Technical Field

The utility model relates to an intercom technical field especially relates to an intelligence intercom device.

Background

The elevator intercom device is a communication device arranged in an elevator car, and when the elevator breaks down (for example, the elevator suddenly stops working due to power failure and stops running, and then the elevator suddenly falls down), the elevator intercom device can be started to communicate with a property monitoring center according to an elevator alarm bell, and the property or security personnel are informed to rescue on site.

In fact, the elevator alarm bell is installed at a higher position, and for children with shorter heights, the elevator alarm bell cannot be pressed.

The present invention will now be further described with reference to the accompanying drawings and detailed description.

Referring to fig. 1, 2 and 3, the present embodiment provides an intelligent intercom device including a housing 1, a panel 2, and a PCB circuit board 3.

As shown in fig. 1 and 2, a mounting groove 100 for mounting the PCB 3 is formed on the housing 1, and the panel 2 is mounted in a notch of the mounting groove 100.

The shell 1 is provided with a power interface 4; in this embodiment, it is preferable that the power interface 4 is a D-type power interface. When concrete, power source 4 can also adopt the Micro usb interface or Type-C interface.

The panel 2 is provided with a loudspeaker 5, a microphone 6, an alarm button 7, a camera 8 and a human body infrared sensor 9.

On the PCB circuit board 3 are integrated a microprocessor 31, a rechargeable power supply 32, an AC-DC converter 33, a sound card module 34, a voltage detection circuit module 35, an acceleration sensor 36, and a wireless communication module 37.

In this embodiment, preferably, the microprocessor 31 adopts an msp430fg4618 controller, and the msp430fg4618 controller has the advantage of ultra-low power consumption, so as to save power. The wireless communication module 37 employs an RF communication module.

The speaker 5, the microphone 6, the alarm button 7, the camera 8, the human body infrared sensor 9, the rechargeable power supply 32, the AC-DC converter 33, the sound card module 34, the voltage detection circuit module 35, and the acceleration sensor 36 are all conventional electronic devices.

In the embodiment shown in fig. 3, the power interface 4 is electrically connected to the power supply of the elevator (not shown) via a wire. When the elevator has power failure, the power interface 4 has no power input.

For those skilled in the art, the technical means for electrically connecting the power interface 4 with the power supply of the elevator through a wire is conventional technical means, and will not be described in detail herein.

The input end of the AC-DC converter 33 is electrically connected to the power interface 4, and the output end of the AC-DC converter 33 is electrically connected to the rechargeable battery 32 to charge the rechargeable battery 32. The rechargeable battery 32 is electrically connected to a power supply terminal of the microprocessor 31 to supply power to the microprocessor 31.

The input end of the AC-DC converter 33 is further electrically connected to the voltage detection circuit module 35, and the voltage detection circuit module 35 detects the voltage at the input end of the AC-DC converter 33 and transmits the voltage to the microprocessor 31; the voltage detection circuit module 35 detects whether the elevator has power failure (the voltage detection circuit module 35 detects the voltage at the input end of the AC-DC converter 33 and transmits the voltage to the microprocessor 31.
