The system integrates multiple functions such as access control management and elevator control. In the future, it can expand the functions of parking lot management, alarm management and stored value consumption. It is a cost-optimized solution.
The modular design of the system makes it easy to tailor the project according to the needs of the project to ensure the full use of system resources. At the same time, it is very convenient for users to expand system functions and expand system management in the future.
The system can manage the partition according to the customer's management settings, and conveniently realize the security management functions such as arming and disarming of each partition. The system can draw a plan according to the structure of the building, and can easily realize the functions of opening, closing, fortifying and disarming with a mouse click. The daily operation and management of the system is simple and convenient.
The system network is designed with network isolation function. When there is breakage in a certain part of the network cable, the system can continue to work and issue an alarm message, indicating that it should be repaired. Network isolation also increases the ability of system cables to withstand lightning and other signal noise.
The system is designed with automatic alarm functions such as low voltage and blown fuse. Users can monitor the security of the system itself at any time.
Each component of the system is designed and configured with a backup battery. Suddenly, the system can work normally for more than 4 hours, and the safety of the system is guaranteed from the power supply design.
The system RS485 network adopts the communication method of active transmission (interrupt request) and polling (Polling), which avoids the disadvantages of the low efficiency of the traditional RS485 network using only the polling method, and greatly improves the communication speed and efficiency of the system.
The system has designed a powerful main control module. The system does not need to manage the host to continuously boot, and can easily implement access control functions such as interlock (Interlock) and anti-passive (Anti-Passback).
The system adopts the advanced inductive smart card technology of the 1990s, with 1K bytes of storage capacity, and can be extended to realize the e-wallet function in the future, in line with the most advanced international standards for data security, safe and reliable.
The inductive smart card configured by the system can complete the card reading without physical contact, and can be used for plastic sealing, and the service life can reach more than 10 years. The logo of the apartment can be printed on the card surface, which is beneficial to the user to enhance the business image.
Second, the elevator intelligent control design concept According to the user's initial requirements for elevator intelligent control management, based on the principle of convenient use, comprehensive functions, safety and reliability, and strict management, design a computer intelligent system suitable for high-end apartments. Each user will hold a proximity card, such as a credit card size, and operate the elevator in accordance with the authorization obtained. The central management computer records all system events, configures the relevant management software to perform record query according to management requirements and automatically generate various reports.
The installation of an inductive card reader, a card reading module and a function expansion module in the elevator car constitutes an elevator control unit. After the cardholder reads the card in the elevator, the system allows the cardholder to reach the authorized access floor according to the prior setting. If the cardholder operates an unauthorised floor button, the elevator will not react. Non-cardholders cannot operate the elevator.
The control of the elevator can be set to achieve different management according to different time periods. For example, during a certain period of time, the operation of a certain floor elevator can be left uncontrolled, or the general cardholder can be authorized to enter more floors; in a certain period of time, only the cardholder is allowed to enter the designated floor according to the authorization.
The control of the elevator can also be controlled in conjunction with other subsystems. In the case of an emergency (such as a fire alarm), the system removes the control of the elevator; on important floors, the elevator and a door are set to the "Interlock" state. In the elevator, emergency alarm devices can also be installed. In case of passive holding, unexpected events, etc., the emergency button is used to realize the police.
If there are visitors, we can design the following two types:
A. Temporary cards for entering and leaving the floors are set up at the security department. The guests visit, through the video intercom, and the identity of the visitors is confirmed by the residents. The security card is issued by the security guard and the elevator is sent in and out.
B. Connect the video intercom system to the main control system of the elevator, install a button at the household, visit the guest, and use the video intercom to confirm the identity of the visitor and press the button to enter the tenant floor.
