Abstract
The utility model provides a kind of maritime affairs trunk desk, including base station, the base station includes the host and backup host that harbour is arranged in, and is mounted on the antenna of harbour high-lager building eminence, the antenna is two omnidirectional antennas, is connect respectively with host and backup host by feeder line；The channel device of the host and backup host has 25W adjustable power amplifier, frequency range: 132-174MHz；The interchanger of the host and backup host is connected using digital speech interchanger with channel device.The utility model provides a kind of maritime affairs trunk desk, realizes the serial communication being distributed between each anchor pyridine place.
Description
Technical field
The utility model relates to maritime affairs trunk desk fields.
Background technique
Container ship is long from the distance between the anchorage position at harbour because anchorage position changes, and it is public that some is even up to 30
In, cause hand transceiver that can not communicate between different anchoring ground.
Utility model content
The utility model at present due in harbour the distance between container ship it is remote, cannot be realized using intercom
Communication of the anchor pyridine between the container ship everywhere of harbour, provides a kind of maritime affairs trunk desk, realization be distributed in each anchor pyridine place it
Between serial communication.
In order to solve the above technical problems, the technical solution adopted by the present invention is that: a kind of maritime affairs trunk desk, including base station,
The base station includes the host and backup host that harbour is arranged in, and is mounted on the antenna of harbour high-lager building eminence, described
Antenna be two omnidirectional antennas, connect respectively with host and backup host by feeder line；The host and backup host
Channel device has 25W adjustable power amplifier, frequency range: 132-174MHz；The interchanger of the host and backup host
It is connected using digital speech interchanger with channel device.
The utility model provides a kind of maritime affairs trunk desk, realizes that the communication terminal being distributed between each anchor pyridine place is logical
Letter.
Further, channel device described in above-mentioned maritime affairs trunk desk selects MOTOROLA M8268 modulus intercom；Institute
The digital speech interchanger stated is that the DCS-5020 digital speech that Xian Chuan company in the U.S. produces dispatches system.
Below with reference to drawings and examples, the utility model is described in detail.
Detailed description of the invention
Attached drawing 1 is the structural block diagram of the utility model trunk desk.
Specific embodiment
The present embodiment is one kind one main one for twin-engined trunk desk, is a kind of 73 channel either simplex trunk desk of harbour maritime affairs.
As shown in Figure 1, including base station, base station includes the host and backup host that harbour is arranged in, and it is high to be mounted on harbour high-lager building
The antenna at place, antenna are two omnidirectional antennas, are connect respectively with host and backup host by feeder line；Host and backup host
Channel device has 25W adjustable power amplifier, frequency range: 132-174MHz；Host and the interchanger of backup host use number
Word voice exchange is connected with channel device.
In the present embodiment, maritime affairs VHF communication is a set of conventional ship-to-shore wireless communication system, uses international standard VHF frequency
Section waits for one VHF trunk desk of channel setup for 73CH, and host is mounted in the 25 buildings communication in salt pan International Building, by day
Line is connected to 26 buildings balconies, and trunk desk works in such a way that main standby (manual) 24 is small.This system believes maritime affairs international standard 73
Road, simulation radio station peculiar to vessel, land intercom, land Vehicle mounted station realize telecommunication；Realize harbour vessel scheduling intercom and
The signal covering of water surface steamer, harbour intercom；Existing intercommunication machine equipment is not replaced, does not change vessel and harbour to reach
Telecommunication between intercom
Trunk desk passes through the transceiver interface that feeder line is connected to channel device with 2 omnidirectional antennas respectively, customizes two sets of antenna branch
Frame is fixed on balcony brandreth and installs.Antenna is both needed to arrester, carries out lightning protection to equipment.1/2 " main feeder, connecting line
Cable, various connector and other installation attachmentes are all made of the product of Suzhou An get Lu or ATM, and antenna is customization antenna or brand antenna
Mating channel device covers signal to new anchorage position and harbour range.
The 25W adjustable power amplifier of trunk desk channel device intelligent control；It is able to satisfy harbour non-stop run in 24 hours, is believed
Road unit frequency range: 132-174MHz；Channel is listened using 73 channels as keeping in base station；Building berth does not make any change, YICT intercom
3-73 frequency more improves as 161.275MHZ；It is installed using cabinet；Alternating current 220V is selected in channel device power supply；Adaptive temperature range :-
30 DEG C Dao+60 DEG C；It is compact-sized, save space；Power supply need to use highly reliable and stable AC power source, can be in Width funtion and frequency
It works within the scope of rate.
Trunk desk is by power supply, channel device, digital speech interchanger and antenna feeder group；Efficiently solve marine building berth and land
Communication between platform expands communication distance.
In the present embodiment, channel device selects MOTOROLA M8268 modulus intercom, may be implemented from analog to number
Transition.
Interchanger first creates the DCS-5020 digital speech scheduling system of (ZETRON) company production using the U.S., which passes through
It wirelessly sends connection function that can connect different phone groups, and two different group connections is made to form a big phone group,
And make one of group (such as 73 channels) can cover new anchorage by setting up antenna transmission system, and another group (such as:
73A channel) harbour operating area can be covered, the wireless talkback communication between dock area and new anchorage can be realized.
