Product Description

The elevator seismic monitor is a device used in conjunction with the elevator control system to effectively enable the elevator to enter controlled operation before or when an earthquake occurs. Before an earthquake arrives, the elevator seismic monitor detects seismic waves in advance, and outputs alarm contacts to control the elevator control system to open the elevator door at the nearest floor, releasing the passengers in the elevator, saving the lives of passengers, and ensuring that the elevator equipment is not damaged. damaged. The system mainly has the following advantages:

(1) High-precision, low-noise seismic data collection;

(2) Quickly and accurately judge earthquake events;

(3) Two-level trigger signal output. This instrument has three contact outputs, namely first-level alarm contact output, second-level alarm contact output and fault contact output. Each of them is connected to the elevator-related system for collection of elevator system operation. control signal.

Working principle

 

The product collects ground motion acceleration in the three directions of X/Y/Z during an earthquake to accurately detect the occurrence of an earthquake. When the P wave arrives, the acceleration sensor detects the vibration in the vertical direction in the early stage of the earthquake and outputs the corresponding electrical signal, which is filtered and amplified through The analog-to-digital converter is sent to the microprocessor for corresponding processing. When the S wave arrives, the acceleration sensor detects the vibration in the horizontal direction and outputs a corresponding electrical signal, which is amplified by filtering and sent to the microprocessor through an analog-to-digital converter for corresponding processing.

This instrument has three relay outputs, namely first-level alarm output, second-level alarm output and fault contact output, which are respectively connected to the elevator control operation system for collection by the elevator control system. The first-level alarm output is the output after the instrument detects early P-wave vibration or low seismic motion acceleration. It is a lower-level output and is used to judge that an earthquake may occur. After the first-level alarm relay is activated, if within 10 seconds If the ground vibration signal does not reach the second level alarm, the product will automatically reset and the contact signal will disappear. The secondary alarm output corresponds to the output of higher ground motion acceleration and cannot be automatically reset. Professional elevator operators need to check the elevator and manually reset it after confirming that there is no fault in the elevator.
