Description

Technical Field

[0001] This application relates to the field of gas safety technology, and more specifically, to a gas pipeline voice emergency control device with electrostatic control linkage. Background Technology

[0002] In gas transmission and distribution scenarios, rapid emergency shutdown of pipeline leaks is crucial for ensuring personnel safety and equipment integrity. Meanwhile, static electricity remains a significant safety concern during personnel operations in gas leak environments. Existing technologies include the following static electricity control schemes for emergency shutdown operations in the event of a gas leak:

[0003] (1) Chinese invention patent CN116764143A discloses a safety production explosion-proof device, including an explosion-proof box. A fixed frame is fixedly connected to the bottom of the inner surface of the explosion-proof box. Electrical equipment is fixedly connected to the upper surface of the fixed frame. A protective device is fixedly connected inside the fixed frame. The outer surface of the protective device is fixedly connected to the bottom of the explosion-proof box. A ventilation baffle is fixedly connected to the inner wall of the explosion-proof box and is located directly above the electrical equipment. A switch door is rotatably connected to the front of the explosion-proof box. A control device is provided on the outer surface of the switch door. A temperature sensor is fixedly connected to the top of the inner surface of the explosion-proof box. A cooling device is fixedly connected to the top of the explosion-proof box. A spray pipe is fixedly connected to the outer surface of the explosion-proof box. The outer surface of the spray pipe penetrates the explosion-proof box and extends into the inner cavity. Fire extinguishing devices are fixedly connected to both sides of the explosion-proof box. A first guide rod is fixedly connected to the outer surface of the explosion-proof box. A first grounding rod is fixedly connected to the outer surface of the first guide rod. Water mist is sprayed into the interior of the explosion-proof box through the spray pipe to humidify it and reduce static electricity inside the explosion-proof box. The method of directly spraying the explosion-proof box does not effectively increase the humidity of the external environment, and on the other hand, it leads to excessive humidity inside the explosion-proof box, which poses a risk of short circuit.

[0004] (2) Chinese utility model patent with publication number CN215653412U discloses an anti-static device for a natural gas gasification station. This solution involves setting a door structure at the entrance of the natural gas gasification station, with a conductive plate and a conductive handle on the door to release static electricity when personnel push the door. A humidification structure is set on the upper part of the door to atomize the area outside the door. This solution is essentially a normalized humidification solution, which can control the ambient humidity. However, the normalized humidification environment has an impact on the long-term use of the equipment.

[0005] Therefore, there is still a need for a device that can safely shut off gas pipelines in a gas leak environment. Summary of the Invention

[0006] To address the aforementioned issues, this application adopts a gas pipeline voice emergency control device with electrostatic control linkage, comprising: a voice receiving module, an electrostatic control module, and a voice control module. The voice receiving module and the electrostatic control module constitute an electrostatic control linkage module. The voice receiving module includes a microphone, a voice recognition chip, and a wireless signal transmitter. The electrostatic control module includes a control chip, a hygrometer, a water tank, a shielded pump, and an atomizing nozzle. The water tank is connected to the inlet of the shielded pump via an inlet pipe, and the outlet of the shielded pump is connected to the atomizing nozzle via an outlet pipe. The voice control module includes a wireless signal receiver, a relay, a PLC control board, and a gas control solenoid valve. The voice receiving module, the electrostatic control module, and the voice control module are each powered by an independent battery.

[0007] Optionally, the control chip of the electrostatic control module receives humidity information from the hygrometer and signals from the voice receiving module. A water supply valve is installed between the water tank and the water inlet pipe. The start-up of the shielded pump and the opening and closing of the water supply valve are both controlled by the control chip of the electrostatic control module.

[0008] Optionally, the hygrometer is a mechanical hygrometer, which includes a mounting frame and a humidity-sensitive spring. The fixed end of the humidity-sensitive spring extends and is connected to a battery. The rotating end of the humidity-sensitive spring is connected to a rotating pointer based on a rotating shaft. The rotating pointer rests on a contact panel. The contact panel indicates a humidity range of 0-60% and is connected to the control chip through a first signal circuit. The contact panel indicates a humidity range of 60%-80% and is connected to the control chip through a second signal circuit. The humidity-sensitive spring and the rotating pointer are isolated by an insulating plate. The humidity-sensitive spring and the rotating pointer are provided with grease grooves at the positions where they pass through the insulating plate. The grease grooves are filled with sealing grease.

[0009] Optionally, the hygrometer is an electronic hygrometer, which includes a capacitive humidity sensor and a signal conversion circuit, wherein the capacitive humidity sensor is powered by an independent battery.

[0010] Optionally, the voice recognition chip includes, in the order of voice signal input, a microphone interface, a filter, an analog-to-digital converter, a digital signal processor, and a wireless signal transmitter interface. The voice recognition chip integrates RAM cache firmware and Flash storage firmware.

[0011] Optionally, the wireless signal transmitter includes a signal transmission control chip, an RF module, a power amplifier, and a transmitting antenna; the wireless signal receiver includes a receiving antenna, a low-noise amplifier, a filter, an RF module, and a signal receiving control chip.

[0012] Optionally, the electrostatic control linkage module is installed on the ceiling of the monitoring area at a height not exceeding 4m, the distance between the voice receiving modules does not exceed 5m, and the distance between the voice receiving module and the inner wall of the room in the monitoring area does not exceed 3m.

[0016] The beneficial effects of the electrostatic control linkage gas pipeline voice emergency control device provided in this application are as follows:

[0017] (1) After personnel identify that a gas leak has occurred, they can say the gas shut-off command. The voice receiving module receives the voice signal and transmits it to the voice control module based on the wireless signal. The voice control module controls the gas control solenoid valve to shut off the valve. Since the concentration of gas after a leak increases rapidly near the leak point, remotely controlling the gas shut-off can prevent personnel from entering areas with high gas concentrations and reduce the risk of suffocation or fire.

[0018] (2) After receiving the gas shut-off command in case of gas leakage, the electrostatic control module determines whether humidification needs to be turned on based on the air humidity to prevent the risk of static fire caused by low humidity, and at the same time prevent the risk of short circuit caused by high humidity. Each component is powered independently, and the electrical sealing performance is stronger compared with AC power supply. Attached Figure Description

Detailed Implementation

[0030] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0031] like Figure 1-3As shown, a gas pipeline voice emergency control device with electrostatic control linkage includes: a voice receiving module, an electrostatic control module, and a voice control module. The voice receiving module receives the operator's voice signal and transmits the control signal wirelessly. After receiving the signal, the voice control module shuts off the gas supply. The electrostatic control module provides air humidification when it receives the control signal from the voice receiving module and the humidity conditions are met, reducing the risk of electrostatic fire. In this embodiment, the electrostatic control module operates in an environment with a humidity of 0-80%. The voice receiving module and the electrostatic control module constitute an electrostatic control linkage module. The optimal placement standard for both the voice receiving module and the electrostatic control module prioritizes achieving maximum coverage with the fewest possible modules. Since the electrostatic control module needs to receive the signal provided by the voice receiving module, the voice receiving module and the electrostatic control module are integrated into an electrostatic control linkage module. The two sub-modules (voice receiving module and electrostatic control module) of each electrostatic control linkage module are integrated in the same location, which reduces the signal conversion requirements for wireless signal transmission and reduces the workload of installation and layout design.

[0032] The voice receiving module includes a microphone, a voice recognition chip, and a wireless signal transmitter. The microphone receives the operator's voice signal, and the voice recognition chip identifies specific commands. In this embodiment, the control commands include "stop," "emergency stop," "rapid emergency stop," and "rapid stop." Recognizing multiple commands increases system robustness and improves recognition accuracy while avoiding misrecognition. After recognizing the control command, the voice recognition chip transmits it to the control chip 6 of the electrostatic control module, which is a necessary condition for the operation of the electrostatic control module. Simultaneously, the voice recognition chip transmits the control command to the wireless signal transmitter, sending control signals to the voice control module.

[0033] The electrostatic control module includes a control chip 6, a hygrometer, a water tank 1, a shielded pump 2, and an atomizing nozzle 5. The water tank 1 is connected to the inlet of the shielded pump 2 via an inlet pipe 3, and the outlet of the shielded pump 2 is connected to the atomizing nozzle 5 via an outlet pipe 4. After receiving the signal from the voice recognition chip, the control chip 6 of the electrostatic control module determines whether to start the humidification operation based on the value of the hygrometer. Water is supplied to the shielded pump 2 through the water tank 1 via the inlet pipe 3. After the shielded pump 2 starts, it pressurizes the water and delivers it to the atomizing nozzle 5 via the outlet pipe 4 for high-pressure spray humidification. High-pressure spray humidification has better sealing and less heat dissipation than dry steam humidification, electrode humidification, and ultrasonic humidification. At the same time, the shielded pump 2 further seals the motor from the outside air. In the design provided in this application, the minimum openings of the electrostatic control module are (1) the hygrometer detection position; (2) the atomizing nozzle 5; and (3) the water inlet of the water tank 1. In a more radical design, water tank 1 can be a pre-installed, closed water tank. However, this design requires a pressure balancing port for water tank 1, thus making it essentially no different from a water tank 1 with a water inlet. With a water inlet, the water tank 1, inlet pipe 3, water flow channel of the shielded pump 2, outlet pipe 4, and atomizing nozzle 5 inside the electrostatic control module are sequentially connected and isolated from the circuitry of the electrostatic control module, thereby achieving better explosion-proof performance. In this embodiment, water tank 1 is positioned above the shielded pump 2, which meets the medium-driven start-up requirements of the shielded pump 2 without requiring additional power for water supply.

[0034] The voice control module includes a wireless signal receiver, relays, a PLC control board, and a gas control solenoid valve. The wireless signal receiver receives control commands from the wireless transmitter of the voice receiving module, demodulates the signal, and extracts the command content (e.g., 0x01 = Close gas valve). After receiving the command, the PLC control board executes preset logic, closing the gas control valve and triggering the alarm indicator. The relay contacts connect the power supply to the gas control solenoid valve, and the relay auxiliary contacts return the status to the PLC control board, confirming the completion of the action.

[0035] As a single-instruction circuit, the received verified signal can be regarded as closing the gas valve, and no instruction is extracted.

[0036] like Figure 9 As shown, as a feasible alternative, the voice receiving module only performs analog-to-digital conversion on the sound signal before transmitting it. The voice control module parses the voice signal, and the wireless receiving module 25 transmits the instruction information to the voice control board 24. The voice control board 24 begins to identify whether it is an instruction of "stop", "emergency stop", "rapid emergency stop" or "rapid stop". If so, the SONGLE relay 23 in the voice control module closes, transmitting a signal to the PLC control board and the relay, thereby closing the gas control solenoid valve.

[0037] The voice receiving module, electrostatic control module, and voice control module are each powered by independent batteries, such as... Figures 2-3 As shown, the electrostatic control module is equipped with a battery 9, which provides independent power and achieves the effect of a closed circuit design. Powered by an independent battery, the minimum openings required for the electrostatic control linkage gas pipeline voice emergency control device provided in this application are: (1) the hygrometer detection position; (2) the atomizing nozzle 5; and (3) the water inlet of the water tank 1. That is, all the openings of the electrostatic control module. In actual use, the microphone of the voice receiving module usually needs an additional opening to receive sound signals, but this opening is not mandatory.

[0038] When the gas pipeline voice emergency control device with electrostatic control linkage has only a minimum opening, and the water flow channels of water tank 1, water inlet pipe 3, shielded pump 2, water outlet pipe 4, and atomizing nozzle 5 are filled with water, the only opening that may affect the explosion-proof performance is the hygrometer detection position. The explosion-proof design of this position is provided in subsequent embodiments.

[0039] It should be noted that the "explosion-proof" effect provided by the technical solution of this application is not a replacement for the "Electrical Apparatus for Explosive Atmospheres" series of standards (GB 3836), but a further optimized design based on the suitability of electrical apparatus for explosive atmospheres. Simply implementing or satisfying the technical features provided in this application should not be regarded as completing the design that meets the explosion-proof standard. Figures 2-9 The wiring connection structure is not shown. Figures 2-3 The casing of the electrostatic control module and the water inlet of the water tank are not shown.

[0040] In another embodiment of this application, such as Figure 1-3 As shown, the control chip 6 of the electrostatic control module receives humidity information from the hygrometer and signals from the voice receiving module. A water supply valve 8 is installed between the water tank 1 and the water inlet pipe 3. The start-up of the shielded pump 2 and the opening and closing of the water supply valve 8 are both controlled by the control chip 6 of the electrostatic control module. Compared with the unified control of voice recognition and humidification based on the electrostatic control linkage module, the control chip 6 of the electrostatic control module can independently shut down the entire circuit of the electrostatic control module after humidification is completed, and power is cut off after humidification is completed. This can further reduce the risk of fire without affecting the voice receiving module. In this embodiment, before receiving the voice signal, the blades of the shielded pump 2 are in a waterless state.

[0041] In another embodiment of this application, such as Figure 4-8As shown, the hygrometer is a mechanical hygrometer 7, which includes a mounting frame 10 and a humidity-sensitive spring 11. A battery is connected to the fixed end 13 of the humidity-sensitive spring, and a rotating pointer 14 is connected to the rotating end 12 of the spring based on a rotating shaft 21. The rotating pointer 14 rests on a contact panel. The contact panel indicates a humidity range of 0-60%, which is connected to the control chip 6 via a first signal circuit 15. In the figure, this area is represented as the first humidity region 16. The control panel indicates a humidity range of 60%-80%, which is connected to the control chip 6 via a second signal circuit 17. In the figure, this area is represented as the second humidity region 18. An insulating region 20 is provided between the first humidity region 16 and the second humidity region 18. The humidity-sensitive spring 11 and the rotating pointer 14 are isolated by an insulating plate 19. "Isolation" means that there is an insulating plate 19 in between. In reality, a rotating shaft 21 connects the humidity-sensitive spring 11 and the rotating pointer 14. A grease groove 22 is provided at the point where the humidity-sensitive spring 11 and the rotating pointer 14 pass through the insulating plate 19. The grease groove 22 is filled with sealing grease, which provides a seal on the inside and outside of the insulating plate 19, preventing leaked gas from entering the rotating pointer 14. In the illustration, there is a relatively large gap around the rotating shaft 21. This gap is to demonstrate the movement performance of the rotating shaft 21. In actual use, this gap should be minimized as much as possible while ensuring that the rotating shaft 21 can sensitively detect the rotation of the humidity-sensitive spring 11, in order to prevent grease leakage. If the grease consistency is too high, it will affect the humidity feedback; if the consistency is too low, it will easily leak. This application uses No. 1 lithium-based grease conforming to GB / T 7324-2010.

[0042] One end of the humidity-sensitive reed 11 is fixed to the mounting bracket 10, and the other end is connected to the rotating shaft 21. The material of the humidity-sensitive reed 11 of the mechanical hygrometer 7 is the same as that commonly used in the prior art for the humidity-sensitive reed 11 of mechanical hygrometers 7. In the prior art, the body of the humidity-sensitive reed 11 is usually made of a metal main material and a coating of hydrophilic humidity-sensitive polymer material. In this application, the humidity-sensitive reed 11 uses brass as the main material, and one side in the width direction is covered with a polyimide coating. The first signal circuit 15 and the second signal circuit 17 provide different currents by setting different resistance values. When the voice receiving module receives the signal, the control chip 6 of the electrostatic control module connects the first signal circuit 15 and the second signal circuit 17 to identify the magnitude of the current, thereby determining the output power of the shielded pump 2. When the received current signal comes from the first signal circuit 15, full power output humidification spray is used. When the received current signal comes from the second signal circuit 17, 1 / 2 to 2 / 3 power output humidification spray is used to prevent excessive humidity from affecting the reliability of other circuits in the environment.

[0043] In another embodiment of this application, the hygrometer is an electronic hygrometer, which includes a capacitive humidity sensor and a signal conversion circuit. The capacitive humidity sensor is powered by an independent battery. Compared to a mechanical hygrometer 7, the capacitive humidity sensor has a faster response speed, more accurate readings, and can control humidity more efficiently. However, it requires an additional signal conversion circuit for signal amplification, filtering, and analog-to-digital conversion. The solution in this application does not require humidity measurement beyond specific thresholds (60%, 80%). Therefore, in practical use, the type of hygrometer can be selected based on cost control and requirements.

[0044] In another embodiment of this application, the speech recognition chip includes, in sequence according to the input order of the speech signal, a microphone interface, a filter, an analog-to-digital converter (ADC), a digital signal processor (DSP), and a wireless signal transmitter interface. The speech recognition chip integrates RAM cache firmware and Flash storage firmware. The microphone interface receives microphone input, the filter suppresses high-frequency noise to improve speech recognition performance, and the ADC converts the analog signal into a digital signal that the DSP can recognize. The sampling rate of the ADC needs to meet the speech bandwidth requirements. The Flash storage firmware permanently stores the acoustic model, firmware code, and keyword library, while the RAM cache firmware temporarily stores real-time audio data and intermediate calculation results for audio data feature extraction.

[0045] In another embodiment of this application, the wireless signal transmitter includes a signal transmitting main control chip, an RF module, a power amplifier, and a transmitting antenna; the wireless signal receiver includes a receiving antenna, a low-noise amplifier, a filter, an RF module, and a signal receiving main control chip. The transmitting main control chip receives voice recognition signals from the wireless signal transmitter interface. The transmitting main control chip is also used for encoding instructions, controlling the communication protocol, and performing power management. The main control chip encapsulates the instructions into data frames, which are then modulated by the RF module. The carrier power is set, and the signal is amplified by the power amplifier and radiated by the transmitting antenna. The receiving antenna captures the signal, amplifies it by the low-noise amplifier, filters it, demodulates it by the RF module, extracts the data frames, and transmits them to the signal receiving main control chip.

[0046] In another embodiment of this application, the electrostatic control linkage module is installed on the ceiling of the monitoring area at a height not exceeding 4m. The installation height refers to the height of the electrostatic control linkage module from the ground. The distance between voice receiving modules does not exceed 5m, and the distance between the voice receiving module and the inner wall of the room in the monitoring area does not exceed 3m. In this embodiment, "inner wall" includes the corner formed between walls. Room corners are considered inner walls; therefore, for corner locations, in the planar direction, the distance between the voice receiving module and the vertex of the corner of the room must not exceed 3m.

[0047] In another embodiment of this application, the ratio of the number of electrostatic control linkage modules to the volume of the monitored area is 1: 50-100m². 3 The set quantity is rounded up to the nearest integer. Background noise in quiet residential areas is typically in the range of 30-40 decibels, while normal human speech is around 60 decibels. For redundancy, the sound signal received by the electrostatic control linkage module must be no less than 50 decibels. Based on sound intensity attenuation, the receiving radius of the electrostatic control linkage module is designed to be 3.16m, covering an area of ​​31.4m². 2 In a room with a ceiling height of 3 meters, each electrostatic control linkage module covers a space of 94.2m². 3 Considering the actual height of people, the minimum sparse arrangement of electrostatic control linkage modules is required to be every 100m. 3 One is placed within the space.

[0048] In another embodiment of this application, the ratio of water tank volume to monitoring area volume is 1L:50-70m³. 3 The water tank's capacity should be sufficient to raise the humidity in the space from 0% to 80%. Assuming an indoor temperature of 20°C, a saturation pressure of water vapor in the air of 0.0023366 MPa, and a relative humidity of 80%, each cubic meter of air contains 0.0142 kg of water vapor. The minimum water tank volume ratio should be 1L:70m³. 3 .

[0049] In another embodiment of this application, such as Figure 1 As shown, the voice control module includes an alarm indicator light, which uses an LED indicator light with a wavelength of 620-750nm. To provide optimal visible light penetration, this embodiment uses an LED indicator light with a wavelength of 620-750nm to provide a red alarm indication. Compared to other colors of visible light, red light has a longer wavelength, is less affected by Rayleigh scattering, and has strong penetrating power.

[0050] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application, and should all be included within the protection scope of this application.
