    摘要:

    為解決變電站安防設備簡(jiǎn)單、智能化程度低問(wèn)題,設計出基于機器視覺(jué)的一體化安防管控系統,安裝現場(chǎng)視覺(jué)控制器作為系統硬件前端信息采集中心,利用以太網(wǎng)實(shí)現各設備通信連接一體化,門(mén)電路和變電站周界環(huán)境終端電子相連接,檢測激光電子圍欄危險入侵檢測,序列巡檢圍欄編號,確定危險入侵圍欄位置,通過(guò)線(xiàn)性二次型調節器算法對機器人期望位姿和實(shí)際位姿之間的耦合關(guān)系實(shí)行解耦處理,將處理結果作為神經(jīng)網(wǎng)絡(luò )的輸入,輸出機器人移動(dòng)軌跡跟蹤控制結果,完成視覺(jué)識別定位,實(shí)現動(dòng)態(tài)物體監測、火苗、溫度等多種危險因素的自動(dòng)識別和預警。經(jīng)過(guò)實(shí)驗分析證明:系統通過(guò)機器視覺(jué)準確監測到了高溫設備的位置和溫度,并且響應性能良好,安防信號傳輸環(huán)境穩定,危險情況預判能力及預警能力較強,魯棒性好。

    Abstract:

    In order to solve the problem of simple and low intelligence of substation security equipment, an integrated security control system based on machine vision is designed. The field visual controller is installed as the front end information acquisition center of the system hardware. The Ethernet is used to realize the integration of communication and connection of all devices, and the gate circuit is connected with the terminal electronics of the substation perimeter environment. The laser electronic fence is detected for dangerous intrusion detection, and the fence number is inspected in sequence to determine the location of the dangerous intrusion fence. Through linear quadratic regulator algorithm, the coupling relationship between the desired pose and the actual pose of the robot was decouped, and the processing results were taken as the input of the neural network to output the tracking control results of the robot's moving trajectory, complete the visual identification and positioning, and realize the automatic identification and early warning of dynamic object monitoring, fire, temperature and other dangerous factors. The experimental analysis shows that the system can accurately monitor the position and temperature of high-temperature equipment through machine vision, and has good response performance, stable security signal transmission environment, strong ability to predict and warn dangerous situations, and good robustness.
