What are the structural components and basic functions of the building intercom system?

Host: Can call and talk to extensions.

Extension: It can call the host, be called, intercom, monitor, open the electric lock and other functions.

Power box: A special device that supplies power to the system, and automatically supplies power to the system when the power fails.

Smart lock: to prevent strangers from entering the floor, guests can call the extension as long as they press any key of the host, and the host can press the extension unlock key to open the door for the guest.

Door closer: The door automatically closes when guests enter the floor.

The building intercom system is mainly composed of the main engine, extension, UPS power supply, electric lock and door closer.

The host is the core part of the control of the building intercom system, and the transmission signal and the electric lock control signal of each extension are controlled by the host.

The extension is a kind of walkie-talkie, which is generally intercom with the host, but now the intercom system of the building is cooperated with the host to form a set of internal first-class system, which can complete the first-class contact of individual users in the system.

The function of UPS power supply is mainly to keep the building intercom system from power loss. Under normal circumstances, it is in a state of charging. When there is a power failure, the UPS power supply is in the state of supplying power to the system.

The internal structure of the electronically controlled lock is mainly composed of an electromagnetic mechanism. The user can use the electromagnetic coil to energize by pressing the electric lock button on the extension, so that the electromagnetic mechanism can drive the connecting rod to operate, and the opening of the gate can be controlled.

The door closer is a special automatic door closing linkage mechanism. It has a regulator that can adjust the acceleration and force of action, which is convenient and flexible to use.

How it works. The door of the building is always locked to prevent non-residents from entering the building without permission, and the residents of the building can enter and exit the building freely with the key. When a guest visits, the guest needs to press the room number of the resident to be visited on the keyboard of the intercom host outside the building door to call the intercom extension of the resident to be visited.

The owner of the interviewed household conducts two-way or video communication with the visitor through the intercom device, and confirms the visitor's identity through the visitor's 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 electric lock on the entrance door of the building to open, so that visitors can enter the building. When visitors enter the building, the door is automatically locked.

The safety and security department of residential property management can monitor the working conditions of the security intercom system of each residential building in the community through the community security intercom management host. If the entrance door of the residential building is illegally opened, the security intercom host or line fails, the community security intercom management host will send an alarm signal, showing the content and location of the alarm.

The system can be used to communicate with each other between the property management department of the community and the residents or between the residents and the residents. For example, the property department notifies the residents to pay various fees, the residents notify the property management department to repair the residential facilities, and the residents call the police to the management of the community or the neighborhood for help in case of emergency.

Indoor unit, door host, server, and other fire linkage or smart home connection auxiliary components.

1. Call line: power control circuit.

2. Telephone line: call circuit.

3. Receiving line: intercom circuit.

5. Ground wire: circuit.

Visitors to enter the building, first press the user number button on the host of the anti-theft door, the ringing of the resident extension rings, the resident off-hook through the intercom system and ** system to confirm the visitor, and then press the button to make the circuit action on the host, the electronic lock of the anti-theft door is opened.

Inter-floor distributors, also known as floor platforms. The main functions are as follows:

Line protection. Communication signal isolation.

Provide power supply for indoor extensions.

Even if a household's extension fails, it will not affect the normal use of other users, nor will it affect the normal operation of the system.

In fact, it is the principle of a small program-controlled machine.

1. Calling function: the host can correctly select any extension, and can hear the ringback tone 2, call function: after calling, it can implement duplex calling, the voice is clear, and there is no ringing phenomenon 3. Electronically controlled unlocking function

On the extension, the electronic control unlocking function can be implemented 4, self-protection function: when the host encounters abnormal disassembly, the alarm is immediately generated 5, monitoring function: after the host and the extension are connected by the key, the image signal taken by the host camera can be obtained on the graded monitor, which is convenient for identifying visitors.

6. Night vision function: under the condition of normal installation, the host can identify visitors on the extension monitor at night.
