[0002] As my country's cities expand exponentially, urban transportation challenges are becoming increasingly prominent. With its safety, punctuality, and speed, the subway is playing an increasingly important role in expanding urban space, building rapid, three-dimensional urban transportation networks, and improving the urban traffic environment.

[0003] With the need for sustainable development and the healthy development of urban transportation, the construction of subway emergency response capabilities has become increasingly important. Changsha Metro currently has 6 operating lines, 148 stations, and an average daily passenger volume of approximately 2 million. However, the communication methods for emergency response lack visualization, real-time, and intelligence. In emergency situations, drivers, dispatchers at all levels, and emergency support technicians are unable to effectively form a multi-party communication network. Fault information and dispatch orders are transmitted repeatedly and with ambiguous content. Existing intercom equipment also has defects. The central control end lacks proactive supervision of the platform and driver end. Communication is generally carried out through 800-megabyte intercoms or voice intercom platforms, which have the disadvantages of unstable communication signals, only intercom without amplification, lack of confidentiality and high security risks, and inability to record and store audio. Summary of the Invention

[0020] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, a detailed description will be given below with reference to the accompanying drawings and specific embodiments.

[0021] The utility model aims at solving the existing problems and provides a visual intercom system.

[0022] In one embodiment, referring to Figure 1 and Figure 2 As shown, it includes the OCC command center management host 1, the DCC dispatch sub-control desktop management host 2, the train cab visual intercom terminal 3 and the subway station duty manager visual mobile intercom terminal 4;

[0023] The OCC Command Center Management Host 1 manages all devices within the system, enabling broadcasting and video intercom functions for devices in various areas. The host features a one-touch emergency broadcast button, allowing for a single-touch broadcast to all devices in an emergency.

[0024] Each DCC dispatch sub-control desktop management host 2 manages the equipment in the trains of each line and supports functions such as video intercom, broadcasting, monitoring and surveillance.

[0025] The visual intercom terminal 3 in the train cab can initiate a call to the superior control console and conduct intercom after approval.

[0026] The visual mobile intercom terminal 4 for the subway station manager on duty has the functions of visual intercom / voice intercom. Emergency calls can be made to the sub-control desk through the device to carry out on-site disposal in a timely manner.

[0027] The OCC command center management host 1 is communicatively connected to the DCC dispatch sub-control desktop management host 2, and the train cab visual intercom terminal 3 and the subway station duty manager visual mobile intercom terminal 4 are respectively communicatively connected to the DCC dispatch sub-control desktop management host 2.

[0028] The OCC command center management host 1 and the DCC dispatch sub-control desktop management host 2 can have two-way visual intercom.

[0029] The train cab visual intercom terminal 3 and the subway station duty manager visual mobile intercom terminal 4 can respectively conduct visual intercom with the DCC dispatch sub-control desktop management host 2, and can also respectively conduct visual intercom with the OCC command center management host 1.

[0030] The train cab video intercom terminal 3 has a Beidou positioning function and can trace vehicle operation data.

[0031] The DCC dispatch sub-control desktop management host 2 includes a microphone base 21 and a screen 22, a microphone 23, a camera 24, a fingerprint recognition 25 and a control key 26 arranged on the microphone base.

[0032] The DCC dispatch sub-control desktop management host 2 includes a station control room desktop management host 201, a safety and supervision department desktop management host 202, a vehicle department desktop management host 203, and a communication and signaling department desktop management host 204. The station control room desktop management host 201, the safety and supervision department desktop management host 202, the vehicle department desktop management host 203, and the communication and signaling department desktop management host 204 are respectively connected to the OCC command center management host 1, and are also connected to the train cab visual intercom terminal 3 and the subway station duty manager visual mobile intercom terminal 4.

[0033] The intercom, monitoring, broadcast, and alarm systems for multi-party calls and real-time display in emergencies primarily utilize a "multi-level sub-control management, unified command" management model. The system features a three-level management model: "terminal - monitoring / sub-control center - command center." The command center houses a system management server and management host, while each sub-control center houses an intercom management host. The command center manages all intercom terminals, while each sub-control center manages its corresponding intercom terminal. This creates a multi-level management intercom, monitoring, broadcast, and alarm system, ensuring that the failure or malfunction of any device does not affect the operation of the entire system.

[0034] Main functions of the system
