Abstract
The utility model provides a kind of antenna feeder monitoring device, including the uplink interference suppressor being connected between signal generator and antenna, and uplink interference suppressor is sent to before the signal of antenna is carried out to signal generator to coupling and and reverse coupled；Described uplink interference suppressor is provided with detection circuit, and detection circuit is connected with control unit by RS485 interfaces, and control unit is connected to upper main frame by Ethernet.The utility model provides some signals transmitting equipment without antenna feeder monitoring function antenna feeder monitoring functions, and the antenna feeder standing wave of real-time monitoring signals transmitting equipment when power and is alerted, and function will not fail as signal launches the failure of equipment.
Description
Technical field
The utility model is related to GSM-R wireless mobile communications field, specifically a kind of antenna feeder monitoring device.
Background technology
In current GSM-R mobile radio systems, to the signals such as base station, repeater launch equipment power detection and
The detection of antenna feeder standing-wave ratio is mainly carried out in itself by equipment, and some equipment have no this function；When equipment breaks down in itself, work(
Rate is monitored and failure also occurs in antenna feeder standing-wave ratio detection function, and failure can not be reported to Surveillance center in time.
The reason for this problem occur is the power detection and antenna feeder standing-wave ratio for launching signals such as base station, repeaters equipment
Detection is mainly carried out in itself by equipment, and antenna feeder monitoring is carried out to equipment without external equipment.
Utility model content
The utility model is in order to solve problem of the prior art there is provided a kind of antenna feeder monitoring device, to some without day
The signal transmitting equipment for presenting monitoring function provides antenna feeder monitoring function, the antenna feeder standing wave of real-time monitoring signals transmitting equipment when work(
Rate is simultaneously alerted, and function will not fail as signal launches the failure of equipment.
The utility model includes the uplink interference suppressor being connected between signal generator and antenna, uplink interference suppressor
Signal generator is sent to before the signal of antenna is carried out to coupling and and reverse coupled；Described uplink interference suppressor is provided with
Circuit is detected, detection circuit is connected with control unit by RS485 interfaces, and control unit is connected to upper master by Ethernet
Machine.
Further improve, power module is provided with described control unit, power module is control unit and detection electricity
Road powers.
The utility model beneficial effect is：
1st, antenna feeder monitoring function is provided to some signal transmitting equipment without antenna feeder monitoring function；
2nd, the antenna feeder standing wave of real-time monitoring signals transmitting equipment when power and is alerted（The alarm of input underpower, antenna feeder are stayed
Bob is alerted）；
3rd, function is achieved independently of signal transmitting equipment, and function will not fail as signal launches the failure of equipment.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
The utility model structure as shown in figure 1, the uplink interference suppressor including being connected between signal generator and antenna,
Uplink interference suppressor is sent to before the signal of antenna is carried out to signal generator to coupling and and reverse coupled；Described is up dry
Disturb suppressor and be provided with detection circuit, detection circuit is connected with control unit by RS485 interfaces, and control unit passes through Ethernet
It is connected to upper main frame.
Further improve, power module is provided with described control unit, power module is control unit and detection electricity
Road powers.
Operation principle of the present utility model is：Uplink interference suppressor is added between signal generator and antenna, to hair
Penetrate before power is carried out to coupling and reverse coupled, power is detected with detection circuit, and calculate antenna feeder standing-wave ratio, pass through
Data are reported to Surveillance center by RS485 buses by data transfer to monitoring host computer by monitoring host computer by Ethernet.
The utility model concrete application approach is a lot, and described above is only preferred embodiment of the present utility model, should
Point out, for those skilled in the art, on the premise of the utility model principle is not departed from, can also make
Go out some improvement, these improvement also should be regarded as protection domain of the present utility model.
