Description

Technical Field

[0001] The present invention relates to a mine video broadcasting system and a working method, belonging to the technical field of coal mine operation communication. Background Art

[0002] In the mining industry, underground working environments are complex and dangerous. With technological advancements, the demand for video surveillance and broadcasting systems within mines is increasing. Traditional mine communication equipment is limited in functionality and struggles to operate reliably in such environments. Therefore, a system capable of efficient and secure video broadcasting and information transmission is needed to ensure effective communication between the surface dispatch room and underground workers. A search revealed that Chinese patent publication number CN102592629B discloses an intrinsically safe network voice controller for mining. In this patent, upon system startup, the CPU initializes each module through an embedded operating system, scans audio files from an SD card, and generates a playlist. During normal operation, the controller loops through the playlist contents, maintaining a network connection with the host computer via heartbeat packets and synchronizing IP / MAC address information. Upon receiving a broadcast command or audio file transfer request from the host computer, the controller pauses the current playback, prioritizes processing the network audio stream, and decodes and outputs it in real time. Once the task is completed, the original playback resumes, thereby providing safety education and emergency response services to underground workers. However, the patent system only supports audio broadcasting and lacks video information transmission and real-time display capabilities. When the equipment is interrupted or fails, it only relies on heartbeat packets to maintain the connection. There is a lack of specific maintenance mechanisms, and fault handling relies on manual troubleshooting, which easily delays the time for emergency repairs. Summary of the Invention

[0028] Furthermore, in order to increase the anti-interference capability of communication and ensure timely transmission of information, a ring network switch is provided between the control terminal and the multimedia device, and the ring network switch is suitable for forwarding data between the control terminal and the multimedia device.

[0029] Furthermore, to provide reliable protection for the safety of underground workers, a mining video broadcasting system further includes a shaft sensor network, the shaft sensor network including a gas concentration sensor and a temperature and humidity sensor, the gas concentration sensor being adapted to detect gas concentration data in the shaft in real time, and the temperature and humidity sensor being adapted to detect temperature and humidity data in the shaft in real time;

The audio component includes a loudspeaker microphone 21 and a receiver microphone 22. Both the loudspeaker microphone 21 and the receiver microphone 22 are installed in the multimedia device.

[0049] The video component includes a display screen 23, which is also mounted on the multimedia device.

[0050] In this embodiment, the microphone 22 is used to receive voice feedback from underground workers, and the microphone 21 is suitable for playing the display screen 23 and information sent from the well.

[0051] Specifically, if Figure 1 As shown, the information transmitted by the control terminal 1 to the multimedia device includes audio information and video text information. The audio information is output through the loudspeaker microphone 21, and the video text information is displayed on the display screen 23.

[0052] In this embodiment, the operator can input the required output text information through the external input device of the control terminal 1. The text information is decoded into an audio signal by the control terminal 1 and output through the loudspeaker 21. It can also be decoded into a video text signal by the control terminal 1 and transmitted to the display screen 23 for scrolling display, that is, in the form of scrolling subtitles.

[0053] Specifically, if Figure 1 As shown, a ring network switch 3 is provided between the control terminal 1 and the multimedia device, and the ring network switch 3 is suitable for forwarding data between the control terminal 1 and the multimedia device; in this embodiment, the ring network switch constructs an Ethernet ring network through optical fiber, ensuring effective communication between the underground equipment and the surface equipment, wherein the underground equipment and the surface equipment comply with the GB3836.1-2010 explosive environment equipment standard and can operate safely in a dangerous environment containing methane mixture in a coal mine.

[0054] Specifically, if Figure 1 As shown, a mining video broadcasting system further includes a shaft sensor network, which includes a gas concentration sensor 41 and a temperature and humidity sensor 42. The gas concentration sensor 41 is suitable for detecting gas concentration data in the shaft in real time, and the temperature and humidity sensor 42 is suitable for detecting temperature and humidity data in the shaft in real time.

The data fusion platform 5 is communicatively connected to the control terminal 1. The data fusion platform 5 is suitable for integrating the operating status data of the multimedia equipment and the monitoring data of the well sensor network to generate comprehensive dispatching information.

[0057] In this embodiment, the data of the gas concentration sensor 41 and the temperature and humidity sensor 42 are first transmitted to the control terminal 1 through the ring network switch 3, and then forwarded to the data fusion platform 5 by the control terminal 1.

[0058] Embodiment 2: This embodiment introduces a working method of the mining video broadcasting system of embodiment 1, including:

[0059] The control terminal 1 is adapted to periodically send query commands to a plurality of multimedia devices. After receiving the query commands, the multimedia devices respond to the control terminal 1. After receiving the responses from the multimedia devices, the control terminal 1 sends a sorting command to the multimedia devices. The sorting command includes the IP address of the responding multimedia device and a serial number issued in sequence.

[0060] After receiving the sorting command, the multimedia device verifies whether the IP address in the sorting command is consistent with its own IP address. If they are consistent, it writes the serial number issued in the sorting command into itself;

[0061] After receiving confirmation signals from all multimedia devices, the control terminal 1 generates a communication sequence according to the sequence number;

[0062] In this embodiment, the response data sent by multimedia devices and the shaft sensor network to the control terminal 1 will pass through the ring network switch 3. The QoS mechanism within the ring network switch 3 classifies the response data passing through the ring network switch 3 at the same time (i.e., sensor data > personnel communication information > regular broadcast) and transmits them accordingly to avoid transmission congestion.

[0063] During the process of generating the communication sequence, the operator is aware of the total number of multimedia devices. When the last digit of the communication sequence is less than the total number of multimedia devices, it means that some multimedia devices are offline or have failed. The underground staff will go to the nearby multimedia devices for inspection.

[0064] The steps in the method include:

[0065] S1. Initialization: Control terminal 1 starts and enters the working state. The multimedia device starts and waits for commands from control terminal 1. The ring network switch 3 starts and establishes a communication connection with control terminal 1 and the multimedia device. The gas concentration sensor 41 and the temperature and humidity sensor 42 begin real-time monitoring of relevant environmental parameters of the wellbore and transmit the data to control terminal 1 via the ring network switch 3. The data fusion platform 5 starts and establishes a communication connection with control terminal 1.

[0066] S2. Generate a communication sequence: Control terminal 1 periodically sends a query command to all multimedia devices. After receiving the query command, the multimedia device responds with its own information IP address to control terminal 1.

[0067] Control terminal 1 sends a sorting command to each multimedia device based on the received response information. After receiving the sorting command, the multimedia device verifies whether the IP address in the sorting command is consistent with its own. If it is consistent, it writes the serial number into itself;

[0068] After receiving confirmation signals from all multimedia devices, the control terminal 1 generates a communication sequence based on the sequence number;

[0069] S3. Data integration: The gas concentration sensor 41 and the temperature and humidity sensor 42 continuously monitor the shaft environment and transmit the data in real time to the control terminal 1. The control terminal 1 then forwards the data to the data fusion platform 5.

[0070] The data fusion platform 5 integrates the operating status data of multimedia equipment and the detection data of the well sensor network to generate comprehensive dispatching information for dispatchers to refer to and make decisions;

[0071] S4, information transmission and exception handling: The operator selects one of the three modes of information transmission: designated device transmission, sequential transmission or full network synchronous transmission according to the comprehensive scheduling information generated by the data fusion platform 5;

[0072] The audio information is output in real time through the loudspeaker 21, and the video and text information is displayed on the display screen 23, which facilitates real-time communication with underground workers;

[0073] When a network interruption is detected in a multimedia device, the serial number of the abnormal multimedia device is marked and a No. 1 alarm message is generated through the data fusion platform 5, so that the operator in the well dispatch room can arrange for staff to go for maintenance;

[0074] When abnormal data is detected in the gas concentration sensor 41 and / or the temperature and humidity sensor 42, a second alarm message is generated through the data fusion platform 5, so that the operator in the well dispatch room can operate the control terminal 1 and issue an alarm prompt through the multimedia device to remind the workers in the well to evacuate;

[0075] When a network interruption is detected in the gas concentration sensor 41 and / or the temperature and humidity sensor 42, the abnormal gas concentration sensor 41 and / or the temperature and humidity sensor 42 is marked, and a No. 3 alarm message is generated through the data fusion platform 5, so that the operator in the well dispatch room arranges staff to go for maintenance. If the equipment is restored within 5 minutes, the fault mark is automatically cleared.

[0076] Specifically, in step S4, when it is detected that the gas concentration or temperature and humidity data abnormally exceeds the preset value, the control terminal 1 is suitable for dynamically and automatically switching to the full network synchronous transmission mode according to the comprehensive scheduling information generated by the data fusion platform 5, and broadcasting disaster avoidance instructions to all multimedia devices.

[0077] When detection equipment interruption and environmental data abnormality occur at the same time, such as multimedia equipment failure in a certain area and gas concentration exceeding the standard, the operator manually increases the volume of adjacent multimedia devices to spread the information.

[0078] The above specific embodiments further illustrate the technical problems, technical solutions and beneficial effects solved by the present invention. It should be understood that the above are only specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
