Description

Technical Field

[0001] This utility model relates to an intrinsically safe emergency stop loudspeaker telephone for mining, belonging to the field of communication equipment technology. Background Technology

[0002] Currently, mining communication equipment faces many challenges, including ensuring reliable communication in harsh underground environments, rapid response to emergency stops, and effective communication with miners in emergencies. Traditional mining communication equipment may not be designed to meet these specific needs or may lack comprehensive functionality, failing to simultaneously provide emergency stop capabilities and clear audio communication. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide an intrinsically safe emergency stop loudspeaker telephone for mining. It can provide a rapid emergency stop function in emergency situations and achieve clear audio communication to cooperate with the overall operation of the mine system, ensuring stable operation in harsh environments and improving the safety and reliability of internal mine communication.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: an intrinsically safe emergency stop loudspeaker telephone for mining, comprising:

[0005] A housing, wherein a working cavity is provided in the housing;

[0006] A communication component, comprising a speaker, a microphone, and an audio processing circuit board, wherein the speaker and the microphone are disposed on the surface of the housing, the audio processing circuit board is mounted in the working cavity, and the speaker and the microphone are electrically connected to the main controller of the audio processing circuit board respectively;

[0007] An emergency stop locking mechanism includes an emergency stop component and two operating levers disposed through the housing, and a locking control circuit board installed in the working chamber. The emergency stop component and the two operating levers are electrically connected to the locking control circuit board, which is electrically connected to external mining equipment.

[0008] Furthermore, to ensure timely information transmission and response, the audio processing circuit board integrates a digital noise reduction module and an audio forwarding module. The digital noise reduction module is electrically connected to the microphone, and the audio forwarding module is electrically connected to the audio forwarding modules of the speaker and other related devices.

[0009] Furthermore, a mining intrinsically safe emergency stop loudspeaker telephone also includes a button assembly, which includes a dot button and a talk button, both of which are mounted on the housing;

[0010] The dot button and the talk button are electrically connected to the main controller via signal transmission lines;

[0011] Pressing the dot button allows the main controller to send a dot signal to the main controller of other associated devices via the audio forwarding module, causing the speaker of the other device to play a ringing sound.

[0012] When the speaker button is pressed, the main controller controls the microphone to enter the voice acquisition state, processes the acquired signal in real time through the digital noise reduction module, and simultaneously controls the audio forwarding module to send the processed voice signal to the speakers of other associated devices.

[0013] Furthermore, to prevent accidental operation, the surface of the housing is provided with an anti-accidental touch flange. The anti-accidental touch flange surrounds the pressing end of the dot button and the talk button, and the height of the anti-accidental touch flange exceeds the button trigger stroke by 3-5mm.

[0014] Furthermore, in order to improve the stability of the equipment and extend its service life, ventilation mesh grooves are provided on both sides of the housing, and dust filters are embedded in the ventilation mesh grooves.

[0015] Furthermore, a mining intrinsically safe emergency stop loudspeaker telephone also includes a power socket, which is embedded in the side of the housing and is adapted to provide power to the interlocking control circuit board and the main controller via a connecting cable.

[0016] By adopting the above technical solution, this utility model has the following beneficial effects:

[0017] 1. In this utility model, when the device is in standby mode, it is continuously powered by an external power socket, and the main controller maintains real-time monitoring of the audio processing circuit board and the interlocking control circuit board.

[0018] When an emergency occurs and the equipment needs to be stopped, the operator pulls the operating levers on both sides at the same time. The mechanical linkage device drives the emergency stop component to generate displacement and trigger the limit switch. After receiving the trigger signal, the interlocking control circuit board sends an interlocking signal to the mine control system through hard wiring. The mine control system immediately cuts off the power supply to the associated equipment.

[0019] A short press of the dot button generates a dot signal in the main controller. The audio forwarding module sends the dot signal to the main controller of the associated device via the bus. The main controller of the associated device then emits an audio signal and plays a preset alarm sound through the speaker.

[0020] If the button is pressed for more than 0.5 seconds, the main controller will activate the microphone to collect audio. The digital noise reduction module will filter background noise in real time. The processed voice signal will be encoded by the audio forwarding module and sent to the main controller of the associated device. The speaker of the associated device will then play the clear voice synchronously.

[0021] 2. In this utility model, there are multiple devices in the entire mine system. To complete the emergency stop of a system, multiple emergency stop devices are required to perform the emergency stop operation. However, it is difficult to get back to the operation in the mine by simply using a wireless telephone. By using the loudspeaker on the emergency stop device to notify the surrounding operators to arrive at the emergency stop device, timely communication and emergency stop can be carried out.

[0026] To make the content of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0027] like Figure 1-4 As shown, a mine-use intrinsically safe emergency stop public address telephone includes:

[0028] Housing 1, with a working cavity 11 inside;

[0029] The communication component includes a speaker 21, a microphone 22 and an audio processing circuit board 23. The speaker 21 and the microphone 22 are disposed on the surface of the housing 1, and the audio processing circuit board 23 is installed in the working cavity 11. The speaker 21 and the microphone 22 are electrically connected to the main controller of the audio processing circuit board 23 respectively.

[0030] The emergency stop locking mechanism includes an emergency stop component 31 and two operating levers 32 that are installed through the housing 1, and a locking control circuit board 33 installed in the working chamber 11. The emergency stop component 31 and the two operating levers 32 are electrically connected to the locking control circuit board 33, and the locking control circuit board 33 is electrically connected to external mining equipment.

[0031] In this embodiment, the main controller is an MCU, which is integrated on the audio processing circuit board 23;

[0032] The emergency stop locking mechanism is existing technology, and its implementation principle and detailed mechanism will not be described in detail in this embodiment.

[0033] Specifically, such as Figure 4 As shown, the audio processing circuit board 23 integrates a digital noise reduction module 231 and an audio forwarding module 232. The digital noise reduction module 231 is electrically connected to the microphone 22, and the audio forwarding module 232 is electrically connected to the speaker 21 and the audio forwarding modules 232 of other related devices.

[0034] Specifically, such as Figure 1-3 As shown, a mining intrinsically safe emergency stop loudspeaker telephone also includes a button assembly, which includes a dot button 41 and a talk button 42, both of which are mounted on the housing 1.

[0035] The dot button 41 and the talk button 42 are electrically connected to the main controller via signal transmission lines;

[0036] Pressing the dot button 41 allows the main controller to send a dot signal to the main controller of other associated devices via the audio forwarding module 232, causing the speaker 21 of another device to play a ringing sound.

[0037] Pressing the talk button 42 activates the microphone 22 to enter voice acquisition mode. The main controller then processes the acquired signal in real time through the digital noise reduction module 231 and simultaneously controls the audio forwarding module 232 to send the processed voice signal to the speaker 21 of other related devices.

[0038] Specifically, such as Figure 1 As shown, the surface of the housing 1 is provided with an anti-accidental touch flange 12, which surrounds and encloses the pressing ends of the dot button 41 and the talk button 42, and the height of the anti-accidental touch flange 12 exceeds the button trigger stroke by 3-5mm.

[0039] Specifically, such as Figure 1-3 As shown, ventilation mesh grooves 13 are also provided on both sides of the housing 1, and dust filters are embedded in the ventilation mesh grooves 13.

[0040] In this embodiment, the ventilation mesh 13 improves heat dissipation efficiency, effectively balances the air pressure inside and outside the equipment, and at the same time blocks common mine environment particles such as coal dust and rock powder from entering the working chamber 11 through the dust filter.

[0041] Specifically, such as Figure 1-4 As shown, a mine-use intrinsically safe emergency stop loudspeaker telephone also includes a power socket 14, which is embedded in the side of the housing 1 and is adapted to provide power to the interlocking control circuit board 33 and the main controller via a connecting cable.

[0042] In this embodiment, when the device is in standby mode, it is continuously powered by the external power socket 14, and the main controller maintains real-time monitoring of the audio processing circuit board 23 and the latching control circuit board 33.

[0043] When an emergency occurs and the equipment needs to be stopped, the operator pulls the operating levers 32 on both sides at the same time. The mechanical linkage device drives the emergency stop component 31 to generate displacement and trigger the limit switch. After receiving the trigger signal, the interlocking control circuit board 33 sends an interlocking signal to the mine control system through hard wiring. The mine control system immediately cuts off the power supply to the associated equipment.

[0044] When the dot button 41 is pressed briefly, the main controller generates a dot signal. The audio forwarding module 232 sends the dot signal to the main controller of the associated device via the bus. The main controller of the associated device emits an audio signal and plays a preset alarm sound through the speaker 21.

[0045] Press and hold the talk button 42 for more than 0.5 seconds, the main controller will activate the microphone 22 to collect audio, the digital noise reduction module 231 will filter background noise in real time, the processed voice signal will be encoded by the audio forwarding module 232, and the voice signal will be sent to the main controller of the associated device through the audio forwarding module 232, and the speaker 21 of the associated device will play clear voice synchronously.

[0046] The entire mine system has multiple pieces of equipment. To complete an emergency stop of a system, multiple emergency stop devices are needed to perform the emergency stop operation. However, it is difficult to get back to the scene in the mine using only wireless telephones. By using the loudspeaker on the emergency stop device to notify the surrounding operators to arrive at the emergency stop device, timely communication and emergency stop can be carried out.

[0047] The specific embodiments described above further illustrate the technical problems, technical solutions, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
