Fig. 2 is an electrical schematic diagram between the car interphone and the machine room interphone of the invention.
Detailed Description
The invention is further described below in conjunction with the appended drawings and detailed description.
Referring to fig. 1 and 2, the room interphone 10 shown in the figures includes an MCU module U2, the room control board 20 provides the MCU module U2 with a system communication interrupt signal 1 and a system power failure signal 2, the door zone indicator light 11 or/and the door zone speaker 12 in the room interphone 10 are connected to a signal output terminal of the MCU module U2, and the rescue button 13 is connected to a signal input terminal of the MCU module.
The MCU module U2 in the machine room interphone 10 is in communication connection with the MCU module U1 in the car interphone 40 through the flat cable 30. A microphone MIC 14 and a rescue light 15 are also provided in the room interphone 10.
A charging plate 51 in an interphone power supply 50 of the car interphone 40 is connected with a battery 52, the charging plate 51 outputs power sources 24V +, 24V-to supply power to a DC/DC isolation module U3, the DC/DC isolation module U3 provides a group of isolation power sources D24V, the isolation power sources D24V are connected to a leveling switch K1 on a car through a double-link switch RY1 in the car interphone 40 and used by a leveling switch K1 on the car, and a system power source + is connected to a loop between the isolation power source D24V and the leveling switch K1.
