Description
Technical field
The present invention relates to remote conveying electric systems, and in particular to carries the remote power-feeding circuit system of detection circuit.
Background technology
Remote power system refer in long-distance wire communication, using cable or optical cable electric energy from end station or someone
It is transported to unmanned station after station, is the system of unattended relay station's power supply, with the development of science and technology to the requirement of remote power system
Higher and higher, the requirement to its stability and transmission range is higher and higher.
The major programme that the prior art extends power supply distance is divided into three aspects：Supply voltage makes up in transmission process
Voltage loss；Load power consumption is reduced, power requirement is reduced；Overstriking cable cross-sections accumulate, and reduce cable transmission loss.By the above way
Although diameter processing can largely play the role of extend power supply distance, due to certain special industries (such as coal mine) to power
Power supply has secure context consideration, and supply voltage is severely limited, and the simple difficulty for improving supply voltage is high.Due to industrial
Cable is expensive, and there is also the high problems of construction cost for overstriking cable diameter.
Invention content
Present invention aims at the remote power-feeding circuit system with detection circuit is provided, end-equipment is solved because supplying
The problem of the problems such as electric deficiency leads to not booting, frequently restarts.
The present invention is achieved through the following technical solutions：
Remote power-feeding circuit system with detection circuit, including main power source, main functional modules, secondary function module
And distributor circuit, the main power source connection main functional modules and secondary function module, the distributor circuit are arranged in main power source
Between secondary function module；The distributor circuit includes chip TPS62050, power supply quality detection circuit and power supply distribution electricity
Road, the power supply quality detection circuit are connected to chip TPS62050 pins LBI, and the power supply distributor circuit is linked at chip
The pin EN of TPS62050.
Corn module of the present invention provides electric energy with secondary function module by main power source.When remote power-feeding, if
There are instantaneous or prolonged electricity shortage situation, main power source will be not enough to support rear end demand due to front-end power, will be forced
Phenomena such as reducing output voltage, rear end corn module is caused to restart with secondary function module.When addition is for electro-detection
After circuit, changing circuit has the function of power supply quality detection and power supply distribution, when detecting electricity shortage, limits immediately secondary
Function module is powered, and plays the role of ensureing corn module steady operation, solves end-equipment because electricity shortage causes
The problem of the problems such as cannot be started up, frequently restarting.
Further, the switching circuit that the power supply distributor circuit is made of triode Q9 and triode Q11.Institute
Power supply distributor circuit is stated when input low level, by the interaction between triode Q9 and Q11, completes the work(of switch
Energy.
Further, input terminal setting the capacitance C, the capacitance C of the microcontroller are also associated with variable resistance.Capacitance is gone
Except the exchange in input microcontroller electric current, resistance can control the size of current of input microcontroller, while play protection microcontroller
Effect.
Further, further include alarm, the alarm connection is for power detection circuit.The alarm is used for failure report
It is alert, when detecting low level or unstable level for power detection circuit, alarm electric current is inputted, alarm prompts failure report
It is alert.
Compared with prior art, the present invention having the following advantages and advantages：
1, the present invention carries the remote power-feeding circuit system of detection circuit, solves end-equipment because electricity shortage causes
The problems such as cannot be started up, frequently restarting；
2, the present invention carries the remote power-feeding circuit system of detection circuit, and Core Feature is protected；
3, the present invention carries the remote power-feeding circuit system of detection circuit, and alarm is timely, stable structure.
Description of the drawings
Attached drawing described herein is used for providing further understanding the embodiment of the present invention, constitutes one of the application
Point, do not constitute the restriction to the embodiment of the present invention.In the accompanying drawings：
Fig. 1 is electrical block diagram of the present invention；
Fig. 2 is the preferential power supply plan power supply structure block diagram of the present invention.
Specific implementation mode
To make the objectives, technical solutions, and advantages of the present invention clearer, with reference to embodiment and attached drawing, to this
Invention is described in further detail, and exemplary embodiment of the invention and its explanation are only used for explaining the present invention, do not make
For limitation of the invention.
Embodiment
As shown in Fig. 2, the present invention carries the remote power-feeding circuit system of detection circuit, including main power source, major function
Module, secondary function module and distributor circuit, the main power source connection main functional modules and secondary function module, the distribution
Circuit is arranged between main power source and secondary function module；The distributor circuit includes chip TPS62050, power supply quality detection
Circuit and power supply distributor circuit, the power supply quality detection circuit are connected to chip TPS62050 pins LBI, the power supply distribution
Circuit is linked at the pin EN of chip TPS62050, and the power supply distributor circuit is made of triode Q9 and triode Q11
One switching circuit, input terminal setting the capacitance C, the capacitance C of the microcontroller are also associated with variable load, further include alarm
Device, the alarm connection is for power detection circuit.
As shown in Fig. 2, " corn module " provides electric energy with " secondary function module " by " main power source ".When remote
When power supply, if there are instantaneous or prolonged electricity shortage situation, main power source will be not enough to support rear end due to front-end power to be needed
Phenomena such as asking, being forced to reduce output voltage, rear end " corn module " is caused with " secondary function module " to restart.When
After " detection circuit " is added, changing circuit has the function of power supply quality detection and power supply distribution, when detecting electricity shortage, stands
That is limitation " secondary function module " power supply is played the role of ensureing " corn module " steady operation.
