Description

Technical Field

[0001] This utility model relates to the field of highway equipment technology, specifically to a highway video intercom management system. Background Technology

[0002] Currently, automated toll collection and dispensing machines on highways have become increasingly common, significantly reducing labor costs and improving vehicle travel efficiency. However, existing automated toll collection and dispensing machines and other facilities are susceptible to environmental factors during use, such as interference from other electrical equipment, which can prevent vehicles from passing through normally. This necessitates drivers using the intercom terminals at unattended toll booths to communicate with staff on duty and resolve issues, making the application of intercom terminals particularly important.

[0003] Traditional intercom systems mainly rely on analog communication technology, which often suffers from problems such as unstable call quality, signal transmission delay, poor video quality, and poor reliability. They cannot meet the needs of modern intelligent systems, especially in areas requiring remote management, video intercom, high-quality voice, high stability, and high reliability. Traditional technologies are gradually becoming inadequate for increasingly complex usage scenarios. Utility Model Content

[0004] The main objective of this invention is to overcome the deficiencies of the aforementioned background technology and provide a highway video intercom management system.

[0005] To achieve the above objectives, the present invention proposes a highway video intercom management system, comprising a video intercom server, a management computer, a monitoring center intercom extension, at least two manual toll booth video intercom terminals, and at least two card-operated video intercom terminals. The video intercom server, the management computer, the monitoring center intercom extension, and the at least two manual toll booth video intercom terminals are all connected to a core switch. Each card-operated video intercom terminal includes a first control terminal module, a first video module, and a first audio module. The first video module and the first audio module are both connected to the first control terminal module. The first control terminal module is connected to a corresponding first ring network switch. Two adjacent first ring network switches are connected in series, and the first ring network switches at both ends are connected to the card-operated switches to form a ring network. The card-operated switches are connected to the core switch. By configuring the video intercom server and initializing the video intercom terminals at manual toll booths and card-operated video intercom terminals through the management computer, the system can be flexibly adjusted and optimized according to actual needs, improving its customizability and adaptability. The ring network formed by the card-operated switch and the first ring network switch allows for automatic switching in the event of a single point of failure, ensuring uninterrupted communication and greatly improving system stability and reliability. This guarantees normal operation in scenarios like highways where high communication continuity is required.

[0006] To further optimize the technical solution, the card-operated video intercom terminal is integrated and installed on the card issuing machine, payment machine and / or emergency telephone box on the side of the highway at the toll station.

[0007] The technical solution is further optimized. The video intercom terminal of the manual toll booth is set on the operating table inside the toll booth. The video intercom terminal of the manual toll booth includes a second control terminal module, a second video module and a second audio module. The second video module and the second audio module are both connected to the second control terminal module. The second control terminal module is connected to the corresponding second ring network switch. Two adjacent second ring network switches are connected in series. The second ring network switches at both ends are connected to the core switch to form a ring network.

[0008] To further optimize the technical solution, both the first video module and the second video module include a camera, a display screen, and a video signal processing unit. The camera is connected to the video signal processing unit, and the video signal processing unit and the display screen are respectively connected to the corresponding first control terminal module or the second control terminal module.

[0009] To further optimize the technical solution, the video signal processing unit integrates a video encoding chip of any one of the encoding standards H.264 / AVC, H.265 / HEVC, VP8, VP9, ​​and AV1 to process video data, encapsulates the encoded video data into RTP data packets, and controls the streaming media session through the RTSP protocol. The video signal processing unit also supports the SIP protocol.

[0010] To further optimize the technical solution, both the first audio module and the second audio module include a microphone, a speaker, an audio amplifier, and an emergency call button. The microphone and the speaker are both connected to the audio amplifier, and the audio amplifier and the emergency call button are respectively connected to the corresponding first control terminal module or the second control terminal module.

[0011] To further optimize the technical solution, the audio amplifier integrates a voice encoding chip of any one of the encoding standards G.711, G.729, G.722, and G.726 to process audio data, encapsulates the encoded audio data into RTP data packets, and controls the streaming media session through the RTSP protocol. The audio amplifier also supports the SIP protocol.

[0012] The technical solution has been further optimized. The core switch, the card switch, the first ring network switch and the second ring network switch are all connected by two-core optical fibers and support the ERPS fast ring network redundancy protocol, with a fault switching time of ≤20ms.

[0013] To further optimize the technical solution, the video signal processing unit and the audio amplifier are internally integrated with a hardware encryption module. The hardware encryption module is connected to the corresponding first ring network switch or second ring network switch. The hardware encryption module uses SRTP to perform hardware encryption processing on the audio and video data before encapsulating it into RTP data packets, and protects the SIP signaling through the TLS protocol.

[0014] The technical solution has been further optimized, and the card switch now supports 22 GE gigabit Ethernet ports, 12 GX gigabit optical ports, and 4 FX1X9 optical modules.

[0015] The beneficial effects of this utility model include: configuring the video intercom server through video intercom management software on the management computer, setting parameters such as audio and video data storage strategies and session management rules, and simultaneously initializing the video intercom terminals and card-operated video intercom terminals of each manual toll booth, facilitating flexible adjustments and optimizations according to actual needs, and improving the customizability and adaptability of the system; the card-operated video intercom terminals, through the ring network formed by the card-operated switch and the first ring network switch, can automatically switch within less than 20ms when a single point of failure occurs in the system, ensuring uninterrupted communication, greatly improving the stability and reliability of the system, and guaranteeing normal operation in scenarios such as highways where high communication continuity is required.

[0024] Please see Figures 1 to 3The highway video intercom management system disclosed in one embodiment includes a video intercom server 1, a management computer 2, a monitoring center intercom extension 3, at least two manual toll booth video intercom terminals 4, and at least two card-operated video intercom terminals 5. The video intercom server 1, management computer 2, monitoring center intercom extension 3, and at least two manual toll booth video intercom terminals 4 are all connected to a core switch 6. The card-operated video intercom terminal 5 includes a first control terminal module 501, a first video module 502, and a first audio module 503. The first video module 502 and the first audio module 503 are both connected to the first control terminal module 501. The first control terminal module 501 is connected to a corresponding first ring network switch 7. Two adjacent first ring network switches 7 are connected in series. The first ring network switches 7 at both ends are connected to card-operated switches 8 to form a ring network. The card-operated switches 8 are connected to the core switch 6. Specifically, the card reader switch 8 supports 22 GE gigabit Ethernet ports, 12 GX gigabit optical ports, and 4 FX1X9 optical modules to meet diverse needs in different environments and scenarios. It integrates multiple functions such as audio, video, and broadcasting, and supports various communication interfaces, such as network interfaces, camera interfaces, and audio output interfaces. It can realize one-button calling, video intercom, audio broadcasting, and recording functions to meet the needs of different application scenarios. The video intercom server 1, management computer 2, and monitoring center intercom extension 3 are deployed in the station-level monitoring room of the highway operation and management unit, and are connected to the core switch 6 via network cables. The manual toll booth video intercom terminal 4 is set on the operating console inside the toll booth. The card reader video intercom terminal 5 is integrated and installed on the card issuing machine and payment machine at the toll station or on the emergency telephone box on the side of the highway, meeting the communication needs of different areas of the highway. The system meets information needs, improving its practicality and coverage. Terminals support online software upgrades and configuration import / export, greatly simplifying terminal management and maintenance, and enhancing system flexibility and scalability. Video intercom server 1 is responsible for audio and video data forwarding, storage, backup, session management, and system configuration. Management computer 2 is equipped with video intercom management software, providing a human-machine interface for status monitoring, log querying, call recording, and remote control. Monitoring center intercom extension 3 supports two-way audio and video communication with all manual toll booth video intercom terminals 4 and all card-operated video intercom terminals 5. Each device has clearly defined functions and works collaboratively, making the entire system easy to manage and operate, and efficiently realizing video intercom functionality. This system fully considers adaptability to extreme environments, operating stably within a temperature range of -30℃ to 70℃ and a humidity range of 10% to 95%.In this embodiment, the video intercom server 1 is configured using video intercom management software on the management computer 2, setting parameters such as audio and video data storage strategies and session management rules. Simultaneously, the video intercom terminals 4 and card-operated video intercom terminals 5 at each manual toll booth are initialized, including selecting the video encoding chip type and encoding parameters of the video signal processing unit 543, and the voice encoding chip type and encoding parameters of the audio amplifier 546. This allows for flexible adjustments and optimizations based on actual needs, improving the system's customizability and adaptability. Furthermore, the card-operated video intercom terminal 5, connected to the first ring network switch 7 via the card-operated switch 8, can automatically switch over in less than 20ms when a single point of failure occurs, ensuring uninterrupted communication and significantly improving system stability and reliability. This guarantees normal operation in scenarios like highways where high communication continuity is crucial.

[0025] In a specific example, the video intercom terminal 4 of the manual toll booth includes a second control terminal module 401, a second video module 402, and a second audio module 403. The second video module 402 and the second audio module 403 are both connected to the second control terminal module 401. The second control terminal module 401 is connected to the corresponding second ring network switch 9. Two adjacent second ring network switches 9 are connected in series, and the second ring network switches 9 at both ends are connected to the core switch 6 to form a second ring network. Furthermore, the core switch 6, the card switch 8, the first ring network switch 7, and the second ring network switch 9 are all connected by two-core optical fibers and support the ERPS fast ring network redundancy protocol, with a fault switching time of ≤20ms. When a fiber optic link in the network fails, the core switch 6, card switch 8, first ring network switch 7, and second ring network switch 9 support the ERPS fast ring redundancy protocol. Since each of the two-core optical fibers can transmit and receive data, the network will automatically switch to the backup link within 20ms when one of the optical fibers in the loop breaks. This ensures the normal transmission of audio and video data, does not affect the continuity of communication, guarantees the continuous operation of the system, enhances the reliability of the video intercom management system in critical situations, and greatly improves the system's stability and emergency response capabilities.

[0026] In a specific example, both the first video module 502 and the second video module 402 include a camera 541, a display screen 542, and a video signal processing unit 543. The camera 541 is connected to the video signal processing unit 543, and the video signal processing unit 543 and the display screen 542 are respectively connected to the corresponding first control terminal module 501 or second control terminal module 401. The video signal processing unit 543 integrates a video encoding chip of any one of the encoding standards H.264 / AVC, H.265 / HEVC, VP8, VP9, ​​and AV1 to process video data, encapsulates the encoded video data into RTP data packets, and controls the streaming media session through the RTSP protocol. The video signal processing unit 543 supports the SIP protocol. Both the first audio module 503 and the second audio module 403 include a microphone 544, a speaker 545, an audio amplifier 546, and an emergency button 547. The microphone 544 and the speaker 545 are both connected to the audio amplifier 546. The audio amplifier 546 has a maximum power of 60W, ensuring clear voice communication even in the high-noise environment of the toll station. When it is necessary to broadcast to the driver or toll collector, the instruction information can be quickly transmitted to the driver or toll collector in the toll station through the speaker 545. Audio amplifier 546 and help button 547 are respectively connected to the corresponding first control terminal module 501 or second control terminal module 401. Audio amplifier 546 integrates a voice encoding chip of any one of the encoding standards G.711, G.729, G.722, and G.726 to process audio data, encapsulates the encoded audio data into RTP data packets, and controls the streaming media session through the RTSP protocol. Audio amplifier 546 supports the SIP protocol. Video signal processing unit 543 and audio amplifier 546 integrate a hardware encryption module 548. Hardware encryption module 548 is connected to the corresponding first ring network switch 7 or second ring network switch 9. Hardware encryption module 548 uses SRTP to perform hardware encryption processing on audio and video data before encapsulating it into RTP data packets, and protects SIP signaling through the TLS protocol. During data transmission, the IP / RTP / RTSP protocol is combined to achieve high-quality video intercom functionality. Video quality is guaranteed even in low-bandwidth and high-latency environments. Compared to traditional analog systems, video stuttering rate is reduced by more than 90%, providing clear and stable video call effects. This effectively enhances visual communication capabilities in emergency situations, especially under low-bandwidth conditions, ensuring the system's applicability in complex environments. Furthermore, the audio and video data are encrypted using SRTP through a hardware encryption module to ensure data security during network transmission. SIP signaling is protected by the TLS protocol to prevent tampering or theft of signaling.

[0027] In this embodiment of the utility model, when the toll collector communicates with the monitoring room administrator, the toll collector initiates a request for help by pressing the help button 547. For example, if the toll collector encounters a special situation in the toll booth, pressing the help button 547 on the manual toll booth video intercom terminal 4 will trigger a call request from the terminal to the video intercom server 1 via the SIP protocol. After receiving the request, the video intercom server 1 establishes a session connection with the monitoring center intercom extension 3 according to the system configuration and the current network status. At this time, the video data collected by the camera 541 is encoded by the video encoding chip of the video signal processing unit 543 and encapsulated into RTP data packets, which are then controlled via the RTSP protocol. The streaming media session is transmitted over the network to the video intercom server 1, and then forwarded by the server to the monitoring center intercom extension 3. At the same time, the audio data collected by the microphone 544 is encoded by the voice encoding chip of the audio amplifier 546, encapsulated into RTP data packets, and transmitted to the monitoring center intercom extension 3 via the RTSP protocol. Similarly, the audio and video data collected by the monitoring center intercom extension 3 are also transmitted to the display screen 542 of the manual toll booth video intercom terminal 4 for display and played out through the speaker 545. The management personnel of the monitoring center can conduct two-way audio and video communication with the toll collectors through the monitoring center intercom extension 3 to understand the situation and take timely action.

[0028] When a driver encounters a problem at the toll booth, the driver presses the help button 547 on the toll booth video intercom terminal 5. This terminal also initiates a call request to the video intercom server 1 via the SIP protocol. After receiving the request, the video intercom server 1, based on the system configuration and the current busy status of the toll booth video intercom terminal 4, initiates an audio and video intercom request to an idle toll booth video intercom terminal 4 or the monitoring center intercom extension 3, prioritizing the toll booth video intercom terminal 4. After the toll booth personnel accept the request, a session connection is established with the toll booth video intercom terminal 4, and the control terminal modules of the two terminals (the first control terminal module 501 and the second control terminal module 401) send an activation command to the corresponding camera 541 and a display command to the display screen 542, respectively. After receiving the activation command, camera 541 starts recording live video of the scene. At this time, the video data collected by cameras 541 on both sides is encoded by the video encoding chip of video signal processing unit 543, encapsulated into RTP data packets, and transmitted to video intercom server 1 via the RTSP protocol to control the streaming media session. The server then forwards the data to the display screens 542 on both sides of the terminal. Meanwhile, the audio data collected by microphone 544 is encoded by the voice encoding chip of audio amplifier 546, encapsulated into RTP data packets, and transmitted to video intercom server 1 via the RTSP protocol. The server then forwards the data to the speakers 545 on both sides of the terminal for playback, realizing two-way audio and video communication between the toll collector and the driver, enabling timely understanding and handling of the situation.
