Further, the alarm function is described as follows: the signal collector is responsible for encoding the input signals of piezoelectric acceleration sensors, leveling sensors, smoke sensors, door magnetic sensors, human body infrared sensors, etc., and converts the encoded signals in serial The way of communication is passed to the ARM2 processing unit. When any one of the piezoelectric acceleration sensor, leveling sensor, and smoke sensor acts, the ARM2 processing unit starts the program and controls the 3G module to send an alarm signal to the background server. The whole process is automatically executed by the internal program. The touch screen is provided with a manually triggered alarm button. When the alarm button is activated, the touch screen will input the collected alarm signal into the ARM1 processing unit, and the ARM1 processing unit will call the standby video information in the storage and send it to the touch screen. The display screen displays; the ARM1 processing unit establishes full-duplex communication with the ARM2 processing unit, and sends the alarm signal to the background server through the 3G module, and the server automatically sends the information to the corresponding maintenance personnel/property personnel’s mobile phone through the APP and SMS , and automatically dial the corresponding service call; at the same time, the video call request is sent to the background server through the 3G module, and the multifunctional Internet of Things terminal used for the elevator establishes a video call channel with the background. In the video call function of the multifunctional Internet of Things terminal used for elevators, the camera is responsible for video information collection at the elevator end, and the radio head is responsible for voice signal collection at the elevator end; the 3G module completes video signals and image signals with the background server. receiving and sending; the 2G module completes the receiving and sending of voice signals with the background server.

Further, in order to ensure the function of the multi-functional Internet of Things terminal used in the elevator is well guaranteed, an emergency power supply is also provided. When the emergency power supply detects that the input voltage of the normal input power supply is higher than or lower than 20% of the normal voltage, it starts to supply power to the multifunctional Internet of Things terminal for the elevator; when the ARM1 processor detects that the normal input voltage signal is lost, it controls the touch The output brightness of the display is increased to maximum, providing intelligent auxiliary emergency lighting.

Further, in the present invention, when no alarm signal is generated, the touch display screen in the elevator car can play rich and colorful content under the control of the ARM processor, and can display various information such as time, weather forecast, advertisement, flight, etc. ; When an alarm signal is generated, the touch display screen in the elevator car will automatically play a comforting video and switch between video monitoring and calling under the control of the ARM processor. With the participation of hardware decoding or software decoding, the multi-functional Internet of Things terminal for elevators can play video in almost unlimited formats; further, voice prompt services can be realized through touch screens and speakers, and captured by cameras and radios Light and sound signals in the elevator car.

In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

1. Separately transmit video, image and voice signals to improve the quality of communication.

2. The ARM processor adopts two processing units to classify and process signals, which improves the processing capability of the system.
