In order to manage the entry and exit of various people in the building more effectively and safely, the property management company or management personnel can effectively control the entry of unused personnel, and can achieve this functional requirement by adopting reasonable control of the elevator. SD816 is a dedicated elevator controller for elevator control and integration in buildings. After using SD816 to transform the elevator button panel, all cardholders who use the elevator must first be authorized by the system administrator. When using elevators, different people have different authority assignments. Each person who enters the elevator can enter the designated area or floor with authorization, and can perform authorization management according to the timetable. Without authorization, it is impossible to enter the floors of the management area, and control the time period of important floors. Regardless of whether the controller is running offline or online, it can record a large amount of transaction data, so that all the elevator personnel entry and exit records can be found.
SD816 adopts imported fingerprint reader. Its fingerprint adopts the world’s top technology, and its algorithm and recognition technology are far ahead of the domestic counterparts’ fingerprint technology. Through the use of Stall elevator controller, it can run stably in any elevator. The Stall fingerprint elevator management system can run independently, even if the PC is turned off, the SD816 can be used normally, ensuring its stable and reliable control function, thereby improving the level of building management.
Chapter One Imported Fingerprint Elevator Management System Demand Analysis
The current actual situation and your system requirements are summarized as follows:
(1) Shared elevators need to be controlled.
(2) The highest floor of each elevator.
(3) Whether to strictly control the floors where personnel enter and exit.
Chapter 2 Design Objectives and Principles of Imported Fingerprint Elevator Management System
2.1 System design goals
The SDOOR fingerprint elevator management system is based on advanced computer technology, communication technology and fingerprint technology, which brings safe and convenient control to the use of elevators.
The specific goals are:
People with valid fingerprints can use elevators conveniently and safely.
Persons with valid fingerprints can only enter and exit authorized floors.
The elevator cannot be used without effective personnel.
It does not affect the operation of the original elevator system and ensures the safety of the entire system.
Managers can conveniently set up personnel’s access to floors and view personnel’s access records.
Economical and reasonable operating costs.
2.2 System design principles
Advancement: adopt current advanced and mature technology and equipment;
Safety: Does not affect the operation of the original elevator system, and guarantees its safety.
Practicability: Reasonable configuration and selection of appropriate product models make the entire system stable, reliable and cost-effective.
Convenience: A complete management system, clear software operation, and convenient use of the system by both managers and users.
The principle of scalability and ease of maintenance.
Openness: In order to ensure the coordinated operation of the products of various suppliers, while taking into account the long-term interests of investors, the system must be an open system and be implemented in conjunction with relevant international standards or industrial standards.
Chapter 3 Imported Fingerprint Elevator Management System Solution and Technical Description
3.1 System overview
The purpose of the SDOOR fingerprint elevator management system is to control the use of elevators, and its function is actually a special solution for special occasions of the access control system.
The system integrates inductive fingerprint technology, computer technology and communication technology. The SDOOR fingerprint elevator management system solution is divided into two types according to the degree of control and the use process of the keys: simple type and swiping button type.
3.2 Basic functions and features of the system
Installing the control host and card reader in the elevator can strictly control the number of floors that people enter, that is, after fingerprint verification, pressing the corresponding authorized floor button will be effective, and the fingerprint button will not be effective unless the fingerprint is verified.
Basic functions and features:
Can strictly control everyone’s access to the floor.
Using the original American built-in battery chip, the elevator use record and clock will never be lost.
Can be used offline or online.
The software is easy to operate and can monitor the elevator usage in real time.
Password or fingerprint system is optional.
You can set the working status of the elevator, that is, the elevator can manage the floor by the controller; you can also disconnect the controller from the elevator floor according to the needs of the customer, and the elevator equipment can control it by itself.
SDOOR fingerprint elevator management system is unique:
For different occasions and needs, provide the best and most economical solutions.
The system is flexible and expandable.
It can monitor the elevator usage in real time.
3.3 System structure
The system is managed by a computer, and the serial port of the computer is connected to each control host through the communication converter (Rs232/Rs485), and then the control host is connected to the buttons in the elevator.
