Embodiment 1

[0045]An elevator emergency call system, including the minimum embedded microcontroller system, 4G communication circuit, pyroelectric sensing circuit, Hall sensing circuit, one-key dialing circuit, power supply circuit, real-time clock circuit and data storage circuit; When there is a person, the pyroelectric sensing circuit and the Hall sensing circuit detect that there are people in the elevator and the elevator closes the door. The minimum system of the embedded microcontroller uses the internal timer of the system to calculate the duration. When the set value is reached, the minimum system of the embedded microcontroller Use the serial port to send call instructions to the 4G communication circuit, and the 4G communication circuit will dial the designated rescue phone immediately. After the call is over, the real-time clock circuit will obtain the trapped time and dialing time, and save the phone recording file to the data storage circuit. The embedded micro-controller min...

Embodiment 2

[0055] Based on the control method of above-mentioned elevator emergency call system, comprise the steps:

[0056] 1) When the pyroelectric sensor detects that there is a person in the elevator car, and the Hall sensor detects that the elevator door is closed, the embedded micro-controller minimum system uses the internal timer of the system to start timing;

[0057] 2) After reaching the set value, it is detected that there are still people in the elevator car and the elevator door is closed, it is determined that the elevator is trapped, and the embedded microcontroller uses the serial port to send a call command to the 4G communication circuit, and the 4G communication circuit immediately dials Designated rescue phone number; in addition, trapped passengers can dial the designated rescue phone number by pressing the button in the one-key dialing circuit and wait for rescue, and the embedded microcontroller controls the real-time clock circuit to obtain the trapped time and d...

Abstract

The invention discloses an elevator emergency calling system and a control method. The elevator emergency calling system comprises an embedded microcontroller minimum system, a 4G communication circuit, a pyroelectric sensing circuit, a Hall sensing circuit, a one-key dialing circuit, a power circuit, a real-time clock circuit and a data storage circuit. The embedded microcontroller minimum systemcomprises a main control chip, and a reset circuit, a clock circuit and a starting circuit which are electrically connected with the main control chip. The 4G communication circuit, the pyroelectricsensing circuit, the Hall sensing circuit, the one-key dialing circuit, the power supply circuit, the real-time clock circuit and the data storage circuit are respectively connected with the differentpins of the main control chip through the conducting wires. The system is high in intelligent degree, the rescue efficiency is improved, and the passenger trapping time is shortened. The 4G communication circuit is arranged to achieve the wireless communication with the outside, the signals are not easy to interfere, the attenuation degree is low, the conversation quality is high, and the rescueis facilitated when people are trapped in an elevator. Compared with an existing wired connection mode, according to the present invention, the conducting wires are saved, the maintenance is convenient, and the cost is low.

Description

technical field [0001] The invention belongs to the technical field of elevators, and in particular relates to an elevator emergency call system and a control method. Background technique [0002] The elevator emergency alarm device is a device that allows the trapped people to communicate with the outside world simply and quickly when the elevator breaks down and people are trapped. [0003] At present, the emergency alarm devices of most elevators in use use wired intercom connections, that is to say, the five parties of the emergency alarm devices are directly connected through lines. This form of wired connection is naturally stable and reliable enough during use, but it has the following disadvantages: [0004] 1. At present, residential elevators occupy the largest number, and residential elevators are scattered. If the emergency alarm device of the elevator is connected by cable, the project volume will be large; [0005] 2. If the elevator is far away from the duty...
