As shown in Tables 1-2, it is a voltage and power requirement table of each board card of the passenger information system controller:

[0077] Table 1-2

[0078] Specifically, the UIC board comprises:

[0084] When the UIC568 bus signal detection circuit detects the current signal state and receives the CPU control instruction, the relay is controlled to act, the first relay controls the selection of the standby audio or automatic and manual broadcast for output, the second relay controls whether the output audio selected by the first relay is sent to the UIC568 bus 1.2 line; the third relay controls the UIC568 bus 5.6 line to be 24V when there is automatic and manual broadcast. The UIC board outputs analog audio to the UIC568 bus while setting 24V voltage on the UIC568 bus 5.6 line, and the car controller detects the 24V voltage signal internally to switch the audio, switch the broadcast audio signal for output, and thus realize the public station broadcast function such as automatic broadcast, manual broadcast and the like.
