Accurate perception of the seismic information Avoid earthquake damage to the elevator Timely rescue of trapped person Participate in the State administration of quality supervision the 2008QK21 subject research Participate in the National elevator shockproof standards drafting SYSTEM OVERVIEW The elevator earthquake detector is used in conjunction with the elevator control system, make the elevator before the earthquake happened or occurs effective enter into the control operation of the equipment. Before the earthquake arrival, the elevator earthquake detector early detection to seismic waves, output alarm contacts to the elevator control system, the elevator control system according to the contacts state in the recent floor flat layer to open the door, release the passengers out of the elevator, the maximum save the life safety of the passengers, ensure that the elevator equipment is not compromised. FEATURES AND PARAMETERS Input voltage:AC220 10% 50 Hz 60 Hz Output way:2 relay output Contacts capacity:1.0 A 30 V DC, 0.5 A 125 V AC Frequency response:0.1 Hz 30 Hz Level 1 alarm acceleration threshold set range:0.2 m/s 1m/s Level 2 alarm acceleration threshold set range:0.4 m/s Acquisition accuracy:0.01m/s Reset way:manual reset Alarm record:100 strips Overall Power Consumption: 1 W Weight:1kg SYSTEM PRINCIPLE Product collection when the earthquake ground X/Y/Z three of the direction of ground motion acceleration, accurate detection of the earthquake happened, when P wave arrived acceleration sensor detected early earthquake of vertical vibration then output corresponding electric signals, through the filter and amplification by Analog to Digital Converter for microprocessor processed. When S wave arrival, acceleration sensors to detect the horizontal vibration, and output corresponding electric signals, through the filter and amplification by Analog to Digital Converter for microprocessor processed. The instrument has two road relay output, respectively is level 1 alarm output, level 2 alarm output, access the elevator control system respectively, for the elevator control system collection. Level 1 alarm output is instruments detected early earthquake P wave or low vibration acceleration of earthquake movement after output, is a low-level output, used to judge may be happen earthquake, after Level 1 alarm relay action, if in 10s inside not have to achieve the Level 2 alarm ground vibration signal, the product to be automatic reset, and contacts signals disappear. Level 2 alarm output corresponding higher ground motion of the output of the acceleration, can't automatic reset, and need professional elevator operator to inspection elevator, and after confirm the elevator without any fault then manually reset.
