Embodiment
Along with developing rapidly of electronic technology, mechanics of communication and computer technology, and the actual needs of electrical network electric energy metrical monitoring, blank that the realization camera head is made a video recording, the electricity anti-theft system of negative control terminal copy reading pattern has come out gradually.This GPRS/CDMA/3G large user's terminal with advanced level, in terminal, anti-electricity-theft realization and the various communication technology are combined, realized networked anti-electricity-theftly, carried out anti-electric theft monitoring by the mode of IMAQ, remedied to a great extent the large blank of current anti-theft electricity technology.
For reaching the flexibility of hardware configuration, the utility model adopts modular mentality of designing.As shown in Figure 1, the utility model comprises microcontroller, data acquisition unit, data processing unit, parameter setting and query unit, memory cell, control unit, local function unit, terminal maintenance unit, monitoring unit, ambient temperature detecting unit, smoke detection unit and transfer of data communication unit, monitoring unit links to each other with the main USB interface of microcontroller by camera, and with the stealing picture that gathers or video information transmission to microcontroller; The ambient temperature detecting unit reaches microcontroller with the temperature value that gathers by the AD port by temperature sensor, is used for the detection of operating ambient temperature; The smoke detection unit is crossed the IO port by temperature sensor with the smog information exchange that detects and is reached microcontroller, is used for the safety detection of the on-the-spot smog situation of electricity consumption; The transfer of data communication unit adopts the plug and play type communication module, is used for the transmission of image and monitor data.
As shown in Figure 2, mainly be to comprise an external camera on the monitoring unit hardware, this camera is with the software that can resolve the data of being sent by the utility model, and links to each other with microcontroller by USB interface, is responsible for Real Time Monitoring is carried out at the scene.
The anti-electric theft monitoring function of this unit mainly realizes by software.Consider practical situations, this terminal for electric power system of the utility model can not be as the monitoring of market, had take in 7 * 24 hours, so trigger condition needs to judge, therefore the utility model need to carry out image or video acquisition when triggering is arranged, so this trigger condition need to be judged.
Basic working modes is divided into two kinds: when receiving the photographing command of the main website that checks meter, the unconditional triggering taken pictures; When the state of measuring gate of the present utility model changes, trigger and take pictures.
During work, camera is in standby mode for a long time, waits IMAQ to be triggered.
When receiving when checking meter the main website photographing command, the unconditional triggering taken pictures.After opening, namely initiatively triggers measuring gate IMAQ; Judge at first whether the photo of taking pictures last time receives that the main website that checks meter reads reading of issuing after finishing and confirms order.Confirm order as receiving, then trigger photographing command.Otherwise continue regularly to produce alarm, until receive the affirmation order.
Take pictures finish after, carry out IMAQ and compressing and converting form, send terminal to by USB, terminal is carried out this locality storage, produces the active reporting warning message, the notice main website that checks meter has photo to read.In alarm report information, comprise IP address of terminal, FTP service and log in the communication relevant informations such as port numbers, FTP login user name, password, photo read path.
Check meter after main website receives report and alarm, the Application standard File Transfer Protocol logs in terminal according to the relevant communication information in the warning information, obtains the photo that this is taken pictures.Read finish after, terminal issued to read confirms order.
Terminal is deleted this photo of taking pictures after receiving and confirming order, waits for the triggering of next time taking pictures.As not receiving that after taking pictures the main website that checks meter confirms order, then repeats the active reporting warning message in 20 minutes.Until receive the affirmation order.
This monitoring unit Application standard File Transfer Protocol, this agreement is mature and stable, can tabulate easily, and transmission resumes operation; Exploitation is easily saved a large amount of exploitation debug times.The process of reading can freely be controlled by main station system for reading meter, and the utility model active reporting information is few, avoids producing the flow waste.The main website that checks meter can read all or part of photo repeatedly, avoids a large amount of acquisition terminals that specially become to upload simultaneously the impact that image information causes the main website server of checking meter, and the transmission load can freely be controlled distribution by main station system for reading meter; The problems such as file covering of simultaneously also avoiding terminal active transmission photo to cause.
Collection and the compression to the simulation camera signals realized in this unit, is in order to reduce actual size volume of the present utility model.Used camera adopts the infrared type camera, even such night also can guarantee to adopt image; And have video and two kinds of monitor modes of picture, with applicable different communication mode.Moreover, angle arbitrarily be laid and be adjusted to this external camera can according to field condition, satisfies to greatest extent monitoring requirement.
