Description
Technical field
The present invention relates to communication base station, and in particular to a kind of method and device of monitoring communication base station and electric power power supply state；
Monitoring available for communication base station and electric power power supply state.
Background technology
With the establishment of steel tower company of China, how to reduce cost in being runed in base station is matter of utmost importance, wherein generating electricity into
This reduction is again the material items stood in the breach, and how to monitor causes generating expense empty by the hydro power generation for the generation that artificially rehearses
High the problem of, and by counting the problem of generating data cause inefficiency by hand, as the priority cases for being badly in need of solving instantly.According to
Authoritative institution estimates, and the annual false generating expense of steel tower reaches the 27.8% of total generating expense, that is, 36.3 hundred million yuan.
Traditional settling mode is that a hydro power generation monitoring modular is installed on mobile diesel engine, by detecting that oil machine is sent out
The presence or absence of electricity output voltage, generating start/stop time and generating duration, oil machine position (GPS location) is associated with base station rotating ring monitoring
The mains failure data of system, judge whether oil machine really generates electricity for base station accordingly, and all these measures are still easily artificial
Play tricks.Because civil power service entrance switch is easily artificially disconnected, false municipal power failure is caused, and can not be current in the monitoring of electricity consumption side
Power supply source belongs to civil power or generating, causes the leak that can be artificially faked.
The content of the invention
It is an object of the present invention to monitor communication base station and electric power there is provided one kind in view of the above-mentioned problems existing in the prior art
The method and device of power supply state；Monitoring available for communication base station and electric power power supply state.Avoid occurring false municipal power failure, with
And civil power or generating can not be belonged in the electricity consumption side current power supply source of monitoring, the problem of causing artificially to be faked.It is a kind of
The power supply source monitoring system of frequency jitter rate harmonic amplitude detection technology based on electric field induction Detection Techniques and civil power/generating
System.
The present invention can distinguish the device of civil power/generating, prevent from being replaced generating electricity with civil power, cause false charging；It can recognize
The device of invalid generating, charging is stopped after civil power is normal at once；The generating number of times of each base station can be effectively monitored, is generated electricity
The device of duration, is easy to check generating expense；Installed at the foot of the hill because the civil power for the base station having enters line side switch, some installations
In computer room, the scheme of 2 kinds of different monitoring civil powers is resulted in the need for；Effectively monitoring city's electricity condition, prevents that artificially disconnecting civil power enters
Line circuit on civil power inlet wire side line road, it is necessary to install one, and the electric field induction that can be bundled on civil power inlet wire side line road is popped one's head in；
Electric field induction probe must be able to the voltage range of effectively identification civil power, and civil power is identified as in below 85VAC for disarmed state, is surpassed
Identification civil power is effective status when crossing 100VAC；Electric field induction probe must be able to effectively prevent interference, particularly in line
It is high to being produced between the earth now close to the line powerful induction antenna super equivalent to one of base station when destroyed
Up to 60-300V voltage, interference is produced to probe, causes probe can not normally recognize the state of civil power；In order to avoid probe wire
Road is destroyed, it is necessary to monitor the connection line of probe, once occur destroyed sending alarm in time；By the result of city's pyroelectric monitor,
Remote server effectively is transferred to, one can be with the device of transmission of monitoring result；Can accurately, each power supply of complete detection base station
Source state, and power supply beginning and ending time, and the current power supply powered to base station equipment, effective monitoring is false to generate electricity and invalid hair
Electricity, reduces the operation cost of base station, realizes the programming count of generating number of times and generating duration, smoothly completes operator and for dimension
Between generating cost accounting, specification generation dimension unit generating behavior.

Civil power and the different of voltage fundamental/harmonic ratio generated electricity carry out discriminatory analysis, particular by preset time window (5-20 seconds), inspection
The frequency jitter rate and voltage fundamental/harmonic ratio of the input power of AC/DC Switching Power Supplies are surveyed, in frequency jitter rate and voltage base
When ripple/harmonic ratio is both less than predetermined threshold value, judgement is to belong to civil power, is both greater than in frequency jitter rate and voltage fundamental/harmonic ratio
During predetermined threshold value, judgement is to generate electricity；
City's electricity condition that the power supply source judge module is detected according to civil power inductive probe, and 48V voltage changes analysis mould
The accumulator battery voltage mutation status that block is detected, and the input of AC/DC Switching Power Supplies that 3 phase-voltage measurement modules are detected
Power supply (civil power/generating), judges currently to belong to civil power to the power supply that base station equipment is powered or generates electricity either battery
Group.
