Abstract
The invention discloses a kind of emergent monitor of straight-flow system, including DC voltage monitoring modular, DC grounding monitor module, SMS transmission module and short message power module, the DC voltage monitoring modular and DC grounding monitor module input are all connected with direct current, DC voltage monitoring modular and DC grounding monitor module output end are all connected with SMS transmission module, SMS transmission module is also connected with short message power module, the emergent monitor of straight-flow system of the present invention can come into operation when direct current (DC) monitoring device is abnormal, substitute the status information and fault message of direct current (DC) monitoring device collection transformer station direct current system, and send these information to the mobile phone of operation maintenance personnel and regulation and control personnel, them are made still to monitor the straight-flow system of transformer station in the distance, the someone for avoiding transformer station is on duty, save a large amount of human and material resources.
Description
Technical field
The present invention relates to a kind of monitor, specifically a kind of straight-flow system is met an urgent need monitor.
Background technology
Nowadays the transformer station run is unattended substation.Conventional substation straight-flow system supervising device is straight in collection
After streaming system status information supervisory control of substation backstage and remote dispatching are delivered in meeting.Transformer station's operation maintenance personnel and regulation and control personnel can be with
Transformer station direct current system is monitored in the distance by SCADA system.When direct current (DC) monitoring device is abnormal, operation maintenance personnel and tune
Control personnel can not just obtain transformer station direct current system information, and it is on duty that transformer station is accomplished by turning someone, until direct current (DC) monitoring device is repaiied
It is good.
The content of the invention
Meet an urgent need monitor to solve what is proposed in above-mentioned background technology it is an object of the invention to provide a kind of straight-flow system
Problem.
To achieve the above object, the present invention provides following technical scheme：
A kind of straight-flow system is met an urgent need monitor, including DC voltage monitoring modular, DC grounding monitor module, short message sending
Module and short message power module, the DC voltage monitoring modular and DC grounding monitor module input are all connected with direct current,
DC voltage monitoring modular and DC grounding monitor module output end are all connected with SMS transmission module, and SMS transmission module is also connected with
Short message power module.
It is used as further scheme of the invention：The SMS transmission module also connects operation maintenance personnel mobile phone by antenna.
Compared with prior art, the beneficial effects of the invention are as follows：Straight-flow system of the present invention meets an urgent need monitor can be in direct current
Supervising device comes into operation when abnormal, substitutes the status information and failure letter of direct current (DC) monitoring device collection transformer station direct current system
Breath, and these information are sent to the mobile phone of operation maintenance personnel and regulation and control personnel, them is still monitored transformer station in the distance
Straight-flow system, it is to avoid someone of transformer station is on duty, saves a large amount of human and material resources.
Brief description of the drawings
Fig. 1 is block diagram of the invention.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
Referring to Fig. 1, in the embodiment of the present invention, a kind of straight-flow system is met an urgent need monitor, including DC voltage monitoring modular,
DC grounding monitor module, SMS transmission module and short message power module, DC voltage monitoring modular and the DC earthing prison
Survey module input and be all connected with direct current, DC voltage monitoring modular and DC grounding monitor module output end are all connected with short message hair
Module is sent, SMS transmission module is also connected with short message power module.
SMS transmission module also connects operation maintenance personnel mobile phone by antenna.
The present invention operation principle be：The emergent monitor of straight-flow system is divided into DC voltage monitoring modular, DC earthing prison
Survey module and SMS transmission module.
DC voltage detection module is from dc bus collection voltages and shows in real time, at the same it also have dc bus overvoltage and
Undervoltage alarm function, when dc bus is over-pressed or under-voltage, it can export idle contact to SMS transmission module.Dc bus mistake
Pressure and under-voltage warning value can be set according to actual needs.
DC grounding monitor module is also from dc bus collection voltages, and it is by a balanced bridge and an electric current relay
Composition, when dc bus plus earth or negative pole ground connection, the electric current relay being connected on balanced bridge has electric current to flow through, then
The contact of electric current relay.The contact of electric current relay is connected similarly to telecommunications sending module.
SMS transmission module receives the idle contact signal of DC voltage monitoring modular and DC grounding monitor module, and by this
A little signals are with the mobile phone that power transformation O＆M operator on duty and regulation and control personnel are sent in the form of short message.SMS transmission module has 8
The input contact of definable.The overvoltage alarm inputted by DC voltage monitoring modular, under-voltage alarm are used；By direct current
Alert to the straight polarity direct current of grounding monitor module input, the negative ground connection of direct current alerts.Also remain after 4 spare contacts are available for and use.
Short message power module provides reliable and stable power supply for telecommunications sending module.
