Method and apparatus for controlling an elevator system

The method and the apparatus are used for securely controlling an elevator system (3) comprising a drive unit (38) which allows an elevator car (36) located in an elevator shaft (35) to move and whichis controlled in a secured manner by a control device (100) in such a way that during normal operation, the elevator car (36) can move to at least two access points to the elevator shaft (35) at which doors (30A, 30B) are provided. The elevator car (36) does not move or moves only to a limited extent if an individual is in the elevator shaft (35). A monitoring unit (10A; 10B) and a monitoring sensor (11A; 11B) that allow changes in state to be detected are associated with at least one of the doors (30A, 30B). The monitoring unit (10A; 10B) is equipped with a battery (14) and can be switched to an autonomous mode when the elevator system (3) is entirely or partially out of order. The monitoring unit (10A; 10B) is connected to the monitoring sensor (11A; 11B) and, in the autonomous mode, monitors the state of the monitoring sensor (11A; 11B) and records state data; furthermore, the monitoring unit (10A; 10B) is connected to a securing unit (1) which reads the recorded state data from all connected monitoring units (10A; 10B), evaluates said state data and prevents the elevator system (3) from being put into the normal mode of operation if a change in the state of one of the monitored doors (30A; 30B) has been detected. The monitoring sensor (11A, 11B) is a switching contact which is coupled to the associated door lock (31A; 31B) and via which a monitoring signal is transmitted from an output to an input of the monitoring unit (10A; 10B). According to the invention, the monitoring signal is in the form of a sequence of pulses.

A panoramic monitoring device, system and method for an airport run-slip area

The invention relates to a panoramic monitoring device, system and method of an airport skid area. The method uses a plurality of monitoring devices to obtain the space scene light of the airport skid area through a camera lens, and converts the light into electric charge through a CCD sensor and passes it through an analog-to-digital converter chip. converted into a digital signal; the image acquisition module collects the real-time video image data stream of the airport run-and-skid area; the image preprocessing module performs feature extraction and segmentation processing on the input video image data stream, and then through the image registration module, several acquired The images are matched and superimposed, and then several acquired images are spliced ​​and fused through the image fusion module to form a panoramic image of the airport run-slip area; the object recognition module recognizes the moving objects on the panoramic image of the airport run-slip area, Moving objects are tracked. The invention realizes the panoramic monitoring of the slipping area of ​​the airport, can perform real-time identification, tracking and early warning, and improves the safety of the slipping area of ​​the airport.

A method for optimizing the layout of monitoring points for emergency monitoring of sudden air pollution accidents

The invention relates to an optimal layout method of monitoring points for emergency monitoring of sudden air pollution accidents, which belongs to the technical field of early warning and evaluation of environmental risks. The invention uses a pollutant diffusion model to determine the diffusion range and concentration distribution characteristics of pollutants after the accident, and grids the distribution range based on the distribution characteristics of environmentally sensitive points in the downwind direction; quantitatively handles geographical and environmental sensitivity through fuzzy evaluation theory According to the uncertainty among the factors affecting the distribution of emergency monitoring points such as source distribution, different grids are screened by combining post-optimization technology based on cluster analysis, and the location and quantity of emergency monitoring points are determined according to the amount of monitoring resources. The optimal distribution method quantitatively converts the uncertainties in the optimal distribution, characterizes the influence of different factors on the monitoring distribution, and makes up for the defect that the emergency monitoring distribution of sudden air pollution accidents can only refer to the monitoring specifications and historical work experience of conventional pollutants. .

A Crack Monitoring Device for Cement Pavement After an Earthquake

A monitoring device for cement pavement cracks after an earthquake, comprising a cracked pavement, a fixed plate on both sides of the crack, a support plate above the fixed plate, a strip groove on the side of the fixed plate and the support plate, and a space between the fixed plate and the corresponding support plate. The rotating shaft, one end of the fixed plate is connected to the limit plate, there are cross bars on both sides of the road surface, the distance sensor on the side of the limit plate, the elastic arc plate above the support plate, the elastic arc plate has a first through hole, and the first through hole is in the first through hole. There is a warning light, the opposite end of the support plate is connected to the lap plate, the lower side of the warning light is connected to the rechargeable battery, and there is a drainage device at the corresponding crack of the road surface. The invention utilizes the impact force, frictional force and pressure on the device during the driving of the vehicle to drive the left and right road surfaces to move closer to each other, so that the expansion speed of the crack can be slowed down during the occurrence of the earthquake, and the crack can also be repaired during the earthquake subsidence period. The service life of the damaged road surface, and the device can also drain the cracks to reduce the loss after the earthquake.
