Description
Technical field
The utility model belongs to DC power supply monitor, and in particular to arrives a kind of direct current comprehensive state monitoring device.
Background technique
With the raising of automation of transformation substations degree, the requirement to direct current operative power source is also higher and higher, but DC power supply
Monitoring device also rest on the state before the more than ten years, there is no substantive raisings, since human operational error causes seriously
The case where consequence, also happens occasionally, and since direct-current supervision reaction speed is slow, record event item number, content are limited, for accident
Ex-post analysis causes difficulty.
New industry, national standard also update not in time to be executed, direct-current supervision 0.5s general to the response time of intake,
Actually many monitoring device 1s cannot reach, slower to the sound shadow of the analog quantitys such as voltage, electric current, and record data are also few,
The numerical value of most multipotency record more in limited time, these are unfavorable for crash analysis, and early warning cannot find the problem in time well, occur
Mass efficient data cannot be provided after accident and carry out accident analysis.
Direct current system is opened without configuration anti-misoperation apparatus, such as the connection of charger switch, battery disconnector, bus
Close and supply power with double circuit switch etc., since direct-current supervision may be to these monitoring switch, or does not monitor all, or have monitoring
But to the not set warning function of incorrect state, these are the hidden danger of system.
Direct-current supervision is mostly inaccurate without time adjustment function or clock synchronization, records without unified format, cannot export,
So direct-current supervision be formed by record file have no idea using.
Utility model content
For overcome the deficiencies in the prior art, it adapts to reality to need, the utility model designs a kind of perfect in shape and function and each
The direct current comprehensive state monitoring device of equal energy reliability service under kind mal-condition.
In order to solve the above problem, the utility model uses a kind of following technical scheme: direct current comprehensive state monitoring device, it
Including main screen monitoring display module, main screen monitoring host, split screen monitoring display module and split screen data acquisition module, the master
Shield monitoring display module and connect main screen monitor display, split screen monitoring display module connects split screen monitor display, point
Shield monitoring display module and is equipped with 3 road Analog input mModules and 24 tunnel intake input modules, main screen monitor display and split screen
Monitor display is respectively equipped with communication port, and main screen monitor display is connected with main screen monitoring host, and the main screen monitors host
Equipped with 8 road Analog input mModules and 16 way switch amount input modules, split screen monitor display and split screen data acquisition module phase
Even.
Compared with the existing technology, the technical effect of the utility model is that the utility model provides a kind of comprehensive shape of direct current
State monitoring device realizes the judgement of recording entry condition and data storage, and storing data double copies protect data not lose reliably,
And it can be shared with former direct current monitoring device.
Detailed description of the invention
Fig. 1 is each module connected mode schematic diagram of the utility model；
Fig. 2 is the operation principle schematic diagram of the utility model；
Specific embodiment
As shown in Figs. 1-2, a kind of direct current comprehensive state monitoring device, it includes main screen monitoring display module, main screen monitoring
Host, split screen monitoring display module and split screen data acquisition module, main screen monitoring display module connect main screen monitor display, point
Shield monitoring display module and connect split screen monitor display, main screen monitor display and split screen monitor display are respectively equipped with communication
Mouthful, main screen monitor display is connected with main screen monitoring host, and split screen monitor display is connected with split screen data acquisition module.
Main screen monitors host and is equipped with 8 road Analog input mModules and 16 way switch amount input modules.
8 road Analog input mModule accumulation cell voltages, battery current, battery temp, busbar voltage, bus anode
The analog quantitys such as voltage-to-ground, bus cathode voltage-to-ground, charging voltage, charger electric current.
16 way switch amount input modules can fuse failure, be set as charger switch, battery such as keeps apart at the switching values.
Split screen monitoring display module is equipped with 3 road Analog input mModules and 24 tunnel intake input modules.
3 road Analog input mModules are set as connecing busbar voltage, bus anode voltage-to-ground, bus cathode voltage-to-ground etc..
24 tunnel intake input modules are set as connecing feeder switch state contact, or when switch is more can cascade multiple moulds
Block.
Main screen monitor display and split screen monitor display are all made of large screen touch screen LCD, and main screen monitoring is aobvious
Show device and split screen monitor display using same hardware, distinct program will also realize that limit value is set other than realizing display function
It is fixed, switching logic setting etc..
Backup power source is arranged in the recording part of the direct current comprehensive state monitoring device, when external power supply disappears, the present apparatus
It can still continue to run, guarantee to record DC system fault complete.
The direct current comprehensive state monitoring device voltage signal has been directly accessed to the system sample, and current signal uses system first wife point
Device is flowed, is shared with former direct current monitoring device, does not need in addition to increase converting means.
The direct current comprehensive state monitoring device intake uses original system auxiliary contact, shares with original system, and compatible sky connects
Point input and 24V input, vary without original system design when especially legacy system being transformed.
The direct current comprehensive state monitoring device can be showed by main screen monitor display and split screen monitor display or computer
Field input switch correlation setting, keeps equipment easy to use and meets more use occasions.
The direct current comprehensive state monitoring device includes hardware and corresponding software, provides external interface abundant, and use
NAND solid-state memory, storing data realize double copies, and protection data are reliable, do not lose.
The direct current comprehensive state monitoring device can effectively monitor each switch state, export alarm signal for error condition
Number, and energy prompt switch operation order is forgotten after avoiding a variety of consequences also caused by operating mistake, such as battery maintenance operation
Note closes cell switch etc., avoids the generation of major accident.
