD screen driver chip IC2 electrically connected to the MCU microprocessor IC1 and a liquid crystal display IC3 electrically connected to the LCD screen driver chip IC2.
[0032] Optionally, the MCU microprocessor IC1 uses an APM32 series microcontroller; the LCD screen driver chip IC2 uses a TM1621E; and the liquid crystal display IC3 uses an LCD-3X8.
[0033] Furthermore, the LCD screen driver chip IC2 is powered by the power module.
[0034] Furthermore, the power module is battery 123.
[0035] Example 2:
[0036] Based on Example 1, combined with Figure 5 , Figure 6 and Figure 7 As shown, a circuit board 122 is installed inside the dial 121 of the oxygen pressure gauge 12. The circuit board 122 integrates the display module, the first infrared communication module, and the power supply module. Specifically, the circuit board 122 has a liquid crystal display IC3 that can display the oxygen pressure value of the self-rescuer in real time, an infrared emitter IRF, and an infrared receiver IRS. The self-rescuer 1 is equipped with an oxygen pressure gauge observation window 11, through which the oxygen pressure value on the display screen can be directly read.
[0037] This invention features a circuit board 122 installed inside the dial of the oxygen pressure gauge 12. The circuit board 122 integrates digital display and infrared communication functions, achieving a multi-functional oxygen pressure gauge compared to the single pointer-type pressure gauges in the prior art. It also boasts a more compact structure.
[0038] Example 3:
[0039] Combination Figure 3 and Figure 4 As shown, an infrared communication self-rescue device storage cabinet includes a self-rescue device storage cabinet MCU microprocessor and a second infrared communication module 21. The second infrared communication module 21 communicates with the infrared emitting tube (IRF) and infrared receiving tube (IRS) in the infrared communication self-rescue device and is electrically connected to the self-rescue device storage cabinet MCU microprocessor. The self-rescue device storage cabinet MCU microprocessor is connected to an external computer for communication.
