Remote monitoring system of elevator

Abstract

The invention discloses a remote monitoring system of an elevator, comprising an earthquake sensor, a fire detection sensor, an earthquake detection control device, a fire detection control device, an elevator operation control device, an elevator system, a monitoring device and an information processing and displaying module, wherein, the output end of the earthquake sensor is connected with the input end of the earthquake detection control device, the output end of the fire detection sensor is connected with the input end of the fire detection control device, the output end of the earthquake detection control device is respectively connected with the input ends of the elevator operation control device and the monitoring device, the output end of the fire detection control device is respectively connected with the input ends of the elevator operation control device and the monitoring device, the output end of the elevator operation control device is connected with the elevator system in series and then is connected with the input end of the monitoring device, and the output end of the monitoring device is connected with the input end of the information processing and displaying, module. The remote monitoring system has precise detection and real-time monitoring, can ensure communication lines even though the earthquake or fire occurs, and can maintain the monitoring performance.

Description

technical field [0001] The invention relates to the technical field of an elevator remote monitoring system. Background technique [0002] In the past, in order to grasp the impact of earthquakes on remote monitoring objects, P-wave seismic sensors and S-wave seismic sensor. [0003] The P wave 101 is called a longitudinal wave or a density wave, and is a small shock wave that first reaches a building 104 through a rock plate 103 from a seismic source 102 that destroys foundations or the like. The S wave 105 is called a shear wave, and is a large shaking wave transmitted through the rock plate 103 after the arrival of the P wave. The P wave varies depending on the density and rigidity (a type of hardness) of the foundation, but it is said that the speed of the P wave is about 6 km per second, and the speed of the S wave is 3.5 km per second. That is, the P wave speed is nearly twice that of the S wave, and the conduction speed is fast. [0004] When the existing elevator...

Problems solved by technology

As a result, the monitoring center is unable to communicate due to excessive communication load

[0007] When such a situation occurs, even if a signal of the occurrence (such as an emergency call signal from the car or a request signal from a customer, etc.) , and therefore cannot receive these signals

Therefore, it may have a great impact on the remote monitoring system as a whole, and it is difficult to ensure the safety of the monitored objects
