Description

The line feed terminals and its fault monitoring method for having image procossing and comparison function
Technical field
The present invention relates to Distribution Automation Technology fields, and in particular to a kind of feeder line for having image procossing and comparison function Terminal and its fault monitoring method.
Background technique
Line feed terminals are also referred to as FTU, have the function of remote signalling, telemetering, remote control, fault detection etc., at the same with upper level distribution master It stands communication, distribution system operating condition and various parameters, including switch state, electric current, voltage, power etc. is provided, route occurs Parameter when failure, and execute the order that distribution main website issues, is adjusted distribution switchgear and divide-shut brake and energy storage control System realizes the functions such as fault location, Fault Isolation and non-faulting region fast recovery of power supply.
With chip technology, computer network and the fast development of communication, the R & D design of line feed terminals compares into Ripe, each producer makes full use of advanced technology to develop the line feed terminals product for meeting distribution automation requirement, and reliability is more next It is more stable.But it because of China rural area and urban power distribution network distribution dispersion, has a large capacity and a wide range, and on-pole switch and line feed terminals are mostly to pacify The equipment on the column on high-voltage wire pole, mounting height is higher, and on-site maintenance is time-consuming and laborious, and there are larger security risks.State Net transport inspection department door also needs to carry out the activities such as the great spring and autumn inspection of project amount every year, causes the waste of manpower and material resources.
Summary of the invention
To solve the shortcomings of the prior art, the invention discloses a kind of with the feeder line of image procossing and comparison function end End and its fault monitoring method, the present invention have the advantages that high degree of automation, integrated level are high, maintenance work amoun is small.
To achieve the above object, concrete scheme of the invention is as follows:
A kind of line feed terminals having image procossing and comparison function, comprising: have the CPU of image procossing and comparison function Module, data memory module, communication module, Analog input mModule, switching value I/O module, power module, the data are deposited Storage module is connected with CPU module realizes that bidirectional data communication, the power module are electrically connected with CPU module, communication module respectively It is connected in its power supply;The Analog input mModule, switching value I/O module are electrically connected with CPU module respectively, for measuring route Electrical quantity, control on-pole switch divide-shut brake movement;The communication module is electrically connected with CPU module, and CPU module passes through logical Believe that module sends fault-signal to distribution main website.
The CPU module uses the hardware development platform based on DSP, and software aspects are equipped with corresponding image analysis and calculate Method is handled in real time for the digital signal to image stored in data memory module, and with default normal operation Under graphics standard value be compared.When difference exceeds predetermined difference value, on-pole switch and route failure situation are assert, such as Situations such as insulator dust stratification is excessive, short trouble occurs for route, on-pole switch divide-shut brake is not in place, CPU module pass through communication mould Block sends fault-signal to distribution main website.Dsp chip selects high-speed figure to handle chip, and hardware aspect considers that the outside of chip is total Cable architecture, the factors such as on-chip memory structure, DMA function, serial communication port and interchip communication ability.CPU module also needs Switch amount I/O module, Analog input mModule is wanted to carry out data acquisition, calculating and processing, and data information is sent to and is matched Electric main website, to reach the functional requirement of system entirety.
The data memory module is connected with CPU module, as the expansion external memory of dsp chip internal storage, Data memory module is divided into the area Liang Ge: subregion one and subregion two.Digital camera is adopted when subregion one is used to operate normally route The image information data of collection stores, and the image information data of digital camera acquisition is deposited when subregion two is used for route real time execution Storage.CPU carries out digital signal operation and processing to the image informations of two subregions of data memory module, and by processing result into Row compares.
The communication module is connected with CPU module, main to complete to work as real time execution image data using communication When difference is beyond setting difference between preset standard value, failure letter is sent to distribution main website by communication module from CPU module Number, so that personnel arrive in-situ processing abnormal conditions in time.
The Analog input mModule is connected with CPU module, for measuring voltage, electric current, frequency and the active, nothing of route The electrical quantity such as function, by calculating contrast judgement line fault section.
The switching value I/O module is connected with CPU module, if the digital input and output channel by main line with Phototube Coupling It constitutes, can effectively control the divide-shut brake movement of on-pole switch, and monitor that its location status changes in real time, and starting energy storage Journey issues fault-signal etc..
The power module is connected with CPU module, if being made of main line AC/DC conversion module, can be simultaneously communication module, On-pole switch divide-shut brake, line feed terminals operation etc. provide DC supply, and power supply output and input need to carry out electrical isolation.
Where digital camera is installed on on-pole switch as ancillary equipment on electric pole, it is used cooperatively with line feed terminals, with Just monitoring on-pole switch and inlet-outlet line route real-time operating conditions.Digital camera carries out image information using digital signal and adopts Collection, is connected by RJ interface cable with the data memory module of line feed terminals and CPU module, and the image that CPU module issues is received Desired signal instruction, carries out Image Acquisition.Acquired image data are transmitted to the data memory module of line feed terminals.
Has the fault monitoring method of the line feed terminals of image procossing and comparison function, by the normal of digital camera acquisition Digital image information is stored as standard value, the real-time digital image information that digital camera acquires is compared with standard value, such as When the difference of both fruits is more than pre-set standard deviation, CPU module sends failure letter to distribution main website by communication module Number.Specifically includes the following steps:
Step 1, digital camera acquisition operate normally image information;
Step 2, digital camera send the subregion one for operating normally image information to data memory module, as standard Value;
Step 3, distribution main website send image desired signal to CPU module;
Step 4, CPU module acquire real time execution image information to sending instructions under digital camera;
Step 5, digital camera send the subregion two of real time execution image information to data memory module;
Real time execution image information data is sent to CPU module by step 6, data memory module, is compared with standard value It is right, determine whether beyond preset difference value, if it is, turn in next step, if not, to go to step 4;
Step 7, CPU module send fault-signal and give distribution main website.
Beneficial effects of the present invention:
1, the operating status of real-time monitoring on-pole switch and route improves distribution network systems the degree of automation.
2, when route or switch break down, operation maintenance personnel can arrive in-situ processing in time, avoid fault spread Change.
3, it under route and switch normal operating condition, reduces artificial scene and checks the route frequency, reduce manpower and material resources Waste.
