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.

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.


FUNCTION CHARACTERISTICS

BC100 traction drive elevator brake capability detector is a kind of equipment to detect if the traction elevator braking capacity is qualified .

The barrier is made of pe material which is strong enough for daily use, equiped with the wheels it can be moved easily, with the hinges it can be folded or connected as long as you want.
Bright yellow catches more attention, the customized logo and warning words can be wonderful advertisement for your company
