Description

The invention relates to methods of remote monitoring and can be used to ensure real-time public safety, to detect all types of offenses, including in emergency situations, at residential and administrative buildings such as elevator cabins.

There is a known method of video monitoring, including the use of stationary analog video cameras that perceive and transmit the image of the observed territory, a rotary digital video camera that perceives and transmits an image of a part of the observed territory or an object in it, a switch and a server (EA 200802188 A1, 30.04.2010).

The disadvantages of this analogue include insufficiently high performance of the main elements of the system, which reduces the efficiency of processing the events by the operator.

The objective of the invention is to develop an effective method for remote monitoring of elevator cars with the elimination of the above disadvantages.

The technical result is the speed and continuity of the transmission rate of signals from sensors, video cameras, display call buttons, availability on all types of devices and the ability to connect to the system from anywhere in the world.

This is achieved by the fact that according to the method of remote monitoring of elevator cars according to the invention, a display with a power cable and a USB cable is installed in the elevator car, then hall sensors and magnetic tags on each floor are installed in the space between the car doors and the floor doors, on the display microcomputer with an application with a media interface is installed using a flash drive, signals from sensors, video cameras and buttons for calling the display manager are read by means of the said application with a media interface with the possibility of further uploading them to the server computer via the web interface, videos are downloaded to the server computer, and then then they are loaded and played on displays through a web interface with the ability to identify them using a unique ID number.

By means of a flash drive of a microcomputer, video signals are recorded with the possibility of their further uploading to a computer via a web interface. The display power cable is connected to the power supply on the roof of the elevator car, and the USB cable is connected to the 4g / LTE receiver.

The claimed invention can technically be divided into three main components: front-end display, smoke detector, dispatcher call button, camera, microcomputer;

server part - a collection of information and the production of analytical calculations, reporting;

web interface - displaying data on the status of elevators, graphs, reports, loading and managing content.

The front end is a vandal-proof display protected by impact-resistant glass, controlled by a Linux-based microcomputer with built-in sensors, a camera and a dispatcher call button. The microcomputer is preinstalled with an application with a media interface.

The media interface downloads and plays videos uploaded to the server, while identifying videos intended for a given area using a unique ID number. The application also reads data from sensors and detects pressing the operator call button.

The operator call button, when pressed, sends an SMS signal to the elevator and the assigned KSK employee. If, after 10 minutes, the button is pressed again, then a telephone connection will be established with the dispatcher of the Main Operations Control Center (city center of operational control) and the dispatcher will take a further decision up to calling the Ministry of Emergencies.

The surveillance camera is installed in the display housing and has a wide viewing angle of 140 °. Video recording is made to a microcomputer flash drive and can be remotely uploaded to any computer via the web interface.

The drawing shows a schematic diagram of the operation of the method for remote monitoring of elevator cabins.

Anti-vandal display production

The display case is made of an aluminum alloy frame and is covered with a steel cover at the back and covered with a 5mm impact-resistant knee glass.

The displays are transferred for retrofitting to the assembly shop for installation in a microcomputer case, sensors, a camera and an operator call button.

First of all, the Raspberry Pi model 3b microcomputer is installed, before that a flash drive with a Linux OS image with a preinstalled application with a media interface is installed on the microcomputer.

A power supply unit is installed that converts alternating current 220 V to 5 and 12 V, respectively, necessary to power the components. Then the smoke detector, button and camera are mounted, cables are pulled.

The complete display is transferred to the laboratory and installed on a test bench, where the operation of all systems is checked. Then the display is transferred to the assembly team, which assembles the display in the presence of KSK employees in the elevator car.

Holes are drilled in the elevator car for mounting the mount and one hole for power and USB cable. Then the display is installed on the mount. Hall sensors and magnetic tags are installed in the space between the car doors and floor doors on each floor to determine the floor and the position of the elevator in the shaft.

The removed power cable is connected to the network on the roof of the elevator car, and a 4g / LTE receiver is also installed and a USB cable is connected to it to transfer data to the elevator car.

In some cases, it is necessary to install a cellular signal amplifier on the roof of the building directly above the elevator shaft, directed towards the receiver.

The server part of the project is built on the basis of PHP and is an analytical center, which accumulates and analyzes data collected from sensors, as well as storing videos.

The principle of separating videos is built in the form of folders with files for a specific area, which are edited by an operator using a web interface from the company's office. The rollers can be downloaded at any time, and the display in the elevator car downloads the video from the server once an hour. This feature allows you to flexibly and promptly display advertising videos.

Another server subsystem is the text track (creeping line displayed on the display), it is built on SQL and connects to the emergency message distribution system. That is, if the city sends information, for example, about a drop in temperature and the cancellation of classes in schools, the system will display this information on displays, and through the web interface, employees of KSK houses in which the displays are installed can show their ads to residents.

The project web interface presents a page for managing displays and displaying information about the status of the elevators used in the project. The obvious advantage of a web interface over a specialized program is its availability on all types of devices and the ability to connect to the system from anywhere in the world. The connection to the web interface is made by login and password. Each user of the system has his own level of access and certain capabilities. Access levels are regulated by the system administrator and can be changed as needed.

Access levels are divided into several categories:

administrator - full access rights;

operator - loading and managing videos;

dispatcher (employee of city services) - information about the state of elevators, access to reporting, the ability to call the elevator car;

security dispatcher (city services and the Department of Internal Affairs) - information on the status of elevators, access to reporting, the ability to call the elevator car, access to video recordings from surveillance cameras;

KSK employee - information about the status of elevators, access to reporting, loading messages into the running line (only for KSK houses).
