The intelligent community system will be the main introduction object of the following content. Through this article, the editor hopes that everyone can have an understanding and understanding of its relevant situation and information. The detailed content is as follows.
1. Building automation system
The building automation system is composed of a management host, executing agencies, various sensors, and transmission cables, mainly used to achieve automatic control of mechanical and electrical equipment in buildings or residential areas. The building automation system is centered around computer control and management, using various sensors for detection, and utilizing various corresponding executing agencies to centrally control and manage various equipment such as power supply systems, air conditioning systems, lighting, elevators, water supply and drainage, sprinkler systems, irrigation, etc. in the area. Implementing decentralized control and centralized management plays a role in energy conservation, reducing maintenance personnel, and extending the service life of equipment.
2. Program controlled switching system
The digital program-controlled switch adopts the most advanced microprocessor as the control core, with a fully decentralized control method, modular programming, and the selection of large-scale TTL and CMOS digital integrated circuits, making the entire machine highly stable and reliable. Fully functional, low power consumption, small size, and light weight. In terms of interface configuration, it has the advantages of flexible interface configuration and convenient networking. The interface configuration is roughly divided into two parts, namely the inner line part and the outer line part. The internal line includes ordinary user interfaces, 2B+D digital user loops, 2.048Mbit/sPCM interfaces, and U trunk interfaces.
The digital program controlled switch system is composed of various dispersed functional modules. Each module has its own processor, and each module processor is at the same level in the entire system, which can relatively independently complete some functions. The exchange network (SNM) and message distribution network (MDM) that complete inter module communication and session exchange form an interconnection network, which is the core part of the entire system; Each module processor transmits various information (including call, billing, and maintenance information) through the system’s message distribution network MDM and SNM are the gathering and distributing places for various messages in the system, which complete the collaboration between modules through message distribution networks, thereby achieving the coordination of the entire system; The exchange of voice messages between peripheral modules is completed through the exchange network module, and the connection of the session is completed. The peripheral modules can handle some functions relatively independently, and the peripheral exchange module can handle calls independently. When the call involves other modules, the message allocation module can send a request for cooperation to the relevant modules; If new functions need to be added, only new functional modules need to be added, and the corresponding switching path is provided by SNM. The interface of this module can be easily accessed as long as it meets the interface standards between modules, achieving the goal of adding new functions. However, the entire system structure does not need to be adjusted The overall structure of the multi module system of the programmable digital switch: the operation and maintenance module (OMM), message distribution module (MDM), and switching network (SNM) form the central module, which is the exchange place for the digital programmable switch system’s sessions and messages; The capacity of the switching network has been expanded through SNM, communication between multiple MPs has been simplified through MDM, and centralized maintenance functions of the system have been achieved through OMM.
3. Visual intercom networking system
The building intercom system consists of an intercom host, an indoor extension, a management host, and a transmission cable. Set up a visual intercom in the residential area, where the homeowner can intuitively understand the visitor’s situation and control the door lock to open. Each intercom host in the building is connected to the security center management host, and the security center can keep track of residents’ distress signals at any time. After years of development, building intercom products have evolved from having only a single intercom function in the past to today’s system that integrates multiple functions such as visual intercom, access control, home security, and information announcement. Its functions are as follows: the building intercom system should be able to achieve tripartite communication and unlocking functions for visitors, residents, and administrators; The control host has anti damage alarm function; Residents can directly press the password on the unit entrance machine to open the door electric lock; When someone illegally tampers with or damages the unit entrance machine, an alarm message can be issued; Infrared CCD camera and night fill measures enable clear images to be obtained at night; The indoor unit can clearly display visitors and outdoor conditions; By connecting the community information network with the central computer, intelligent and centralized management of the community can be achieved; The high-end intercom system also has various alarm expansion functions, which can be integrated with the alarm system.
The door of the building is always in a locked state to prevent unauthorized entry by non residents. Residents of the building can freely enter and exit the building with keys. When a guest visits, they need to press the room number of the desired resident on the intercom host keyboard outside the building and call the intercom extension of the desired resident. The owner of the visited resident conducts two-way or visual communication with the visitor through intercom devices, and confirms the visitor’s identity through their voice or image. After confirming that visitors can be allowed to enter, the owner of the resident uses the unlock button on the intercom extension to control the electronic lock on the entrance door of the building to open, and visitors can only enter the building. After visitors enter the building, the door automatically locks.
The security department of residential property management can monitor the operation of the security intercom system in various residential buildings within the community through the community security intercom management host. If the entrance door of a residential building is illegally opened, or the security intercom host or circuit malfunctions, the community security intercom management host will issue an alarm signal, display the content and location of the alarm. The property management department of the community can use this system to communicate with residents or between residents. For example, the property management department notifies residents to pay various fees, residents notify the property management department to repair residential facilities, and residents report to the management personnel or neighbors of the community for help in emergency situations.
4. Home security system
The home anti-theft alarm system is composed of a security center management host, a security alarm, various sensors, and transmission cables. The main entry points for home theft are doors and windows, and sensors are mainly used to protect important locations and areas of the home. High quality sensors can replace traditional steel plate anti-theft nets in homes, allowing homeowners to live in a safer and more comfortable environment without the feeling of being trapped. Burglar alarm: Install a passive infrared detector in each room of the resident. When an illegal intruder is detected, the alarm signal is triggered and transmitted to the intelligent controller of the resident. The controller emits an audible and visual alarm and transmits the signal to the intelligent control center. The electronic map of the control center immediately displays which type of alarm occurred in which building, which household, and which room, and immediately notifies the security personnel to handle it on site. Gas leakage alarm: Install a gas leakage detector in the kitchen and toilet, with two installation heights: when the burned gas (such as carbon monoxide) is lighter than air, install it 0.3 meters from the ceiling; When the gas burned (such as propane and butane) is heavier than air, install it at a distance of 0.3 meters from the ground; When there is a gas leak, an alarm is triggered and the pipeline valve is automatically closed. At the same time, the intelligent controller and control center are notified, and the alarm method and transmission path are the same as the infrared anti-theft alarm. Fire alarm: Install a temperature or smoke detector in the living room. When a fire occurs in the resident, the detector triggers an alarm and notifies the intelligent controller and control center. The alarm method and signal transmission path are the same as infrared anti-theft detection. Emergency help system: When a thief appears, there is a patient at home or other needs help, press the emergency help button, the signal is transmitted to the control center, and the control center immediately sends people to the scene.https://www.stoneitech.com/
