摘　　要：受限于进口紫外成像设备的知识产权和昂贵的价格,高压电器绝缘故障检测设备缺乏。为解决该问题,设计一种基于STM32的低成本简易型紫外成像装置。该文基于紫外光谱特性和电晕放电检测机理,完成简易嵌入式紫外成像装置的总体硬件设计和软件设计。重点介绍紫外传感器的选型和高压驱动电路设计,并建立仿真模型对紫外采集电路进行验证。采用GPS/北斗双模定位系统,准确定位电晕放电位置。通过不同光源及距离下对表征紫外强度脉冲宽度进行测试,验证该装置测量紫外强度的有效性。In order to solve the shortage of insulation fault detection equipment for high voltage electrical apparatus due to the intellectual property rights and high price of imported ultraviolet imaging equipment,a low-cost and simple ultraviolet imaging device based on STM32 was designed.The paper studied the UV spectral characteristics and the corona discharge detection mechanism,and completed the overall hardware design and UV acquisition program design of the simple embedded UV imaging device.The selection of UV sensor and the design of high voltage drive circuit are introduced,and the simulation model is established to verify the UV acquisition circuit.The device adopts GPS/Beidou dual-mode positioning system to accurately locate the corona discharge position.The effectiveness of the device in measuring UV intensity was verified by testing the pulse width of the UV intensity under different light sources and distances.
