Description

Technical Field

[0001] This utility model belongs to the technical field of protective reminders for gas extinguishing systems, specifically relating to a reminder device applied to protective measures for gas extinguishing systems. Background Technology

[0002] Gas fire suppression systems are widely used in important equipment rooms in subways. When a fire occurs in the equipment room, the gas fire suppression system is activated, spraying gas (such as heptafluoropropane or IG541) into the room to remove oxygen and extinguish the fire, reducing the damage to equipment and providing fire safety.

[0003] When performing routine maintenance on gas extinguishing systems, personnel must take protective measures to prevent the system from suddenly activating and spraying gas during maintenance, which could cause asphyxiation and lead to non-fire-related safety accidents. After maintenance is completed, personnel must remove all protective measures, ensuring they are properly removed. Inadequate removal can prevent the system from spraying gas in the event of a fire, potentially causing equipment damage and serious accidents.

[0004] Currently, the production department reminds workers to strictly adhere to safety procedures when maintaining and servicing gas fire suppression systems by posting safety reminders and notices in the gas cylinder room, thereby raising workers' safety awareness. In addition, the production department has implemented a manual review process for safety measures. When setting up safety measures for the gas fire suppression system, workers place the gas cylinder valve aside, take photos of the implemented measures and the safety reminder notices, and send these photos to an online information review group for further review. The same manual review process is applied when removing safety measures from the gas fire suppression system. However, the daily maintenance workload of the subway gas fire suppression system is substantial, and the manual review process results in low maintenance efficiency and high labor costs. Utility Model Content

[0005] To overcome one or more of the aforementioned technical defects, this utility model provides a reminder device for protective measures in gas extinguishing systems. This device monitors the placement of the cylinder valves in real time and provides audible and visual reminders, reducing operator error and preventing safety hazards caused by inadequate or improperly removed protective measures due to human factors. Furthermore, it addresses the problem of existing gas extinguishing system protective measures implementation or removal relying solely on manual review processes, saving labor costs for gas extinguishing system maintenance and improving operational efficiency.

[0006] To solve the above problems, this utility model is implemented according to the following technical solution:

[0007] A warning device for protective measures in gas extinguishing systems, comprising:

[0008] The detection module is installed next to the gas cylinder of the gas extinguishing system. It is used to detect the placement of the cylinder valve when setting up the protective measures of the gas extinguishing system, or when removing the protective measures of the gas extinguishing system.

[0010] An audio-visual prompt module, connected to the control module, is used to provide a first audio-visual prompt based on the prompt signal.

[0011] Furthermore, it also includes a mode switching module connected to the control module. The mode switching module includes a protection setting button and a protection removal button, which are used to switch different working modes of the control module. According to the switched working mode, the control module sends a corresponding working mode signal to the sound and light prompt module, and the sound and light prompt module provides a second sound and light prompt.

[0012] Furthermore, it also includes a touch screen display, which is connected to the control module via an RS422 serial port, and is used to display the placement status of the bottle head valve according to the prompt signals from the control module.

[0013] Furthermore, the detection module includes a metal induction sensor corresponding to the number of gas cylinders in the gas extinguishing system, used to collect information on the placement of the cylinder valves.

[0014] Furthermore, the audio-visual prompt module includes a voice unit and a prompt light unit, which are respectively connected to the control module via an RS485 serial port.

Detailed Implementation

[0022] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0023] Example 1

[0024] This embodiment discloses a warning device for protective measures in gas extinguishing systems, such as... Figure 1 and 2 It includes a detection module 100, a control module 200, an audio-visual prompt module 300, a mode switching module 400, and a touch screen 500. The audio-visual prompt module 300 includes a voice unit 310 and a prompt light unit 320.

[0025] Specifically, the mode switching module 400 is connected to the control module 200. The mode switching module 400 includes a protection setting button 410 and a protection removal button 420. According to the user's action, the control module 200 is switched to the protection setting mode or the protection removal mode. The control module 200 sends an entry signal to the sound and light prompt module 300 or an entry signal to the protection setting mode or the protection removal mode according to the switched working mode. The sound and light prompt module 300 provides sound and light prompts to indicate that the protection setting mode or the protection removal mode has been entered.

[0026] Specifically, the detection module 100 is installed next to the gas cylinders of the gas extinguishing system. The detection module 100 includes metal induction sensors 101 corresponding to the number of gas cylinders in the gas extinguishing system. The metal induction sensors 101 are used to collect information on the placement of the cylinder valves. When the user switches the control module to the protection setting mode via the protection setting button, the metal induction sensors detect whether a cylinder valve is placed. If so, they send a cylinder valve placement signal to the control module. When the user switches the control module to the protection removal mode via the protection removal button, the metal induction sensors detect whether the cylinder valve placed on it has been removed. If the cylinder valve has been removed, they send a cylinder valve removal signal to the control module. In this embodiment, 12 sets of metal induction sensors 101-1 to 101-12 are provided.

[0027] When the user switches the control module to protection setting mode via the protection setting button, the control module sends a protection setting prompt signal to the audible and visual prompt module based on the cylinder valve placement signal sent by the metal detection sensor. This prompts the audible and visual prompt module's voice unit to provide a voice prompt and the indicator light to flash red, reminding the user that protection measures for the gas fire extinguishing system are being set. Conversely, when the user switches the control module to protection removal mode via the protection removal button, the control module sends a protection removal prompt signal to the audible and visual prompt module based on the cylinder valve removal signal sent by the metal detection sensor. This prompts the audible and visual prompt module's voice unit to provide a voice prompt and the indicator light to flash green, reminding the user that protection measures for the gas fire extinguishing system are being removed.

[0028] In this embodiment, the voice unit 310 and the indicator light unit 320 are respectively connected to the control module 200 via RS485 serial ports.

[0029] Specifically, the touch display 500 is connected to the control module via an RS422 serial port. It is used to display whether the current protection setting mode or protection removal mode is displayed according to the prompt signal of the control module, and to display the placement or removal status of the bottle head valve.

[0030] Specifically, it also includes an AC24V power supply to provide power to the metal detection sensor, control module, voice unit, indicator light unit, and touch screen.

[0031] The following explanation is based on the specific implementation process:

[0032] When the gas extinguishing system requires maintenance, the operator sets up protective measures and presses the protection setting button to switch the control module to protection setting mode. The control module sends a signal to the audio-visual prompt module to enter protection setting mode, controlling the voice unit to issue a voice prompt: "Protection setting begins in the gas cylinder room of a certain station's mezzanine. xx sets remain." The indicator light unit flashes red to remind the user that protective measures for the gas extinguishing system are currently being set up. The operator places the disassembled gas extinguishing system cylinder valve onto the metal detection sensor. Each metal detection sensor sends a valve placement signal to the control module. Based on the received valve placement signals, the control module counts the number of disassembled gas extinguishing system cylinder valves in the room and issues a voice prompt: "yy sets remain" (the control module calculates the number of disassembled valves based on the signals from each metal detection sensor, which is existing technology and will not be elaborated here), and controls the indicator light unit to flash red. During the setup of protective measures, if the operation of a single cylinder valve takes more than 90 seconds, the control module sends a cylinder valve placement signal to the audio-visual prompt module. The audio-visual prompt module then provides a voice prompt: "Only yy sets remain," and controls the indicator light unit to flash red (the timing and judgment of the received signal by the control module is existing technology and will not be elaborated here). When all cylinder valves of the gas extinguishing system in the room are placed on the metal induction sensors, each metal induction sensor sends a cylinder valve placement signal to the control module. The control module considers the protective measures to be set up successfully, controls the voice unit to provide a voice prompt: "Protection has been set up in the gas cylinder room of a certain station's mezzanine," and controls the indicator light unit to flash red.

[0033] After the maintenance of the gas extinguishing system is completed, the operator removes the protective measures and presses the protection removal button to switch the control module to protection removal mode. The control module sends a signal to the audio-visual prompt module to enter protection removal mode, controlling the voice unit to issue a voice prompt: "In the gas cylinder room of a certain station, protection removal has begun. xx sets remain." The indicator light unit flashes green to remind the user that the gas extinguishing system protection measures are being removed. The operator removes and reinstalls the cylinder valves placed on the metal detectors onto the gas cylinders. Each metal detector sends a cylinder valve removal signal to the control module after sensing the removal of the cylinder valve. Based on the received cylinder valve removal signals, the control module calculates the current installation status of gas extinguishing system cylinder valves in the room, issues a voice prompt: "yy sets remain," and controls the indicator light unit to flash green. During the removal of protective measures, if the operation of a single cylinder valve takes more than 90 seconds, the control module sends a cylinder valve removal signal to the audio-visual prompt module again. The audio-visual prompt module then provides a voice prompt: "Only yy sets remain," and controls the indicator light unit to flash green. When all cylinder valves placed on the metal induction sensors are removed, each metal induction sensor sends a cylinder valve removal signal to the control module. The control module considers the removal of protective measures complete, controls the voice unit to provide a voice prompt: "Protection in the interlayer gas cylinder room of a certain station has been removed," and controls the indicator light unit to flash green.

[0034] The daily maintenance of subway gas fire suppression systems is substantial. Planned inspections and troubleshooting all involve ensuring the proper implementation of protective measures to guarantee the smooth operation of maintenance work. Conversely, the proper removal of these protective measures ensures the gas fire suppression system returns to normal operation, preventing any loss of its fire-fighting function. This invention provides a reminder device for protective measures in gas fire suppression systems. During the setting or removal of protective measures, a metal induction sensor detects the valve on the gas cylinder head to check if the protective measures are in place. The device then provides reminders to operators via voice, lights, and a display screen, standardizing the work process and providing real-time feedback on the operational status. This addresses the problem of existing gas fire suppression system protective measures relying solely on operator skills and safety awareness, and the complexity of the protective procedures. It saves manpower required for existing maintenance work, improves efficiency, reduces operator error, and avoids safety issues caused by human error leading to inadequate implementation or removal of protective measures.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
