Abstract
The utility model relates to an integrated service digital network video talkback door bell, which is composed of a first extension set (1), a second extension set (2), a third extension set (3), a fourth extension set (4), a first overcurrent branch (5), a second overcurrent branch (6), a power supply inserting device (7), a power supply box (8), an exchanger (9), a management machine (10), a main machine (11), a networking device (12), a power supply box (13) and an electric lock (14). The integrated service digital network video talkback door bell is characterized in that the management machine is connected with the exchanger through a concentric line directly, the exchanger and the networking device are connected directly through the concentric line, the networking device is connected with the main machine through the concentric line directly, one end of the main machine is connected with the power supply box through the concentric line, and the other end of the main machine is connected with the power supply inserting device. The integrated service digital network video talkback door bell has the advantages of enabling construction, maintenance and networking to be simple, saving large amount of wire materials and construction cost, and simultaneously greatly improving reliability and anti-disturbance performance of the system.
Description
Technical field:
The utility model relates to a kind of Integrated Service Digital Network video intercom doorbell, refers specifically to a kind of Integrated Service Digital Network video doorbell that adopts single coaxial cable images, voice-and-data high-frequency carrier signal and power supply.
Background technology:
Along with improving constantly of living standard, people are also increasingly high to the requirement of doorbell, and the technological improvement of doorbell is also in constantly carrying out; Doorbell kind in the market is a lot, mainly contains Line Doorbell and wireless doorbell, and having between indoor set and the off-premises station of Line Doorbell is to link through data wire; Adopt a kind of analog signal to carry out message transmission; Need wiring during installation, not only bring difficulty, and influence the aesthetics of floor to installation and maintenance; Directly be connected between the indoor set of wireless doorbell and the off-premises station, but carry out work through the radio transmission signal, though overcoming the shortcoming that Line Doorbell is arranged, its antijamming capability is relatively poor, and the transfer of data accuracy is not high.The utility model provides kind Integrated Service Digital Network entryphone, can overcome the deficiency of above technology well.
The utility model content:
In order to solve the problem that exists in the above technical field, the utility model provides following technical solution.
2, like figure (1); The utility model is made up of extension set 1, extension set 22, extension set 33, extension set 44, overcurrent splitter 1, overcurrent splitter 26, power inserter 7, power supply box 8, switch 9, supervisor 10, main frame 11, networking device 12, power supply box 13 and electric lock 14; Directly link through concentric line like figure (5) supervisor and switch, through supervisor call out extension set, monitor host, by call extension, called out and carry out call record and inquire about by main frame; Directly link through concentric line like figure (4) switch and networking device, the RF signal is changed, become the RF signal to transmit conversion of signals such as audio frequency, video and data, and be connected with a plurality of networking devices through common splitter through switch; Directly link through concentric line like figure (3) networking device and main frame, the RF signal is carried out radio frequency output through the networking device; An end and power supply box like figure (1) main frame link through concentric line, and the other end and power inserter link, through main frame calling extension set and Call Management Center with change unlock code; , the RF signal is mixed with DC power supply through power inserter and indirect the linking of overcurrent splitter like figure (2) main frame, also power supply is provided for extension set through power inserter with extension set; Overcurrent splitter and extension set link through concentric line, and the overcurrent splitter can infinitely increase, and whenever increase an overcurrent splitter, just can increase the access of four extension sets.When this overcurrent splitter was exclusively used in networking, the networking line signal distributed and signal is carried out fixed attenuation.
The beneficial effect of the utility model is to utilize very ripe cable TV philosophy and technique; Signals such as the image of system, voice-and-data are transmitted through the mode of modulation and handle; Thereby reach the purpose that improves signal quality; System all adopts single coaxial cable images, voice-and-data high-frequency carrier signal and power supply, thereby makes construction, maintenance and networking become very simple, saves a large amount of wire rods and construction cost; Simultaneously, the reliability of system and antijamming capability are greatly improved.
