[0084] Table 1-2

[0085] Specifically, the UIC board includes:

[0086] UIC568 ​​bus signal detection circuit, used to detect the current signal status of UIC568 ​​bus and send it to the CPU board;

[0087] The first relay is used for switching between automatic broadcast, manual broadcast and backup audio;

[0088] The UIC main control chip is connected to the CPU board via the backplane and receives the automatic broadcast or manual broadcast output by the CPU board; the UIC main control chip controls the first relay to select one of the automatic broadcast, manual broadcast and backup audio output according to the current signal state of the UIC bus and the control instruction of the CPU board.

[0089] It can be understood that the audio files of automatic broadcast and manual broadcast are stored in the CPU hard disk and output through the CPU sound card, and the backup audio is connected to the UIC board through Ethernet.

[0090] When performing automatic broadcasting and manual broadcasting (service information broadcasting), the audio file is output as analog audio through the CPU board sound card and output to the UIC board through the back panel. The UIC board performs voltage transformation, calculation and amplification, and then selects the sound source according to the relay switch; the backup audio can be connected to the UIC board through the front panel, and the sound source is selected according to the relay switch after voltage transformation, calculation and amplification. The UIC board contains a UIC568 ​​bus signal detection circuit, which detects the voltage of lines 5, 6, 7, and 8 of the UIC568 ​​bus to determine the current broadcast priority. When a telephone is used for manual broadcasting, there are 24V voltage signals on lines 5, 6, 7, and 8 of the UIC568 ​​bus. The UIC board can detect the UIC568 ​​bus status at this time through hardware and send this signal status to the CPU board. The CPU board can determine that it is currently in a manual broadcast state and record it. Among them, manual broadcasting includes full-train manual broadcasting and single-car broadcasting. When only lines 5 and 6 of the UIC568 ​​bus have 24V voltage signals, it can be determined that the current train is in an automatic broadcast / service information broadcast state. Rail vehicle public broadcasting specifically includes full-train manual broadcasting, manually triggered full-train service information broadcasting, automatically triggered full-train service information broadcasting, standby broadcasting, single-car broadcasting, overcrowded broadcasting, and entertainment audio. The priority of the above broadcasts decreases step by step. Among them, entertainment audio includes video accompaniment, background music, and FM, which are selected and switched through the operating screen.

[0091] When the UIC568 ​​bus signal detection circuit detects the current signal state and receives the CPU control command, it will control the relay to act. The first relay controls the selection of standby audio or automatic or manual broadcast output. The second relay controls whether to send the output audio selected by the first relay to the UIC568 ​​bus line 1.2; the third relay controls when there is automatic or manual broadcast, and sets the UIC568 ​​bus line 5.6 to 24V. The UIC board outputs analog audio to the UIC568 ​​bus and sets the UIC568 ​​bus line 5.6 to 24V voltage. The car controller detects the 24V voltage signal and performs audio switching internally, switching the broadcast audio signal for output, thereby realizing public station announcement functions such as automatic broadcast and manual broadcast.

[0092] Specifically, the CPU board is used to communicate with the vehicle TCMS through TDRP; the CPU board includes a CPU core chip, and the CPU core chip has:

[0093] SATA interface for connecting to SATA interface hard disk;

[0094] Sound card output audio interface for broadcast and service audio output;

[0095] PCIE interface for communication with the backplane and board;

[0096] USB interface for data update;

[0097] VGA interface for CPU board operation display;

[0098] Ethernet port for Ethernet data communications.

[0099] The CPU board establishes communication with TCMS through TDRP to obtain information such as train operation, and combines the train position data obtained through the Beidou board to comprehensively identify and judge the data related to train operation, thereby establishing the operation of the broadcast and intercom system and information display system, and realizing data distribution and logic control of the display terminal, broadcast and intercom terminal through Ethernet, serial interface and analog audio interface.

[0100] Specifically, the CPU board brings out the SATA interface through the CPU core chip, and by connecting to the SATA interface hard disk, the system files, applications, voice text files, etc. can be stored in the SATA hard disk; the audio interface is brought out through the sound card to realize broadcast and service audio output; the data communication with the backplane and other chassis boards is realized through the PCIE interface; the front panel is equipped with a USB port to realize data update, and a VGA interface is set for CPU board system operation display; an Ethernet port is brought out for Ethernet data communication.

[0101] In a specific embodiment, the dining car power board adopts a 110V to 12V power conversion circuit to integrate the power boards of each chassis to realize power supply to each board in the chassis; wherein, the card slot width of the dining car power board is 10HP; the card slot width of the AC control board is 8HP; the card slot width of the UIC board is 8HP; the card slot width of the Beidou communication board is 6HP; the card slot width of the TRDP board is 8HP; the card slot width of the CPU board is 14HP; the card slot width of the seat display access board is 14HP; the card slot width of the firewall board is 8HP; the card slot width of the dining car switch board is 8HP.
