Description

Technical Field

[0001] The utility model relates to the technical field of voice reminders, in particular to a novel voice reminder for checking the positions of a gas fire extinguishing device and a fire door. Background Art

[0002] The equipment rooms of each station in the rail transit industry are equipped with fire-fighting devices such as FAS systems and gas extinguishing systems. The gas extinguishing devices must be operated accordingly when entering and exiting the equipment room to ensure that the gas extinguishing devices are in an accurate and effective state and to ensure the safety of personnel and equipment. However, in actual use, personnel often forget to operate the gas extinguishing devices, which brings great safety hazards. For example, after entering the equipment room, if the gas extinguishing system is not placed in the "manual" position in advance, once a fire occurs in the room, the gas extinguishing device will immediately release mixed gas to quickly reduce the oxygen concentration in the air, and personnel may suffocate and endanger their lives; for example, after leaving the equipment room, the gas extinguishing system is not placed in the "automatic" position in time. Once a fire occurs in the room, the gas extinguishing system will not be able to automatically release gas, resulting in the inability to control the fire in time. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] In order to solve the technical problem that personnel often forget to operate the gas extinguishing device when entering and leaving the equipment room, which brings great safety hazards, please refer to Figure 1-6 , providing the following technical solutions:

[0025] In this embodiment, a new voice reminder for checking the position of a gas fire extinguishing device and a fire door includes a main control device, a main control device housing 1, a voice module 5, a magnetic induction module 6 and a light sensing module 7. The main control device and the voice module 5 are both located inside the main control device housing 1. The main control device is composed of a control chip 2, a power module 4 and a button 3. The control chip 2 uses a chip with model STC15W402AS. The magnetic induction module 6 is composed of a Hall element and a magnet 8. The voice module 5 is composed of a voice chip and a speaker. The voice chip uses a chip with model WTN6170. The dip switch of the voice chip uses a dip switch with model SW-DIP4 for controlling the volume. The speaker uses a volume control chip with model WT1312.

[0026] The power module 4 is any one of a removable battery and an external power supply. The output voltage of the power module 4 is 5v. The power module 4 adopts a step-down chip of model Ams1117-3.3v, which can reduce 5v to 3.3v and realize the step-down function well.

[0027] The magnetic induction module 6 is installed on the door frame of the machine room. The magnetic induction module 6 is electrically connected to the control chip 2. The magnet 8 of the magnetic induction module 6 is installed on the door. The magnetic induction module 6 is used to detect the open and close state of the door.

[0028] The light sensing module 7 is installed on the gas extinguishing indicator sign, and the light sensing module 7 is electrically connected to the control chip 2. The gas extinguishing indicator sign is provided with indicator lights that can be turned on and off automatically and indicator lights that can be turned on and off manually. The light sensing module 7 is divided into an automatic light sensing module 7 and a manual light sensing module 7. The automatic light sensing module 7 is located on the indicator light that can be turned on and off automatically, and the manual light sensing module 7 is located on the indicator light that can be turned on and off manually. The light sensing module 7 is used to detect whether the light of the indicator sign is on or off.

[0029] The output end of the button 3 is electrically connected to the input end of the control chip 2, the output end of the power module 4 is electrically connected to the input end of the control chip 2, and the output end of the control chip 2 is electrically connected to the input end of the voice module 5. The control chip 2 can decide whether to issue a prompt sound based on the two conditions of "the switch status of the door" and "the lighting of the gas extinguishing sign". The button 3 is used to manually control the pause of the prompt sound of the speaker of the voice module 5.

[0030] Working principle: When in use, the gas fire extinguishing operation box used to control the gas extinguishing system is installed next to the door of the equipment room. When people enter and exit the door, the magnetic induction module 6 transmits the signal of the detected door switch status to the control chip 2. At the same time, the light sensing module 7 transmits the signal of the detected light status of the gas extinguishing indicator sign to the control chip 2. The control chip 2 processes the two conditions of "door switch status" and "gas extinguishing indicator sign on and off" and sends a voice prompt instruction to the voice module 5. The personnel operate the gas extinguishing device in manual or automatic position or open / close the door on the gas fire extinguishing operation box according to the prompt voice, and finally turn off the prompt sound by pressing button 3.

[0031] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
