阴极保护电位自动采集装置的研制

INTRODUCTION OF A DEVICE FOR AUTOMATIC COLLECTION OF CATHODIC PROTECTION POTENTIAL DATA IN CYCLIC WET-DRY ENVIRONMENTS

设计研制了一种用于干湿交替环境下,自动采集阴极保护电位数据的装置.该装置的内部电路采用低功耗的单片机设计,外壳采用耐压水密结构设计.通过压力开关控制工作状态,完成水下电位数据的自动采集;并通过多支银/氯化银参比电极实现不同深度、不同采样频率下,被测物表面不同位置阴极保护电位数据的测量和存储.结果表明,该装置达到了干湿交替环境下阴极保护电位自动采集的设计要求。

A device used for automatic collection of cathodic protection potential data in cyclic wet-dry environments was designed and manufactured. The inside circuit of the device was designed with a low-power single chip processor. The outer shell of which was pressure-resistant and waterproof. The device was controlled by a pressure switch to work underwater with several Ag/AgC1 reference electrodes. The cathodic protection potential data of different locations by different deepness and frequency were automatically measured and stored at regular intervals.
